Authorization and account management in the Open Science Grid
An attribute-based authorization infrastructure developed for the Open Science Grid is presented and an experimental PRIMA authorization service that extends and simplifies the infrastructure is described.
EPICS V4 EXPANDS SUPPORT TO PHYSICS APPLICATION, DATA ACSUISITION, AND DATA ANALYSIS*
The goal of this work is to define a narrow interface with the minimal set of data types needed to support a distributed architecture for physics applications, data acquisition, and data analysis.
Four Postulates of Quantum Mechanics Are Three.
A natural definition of a composite system as a set containing the component systems is given and how one can logically derive the tensor product rule from the state postulate and from the measurement postulate is shown.
A Scalable Grid User Management System for Large Virtual Organization
Updated core libraries of the ALPS project
Building the SLATE Platform
The high level goal of SLATE is to facilitate creation of multi-institutional science computing systems by augmenting the canonical Science DMZ pattern with a generic, "programmable", secure and trusted underlayment platform.
From physical assumptions to classical and quantum Hamiltonian and Lagrangian particle mechanics
The aim of this work is to show that particle mechanics, both classical and quantum, Hamiltonian and Lagrangian, can be derived from few simple physical assumptions. Assuming deterministic and…
Topology and Experimental Distinguishability
In this work we introduce the idea that the primary application of topology in experimental sciences is to keep track of what can be distinguished through experimentation. This link provides…

It is shown that the Shannon entropy can be fully understood as measuring the variability of the elements within a given distribution: it characterizes how much variation can be found within a collection of objects.
