The research reported here details a fundamental investigation of two modified germanate based glasses with a specific focus on glass stability during thermal-cycling which is representative of the steps required to fabricate a doped micro-structured germanate fiber. The investigations revealed for germanate fibres, surface crystallisation is the dominant loss mechanism, and may explain the poor performance of all published germanate fiber lasers. The research team have found a composition of...

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...

Some problems in the filtering and the detection of diffusion processes that are solutions of stochastic differential equations are studied. Transition densities for Markov process solutions of a large class of stochastic differential equations are shown to exist and to satisfy Kolmogorov's equations. These results extend previously known results by allowing the drift coefficient to be unbounded. With these results for transition densities the nonlinear filtering problem is discussed and the...

This was a study of hot-electron transport, noise, and energy relaxation for doped zinc-oxide and structured ZnO transistor materials with a 2-D electron gas (2DEG) channel subjected to a strong electric field. We conclude that the ZnO 3DEG and 2DEG channels can be operated at the electron density window with better performance than at the off-window electron densities. Models based on the Boltzmann kinetic equation for hot electrons fail to interpret the experimental results unless hot-phonon...

Although there are closed-form solutions for calculating the Probability of False Accept (PFA) and the Probability of False Reject (PFR) of normally distributed measurement errors, there lacks solutions for non-normal distributions. Extending our knowledge to measurement errors that do not follow the normal distribution is beneficial to lowering the risk of having a high PFA or PFR. This research finds that the Uniform Distribution is generally not useful for assessing PFA and PFR.

This final report summarizes the third and final year of a project studying what appears to be an impasse in tribal/federal discourse regarding heritage consultation as currently practiced in the United States. We use Foucault's concept of governmentality to address cultural resource management (CRM) practices for a qualitative study addressing why tensions between tribes and federal agencies arise in heritage discourse, in spite of overlapping goals. Using practice and agency theories and the...

The goal of this project is to fully develop Banach space methods for kernel-based machine learning that extend the Hilbert space framework of regularized learning. We proposed to study Reproducing Kernel Banach Spaces (RKBS) by the semi-inner-product, develop the theory of vector-valued RKBS with applications of RKBS to manifold learning, study frames and Riesz bases for sequence spaces, and construct RKBS with the l1-norm known to enforce sparse solutions. We will also explore classification...

Under static conditions, a system satisfying detailed balance generically relaxes to an equilibrium state in which there are no currents. To generate persistent currents, either detailed balance must be broken or the system must be driven in a time-dependent manner. A stationary system that violates detailed balance evolves to a nonequilibrium steady state (NESS) characterized by fixed currents. Conversely, a system that satisfies instantaneous detailed balance but is driven by the...

An MHD-based model of terrestrial solar wind charge exchange (SWCX) is created and compared to 19 case study observations in the 0.50.7 keV emission band taken from the European Photon Imaging Cameras on board XMM-Newton. This model incorporates the Global Unified Magnetosphere-Ionosphere Coupling Simulation-4 MHD code and produces an X-ray emission data cube from O7 and O8 emission lines around the Earth using in situ solar wind parameters as the model input. This study details the modeling...

Disordered CoFeCrAl and CoFeCrSi0.5Al0.5 alloys have been investigated experimentally and by first-principle calculations. The melt-spun and annealed samples all exhibit Heusler-type superlattice peaks, but the peak intensities indicate a substantial degree of B2-type chemical disorder. Si substitution reduces the degree of this disorder. Our theoretical analysis also considers several types of antisite disorder (Fe-Co, Fe-Cr, Co-Cr) in Y-ordered CoFeCrAl and partial substitution of Si for Al....

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...

Majorana fermions (MFs) are quantum particles that are their own anti-particles, and satisfy non-Abelian exchange statistics. The latter is the key for their potential use in fault-tolerant topological quantum computation. In this project, we proposed to investigate the possibility of realizing MFs in much more physically robust s-wave superfluids by utilizing two additional components: spin-orbit coupling and Zeeman fields. In the last year grant period, we have made the following important...

In light of the central role of inflammation in normal wound repair and regeneration, we hypothesize that the preponderance of human-specific genes expressed in human inflammatory cells is commensurate with the genetic versatility of inflammatory response and the emergence of injuries associated with uniquely hominid behaviors, like a bipedal posture and the use of tools, weapons and fire. The hypothesis underscores the need to study human-specific signaling pathways in experimental models of...

This Coastal and Hydraulics Engineering Technical Note (CHETN) summarizes the environmental benefits that could be gained by restoring sediment continuity from the Kansas River watershed to the Kansas River by passing sediment through, rather than trapping sediment in, large Federal reservoirs. The effort was conducted by the U.S. Army Engineer District, Kansas City (NWK), and supported by the U.S. Army Corps of Engineers (USACE) Regional Sediment Management (RSM) Program. The section of this...

Special Operations Forces (SOF) are routinely exposed to physically demanding missions that result in significant changes in body composition, work capacity, and endocrine function. These changes primarily result from of an energy deficit and sleep deprivation, which are independently known to decrease levels of testosterone. The use of exogenous testosterone has been shown to increase lean body mass (LBM) and muscle function in healthy males and reverse cachexia in diseased populations....
