ARCSC holds second workshop（图）
ARCSC 研讨会 先进反应堆
2024/1/31
The Advanced Reactor Codes and Standards Collaborative (ARCSC) held its second workshop on November 30, 2023, in Washington, D.C. The hybrid event had just over 200 participants, including representat...
The second unit of Belarus's first nuclear power plant has been connected to the power grid and delivered its first kilowatt-hours to the country's electricity system.
Members of a CERN board were recently targeted by so-called “CEO fraud”, following the same format as the incident that occurred at the end of 2020. CEO fraud is a social engineering method to extract...
The fresh fundraising round for the operating extension of Atucha I and construction of a second dry storage facility for used fuel at the nuclear power plant site received offers of USD93 million, 16...
Denison Mines Corp plans to carry out additional evaluation work following the completion of a conceptual study of the potential application of in-situ leach (ISL) mining methods at the Midwest projec...
CERN joins in the celebrations on 14 April involving scientists from more than 65 countries.
A joint special purpose vehicle - named PGE PAK Energia J?drowa SA - has now officially been formed by Polish companies ZE PAK and Polska Grupa Energetyczna (PGE) to implement the project to construct...
The Belarus Nuclear Power Plant's unit 2 has reached the minimum controllable power level with a self-sustaining controlled nuclear reaction.
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Monotonicity of the second Neumann eigenfunction in symmetry domain
对称域 第二个 诺依曼特征函数 单调性
2023/4/18
In 1974, Jeffrey Rauch proposed the hot spot conjecture for the second eigenfunctions of the Neumann eigenvalue problems. We will recall some of its development and related studies in recent years. We...
Bruce unit 3 has officially begun its Major Component Replacement (MCR) outage. The Candu unit was removed from service on 1 March and is scheduled to come back online in 2026.
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：On the preservation of second integrals by RK methods
RK方法 保存 第二积分
2023/4/25
One can elucidate integrability properties of ODEs by knowing the existence of second integrals. However, little is known about how they are preserved, if at all, under numerical methods. In this talk...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：A second order accurate, decoupled numerical scheme for magnetohydrodynamic equations
磁流体 动力学方程 二阶精确解 耦数值方案
2023/4/27
A temporally second-order accurate, fully discrete finite element method is proposed and analyzed for the magnetohydrodynamic (MHD) equations. A modified Crank-Nicolson method is used to discretize th...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Suspension Homotopy of 4-manifolds And the Second 2-local Cohomotopy Sets
4-流形 悬浮同伦 第二个 2-局部 同伦集合
2023/4/28
In this talk we study the homotopy type of the (double) suspension of an orientable, closed, connected 4-manifold M, whose integral homology can have 2-torsion. Moreover, the decomposition results are...
Since late 2021, Carol Anne Barsody, a master’s student in archaeology, has been working to unravel the mysterious origins of a mummified sacred ibis that has been stored at Cornell for nearly 100 yea...
Artificial intelligence (AI) plays an important role in many systems, from predictive text to medical diagnoses. Inspired by the human brain, many AI systems are implemented based on artificial neural...
