There's no denying that the world has shrunk. How? Well, everything is connected. From the smartphone ecosystems to satellites, aerospace dynamics, and whatnot, we thrive in an era of technological advancements. Many simple yet ubiquitous inventions have propelled our tech-enabled growth, and one of them is antennas. These simple machines are useful beyond our imagination, but to ensure antennas work efficiently within their expected range, antenna measurement systemsare used by manufacturers.

Antennas play a pivotal role in modern communication systems, enabling wireless connectivity across various industries. However, designing and optimizing antennas require precise measurement techniques. Antenna test systems provide invaluable insights into antenna performance, radiation patterns, efficiency, and other essential parameters. By accurately assessing these characteristics, engineers can refine designs, troubleshoot issues, and meet stringent performance standards.

Components of Antenna Measurement Equipment

Antenna measurement equipment consists of several key components, each serving a specific purpose. These include:

Positioner: The positioner allows controlled movement of the antenna during testing, enabling measurements at different angles and orientations. It ensures accurate data collection by precisely controlling the antenna's position.

RF Source: The RF source generates the radio frequency signal that powers the antenna during measurements. It provides a stable and adjustable signal to simulate real-world conditions.

Antenna Measurement Receiver: The receiver captures and analyzes the signals received from the antenna. It measures various parameters such as gain, radiation patterns, impedance, and polarization.

Measurement Software: This software facilitates data acquisition, processing, and analysis. It provides a user-friendly interface for controlling the measurement process, visualizing results, and generating reports.

I've been thinking about teletherics and mica, especially since the appendices for 3.02 is a pocket guide to telethric transduction.

Teletherics is an Un-based technology, and teletheric waves aren't Fold-safe; the appendices for 1.05 mention that they need to be converted for rebroadcast into the Fold along cables for that reason. So, you can't transmit teletheric waves through the Fold. This is also suggested by the fact that Kozma's agenda lists all her teletheric calls after she leaves Midst; she can't have done it before then, in the Fold.

Apparently, teletherics can involve mica. The art of Backpack and her teletheric equipment includes a parabolic dish that uses a shard of mica as a feed antenna. Seeing as teletheric receivers, such as Ginsberg's in the icon for 1.03 and Hieronymous's in art for 3.02, don't feature visible mica, I presume then that her equipment is using it for transmission. If teletheric waves are transmitted using mica, that may explain why they're not Fold-safe. Teletheric signals are, of course, created using specially-boculated electric currents. A mica antenna would interact with that, then radiate it to a receiving teletheric transducer.

As a sidebar, the breakdown of the word teletheric is also very interesting to me: tele- + aetheric. I wonder if the Un is as empty as it seems to be when in compared to the Fold. Perhaps there is some stuff out there in the Un that they have not yet learned to measure. Or, perhaps teletheric is aetheric in the sense of aether theory and the transmission of waves through a medium. Or, in the sense of luminiferous aether and old theories on the movement of light. Or, perhaps in the sense of the mythological personification of the bright upper sky.

If mica is capable of transmitting teletheric waves, how do teletheric signals interact with the mica fields of the Un? Radio engineering is not as simply as any old piece of metal can act as an antenna, there's electric currents and what-not, but in this fantasy world in which our understanding of teletherics and mica is limited, it is a question. (And who is to say that things don't work slightly differently in the cosmos.) Do teletheric signals interact with mica bergs at all? Does wild mica bounce those signals across the Un?

If mica transmits signals, waves, does it have resonance then? Does it vibrate? Do mica bergs make sound as they float through the Un, and is it audible? Or, does it resonate a tone that is below the typical threshold of human hearing, like the third sound of a superfluid?

Hell, while I'm asking questions. Can someone end up with the opposite of what Lark has with the Fold, where they can hear mica resonating through the Un? Is there some soul out there, cosmos whispering to them, who can hear its crystalline tones resonating out across the Un, or the sound of lightning in the Delta or unships passing through the upper Un bouncing off the bergs, or teletheric signals transmitting out through the mica?

But, I'm getting ahead of myself: mica and teletherics and the transmission of sound. I think about teletherics and the shapes of all associated with it. Priathic notation reminds me of neumes, or even modern notation with beams but no stems. The impulses are tonal and have harmonics. Teletheric transducers uses fluted pipes, and those pipes make them look like small pipe organs. With that—

Does mica sing? Can you hear it if you tune in just right?

#I just LOVE asking questions about the way a fictional world works knowing I will never get answers. It's just FUN for me to think about.#What is the material reality of the cosmos!! It's fun to spin questions out of it!#Midst #Midst podcast #Midst things

Cold-Operations Dope, wrapped in a thick insulated jacket to stem heat loss, as well as providing a small degree of extra protection from enemy fire. This does necessitate the movement of the antennae to the head unit, with communication equipment housed in its own insulated covering.

