A method to implement circuits and circuit elements having one or more ports may include digitizing, using analog-to-digital converters, continuous-time input signals received from one or more ports of a circuit to form discrete-time input signals. At a digital signal processor, the discrete-time input signals are received and the discrete-time input signals are processed to calculate a desired discrete-time output signals. Using digital-to-analog converters, the calculated desired discrete-time output signal are calculated to form outputs of continuous-time output signals at the one or more ports of the circuit. The continuous-time output signals are output to the same one or more ports that receive the continuous-time input signals; and producing, thereby, a desired relationship between the continuous-time output signals and the continuous-time input signals at the one or more ports.

Example photoconductive devices and example methods for using photoconductive devices are described. An example method may include providing a photoconductive device having a metal-semiconductor-metal structure. The method may also include controlling, based on a first input state, illumination of the photoconductive device by a first optical beam during a time period, and controlling, based on a second input state, illumination of the photoconductive device by a second optical beam during the time period. Further, the method may include detecting an amount of current produced by the photoconductive device during the time period, and based on the detected amount of current, providing an output indicative of the first input state and the second input state. The example devices can be used individually as discrete components or in integrated circuits for memory or logic applications.

Many bacteria, including a variety of important human pathogens, are known to respond to various environmental stresses by entry into a novel physiological state, where the cells remain viable, but are no longer culturable on standard laboratory media. On resuscitation from this 'viable but nonculturable' (VBNC) state, the cells regain culturability and the renewed ability to cause infection. It is likely that the VBNC state is a survival strategy, although several interesting alternative explanations have been suggested. This review describes the VBNC state, the various chemical and physical factors known to induce cells into this state, the cellular traits and gene expression exhibited by VBNC cells, their antibiotic resistance, retention of virulence and ability to attach and persist in the environment, and factors that have been found to allow resuscitation of VBNC cells. Along with simple reversal of the inducing stresses, a variety of interesting chemical and biological factors have been shown to allow resuscitation, including extracellular resuscitation-promoting proteins, a novel quorum-sensing system (AI-3) and interactions with amoeba. Finally, the central role of catalase in the VBNC response of some bacteria, including its genetic regulation, is described. © 2010 Federation of European Microbiological Societies Published by Blackwell Publishing Ltd.

Data discovery and data analytics often rely on the use of multiple data sources and data residing in distributed locations. This project builds infrastructure that encourages data-driven discovery from distributed, fragmented datasets without requiring movement of massive amounts of data and without exposing sensitive raw datasets to end users. The capability will be applied to a wide range of science topics: to the large sky surveys of astronomy, for which the collecting instruments are distributed nationally and internationally; to classify Earth science satellite data; for the management of sickle-cell disease and antimicrobial resistance surveillance studies; and to integrate the highly distributed and fragmented data sources needed for multi-hazard mitigation and for sustainable and resilient human-building ecosystem research. The project outlines an ambitious and will enable interdisciplinary training in multiple universities and institutions, and contribute to the training of early career researchers
A Virtual Information-Fabric Infrastructure (VIFI) is created, allowing scientists to search, access, manipulate, and evaluate fragmented, distributed data in the information fabric (the infrastructure to facilitate data sharing) without directly accessing or moving large amounts of data. The system addresses the challenges of coordinating loosely federated infrastructure, distributed data management, security and privacy. The architecture combines a set of loosely coupled components representing some proven capabilities with several emerging components. The VIFI infrastructure includes a novel orchestration layer for on-site analytics and hybrid-infrastructure (GPU, CPU) management, a dynamic secure container-based infrastructure which enables online adaptive analytics from unshareable data at distributed locations, and enhanced data and code management tools. The layer also provides search, access and query based on improvements using persistent identifiers and automated semantic descriptions (or metadata) of raw data using semantic data mining techniques. By integrating several NSF-funded components into a coherent whole, VIFI allows researchers to search, access, manipulate and evaluate data elements without requiring detailed familiarity with the data infrastructure itself. The system contributes to and expands the sets of resources serving diverse communities, and is extensible to additional communities. The project contains a substantial outreach effort, including training of early career scientists.
