In the face of growing anti-access/area denial (A2/AD) challenges, the United States must posture airpower to accomplish missions while under intense and persistent attack. In other words, U.S. air forces must have operational resilience: the capacity to withstand attack, adapt, and generate sufficient combat power to achieve campaign objectives in the face of continued, adaptive enemy action. Although several analytic efforts at RAND and elsewhere have studied selected elements of Air Force...

Access control of information objects is complicated by the need to establish a common set of access requirements, bind those access requirements to the information object, and compute whether or not the criteria are met for allowing access. An information object can be an e-mail, a Word document, a spreadsheet, or a series of sensor readings. In the simplified case, objects that need to be controlled will be stored in an encrypted file. The file will be decrypted when access criteria are...

Applying price indexes presents a challenge in estimating the costs of new defense systems. An inappropriate price index can introduce errors in both development of cost estimating relationships (CERs) and in development of out-year budgets. In this paper we apply two sets of price indexes to the F-35 Joint Strike Fighter procurement program, both to help cost analysts understand the impacts of different price indexes and to provide guidance in their choice. We approach this problem via hedonic...

Current Navy plans call for achieving and maintaining a fleet of 308 ships of certain types and numbers. Some observers have advocated increasing the Navys force-level goal to about 350 ships. The Navy is currently conducting a force structure assessment (FSA), and some observers anticipate that this FSA will lead to a new Navy force-level goal of more than 308 ships, although not necessarily 350 ships. The Navys actual size in recent years has generally been in the range of 270 to 290 ships.

Deep convolutional neural networks (CNNs) detect and classify features of interest in sensory input data. There is a need to investigate how best to implement CNNs for Navy and Department of Defense (DoD) use in platforms with minimal size, weight, and power (SWaP) capacity, since much academic research focuses solely on achieving the highest performance on a specific dataset with minimal concern of compute resources. This report describes a methodology, configuration, and experimental results...

A high-pressure phase of croconic acid is being investigated as a novel energetic material. When pressed at high pressures (5.5 GPa), as-received croconic acid transforms into a beta-phase that is recoverable to ambient conditions. This phase has a higher density and heat of combustion than the as-received material. Rectangular crystals, which are darker than the original powder, can be observed in the recovered material and are thought to indicate formation of the beta-phase. When croconic...

My first introduction to should cost occurred about 5 years ago when holding a nonacquisition billet. This peripheral perspective caused me to reach out to the Defense Acquisition University (DAU) community to learn more. As I recall, one remark about will cost and should cost was that they resembled a kitten with a yarn ballthings would get complex in due course. I chuckled, but I also kept tabs as the next few years passed, and I ended up directly handling should cost for the Air Force Life...

U.S. Army stationing is a constant multi-scale process. Large scale stationing, which is identified with strategic realignments, requires some level of modeling to determine whether the movement of tactical equipment and large numbers of personnel is both economical and continues to meet future long-term strategic requirements. This work explored how climate change implications on water resources may affect military installations in the future, and used that information to outline the WAter...

The U.S. Antarctic Program (USAP) is interested in expanding renewable energy capabilities at McMurdo Station, Antarctica, to reduce costs and emissions. Previous assessments considered wind, solar, and geothermal energy resources but not ocean energy resources such as tidal energy. The National Science Foundation, Division of Polar Programs, Antarctic Infrastructure and Logistics, commissioned the Cold Regions Research and Engineering Laboratory to assess the feasibility of a tidal energy...

A commonly used antifungal, Itraconazol targets a pathway that is also upregulated in human prostate cancer. It was observed that Itraconazol synergizes with cyclopamine to induce superior therapeutic effects. Cyclopamine is toxic, however, when combined with itraconazol the dose requirement for each drug was considerably reduced. This combination therefore has the potential to be more effective and at the same time less toxic. The most important aspect of this finding is that these are...

The objective of the proposed study is to translate SPECT/CT imaging to patients with lower extremity amputation and subsequently evaluate the utility of non-invasive imaging for evaluating the impact of next-generation socket technologies on the health of the residual limb. It is hypothesized that SPECT/CT imaging will provide a highly sensitive, non-invasive tool for clinicians to assess changes in microvascular perfusion elicited by next-generation prosthetic socket technologies and that...

In the past year of the project we have successfully produced recombinant VAR2CSA that binds with high affinity and high specificity to breast cancer cells and breast cancer tissue biopsies. We have demonstrated that the protein binds to distinct secondary modified proteoglycans exclusively present on breast cancer cells and that targeting these with recombinant VAR2CSA interferes with key functions of the cancer cell like growth, migration and invasion.

Our objective was to build, test, and characterize a diver-held ferrous metal detector array with real-time processing algorithms that accurately determines the position, depth, and size of magnetic anomalies from unexploded ordnance (UXO). This was accomplished by using an array of low power, miniature, total field atomic magnetometers, with a new miniaturized electronics design using a novel digital approach. We achieved order of magnitude reductions in the size and power consumption of total...

We propose to complete a Phase II Clinical Trial to demonstrate the safety and efficacy of a fully-implanted neuroprosthesis to provide upper extremity function for individuals with cervical SCI. This study will utilize the networked neuroprosthesis (NNP). The NNP system is completely implanted, including all power, signal processing, stimulus generation, and electrodes. We expect that this advanced system will lead to increased regular use of the neuroprosthesis, with a subsequent positive...
