Despite appropriate management of distal radius fractures, TFCC tears and DRUJ instability in the acute setting, a subset of patients will have ongoing pain or instability of the DRUJ. Ongoing instability is thought to eventually lead to pain, loss of motion and degenerative changes due to alterations in normal kinematics of the joint, although there is little in the literature to support this ...

The paper at hand aimes at identifying the assumptions that lead to the results presented in an article by Michael Macy and Yoshimichi Sato published in PNAS. In answer to a failed replication, the authors provided the source code of their model and here the results of carefully studying that code are presented. The main finding is that the simulation program implements an assumption that is mo...

purpose : to report a case of retained silicone tube case report : we report a case of 48-year-old iranian lady who referred to the department of otolaryngology with 18 years history of epiphora and intermittent mucopurulant discharge from the left lacrimal canaliculi. she had external dacryocystorhinostomy (dcr) with silicon stenting for epiphora 18 years ago but epiphora had continued after s...

Robot learning from demonstration (RLfD) seeks to enable lay users to encode desired robot behaviors as autonomous controllers. Current work uses a human’s demonstration of the target task to initialize the robot’s policy, and then improves its performance either through practice (with a known reward function), or additional human interaction. In this article, we focus on the initialization ste...

In the 1960s, a new idea for combating poverty emerged that promised a revolutionary change for American social welfare policy. Though the idea had a complex history, one of its main justifications was articulated by a commis­ sion appointed by President Johnson to evaluate the nation’s antipoverty pro­ grams. The commission, which was made up primarily of business leaders and economists, issue...

Traditional security policies largely focus on access control. Though essential, access control is only one aspect of security. In particular, the correct behavior and reliable operation of a system depends not only on what users are permitted to do, but oftentimes on what users are required to do. Such obligatory actions are integral to the security procedures of many enterprises. Unlike acces...

Background: Failed fertilization post ICSI has been mainly attributed to the sperm’s inability to induce oocyte activation. Phospholipase C Zeta (PLCζ) is considered to be a primary factor for the induction of oocyte activation. The aim of this study was to quantitatively assess the expression of PLCζ in globozoospermic or individuals with previous low or failed fertilization in comparison to f...
