Single electron yields from semileptonic charm and bottom hadron decays in Au+Au collisions at sNN =200 GeV

The PHENIX Collaboration at the Relativistic Heavy Ion Collider has measured open heavy flavor production in minimum bias Au+Au collisions at sNN=200 GeV via the yields of electrons from semileptonic decays of charm and bottom hadrons. Previous heavy flavor electron measurements indicated substantial modification in the momentum distribution of the parent heavy quarks owing to the quark-gluon plas

Accuracy of MRI in early rectal cancer: national cohort study

Radiological staging of rectal cancer dictates subsequent patienttreatment. In early-stage disease, local excision is associatedwith reduced morbidity, mortality, and costs, and maintainsbowel continuity compared with surgery, where the whole orpart of the rectum is resected1–3. Nearly 90 per cent of patientswith T1 rectal cancer have N0 disease and are therefore potentially curable with local res

Forward J/ψ production in U + U collisions at sNN =193 GeV

The invariant yields, dN/dy, for J/ψ production at forward rapidity (1.2<|y|<2.2) in U+U collisions at sNN=193GeV have been measured as a function of collision centrality. The invariant yields and nuclear-modification factor RAA are presented and compared with those from Au+Au collisions in the same rapidity range. Additionally, the direct ratio of the invariant yields from U+U and Au+Au collision

“You leave the chat with a different feeling than when you came in.”: A Content Analysis about Negative Experiences Following Instant Messaging Among Adolescents with and without a History of Non-Suicidal Self-Injury

Background: Instant messaging platforms seem to positively contribute to adolescent emotional well-being. However, some scholars show a link between the use of these platforms and negative emotional experiences.These emotions could be perceived as even more overwhelming for certain subgroups of adolescents, such as those who engage in non-suicidal self-injury (NSSI), and lead to self-injury to dea

Production of light nuclei and anti-nuclei in pp and Pb-Pb collisions at energies available at the CERN Large Hadron Collider

The production of (anti-)deuteron and (anti-)He3 nuclei in Pb-Pb collisions at sNN=2.76 TeV has been studied using the ALICE detector at the LHC. The spectra exhibit a significant hardening with increasing centrality. Combined blast-wave fits of several particles support the interpretation that this behavior is caused by an increase of radial flow. The integrated particle yields are discussed in t

Scaling properties of fractional momentum loss of high- pT hadrons in nucleus-nucleus collisions at sNN from 62.4 GeV to 2.76 TeV

Measurements of the fractional momentum loss (Sloss≡δpT/pT) of high-transverse-momentum-identified hadrons in heavy-ion collisions are presented. Using π0 in Au+Au and Cu+Cu collisions at sNN=62.4 and 200 GeV measured by the PHENIX experiment at the Relativistic Heavy Ion Collider and and charged hadrons in Pb+Pb collisions measured by the ALICE experiment at the Large Hadron Collider, we studied

The formation and fate of planetesimals at planetary gap edges

High resolution observations with ALMA have revealed that concentric rings and gaps are common features in protoplanetary disks. The favored mechanism for creating these substructures are planet-disk interactions, in which growing planets open gaps in the disk, and particles become trapped at the pressure maxima that form at the corresponding gap edges. Since the particle density in these pressure

Policy Choices in African Structural Adjustment : An Exploration of Sectoral Continuity

Between 1980 and 2000, a number of Sub-Saharan African countries entered into conditional structural adjustment lending arrangements with the International Monetary Fund (IMF) in response to economic crisis and decline. Despite the fact that the crises had been due in part to long-term overdependence on primary sector activities, such as cash crop agriculture and natural resource extraction, many

Will the EU Medical Device Regulation help to improve the safety and performance of medical AI devices?

Concerns have been raised over the quality of evidence on the performance of medical artificial intelligence devices, including devices that are already on the market in the USA and Europe. Recently, the Medical Device Regulation, which aims to set high standards of safety and quality, has become applicable in the European Union. The aim of this article is to discuss whether, and how, the Medical

Return of genomic results does not motivate intent to participate in research for all : Perspectives across 22 countries

Purpose: The aim of this study was to determine how attitudes toward the return of genomic research results vary internationally. Methods: We analyzed the “Your DNA, Your Say” online survey of public perspectives on genomic data sharing including responses from 36,268 individuals across 22 low-, middle-, and high-income countries, and these were gathered in 15 languages. We analyzed how participan

An Intelligent Surveillance System

This paper presents the outline, goal, achievements,and work in progress of the hardware image processing projectat the Digital-ASIC group at Lund institute of technology (LTH).The project attempts to automate a surveillance system for indoormonitoring. This includes motion segmentation, image filtering,feature extraction, tracking, and classification. Hardware accel-erators for segmentation and f

Lipase-Mediated Syntheses of Trimethylolpropane-Based Biolubricant and Cyclic Carbonate

Popular Abstract in English Popular Summary Since the beginning of mankind, humans have managed to find ways to make use of the resources available at hand in order to survive and even to improve their livelihoods. The basic needs for food as well as other amenities were met from plant- and animal resources until the 19th century when industrial revolution changed the base of production to fossilAbstract Biocatalysis is considered as benign and efficient alternative to chemical catalysis for organic syntheses. Lipases are the most versatile biological catalysts implemented so far with great potential for production of different chemicals and materials in non-conventional reaction media. This thesis presents investigations on lipase catalyzed esterification and transesterification reaction
