Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Tracing the Evolution of SMBHs and Stellar Objects in Galaxy Mergers: A Multi-mass Direct N-body Model
星系合并 SMBH 恒星物体演化 多质量 直接N体模型
2023/11/13
By using direct N-body numerical simulations, we model the dynamical coevolution of two supermassive black holes (SMBHs) and the surrounding stars in merging galaxies. In order to investigate how diff...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Existence of hyperbolic motions for Newtonian and generalized N-body problem（II）
牛顿 广义N体问题 双曲运动 存在性
2023/11/7
For the classical N-body problem, Maderna-Venturelli [Ann. Math. 2020] proved the existence of hyperbolic motions with any positive energy constant, starting from any configuration and along any nonco...
Many of our body’s most important functions occur without our conscious knowledge, such as digestion, heartbeat, and breathing. These vital functions depend on the signals generated by the “interocept...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars： Derivation of the Vlasov equation from quantum many-body Fermionic systems with singular interaction
奇异相互作用 量子多体 费米子系统 弗拉索夫方程
2023/5/12
We consider the combined mean-field and semiclassical limit for a system of the N fermions interacting through singular potentials. We prove the uniformly in the Planck constant h propagation of quant...

Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Many-body localization and quantum many-body scars: The strong and weak form of ergodicity breaking
多体定位 量子多体疤痕 遍历性断裂 强弱形式
2023/4/23
The fate of an isolated quantum many-body system has attracted much attention in the past decade. One of the most important issues is whether such a system can reach thermalization under its own dynam...
Using a miniature camera and a customized deep neural network, Cornell researchers have developed a first-of-its-kind wristband that tracks the entire body posture in 3D.
Ultrasound imaging is a safe and noninvasive window into the body’s workings, providing clinicians with live images of a patient’s internal organs. To capture these images, trained technicians manipul...
Ultrathin fuel cell uses the body’s own sugar to generate electricity（图）
超薄燃料电池 葡萄糖动力源 微型植入物 传感器
2023/6/7
Glucose is the sugar we absorb from the foods we eat. It is the fuel that powers every cell in our bodies. Could glucose also power tomorrow’s medical implants?
Electrodes that flow to fit the body（图）
流动 水凝胶电极 凝胶状琼脂糖
2023/6/21
Arrays of metal electrodes are often used in medical procedures that require monitoring or delivering electrical impulses in the body, such as brain surgery and epilepsy mapping. However, the metal an...

2007/4/9
5 April 2007,Scientists have discovered a sequence of canine DNA key to the great diversity in the body size of dogs, from Chihuahuas to Grant Danes, according to research in the 6 April issue of Scie...
April 2, 2007,University of Rochester researchers announce in the current issue of Applied Optics a technique that in 60 seconds or less measures multiple chemicals in body fluids, using a laser, whit...
Blame Our Evolutionary Risk of Cancer on Our Body Mass
Cancer Body Mass cellular lifespan
2006/12/19
December 6, 2006，A key enzyme that cuts short our cellular lifespan in an effort to thwart cancer has now been linked to body mass.
December 7, 2006，Leaded crystal and common glass may look similar, but the crystal is made of a rigid scaffolding of atoms, while the glass is a disordered, atomic slurry.Researchers at the University...
