Relationships between housing and healthy aging in very old age

Abstract: Purpose: The aim of this work is to examine the relationship between aspects of objective and perceived housing and aspects of healthy aging, defined as independence in daily activities and subjective wellbeing. Furthermore, this research examined the comparability of relationships between housing and healthy aging in the five European countries. Design and Methods: Data were drawn from the ENABLE-AGE Project, from home interviews with a sample of 1,918 very old people aged 75. to 89 years living alone in their own homes in Swedish, German, British, Hungarian and Latvian urban areas. Results: Participants living in better accessible homes, who perceive their home as meaningful and useful, and who think that external influences are not responsible for their housing situation are more independent in daily activities and have a better sense of well-being. Moreover, these results apply to all five national samples. Implications: The findings can widen the perspective when striving for barrier-free building standards, to encompass a holistic approach that takes both objective and perceived aspects of housing into account. Home modification and relocation should not be prescribed, but need to be negotiated with older adults to take into account their personal preferences.

An atomic-level model for studying the dynamics of edge dislocations in metals

Abstract: A model for simulating the dynamic behaviour of edge dislocations in metals at the atomic level is presented. The model extends an earlier approach based on an array of edge dislocations periodic in the Burgers vector direction and allows the external action (either shear strain or resolved shear stress), crystal energy, plastic displacement and dislocation position and velocity to be determined unambiguously. Two versions of the model for either static or dynamic conditions, i.e. zero or non-zero temperature, are described. The model is tested for elastic response of a perfect crystal and the atomic properties of a ½111 edge dislocation in a model of bcc Fe. Several examples of dislocation glide behaviour and dislocation–obstacle interactions at zero and non-zero temperature are presented and discussed.

Search for dark matter and other new phenomena in events with an energetic jet and large missing transverse momentum using the ATLAS detector

Abstract: Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses proton-proton collision data corresponding to an integrated luminosity of 36.1 fb−1 at a centre-of-mass energy of 13 TeV collected in 2015 and 2016 with the ATLAS detector at the Large Hadron Collider. Events are required to have at least one jet with a transverse momentum above 250 GeV and no leptons (e or μ). Several signal regions are considered with increasing requirements on the missing transverse momentum above 250 GeV. Good agreement is observed between the number of events in data and Standard Model predictions. The results are translated into exclusion limits in models with pair-produced weakly interacting dark-matter candidates, large extra spatial dimensions, and supersymmetric particles in several compressed scenarios.
