Real-Time Analysis of Correlations Between On-Body Sensor Nodes

The topology of a body sensor network has, until recently, often been overlooked; either because the layout of the network is deemed to be sufficiently static (”we always know well enough where sensors are”), we always know exactly where the nodes are or because the location of the sensor is not inherently required (”as long as the node stays where it is, we do not need its location, just its data”). We argue in this paper that, especially as the sensor nodes become more numerous and densely interconnected, an analysis on the correlations between the data streams can be valuable for a variety of purposes. Two systems illustrate how a mapping of the network’s sensor data to a topology of the sensor nodes’ correlations can be applied to reveal more about the physical structure of body sensor networks

Review on PDCD6 (programmed cell death 6), with data on DNA, on the protein encoded, and where the gene is implicated

Quantum Gravitational Bremsstrahlung, Massless versus Massive Gravity

The massive spin-2 quantum gauge theory previously developed is applied to calculate gravitational bremsstrahlung. It is shown that this theory is unique and free from defects. In particular, there is no strong coupling if the graviton mass becomes small. The cross sections go over smoothly into the ones of the massless theory in the limit of vanishing graviton mass. The massless cross sections are calculated for the full tensor theory.Comment: 13 pages, 1 figur

Risk behaviours among native and immigrant youths in Switzerland: a cross-sectional study.

Switzerland has been receiving migrants of various origins for more than 50 years. The adoption of risk-taking behaviours among migrant youths is unclear. Moreover, when studied, migrant youths are rarely analysed according to whether they are first or second generation, or just young people with mixed origins. The aim of this study was to assess whether there are any differences between first-and second-generation immigrants, youths of mixed origins and their native peers in Switzerland concerning their engagement in risk behaviours. A total of 5834 youths from eleven post-mandatory schools in the canton of Fribourg (Switzerland) participated in the baseline survey of the GenerationFRee study, a longitudinal study to assess their lifestyle. Participants were divided by gender and by origin into: (a) natives: Swiss-born youths with Swiss-born parents, (b) first-generation migrants: foreign-born youths with foreign-born parents, (c) second-generation migrants: Swiss-born youths with foreign-born parents, (d) mixed-origin youths: Swiss-born youths with one Swiss-born parent and one foreign-born parent. Participants reported personal, family and school information, and attitudes towards eight risk behaviours. All significant variables at the bivariate level were included in a binary logistic regression. The logistic regression showed that, compared with natives, first-and second-generation migrant boys were less likely to misuse alcohol. Boys of mixed origins were similar to migrants, although at the bivariate level they were more exposed to risk behaviours than were migrants. First-and second-generation migrant girls were less likely to misuse alcohol but three times more likely to be excessive Internet users. Girls of mixed origin were more likely to have their parents not living together and reported antisocial behaviours almost twice more often. Our findings expose a lower engagement in risk behaviours among migrants. The migrant status in these two groups is clearly buffered if other control variables are considered. Thus, we can affirm that in the present study, migrants are not a high-risk population or not more at risk than the native group. Mixed origin youths showed higher risk behaviours than natives and migrants. Special attention should be given to this specific group, as they may be more vulnerable during adolescence

On orbits of the automorphism group on a complete toric variety

Let X be a complete toric variety and Aut(X) be the automorphism group. We give an explit description of Aut(X)-orbits on X. In particular, we show that Aut(X) acts on X transitively if and only if X is a product of projective spaces.Comment: 10 pages, 4 figure

Local control and short-term outcomes after video-assisted thoracoscopic surgery segmentectomy versus lobectomy for pT1c pN0 non-small-cell lung cancer.

The aim of this study was to compare short-term outcomes and local control in pT1c pN0 non-small-cell lung cancer that were intentionally treated by video-assisted thoracoscopic surgery (VATS) lobectomy or segmentectomy. Multicentre retrospective study of consecutive patients undergoing VATS lobectomy (VL) or VATS segmentectomy (VS) for pT1c pN0 non-small-cell lung cancer from January 2014 to October 2021. Patients' characteristics, postoperative outcomes and survival were compared. In total, 162 patients underwent VL (n = 81) or VS (n = 81). Except for age [median (interquartile range) 68 (60-73) vs 71 (65-76) years; P = 0.034] and past medical history of cancer (32% vs 48%; P = 0.038), there was no difference between VL and VS in terms of demographics and comorbidities. Overall 30-day postoperative morbidity was similar in both groups (34% vs 30%; P = 0.5). The median time for chest tube removal [3 (1-5) vs 2 (1-3) days; P = 0.002] and median postoperative length of stay [6 (4-9) vs 5 (3-7) days; P = 0.039] were in favour of the VS group. Significantly larger tumour size (mean ± standard deviation 25.1 ± 3.1 vs 23.6 ± 3.1 mm; P = 0.001) and an increased number of lymph nodes removal [median (interquartile range) 14 (9-23) vs 10 (6-15); P < 0.001] were found in the VL group. During the follow-up [median (interquartile range) 31 (14-48) months], no statistical difference was found for local and distant recurrence in VL groups (12.3%) and VS group (6.1%) (P = 0.183). Overall survival (80% vs 80%) was comparable between both groups (P = 0.166). Despite a short follow-up, our preliminary data shows that local control is comparable for VL and VS

Advances in prevention and therapy of neonatal dairy calf diarrhoea : a systematical review with emphasis on colostrum management and fluid therapy

Neonatal calf diarrhoea remains the most common cause of morbidity and mortality in preweaned dairy calves worldwide. This complex disease can be triggered by both infectious and non-infectious causes. The four most important enteropathogens leading to neonatal dairy calf diarrhoea are Escherichia coli, rota-and coronavirus, and Cryptosporidium parvum. Besides treating diarrhoeic neonatal dairy calves, the veterinarian is the most obvious person to advise the dairy farmer on prevention and treatment of this disease. This review deals with prevention and treatment of neonatal dairy calf diarrhoea focusing on the importance of a good colostrum management and a correct fluid therapy
