Abstract:
PROBLEM TO BE SOLVED: To provide a method for etching material at its surface by a focused electronic beam for deriving a chemical reaction on the surface. SOLUTION: The method comprises irradiating the material to be etched by using at least one molecular beam, at least one photon beam and at least one electronic beam in a vacuum atmosphere, exciting the irradiated material and the molecules of the molecular beam so as to induce the prescribed chemical reaction by the compositions of the material and the molecules and to form a reaction product, and removing the reaction product from the surface of the material, i.e., having irradiating and removing steps.

Abstract:
Systems, methods, apparatuses, and computer program products for tracking weak signal traces under severe noise and/or distortions. A method may include tracking at least one candidate frequency trace from a time-frequency representation of a signal. The method may also include identifying a frequency trace of the signal based on tracking results. In addition, the method may include outputting an estimated frequency vector related to the frequency trace. Further, the tracking may be performed under a noisy condition environment.

Abstract:
The present disclosure generally relates to methods of treating hemolytic diseases such as sickle cell anemia using kinase inhibitors, for example, compounds that inhibit the spleen tyrosine kinse (SYK). In some embodiments a method is presented to prevent thrombosis in blood vessels of patients with a hemolytic disease comprising the step of: administrating to a patient having at least one hemolytic disease a therapeutically effective amount of at least one SYK inhibitor. In some embodiments the method includes repeatedly administering the SYK kinase inhibitor to a patient.

In some embodiments, the biosensor comprises a hydrogel comprising alginate. In some embodiments, the biosensor comprises use of a thermophilic bacterial metabolic enzyme immobilized or attached to the hydrogel.
Abstract:
An Explicit Multi-Threading (XMT) system and method is provided for processing multiple spawned threads associated with SPAWN-type commands of an XMT program. The method includes executing a plurality of child threads by a plurality of TCUs including a first TCU executing a child thread which is allocated to it; completing execution of the child thread by the first TCU; announcing that the first TCU is available to execute another child thread; executing by a second TCU a parent child thread that includes a nested spawn-type command for spawning additional child threads of the plurality of child threads, wherein the parent child thread is related in a parent-child relationship to the child threads that are spawned in conjunction with the nested spawn-type command; assigning a thread ID (TID) to each child thread, wherein the TID is unique with respect to the other TIDs; and allocating a new child thread to the first TCU.
Abstract:
A system for assessing lower extremity movement quality includes one or more user sensors, at least one processor, and a movement evaluator implemented using the at least one processor. The movement evaluator is configured, by virtue of appropriate programming, for receiving movement data from the one or more user sensors during a user's performance of a movement task; extracting one or more movement features from the movement data, each movement feature characterizing a respective aspect of a movement pattern of the user's performance that is associated with lower extremity injury risk; and classifying the movement pattern into a classified risk category for lower extremity injury for the user based on the one or more movement features.
Abstract:
Soluble, self-assembling collagens derived from tissues are extensively characterized such that one can predict and customize the final collagen-fibril matrix with respect to fibril microstructure (i.e.,fibril density, interfibril branching), viscoelasticity, and proteolytic degradability. As shown herein these matrices template and direct the deposition of mesoporous silica at the level of individual collagen fibrils. The fibril density, silicic acid concentration, and time of exposure to silicifying solution were varied and the resulting hybrid materials were analyzed by scanning electron microscopy, energy-dispersive x-ray spectroscopy, and rheology. Microstructural properties of the collagen-fibril template are preserved in the silica surface of hybrid materials. Results for three different collagen fibril densities, corresponding to shear storage moduli of 200 Pa, 1000 Pa, and 1600 Pa, indicate that increased fibril density increases the absolute amount of templated silica when all other silica synthesis conditions are kept constant. The mechanical properties of the hybrid material are dominated by the presence of the silica coating rather than the starting collagen matrix stiffness.
Abstract:
Devices, systems, and methods for imaging samples. In some examples, a device includes at least two basins for holding a liquid medium, the at least two basins including a sample chamber and a reservoir. The device includes a wedge between the sample chamber and the reservoir, and the wedge protrudes into the sample chamber and defines a space between the wedge and a bottom of the sample chamber. The space is sized for holding one or more biological samples. The device is formed to define a flow channel between the sample chamber and the reservoir, and the flow channel is shaped to allow the passage of the liquid medium from the sample chamber and the reservoir and to block passage of the one or more biological samples between the sample chamber and the reservoir.
Abstract:
Various communication systems may benefit from optimized delivery or dissemination of information. For example, various wireless networks including heterogeneous wireless may benefit from joint optimization for social content delivery or dissemination over such networks. A method can include selecting content to deliver according to user reward values given wireless capacity constraints. The method can also include delivering the content to a plurality of users via a wireless network comprising different transmission modes.
