A segment of DNA located between 131 and 311 base pairs (bp) upstream from the transcriptional start of the Myxococcus xanthus ops gene (-131 to -311) was shown to function as an upstream activation site (UAS) for developmentally regulated transcription from the tps gene promoter region. The activation of early developmental transcription by the ops UAS was independent of orientation and could ...

The phloem is a vascular strand that conducts photoassimilates and systemic signals throughout the plant to coordinate growth. To date, few molecular genetic determinants have been identified to control both specification and differentiation of this tissue [1-3]. Among them, OCTOPUS (OPS) protein was previously identified as a polarly localized plasma membrane-associated protein of unknown bioc...

In this paper we describe oPASS (Optical PAcket Switch Simulator), a simulation tool specifically designed for the evaluation of slotted Optical Packet Switching (OPS) switching architectures. oPASS is implemented in OMNET++, a general purpose eventdriven simulation framework. oPASS allows the evaluation of classical parameters in packet networks like packet loss probability and distribution of...

BACKGROUND Suicide may be conceptualized as an escape from intolerable predicaments, in particular, mental illness and environmental stressors. The operationalized predicaments of suicide (OPS) is a 4 category framework designed to assist in the classification of suicide. The objective was to examine whether this framework is potentially useful. METHODS 18 psychiatrists from 6 different count...

We propose a method of partitioning the set of all ip-ops in a circuit for multiple clock testing. In the multiple clock testing, ip-ops are partitioned into diierent groups and each group of ip-ops has an independent clock control. In our method, we use a test generator assuming an independent clock control for each ip-op. We than determine correlation between clock activity for all pairs of i...

the effect feeding olive-pulp silage (ops) for 120 days on several blood attributes was studied using 16 rams allotted to two diets consisting of 70% corn silage or 70% ops. olive-pulp silage feeding resulted in lower serum total protein, alanine aminotransferase, calcium and phosphorus levels and higher glucose concentration compared to the corn silage diet. body weight and other blood attribu...

This study used the Matching Pursuit (MP) method, a time-frequency analysis, to identify and characterize oscillatory potentials (OPs) in the primate electroretinogram (ERG). When the slow-sequence mfERG from the macular region of the retina was matched with Gabor functions, OPs were identified in two distinct bands: a high-frequency band peaking around 150 Hz that contributes to early OPs, and...

OBJECTIVES Occupational health service (OHS) for small-scale enterprises (SSEs) is still limited in many countries. Both Japan and the Netherlands have universal OHS systems for all employees. The objective of this survey was to examine the activities of occupational physicians (OPs) in the two countries for SSEs and to investigate their proposals for the improvement of service. METHODS Quest...
