Previous research conducted by the RE Mitchell Center for Prisoner of War Studies (REMC) has concluded that optimism proved to be the strongest predictor of health and resilience in a group of Vietnam era Repatriated Prisoners of War (RPWs). Optimism is associated with increased positive psychological health in those afflicted by extreme trauma or illness (Segovia et. al, 2012). In the follow-up study (Segovia et. al, 2015), optimism measured at repatriation was again an excellent predictor of...

Metastatic castration resistant prostate cancer (mCRPC) is clinically treated with both taxane chemotherapy and androgen pathway modulators. Identification of a mediator of resistance across therapy classes is a critically unmet need and would be a significant innovation in the field. Map Kinase Phophatase 1 (MKP-1, DUSP1) is a known regulator of the stress activated protein kinase cascade that can inhibit the activity of pro-apoptotic Map Kinases JNK and p38. It has an established...

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...

Convective rains in the Intertropical Convergence Zone produce lenses of freshened water on the ocean surface. Due to significant density differences between the freshened and saltier seawater, strong pressure gradients develop, resulting in lateral spreading of freshwater lenses in the form of gravity currents. Gravity currents inherently involve three-dimensional dynamics. As a type of organized structure, gravity currents may also interact with, and be shaped by, the ambient oceanic and...

Large-scale Organized Structures (cloud streets and dendritic formations, LOSs) are common in the Marine Boundary Layer (MBL) when wind shear and MBL stability are favorable. We found that the continuous wavelet transform was an effective way to characterize LOSs from in-situ data. Compared to unorganized convection, LOSs enhance exchange with the free troposphere and are more effective at distributing seasalt aerosol throughout the MBL. Since relatively particle-rich updrafts occur under...

A better understanding of the very early times during a detonation event has been difficult to obtain due to the rapid physical and chemical changes that are occurring under non-equilibrium conditions. Direct measurements of events leading up to a detonation are a challenge due to the extreme timescale (100 ps) and highly dynamic environment. A more precise understanding of the excited states, energy flow processes, and chemical reactions at these time scales will lead to better predictive...

In 2016, the federal budget deficit will increase, in relation to the size of the economy, for the first time since 2009, according to the Congressional Budget Offices estimates. If current laws generally remained unchanged, the deficit would grow over the next 10 years, and by 2026 it would be considerably larger than its average over the past 50 years, CBO projects. Debt held by the public would also grow significantly from its already high level. CBO anticipates that the economy will expand...

Recent robotics efforts have led to automating simple, repetitive manipulation tasks to speed up execution and lessen an operator's cognitive load, allowing them to focus on higher level objectives. However, the robot will eventually encounter something unexpected, and if this exceeds the tolerance of automated solutions there must be a way to fall back gracefully to teleoperation. To address this challenge, we present our human-guided autonomy solution in the context of the DARPA Robotics...

Detailed investigations are performed to analyze and mitigate the stability issues encountered in developing a reduced order model (ROM) for combustion response to specified excitations using the Euler equations. The ROM is obtained by employing Galerkins method to reduce the high-order PDEs to a lower-order ODE system by means of POD eigen-bases. Possible solutions of the ROM stability issues by changing and/or by scaling the equation variables are discussed following suggestions from previous...

A new radiation detection method relies on high-energy current (HEC) formed by secondary charged particles in the detector material, which induces conduction current in an external readout circuit. Direct energy conversion of the incident radiation powers signal formation without need for external bias voltage or amplification. The detector is a thin-film multilayer device, composed of alternating disparate electrically conductive and insulating layers. The optimal design of HEC detectors...

Iran ratified the nuclear Nonproliferation Treaty (NPT) in 1970. Article III of the treaty requires non-nuclear-weapon states-parties1 to accept comprehensive International Atomic Energy Agency (IAEA) safeguards; Tehran concluded a comprehensive safeguards agreement with the IAEA in 1974.2 In 2002, the agency began investigating allegations that Iran had conducted clandestine nuclear activities; the IAEA ultimately reported that some of these activities had violated Tehrans safeguards...

The effort developed a comprehensive approach for determining software epistemology which significantly advances the state of the art in automated vulnerability discovery. The approach applies an analytic sieve concept and a novel hashing scheme to a large corpus of open-source software to mine information that indicates the presence of pre- and post-fix conditions in program control flow, fully exploiting the hierarchy of abstraction and richness of data produced by the artifact extraction...

Disinfection kinetics of vegetative cells of Bacillus anthracis in water with free available chlorine ([FAC] 2 mg/L) and monochloramine ([MC] 2 mg/L) were established in this study. FAC disinfection was performed in chlorine demand-free phosphate buffer at pH 7 and 8 at two temperatures (5 and 25 deg. C). MC disinfection was performed in normal phosphate buffer at pH 8 at both temperatures. FAC was more effective than MC in causing cell death, which was more rapid at 25 deg. C than at 5 deg. C...

Tensions between India and Pakistan spiked from 2014 through late 2015, meriting an analysis of how an armed conflict might unfold between the two nuclear-armed neighbors. A common assumption in academic and policy circles is that any modern-day IndoPakistani conflict would remain limited and localized, as nuclear deterrence would dissuade either side from seeking a Carthaginian peace. Accordingly, Indias limited war doctrine, Cold Start, has attracted a great deal of interest and scrutiny...

The primary objective of this experimental study was to investigate the effects of high freestream velocity and an upstream ventilated cavity on the loads generated by a zero-net-mass-flux thruster operating in an aqueous environment. In the absence of freestream flow, averaged thrust increased linearly with frequency, up to a limit imposed by the hardware response time. A simple model was developed that predicts thrust to scale linearly with operating frequency and expelled fluid slug stroke...

This combined report deals with two issues. One is an analysis of the Nunn-McCurdy breach that occurred in the Joint Precision Approach and Landing System Increment1A (JPALS Inc. 1A) acquisition program.1 This particularly ambitious program involved not only the Army, the Navy, and the Air Force but also civilian agencies, and it had international implications because it involved the widely used Instrument Landing System (ILS)a system dating back to the late 1920s that relies on radio beams to...

Over the past year, the number of programs in the Department of Defenses (DOD) portfolio of major defense acquisitions increased from 78 to 79, while DODs total planned investment in these programs decreased from $1.45 trillion to $1.44 trillion. This estimate is in line with a trend seen since 2010 of decreases in the portfolios total acquisition cost. The portfolios cost growth since first full estimates has been substantial, but most of the cost growth occurred 5 or more years ago. The...
