• omission failures: a service is asked for but never rendered. The client might wait forever or be notified about the failure (termination) of the service. • commission failures: a service initiates unexpected actions, e. g., communication that is unexpected by the receiver. The service might wait forever, causing omission failures for subsequent calls by clients. The receiver might be hindere...

This paper presents herein experiments and calculations of electromagnetic induction between jointless track circuits (JTCs) and track-circuit readers (TCRs). The paper uses transmission-line theory to simulate JTC currents ahead of shunt points and electromagnetism to calculate voltages induced in the TCR antenna. Based on these calculations, the JTC-to-TCR range is defined. The paper derives ...

This study examines how judgments of a region's contrast are influenced by components of a heterogeneous surround. Each stimulus comprised a 5x5 grid of squares in a homogeneous background of fixed mean luminance, with the central square the target. On a given trial, the task was to judge (with feedback) whether the (Weber) contrast of the target was 0.04 or -0.04 (relative to the background); ...

Background Pulmonary hypertension (PH) in congenital heart disease affects the patient’s prognosis. Prolonged QRS and QTc intervals in ECG may intensify life-threatening dysrhythmia in patients. We aimed to investigate the correlation between QRS, QTc, and JTc intervals prolongation in ECG with PH in Congenital Heart Disease (CHD) patients. Mate...

A new kind of computer-generated hologram termed digital correlation hologram (DCH) has been developed and demonstrated with promising results. This hologram is composed of two separate sub-holograms. The reconstructed image is obtained as a result of a spatial correlation between the hologram's two parts. The DCH codes two complex functions which are generated by an iterative optimization proc...

The Aggregate Level Simulation Protocol (ALSP) resulted from a U.S. Defense Advanced Research Projects Agency (DARPA) effort to identify mechanisms suitable to facilitate the integration and interoperation of existing (so-called “legacy”) constructive training simulations. The Joint Training Confederation (JTC) – the primary application of ALSP – has evolved from two models in 1992 to twelve in...

BACKGROUND Prolongation of the QT interval is considered a risk factor for cardiac adverse events and mortality. Left bundle branch block (LBBB) lengthens the QT interval. The corrected QT interval (QTc) is most likely overestimated because its prolongation is caused by increases in depolarization duration and not in repolarization. OBJECTIVES In this study, we aimed to apply corrected JT int...

Sudden cardiac death in myotonic dystrophy type I (DM1) patients can be attributed to atrioventricular blocks as far as to the development of life-threatening arrhythmias which occur even in hearts with normal left ventricular systolic and diastolic function. Heterogeneity of ventricular repolarization is considered to provide an electrophysiological substrate for malignant arrhythmias. QTc dis...

A dye transfer method was applied to investigate the effect of testosterone on gap junctional intercellular communication (IC) of two kinds of human transitional cell carcinoma cell lines, JTC-30 and JTC-32. When JTC-30 cells were cultured with testosterone at nontoxic concentrations (17-69 microM), a dose and time dependent inhibition of dye transfer was observed. More than 90% inhibition occu...

This study examined relationships between positive affect and jumping to conclusions (JTC) in delusional thinking. One hundred and eighty-nine non-clinical participants entered an internet experiment and were randomized into one of two conditions. Those in a positive condition performed online creativity tasks and received bogus positive feedback as part of a positive affect induction procedure...
