LiveSec: Towards Effective Security Management in Large-Scale Production Networks (2012)

Network security has become an increasingly important yet challenging issue in present production networks. State-of-the-art solutions cannot meet the overall requirements of high-efficiency security, due to the complicated configuration demands, heavy network traffic and ever-increasing network scale. In this paper, we present Live Sec, a scalable and flexible security management architecture, which achieves holistic security protection with good scalability and flexibility in large-scale networks. Live Sec employs a new Access-Switching layer to provide: 1) interactive policy-enforcement that enables fine-grain control for the end-to-end traffic of network tenants or users, 2) distributed load-balancing that dynamically dispatches security workload over incrementally-deployed security service elements, 3) application-aware network visualization that helps to identify and locate security events, via live traffic monitoring and historical traffic replay. Live Sec has been deployed in Tsinghua University since December 2010. Currently, we are successfully supporting more than 50 users simultaneously (wireless and wired), and over 200 VM-based service elements.
Preparation of a graphitic N-doped multi-walled carbon nanotube composite for lithium–sulfur batteries with long-life and high specific capacity (2016)

One of the challenges for lithium–sulfur batteries is a rapid capacity fading owing to the insulating of sulfur and Li<sub>2</sub>S<sub>2</sub>/Li<sub>2</sub>S compounds, the dissolving and consequent shuttling of polysulfide.
Hologram Formation in Hardened Dichromated Gelatin Films (1969)

Hardened gelatin films sensitized with ammonium dichromate can be utilized to record high quality holograms. The maximum diffraction efficiency of the hologram approaches 90%. The light scattering from the hologram is so low that under ordinary light the hologram plate appears almost indistinguishable from a clear glass plate. Either a transmission or a reflection hologram can be recorded. Linear recording range of light amplitude is large. A practical method of preparing and processing the film is described, and the exposure characteristics are presented.
Fast stitching of videos captured from freely moving devices by exploiting temporal redundancy (2010)

We investigate the problem of efficient panoramic video construction based on time-synchronized input video streams. No additional constraints are imposed regarding the motion of the capturing video cameras. The presented work is, to the best of our knowledge, the first attempt to construct in real-time a panoramic video stream from input video streams captured by freely moving cameras. The main contribution is in proposing an efficient panoramic video construction algorithm that exploits temporal information to avoid solving the stitching problem fully on a frame by frame basis. We provide detailed experimental evaluation of different methodologies that employ previous frames stitching results such as tracking interest points using optical flow and using areas of overlap to limit the search space for interest points. Our results clearly indicate that making use of temporal information in video stitching can achieve a significant reduction in execution time while providing a comparable effectiveness.
High performance single-grain Ge TFTs without seed substrate (2010)

On the Alloy Layers formed by the Reaction between Ferrous Alloys and Molten Aluminium (1978)

Commercial pure Fe, Fe-Si, Fe-Cr, Fe-Ni, Fe-Cu, Fe-Mn and Fe-C alloys were dipped into molten aluminium (99.8%Al) at 700, 750 and 800°C for various times. The alloy layers formed were examined by X-ray and EPMA analysis, and the hardness and thickness of the alloy layers were also measured. The alloy layer formed on each ferrous alloy is mainly composed of FeAl3 and Fe2Al5, and much FeAl3 is near the adhered aluminium and no FeAl3 near the base metal. Fe2Al5 occupies the major portion of the alloy layer. For commercial pure Fe, Fe-Si, Fe-Cr, Fe-Ni and Fe-Mn alloys, the Fe-Al solid solution exists inside the Fe2Al5 layer. The alloying elements in the base metal reduce the thickness of the alloy layers, especially Si, Ni and Cu. The alloy layers formed on commercial pure Fe, Fe-Si, Fe-Cr, Fe-Ni, Fe-Mn and Fe-Cu alloys are tongue-like and that formed on Fe-C alloy is band-like. In the latter case, however, a slightly tongue-like shape appeares at lower temperatures. The hardness of each alloy layer near the base metal is higher than that near the adhered aluminium. The alloy layer formed on the Fe-C alloy is a little harder than that on the other alloys.
Joint training of DNNs by incorporating an explicit dereverberation structure for distant speech recognition (2016)

