Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Real-time tool path planning using deep learning for subtractive manufacturing
深度学习 减材制造 实时刀具 路径规划
2023/4/25
Tool path planning is a crucial factor of computer-aided design and manufacturing (CAD/CAM). To generate suitable tool paths, the previous methods often transform the problem into local or global opti...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Quasi-invariant theorem on the Gaussian path space
高斯路径 空间 准不变定理
2023/4/27
In this talk, we will first introduce a class of Gaussian processes, and prove the quasi-invariant theorem with respect to the Gaussian Wiener measure, which is the law of the associated Gaussian proc...
300-million-year-old fish resembles a sturgeon but took a different evolutionary path（图）
300-million-year-old resembles sturgeon different evolutionary path
2020/7/3
Sturgeon, long-lived, bottom-dwelling fish, are often described as living fossils. Their form has remained relatively constant, despite hundreds of millions of years of evolution.In a National Sc...
Chemists find path to 'new blue' in meteorite minerals（图）
Chemists path new blue meteorite minerals
2020/1/4
Scientist Mas Subramanian of Oregon State University, who made history a decade ago with the accidental discovery of the first new blue inorganic pigment in more than two centuries, is again pushing f...
When a chemical spills, it's important to know how quickly the spill will spread. When irrigating a crop, a farmer needs to know how fast water moves through soil for absorption by roots. In both case...
A probe invented at Rice University that lights up when it binds to a misfolded amyloid beta peptide — the kind suspected of causing Alzheimer’s disease — has identified a specific binding site on the...

Rules of Life outlines path predicting phenotype
2017/9/4
Imagine a world where scientists can predict with confidence whether crops will grow in extreme temperatures, just by understanding their genetic makeup. Consider a future where doctors can know what ...
Solar eclipse science along the path of totality:Eclipse on August 21 offers unique research opportunities
Solar eclipse science Eclipse August 21 unique research opportunities
2017/7/25
In a briefing today on solar eclipse science, leading U.S. scientists highlighted research projects that will take place across the country during the upcoming August 21 solar eclipse. The research wi...
Group blazes path to efficient,eco-friendly deep-ultraviolet LED
Group eco-friendly deep-ultraviolet LED
2017/3/14
The darkest form of ultraviolet light, known as UV-C, is unique because of its reputation as a killer – of harmful organisms.With wavelengths of between 200 and 280 nanometers, this particular form of...
Scientists develop genetic path to tastier tomatoes
Scientists genetic path tastier tomatoes
2017/2/16
Some consumers crave tastier tomatoes than those available at the supermarket. Now, scientists at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) and their partners hav...
“Wouldn’t it be interesting if we could create stained-glass windows that changed colors at the flip of a switch?” said Christy Landes, associate professor of chemistry at Rice and the lead researcher...
A path model for geodesics in Euclidean buildings and its applications to representation theory
path model for geodesics Euclidean buildings representation theory
2015/10/14
In this paper we give a combinatorial characterization of projections ofgeodesics in Euclidean buildings to Weyl chambers. We apply these results to the representation theory of complex reductive Lie ...
Months of warning signs from Mauna Loa, on Hawaii’s Big Island, prompted the U.S. Geological Survey to recently start releasing weekly updates on activity at the world’s largest active volca...
In other words where is the boundary between truly random and
almost deterministic behavior? I believe that very little randomness
is needed. For example consider the following model. Let f1 : : : f...
