With recent requirements for reducing greenhouse gas emissions of autonomous ships, an emerging body of research is focused on assessing the path-following performance of maritime autonomous surface ships (MASS) at low speeds under adverse weather conditions. To combat the poor accuracy of traditional methods, in a new study, researchers investigated the path-following performance of MASS using a free-running computational fluid dynamics model. Their findings can help ensure safer autonomous navigation with

Девять чисел из научной статьи 2009 года сегодня работают у меня в четырёх местах: на HTML-странице, в canvas, в двух плагинах Figma и в чужом расширении для Chrome. Разбираю, как одна и та же матрица цветовосприятия ведёт себя в четырёх средах, где каждая среда сопротивляется по-своему — и почему честные ограничения инструмента важнее его возможностей.

Структура в роли ключа Dictionary — частый случай. Забыл IEquatable — и каждый TryGetValue в 4,4–5,7 раза медленнее, плюс 96 байт в куче на каждый поиск.Проверил на четырёх машинах и трёх рантаймах, снял дизасм FindValue и разобрал, откуда берутся ровно три упаковки, почему override Equals не спасает и при чём тут хэш record struct. Сам рантайм этот разрыв не закроет — и это не баг. Читать далее Read more ›

О событии Летом этого года в издательство НПК ПРАВДА поступила долгожданная рукопись книги автора Ворошилова В. В., завершающей серию рукописей «Основы единой физической теории». Нас, организаторов издательства, однокурсников, выпускников радиотехнического факультета Ленинградского института авиационного приборостроения 1985 года, со студенческой скамьи, удивляла и раздражала неполнота и противоречивость теоретической физики, особенно квантовая механика, лишенная физического смысла, по признанию самих ее.

Некоторое время назад появилась новость, что Сэм Альтман и Джонни Айв начали совместный проект. Тогда практически ничего не сообщалось о том, что именно они собираются делать. Говорилось лишь о том, что речь идет не о программном обеспечении, а о каком-то новом устройстве.И вот недавно появились подробности, что этим устройством станет нечто вроде умной колонки. Честно говоря, сначала это разочаровало. Рынок умных колонок уже давно существует. Есть Amazon Echo, Apple HomePod,... Read more ›

Honor launched the Power2 in January, and then, in May, we heard that the upcoming Power3 would have a battery capacity of 11,000 to 12,000 mAh, while the exact number wasn't decided yet. Today a new rumor from the same source is back to dial down our expectations, unfortunately. According to Digital Chat Station on Weibo, the Honor Power3 will have a battery of at least 10,000 mAh. The Power2... Read more ›

A 12-week intermittent fasting program produced weight-loss benefits that were still visible a year later. Participants who ate within an eight-hour window maintained more weight loss than those who followed their usual longer eating schedule. Both early and late eating windows worked, while early fasting appeared especially helpful for preserving fat loss. Read more ›

Seismic waves have revealed that the oceanic plate beneath the Ontong Java Plateau was dramatically transformed by the colossal volcanic activity that created it more than 100 million years ago. Researchers found a complex structure of horizontal layers cut through by vast swarms of vertical magma channels, along with unusually slow seismic waves suggesting that deep-rising magma chemically altered the plate itself.

A catastrophic asteroid breakup may have triggered a huge wave of impacts across the inner solar system about 800 million years ago. The debris was launched from near a gravitational gateway controlled by Jupiter, sending fragments toward Earth, the Moon, and Mars. The bombardment may explain ancient lunar craters and could have contributed to major climate and biological changes on Earth. Read more ›

Several popular sugar substitutes may not be as harmless as they seem. Adults who consumed the most artificial sweeteners showed substantially faster declines in memory and thinking, especially if they were under 60 or had diabetes. The highest intake was linked to cognitive aging roughly 1.6 years faster than the lowest intake. Researchers stressed that more studies are needed before concluding that sweeteners are the cause.

A low-cost antidepressant may offer new hope for people struggling with long COVID fatigue. In a randomized clinical trial involving 399 adults, fluvoxamine significantly reduced fatigue and improved quality of life compared with a placebo, making it one of the first medications to show meaningful benefits for this disabling condition.

The asteroid that wiped out the dinosaurs was likely an exceptionally rare CO chondrite from a distant region of the solar system. Its unusual chemistry suggests that planet-cooling dust and debris, rather than sulfur inside the asteroid, may have delivered the deadliest blow. Read more ›

Fossils from Queensland suggest a newly recognized marsupial order may have survived in Australia for around 35 million years, rewriting part of the story of how the continent's unique mammals evolved. The discovery challenges the idea that Australia's marsupials all came from a single straightforward ancestral lineage. Read more ›

Scientists may have uncovered one reason coffee is repeatedly associated with healthier aging and lower disease risk. Compounds in coffee appear to activate NR4A1, a receptor that helps protect cells from stress, inflammation, and damage. These protective effects disappeared when the receptor was removed, strengthening the connection. Surprisingly, plant-based compounds such as caffeic acid seemed far more active than caffeine itself.

The mysterious sound known as The Hum has been reported worldwide for decades, yet its source often remains impossible to find. Researchers tested whether people who hear it have exceptional low-frequency hearing or measurable sounds produced inside their ears, but neither explanation fit most participants. The strongest possibility is that many cases involve low-frequency tinnitus, even though the sound seems completely external. Read more ›

Researchers have created cosmic dust from scratch by recreating space-like conditions inside glass tubes. The dust contains complex carbon-rich molecules built from elements essential to life and produces infrared signals similar to real material found in space. By studying these laboratory samples, scientists can explore how organic chemistry unfolds around stars and how comets, asteroids and meteorites may have carried those ingredients to Earth.
