The momentum distribution of electrons from semileptonic decays of charm and bottom quarks for midrapidity |y|< 0.35 in p+p collisions at s=200 GeV is measured by the PHENIX experiment at the Relativistic Heavy Ion Collider over the transverse momentum range 2 < p(T)< 7 GeV/c. The ratio of the yield of electrons from bottom to that from charm is presented. The ratio is determined using partial D/D
Transverse single-spin asymmetries to probe the transverse-spin structure of the proton have been measured for neutral pions and nonidentified charged hadrons from polarized proton-proton collisions at midrapidity and root s = 200 GeV. The data cover a transverse momentum (pT) range 1.0-5.0 GeV/c for neutral pions and 0.5-5.0 GeV/c for charged hadrons, at a Feynman-x value of approximately zero. T
Agrarian history and local cultural landscape dynamics have been documented through pollen analysis of a peat core within the hamlet of Yttra Berg, which is situated in an upland area of southwest Sweden. The sequence covers the last 5,000 years, from Neolithic to modern time. Wood pasturing started at 2000 b.c., followed by grazing and small-scale cultivation with 500 year cycles from 650 b.c., a
Studies of climatic change and adaptation to climate change can include a wide range of methodologies and approaches. As one of such approaches, we here present meteorological measurement data from a site in the Demokeya experimental forest outside El Obeid in North Kordofan State of Sudan. We hope this descriptive note can inform about the available meteorological data, as well as to promote and
Abstract The nutrient and carbon (C) allocation dynamics in mycorrhizal hyphal networks cause variation in costs and benefits for individual plants and fungi and influence the productivity, diversity and C cycling in ecosystems. We manipulated light and phosphorus (P) availability in a pot experiment with Trifolium subterraneum colonised by the arbuscular mycorrhizal (AM) fungus Glomus intraradice
Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary-scaled p+p collisions. These measurements indicate that charm and bottom quarks interact with the hot dense matter produced in heavy-ion collisions much more than expected. Here we extend these studies to two-particle correlations w
Ciliate assemblages play a significant role in the microbial food web. The effects of environmental temperature on assemblage composition may be influenced by abiotic factors such as seasonality and disturbance, but the effects of temperature on ciliate assemblages found on different substrata have not been explored. Sandy bottoms and submerged rocks harbour dissimilar ciliate assemblages, and it
Background: Continuous abstinence and retention in treatment for alcohol and drug use disorders are central challenges for the treatment providers. The literature has failed to show consistent, strong predictors of retention. Predictors and treatment structure may differ across treatment modalities. In this study the structure was reinforced by the addition of supervised urine samples three times
PHENIX has measured the centrality dependence of midrapidity pion, kaon, and proton transverse momentum distributions in d+Au and p+p collisions at root s(NN) = 200 GeV. The p+p data provide a reference for nuclear effects in d+Au and previously measured Au+Au collisions. Hadron production is enhanced in d+Au, relative to independent nucleon-nucleon scattering, as was observed in lower energy coll
Introduction: Several common alleles have been shown to be associated with breast and/or ovarian cancer risk for BRCA1 and BRCA2 mutation carriers. Recent genome-wide association studies of breast cancer have identified eight additional breast cancer susceptibility loci: rs1011970 (9p21, CDKN2A/B), rs10995190 (ZNF365), rs704010 (ZMIZ1), rs2380205 (10p15), rs614367 (11q13), rs1292011 (12q24), rs107
Individuals with autism spectrum disorder (ASD) experience high levels of anxiety symptomatology with an estimated prevalence rate of anxiety disorders as high as 40 %. It is likely that anxiety is prominent in individuals with ASD throughout the life-span and that factors such as age, IQ, and ASD symptoms may influence the rates, symptoms, or anxiety subtypes. The high comorbidity rate of anxiety
The functional role of herbivores in tropical rainforests remains poorly understood. We quantified the magnitude of, and underlying controls on, carbon, nitrogen and phosphorus cycled by invertebrate herbivory along a 2800m elevational gradient in the tropical Andes spanning 12 degrees C mean annual temperature. We find, firstly, that leaf area loss is greater at warmer sites with lower foliar pho
The aim of this article is to give a tentative illustration of how a creative, postpolitical citizen is imagined and encouraged to unfold within the frame of a city renewal project. As a starting point, the article outlines an exploratory framework structured through the analytical concept of postpolis. Postpolis is a term that offers an illustration of the distinguishing qualities of contemporary
General hospital care and treatment of mentally ill patients in a Swedish town was studied in records for 503 patients, 1896–1905. Restraint was extremely rare; 65% left the hospital as healthy or improved. Non-psychotic and alcoholic patients spent fewer days in hospital than patients with psychosis or dementia. There was no evidence of a social status bias. For 36% of the patients a certificate
A three stacked power amplifier implemented in 28nm fully depleted silicon-on-insulator complementary metal oxide semi-conductor technology (FDSOI CMOS) is presented. It has a differential architecture with on-chip input and output transformer baluns. The PA achieves a saturated output power level of 17.9dBm with a peak power added efficiency of 7% and an output referred gain compression point of
IMPORTANCE Delayed umbilical cord clamping has been shown to improve iron stores in infants to 6 months of age. However, delayed cord clamping has not been shown to prevent iron deficiency or anemia after 6 months of age. OBJECTIVE To investigate the effects of delayed umbilical cord clamping, compared with early clamping, on hemoglobin and ferritin levels at 8 and 12 months of age in infants at h
