Author

Jiao, Xiangyu, Li, Haisheng, and Mu, Qiang

Subjects
Mathematics - Quantum Algebra, 17B69, 17B68
Abstract

In this paper, we study Virasoro vertex algebras and affine vertex algebras over a general field of characteristic $p>2$. More specifically, we study certain quotients of the universal Virasoro and affine vertex algebras by ideals related to the $p$-centers of the Virasoro algebra and affine Lie algebras. Among the main results, we classify their irreducible $\mathbb{N}$-graded modules by explicitly determining their Zhu algebras and show that these vertex algebras have only finitely many irreducible $\mathbb{N}$-graded modules and they are $C_2$-cofinite., Comment: 32 pages

Subjects
Mathematics - Quantum Algebra, 17B69, 17B68
Abstract

In this paper, we study contragredient duals and invariant bilinear forms for modular vertex algebras (in characteristic $p$). We first introduce a bialgebra $\mathcal{H}$ and we then introduce a notion of $\mathcal{H}$-module vertex algebra and a notion of $(V,\mathcal{H})$-module for an $\mathcal{H}$-module vertex algebra $V$. Then we give a modular version of Frenkel-Huang-Lepowsky's theory and study invariant bilinear forms on an $\mathcal{H}$-module vertex algebra. As the main results, we obtain an explicit description of the space of invariant bilinear forms on a general $\mathcal{H}$-module vertex algebra, and we apply our results to affine vertex algebras and Virasoro vertex algebras., Comment: 25 pages

13. Heisenberg VOAs over Fields of Prime Characteristic and Their Representations

Author

Li, Haisheng and Mu, Qiang

Subjects
Mathematics - Quantum Algebra, 17B69
Abstract

In this paper, we study Heisenberg vertex algebras over fields of prime characteristic. The new feature is that the Heisenberg vertex algebras are no longer simple unlike in the case of characteristic zero. We then study a family of simple quotient vertex algebras and we show that for each such simple quotient vertex algebra, irreducible modules are unique up to isomorphism and every module is completely reducible. To achieve our goal, we also establish a complete reducibility theorem for a certain category of modules over Heisenberg algebras., Comment: 25 pages

16. On quasi modules at infinity for vertex algebras

Author

Li, Haisheng and Mu, Qiang

Subjects
Mathematics - Quantum Algebra, 17B69
Abstract

A theory of quasi modules at infinity for (weak) quantum vertex algebras including vertex algebras was previously developed in \cite{li-infinity}. In this current paper, quasi modules at infinity for vertex algebras are revisited. Among the main results, we extend some technical results, to fill in a gap in the proof of a theorem therein, and we obtain a commutator formula for general quasi modules at infinity and establish a version of the converse of the aforementioned theorem., Comment: 18 pages

Subjects

Abstract

In this report, silver nanowires (NWs) with different sizes have been obtained by using the poly process synthesis method. As-synthesized samples 1, 2, and 3 with high purity and different sizes have been obtained by changing the amount and kind of inorganic agent in the synthesis procedure. Three samples have been characterized by the scanning electron microscopy (SEM) and powder X-ray diffraction (PXRD). The SEM images of Ag NW 1 (74 nm in diameter, 20–30 μm in length), Ag NW 2 with (60 nm in diameter, 30–40 μm in length), and Ag NWs 3 with (46 nm in diameter, 30–40 μm in length) are obtained. The PXRD results for Ag NWs 1–3 show four typical diffraction peaks at 38.2°, 44.5°, 64.5°, and 77.4°, matching the face-centered cubic lattice for Ag substance and confirming the purity of the Ag NWs sample. In addition, the relative expression of the PTEN and mTOR was determined with real-time RT-PCR at the mRNA level. The content of inflammatory cytokines during stoke was measured with indicated ELISA assay.

25. Infinite-dimensional Hamiltonian Lie superalgebras

Author

Mu, Qiang and Zhang, YongZheng

Abstract

Abstract: The natural filtration of the infinite-dimensional Hamiltonian Lie superalgebra over a field of positive characteristic is proved to be invariant under automorphisms by characterizing ad-nilpotent elements. We are thereby able to obtain an intrinsic characterization of the Hamiltonian Lie superalgebra and establish a property of the automorphisms of the Lie superalgebra.

