Comparative evaluation of the efficacy of four topical medications individually or in combination to treat grade I acne vulgaris. (2009)

A randomised study was carried out to evaluate the efficacy of four topical medications individually and in combination to treat grade I acne vulgaris which is characterised by mild lesions (< 10 in one side of face) consisting of predominantly comedones with occasional pustules in oily skin. Maintaining the inclusion and exclusion criteria 100 patients were selected and divided into 5 groups to receive different topical drugs at random basis in the dermatology OPD. Topical medication given to them is mentioned below against each group: Group I--retinonic acid, group II--benzoyl peroxide, group III--clindamycin, group IV--cleanser and group V--all the four medications. The patients were observed for reduction in number of comedones, suppression of papulopustules with healing rate, effects on facial skin, and rate of recurrence. Results were observed according to the groups. In group I old acne was reduced in size and gradually cleared off (80%). Recurrence was few with appearance of new microcomedones which were cleared off within short time. Skin became smoother and fresh. Texture became lighter in colour. In group II whiteheads were reduced at about 70% in number. Rate of recurrence was normal. Skin became rough and dry. In group III pustular acne healed better and faster. In group IV acne of oily skin healed better and faster. Rate of recurrence was normal. Skin became fresh and oil-free. In group V reduction of lesions was very much significant (90%) with quick healing rate of the comedones. Recurrence was normal but delayed. Skin became smoother, finer and fresher. So, combination therapy is better. Cleanser is always helpful even without medications.
Deep Learning With Edge Computing: A Review (2019)

Deep learning is currently widely used in a variety of applications, including computer vision and natural language processing. End devices, such as smartphones and Internet-of-Things sensors, are generating data that need to be analyzed in real time using deep learning or used to train deep learning models. However, deep learning inference and training require substantial computation resources to run quickly. Edge computing, where a fine mesh of compute nodes are placed close to end devices, is a viable way to meet the high computation and low-latency requirements of deep learning on edge devices and also provides additional benefits in terms of privacy, bandwidth efficiency, and scalability. This paper aims to provide a comprehensive review of the current state of the art at the intersection of deep learning and edge computing. Specifically, it will provide an overview of applications where deep learning is used at the network edge, discuss various approaches for quickly executing deep learning inference across a combination of end devices, edge servers, and the cloud, and describe the methods for training deep learning models across multiple edge devices. It will also discuss open challenges in terms of systems performance, network technologies and management, benchmarks, and privacy. The reader will take away the following concepts from this paper: understanding scenarios where deep learning at the network edge can be useful, understanding common techniques for speeding up deep learning inference and performing distributed training on edge devices, and understanding recent trends and opportunities.

A third-generation 1.1 GHz 64b microprocessor provides 1 MB on-chip L2$, 4GB/s off chip memory bandwidth and a 200MHz JBUS interface that supports 1 to 4 processors. The 90M transistor chip is implemented in a 7-level metal copper 0.13/spl mu/m CMOS process and dissipates 53W at 1.3V and 1.1GHz.
Circadian control of pain and neuroinflammation (2017)

The importance of a neuroinflammatory response to the development and maintenance of inflammatory and neuropathic pain have been highlighted in recent years. Inflammatory cells contributing to this response include circulating immune cells such as monocytes, T and B lymphocytes, and neutrophils, as well as microglia in the central nervous system. Pain signals are transmitted via sensory neurons in the peripheral nervous system, which express various receptors and channels that respond to mediators secreted from these inflammatory cells. Chronobiological rhythms, which include the 24-hr circadian cycle, have recently been shown to regulate both nervous and immune cell activity and function. This review examines the current literature on chronobiological control of neuroinflammatory processes, with a focus on inflammatory and neuropathic pain states. While the majority of this work has stemmed from observational studies in humans, recent advances in using animal models have highlighted distinct mechanisms underlying these interactions. Better understanding interactions between the circadian and neuroimmune systems can help guide the development of new treatments and provide improved care for patients suffering from acute and chronic pain.
The Use of an Optical Power Combiner for Multiplexing Multiple Television Sources in Single-Fiber Optical Systems (1979)

A theoretical analysis is made of the maximum allowable transmission loss for frequency division multiplexed optical transmission of TV signals using an optical power combiner and intensity modulated multiple light sources. A PIN photodiode detector is assumed and the performance of a configuration using multiple light sources and an optical power combiner is compared to the performance of an electronic power combiner with a single light source. The results show that the maximum allowable transmission loss for 10 TV channels is greater than 25 dB if the modulation factor is 0.8 and the power supplied to the power combiner is 3 mW per light source. Practical optical fiber transmission systems carrying 10 TV channels over distances greater than 5 km therefore appear possible in the not-too-distant future if optical fiber cable with a loss of 5 dB/km is used.
Urea Transporter UT3 Functions as an Efficient Water Channel (1998)

