Ljubov Rebane does not appear to refer to a widely recognized concept, person, or entity in my knowledge base up to October 2023. It might be a name, possibly of an individual, but without more context, it's difficult to provide specific information.

Local elevation refers to the height of a specific location above a defined reference point, typically above sea level. It can also refer to the height of a particular point compared to its immediate surroundings. In geographical terms, local elevation can be important for various applications, including: 1. **Topography**: Understanding the physical landscape, including mountains, valleys, and other features.

The Local Rapid Evaluation of Atmospheric Conditions (LREAC) System is a system designed to monitor and assess atmospheric conditions in a localized area, often for the purpose of improving public safety, enhancing weather forecasting, and supporting various operational needs. Generally, such systems can include a combination of technologies including weather sensors, remote sensing tools (like radar or satellite imagery), and data analytics platforms to provide real-time or near-real-time information about atmospheric phenomena.

Location-based software refers to applications and services that utilize geographical data to provide context-specific functionality or information to users based on their physical location. This technology leverages various data sources, such as GPS, Wi-Fi, cell tower triangulation, and Bluetooth beacons, to determine a user's position. Key features and applications of location-based software include: 1. **Navigation and Mapping**: Applications like Google Maps or Waze provide real-time navigation and route optimization based on the user's current location.

Lofting is a technique used in various fields, particularly in boat building, architecture, and industrial design, to create accurate, scaled representations of complex curved shapes. The goal of lofting is to produce full-sized templates from scaled drawings or sketches that can be used for construction or manufacturing. In boat building, for example, lofting involves transferring the lines of a boat (which are represented as curves on a 2D plane) into a 3D form.

A logistics center is a facility or hub that plays a crucial role in the supply chain management process. It serves as a centralized location for various logistics activities, including storage, transportation, sorting, and distribution of goods. Logistics centers are designed to optimize the flow of products from suppliers to consumers, streamlining operations to ensure efficiency and effectiveness. Key functions of a logistics center may include: 1. **Storage:** Maintaining inventory of goods until they are needed for distribution or sale.

A log-space computable function is a function that can be computed by a deterministic Turing machine (DTM) using logarithmic space in the size of the input.

Longest-Processing-Time-First (LPT) scheduling is a type of scheduling algorithm used primarily in operations research and computer science to allocate resources or schedule jobs based on their processing times. The fundamental principle of LPT is to prioritize tasks based on their duration, specifically scheduling the longest tasks first. **Key Characteristics of LPT Scheduling:** 1. **Prioritization**: Tasks are sorted by their processing times in descending order.

The Longley–Rice model, also known as the Longley–Rice propagation model, is a widely used mathematical model for predicting radio wave propagation, particularly in the context of terrestrial communication systems. Developed by Wilbur Longley and Paul Rice in the 1960s, the model is particularly relevant for calculating the path loss of radio signals over various terrains and conditions.

Long-range dependence (LRD) is a statistical property of time series or stochastic processes characterized by correlations that decay more slowly than an exponential rate. In other words, past values in a process influence future values over long time horizons, leading to significant dependence among observations even when they are far apart in time.

"**Lorraine**" can refer to different contexts. Here are a few: 1. **Geographical Region**: Lorraine is a historical region in northeastern France. It's known for its rich history, unique culture, and as a former duchy. The region has experienced various territorial changes over the centuries, particularly during periods of conflict such as the Franco-Prussian War. 2. **Culinary Term**: Quiche Lorraine is a famous dish originating from this region.

The "most prestigious French engineering school". Only 3 Nobels though as of 2019, the scientists are mostly at École normale supérieure (Paris). A gazillion CEOs ad politicians however.

Ciro Santilli studied there from 2010 to 2013.

Ciro considers him entering at Polytechnique a small miracle. First, on his second year of University in Brazil, he first had to fail to join the also good but not as good École centrales, which really annoyed him as he saw the "other good students" who wanted to go out get their wish. This also explains why there are so few students from his university going to Polytechnique in the late 2010's: most already went to other locations! Then, on his third year, he tried Polytechnique and got in despite feeling that the others who got in knew much more mathematics and physics than him. Rather, Ciro believes that he got in chiefly due to his intense passion for the sciences which he showed during the interview.

The miracle would have been even greater if it had happened in 2020. At this time, out of 10 Brazilians, 9 are from ITA, the "hardest to get into" university in Brazil, and also military like Polytechnique. Make no mistake, those students are amazing and deserve it without any doubt. But there is more to the story. It could be argued that many of them only go because they don't have any other choice of exchange program. Remember: Ciro had to fail applications on previous universities before getting into Polytech. Also, they don't get any Brazilian degree because ITA has no agreements with Polytechnique, and are therefore extremely likely to never come back. Not that Ciro thinks this is particularly bad for Brazil though, but it does make for a better deal for France overall as well. They also happen to have closer ties across cohorts of different years, and have managed to maintain a Google Doc with scanned past examinations (as of 2020 however, some/all of those examinations have been uploaded publicly, big kudos to them). Also almost all of them are software engineers, which is one of the few disciplines given at the relatively small ITA. This lack of diversity might not be ideal: if I were France, I would rather fish around all top Brazilian schools for "the best".

Besides the amazing funding/opportunities/alumni/staff loop which you can read about elsewhere, Polytechnique is amazing because you can choose what you will study every year to a very large extent.

This is in huge contrast to the crappy systems Ciro had seen e.g. in Brazil's Polytechnic School of the University of São Paulo, where students have to decide basically all their courses in huge packages, either at university entry (thus when they are completely clueless), or at a single point inside the university studies, changes being much harder.

