Circumferential resection margin and local recurrence after rectal cancer surgery: a population-based study cohort

Aim: Studies have suggested that there is a difference in risk of local recurrence(LR) with circumferential resection margins (CRM) less than 1.0 mm. We aimed toexamine how exact resection margins affect LR risk.Method: Data from the Swedish Colorectal Cancer Registry (SCRCR) were usedfor retrospective analysis of resected rectal cancers between 2005 and 2013. Primaryendpoint was LR.Results: 12146

Circumferential resection margin is a predictor for metastatic disease after rectal cancer surgery: a nation-wide population-based study cohort

Background/Aim To evaluate circumferential resection margin(CRM) as a risk factor for distant metastasis (DM) in rectal cancer.The treatment of rectal cancer has evolved over the last decades.Surgical radicality is the single most important factor in preventingrecurrences, both locally and distantly. CRM B 1.0 mm is consideredto increase recurrence risk. However, not all patients with CRMB 1.0 mm

Intoxication : An Ethnography of Effervescent Revelry

For two decades, Sébastien Tutenges has conducted research in bars, nightclubs, festivals, drug dens, nightlife resorts, and underground dance parties in a quest to answer a fundamental question: Why do people across cultures gather regularly to intoxicate themselves?Vivid and at times deeply personal, this book offers new insights into a wide variety of intoxicating experiences, from the intimate

How to Precisify Quantifiers

I here argue that Ted Sider's indeterminacy argument against vaguenessin quantifiers fails. Sider claims that vagueness entails precisifications, but holds that precisifications of quantifiers cannot be coherently described: they will either deliver the wrong logical form to quantified sentences, or involve a presupposition that contradicts the claim that the quantifier is vague. Assuming (as does

Assessing and grading music in Swedish compulsory schools

In 2011, a new curriculum was implemented in the Swedish comprehensive school, Läroplan för grundskolan samt för förskoleklassen och fritidshemmet, Lgr 11, which meant new syllabi and a new grading system. Students from year 6-9 were to be graded on a scale ranging from A-F (Skolverket, 2020a). The qualifying points each grade signify are then used when applying to upper secondary school and thus

Quiet Eye and Computerized Precision Tasks in First-Person Shooter Perspective Esport Games

The gaze behavior in sports and other applied settings has been studied for more than 20 years. A common finding is related to the “quiet eye” (QE), predicting that the duration of the last fixation before a critical event is associated with higher performance. Unlike previous studies conducted in applied settings with mobile eye trackers, we investigate the QE in a context similar to esport, in w

Energy Efficiency : What Has Research Delivered in the Last 40 Years?

This article presents a critical assessment of 40 years of research that may be brought under the umbrella of energy efficiency, spanning different aggregations and domains-from individual producing and consuming agents to economy-wide effects to the role of innovation to the influence of policy. After 40 years of research, energy efficiency initiatives are generally perceived as highly effective.

Assessing the economic benefits of active transport policy pathways: Opportunities from a local perspective

Combined with concerns about climate change, air pollution and human health, the COVID-19 pandemic has renewed the use of and policy interest in active transport (AT) modes, namely cycling and walking. However, we note a high degree of uncertainty and lack of assessments addressing the economic benefits of AT policies; particularly when they are used as a mix of policies at the local level. This s

Model catalysts studied by x-rays, visible and infrared light

This work is focused on the study of transition metal model catalysts for gas-phase heterogeneous catalysis, studied with light-based in-situ and operando techniques.Metallic model catalysts, such as Palladium (Pd) and Iridium (Ir) single crystals and in minor part deposited Rhodium (Rh), were studied using a combination of x-ray and non x-ray techniques. The aim was to either acquire structural c

Non-uniform PPM and context tree models

The problem of optimizing PPM with the help of different choices of estimators and their parameters for different subsets of nodes in the context tree is considered. Methods of such optimization for Markov chain and context tree models for individual files and over given sets of files are presented, and it is demonstrated that the extension from Markov chain models to context tree models is necess
