The association between body mass, metabolic rates and survival of bank voles
2009
Summary 1Many studies have been performed in an attempt to explain physiological, ecological and evolutionary factors behind inter- and intraspecific variation in basal metabolic rate (BMR) and maximum aerobic metabolic rate (VO2max). However, very little is known about the association between the traits and fitness components in populations of free-living animals. 2We studied the association between body size and the metabolic rates of bank voles Myodes (= Clethrionomys) glareolus and their survival, measured by repeated trappings across 2 years in an isolated, island population. All measured traits (body mass, BM; head width, HW; VO2max and BMR) were significantly repeatable over short (m…
The Geochemistry of Basalt Handaxes from the Lower Palaeolithic Site of Ma‛ayan Baruch, Israel-A Perspective on Raw Material Selection
2014
The Upper Acheulian site of Ma‛ayan Baruch, northern Israel, is primarily known for its exceptionally large assemblage of thousands of flint handaxes. Within this assemblage, a minute collection of basalt handaxes was retrieved as well, representing particular technological choice within the Upper Acheulian. Using geochemistry, we were able to determine that these basalt handaxes were not made from local basalt, but from different sources. Thus, the use of basalt at the site does not represent an ad hoc choice of using local raw material but, rather, a more complex technological choice pertaining to variability in raw material selection in the Lower Palaeolithic Levant.
Aplicación del Estimador de Parámetros de Segmentación por Media-desplazada (EPSM) a las imágenes de satélite de muy alta resolución espacial: Tetuán…
2015
<p>La segmentación de imágenes constituye un paso crucial en el Análisis de Imágenes Basado en Objetos (AIBO). Combinando distintos valores de los parámetros de entrada de los algoritmos de segmentación se obtienen diferentes resultados. En general, los parámetros óptimos seleccionados se determinan mediante interpretación visual; por lo tanto, la definición de las combinaciones óptimas es una tarea considerablemente difícil. En la presente investigación, se propone una herramienta analítica que denominamos Estimador de Parámetros de Segmentación por Media-desplazada (EPSM) aplicada a la selección automatizada de los valores de los parámetros de segmentación en las imágenes de satélit…
Practical Issues on Energy-Growth Nexus Data and Variable Selection With Bayesian Analysis
2018
Abstract Given that the energy-growth nexus (EGN) is short of a complete theoretical base, the production function used therein is typically complemented with numerous variables that characterize an economy. Researchers are often puzzled not only with the selection of variables per se, but also with the variable sources and the various data handlings which become apparent and available only after years of experience in this research field. Thus, this chapter is divided into two distinctive parts: The first part contains an overview of the available data sources for the EGN as well as a succinct selection of advice on data handlings, transformations, and interpretations that could come handy…
Being oneself through time: Bases of self-continuity across 55 cultures
2017
Çalışmada 60 yazar bulunmaktadır. Bu yazarlardan sadece Bursa Uludağ Üniversitesi mensuplarının girişleri yapılmıştır. Self-continuity - the sense that one's past, present, and future are meaningfully connected - is considered a defining feature of personal identity. However, bases of self-continuity may depend on cultural beliefs about personhood. In multilevel analyses of data from 7287 adults from 55 cultural groups in 33 nations, we tested a new tripartite theoretical model of bases of self-continuity. As expected, perceptions of stability, sense of narrative, and associative links to one's past each contributed to predicting the extent to which people derived a sense of self-continuity…
Interference in Dutch–French Bilinguals : Stimulus and Response Conflict in Intra- and Interlingual Stroop
2018
Abstract. In the present manuscript, we investigate the source of congruency effects in a group of Dutch–French bilinguals. In particular, participants performed a color-identification Stroop task, in which both (first language) Dutch and (second language) French distracting color words were presented in colors. The typical finding is impaired responding when the word and color are incongruent (e.g., “red” in blue) relative to congruent (e.g., “red” in red). This congruency effect is observed for both first and second language distracting color words. The current experiment used a 2-to-1 keypress mapping manipulation, which allows one to separate stimulus conflict (i.e., conflict between w…
Leisure time physical activity in individuals with screen-detected type 2 diabetes compared to those with known type 2 diabetes.
2008
Abstract Aims To investigate whether leisure time physical activity (LTPA) characteristics differ between individuals with previously undiagnosed (screen-detected) and those with previously diagnosed (known) type 2 diabetes. Methods A population-based random sample of 1364 (participation rate 61%) men and 1461 (65%) women aged 45–74 years participated in a cross-sectional health examination including an oral glucose tolerance test and physical activity assessment by a self-administered questionnaire. Results Women with screen-detected type 2 diabetes ( n =110) were physically less active than those with known type 2 diabetes ( n =68) with differences in the duration of physical activity ses…
Bone status in adolescents with type 1 diabetes
2010
Aims The aim of the study was to investigate the potential negative impact of type 1 diabetes on bone status of adolescents. Bone status in adolescents with type 1 diabetes was assessed by means of quantitative ultrasound (QUS) and the influence of metabolic control and other diseaserelated and growth variables was analysed. Methods Group I consisted of 99 pubertal (Tanner ≥2) adolescents (49 female), aged 14.3±2.5 years, diabetes duration 4.6±2.3 years. Controls (group II) were 297 children, matched by sex and age, from a healthy population. The influence of glycated haemoglobin (current: HbA1cD; last year’s mean: HbA1cY; whole duration mean: HbA1cT), diabetes duration, percentage of life …
Coronary artery disease: Risk stratification and patient selection for more aggressive secondary prevention.
2017
In patients with stable coronary artery disease, clinical outcomes are predominantly characterized by the consequences of atherosclerosis on the myocardium, but also by complications of atherosclerosis, notably recurrent acute coronary syndrome or stroke. Secondary prevention therapy is therefore key in this patient population. Intensification of secondary prevention therapy is possible, at the price of a therapeutic risk or a high cost, therefore justifying careful selection of patients with a high residual risk and low therapeutic risk. Two lines of therapy can be intensified, independently of each other, namely anti-thrombotics and lipid-lowering agents. Intensification of anti-thromboti…
Real-time flaw detection on a complex object: comparison of results using classification with a support vector machine, boosting, and hyperrectangle-…
2006
We present a classification work performed on industrial parts using artificial vision, a support vector machine (SVM), boost- ing, and a combination of classifiers. The object to be controlled is a coated heater used in television sets. Our project consists of detect- ing anomalies under manufacturer production, as well as in classi- fying the anomalies among 20 listed categories. Manufacturer speci- fications require a minimum of ten inspections per second without a decrease in the quality of the produced parts. This problem is ad- dressed by using a classification system relying on real-time ma- chine vision. To fulfill both real-time and quality constraints, three classification algorit…
