Hfq is a posttranscriptional riboregulator and RNA chaperone that binds small RNAs and target mRNAs to effect their annealing and message-specific regulation in response to environmental stressors. Structures of Hfq-RNA complexes indicate that U-rich sequences prefer the proximal face and A-rich sequences the distal face; however, the Hfq-binding sites of most RNAs are unknown. Here, we present...

Nonlinear rescaling (NR) methods alternate finding an unconstrained minimizer of the Lagrangian for the equivalent problem in the primal space (which is an infinite procedure) with Lagrange multipliers update. We introduce and study a proximal point nonlinear rescaling (PPNR) method that preserves convergence and retains a linear convergence rate of the original NR method and at the same time d...

Objective- To measure statistically bone cortex to diameter  (C/D) ratio in metocarpo/metatarsal and proximal phalanges in camel. This ratio may be used in diagnosing possible metabolic and nutritional diseases in camel. Design- Experimental study. Animals- Twelve camel limbs (6 fore limbs & 6 hind limbs)      Procedures- This study was conducted on dorsopalmar/dorsoplantar radiographs of t...

This article introduces a generalization of discrete Optimal Transport that includes a regularity penalty and a relaxation of the bijectivity constraint. The corresponding transport plan is solved by minimizing an energy which is a convexification of an integer optimization problem. We propose to use a proximal splitting scheme to perform the minimization on large scale imaging problems. For un...

introduction: intramedullary nailing (imn) of high tibia fracture has some mechanical and biological advantages over the other form of fixation. however, valgus, apex anterior malalignment and anterior displacement of proximal fragment commonly occur after isolated imn fixation of proximal high tibia fracture. the purpose of this study is to determine the effectiveness of using 3.5-mm locking c...

In this paper, we first give a new definition of Ω-Dedekind complete Riesz space (E,≤) in the frame vector metric (Ω,ρ,E) and investigate relation between Dedekind our concept. Moreover, introduce contraction so called α-vector proximal mapping. Then, prove certain best proximity point theorems for such mappings spaces where is space. Thus, time, acquire results on spaces. As result, generalize...

recurrent dislocation is not common in small joints. this report presents a new case of chronic recurrent dislocation of proximal interphalangeal joint of the finger in which soft tissue injuries have a role in the dislocation. the patient was a 23 years old man who had referred to our center because of recurrent dislocation of proximal interphalangeal joint of his right ring finger during spor...

conclusions closed reduction and hybrid external fixation can be used as a definitive treatment for severe comminuted fractures of the distal femur and proximal tibia, when the concomitant contusion of the skin and soft tissue damage prohibits safe open reduction and internal fixation. patients and methods in a prospective study, 44 patients with comminuted fractures of the distal femur or prox...
