Abstract: Embodiments of an apparatus and method for assessing non-kinetic weapon performance for negating missile threats are generally described herein. In some embodiments, vulnerabilities of missile threats and techniques for negating the threats are identified. A probability of negation associated with an effectiveness of each of the techniques against the vulnerabilities is calculated. The calculated probability of negation of each technique against each vulnerability are conditioned at a plurality of times associated with a plurality of asymmetric missile defense (AMD) layer elements to produce temporal level probabilities of negation. Each temporal level probabilities of negation are conditioned based on a probability of validation of deployment and a probability of verification of mitigation to produce a battle damage assessment probability of negation.

The retention feature and the tapered protrusion allow for alternate securing means between the top case and the bottom case. As a result, fewer fasteners are required to secure the top case with the bottom case.

Abstract: The present invention provides single sheet and compound para-xylene films for therapeutic uses. For example, the present invention provides single sheet para-xylene films useful as tissue separators and/or adhesion barriers in a subject, where the top and/or bottom surfaces of such films have a water contact angle between 75 and 95 degrees (e.g., to prevent adhesion formation). The present invention also provides compound films composed of at least two para-xylene polymer films with a therapeutic molecule layer in between. Such compound films, when used in vivo (e.g., as a tissue separator and to treat inflammation or atrial fibrillation) allow either therapeutic molecule elution through one of the para-xylene layers, or therapeutic molecule release when the compound film is pierced, such as when it is sutured in place.

Abstract: A method, system and computer program product for automatically detecting and quantifying materials in containers (e.g., luggage, storage containers, equipment or componentry for processing or handling). An X-ray radiograph of a container is generated. A set of materials of interest (e.g., plutonium, steel) is selected to determine if the object comprises or contains materials of interest. An estimate of the areal densities or thicknesses of each of the selected materials of interest is obtained by minimizing an objective function with respect to the areal densities or thicknesses for each of the selected materials of interest. Adaptive regularization is implemented in the objective function to improve optimization results by adding a constraint to the objective function, where the constraint penalizes the objective function for solutions that do not line up with a prior belief about the solution form (e.g., the solution should not be negative or especially noisy).
