Experimental investigation of quantum key distribution with position and momentum of photon pairs
, 2005 We investigate the utility of Einstein-Podolsky-Rosen correlations of the position and momentum of photon pairs from parametric down-conversion in the implementation of a secure quantum key distribution protocol.

Advanced Functional Materials, EarlyView.Conjugated polymer–nanocrystal composites are investigated to develop fast, high‐yield green scintillators. The polymer F8BT enables efficient, ultrafast emission, while blends with non‐emitting HfO2 nanocrystals and luminescent CdZnS/ZnS quantum dots reveal distinct sensitization mechanisms.

, 2012 This technical note relates to the theory of cold field electron emission (CFE). It starts by suggesting that, to emphasize common properties in relation to CFE theory, the term 'Lauritsen plot' could be used to describe all graphical plots made with the

Maternal depression and children's adjustment problems : the role of mothers' affective reactivity [PDF]
, 2015 textMothers with depressive symptoms often express more negative emotions than other mothers, react more punitively, and express more frustration (e.g., Belsky, 1984).

Advanced Materials, EarlyView.A high‐capacity polyimide‐linked porous organic polymer (HAT‐PTO) incorporating numerous redox‐active centers is synthesized via a hydrothermal reaction, delivering a high theoretical capacity of 484 mAh g−1. In situ hybridization with carboxyl‐functionalized multiwalled carbon nanotubes enhances conductivity and stability, achieving 397 mAh g−1 at C ...

Optical Engineering, 2018 Direction finding (DF) systems are fundamental electronic support measures for electronic warfare. A number of DF techniques have been developed over the years; however, these systems are limited in bandwidth and resolution and suffer from a complex design for frequency downconversion.

Detectability models for multiple access low-probability-of-intercept networks [PDF]
IEEE Transactions on Aerospace and Electronic Systems, 2000 Increased demands for communications in the tactical battlefield have driven the development of multiple access low-probability-of-intercept (LPI) networks. Most detectability studies of LPI networks focus on the individual links of the network, in which the intercept and detectability calculations are conducted for a single network transmitter.

Infinite-randomness quantum Ising critical fixed points [PDF]
, 1999 We examine the ground state of the random quantum Ising model in a transverse field using a generalization of the Ma-Dasgupta-Hu renormalization group (RG) scheme.

Advanced Materials, EarlyView.This paper introduces a scalable strategy for producing hierarchically aligned PBDT threads through wet‐spinning, controlled drawing, and post‐spinning twisting. Ionic crosslinking reinforces structural stability, whereas alignment and twisting optimize mechanical performance.
