A Simple and Safe Electrostatic Method for Managing Houseflies Emerging from Underground Pupae (2023)

A simple electrostatic apparatus that generates an arc discharge was devised to control adult houseflies emerging from a soil bed in a greenhouse. Adult houseflies emerging from a soil bed in a greenhouse are a potential vector of pathogenic Escherichia coli O157, carried by animal manure used for soil fertilization. A simple electrostatic apparatus that generates an arc discharge was devised to control these houseflies. The apparatus consisted of two identical metal nets; one was linked to a negative-voltage generator to create a negatively charged metal net (NC-MN), and the other was linked to a grounded line to create a grounded metal net (G-MN). A square insulator frame was placed between the two nets, separating them by 6 mm, and a plastic grating with multiple cells was placed beneath the G-MN to provide a climbing path (54 mm in height) to the arcing sites of the apparatus for adult houseflies emerging on the soil surface. Houseflies that climbed up the wall of the grating and reached the arcing zone were subjected to arc-discharge exposure from the NC-MN and thrown down onto the soil by the impact of the arcing. The impact was destructive enough to kill the houseflies. The structure of this apparatus is very safe and simple, enabling ordinary greenhouse workers to fabricate or improve it according to their own requirements. This study developed a simple and safe tool that provides a physical method to manage houseflies.
Optimized partial eigenstructure assignment-based design of a combined PSS and active damping controller for a DFIG (2010)

Summary form only given. The paper applies the method of eigenstructure assignment for the design of a controller for a wind generation scenario in Northern Scotland based on doubly-fed induction generators (DFIGs). The designed controller serves the combined purpose of a conventional power system stabilizer (PSS) and an active damping controller and provides a contribution to both network and shaft damping. This novel approach is superior because all available degrees of freedom are fully exploited by selecting not only the new eigenvalue locations but also certain elements of the left eigenvectors. These elements are obtained by solving a multiobjective nonlinear optimization problem (MONLOP). Examples are presented to demonstrate that optimizing the eigenvectors yields a better performing controller in comparison with one designed using mere eigenvalue relocation.
Backprojection Imaging of Moving Objects (2020)

A backprojection-based synthetic aperture radar (SAR) processing approach for fast and accurate imaging of moving objects and stationary background is proposed. This divide-and-conquer backprojection approach allows for efficient detection of moving objects, estimation of their positions and velocities, and overlaying their focused images over the stationary background. Two algorithms are presented to exploit the tradeoff between the complexity and performance. The full 4-D phase space imaging algorithm provides the optimal performance under low signal-to-clutter conditions, while the adaptive detection and imaging leads to reduced complexity in more favorable scenarios. We show that in a single-channel SAR the conventional straight-line data collection path does not resolve the target's velocity, therefore a curved path is assumed in the formulation and numerical examples.
Improving Third-Party Relaying for LTE-A: A Realistic Simulation Approach (2014)

In this article we propose solutions to diverse conflicts that result from the deployment of the (still immature) relay node (RN) technology in LTE-A networks. These conflicts and their possible solutions have been observed by implementing standard-compliant relay functionalities on the Vienna simulator. As an original experimental approach, we model realistic RN operation, taking into account that transmitters are not active all the time due to half-duplex RN operation. We have rearranged existing elements in the simulator in a manner that emulates RN behavior, rather than implementing a standalone brand-new component for the simulator. We also study analytically some of the issues observed in the interaction between the network and the RNs, to draw conclusions beyond simulation observation. The main observations of this paper are that: $i$) Additional time-varying interference management steps are needed, because the LTE-A standard employs a fixed time division between eNB-RN and RN-UE transmissions (typical relay capacity or throughput research models balance them optimally, which is unrealistic nowadays); $ii$) There is a trade-off between the time-division constraints of relaying and multi-user diversity; the stricter the constraints on relay scheduling are, the less flexibility schedulers have to exploit channel variation; and $iii$) Thee standard contains a variety of parameters for relaying configuration, but not all cases of interest are covered.
Neuroticism Associates with Cerebral in Vivo Serotonin Transporter Binding Differently in Males and Females (2017)

The finding is in agreement with recent studies showing that the serotonergic system is involved in affective disorders differently in males and females and suggests that contribution of thalamic serotonin transporter to the risk of affective disorders depends on sex.
Hepatocellular uptake of oleate is energy dependent, sodium linked, and inhibited by an antibody to a hepatocyte plasma membrane fatty acid binding protein. (1986)

