Development of Network User Authentication System Using OpenFlow (2013)

Although a university is a public space, only members can use the network of the university. Therefore, when members use the network, it is necessary to authenticate. We are using Single Sign-On authentication by shibboleth authentication in Saga University. On the other hand, the concept of SDN (Software Defined Network) came out. This is a way of thinking that we can control a network by software. "Open Flow" is new implementation to control a network and well known as a standard of SDN recently. In this research, we have developed a flexible network user authentication system by combine shibboleth authentication and OpenFlow-controller which has been programmed.
Exponential synchronization of nonlinear multi-agent systems with time delays and impulsive disturbances (2015)

The problem of cooperative synchronization of nonlinear multi-agent systems with time delays is investigated in this paper. Compared with the existing works about synchronization (or consensus) of multi-agent systems, the method in this paper provides a more general framework by considering nonlinear multi-agent systems with time delays and impulsive disturbances. The model in this paper is sufficiently general to include a class of delayed chaotic systems. Based on the Lyapunov stability theory and algebraic graph theory, sufficient conditions are presented to guarantee the cooperative exponential synchronization for these multi-agent delayed nonlinear systems. These conditions are expressed in terms of linear matrix inequalities, which can easily be checked by existing software tools. It is seen that the Lyapunov functions must be constructed based on the graph topology to prove synchronization. The well-known master–slave (drive-response) synchronization of two chaotic delayed systems is a special case of this paper, and therefore, the results in this paper are also useful for practical applications in secure communication. Simulation results verify the effectiveness of the proposed synchronization control algorithm. Copyright © 2015 John Wiley & Sons, Ltd.
CSMA-based Packet Broadcast in Radio Channels with Hidden Stations (2016)

Carrier Sense Multiple Access (CSMA) MAC protocols are known to suffer from the hidden station (HS) problem. The complete mathematical analysis of CSMA networks with HSs is still an open problem, even for broadcast communication with a simple linear network topology. In this paper we address this challenge by introducing a MAC layer modeling methodology based on time- and space-domain Markov processes. Using this methodology we derive the closed-form solution for the steady-state performance in infinite one-dimensional (1-D) CSMA networks with HSs. The analytical results are validated by simulation and establish that: 1) under the assumption of fixed frame duration, if the conditional channel access probability at each station exceeds a certain threshold, the CSMA system enters the status of "synchronized transmissions", where a large number of adjacent stations transmit in overlap and interfere each other resulting in null system goodput. 2) The maximum system goodput of CSMA broadcast communication increases with increased station density but becomes increasingly sensitive to the conditional channel access probability. In [25] we validate the analytical results gained in this paper by simulation of a multi-lane highway scenario, and provide quantitative guidance for congestion control algorithms in vehicular networks.
New Adaptive Multi-Expansion Frequencies Approach for SP-MORe Techniques With Application to the Well-Conditioned Asymptotic Waveform Evaluation (2017)

Fast frequency sweep using model order reduction (MORe) techniques is one of the most valuable and efficient features in high-frequency simulators. These techniques usually use a single full solution at a given frequency to build a smaller approximation reduced model, which might be insufficient for wideband and ultrawideband simulations of high quality factor RF and microwave devices. Despite the fact that many computationally reliable error estimate methods have been presented, they all share the same starting point, which is to estimate the residual error between fast sweep solutions and not the actual error. In this paper, we introduce a new accurate and computationally reliable error estimate approach based on the lossless network condition for the automation of single-point MORe. When applied with the well-conditioned asymptotic waveform evaluation, the new approach shows very good performances in terms of accuracy and computation time compared with existing multipoint MORe and commercial EM software.

