We present faster overlap tests between spheres and either axis-aligned or oriented boxes. By utilizing quick rejection tests, faster execution times are observed compared to previous techniques. In addition, we present alternative vectorized overlap tests, which are compared to the sequential algorithms. Source code is available online.

An extension of the LQR/LQG methodology to systems with saturating actuators, referred to as SLQR/SLQG, where S stands for saturating, is obtained. The development is based on the method of stochastic linearization, whereby the saturation is replaced by a xed gain, calculated as a function of the variance of the signal at its input. Using the stochastically linearized system and the Lagrange mu...

PURPOSE Professional rejection is a frequent experience in an academic medical career. The authors sought to understand how rejection affects those pursuing such careers and why some individuals may be more resilient than others in a population of individuals with demonstrated ability and interest in research careers. METHOD Between February 2010 and August 2011, the authors conducted semistr...

INTRODUCTION AND OBJECTIVES Apoptosis has been implicated in the pathophysiology of various forms of heart disease. Acute cellular rejection leads to morbidity after heart transplantation and invasive techniques are needed for its diagnosis. We investigated the presence of cardiomyocyte apoptosis in transplanted hearts, its progression, its relationship with rejection, and the possibility that ...

OBJECTIVES The purpose of this study was to investigate the frequency and prognostic importance of acute cellular rejection after heart transplant. MATERIALS AND METHODS All 84 heart transplant patients at our center from January 1993 to January 2014, including all 576 endomyocardial biopsies, were evaluated with retrospective review of clinical records and endomyocardial biopsies. Routine an...

Graft failure of kidneys after transplantation is most often the consequence of the acute rejection. Hence, early detection of the kidney rejection is important for the treatment of renal diseases. In this chapter, authors introduce a new automatic approach to classify normal kidney function from kidney rejection using dynamic contrast enhanced magnetic resonance imaging (DCE-MRI). The kidney h...

The origins of the humoral theory of transplantation, which states that allografts are rejected by antibodies (and not directly by cells), can be traced back 100 years. This is when the method of detecting antibodies was first introduced. The methods for detection have become increasingly more sophisticated, permitting development of more specific proof of the hypothesis. Evidence has accumulat...

This paper presents a simple second-order controller that damps the resonance typical of piezoelectric nanopositioners and delivers good tracking performance. This method employs the Integral Resonant Control scheme (IRC) for damping the dominant resonant mode of the piezoelectric nanopositioner and uses an integral controller to achieve tracking performance. As disturbance rejection is a main ...

This paper deals with global disturbance rejection of nonlinear systems. The disturbance is assumed to be sinusoidal with completely unknown phases, amplitude, and frequencies, but the number of distinct frequencies or the order of the corresponding unknown linear exosystem is known. Different from the common structural assumptions of nonlinear systems needed in literature for disturbance rejec...

introduction: there has been an increasing interest in studies dealing with the relationship between mental disorders and color preference. this study was tailored to evaluate color preference or rejection in schizophrenic and normal subjects. materials and method: color preference and rejection of 58 patients with dsm-iv diagnosis of schizophrenia were compared with those of 52 normal subjects...
