Instrumental variables: to strengthen or not to strengthen?
Journal of the Royal Statistical Society Series A: Statistics in Society, 2023Abstract Instrumental variables (IVs) are extensively used to handle unmeasured confounding. However, weak IVs may cause problems. Many matched studies have considered strengthening an IV through discarding some of the sample. It is widely accepted that strengthening an IV tends to increase the power of non-parametric tests and ...

Strengthening Aqueous Electrolytes without Strengthening Water
Angewandte Chemie International Edition, 2023AbstractAqueous electrolytes typically suffer from poor electrochemical stability; however, eutectic aqueous solutions—25 wt.% LiCl and 62 wt.% H3PO4—cooled to −78 °C exhibit a significantly widened stability window. Integrated experimental and simulation results reveal that, upon cooling, Li+ ions become less hydrated and pair up with Cl−, ice‐like ...

Much biomedical research is observational. The reporting of such research is often inadequate, which hampers the assessment of its strengths and weaknesses and of a study's generalisability.

Sexual & Reproductive Healthcare, 2012
Pregnant women have varying degrees of awareness of their unborn baby's fitness. A challenge for midwives is to strengthen awareness and use the information from the unborn baby's mother to increase the possibility for a healthy baby to be born. A special kind of mindfulness, here referred to as mindfetalness are suggested to be a concept to use in ...

To develop high-strength Al alloys for selective laser melting (SLM) additive manufacturing, we designed a series of Al-Mg(-Si)-Sc-Zr alloys and additively manufactured them using atomized alloy powders. In the absence of Si, the developed Al-xMg-0.2Sc-0.
