The TPC/27 detector and the PEP machine have been upgraded for highluminosity running. We describe the performance of the new configuration during a test run in fall 1988. Prospects for progress in 7 physics, based on a large data sample to be recorded by the TPC/Zy detector, are reviewed.

Recent research has demonstrated the existence of a positive relationship between IT investment and productivity in the context of large firms. However, the validity of such relationship for small and medium enterprises (SMEs) has not yet been established. The issue is of critical importance for SMEs, which suffer a constant struggle for survival due to the absence of slack resources and high c...

Triple product correlations (TPC’s) involving strange quark spin are elucidated in b → uūs process within the standard model. They arise when light quark masses are nonzero. As the momenta and spins of constituent quarks are related to that of the parent hadron, the quark masses are, however small, important and relevant in TPC studies. At this level the TPC’s of interest are of the form ~ss · ...

Programming parallel machines has always been difficult, but the new multicore reality has triggered significant research projects such as those part of the DARPA HPCS challenge that put forth programmer productivity as on par with performance. Since programming models are crucial in supporting the programming of parallel machines, this raises the question of how the PLDI community should evalu...

the purpose of this study is to evaluate the impact of import of technology on iranian economy. we have used multi-sectoral and multi–regional computable general equilibrium gtap model. transfer of technology from one region to another is another factor effecting productivity. trade is one of the channels that speeds the transfer of technology. the effect of a ten percent productivity shock, in...

This study was conducted to characterize periphyton biomass, productivity, and algal species composition, and to examine how these parameters changed seasonally over the course of two years in Walker Branch, a temperate forest stream. Seasonal variations in several factors potentially controlling periphyton (irradiance, streamwater nutrient concentrations, temperature, and the incidence of seve...

The factors that explain differences in the economic productivity of urban areas have remained difficult to measure and identify unambiguously. Here we show that a synthesis of the classical representation of economic activity in a city in terms of a production function, together with a scaling perspective that accounts for the systematic effects of population size, leads to a new expression fo...

copolymerization of ethylene and propylene was investigated using a 4th generation phthalate ziegler-natta catalyst in normal hexane in a buchi reactor. the effects of different mole fractions of [al]/[ti], [si]/[al] and various amounts of hydrogen on productivity and weight percent of ethylene on the product, were studied. in the copolymerization reactions, tri-isobutyl aluminum (tibal) was us...

BACKGROUND According to current guidelines the cost of productivity loss should be considered in pharmacoeconomic analyses. The cost of health-related productivity loss in psoriasis patients is unknown. OBJECTIVE To estimate the cost of productivity loss in psoriasis and its association with health-related quality of life and clinical disease severity. METHODS Cross-sectional study, recruit...

OBJECTIVE Even though postpartum morbidity continues to cause high disease burden in maternal morbidity and mortality across the globe, the literature pertaining to resultant productivity loss is scarce. Hence, the present study aimed at determining the productivity loss and associated cost of episodes of postpartum ill health. METHODS A cross sectional study was conducted in two Medical Offi...
