objective(s):intermittent hypoxia (ih), caused by obstructive sleep apnea (osa), could cause hippocampus or neuron damage through multiple signaling pathways, while the underlying mechanisms are still unclear. thus, the present study aimed to explore the effect of ih on the biological functions of microglia cells. materials and methods:cell proliferation of bv2 cells after exposure to ih were o...

Event sequence, asynchronously generated with random timestamp, is ubiquitous among applications. The precise and arbitrary timestamp can carry important clues about the underlying dynamics, and has lent the event data fundamentally different from the time-series whereby series is indexed with fixed and equal time interval. One expressive mathematical tool for modeling event is point process. T...

we consider the coupled system$f(x,y)=g(x,y)=0$,where$$f(x, y)=bs 0 {m_1}   a_k(y)x^{m_1-k}mbox{ and } g(x, y)=bs 0 {m_2} b_k(y)x^{m_2-k}$$with entire functions $a_k(y), b_k(y)$.we    derive a priory estimates  for the sums of the rootsof the considered system andfor the counting function of  roots.

the authors of “management matters: a leverage point for health systems strengthening in global health,” raise a crucial issue. because more effective management can contribute to better performing health systems, attempts to strengthen health systems require attention to management. as a guide toward management capacity building, the authors outline a comprehensive set of core management compe...
