We consider the semiclassical limit from the Hartree equation with Coulomb interaction potential to the Vlasov–Poisson equation. Using a new stability estimate for the difference of the square roots o...
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
2023/4/14
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...

Accompanying China's rapid urbanization in recent decades, especially in the new millennium, the housing problem has become one of the most important issues. The estimation and analysis of housing vac...
Ecology team finds leaf litter has slower decomposition rate in warm temperatures than previously estimated
Ecology team leaf litter slower decomposition rate warm temperatures previously estimated
2017/7/19
The time it takes for a leaf to decompose might be the key to understanding how temperature affects ecosystems, according to Kansas State University ecologists. Using leaf litter data in streams from ...
Using the Loess Method to Describe the Effect of Temperature on Development Rate
non-parametric model local regression weighted least squares Aphididae
2018/3/5
Temperature has a significant influence on development rates of insects and mites. Many parametric models were
built to describe the temperature-dependent development rates. However, these models pro...

Antarctic Bottom Waters Freshening at Unexpected Rate
Antarctic Bottom Waters Freshening Unexpected Rate
2017/2/16
In the cold depths along the sea floor, Antarctic Bottom Waters are part of a global circulatory system, supplying oxygen-, carbon- and nutrient-rich waters to the world’s oceans. Over the last decade...
Does basal metabolic rate predict weight gain?
body composition body-weight change clinical research energy expenditure free-living adults indirect calorimetry longitudinal follow-up
2018/12/14
Background: Some previous studies have indicated that a low basal metabolic rate (BMR) is an independent predictor of future weight gain, but low rates of follow-up and highly select populations may l...