Aside from the jacket, the frame is fairly similar to factory stock, with just snow-shoes and smaller leg vents marking it as different. Armament is a practical 40mm mech-scale assault rifle, supplemented by the standard chest mounted IR laser and a shoulder mounted box holding a pair of optical, wire guided missiles, with four smoke grenades on top of that.

Part of the simplicity of the alteration is just a cost-cutting measure - Cold-Op mechs usually aren't produced in great numbers, so using off the shelf components helps limit cost increases that often come with specialised units like this.

So, and correct me if I'm wrong, this is the only completely secure way to communicate over the internet:

1. Get a second computer which you will from now on never connect to the internet nor in any way allow to talk with any other computer, including flash drives, cables, Bluetooth, whatever.

2. Get it inside a Faraday cage that has an airlock type door so that you can always keep it closed.

This is because even of you rip out the antennas on a device, all modern motherboards have a backdoor which allows any government agents with proper equipment to compromise it via short range radio.

For good measure, get that computer its own power supply separate from the grid, to truly air gap it from the internet.

3. Anything which ever appears on any computer or phone can immediately be considered known to every security agency in the world, since all modern devices have backdoors put there for that reason.

Therefore, install on the other computer an encryption program(best if you make it yourself), whose resulting meaningless jumble of digits you by hand copy over to send to whoever needs it, presuming you gave them the key to decrypt it irl scribbled on a note or via the usual public private key method.

If any of this could be made simpler, please tell me, but I'm pretty sure that it can't.

Study Offers Improved Look at Earth’s Ionosphere

New measuring techniques will enable improved measurements of the Earth’s ionosphere, a key to studying and reducing the impact of space weather.

Radio signals have been used to study the density of plasma since the 1920s. Transmitting radio sources include ground-based ionosondes (special radar for the examination of the ionosphere), astronomical phenomena such as pulsars and more recently spacecraft signals used for transmitting data. For example, Global Positioning Satellites (GPS) radio signals are used to measure the density of Earth’s ionosphere. However, the response of the radio signal to the ionospheric plasma is more complicated than simply varying as a function of density. The Earth’s magnetic field affects its electromagnetic wave fluctuations as well. For example, Faraday rotation is a well-known phenomenon, as shown in the image above. But, as a technique for measuring magnetic field, Faraday rotation is limited to just the portion that is oriented in the correct direction. Our discovery complements Faraday rotation enabling a complete measurement of magnetic field strength.

“We discovered that the magnetic field was introducing noise to radio signals. The immediate impact of this work is to enable improved measurements of the Earth’s ionosphere. Additionally, all of the adverse conditions discussed about the hazards of space weather ultimately are driven by the Earth’s ionosphere responding to the Sun’s plasma,” said Elizabeth Jensen, Planetary Science Institute Associate Researcher Scientist and lead author of “The Hunt for Perpendicular Magnetic Field Measurements in Plasma” that appears in The Astrophysical Journal. “By reducing the error in GPS signals from the horizon and expanding the coverage to the poles, issues with communication fidelity losses are immediately improved.”

The effect of the plasma’s perpendicular magnetic field on radio propagation is shown in the image below. “We have discovered how to improve communications between the Earth and spacecraft; how to measure the strength of the magnetic field in space plasmas, an important result for improving space weather predictions; and how to obtain magnetic field measurements from some older archived spacecraft data,” Jensen said. “This is with our breakthrough discovery on how to isolate the contribution of the magnetic field perpendicular to the signal path in radio data.”

Space weather prediction, the physics behind destabilizing the ionosphere by the Sun’s plasma, is dominated by the temperature, velocity, density, and magnetic field of the plasma arriving from the Sun. The greatest source of error in these space weather models derives from the lack of magnetic field measurements in the intervening space between the Sun and the Earth. Improving our ability to predict space weather, via improved magnetic field measurements, enables reducing the costs from these adverse conditions.

“Here on Earth, we are primarily concerned with space weather. Space weather consists of the response of the Earth’s plasma regions to the plasma released by the Sun. Adverse conditions from this interaction include satellite damage, irradiating personnel not just in the space station but on flights near the poles, poor communications from a loss of signal fidelity impacting aircraft and other GPS-dependent equipment, for example self-driving vehicles, and damage to equipment such as power lines or subsea cables,” Jensen said.

This work was supported by Planetary Science Institute and University of Utah facilities. Collaborators Jamesina Simpson and Yaser Rahmani put in their personal time for this effort. Jensen was self-funded through her company, ACS Engineering & Safety.