Resumen en español
Etude de la nature de couches barrieres a l'oxygene realisees par plasma froid basse frequence en fonction des conditions d'elaboration (1999)

Afin de reduire la forte permeabilite a l'oxygene de films plastiques tels le polypropylene (pp), des couches barrieres ont ete deposees par plasma froid basse frequence a partir d'un melange gazeux d'hexamethyldisiloxane (hmdso) et d'oxygene (o 2). Le substrat utilise est un film de pp de 0,018 mm d'epaisseur. Pour changer la nature des depots d'une epaisseur d'environ 100 nm, les parametres plasma modifies sont la puissance p d apportee au plasma, le pourcentage d'o 2 dans le melange gazeux (90 et 96%) et la pression gazeuse (40 et 75 mtorr). Un substrat de silicium place sur le film permet de mesurer l'epaisseur deposee et de realiser une analyse physico-chimique par spectroscopie infrarouge a transformee de fourier. La permeabilite a l'o 2, ou plutot le flux d'o 2 traversant les couches ainsi elaborees est teste grace a un dispositif utilisant une chromatographie en phase gazeuse. L'augmentation de p d conduit a une reduction du flux d'o 2 (facteur 33) a 40 mtorr et a une legere croissance a 75 mtorr. La meilleure couche barriere est obtenue a 75 mtorr, 96% d'o 2 et faible puissance, avec une reduction d'un facteur 45. La composition chimique du depot passe d'un type polysiloxane (sio xc yh z) a un type sio x, perdant peu a peu sa phase organique. A 75 mtorr, les couches sont inorganiques des faible puissance. La structure de la couche se modifie elle aussi, les depots se densifient et presentent un fort degre de reticulation. D'apres le principe de solution-diffusion qui regit la permeabilite, la reduction du volume libre atomique associee a une diminution de la mobilite des segments de chaines polymeres sont responsables de ces resultats. La presence d'un pic ir lie a du co 2 piege dans les couches corrobore cela. Enfin, une meme couche deposee sur differents substrats donne des proprietes barrieres differentes. Via une balance a quartz, une etude de l'adsorption de divers gaz a ete conduite sur des depots flash et long, eux-memes elabores sur differents substrats.

Local protons and uncoupling of aerobic and artificial .DELTA.~.mu.H-driven ATP synthesis (1989)

Gramicidin D causes inhibition of ATP synthesis either in the absence or in the presence of depression of delta muH, in low-salt and in high-salt media, respectively, at concentrations 2 orders of magnitude higher in the former with respect to the latter case. When the number of active redox pumps is reduced by increasing the antimycin concentration, the P/O ratio of respiring, gramicidin-treated mitochondria either is slightly increased in low-salt media or is first decreased and then constant in high-salt media. Addition of gramicidin D in low-salt media to mitochondria synthesizing ATP by means of artificially imposed delta muH gradients results in (a) no effect on the K+ efflux ratio +/- ADP (equivalent to the aerobic respiratory control ratio) and (b) no effect on the ATP/K+ ratio (equivalent to the P/O ratio) except at the low gramicidin D concentrations where there is also a slight enhancement of the rate of ATP hydrolysis. During respiration-driven ATP synthesis, addition of valinomycin plus K+ causes depression of delta muH with little inhibition of ATP synthesis while addition of gramicidin D causes inhibition of ATP synthesis with little depression of delta muH. The view is discussed that the gramicidin-accessible protons which uncouple aerobic ATP synthesis in a delta muH-independent manner are of a different class from the gramicidin-inaccessible protons which uncouple diffusion potential driven ATP synthesis in a delta muH-dependent manner. The gramicidin-accessible protons are suggested to be pump associated and to reflect primary events in energy transduction.

SHP-2 tyrosine phosphatase inhibits p73-dependent apoptosis and expression of a subset of p53 target genes induced by EGCG (2007)

Green tea polyphenol, epigallocatechin-3-gallate (EGCG) differentially regulates the cellular growth of cancer cells in a p53-dependent manner through apoptosis and/or cell cycle arrest. In an effort to further elucidate the mechanism of differential growth regulation by EGCG, we have investigated the role of the tyrosine phosphatase, SHP-2. Comparing the responses of mouse embryonic fibroblasts (MEFs), expressing either WT or functionally inactive/truncated SHP-2, we find that inactivation of SHP-2 remarkably sensitizes cells to EGCG-mediated killing. MEFs lacking functional SHP-2 undergo massive apoptosis upon treatment with EGCG. By comparing gene expression profiles, we have identified a set of transcriptional targets of p53 that are differentially modulated in cells undergoing apoptosis. Western blot and real-time PCR analyses of a select group of genes further confirm that the expression is SHP-2-dependent. Similar observations were made in MEFs lacking p53, confirming that the expression of these "p53 target genes" is p53-independent. In addition, EGCG treatment induced the expression of p73 mRNA and protein in both cell types, but not p63. Inactivation of p73 in cells expressing nonfunctional SHP-2 markedly inhibited apoptosis and p53 target gene expression. Although phosphorylation of JNK is differentially regulated by SHP2, it was found to be dispensable for EGCG-induced apoptosis and p53 target gene expression. Our results have identified SHP-2 as a negative regulator of EGCG-induced-apoptosis and have identified a subset of p53 target genes whose expression is paradoxically not mediated by p53 but by one of its family members, p73.
A Bayesian Approach to Policy Recognition and State Representation Learning (2017)