We explore joint training strategies of DNNs for simultaneous dereverberation and acoustic modeling to improve the performance of distant speech recognition. There are two key contributions. First, a new DNN structure incorporating both dereverberated and original reverberant features is shown to effectively improve recognition accuracy over the conventional one using only dereverberated features as the input. Second, in most of the simulated reverberant environments for training data collection and DNN-based dereverberation, the resource data and learning targets are high-quality clean speech. With our joint training strategy, we can relax this constraint by using large-scale diversified real close-talking data as the targets which are easy to be collected via many speech-enabled applications from mobile internet users, and find the scenario even more effective. Our experiments on a Mandarin speech recognition task with 2000-h training data show that the proposed framework achieves relative word error rate reductions of 9.7 and 8.6 % over the multi-condition training systems for the cases of single-channel and multi-channel with beamforming, respectively. Furthermore, significant gains are consistently observed over the pre-processing approach using simply DNN-based dereverberation.
Effective operation and performance improvement methods for OMTP BONDI-based mobile Web widget resources (2011)

The Open Mobile Terminal Platform (OMTP) is a global forum made by telecommunications providers to promote user-oriented mobile services and data businesses. Devised by OMTP, BONDI is a browser-based application or a mobile Web run-time platform to help widgets make good use of the functions of mobile devices in a secure way. BONDI enables applications programmed with Web standard technologies such as HTML, JavaScript, CSS, and AJAX to reach the internal functions of mobile devices. Since BONDI, which is not just a simple network application, can reach the internal resources of devices in standard ways, it enables the application and widgets to be developed regardless of the operating system (OS) or platform. Web browser-based widgets are vulnerable to the network environment, and their execution speed can be slowed as the operations of the widgets or applications become heavy. Compared with the native widgets inside the device, however, those Web widgets will be continuously used thanks to the user-friendly simple interface and the faster speed in using Web resources. This study deals with a method to effectively operate and manage the resources of OMTP BONDI Web widget and provides improved results based on running performance evaluation experiments. The experiments were carried out to improve the entire operating time by enhancing the module-loading speed. In this regard, only indispensable modules were allowed to be loaded while the BONDI widget was underway. For this purpose, the widget resource list, which can make the operating speed of the BONDI widget faster, was redefined while a widget cache was employed. In addition, the widget box, a management tool for removed widgets, was devised to store temporarily idle widgets.
A Facile Route to Isotropic Conductive Nanocomposites by Direct Polymer Infiltration of Carbon Nanotube Sponges (2011)

Fabrication of high-performance nanocomposites requires that the nanoscale fillers be dispersed uniformly and form a continuous network throughout the matrix. Direct infiltration of porous CNT sponges consisting of a three-dimensional nanotube scaffold may provide a possible solution to this challenge. Here, we fabricated CNT sponge nanocomposites by directly infiltrating epoxy fluid into the CNT framework while maintaining the original network structure and CNT contact, with simultaneous improvement in mechanical and electrical properties. The resulting composites have an isotropic structure with electrical resistivities of 10 to 30 Ω·cm along arbitrary directions, much higher than traditional composites by mixing random CNTs with epoxy matrix. We observed reversible resistance change in the sponge composites under compression at modest strains, which can be explained by tunneling conduction model, suggesting potential applications in electromechanical sensors.
Induction of primary anti‐viral cytotoxic T cells by <i>in vitro</i> stimulation with short synthetic peptide and interleukin‐7 (1992)

