© Institution of Mechanical Engineers. Finite element model updating is a powerful technique to inversely identify material behaviour. A profound understanding of plastic anisotropy of sheet metal is crucial in controlling complex sheet forming applications through finite element simulations. In this contribution, a generic stereo finite element model updating approach combining stereo digital image correlation and finite element model updating ...

Wildlife must adapt to human presence to survive in the Anthropocene, so it is critical to understand species responses to humans in different contexts. We used camera trapping as a lens to view mammal responses to changes in human activity during the COVID-19 pandemic. Across 163 species sampled in 102 projects around the world, changes in the amount and timing of animal activity varied widely. Under higher human activity, mammals were less ...

Safe storage and utilisation of hydrogen is an ongoing area of research, showing potential to enable hydrogen becoming an effective fuel, substituting current carbon-based sources. Hydrogen storage is associated with a high energy cost due to its low density and boiling point, which drives a high price. Clathrates (gas hydrates) are water-based (ice-like) structures incorporating small non-polar compounds such as H2 in cages formed by hydrogen ...

In recent decades, disappointing poverty trends and welfare state limitations in many European countries – including constraints on minimum income benefits – have paved the way for a larger role of the third sector. An interesting but controversial form of third-sector in-kind support is food aid provision. In Europe, food aid is, so far, a non-rights-based practice displaying worrisome discretionary and stigmatizing characteristics. Yet, the ...

This study explores upright versus inverted catching and crating of spent laying hens. Both catching methods were compared using a cost-benefit analysis that focused on animal welfare, ergonomic, and financial considerations. Data were collected on seven commercial farms (one floor system and six aviary systems) during depopulation of approximately 3,000 hens per method per flock. Parameters such as wing flapping frequency, catcher bird ...

Antithrombotic therapy represents the cornerstone of the pharmacological treatment in patients with acute coronary syndrome (ACS). The optimal combination and duration of antithrombotic therapy is still matter of debate requiring a critical assessment of patient comorbidities, clinical presentation, revascularization modality, and/or optimization of medical treatment. The 2023 European Society of Cardiology (ESC) guidelines for the management of ...

Modern distribution networks are rich in distributed energy resources (DERs) but old in terms of infrastructure and management mentality. This has led to their experiencing more frequent operational issues, leading to distribution system operators (DSOs) facing a key question: should they reinforce or resort to local flexibility markets to solve their issues? The decision ultimately boils down to what the cost of flexibility and value of the ...

In order to tailor treatment to their needs, cancer patients are encouraged to be more active and engaged in their care decisions and to be autonomous yet collaborative with their healthcare professionals when it comes to aspects of their treatment in order to get better results. However, this can only happen after providing them with accurate information about cancer and the different treatment alternatives and their potential side effects. ...

A high level of resistance against power analysis attacks can be achieved with secure circuit styles. All existing secure circuit styles are based on CMOS logic, using both ptype and n-type transistors. However, emerging technologies, such as flexible electronics, achieve optimal price, performance and reliability with n-type-only unipolar logic gates. Therefore, in order to protect chips on flexible foil from power analysis attacks, secure ...