Several studies suggest that a portion of hepatocellular nonesterified fatty acid uptake may be carrier mediated. To further investigate this process, initial rates (Vo) of [14C]oleate uptake into rat hepatocytes, isolated by collagenase perfusion and incubated at 37 degrees C with oleate in the presence of bovine serum albumin, were studied as a function of the concentration of unbound [14C]oleate in the medium. Vo was saturable with increasing unbound oleate concentration (Km = 8.3 X 10(-8) M; Vmax = 197 pmol per min per 5 X 10(4) hepatocytes) and was not inhibited by up to 40 microM sulfobromophthalein, taurocholate, or cholic acid. Oleate uptake was sodium dependent. Vo was significantly diminished when Li+, K+, choline, or sucrose were substituted for Na+ in the incubation medium and was reduced 46% by 1 mM ouabain. Uptake was also markedly reduced after exposure of cells to metabolic inhibitors (e.g., 2,4-dinitrophenol, carbonyl cyanide m-chlorophenylhydrazone, antimycin, KCN). To evaluate the physiologic significance of the previously isolated rat liver plasma membrane fatty acid-binding protein, the effect of an antibody directed against this protein on hepatocellular [14C]oleate uptake was examined. Preincubation of hepatocytes with the IgG fraction of this antiserum inhibited Vo of [14C]oleate by up to 65% in dose-related fashion, without altering Vo for [35S]sulfobromophthalein, [14C]taurocholate, or [3H]cholate. These data indicate that at least a portion of hepatocellular oleate uptake is energy dependent, sodium linked, and mediated by a specific liver plasma membrane-fatty acid-binding protein.

Design and Cryogenic Operation of a Hybrid Quantum-CMOS Circuit (2015)

Tomorrow's electronics will be ``beyond CMOS'', but the transition can and should be smoothed, to take full advantage of what we already know and use well. In proof of principle, the authors combine a Coulomb-blockade device with a standard circuit for generating rf signals. The combination is completely dc tunable, and remarkably works down to a very cold 2 K. Such co-integration of quantum and conventional CMOS circuitry draws upon solid-state device physics, microelectronics engineering, and advanced processing---a truly interdisciplinary achievement.
Contrasting responses of organic transistors to nerve gas and explosive simulant vapors (2009)

We describe chemically sensitive organic transistors in which the semiconductor film consists of a base layer of a high mobility p- or n-channel molecular solid, and an overlayer contains analogous compounds terminated with hydroxy functional groups. Such devices respond to dimethyl methylphosphonate at concentrations on the order of 100 ppb and on time scales &lt;1 minute. Semiconductor cores include diphenylbithiophene and naphthalenetetracarboxylic diimide, with OH end groups in some cases. End groups include both alkyl and phenolic OH. Devices are as thin as four monolayers. Sensitivity is highly gate dependent, and means of ensuring the gate setting for maximum response are proposed. Contrasting response to dinitrotoluene, a component of nitroaromatic explosive vapors, is reported. Finally, the influence of the channel versus near-contact regions on the vapor-induced changes in resistance is evaluated.
Electrical Immunoassays toward Clinical Diagnostics: Identification of Vulnerable Cardiovascular Plaque (2008)

A technology for electrical detection of protein biomarkers has been developed. It is based on developing high-density, low-volume multiwell plate devices. The scientific core of this technology lies in integrating nanoporous membranes with microfabricated chip platforms. This results in the conversion of individual pores into wells of picoliter volume. Specific antibodies are localized and isolated into individual wells. The formation of the antibody–antigen-binding complex occurs in individual wells. The membrane allows for robust separation among individual wells. This technology has the capability to achieve near real-time detection with improved sensitivity and selectivity. This is due to the two factors associated with the technology: (1) event-based electrochemical detection process, where the individual step in the formation of the binding complex results in a specific change to the electrochemical conductance due to the pertubation of the electrical double layer at the base of the each well. (2) The nanoporous membrane is an electrical insulator and is structurally robust throughout hence there is improved signal-to-noise ratio and cross-contamination between is minimized. Another advantage of this technique is the use of electrical signal in protein identification as compared to the use of optical methods; hence, it is a noninvasive and a label-free technique. The signal acquisition is simple and it uses the existing data acquisition and signal analysis methods. We have demonstrated the use of this technology for addressing a specific clinical problem: identification of vulnerable coronary plaque in the perioperative state.
Clinical and Experimental Trials in Cardiology (2020)

Clinical trials are experiments or observations done in clinical research. Such prospective biomedical or behavioral
research studies on human participants are designed to answer specific questions about biomedical or behavioral
interventions, including new treatments (such as novel vaccines, drugs, dietary choices, dietary supplements, and
medical devices) and known interventions that warrant further study and comparison. Clinical trials generate data
on safety and efficacy.
Optimization of parallel processing intensive digital front-end for IEEE 802.11ac receiver (2016)

