Viviparous mothers impose stronger glucocorticoid-mediated maternal stress effects on their offspring than oviparous mothers

Maternal stress during gestation has the potential to affect offspring development via changes in maternal physiology, such as increases in circulating levels of glucocorticoid hormones that are typical after exposure to a stressor. While the effects of elevated maternal glucocorticoids on offspring phenotype (i.e., “glucocorticoid-mediated maternal effects”) have been relatively well established

D-xylose sensing in saccharomyces cerevisiae : Insights from D-glucose signaling and native D-xylose utilizers

Extension of the substrate range is among one of the metabolic engineering goals for microorganisms used in biotechnological processes because it enables the use of a wide range of raw materials as substrates. One of the most prominent examples is the engineering of baker’s yeast Saccharomyces cerevisiae for the utilization of D-xylose, a five-carbon sugar found in high abundance in lignocellulosi

Probing the gluon plasma with charm balance functions

Recent theoretical explanations for how hydrodynamic-like flow can build up quickly in small collision systems (hydrodynamization) has led to a microscopic picture of flow building up in a gluon-dominated phase before chemical equilibrium between quarks and gluons has been attained. The goal of this contribution to Offshell-2021 is to explore consequence of assuming a long-lived gluon-dominated ph

The increasing influence of siblings in social mobility. A long-term historical view (Barcelona area, 16th-19th centuries)

Parental influence over children’s status attainment has historically been argued to be key. However, the cross-sibling influence has been scarcely studied for historical periods and for steam family societies, being the most long-lasting relationship across individuals’ lives once childhood was surpassed. We investigate how intra-generational family relationships determine the social destiny of s

Community Energy in the Eastern Baltic Sea Region: From Standstill to First Steps

This chapter aims to explore community energy (CE)—energy communities that are established and run by private citizens—in four Eastern European countries. The chapter first analyses general contextual conditions supporting the diffusion of CE initiatives in the Baltic Sea Region. Subsequently, it reports the findings of four case studies from Estonia, Latvia, Lithuania, and Poland illustrating som

PR interval prolongation and 1-year mortality among emergency department patients : A multicentre transnational cohort study

Objectives Emerging evidence supports that PR interval prolongation is associated with increased mortality. However, most previous studies have limited confounder control, and clinical impact in a population of acute ill patients is unknown. The aim of this study was to investigate whether 1-year all-cause mortality was increased in patients presenting with PR interval prolongation in the emergenc

Rate and characteristics of infection after transrectal prostate biopsy : a retrospective observational study

Objectives: The aim of this study was to assess the incidence of infection after transrectal prostate biopsy (TRbx). Secondary objectives were to describe infection characteristics, antibiotic resistance patterns, ICD-10 coding, and costs. Methods: TRbx carried out at the hospitals of Ängelholm and Helsingborg, Scania, Sweden, between October 2017 and March 2019, were identified based on the NOMES

Using the modis sensor for snow cover modeling and the assessment of drought effects on snow cover in a mountainous area

Snow is one of the essential factors in hydrology, freshwater resources, irrigation, travel, pastimes, floods, avalanches, and vegetation. In this study, the snow cover of the northern and southern slopes of Alborz Mountains in Iran was investigated by considering two issues: (1) Estimating the snow cover area and the (2) effects of droughts on snow cover. The snow cover data were monitored by ima

Developing hybrid time series and artificial intelligence models for estimating air temperatures

Air temperature is a vital meteorological variable required in many applications, such as agricultural and soil sciences, meteorological and climatological studies, etc. Given the importance of this variable, this study seeks to estimate minimum (Tmin), maximum (Tmax), and mean (T) air temperatures by applying a linear autoregressive (AR) time series model and then developing a hybrid model by mea

Diagnostik och behandling av fimos hos pojkar kan delegeras

Phimosis in boys is a common condition. In the majority of cases it is physiological without symptoms. Symptomatic phimosis can often be treated successfully with local steroid cream - only a minority of patients need surgery. This study concludes that diagnosis, information to patients and guardians, initiation and follow-up of local steroid treatment can successfully, and safely, be delegated to

Modeling of electric power system in electric vehicles

The market for partly or fully electrified vehicles is expanding fast. The number of sources and loads that are connected to the vehicles traction voltage systems (TVS) increase and thus also the EMC requirements on these sources and loads. These requirements should make sure that neither function nor lifetime of any source or load is severely affected by another. The EMC requirements include both

Vocabulary learning from watching YouTubevideos and reading blog posts

This study compared second languagevocabulary acquisition from engagement with two different online media: written blog posts and video blogs. It also explored whether there were differences betweenwhich aspects of vocabulary knowledge(i.e., orthography, semantics, and grammatical function) were best learned from these media. The results showed that incidental vocabulary learning occurred in appro

Observation of a K̄ NN bound state in the He 3 (K-, Λp)n reaction OBSERVATION of A K̄ NN BOUND STATE ... T. YAMAGA et al.

We have performed an exclusive measurement of the K-+He3→Λpn reaction at an incident kaon momentum of 1GeV/c. In the Λp invariant mass spectrum, a clear peak was observed below the mass threshold of K̄+N+N, as a signal of the kaonic nuclear bound state, K̄NN. The binding energy, decay width, and S-wave Gaussian reaction form factor of this state were observed to be BK=42±3(stat.)-4+3(syst.)MeV, ΓK

The biophysical climate mitigation potential of boreal peatlands during the growing season

Peatlands and forests cover large areas of the boreal biome and are critical for global climate regulation. They also regulate regional climate through heat and water vapour exchange with the atmosphere. Understanding how land-atmosphere interactions in peatlands differ from forests may therefore be crucial for modelling boreal climate system dynamics and for assessing climate benefits of peatland

Structural biology of calcium phosphate nanoclusters sequestered by phosphoproteins

Biofluids that contain stable calcium phosphate nanoclusters sequestered by phosphopeptides make it possible for soft and hard tissues to co-exist in the same organism with relative ease. The stability diagram of a solution of nanocluster complexes shows how the minimum concentration of phosphopeptide needed for stability increases with pH. In the stable region, amorphous calcium phosphate cannot

Proteins in deep eutectic solvents : Structure, dynamics and interactions with the solvent

The structure and dynamics of proteins in solution are closely related to their activity and, ultimately, to their performance in products and technologies, for example, drug formulations and enzymatic catalysis. With this in mind, the study of the fundamental behavior of proteins in deep eutectic solvents not only provides insight into a novel alternative to aqueous and molecular organic solvents
