Subsurface microstructural alterations and residual stresses caused by machining significantly affect component lifetime and performance by influencing fatigue, creep, and stress corrosion cracking resistance. Assessing the surface quality of a machined part by characterizing subsurface microstructural alterations and residual stresses is essential for ensuring part performance and lifetime in aer
Two-dimensional spectroscopy has recently revealed the oscillatory behavior of the excitation dynamics of molecular systems. However, in the majority of cases there is considerable debate over what is actually being observed: excitonic or vibrational wavepacket motion or evidence of quantum transport. In this letter we present a method for distinguishing between vibrational and excitonic wavepacke
Despite improved survival for the patients with diffuse large B-cell lymphoma (DLBCL), the prognosis after relapse is poor. The aim was to identify molecular events that contribute to relapse and treatment resistance in DLBCL.
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
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.
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
Empirical research about late sexual debut and its consequences is limited, and further research is needed.
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
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
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
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
Refined mineral oil, intended for various technical applications, was enriched with carotenoids by supercritical carbon dioxide extraction using the oil itself as cosolvent. It was envisioned that the carotenoids could function as renewable oil additives, adding chemical functionality to the end product such as enhanced resistance to oxidation. In order to investigate such possible antioxidant act
