OBJECTIVE To evaluate the normal antral wall thickness on MDCT and to determine the optimal cut-off value for differentiating normal and benign from malignant gastric wall thickening. MATERIAL AND METHOD MDCT scans of 154 patients, 22 malignancies, 66 benign conditions, and 66 normal findings, whose underwent both gastroscopy and MDCT within 30 days were retrospectively reviewed. The degree o...

The position of a flash presented during pursuit is mislocalized in the direction of the pursuit. Although this has been explained by a temporal mismatch between the slow visual processing of flash and fast efferent signals on eye positions, here we show that spatial contexts also play an important role in determining the flash position. We put various continuously lit objects (walls) between v...

BACKGROUND Automated function imaging (AFI) is a recently developed method of calculating the longitudinal peak systolic strains (LS) of the regional left ventricular (LV) wall using speckle tracking echocardiography and displaying them on a single bull's-eye map. The feasibility of AFI in patients with regional LV wall motion abnormalities caused by myocardial infarction (MI) was evaluated by ...

BACKGROUND We sought to use computed tomography (CT) data to support the correct differential diagnosis of patients with spontaneous intramural hematomas of the gastrointestinal tract, to aid in the clinical management of those using oral anticoagulants. METHODS Patient data were retrospectively analyzed and patients were divided into two groups. The first group contained 10 patients (5 femal...

Packed-bed single-tank thermocline system with reduced cost is an alternative to the conventional two-tank for thermal energy storage. This work systematically explores wall impact on behavior of packed-bed tanks. For this purpose, adapted transient models were developed and fully exploited first time. Two tank configurations investigated compared: a high-temperature pilot-scale steel low-tempe...

PURPOSE To compare the fits of normal-tissue complication probability (NTCP) models based on rectal dose-wall histograms (DWHs) vs. dose-volume histograms (DVHs) when the two are used to analyze a common set of late rectal toxicity data. METHODS AND MATERIALS Data were analyzed from 128 prostate cancer patients treated with 3-dimensional conformal radiotherapy (3D-CRT) at The University of Te...

one of the most important goals of sugar beet cultivation is to achieve high seedling emergence and establishment under water deficit conditions. in this experiment irrigation of the seed bearing plants was cutoff in four periods of 750, 1000, 1250 and 1500 gdd after schtechlings were planted and the seeds were formed and grown under water stress. the experiment was carried out as a randomized ...

Operator cutoff regularization based on the original Schwinger's proper-time formalism is examined. By constructing a regulating smearing function for the proper-time integration, we show how this regularization scheme simulates the usual momentum cutoff prescription yet preserves gauge symmetry even in the presence of the cutoff scales. Similarity between the operator cutoff regularization and...

In hydraulic structures design, using cutoff walls is essential to reduce and control the resultant uplift force (U), seepage discharge (Q), exit gradient (i). This research investigates effectiveness of inclined double under structures, considering influence depths, locations, inclination angles upstream downstream by Finite Element Method (FEM). The results confirmed that installing a deeper ...