Life quality was also amazing. Good free accommodation on campus and at the time a no-obligations scholarship for every foreign student great sport facilities. It seems that after Ciro left however more restrictions are added to the scholarships, what a shame! As of 2020 not everyone gets scholarships anymore it seems, mostly only loans that have to be paid back later. And those who are not poor have to pay Polytechnique scholarship fees on top of their living costs. And thus French austerity measures are undermining the greatest long term investment a country can possibly make: that of importing the very best students from other countries into yours. This after their host country has already spent 20 years raising and selecting them. And you won't even pay them 2 years of frugal existence to steal some of them them. Even if those students move away from your country later on, the contacts they made in your country mean they are much more likely to bring businesses over. But some will stay. Basically, France is becoming more like the United States.

This also makes it much more difficult for those students to do a PhD afterwards, where they would get paid very little, and are unable to pay their student debts. A PhD would be where they would possibly bring more of the next big thing to your country. Instead, they are much more likely to just go work for some big American company data wrangling and bring nothing to your country but their student debt dividends instead, which they will be pay to pay for in one year with those amazing salaries. And unsurprisingly many go to into banks. What a big time fail, France.

Sport was mandatory due to the military nature of the school. This did have the upside of getting students together more, although Ciro is against all forms of forced intellectual of physical activities for students. If you liked your sport it would be really cool though. But due to Section "Ciro Santilli's knee", he was forced to give up his first beloved choice which was soccer... life can be cruel. If only Ciro had known cycling at at the time, and if only that had been one of the sports you could choose (but of course it isn't, no school will want the bad reputation of when one of their students gets killed in a car accident).

There were also some useless "military exercises", or special situations in which you had to wear the useless school uniform as a formal "respect social clothing". Ciro Santilli is completely against all that meaningless bullshit, this his just a form of theatrical masturbation to nostalgically remember the good old days of Napoleon when France still ruled the world, and before they tortured the Algerians, see also: Video 4. "Gérard Fuchs interview from Ils racontent la Guerre d'Algérie (1982)". If you are going to do military-like stuff, then at least teach students how to shoot modern rifles and modern warfare tactics (which some of the French students actually do in the pre-school mandatory internship), and not this 18th century bullshit. Ciro favours of course the hoodie-wearing, "I only care about your abilities meritocracy" culture of Silicon Valley. And without the political correctness now associated with it in the 2020s. And no shooting people if possible.

During the time Ciro was at Polytechnique in early 2010's, the school was really isolated in the Plateau de Saclay, there were no shops in 10 minute walking distance! You either had to climb 300 steps to go down to the nearest village, Lozère, or take a bus to the nearest town, Massy. The fact that Times Higher Education ranked it as the second best university in the world in 2019 (archive) makes it good justice, given the small 500 student body. Things started to change a bit after Ciro left however, with the creation of the Polytechnic Institute of Paris, which is bringing other schools to the Lozere area. This is for the best, as it might improve the global rankings of Polytechnique. Also it is a waste to have so few students at a technopole. But it will reduce the mystique of the place. You can't have everything in life.

Before 1976, Polytechnique was actually in the center of Paris at the Latin Quarter, so the Lozère mystique is not a traditional thing. But even when in Paris, students were in theory restricted to school grounds a most of the time. Although there are famous stories of a certain tree that could be used to climb the fence to go to Parisian parties when they couldn't stand it anymore. The tree was somewhat intentionally overlooked by school administrators. Polytechnique was drawn to Saclay no doubt because of the gravity of the CEA Paris-Saclay, France's analog to the United States Department of Energy national laboratories.

This made for some good memories though. The isolation favored concentration, and gave the place a mystical feeling. And then when you went to eat amazing Chinese food in Paris it just felt even more special and magic since you were so limited during the week. It was also under those magical circumstances in which Ciro met his wife, another student of the school, see also: Section "The main function of university is sexual selection".

Ciro also agonized about passing courses to get useless grades though! Polytechnique is hard for most Brazilians, specially if you select the more mathematics oriented courses, because the French students were math brainwashed for two years before joining.

Ciro's favorite spots/activities:

The following promotional videos give an idea of how the school looks like, although they fundamentally miss the little corners that Ciro really loved in that the place and which made it magic:

Loudness compensation is a feature used in audio processing and playback systems to adjust the equalization of sound based on the perceived loudness at different volume levels. Human hearing does not respond equally across all frequencies at low and high loudness levels; we tend to hear bass and treble frequencies less prominently when listening at lower volumes. To counteract this, loudness compensation boosts certain frequency ranges to ensure that the audio remains balanced and pleasant to listen to, even at lower sound levels.

Low field magnetoresistance (LFMR) refers to the change in electrical resistance of a material when subjected to a weak external magnetic field. This phenomenon is often observed in certain types of materials, especially in ferromagnetic and semiconductor systems. ### Key Points: 1. **Definition**: LFMR involves a measurable change in resistance when exposed to a magnetic field that is relatively small compared to the magnetic fields usually involved in magnetoresistance studies.

As of my last update in October 2023, "Virokine" does not refer to a widely recognized term or a specific product in mainstream science or medicine. It's possible that it could be a term related to antiviral therapy, a novel biotechnology product, or a proprietary drug under development that has emerged after my last knowledge update.

\( L/poly \) is a complexity class in computational theory that represents languages (sets of strings) that can be decided by a logarithmic amount of working memory (specifically, space) with the help of polynomial-size advice strings. Here's a more detailed breakdown: 1. **Logarithmic Space** (\( L \)): This part signifies that the computation is done using an amount of space that grows logarithmically with the size of the input.
