We describe some chosen ideas and results for more than 100 years prehistory and history of the remarkable development concerning Hardy-type inequalities. In particular, we present a newer convexity approach, which we believe could partly have changed this development if Hardy had discovered it. In order to emphasize the current very active interest in this subject, we fnalize by presenting some ...

Short-Patch Double Illegitimate Recombination (SPDIR) has been recently identified as a rare mutation mechanism. During SPDIR, ectopic DNA single-strands anneal with genomic DNA at microhomologies and get integrated during DNA replication, presumably acting as primers for Okazaki fragments. The resulting microindel mutations are highly variable in size and sequence. In the soil bacterium Acinetobacter ...

Data-driven machine-learning models offer considerable promise for acoustic source localization. However, many existing models rely on training data that correlates time-of-flight (TOF) measurements with source locations, yet they struggle to handle the complexities arising from nonlinear wave propagation in materials with varying properties. Furthermore, these models overlook the noise and ...

Sampling of the North Sea trawl fishery for lesser sandeel (Ammodytes marinus) showed that 96% of the catch weight consisted of the target species, and experimental sea trials demonstrated that the observed small bycatch percentages of haddock (Melanogrammus aeglefinus), mackerel (Scomber scombrus) and grey gurnard (Eutrigla gurnardus) could be significantly lowered by inserting a netting-based ...

In order to identify relations between mechanical behavior, deformation mechanisms, microstructural properties, and H₂O distribution, Tana‐quartzite samples with added H₂O ranging from 0 to 0.5 wt.% were deformed by axial shortening at constant displacement rates, at 900°C and 1 GPa, reaching up to ∼30% bulk strain. Samples with lower quantities of added H₂O (0.1 ...

Purpose To describe the longitudinal change of health-related quality of life (HRQoL) over 12 months from acute hospitalization in older adults≥70 years (IMMENSE study), and associated factors, to investigate how a medication optimization intervention infuenced this change.<p> <p>Methods The EQ-5D-3L was used at discharge and 1, 6 and 12 months after discharge during a randomized controlled trial ...

This article proposes a framework for stability analysis of hydrogen fuel cell-based hybrid power systems (HPSs) for zero-emission propulsion. An analytical model is developed, and a comprehensive modal analysis is performed to address the HPS dynamic interactions. Sensitivity analysis assesses the impact of operating conditions, control parameters of the governor and converter controllers, and ...

Maternal death (MD) and morbidity are indicators for maternal health and healthcare system development. This PhD project aimed to investigate MD, maternal morbidity, and related risk factors in Georgia using data from the Georgian Birth Registry (GBR) and digital health surveillance systems. Paper I, with a case series design, identified direct and indirect causes of MD from 2014 to 2017. Paper ...

In this paper, I describe the practice of sharing and eating wild meat amongst the Orochen in northeast China, a community of hunters who are no longer allowed to hunt due to state conservation policies. I show how for Orochen meat is the material intermediary between the human and nonhuman worlds, offered to the fire before meals and to animal spirit-masters during hunting. I suggest this demands ...

Textbooks have several important functions in science education. By interviewing six teachers, this study shows how secondary school science teachers perceive and use textbooks as resources, especially in inquiry teaching. The results show that textbooks aid inquiry teaching by offering teachers easily accessible suggestions for practical and inquiry activities in accordance with the curriculum ...
