During the studies supported by our Phase I STTR grant from the US Army, we began developing and testing a novel concept for a probiotic preparation based on naturally occurring bacteriophages as a way to condition the GI tract"s microflora gently and favorably. The preparation (tentatively designated"ShigActive") is a bacteriophage cocktail that specifically targets Shigella spp. (significant ...

There is a current need for an active standoff system that can detect and classify surfaces that have been contaminated with chemical, biological and explosive (CBE) materials. Laser-Induced Breakdown Spectroscopy (LIBS) and Laser Induced Thermal Emission (LITE) has shown great promise for detection of such contaminants. In Phase I of this program we, for the first time, have demonstrated generati ...

ABSTRACT: In Phase II, Syntonics will develop an advanced wireless strain measurement system for structural health monitoring. The system will be configured with a number of passive, non-battery power strain sensors communicating wirelessly with an interrogating device mounted external to the engine under test. The goal is the development of designs and manufacturing processes able to reliably ...

ABSTRACT: We present a comprehensive framework for shaping, inferring, and optimizing information flows for dynamic spectrum access (DSA) in cognitive radio (CR) networks. A principal goal is to develop methods for modeling, design, and analysis of spectrum sensing and control, by leveraging and advancing network coding and network optimization solutions. More specifically, we study spectrum mana ...

ABSTRACT: Providing electrical power for long duration hypersonic flight is a technology that is required to bring about this revolutionary mode of transport. Whether for weapons delivery or for space access, the long duration missions anticipated require a novel approach to the generation of electrical power during flight. Scramjets contain no rotating shafts from which typical generators or mec ...

This STTR phase II proposal addresses AFOSR's task to: "Develop seamless, easy to use, efficient code to calculate electronic wave functions and potential energy surfaces of molecules and predict kinetic rate constants for reactions a priori." This is a long-unsolved problem, fundamental to chemistry, where quantum chemical methods must be extremely accurate to yield reliable rate constants. Yet u ...

The conceptual design of a novel, hypersonic electromagnetic launch system has been developed. Phase-1 assumed a 100-kg projectile leaving the launcher at 7,000 m/sec. The projectile is propelled and levitated by electromagnetic forces inside a tube filled with low pressure helium. A controlled acceleration profile, fully adjustable to the requirements of various missions, is used to reach 5000 ge ...

The development of tractable mathematical models of gradient-frequency nonlinear resonator networks is critical to advanced computer applications that require faithful computer simulation of human attention and/or perception. Conventional linear resonator models are computationally and analytically tractable, however tractability is achieved at the expense of capturing many significant features of ...

An innovative methodology, based on mechanistic models, will be developed for prediction of long-term (25+ years) durability of composites for the US Army's emerging facilities in different climatic zones. Accelerated testing simulating the Army's composites applications in various constructions and fields will validate it. Phase I developed the basic predictive tool using the Arrehenius principle ...

The Air Force Research Lab's Software Protection Initiative has a mission to prevent unauthorized distribution and exploitation of application software critical to national security. That mission has led to investment to develop advanced software protections, including the use of rootkit-like methods that provide anti-piracy and anti-reverse engineering protection critical to software application ...
