1064 nm laser-induced defects in pure SiO<sub>2</sub> fibers
We investigate evidence of the formation of nonbridging oxygen hole centers in pure silica photonic crystal fibers from 5 ps 1064 nm pulses. The formation of the defects is attributed to the breaking of stressed silicon-oxygen...
Galaxy shape statistics in the effective field theory
Abstract: Intrinsic galaxy alignments yield an important contribution to the observed statistics of galaxy shapes. The general bias expansion for galaxy sizes and shapes in three dimensions has been recently described by Vlah...

Applying insights from implementation and intervention science to improve the evidence base on image and performance-enhancing drugs (IPEDs) interventions
Recent decades have seen increased public attention devoted to the use of image and performance-enhancing drugs (IPEDs). As research into the epidemiology and aetiology of IPED use has grown substantially, so has interest...

Nov 04, 2019
Harnessing the near-infrared (NIR) region of the electromagnetic spectrum is exceedingly important for photovoltaics, telecommunications, and the biomedical sciences. While thermally activated delayed fluorescent (TADF)...
Electrons and holes in a 40 nm thick silicon slab at cryogenic temperatures
We demonstrate low temperature operation of an electron-hole bilayer device based on a 40 nm thick layer of silicon in which electrons and holes can be simultaneously induced and contacted independently. The device allows the...

Monitoring prisons in England and Wales
NM Padfield
Jan 16, 2017
It is difficult to say whether prison life is ‘well’ supervised by judicial and other legal authorities in England and Wales. This article explores a number of important bodies which all have a role in monitoring what goes on in...
Continuous manufacturing of silver nanoparticles between 5 and 80 nm with rapid online optical size and shape evaluation
Flexible manufacturing technology of nanoparticles with sizes between 5 and 80 nm. This unique size flexibility is enabled by coupling rapid online spectroscopy and a mathematical Mie theory-based algorithm for size and shape...
Unfolding the contents of sub-nm plasmonic gaps using normalising plasmon resonance spectroscopy.

Plasmonic coupling of gold nanoparticles to a gold surface creates intense plasmonic hot spots with large electromagnetic field-enhancements within the cavity formed by the two metallic surfaces. The localised field in such...
A quantum light-emitting diode for the standard telecom window around 1,550 nm.

Dec 18, 2018
During the escalation of the “German Autumn” in 1977 the Federal German government resorted to a specific form of crisis management that had been described as an undeclared state of exception. It was Federal chancellor Helmut...
High-resolution label-free mapping of murine kidney vasculature by raster-scanning optoacoustic mesoscopy

BACKGROUND: Chronic kidney disease (CKD) is a global burden affecting both children and adults. Novel imaging modalities hold great promise to visualize and quantify structural, functional, and molecular organ damage. The aim of...
N-over-N cascode push–pull modulator driver in 130 nm CMOS enabling 20 Gbit/s optical interconnection with Mach-Zehnder modulator
The N-over-N cascode push-pull modulator driver is demonstrated at 20 Gbit/s with IBM 130 nm technology. Electro-optical measurement of the modulator driver integrated with a Mach-Zehnder modulator (MZM) is also presented. This...
Intermittency between avalanche regimes on grain piles.
We experimentally investigate discrete avalanches of grains, driven by a low inflow rate, on an erodible pile in a channel. We observe intermittency between one regime, in which avalanches are quasiperiodic and system spanning...

Artificial light harvesters require ordered arrangement of chromophores. We covalently attach three organic chromophore ligands to silicon dioxide nanoparticles. This allows us to study inter-ligand energy transfer when attached...
Metaphysics, science, and religion
NM Deng
Jan 04, 2017
I found this book interesting and rewarding, as well as a real pleasure to read. It’s a sustained defense of a rather provocative thesis, using original arguments in metaphysics, epistemology, the philosophy of time, space...
Coarsening Dynamics of 2D Subaqueous Dunes
Abstract: Fluid flow over an initially flat granular bed leads to the formation of a surface‐wave instability. The sediment bed profile coarsens and increases in amplitude and wavelength as disturbances develop from ripples into...