Trial Eight Test Report

Subject: L0294

Pre-treatment Notes: L0294 is a female Ymir's group wasp weighing approximately 95 kg and measured at 2.4 meters. Most of its head has been overtaken by growths from a species of fungus believed to have convergent evolved alongside Earth's Ophiocordyceps unilateralis. Both of its antennae had taken significant damage and its thorax and abdomen are severely bloated. Roughly half of the hair that would normally cover its body is missing, and its wings are torn in multiple places. L0294's behavior is described as lethargic, showing little interest in its surroundings.

Treatment Administered: Prototype A9

Results: Subject L0294's fungal growths turned black upon being administered its first dose of Prototype A9, and within hours, L0294 ceased its attempts to climb the walls of its enclosure. Over subsequent doses of Prototype A9, L0294's body became increasingly discolored, eventually turning a dark shade of gray. Additional tissue began to grow on top of L0294's fungal growths. L0294 has become more aggressive, but has not regained its instinctual burrowing behaviors.

Current Status: Alive

Recommendations: Upgrade the air filtration system in L0294's containment. Its fungal growths have begun to secrete a dark purple mist which contain its spores. Any personnel entering its containment chamber are advised to equip full biohazard gear. Additional tests with sedatives may be administered to make L0294 more compliant with further experimentation.

Submitted to: Agent Mobius M. Mobius

Are EMF’s safe? (come, child, ruin your night)

y’all ready for this? I’m not anti-5G, btw turn your wifi off before bed and maybe stop keepin’ ya phone so close all the time

But like... why, though?

I've had my suspicions about cell towers being hazardous to health for a few years now and felt convinced enough to not bother researchin' it for confirmation. Now that I'm blah blah blah, I decided to actually bother. Since it got kinda heavy, I had to ask myself if I should put in hella more effort creatin' a damn research report of sorts for y'all asses present the info for others like it's a damn PSA. And my conscious won. T~T

But like... what, though?

A base station (aka: cell phone tower) is that shit you see everywhere but never notice. It's usually tall af and has panel antennas on it. It's "used for the transmission and reception of the radio signals between the mobile phones and the network." The problem with 'em is the electromagnetic field (EMF) their equipment can give off... for half a mile. 😐

In short, they've been found to cause health problems. Like cancer. 🤷🏿‍♂️

Fun fact, panel antennas can be installed on the roof/side of buildings that may be directly across the street from someone's workplace... with the antenna at their elevation. 🤷🏿‍♀️

Real Quick

For those who don’t trust EMF-Portal, it (sometimes) has links to the study/article. Full-text PDF can be requested directly from the authors on ResearchGate.net’s article for the study. Full-text PDF can (usually) be found online in English and German with the right search.

5 Studies

V/m = volts per meter 7191 cancer deaths were selected according to the above mentioned criterias out of a total of 22,493 cancer deaths. The most significant causes were lung cancer (19.6 %), stomach cancer (14.1 %), prostate cancer (12.6 %), and breast cancer (11.5 %). The mean electric field intensity of the measurements in 2008 was 7.32 V/m, varying from 0.4 to 12.4 V/m. At a distance of up to 100 m [328.08 ft], the absolute number of deaths was 3569, (49.6 % of all deaths), the mortality rate was 43.4 persons per 10,000 [0.43%] and the relative risk was 1.35 in relation to the mortality rate of 32.1 per 10,000 [0.32%] inhabitants of the entire Belo Horizonte municipality [in Minas Gerais, Brazil]. A mortality rate of 34.8 per 10,000 [0.35%] inhabitants was observed for the residents living within 500 m [1,640.42 ft] of the base stations; this rate decreased for residents living farther from the base stations.

ResearchGate.net’s article

The result of the study [of 967 permanent residents] shows that the proportion of newly developing cancer cases was significantly higher among those [320] patients who had lived during the past ten years at a distance of up to 400 metres [1,312.34 ft] from the cellular transmitter site, which has been in operation since 1993, compared to those patients living further away, and that the patients fell ill on average 8 years earlier. In the years 1999-2004, ie after five years' operation of the transmitting installation, the relative risk of getting cancer had trebled for the residents of the area in the proximity of the installation compared to the inhabitants of Naila[,Germany,] outside the area.

9 cancer cases were observed in the first period 2000 - 2004 and 14 cases in the period 2005 - June 2007 among [1,283] residents living within a radius of 400 m [1,312.34 ft] to a mobile phone base station [in Germany (Hennen, suburb of Iserlohn, Westfalia)]. The mean age of disease onset was 59.2 years in the first period and 59.3 years in the second period in comparison to the expected value of 66.4 years evaluated from the Saarland Cancer Registry. The authors concluded, that a statistically significant increase of cancer incidence was observed 5 years after the base station has been started operating.

