Antioxidant Capacity and Antimutagenic Potential ofMurraya koenigii (2013)

It is well known that the intake of antioxidants with increased consumption of fruits and vegetables and medicinal herbs contributes towards reduced risk of certain diseases including cancers. This study aims to evaluate the broad-spectrum antioxidant and antimutagenic activities as well as to elucidate phytochemical profile of an Indian medicinal plant Murraya koenigii (curry) leaves. Leaves of the plant were successively fractionated in various organic solvents. Benzene fraction demonstrated the highest phenolic content followed by petroleum ether. The benzene fraction showed maximum antioxidant activity in all tested assays, namely, phosphomolybdenum, 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical, ferric reducing antioxidant power (FRAP) and cupric reducing antioxidant capacity (CUPRAC) assays. Based on the promising broad-spectrum antioxidant activity, benzene fraction was further evaluated for antimutagenic activity and showed a dose-dependent antimutagenic response in Ames Salmonella mutagenicity assay. It inhibited 72-86% mutagenicity induced by sodium azide, methyl methanesulfonate, benzo(a)pyrene, and 2-aminoflourene at the maximum tested concentration (100 μg/mL) in Salmonella typhimurium tester strains. At least 21 compounds were detected by GC/MS. The findings clearly demonstrated that phenolic-rich benzene fraction has promising broad-spectrum antioxidant and antimutagenic property and needs further evaluation to exploit its therapeutic potential.

Liquid water, by near-ambient pressure XPS (2019)

Near ambient pressure x-ray photoelectron spectroscopy (NAP-XPS) is a less traditional form of XPS that allows samples to be analyzed at relatively high pressures, i.e., at ca. 2500 Pa, or higher in some cases. With NAP-XPS, XPS can be used to analyze moderately volatile liquids, biological samples, porous materials, and/or polymeric materials that outgas significantly. In this submission, we show survey, O 1s, O KLL, and valence band NAP-XPS spectra from liquid water, a material that could not be analyzed at moderate pressures by conventional approaches. The O 1s signal was fit to two components attributed to liquid and vapor phase water. The carbon in the survey spectrum is attributed to contaminants in the water and/or adventitious carbon.

Discovery of 3-(5-Chloro-2-furoyl)-3,7-diazabicyclo[3.3.0]octane (TC-6683, AZD1446), a Novel Highly Selective α4β2 Nicotinic Acetylcholine Receptor Agonist for the Treatment of Cognitive Disorders (2012)

Diversification of essential nicotinic cholinergic pharmacophoric elements, i.e., cationic center and hydrogen bond acceptor, resulted in the discovery of novel potent α4β2 nAChR selective agonists comprising a series of N-acyldiazabicycles. Core characteristics of the series are an exocyclic carbonyl moiety as a hydrogen bond acceptor and endocyclic secondary amino group. These features are positioned at optimal distance and with optimal relative spatial orientation to provide near optimal interactions with the receptor. A novel potent and highly selective α4β2 nAChR agonist 3-(5-chloro-2-furoyl)-3,7-diazabicyclo[3.3.0]octane (56, TC-6683, AZD1446) with favorable pharmaceutical properties and in vivo efficacy in animal models has been identified as a potential treatment for cognitive deficits associated with psychiatric or neurological conditions and is currently being progressed to phase 2 clinical trials as a treatment for Alzheimer's disease.
Charge Transport through Self‐Assembled Monolayers of Monoterpenoids (2019)

The nature of the processes at the origin of life that selected specific classes of molecules for broad incorporation into cells is controversial. Among those classes selected were polyisoprenoids and their derivatives. This paper tests the hypothesis that polyisoprenoids were early contributors to membranes in part because they (or their derivatives) could facilitate charge transport by quantum tunneling. It measures charge transport across self-assembled monolayers (SAMs) of carboxyl-terminated monoterpenoids (O<sub>2</sub> C(C<sub>9</sub> HX)) and alkanoates (O<sub>2</sub> C(C<sub>7</sub> HX)) with different degrees of unsaturation, supported on silver (Ag<sup>TS</sup> ) bottom electrodes, with Ga<sub>2</sub> O<sub>3</sub> /EGaIn top electrodes. Measurements of current density of SAMs of linear length-matched hydrocarbons-both saturated and unsaturated-show that completely unsaturated molecules transport charge faster than those that are completely saturated by approximately a factor of ten. This increase in relative rates of charge transport correlates with the number of carbon-carbon double bonds, but not with the extent of conjugation. These results suggest that polyisoprenoids-even fully unsaturated-are not sufficiently good tunneling conductors for their conductivity to have favored them as building blocks in the prebiotic world.
Limits to On-Chip Power Conversion With Thin Film Inductors (2013)

