Base station cooperative transmission, which is also known as coordinated multi-point (CoMP) transmission, is a promising technique to improve spectrum efficiency in future cellular systems. However, they need large signalling overhead to gather the channel information. In this paper, we consider low feedback user scheduling in downlink coherent CoMP systems exploiting their inherent channel as...

For many years the lung has been considered off-limits for ultrasound. However, it has been recently shown that lung ultrasound (LUS) may represent a useful tool for the evaluation of many pulmonary conditions in cardiovascular disease. The main application of LUS for the cardiologist is the assessment of B-lines. B-lines are reverberation artifacts, originating from water-thickened pulmonary i...

Results 36 patients were included. Among them, 13 (36 %) had grade 3 PGD. EVLWi was significantly higher in the grade 3 PGD group at ICU admission, day one and at day 2. A cut-off value of 14 ml/kg of EVLWi at admission predicts the progression to grade 3 PGD with a sensitivity of 82% and a specificity of 77% and was significantly associated with the need for rescue therapy for severe hypoxemia...

Background: Lung Ultrasound (LUS) has recently become an important method for diagnostic examination and monitoring of lung disease. Many diseases, such as respiratory distress syndrome (RDS), transient tachypnea the newborn (TTNB), pneumonia were diagnosed by chest X-ray, but can now easily be with LUS. LUS many advantages over X-ray including accuracy, reliability, low cost, radiation free, s...

Pulmonary ultrasound is a non-invasive bedside resource that has showed to be useful for the assessment of patients presenting with respiratory insufficiency as well diagnosis several pleural and other pulmonary pathologies. The score (LUS) semi quantitative scale measures loss aeration cause by many pathologic conditions. Our primary objective was describe factors associated death hospitalizat...

Objectives To evaluate the accuracy of a new COVID-19 prognostic score based on lung ultrasound (LUS) and previously validated variables in predicting critical illness. Methods We conducted single-center retrospective cohort development internal validation study Worsening Score (COWS), combination COVID-GRAM (GRAM) LUS. Adult patients admitted to emergency department (ED) were enrolled. Ten ide...

Introduction: It is already well known that infants and children infected with COVID-19 develop mild to moderate forms of the disease, fever oropharyngeal congestion being most common symptoms. However, there are instances when patients claim be experiencing respiratory Because repeated lung examinations required in these situations, non-irradiating imaging techniques preferred. This study’s ob...

While FrameNet does not record the range of semantic relations found in thesaurus-style lexical resources like WordNet, it does provide a number of ways in which lexical units (LUs) can be seen as related to each other. This paper characterizes and motivates the networks of frame-to-frame relations that are being built on FrameNet’s frames, and introduces additional representational mechanisms ...

Bedside lung ultrasound (LUS) is being adopted in ICUs, with a higher diagnostic accuracy for consolidation, interstitial syndrome, pleural effusion, and pneumothorax when compared chest radiography (CXR). Compare the performance of LUS CXR detection pathologic abnormalities critically ill patients ICU, using thoracic computed tomography (CT) as gold standard. Prospective descriptive single-cen...
