Caveolin-1 Mediated Endocytic Pathway is Involved in Encephalomyocarditis Virus Replication in BHK-21 Cells

Background: Encephalomyocarditis virus, member of Cardiovirus genus within Picornaviridae family, is an important pathogen that infects different domestic and wild animals. However, the molecular mechanism of its entry remains unclear. In this study, we investigated the mechanism of EMCV infectivity in relation to endocytic pathway using BHK-21 cells. Methods: The function of numerous cellular key factors implicated in the various endocytic mechanisms were systematically explored using chemical inhibitors. Furthermore, RNA interference (RNAi) as well as the overexpression of dominant protein combined to virus infectivity assays, and confocal microscopy was used to examine EMCV infection in details. Results: The results indicated that the EMCV entry into BHK-21 cells depends on caveolin, dynamin, and actin but not clathrin nor macropinocytosis pathways. The effects of overexpression and knockdown of caveolin-1, one components of the caveolae, was examined on EMCV infection. The results showed that EMCV infection was positive correlation with caveolin-1 expression. Confocal microscopy analysis and internalization assay showed that caveolin-1 is required at the early stage of EMCV infection. Conclusions: Caveolin-1, dynamin, and actin-dependent endocytosis pathways are necessary for EMCV infection in vitro.
Two axis direction finding antenna system using sum–difference patterns in X band

This work proposes the direction finding antenna system in two axis (θ1, θ2) in X band using sum (Σ) and difference (Δ) patterns of received signal. Direction finding system is constructed by implementing the microstrip patch antenna array and 180° hybrid rat race ring coupler which generates Σ and Δ patterns of received RF signal. Initially, direction of arrival (DOA) is obtained in one axis, (θ1), vertical direction, using the Σ–Δ patterns of antenna array of two elements. Using the equations of Σ and Δ of two input signals, radiation patterns at different θ values have been observed in simulation and compared with measured pattern values of constructed circuit. By taking the ratio of Δ to Σ patterns, DOA has been estimated of designed circuit. Another circuit similar to first circuit, oriented at 90° (horizontal direction) has been implemented to estimate the DOA (θ2) in other axis. By taking the 3D radiation patterns of each circuit in anechoic chamber, both circuits are measured for performance; and from 0 to ±40°, DOA has been observed with rms error of less than 5° in both axis. At 10 GHz operating frequency, experimental results, using material RT Duroid 5880, show that satisfactory performance can be achieved with proposed setup. © 2015 Wiley Periodicals, Inc.

Evaluations of SSC Diversity Receiver over EGK Fading Channels

Abstract In this paper, a detailed performance analysis of switch-and-stay combining receivers over non identical distributed extended generalized K fading channels is presented. The analysis has been performed in both noise and interference-limited environments (the level of interference or noise is ignored, respectively). The expressions for the output signal-to-noise (SNR) and signal-to-interference (SIR) probability density function and cumulative distribution function, in a form of Fox's H functions, are presented. Based on this, analytical expressions for evaluating the moments, outage probability, average bit error rate and average channel capacity are derived. The influence of fading and shadowing phenomena, as well as the influence of unbalanced input SNR/SIR on the most important performance metrics is obtained. Presented numerical results are confirmed by Monte Carlo simulations.
An efficient distributed navigation algorithm for mobile robot

An efficient distributed algorithm for mobile nodes of wireless sensor network (WSN) is proposed. A smart mobile robot is designed as the special node of WSN, and the nodes of WSN are deployed in the environment as signposts for the robot to follow. We use the RSSI value between the robot and other static nodes as the input of the navigation control system. The mobile robot state and navigation space are denoted by the RSSI potential field. Navigation directions are computed by using fuzzy logic method. To reduce the communication expense, each node within one hop communication range of robot is a distributed navigation unites. Then the fuzzy logic control centre will collect the control outputs from every beacon nodes and calculate the final outputs for mobile robot based on data fusion. The experimental results confirm that the navigation system based on WSN successfully achieved their assigned tasks.
The characteristics of pressure ripple in variable displacement vane pumps: Comparison between theory and experiment

