PurposeA study of real-time adaptive radiotherapy systems was performed to test the hypothesis that, across delivery and institutions, dosimetric accuracy is improved with treatments over non-adaptive in presence patient-measured tumor motion.Methods materialsTen institutions robotic(2), gimbaled(2), MLC(4) or couch tracking(2) used common materials including CT structure sets, motion traces planning protocols create a lung prostate plan. For each trace, plan delivered twice moving...

A novel system for real-time tumor tracking and motion compensation with a robotic HexaPOD treatment couch is described. The approach based on continuous of the in portal images without implanted fiducial markers, using therapeutic megavoltage beam, abdominal breathing optical markers. Based two independently acquired data sets table movements are calculated. principle operation entire prototype detailed first. In second part performance was investigated four-dimensional-phantom capable...

A central aim of Physical Education (PE) is the promotion basic motor competencies ("Motorische Basiskompetenzen" [MOBAK]). These are necessary prerequisites for developing a physically active lifestyle. Valid test instruments needed evaluation effect PE. For this purpose, we developed instrument assessment in first graders. We empirically investigated construct validity MOBAK study (N = 317, M 7.0 years, girls: n 173, boys: 144). The exploratory factor analysis shows two factorial structure...

The purpose of this study is to examine the reciprocal relationship between motor abilities and physical activity mediation effects self-concept in using longitudinal data. We expect that on are rather indirect via direct without involvement ability self-concept. Data was obtained from Motorik-Modul (MoMo) Longitudinal Study which 335 boys 363 girls aged 11–17 years old at Baseline were examined twice a period six years. Physical assessed by MoMo Activity Questionnaire for adolescents,...

AbstractObjective: Coffee is one of the most widely consumed beverages worldwide. Aim this study was to investigate short-term effects espresso coffee on heart rate variability (HRV), a marker vagal activity, in healthy habitual and non-habitual consumers.Methods: Seventy-seven subjects (38 39 consumers, 74% women, mean age 26.97 ± 6.88 years) took part three laboratory sessions randomized order. In condition 1, espresso; 2, decaffeinated 3, warm water. HRV blood pressure were assessed at...

Traditionally, cognitive, motivational and volitional determinants have been used to explain predict health behaviors such as physical activity. Recently, the role of affect in influencing regulating received more attention. Affects internal cues may automatically activate unconscious processes behavior regulation. The aim our study was examine association between activity daily life. In addition, we studied influence habit being physically active on this relationship. An ambulatory...

A central aim of physical education is the promotion basic motor competencies (in German: Motorische Basiskompetenzen; MOBAK), which are prerequisites for children's active participation in sports culture. This article introduces MOBAK-1 test instrument 6- to 8-year-old children and determines construct validity this instrument. In addition, relationship between MOBAK ability (i.e., strength) as well body mass index (BMI), sex, age investigated.We analyzed data 923 first second graders (422...

Imaging sensors capturing the surroundings of an autonomous vehicle are vital for its understanding environment. While thermal infrared cameras promise improved bad weather and nighttime robustness compared with standard RGB cameras, detecting objects, such as persons, in imagery is a tough problem because image resolution quality typically far lower, especially low-cost sensors. Currently, deep learning based object detection frameworks offer impressive performance on high-quality images....

Abstract Background: Although accumulating evidence suggests that motor and cognitive development is interrelated, only a few studies have investigated links between executive function control. Therefore, the present cross‐sectional study examined relationship competences core components of functioning, including inhibitory control, working memory flexibility. Methods: In 89 preadolescent children, were assessed using MOBAK‐5 test battery. Additionally, all participants completed...

(1) Background: The association between actual and perceived motor competence (MC) is one of the underlying mechanisms that influence practice physical activity. This study mainly aimed to analyze structure correlations MC in schoolchildren compare girls boys. (2) Methods: A total 467 fifth sixth graders (43.9% girls, M = 11.26, SD 0.70) participated. Actual were assessed. To examine proposed four factor models, structural equation models (factor analyses, latent correlations, invariance...

ABSTRACTBackground Motor competence (MC) has been recognized as a main goal in Physical Education (PE) and determining element for the promotion of Activity (PA). The interaction between MC PA would be mediated not only by physical factors, but also psychological affective so their study should consider an integral perspective. Evidence suggests that actual perceived motor competence, motivation enjoyment PE classes play important role schoolchildren's practice. However, all schoolchildren...

Two patients are reported with palatal myoclonus, progressive ataxia, and dysarthria, unresponsive to treatment trihexyphenidyl or L-5-hydroxytryptophan. MRI showed enlargement of the inferior olives in one patient, consistent pathology usually associated myoclonus. The syndrome ataxia myoclonus should be distinguished from other ataxias degenerations that affect brainstem cerebellum. Pathology specificity site lesions distinctive.