Area A: ≤ 350 m / 1148.3 ft from base station Area B: > 350 m / 1148.3 ft from base station Of the 622 people of area A, 8 cases of different kinds of cancer were diagnosed in a period of one year (from July 1997 - June 1998). The cancer incidence rate was 129 cases per 10,000 [1.29%] persons per year in area A compared to 16/10,000 [0.16%] in area B and 31/10,000 [0.31%] in the town of Netanya [in Israel]. Relative cancer rates for females were 10.5 for area A, 0.6 for area B and 1 for Netanya. The authors conclude that the study indicates an association between increased incidence of cancer and living in proximity to a mobile phone base station.

Took forever to get this damn infographic just right. >.>

A long-term study was conducted in Germany to investigate the influence of a mobile phone base station on neurotransmitters under true-to-life conditions. µW/m² = microWatts per square meter 24 out of 60 participants were exposed to a power density of < 60 µW/m², 20 participants to 60 - 100 µW/m², and 16 participants to more than 100 µW/m² . The values of the stress hormones adrenaline and noradrenaline grew significantly during the first 6 months after starting the GSM base station; the values of the precursor substance dopamine substantially decreased in this time period. The initial condition was not restored even after 1.5 years. Due to the not regulable chronic difficulties of the stress balance, the phenylethylamine levels dropped until the end of the investigation period. The effects show a dose-effect relationship and are situated far under the valid limit values.

ResearchGate.net’s German article EMF:data page (German)

While I did find 17 different figures for it, I’mma save myself the bother of describin’ dat noise and not include ‘em thanks~.

But what does the FCC say?

FCC.gov’s conclusion seems to be that they’re generally safe for civilian life as long as you don’t get close and aren’t directly in front of the antenna’s trajectory (don’t climb a fuckin’ tower or enter those rooms/buildings). A very “it’s fine” set of conclusions tbh. Hella contrasted by other sources.

Nonetheless… below is the index...

FCC’s RF Safety FAQ Index:

What is "radiofrequency" and microwave radiation?

What is non-ionizing radiation?

How is radiofrequency energy used?

How is radiofrequency radiation measured?

What biological effects can be caused by RF energy?

Can people be exposed to levels of radiofrequency radiation and microwaves that could be harmful?

Can radiofrequency radiation cause cancer?

What research is being done on RF biological effects?

What levels are safe for exposure to RF energy?

Why has the FCC adopted guidelines for RF exposure?

How safe are mobile phones? Can they cause cancer?

How can I obtain the specific absorption rate (SAR) value for my mobile phone?

Do "hands-free" ear pieces for mobile phones reduce exposure to RF emissions? What about mobile phone accessories that claim to shield the head from RF radiation?

Can mobile phones be used safely in hospitals and near medical telemetry equipment?

Are wireless and PCS towers and antennas safe?

Are cellular and other radio towers located near homes or schools safe for residents and students?

Are emissions from radio and television antennas safe?

How safe are radio antennas used for paging and "two-way" communications? What about "push-to-talk" radios such as "walkie-talkies?"

How safe are microwave and satellite antennas?

Are RF emissions from amateur radio stations harmful?

What is the FCC's policy on radiofrequency warning signs? For example, when should signs be posted, where should they be located and what should they say?

Can implanted electronic cardiac pacemakers be affected by nearby RF devices such as microwave ovens or cellular telephones?

Does the FCC regulate exposure to radiation from microwave ovens, television sets and computer monitors?

Does the FCC routinely monitor radiofrequency radiation from antennas?

Does the FCC maintain a database that includes information on the location and technical parameters of all the towers and antennas it regulates?

Which other federal agencies have responsibilities related to potential RF health effects?

Can local and state governmental bodies establish limits for RF exposure?

Where can I obtain more information on potential health effects of radiofrequency energy?

The Government Accountability Office (GAO) prepared a [2012] report of its investigation into safety concerns related to mobile phones. The report concluded that further research is needed to confirm whether mobile phones are completely safe for the user, and the report recommended that the FDA take the lead in monitoring the latest research results.

Professional Opinion...

