Survival ofBeauveria bassiana(Deuteromycetes: Moniliales) Conidia on Cadavers of Cowpea Pests Stored Outdoors and in Laboratory in Brazil (1986)

Cowpea pest cadavers with Beauveria bassiana (Balsamo) mycoses were stored outdoors both under exposure to sunlight and rainfall and under protected conditions, and in the laboratory at 4 and 27°C over prolonged intervals. Conidia on cowpea curculio adults stored outdoors under protected conditions remained stable (i.e., without loss of viability) for at least 16 weeks and with only a slight decline in germinative ability for up to 24 weeks. Under the same outdoor conditions, conidia on chrysomelid beetle cadavers also survived well. In contrast, infected cowpea pest cadavers stored outdoors under direct exposure to rainfall and sunlight lost most of the conidia from their cuticles within 2 weeks; however, among the conidia that remained on the cadavers no decline in viability could be detected. The virulence of B. bassiana strains to their host insects was not correlated with the stability of conidia on host cadavers stored outdoors.

Desialylation of Neisseria gonorrhoeae Lipooligosaccharide by Cervicovaginal Microbiome Sialidases: The Potential for Enhancing Infectivity in Men (2016)

Previous studies have demonstrated that Neisseria gonorrhoeae sialylates the terminal N-acetyllactosamine present on its lipooligosaccharide (LOS) by acquiring CMP-N-acetyl-5-neuraminic acid upon entering human cells during infection. This renders the organism resistant to killing by complement in normal human serum. N-acetyllactosamine residues on LOS must be free of N-acetyl-5-neuraminc acid (Neu5Ac; also known as sialic acid) in order for organisms to bind to and enter urethral epithelial cells during infection in men. This raises the question of how the gonococcus infects men if N-acetyllactosamine residues are substituted by Neu5Ac during infection in women. Here, we demonstrate that women with gonococcal infections have levels of sialidases present in cervicovaginal secretions that can result in desialylation of (sialylated) gonococcal LOS. The principle sialidases responsible for this desialylation appear to be bacterial in origin. These studies suggest that members of the cervicovaginal microbiome can modify N. gonorrhoeae, which will enhance successful transmission to men.
Catalytic Enantioselective Synthesis of Bicyclic Lactam N,S‐Acetals in One Pot by Cascade Transformations (2019)

A versatile strategy for the enantioselective synthesis of bicyclic lactam N , S ‐acetals by one‐pot cascade transformations is disclosed. The transformation of readily available substrates is promoted by chiral amines and creates bicyclic or tricyclic lactam N , S ‐acetals with high chemo‐ and stereoselectivity (up to &gt; 99.5:0.5 dr and &gt; 99 % ee ) in one‐pot operations.
Photonic Devices in Some Low Dimensional Systems (2009)

Results of using low temperature growth approach (lower than 100 oC) to control the growth of ZnO nanowires are presented. The effect of different parameters on the growth is highlighted. Time resolved low temperature photoluminescence (PL) was used to investigate surface recombination and its relation to the nanowires diameters. Finally hybrid light emitting diodes (LEDs) based on p-type polymers and n-ZnO nanowires grown on amorphous substrates is fabricated and characterized. This hybrid organic-inorganic technology can provide a suitable replacement of conventional lighting tubes.

Structures, Properties, and Performances—Relationships of Polymeric Membranes for Pervaporative Desalination (2019)

For the fulfilment of increasing global demand and associated challenges related to the supply of clean-and-safe water, PV has been considered as one of the most attractive and promising areas in desalinating salty-water of varied salinities. In pervaporative desalination, the sustainability, endurance, and structural features of membrane, along with operating parameters, play the dominant roles and impart paramount impact in governing the overall PV efficiency. Indeed, polymeric- and organic-membranes suffer from several drawbacks, including inferior structural stability and durability, whereas the fabrication of purely inorganic membranes is complicated and costly. Therefore, recent development on the high-performance and cost-friendly PV membrane is mostly concentrated on synthesizing composite- and NCP-membranes possessing the advantages of both organic- and inorganic-membranes. This review reflects the insights into the physicochemical properties and fabrication approaches of different classes of PV membranes, especially composite- and NCP-membranes. The mass transport mechanisms interrelated to the specialized structural features have been discussed. Additionally, the performance potential and application prospects of these membranes in a wide spectrum of desalination and wastewater treatment have been elaborated. Finally, the challenges and future perspectives have been identified in developing and scaling up different high-performance membranes suitable for broader commercial applications.

