Effect of Shape Anisotropy on Stop-Band Response of Fe and Permalloy Based Tunable Microstrip Filters (2004)

The magnetic/dielectric hybrid transmission line structures provide a new class of microwave/millimeter wave devices, useful for signal processing. Reduction of device dimensions in these magnetic monolithic microwave integrated circuits (M-MMICs) is important from the cost and reliability point of view. Here, we explore the transmission characteristics of Fe and Permalloy based microstrip filters with microstrips of different widths, lengths, and thicknesses. The gyromagnetic resonance occurs at microwave frequencies of up to 12 GHz for Fe and 5 GHz for Permalloy, even in the absence of any dc magnetic field. The resulting absorption yields the stop-band behavior of the device. Our microstrip geometry significantly boosts the operational frequency due to an induced shape-anisotropy. Different geometries induce different demagnetization factors and hence different resonance frequencies. We calculate the frequency-boosting characteristics of the devices due to induced shape-anisotropy and observed a good match to our measurements.
Bile Acid Replacement Therapy with Cholylsarcosine for Short-Bowel Syndrome (1999)

Cholylsarcosine increased fat absorption in SBS. The effect was relatively more pronounced on absorption of the low-absorbable, longer-chained, and saturated fatty acids. The overall gain in absorption of energy was small (6%) because energy absorption from carbohydrates was threefold higher than that from fat. Cholylsarcosine may have cathartic effects on some SBS patients with a colon. The maximal efficacy of cholylsarcosine was reached at a dose of 6 g/day, compared with 12 g/day in three of four patients.
Mixing System for Fracturing Slurries (1990)

ABSTRACT Fracturing operations in Texas and other locations have been improved by (1) mixing fracturing slurries under microprocessor control, (2) applying new baffle and agitator design concepts, and (3) using new methods for achieving rapid material wetting. With these new methods, high sand concentration slurries can be mixed in high-viscosity gels, at low or high rates. A ramped pumping schedule can be used to help achieve greater fracture length since pumping stoppage caused by "sandout" can be delayed or prevented. This paper presents the design and description of the mixing system that makes possible the above-mentioned improvements. and presents case histories of field applications. Proppant schedules and job data are also presented.
Control of Lipase Production by Rhizopus oligosporus under Various Growth Conditions (1988)

Some factors influencing the growth and production of extracellular lipase by Rhizopus oligosporus were studied. Highest yields of enzyme were obtained when Tweens were the carbon source. Soybean meal extract supported good growth and enzyme production. Carbohydrates, vegetable oils, proteins or amino acids did not stimulate lipase production. The fungus grew well with carbohydrate-or protein-supplemented media but not with oils, unless emulsified with a non-metabolizable gum. The production of biomass in static cultures was maximum at 35–40 °C after 4 d at pH 5·5. The yield of lipase was maximum at 25 °C after 3 d at pH 6·5. Shaking cultures enhanced growth but decreased lipase production.
Optically nonlinear waves in thin films (1986)

A new treatment of the behavior of TE nonlinear waves in an optically nonlinear film is given. The new mathematical results are expressed in terms of the physical parameters of the system and represent a straightforward way to introduce the necessary Jacobian elliptic functions. The optical nonlinearity is of the Kerr type and the numerical calculations are performed for a self-focusing medium. Dispersion curves labeled with optical power density at the lower film boundary, detailed plots of the variation of electric field amplitude as the wave number changes, and details of the power distribution across the guide are given. Since two values of a wave number can exist for the same power level and power thresholds exist, the system is of device interest in the area of optical switching.
A Lens into Employee Peer Reviews Via Sentiment-Aspect Modeling (2018)

