Frozen photons in Jaynes Cummings arrays
We study the origin of "frozen" states in coupled Jaynes-Cummings-Hubbard arrays in the presence of losses. For the case of half the array initially populated with photons while the other half is left empty we show the emergence...

Sep 05, 2018
INTRODUCTION: Survival in small cell lung cancer (SCLC) is limited by the development of chemoresistance. Factors associated with chemoresistance in vitro have been difficult to validate in vivo. Both Bcl-2 and β(1)-integrin...
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...

New insights into water splitting at mesoporous α-Fe<sub>2</sub>O<sub>3</sub> films
Thin mesoporous films of α-Fe 2O 3 have been prepared on conducting glass substrates using layer-by-layer self-assembly of ca. 4 nm hydrous oxide nanoparticles followed by calcining. The electrodes were used to study the oxygen...
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...

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...
