Chiral orbital-angular-momentum in the surface states of Bi2Se3 [PDF]

open access: yes, 2011
Locking of the spin of a quasi-particle to its momentum in split bands of on the surfaces of metals and topological insulators (TIs) is understood in terms of Rashba effect where a free electron in the surface states feels an effective magnetic field. On

Projected Climatic and Hydrologic Changes to Lake Victoria Basin Rivers under Three RCP Emission Scenarios for 2015–2100 and Impacts on the Water Sector

open access: yesWater, 2019
Rivers in the Lake Victoria Basin support a multitude of ecosystem services, and the economies of the riparian countries (Kenya, Tanzania, Uganda, Rwanda, and Burundi) rely on their discharge, but projections of their future discharges under various ...

Wide‐Field Bond Quality Evaluation Using Frequency Domain Thermoreflectance with Deep Neural Network Feature Reconstruction

open access: yesAdvanced Materials Interfaces, EarlyView.
In this work, wide‐field (>1 mm2) frequency‐domain thermoreflectance (FDTR) hyperspectral imaging is used to image subsurface indium bump bonds 50 µm below the surface. Thermal analysis with Monte Carlo uncertainty propagation is used to evaluate bump quality, while a trained deep neural network (can rapidly reconstruct bump geometry contact area maps.

Global crop yield response to extreme heat stress under multiple climate change futures [PDF]

open access: yes, 2014
Extreme heat stress during the crop reproductive period can be critical for crop productivity. Projected changes in the frequency and severity of extreme climatic events are expected to negatively impact crop yields and global food production. This study

Mode‐dependent Far‐field Radiation of Circularly Polarized Light by a Single Plasmonic Nanohelix

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
The numerical simulations explored the chiroptical response and far‐field radiation behaviors of single plasmonic nanoantennas transitioning into helical structures. This study highlights the ability of these plasmonic nanohelices to regulate the far‐field directionality of radiation power and circular polarization in plasmon‐exciton coupled systems ...

The RCP Stroke Audit Package in Practice

open access: yesJournal of the Royal College of Physicians of London, 1997
This paper describes the use of the Royal College of Physicians 'stroke audit package' in an audit of the care of 156 patients. Recording of history and management compared favourably with that recorded on the RCP database. For a number of items, recording was significantly improved when a locally developed 'checklist', based on the RCP standards, was ...

Global Woody Biomass Harvest Volumes and Forest Area Use Under Different SSP-RCP Scenarios

open access: yesJournal of Forest Economics, 2019
In this study, we investigate the effects of climate change mitigation and socioeconomic development on global forest resources use. The analysis is based on the Global Biosphere Management Model (GLOBIOM), which is a recursive dynamic land-use model ...

The Influence of the Supporting Substrate on Single‐Particle Circular Differential Scattering of DNA Assembled Nanorod Dimers

open access: yesAdvanced Optical Materials, EarlyView.
For most microscopy measurements the sample is placed on a substrate, which causes symmetry breaking, especially relevant for chiral plasmonic nanostructures. DNA origami mediated X‐shaped AuNR dimers showing high structural purity in solution, exhibit significant diversity in lineshapes and signal intensities for their circular differential scattering

Systematic study of high $p_{\rm T}$ hadron production in small collision systems by the PHENIX experiment at RHIC [PDF]

open access: yes, 2017
High $p_{\rm T}$ hadrons in the small systems of $d/^3$He+Au and $p$+Al/Au collisions have been measured at the midrapidity ($|\eta|

Multi-Model Projections of Climate Change in Different RCP Scenarios in an Arid Inland Region, Northwest China

open access: yesWater, 2019
Based on three IPCC (Intergovernmental Panel on Climate Change) Representative Concentration Pathway (RCP) scenarios (RCP2.6, RCP4.5, and RCP8.5), observed meteorological data, ERA-40 reanalysis data, and five preferred GCM (general circulation model ...
