Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Bubbling and extinction for some fast diffusion equations in bounded domains
有界域 快速扩散方程 气泡 消光
2023/11/13
Motivated by the Wisconsin octupole experiments on anomalous diffusion of hydrogen plasma across a purely poloidal octupole magnetic field, Berryman-Holland 1980 proved the stability of separable solu...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：The regularity with respect to domains of the additive eigenvalues of super-quadratic Hamilton-Jacobi equation

Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Strichartz estimates for wave equations with a potential in non-trapping exterior domains
斯特里查茨估计 非陷阱外域 波动方程
2023/4/14
Consider the linear wave equations with a potential outside a compact set with a non-trapping boundary condition. Assuming that the potential satisfies an appropriate decreasing condition and that zer...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Rigidity of non-compact static domains in hyperbolic space via positive mass theorems
正质量定理 双曲空间 非紧致 静域刚性
2023/4/14
We single out a notion of staticity which applies to any domain in hyperbolic space whose boundary is a non-compact totally umbilical hypersurface. For (time-symmetric) initial data sets modeled at in...
Uncovering process domains in large rivers: Patterns and potential drivers of benthic substrate heterogeneity in two North American riverscapes
rivers North American benthic
2021/7/23
Identifying and understanding functional process domains (sensu Montgomery, 1999) in rivers is paramount for linking the physical habitat template to ecosystem structure and function.

Cellular Division Strategy Shared All Domains Of Life
2018/1/10
The three domains of life — archaea, bacteria, and eukarya — may have more in common than previously thought.Over the past several years, Ariel Amir, Assistant Professor in Applied Mathematics at the ...
Bayesian seismic multi-scale inversion in complex Laplace mixed domains
Low-frequency Complex mixed-domain Laplace inversion Bayesian estimation Multi-scale inversion
2018/4/2
Seismic inversion performed in the time or frequency domain cannot always recover the long-wavelength background of subsurface parameters due to the lack of low-frequency seismic records. Since the lo...
Formation and Analysis of Topographical Domains Between Lipid Membranes Tethered by DNA Hybrids of Different Lengths
Cell Membrane DNA Membrane Lipids Lipid Bilayers 1,2-Dipalmitoylphosphatidylcholine Microscopy, Fluorescence Base Sequence Molecular Sequence Data Models,Chemical Unilamellar Liposomes
2016/5/25
We recently described a strategy to prepare DNA-tethered lipid membranes either to fixed DNA on a surface or to DNA displayed on a supported bilayer [Boxer et al., J. Struct. Biol., 2009, 168, 190; Bo...
A PROOF OF THE UNIFORMIZATION THEOREM FOR ARBITRARY PLANE DOMAINS
UNIFORMIZATION THEOREM ARBITRARY PLANE DOMAINS
2015/8/26
We present a simple constructive proof of the Uniformization Theorem which works for plane domains. The proof is a combination of covering space theory and Koebe's constructive proof of the Riemann ma...
Microbial life thrives in virtually every habitat imaginable in the ocean, from the scalding temperatures found at hydrothermal vents, to frigid environments in and under polar sea ice, to high-pressu...

Conversation of Intrinsic Disorder in Protein Domains and Families
disorder protein domains
2015/5/27
Protein regions which lack a fixed structure are called ‘disordered’. These intrinsically disordered regions are not only very common in many proteins, they are also crucial to the function of many pr...
