Abstract: Techniques and mechanisms for determining an operation to be performed with a direct memory access (DMA) request. An inspection unit (105) is coupled between an input-output memory management unit (IOMMU) (120) and an endpoint device (118). The inspection unit (105) stores a registry (330) comprising entries (332) which each correspond to a respective address, and a respective one or more resources of the endpoint device (118). A given entry (332) of the registry (330) is created based on a message from the IOM MU (120) which indicates the successful completion of an address translation to facilitate a DMA request. The endpoint device (118) performs a search, based on a DMA request, to determine if any registry (330) entry (332) indicates a combination of an address and an endpoint resource, where said combination matches a corresponding combination indicated by the DMA request. Communication of the DMA request to the IOMMU (120) is contingent on a result of the search.

Abstract: A substrate for epitaxial growth includes a central region that has a center of the substrate and that serves as a non-modified region, and a peripheral region that surrounds the central region in a manner to be spaced apart from the center of the substrate by a distance and that serves as a modified region having a plurality of modified points. A method for manufacturing a substrate for epitaxial growth includes providing a substrate and forming a plurality of modified points in an interior of the substrate in position corresponding to the modified region. A semiconductor device including the substrate and a method for manufacturing the semiconductor device are also disclosed.

Abstract: A polarizer includes a light-transmissible substrate, a plurality of metal wires, and a protective layer. The light-transmissible substrate has a mounting surface. The metal wires are parallelly arranged on the mounting surface of the light-transmissible substrate. Each of the metal wires extends in a direction parallel to the mounting surface, and has an upper surface and a peripheral surface. The protective layer has a first portion and a plurality of second portions. The first portion covers the upper surface of each of the metal wires and is formed into a continuous structure. Each of the second portions covers the peripheral surface of a respective one of the metal wires. Two adjacent ones of the second portions are spaced apart from each other. A light emitting device including the polarizer and a light emitting apparatus including the light emitting device are also disclosed.

Abstract: A patterned substrate includes a substrate body having a surface and a plurality of patterned structures periodically arranged on the surface of the substrate body, where each of the patterned structures includes a first portion formed on the surface of the substrate body, and a second portion formed on the first portion, and where any two adjacent ones of the patterned structures are spaced apart from one another by a minimum distance of not greater than 0.1 ?m. A light-emitting diode includes the patterned substrate and a semiconductor epitaxial structure formed thereon. A process for preparing the patterned substrate and a process for preparing the light-emitting diode are also disclosed.

Abstract: Examples herein relate to a system that includes a first memory device; a second memory device; and an input-output memory management unit (IOMMU). The IOMMU can search for a virtual-to-physical address translation entry in a first table for a received virtual address and based on a virtual-to-physical address translation entry for the received virtual address not being present in the first table, search a second table for a virtual-to-physical address translation entry for the received virtual address, wherein the first table is stored in the first memory device and the second table is stored in the second memory device. In some examples, based on a virtual-to-physical address translation entry for the received virtual address not being present in the second table, a page table walk is performed to determine a virtual-to-physical address translation for the received virtual address. In some examples, the first table includes an IO translation lookaside buffer (IOTLB).

Abstract: Disclosed are novel autoantigens and methods useful in the detection of autoantibodies in persons that have developed, or are at risk of developing, autoimmune hypoparathyroidism. The novel autoantigens of the subject invention may be used to achieve early diagnosis and treatmcnt of autoimmune hypoparathyroidism, and possibly other autoimmune diseases which arc frequently associated with autoimmune hypoparathyroidism.

Abstract: Acquired hypoparathyroidism (AH) occurs frequently as a component of type I autoimmune polyglandular disease (APS-I) or as a sporadic isolated disease in adults. Whereas autoantibodies to the parathyroid glands have been reported in AH, their very existence remains controversial. We report here the detection of autoantibodies as identified through immunoblotting using sera from AH patients. The antibodies were specific to parathyroid autoantigens obtained through differential centrifugation of fresh human hypercellular parathyroid glands, obtained shortly after their surgical removal for tertiary hyperparathyroidism in patients with renal failure. Autoantibodies were detected against several parathyroid specific proteins in the 17 AH sera tested. Twelve (70%) reacted to a protein of 70 kDa, while 16 (94%) reacted to a protein of 80 kDa, and 3 (18%) reacted to a protein of 120-140 kDa, respectively.