Given a corpus of employee peer reviews from a large corporation where each review is structured into pros and cons, what are the prevalent traits that employees talk about? How can we describe the performance of an employee with just a few sentences, that help us interpret what their work is praised and criticized for? What is the best way to summarize an employee's reviews, while preserving the content and sentiment as well as possible? In this work, we study a large collection of corporation-wide employee peer reviews from a technology enterprise. Motivated by the challenges we outline in our analysis of employee review data, our work makes two main contributions in the domain of people analytics: (a) Sentiment-Aspect Model (SAM): we introduce a stylized log-linear model that identifies the hidden aspects and sentiment within an employee peer review corpus, (b) Interpretable Sentiment-Aspect Representations (EMPLOYEE2VEC): using SAM, we produce a vector space embedding for each employee, containing an overall sentiment score per aspect, and (c) Summarization of Employee Peer Reviews (PEERSUM): we summarize an employee's peer reviews with just a few sentences which reflect the most prevalent traits and associated sentiment for the employee as much as possible. We show that our model SAM can use the structure present in the dataset as supervision to discover meaningful latent traits and sentiment embodied in the reviews. Our employee vector representations Employee2vecprovide a compact, interpretable overview of their evaluation. The review summaries extracted by PeersUmprovide text that explains the professional performance of an employee in a succinct and objectively quantifiable way. We also show how to use our techniques for people analytics tasks such as the analysis of thematic differences between departments, regions, and genders.
Energy efficient link adaptation using machine learning techniques for wireless OFDM (2016)

Energy Efficiency in wireless communication is very important due to the slow progress in battery technology with improvement in technology. In this paper, we applied energy efficient link adaptation using Machine learning techniques in Orthogonal Frequency Division Multiplexing (OFDM). We sounding the channel condition periodically and observing the channel parameters. Our aim is to select the optimal mode of the channel which maximizes energy efficiency or throughput of data subject to a given quality of service (QoS) constraint. Simulation results show that the proposed solution achieves significant improvement over existing link adaptation algorithms. Presented work aims on maximizing the throughput and provides orders of magnitude gain in energy efficiency linked to poorly chosen fixed modes when used for energy efficiency maximization purposes.
ETM: Entity Topic Models for Mining Documents Associated with Entities (2012)

Topic models, which factor each document into different topics and represent each topic as a distribution of terms, have been widely and successfully used to better understand collections of text documents. However, documents are also associated with further information, such as the set of real-world entities mentioned in them. For example, news articles are usually related to several people, organizations, countries or locations. Since those associated entities carry rich information, it is highly desirable to build more expressive, entity-based topic models, which can capture the term distributions for each topic, each entity, as well as each topic-entity pair. In this paper, we therefore introduce a novel Entity Topic Model (ETM) for documents that are associated with a set of entities. ETM not only models the generative process of a term given its topic and entity information, but also models the correlation of entity term distributions and topic term distributions. A Gibbs sampling-based algorithm is proposed to learn the model. Experiments on real datasets demonstrate the effectiveness of our approach over several state-of-the-art baselines.
Evaluation of new color metrics: guidelines for developing narrow-band red phosphors for WLEDs (2016)

In this review, we summarize the recent findings on novel narrow-band red phosphors, the improved color and visual energy properties of these phosphors, and their ability to improve the optical properties of corresponding warm white pc-WLED lightings.
A low cost automated specific heat capacity meter for liquids (2015)

The amount of heat energy required to change unit mass of a material's temperature by 1°C is called specific heat capacity. Specific heat capacity measurement of liquids can help a lot to select efficient fuel and coolant options for industrial purposes. Here we present the design of a low cost instrument to determine the specific heat capacity of liquids. The system incorporates the use of ATMega 328 micro controller based arduino deumilanove board for accurate and fast measurement. With this system we intend to provide a cost effective and flexible instrument to measure the specific heat capacity of liquids with high degree of accuracy.
Diffuse Lewy body disease: clinical features in 15 cases. (1989)