Learning from demonstration (LfD) is the process of building behavioral models of a task from demonstrations provided by an expert. These models can be used, e.g., for system control by generalizing the expert demonstrations to previously unencountered situations. Most LfD methods, however, make strong assumptions about the expert behavior, e.g., they assume the existence of a deterministic optimal ground truth policy or require direct monitoring of the expert's controls, which limits their practical use as part of a general system identification framework. In this work, we consider the LfD problem in a more general setting where we allow for arbitrary stochastic expert policies, without reasoning about the optimality of the demonstrations. Following a Bayesian methodology, we model the full posterior distribution of possible expert controllers that explain the provided demonstration data. Moreover, we show that our methodology can be applied in a nonparametric context to infer the complexity of the state representation used by the expert, and to learn task-appropriate partitionings of the system state space.
The Progressive Political Power of Balkin's "Original Meaning" (2007)

Jack Balkin's Abortion and Original Meaning should be widely read and debated, not only by constitutional theorists but by a broad range of those who care about his subject: how the United States interprets its foundational document. How should those who are part of that interpretive enterprise-from federal judges to the people-go about the process of defining our core constitutional principles and who we are as a nation? And how should that interpretive process apply to one of the most controversial issues of the day, abortion? Constitutional theory, of course, is the subject of an enormous scholarly literature, and others have agreed with Balkin that the Constitution is both binding law that requires fidelity (over preferred policy outcomes) and in its application to changing times. One obvious question for Balkin-and for anyone writing in the area-is what he adds to the existing literature. By standard measures familiar to legal academics, he contributes much: a jurisprudentially strong interpretive theory that emphasizes the centrality of original meaning from what can be described as a progressive perspective. Fidelity to the Framers does not require, as some originalists suggest and some progressives fear, freezing constitutional norms to the narrow original expectations of the Framers. Nor does a living Constitution approach require disregarding the Framers' original meaning. This comment, though, explores a more unorthodox and indirect contribution: the articulation of a progressive interpretive methodology that is not only strong jurisprudentially, but that also offers the potential for relatively broad accessibility and political efficacy, for the Constitution outside the courts and the
Multiplexed DNA detection with DNA tweezers in a one-pot reaction (2019)

One of the great challenges for the development of biosensors is to construct a fast, practical and multiplexed detection platform. One promising approach is utilizing the controllable conformation of DNA nanostructures for such biosensing applications. Here, we present tweezer-like DNA (TW-DNA)assisted multiplexed DNA detection in a one-pot reaction based on fluorescence quenching. The open conformation of the TW-DNA structure can be changed to a closed state by a specific single-stranded DNA target. The fluorophore/quencher pairs decorated on the TW-DNA and the conformation changes were observed by fluorescence quenching. In its initial state, the TW-DNA is maintained in an open state that demonstrates high fluorescence intensity. In the presence of a specific target DNA, the TW-DNA changes to a closed conformation and the emission intensity of the donor is quenched which is directly proportional to the target concentration. Three DNA targets were simultaneously detected using three individually self-assembled TW-DNA that were modified appropriately with fluorophore/quencher pairs for the specific detection of the individual DNA target. The detection range of this assay is at submicromolar concentration of multiple DNA targets with a fast detection time of one minute. Moreover, this biosensor platform provides the significant advantage of being a one-pot reaction for multiplexed DNA detection without any cross-talk, thereby making it a highly applicable assay.