Successful implementation of on-chip power conversion using ferromagnetic inductors requires both high power efficiency and high power density. The theoretical limits to power density and efficiency possible with thin film ferromagnetic inductors in a buck converter topology with and without coupling are explored. Power density can be related to energy density of the inductor, while efficiency can be related to Q and the DC resistance loss of the inductor. To achieve 100 <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex Notation="TeX">${\rm A/cm}^{2}$</tex></formula> for a 100 MHz 2:1 V converter witha 90% inductor efficiency, a peak Q of more than 8 is required with an energy storage of more than 5 <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">${\rm nJ/mm}^{2}$</tex></formula> . Using coupling, the power density can be further increased, but is ultimately limited by DC resistance loss in the coils. Figures of merit (FOM) for comparing inductors of various designs are also discussed.
Integrated polymer optoelectronic time delay device for an x-band phased array antenna system (2006)

A 4-bit polymer optoelectronic true time delay device is demonstrated. The device is composed of monolithically integrated, low loss, passive polymer waveguide delay lines and 2x2 polymer thermo-optic switches. Waveguide junction offsets and air trenches simultaneously reduce the bending loss and device area. Simulations are used to optimize the trench and offset structures for fabrication. The 16 time delays generated by the device are measured to range from 0 to 177 ps in 11.8 ps increments. The packaged device has an insertion loss of 14.5 dB and the delay switching speed is 2 ms. The delays generated by the device are suitable for steering a 1D or 2D sub-array of an X-band phased array antenna system.
Opto-electronic oscillators (2002)

Oscillators are devices that convert energy from a continuous source to a periodically varying signal. They represent the physical realization of a fundamental basis of all physics, the harmonic oscillator, and they are perhaps the most widely used devices in modern day society. Today a variety of mechanical (such as the pendulum), electromagnetic (such as LC and cavity based), and atomic (such as maser and laser) oscillators provide a diverse range in the approximation to the realization of the ideal harmonic oscillator. The degree of spectral purity and stability of the output signal of the oscillator is the measure of the accuracy of this approximation, and is fundamentally dependent on the energy storage ability of the oscillator, determined by the resistive loss (generally frequency dependent) of the various elements in the oscillator.
Deployable Convex Generalized Cylindrical Surfaces Using Torsional Joints (2021)

Abstract The ability to deploy a planar surface to a desired convex profile with a simple actuation can enhance foldable or morphing airfoils, deployable antennae and reflectors, and other applications where a specific profile geometry is desired from a planar sheet. A model using a system of rigid links joined by torsional springs of tailorable stiffness is employed to create an approximate curved surface when two opposing tip loads are applied. A system of equations describing the shape of the surface during deployment is developed. The physical implementation of the model uses compliant torsion bars as the torsion springs. A multidimensional optimization algorithm is presented to place joints to minimize the error from the rigid-link approximation and account for additional manufacturing and stress considerations in the torsion bars. A proof is presented to show that equal torsion spring spacing along the horizontal axis of deployed parabolic profiles will result in minimizing the area between the model’s rigid-link approximation and smooth curve. The model is demonstrated through the physical construction of a deployable airfoil surface and a metallic deployable parabolic reflector.
Basic physics of xylophone and marimba bars (2001)

The frequency-dependent wave velocity and nonsinusoidal spatial dependence found for transverse waves in finite vibrating bars stands in stark contrast to the solutions to the one-dimensional wave equation, for example for the idealized vibrating string. The difference is particularly important when the resulting vibrations are used to produce music. Here, the appropriate approximate equations for transverse vibrations on a uniform bar are developed and compared to measurements using wooden bars. The results are extended using a simple finite element model to provide a means to predict normal mode behavior in nonuniform wooden bars such as those used for xylophones, marimbas, and related musical instruments.
Analysis on electromagnetic field leaked from wireless power transfer system for electric vehicle located at case study house (2014)

In recent years, toward the commercialization of the wireless power transfer (WPT) system for the electric vehicle, the associated technologies such as various transfer methods, coil configurations, operating frequencies, and the leaked electromagnetic fields have been discussed actively. In this paper, the leaked electromagnetic field distributions from the WPT system located around the case study house are presented. The attenuation characteristics by the wall of the house are measured at the real experimental house and calculated by using the electromagnetic field simulation. The result shows that the calculated and measured attenuation characteristics are almost in agreement with each other.
Microglial nodule encephalitis: limited CNS infection despite disseminated systemic cryptococcosis. (1997)

