Design and rationale of a prospective, randomized, non-inferiority trial to determine the safety and efficacy of the Biolimus A9™ drug coated balloon for the treatment of in-stent restenosis: First-in-man trial (REFORM).

Background: Drug-coated balloon (DCB) angioplasty with paclitaxel-eluting devices is an established treatment for coronary in-stent restenosis (ISR). Biolimus A9™ (BA9), a sirolimus analogue with enhanced lipophilicity, may facilitate enhanced local drug delivery into vascular tissue. A novel DCB coated with Biolimus A9™ represents an alternative to traditional paclitaxel- and sirolimus-coated devices.

Commercial Cu Cr O Decorated with Iron Carbide Nanoparticles as a Multifunctional Catalyst for Magnetically Induced Continuous-Flow Hydrogenation of Aromatic Ketones.

Copper chromite is decorated with iron carbide nanoparticles, producing a magnetically activatable multifunctional catalytic system. This system (ICNPs@Cu Cr O ) can reduce aromatic ketones to aromatic alcohols when exposed to magnetic induction. Under magnetic excitation, the ICNPs generate locally confined hot spots, selectively activating the Cu Cr O surface while the global temperature remains low (≈80 °C).

Tests of General Relativity with GW170817.

The recent discovery by Advanced LIGO and Advanced Virgo of a gravitational wave signal from a binary neutron star inspiral has enabled tests of general relativity (GR) with this new type of source. This source, for the first time, permits tests of strong-field dynamics of compact binaries in the presence of matter. In this Letter, we place constraints on the dipole radiation and possible deviations from GR in the post-Newtonian coefficients that govern the inspiral regime.

Constraining the p-Mode-g-Mode Tidal Instability with GW170817.

We analyze the impact of a proposed tidal instability coupling p modes and g modes within neutron stars on GW170817. This nonresonant instability transfers energy from the orbit of the binary to internal modes of the stars, accelerating the gravitational-wave driven inspiral. We model the impact of this instability on the phasing of the gravitational wave signal using three parameters per star: an overall amplitude, a saturation frequency, and a spectral index.