Abstract This paper reports on the theoretical and experimental study on the discharge pressure ripples in a variable displacement vane pump. The pressure ripple in the delivery port is caused by flow ripple, which is induced by variation of pumping chamber volume. The other reason is the reverse flow from the outlet volume produced by the pressure difference between the pumping chamber and the outlet volume when the pumping chamber is connected to the outlet volume. In this study, a mathematical model is presented for analysing discharge pressure ripple, which includes vane detachment, cam ring movement and fluid inertia effects in a V-groove in the side plate. The model is applied to predict the level and the waveform of the discharge pressure ripples for various operating conditions. An experiment was performed to verify the theoretical analysis. The theoretical results provided in this study show a good agreement with the experimental results. This analytical model can predict the magnitude of discharge pressure ripple in variable displacement vane pumps and thus is useful for achieving optimal design of vane pumps.

Consequently, the main goal of this study is the design of a practical method for aligning strategy development with implementation by using capability-based planning. This method will help organizations with translating their strategy into implementation.
Experimental Evaluation of Torque Performance of Voltage and Current Models using Measured Torque for Induction Motor Drives

In this paper, two kinds of observers are proposed to investigate torque estimation. The first one is based on a voltage model represented with a lowpass filter (LPF); which is normally used as a replacement for a pure integrator to avoid integration drift problem due to dc offset or measurement error. The second estimator used is an extended Kalman filter (EKF) as a current model, which puts into account all noise problems. Both estimation algorithms are investigated during the steady and transient states, tested under light load, and then compared with the measured mechanical torque. In all conditions, it will be shown that the torque estimation error for EKF has remained within narrower error band and yielded minimum torque ripples when compared to LPF estimation. This motivates the use of EKF observer in high performance control drives of induction machines for achieving improved torque response.

Environmental Control Issues in a New Energy-Efficient Building

The availability of adjustable lighting controls, with options other than “on” and “off,” have been associated with increased energy savings. In the present study, we describe the way customizable, networked lighting controls are actually used in a recently built research facility that received a formal designation for sustainable design (LEED Gold). In addition to usage patterns, we explored occupants’ knowledge of control operation as well as the expectancies of nonoccupants. We also identified a variety of features that, if redesigned in accordance with HF/E principles, might lead to reduced lighting usage.
Deficiencies of 'Kronecker' MIMO radio channel model

Evidence that the ‘Kronecker’ model underestimates the channel capacity of an 8×8 multiple input, multiple output (MIMO) system in indoor non-line-of-sight (NLOS) scenarios is presented. Moreover, the model does not render the multipath structure correctly, which is the cause for the systematic capacity mismatch.

Residual strength of panels with multiple site damage

This article describes research aimed at predicting the residual strength (RS) of unstiffened aluminum panels that contain multiple site damage (MSD). The initial damage consists of through-the-t hickness cracks emanating from a row of holes in the center of a 23-cm- (9-in.-) wide panel. The row of holes is aligned perpendicular to a remote tensile load, and three failure criteria are employed to predict the fracture resistance of the cracked panel. RS tests of 2024-T3 aluminum panels with MSD were conducted to evaluate the analyses. The RS tests validate a failure criterion that includes plastic zone considerations for panels with a lead crack spanning the central holes and with small MSD cracks at other holes. The RS tests also demonstrate that significant loss of strength occurs when MSD cracking exists, even when the cracks are relatively small.
Dielectric breakdown characteristics of clean oil

