چکیده
We examine, in a discrete-stochastic setting, the benefits and liabilities of replacing the three-reaction set 1 2 3 S S S → ⇌ with a single 3 S -producing reaction. We develop a novel criterion for deciding whether such an abridgment can be accomplished in a way that accurately replicates the production of 3 S molecules, and we derive a formula for estimating the consequent speedup in stochastic simulation. We show that in all cases in which such an abridgment can be done accurately and with a significant gain in simulation speed, a procedure called the slow-scale stochastic simulation algorithm provides a robust and theoretically transparent way of implementing the abridgment.

Silanetriols in the gas phase: single molecules vs. hydrogen-bonded dimers.
The first gas phase structure of a silanetriol, tert-butylsilane-triol [(t)BuSi(OH)(3)], determined by gas electron diffraction (GED), is reported. Quantum chemical calculations have been performed to elucidate potential intermolecular interactions between silanetriol molecules in the gas phase. The results are set into contrast to solid state structures of (t)BuSi(OH)(3) and related compounds.

Despite the advancement in the Malaysian rural healthcare centers operations, the healthcare delivery is currently facing some challenges caused by the techniques in collecting the data for analyzing their performances at the end of the day. It is posited that healthcare centers can take advantages of these data and explore analytics as a competitive tool provided by Business Intelligence (BI)....
متن کامل‘I wouldn’t say it’s sexism, except that … It’s all these little subtle things’: Healthcare scientists’ accounts of gender in healthcare science laboratories
We explore healthcare scientists’ accounts of men in healthcare science laboratories. By focussing on subtle masculinist actions that women find disadvantageous to them, we seek to extend knowledge about women’s under-representation in senior positions in healthcare science – despite women being in the majority at junior levels. We maintain that healthcare science continues to be dominated by t...

Structural localization of the O2-evolving apparatus to multimeric (tetrameric) particles on the lumenal surface of freeze-etched photosynthetic membranes
Isolated appressed chloroplast membranes, highly enriched in photosystem II (PSII) activity, were examined by freeze-etch electron microscopy. The exposed surfaces of these Triton X-100 solubilized membrane fragments correspond to the lumenal or ESs surface of intact stacked thylakoid membrane regions (Dunahay, T. G., L. A. Staehelin, M. Seibert, P. D. Ogilvie, and S. P. Berg. 1984. Biochim. Bi...