Modern computing platforms offer increasing levels of parallelism for the fast execution of different signal processing tasks. In this paper a digital front-end concept is developed, where the parallel processing is utilized for dividing the inherent structure of IEEE 802.11ac waveform to two or more parallel signals and by processing the resulting signals further e.g, using legacy IEEE 802.11n digital receiver chains. Two multirate channelization architectures are developed with the corresponding filter coefficient optimization. The full radio link performance simulations with commonly adopted indoor WiFi channel profiles are provided, verifying the overall link performance with the proposed channelization architectures.
High-bright and efficient green light-emitting diode using poly[2-(9`,9`-bishexylfluorenyl)-1,4- phenylenevinylene] (2001)

The poly[2-(9',9'-bishexylfluorenyl)-1,4- phenylenevinylene] (BHF-PPV), which is PPV containing 9,9- bishexylfluorene as a pendant group, was synthesized by the modified Gilch dehydrohalogenation polymerization of the corresponding bischloromethyl-substituted benzene monomer. The energy levels of the highest occupied molecular orbital and the lowest unoccupied molecular orbital of BHF-PPV were 5.35 and 2.94 eV as determined by cyclic voltammetry. Band gap, estimated from both cyclic voltammetry and optical absorption measurement, agrees well to be 2.41 eV. The EL spectrum showed two peaks at 504 and 535 nm, which very closely resembled the PL spectrum of the polymer film, demonstrating that the PL and EL originate from the same excited state. Blue-green LED was fabricated using BHF-PPV as the emissive layer, PEDOT:PSS as the hole-injection layer, and Mg-Ag alloy as the cathode. The device emitted bright blue-green light with turn-on voltage of 3.0 V and exhibited luminance efficiency and power efficiency of 0.64 cd/A and 0.45 lm/W, respectively, at the luminance of 105.1 cd/m<SUP>2</SUP> driven at the voltage of 4.5 V and current density of 16.37 mA/cm<SUP>2</SUP>.
Video Sending Rate Prediction Based on Communication Logging Database for 5G HetNet (2018)

Recently research and development on the 5th generation mobile communication system (5G) is actively carried out to launch commercial service in 2020. In 5G, Super high frequency (SHF) band and extremely high frequency (EHF) band are used for realizing high speed and large capacity communication. Furthermore, 5G network will include many wireless LANs (Local Area Networks) as well as cellular network. Therefore, 5G network is composed as the heterogeneous network (HetNet). In 5G HetNet, a user equipment (UE) connects various base stations (BS) according to its movement. Accordingly, it is assumed that the throughput suddenly fluctuates due to the change of radio links. By the way, 5G is expected as a communication means for large capacity video contents such as 4K/8K video and omnidirectional video. However there is a problem that the conventional video transmission technology cannot effectively utilize the 5G throughput according to an environment. In this paper, we propose a method to predict the video transmission throughput by using the location information and the communication logging information. The logging information including past throughput with the location is created by a UE. A UE refer to the logging information for prediction when the BS which is attached to the UE is changed or the radio quality is declined. We developed a video transceiver implemented the proposed method and evaluated its performance. We show that the proposed method can stably transmit high resolution video compared to the conventional method.
A Note on an Optical Method to Evaluate Fiber Dispersion in Wet-laid Nonwoven Process (2008)

A laboratory set-up using an online vision system was designed to observe the dispersion behavior of glass and polyester fibers. The effect of different blend ratios, agitation speed, and dispersion time in dispersing “logs” and formation of “ropes”, was studied. Our results indicate that there is a specific dispersion time period in which optimum fiber dispersion can be achieved. This time was found to be shorter for glass fibers. It was observed that the dispersion behavior of each fiber type has a profound influence on the dispersion of fiber blends. It was also noted that there is an optimum agitation energy which allows the logs to be dispersed while minimizing the rope formation.

On the Structure and Kinematics of an Algerian Eddy in the Southwestern Mediterranean Sea (2021)

