Removing the Graduate Record Examination as an Admissions Requirement Does Not Impact Student Success.

The predictive validity of components of the Graduate Record Examination (GRE) on student success is inconsistent, and the test itself has been shown to be a barrier for prospective students historically underrepresented in graduate programs. We analyzed three admissions cycles for the Master of Public Health degree at the Boston University School of Public Health before (2016, 2017, 2018) and after (2019, 2020, 2021) eliminating the GRE for diversity and quality of applications, student success, and employment outcomes. We observed increases in diversity (e.

Comparison of a Material Point Method and a Galerkin Meshfree Method for the Simulation of Cohesive-Frictional Materials.

The simulation of large deformation problems, involving complex history-dependent constitutive laws, is of paramount importance in several engineering fields. Particular attention has to be paid to the choice of a suitable numerical technique such that reliable results can be obtained. In this paper, a Material Point Method (MPM) and a Galerkin Meshfree Method (GMM) are presented and verified against classical benchmarks in solid mechanics.

Venous allografts preserved at 4 degrees C for infrainguinal bypass: long-term results from 170 procedures.

From April 21, 1982 to December 31, 1997, we performed 170 infrainguinal bypass procedures using isolated (n = 35) or composite (n = 135) venous allografts preserved at 4 degrees C as a substitute for saphenous autografts in 146 patients. The mean age of the patient population was 74 years. The indication was critical lower limb ischemia in 71% of cases.

Intracellular ice formation is affected by cell interactions.

Cell-to-cell and cell-to-surface interactions are important to the structure and function of tissues. These interactions are also important determinants of low-temperature responses in tissues. Four in vitro models using hamster fibroblast cells in tissue culture were used to investigate the influence of cell-cell and cell-surface interactions on intracellular ice formation in these systems.

Comparison of different techniques of hypothermic pig heart preservation.

The aim of this study was to compare several methods of hypothermic heart preservation. Isolated pig hearts were preserved for 24 hours in cold cardioplegic solution (St. Thomas' Hospital modified solution) by continuous perfusion (group I), microperfusion (group II), or simple storage (group III).
