Obesity, which induces low-grade inflammation, is a known risk factor for worse prognosis in many cancers including breast. We found that sphingosine-1-phosphate (S1P) produced by sphingosine kinases (SphKs) plays a critical role in obesity-related inflammation and breast cancer. Obesity increased S1P in the tumor microenvironment, as well as in the primary tumors. FTY720, a functional antagonist of S1PR1, dramatically decreased cancer progression by reducing expressions of SphK1 and S1PR1, and...

The Budget Control Act of 2011 along with sequestration is forcing the Department of Defense to reduce expenditures significantly compared to post 9/11 spending. As the Army reduces in strength, so will the civilian workforce at commensurate levels (Tan, 2015). The civilian Defense workforce has been challenged to address proper age diversity as they seek to balance experience with building the bench for tomorrow. The culprit behind this dilemma is due mostly to the hiring restrictions in place...

Our approach considered two applications of ASR: a decision support software system for meetings, in which a summary of a...

Alumina (aluminum oxide, Al2O3) has many favorable properties but is challenging to make transparent because of its anisotropic crystal structure. To combat the anisotropy, magnetic alignment of the particles can be used to minimize the change in index of refraction from grain to grain, thus reducing light scattering and allowing for transparency. Density functional theory results indicated that adding a rare-earth (RE) dopant enhanced the magnetic anisotropy of the alumina crystals, making...

The goal of this research is to increase our understanding of the impact of the ocean and seafloor environmental variability on deep-water (long-range) ocean acoustic propagation and to develop methodologies for including this in acoustic models. Experimental analysis is combined with model development to isolate specific physics and improve our understanding. During the past few years, the physics effects studied have been three-dimensional propagation on global scales, deep water ambient...

As the Alzheimers disease field moves to studies and intervention trials in the preclinical phase and early prodromal period, it will be necessary to measure everyday function in an increasingly more sensitive and sophisticated way to capture more subtle impairments. One approach to increasing sensitivity in functional measures is to use performance based instruments, such as the UCSD Performance-based Skills Assessment (UPSA), in Mild Cognitive Impairment (MCI) or mild Alzheimers disease (AD)...

The noctuid moths, Archanara geminipuncta and A. neurica, were selected as the most promising candidates for biological control of common reed. Successful larval development was only found on Phragmites spp., but development was also possible on the native North American subspecies P. australis subsp. americanus. However, open-field oviposition tests showed a strong preference of females for both European and introduced P. australis. Because of the higher egg mortality on native reed, the...

On the second day of the Gulf War in 1991, U.S. defense officials claimed that air strikes the previous night had dealt a crippling blow to Iraqs small nuclear weapons program, though later analysis would find the program to be much larger than, and not as damaged as, it appeared. In March 1993, the South African government announced that it had not only researched the means to build nuclear weapons, but had in fact constructed a handful of the devices and then voluntarily disassembled them all...
