BACKGROUND AND PURPOSE Dynamic susceptibility-weighted contrast-enhanced (DSC) magnetic resonance imaging (MRI) is used to identify the tissue-at-risk in acute stroke, but the choice of optimal DSC postprocessing in the clinical setting remains a matter of debate. Using 15O-water positron emission tomography (PET), we validated the performance of 2 common deconvolution methods for DSC-MRI. ME...

This study explores a proposition that individuals with dyslexia develop enhanced peripheral vision to process visual-spatial information holistically. Participants included 18 individuals diagnosed with dyslexia and 18 who were not. The experiment used a comparative visual search design consisting of two blocks of 72 trials. Each trial presented two halves of the display each comprising three ...

SIMECK is a family of 3 lightweight block ciphers designed by Yang et al. They follow the framework used by Beaulieu et al. from the United States National Security Agency (NSA) to design SIMON and SPECK. A cipher in this family with K-bit key and N -bit block is called SIMECKN/K. We show that the security of this block cipher against linear cryptanalysis is not as good as its predecessors SIMO...

A video coding method is proposed which is based upon fractal block coding. The method utilizes a novel three-dimensional partitioning of input frames for which a number of efficient block-matching search methods can be used, and permits spatio-temporal splitting of the input blocks to improve overall-encoding quality. After describing the basic fractal block coding algorithm, the details of th...

An 82-year-old woman was admitted to the hospital due to repeated episodes of syncope with incontinence. Electrocardiography showed torsades de pointes, complete atrioventricular (AV) block, T-wave inversions and a prolonged QTc interval. Urgent coronary angiography showed no significant coronary stenosis and left ventriculography demonstrated typical abnormal wall motion of takotusbo cardiomyo...

Materials and methods: This study was conducted as a randomized complete block design. Treatments were weaning at 12, 15, 18, and 21 days of age (N = 2272 pigs). Each block was an off-site nursery, with four replicates (pens) of each treatment in each of four blocks. All pigs in a block were weaned from a 7300-head sow farm on the same day (Day 0). Each pen was observed for 15 minutes on Days 7...

JPEG encodes a still image through a lossy encoding followed by a lossless entropy encoding. The entropy coding in JPEG is a combination of the runlength coding and a variable-length coding. The entropy encoding employed in JPEG aims to exploit repetition of strings within a block but not across blocks. We propose application of Burrows-Wheeler transformation (BWT) to exploit repetition of stri...

Second-degree atrioventricular (AV) block had not been reported as an early manifestation of adult systemic lupus erythematosus (SLE). An 18-year-old woman of SLE presented with asymptomatic second-degree AV block with 2:1 conduction block on electrocardiogram (ECG) during admission. Serologic tests were negative for anti-Sjögren's syndrome A (anti-SS-A/Ro) and anti-SS-B/La antibodies, but posi...

Many complex diseases are related to genetics, and it is of great interest to evaluate the association between single-nucleotide polymorphisms (SNPs) and disease outcome. The association of genetics with outcome can be modified by covariates such as age, sex, smoking status, and membership to the same pedigree. In this paper, we propose a block entropy method to separate two classes of SNPs, fo...

Block layout dimension prediction is an important activity in many VLSI design tasks (structural synthesis, oorplanning and physical synthesis). Block layout dimension prediction is harder than block area prediction and has been previously considered to be intractable [6]. In this paper we present a solution to this problem using a neural network machine learning paradigm. Our method uses a neu...
