Network intrusion detection for cyber security on neuromorphic computing system (2017)

In the paper, we demonstrate a neuromorphic cognitive computing approach for Network Intrusion Detection System (IDS) for cyber security using Deep Learning (DL). The algorithmic power of DL has been merged with fast and extremely power efficient neuromorphic processors for cyber security. In this implementation, the data has been numerical encoded to train with un-supervised deep learning techniques called Auto Encoder (AE) in the training phase. The generated weights of AE are used as initial weights for the supervised training phase using neural networks. The final weights are converted to discrete values using Discrete Vector Factorization (DVF) for generating crossbar weight, synaptic weights, and thresholds for neurons. Finally, the generated crossbar weights, synaptic weights, threshold, and leak values are mapped to crossbars and neurons. In the testing phase, the encoded test samples are converted to spiking form by using hybrid encoding technique. The model has been deployed and tested on the IBM Neurosynaptic Core Simulator (NSCS) and on actual IBM TrueNorth neurosynaptic chip. The experimental results show around 90.12% accuracy for network intrusion detection for cyber security on the physical neuromorphic chip. Furthermore, we have investigated the proposed system not only for detection of malicious packets but also for classifying specific types of attacks and achieved 81.31% recognition accuracy. The neuromorphic implementation provides incredible detection and classification accuracy for network intrusion detection with extremely low power.

Failure of c-myc gene expression in B cells of some patients with common variable immunodeficiencies. (1992)

Many reports have shown that expression of the c-myc protooncogene represents an early event of lymphocyte activation. Calcium influx and activation of protein kinase C synergistically bypass the early signal transduction of lymphocyte activation. In this study, the c-myc message of B cells or B cell lines stimulated by 12-o-tetradecanoylphorbol-13-acetate (TPA), A23187, Staphylococcus aureus Cowan I (SAC), or anti-mu was not expressed or was poorly expressed in common variable immunodeficiency (CVID) patients whose B cells did not differentiate or only poorly differentiated to SAC plus recombinant interleukin 2, whereas the c-myc message of 1 CVID patient's B cells that differentiated well in IgM secretion to SAC plus recombinant interleukin 2 was well expressed when stimulated by TPA, A23187, SAC, or anti-mu. These results suggest that an abnormality exists in the early signal transduction process on some CVID patients' B cells and that it may be in the bypass by calcium influx and direct activation of protein kinase C.
Beyond the Cosmic Veil: Star and Planet Formation Research After SIRTF and NGST (2003)

How do planets form from circumstellar disks of gas and dust? What physical processes are responsible for determining the final masses of forming stars and ultimately the initial mass function (IMF)? The Hubble Space Telescope has made major contributions in helping to address these fundamental questions. In the next decade, the Space Infrared Telescope Facility (SIRTF) and the Next Generation Space Telescope (NGST) will build on this heritage in the near- to far-infrared. However several crucial questions will remain. We review recent progress made in star and planet formation with HST, summarize key science objectives for SIRTF and NGST, and suggest problems that would be uniquely suited to a large aperture UV/optical space-based telescope. We focus on studies that take advantage of high spatial resolution and the unique wavelength range not accessible from the ground such as: 1) circumstellar disk structure and composition (resolved images of dust and UV spectroscopy of gas); and 2) extreme populations of young stars in the local group (UV imaging and spectroscopy of massive star-forming regions). An 8m UV/O space telescope operating from 1100-6000 Angstroms over fields of view 4-10' and with spectroscopic capabilities from R = 3,000-10,000 down to &lt; 1000 Angstroms would be a powerful tool for star and planet formation research.
On the tradeoff between playback delay and buffer space in streaming (2009)

We consider the following basic question: a source node wishes to stream an ordered sequence of packets to a collection of receivers, which are distributed among a number of clusters. A node may send a packet to another node in its own cluster in one time step, whereas sending a packet to a node in a different cluster takes longer than one time step. Each cluster has two special nodes. We assume that the source and the special nodes in each cluster have a higher capacity and thus can send multiple packets at each step, while all other nodes can both send and receive a packet at each step. We construct two (intra-cluster) data communication schemes, one based on multi-trees (using a collection of interior-disjoint trees) and the other based on hypercubes. We use these approaches to explore the resulting playback delay, buffer space, and communication requirements.
Power harvesting for smart sensor networks in monitoring water distribution system (2011)

