Network monitoring in LTE small cell environment (2015)

In Small cell environment, network monitoring is required so that Home eNB (evolved node base-station) can perform self operations to configure itself, maintain the services by organizing itself and in case of any failure can heal itself. NMM (Network Monitor Mode) is a part of physical layer that does the sniffing of neighbor cells and helps in the monitoring of the network. It can be accessed through FAPI (Femto Application Platform Interface). This paper addresses the technological challenges in validation of neighbor cell sniffing. Network can have single to multi cell environment. Typically, small cell network consists of multiple cells to fulfill the high data rate requirements. During sniffing, NMM module has different set of challenges when there is a single or multiple neighbor cells. In a dense network, environment changes frequently and it becomes difficult for Home eNB to maintain list of neighbor PCID (Physical cell Identifier). In that case, exhaustive sniffing is done which is performed using blind decoding to sniff all of the neighbor eNB. When Home eNB is aware of network environment, it does directed sniffing. There are different procedures from upper layers to enable NMM module for different strategic implementations. This paper covers all of these procedures along with validation details. The scope of this paper is PHY implementation and validation of NMM that cover all functional groups which includes RSSI, RSRP, Sync (Synchronization Information), PBCH (MIB) and BCCH (All SIBs) decoding. This paper will cover NMM procedures, Call Flows, real time field deployment use-case, validation setup, validation-processes etc. Additionally, this will also discuss validation steps, debug tools and functional results. This paper will be an attempt to define and quantify different parameters to adopt technology for network monitoring.
Rheologic determinant changes of erythrocytes in Binswanger's disease. (1999)

Changes in erythrocyte membrane parameters, especially in phospholipids, can produce serious metabolic disorders and influence the rheologic properties of erythrocytes in patients with BD. These alterations can contribute to a circulatory slowdown and may lead to worsening of the condition of the cerebral white matter in these patients.
One chip demodulator using RF front-end SAW correlator for 2.4 GHz asynchronous spread spectrum modem (2002)

A new compact 2.4 GHz spread spectrum (SS) modem has been implemented using a surface acoustic wave (SAW) correlator. The authors have designed and fabricated the 2.4 GHz SAW correlator on AlN/Al/sub 2/O/sub 3/ combination. Using the SAW correlator and SAW delay line at the RF front-end, the 2.4 GHz SS signal is directly demodulated to baseband data. The PN code used is the 11-chip Barker code whose rate is 22 MHz, and baseband data rate is 2 Mbps. The degradation of the measured BER from the theoretical limit is found to be less than 3 dB of E/sub b//N/sub 0/. The authors propose a time division multiplex scheme utilizing the orthogonality of the spreading PN code in the time domain. The channel multiplex is experimentally confirmed using shifted Barker codes.
A coupled OD electrochemical ageing &amp; electro-thermal Li-ion modeling approach for HEV/PHEV (2011)

The technical and commercial success of hybrid-electric vehicles (HEV) and plug-in hybrid-electric vehicles (PHEV) is strongly related to the security, cost and lifetime of the traction battery. Energy and power performances of Li-ion systems are impacted during ageing with a reduction of capacity and an increase of internal impedance. Ageing phenomena occurring in Li-ion batteries are the consequences of combined effect of cycling current, temperature and state-of-charge (SOC). Temperature is one of the most important factors conditioning power performances and ageing of the battery systems. Thermal effects occurring inside cylindrical cells have to be considered in OD battery models for security issues and cycle life optimization through minimization of ageing mechanisms. Most of Li-ion ageing mechanisms have been experimentally identified and described in literature. Ageing models developed in literature generally consider the classical Solid Electrolyte Interphase (SEI)s growth mechanism occurring at the negative carbonaceous electrode. On the one hand, high order pseudo-ID electrochemical models are predictive and reproduce in a good way the evolutions of capacity and power loss during ageing. On the other hand, OD semi-empirical ageing models require lots of experimental data for calibration and are most of the time not predictive with respect to various operating conditions during cycle life of the battery systems. It is then clear that advances in modeling are required to account for physics-based ageing kinetics in zero-dimensional electro-thermal models. In this work, an original OD single electrode electrochemical model taking into account the ageing mechanism of negative electrode surface layer growth via electrolyte diffusion is developed and coupled with a OD impedance-based electro-thermal model. Physics-based first correlations between capacity decrease and impedance increase is proposed. Calibration and validation of the full OD coupled model are performed on experimental data for a commercial cylindrical LiFePO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</inf> /Carbone 2.3 Ah cell. The ageing model is then used to discuss impact of temperature and State-Of-Charge on PHEV duty cycles.
Structure and Dynamics of Polyelectrolyte Complex Coacervates Studied by Scattering of Neutrons, X-rays, and Light (2013)

