Many potential chemical, biological, radiological, and nuclear (CBRN) terrorism agents lack available medical countermeasures. In 2003, President Bush proposed Project BioShield to address this need. The Project BioShield Act became law in July 2004 (P.L. 108-276). This law has three main provisions: (1) relaxing regulatory requirements for some CBRN terrorism-related spending, including hiring personnel and awarding research grants; (2) guaranteeing a federal government market for new CBRN...

Future requirements may dictate the need for very large spacecraft architectures. At present, the only approach to placing large spacecraft into orbit is use of a heavy lift launch vehicle. But, given the new capabilities demonstrated by NASA's DART, and DARPA's Orbital Express, RASCAL, and FALCON, it is reasonable to envision an alternative means of placing large spacecraft into orbit, that being multiple responsive launches of discrete modules which are later assembled on orbit. An analysis...

Careerism is a phenomenon which most officers deplore. Indeed, the majority would argue that the careerist's inordinate personal ambition has no place in our profession. Yet despite such disapproval, military careerism continues to thrive-a situation which the officer corps today accepts with startling equanimity. 1 Periodic revelations such as the recent embarrassing recruiting irregularities make it impossible for us to close our eyes altogether to the persistence of this affliction. And...

SUMMARY: (1) It was determined that impedance based coating degradation sensors can be successfully used to detect coating failure and assess the performance of CPCs in coastal environments. (2) Laboratory tests showed that the changes associated with coating failure are more pronounced at lower measurement frequencies. (3) The sensitivity of the sensor was found to be dependent on the performance of the CPC; better sensitivity was found in case of better performing CPCs. (4) The changes in...

Using ultrasound as a detection device in the body, including the brain, has been extensively investigated. Unfortunately, previous ultrasound-based methods in the brain have suffered from the severe distortion caused by the skull bone. However, we have recently developed a technique that allows ultrasound to propagate through the skull with significantly reduced distortion, using a shear mode technique. The current project will develop a device for non-invasive identification of the presence...

Emerging evidence suggests that nuclear receptor (NR) coregulators have potential to act as master genes and their deregulation can promote oncogenesis. Proline-, glutamic acid-, and leucine-rich protein-1 (PELP1/MNAR) is a novel NR coregulator. IHC studies using human ovarian cancer tissue arrays (n=123) showed that PELP1/MNAR is 2 to 3 fold over expressed in 60% of ovarian tumors To examine the significance of PELP1/MNAR in ovarian cancer progression, we have generated model cells that over...

The base zone in combat operations refers to an area that is secured against intrusion and attacks from insurgents. During any type of military operation, the number of sensor assets that are available for detecting intrusions are limited. Thus, the size of a base zone is limited by the number of available sensors, and how those sensors are deployed. Depending on the assumptions made in modeling the coverage properties and the terrain of area being covered, the size and shape of the base zone...

When discussing new approaches to the insurgency in Afghanistan, General David Petraeus emphasized that his experiences in Iraq had reinforced the notion that You cannot kill or capture your way out of an insurgency. That statement acknowledges that success for U.S. forces in counterinsurgency operations is the result of a combination of persuasive and coercive measures applied against insurgent organizations and their bases of support. Some of the key principles behind that statement also...

To date, most cancer research has focused on alterations in the sequence, gene structure, copy number and expression of protein coding genes. However, there are increasing studies discovered that a diversity of non-coding RNAs decoded in the genome also playsan essential role in cancer. MicroRNAs (miRNAs), which are small, 21-24nt RNAs generated by the key enzyme Dicer,represent a prominent class of such non-coding RNAs. It has been reported that some miRNAs act as oncogenes to promote tumor...

This work first examines fundamental differences between measurement models established for GPS and those of proposed image-based navigation systems. In contrast to single value per satellite GPS pseudorange measurements, image measurements are inherently angle-based and represent pixel coordinate pairs for each mapped target. Thus, in the image-based case, special consideration must be given to the units of the transformations between the states and measurements, and also to the fact that...

Coronal Mass Ejections (CMEs) have a significant impact on space weather and geomagnetic storms and so have been the subject of numerous studies. Most CME observations have been made while these events are near the sun (e.g.. SOHO/LASCO). Recent data from the Conofo/SMEI and STEREO/SECCHI-HI instruments have imaged CMEs farther into the heliosphere. Analyses of CME observations near the sun measure the properties of these events by assuming that the emission is in the plane of the sky and hence...

