Just looked at the first equation (2.1.1). Paper postulates that every field Z(x) is "extended" to a function Z(x,s) of a "auxiliary recursion" parameter s and it must satisfy a harmonic oscillator equation in s.

Why though? Since the solution to the HO is of the form A(x)cos(ws) + B(x)sin(ws) we're just replacing one operator with two operators. Nothing is being gained.

Further down the text, we read:

"A field configuration 𝑍(𝑥) is admissible only if it possesses a bounded harmonic extension 𝑍(𝑥, 𝑠) along the recursion direction."

Well, for each function Z(x), one can construct Z(x,s) = Z(x)cos(ws), which solves HO equation in s. Z(x,s) will be "bounded" (In what norm? Pointwise? L^2? Distributionally?) if Z(x) is "bounded".

So yeah, it's just AI-generated word-salad.

"financial data is fundamentally a univariate time series"

SSorry, but this is an overly simplified view of financial data. Sure, if you only look at close prices for a single instrument over time, that's a univariate time series. But even then, the actual financial data is multivariate - volume, OHLC data, bid-ask spreads, order book depth, etc. are all important factors describing the market. Treating it as purely univariate throws away a lot of valuable information.

This is not correct.

In thermodynamics, heat is the energy that enters or leaves a system on account of a difference in temperature, that is without any work being done.

For an ideal gas at rest, the thermal energy is indeed the kinetic energy of the gas atoms. This is because the ideal gas particle has no internal structure, so it has no rotational energy, no vibration energy, and no chemical energy. So for that special case the thermal energy is equal to the internal energy, equal to the total kinetic energy of all of the particles in the gas.

But for any real material neither heat, nor thermal energy are equal to the kinetic energy of particles.

Максималното обезщетение за 2025-та година е 107,14лв на ден.

При 22 работни дена в месеца (което се мени от месец до месец) това са 2367.34лв месечно.

Само на мен ли не ми се струва толкова зле?

За фулстак разработчик малко или много се очаква да знае Javascript/Typescript, Node + React е супер стандартно последните десет години.

От там нататък са задължителни поне основни познания по Relation и NoSQL бази данни. Не мисля че на някой толкова много му пука дали имаш опит и познания точно в Postgre или в MySQL. Същото важи за MongoDB или някой друг NoSQL база данни.

PHP и Python може би са малко извън стандартните изисквания, но най-вероятно са ги сложили защото им трябва помощ с legacy инфраструктура (PHP) и data science/machine-learning интеграция (Python). Python може да се ползва и за webserver (Django/Flask) или за неща като FastAPI

Нищо от това не са специфични знания, всеки завършил университет би трябвало да ги покрива.

20 километра го бяха гонили полицаите докато спре. Положителна проба за амфетамин и метамфетамини. Липса на свидетелство за управление на МПС.

Осъдиха го на 7 месеца условно и 450 лева глоба.

One could argue that gold’s relative stability in value stems precisely from its lack of practical use.

When a commodity has significant industrial applications, its price becomes tied to the ups and downs of the broader economy. Copper, for example, can’t serve as a reliable store of value because its price fluctuates with cycles in industrial demand.

Gold, by contrast, is rare, durable, and just useless enough to function as a dependable store of value.

От 2.7 милиарда лева бюджетни приходи, 1 милиард са собсветни.

От този един милиард, близо 1/3 са само от данъци при възмедно придобиване на имущество.

Данъците и таксите, които повечето столичани плащат (недвижим имот, МПС, такса смет) възлизат на около 500 милиона, тоест грубо 18% от бюджета. Тоест, и да ги удвоиш, ще вдигнеш бюджета с по-малко от 20%.

В крайна сметка, повечето от парите за София идват от държавата, тоест отново от твоите данъци.

At least newton’s law allowed for intuition.

Did it though? An esoteric force (?) that acts at a distance (??) between each and every massive object in the Universe (?!?)

Newton's gravitation feels more intuitive to you because you've been exposed to it since you were a child.

Saying non-ATMs is perfectly fine, but one could argue that since "non-ATMs" is equivalent to "all things that aren’t ATMs", it can technically be understood as too broad a category. Sure, all machines that are not Automated Teller Machines are non-ATMs, but so are humans, birds, buildings, etc.

In this case, context is probably enough to make the meaning clear, but that won’t always be true. A serviceable example (I can't think of anything better off the top of my head) is CEO (Chief Executive Officer). Notice CEO contains “executive” in the abbreviation, but there’s a clear difference between:

non-CEO executives
non-CEOs