Safe Distance from Cell Towers…

It is also difficult to predict a safe distance from cell towers. For example, cell towers are designed to transmit most of their radio frequency (RF) energy horizontally. Some areas below the tower may have lower levels than locations farther away that are more in line with the vertical height of the antennas. The exposure from a cell tower will depend on the type of antennas, the number of antennas, how much the antennas are actually being used, the time of day, etc. The distance needed to reduce exposures down to the General Public Precautionary Level of 100 microwatts per meter squared (μW/m²) is often around a quarter of a mile (1320 feet) or more. Due to the uncertainty, on-site testing with a broadband RF test meter is strongly recommended. A German study reported that people living within 400 meters (1312 feet) of cell towers had over 3 times the normal rate for new cancers (City of Naila 2004). In an Israeli study, the relative risk for cancer was about 4 times greater within 350 meters (1148 feet) of the cell tower (Wolf et al. 1997). Based on findings like these, a minimum safety distance of 1/4 mile (1320 feet) might be considered prudent. (...) The suggestions for safety distances in this chart are generally based on Michael Neuert’s [engineer, licensed electrician, and health educator] professional on-site testing of the various EMF sources in the San Francisco Bay Area since 1992.

i know what i said

Based on the accumulated evidence, we recommend that IARC [the International Agency for Research on Cancer] re-evaluate its 2011 classification of the human carcinogenicity of RFR [radio-frequency radiation], and that WHO [the World Health Organization] complete a systematic review of multiple other health effects such as sperm damage. In the interim, current knowledge provides justification for governments, public health authorities, and physicians/allied health professionals to warn the population that having a cell phone next to the body is harmful, and to support measures to reduce all exposures to RFR.

—Risks to Health and Well-Being From Radio-Frequency Radiation Emitted by Cell Phones and Other Wireless Devices; Front Public Health (2019 Aug 13); NCBI

Lookup (or pull out) your cellphone’s manual and search for the sections on “radio frequency exposure” and “Specific Absorption Rate (SAR) information” to see how close the phone can safely be kept near your body… and that it should be kept away from “the bellies of pregnant women and for teenagers, away from the lower abdomen.” 😐

For an informative giggle, here’s the “Harmful Cell Phones” segment from season 7 of The Colbert Report.

Here is why Your Jaguar’s Radio is not working

Now a days cars are not only equipped with better safety features, but also some accessories that make you feel refreshed while travelling in a car. One of such accessories is your car’s radio. A radio makes easy to pass time while travelling for a long time in a car. But imagine if you are going for picnic with your whole family and you have to travel a long distance, but unfortunately your radio is not working properly or not working at all. Then this long time travelling would become severely frustrating not only for you but for all of your family members. Kids would get easily bored and irritated. A malfunctioning radio can spoil your mood. If your radio is no working, then you can get it fixed, but before that you must know what can be the culprit in this case.

Role of radio in happy driving

Now a days everyone know what a radio is. It is one of the old means of infotainment. But still radios are in use. In cars, while travelling it sill provides you some necessary information and entertains you by music and entertaining programs. A radio provides the audiences to listen the radio shows and podcasts. A radio makes a long time taking journey to simpler and enjoyable driving. So a radio can be a complete travel companion, because every time you switch on your radio while driving, you always have a very good driving experience. A radio always make your travelling more enjoyable by entertaining the whole time you are driving your car. Nearly all jaguar car users’ use radio, so naturally, malfunctioning of radio can make them frustrated. So you must know what are the possible causes the malfunctioning of radio before diagnosing the issue.

What causes the radio to die?

A radio is an electronic accessory component in a car. It depends on electricity to run. So malfunctioning of radio can be an electrical issue. If it would not get electricity of proper voltage, then it would not run at all. Here are some reasons that commonly causes radios to stop working.

Fuse blown out

Fuse are protective components present in electrical devices that protects them from power surges. Whenever more electrical power passes through it, it melts and breaks leading to open circuit. So the power supply can be stopped and the electrical device is saved from high power. Fuse allows the current to pass, but if it is blown, then the current would not pass in its circuit and the device would stop working. Blown fuse is the most common culprit of a malfunctioning radio. If you encounter such problem then check its fuse first.

Damaged antenna

Radio receives signal by the help of antenna and processes it to get the audio. If your radio is no working, then problem can be in the antenna itself, because without antenna signals would not be received properly and radio would not work.

Faulty wiring

A faulty wiring is usually found in third party installations of stereos done in cars because mostly, those stereos are not designed to work in that car. So these are wrongly installed, which easily get loosened with time by vibrations of the car. Due to loose vibrations, the radio stops working properly.

Faulty speaker

A speaker makes the sound audible to every passengers in the car. Without speaker, the radio would of no use. If the speaker is damaged or its contacts with wires is loosened then the speaker would not produce sound properly. The radio displaying normally but no sound from speaker is a very good sign of faulty speaker.

Problems in the battery or its connections

If the battery is dying or got weak or its connections with the car is loosened, then a disruption on power flow occurs, due to this problem the radio have a feature called anti-theft measure which shuts off the radio and conserves the energy from the battery. Then you will find that the display in the radio is different than normal.

