Upconversion photochemistry occurring between palladium(II) octaethylporphyrin (PdOEP, 1) and 9,10-diphenylanthracene (DPA, 2) in toluene successfully sensitizes nanostructured WO(3) photoanodes (E(g) = 2.7 eV) to sub-bandgap non-coherent green photons at low power density.

This paper gives an overview of impersonation bots that generate output in one or possibly, multiple modalities. We also discuss rapidly advancing areas of machine learning and artificial intelligence that could lead to frighteningly powerful new multi-modal social bots. Our main conclusion is that most commonly known bots are one dimensional (i.e., chatterbot), and far from deceiving serious i...

Due to limited energy resources, excessive emission of CO2, global warming, increase of mean temperature, serious impacts have resulted on our living environment, and thus, energy saving and carbon reduction have become urgent issues. Planting grass, flowers and trees can absorb and reduce CO2, thus meeting the requirements for energy saving and carbon reduction in environmental protection. At ...

The AA4871 Spacecraft Design course is the capstone class for the M.S. in Astronautics at the Naval Postgraduate School. Thc design team integrated a Topaz I1 nuclear power system with an EOS Synthetic Aperture Radar to design a low Earth orbit, three axis stabilized satellite flying in a gravity gradient stable orientation. The SAR is a high resolution, electronically stecrable, Earth science ...

The acquisition of a virulence plasmid is sufficient to turn a beneficial strain of Rhodococcus bacteria into a pathogen.

This report presents a software system which enables a person, to play against an artificially intelligent Draughts player, using a physical Draughts board. The software system that is presented uses machine vision techniques to monitor the physical state of a Draughts board, and implements reinforcement learning and classical game playing search techniques to enable the system to learn to play...

In this paper, we introduce a powered Tate pairing on a supersingular elliptic curve that has the same shortened loop as the modified Tate pairing using the eta pairing approach by Barreto et al. The main significance of our approach is to remove the condition which the latter should rely on. It implies that our method is simpler and potentially general than the eta pairing approach, although t...

Powered by gel homas Stossel was lucky he didn’t know how difficult phagocytosis would be to figure out. “If I’d known how complicated it was, I might have gone another way,” he says. In the 18th century, some of the first observations with optical microscopes had shown that cells engulf food and slither along by turning part of their cytoplasm into a semi-solid gel, and then liquefying it agai...
