Genetic and epigenetic catalysts in early-life programming of adult cardiometabolic disorders.
Evidence has emerged across the past few decades that the lifetime risk of developing morbidities like type 2 diabetes, obesity, and cardiovascular disease may be influenced by exposures that occur in utero and in childhood. Developmental abnormalities are known to occur at various stages in fetal growth. Epidemiological and mechanistic studies have sought to delineate developmental processes and
The Parity of Directed Hamiltonian Cycles
We present a deterministic algorithm that given any directed graph on n vertices computes the parity of its number of Hamiltonian cycles in O(1.619n) time and polynomial space. For bipartite graphs, we give a 1.5npoly(n) expected time algorithm. Our algorithms are based on a new combinatorial formula for the number of Hamiltonian cycles modulo a positive integer.

Lymphoid organisation in labial salivary gland biopsies is a possible predictor for the development of malignant lymphoma in primary Sjogren's syndrome
Objective The development of non-Hodgkin's lymphoma (NHL) confers a high risk of mortality in primary Sjogren's syndrome (pSS) patients, but the sensitivity and specificity of proposed lymphoma predictors are insufficient for practical use. The performance of lymphoid organisation in the form of germinal centre (GC)-like lesions was evaluated in labial salivary gland biopsies taken at pSS diagnosi
Differences in sexual behavior, health, and history of child abuse among school students who had and had not engaged in sexual activity by the age of 18 years: a cross-sectional study.
Empirical research about late sexual debut and its consequences is limited, and further research is needed.

Strategies and Policies for the Bioeconomy and Bio-based Economy: An Analysis of Official National Approaches
The onset of formulating strategies and policies regarding the bioeconomy can be, at least partly, attributed to the publication of the bioeconomy policy agenda by the OECD in 2009. The aim of this study is to analyse selected national strategies and policies regarding the development of a bioeconomy and to clarify similarities and differences between them. The article presents a comparative overv

HTLV-1 in rural Guinea-Bissau: prevalence, incidence and a continued association with HIV between 1990 and 2007
Background: HTLV-1 is endemic in Guinea-Bissau, and the highest prevalence in the adult population (5.2%) was observed in a rural area, Caio, in 1990. HIV-1 and HIV-2 are both prevalent in this area as well. Cross-sectional associations have been reported for HTLV-1 with HIV infection, but the trends in prevalence of HTLV-1 and HIV associations are largely unknown, especially in Sub Saharan Africa
Immigrants’ Returns to Schooling in Sweden
The aim of this paper is to find out if the returns to immigrants’ schooling are lower than the returns to natives’ schooling. In addition the paper tries to establish whether immigrants who invest in different amounts of Swedish education also differ in their returns to schooling. For immigrants arriving in Sweden as adults, the returns to schooling are on average one log point lower than for nat
Meat consumption and prospective weight change in participants of the EPIC-PANACEA study
Background: Meat intake may be related to weight gain because of its high energy and fat content. Some observational studies have shown that meat consumption is positively associated with weight gain, but intervention studies have shown mixed results. Objective: Our objective was to assess the association between consumption of total meat, red meat, poultry, and processed meat and weight gain afte

Measurement of three-jet production cross-sections in [Formula: see text] collisions at 7 [Formula: see text] centre-of-mass energy using the ATLAS detector.
Double-differential three-jet production cross-sections are measured in proton-proton collisions at a centre-of-mass energy of [Formula: see text] using the ATLAS detector at the large hadron collider. The measurements are presented as a function of the three-jet mass [Formula: see text], in bins of the sum of the absolute rapidity separations between the three leading jets [Formula: see text]. In

Comparison of Hybrid Control Techniques for Buck and Boost DC-DC Converters
Five recent techniques from hybrid and optimal control are evaluated on two power electronics benchmark problems. The benchmarks involve a number of practically interesting operating scenarios for fixed-frequency synchronous dc-dc converters. The specifications are defined such that good performance can only be obtained if the switched and nonlinear nature of the problem is accounted for during th