The dielectric strength of highly filtered and dehydrated oil was investigated with AC and impulse voltages. The influence of particles on breakdown strength is discussed, taking into account the particle content factor. The scale effect of superclean oil, which was obtained from a modern cleaning system, is studied from a statistical viewpoint. The experimental result is interpreted using the weakest link theory. With this interpretation, the dependence of breakdown strength on stressed oil and electrode area are discussed. In the case of the impulse voltage, the dielectric strength was influenced by the stressed oil volume. In the case of the AC voltage, the dielectric strength depended on the electrode area effect. <<ETX>>
NUMERICAL AND EXPERIMENTAL INVESTIGATION OF CAVITATING FLOW IN OIL HYDRAULIC BALL VALVE

The three-dimensional cavitating flow issuing from the orifice of a ball valve was numerically investigated using the combination of RNG k-e turbulence model and multiphase flow model. The cavitation region was predicted for axisymmetric and non-axisymmetric case when the ball moves to one side. Flow visualization experiment was conducted to capture cavitation images near the orifice of the ball valve using high-speed video camera. The predicted and observed cavitation regions agree well. Furthermore, the noise spectrums of the ball valve in cavitation and non-cavitation cases were measured. The results show that the cavitation around the orifice occurs periodically with a very high frequency of 2500 Hz. The predicted cavitation region for axisymmetric and non-axisymmetric case was compared with experimentally visualized cavitation image. It was expected that the ball vibrates in the lateral direction and cavitation occurs periodically.
Rapid waveguide system and component design using scattering matrices and computer optimization

Summary form only given. Scattering matrix analysis revolutionized the design of overmoded gyrotron circuits and is now used for designing waveguide components, including pillbox and coaxial windows, mode converters, tapers, and transitions. The addition of computer optimization dramatically reduces design time while significantly increasing performance. Combining computer optimization with scattering matrix analysis allows users to design entire waveguide systems in a few hours with performance exceeding what usually takes days to obtain with other programs. This presentation describes the application of scattering matrix and optimization analysis to waveguide system design and provide several examples.
MEMS analog light processing: an enabling technology for adaptive optical phase control

Various applications in modern optics are demanding for Spatial Light Modulators (SLM) with a true analog light processing capability, e.g. the generation of arbitrary analog phase patterns for an adaptive optical phase control. For that purpose the Fraunhofer IPMS has developed a high-resolution MEMS Micro Mirror Array (MMA) with an integrated active-matrix CMOS address circuitry. The device provides 240 x 200 piston-type mirror elements with 40 μm pixel size, where each of them can be addressed and deflected independently at an 8bit height resolution with a vertical analog deflection range of up to 400 nm suitable for a 2pi phase modulation in the visible. Full user programmability and control is provided by a newly developed comfortable driver software for Windows XP based PCs supporting both a Graphical User Interface (GUI) for stand-alone operation with pre-defined data patterns as well as an open ActiveX programming interface for a direct data feed-through within a closed-loop environment. High-speed data communication is established by an IEEE1394a FireWire interface together with an electronic driving board performing the actual MMA programming and control at a maximum frame rate of up to 500 Hz. Successful application demonstrations have been given in eye aberration correction, coupling efficiency optimization into a monomode fiber, ultra-short laser pulse modulation and diffractive beam shaping. Besides a presentation of the basic device concept the paper will give an overview of the obtained results from these applications.
A Bayesian approach for vibration-based long-term bridge monitoring to consider environmental and operational changes

This study aims to propose a Bayesian approach to consider changes in temperature and vehicle weight as environmental and operational factors for vibration-based long-term bridge health monitoring. The Bayesian approach consists of three steps: step 1 is to identify damage-sensitive features from coefficients of the autoregressive model utilizing bridge accelerations; step 2 is to perform a regression analysis of the damage-sensitive features to consider environmental and operational changes by means of the Bayesian regression; and step 3 is to make a decision on the bridge health condition based on residuals, differences between the observed and predicted damage-sensitive features, utilizing 95% confidence interval and the Bayesian hypothesis testing. Feasibility of the proposed approach is examined utilizing monitoring data on an in-service bridge recorded over a one-year period. Observations through the study demonstrated that the Bayesian regression considering environmental and operational changes led to more accurate results than that without considering environmental and operational changes. The Bayesian hypothesis testing utilizing data from the healthy bridge, the damage probability of the bridge was judged as no damage. Keywords: long-term bridge monitoring; Bayesian regression; temperature; vehicle weight; vibration
Simulation and timing performances of integrated waveguides for ultra‐high speed interconnects

