Background & objectives: Coronaviruses are a large group of viruses and constitute a subfamily of Coronaviridae ranging from the common cold virus to viruses causing more acute diseases such as SARS (Severe Acute Respiratory Symptom), MERSE (Middle East Respiratory Symptom) and COVID-19 inflicting human respiratory system. The aim of this study was to evaluate the trend of changes in the clinic...

AIM The aim of this study was to evaluate the haemodynamic correlates of heart sound (HS) parameters such as third HS (S3), first HS (S1), and HS-based systolic time intervals (HSTIs) from an implantable cardiac device. METHODS AND RESULTS Two unique animal models (10 swine with myocardial ischaemia and 11 canines with pulmonary oedema) were used to evaluate haemodynamic correlates of S1, S3,...

A new method for feature extraction based on FPGA (Field Programmable Gate Arrays) implementation is proposed in this paper. The specific application is offline Farsi handwritten digit recognition. The classification is based on a simple two layer MLP (Multi Layer Perceptron). This method of feature extraction is appropriate for FPGA implementation as it can be implemented only with addition an...

BACKGROUND Tuberculous meningitis (TBM) and herpes simplex encephalitis (HSE) are common neurological diseases involving the brain parenchyma, and both can result in chronic epilepsy. Here, we identified possible variables affecting the prognosis of central nervous system (CNS) infection-related epilepsy. METHODS The clinical seizure characteristics and demographic data of 20 TBM- and 55 HSE-...

Characterization of humic substances (HS) in environmental samples generally involves labor-intensive and time-consuming isolation and purification procedures. In this paper, the development of an automated system for HS isolation and purification is described. The novelty of the developed system lies in the way the multiple liquids and columns used in the isolation/purification procedure are h...

In this paper a new Farsi/Arabic numeral recognition system, based on the combination of structural and statistical classifiers, is presented. The structural method cannot deal with broken characters well. A statistical classifier would be more suitable for these unconnected samples. Thanks to the combination of structural and statistical approaches, a complete description of the characters can...

The adaptive-subspace self-organizing map (ASSOM) proposed by Kohonen is a recent development in self-organizing map (SOM) computation. In this paper, we propose a method to realize ASSOM using a neural learning algorithm in nonlinear autoencoder networks. Our method has the advantage of numerical stability. We have applied our ASSOM model to build a modular classification system for handwritte...

Thirty-two Afshari lambs were used in a completely randomized design with a 2 × 2 factorial arrangement of treatments to evaluate a nutritional supplement designed to provide multiple gluconeogenic precursors during heat stress (HS). Lambs were housed in thermal neutral (TN) conditions and fed ad libitum for 8 d to obtain covariate data (period 1 [P1]) for the subsequent experimental period (pe...

In the past two decades, China’s manufacturing exports have grown spectacularly, U.S. imports from China have surged, but U.S. exports to China have increased only modestly. Using representative, longitudinal data on individual earnings by employer, we analyze the effect of exposure to import competition on earnings and employment of U.S. workers over 1992 through 2007. Individuals who in 1991 ...
