background: prediction of the absorbed dose in irradiated volume plays an important role in the outcome of radiotherapy. application of small fields for radiotherapy of thorax makes the dose calculation process inaccurate due to the existence of electronic disequilibrium and intrinsic deficiencies in dose calculation algorithms. to study the lung absorbed dose in radiotherapy with small fields,...

By limiting filling, abnormalities of right ventricular (RV) diastolic function may impair systolic function and affect adaptation to disease. To quantify diastolic RV pressure-volume relations and myocardial compliance (MC), a new sigmoidal model was developed. RV micromanometric and sonomicrometric data in alert dogs at control (n = 16) and under surgically induced subacute (2-5 wk) RV pressu...

BACKGROUND Pasteurized bone grafting is used following the excision of a bone tumor for the purpose of eliminating neoplastic cells while preserving bone-inducing ability. In the hopes of guaranteeing the most favourable results, the establishment of an animal model has been urgently awaited. In the course of establishing such a model, we made a preliminary examination of the effect of muscle c...

One of the key challenges in human action recognition from video sequences is how to model an action sufficiently. Therefore, in this paper we propose a novel motion-based representation called Motion Context (MC), which is insensitive to the scale and direction of an action, by employing image representation techniques. A MC captures the distribution of the motion words (MWs) over relative loc...

BACKGROUND Within-person variation in dietary records can lead to biased estimates of the distribution of food intake. Quantile estimation is especially relevant in the case of skewed distributions and in the estimation of under- or over-consumption. The analysis of the intake distributions of occasionally-consumed foods presents further challenges due to the high frequency of zero records. Two...

This paper investigates the behavioral response to male circumcision (MC) for HIV/AIDS prevention. Recent evidence from randomized controlled trials (RCTs) indicates that medically performed MC significantly reduces men’s risk of acquiring HIV through sexual intercourse. However, HIV/AIDS incidence will not necessarily fall if the lowered risk of infection induces a higher propensity for risky ...

The dose delivered to patients during computed tomography (CT) exams has increased in the past decade. With the increasing complexity of CT examinations, measurement of the dose becomes more difficult and more important. In some cases, the standard methods, such as measurement of the computed tomography dose index (CTDI), are currently under question. One approach to determine the dose from CT ...

With the proliferation of mobile devices, studies on Mobile Commerce (MC) adoption have received increasing attention from researchers in Information Technology. While there are many studies in the literature that have investigated MC adoption by individuals, these studies mainly investigate the factors that lead to usage. However, they do not examine how individuals may progress or mature from...
