Underground pedestrian systems (UPS) have been developed worldwide especially in the central areas of mega cities. They are integrated with subway systems, underground shopping streets and malls, and the basement of department stores in various forms and integrated with commerce, transport, retailing and public usage in urban functions. In cities with severe weather conditions such as Toronto a...

Plyometric research in the upper extremity is limited, with the effects of open-chain plyometric exercises being studied most. Kinematic and ground reaction force data concerning closed-chain upper extremity plyometrics has yet to be examined. Twenty-one recreationally active male subjects performed four variations of plyometric push-ups in a counterbalanced order. These included box drop push-...

Aggregation-prone proteins have been suggested to overwhelm and impair the ubiquitin/proteasome system (UPS) in polyglutamine (polyQ) disorders, such as Huntington's disease (HD). Overexpression of an N-terminal fragment of mutant huntingtin (N-mutHtt), an aggregation-prone polyQ protein responsible for HD, obstructs the UPS in cellular models. Furthermore, based on the accumulation of polyubiq...

Undifferentiated pleomorphic sarcoma (UPS) is the most common sarcoma that appears in older patients, usually in the extremities and the retroperitoneum. Other locations are rare. By definition, in UPS, although the malignant cells tend to appear fibroblastic or myofibroblastic, they should not show differentiation towards a more specific line of differentiation. In this sense, we report the ca...

InterMath participants spend time in workshops exploring technology-rich mathematical investigations and completing write-ups. These write-ups include a written explanation of their problem solving process, screen captures of files that they generated while completing the investigation and links to these files. This paper examines the use of graphical representations in write-ups that included ...

Uninterruptible power supplies (UPS) play an important role in interfacing critical loads such as computers, communication systems, medical/life support systems, and industrial controls to the utility power grid. Among the various UPS topologies, on-line UPS provides the most protection to such loads against any utility power problem. However, because of the multiple power conversion stages, on...

Ubiquitin-proteasome system (UPS) is a multistep protein degradation machinery implicated in many diseases. In the nervous system, UPS regulates remodeling and degradation of neuronal processes and is linked to Wallerian axonal degeneration, though the ubiquitin ligases that confer substrate specificity remain unknown. Having shown previously that class IV dendritic arborization (C4da) sensory ...

This study aims at empirically investigating whether technology incubators help academic high-tech start-ups to establish collaborations with other organizations, thus increasing the competitiveness of these firms. In doing so, we take into account the specificities of academic hightech start-ups with respect to their non-academic counterparts. We compare the effects of incubation on academic a...

Uninterruptible power supply (UPS) systems are required for supplying sinusoidal output voltage for linear and nonlinear loads. They must be highly reliable and fast in dynamic response. Many control strategies have been applied to UPS inverters. The basic objectives of UPS control systems are tracking ability and robustness. Generally, the tasks of output voltage control for UPS inverters are ...