A 28-year-old patient with AIDS was found at autopsy to have disseminated cryptococcal infection involving the lungs, spleen, lymph nodes, kidneys, gastrointestinal tract, thyroid, bone marrow, and liver. Despite widespread organ dissemination the patient did not have clinical or pathological evidence of meningitis. Microscopic examination of the brain showed cryptococci limited to the brainstem and basal ganglia; microglial nodules with multinucleate giant cells, a histological hallmark of HIV-1 encephalitis, were shown to contain Cryptococcus neoformans. This feature may suggest a form of synergism between HIV-1 and Cryptococcus neoformans. This case demonstrates an unusual form of cryptococcal neurotropism with limited CNS involvement.

DYSPHAGIA AND NEUROPATHIC FACIAL PAIN TREATED WITH MOTOR CORTEX STIMULATION (2009)

OBJECTIVE We report on a patient with a neuropathic facial pain syndrome, including elements of trigeminal neuralgia, glossopharyngeal neuralgia, and dysphagia. After failing medical and surgical decompressive treatments, the patient underwent implantation of a motor cortex stimulation (MCS) system. CLINICAL PRESENTATION A 54-year-old woman presented with a 14-year history of left-sided facial pain, throat pain, and associated nausea and vomiting. The patient failed several open surgical and percutaneous procedures for her facial pain syndrome. Additionally, several medication trial attempts were unsuccessful. Imaging studies were normal. INTERVENTION The patient underwent placement of a right-sided MCS system for treatment of her neuropathic facial pain syndrome. The procedure was tolerated well, and the trial stimulator provided promising results. The permanent MCS generator needed to be reprogrammed at the time of the 5-week follow-up visit to optimize symptom relief. The patient demonstrated dramatic improvements in her neuropathic facial and oral pain, including improvements in swallowing toleration, after the 5-week follow-up examination with subthreshold MCS. A decline in treatment efficacy also occurred 2 years after implantation due to generator depletion. Symptom improvement returned with stimulation after the generator was replaced. CONCLUSION A novel implantable MCS system was used to treat this patient's neuropathic facial pain. Durable improvements were noted not only in her facial pain, but also in swallowing toleration. The ultimate role of MCS in the treatment of pain conditions is still not well-defined but might play a part in refractory cases and, as in this case, might improve other functional issues, including dysphagia.
Using Models To Provide Predicted Ranges For Building Human Interfaces (2013)

Most building energy consumption dashboards provide a snapshot of building performance; others provide detailed historical data for comparison to current usage. This paper discusses the Building Agent platform, which was developed and deployed in a campus setting at the National Renewable Energy Laboratory as part of an effort to maintain the aggressive energy performance achieved in newly constructed office buildings and laboratories. The Building Agent provides aggregated and coherent access to building data, including electric energy, thermal energy, temperatures, humidity, and lighting levels, and occupant comfort feedback, which are displayed in various manners for visitors, occupants, facility managers, and researchers. This paper focuses on the development of visualisations for facility managers, or an energy performance assurance provider, where metered data are used to generate models that provide live predicted ranges of building performance by end use. These ranges provide simple, visual contexts for displayed performance data without requiring users to assess historical information or trends. Several energy modelling techniques were explo red, including static lookup-based performance targets, reduced-order models derived from historical data using main effect variables such as solar radiance for lighting performance, and integrated energy models using a whole-building energy simulation program. This paper describes the new building construction backdrop that has motivated this work, the system architecture providing access to building data, the various modelling approaches currently employed, and the visualisation methods used to display performance and modelled data.

Fast planning of well conditioned trajectories for model learning (2014)

This paper discusses the problem of planning well conditioned trajectories for learning a class of nonlinear models such as the imaging model of a camera and the multibody dynamic model of a robot. In such model learning problems, the model parameters can be linearly decoupled from system variables in the feature space. The learning accuracy and robustness against measurement noise and unmodeled response depend largely on the condition number of the data matrix. A new method is proposed to plan well conditioned trajectories efficiently by using low-discrepancy sequences and matrix subset selection. Application examples show promising results.
Properties of the planar poly(3-octylthiophene)/aluminum Schottky barrier diode (1992)

