Background: The amount of average dose enhancement in tumor loaded with 10B may vary due to various factors in boron neutron capture therapy.Objective: This study aims to evaluate dose enhancement in tumor loaded with 10B under influence of various factors and investigate the dependence of this dose enhancement on neutron spectra changes.Material and Methods: In this simulation stud...

One research tradition has distinguished self-deception, the tendency to give favorably biased but honestly held self-descriptions from impression management, the tendency to give favorable selfdescriptions to others. A 2nd tradition has distinguished enhancement, the claiming of positive attributes, from denial, the repudiation of negative attributes. The 2 distinctions were evaluated jointly ...

This paper presents a new speech enhancement approach originated from factor analysis (FA) framework. FA is a data analysis model where the relevant common factors can be extracted from observations. A factor loading matrix is found and a resulting model error is introduced for each observation. Interestingly, FA is a subspace approach properly representing the noisy speech. This approach parti...

It is commonly assumed that reaction measurements for astrophysics should be preferably performed in the direction of a positive Q value to minimize the impact of the stellar enhancement factor, i.e., the difference between the laboratory rate and the actual stellar rate. We show that the stellar effects can be minimized in the charged particle channel, even when the reaction Q value is negativ...

A general method is presented for calculating the field enhancement factor of cylindrically symmetric high aspect ratio conductive structures. A discrete distribution of charges is used on the symmetry axis to replace the real charge distribution such that the electrostatic potential satisfies a set of boundary conditions. Their number will be set through a self-validating process. The method i...

Leukotriene B4 (LTB4) is a potent primary stimulator of neutrophil chemotaxis, aggregation. and degranulation and induces superoxide production at higher concentrations. In order to determine whether LTB4 modulates neutrophil responses to oxidative stimuli, human neutrophils (PMNs) were incubated with LTB4 prior to stimulation with fMet-Leu-Phe (fMLP. 1 0 mol/L). opsonized zymosan (OZ. 250 tg/m...

Loading and hauling machineries are highly capital intensive equipment to procure, operate and maintain in surface mining operation. It must be borne in mind that with this huge and capital-intensive equipment, every second of its life time is absolutely important from the production and productivity point of view. As such, it is imperative to optimize the overall cycle time and speed factor of...

In laser structures where the active region consists of several quantum wells, non-uniform charge injection can occur. We examine the consequences of non-uniform charge injection on gain, threshold current, and linewidth enhancement factor. Non-uniform charge injection in a InP-based multiple quantum well laser was considered in order to analyze effects on gain, threshold current, and linewidth...
