Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Two families of $n$-rectangle nonconforming finite elements for sixth-order elliptic equations
六阶椭圆方程 矩形 有限元族
2023/4/13
We propose two families of nonconforming finite elements on $n$-rectangle meshes of any dimension to solve the sixth-order elliptic equations. The unisolvent property and the approximation ability of ...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：The Rankin-Selberg problems in families
家庭 兰金-塞尔伯格问题 Hecke尖点形式
2023/5/9
Let $f$ be a holomorphic Hecke cusp form or Hecke-Maass cusp form for $SL(2,\mathbb{Z}),$ and let $\lambda_{f}(n)$ be the $n$th Hecke eigenvalue. Rankin and Selberg showed that$$\sum_{1 \leq m \leq X}...

MUMFORD-TATE GROUPS FAMILIES OF CALABI-YAU VARIETIES ANALOGUE ANDR E-OORT PROBLEMS I
2018/4/20
We study Mumford-Tate groups of families of Calabi-Yau manifolds in this notes, for example, we have interest in the relations between the geometry of families of Calabi-Yau manifolds and their Mumfor...

A grisly method by which bacteria dispatch their distant relatives also creates conditions in which the attackers can thrive.Families of bacteria cells are known to kill adjacent, unrelated cells by i...
Size–frequency distributions of fragments from SPH/N-body simulations of asteroid impacts: Comparison with observed asteroid families
Asteroids Collisional physics Impact processes
2015/12/25
We investigate the morphology of size–frequency distributions (SFDs) resulting from impacts into 100-km-diameter parent asteroids, represented by a suite of 161 SPH/N-body simulations conducted to stu...
Collisions and Gravitational Reaccumulation:Forming Asteroid Families and Satellites
Collisions and Gravitational Asteroid Families Satellites
2015/12/25
Numerical simulations of the collisional disruption of large asteroids show that although the parent body is totally shattered, subsequent gravitational reaccumulation leads to the formation of an ent...
Formation of Asteroid Families by Catastrophic Disruption:Simulations with Fragmentation and Gravitational Reaccumulation
asteroids dynamics planetesimals resonances surfaces asteroids
2015/12/25
This paper builds on preliminary work in which numerical simulations of the collisional disruption of large asteroids (represented by the Eunomia and Koronis family parent bodies) were performed and w...
Evolutionary Diversification of Multigene Families: Allelic Selection of Toxins in Predatory Cone Snails
Multigene Families Predatory Cone Snails
2015/12/17
In order to investigate the evolution of conotoxin multigene families among two closely related vermivorous Conus
species, we sequenced 104 four-loop conotoxin mRNAs from two individuals of Conus ebr...
DELIGNE PAIRINGS AND FAMILIES OF RANK ONE LOCAL SYSTEMS ON ALGEBRAIC CURVES
DELIGNE PAIRINGS LOCAL SYSTEMS ALGEBRAIC CURVES
2015/12/17
For smooth families of projective algebraic curves, we extend the notion of intersection pairing of metrized line bundles to a pairing on line bundles with flat relative connections. In this setting, ...
Compression schemes, stable definable families, and o-minimal structures
Compression schemes stable definable families o-minimal structures
2015/9/28
We show that any family of sets uniformly definable in an ominimal
structure has an extended compression scheme of size equal
to the number of parameters in the defining formula.

PARAMETER CHOICE MAPS WITH MANY CRITICAL POINTS
2015/9/25
We consider families of smooth one-dimensional maps with several critical points and outline the main ideas of the construction in the parameter space that allows to get infinite Markov Partitions and...

This paper characterizes mixtures of symmetric location families.
More specifically, let X = (XI, Xz, .. . ) be an exchangeable sequence of real-valued random
variables. By de Finetti's theorem, X...
Gibbs Sampling, Exponential Families and Orthogonal Polynomials
Family convergence rate gibbs sampler standard index
2015/7/8
We give families of examples where sharp rates of convergence to stationarity of the widely used Gibbs sampler are available. The examples involve standard exponential families and their conjugate pri...
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...