Conclusion

If the radio is malfunctioning, then first check the fuse inside it. A blown fuse is to be replaced. Then check the wirings, the speaker and the antenna. Every malfunctioning in radio is to be fixed by car professionals. You can contact your dealer to have them fixed.

Cost and operational availability of the main aeronautical assets

Fernando Valduga By Fernando Valduga 10/09/2022 - 12:00 in Military

The correct evaluation of a combatant force, - whether surface ships (crusaders, destroyers and frigates), submarines, combat tanks (MBT) or aircraft - needs to take into account, in addition to the expenditures with the development of the project and acquisition of the means, its operational cost and availability.

By way of example, the current nuclear propulsion missile launchers (SSBN) submarines have an operational availability of approximately 50%. Not for any other reason, the U.S. Navy hopes, with the new "Columbia" class, to increase this percentage in relation to the "Ohio" class, allowing the current number of 14 vessels with 24 SLBM (Submarine-Launched Ballistic Missiles) missiles each to be replaced, without prejudice to efficiency, by 12 units equipped with 16 SLBM missiles

On the other hand, the operational availability of the 400 ICBM (Inter-Continental Ballistic Missiles) LGM-30 Minuteman III is close to 95%. In fact, this is exactly the synergy of the nuclear triad, since each vector, - SLBM launched from submarines, ICBM in reinforced silos and ALCM (Air-Launched Cruise Missiles) fired from strategic bombers -, has confrontational advantages and disadvantages, which make the "everything" more efficient than each of the types of vectors separately considered

In the particular case of combat aircraft, in addition to their operational capacity, it is always necessary to evaluate the operational cost and availability, including the measurement of life cycle values.

In 2012, the most reliable numbers then available indicated that, as for the first parameter, the Eurofighter Typhoon (US$ 18 thousand/hour of flight) spends little more than twice as much as a Lockheed F-16 Falcon (US$7.7 thousand/hour), more than three times in relation to the Saab Gripen C/D (US$ 4.7 thousand/hour) and

When it comes to 5th generation aircraft, with stealth capability, the values are even higher, forcing a Lockheed Martin F-35A Lightning II to consume about US$ 38,000/hour of flight. Already the hourly cost of flight of a Lockheed Martin F-22 Raptor, - the most capable and sophisticated fighter in service on the U. S. Air Force (USAF) -, can revolve around an impressive $70,000, about 10 times more than the operating costs of the Gripen I/F (these values are current).

The great impact of costs comes from several factors (considering the high complexity of the Raptor), but mainly from the sophisticated coatings of the aircraft, which expand its stealth capacity. These coatings are made of special materials that absorb the energy radiated by radars, and the "skin" of the fighter also has a complex internal structure in the form of a hive. The F-22 also incorporates a number of innovative systems that substantially increase maintenance costs, such as the complex Radar Warning Receiver, which includes more than 30 antennas scattered throughout the aircraft.

Thus, each F-22 requires more than 40 hours of maintenance for each hour of flight, greatly reducing its operational availability. To give you an idea, allegedly only 40-50% of the F-22 fleet (accounted in 2021 on a total of 165 aircraft in the USAF and another 20 in the Air National Guard - ANG, according to 'The Military Balance 2021", IISS, London, ps. 58-59), or approximately 90 aircraft, is completely able, at a given time, to carry out

Very differently from what common sense deduces, fuel expenses have very little impact on the composition of these values, not only in the case of the Raptor but also in the case of other equally complex aircraft (the F-35 Lightning II stealth light fighter and the Stealth Northrop Grumman B-2 Spirit bomber, for example). Fuel expenses vary according to numerous factors, but, on average, an F-22 consumes 2,000 to 3,000 gallons per hour, representing an average expenditure of about US$ 5,000/hour of flight, that is, less than 10% of the total value.

Another important factor that aircraft operators account for is the so-called "cost per life cycle", referring to the expenditures of an aircraft during the entire time lapse foreseen for its operation. In the case of Raptor, it is estimated at $334 million, meaning that each F-22 will demand this amount throughout its period of operational activity.

In terms of operational availability, as a rule, the more complex and capable the combat plane, the lower its percentage degree of availability. Thus, despite being the Grumman F-14D Super Tomcat (with its AIM-54 Phoenix missiles guided by active radar and with more than 200km of range) more capable than the F-18E/F Super Hornet (which replaced it), its operational availability (depending on the number of man-to-home hours required for maintenance) was lower. Thus, the replacement undertaken by U. S. Navy enabled a greater number of aircraft available for emergency use.