The present study investigated whether a short synthetic peptide NPP, with a modified sequence (147-158 R156-) derived from influenza A virus nucleoprotein with high affinity for Kd major histocompatibility complex class I molecules, could induce primary influenza virus-specific cytotoxic T (Tc) cells in vitro. Naive BALB/c (H-2d) splenocytes did not respond to the stimulation with only NPP with the generation of effector Tc cells specific for influenza A virus-infected target cells in vitro. However, they were able to do so if cultured with NPP in the presence of IL-7. IL-7 activity in this system differed significantly from IL-2 activity in the specificity of the effect. The use of exogenous IL-2, instead of IL-7, with NPP resulted in the induction of lytic cells that lysed both influenza virus-infected and uninfected syngeneic target cells. These results suggest that IL-7 is a potent regulatory cytokine in the antigen-specific activation of resting naive Tc cell precursors and may provide the necessary conditions for the induction of human primary Tc cells in vitro.
BT-201: INVESTIGATION OF THE SPIDER WEB FOR ANTIBACTERIAL ACTIVITY (2012)

Spiders build their webs with a material called silk. Spider silk contain protein fiber that have many advantages and functions. One of them is to capture their prey such as flies, insects, and others. The needs on the research of antibacterial activity are important for human health because of importance of finding a new cure for some diseases that occur because of microorganisms. Some of the microorganisms, especially bacteria are becoming resistant to many antibacterial agents. The purpose of this new investigation was to determine if spider webs exhibit antibacterial properties. In order to determine antibacterial properties, the spider webs were extracted using different solvents such as methanol, ethanol, acetone, and water in different conditions (extraction time, and concentration used for optimization). These extracts were screened for antibacterial activity using disc diffusion assay. Two bacteria were used in the antibacterial assay namely Bacillus subtilis, and Escherichia coli. The determination of spider webs exhibiting antibacterial properties was based, at least in this study, solely upon the definite appearance of inhibition zone around the well of plates. In screening, acetone solvent was shown the best for antibacterial activity compare to other solvents with 10 mm of diameter of inhibition zone for Bacillus subtilis and 9 mm of diameter of inhibition zone for Escherichia coli. In optimization, the maximum inhibition zone on the Bacillus subtilis was 15 mm at a time of 48 hours and concentration of 0.035 g/ml. Meanwhile, the maximum diameter of inhibition zone on the Escherichia coli was 12 mm at a time of 48 hours and concentration of 0.035 g/ml. Therefore, this study showed that spider webs could be potential source of new antibacterial agents.
Cysteine-Scanning Mutagenesis of Transmembrane Domain XII and the Flanking Periplasmic Loop in the Lactose Permease of <i>Escherichia coli</i> (1996)

Using a functional lactose permease mutant devoid of Cys residues (C-less permease), each amino acid residue in transmembrane domain XII and the periplasmic loop between putative helices XI and XII (loop XI/XII) was replaced individually with Cys. Out of 34 mutants, 31 exhibit 60-100% or more of C-less activity, mutants Gly377-->Cys and Leu385-->Cys exhibit lower rates of transport but accumulate lactose about 60-70% as well as C-less, and mutant Leu400-->Cys exhibits < 20% of C-less activity. Immunoblots reveal that all of the mutant proteins are present in the membrane in amounts comparable to that of C-less with the exception of mutants Gly377-->Cys and Leu385-->Cys which are expressed about 40% as well as C-less and mutant Leu400-->Cys which is hardly detectable. When transferred to the wild-type background, however, mutant Leu400-->Cys is expressed normally and exhibits highly significant transport activity. Finally, each active Cys-replacement mutant was assayed for sensitivity to N-ethylmaleimide, and with three exceptions, the mutants are essentially unaffected by the alkylating agent. Mutants Val367-->Cys, Gly370-->Cys, and Tyr373-->Cys which are predicted to be immediately distal to helix XI in loop XI/XII are significantly inactivated. The periodicity observed suggests that the periplasmic end of transmembrane domain XI may extend to position 373. In the following paper [Voss, J., He, M. M., Hubbell, W. L., & Kaback, H. R. (1996) Biochemistry 35, 12915-12918], site-directed spin labeling of single-Cys mutants at positions 387-402 is used to demonstrate that transmembrane domain XII is in an alpha-helical conformation.
Homolytic Substitution and Carbenoidic Reactions in the Preparation of Benzimidazole Derivatives of Pharmaceutical Interest: Synthesis and Properties of (2‐Cycloalkyl‐1‐benzimidazolyl)‐<i>N,N</i>‐diethylacetamides (1985)

