Role of Atmospheric Indices in Describing Shoreline Variability Along the Atlantic Coast of Europe

open access: yesGeophysical Research Letters, 2023
Beaches are highly variable environments and respond to changes in wave forcing, themselves modulated by climate variability. Here, we analyze three high‐quality beach profile data sets to robustly investigate, for the first time, the link between ...

Experimental study of laser detected magnetic resonance based on atomic alignment [PDF]

open access: yes, 2006
We present an experimental study of the spectra produced by optical/radio-frequency double resonance in which resonant linearly polarized laser light is used in the optical pumping and detection processes.

Making tau amyloid models in vitro: a crucial and underestimated challenge

open access: yesFEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Design of a group oriented, decentralised learning environment [PDF]

open access: yes, 2007
The paper presents the design of a group oriented virtual learning setting where learning takes place in three levels: individual learning, group learning and inter-group communication processes.

The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

The importance of group factors in the delivery of group-based parenting programmes: a process evaluation of Mellow Babies

open access: yesFrontiers in Child and Adolescent Psychiatry
IntroductionThe role of the group has been largely overlooked within evaluations of group-based parenting programmes. Group contextual factors, including size and level of homogeneity, may impact on essential group processes, such as group identification

Advanced intermediate temperature sodium–nickel chloride batteries with ultra-high energy density

open access: yesNature Communications, 2016
Sodium metal halide batteries are attractive technologies for stationary electrical energy storage. Here, the authors report that planar sodium-nickel chloride batteries operated at an intermediate temperature of 190 °C display larger energy densities ...

Effect of cold rolling deformation before intermediate annealing on microstructure and properties of 6A16 aluminum alloy

open access: yesCailiao gongcheng, 2020
Effect of different cold rolling deformations before intermediate annealing on the microstructure and forming properties of 6A16 aluminum alloy sheet during subsequent processing was investigated by means of EBSD and mechanical properties tests.The ...

Covariant Mehler semigroups in Hilbert space [PDF]

open access: yes, 2007
We find necessary and sufficient conditions for a generalised Mehler semigroup to be covariant under the action of a locally compact group. These are then applied to implement "noise reduction" for Hilbert-space valued Ornstein - Uhlenbeck processes ...
