One of the challenges associated with defending against ballistic missiles is to discriminate the object of interest among multiple closely-spaced objects (CSOs) that travel on a ballistic trajectory. The discrimination process typically involves the identification and tracking of the object of interest. One approach that can improve discrimination performance is to employ multiple sensors. Multiple-sensor correlation and discrimination involves the integration of sensor measurements collected...

Since the end of the Korean War, the balance of power in Northeast Asia has been significantly shaped by an enduring Republic of Korea (ROK)-US alliance. Despite the constant threat of a resumption of hostilities between the two Koreas, the current structure maintains a status quo that assures the balance of power in Northeast Asia. However, if hostilities or a collapse of the Democratic Republic of North Korea (DPRK) lead to a unified Korea; its choice of alignment could disrupt the balance 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...

Models of errors during routine sequential action are typically interface-independent. We present here evidence that different task spatial layouts, however, result in different patterns of sequence errors. We explain this data by expanding upon the Memory for Goals framework's activation-based, sequential process to include environmental (such as visual) contextual cues, as well as a richer priming structure. We show a strong qualitative and quantitative fit to experimental data.

Russian aggression in 2014 caught U.S. policy and strategy off guard, forcing reactive measures and reevaluation of the U.S. approach toward Russia. Moscow employed nonlinear methodologies and operated just beneath traditional thresholds of conflict to take full advantage of U.S. and NATO policy and process limitations. In light of this strategic problem, the U.S. Army War College (USAWC), conducted a wargame that revealed four key considerations for future policy and strategy.

The overall goal of the VISION project is to discover neuroprotective strategies in three separate mouse models of injury to the visual axis, in order to identify potential candidates for the treatment of combat eye injuries and preserve vision in our injured warfighters. We have established three different mouse models of ocular injury with different injury- initiating mechanisms (i.e. optic nerve crush, retinal ischemia/reperfusion, and chronic ocular hypertension). We have developed...

The Air Force current operations continue to undergo significant changes compelled by decreasing fiscal appropriations, aging aircraft, and personnel drawdown. The Air Force must effectively improve current maintenance operations in part to deal with these challenges. This study will explore the area of the A-10 aircraft fleet's TF34-100 high-pass turbo-fan engine sensor data to seek its deterioration modelling and prognostics capability. In futurity this will allow for achievement of greater...

This thesis reviews the United States Government strategy to counter proliferation of Weapons of Mass Destruction (WMD). The U.S. strategy to deny adversary WMD capability includes support to international barriers to proliferation, export controls on technology, and reducing threat capabilities. It expresses concern that the U.S. national strategy is too broad and lacks focus for departments and agencies. The paper identifies barriers to proliferation in the strategy that may not prevent...

Laser-driven relativistic electron beams were investigated experimentally and via 3D large-scale plasma simulations. These fast electrons mediate the transfer of energy from the laser to other absorption channels and drive many applications, including bright x-ray and Extreme ultraviolet radiation (EUV or XUV) sources. The investigation was carried out in two phases. In the first phase, reduced mass targets were irradiated with intense ultra-short laser pulses. Bright monochromatic x-rays and...

The legacy international order that the United States and its allies have depended upon for security and prosperity is unraveling. Many U.S. adversaries have adapted their forms of nonconventional warfare to leverage the forces of globalization to amplify their power, while simultaneously neutralizing superior U.S. conventional military power. National security processes and U.S. military doctrine remain trapped in a paradigm designed for a bygone era. This thesis asserts two mutually...

In order to formulate mathematical conjectures likely to be true, a number of base cases must be determined. However, many combinatorial problems are NP-hard and the computational complexity makes this research approach di cult using a standard brute force approach on a typical computer. One sample problem explored is that of finding a minimum identifying code. To work around the computational issues, a variety of methods are explored and consist of a parallel computing approach using Matlab, a...

This monograph offers an outline for educating U.S. and allied service personnel in fundamental human domain skills and argues against their being overlooked in favor of technical solutions. Experience from Afghanistan and Iraq has demonstrated the vital nature of understanding human terrain, with conclusions relevant far beyond counterinsurgency operations in the Islamic world. Any situation where adversary actions are described as irrational demonstrates a fundamental failure in understanding...

A variational data assimilation algorithm is developed for the ocean wave prediction model [Wave Model WAM]. The algorithm employs the adjoint-free technique and was tested in a series of data assimilation experiments with synthetic observations in the Chukchi Sea region from various platforms. The types of considered observations are directional spectra estimated from point measurements by stationary buoys significant wave height (SWH) observations by coastal high-frequency radars (HFRs)...