We investigate the microscopic structure and density fluctuations of complex coacervates of flexible polyelectrolytes using scattering of neutrons, X-rays, and light. Poly(acrylic acid) and poly(N,N-dimethylaminoethyl methacrylate) offer a well-defined model system that allows for selective labeling and systematic variation of the strength of the attractive electrostatic interactions. Two neutron scattering experiments have been carried out: (i) we use deuterated polymeric tracers in a complex coacervate with an overall neutron scattering length density that is matched to that of the solvent, to probe the conformation of single polymer chains in the complex coacervates, and (ii) we measure complex coacervates in which all polymer chains of one type are deuterated, to probe their overall structure. The single chain static structure factors reveal that both polycations and polyanions have an ideal Gaussian chain conformation in the complex coacervates. At the same time, the overall structure is similar to that of a semidilute polymer solution, with polycations and polyanions strongly overlapping to form a network with a mesh size that is much smaller than the radius of gyration of the polymers. The mesh size decreases with decreasing salt concentration, following a scaling that is in good agreement with predictions from the corresponding salt–polymer phase diagram. These findings are confirmed by complementary X-ray scattering experiments. Finally, in all scattering experiments with light, X-rays, and neutrons, and for all polymer chain lengths and salt concentrations, we find a remarkable low-q excess scattering, following a power law with a slope close to -2. This points to the presence of equilibrium, large-scale density fluctuations in the complex coacervates. Dynamic light scattering experiments reveal two complementary diffusive modes in the complex coacervates, corresponding to fluctuations of the polymer mesh and diffusion of domains of varying density, respectively
Antibody CR1-2B11 recognizes a non-polymorphic epitope of human CR1 (CD35) (2007)

Measurement of erythrocyte [red blood cells (RBC)] complement receptor type 1 (CR1, CD35) has the potential to serve as a sensitive assessment of complement activation and immune complex clearance. All previously reported monoclonal antibodies (MoAb) to the extracellular region of CR1 recognize epitopes within the long homologous repeats (LHR) of CR1 and the epitopes for the most frequently used MoAbs are repeated at least twice per CR1 molecule. Furthermore, CR1 exhibits structural polymorphism characterized by a variable number of LHR per molecule. Thus, accurate enumeration of cell surface CR1 using currently available MoAb would require that the results be corrected for the number of antibody epitopes per CR1 molecule encoded by each individual's alleles. To obtain a MoAb to a non-polymorphic epitope on human CR1, hybridomas were generated from mice immunized with recombinant soluble CR1 (sCR1) and MoAb were screened for those that recognized the full-length extracellular domain but failed to bind to all four recombinant LHR fragments. A single antibody, CR1-2B11, was identified and was found to recognize an epitope located wholly within SCR29-30 of CR1, NH2-terminal to an elastase cleavage site. Like other CR1 MoAb, the CR1-2B11 epitope expression decreased on old erythrocytes compared to younger cells and CR1-2B11 did not identify a CR1 'stump' on RBC. Importantly, CR1-2B11 immunofluorescence did not change with storage or handling of RBC, unlike the apparent decrease in immunofluorescence observed with other MoAb. CR1-2B11 should be useful for the accurate enumeration of RBC CR1.

Performance Evaluation of Multiplexing Schemes for IP Packets in Digita Multimedia Broadcasting Systems (2010)

Broadcasting systems with a transport mechanism for IP packets enable enriched multimedia services when used in conjunction with telecommunication services. We have proposed a multiplexing scheme named “TLV” for the efficient transport of IP packets on advanced satellite broadcasting system. We have also proposed a transport mechanism for IP packets on ISDB-TSB, which is a terrestrial multimedia broadcasting system for mobile reception. The transmission characteristics of these transport mechanisms for IP packets need to be examined prior to developing IP-based broadcasting applications. This paper describes our experiments on the transmission systems of the advanced satellite broadcasting system and ISDB-TSB to show the efficient transmission rate and effective delay variation. The results demonstrate that, on the advanced satellite broadcasting system, more than 99% of the transmission capacity is available for applications and the transmission delay variation is quite small. On ISDB-TSB, approximately 80\% of the transmission capacity is available and the delay variation is also small.
Remote booting in a hostile world: to whom am I speaking? [Computer security (1995)

