Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Linear reciprocal transformations of bihamiltonian integrable hierarchies
双哈密尔顿 可积层次 线性互易变换 流体力学
2023/11/13
For an integrable hierarchy which possesses a bihamiltonian structure with semisimple hydrodynamic limit, we prove that the linear reciprocal transformation with respect to any of its symmetry transfo...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Rational solutions of KP and BKP hierarchies through Toda lattice
户田晶格 KP BKP 层次结构 合理解
2023/4/27
The full Kostant-Toda lattice defined on simple Lie algebras can be viewed as finite version of KP type hierarchies. In this talk I will show you how to explicitly construct (all) rational solutions o...
Compilation for Explicitly Managed Memory Hierarchies
Software-managed memory hierarchy bulk operations
2016/5/24
We present a compiler for machines with an explicitly managed memory hierarchy and suggest that a primary role of any compiler for such architectures is to manipulate and schedule a hierarchy of bulk ...
A Portable Runtime Interface For Multi-Level Memory Hierarchies
Memory Hierarchies Parallelism Runtime Sequoia
2016/5/24
We present a platform independent runtime interface for moving data and computation through parallel machines with multi-level memory hierarchies. We show that this interface can be used as a compiler...
Achieving good performance on a modern machine with a multi-level memory hierarchy, and in particular on a machine with software-managed memories, requires precise tuning of programs to the machine’s ...
KINETIC HIERARCHIES AND MACROSCOPIC LIMITS FOR CRYSTALLINE STEPS IN 1+1 DIMENSIONS
kinetic theory epitaxial growth crystal surface Burton–Cabrera–Frank model particle system Bogoliubov–Born–Green–Kirkwood–Yvon hierarchy closure evaporation-condensation surface diffusion correlation function step chemical potential macroscopic limit propagation of chaos
2015/10/16
We apply methods of kinetic theory to study the passage from particle systems to nonlinear partial differential equations (PDEs) in the context of deterministic crystal surface relaxation. Starting wi...

The Flattening Firm:Evidence from Panel Data on the Changing Nature of Corporate Hierarchies
Geographic Location Change Business Ventures Compensation and Benefits Rank and Position
2015/5/14
Using a detailed database of managerial job descriptions, reporting relationships, and compensation structures in over 300 large U.S. firms, we find that firm hierarchies are becoming flatter. The num...
Social Comparisons and Deception Across Workplace Hierarchies:Field and Experimental Evidence
Behavior Rank and Position Employees
2015/5/13
We examine how unfavorable social comparisons differentially spur employees of varying hierarchical levels to engage in deception. Drawing on literatures in social psychology and workplace self-esteem...

The Flattening Firm and Product Market Competition:The Effect of Trade Liberalization on Corporate Hierarchies
Trade Managerial Roles Organizational Change and Adaptation Organizational Design
2015/5/12
This paper establishes a causal effect of product market competition on various characteristics of organizational design. Using a unique panel-dataset on firm hierarchies of large U.S. firms (1986-199...

The standardisation of mineral group hierarchies: application to recent nomenclature proposals
mineral group supergroup nomenclature mineral classification IMA朇NMNC
2013/12/6
A simplified definition of a mineral group is given on the basis of structural and compositional aspects. Then a hierarchical scheme for group nomenclature and mineral classification is introduced and...
