We propose a metric for determining whether one version of a system is more secure than another with respect to a fixed set of dimensions. Rather than count bugs at the code level or count vulnerability reports at the system level, we count a system’s attack opportunities. We use this count as an indication of the system’s “attackability,” likelihood that(More)
The bone morphogenetic proteins (BMPs) are potent osteoinductive factors that accelerate osteoblast maturation, accompanied by increased cell-substrate adhesion. BMP-2 treatment of osteoblastic cells increases phosphorylation of the cytoplasmic BMP-2 signaling molecules, Smad1 and Smad5. We have previously reported that BMP-2 treatment increase cytoskeletal(More)
On August 30, 2005, we successfully demonstrated a large-scale, real-time, surveillance and control application on a wireless sensor network. The task was to track multiple human targets walking through a 5041 square meter sensor field and dispatch simulated pursuers to capture them. We employed a multi-target tracking algorithm that was a combination of a(More)
We fashioned cement disk-shaped spacer models using antibiotic-loaded Palacos and embedded polyethylene and titanium into the surface of half of the models and inoculated the models with methicillin-sensitive Staphylococcus aureus (MSSA), methicillin-resistant S aureus (MRSA), or Staphylococcus epidermidis, and placed them in nutrient broth. Vancomycin was(More)
We study the impact that the liquidity crunch in 2008-2009 had on the U.S. economy’s growth trend. To this end, we propose a model featuring endogenous productivity á la Romer and a liquidity friction á la Kiyotaki-Moore. A key finding in our study is that liquidity declined around the Lehman Brothers’demise, which led to the severe contraction in the(More)
The offshore outsourcing of information technology and information systems (IT/IS) is being increasingly practiced among firms that are focusing on core competencies and cost-effectiveness. With the increase in offshore IT/IS operations, a growing number of companies are encountering negative experiences and unpredicted results. The analysis performed in(More)
BACKGROUND AND OBJECTIVES This article introduces the STTEP (Sustainable Training, Treatment, Employment Program) Model. The Model has been in operation since 1995. It provides a useful conceptual framework for policy makers, practitioners, and educators. The Model evolved from work carried out by chiropractors, myotherapists, and related health workers in(More)
