BACKGROUND Scientific publications are important for evaluating the achievements of a medical specialty or discipline. Gastroenterology and Hepatology is a medical specialty in great demand in Taiwan, therefore, this study aimed to analyze the Gastroenterology and Hepatology publications from 1993 to 2013 in Taiwan, using the Web of Science (WoS) database. METHODS Scientific publications from...
This paper describes a system for detecting and estimating the properties of multiple travel lanes in an urban road network from calibrated video imagery and laser range data acquired by a moving vehicle. The system operates in several stages on multiple processors, fusing detected road markings, obstacles, and curbs into a stable non-parametric estimate of nearby travel lanes. The system incor...
This article presents the architecture of Junior, a robotic vehicle capable of navigating urban environments autonomously. In doing so, the vehicle is able to select its own routes, perceive and interact with other traffic, and execute various urban driving skills including lane changes, U-turns, parking, and merging into moving traffic. The vehicle successfully finished and won second place in...
In 2005, over 600 clinically diagnosed typhoid fever cases occurred in South Africa, where an outbreak had been previously described in 1993. Case-control and molecular investigations, including Salmonella enterica serovar Typhi (S. Typhi) isolates from that area from 1993, 2005 and later, were undertaken. Controls were significantly older than cases (P=0·003), possibly due to immunity from pre...
Must causal models distinguish default from deviant events? Much recent work on actual causation is conducted within the structural equations framework (Spirtes et al 1993, Pearl 2000), via the notion of a causal model. In standard causal models one sets up a system of variables, allots values to these variables, and connects these variables via structural equations. Menzies (2004, 2007), Hitch...
Bu çalışmada gelişmekte olan ülkelerde doğrudan yabancı yatırım çıkışlarının yurt içi yatırımlara etkisi araştırılmıştır. kapsamda çalışma, 1993-2018 dönemi için yatay kesit bağımlılığını ele alan panel veri analiz yöntemleriyle incelenmiştir. Serilerin durağanlığı; CADF (2007) birim kök testiyle sınanmış ve serilerin birinci farkları alındığında durağan hale geldiği tespit edilmiştir. Seriler ...
HEADINGS Gastric adenocarcinoma. Total gastrectomy. Complications. Digestive fistula. ABSTRACT Background A total gastrectomy is considered a procedure with a high level of complexity, has high complication rates, both local and general, because patients are mostly with clinical conditions and nutritional compromised by disease. Aim To analyse the results and complications of the total gastrect...
This study evaluated the performance of clear sky surface solar radiation (SSR) and its long-term evolution mechanism in second Modern-Era Retrospective Analysis for Research Applications (MERRA-2) East Asia. The results revealed that although MERRA-2 overestimated clearness index SSR, reanalysis performed well northwestern, northern, northeastern, central From 1980 to 2019, SSRs decreased sign...
BACKGROUND Overall declines in human immunodeficiency virus (HIV) mortality may mask patterns for subgroups, and prior studies of disparities in mortality have used area-level vs individual-level socioeconomic status measures. The aim of this study was to examine temporal trends in HIV mortality by sex, race/ethnicity, and individual level of education (as a proxy for socioeconomic status). M...