Today's networked computer systems are very vulnerable to attack: terminal software, like that used by the X Window System, is frequently passed across a network, and a trojan horse can easily be inserted while it is in transit. Many other software products, including operating systems, load parts of themselves from a server across a network. Although users may be confident that their workstation is physically secure, some part of the network to which they are attached almost certainly is not secure. Most proposals that recommend cryptographic means to protect remotely loaded software also eliminate the advantages of remote loading-for example, ease of reconfiguration, upgrade distribution, and maintenance. For this reason, they have largely been abandoned before finding their way into commercial products. The article shows that, contrary to intuition, it is no more difficult to protect a workstation that loads its software across an insecure network than to protect a stand-alone workstation. In contrast to prevailing practice, the authors make essential use of a collision-rich hash function to ensure that an exhaustive off-line search by the opponent will produce not one, but many candidate pass words. This strategy forces the opponent into an open, on-line guessing attack and offers the user a defensive strategy unavailable in the case of an off-line attack.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
High-level CAD melds micromachined devices with foundries (1992)

The use of the Magic technology file to build transducer devices in the form of micro-heaters for use as IR pixels in a thermal display is described. Magic is a high-level computer-aided design (CAD) software system. The design methodology incorporated into the current MOSIS SCMOS technology file for Magic to implement the fabrication of silicon micromachined device structures is presented. This technology file uses only the layers supplied by a commercial standard CMOS process. The main advantages of this technique is that no major equipment is needed and the post-processing is reduced to a single, maskless etch step. The main disadvantage is that custom layers can not be incorporated into the design; therefore, the sensors/transducers can only be composed of polysilicon and/or aluminum sandwiched with thermal oxide and CVD oxide.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A protein methylesterase involved in bacterial sensing. (1978)

A protein methylesterase has been identified in soluble extracts of Salmonella typhimurium and Escherichia coli. This enzyme catalyzes the hydrolysis of gamma-glutamyl methyl ester residues from membrane-bound 60,000-molecular weight proteins that are essential for chemotaxis. Analyses of methylesterase activity in a variety of chemotactically defective strains suggest that the methylesterase is a product of the cheX gene in Salmonella and the cheB gene in E. coli. In addition, the cheT gene product in S. typhimurium seems to play a role in expression of methylesterase activity. Mutant strains lacking the protein methylesterase tumble incessantly in the absence of attractant gradients. This behavior is the converse of that shown by mutant strains defective in methyltransferase activity, which swim smoothly in the absence of repellent gradients. This finding indicates that reversible methylation acts as a control mechanism and that both a methyltransferase and a protein methylesterase are instrumental in bacterial sensing.
High-power soliton generation at microwave frequencies (1988)

We point out that the creation of a soliton pulse train in a nonlinear-dispersive system can be used for the generation of high-power microwave bursts. A modulated transmission line with an appropriate nonlinear dielectric is proposed. The nonlinear wave evolution is analyzed and requirements for the dielectric material are found. Problems associated with the material are discussed. Low-power experimental demonstrations of these concepts are presented.

The oxygen electrode. Part 6.—Oxygen evolution and corrosion at iridium anodes (1976)

A comparison of the anodic behaviour of iridium and platinum using both current and corrosion-rate measurements at various potentials showed that the rate of oxygen evolution was considerably faster on iridium in both acidic and basic media. Under constant potential conditions a continuous decrease in current with time was observed in the case of platinum, under all conditions, and in the case of iridium, in base. It is assumed that this effect is due to continuous slow oxidation of the metal substrate with consequent inhibition of electron transfer or of radical reaction at the electrode surface. A sharp break on the Tafel plot for iridium in acidic solution was observed at 1.57 V and was attributed to a change in the rate-determining step, the reaction occurring via hydroxyl radical intermediates both above and below the break. A large increase in current was also observed on this plot at 1.8 V and was attributed to a further change in mechanism, the evolution reaction at higher potentials involving a cyclic change in the oxidation state of iridium ions in the oxide film. The latter change was accompanied by the onset of slow corrosion of the electrode—again suggesting a change in the nature of the anodic film. The corrosion current contributed only a very small fraction of the overall current and gave a linear Tafel plot, the slope of which was twice that of the corresponding plot for total current over the same region of potential. It is postulated that the corrosion reaction and the oxygen evolution reaction in this region involve a common intermediate.
Improvement of low‐temperature caseinolytic activity of a thermophilic subtilase by directed evolution and site‐directed mutagenesis (2009)