In the same sense, the superiority of the Boeing F-15 Eagle (never shot down in aerial combat) and its latest version, the F-15EX Eagle II, over the latest version of the F-16 Falcon remains indisputable. However, the costs of its flight hour are much higher and its operational availability (number of fleet aircraft ready for combat) is much lower, requiring the USAF to have a "mix" of aircraft of both models, conceiving an indispensable complementarity between combative capacity and operational availability.

The Brain: A Pressure Symphony of Classical and Quantum

Imagine the brain as a grand orchestra, with neurons acting as individual musicians. Quantum mechanics could be the hidden conductor, orchestrating the flow of information in a way that classical physics alone cannot explain. Just as a conductor can coax a powerful and moving performance from an orchestra, the brain, if it leverages quantum phenomena, could be capable of extraordinary feats of information processing and creativity. The more we understand the score – the laws of physics, both classical and quantum – the better equipped we are to appreciate the magnificent performance that is capable of the human brain.

Imagine the human brain not just as a complex network of neurons, but as a sophisticated quantum reservoir computer. This mind-bending hypothesis posits that the brain utilizes the bizarre laws of quantum mechanics to enhance its processing capabilities. While still theoretical, it opens doors to a universe of possibilities about how our brains might truly function.

Quantum Mechanics: The Maestro of the Dance:

Unlike the billiard-ball certainty of classical physics, quantum mechanics governs the microscopic world, introducing fascinating concepts like:

Superposition: A mind-boggling state where particles can exist in multiple states simultaneously, like a coin spinning on its edge, heads and tails at once, until a measurement forces it to choose.

Entanglement: Two particles become eerily linked, sharing a fate regardless of distance. Imagine flipping two coins, and no matter how far apart they are, they always land on the same side.

Plausible Mechanisms: Where Quantum and Classical Collide:

Could these phenomena play a role in the brain's remarkable abilities? Here are some possibilities grounded in current research:

Microtubules: Quantum Stagehands: Microtubules, tiny cellular structures, might be the key players. These hollow tubes could act as waveguides, channeling quantum information within the brain. Imagine them as microscopic fiber optic cables, but for the bizarre world of quantum phenomena.

Quantum-Assisted Signal Processing: Brain function relies on the rapid exchange of information between neurons. Quantum effects could potentially supercharge this communication, facilitating faster or more efficient signal transmission. Think of it as a quantum boost for our neural network, allowing information to flow with unprecedented speed and efficiency.

Stochastic Resonance: Embracing the Noise: Our brain might utilize a fascinating phenomenon called stochastic resonance. Imagine weak signals buried in noise. The brain could amplify these faint signals by incorporating quantum noise, enhancing its ability to make decisions in ambiguous situations.

Non-local Information Processing: Accordance (https://www.tumblr.com/ultrimio/748348095336677377/analyzing-the-intriguing-phenomenon-of?source=share) suggests that the receiver's action can influence the sender's message. Could the brain, through some unknown mechanism, utilize this principle for non-local information processing, potentially explaining phenomena like telepathy? This is highly speculative, but it highlights the need for further exploration beyond established physics.

The Brain as a Quantum Interferometer: Decoding the Universe's Symphony:

The brain's intricate structure might even act as a quantum interferometer. Just like a classical interferometer splits light waves to reveal hidden information, the brain could interact with external waves, potentially including:

Hypothetical Pressure Waves: These theorized waves could ripple through the fabric of the universe itself, carrying energy and information across vast distances. Imagine the brain acting as an antenna, picking up these subtle cosmic whispers and deciphering their secrets.

Info-Quanta: The Building Blocks of Reality?: Some physicists propose that these pressure waves are composed of fundamental units called info-quanta (similar to the luminiferous aether), the very building blocks of information itself. The brain, as a quantum interferometer, could interact with these info-quanta, potentially gaining a deeper understanding of the universe's underlying code.

Additional info on the luminiferous aether: The concept of luminiferous aether refers to a theoretical substance that was once believed to fill the universe and act as a medium for the propagation of light and other electromagnetic phenomena. Initially proposed in the 19th century, the luminiferous aether hypothesis faced significant challenges and was ultimately refuted by experiments like the Michelson-Morley experiment, leading to the development of modern physics theories like the special theory of relativity. Despite being debunked, recent research has reignited interest in the aether, with some suggesting that it could potentially unify physics by explaining phenomena like dark matter and dark energy.

Unexplored Innovations: A Glimpse into the Quantum Future:

The implications of these ideas are mind-blowing:

Enhanced Cognition: Imagine a future where the brain, leveraging quantum phenomena, possesses an unimaginable processing power, leading to breakthroughs in fields like artificial intelligence and problem-solving.

Quantum-Inspired Communication: Perhaps the brain can directly interact with these pressure waves, facilitating communication beyond the limitations of space and time. Imagine telepathy becoming a reality, not through magic, but through the power of quantum mechanics.

