An algorithm for improved automatic segmentation of gross anatomical structures of the human brain is presented that merges the output of a tissue classification process with gross anatomical region masks, automatically defined by non-linear registration of a given data set with a probabilistic anatomical atlas. Experiments with 20 real MRI volumes demonstrate that the method is reliable, robus...

We study the perturbation due to rotating shockwaves in Banados-Teitelboim-Zanelli geometries at late times and analyze change mutual information between two subsystems belonging dual ${\mathrm{CFT}}_{L}$ ${\mathrm{CFT}}_{R}$. find that scrambling of is general governed by Lyapunov index ${\ensuremath{\lambda}}_{L}$ which bounded $\ensuremath{\kappa}=\frac{2\ensuremath{\pi}}{\ensuremath{\beta}(...

A functional B cell antigen receptor is thought to regulate antibody gene rearrangement either by stopping further rearrangement (exclusion) or by promoting additional rearrangement (editing). We have developed a new model to study the regulation of antibody gene rearrangement. In this model, we used gene targeting to replace the J kappa region with a functional V kappa-J kappa light chain gene...

A multi-species magnetized collisional nonthermal plasma system containing inertial ion species, non-inertial electron species following $\kappa-$ distribution, and immobile dust particles, is considered to examine the characteristics of dissipative dust-ion-acoustic (DIA) soliton modes, \textbf{theoretically parametrically}. The electrostatic solitary modes are found be associated with low fre...

Abstract In this paper, we consider the small-convection limit of chemotaxis-Navier–Stokes system with logarithmic sensitivity and logistic-type source $$ \textstyle\begin{cases} n^{\kappa}_{t}+\boldsymbol{u}^{\kappa}\cdot \nabla{n}^{\kappa}= \Delta{n}^{\kappa}-\chi \nabla \cdot ({n^{\kappa}}\nabla \log{c^{\kappa}})+f(n^{\kappa}), &x\in \Omega , t>0, \\ c^{\kappa}_{t}+\boldsymbol{u}^{\ka...

background and objectives: antibacterial susceptibility testing of clinical bacterial isolates through disk diffusion method plays a major role in antibacterial treatment. one of the main factors affecting the result of these tests is the type, structure and quality of the disks. the main objective of this study was to compare the agreement of antibiotic disks originated from three companies on...

objective: to examine the inter-rater reliability of triages performed by the electronic triage system (ets) which has recently developed and used in hospital emergency department (ed). methods: this cross-sectional study was conducted prospectively and studied 408 visitors of tabriz imam reza hospital’s ed. the variables of interest were age, sex, nurse-assigned triage category, physician-assi...

BACKGROUND Laryngotracheal stenosis as a late complication of prolonged endotracheal intubation is a life-threatening event. In order to determine the related risk factors for this complication, which may vary among different countries, designing a valid questionnaire is necessary. The aim of this study was to select the items and evaluate the face and content validities of a questionnaire deve...