By directed evolution and subsequent site-directed mutagenesis, cold-adapted variants of WF146 protease, a thermophilic subtilase, have been successfully engineered. A four-amino acid substitution variant RTN29 displayed a sixfold increase in caseinolytic activity in the temperature range of 15-25 degrees C, a down-shift of optimum temperature by approximately 15 degrees C, as well as a decrease in thermostability, indicating it follows the general principle of trade-off between activity and stability. Nevertheless, to some extent RTN29 remained its thermophilic nature, and no loss of activity was observed after heat-treatment at 60 degrees C for 2 h. Notably, RTN29 exhibited a lower hydrolytic activity toward suc-AAPF-pNA, due to an increase in K(m) and a decrease in k(cat), in contrast to other artificially cold-adapted subtilases with increased low-temperature activity toward small synthetic substrates. All mutations (S100P, G108S, D114G, M137T, T153A, and S246N) identified in the cold-adapted variants occurred within or near the substrate-binding region. None of these mutations, however, match the corresponding sites in naturally psychrophilic and other artificially cold-adapted subtilases, implying there are multiple routes to cold adaptation. Homology modeling and structural analysis demonstrated that these mutations led to an increase in mobility of substrate-binding region and a modulation of substrate specificity, which seemed to account for the improvement of the enzyme's catalytic activity toward macromolecular substrates at lower temperatures. Our study may provide valuable information needed to develop enzymes coupling high stability and high low-temperature activity, which are highly desired for industrial use.
Measuring population health risks using inpatient diagnoses and outpatient pharmacy data. (2001)

Comprehensive pharmacy and inpatient diagnosis classification systems are each helpful for discriminating among people according to their expected costs. Properly organized and in combination these data are promising predictors of future costs.
Acute lung injury following an esophagectomy for esophageal cancer, with special reference to the clinical factors and cytokine levels of peripheral blood and pleural drainage fluid (2007)

Acute lung injury (ALI) is one of most serious complications to occur after an esophagectomy for esophageal cancer. However, the pathogenesis of ALI is still unclear. The cytokine levels of pleural drainage fluid as well as peripheral blood were measured in 27 patients who had undergone an extended radical esophagectomy. Both the clinical factors and cytokine levels were compared between 11 patients with (group I) and 16 without ALI (group II). ALI occurred more frequently in patients who underwent colon interposition than in those who received a gastric tube reconstruction (86%vs 25%, P = 0.009). The operation time of group I was significantly longer than that of group II. A logistic regression analysis revealed colon interposition to be an independent factor associated with the ALI (P < 0.05). Postoperative anastomotic leakage and systemic inflammatory response syndrome (SIRS) occurred more frequently in group I than in group II (P < 0.01). Both the serum interleukin-6 (IL-6) and IL-8 levels of group I were significantly higher than those of group II. IL-1beta and tumor necrosis factor-alpha were undetectable in the peripheral blood, whereas they were detectable in the pleural effusion. The IL-1beta of pleural effusion was higher in group I than group II. In conclusion, greater surgical stress, such as a longer operative time, is thus considered to be associated with the first attack of ALI. The adverse events developing in the extra-thoracic site, such as necrosis and local infection around anastomosis may therefore be the second attack. Furthermore, ALI may cause not only SIRS but also other complications such as anastomotic leakage.

Quorum sensing and the LysR‐type transcriptional activator ToxR regulate toxoflavin biosynthesis and transport in <i>Burkholderia glumae</i> (2004)

Burkholderia glumae BGR1 produces a broad-host range phytotoxin, called toxoflavin, which is a key pathogenicity factor in rice grain rot and wilt in many field crops. Our molecular and genetic analyses of toxoflavin-deficient mutants demonstrated that gene clusters for toxoflavin production consist of four transcriptional units. The toxoflavin biosynthesis genes were composed of five genes, toxA to toxE, as Suzuki et al. (2004) reported previously. Genes toxF to toxI, which are responsible for toxoflavin transport, were polycistronic and similar to the genes for resistance-nodulation-division (RND) efflux systems. Using Tn3-gusA reporter fusions, we found that ToxR, a LysR-type regulator, regulates both the toxABCDE and toxFGHI operons in the presence of toxoflavin as a coinducer. In addition, the expression of both operons required a transcriptional activator, ToxJ, whose expression is regulated by quorum sensing. TofI, a LuxI homologue, was responsible for the biosynthesis of both N-hexanoyl homoserine lactone and N-octanoyl homoserine lactone (C8-HSL). C8-HSL and its cognate receptor TofR, a LuxR homologue, activated toxJ expression. This is the first report that quorum sensing is involved in pathogenicity by the regulation of phytotoxin biosynthesis and its transport in plant pathogenic bacteria.
Deep Learning Aided System Design Method for Intelligent Reimbursement Robot (2019)

Recently, the massive use of invoices has increased the burden on financial staff. In order to ensure high accuracy, conventional financial reimbursement is mainly manual, which wastes lots of human and material resources. This paper proposes an intelligent reimbursement system based on a deep learning method. The system mainly contains face recognition, invoice identification, and information storage. Face recognition ensures the security in the invoice reimbursement, and invoice identification has acceptable accuracy and operating speed. The experimental results indicate that the proposed system achieves both high accuracy and fast running speed.