Mincer-zarnovitz quantile and expectile regressions for forecast evaluations under asymmetric loss functions: Working paper series--14-01 (2014)

Forecast is pervasive in all areas of applications in business and daily life and, hence, evaluating the accuracy of a forecast is important for both the generators and consumers of forecasts. There are two aspects in forecast evaluation: (1) measuring the accuracy of past forecasts using some summary statistics and (2) testing the optimality properties of the forecasts through some diagnostic tests. On measuring the accuracy of a past forecast, we illustrate that the summary statistics used should match the loss function that was used to generate the forecasts. If there is strong evidence that an asymmetric loss function has been used in the generation of a forecast, then a summary statistic that corresponds to that asymmetric loss function should be used in assessing the accuracy of the forecast instead of the popular RMSE or MAE. On testing the optimality of the forecasts, we demonstrate how the quantile regressions and expectile regressions set in the prediction-realization framework of Mincer and Zarnowitz (1969) can be used to recover the unknown parameter that controls the potentially asymmetric loss function used in generating the past forecasts. Finally, we apply the prediction-realization framework to the Federal Reserve's economic growth forecast and forecast sharing in a PC manufacturing supply chain. We find that the Federal Reserves values over prediction approximately 1.5 times more costly than under prediction. We also find that the PC manufacturer weighs positive forecast errors (under forecasts) about four times as costly as negative forecast errors (over forecasts).
A MAC policy framework for multilevel relational databases (1996)

We develop a formal framework of MAC policies in multilevel relational databases. We identify the important components of MAC policies and their desirable properties. The framework provides a basis for systematically specifying MAC policies and characterizing their potential mismatches. Based on the framework, we compare and unify the MAC policies and policy components that are proposed in the literature or imposed in existing systems. Our framework could be used to capture and resolve MAC policy mismatches in the trusted interoperation of heterogeneous multilevel relational databases.

Active Control of Turbulent Boundary Layer Induced Sound Radiation from Multiple Aircraft Panels (2002)

The objective of this work is to experimentally investigate active structural acoustic control of turbulent boundary layer (TBL) induced sound radiation from multiple panels on an aircraft sidewall.One possible approach for controlling sound radiation from multiple panels is a multi-input/multi-output scheme which considers dynamic coupling between the panels.Unfortunately, this is difficult for more than a few panels, and is impractical for a typical aircraft which contains several hundred such panels.An alternative is to implement a large number of independent control systems.Results from the current work demonstrate the feasibility of reducing broadband radiation from multiple panels utilizing a single-input/single-output (SISO) controller per bay, and is the first known demonstration of active control of TBL induced sound radiation on more than two bays simultaneously.The paper compares sound reduction for fully coupled control of six panels versus independent control on each panel.An online adaptive control scheme for independent control is also demonstrated.This scheme will adjust for slow time varying dynamic systems such as fuselage response changes due to aircraft pressurization, etc.
Combining Static Code Analysis and Machine Learning for Automatic Detection of Security Vulnerabilities in Mobile Apps (2016)

Mobile devices have revolutionized many aspects of our lives. Without realizing it, we often run on them programs that access and transmit private information over the network. Integrity concerns arise when mobile applications use untrusted data as input to security-sensitive computations. Program-analysis tools for integrity and confidentiality enforcement have become a necessity. Static-analysis tools are particularly attractive because they do not require installing and executing the program, and have the potential of never missing any vulnerability. Nevertheless, such tools often have high false-positive rates. In order to reduce the number of false positives, static analysis has to be very precise, but this is in conflict with the analysis' performance and scalability, requiring a more refined model of the application. This chapter proposes Phoenix, a novel solution that combines static analysis with machine learning to identify programs exhibiting suspicious operations. This approach has been widely applied to mobile applications obtaining impressive results.
Effect of Magnetic Annealing on the Structure and Magnetic Properties of Highly Resistive Co-Based Films. (1995)

This paper studies the effect of magnetic field annealing on the structure and properties of highly electrically resistive Co-based soft magnetic films, prepared by RF reactive magnetron sputtering with (N2+Ar) gases. After annealing near 300°C in a static magnetic field, Co-Al-N films whose nitrogen content is lower than their Al content exhibit almost exactly the calculated μ-f characteristics. TEM observation reveals that these films are granular with a very fine network structure, which has a considerable number of connections among granules. With increasing nitrogen content, the size of the granules decreases, and the intergranule composition approaches that of AlN. It follows that improved μ-f characteristics can be obtained in Co-Al-N film of an appropriate composition and structure.
J0450301 Failure and damage evaluation of laser joints in carbon fiber reinforced thermo-plastics and stainless steel (2015)

