Asymptotically cylindrical Calabi–Yau 3–folds from weak Fano 3–folds
We prove the existence of asymptotically cylindrical (ACyl) Calabi–Yau 3–folds starting with (almost) any deformation family of smooth weak Fano 3–folds. This allow us to exhibit hundreds of thousands of new ACyl Calabi–Yau...

Asymptotically cylindrical Calabi-Yau manifolds
Let M be a complete Ricci-flat Kähler manifold with one end and assume that this end converges at an exponential rate to [0, ∞) x X for some compact connected Ricci-flat manifold X. We begin by proving general structure...

The type VI secretion system (T6SS) is crucial in interbacterial competition and is a virulence determinant of many Gram-negative bacteria. Several T6SS effectors are covalently fused to secreted T6SS structural components such...

May 15, 2018
We prove that if two Calabi-Yau invertible pencils have the same dual weights, then they share a common factor in their zeta functions. By using Dwork cohomology, we demonstrate that this common factor is related to a...

Theoretical Study of the Ti-Cl Bond Cleavage Reaction in TiCl4
In this work the kinetics of the TiCl4 <=> TiCl3 + Cl reaction is studied theoretically. A variable-reaction coordinate transition-state theory (VRC-TST) is used to calculate the high-pressure limit rate coefficients. The...

The lithium-argyrodites Li6PS5X (X = Cl, Br, I) exhibit high lithium-ion conductivities, making them promising candidates for use in solid-state batteries. These solid electrolytes can show...
Mono-Acetylenes as New Crosslinkers for All-Carbon Living Charge Carbon Nanotubide Organogels
Nanomaterials, such as single-walled carbon nanotubes (SWCNTs) and graphenes, can be readily gelled using bi- or multi-functional reagents as crosslinkers. This study reports a new reaction of monofunctional acetylenes with...

Order–disorder, ferroelasticity and mobility of domain walls in multiferroic Cu–Cl boracite
Abstract: Domain walls in Cu–Cl boracite develop as a consequence of an improper ferroelastic, improper ferroelectric transition, and have attracted close interest because some are conductive and all can be mechanically written...
Chloride channels are necessary for full platelet phosphatidylserine exposure and procoagulant activity.
Platelets enhance thrombin generation at sites of vascular injury by exposing phosphatidylserine during necrosis-like cell death. Anoctamin 6 (Ano6) is required for Ca(2+)-dependent phosphatidylserine exposure and is defective...
