We prove that every rigid C*-bicategory with finite -dimensional centers (finitely decomposable horizontal units) can be realized as Connes' bimodules over finite direct sums of II_1 factors. In parti...

同余数问题是一个有着一千多年历史的数论问题,米尔诺群（K2群）是由著名数学家米尔诺于1970年代定义的新的代数结构，是代数K-理论中的研究课题。最近秦厚荣教授在国际上首次发现同余数和米尔诺群之间有着深刻的联系，并利用二次型在二者之间搭建了一个桥梁，展示了一个崭新的研究领域，并取得了重要的成果，相关论文于顶级数学刊物《Mathematische Annalen》在线发表。
A General Minimum Lower-Order Confounding Criterion for Two-Level Regular Designs
Clear effects criterion Estimation ability
font style='font-size:12px;'>
2015/3/18
Based on the hierarchical ordering principle of factorial effects in experimental
design, we propose an aliased effect-number pattern (AENP) as a criterion to judge
a two-level regular design; such ...
Multistage Evaluation of Measure ment Error in a Reliability Study

We introduce sequential testing procedures for the planning
and analysis of reliability studies to assess an exposure’s measurement error.
The designs allow repeated evaluation of reliability of the...

Joint analysis of longitudinal measurements and survival data has received much attention in recent
years. However, previous work has primarily focused on a single failure type for the event time. In...

2012/12/4
At CRYPTO 2008 Stam [8] conjectured that if an (m+s)- bit to s-bit compression function F makes r calls to a primitive f of n-bit input, then a collision for F can be obtained (with high probability) ...
Algebraic proofs over noncommutative formulas

We study possible formulations of algebraic propositional proof systems operating with noncommutative formulas. We observe that a simple formulation gives rise to systems at least as strong as Frege, ...

2011/7/6
1-D scalar conservation laws with convex flux and Markov initial data
are now known to yield a completely integrable Hamiltonian system. In
this article, we rederive the analogue of Loitsiansky’s in...

We concern with a special class of binary cellular automata, i.e., the so-called particle cellular automata (PCA) in the present paper. We first propose max-plus expressions to PCA of 4 neighbors.

We study the dependence of graded Betti numbers of monomial ideals on the characteristic of the
base field. The examples we describe include bipartite ideals, Stanley–Reisner ideals of vertex-decompo...
