Уважаемые коллеги!

На заседании Ученого совета ИТФ в пятницу 31 мая в 11:30 будут заслушаны
2 доклада:

_1) Н.Г. Маснев_, Е.В. Подивилов, Б.И. Стурман
*Влияние проводимости доменной стенки на кинетику обращения
сегнетоэлектрического домена*

Недавнее открытие и исследование проводимости доменной стенки (ДС) в
сегнетоэлектриках обещает существенно модифицировать представление о
переполяризации. На примере ниобата лития показано, что наличие
проводимости ДС не только решает давнюю проблему нереалистично высокой
энергии образования доменов, но также приводит к экспоненциальным
зависимостям электрического поля exp(−E_n /E) и exp(−E_l /E) для
скоростей нуклеации (n) и латерального (l) роста с характерными полями
E_n ≈ 75 и E_l ≈ 15 кВ/мм. Кинетика изменения поляризации демонстрирует
различные стадии зарождения, латерального роста и слияния отдельных
доменов. В соответствии с экспериментом это соответствует общему
экспоненциальному закону exp(E^* ) для времени разворота с E_l < E^* <
E_n . Насколько нам известно, это исследование является первым,
объясняющим теоретически это закон.
Письма в ЖЭТФ, 119(10), 766-767 (2024)

2) А.О. Короткевич
*Прямой каскад турбулентности капиллярных волн: численное моделирование*
(короткий доклад)

Приводятся результаты большого массива экспериментов по моделированию
турбулентности капиллярных волн. Получен динамический диапазон прямого
каскада более одной декады в пространстве волновых векторов, что
соответствует примерно двум декадам по частоте. Рассматривается влияние
размера области на наблюдаемые спектры.

ID и пароль онлайн-трансляций в Zoom те же, что и для предыдущих
трансляций семинаров и докладов на Ученом совете:

Meeting ID: 968 9936 4518
Пароль: 250319

При числе желающих не менее 5 будет организован автобус.
Для записи на автобус из Москвы в Черноголовку необходимо до 18:00
четверга отправить письмо на адрес электронной почты bus@itp.ac.ru
После этого записавшимся до 20:00 поступит подтверждение об отправке или
неотправке автобуса в зависимости от числа записавшихся.
Запись на обратный автобус - на Ученом совете.

SpaceX launches Earth-observing satellite to orbit on 2nd leg of doubleheader (photos, video)

Chinese astronauts perform record-breaking spacewalk | Space Quiz! What role did Denise Crosby play in "Star Trek: The Next Generation"? | SpaceX launches Earth-observing satellite to orbit Created for znamenski.spacecom@blogger.com |  Web Version May 29, 2024 CONNECT WITH SPACE.COM       Something amazing every day. SIGN UP ⋅   WEBSITE   The Launchpad Chinese astronauts perform record-breaking spacewalk (CMSA) Two Chinese astronauts just set a new spacewalking record for the country. Ye Guangfu and Li Guangsu, two members of China's three-person Shenzhou 18 mission, spent about 8.5 hours working outside the Tiangong space station yesterday (May 28). That's longer than any previous Chinese spacewalk, or extravehicular activity (EVA), according to the nation's state-run Xinhua news service. Full Story: Space (5/28)  Space Quiz!

Beverly Crusher Deanna Troi Ro Laren Tasha Yar SpaceX launches Earth-observing satellite to orbit (ESA/SpaceX) A new Earth-observation mission made it to space yesterday (May 28). A Falcon 9 rocket from SpaceX lifted off with the Earth Cloud Aerosol and Radiation Explorer satellite, or EarthCARE for short, from Vandenberg Space Force Base in California today at 6:20 p.m. EDT (2220 GMT or 3:20 p.m. local time in California). It was the second launch of the day for SpaceX, which also sent a group of its Starlink internet satellites to orbit from Cape Canaveral Space Force Station in Florida this morning.

You'll be forgiven for immediately thinking of the best telescopes when it comes to astronomy but, even though they don't offer the same viewing power, binoculars can offer stunning night sky views for less. You might find that some top binoculars are more cost-effective, even if you were to bag one of the best telescope deals.

Colossal X-class solar flare suggests return of sunspot group that fueled May's epic auroras (video)

X-flare suggests return of sunspots from May's auroras | Space Quiz! How long does it take the sun to complete one full rotation? | This Week In Space podcast: Episode 112 - Mars on Pause? Created for znamenski.spacecom@blogger.com |  Web Version May 28, 2024 CONNECT WITH SPACE.COM       Something amazing every day. SIGN UP ⋅   WEBSITE ADVERTISEMENT The Launchpad X-flare suggests return of sunspots from May's auroras (NASA / SDO and the AIA, EVE, and HMI science teams / helioviewer.org) The colossal sunspot group AR3664 responsible for the epic May 2024 solar storms and widespread auroras is back - well, almost. Though sunspot group 3664 remains hidden from NASA's Solar Dynamics Observatory's view - scientists can track the sunspot's progress across the sun's far side by observing how it affects the sun's vibrations or seismic echoes, using helioseismology data.

(NASA) Starliner is still set to fly on its historic first flight with astronauts on June 1, but that could change as the team works through "complicated" issues following a small helium leak. NASA and Boeing officials emphasized they are carefully weighing the decision to launch Starliner's first test mission with astronauts to the International Space Station (ISS). The approximately one-week mission is known as Crew Flight Test (CFT) and includes NASA astronauts Butch Wilmore and Suni Williams, both former U.S. Navy test pilots.

"The Acolyte" and its 8-episode first season will roll out as a product of The High Republic era in the "Star Wars" timeline, a period of growing unrest when the fabled Jedi Knights reigned supreme some 100 years prior to the events of "Star Wars: The Phantom Menace" and the entire Skywalker Saga.