Abstract The preparation and preliminary biological evaluation of the (2‐cycloalkyl‐1‐benzimidazolyl)‐N,N‐diethylacetamides 7a–e are described. Key steps for the preparation of the compounds 7a–d are (i) the homolytic cycloalkylation of benzimidazole, in which the silver‐catalyzed oxidative decarboxylation of the cycloalkanecarboxylic acids 1a–d by peroxydisulfate is used as a source of alkyl radicals, and (ii) the N ‐alkylation of benzimidazole by the ethoxycarbonylcarbenoid generated by the copper bronze‐catalyzed decomposition of ethyl diazoacetate.
Land and politics in Buganda, 1875-1955 (1964)

Myoclonic jerks involving the proximal limb musculature and tic-like movements (sniffing, coughing, or sighing) were observed in an 11-year-old boy with benign occipital epilepsy treated with carbamazepine (CBZ). The involuntary movements disappeared a few days after withdrawal of CBZ and reappeared with CBZ reintroduction. Plasma CBZ levels were always within the therapeutic range. Polygraphic studies failed to show any electroencephalogram (EEG) changes during myoclonic jerks. Appearance of nonepileptic myoclonus in epileptic children treated with CBZ should be carefully evaluated to prevent worsening of the clinical picture. The coexistence of other involuntary movements (tics) could suggest the correct diagnosis.
A novel fusogenic herpes simplex virus for oncolytic virotherapy of squamous cell carcinoma (2011)

These results indicate that novel oncolytic HSV-1 vectors can be produced with the genetic background of the oncolytic HSV-1 HF, and that RH2 is deficient in γ₁34.5 genes and shows extensive cytopathic effects in oral SCC cells. RH2 may be useful in oncolytic virotherapy for oral SCC.
New Polyalkynyl Dendrons and Dendrimers: “Click” Chemistry with Azidomethylferrocene and Specific Anion and Cation Electrochemical Sensing Properties of the 1,2,3‐Triazole‐Containing Dendrimers (2009)

The synthesis and use of the new tris-alkynyl dendrons 2 to 5 are reported, including the Williamson reaction of 5 with 9-iodo (9), 27-iodo (11), and 81-iodo (12) dendritic cores to yield 27-alkynyl (13), 81-alkynyl (14), and 243-alkynyl (15) dendrimers. So-called "click" reactions of these three dendrimers with azidomethylferrocene (20) give 27-ferrocenyl (16), 81-ferrocenyl (17), and 243-ferrocenyl (18) dendrimers. Electrochemical recognition of oxo-anions (H(2)PO(4)(-) and ATP(2-)) and Pd(2+) cation has been compared using the three polyferrocenyl dendrimers. Derivatization of Pt electrodes with the dendrimers for recognition becomes more facile with increasing size of the dendrimer. This first "click" dendrimer bearing 243-ferrocenyl groups is the best one in the series to obtain robust, recyclable modified Pt electrodes, whereas previous "click" ferrocenyl dendrimers have not been suitable for this purpose.
Channeling of vacuum ultraviolet radiation down tapered capillaries and prospects for a photoemission spectromicroscopy (1994)

The transmission of linear tapered silica-glass capillaries is calculated both numerically and analytically for photon energies in the vacuum-ultraviolet region (10–200 eV). The channeling factor C (ratio of transmitted to line-of-sight flux) is given to a good approximation by 2γ/β, where β is the taper angle and γ is a characteristic decay angle determined entirely by the optical constants. The angular divergence (FWHM) of the output flux is 2.4 (βγ)1/2, and the useful length of the capillary is 2dγβ−3/2, where d is the diameter of the exit aperture. Experimental measurements of photoemission spectra on Au samples using tapered capillaries attached to the end of a conventional resonance lamp confirm these expectations. Channeling factors greater than 103 should be achievable with submicron values of d.
Shear viscosity measurements on Polyamide‐12 polymers for laser sintering (2013)

