Purpose: Qat chewing, smoking, smokeless tobacco (locally known as shammah) and waterpipe smoking (locally known as madaah) are common habits in Yemen. The aim of this study was to investigate the prevalence of oral cancerous and precancerous lesions, and to investigate the prevalence of oral risk habits among Yemeni adults attending outpatient dental clinics, Sana‘a University. Materials and m...

Question Answering (QA) is a task that entails reasoning over natural language contexts, and many relevant works augment models (LMs) with graph neural networks (GNNs) to encode the Knowledge Graph (KG) information. However, most existing GNN-based modules for QA do not take advantage of rich relational information KGs depend on limited interaction between LM KG. To address these issues, we pro...

Pain of the tempro-mandibular joint (TMJ) has a direct bearing to missing teeth and excessive physical activity. Consumption of qat requires chewing on the leaves to extract their juice for long hours. A 65-year-old male Yemeni patient, a Qat chewer, reported to the university dental hospital at King Khalid University complaining of pain in left temporomandibular joint with missing mandibular a...

Rhizobium leguminosarum bv. viciae 3841 contains six putative quaternary ammonium transporters (Qat), of the ABC family. Qat6 was strongly induced by hyperosmosis although the solute transported was not identified. All six systems were induced by the quaternary amines choline and glycine betaine. It was confirmed by microarray analysis of the genome that pRL100079-83 (qat6) is the most strongly...

The effect of a common habit among Yemeni population on the periodontal status was investigated. This cross-sectional study was done on 2500 Yemenis with mean age 27.01 years (1818 males and 682 females). Among these 1528 were qat chewers and 972 were non-chewers. Detailed questionnaire and pre-designed scoring system for the periodontal status were employed for each case. Study results indicat...

Service providers of satellite imagery provide large quantities of orthorectified and co-registered products. The customer usually has no means of checking the quality of the product that he receives and the providers themselves usually do not deliver detailed reports about the quality of their products. In this paper, we describe the development of quality assessment methods and associated too...

AbstractDeep neural network quantization with adaptive bitwidths has gained increasing attention due to the ease of model deployment on various platforms different resource budgets. In this paper, we propose a meta-learning approach achieve goal. Specifically, MEBQAT, simple yet effective way bitwidth-adaptive quantization-aware training (QAT) where is effectively combined QAT by redefining tas...

En este trabajo se elaboraron películas comestibles (PCs) a base de quitosano (Q), agar (A) y tomillo (T), en cuatro diferentes formulaciones (Q, A, QA QAT). A las PCs les evaluaron propiedades mecánicas (tensión elongación la ruptura), estructurales (espectroscopía infrarrojo por FTIR), térmicas (análisis termogravimétrico), transporte (permeabilidad al vapor agua) análisis morfológico (micros...
