We report on the multi-wavelength observations of PKS 1510-089 (a flat spectrum radio quasar (FSRQ) at z = 0.361) during its high activity period between 2008 September and 2009 June. During this 11 month period, the source was characterized by a complex variability at optical, UV, and gamma-ray bands, on timescales down to 6-12 hr. The brightest gamma-ray isotropic luminosity, recorded on 2009 Ma
The world has been afflicted heavily by the burden of coronavirus disease 2019 (COVID-19) that overwhelmed health care systems and caused severe economic and educational deficits, in addition to anxiety among the public. The main aim of this study was to evaluate the mutual effects of belief that the pandemic was the result of a conspiracy on knowledge and anxiety levels among students at the Univ
Additions B and E to LXX Esther have been variously dated from the second century BCE to the first century CE. This study links the two Greek Additions, on the one hand, with Philo’s writings through the concept of the “evil-hating justice” and, on the other hand, with the historical persons and events related to the Jewish-Alexandrian conflict of 38-41 CE, and dates their composition or final red
Spatiotemporal variation in natural selection is expected, but difficult to estimate. Pollinator-mediated selection on floral traits provides a good system for understanding and linking variation in selection to differences in ecological context. We studied pollinator-mediated selection in five populations of Dalechampia scandens (Euphorbiaceae) in Costa Rica and Mexico. Using a nonlinear path-ana
A search for heavy resonances decaying into a W or Z boson and a Higgs boson produced in proton-proton collisions at the Large Hadron Collider at s=13 TeV is presented. The analysis utilizes the dominant W→qq¯′ or Z→qq¯ and H→bb¯ decays with substructure techniques applied to large-radius jets. A sample corresponding to an integrated luminosity of 139 fb-1 collected with the ATLAS detector is anal
Amazonian ecosystems range from rainforest to open dryland vegetation, with a following decrease in biomass along the moisture gradient. Biomass can vary greatly at the ecological transition zone between grass dominated savannahs and the forest. It is not well understood if the transition zone could expand under climate change, and thereby reduce ecosystem stability and carbon storage in biomass.
PURPOSE: To study practice patterns in European cataract surgery over a 10-year period. SETTING: European clinics affiliated to the European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO). DESIGN: Registry cohort study. METHODS: The EUREQUO contains preoperative, intraoperative, and postoperative parameters reported by surgeons in many European clinics. All data reporte
Modern film cooling is an essential method to protect the turbine blade from the hot gas, and the issue about how to improve the film cooling performance has attracted much attention. In this study, a tree-shaped film cooling structure is carried out to improve the overall effectiveness and better decrease the metal temperature of the blade at the same time. To validate the superiority of the prop
The coherent generation of synchrotron radiation by an electron storage ring is predicted for wavelengths equal to or longer than the electron bunch length. With typical bunch lengths of approximately 1 cm, diffraction and chamber- screening effects have so-far blocked observation of coherent radiation from a conventional radiation beam line. In the low-energy, second-generation light source MAX-I
Recently, metal-halide perovskites have emerged as a candidate for optoelectronic applications such as photodetectors. However, the poor device performance and instability have limited their future commercialization. Herein, we report the spontaneous growth of perovskite/N-rGO hybrid structures using a facile solution method and their applications for photodetectors. In the hybrid structures, pero
This study presents a state-of-the-art overview on the application of ultrasound technology in the drying of food products, including the ultrasound pre-treatment and ultrasound assisted drying. The effect of main parameters and ultrasound technology on the drying kinetics and food quality were discussed. Inconsistencies were pointed out and analyzed in detail. Results showed that for ultrasound p
Realistic depictions of past land cover are needed to investigate prehistoric environmental changes, effects of anthropogenic deforestation, and long-term land cover-climate feedbacks. Observation-based reconstructions of past land cover are rare, and commonly used model-based reconstructions exhibit considerable differences. Recently, Pirzamanbein et al. (2018, 10.1016/j.spasta.2018.03.005, Spati
The aim of this study is to explore the IPS implementation process in a first-episode psychosis (FEP) mental health service team in Sweden. More specifically, the study explores how integration processes and critical situations are perceived over time by team members who originated from two diverse welfare organizations. A serial interview design was used (initially, at 6 and 12 months) to describ

Short description of the infrastructure. This first MultiPark-purchased confocal was awarded to GK Gouras in 2012. Bengt Mattsson from the Regenerative Neurobiology group has been the
On the nature and expression of ethnic prejudice: On the nature and expression of ethnic prejudice as seen in judgments of pictorial stimuli Bert Westerlundh, Sven Birger Hansson, Fredrik Björklund, and Martin Bäckström Department of Psychology, Lund University1 In Study 1 (N = 120), pictures of violent behavior taking place within or between ethnic groups were rated under different instructions.

In this study, the thermal behavior in a Type IV hydrogen storage tank during fast charging was investigated by establishing a 2-dimensional axisymmetric model. The thermal properties of the real high-pressure hydrogen were considered and obtained from REFPROP software. The computing mesh with 15312 girds, the time step of 0.001 s, and the Realizable k-ε turbulence model were chosen to simulate hi
Background There is a lack of contemporary data describing patients with left ventricular (LV) systolic dysfunction post myocardial infarction (MI) in terms of symptom burden and secondary prevention measures. The aim of this study was to describe patients with various degrees of LV systolic dysfunction after a first MI, their symptom burden, quality of life and adherence to recommended secondary
