Eastern Connecticut State University is a public, coeducational liberal arts university and a member of the Council of Public Liberal Arts Colleges. Founded in 1889, it is the second-oldest campus in the Connecticut State University System and third-oldest public university in the state. Eastern is located on Windham Street in Willimantic, Connecticut, on 182 acres 30 minutes from Hartford, lying midway between New York City and Boston. Although the majority of courses are held on the main campus, select classes take place at Manchester Community College, Capital Community College, and a satellite center in Groton.Eastern Connecticut State University is a member of the Connecticut State Colleges and Universities, with governance provided by the Connecticut Board of Regents for Higher Education.The university is ranked #108 for regional universities in the north in the 2014 edition of the U.S. News and World Report List of Best Colleges. Eastern is also one of 225 institutions that the Princeton Review lists as "Best Regional College" in the northeast.The president of Eastern is Dr. Elsa Nuñez. Wikipedia.

There are two distinct forms of urothelial (bladder) cancer: muscle-invasive (MI) and nonmuscle invasive (NMI) disease. Since it is currently believed that bladder cancer arises by transformation of urothelial cells of the basal layer, bladder cancer stem cells (CSCs) have been isolated based on expression markers found in such cells. However, these CSCs have only been identified in MI tumors raising the intriguing hypothesis that NMI tumor progenitors do not arise from the basal compartment. To test this hypothesis, we carried out genome-wide expression profiling of laser capture microdissected basal and umbrella cells, the two most histologically distinct cell types in normal urothelium and developed a cell of origin (COO) gene signature that distinguishes these. The COO signature was a better predictor of stage and survival than other bladder, generic, or breast CSC signatures and bladder cell differentiation markers in multiple patient cohorts. To assess whether NMI and MI tumors arise from a distinct progenitor cell (DPC) or common progenitor cell, we developed a novel statistical framework that predicts COO score as a function of known genetic alterations (TP53, HRAS, KDM6A, and FGFR3) that drive either MI or NMI bladder cancer and compared this to the observed COO score of the tumor. Analysis of 874 patients in five cohorts established the DPC model as the best fit to the available data. This observation supports distinct progenitor cells in NMI and MI tumors and provides a paradigm shift in our understanding of bladder cancer biology that has significant diagnostic and therapeutic implications. © 2013 AlphaMed Press.

A new approach is presented for the problem of planar optimal impulsive rendezvous of a spacecraft in an inertial frame near a circular orbit in a Newtonian gravitational field. The total characteristic velocity to be minimized is replaced by a related characteristic-value function and this related optimization problem can be solved in closed form. The solution of this problem is shown to approach the solution of the original problem in the limit as the boundary conditions approach those of a circular orbit. Using a form of primer-vector theory the problem is formulated in a way that leads to relatively easy calculation of the optimal velocity increments. A certain vector that can easily be calculated from the boundary conditions determines the number of impulses required for solution of the optimization problem and also is useful in the computation of these velocity increments. Necessary and sufficient conditions for boundary conditions to require exactly three nonsingular non-degenerate impulses for solution of the related optimal rendezvous problem, and a means of calculating these velocity increments are presented. A simple example of a three-impulse rendezvous problem is solved and the resulting trajectory is depicted. Optimal non-degenerate nonsingular two-impulse rendezvous for the related problem is found to consist of four categories of solutions depending on the four ways the primer vector locus intersects the unit circle. Necessary and sufficient conditions for each category of solutions are presented. The region of the boundary values that admit each category of solutions of the related problem are found, and in each case a closed-form solution of the optimal velocity increments is presented. Similar results are presented for the simpler optimal rendezvous that require only one-impulse. For brevity degenerate and singular solutions are not discussed in detail, but should be presented in a following study. Although this approach is thought to provide simpler computations than existing methods, its main contribution may be in establishing a new approach to the more general problem. © 2012 Springer Science+Business Media B.V. 2012.

This paper presents a review of the Quaternary-Recent deformation field and mountain building processes within the Gobi Corridor region of Central Asia, which includes the North Tibetan foreland, Beishan, Gobi Altai and easternmost Tien Shan. The region can be considered the 'soft core' of Central Asia which has been reactivated due to the continuing Indo-Eurasia collision to the south. Favourable preconditions for reactivation of Gobi Corridor basement include a mechanically weak Palaeozoic terrane collage sandwiched between rigid Precambrian basement blocks to the north and south, thermally weakened crust due to Jurassic-Miocene volcanism and widespread Palaeozoic-Mesozoic granitic magmatism with associated high radiogenic heat production, and crustal thinning due to widespread Cretaceous rift basin development. The network of Quaternary-Recent faults within the entire region defines a diffuse sinistral transpressional deformation field that has generated a transpressional basin and range physiographic province. Typically, thrust and oblique-slip thrust faults are WNW-striking and reactivate basement faults and fabrics, whereas left-lateral strike-slip faults are ENE-striking and cut across basement trends. The angular relationship between SHmax and pre-existing basement structural trends is the fundamental control on the kinematics of Late Cenozoic deformation. Along-strike and across-strike growth and coalescence of restraining bends, other transpressional ranges and thrust ridges is an important mountain building process. Thrust faults throughout the region are both NNE and SSW directed and thus there is no common structural vergence, nor orogenic foreland or hinterland. Root structures appear to be vertical faults, not low-angle decollements and flower structure fault geometries within individual ranges are common. Published earthquake and geodetic data are consistent with a diffusely deforming continental interior region with tectonic loading shared amongst a complex network of faults. Therefore, earthquake prediction is likely to be more complex than in plate boundary settings and extrapolation of derived Late Quaternary fault slip rates is not straightforward. Modern mountain building within the Gobi Corridor demonstrates that reactivation of ancient accretionary and collisional orogens within continental interiors can play an important role in continental evolution and the life cycle of orogenic belts. © 2012 Elsevier Ltd.

Many types of eukaryotic cells can fuse together as part of their normal developmental program or life cycle. This review describes a diverse set of examples of such cell types and focuses attention on several molecules that appear intimately involved in the process of plasma membrane merger that lies at the crux of every cell-fusion event. Some of these examples come from experimental systems where the discovery of molecules essential for cell fusion is sped by the approachability of the experimental organism itself. In other cases, especially in the many fusing human cell types, the molecular players in cell-cell membrane fusion are still to be discovered. © 2011 Elsevier Inc. Source

This paper presents several procedures for scheduling identical parallel machines with family setups when the objective is to minimize total tardiness. These procedures are tested on several problem sets with varying numbers of families, jobs and machines, varying setup time distributions and various levels of due date tightness and variability. The results show that genetic algorithms are the most effective algorithms for the problem. © 2014 Elsevier Ltd. All rights reserved. Source
