The high computation and memory storage of large deep neural networks (DNNs)models pose intensive challenges to the conventional Von-Neumann architecture,incurring substantial data movements in the memory hierarchy. The memristorcrossbar array has emerged as a promising solution to mitigate the challengesand enable low-power acceleration of DNNs. Memristor-based weight pruning andweight quantization have been seperately investigated and proven effectivenessin reducing area and power consumption compared to the original DNN model.However, there has been no systematic investigation of memristor-basedneuromorphic computing (NC) systems considering both weight pruning and weightquantization. In this paper, we propose an unified and systematicmemristor-based framework considering both structured weight pruning and weightquantization by incorporating alternating direction method of multipliers(ADMM) into DNNs training. We consider hardware constraints such as crossbarblocks pruning, conductance range, and mismatch between weight value and realdevices, to achieve high accuracy and low power and small area footprint. Ourframework is mainly integrated by three steps, i.e., memristor-based ADMMregularized optimization, masked mapping and retraining. Experimental resultsshow that our proposed framework achieves 29.81X (20.88X) weight compressionratio, with 98.38% (96.96%) and 98.29% (97.47%) power and area reduction onVGG-16 (ResNet-18) network where only have 0.5% (0.76%) accuracy loss, comparedto the original DNN models.

Relations between the Sultanate of Oman and the Islamic Republic of Iran extend back to the ancient civilisations that inhabited both regions. At first, trade was the only connection between the two countries. This later evolved into the Persian occupation of Oman which ended in the first century BC after the battle of Saloot. However, these ancient relations are irrelevant to this paper which seeks to examine the nature of the relations between the two states in current times. Oman recognizes Iran as an ancient civilization, not just a new or modernized state. Oman does not ignore the role of Iran in the region and gives it its deserved attention. This is because Oman understands Iran’s significant contemporary and historical position in the Middle East.It is undoubted that Omani influence reached the Iranian territories through the message of Islam. This was the result of Omani merchants and travelers who sailed through the golden strait(Hormuz) to the Iranian border. Moreover, some Persian and Arab tribes settled in the north cost of Oman and lived peacefully together till the modern days. Oman-Iran’s relationship is based on reciprocal respect and not interfering in the internal affairs of both states. The security and logistic cooperation between the two states was very strong in the 1970s and reached its peak in 1977, when the Shah of Iran visited Oman. In the 1970s, Oman signed several agreements, many of which were with Iran, to secure itself from communist threats.

It is common knowledge that one of the methods of political alliance was through marriage, since the ancient times were the tribes to hold links between them through mating and proportion, and was close to the relationship and marital relationship at the time of the most important relations, once a man marry from a tribe to be considered a member of that tribe, And it is protected by its strength, and the tribe feels naturally that they have to support it and cooperate with it. This phenomenon continued even after the advent of Islam. This era witnessed many masrhas. The most prominent of these were the Mazra'at al-Bayt al-'Aliya, with other ablutions, especially the marriage of Imam al-Jawad (peace be upon him) from the daughter of Al - Ma'moun Abbasid.

Objective The objective of this study was to evaluate the effect of decreasing renal function on left ventricular mass index (LVMI) in children with chronic kidney disease (CKD) on regular hemodialysis attending Assiut University Hospital for Children, and also to evaluate left ventricular mass changes as predictor of morbidity and mortality of uremic children by using echocardiography, aiming to use it in the future. Patients and methods Baseline clinical characteristics were collected by careful history and examination. Routine laboratory methods were used to measure biochemical parameters: hemoglobin, C‑reactive protein, phosphorus, calcium, parathyroid hormone, and lipid profile after patients fasted for 8 h. Echocardiographic parameters were measured within 2–24 h after a dialysis session. Results In this study, we studied 36 children on regular hemodialysis. The age of our patients ranged from 3.5 to 16 years, and the number of male patients was similar to female patients. In our study. we found eccentric left ventricular hypertrophy was predominant (38.9%) compared with concentric left ventricular hypertrophy (13.9 %). We found that 52.8% of patients had increased LVMI and 47.2 % had normal LVMI. Regarding the fate of our cases, 39% died during the study period, whereas the other 61% survived. Mortality among patients with increased LVMI was higher (28 %) than among patients with normal LVMI (11 %). Conclusion Children with CKD are prone to development of cardiac dysfunctions, so early and regular echocardiographic studies of all children with CKD to detect early cardiac changes and institute interventions and follow‑up are required.