Carbon fiber reinforced thermoplastics (CFRTP), which is expected to reduce the weight of transportations and stainless steel (SUS304) were joined in the form of lap joint by a semiconductor laser (3kW, CW(continuous wave), 0.8-1.2m/min) using insert materials of thermoplastic elastomer sheet. When the irradiation speed is 1.0m/min, the shear strength was the highest showing cohesive failure at the joining area. While, 0.8m/min and 1.2 m/min specimens were lower values than 1.0m/min specimens showing the interfacial failure. The fatigue strength was very similar results to the tensile shear strength. These laser-joint specimens were lower shear/fatigue strength than adhesive-joint specimens. From the results of thermo-elastic stress analysis using the thermography, the stress concentration was observed at the joining area just before the fatigue failure. From the characterizing energy dissipation and degradation evaluation, the 1.0m/min laser-joint specimens showed higher value than the adhesive joint specimens during fatigue tests. It can be assumed that the laser-joint specimen accelerated the process of failure as compared with the adhesive-joint specimen.
Acoustically controlled enhancement of molecular sensing to assess oxidative stress in cells (2013)

We demonstrate a microfluidic platform for the controlled aggregation of colloidal silver nanoparticles using surface acoustic waves (SAWs), enabling surface enhanced Raman scattering (SERS) analysis of oxidative damage in cells. We show that by varying the frequency and the power of the acoustic energy, it is possible to modulate the aggregation of the colloid within the sample and hence to optimise the SERS analysis.
Frontal Convergence and Vertical Velocity Measured by Drifters in the Alboran Sea (2021)

Abstract Horizontal and vertical motions associated with mesoscale (10–100 km) and submesoscale (1–10 km) features, such as fronts, meanders, eddies, and filaments, play a critical role in redistributing physical and biogeochemical properties in the ocean. This study makes use of a multiplatform data set of 82 drifters, a Lagrangian float, and profile timeseries of temperature and salinity, obtained in a ∼1‐m/s semipermanent frontal jet in the Alboran Sea as part of CALYPSO (Coherent Lagrangian Pathways from the Surface Ocean to Interior). Drifters drogued at ∼1‐m and 15‐m depth capture the mesoscale and submesoscale circulation aligning along the perimeter of fronts due to horizontal shear. Clusters of drifters are used to estimate the kinematic properties, such as vorticity and divergence, of the flow by fitting a bivariate plane to the horizontal drifter velocities. Clusters with submesoscale length scales indicate normalized vorticity ζ / f &gt; 1 with Coriolis frequency f and normalized divergence of (1) occurring in patches along the front, with error variance around 10%. By computing divergence from drifter clusters at two different depths, we estimate minimum vertical velocity of (−100 m day −1 ) in the upper 10 m of the water column. These results are at least twice as large as previous estimates of vertical velocity in the region. Location, magnitude, and timing of the convergence are consistent with behavior of a Lagrangian float subducting in the center of a drifter cluster. These results improve our understanding of frontal subduction and quantify convergence and vertical velocity using Lagrangian tools.
An Electron Time-of-Flight Method Applied to Charge Transport Dynamics in a Cobalt Bipyridine Redox Polyether Hybrid (1997)

An electrochemical time-of-flight technique is employed in the investigation of charge transport dynamics in a cobalt bipyridine redox polyether hybrid. Measurements of the apparent diffusion coefficient, DAPP, provide insight into electron self-exchange reactions in the undiluted molten metal complex. Results from time-of-flight measurements are compared to those from potential step chronoamperometry and cyclic voltammetry; good agreement is observed. Peak shapes are compared with simulations from a previous report; disparities noted are ascribed to differences in the potential pulse profile employed.

