Huang, Nan-Jing,Zhang, Wen-Bin 한국전산응용수학회 1997 Journal of applied mathematics & informatics Vol.4 No.2

In this paper we introduce and study a new class of completely generalized mildly nonlinear complementarity problems for fuzzy mappings and construct some new iterative algorithms. We also show the existence of solution and the convergence of iterative sequences generated by the algorithm. Our results extend some recent results of Noor, Chang and huang.

Secret Key Generation from Common Randomness over Ultra-wideband Wireless Channels

( Jing Jing Huang ),( Ting Jiang ) 한국인터넷정보학회 2014 KSII Transactions on Internet and Information Syst Vol.8 No.10

We develop a secret key generation scheme using phase estimation in ultra-wideband (UWB) wireless fading channels. Based on the reciprocity theorem, two terminals extract the phase of the channel as a common random source to generate secret bits. Moreover, we study the secret key rate by a pair of nodes observing correlated sources and communicating to achieve secret key agreement over public communication channels. As our main results, we establish a more practical upper bound from Cramer-Rao bound (CRB) and compare it with a universally theoretical upper bound on the shared maximum key rate from mutual information of correlated random sources. Derivation and numerical examples are presented to demonstrate the bound. Simulation studies are also provided to validate feasibility and efficiency of the proposed scheme.

We study the effects of contact shape on ballistic phonon transport in semiconductor nanowires at low temperatures using an approximative scalar model of continuum elasticity. Five different contacts connected to two semiconductor nanowires with different transverse widths are discussed. Numerical results show that the contact shape acts as an ‘acoustic impedance adaptor’, playing a crucial role on the ballistic phonon transmission and thermal conductance. The phonon coupling in the contacts with certain length facilitates ballistic phonon transmission compared to the abrupt interface, in which the phonon scattering is the strongest. It is found that the more the contact is abrupt, the smaller the thermal conductance is. The catenoidal contact rather than the abrupt interface is also the competitive candidate to obtain bigger thermal conductance. These results indicate that choosing an appropriate contact shape is one of the most critical factors to accurately measure the thermal conductance with a very high precision and reliability in different temperature ranges at low temperatures.

Secret Key Generation Using Reciprocity in Ultra-wideband Outdoor Wireless Channels

( Jing Jing Huang ),( Ting Jiang ) 한국인터넷정보학회 2014 KSII Transactions on Internet and Information Syst Vol.8 No.2

To investigate schemes of secret key generation from Ultra-wideband (UWB) channel, we study a statistical characterization of UWB outdoor channel for a campus playground scenario based on extensive measurements. Moreover, an efficient secret key generation mechanism exploiting multipath relative delay is developed, and verification of this algorithm is conducted in UWB Line-of-sight (LOS) outdoor channels. For the first time, we compare key-mismatch probability of UWB indoor and outdoor environments. Simulation results demonstrate that the number of multipath proportionally affects key generation rate and key-mismatch probability. In comparison to the conventional method using received signal strength (RSS) as a common random source, our mechanism achieves better performance in terms of common secret bit generation. Simultaneously, security analysis indicates that the proposed scheme can still guarantee security even in the sparse outdoor physical environment free of many reflectors.

Objective In this research, the influence of breviscapine on anxiety, fear elimination, and aggression and the potential mechanism was investigated. Methods Anxiety and locomotion were analyzed by elevated plus maze and open field test in mice. Bussey-Saksida Mouse Touch Screen Chambers were used to perform fear conditioning. Territorial aggression was assessed by resident intruder test. Protein levels were evaluated by Western blot. Breviscapine improved fear-extinction learning in BALB/cJ mice. Results Breviscapine at 20-100 mg/kg increased center cross number, total distance traveled, and velocity in a dose-dependent manner. On the other hand, breviscapine at 20-100 mg/kg decreased the immobility time in open field test. In addition, breviscapine at 20-100 mg/kg increased the ratio of time on the open arm, time on the distal parts of the open arm, and total distance traveled in elevated plus maze. Breviscapine at 100 mg/kg increased the average attack latency and decreased the number of attacks over the last 3 days of resident intruder test. In hippocampus, protein levels of postsynaptic density protein-95 and synaptophysin were elevated by breviscapine at these three doses. Conclusion The administration of breviscapine alleviates fear extinction, anxiety, and aggression, while increases locomotor in a dose-dependent manner, which might be associated with its influence on synaptic function.

