Noncommutative geometry, Quantum effects and DBI-scaling in the collapse of D0-D2 bound states

, 2005
We study fluctuations of time-dependent fuzzy two-sphere solutions of the non-abelian DBI action of D0-branes, describing a bound state of a spherical D2-brane with N D0-branes. The quadratic action for small fluctuations is shown to be identical to that

Self‐Incandescent Heating‐Driven Microstructural Consolidation of Biscrolled Cu/CNT Yarns for Reduced Frequency‐Dependent AC Resistance

Small Methods, EarlyView.
Self‐incandescent heating (SIH) induces microstructural consolidation in biscrolled Cu/CNT yarns, resulting in improved electrical conductivity, a smaller frequency‐dependent increase in AC resistance within the measured range, and stable electrical performance under repeated bending.

Restructuring the Chinese Freight Railway: Two Scenarios

Asia and the Global Economy, 2021
Twenty years of debate regarding the restructuring of the Chinese freight railway have failed to yield a consensus. Early policy statements favoring the creation of above-the-rail competition over a monopoly infrastructure – the “European” model of rail ...

Quasilocal energy for rotating charged black hole solutions in general relativity and string theory [PDF]

, 1999
We explore the (non)-universality of Martinez's conjecture, originally proposed for Kerr black holes, within and beyond general relativity. The conjecture states that the Brown-York quasilocal energy at the outer horizon of such a black hole reduces to ...

Fatigue behaviour of root filled teeth: The role of endodontic sealers and restorative techniques

European Journal of Oral Sciences, EarlyView.
Abstract This in vitro study aimed to evaluate the fatigue behaviour of root canal treated teeth, filled with either AH Plus Jet (AHP) or AH Plus Bioceramic Sealer (AHPB) and rehabilitated with either mesio‐occlusal‐distal (MOD) restorations (direct resin composite) or endocrowns (indirect resin composite).

Post‐Release Survival of the Pelagic Stingray (Pteroplatytrygon violacea, Bonaparte, 1832) in French Longline Fisheries in the Northwestern Mediterranean Sea

Fisheries Management and Ecology, EarlyView.
ABSTRACT Bycatch remains a critical challenge in global fisheries, even when using selective gears such as longlines. In the French longline fishery targeting Atlantic bluefin tuna (Thunnus thynnus) in the Gulf of Lion, the common pelagic stingray (Pteroplatytrygon violacea) is the primary bycatch species.

European railway reforms and efficiency: Review of evidence in the literature

Review of Economic Perspectives, 2017
The objective of the European railway reforms which started in the 1990s was to enable the entry of competition to raise the efficiency of railway transport. This was undertaken because the level of services, particularly in former Eastern Bloc countries,