Purpose Laser sintering kinetics and part reliability are critically dependent on the melt viscosity of materials, including polyamide 12 (PA‐12). The purpose of this paper is to characterise the viscosity of PA‐12 powders using alternative scientific methods: constrained boundary flows (capillary rheometry) and rotational rheometry. Design/methodology/approach Various PA‐12 powders were selected and characterised by both techniques. Measurement of molecular weight was also carried out to interpret the viscosity data. Findings Results demonstrate conventional pseudoplastic flow in all PA‐12 materials. Zero‐shear viscosity has been quantified by rotational rheometry; a notable observation is the striking difference between virgin/used PA‐12. This is interpreted in terms of molecular weight and chain structure modifications, arising from polycondensation of PA‐12 held at the bed temperature during laser sintering. Research limitations/implications Accurate zero‐shear viscosity data provide scope for use in predictive computational models for laser sintering processes. Careful sample preparation and equipment operation are critical prerequisites for accurate rheological characterisation of PA‐12 powders. Practical implications Differences in flow behaviour and molecular structure allow prediction and deeper understanding of process‐property relationships in laser sintering, giving potential for further optimisation of material specification and in‐process machine parameter control. Originality/value This is believed to be the first time that techniques other than melt flow rate (MFR) have been reported to measure the viscosity of PA‐12 in a laser sintering context, noting the effects of pre‐drying and molecular weight, then predicting differences between virgin/used powders in practical sintering behaviour.
Field Aided Lateral Crystallization of Amorphous Silicon Thin Film (1999)

We propose a noble crystallization method of amorphous silicon thin film in this study. Directional crystallization of amorphous silicon thin film was successfully achieved by applying a DC field during heat treatment. The crystallization temperature was lowered to 500°C by employing a trace amount of Ni. The lateral crystallization velocity was 21 µm/h when 53.5 V/cm electric field was applied at 500°C. It also showed the dependence on the applied field intensity. The directionality of the resulting crystallization depended on the polarity of the electric field. This noble technology can be applied to the fabrication of low temperature poly-Si thin film transistors on glass substrates.
5-Hydroxytryptamine 2A receptor antagonists as potential treatment for psychiatric disorders (2013)

Introduction: 5-Hydroxytryptamine 2A receptors (5-HT2A-Rs) are widely expressed in the brain and have been implicated in mood and behavior. Based on the use of atypical antipsychotics in schizophrenia, antagonism of 5-HT2A-Rs initially emerged as a potential intervention capable of reducing the incidence of extrapyramidal symptoms, while exerting an effective antipsychotic action. More recently, highly selective 5-HT2A-R antagonists have been evaluated in the treatment of a wide range of other psychiatric disorders. Areas covered: The aim of the current review is to present important clinical studies investigating the potential therapeutic effects of 5-HT2A-R antagonists in both primary psychiatric disorders, such as schizophrenia and mood disorders, as well as in psychiatric manifestations of neurodegenerative disorders. We present an overview of 5-HT2A-Rs in normal brain function and the rationale for use in (neuro) psychiatric disease based on significant findings from genetic association studies, neuroimaging data and postmortem studies. The majority of the studies relate to schizophrenia, depression, anxiety, obsessive compulsive disorder and psychosis in Parkinson's disease and Alzheimer's disease. To date, there is sparse literature on 5-HT2A-Rs in Gilles de la Tourette syndrome, attention deficit hyperactivity disorder, eating disorders and autism spectrum disorders. The authors conclude by reviewing recent clinical trials investigating highly selective 5-HT2A-R antagonists in schizophrenia, psychosis in Parkinson's disease, insomnia and generalized anxiety. Expert opinion: Despite the potential, to date, 5-HT2A-R antagonists have not made an impact in the management of psychiatric disorders and psychiatric symptoms of neurodegenerative conditions.
