What do counsellors need to know about male depression?

© 2017 Informa UK Limited, trading as Taylor & Francis Group The lower reported prevalence of depression in men has been related to depression not being as well-recognised in men as it is in women. We sought to understand the clinical under-recognition of depression in men by reviewing some of the key evidence on male depression, concentrating on practices in the UK. Additionally, we aimed to draw conclusions that would contribute to the improvement of health promotion and of the diagnosis for male depression. Our perusal of the available evidence has revealed that some depressed men experience significant difficulties not only in disclosing but also in identifying their depression and that men often exhibit atypical symptoms such as anger. Furthermore, depressed men are often involved in attempts to self-manage their depressive symptoms. This stoic approach compromises the well-being of depressed men and it discourages them from accessing appropriate support resources. We conclude with suggestions for practice and research

Using Data Lake Stack in Animal Sciences

Big Data is a theme that receives a lot of attention, and is often characterised as managing and analysing large datasets to reveal new valuable patterns. In the livestock domain, big data is also becoming more common and is being anchored into the mind-set of researchers, due to, for example, sensors generating ..

On a transmission problem for the time-harmonic Maxwell equations

The transmission for the time-harmonic Maxwell equations is studied for the case of an infinitely stratified, nested, bonded scatterer, whose homogeneous layers consist of different materials. The existence and uniqueness of solutions is proved. Moreover, an integral representation of the total exterior field is constructed, and the asymptotic behaviour of the scattered wave in the radiation region is studied

Low-frequency acoustic scattering by an infinitely stratified scatterer

In this work we consider the problem of scattering of a plane acoustic wave by an infinitely stratified scatterer with a soft, a rigid or a resistive core. Firstly, we prove the existence and uniqueness of solutions of this problem. Then using the low-frequency approximation, we reduce it to an iterative sequence of potential problems. Bounds for the low-frequency coefficients and for the normalized scattering amplitude are derived

Pacific circulation response to eastern Arctic sea ice reduction in seasonal forecast simulations

Recent studies point to the sensitivity of mid-latitude winter climate to Arctic sea ice variability. However, there remain contradictory results in terms of character and timing of Northern Hemisphere large-scale circulation features to Arctic sea ice changes. This study assesses the impact of realistic late autumn eastern Arctic sea ice anomalies on atmospheric wintertime circulation at mid-latitudes, pointing to a hidden potential for seasonal predictability. ​Using a dynamical seasonal prediction system, an ensemble of seasonal forecast simulations of 23 historical winter seasons is run with reduced November sea ice cover in the Barents-Kara Seas, and is compared to the respective control seasonal hindcast simulations set. ​A non energy-conserving approach is adopted for achieving the desired sea ice loss, with artificial heat being added conditionally to the ocean surface heat fluxes so as to inhibit the formation of sea ice during November. Our results point to a robust atmospheric circulation response in the North Pacific sector, similar to previous findings on the multidecadal timescale. Specifically, an anticyclonic anomaly at upper and lower levels is identified over the eastern midlatitude North Pacific, leading to dry conditions over the North American southwest coast. The responses are related to a re-organization (weakening) of west-Pacific tropical convection and interactions with the tropical Hadley circulation. ​A possible interaction of the poleward-shifted Pacific eddy-driven jet stream and the Hadley cell is discussed​. ​The winter circulation response in the Euro-Atlantic sector is ephemeral in character and statistically significant in January only, corroborating previous findings of an intermittent and non-stationary Arctic sea ice-NAO link during boreal winter. These results ​aid our understanding of the seasonal impacts of reduced eastern Arctic sea ice on the midlatitude atmospheric circulation with implications for seasonal predictability in wintertime

Affine and toric hyperplane arrangements

We extend the Billera-Ehrenborg-Readdy map between the intersection lattice and face lattice of a central hyperplane arrangement to affine and toric hyperplane arrangements. For arrangements on the torus, we also generalize Zaslavsky's fundamental results on the number of regions.Comment: 32 pages, 4 figure

Printed elastic membranes for multimodal pacing and recording of human stem-cell-derived cardiomyocytes

Bioelectronic interfaces employing arrays of sensors and bioactuators are promising tools for the study, repair and engineering of cardiac tissues. They are typically constructed from rigid and brittle materials processed in a cleanroom environment. An outstanding technological challenge is the integration of soft materials enabling a closer match to the mechanical properties of biological cells and tissues. Here we present an algorithm for direct writing of elastic membranes with embedded electrodes, optical waveguides and microfluidics using a commercial 3D printing system and a palette of silicone elastomers. As proof of principle, we demonstrate interfacing of cardiomyocytes derived from human induced pluripotent stem cells (hiPSCs), which are engineered to express Channelrhodopsin-2. We demonstrate electrical recording of cardiomyocyte field potentials and their concomitant modulation by optical and pharmacological stimulation delivered via the membrane. Our work contributes a simple prototyping strategy with potential applications in organ-on-chip or implantable systems that are multi-modal and mechanically soft
