Low back disorders (LBDs) are the most common and costly occupationally-related compensable conditions facing employers today. Over the years several biomechanical assessment models have been developed that intended to assess the load profile imposed upon the spine during lifting and, thus, intended to facilitate the control of LBD risk in the workplace. Many of these biomechanical models have ...

An algorithm and a robust floating point implementation is given for rotational polygon containment: given polygons P1,P2,P3, . . . ,Pk and a container polygon C, find rotations and translations for the k polygons that place them into the container without overlapping. A version of the algorithm and implementation also solves rotational minimum enclosure: given a class C of container polygons, ...

Broadcast digital subscriber lines (BDSL) can provide a cost-effective architecture to deploy digital broadcast services in the near future by utilizing the in-place unshielded twisted-pairs. In the BDSL system, all broadcasting channels can share the same transmitter to reduce the cost. Because all twisted-pairs transmit the same BDSL signal in the downstream direction, both nearand far-end cr...

Title: A preliminary evaluation of influence of body mass index on in vitro fertilization outcome in non-obese endometriosis patients.

Around 1 year of age, infants develop the ability to individuate objects in the absence of spatiotemporal information. Some have proposed that this capacity relies on the emergence of language and, in particular, that comprehending an object’s label is required to individuate it as a particular kind. One approach to testing this hypothesis is to conduct experiments on pre-linguistic human infan...

Objective: This prospective randomized study aims at evaluation and comparison of the prophylactic effects of amiodarone versus digoxin and metoprolol combination in postcoronary bypass atrial fibrillation. Methods: A total of 241 consecutive patients undergoing elective coronary artery bypass grafting were randomly allocated into three groups. Patients in Group1 (n 1⁄4 77) received metoprolol ...

In the late seventies and early eighties, multi-agent systems (MASs) emerged as a scientific area from several previous research domains, such as the distributed artificial intelhgence, intelligent robotics, and knowledge-based Systems. This area of research is now reaching a level cf maturity, enough for MAS to be applied as a technology for solving problems in complex applications. Using MAS ...

A contingency model is advanced that examines sources of requirements for organizational coordination and control as they affect the extent of integration in an accounting information system. Requirements that are contingent on the degree of organizational formalization, information interdependence among functional areas, and dependence in interorganizational information sharing and electronic ...

Chromatic induction from a surrounding light is measured with an additional remote field outside the surround. Chromatic induction from the surround into a central test field is found to be attenuated by a remote inhomogeneous ‘checkerboard’, composed of squares at two different chromaticities. A uniform remote field, on the other hand, either at the average or at the most extreme chromaticity ...

Immobilization stress decreases the expression of BDNF mRNA in the rat hippocampus, and this effect could contribute to the atrophy of hippocampal neurons. This study examines the influence of selective 5-HT, as well as norepinephrine, receptor antagonists on the stress-induced down-regulation of BDNF mRNA. Pretreatment with a selective 5-HT2A receptor antagonist, MDL100,907, significantly bloc...
