Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Structure-Preserving Spectral Method for Large-Scale MHD System Simulation
MHD 系统仿真 保结构谱
2023/11/6
Structure-preserving numerical methods are crucial for achieving long-time accurate, stable, consistent and physically meaningful simulations. In this talk, we present H^1 and H(div) conforming spectr...
Maybe you can’t tell a book from its cover, but according to researchers at MIT you may now be able to do the equivalent for materials of all sorts, from an airplane part to a medical implant. Their n...
MIT engineers have designed a two-component system that can be injected into the body and help form blood clots at the sites of internal injury. These materials, which mimic the way that the body natu...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Futaki invariants and Yau’s conjecture on the Hull-Strominger system
Futaki invariants 丘成桐 赫尔-斯特罗明格系统 猜想
2023/4/23
In this talk, we will talk about Fernandez-Molina’s paper”Futaki invariants and Yau’s conjecture on the Hull-Strominger system”. We will introduce a new obstruction to the existence of solutions of th...
If you've ever played soccer with a robot, it's a familiar feeling. Sun glistens down on your face as the smell of grass permeates the air. You look around. A four-legged robot is hustling toward you,...
Engineers devise a modular system to produce efficient, scalable aquabots（图）

Underwater structures that can change their shapes dynamically, the way fish do, push through water much more efficiently than conventional rigid hulls. But constructing deformable devices that can ch...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：System Control Schemes based on Actor-Critic Learning Algorithms
Actor-Critic学习算法 系统 控制方案
2023/4/27
System optimization and control have become the key design philosophies in modern control system theories, where reinforcement learning (RL) algorithm has drawn considerable attention in recent litera...
Combustion engines, propellors, and hydraulic pumps are examples of fluidic devices — instruments that utilize fluids to perform certain functions, such as generating power or transporting water.
Cornell researchers have developed a fairer system for recommendations – from hotels to jobs to videos – so a few top hits don’t get all the exposure.
The internet had a collective feel-good moment with the introduction of DALL-E, an artificial intelligence-based image generator inspired by artist Salvador Dali and the lovable robot WALL-E that uses...
MIT engineers devise a recipe for improving any autonomous robotic system（图）
自主机器人系统 通用优化器 步行机器人 自动驾驶汽车
2023/6/20
Autonomous robots have come a long way since the fastidious Roomba. In recent years, artificially intelligent systems have been deployed in self-driving cars, last-mile food delivery, restaurant servi...
Artificial intelligence system learns concepts shared across video, audio, and text（图）

Sepsis claims the lives of nearly 270,000 people in the U.S. each year. The unpredictable medical condition can progress rapidly, leading to a swift drop in blood pressure, tissue damage, multiple org...
Let’s say you wanted to build the world’s best stair-climbing robot. You’d need to optimize for both the brain and the body, perhaps by giving the bot some high-tech legs and feet, coupled with a powe...
A universal system for decoding any type of data sent across a network（图）
解码 计算机网络 芯片 半导体技术
2023/6/9
Every piece of data that travels over the internet — from paragraphs in an email to 3D graphics in a virtual reality environment — can be altered by the noise it encounters along the way, such as elec...
