Abstract: Methods for the production of ceramic composites in which three-dimensional (3D) printed organic polymer fibers are embedded in an amorphous inorganic ceramic matrix are provided. The composites are made by electrospinning the organic polymer fibers and collecting them in a liquid or gel collector. Ceramic precursors added to the liquid collector after the fibers are collected, or present in the gel collector during the electrospinning, are then cured to form a solid ceramic matrix around the organic polymer fibers to produce an organic polymer fiber-reinforced ceramic.

Abstract: A food product ingredient formed from a keratinous protein-containing material, e.g, feathers, and methods of making the same. The methods include cleaning the keratinous protein-containing material, combining the keratinous protein-containing material with a cereal bran to form a mixture, and hydrolyzing the mixture to form the food product ingredient. Optionally, of the keratinous protein-containing material is cleaned and/or frozen within 5 hours of collection. The methods generate fewer unpleasant odors, and food product ingredients produced by the method can similarly benefit. The food product ingredient may be incorporated into a food product, such as a pet food product.

Abstract: Instruction cache behavior and branch prediction are used to improve the functionality of a computing device by profiling branching instructions in an instruction cache to identify likelihoods of proceeding to a plurality of targets from the branching instructions; identifying a hot path in the instruction cache based on the identified likelihoods; and rearranging the plurality of targets relative to one another and associated branching instructions so that a first branching instruction that has a higher likelihood of proceeding to a first hot target than to a first cold target and that previously flowed to the first cold target and jumped to the first hot target instead flows to the first hot target and jumps to the first cold target.

Abstract: This disclosure provides a solution for improving performance in a virtual machine. In this method, a platform independent intermediate representation of a code segment in an application is obtained from a first virtual machine which is operating on a first platform. The platform independent intermediate representation is generated through a run-time compilation by the first virtual machine. Native code is generated based on the platform independent intermediate representation, in which at least one piece of the native code corresponds to a second platform which is different from the first platform. The at least one piece of the native code is distributed to a second virtual machine which is operating on the second platform.

Abstract: A long-term object tracker employs a continuous learning framework to overcome drift in the tracking position of a tracked object. The continuous learning framework consists of a continuous learning module that accumulates samples of the tracked object to improve the accuracy of object tracking over extended periods of time. The continuous learning module can include a sample pre-processor to refine a location of a candidate object found during object tracking, and a cropper to crop a portion of a frame containing a tracked object as a sample and to insert the sample into a continuous learning database to support future tracking.

Abstract: An example apparatus for generating synthesized images includes a receiver to receive a frame, a mask and external images. The apparatus also includes a foreground augmenter to generate augmented foregrounds in the frame based on the mask. The apparatus includes a background augmenter to generate augmented backgrounds based on the frame, the mask, and the external images. The apparatus also further includes an image synthesizer to generate a synthesized image based on the generated augmented foregrounds and the augmented backgrounds.

Abstract: Aspects of the present disclosure describe techniques for managing locks in just-in-time compiled code in a software application. An example method generally includes profiling locks by during execution of the JIT compiled code. Locks are generally profiled by identifying locks on resources accessed by the JIT compiled code, and recording access information for each of the identified locks. When a safepoint is reached during execution of the JIT compiled code, one or more locks eligible for conversion to a biased lock are identified .based on the recorded access information for each of the identified locks, one or more locks eligible for conversion to a biased lock. Each respective lock of the one or more eligible locks is converted to a biased lock based on a current lock status of the respective lock.

Abstract: This patent pertains to selective inhibition of assembly of the membrane attack complex of complement by use of less than 1 kDa molecular weight forms of the aurin tricarboxylic acid synthetic complex (ATAC), and their derivatives. It further pertains to the use of these materials to treat human conditions where there is evidence of self destruction of host tissue by the membrane attack complex. These diseases include, but are not limited to, Alzheimer disease, age related macular degeneration, and atherosclerosis.
