As NAND Flash memory process technology scales below 32nm and the number of charge levels per cell exceeds four, cell threshold voltage distributions must be narrower in order to prevent errors resulting from distribution overlap [3, 5, 6]. An obstacle to achieving narrow distributions is the floating-gate (FG) to floating-gate coupling [4, 6]. This coupling shifts the threshold voltages by a d...

We construct a medical X-ray direct digital radiography (DDR) system based on a CCD (charge-coupled devices) camera. For the original images captured from X-ray exposure, computer first executes image flat-field correction and image gamma correction, and then carries out image contrast enhancement. A hybrid image contrast enhancement algorithm which is based on sharp frequency localization-cont...

The present study attempts to uncover language teachers’ beliefs about oral corrective feedback. It also explores the role of teachers’ experiences in their choice of error correction techniques. To achieve the purpose of the study, 137 foreign language teachers were asked to fill out the developed questionnaire and follow-up interviewed were conducted with 10 teachers, five novice and experien...

We measured the concentration of erythrocyte protoporphyrin in 43 blood samples by two fluorometric methods. In the indirect method, protoporphyrin was extracted from blood and the fluorescence of the free acid in the extract was determined with a filter-fluorometer. These results were compared with results of direct determination of protoporphyrin in the same samples. In the direct assay the f...

Thank you very much for publishing our manuscript entitled: "Quantification and comparison of bone-specific alkaline phosphatase with two methods in normal and paget's specimens" in the latest issue of the journal (Caspian Journal of Internal Medicine, Summer 2012 3(3):478-483). Unfortunately, we noticed the mistake in the date of our study after its publication in your latest revised manuscrip...

Testing two-port memories requires the use of single-port tests as well as special two-port tests; the test strategy determines which tests have to be used. Many two-port memories have ports which are read-only or write-only; this impacts the possible tests for single-port and two-port memories, as well as the test strategy. This paper discusses the consequences of the port restrictions (read-o...

Anomalous pulmonary venous connections were found in seven (0.6%) of 1183 patients with tetralogy of Fallot. Three patients had totally anomalous connections (one supracardiac, one direct to coronary sinus, and one mixed supracardiac and infracardiac) and four patients had partially anomalous pulmonary venous connections. All patients presented with the clinical features of tetralogy of Fallot....

The aim of this paper is to present and analyze a new direct method for solving the linear elasticity inverse problem. Given measurements some displacement fields inside medium, we show that stable reconstruction elastic parameters possible, even discontinuous without boundary information. We provide general approach based on weak definition stiffness-toforce operator which conduces see problem...