A problem exists with current analyses of the Vietnam War, one that can be summed up best as a fascination with the what if theory. Many analysts assume that America's role in that unhappy conflict was reactive from its outset and they have developed the notion that this somehow explains why the United States lost the war. With guilt presumed, they then must simply present the corroborating evidence.

After the terrorist attacks on September 11, 2001, the United States faced a challenge in enlisting the full support of the People's Republic of China (PRC) in the counterterrorism fight against Al Qaeda. This effort raised short-term policy issues about how to elicit cooperation and how to address PRC concerns about the U.S.-led war (Operation Enduring Freedom). Longer-term issues have concerned whether counterterrorism has strategically transformed bilateral ties and whether China's support...

Prostate cancer is the second leading cause of cancer deaths in men in the United States (1). Chinese Red Yeast Rice (RYR) is a traditional food spice consumed throughout Asia (2, 3), and RYR contains a family of monacolins, one of which (monacolin K) is identical in structure to lovastatin, with the ability to inhibit cholesterol synthesis and lower plasma cholesterol levels in humans (4, 5). Since de novo cholesterogenesis is required for tumor growth, RYR may inhibit cancer cell growth....

This thesis research explores integrating a reputation-based trust mechanism with an agent-based backup protection system to improve the performance of traditional backup relay methods that are currently in use in power transmission systems. Integrating agent technology into relay protection schemes has been previously proposed to clear faults more rapidly and to add precision by enabling the use of adaptive protection methods. A distributed, cooperative trust system such as that used in...

Historically, information was a form of power closely guarded, secured, and provided only when there was a need to know. Modern communication equipment and the internet make global news available to anyone who wants it, or wants to provide it. Senior military leaders grew up in the Military during a period when this technology was not a reality. In a very short period of time, typewritten forms were replaced by e-mails and instant messaging. Failing to adapt to the speed at which information...

The major objectives of this proposal are twofold. The first objective is to perform both an experimental and theoretical study of the factors affecting the propagation distance behavior of ultrashort (femtosecond) laser pulses in water. This study will be conducted in the so-called linear regime which involves laser intensities that are below the threshold where nonlinear effects set in. A fundamental problem, which will be resolved by this research, is whether or not the temporal width and...

The on-going War on Terror has brought about the realization that immediate action is required to improve interagency cooperation within amongst the numerous agencies and departments of the USG. In concert with the State Department (DOS), the Defense Department (DoD) must take the lead in improving integrated planning for future operations. The U. S. should abandon ad hoc methodologies where it can and build the architecture required to provide Combatant Commanders (CCDRs) and their subordinate...

Aviation Night Vision Devices (NVDs) are used to enable air operations under conditions of low illumination. The current generation of devices uses a single sensitivity band in either the infrared or near-infrared range. The next generation of such devices may include detectors at more than one absorption band. This has the potential to enhance the segmentation of different surfaces and features in the visual scene. Colour can be used to display contrast between sensor bands. Different schemes...

This paper explores a two-dimensional (2-D) processing approach for co-channel speaker separation of voiced speech. We analyze localized time-frequency regions of a narrowband spectrogram using 2-D Fourier transforms and propose a 2-D amplitude modulation model based on pitch information for single and multi-speaker content in each region. Our model maps harmonically-related speech content to concentrated entities in a transformed 2-D space, thereby motivating 2-D demodulation of the...

We develop a robust method for planning an undersea search by unmanned vehicles; the goal of which is to find groups of objects that may be placed randomly or arranged in predefined patterns on the ocean floor. This approach revolves around the computation of target pattern priors that describe the underlying geometrical structure of the expected group of objects. These priors are updated based on limited search observations, followed by a search performance assessment in the remaining region...

Spatial disorientation mishaps are greater at night and with greater time on task, and sleep deprivation is known to decrease cognitive and overall flight performance. However, the ability to perceive and to be influenced by physiologically appropriate simulated SD conflicts has not previously been studied in an automated simulator flight profile. Methods: A set of 10 flight profiles were flown by 10 U.S. Air Force (USAF) pilots over a period of 28 h in a specially designed flight simulator for...
