Introduction:In an ideal parallel-hole collimator, thickness of septal material should be sufficient to stop more than 95% of incident photons. However, some photons pass the septa without interaction or experience scattering before they reach the detector. In this study, we determined different contribution of collimator responses consist of geometrical response, septal penetr...

The study aim was to identify predictors of impaired oral health-related quality of life (OHRQoL). Employees of five companies were offered a clinical full-mouth examination. Oral health-related quality of life was measured with the German version of the Oral Health Impact Profile (OHIP) and summarized as additive scores (OHIP-ADD) and as prevalence of negative impacts (OHIP-SC). Two logistic r...

Due to the impact of pandemic (COVID-19) crisis and inflation threat, not only do companies change their production models, but also operating modes. The purchase mode consumers, moreover, are changed. These changes make social commerce (SC) more popular. However, there exist problems in SC. Therefore, is purpose this study examine role a user’s perceived past negative experience (PPNE) trust S...

During development, retinal ganglion cell axons establish a topographically ordered projection from the retina to the superior colliculus (SC). The putative guidance activities for retinal axons that operate during embryonic development are not detectable in the normal adult SC. However, these cues reappear upon transection of the optic nerve of adult rats. In the present study, we used a modif...

A major challenge in computational neurobiology is to understand how populations of noisy, broadly-tuned neurons produce accurate goal-directed actions such as saccades. Saccades are high-velocity eye movements that have stereotyped, nonlinear kinematics; their duration increases with amplitude, while peak eye-velocity saturates for large saccades. Recent theories suggest that these characteris...

When considering the effect of quantum noise (QN) in a phase-insensitive linear amplifier or attenuator, it is customary to use the single-channel Caves model (SC-CM). Although this model is valid in simple situations, such as the presence of a beam splitter, it is not necessarily valid when a system with many degrees of freedom is involved. In order to address this issue, we consider in this p...

Automatically verifying multi-threaded programs is difficult because of the vast number thread interleavings, a problem aggravated by weak memory consistency. Partial orders can help with verification they represent many interleavings concisely. However, there no dedicated decision procedure for solving partial-order constraints. In this article, we propose novel ordering consistency theory con...

BACKGROUND Renal dysfunction is an independent predictor of morbidity and mortality in cardiac surgery. For a better assessment of renal function, calculation of creatinine clearance (CC) may be necessary. OBJECTIVE To objectively evaluate whether CC is a better risk predictor than serum creatinine (SC) in patients undergoing cardiac surgery. METHODS Analysis of 3,285 patients registered in...
