results totally, 20 patients completed the study. the cms and pain scores significantly improved after the block. conclusions the use of the modified lateral ssnb of feigl significantly reduces pain and increases shoulder function, in chronic shoulder pain. patients and methods patients were evaluated using the constant-murley score (cms) and number rating scale values for pain. the ssn was blo...

background: identifying the predisposing factors of neck and shoulder complaints and finding solutions to avoid them could improve the occupational health condition of the nurses. in this study, we aimed at determining the role of psychological and physical occupational factors in developing neck and shoulder complaints among the participants.   methods: this analytic cross-sectional study was ...

There is now substantial evidence that during visual search, previously searched distractors are stored in memory to prevent them from being reselected. Studies examining which memory resources are involved in this process have indicated that while a concurrent spatial working memory task does affect search slopes, depleting visual working memory (VWM) resources does not. In the present study, ...

We approximate the objective function of the fixed charge network flow problem (FCNF) by a piecewise linear one, and construct a concave piecewise linear network flow problem (CPLNF). A proper choice of parameters in the CPLNF problem guarantees the equivalence between those two problems. We propose a heuristic algorithm for solving the FCNF problem, which requires solving a sequence of CPLNF p...

We describe an application of the Legendre transform to communication networks. The Legendre transform applied to max-plus algebra linear systems corresponds to the Fourier transform applied to conventional linear systems. Hence, it is a powerful tool that can be applied to max-plus linear systems and their identification. Linear max-plus algebra has been already used to describe simple data co...

The fluorescence intensity profiles of thin cross-sections of human lenses were determined as a function of age by scanning microspectrofluorimetry with blue light excitation close to that available in conventional slit-lamp examination (filter transmission maximum 410 nm). The fluorescence intensity of the entire nuclear region increased with age. The profile of the adult lens was manifested a...

1. introduction mountain regions are increasingly endangered by a variety of disaster, including avalanche, debris flows, and rock slide. some characteristics such as elevation, angle of slope, vegetation and climatic elements could affect the avalanche event. indeed, avalanche is the second factor in soil erosion that causes demolition; therefore, it threatens the food safety. iran has two mai...

Based on empirical Levy-type concentration functions a new graphical representation of the ML-density estimator under order restrictions is given. This representation generalizes the well-known representation of the Grenander estimator of a monotone density as the slope of the least concave majorant of the empirical distribution function. From the given representation it follows that a density ...

We prove the convergence of the extremal processes for variable speed branching Brownian motions where the ”speed functions”, that describe the timeinhomogeneous variance, lie strictly below their concave hull and satisfy a certain weak regularity condition. These limiting objects are universal in the sense that they only depend on the slope of the speed function at 0 and the final time t. The ...