Recently, there has been a growing interest in using wireless sensor networks for monitoring water distribution infrastructure to help drinking water utilities to have better understanding of hydraulic and water quality statement of their underground assets. One of the challenges is limited power resources for operating the smart sensors and sensor networks. Current common used power supplies for sensor node are batteries. Batteries have many drawbacks such as short life time and need to be replaced on regular basis which is uneconomical and unmanageable in hard access environment such as buried underground water pipelines. Energy harvesting of ambient energy in the water pipeline and powering wireless sensor node including sensing, processing, and communications would be particularly attractive option because the life time of the node will be potentially infinite for supporting wireless sensor networks. The paper will review and discuss the potential of using power harvesting techniques for monitoring water distribution networks and the work done in the area of monitoring water distribution systems using smart sensor networks.
Gene for the RNA polymerase sigma subunit mapped in Salmonella typhimurium and Escherichia coli by cloning and deletion. (1979)

The genes for the RNA polymerase sigma subunit (rpoD) and DNA primase (dnaG) of Salmonella typhimurium have been cloned into lambda vectors. Combined restriction, deletion and functional analysis of the cloned fragment allows us to map the genes precisely on the fragment, establishes the direction in which rpoD is transcribed, and reveals the existence of at least one new gene in the vicinity. A closely homologous, smaller fragment of Escherichia coli DNA, also cloned into lambda, contains rpoD and at least part of dnaG.

Evaluation of H-bridge and half-bridge resonant converters in capacitive-coupled wireless charging (2017)

This paper compares two main topologies used for capacitive-coupled consumer wireless charging which has several advantages over inductive coupling including lower cost and no shielding requirements. There has been minimal data in the literature on preferred transmitter topologies. Two types of transmission systems are compared in simulations and experiments. An experimental charging system was built and tested with the evaluation of efficiency of h-bridge and half bridge transmitters. Preliminary experimental results indicate that the h-bridge is both economically and efficiency-wise advantageous over the half bridge in this application. The overall results show that the H-bridge is more efficient even though it has more semiconductor switching devices causing it to have a slightly higher cost. Immediate future work is implementation of closed-loop control for receiver-side voltage regulation.
Late-Life Depressive Symptoms, Religiousness, and Mood in the Last Week of Life (2012)

Aim of the current study is to examine whether previous depressive symptoms modify possible effects of religiousness on mood in the last week of life. After-death interviews with proxy respondents of deceased sample members of the Longitudinal Aging Study Amsterdam provided information on depressed mood in the last week of life, as well as on the presence of a sense of peace with the approaching end of life. Other characteristics were derived from interviews with the sample members when still alive. Significant interactions were identified between measures of religiousness and previous depressive symptoms (CES-D scores) in their associations with mood in the last week of life. Among those with previous depressive symptoms, church-membership, church-attendance and salience of religion were associated with a greater likelihood of depressed mood in the last week of life. Among those without previous depressive symptoms, church-attendance and salience of religion were associated with a higher likelihood of a sense of peace. For older adults in the last phase of life, supportive effects of religiousness were more or less expected. Fore those with recent depressive symptoms, however, religiousness might involve a component of existential doubt.
Expression of vascular endothelial growth factor C in human esophageal squamous cell carcinoma (2007)

To examine the expression of vascular endothelial growth factor C (VEGF-C) in human esophageal squamous cell carcinoma (ESCC) and to clarify its role in lymphatic metastasis in ESCC. Esophageal carcinoma EC9706 cells and samples of 49 patients with primary ESCC were investigated by using S-P immunohistochemistry (IHC) , semiquantitative RT-PCR in situ and hybridization (ISH) technology for VEGF-C expression, respectively. VEGF-C positive expressions were found in EC9706 cells through ICH, ISH and RT-PCR, respectively. Positive IHC for VEGF-C was observed in 36 of 49 cases of ESCC. The brown staining granules for VEGF-C were identified in the cytoplasm of carcinoma cells. There was significantly difference between the expression of VEGF-C in the group with lymph node metastasia and the group without lymph node metastasis (l = 4. 7, P<O. 05). Positive ISH for VEGFC was observed in 23 of 49 cases of ESCC. The blue-purple staining granules for VEGF-C were identified in the cytoplasm of carcinoma cells. There was a significant difference between the expression of VEGF-C in lymph node group and group without lymph node metastasis (l = 31. 3, P < 0.01). The expression of VEGF-C protein level was significantly higher in group with lymph node metastasia than in group without lymph node metastasis. Of 49 ESCC, VEGF-C gene expression was observed by RT-PCR in 29 cases. There was a significant difference between the expression of VEGF-C in group with lymph node metastasia and group without lymph ~ode metastasis (l = 23.3, P<O. 01). VEGF-C mRNA expression was significantly higher in group with lymph node metastasia than in group without lymph node metastasis. The expression of VEGF-C mRNA level was not significantly associated with age, gender, or pathological grade. There was a correlation between VEGF-C mRNA expressions by RT-PCR and ISH (l = 18.5, P < 0.01) in ESCC, but no significant difference between the two methods. VEGF-C expression may induce lymphangiogenesis in human ESCC. There must be a close correlation between VEGF-C expr~ssion and lymph node metastasis. VEGF-C may be serve as a useful prognostic factor in ESCC. [Life Science Journal. 2007;4 (1):24-28J (ISSN: 1097-8135).
Problems of Furniture Outlets in Malatya City (2017)

