Бокс в Томском Политехническом университете
Это первая книга о боксе в одном из томских университетов. События, факты, рассказы о боксёрах и их тренерах основаны на документальных материалах, в том числе из архивных источников, воспоминаниях ветеранов и действующих спортсменов. Это знак благодарности и признания боксёрам, тренерам и спортивным организаторам за их нелёгкую, но благодарную работу, за популяризацию бокса. В результате работы получилась содержательная и увлекательная книга, которая вызовет несомненный интерес у читателей, и будет способствовать популяризации такого замечательного вида единоборств как бокс
An objective validation of polyp and instrument segmentation methods in colonoscopy through Medico 2020 polyp segmentation and MedAI 2021 transparency challenges
Automatic analysis of colonoscopy images has been an active field of research
motivated by the importance of early detection of precancerous polyps. However,
detecting polyps during the live examination can be challenging due to various
factors such as variation of skills and experience among the endoscopists, lack
of attentiveness, and fatigue leading to a high polyp miss-rate. Deep learning
has emerged as a promising solution to this challenge as it can assist
endoscopists in detecting and classifying overlooked polyps and abnormalities
in real time. In addition to the algorithm's accuracy, transparency and
interpretability are crucial to explaining the whys and hows of the algorithm's
prediction. Further, most algorithms are developed in private data, closed
source, or proprietary software, and methods lack reproducibility. Therefore,
to promote the development of efficient and transparent methods, we have
organized the "Medico automatic polyp segmentation (Medico 2020)" and "MedAI:
Transparency in Medical Image Segmentation (MedAI 2021)" competitions. We
present a comprehensive summary and analyze each contribution, highlight the
strength of the best-performing methods, and discuss the possibility of
clinical translations of such methods into the clinic. For the transparency
task, a multi-disciplinary team, including expert gastroenterologists, accessed
each submission and evaluated the team based on open-source practices, failure
case analysis, ablation studies, usability and understandability of evaluations
to gain a deeper understanding of the models' credibility for clinical
deployment. Through the comprehensive analysis of the challenge, we not only
highlight the advancements in polyp and surgical instrument segmentation but
also encourage qualitative evaluation for building more transparent and
understandable AI-based colonoscopy systems
4D treatment planning for scanned ion beams
At Gesellschaft für Schwerionenforschung (GSI) more than 330 patients have been treated with scanned carbon ion beams in a pilot project. To date, only stationary tumors have been treated. In the presence of motion, scanned ion beam therapy is not yet possible because of interplay effects between scanned beam and target motion which can cause severe mis-dosage. We have started a project to treat tumors that are subject to respiratory motion. A prototype beam application system for target tracking with the scanned pencil beam has been developed and commissioned
The Rotterdam Study: 2012 objectives and design update
The Rotterdam Study is a prospective cohort study ongoing since 1990 in the city of Rotterdam in The Netherlands. The study targets cardiovascular, endocrine, hepatic, neurological, ophthalmic, psychiatric, dermatological, oncological, and respiratory diseases. As of 2008, 14,926 subjects aged 45 years or over comprise the Rotterdam Study cohort. The findings of the Rotterdam Study have been presented in over a 1,000 research articles and reports (see www.erasmus-epidemiology.nl/rotterdamstudy). This article gives the rationale of the study and its design. It also presents a summary of the major findings and an update of the objectives and methods
The Generation R Study: design and cohort update 2010
The Generation R Study is a population-based prospective cohort study from fetal life until young adulthood. The study is designed to identify early environmental and genetic causes of normal and abnormal growth, development and health during fetal life, childhood and adulthood. The study focuses on four primary areas of research: (1) growth and physical development; (2) behavioural and cognitive development; (3) diseases in childhood; and (4) health and healthcare for pregnant women and children. In total, 9,778 mothers with a delivery date from April 2002 until January 2006 were enrolled in the study. General follow-up rates until the age of 4 years exceed 75%. Data collection in mothers, fathers and preschool children included questionnaires, detailed physical and ultrasound examinations, behavioural observations, and biological samples. A genome wide association screen is available in the participating children. Regular detailed hands on assessment are performed from the age of 5 years onwards. Eventually, results forthcoming from the Generation R Study have to contribute to the development of strategies for optimizing health and healthcare for pregnant women and children