Fifteen cases of diffuse Lewy body disease were diagnosed on pathological grounds during a single year in one health district. The range and frequency of clinical features contrast strikingly with previous reports. The majority of cases presented with classical levodopa-responsive Parkinson's disease either alone (6 cases) or with mild cognitive impairment (3 cases); the remaining 6 cases presented with cognitive impairment alone. In time almost all patients developed both dementia and Parkinsonism. The dementia was cortical in type, but unusual in that most (12 cases) showed day-to-day fluctuation in severity at some point in their illness. These findings suggest that diffuse Lewy body disease is not rare, and that it presents in a range of ways from dementia with subsequent Parkinsonism to Parkinson's disease with subsequent dementia. The latter mode of presentation suggests that it should be considered as a significant pathological substrate of dementia in Parkinson's disease.
Deployment of a Blockchain-Based Self-Sovereign Identity (2018)

Digital identity is unsolved: after many years of research there is still no trusted communication over the Internet. To provide identity within the context of mutual distrust, this paper presents a blockchain-based digital identity solution. Without depending upon a single trusted third party, the proposed solution achieves passport-level legally valid identity. This solution for making identities Self-Sovereign, builds on a generic provable claim model for which attestations of truth from third parties need to be collected. The claim model is then shown to be both blockchain structure and proof method agnostic. Four different implementations in support of these two claim model properties are shown to offer sub-second performance for claim creation and claim verification. Through the properties of Self-Sovereign Identity, legally valid status and acceptable performance, our solution is considered to be fit for adoption by the general public.
Transfusion‐related acute lung injury: A thrombotic thrombocytopenic purpura treatment‐associated case report and concise review (2008)

Blood products are frequently required immediately prior to, during, or just after an apheresis procedure. Transfusion-related acute lung injury (TRALI) is now the leading cause of transfusion-related mortality, surpassing ABO-incompatible hemolytic reactions. The reported incidence of TRALI varies but is estimated at 1 in 5,000 transfusions. The true incidence could be higher because of under-reporting and under-diagnosis. Plasma is the most frequently implicated blood product. While the pathogenesis of TRALI appears multifactorial, one contributing factor seems to be donor antibodies to cognate recipient neutrophil antigens. Biologically active neutrophil-priming substances may also play a role. New diagnostic criteria have recently been proposed to aid in the diagnosis of TRALI. We report a thrombotic thrombocytopenic purpura (TTP) treatment-associated case of TRALI and review the history, pathogenesis, diagnosis and management of this syndrome. Current risk reduction strategies are also discussed.
Stochastic HPSG Parse Selection using the Redwoods Corpus (2005)

This article details our experiments on HPSG parse disambiguation, based on the Redwoods treebank. Using existing and novel stochastic models, we evaluate the usefulness of different information sources for disambiguation – lexical, syntactic, and semantic. We perform careful comparisons of generative and discrimintative models using equivalent features and show the consistent advantage of discriminatively trained models. Our best system performs at 76% sentence exact march accuracy.
Deposition of Ultrafine Particles in Human Tracheobronchial Airways of Adults and Children (2001)

Inhalation exposure to ultrafine particles, including radon progeny and other combustion aerosols, has been implicated in potential health risks of ambient and indoor environments. These particles deposit in the respiratory tract mainly by diffusion. The purpose of this study was to determine the deposition pattern of nanometer-sized particles in the human tracheobronchial (TB) airways of children and young adults. The deposition was determined for 1.75, 10, and 40 nm 212Pb particles at flow rates corresponding to respiratory minute volumes at rest and during moderate exercise. The 1.75 nm particles were unattached clusters, whereas the 10 and 40 nm particles were silver particles with attached 212Pb clusters. Replicate casts of the upper TB airways of 3, 16, and 23 year old humans were used, including the larynx, trachea, and bronchial airways down to generations 5-8. Deposition in each generation and total deposition were measured by counting the 212Pb gamma photopeak in a NaI (Tl) detector. The effects of airway geometry, particle size, and flow rate on deposition efficiency were studied. The deposition of the 1.75 nm particle, corresponding to unattached indoor radon progeny, was substantially higher than that of the 10 and 40 nm particles. The dependence of particle deposition on the flow rate was relatively weak, and deposition efficiencies were only slightly higher at the lower flow rates. The deposition models for diffusion from parabolic flow underestimated aerosol deposition, whereas the diffusion deposition predicted for plug flow overestimated the TB deposition. The deposition models resulting from this study can be used for developing lung deposition models and in the risk assessment of radon progeny and ultrafine ambient particles.