Integrated circuit technology is causing system designs to move toward complex architectures, requiring communication channels characterized by ever increasing capacity. In this context, classical metallic interconnects become a bottleneck, owing to the power consumption, crosstalk, and signal integrity issues. Substrate integrated waveguides (SIW) are a potential technological solution to overcome traditional interconnect limitations. In this article, the authors present frequency and time domain analysis of these structures, comparing two different SIW structures in terms of time and signal dispersion performances. © 2008 Wiley Periodicals, Inc.

A miniature silicon accelerometer with built-in damping

Silicon micromachining was utilized to produce a novel, miniature accelerometer comprising a three-layer silicon structure. The center layer contains the accelerometer proof mass supported by a double cantilever suspension. The outside two silicon caps provide protection, mechanical stops for the proof mass, and air damping of its major resonant frequencies. Critical damping is typically provided. Piezoresistors are used to sense the deflection of the silicon mass. By cross coupling the eight resistors in a Wheatstone bridge, substantial reduction in sensitivity to off-axis acceleration has been achieved. The integral packaging and air damping reduces production costs by simplifying the final assembly steps. <<ETX>>
High-performance InGaAs-on-silicon avalanche photodiodes

We have demonstrated a high-performance InGaAs-on-silicon APD that exhibits a very low dark current density of 0.7 mA/cm/sup 2/, high avalanche gain (M/spl Gt/100), an RC-limited bandwidth of 1.45 GHz, and a gain-bandwidth product of 290 GHz. We estimate that our device can achieve a sensitivity improvement of 5 dB compared to state-of-the-art InP-based APD receivers. We are currently measuring the APD excess noise factor. We will report this measurement at the conference.
A neurofuzzy spatial decision support system for pipe replacement prioritisation

Spatial Decision Support Systems (SDSS) represent an attempt to assist in the decision making process by a set of intelligent, knowledge-based techniques and as such have an increasingly important role to play as the data required for spatially sensitive decisions become more available in a wide range of problem areas. The urban environment is a complex, spatially sensitive decision-making environment and as such an ideal case study for the application of these techniques and tools. Building knowledge into a system, particularly through linguistic modelling, is a challenge. This paper briefly discusses the development of such an SDSS based on fuzzy inference and describes techniques enabling the incorporation of both expert judgement and field evidence, where available, in an effort to address one of the main criticisms of linguistic (fuzzy) modelling: that of subjectivity.

The authors report 1.56 µm MQW BH lasers that use a tapered active region and underlying passive guide to increase the laser spot size. Coupling losses to 10 µm core cleaved singlemode fibre as low as 4.7 dB have been obtained for devices with threshold currents of ~12 mA at 20°C.
Aerodynamics Performance of Endwall Film Cooling under the Influence of Purge Flow in High Pressure Turbine Cascade

Modern gas turbine requires sophisticated cooling technologies to avoid thermal failure due to the extreme operating environment. Film cooling is one of the most important cooling technologies used for gas turbine hot-section components, particularly for blade aerofoil surfaces and endwall. Previous research has shown that the endwall region is considerably more difficult to cool than the blade aerofoil surfaces because of the existence of complex secondary flow structures such as horse-shoe vortex, cross flow and passage vortex in the blade passage. Therefore, this study focuses on aerodynamics interaction of the cooling air through the upstream slot with the secondary flow field. Experiments carried out using 5-holes Pitot tube have revealed the secondary flow field at blade downstream of linear cascade of high pressure turbine. A baseline condition without any leakage flows was compared with the leakage ejection case. Finally, both cases were validated by simulations from commercial software, ANSYS CFX.
