Particle-type dependence of azimuthal anisotropy and nuclearmodification of particle production in Au+Au collisions at sNN = 200GeV (open access)

Particle-type dependence of azimuthal anisotropy and nuclearmodification of particle production in Au+Au collisions at sNN = 200GeV

We present STAR measurements of the azimuthal anisotropy parameter v{sub 2} and the binary-collision scaled centrality ratio R{sub CP} for kaons and lambdas ({Lambda} + {bar {Lambda}}) at mid-rapidity in Au+Au collisions at {radical}s{sub NN} = 200 GeV. In combination, the v{sub 2} and R{sub CP} particle-type dependencies contradict expectations from partonic energy loss followed by standard fragmentation in vacuum. We establish p{sub T} {approx} 5 GeV/c as the value where the centrality dependent baryon enhancement ends. The K{sub S}{sup 0} and {Lambda} + {bar {Lambda}} v{sub 2} values are consistent with expectations of constituent-quark-number scaling from models of hadron formation by parton coalescence or recombination.

Enron: A Select Chronology of Congressional, Corporate, and Government Activities

This report presents basic background information on the collapse of the Enron Corporation, identifying public policy issues in financial market oversight. This report briefly summarizes some federal laws carrying criminal penalties which may be implicated in the events surrounding the collapse of the Enron Corp. This report compares the auditing and accounting reform measures passed by the House (H.R. 3763) and reported by the Senate Committee on Banking, Housing, and Urban Affairs. This report compares the major provisions of three auditor and accounting reform proposals: H.R. 3763, S. 2673, and a rule proposed on June 20, 2002, by the SEC that would create a new auditor oversight board by using the SEC’s existing authority to regulate corporate accounting. The report focuses on Section 404(a) of the Employee Retirement Income Security Act (ERISA), the federal statute that regulates employer-sponsored pension plans. Section 404(a) is considered the “touchstone for understanding the scope and object of an ERISA fiduciary’s duties.”

Simulation of a Spherical Wave Experiment in Marble using a Multidirectional Damage Model (open access)

Simulation of a Spherical Wave Experiment in Marble using a Multidirectional Damage Model

This paper presents experimental results and computational simulations of spherical wave propagation in Danby marble. The experiment consisted of a 2-cm-diameter explosive charge detonated in the center of a cylindrical rock sample. Radial particle velocity histories were recorded at several concentric locations in the sample. An extensively damaged region near the charge cavity and two networks of cracks were evident in the specimen after the test. The first network consists of radial cracks emanating form the cavity and extending about halfway through the specimen. The second network consists of circumferential cracks occurring in a relatively narrow band that extends from the outer boundary of the radially cracked region toward the free surface. The experiment was simulated using the GEODYN code and a multi-directional damage model. The model is developed within the framework of a properly invariant nonlinear thermomechanical theory with damage represented by a second order tensor that admits load-induced anisotropy such as was observed in the experiment.