Abstract

An iterative polynomial fitting method is proposed for the estimate of the baseline of the X-ray fluorescence spectrum signal. The new method generates automatic thresholds by comparing the X-ray fluorescence spectrum signal with the calculated signal from polynomial fitting in the iterative processes. The signal peaks are cut out consecutively in the iterative processes so the polynomial fitting will finally give a good estimation of the baseline. Simulated data and real data from the soil analysis spectrum are used to demonstrate the feasibility of the proposed method.

Abstract

Motivated by a work of Li, we study nonlocal vertex algebras and their smash products over fields of positive characteristic. Through smash products, modular vertex algebras associated with positive definite even lattices are reconstructed. This gives a different construction of the modular vertex algebras obtained from integral forms introduced by Dong and Griess in lattice vertex operator algebras over a field of characteristic zero.

Abstract

Objective To explore effects of resuscitation with different kinds of fluid on liver oxygen free radical in rats with severe hemorrhagic shock. Methods Sixty SD Rats were randomly divided into 5 groups (n=12): control group (C), shock alone group (SA), lactated Ringer's solution (LR)-treatment group, hydroxyethyl starch (HES)-treatment group, 7.2% hypertonic saline-6% HES (HSH)-treated group. According to Wigger's method, the rat model of severe hemorrhagic shock was reproduced. The mean arterial pressure (MAP) was monitored in all the 5 groups. The ALT and AST level in venous blood were determined before shock (Tb), 1h after shock (Ts) and 4h after resuscitation (Td) respectively. In SA group, the rats were sacrificed and the livers were collected at Ts. The rats were resuscitated with LR (3 times the volume of shed blood), HES (1 time the volume of shed blood) and HSH (6ml/kg) in LR, HES and HSH group respectively. The rats in groups C, LR, HES and HSH were sacrificed at Td to obtain the liver tissues. The expression of TNF-α, NF-κB protein, MDA and SOD activities were determined by immunohistochemistry (SP) and chromatometry. The iNOS content was detected by ELISA. The livers were also observed under light microscope and electron microscope for pathological changes. Results Compared with group C, the AST and ALT levels in other groups were significantly higher, the expressions of NF-κB, iNOS and MDA in liver significantly increased, while SOD activity significantly decreased (P＜0.05). The signs of injury were remarkable. The content of cytokines was significantly increased in blood in 3 fluid resuscitation groups compared with group SA (P＜0.05), and signs of tissue injury were also significant. In 3 fluid resuscitation groups, the increase in cytokines was most remarkable in group LR (P＜0.05), and liver tissue injury was also most remarkable, while the cytokine levels were lower (P＜0.05) and pathological changes were also milder in HSH group. Conclusions HSH resuscitation produces loss liver injury after severe hemorrhagic shock by decreasing cytokine production and reducing oxygen free radical-mediated lipid peroxidation.

Abstract

To satisfy more and more complicated requirements on information recording, processing, exchange etc. in newly developed intelligent satellites, a distributed storage system is designed based on SpaceWire network in satellite platform. In this distributed storage system, a SpaceWire router unit serving as the core device of star network connects several nodes, including onboard computers, namely, satellite management unit (SMU), data interface units (DIU) and other nodes like attitude and orbit sensors, space environment monitor instruments and payload controllers, etc. A certain number of standard flash memory modules are separately incorporated into SMU and DIUs to provide comprehensive data recording and exchange service for all nodes in the network. All memory modules are centrally controlled by SMU software to store authorized data in specific type files and retrieve data according to policies set by remote memory access protocol commands. Memory modules that can run in parallel in the distributed storage system produce very high data throughput, which boosts satellite platform capability to a great extent. Backup mechanism among memory modules is deployed and any module can be replaced by others when it meets failure, this makes the storage system robust and reliable. Testing and verification work performed on the distributed storage system shows that the system works quite well and also reveals its attractive effect on improving satellite platform efficiency.