Huang Yuyuan,Dong Lingzhi,Gong Jian,Yang Jing,Lu Shan,Lai Xin-He,Jin Dong,Huang Qianni,Pu Ji,Liu Liyun,Xu Jianguo 한국미생물학회 2022 The journal of microbiology Vol.60 No.10

Two strictly aerobic, Gram-staining-positive, non-spore-forming, regular rod-shaped (approximately 0.7 × 1.9 mm) bacteria (HY170T and HY001) were isolated from bat feces collected from Chongzuo city, Guangxi province (22°20 54 N, 106°49 20 E, July 2011) and Chuxiong Yi Autonomous Prefecture, Yunnan province (25°09 10 N, 102°04 39 E, October 2013) of South China, respectively. Optimal growth is obtained at 25–28°C (range, 4–32°C) on BHI-5% sheep blood plate with pH 7.5 (range, 5.0–10.0) in the presence of 0.5– 1.0% NaCl (w/v) (range, 0–15% NaCl [w/v]). The phylogenetic and phylogenomic trees based respectively on the 16S rRNA gene and 845 core gene sequences revealed that the two strains formed a distinct lineage within the genus Brevibacterium, most closely related to B. aurantiacum NCDO 739T (16S rRNA similarity, both 98.5%; dDDH, 46.7–46.8%; ANI, 91.9–92.1%). Strain HY170T contained MK-8(H2), diphosphatidylglycerol (DPG) and phosphatidylglycerol (PG), galactose and ribose as the predominant menaquinone, major polar lipids, and main sugars in the cell wall teichoic acids, respectively. The meso-diaminopimelic acid (meso-DAP) was the diagnostic diamino acid of the peptidoglycan found in strain HY170T. Anteiso-C15:0 and anteiso-C17:0 were the major fatty acids (> 10%) of strains HY170T and HY001, with anteiso-C17:1A predominant in strain HY170T but absent in strain HY001. Mining the genomes revealed the presence of secondary metabolite biosynthesis gene clusters encoding for non-alpha poly-amino acids (NAPAA), ectoine, siderophore, and terpene. Based on results from the phylogenetic, chemotaxonomic and phenotypic analyses, the two strains could be classified as a novel species of the genus Brevibacterium, for which the name Brevibacterium zhoupengii sp. nov. is proposed (type strain HY170T = CGMCC 1.18600T = JCM 34230T).

Huang, Mei-Juan,Fei, Jing-Jing,Salam, Nimaichand,Kim, Chang-Jin,Hozzein, Wael N.,Xiao, Min,Huang, Hai-Quan,Li, Wen-Jun Springer-Verlag 2016 Archives of microbiology Vol.198 No.8

<P>An actinomycete strain, designated YIM T102(T), was isolated from the rhizospheric soil of Psammosilene tunicoides W. C. Wu et C. Y. Wu collected from Lijiang, Yunnan Province, China. The taxonomic position of the new isolate was investigated by a polyphasic approach. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain YIM T102(T) belongs to the genus Streptomyces. Strain YIM T102(T) was most closely related to Streptomyces eurocidicus NRRL B-1676(T) with a pairwise 16S rRNA gene sequence similarity of 98.9 %. However, DNA-DNA relatedness value between strain YIM T102(T) and S. eurocidicus NBRC 13491(T) was found to be 37.8 +/- 1.8 %. The menaquinone composition detected for strain YIM T102(T) was MK-9 (H-6) and MK-9 (H-8), while the major fatty acids were summed feature 4 (38.0 %), anteiso-C-15:0 (13.1 %), iso-C-16:0 (10.1 %), summed feature 3 (9.8 %) and C-16:0 (9.0 %) and iso-C-15:0 (5.2 %). The whole-cell hydrolysates contained galactose, glucose, ribose and mannose, along with ll-diaminopimelic acid as the diagnostic diamino acid in the peptidoglycan. The DNA G+C content was 70.7 mol%. Strain YIM T102(T) also exhibited antagonistic activity against Alternaria alternata, Alternaria brassicae and Colletotrichum nicotianae Averna, based on the findings from the comparative analyses of phenotypic and genotypic characteristics; it is proposed that strain YIM T102 represents a novel species of the genus Streptomyces, for which the name Streptomyces zhihengii sp. nov. is proposed. The type strain is YIM T102(T) (=KCTC 39115(T) = DSM 42176(T) = CGMCC 4.7248(T)).</P>