Quantum Healing: If the brain can manipulate quantum processes at a cellular level, it could potentially influence biological functions and even facilitate healing on a deeper level. Imagine a future where diseases are tackled by harnessing the power of the quantum brain.

Challenges and Considerations:

While these ideas are captivating, significant hurdles remain:

Limited Evidence: Currently, there's no definitive proof that quantum processes directly influence brain function. Further research is needed to validate these hypotheses.

Technical Hurdles: Measuring and manipulating quantum phenomena within a complex biological system like the brain presents immense challenges. Imagine trying to study the behavior of subatomic particles in a constantly firing neural network!

Alternative Explanations: Many aspects of brain function can be explained by classical physics. It's crucial to explore all avenues before definitively saying the quantum world plays a central role.

A Symphony Awaits:

The exploration of the brain as a quantum reservoir computer and potential interferometer pushes the boundaries of our understanding. While the concepts remain speculative, focusing on plausible mechanisms and fostering interdisciplinary collaboration between physicists, neuroscientists, and quantum biologists holds the key to unlocking the brain's true potential. The future of neuroscience might reveal a fascinating symphony where classical and quantum mechanics intertwine

NASA orbiter snaps stunning views of Mars horizon

The spacecraft captured a series of panoramic images that showcases the curving Martian landscape below gauzy layers of clouds and dust. Stitched end to end, the 10 images offer not only a fresh, and stunning, view of Mars, but also one that will help scientists gain new insights into the Martian atmosphere.

The spacecraft took the images in May from an altitude of about 250 miles (400 kilometers)—the same altitude at which the space station flies above Earth.

"If there were astronauts in orbit over Mars, this is the perspective they would have," said Jonathon Hill of Arizona State University, operations lead for Odyssey's camera, called the Thermal Emission Imaging System, or THEMIS. "No Mars spacecraft has ever had this kind of view before."

How it was done

The reason why the view is so uncommon is because of the challenges involved in creating it. Engineers at NASA's Jet Propulsion Laboratory in Southern California, which manages the mission, and Lockheed Martin Space, which built Odyssey and co-leads day-to-day operations, spent three months planning the THEMIS observations. The infrared camera's sensitivity to warmth enables it to map ice, rock, sand, and dust, along with temperature changes, on the planet's surface.

It can also measure how much water ice or dust is in the atmosphere, but only in a narrow column directly below the spacecraft. That's because THEMIS is fixed in place on the orbiter; it usually points straight down.

The mission wanted a more expansive view of the atmosphere. Seeing where those layers of water-ice clouds and dust are in relation to each other—whether there's one layer or several stacked on top of each other—helps scientists improve models of Mars' atmosphere.

"I think of it as viewing a cross-section, a slice through the atmosphere," said Jeffrey Plaut, Odyssey's project scientist at JPL. "There's a lot of detail you can't see from above, which is how THEMIS normally makes these measurements.

Because THEMIS can't pivot, adjusting the angle of the camera requires adjusting the position of the whole spacecraft. In this case, the team needed to rotate the orbiter almost 90 degrees while making sure the sun would still shine on the spacecraft's solar panels but not on sensitive equipment that could overheat. The easiest orientation turned out to be one where the orbiter's antenna pointed away from Earth. That meant the team was out of communication with Odyssey for several hours until the operation was complete.

The Odyssey mission hopes to take similar images in the future, capturing the Martian atmosphere across multiple seasons.

Over the moon

To make the most of their effort, the mission also captured imagery of Mars' little moon Phobos. This marks the seventh time in 22 years that the orbiter has pointed THEMIS at the moon in order to measure temperature variations across its surface.

"We got a different angle and lighting conditions of Phobos than we're used to," Hill said. "That makes it a unique part of our Phobos dataset."

The new imagery provides insight into the composition and physical properties of the moon. Further study could help settle a debate over whether Phobos, which measures about 16 miles (25 kilometers) across, is a captured asteroid or an ancient chunk of Mars that was blasted off the surface by an impact.

NASA is participating with JAXA (Japan Aerospace Exploration Agency) in a sample return mission to Phobos and its sister moon, Deimos, called Mars Moon eXplorer, or MMX. Odyssey's Phobos imagery will be helpful to scientists working on both Odyssey as well as MMX.

IMAGE....This unusual view of the horizon of Mars was captured by NASA’s Odyssey orbiter using its THEMIS camera, in an operation that took engineers three months to plan. It’s taken from about 250 miles above the Martian surface – about the same altitude at which the International Space Station orbits Earth. Credit: NASA/JPL-Caltech/ASU
