Cardiac tamponade from a giant thymoma: case report

Thymoma, the most common neoplasm of the anterior mediastinum especially in adults, accounts for 20-25% of all mediastinal tumors and 50% of anterior mediastinal masses. These tumors are routinely asymptomatic for prolonged periods of time. Pericardial tamponade is a very rare initial manifestation of a thymoma. This report presents a patient who had hemorrhagic pericardial tamponade that likely resulted from the largest symptomatic mixed type (type AB) thymoma described in the literature

Early impact of aortic wrapping on patients undergoing aortic valve replacement with mild to moderate ascending aorta dilatation

<p>Abstract</p> <p>Background</p> <p>The management of mild to moderate dilatation of the ascending aorta of less than 5 cm is controversial, particularly when concomitant surgical correction of aortic valve is required. We investigate the impact of a simple method of aorta reduction using Dacron graft wrapping during aortic valve replacement on the rest of the aorta.</p> <p>Methods</p> <p>We studied 14 patients who had ascending aorta dilatation of 4-5 cm before undergoing aortic wrapping during their aortic valve replacement and compared with their post-operative imaging within a month.</p> <p>Results</p> <p>The diameters of the ascending aorta wrapped with the Dacron graft were significantly reduced within 4 weeks after surgery from 44.7 ± 2.6 to 33.6 ± 3.9 mm (p < 0.001). This was associated with significant reduction in the diameter of rest of ascending aorta: coronary sinuses (from 37.9 ± 4.9 mm to 33.3 ± 6.1 mm; p < 0.001), sinotubular junction (from 33.2 ± 4.7 mm to 30.6 ± 4.4 mm, p = 0.02), and aortic arch (from 34.7 ± 4.3 mm to 32.6 ± 4.1 mm, p = 0.03).</p> <p>Conclusions</p> <p>Reduction of ascending aortic dilatation by wrapping with a Dacron graft in this preliminary study is associated with favourable early reversed aortic remodelling. This supports the hypothesis that correction of mild-moderate dilatation of the ascending aorta with Dacron wrapping at the time of aortic valve surgery may prevent the progression of the dilatation, although the long-term study on a larger population is needed to confirm its benefits.</p

Predictive Maintenance Analysis for Industries

IEEE Communications SocietyIn this paper, we are focused on deriving conclusions from sensor parameter data that would enable the detection of potential faults and the prediction of failures. We used Random Forest, Decision Tree, Naive Bayes, Logistic Regression, Support Vector Machine, and Long Short-Term Memory models to predict faults for sensor data. This analysis, which predicts the failure, has been examined through the pump sensor dataset from Kaggle. It is a binary classification problem, and it performs time series analysis using historical pump sensor data to predict future observations and classify them into a positive label (normal) or a negative label (broken). The pump system must be in perfect condition to ensure continuous power supply. A failure of one of the pumps in the system can lead to a temporary drop in power generation and even a complete outage. This may be avoided if failures are predicted in advance. Therefore, it is important to anticipate failure early to avoid large financial losses. Predictive maintenance is beneficial for industries to prevent these faults and losses. Despite expectations, the Random Forest algorithm outperforms LSTM, followed by Decision Trees. Support Vector Machine and Naive Bayes algorithms show inferior performance compared to Random Forest and LSTM. © 2024 IEEE

Big Data Platform Development With a Domain Specific Language for Telecom Industries

This paper introduces a system that offer a special big data analysis platform with Domain Specific Language for telecom industries. This platform has three main parts that suggests a new kind of domain specific system for processing and visualization of large data files for telecom organizations. These parts are Domain Specific Language (DSL), Parallel Processing/Analyzing Platform for Big Data and an Integrated Result Viewer. In addition to these main parts, Distributed File Descriptor (DFD) is designed for passing information between these modules and organizing communication. To find out benefits of this domain specific solution, standard framework of big data concept is examined carefully. Big data concept has special infrastructure and tools to perform for data storing, processing, analyzing operations. This infrastructure can be grouped as four different parts, these are infrastructure, programming models, high performance schema free databases, and processing-analyzing. Although there are lots of advantages of Big Data concept, it is still very difficult to manage these systems for many enterprises. Therefore, this study suggest a new higher level language, called as DSL which helps enterprises to process big data without writing any complex low level traditional parallel processing codes, a new kind of result viewer and this paper also presents a Big Data solution system that is called Petaminer. © 2013 IEEE

DISKRIMINASI RAS DALAM LA PUTAIN RESPECTUEUSE KARYA JEAN PAUL SARTRE

ABSTRAKPenelitian ini berjudul ?Diskriminasi Ras Dalam La Putain RespectueuseKarya Jean Paul Sartre? yang akan mengkaji tentang diskriminasi ras antara kelompok kulit putih dan kelompok kulit hitam. Tujuan penelitian ini adalah untuk menjelaskan pengaruh eksistensi tokoh La Putainterhadap masalah diskriminasi dalam drama ini.Peneliti menggunakan teori penokohan sebagai teori intrinsik sastra untuk mengidentifikasikan tokoh-tokoh dalam drama. Teori ekstrinsik yang digunakan adalah eksistensialisme sebagai penunjang guna meneliti eksistensi tokoh La Putain. Data didapatkan dalam drama La Putain Respectuese.Hasil analisis dari penelitian ini akan memperlihatkan bahwa manusia terbagi dalam beberapa kelompok ras. Meskipun telah hidup pluralisme, namun dalam beberapa praktek kehidupan manusia masih membawa nama ras, rasisme atau rasialisme. Diskriminasi ras yang sering terjadi dipengaruhi oleh eksistensi manusia yangmenonjol dan manusia lain yang menjadi pasif. Namun ada satu di antaranya yang berusaha menjadi penengah dalam konflik yang terjadix + 119 hlm
