Liquid Gripper In article number 2100274, Liang Hu, Yen Wei, Jing Liu, and co-workers present a magnetic liquid gripper based on metallic ferrofluid that enables intimate contact with arbitrarily shaped objects then generates strong adhesion force upon solidification, which can be reversibly eliminated by moderate melting. Through coupling the magnetism of switchable to objects, any non-magneti...

Thermodynamical properties of nuclear matter at sub-saturation densities were investigated using a simple van der Waals-like equation of state with an additional term representing the symmetry energy. First-order isospin-asymmetric liquid-gas phase transition appears restricted to isolated isospin-asymmetric systems while the symmetric systems will undergo fragmentation decay resembling the sec...

Transitional immature B cells undergo apoptosis and fail to proliferate in response to BCR cross-linking, thus representing a target for negative selection of potentially autoreactive B cells in vivo. In agreement with recent reports, transitional B cells were divided into developmentally contiguous subsets based on their surface expression of CD23. When transferred, CD23(+) transitional B cell...

OBJECTIVE To investigate whether transitional incidents can be identified from the medical records of the general practitioners and the hospital and to assess the concordance of transitional incidents between medical records and patient interviews. DESIGN A pilot study. SETTING The study was conducted in 2 regions in the Netherlands: a rural and an urban region. PARTICIPANTS A purposeful ...

BACKGROUND The 3D structure of the atrioventricular conduction axis incorporating detailed cellular and molecular composition, especially that relating to gap-junctional proteins, is still unclear, impeding mechanistic understanding of cardiac rhythmic disorders. METHODS AND RESULTS A 3D model of the rabbit atrioventricular conduction axis was reconstructed by combining histological and immun...
