It is very likely that the quantum description of spacetime is quite different from what we perceive at large scales, l ≫ (G~/c3)1/2. The long wavelength description of spacetime, based on Einstein’s equations, is similar to the description of a continuum solid made of a large number of microscopic degrees of freedom. This paradigm provides a novel interpretation of coordinate transformations a...

Bailey, D.W., Walker, J.W. and Rittenhouse, L.R., 1990. Sequential analysis of cattle location: day-to-day movement patterns. Appl. Anita. Behav. Sci., 25: 137-148. Studies were conducted in Texas and Colorado to determine if there were consistent movement patterns of grazing cattle. Based on optimal foraging theory, we hypothesized that cattle would select the same area of a pasture to graze f...

Improving the performance of distant speech recognition is of considerable current interest, driven by a desire to bring speech recognition into people’s homes. Standard approaches to this task aim to enhance the signal prior to recognition, typically using beamforming techniques on multiple channels. Only few real-world recordings are available that allow experimentation with such techniques. ...

The aim of this paper is to understand what a recession means for individual consumers, and to model in a life-cycle framework how individuals respond to recessions. Our focus is on the sharp increase in savings rates that have been observed in the current and recent recessions. We show empirically that these saving spikes were short-lived and common to all working age groups. We then study lif...

SIR—We read with interest the research letter by Larner about the clinical utility of the Addenbrooke's Cognitive Examination-Revised (ACE-R) [1]. In this study, we presume that the ACE-R was compared to a comprehensive clinical evaluation (a history, physical and cognitive examination plus pertinent investigations) performed by a clinician blinded to the test score. The results obtained make u...

BACKGROUND Intra-abdominal infections are one of the most common infections encountered by a general surgeon. However, despite this prevalence, standardized guidelines outlining the proper use of antibiotic therapy are poorly defined due to a lack of clinical trials investigating the ideal duration of antibiotic treatment. The aim of this study is to compare the efficacy and safety of a three-d...

Moral perceptions and judgments are based on a society's values. Professional ethics generally complement social codes and reinforce moral perceptions. In the area of health care, the doctor-patient relationship is inherently unequal, placing added responsibilities on those providing care. In countries like India where practice protocols and referral pyramids are not defined and where patient a...

Day-to-day variation of the corrected orthogonial electrocardiogram was investigated in 20 normal subjects. Ten recordings were made in each individual witlh chest electrode positions left unmarked first, after which 10 subjects underwent another series of 10 consecutive daily recordings with marked electrode locations. Mean and maximal day-to-day variations of durations and amplitudes of diffe...