Synthesis, characterization, and visible light induced photoactivity of tourmaline-N-TiO2 composite for photooxidation of ethylene

Jing-Hua Tzeng,Chih-Huang Weng,Yu-Hao Lin,Shang-Ming Huang,Li-Ting Yen,Jin Anotai,Yao-Tung Lin 한국공업화학회 2019 Journal of Industrial and Engineering Chemistry Vol.80 No.-

A novel visible light driven tourmaline-nitrogen-doped-TiO2 composite (S-N-TiO2) was prepared using afacile impregnation and sol gel method and its photocatalytic reaction scheme with ethylene wasproposed. X-ray diffraction analysis confirmed the presence of TiO2 in the form of anatase phase. Scanning electron microscope and energy dispersive spectrometer mapping showed that the TiO2particles were deposited and dispersed on the surface of tourmaline. Under visible light irradiation, the SN-TiO2 catalyst containing 4 wt.% tourmaline has higher photocatalytic activity for the oxidation ofethylene than pure TiO2 and N-doped-TiO2 (N-TiO2). This enhanced activity could be not only attributedto the narrowed band gap in visible light driven N-TiO2, but also improved by the spontaneous electricfield of tourmaline which was applied to restrain the recombination of the electron–hole pairs. Thephotogenerated electrons from N-TiO2 were induced by electricfield to react with ethylene, and theleaving photogenerated holes also formed the reactive species. The photocatalytic activity of S-N-TiO2 ismuch affected by synthesis conditions. This novel S-N-TiO2 photocatalyst has a promising perspective inthe gas treatment for air pollution control and horticultural product industries.

Therapeutic and Tumor-specific Immunity Induced by Combination of Dendritic Cells and Oncolytic Adenovirus Expressing IL-12 and 4-1BBL

Huang, Jing-Hua,Zhang, Song-Nan,Choi, Kyung-Ju,Choi, Il-Kyu,Kim, Joo-Hang,Lee, Mingul,Kim, Hoguen,Yun, Chae-Ok Nature Publishing Group 2010 MOLECULAR THERAPY Vol.18 No.2

<P>Recently, gene-based cytokine treatment has been actively pursued as a new promising approach in treating cancer. In an effort to augment the efficiency of antitumor effect by cytokine-mediated immunotherapy, we selected both interleukin (IL)-12 and 4-1BB ligand (4-1BBL) as suitable cytokines to fully activate the type-1 immune response. Coexpression of IL-12 and 4-1BBL mediated by oncolytic adenovirus (Ad) greatly enhanced the antitumor effect. Further, synergistic enhancement in interferon (IFN)-γ levels were seen in mice treated with oncolytic Ad expressing both IL-12 and 4-1BBL. Next, to improve the overall antitumor immune response, we coadministered IL-12- and 4-1BBL-coexpressing oncolytic Ad with dendritic cells (DCs). Combination treatment of IL-12- and 4-1BBL-coexpressing oncolytic Ad and DCs elicited greater antitumor and antimetastatic effects than either treatment alone. Moreover, enhanced type-1 antitumor immune response and higher migratory abilities of DCs in tumors were also observed in the combination arms. The nature of the enhanced antitumor immune response seems to be mediated through the enhanced cytolytic activity of cytotoxic T lymphocytes (CTLs) and IFN-γ-releasing immune cells. Taken together, these data highlight the potential therapeutic benefit of combining IL-12- and 4-1BBL-coexpressing oncolytic Ad with DCs and warrants further evaluation in the clinic.</P>
