A Modest Proposal for Open Market Risk Assessment to Solve the Cyber-Security Problem
(Virginia Tech, 2016-04-29)
We introduce a model for a market based economic system of cyber-risk valuation to correct fundamental problems of incentives within the information technology and information processing industries. We assess the makeup ...
Towards Optimal Secure Distributed Storage Systems with Exact Repair
Distributed storage systems in the presence of a wiretapper are considered. A distributed storage system (DSS) is parameterized by three parameters (𝑛, 𝑘, 𝑑), in which a file stored across n distributed nodes, can be ...
Environmental Information Improves Robotic Search Performance
(Virginia Tech, 2016)
We address the problem where a mobile search agent seeks to find an unknown number of stationary objects distributed in a bounded search domain, and the search mission is subject to time/distance constraint. Our work ...
Topic model-based mass spectrometric data analysis in cancer biomarker discovery studies
Background: A fundamental challenge in quantitation of biomolecules for cancer biomarker discovery is owing to the heterogeneous nature of human biospecimens. Although this issue has been a subject of discussion in cancer ...
Low Complexity Compression and Speed Enhancement for Optical Scanning Holography
(Nature Publishing Group, 2016-10-06)
Highly stable SERS pH nanoprobes produced by co-solvent controlled AuNP aggregation
(Royal Society of Chemistry, 2016-04-22)
Production of gold nanoparticle (AuNP) surface-enhanced Raman spectroscopy (SERS) nanoprobes requires replicable aggregation to produce multimers with high signal intensity. Herein, we illustrate a novel, yet simple, ...
Acoustofluidic particle trapping, manipulation, and release using dynamic-mode cantilever sensors
(Royal Society of Chemistry, 2016-11-23)
We show here that dynamic-mode cantilever sensors enable acoustofluidic fluid mixing and trapping of suspended particles as well as the rapid manipulation and release of trapped micro-particles via mode switching in liquid. ...
Aggregation and sedimentation of magnetite nanoparticle clusters
(Royal Society of Chemistry, 2016-03-24)
Magnetite nanoparticles are redox active constituents of subsurface and corrosive environments. In this study, we characterized the aggregation and sedimentation behavior of well characterized magnetite nanoparticle clusters ...
A human exposome framework for guiding risk management and holistic assessment of recycled water quality
(Royal Society of Chemistry, 2016-04-12)
Challenges associated with water scarcity and increasing water demand are leading many cities around the globe to consider water reuse as a step towards water sustainability. Recycled water may be used in a spectrum of ...
Long-term performance of a 200 liter modularized microbial fuel cell system treating municipal wastewater: treatment, energy, and cost
(Royal Society of Chemistry, 2016-02-04)
Microbial fuel cells (MFCs) have been intensively studied at a bench scale and the further development of this technology requires system scaling up and understanding of their performance under non-laboratory conditions. ...
