Of the 23.8 million military veterans living in the United States, approximately 3 million have served in Operation Enduring Freedom or Operation Iraqi Freedom. The injuries and illnesses that affect veterans returning from combat are predictable. Blast injuries are common and most often present as mild traumatic brain injury, which is synonymous with concussion. Family physicians caring for re...

Traditionally, the goal of image segmentation has been to produce a single partition of an image. This partition is compared to some \ground truth," or human approved partition, to evaluate the performance of the algorithm. This paper utilizes a framework for considering a range of possible partitions of the image to compute a probability distribution on the space of possible partitions of the ...

Two field experiments were conducted for two years with the aim of studying the effects of deep tillage and straw returning on soil microorganism and enzyme activity in clay and loam soil. Three treatments, (1) conventional tillage (CT), shallow tillage and straw returning; (2) deep tillage (DT), deep tillage and straw returning; and (3) deep tillage with no straw returning (DNT), were carried ...

This issue of Cognitive Science marks the start of our partnership with Lawrence Erlbaum Associates (LEA). The journal has never been published by LEA before, but in many ways, our relocation feels like a homecoming. In 1976 Roger Schank approached Larry Erlbaum with the idea of forming a cognitive science journal. Mr. Erlbaum was highly receptive, and together with his partner Walter Johnson b...

Chudnovsky et al. gave a min-max formula for the maximum number of node-disjoint non-zero A-paths in group-labeled graphs [1], which is a generalization of Mader’s theorem on node-disjoint A-paths [3]. Here we present a further generalization with a shorter proof. The main feature of Theorem 2.1 is that parity is “hidden” inside ν̂, which is given by an oracle for non-bipartite matching.

The objective of this study was to determine whether kinematic data collected by the Microsoft Kinect 2 (MK2) could be used to quantify postural stability in healthy subjects. Twelve subjects were recruited for the project, and were instructed to perform a sequence of simple postural stability tasks. The movement sequence was performed as subjects were seated on top of a force platform, and the...

1. Force changes in areflexive cat soleus muscle in decerebrate cats were recorded in response to two sequential constant velocity (ramp) stretches, separated by a variable time interval during which the length was held constant. Initial (i.e., prestretch) background force was generated by activating the crossed-extension reflex, and stretch reflexes were eliminated by section of ipsilateral do...

Since the early 1990s, the town of Mandeville has become a haven for returning residents (henceforth returnees), particularly Jamaicans who migrated to England in the 1950s and 1960s and subsequently returned to Jamaica in the 1990s to retire (See Nettleford 1998). As Harry Goulbourne (1999, 164) observes, “...The hill town of Mandeville has acquired the reputation of being a desirous destinati...

Intussusception is invagination of one portion of intestine into the adjacent portion usually the proximal into the distal. It consists of three layers of gut. The receiving layer is called the intussuscipiens, the entering and the returning layers together are called the intussusceptum. Apex is the junction of the entering and the returning layers and is usually a fixed portion of the gut. Nec...