Management is activities of work, cooperation, and coordination to get aims of an enterprise. There are many variables such as product, customer, government institutions, finance, and workers at management of furniture outlets. For this reason, furniture outlets have to manage products for customers as for that changing market conditions. The enterprises are faced with customers who care how to present the product. This situation is very important at management of outlet. In this research, it has been researched that the problems of 32 furniture outlet managers with work place, product, workers, customers, institutions, and financial institutions were determined by face to face survey method. The results of the survey were analyzed by Statistical Package for the Social Sciences (SPSS). There were not many problems about work place, on the other hand, it was determined that some problems about the delivery of product time, difference at an incoming product, absenteeism of workers, and their attitudes to customers
Raman, resonance Raman, and infrared spectroscopic study of complexes containing copper(I)–tetrathio-molybdate(VI) and -tungstate(VI) anions (1986)

Raman, resonance Raman at ca. 80 K, and infrared spectra of thirteen ions of the type [MS4-(CuL)n]2–(M = Mo or W; L = CN, SPh, SC6H4Me-4, Cl, or Br; n= 1–4) are reported. Totally symmetric ν(Mo–S) and ν(W–S) stretches are easily identified as giving rise to the most intense bands in the Raman and particularly resonance Raman spectra of the complexes. The pattern (i.e. the number of bands, their wavenumbers and relative intensities) observed in the ν(Mo–S) region (415–496 cm–1) is distinctive for the number of CuI ions co-ordinated to [MoS4]2–.
Maintenance and termination of neocortical oscillations by dynamic modulation of intrinsic and synaptic excitability (2005)

Mechanisms underlying seizure cessation remain elusive. The Lennox-Gastaut syndrome, a severe childhood epileptic disorder, is characterized by episodes of seizure with alternating epochs of spike-wave and fast run discharges. In a detailed computational model that incorporates extracellular potassium dynamics, we studied the dynamics of these state transitions between slow and fast oscillations. We show that dynamic modulation of synaptic transmission can cause termination of paroxysmal activity. An activity-dependent shift in the balance between synaptic excitation and inhibition towards more excitation caused seizure termination by favoring the slow oscillatory state, which permits recovery of baseline extracellular potassium concentration. We found that slow synaptic depression and change in chloride reversal potential can have similar effects on the seizure dynamics. Our results indicate a novel role for synaptic dynamics during epileptic neural activity patterns.

Experimental Wound Dressing by Heterologous Collagen: A Morphological-Quantitative Approach (1993)

The use of heterologous collagen in skin repair processes has proved to be an efficacious approach for the reconstitution of injured tissue. A morphological and quantitative evaluation of the reactive and reparative ca pacity of injured tissue treated either with conventional medications or with heterologous collagen (Condress) in the form of sponges was carried out. We have analyzed experimental surgical lesions on an animal model and evalu ated the repair processes of the lesions, including the excision of the cutaneous and subcutaneous tissue. The heterologous collagen sponges provided biologi cal support to obtain healed skin of better quality. Tissue lesions healed more rapidly, thus reducing the risk of recurrence. This experimental study provides morphological and structural data for further investigation.
The TMT Laser Guide Star Facility (2010)

