We present a potential solution to the problem of extraction of photogenerated holes from CdS nanocrystals and nanowires. The nanosheet form of C3N5 is a low-band-gap (Eg = 2.03 eV), azo-linked graphenic carbon nitride framework formed by the polymer

A typical approach to reduce speckle in coherent imaging systems is to average same-target images with different speckle realizations. We study settings where such realizations come from applying different transducer-array element weights at receptio

Inorganic semiconductor nanowires and quantum dots made of chalcogenides, III-V semiconductors and halide perovskites offer exciting potential for optoelectronic devices. The orthogonalization possible in nanowires between the normally competing proc

Tin iodide phosphide (SnIP), an inorganic double-helix material, is a quasi-1D van der Waals semiconductor that shows promise in photocatalysis and flexible electronics. However, the understanding of the fundamental photophysics and charge transport

We explore ultrafast photoconductivity dynamics of CdS nanowires wrapped in layers of C 3 N 5 nanosheets using time-resolved terahertz (THz) spectroscopy. We find that nanowire growth, wrapping, and carrier density impact carrier transport in these n

Deep-learning methods have proved successful recently for solving problems in image analysis and natural language processing. One of these methods, convolutional neural networks (CNNs), is revolutionizing the field of image analysis and pushing the s
This book is in the Rapid Communications in Conflict and Security (RCCS) Series (General Editor: Geoffrey R.H. Burn). The character of not only war but also strategic competition appears to be changing. Failing to adapt will result in further losses

We cast a semi-supervised nearest mean classifier, previously introduced by the first author, in a more principled log-likelihood formulation that is subject to constraints. This, in turn, leads us to make the important suggestion to not only investi

An important component in many supervised classifiers is the estimation of one or more covariance matrices, and the often low training-sample count in supervised hyperspectral image classification yields the need for strong regularization when estima