Background Hepatocellular carcinoma (HCC) is a common worldwide cancer. α‑Fetoprotein (AFP) is a routinely used biomarker for HCC diagnosis, but with reduced clinical applicability due to low sensitivity and specificity. Dickkopf‑1 (DKK‑1) is vital in the differentiation, survival, apoptosis, and cell death. DKK‑1 has a potential oncogenic role in carcinogenesis. Aim In this study, we evaluated the diagnostic and prognostic performance of serum DKK‑1, AFP, and their combination in HCC. Patient and methods This study was done on 40 HCC patients, 24 liver cirrhosis patients, and 16 age‑matched and sex‑matched healthy controls. The patients were selected from the Tropical Medicine and Gastroenterology Department, Al‑Rajhi Liver Hospital. Results The optimum cutoff for DKK‑1 in HCC patients versus liver cirrhosis and control groups was more than 331 pg/ml with a sensitivity of 80.0% and specificity of 87.5%. The optimum cutoff for AFP was more than 8 IU/ml (sensitivity 77.5%, specificity 85.0%).The combination of the two markers had the best sensitivity (92.5%) in the diagnosis of HCC patients. Conclusion DKK‑1 levels was significantly higher in newly diagnosed HCC patients than in the nonmalignant control group. The combination of the two markers (DKK‑1 and AFP) enhanced the sensitivity.

In this research, a study of the behavior and correlation between sunspot number (SSN) and solar flux (F10.7) have been suggested. The annual time of the years (2008-2017) of solar cycle 24 has been adopted to make the investigation in order to get the mutual correlation between SSN) and F10.7. The test results of the annual correlation between SSN & F10.7 is simple and can be represented by a linear regression equation. The results of the conducted study showed that there was a good fit between SSN and F10.7 values that have been generated using the suggested correlation equation and the observed data."

This study aimed to detect atherosclerotic changes in the carotid arteries of systemic lupus erythematous (SLE) patients as an indicator of cardiovascular risk factors and to correlate the findings with disease severity and activity parameters as well as to study specific ECG changes in these patients to elucidate possible associations between these variables. Patients and methods This study included 30 SLE patients who met the Systemic Lupus International Collaborating Clinics (SLICC) criteria (group I), 30 rheumatoid arthritis (RA) patients diagnosed according to the American College of Rheumatology/European league against rheumatism (EULAR) 2010 criteria (group II), and 30 apparently healthy volunteers age and sex matched to the SLE patients’ group (group III). All patients were subjected to full history taking, thorough clinical examination, assessment of disease activity using the Systemic Lupus Erythematous Disease Activity Index (2 K) score and assessment of damage by the SLICC/American College of Rheumatology Damage Index (SDI). Laboratory investigations included: complete blood count, erythrocyte sedimentation rate, lipid profile, immunological profile (antinuclear antibodies, anti-double-stranded DNA antibody, anticardiolipin antibody, and complements C3 and C4). The right common carotid artery was scanned by ultrasound and the average of carotid intima media thickness (CIMT) was calculated (mean of four readings) for all participants participating in the study. ECG was also done for all participants. Results The mean CIMT was higher in RA patients (0.71±0.194 mm) with a nonsignificant difference compared with SLE patients (0.68±0.197 mm) and a high statistically significant difference (P0.05). Abnormal ECG findings were observed in 3/30 SLE patients (10%), 10/30 RA patients (33.3%), and one/30 healthy control (3.3%), with statistically significant difference (P<0.03) among groups. The presence or absence of abnormal ECG findings showed statistically insignificant differences regarding patients’ disease activity and mean CIMT. Conclusion Although ECG changes were present in 10% of our SLE patients, association of specific ECG changes could not be confirmed. A greater prevalence of increased CIMT was observed in SLE patients, emphasizing the important role of this disease in the development of premature atherosclerosis which did not correlate with disease activity or severity parameters.

One of the most challengeable problems in pattern recognition domain is financial time series forecasting which aims to exactly estimate the cost value variations of a particular object in future. One of the best well-known financial time series prediction methods is Neural Network (NN) but it suffers from parameter tuning such as number of neuron in hidden layer, learning rate and number of periods that should be forecasted. To solve the problem, this paper proposes a new metaheuristic-based parameter tuning scheme which is based on Harmony Search (HS). To improve the exploration and exploitation rates of HS, the control parameters of HS are adapted during the generations. Evaluation of the proposed method on several financial times series datasets shows the efficiency of the improved HS on parameter setting of NN for time series prediction.
