Higgs boson production at large transverse momentum within SMEFT: analytical results

We consider Higgs boson production through gluon fusion at large transverse momentum in hadronic collisions. We present the analytic expressions of the relevant one-loop QCD amplitudes including the effects of the complete set of dimension-six operators. The latter correspond to modifications of the top and bottom Yukawa couplings, to an effective point-like Higgs coupling to gluons and to the chromomagnetic operator of the top quark. The quantitative impact of the chromomagnetic operator is also studied. Our results confirm previous findings that the effect of the chromomagnetic operator at high $p_T$ can be large and should not be neglected.Comment: 16 pages, 5 figure

Physical Security Barrier Selection: A Decision Support Analysis

Physical security controls aim to reduce risk through their ability to systematically deter, or detect, delay and respond against deviant acts within a risk context. Holistically the aim is to increase the difficulty and risks while reducing the rewards associated with an act of deviance as captured in Clarke’s Situational Crime Prevention (SCP) framework. The efficacious implementation of such controls commensurate with the risk context requires a considered undertaking referred as informed decision‐making. Informed decision‐making is effective when a suitable choice is made accordant with base rate data that achieves its defined objectives within costs versus benefits framework. The study examined the feasibility of developing a decision support tool to enhance the selection of a suitable barrier fence system, in‐line with defence in depth to increase the efforts and risks, and reduce the rewards associated with unlawful access. The study found that a decision support tool can be developed comprising of the various contextual inputs and their relationships in achieving a contextually suitable barrier fence system, as a result enhancing the selection of situational crime prevention elements

HOX genes in high grade ovarian cancer

HOX genes are highly conserved members of the homeobox superfamily that have a crucial role in determining cellular identity. High grade ovarian cancer is the most lethal gynaecological malignancy. Our understanding of the role of HOX genes in the oncogenesis of ovarian cancer is evolving, and here we review their dysregulated expression patterns, their function in cell survival and invasion, their potential uses as biomarkers, and ways in which HOX genes are being targeted with new and existing drug

Carbon and Nitrogen Isotopic Ratio of the Water-Insoluble Fraction in Air Filter Particulate Matter

Particulate matter samples were collected during two episodes of thermal inversion (14.01-2.3.2006) and at four different air monitoring stations in Krakow (Agro: urban background site, Indu: industrial site at Nowa Huta, Poly: domestic coal heating district, Traffic: traffic site) and from the Zakopane sub-urban mountain site (Zakopane), dominated by domestic coal heating. The carbon and nitrogen isotopic compositions of aerosol particles collected in the city of Krakow were measured in 2006 as part of the JRC-IES Krakow project, for which the samples were taken. A total of 42 samples (including 24 source samples) was analysed by Isotope Ratio Mass Spectrometry (IRMS) for isotopic ratios of N and C. The results for samples from different locations show clear grouping of related samples. The leftover of samples provided within the Krakow project were stored in the refrigerator. After one year of cool storage the EA-IRMS measurement was repeated and water extraction was applied. The aim of this experiment was to get more isotopic data for source apportionment. The results showed that the isotopic values of some source samples obtained in 2007 are different from these measured in 2006. However, these differences were not observed for ambient air samples. The possible explanation could be improper storage condtions causing continued reactions between products adsorbed on the filter during storage in the refrigerator. The water extraction removed water soluble inorganic and organic nitrogen-containing compounds and caused the changes in delta15N vs. Air. In this study it is difficult to make a link between sources and ambient air samples after application of water extraction because of the problem with instability of isotopic compositions of the original sources samples.JRC.D.4-Isotope measurement

Multidecadal (1960–2011) shoreline changes in Isbjørnhamna (Hornsund, Svalbard)

A section of a gravel-dominated coast in Isbjørnhamna (Hornsund, Svalbard) was analysed to calculate the rate of shoreline changes and explain processes controlling coastal zone development over last 50 years. Between 1960 and 2011, coastal landscape of Isbjørnhamna experienced a significant shift from dominated by influence of tide-water glacier and protected by prolonged sea-ice conditions towards storm-affected and rapidly changing coast. Information derived from analyses of aerial images and geomorphological mapping shows that the Isbjørnhamna coastal zone is dominated by coastal erosion resulting in a shore area reduction of more than 31,600 m2. With ~3,500 m2 of local aggradation, the general balance of changes in the study area of the shore is negative, and amounts to a loss of more than 28,000 m2. Mean shoreline change is −13.1 m (−0.26 m a−1). Erosional processes threaten the Polish Polar Station infrastructure and may damage of one of the storage buildings in nearby future