Visual augmentation for night flight over featureless terrain (1992)

Visual augmentation technique based on infrared cueing lights which project from the aircraft to the terrain is proposed to mitigate the problems associated with night flight over regions with featureless terrains. A series of simulation studies evaluated the effectiveness of several cueing light configurations. Results indicate that certain relatively low-cost cueing light configurations can be effectively used as pseudo-flight directors without impairing the pilot's use of available natural cues in the scene. Pilots prefer configurations which provide multiple samples of the forward terrain. Providing several 'look-aheads' helps to resolve potential vehicle/terrain state ambiguities. It is concluded that cueing lights are capable of creating visual patterns which are readily interpreted and translated to control commands, thus providing pilots with intuitive, low-workload decision aids.
Flexoelectric polarization in hybrid nematic films (2001)

Hybrid films of the nematic liquid crystal penthylcyanobiphenyl (5CB) on the surface of glycerol were studied in the presence of an in-plane electric field. In this geometry there is a macroscopic flexoelectric polarization P(f) with a component in the film plane that couples linearly to the field. Here we report the electric field and film thickness dependence of the width of the 2pi reorientations (2pi walls) in the c director that are trapped by the field and interpret these observations based on continuum elastic theory. We find the difference between the flexoelectric coefficients to be e(1)-e(3)=+11 pC/m.

ATTENUATING THE COAGULATION CASCADE WITH ANNEXIN A5 (2015)

Membrane displayed phosphatidylserine (PS) on platelets, microparticles, endothelial cells and erythrocytes is the platform for the coagulation cascade and annexin A5’s great affinity for PS allows it to bind to it and form a shield that can block the cascade. In spite of this significant anticoagulant ability annexin A5 has no therapeutic anticoagulant application. Why?
Preparation of Flexible Zeolite-Tethering Vegetable Fibers (2001)

A novel approach to assembling monolayers of zeolite-Y crystals on the surfaces of vegetable fibers, such as cotton, hemp, and linen, via covalent linkages is introduced. By polymer linkage the binding strength can be increased to such a degree that well over 90 % of the surface-lining zeolite crystal can endure sonication in toluene for 1 h. The Figure shows an SEM image of zeolite-Y crystals attached to the surface of cotton fibers.
Reactor-scale models for rf diode sputtering of metal thin films (1999)

This article describes the development of an integrated physical model for the rf diode sputtering of metal thin films. The model consists of: (1) a computational fluid dynamic finite element model for the velocity and pressure distribution of the working gas Ar flow in the chamber, (2) a steady-state plasma model for the flux and energy of Ar ions striking the target and the substrate, (3) a molecular dynamics sputtering model for the energy distribution, angle distribution, and yield of the sputtered atoms (Cu) from the target, and (4) a direct simulation Monte Carlo (DSMC) model for the transport of Cu atoms through the low-pressure argon gas to the deposition substrate. The individual models for gas flow, plasma discharge, Cu sputtering, and DSMC-based Cu atom transport are then integrated to create a detailed, steady-state, input–output model capable of predicting thin-film deposition rate and uniformity as a function of the process input variables: power, pressure, gas temperature, and electrode spacing. Deposition rate and uniformity in turn define the characteristics of thin films exploited in applications, for example, the saturation magnetic field for a giant magnetoresistive multilayer. This article also describes the development of an approximate input–output model whose CPU time is several orders-of-magnitude faster than that of the detailed model. Both models were refined and validated against experimental data obtained from rf diode sputtering experiments.

