Abstract: A ceramic waveguide includes: a doped metal oxide ceramic core layer; and at least one cladding layer comprising the metal oxide surrounding the core layer, such that the core layer includes an erbium dopant and at least one rare earth metal dopant being: lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, thulium, ytterbium, lutetium, scandium, or oxides thereof, or at least one non-rare earth metal dopant comprising zirconium or oxides thereof. Also included is a quantum memory including: at least one doped polycrystalline ceramic optical device with the ceramic waveguide and a method of fabricating the ceramic waveguide.

Abstract: An apparatus to facilitate exception handling for debugging in a graphics environment is disclosed. The apparatus includes load store pipeline hardware circuitry to: in response to a page fault exception being enabled for a memory access request received from a thread of the plurality of threads, allocate a memory dependency token correlated to a scoreboard identifier (SBID) that is included with the memory access request; send, to memory fabric of the graphics processor, the memory access request comprising the memory dependency token; receive, from the memory fabric in response to the memory access request, a memory access response comprising the memory dependency token and indicating occurrence of a page fault error condition and fault details associated with the page fault error condition; and return the SBID associated with the memory access response and fault details of the page fault error condition to a debug register of the thread.

Abstract: An apparatus to facilitate watchpoints for debugging in a graphics environment is disclosed. The apparatus includes processing resources to perform graphics operations using a plurality of threads; and load store pipeline hardware circuitry coupled to the processing resources to: configure a watchpoint register with a value of a watchpoint address, the watchpoint address comprising an address of a memory location in the processor; receive a memory access request from a thread of the plurality of threads; determine, using the watchpoint register, whether the memory access request is requesting access to the watchpoint address; and responsive to the memory access request requesting access to the watchpoint address, return an exception payload to the thread, the exception payload comprising watchpoint details corresponding to the watchpoint address and a scoreboard identifier (SBID) associated with the memory access request.

Abstract: A system for detecting the presence of a target measurand, such as water or specified chemicals which are carried in an aqueous solution, and which includes a fibre-optic probe assembly which incorporates an optical fibre, a thin film of a water swellable hydrogel, and a rigid containment structure. The hydrogel is in contact with the optical fibre such that a volumetric change in the hydrogel causes a microbend of the optical fiber. The microbend is detected by a sensor assembly which is coupled to the probe assembly.

Abstract: A composite material is composed of a matrix of water hardenable material such as a portland-cement-based mixture, and reinforcement consisting of a plurality of layers of open-mesh textile fabric, each layer including two sets of straight lying parallel textile elements united to form the fabric. The width of the elements in each set is preferably chosen so that there is formed within the reinforcement a plurality of irregular cavities extending throughout the thickness of the reinforcement and filled with material of the matrix to form irregular plugs of the matrix material tending to unite the layers of fabric and distribute stresses between them. The individual textile elements may be monofilaments of various cross-sectional form, spun yarns, bundles, rovings, or composite filaments. The elements of the two sets can be united by wearing, weaving, additional yarns or adhesive.
