Multiparty semiquantum secret sharing based on d-dimensional single-particle states

In this paper, a multiparty semiquantum secret sharing (MSQSS) protocol based on d-dimensional single-particle states is put forward, where the secret key from the sender can be shared among different receivers in such a way that only all receivers cooperate together can they reveal it. This protocol transmits the single particles in a tree-type way. Detailed security analysis turns out that this protocol can successfully resist the outside attack and the participant attack. The protocol has some strengths: (1) it is suitable for the d-dimensional system; (2) it uses d-dimensional single-particle states rather than d-dimensional quantum entangled states as initial quantum resource; (3) it doesn't employ quantum entanglement swapping or unitary operations.Comment: 9 pages, 1 figure, 1 tabl

An Implementation of List Successive Cancellation Decoder with Large List Size for Polar Codes

Polar codes are the first class of forward error correction (FEC) codes with a provably capacity-achieving capability. Using list successive cancellation decoding (LSCD) with a large list size, the error correction performance of polar codes exceeds other well-known FEC codes. However, the hardware complexity of LSCD rapidly increases with the list size, which incurs high usage of the resources on the field programmable gate array (FPGA) and significantly impedes the practical deployment of polar codes. To alleviate the high complexity, in this paper, two low-complexity decoding schemes and the corresponding architectures for LSCD targeting FPGA implementation are proposed. The architecture is implemented in an Altera Stratix V FPGA. Measurement results show that, even with a list size of 32, the architecture is able to decode a codeword of 4096-bit polar code within 150 us, achieving a throughput of 27MbpsComment: 4 pages, 4 figures, 4 tables, Published in 27th International Conference on Field Programmable Logic and Applications (FPL), 201

Spindle oscillations are generated in the dorsal thalamus and modulated by the thalamic reticular nucleus

Spindle waves occur during the early stage of slow wave sleep and are thought to arise in the thalamic reticular nucleus (TRN), causing inhibitory postsynaptic potential spindle-like oscillations in the dorsal thalamus that are propagated to the cortex. We have found that thalamocortical neurons exhibit membrane oscillations that have spindle frequencies, consist of excitatory postsynaptic potentials, and co-occur with electroencephalographic spindles. TRN lesioning prolonged oscillations in the medial geniculate body (MGB) and auditory cortex (AC). Injection of GABA~A~ antagonist into the MGB decreased oscillation frequency, while injection of GABA~B~ antagonist increased spindle oscillations in the MGB and cortex. Thus, spindles originate in the dorsal thalamus and TRN inhibitory inputs modulate this process, with fast inhibition facilitating the internal frequency and slow inhibition limiting spindle occurrence

Bis[4-(2-hy­droxy­benzyl­idene­amino)­benzoato-κO 1]tetra­kis­(methanol-κO)cadmium

In the title mononuclear complex, [Cd(C14H10NO3)2(CH3OH)4], the Cd2+ cation is situated on an inversion centre. It exhibits a distorted octa­hedral coordination, defined by two carboxyl­ate O atoms from two monodentate anions and by four O atoms from four methanol mol­ecules. The crystal structure comprises intra­molecular O—H⋯O and O—H⋯N, and inter­molecular O—H⋯O hydrogen bonds. The latter help to construct a layered structure extending parallel to (100)

Bis(μ-4-amino-3,5-dimethyl-4H-1,2,4-triazole-κ 2 N 1:N 2)bis­(dibromidozinc)

The centrosymmetric dimeric title complex, [Zn2Br4(C4H8N4)2], is isotypic with its [Zn2Cl4(C4H8N4)2], [Zn2I4(C4H8N4)2] and [Co2Cl4(C4H8N4)2] analogues. The zinc atom is bonded to two N atoms belonging to triazole bridging rings and to two terminal bromide ligands, in a geometry close to tetra­hedral. Weak N—H⋯Br hydrogen bonds, with the amine functions as donor groups, are observed in the crystal structure, forming a three-dimensional supra­molecular network

Effects of dietary chromium on growth, amino acid content and proteomic changes in Sea Cucumber Apostichopus japonicus

781-786To assess the effect of dietary chromium, the growth rate, amino acid content and proteomic changes in the sea cucumber Apostichopus japonicus were compared, when fed with the diets amended with chromium-treated (58.27 mg Cr/kg dry weight) Macrocystis pyrifera and a Cr-free control diet (5.83 mg Cr/kg dry weight). After 10 days, the dietary chromium exposure decreased its growth rate and the amino acid content also changed. The proteomic changes were analyzed in A. japonicus after it was fed for 10 days with Cr-added and Cr-free control diet. The total of 1587 proteins were identified, of which 28 proteins were identified as differentially regulated proteins in sea cucumber to Cr stress. Among them, 10 proteins were identified. In summary, this work reported toxic effects in sea cucumber A. japonicus after dietary exposure to Cr

Theoretical study of small signal modulation behavior of Fabry-Perot Germanium-on-Silicon lasers

This work investigated the small signal performance of Fabry-Perot Ge-on-Si lasers by modeling and simulations. The 3dB bandwidth dependence on the structure parameters such as poly-Si cladding thickness, Ge cavity width and thickness, and minority carrier lifetime were studied. A 3dB bandwidth of 33.94 GHz at a biasing current of 270.5 mA is predicted after Ge laser structure optimization with a defect limited carrier lifetime of 1 ns