Formation and characterization of planar polymer Schottky barrier diodes are presented. Electrical characteristics of planar aluminium-poly(3-octylthiophene) Schottky barrier diodes are studied with emphasis on the current transport mechanisms. The device exhibits nearly ideal diode behavior in dark with an ideality factor of n=1.2. Temperature dependence of the current-voltage characteristics of the diode is studied in the range 170–370 K. Agreement with the diffusion theory of metal-semiconductor rectification is demonstrated for high temperatures T≳300 K. For temperatures less than room temperatures tunneling is proposed to be the dominant current transport mechanism.
Revisiting kd-tree for Nearest Neighbor Search (2019)

\kdtree \citefriedman1976algorithm has long been deemed unsuitable for exact nearest-neighbor search in high dimensional data. The theoretical guarantees and the empirical performance of \kdtree do not show significant improvements over brute-force nearest-neighbor search in moderate to high dimensions. \kdtree has been used relatively more successfully for approximate search \citemuja2009flann but lack theoretical guarantees. In the article, we build upon randomized-partition trees \citedasgupta2013randomized to propose \kdtree based approximate search schemes with $O(d łog d + łog n)$ query time for data sets with n points in d dimensions and rigorous theoretical guarantees on the search accuracy. We empirically validate the search accuracy and the query time guarantees of our proposed schemes, demonstrating the significantly improved scaling for same level of accuracy.
Load-side acceleration control for industrial robot arm with axial torsion (2012)

This paper proposes a new acceleration control method for industrial robots. To achieve high-speed and high-precision path tracking control, the motion control system must be able to control the arm acceleration. However, it is difficult to directly control the arm acceleration, because the speed reduction mechanism of industrial robots has axial torsion. To solve this problem, this paper proposes a new acceleration control method based on an inverse system. The proposed method designs an inverse transfer function system from the current command for arm acceleration. Acceleration control is achieved by the feed-forward control input designed from the inverse system. In addition, a robust feedback control system is designed to compensate for the dynamic disturbance torque and parameter variation. The effectiveness of the proposed method is confirmed by experimental results using a 2-DOF robot manipulator.
Predicting Top-of-Atmosphere Thermal Radiance Using MERRA-2 Atmospheric Data with Deep Learning (2017)

Image data from space-borne thermal infrared (IR) sensors are used for a variety of applications, however they are often limited by their temporal resolution (i.e., repeat coverage). To potentially increase the temporal availability of thermal image data, a study was performed to determine the extent to which thermal image data can be simulated from available atmospheric and surface data. The work conducted here explored the use of Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) developed by The National Aeronautics and Space Administration (NASA) to predict top-of-atmosphere (TOA) thermal IR radiance globally at time scales finer than available satellite data. For this case study, TOA radiance data was derived for band 31 (10.97 μ m) of the Moderate-Resolution Imaging Spectroradiometer (MODIS) sensor. Two approaches have been followed, namely an atmospheric radiative transfer forward modeling approach and a supervised learning approach. The first approach uses forward modeling to predict TOA radiance from the available surface and atmospheric data. The second approach applied four different supervised learning algorithms to the atmospheric data. The algorithms included a linear least squares regression model, a non-linear support vector regression (SVR) model, a multi-layer perceptron (MLP), and a convolutional neural network (CNN). This research found that the multi-layer perceptron model produced the lowest overall error rates with an root mean square error (RMSE) of 1.36 W/m 2 ·sr· μ m when compared to actual Terra/MODIS band 31 image data. These studies found that for radiances above 6 W/m 2 ·sr· μ m, the forward modeling approach could predict TOA radiance to within 12 percent, and the best supervised learning approach can predict TOA to within 11 percent.
Purification and characterization of an extracellular protease from Pseudomonas cepacia (1989)

An extracellular proteinase (PSCP) produced by Pseudomonas cepacia was purified from culture supernatants by ammonium sulfate precipitation, anion exchange chromatography on DEAE-Sephacel, and G200 gel filtration chromatography. The protease has an apparent Mr of 34,000 by electrophoresis. Substrates cleaved by the protease include gelatin, hide powder, and collagen but not human immunoglobulin G (IgG), IgM, secretory IgA, or IgA. The enzyme had the characteristics of a metalloprotease, a pH optimum of 6, and a temperature optimum of 45 degrees C. Intratracheal instillation of purified PSCP into rat lungs produced a bronchopneumonia characterized by polymorphonuclear cell infiltration and proteinaceous exudation into large airways. Rats responded immunologically to active immunization with PSCP, but this response was not protective against subsequent lung infection with P. cepacia. PSCP was shown to have antigenic similarity with Pseudomonas aeruginosa elastase by an immunoblotting technique. Sera from 10 cystic fibrosis patients, with and without a previous history of P. cepacia colonization, were shown to possess antibody reactive against PSCP.
