Photocathode Quantum Efficiency of Ultra-Thin Cs2Te Layers On Nb Substrates

open access: yes, 2017
The quantum efficiencies (QE) of photocathodes consisting of bulk Nb substrates coated with thin films of Cs2Te are reported. Using the standard recipe for Cs2Te deposition developed for Mo substrates (220 {\AA} Te thickness), a QE ~11% - 13% at light ...

POSS Polyimide Composite Sealed Triple‐Junction GaAs Thin‐Film Solar Cell for Long‐Term Low Earth Orbit Serve

open access: yesAdvanced Science, EarlyView.
Ultrathin oxide layer and ultraviolet absorbent are introduced into polyhedral oligomeric silsesquioxane (POSS) polyimide to improve the transmittance conservation and realize near zero mass loss against ultraviolet and atomic oxygen exposures. The POSS polyimide composite sealed triple‐junction GaAs thin‐film solar cell exhibits enhanced endurance of ...

Transforming RNA Degradation into Accurate RNA Detection: RNase I–Assisted Rolling Circle Amplification for Clinical Samples

open access: yesAngewandte Chemie, EarlyView.
Here, we transform this otherwise destructive enzymatic activity into a powerful diagnostic advantage through an RNase I–assisted rolling circle amplification (RI‐RCA) strategy. By integrating controlled RNase I–mediated RNA digestion with circular DNA templates, this approach enables direct and highly sensitive detection of target RNA sequences. Using

The Effects of Quantitative Easing Announcements on the Mortgage Market: An Event Study Approach

open access: yesInternational Journal of Financial Studies, 2019
This paper uses event study analysis to estimate the impact of the United States Federal Reserve Bank’s (Fed) quantitative easing (QE) announcements on the mortgage market during the zero lower bound (ZLB) period. A total of 35 QE announcements are

Manipulation of Emergent Collective Excitations via Composition Control in Mixed MPX3 Correlated 2D Antiferromagnets

open access: yesAdvanced Science, EarlyView.
Transition metal and chalcogen substituents are introduced into 2D antiferromagnet, NiPS3, and comprehensive photoluminescence and Raman spectroscopy studies are conducted to investigate how spin orbit entangled exciton and two magnon scattering evolve as functions of substituent concentration.

The Quiet Eye and Motor Expertise: Explaining the “Efficiency Paradox”

open access: yesFrontiers in Psychology, 2018
It has been consistently reported that experts show longer quiet eye (QE) durations when compared to near-experts and novices. However, this finding is rather paradoxical as motor expertise is characterized by an economization of motor-control processes ...

Partial Quantifier Elimination [PDF]

open access: yes, 2017
We consider the problem of Partial Quantifier Elimination (PQE). Given formula exists(X)[F(X,Y) & G(X,Y)], where F, G are in conjunctive normal form, the PQE problem is to find a formula F*(Y) such that F* & exists(X)[G] is logically equivalent to exists(

Gravitational Wavetrains in the Quasi-Equilibrium Approximation: A Model Problem in Scalar Gravitation

open access: yes, 2000
A quasi-equilibrium (QE) computational scheme was recently developed in general relativity to calculate the complete gravitational wavetrain emitted during the inspiral phase of compact binaries. The QE method exploits the fact that the the gravitational
