Affective De-Commodifying, Economic De-Kinning
In this paper I discuss affective and economic exchanges in commercial surrogacy in the US. I draw on a qualitative study I carried out in the US between 2014 and 2016, consisting of interviews and participant...

Infrared absorption of closely-aligned heterostructures of monolayer and bilayer graphene with hexagonal boron nitride
We model optical absorption of monolayer and bilayer graphene on hexagonal boron nitride for the case of closely-aligned crystal lattices. We show that perturbations with different spatial symmetry can lead to similar absorption...

Using in-plane anisotropy to engineer Janus monolayers of rhenium dichalcogenides
The new class of Janus two-dimensional (2D) transition metal dichalcogenides with two different interfaces is currently gaining increasing attention due to the possibility to access properties different from the typical 2D...
Moiré miniband features in the angle-resolved photoemission spectra of graphene/hBN heterostructures
We identify features in the angle-resolved photoemission spectra (ARPES) arising from the periodic pattern characteristic for graphene heterostructure with hexagonal boron nitride (h BN). For this, we model ARPES spectra...
Microstructures Manufactured in Diamond by Use of Laser Micromachining.

Mar 10, 2020
Different microstructures were created on the surface of a polycrystalline diamond plate (obtained by microwave plasma-enhanced chemical vapor deposition-MW PECVD process) by use of a nanosecond pulsed DPSS (diode pumped solid...
A system for characterisation of piezoelectric materials and associated electronics for vibration powered energy harvesting devices
Self-powered sensor systems that are able to harvest energy from surrounding vibrations are a promising solution for wearable devices, Internet of Things (IoT) and sensing in challenging industrial environments. An automated...
Queer decisions
How does race and location shape the reproductive decisions of gay men who are intended parents? In this article, we propose the concept of strategic racialization to characterize the ways in which gay male parents employ racial...
Gaussian approximation potential modeling of lithium intercalation in carbon nanostructures.
So Fujikake, Volker L Deringer, Tae Hoon Lee, Marcin Krynski, Stephen R Elliott, Gábor Csányi
Feb 27, 2018
We demonstrate how machine-learning based interatomic potentials can be used to model guest atoms in host structures. Specifically, we generate Gaussian approximation potential (GAP) models for the interaction of lithium atoms...
Thermoelectric quantum oscillations in ZrSiS.
Topological semimetals are systems in which conduction and valence bands cross each other and the crossings are protected by topological constraints. These materials provide intriguing tests for fundamental theories, while their...
Asymmetric excitation of left- and right-tail extreme events probed using a Hawkes model
We construct a two-tailed peaks-over-threshold Hawkes model that captures asymmetric self- and cross-excitation in and between left- and right-tail extreme values within a time series. We demonstrate its applicability by...
Valley-polarized tunneling currents in bilayer graphene tunneling transistors
We study theoretically the electron current across a monolayer graphene/hexagonal boron nitride/bilayer graphene tunneling junction in an external magnetic field perpendicular to the layers. We show that change in effective...
Moiré superlattice effects in graphene/boron-nitride van der Waals heterostructures
Van der Waals heterostructures of graphene and hexagonal boron nitride feature a moiré superlattice for graphene's Dirac electrons. Here, we review the effects generated by this superlattice, including a specific miniband...
Case 267.
History A 28-year-old man presented with lifelong anejaculation, which had become an issue because of family planning. The patient had a history of normal erections and experienced the sensation of orgasm without ever...
