the relative stability of hydrogen-bonded of molybdate-phosphonic acid (mpa) complex (1:2) ingas phase has been carried out using density functional theory (dft) methods. the methods are usedfor calculations are b3lyp, bp86 and b3pw91 that have been studied in two series of basis sets: d95**and 6-31+g(d,p) for hydrogen and oxygen atoms; lanl2dz for mo and phosphorus. predictedhydrogen-bond geom...

At present, span-based entity recognition methods are mainly used to accurately identify the span (entity) boundary for recognition, in which relative position information of and words region routinely ignored. This can be improve performance. Therefore, a nested model, integrates within span, is proposed. The representation first obtained with triaffine attention. Then, word region, as well pr...

BACKGROUND Ruptures of the lateral ankle ligaments are very common; however, treatment remains controversial. The aim of the current study was to perform a meta-analysis of randomized, controlled clinical trials of existing treatment strategies for acute ruptures of the lateral ankle ligaments. METHODS Randomized, controlled trials reported between 1966 and 1998 were included if they involved...
