    摘要： A method for symbolic model checking for sequential systems using a combination of state-based and state-less approaches. A state-based method is used to compute frontier states by building transition relations on-the-fly using control flow information of the system, and performing successive image computations until a memory bound is reached, and efficiently storing only the new frontier states as disjunctive partitions of Boolean and Arithmetic expressions. A stateless method is used to check reachability of given goal states from a heuristically chosen set of frontier states until depth/time bound is reached. These two methods are alternated until one of the following occurs: all frontier states are explored, all goal states are reached, all computing resources are exhausted. Even though we do not store the entire reachable state set, we guarantee a complete coverage for terminating programs without the need to compute a fixed-point.

    摘要： An additive manufacturing process for forming a metallic layer on the surface of the substrate includes fabricating a substrate from a polymerizable composition by a stereolithographic process, and contacting the reactive surface with an aqueous solution including a metal precursor. The metal precursor includes a metal, and the polymerizable composition includes a multiplicity of multifunctional components. Each multifunctional component includes a reactive moiety extending from a surface of the substrate to form a reactive surface. An interface between the reactive surface and the aqueous solution is irradiated to form nanoparticles including the metal. The nanoparticles are chemically coupled to the reactive surface by reactive moieties, thereby forming a metallic layer on the surface of the substrate.

    摘要： The invention relates to a single-photon counting imaging system and a single-photon counting imaging method. The system comprises a optical filter, a first lens, a digital micro-mirror device (DMD) control system, a second lens, a single-photon counter and a data processing unit, where the DMD together with the first lens and the second lens are used for converting two-dimensional image data into a one-dimensional sequence to complete sampling of measured signals; the ultra-weak light is filtered by the optical filter, after which the ultra-weak light image onto the DMD through the first lens, and the DMD control system controls the probability of the photons reflected to the second lens and the second lens controls the focusing of the photons; and the data processing unit together with the single-photon counter to complete sparse reconstruction, and the data processing unit converts the number of photons counted by the single-photon counter within a certain period of time into the probability of detected photon counts, as the measured value, and a photon density image is reconstructed by adopting an optimization algorithm based on the measurement matrix on the DMD and the measured value, thereby solving out the two-dimensional image.
