Modification of the resonance fluorescence spectrum of a two-level atom driven by a monochromatic field in the close proximity of a plasmonic nanostructure (metal sphere) is studied in detail. It is shown that one can control this spectrum by varying several key parameters: (i) the radius of the nanosphere, (ii) polarization of the incident radiation, and (iii) the atom's location around the nanos

This study reports findings from the first large-scale experiment investigating whether entrepreneurs differ 1 from other people in their willingness to expose themselves to various forms of uncertainty. A stratified random sample of 700 chief executive officers from the Yangzi delta region in China is compared to 200 control group members. Our findings suggest that in economic decisions, entrepre

Preeclampsia, a common complication of pregnancy, contributes significantly to maternal and fetal morbidity and mortality. It may lead to both quantitative and qualitative defects of maternal and neonatal platelets. In this prospective study, flow cytometry has been used to study expression of platelet-surface glycoproteins (GPs) on maternal and neonatal platelets of both healthy and preeclamptic

Migraines constitute a common neurological and headache disorder affecting around 15% of the world’s population. In addition to other mechanisms, neurogenic neuroinflammation has been proposed to play a part in migraine chronification, which includes peripheral and central sensitization. There is therefore considerable evidence suggesting that inflammation in the intracranial meninges could be a k

Atmospheric aerosols contain organic molecules that serve as cloud condensation nucleation sites and affect the climate. Several experimental and simulation studies have been dedicated to investigate their surface propensity, but the mechanisms that drive them to the water surface are still not fully understood. In this molecular dynamics (MD) simulation study, primary alcohols are considered as a

Mixed species charge and baryon balance functions are computed based on proton-proton (pp) collisions simulated with the PYTHIA8 model. Simulations are performed with selected values of the collision energy s and the Monash tune and the ropes and shoving modes of PYTHIA8 to explore whether such measurements provide useful new information and constraints on mechanisms of particle production in pp c

Syftet med uppsatsen är att finna och konkretisera möjliga faktorer som bidrar till en framgångsrik nyemission hos onoterade företag i Sverige. De faktorer kan på förhand hjälpa onoterade företag att anpassa organisationen och emissionsvillkoren till att ha så bra förutsättningar som möjligt för att genomföra en framgångsrik nyemission. Vi har utifrån en deduktiv ansats gjort en kvantitativ unders

Existing studies concerning private labels are unclear as to whether private label manufacturers carry out product development themselves. Furthermore, there is a lack of studies comparing product development processes in private label companies and national brand manufacturers. This study highlights a set of critical product development factors and assesses their prevalence in four different comp

SYFTE Syftet med uppsatsen är att analysera Svenska hedgefonders historiska avkastning beträffande riskjusterad avkastning och korrelation mot marknaden. Vidare studeras dessa faktorer ur ett investerarperspektiv för att undersöka huruvida Svenska hedgefonder fyller ett syfte som komplement i en marknadsportfölj. METOD Uppsatsen använder sig till största del av kvantitativ data som insamlas med hj

Purpose: The purpose of this study is to enhance the understanding of how different groups of consumers perceive a brand depending on whether they are exposed to influencer marketing or paid social media marketing. Methodology: A descriptive quantitative study with a between-subjects design was conducted using a digital survey. A combination of one-way ANOVA, independent samples t-test and Spear

In this work, we investigate production of Drell-Yan (DY) pairs in proton-nucleus collisions in kinematic regions where the corresponding coherence length does not exceed the nuclear radius, RA, and the quantum coherence effects should be treated with special care. The results for the nucleus-to-nucleon production ratio available in the literature so far are usually based on the assumption of a ve

We consider several simple combinatorial problems and discuss different ways to express them using polynomial equations and try to describe the Gröbner basis of the corresponding ideals. The main instruments are complete symmetric polynomials that help to express different conditions in rather compact way.

Background: The secreted enzyme EndoS, an endoglycosidase from Streptococcus pyogenes, hydrolyzes the N-linked glycan of the constant region of immunoglobulin G (IgG) heavy chain and renders the antibody unable to interact with Fc receptors and elicit effector functions. In this study we couple targeted allelic replacement mutagenesis and heterologous expression to elucidate the contribution of En

We report a case of a 5-year-old child who suffered an oral allergy syndrome and lip angiedema after eating grapes. We obtained a positive prick test with commercial grape extract and a positive prick-by-prick test with pulp and peel of fresh white grape (Moscatel variety) and pulp and peel of blue grape. Sodium dodecyl sulphate-polyacrylamide gel electrophoresis followed by immunoblotting reveale
