Initial Enlargement in a Markov chain market model
2011
Enlargement of filtrations is a classical topic in the general theory of stochastic processes. This theory has been applied to stochastic finance in order to analyze models with insider information. In this paper we study initial enlargement in a Markov chain market model, introduced by Norberg. In the enlarged filtration, several things can happen: some of the jumps times can be accessible or predictable, but in the original filtration all the jumps times are totally inaccessible. But even if the jumps times change to accessible or predictable, the insider does not necessarily have arbitrage possibilities.
Age affects myosin relaxation states in skeletal muscle fibers of female but not male mice
2018
The recent discovery that myosin has two distinct states in relaxed muscle–disordered relaxed (DRX) and super-relaxed (SRX)–provides another factor to consider in our fundamental understanding of the aging mechanism in skeletal muscle, since myosin is thought to be a potential contributor to dynapenia (age-associated loss of muscle strength independent of atrophy). The primary goal of this study was to determine the effects of age on DRX and SRX states and to examine their sex specificity. We have used quantitative fluorescence microscopy of the fluorescent nucleotide analog 2′/3′-O-(N-methylanthraniloyl) ATP (mantATP) to measure single-nucleotide turnover kinetics of myosin in skinned skel…
Induction of B-cell development in adult mice reveals the ability of bone marrow to produce B-1a cells
2009
AbstractTo study B-cell development from bone marrow (BM), we generated recombination-activating gene 1 (Rag1)–targeted mice lacking mature lymphocytes. B-cell development can be induced in such mice by B cell–specific restoration of a functional Rag1 transcription unit. Follicular and marginal zone B cells populated the spleen when Rag1 expression was permitted. Notably, the peritoneal cavity was dominated by bona fide B-1a cells, as judged by surface markers and functional properties. These BM-derived B-1a cells exhibited a polyclonal VDJ repertoire with substantial N nucleotide insertions. Nevertheless, physiologic frequencies of phosphatidylcholine-specific B cells were detected. Import…
May Measurement Month 2018: an analysis of blood pressure screening results from Spain.
2020
Este artículo se encuentra disponible en la siguiente URL: https://academic.oup.com/eurheartjsupp/article/22/Supplement_H/H119/5898732 En este artículo también participan: Fernando Martínez, Blanca Carreras, Bettina de Berardinis, Thomas Beaney, Anca Chis Ster, Neil R. Poulter, Xin Xia y Luis M. Ruilope. Elevated blood pressure (BP) is the single most important contributing risk factor to the global disease burden, leading to over 10 million deaths each year. In Spain, hypertension (HTN) affects around 20% of the adult population and remains the greatest attributable cause of cardiovascular mortality. May Measurement Month (MMM) is a worldwide initiative aimed at increasing awareness of HTN…
A Community in Life and Death: The Late Neolithic Megalithic Tomb at Alto de Reinoso (Burgos, Spain)
2016
The analysis of the human remains from the megalithic tomb at Alto de Reinoso represents the widest integrative study of a Neolithic collective burial in Spain. Combining archaeology, osteology, molecular genetics and stable isotope analysis (87Sr/86Sr, δ15N, δ13C) it provides a wealth of information on the minimum number of individuals, age, sex, body height, pathologies, mitochondrial DNA profiles, kinship relations, mobility, and diet. The grave was in use for approximately one hundred years around 3700 cal BC, thus dating from the Late Neolithic of the Iberian chronology. At the bottom of the collective tomb, six complete and six partial skeletons lay in anatomically correct positions. …
Sign effect in adolescents: Within‐subject comparison of delay discounting of hypothetical monetary gains and losses
2020
The purpose of this article is to contribute to the research on the sign effect, steeper discounting of gains compared to losses, by offering results from an experiment using a "double-delay" procedure on adolescents. Twenty-four 14-year-old schoolchildren completed a computer-based test consisting of choices of Smaller-Sooner (SS) and Larger-Later (LL) hypothetical monetary gains and losses. Within-subject comparison and analysis of the aggregated data were conducted. Current results were also examined in light of prior research with adult participants, and variations in behavioral patterns were identified. Although the sign effect appears to be more profound in adolescents compared to adu…
The Impact of CBT and ACT Models Using Psychology Trainee Therapists
2007
The present study compares the impact of individualized treatment provided by trainee therapists based on a traditional cognitive behavior therapy (CBT) and acceptance and commitment therapy (ACT) model. Fourteen therapists were given initial training in CBT and ACT. Outpatients ( N = 28) were randomized to either approach, with each therapist treating one client within each model, linked to a functional analysis. Clients treated within an ACT model showed better symptom improvement than the CBT clients, despite the fact that students felt initially less knowledgeable about ACT and were more fearful throughout when it was used. CBT improved client self-confidence more rapidly than ACT, and…
A comprehensive multicomponent school-based educational intervention did not affect fruit and vegetable intake at the 14-year follow-up
2019
Abstract The intake of fruit and vegetables is associated with beneficial health outcomes, and studies aimed at increasing fruit and vegetable intake lack long-term follow-up. The primary objective of this study was to evaluate the long-term (14-year) effects of a multicomponent school-based educational intervention targeted to increase fruit and vegetable intake in children. The secondary objective was to evaluate the potential synergistic effect between free school fruit and the educational program. A cluster randomized school-based intervention was initiated in 2001 in Norway, known as the Fruit and Vegetable Make the Marks study. In total, 38 schools were randomized; for the interventio…
Alliesthesia is greater for odors of fatty foods than of non-fat foods
2011
International audience; Alliesthesia is the modulation of the rewarding value of a stimulus according to the internal state (hungry or satiated). This study aimed to evaluate this phenomenon as a function of the nature of the stimulus (odors evoking edible and non-edible items, and the food odors evoking fatty and non-fat foods) and to compare the effectiveness of two reward evaluations (measures of pleasantness and appetence) to reveal alliesthesia. The results showed that both fatty and non-fat food odors were judged as less pleasant and less appetent when the subjects were satiated than when they were hungry, whereas no such difference was observed for non-food odors. There was a greater…
Association of Low Birth Weight With Altered Corneal Geometry and Axial Length in Adulthood in the German Gutenberg Health Study
2019
IMPORTANCE: Low birth weight is associated with altered ocular organ development in childhood, including the morphology of the eye. However, no population-based data exist about this association in adulthood. OBJECTIVE: To evaluate whether low birth weight has a long-term association with anterior segment anatomy and axial length in adulthood. DESIGN, SETTING, AND PARTICIPANTS: The Gutenberg Health Study is a population-based, observational cohort study in Germany. All participants underwent ocular biometry. Among the participants with follow-up and self-reported birth weight available, associations were assessed between low birth weight and anterior segment anatomy and axial length using m…
