Introduction. Perioperative pain management associated with hip surgery is challenging. The pericapsular nerve group (PENG) block a new technique thought to provide better postoperative analgesia in addition its motor-sparing effects. Aim. This review aims evaluate the safety and efficacy of PENG blockade managing patients undergoing surgery. Methods. literature was reviewed through four electr...

Censored quantile regression has recently been studied under two major approaches: one is based on Portnoy (2003) that adopts self-consistent principle for handling censoring and the other one is based on Peng and Huang (2008) that utilizes the martingale structure of randomly censored data. Though numerical studies have suggested the close proximity between these two methods, their underlying ...

Peng et al. (1) conclude that a fast increase in the mass absorption cross-section (MAC) of black carbon (BC) in urban environments leads to significantly increased estimates of the BC radiative forcing (RF). Their chamber measurements are highly valuable and complement observations performed in ambient conditions, but their “enhancement factor” relative to an unspecified baseline may not be di...

The modeling of complex risk situations imposes the existence of multiple ways to represent the risk and compare the risk situations between them. In probabilistic models, risk is described by random variables and risk situations are compared by stochastic dominance. In possibilistic or credibilistic models, risk is represented by fuzzy variables. This paper concerns three indicators of dominan...

Peng, Bin. Convergence, Rank Reduction and Bounds for the Stationary Analysis of Markov Chains (Under the direction of William J. Stewart). With existing numerical methods, the computation of stationary distributions for large Markov chains is still time-consuming, a direct result of the state explosion problem. In this thesis, we introduce a rank reduction method for computing stationary distr...

In this paper we respond to calls for an institution-based perspective on strategy. With its emphasis upon mimetic, coercive, and normative isomorphism, institutional theory has earned a deterministic reputation and seems an unlikely foundation on which to construct a theory of strategy. However, a second movement in institutional theory is emerging that gives greater emphasis to creativity and...
