We present a sample of 705 local giant stars observed using the New Mexico State University 1 m telescope with the Sloan Digital Sky Survey-III/Apache Point Observatory Galactic Evolution Experiment (APOGEE) spectrograph, for which we estimate stellar ages and the local star formation history (SFH). The high-resolution (R ̃ 22,500), near infrared (1.51-1.7 μm) APOGEE spectra provide measurements o
We present new BVI photometry containing 40,000 stars of the Galactic globular cluster M15 (NGC 7078) covering a 25×25 arcminute area centered on the cluster with a magnitude range from the tip of the Red Giant Branch to three magnitudes below the main sequence turn-off. Using α -enhanced Dartmouth Stellar Evolution Program models, we find an age of 13.0 ± 1.0 Gyr and distance modulus of (m−M)V=15
As a follow-up of a previous investigation in which semisynthetic damsin derivatives were shown to possess up to 10 times higher cytoxicity in JIMT-1 breast cancer cells compared to normal breast epithelial MCF-10A cells, a range of new derivatives were prepared and assayed toward the same cells. Damsin, a natural plant metabolite containing a α-methylene-γ-lactone (or 3-methylenedihydro- furan-2(
Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we h
This paper developed a multi-space prediction model for seasonal precipitation using a high-resolution grid dataset (0.5° × 0.5°) together with climate indices. The model is based on principal component analyses (PCA) and artificial neural networks (ANN). Trend analyses show that mean annual and seasonal precipitation in the area is increasing depending on spatial location. For this reason, a mult
Cancer is the leading cause of death worldwide, and there is a constant need for new treatmentstrategies. Sesquiterpene lactones containing a 3-methylenedihydrofuran-2(3H)-one (or α-methylene-γ-lactone) moiety, for example damsin (1), are Michael acceptors that affect biological processes such as cell proliferation, death/apoptosis, and cell migration, by interfering with cell signalling pathways.
The right to leave a country is enshrined in both international human rights law and its European counterpart. It is a right which is independent and does not require the individual exercising it to show that he or she is admissible in some other country. It is exercisable even in the absence of evidence of possible admission to a destination country. However, in Europe (and some other parts of th
Temperature and precipitation extremes are the dominant causes of natural disasters. In this study, seven indices of extreme temperature and precipitation events in Gansu Province, China, were analysed for the period 1961–2017. An abrupt climate shift was recorded during 1980–1981. Thus, the study period was divided into a preshift (before the climate shift) period 1961–1980 and an aftshift (after
The 2019 Nîmes International Symposium in Antibiotic Therapy Optimisation aimed at determining the best approaches of a number of the antibiotic management strategies for critically ill patients. Experts reviewed the latest literature relating to requirements for an optimal antibiotic stewardship program, risks of sub-therapeutic dosing of antibiotics in critically ill patients, persisting issues
Evidence suggests an influence of sex hormones on cutaneous melanoma risk, but epidemiologic findings are conflicting. We examined the associations between use of oral contraceptives (OCs) and menopausal hormone therapy (MHT) and melanoma risk in women participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). EPIC is a prospective cohort study initiated in 1992 in 1
Regional and global assessments periodically update what we know, and highlight what remains to be known, about the linkages between people and nature that both define and depend upon the state of the environment. To guide research that better informs policy and practice, we systematically synthesize knowledge gaps from recent assessments of four regions of the globe and three key themes by the In
Over the past several years an increasing number of terrorist attacks committed in the name of Islam and targeting civilians have taken place in many Western democracies, calling for more research on the impact of these exogenous events on citizens’ attitudes towards immigrants. Using a quasi‐experimental design, this study examines the short‐term effect of the Paris attacks of the night of 13 Nov
As interest in the processes of integration of immigrants and ethnic minorities grows among European scholars, the role of multiple actors in shaping civic and political participation by people of migrant background needs to be further examined. Building on the literature on migration, this study addresses the following research question: What accounts for differences in forms of civic and politic