Recombinant Human Immunodeficiency Virus Type 1 Reverse Transcriptase Is Heterogeneous (1996)

Recombinant wild type (wt) and T215Y HIV-1 reverse transcriptase (RT) were isolated using three methods designated A, B, and C. The three samples of wt RT were kinetically indistinguishable with respect to dTTP turnover on poly(rA).p(dT)10. However, whereas the kinetic constants for dTTP and AZTTP for both T215Y B and T215Y C were similar to those of wt protein, T215Y A exhibited a twofold increase in Km value for dTTP and a 13-fold increase in Ki value for AZTTP with respect to wt protein purified in the same manner. We further investigated this observation by studying the denaturation of wt RT by urea. The urea denaturation curves monitored by fluorescence and circular dichroism spectroscopy were not coincident with the denaturation curve monitored by enzyme activity and yielded Cm values (the concentration of urea at which 50% of the protein is denatured) of 4.1 and 2.0 M urea, respectively. The noncoincidence of the transition curves reflects two separable, sequential, noncooperative conformational changes in the molecule: (a) from a catalytically active to an inactive conformation, and (b) from a catalytically inactive to a denatured, unfolded conformation. We therefore used denaturation as detected by changes in enzyme activity to compare the conformational stability of the three samples of wt and T215Y RT A, B, and C. The Cm values for T215Y RT did not differ from those of the respective wt; however, differences in Cm values were noted depending on how the protein was isolated. This suggested that the heterogeneity of the recombinant RT was due to small differences in conformation at or near the active site.
Combined Treatment with Surfactant and Specific Immunoglobulin Reduces Bacterial Proliferation in Experimental Neonatal Group B Streptococcal Pneumonia (1999)

Neonates suffering from group B streptococcal (GBS) pneumonia often lack type-specific opsonizing antibodies. We studied the influence of combined intratracheal treatment with surfactant and a specific antibacterial polyclonal antibody (IgG fraction) on bacterial proliferation and lung function in an animal model of GBS pneumonia. Near-term newborn rabbits received an intratracheal injection of either the specific IgG antibody, nonspecific IgG, surfactant, a mixture of surfactant and the antibody, or 0.9% saline. At 30 min the rabbits were infected with a standard dose (10(8)) of the encapsulated GBS strain 090 Ia. After 5 h of mechanical ventilation the mean estimated increase in bacterial number in lung homogenate (log10 colonies/g) was 0.76 in the antibody group, 0.92 in the nonspecific IgG group, 0.55 in the surfactant group, and 1.29 in the saline group. A mean decrease in bacterial number (-0.05) was observed in the group that received combined treatment with surfactant and antibody (p < 0.05 versus all other groups). Lung-thorax compliance was significantly higher in both groups of surfactant-treated animals compared with saline or IgG treatment. We conclude that in experimental neonatal GBS pneumonia combined treatment with surfactant and a specific immunoglobulin against GBS reduced bacterial proliferation more effectively than either treatment alone.
Optimum Adaptive Modulation and Channel Coding Scheme for Frequency Domain Channel-Dependent Scheduling in OFDM Based Evolved UTRA Downlink (2009)

In the Evolved UTRA (UMTS Terrestrial Radio Access) downlink, Orthogonal Frequency Division Multiplexing (OFDM) based radio access was adopted because of its inherent immunity to multipath interference and flexible accommodation of different spectrum arrangements. This paper presents the optimum adaptive modulation and channel coding (AMC) scheme when resource blocks (RBs) is simultaneously assigned to the same user when frequency and time domain channel-dependent scheduling is assumed in the downlink OFDMA radio access with single-antenna transmission. We start by presenting selection methods for the modulation and coding scheme (MCS) employing mutual information both for RB-common and RB-dependent modulation schemes. Simulation results show that, irrespective of the application of power adaptation to RB-dependent modulation, the improvement in the achievable throughput of the RB-dependent modulation scheme compared to that for the RB-common modulation scheme is slight, i.e., 4 to 5%. In addition, the number of required control signaling bits in the RB-dependent modulation scheme becomes greater than that for the RB-common modulation scheme. Therefore, we conclude that the RB-common modulation and channel coding rate scheme is preferred, when multiple RBs of the same coded stream are assigned to one user in the case of single-antenna transmission.
Multipulse Double-Quantum Magnetometry with Near-Surface Nitrogen-Vacancy Centers (2014)

We discuss multipulse magnetometry that exploits all three magnetic sublevels of the S=1 nitrogen-vacancy center in diamond to achieve enhanced magnetic field sensitivity. Based on dual frequency microwave pulsing, the scheme is twice as sensitive to ac magnetic fields as conventional two-level magnetometry. We derive the spin evolution operator for dual frequency microwave excitation and show its effectiveness for double-quantum state swaps. Using multipulse sequences of up to 128 pulses under optimized conditions, we show enhancement of the SNR by up to a factor of 2 in detecting NMR statistical signals, with a 4× enhancement theoretically possible.
