We discuss some ways in which topos theory (a branch of category theory) can be applied to interpretative problems in quantum theory and quantum gravity. In Section 1, we introduce these problems. In Section 2, we introduce topos theory, especially the idea of a topos of presheaves. In Section 3, we discuss several possible applications of topos theory to the problems in Section 1. In Section 4...

OBJECTIVE To assess the value of a cardiac technicians' report on electrocardiographs (ECGs) in reducing serious errors of interpretation by senior house officers. METHODS A parallel study of interpretation of ECGs by senior house officers from 238 cases seen in an accident and emergency (A&E) department in a teaching hospital. 129 ECGs were reported by a cardiac technician at the time of rec...

In the context of an imitation game, 12- and 18-month-old infants saw an adult do such things as make a toy mouse hop across a mat (with sound effects). In one condition (House), the adult ended by placing the mouse in a toy house, whereas in another condition (No House) there was no house present at the final location. Infants at both ages usually simply put the mouse in the house (ignoring th...

BACKGROUND Prolongation of action potential duration (APD), increased spatial APD dispersion, and triangulation are major factors promoting drug-induced ventricular arrhythmia. Preclinical identification of HERG/IKr-blocking drugs and their pro-arrhythmic potential, however, remains a challenge. We hypothesize that transgenic long-QT type 1 (LQT1) rabbits lacking repolarizing IKs current may he...

the present research with an emphasis on coffee houses at qajar age has recognized motives and effect of social and political factors such as conditional event in formation of art traditions in coffee house so as to examine the communication function of coffee house painting at this space. coffee house at qajar age has been found as a place for people’s gathering which had communicative-cultura...

Two repeated experiments were conducted to investigate the effects of different stocking densities onbroiler performance, carcass characteristics, litter quality and foot lesionsusing 5224 one day-old Ross 308 broilers. In each experiment, a total of 2612 one day-old broilers were allocated in 16 floor pens at densities of 16, 18, 20 and 22 birds/m2 of floor space in an environmentally controll...

The new Allen Center for Business Activities is nearing completion between the Cohen House Faculty Club and the old wing of Baker College. The million dollar building was a gift f rom Mr. and Mrs. Herbert Allen. The center, to be finished in June, will house treasurer, cashier, accounting, campus business, and development offices. In addition, the building will be a temporary home for offices a...

An automated monitoring system for home health care has been designed for an experimental house in Japan called the Welfare Techno House (WTH). Automated electrocardiogram (ECG) measurements can be taken while in bed, in the bathtub, and on the toilet, without the subject's awareness, and without using body surface electrodes. In order to evaluate this automated health monitoring system, overni...
