Despite significant advances in diagnosis and treatment, the prognosis of esophageal adenocarcinoma remains poor highlighting the importance of early detection. Although white light (WL) upper endoscopy can be used for screening of the esophagus, it has limited sensitivity for early stage disease. Thus, development of new imaging technology to improve the diagnostic capabilities of upper GI end...
The emergence of the novel SARS-CoV2 virus, proclaimed by World Health Organization (WHO) as a culpable agent for pandemic situation, caught scientific and medical communities off guard. One most common complications following pulmonary disease is represented gastrointestinal (GI) disorders, especially ischemic damage. Inflammation, vasculopathy, immobility, endothelial dysfunction, hypercoagul...
Introduction: White spot syndrome virus (WSSV) is one of the most deadly infectious pathogens of the shrimp culture industry. Neither effective vaccines nor efficient treatments are currently available for this disease. Vibrio species are well known dominant bacterial pathogens in the shrimp ponds. As facultative pathogenic bacteria, it is possible that Vibrio spp. along with WSSV to co-infect ...

VOLUME CHANGES IN THE LUNG are the basis for life-sustaining respiration, yet in many regards, the lung is overengineered and the mechanical limits are most often not approached (11). For some activities, however, the entire volume range of the thorax and lung is necessary; for example, consider childbirth. But what determines the extreme limits of lung volume? Common wisdom (14, 15, 17, 20) ho...
Abstract Background Corona virus disease 2019 (COVID-19) pandemic—as declared by the World Health Organization—is a major threatening public health problem. At time of writing, more than 60,000,000 patients and 1,500,000 deaths were recorded worldwide. Besides classical chest symptoms, gastrointestinal tract-related symptoms noted, like diarrhea, abdominal distention, hematochezia, adding diffi...
あらまし サイクリックプレフィックス (CP)を用いたブロック伝送では,CPの付加及び除去を含めた通信路 が巡回行列で記述されるが,ガード時間 (GI) を超える遅延波が存在する場合などには巡回行列の一部の成分が 欠落した行列(不完全巡回行列)による信号ひずみが観測される.本論文では,CP を用いたブロック伝送方式, 特にシングルキャリヤのブロック伝送 (SC-CP) 方式を対象に,不完全巡回行列による信号ひずみを少ない要求 演算量で補償する手法を提案する.提案方式では,新たに導出したMMSE (Minimum Mean-Square-Error)基 準離散周波数領域等化器重みとその等化器出力信号の信頼度の違いを利用した擬似逆行列による等化器によって, 不完全巡回行列による信号ひずみを巡回行列による信号ひずみに変換することで,従来からの離散周波数領域等 化器を利用可能にする.計算機シ...
The effect of magnetic field on the growth of bacteria was studied with the series piezoelectric quartz crystal (SPQC) sensing technique. The growth situations of Escherichia coli (E. coli) in the absence and presence of different intensities of static magnetic fields were examined and analyzed. The results showed that the growth of E. coli was inhibited due to the presence of magnetic fields. ...