Designing The Built-In Microcontroller Control Systems of Executive Robotic Devices Using The Digital Twins Technology (2019)

The article presents approaches to the development of robotic systems based on the use of virtual prototypes, known as digital twins. Also, usage of such systems for walking robotic mechanisms are demonstrated by the example of developing an experimental debugging platform that supports both the design of algorithms for robot behavior at the upper level of the control hierarchy and the design of control algorithms for its nodes at the lower level. Authors used different basic tooling systems integrated with each other through cross-platform tools, such as Gazebo, V-Rep, IAR Embedded Workbench, Quartus, Fuzzy51 and several others.
C–H bond cleavage-enabled aerobic ring-opening reaction of <i>in situ</i> formed 2-aminobenzofuran-3(2<i>H</i>)-ones (2021)

A C-H bond cleavage-enabled aerobic ring-opening reaction of 2-aminobenzofuran-3(2<i>H</i>)-ones formed <i>in situ</i> by hemiacetals with a variety of amines is reported. This simple one-pot reaction provides an alternative approach to obtain <i>o</i>-hydroxyaryl glyoxylamides in excellent yields of up to 97%. Alkylamines react with hemiacetals <i>via</i> a catalyst-free dehydration condensation to generate 2-aminobenzofuran-3(2<i>H</i>)-ones. The <i>in situ</i> formed semicyclic <i>N</i>,<i>O</i>-acetals undergo the same amine-initiated C-H bond hydroxylation in air under mild conditions to afford ring-opening products. Similarly, arylamines were investigated as substrates for a two-step tandem process involving a DPP-catalyzed condensation followed by a Et<sub>2</sub>NH-mediated C-H hydroxylation. Unlike the previously reported functionalization of <i>N</i>,<i>O</i>-acetals <i>via</i> a C-O or C-N cleavage, the aerobic oxidative C-H hydroxylation in this reaction, which is promoted by using stoichiometric amounts of alkylamines as both a Lewis base and a reductant at room temperature under atmospheric air, proceeds <i>via</i> α-carbonyl-stabilized carbanion intermediates from the C-H cleavage of <i>N</i>,<i>O</i>-acetals.
Single-Walled Carbon Nanotube-Based Chemiresistive Affinity Biosensors for Small Molecules: Ultrasensitive Glucose Detection (2010)

We report for the first time single-walled carbon nanotube (SWNT)-based chemiresistive affinity sensors for highly sensitive and selective detection of small and/or weakly charged or uncharged molecules using a displacement format. The detection of glucose, a small, weakly charged molecule, by displacement of plant lectin (concavalin A) bound to a polysaccharide (dextran) immobilized on SWNTs with picomolar sensitivity and selectivity over other sugars and human serum proteins is demonstrated as a proof of concept.
Influence of strain relaxation of the AlxGa1−xN barrier on transport properties of the two-dimensional electron gas in modulation-doped AlxGa1−xN/GaN heterostructures (2000)

Influences of the thickness of the Si-doped n-type Al0.22Ga0.78N barrier and the thickness of the Al0.22Ga0.78N spacer on mobility and density of the two dimensional electron gas (2DEG) in modulation-doped Al0.22Ga0.78N/GaN heterostructures were investigated. 2DEG mobilities of 1274 cm2/V s at 300 K and 4495 cm2/V s at 77 K were reached. Both 2DEG mobility and density decrease dramatically when the Al0.22Ga0.78N barrier becomes partially relaxed, indicating that transport properties of the 2DEG are influenced significantly by the piezoelectric polarization of the Al0.22Ga0.78N layer. From our results, the critical thickness of an Al0.22Ga0.78N layer on GaN is estimated to be between 65 and 75 nm, which is much higher than that predicted by theoretical calculation. This may be attributed to the interaction of misfit dislocations and the presence of a high density of extended defects in the Al0.22Ga0.78N layer.