An Algerian Eddy, anticyclonic vortex generated by the instability of the Algerian Current in the southwestern Mediterranean Sea, is studied using data provided by drifters (surface currents), Argo floats (temperature and salinity profiles), environmental satellites (absolute dynamic topography maps and ocean color images) and operational oceanography products. The eddy was generated in May 2018 and lasted as an isolated vortex until November 2018. Its morphology and kinematics are described in June–July 2018 when drifters were trapped in its core. During that period, the eddy was slowly moving to the NE (~2 km/day), with an overall diameter of about 200 km (slowly growing with time) and maximal surface swirl velocity of ~50 cm/s at a radius of ~50 km. Geostrophic currents derived from satellite altimetry data compare well with low-pass filtered drifter velocities, with only a slight overestimation, which is expected as its maximum vorticity corresponds to a small Rossby number of ~0.6. Satellite ocean color images and some drifters show that the eddy has an elliptical spiral structure. The looping tracks of the drifters trapped in the eddy were analyzed using two statistical methods: least-squares ellipse fitting and wavelet ridge analysis, revealing a typical eccentricity of about 0.5, a wide range of inclination and a rotation period between 3 and 10 days. Clusters of drifters on the northeastern limb of the eddy were also considered to estimate divergence and vorticity. The results indicate convergence (divergence) and downwelling (upwelling) at scales of 20–50 km near the northeastern (northwestern) edge of the eddy, in agreement with the quasi-geostrophic theory. Vertically, the eddy extends mostly down to 250 m depth, with a warm, low-salinity and low-density signature and with geostrophic currents near 50 cm/s in the top layer (down to ~80 m) reducing to less than 10 cm/s near 250 m. Near the surface, colder water is advected into it.
Stabilities of duplexes and triplexes of dA19 + dT19 with alternating methylphosphonate and phosphodiester linkages. (1993)

Results from UV thermal melting, polyacrylamide gel electrophoresis and circular dichroism (CD) experimetns are used to compare stabilities of complexes formed from 1:1 and 1:2 molar ratio mixtures of dA19 or dA*P19 (alternating phosphodiester and methylphosphonate linkages on the A chain) with dT19 or dT*P19 (alternating phosphodiester and methylphosphonate linkages on the T chain). Complexes formed from 1:1 and 1:2 molar ratio mixtures of dA*P19 with dT19 are more stable than the respective unmodified 'parent' complexes, but less stable than complexes of dA*19 (17 methylphosphonates on the A chain) + dT19. At 0.1 M Na+ complexes containing dT*P19 are less stable than those with dT19, yet more stable than complexes containing the highly modified dT*19 (17 methylphosphonates on the T chain). A value of 2.6 kcal/mol base triplets is calculated for delta H of dA19.2dT19-->dA19.dT19+dT19.
Visual recognition and detection under bounded computational resources (2010)

Visual recognition and detection are computationally intensive tasks and current research efforts primarily focus on solving them without considering the computational capability of the devices they run on. In this paper we explore the challenge of deriving methods that consider constraints on computation, appropriately schedule the next best computation to perform and finally have the capability of producing reasonable results at any time when a solution is required. We specifically derive an approach for the task of object category localization and classification in cluttered, natural scenes that can not only produce anytime results but also utilize the principle of value-of-information in order to provide the most recognition bang for the computational buck. Experiments on two standard object detection challenges show that the proposed framework can triage computation effectively and attain state-of-the-art results when allowed to run till completion. Additionally, the real benefit of the proposed framework is highlighted in the experiments where we demonstrate that the method can provide reasonable recognition results even if the procedure needs to terminate before completion.
TiIV-Mediated Reactions between Primary Amines and Secondary Carboxamides:  Amidine Formation Versus Transamidation (2007)

Titanium(IV)-mediated reactions between primary amines and secondary carboxamides exhibit different outcomes, amidine formation versus transamidation, depending on the identity of the TiIV complex used and the reaction conditions employed. The present study probes the origin of this divergent behavior. We find that stoichiometric TiIV, either Cp*TiIV complexes or Ti(NMe2)4, promotes formation of amidine and oxotitanium products. Under catalytic conditions, however, the outcome depends on the identity of the TiIV complex. Competitive amidine formation and transamidation are observed with Cp*TiIV complexes, generally favoring amidine formation. In contrast, the use of catalytic Ti(NMe2)4 (< or =20 mol %) results in highly selective transamidation. The ability of TiIV to avoid irreversible formation of oxotitanium products under the latter conditions has important implications for the use of TiIV in catalytic reactions.
Distributed Multicell Beamforming With Limited Intercell Coordination (2010)

This paper studies distributed optimization schemes for multicell joint beamforming and power allocation in time-division-duplex (TDD) multicell downlink systems where only limited-capacity intercell information exchange is permitted. With an aim to maximize the worst-user signal-to-interference-and-noise ratio (SINR), we devise a hierarchical iterative algorithm to optimize downlink beamforming and intercell power allocation jointly in a distributed manner. The proposed scheme is proved to converge to the global optimum. For fast convergence and to reduce the burden of intercell parameter exchange, we further propose to exploit previous iterations adaptively. Results illustrate that the proposed scheme can achieve near-optimal performance even with a few iterations, hence providing a good tradeoff between performance and backhaul consumption. The performance under quantized parameter exchange is also examined.
