Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：The Proper Basis for Zero-dimensional Polynomial Ideals
零维 多项式理想 正确基 Grobner基
2023/11/23
The Grobner basis for a zero-dimensional polynomial ideal comprises a univariate polynomial in the least variable. The elimination process in Buchberger's algorithm unnecessarily involves the least va...
Podcast: Gender balance in nuclear, and the EU's Net Zero Industry Act

2023/4/1
An international survey has highlighted the need for a better gender balance in the nuclear sector, but how to achieve it? That's one of the issues discussed with Corhyn Parr, CEO of Nuclear Waste Ser...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Global and Local Convergence-Rate Analysis of an Inexact Newton Augmented Lagrangian Method for Zero-One Composite Optimization
零一复合优化 不精确 牛顿增强拉格朗日方法 收敛率分析
2023/3/24
Zero-One Composite Optimization (0/1-COP) is a prototype of nonsmooth, non- convex optimization problems and it has attracted much attention recently. Augmented Lagrangian Method (ALM) has stood out a...
The European Commission (EC) has proposed the Net-Zero Industry Act (NZIA) to scale up manufacturing of clean technologies in the EU and make sure it is well-equipped for the clean-energy transition. ...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Towards a zero-one law for improvements to Dirichlet's approximation theorem
Dirichlet近似定理 改进 零一定律
2022/11/17
In this talk we discuss a notion of $\psi$-Dirichlet in Diophantine approximation which concerns improving Dirichlet’s approximation theorem to a general approximating function $\psi$. This notion was...
April 27, 2007，British theoretical physicist Stephen Hawking – whose groundbreaking work on black holes and the origins of the universe has rewritten physics – floated free of his wheelchair in zero-g...
April 5, 2007,Using a laser-cooling technique that could one day allow scientists to observe quantum behavior in large objects, MIT researchers have cooled a coin-sized object to within one degree of ...
28 February 2007，A Loughborough University student has created a headline piece of art which will be used to symbolise Charnwood Borough Council’s Zero Waste Strategy.