The Laser Guide Star Facility (LGSF) system of the Thirty Meter Telescope (TMT) will generate the artificial laser guide stars required by the TMT Laser Guide Star AO systems. The LGSF will use multiple sodium lasers to generate and project several asterisms from a laser launch telescope located behind the TMT secondary mirror. In particular, the LGSF will generate a 6-guide-star asterism for the TMT Narrow Field Infrared Adaptive Optics System (NFIRAOS). In this paper, we will present the LGSF requirements, system level tradeoffs, expected performance and the current status of the design, which is based upon solid state continuous wave, 589 nm lasers and conventional beam transport optics.
Comparison of coagulation, ozone and ferrate treatment processes for color, COD and toxicity removal from complex textile wastewater (2017)

In this study, the comparative performance of coagulation, ozone, coagulation + ozone + coagulation and potassium ferrate processes to remove chemical oxygen demand (COD), color, and toxicity from a highly polluted textile wastewater were evaluated. Experimental results showed that ferrate alone had no effect on COD, color and toxicity removal. Whereas, in combination with FeSO<sub>4</sub>, it has shown the highest removal efficiency of 96.5%, 83% and 75% for respective parameters at the optimal dose of 40 mgL<sup>-1</sup> + 3 ml FeSO<sub>4</sub> (1 M) in comparison with other processes. A seed germination test using seeds of Spinach (Spinacia oleracea) also indicated that ferrate was more effective in removing toxicity from contaminated textile wastewater. Potassium ferrate also produces less sludge with maximum contaminant removal, thereby making the process more economically feasible. Fourier transform infrared spectroscopy (FTIR) analysis also shows the cleavage of the chromophore group and degradation of textile wastewater during chemical and oxidation treatment processes.
Fibronectin promotes directional persistence in fibroblast migration through interactions with both its cell-binding and heparin-binding domains (2017)

The precise mechanisms through which insoluble, cell-adhesive ligands induce and regulate directional cell migration remain obscure. We recently demonstrated that elevated surface density of physically adsorbed plasma fibronectin (FN) promotes high directional persistence in fibroblast migration. While cell-FN association through integrins α<sub>5</sub>β<sub>1</sub> and α<sub>v</sub>β<sub>3</sub> was necessary, substrates that selectively engaged these integrins did not support the phenotype. We here show that high directional persistence necessitates a combination of the cell-binding and C-terminal heparin-binding domains of FN, but does not require the engagement of syndecan-4 or integrin α<sub>4</sub>β<sub>1</sub>. FN treatment with various fixation agents indicated that associated changes in fibroblast motility were due to biochemical changes, rather than alterations in its physical state. The nature of the coating determined the ability of fibroblasts to assemble endogenous or exogenous FN, while FN fibrillogenesis played a minor, but significant, role in regulating directionality. Interestingly, knockdown of cellular FN abolished cell motility altogether, demonstrating a requirement for intracellular processes in enabling fibroblast migration on FN. Lastly, kinase inhibition experiments revealed that regulation of cell speed and directional persistence are decoupled. Hence, we have identified factors that render full-length FN a promoter of directional migration and discuss the possible, relevant mechanisms.
Schwann cell interactions with polymer films are affected by groove geometry and film hydrophilicity (2014)

We have developed a biodegradable polymer scaffold made of a polycaprolactone/polylactic acid (PCL/PLA) film. Surface properties such as topography and chemistry have a vital influence on cell-material interactions. Surface modifications of PCL/PLA films were performed using topographical cues and UV-ozone treatment to improve Schwann cell organisation and behaviour. Schwann cell attachment, alignment and proliferation were evaluated on the grooved UV-ozone treated and non-treated films. Solvent casting of the polymer solution on patterned silicon substrates resulted in films with different groove shapes: V (V), sloped (SL) and square (SQ) shapes. Pitted films, with no grooves, were prepared as a negative control. The UV-ozone treatment was performed to increase hydrophilicity. The process specifications for UV-ozone treatment were evaluated and 5 min radiation time and 6 cm distance to the UV source were suggested as the optimal practise. When cultured on grooved films, Schwann cells elongated on the V and SL shape grooves without crossing over, and grew in the direction of the grooves. However, there was less elongation with more crossing over on the SQ shape grooves. The maximum cell length (511 μm) was observed on the treated V-grooved films. The cells cultured on pitted UV-ozone treated surfaces showed random arrangements with no increase in length. We have demonstrated that the synergic effects of physical cues combined with UV-ozone treatment have the potential to enhance Schwann cell morphology and alignment.
