Trapped carriers’ effects on the electric field distribution are believed to be responsible for the difference of the G-V(ds)(1/2) Slopes in the different drain-sources regions, which is in accord with the experimental results of the hydrogen annealing treatment. The carrier mobility is also discussed based on the measurement of
gate voltage dependence of the drain-source current. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3204669]“
“Background: Several randomized trials have shown that cardiac resynchronization therapy (CRT) benefits New York Heart Association (NYHA) functional class I/II heart failure (HF) patients, see more but it is unknown if similar outcomes occur in the real-world.
Methods and Results: All patients receiving CRT between 2003 and 2008 with ejection fraction (EF) <= 35% and QRS duration >= 120 ms were included. Outcomes assessed were subjective clinical response, echocardiographic response, and survival free of cardiovascular (CV) hospitalization. Baseline demographics in functional class I/II (n = MEK inhibitor 155) and functional class III/IV (n = 512) were similar, except for differences in age and several comorbidities. Clinical response was similar in both groups. The functional class I/II group had a greater decrease in left ventricular (LV)
end-diastolic dimension (P = .031), and trended toward greater improvements in LV end-systolic dimension (P = .056) and EF (P = .059). The functional class I/II group had a better 5-year survival rate (79 vs 54%; P < .0001) and survival free of CV hospitalization (45% vs 26%; P < .0001).
Conclusions: In this real-world clinical scenario, NYHA functional class I/II CRT patients improved clinical status, and LV function and size as good as or better than those in NYHA functional class III/IV patients. These observations provide further support for the use of CRT in patients with mild symptoms of HF. (J Cardiac Fail 2012;18:373-378)”
“In a recent study, Rigosertib chemical structure a two-dimensional solubility
parameter model was used to correlate the heat of solution for Solutes ranging from n-alkanes to alcohols, dissolved in isotatic polypropylene (PP), poly(ethyl ethylene) (PEE), and poly(dimethylsiloxane) (PDMS). When literature data Of solubility parameter components of solutes were used, the correlation had some scattering for solutes with low values of cohesive energy density. In this study, the components Of solubility parameters of solutes and polymers were estimated from cohesive energy and heat of sorption Of solutes. Good correlation was obtained for the specific heat of sorption (Delta U(sorp)/V) for Solutes ranging from n-alkanes to alcohols, and PDMS had a polar component as previously estimated. Free volume effect in solution process may be the Source of a small systematic deviation from the model.
