'Limin Jin' 'Jia Yan'] Oxygen-free high-conductivity copper (OFHC), chromium-zirconium copper (CuCrZr), and Glidcop® AL-15 are widely used in the high heat load absorber elements at the front end of synchrotron radiation facilities. It is necessary to choose the most suitable material according to the actual…

'Zhengxiang Huang' 'Young Gun Ko'] The flow stress of face-centered cubic (FCC) metals exhibits a rapid increase near a strain rate of 104 s−1 under fixed-strain conditions. However, many existing constitutive models either fail to capture the mechanical characteristics of this plastic deformation or use piecewise…

'Sarthak Khandelwal' 'Adwitiya Rao' 'David L. McDowell'] This work presents an open source, dislocation density based crystal plasticity modeling framework, ρ-CP. A Kocks-type thermally activated flow is used for accounting for the temperature and strain rate effects on the crystallographic shearing rate. Slip…

Among the global efforts to directly detect dark matter, the only positive claim so far relies on NaI(Tl) crystal detectors, making this technology of particular interest. ASTAROTH is a project aimed at developing the next generation of such detectors by reading out their scintillation light with SiPM matrices operated…

Continuous developments in Additive Manufacturing (AM) technologies are opening opportunities in novel machining, and improving design alternatives for modern particle accelerator components. One of the most critical, complex, and delicate accelerator elements to manufacture and assemble is the Radio Frequency…

Background Fractures are a major health problem in aging societies. Preventive approaches combining bone health and fall prevention are rare. The osteoporotic fracture prevention program in rural areas (OFRA) is a health care fund-driven program for older people in randomly selected districts in Germany. The components…

SABRE aims to provide a test of the signal observed by DAMA/LIBRA through two separate detectors that rely on joint ultra-high NaI(Tl) purity crystal R&D activities: SABRE South at SUPL Australia and SABRE North at LNGS Italy. SABRE South is designed to disentangle seasonal and site-related effects from the dark…

'Patrick Roigk' 'Kilian Rapp' 'Hans-Helmut König'] Background Fragility fractures are one of the leading causes of disability in older adults. Yet, evidence for effectiveness and cost-effectiveness of preventive approaches combining bone health and fall prevention is rare. Objective To conduct a health-economic…

'Päivi Mäntylä' 'Riitta K. T. Saarela'] Title: Key summary points Aim We investigated the relationship between oral frailty and falls among long-term care residents. Findings Severity of oral frailty did not predict falls. Non-fallers were more often bedridden or needed a wheelchair and were dependent on others for…

Hidden Markov models are a popular choice to extract and examine recurring patterns of activity or functional connectivity in neuroimaging data, both in terms of spatial patterns and their temporal progression. Although many diverse hidden Markov models have been applied to neuroimaging data, most have defined states…

Trifluoroacetic acid (TFA) is a persistent and mobile substance that has been increasing in concentrations within diverse environmental media, including rain, soils, human serum, plants, plant-based foods, and drinking water. Currently, TFA concentrations are orders of magnitude higher than those of other per- and…

Obsessive-compulsive disorder (OCD), marked by intrusive thoughts (obsessions) and repetitive behaviours (compulsions), is linked to dysfunction in frontostriatal circuits. However, neural differences potentially contributing to these alterations are often small, and conflicting evidence obscures the directionality and…

We present a general method for the development of a Δ-DFT-type approach for the calculation of accurate potential energy surfaces (PESs) using a minimal amount (hundreds) of high-level wavefunction theory reference data. The method uses a quasirandom (Sobol) approach to sample points on the PES for which reference…
