Bayesian subcohort selection for longitudinal covariate measurements in follow‐up studies
(Wiley-Blackwell, 2022)
We propose an approach for the planning of longitudinal covariate measurements in follow-up studies where covariates are time-varying. We assume that the entire cohort cannot be selected for longitudinal measurements due ...
Beam Energy and Centrality Dependence of Direct-Photon Emission from Ultrarelativistic Heavy-Ion Collisions
(American Physical Society, 2019)
The PHENIX collaboration presents first measurements of low-momentum (0.41 GeV/c) direct-photon yield dNdirγ/dη is a smooth function of dNch/dη and can be well described as proportional to (dNch/dη)α with α≈1.25. This ...
Beam Energy Scan of Specific Heat Through Temperature Fluctuations in Heavy Ion Collisions
(Institute of Physics Publishing Ltd., 2016)
Temperature fluctuations may have two distinct origins, first, quantum fluctuations
that are initial state fluctuations, and second, thermodynamical fluctuations. We discuss a
method of extracting the thermodynamic ...
Beam Formation Studies on the CERN IS03b H Source
(IOP Publishing, 2022)
An H- ion source is being operated at the new 160 MeV linear injector (Linac4) of the CERN accelerator complex. The source's plasma is of the Radio Frequency Inductively Coupled Plasma type (RF-ICP), without magnetic cusp ...
Bean goose migration shows a long-term temporal shift to earlier spring, but not to later autumn migration in Finland
(BirdLife Finland, 2023)
Ilmastonmuutos vaatii eliöitä mukauttamaan perinnöllisiä tai opittuja käyttäytymismallejaan muuttuviin ympäristöolosuhteisiin. Erityisen alttiita muutoksille voi olla erilaisten habitaattien välillä muuttavat linnut, ...
Beating Darwin-Bragg losses in lab-based ultrafast x-ray experiments
(American Crystallographic Association; American Institute of Physics, 2017)
The use of low temperature thermal detectors for avoiding Darwin-Bragg losses in lab-based ultrafast experiments has begun. An outline of the background of this new development is offered, showing the relevant history and ...
Beauvericin and enniatin B mycotoxins alter aquatic ecosystems : Effects on green algae
(Elsevier, 2024)
Myxotoxins can contaminate algal-based products and arrive to the food chain to consumers producing chronic toxicity effects. Here, we studied phytotoxicity of mycotoxins, beauvericin (BEA) and ennaitin B (ENN B) in four ...
Behaviour of Extractives in Norway Spruce (Picea abies) Bark during Pile Storage
(MDPI AG, 2022)
The current practices regarding the procurement chain of forest industry sidestreams, such as conifer bark, do not always lead to optimal conditions for preserving individual chemical compounds. This study investigates the ...
Behavioural adaptations of argulid parasites (Crustacea: Branchiura) to major challenges in their life cycle
(BioMed Central Ltd., 2015)
Fish lice (Argulus spp.) are obligate ectoparasites, which contrary to most aquatic parasites, retain the ability to swim
freely throughout the whole of their life. In fish farms, they can quickly increase in numbers and ...
Behavioural thresholds of blue tit colour vision and the effect of background chromatic complexity
(Elsevier, 2021)
Vision is a vital attribute to foraging, navigation, mate selection and social signalling in animals, which often have a very different colour perception in comparison to humans. For understanding how animal colour perception ...
