Abstract: The use of the electride form of 12CaO-7Al2O3, or C12A7, as a low work function electron emitter in a hollow cathode discharge apparatus is described. No heater is required to initiate operation of the present cathode, as is necessary for traditional hollow cathode devices. Because C12A7 has a fully oxidized lattice structure, exposure to oxygen does not degrade the electride. The electride was surrounded by a graphite liner since it was found that the C12A7 electride converts to it's eutectic (CA+C3A) form when heated (through natural hollow cathode operation) in a metal tube.

Abstract: To provide simple yet accurate stent graft fenestration, a patient-specific fenestration template is used as a guide for graft fenestration. To generate the fenestration template, a patient's medical imaging data such as CT scan data may be used to generate a 3-D digital model of an aorta lumen of the patient. The aorta lumen may encompass one or more branch vessels, which may be indicated on the 3-D digital model. Based on the 3-D digital model or a segment thereof, the fenestration template may be generated, for example, using 3-D printing technology. The fenestration template may include one or more holes or openings that correspond to the one or more branch vessels. To fenestrate a stent graft, the fenestration template is coupled to the stent graft so that the holes or openings on the fenestration template indicate the fenestration locations.

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 for detecting a timing channel in a hardware design includes synthesizing the hardware design to gate level. Gate level information flow tracing is applied to the gate level of the hardware design via a simulation to search for tainted flows. If a tainted flow is found, a limited number of traces are selected. An input on the limited number of traces is simulated to determine whether the traces are value preserving with respect to taint inputs, and to determine that a timing flow exists if the traces are value preserving with respect to the taint inputs.

Abstract: A method for scheduling a random-access communication system having high-priority (HP) and low-priority (LP) nodes is provided, where the scheduling is configured such that the system provides an absolute throughput guarantee for the HP nodes, and a proportional throughput guarantee for the LP nodes. The method is based on obtaining a length of a contention window assigned to an individual node, which is either a HP or a LP node, from a per-slot attempt rate of this individual node. In particular, the attempt rate of each individual node is determined by an algorithm configured such that a resultant sum of the per-slot attempt rates of all the individual nodes is a fixed value independent of the number of the individual nodes. By this scheduling method, the maximum system throughput is approached. The method can be advantageously used in a wireless local area network (WLAN).

Abstract: A method for processing an image of a series of images includes receiving first data representing a first previously reconstructed image and receiving second data representing a second image. A second image is reconstructed in accordance with the first data, the second data and a noise model. The noise model is a likelihood estimation. The second image is reconstructed in accordance with a penalty function. The penalty function is a roughness penalty function. The penalty function is updated by iteratively adjusting an image volume estimate. The penalty function is updated by iteratively adjusting a registration term. The penalty function is a prior image penalty function and the prior image penalty function and a registration term are jointly optimized. The penalty function is determined in accordance with a noise model. The function is a p-norm penalty function.
