Semantic Clustering of Search Engine Results
This paper presents a novel approach for search engine results clustering that relies on the semantics of the retrieved documents rather than the terms in those documents. The proposed approach takes into consideration both lexical and semantics similarities among documents and applies activation spreading technique in order to generate semantically meaningful clusters. This approach allows documents that are semantically similar to be clustered together rather than clustering documents based on similar terms. A prototype is implemented and several experiments are conducted to test the prospered solution. The result of the experiment confirmed that the proposed solution achieves remarkable results in terms of precision
Impact of feature extraction techniques on classification accuracy for EMG based ankle joint movements
EMG based control becomes the core of the pros-theses, orthoses and rehabilitation devices in the recent research. Though the difficulties of using EMG as a control signal due to the complexity nature of this signal, the researchers employed the pattern recognition technique to overcome this problem. The EMG pattern recognition mainly consists of four stages; signal detection and preprocessing feature extraction, dimensionality reduction and classification. However, the success of any pattern recognition technique depends on the feature extraction and dimensionality reduction stages. In this paper time domain (TD) with 6th order auto regressive (AR) coefficients features and three techniques of dimensionality reduction; principal component analysis (PCA), uncorrelated linear discriminant analysis (ULDA) and fuzzy neighborhood preserving analysis with QR decomposition (FNPA-QR) were demonstrated. The EMG data were recorded from the below knee muscles of ten intact-subjects. Four ankle joint movements are classified using three classifiers; LDA, k-NN and MLP. The results show the superiority of TD&6th AR with FNPA-QR and k-NN combination with (96.20% ± 4.1) accuracy

PREVALENCE OF RUBELLA IGG ANTIBODIES AMONG PRODUCTIVE-AGE WOMEN IN AL-MAHWEET GOVERNORATE, YEMEN
Background: Rubella is an infectious viral disease that caused by the Rubella virus. The incidence of rubella infection in women during pregnancy leads to complications for fetus development and cause congenital rubella syndrome or fetal death. This study aimed to determine the prevalence rate of rubella among reproductive-age women in Al-Mahweet, Yemen.
Methods: A cross sectional study was conducted among females attending healthcare centers and schools from July 2007 to June 2008. Blood samples were collected individually from 270 females aged 15-35 years and the rubella virus IgG antibody was quantitated by enzyme-linked immunosorbent assay (ELISA). The needed data were collected by using a pretested questionnaire and analyzed by statistical program.
Results: Overall, 197(73%) had IgG-positive antibody to rubella and 73(27%) had IgG-negative antibody to rubella. The highest rate of anti-rubella IgG was among females aged 15-25 years and the lowest was among the females aged 31-35 years. Similarly, the higher rate was among females living in urban area compared to females from rural area. The statistically significant difference was found between most educational levels and positive results of anti-rubella IgG. With regard to marital status, the most frequent of rubella antibody was 72.3%, 73.1%, and 75.0%, respectively, recorded among single, married, and divorced females. The non-pregnant women had (73.7%) more incidence to rubella IgG antibody than pregnant (66.7%). 82.2% of IgG- positive women had no history of stillbirth and 65% had a history of stillbirth.
Conclusions: Most of the enrolled females had immunity against rubella virus, but still a significant percentage were susceptible to rubella infection. Thus, it is essential to introduce of rubella vaccine to control and prevent the rubella virus circulating among the community.

Fatty infiltration of the pancreas: a systematic concept analysis
Fatty infiltration of the pancreas (FIP) has been recognized for nearly a century, yet many aspects of this condition remain unclear. Regular literature reviews on the diagnosis, consequences, and management of FIP are crucial. This review article highlights the various disorders for which FIP has been established as a risk factor, including type 2 diabetes mellitus (T2DM), pancreatitis, pancreatic fistula (PF), metabolic syndrome (MS), polycystic ovary syndrome (PCOS), and pancreatic duct adenocarcinoma (PDAC), as well as the new investigation tools. Given the interdisciplinary nature of FIP research, a broad range of healthcare specialists are involved. This review article covers key aspects of FIP, including nomenclature and definition of pancreatic fat infiltration, history and epidemiology, etiology and pathophysiology, clinical presentation and diagnosis, clinical consequences, and treatment. This review is presented in a detailed narrative format for accessibility to clinicians and medical students
Characteristics and predictors of progression in an Egyptian multiple sclerosis cohort: a multicenter registry study
Imaging of pleural disease
The pleural space is a "potential" anatomical space which is formed of two layers: visceral and parietal. It normally contains a trace of fluid (∼10 mL in each hemithorax). Diseases of the pleura can manifest with thickening of the pleural membranes or by abnormal accumulation of air or liquid. Chest radiographs are often the first imaging tests to point to a pleural pathology. With the exception of pneumothorax, and due to the inherent limitations of chest radiographs, ultrasound and/or computed tomography are usually required to further characterise the pleural pathology and guide management. This review summarises the utility of different imaging tools in the management of pleural disease and discusses new and evolving tools in imaging of the pleura