Advanced Signal Sensing Method With Adaptive Threshold Curve Based on Time Frequency Domain Reflectometry Compensating the Signal Attenuation (2020)

Adaptive fault detection method, which is compensating the wave attenuation along the propagation, is proposed in this article. Long cable system installed in the factory need to develop precise fault detection method considering propagation dispersion. Using the derived time delay between the incident and reflected wave which is generated from the fault, fault can be localized. The time-frequency cross correlation (TFCC) is a signal scanning process based on the similarity of the energy spectrum for detecting the reflected signal mixed with the noise. The threshold value in TFCC is a reference constant value for judging whether or not a fault is present. Due to the attenuation and dispersion of signal along the propagation, a new threshold value function considering attenuation and dispersion is needed. We propose the adaptive threshold curve for compensating the signal attenuation. We design the equivalent circuit of target cable (7m length) and optimal reference signal based on the comparative analysis between the results of computer simulation and actual experiments of 7m length cable. Based on the designed equivalent circuit of target cable(7 m length), a long cable system is modeled by simulation and the performance of the proposed method is proved through the simulation under the various noise level environments.

Novel Branched Nod Factor Structure Results from α-(1→3) Fucosyl Transferase Activity:  The Major Lipo-Chitin Oligosaccharides from Mesorhizobium loti Strain NZP2213 Bear an α-(1→3) Fucosyl Substituent on a Nonterminal Backbone Residue (1998)

Mesorhizobium loti has been described as a microsymbiont of plants of the genus Lotus. Lipo-chitin oligosaccharides (LCOs), or Nod factors, produced by several representative M. loti strains all have similar structures. Using fast-atom-bombardment tandem mass spectrometry and NMR spectroscopy, we have now examined the LCOs from the type strain NZP2213 and observed a much greater variety of structures than has been described for the strains of M.loti studied previously. Interestingly, we have identified as the major LCO a structure that bears a fucose residue alpha-1,3-linked to the GlcNAc residue proximal to the nonreducing terminal GlcNAc residue. This is the first time, to our knowledge, that substitution on an internal GlcNAc residue of the LCO backbone has been observed. This novel LCO structure suggests the presence of a novel fucosyltransferase activity in strain NZP2213. Since the presence of this extra structure does not have the effect of broadening the host range, we suggest that the modification of the LCOs with a fucose residue linked to a nonterminal GlcNAc residue might provide protection against degradation by a particular host plant enzyme (e.g., a chitinase) or alternatively represents adaptation to a particular host-specific receptor. The action of the alpha-(1-->3) fucosyltransferase seems to reduce significantly the activity of NodS, the methyltransferase involved in the addition of the N-methyl substituent to the nonreducing terminal GlcNAc residue. An additional novel LCO structure has been identified having only a GlcNAc2 backbone. This is to our knowledge the first description of such a minimal LCO structure.
The microsomal epoxide hydrolase has a single membrane signal anchor sequence which is dispensable for the catalytic activity of this protein (1994)

The microsomal epoxide hydrolase (mEH) catalyses the hydrolysis of reactive epoxides which are formed by the action of cytochromes P-450 from xenobiotics. In addition it has been suggested that mEH might mediate the transport of bile acids. For the mEH it has been shown that it is co-translationally inserted into the endoplasmic reticulum. Here we demonstrate that the N-terminal 20 amino acid residues of this protein serve as its single membrane anchor signal sequence and that the function of this sequence can also be supplied by a cytochrome P-450 (CYP2B1) anchor signal sequence. The evidence supporting this conclusion is as follows: (i) the rat mEH and a CYP2B1-mEH fusion protein, in which the CYP2B1 membrane anchor signal sequence replaced the N-terminal 20 amino acid residues of mEH, was co-translationally inserted into dog pancreas microsomes in a cell-free translation system, whereas a truncated epoxide hydrolase with a deletion of the 20 N-terminal amino acid residues was not co-translationally inserted. (ii) The mEH and the CYP2B1-mEH fusion protein, but not the truncated epoxide hydrolase, were anchored in microsomes in a cell-free translation system and in membrane fractions derived from fibroblasts which expressed these proteins heterologously. These fibroblasts were also used to evaluate the significance of the mEH membrane anchor for the catalytic activity of mEH. The mEH, the truncated mEH and the CYP-EH fusion protein were found to be enzymically active. This result shows that the membrane anchor signal sequence of mEH is dispensable for the catalytic activity of this protein. However, truncated mEH was only expressed at low levels, which might indicate that this protein is unstable.
