A new Monte Carlo (MC) algorithm, the 'dose planning method' (DPM), and its associated computer program for simulating the transport of electrons and photons in radiotherapy class problems employing primary electron beams, is presented. DPM is intended to be a high accuracy MC alternative to the current generation of treatment planning codes which rely on analytical algorithms based on an appro...

The concept of overcoming multidrug resistance using modulators is based on the hypothesis that there will be a synergistic interaction between the modulator and the cytotoxic agent. We examined the ability of dipyridamole (DPM) to synergistically enhance drug sensitivity in drug-sensitive KB-3-1 cells and their drug-resistant variants, KB-GRC1 and KBV1 cells, using median effect analysis to pr...

OBJECTIVE To compare dental plaster model (DPM) and cone-beam computed tomography (CBCT) in the measurement of the dental arches, and investigate whether CBCT image artifacts compromise the reliability of such measurements. MATERIALS AND METHODS Twenty patients were divided into two groups based on the presence or absence of metallic restorations in the posterior teeth. Both dental arches of ...

Some difficulties are often encountered when studying the conformation of saccharides by means of p.m.r. spectroscopy: the spectra are rather complex so that coupling constants and chemical shifts of the particular protons cannot be distinguished. The introduction of certain complexes of lanthanides possessing paramagnetic pro­ perties, so-called "shift reagents", into this field was of great i...

The effects of endurance training (running 40 m/min grade for 60 min, 5 days/wk for 8 wk) on skeletal muscle lactate removal was studied in rats by utilizing the isolated hindlimb perfusion technique. Hindlimbs were perfused (single-pass) with Krebs-Henseleit bicarbonate buffer, fresh bovine erythrocytes (hematocrit approximately 30%), 10 mM lactate, and [U-14C]lactate (30,000 dpm/ml). Arterial...

INTRODUCTION The present study aimed to evaluate a rapid and inexpensive colorimetric nitrate reductase assay (NRA) performed directly on sputum specimens for detection of drug resistance in Mycobacterium tuberculosis (MTB). METHODOLOGY A total of 55 sputum samples were decontaminated and processed by modified Petroff's method.  A part of the resulting suspension was used to perform direct NR...

Direct insertion of the anterior papillary muscle (DPM) into the mitral valve is uncommon. During the routine dissection of an adult female, a DPM into the mitral valve with abnormal chordae tendinae was observed. This abnormal papillary muscle was measured as 28.0 mm in length from myocardial to insertion, 14.8 mm in width, and 7.0 mm in depth. The embryology, symptoms, associated cardiac dise...

Dynamic Power Management (DPM) is one of the main system level low power technologies for Systems On Chip (SOCs). This paper presents a series of Markov models for various DPM policies and provides accurate analysis about their power and latency performances with full consideration of the shutdown and wakeup processes. The new models make it possible to incorporate latency analysis in terms of ...

This article provides next step towards solving speed bottleneck of any system that intensively uses convolutions operations (e.g. CNN). Method described in the article is applied on deformable part models (DPM) algorithm. Method described here is based on multidimensional tensors and provides efficient tradeoff between DPM performance and accuracy. Experiments on various databases, including P...

Facial feature detection is considered an important computer vision task that is used for many real world applications. Current advancements in computer vision have come up with many proposed facial feature detection approaches, such as Deformable Parts Model (DPM), that provide good accuracy in the detection of key facial features, but mainly in frontal poses. When presented with side profile ...