A family of molecular urea transporters (UTs) has been identified whose members appear to have an exceptionally high transport turnover rate. To test the hypothesis that urea transport involves passage through an aqueous channel, osmotic water permeability was measured in Xenopus oocytes expressing UTs. The UT3 class of urea transporters functioned as efficient water channels. Quantitative measurement of single channel water permeability (pf) using epitope-tagged rat UTs gave pf (in cm3/s x 10(-14)) of 0.14 +/- 0.11 (UT2) and 1.4 +/- 0.2 (UT3), compared with 6.0 and 2.3 for water channels AQP1 and AQP3, respectively. Relative single channel urea permeabilities (purea) were 1.0 (UT2), 0.44 (UT3), and 0.0 (AQP1). UT3-mediated water and urea transport were weakly temperature-dependent (activation energy <4 kcal/mol), inhibited > 75% by the urea transport inhibitor 1,3-dimethylthiourea, but not inhibited by the water transport inhibitor HgCl2. To test for a common water/urea pore, the urea reflection coefficient (sigmaurea) was measured by independent induced osmosis and solvent drag methods. In UT3-expressing oocytes, the time course of oocyte volume in response to different urea gradients (induced osmosis) gave sigmaurea approximately 0.3 for the UT3 pathway, in agreement with sigmaurea determined by the increase in uptake of [14C]urea during osmotic gradient-induced oocyte swelling (solvent drag). In oocytes of comparable water and urea permeability coexpressing AQP1 (permeable to water, not urea) and UT2 (permeable to urea, not water), sigmaurea = 1. These results indicate that UT3 functions as a urea/water channel utilizing a common aqueous pathway. The water transporting function and low urea reflection coefficient of UT3 in vasa recta may be important for the formation of a concentrated urine by countercurrent exchange in the kidney.
Scalable RF MEMS Switch Matrices: Methodology and Design (2009)

This paper proposes new solutions for implementing wideband large switch matrices. These solutions are based on crossbar and L-shaped topologies. This paper introduces a high-performance wideband switch cell to build up scalable NtimesN switch matrices and gives an account of the design, fabrication, and characteristics of the switch cell and a 3times3 crossbar switch matrix. The chosen design procedure is seen to be appropriate since it produces valid measured results. In addition, this paper presents an RF microelectromechanical systems L-shaped switch matrix, which indicates less variation of characteristics for certain types of connectivity. It also demonstrates that for a 4times4 switch matrix, there is a 50% improvement in insertion loss and phase-shift variation.

Synthesis of uniformly distributed carbon nanotubes on a large area of Si substrates by thermal chemical vapor deposition (1999)

We have synthesized carbon nanotubes by thermal chemical vapor deposition of C2H2 on transition metal-coated silicon substrates. Multiwalled carbon nanotubes are uniformly synthesized on a large area of the plain Si substrates, different from previously reported porous Si substrates. It is observed that surface modification of transition metals deposited on substrates by either etching with dipping in a HF solution and/or NH3 pretreatment is a crucial step for the nanotube growth prior to the reaction of C2H2 gas. We will demonstrate that the diameters of carbon nanotubes can be controlled by applying the different transition metals.
Hydrothermal Formation of Hydroxyapatite Layers on the Surface of Type‐A Zeolite (2004)

Type‐A zeolite evenly covered with hydroxyapatite thin layers was prepared using hydrothermal treatment at 120°C for 8 h under autogenous pressure. The hydroxyapatite needlelike nanocrystals, 100–200 nm in diameter and 30 nm in thickness, were grown under the reaction between discharged Ca 2+ ions from type‐A zeolite and PO 4 3− ions in (NH 4 ) 3 PO 4 solution. The preferential orientations of the c ‐axis of hydroxyapatite crystals perpendicular to a zeolite surface were observed using transmission electron microscopy. The crystal structure of type‐A zeolite was not destroyed under the reaction, but the surface morphology was changed only with complete covering of scaly hydroxyapatite particles.
Cholesteryl ester hydrolase activity is abolished in HSL macrophages but unchanged in macrophages lacking KIAA1363 (2010)

Cholesteryl ester (CE) accumulation in macrophages represents a crucial event during foam cell formation, a hallmark of atherogenesis. Here we investigated the role of two previously described CE hydrolases, hormone-sensitive lipase (HSL) and KIAA1363, in macrophage CE hydrolysis. HSL and KIAA1363 exhibited marked differences in their abilities to hydrolyze CE, triacylglycerol (TG), diacylglycerol (DG), and 2-acetyl monoalkylglycerol ether (AcMAGE), a precursor for biosynthesis of platelet-activating factor (PAF). HSL efficiently cleaved all four substrates, whereas KIAA1363 hydrolyzed only AcMAGE. This contradicts previous studies suggesting that KIAA1363 is a neutral CE hydrolase. Macrophages of KIAA1363(-/-) and wild-type mice exhibited identical neutral CE hydrolase activity, which was almost abolished in tissues and macrophages of HSL(-/-) mice. Conversely, AcMAGE hydrolase activity was diminished in macrophages and some tissues of KIAA1363(-/-) but unchanged in HSL(-/-) mice. CE turnover was unaffected in macrophages lacking KIAA1363 and HSL, whereas cAMP-dependent cholesterol efflux was influenced by HSL but not by KIAA1363. Despite decreased CE hydrolase activities, HSL(-/-) macrophages exhibited CE accumulation similar to wild-type (WT) macrophages. We conclude that additional enzymes must exist that cooperate with HSL to regulate CE levels in macrophages. KIAA1363 affects AcMAGE hydrolase activity but is of minor importance as a direct CE hydrolase in macrophages.
A new guided-wave lens structure (1990)

A guided-wave lens is reported. The present lens structure is realized by embedding a low-index lens-shaped waveguide region in a surrounding higher-index planar waveguide. Very large index differences between the lens region and host waveguide are realizable using this technique, making it possible to fabricate low f-number lenses with low spherical aberration. The lens exhibits excellent off-axis performance, low chromatic aberration, and high polarization independence. A prototype f/2 lens in a GaAs/Ga/sub 0.97/Al/sub 0.03/As waveguide has been designed and fabricated using Corning 7059 glass and SiO/sub 2/ for the lens waveguide structure.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A covariance fitting approach for correlated acoustic source mapping (2010)

Microphone arrays are commonly used for noise source localization and power estimation in aeroacoustic measurements. The delay-and-sum (DAS) beamformer, which is the most widely used beamforming algorithm in practice, suffers from low resolution and high sidelobe level problems. Therefore, deconvolution approaches, such as the deconvolution approach for the mapping of acoustic sources (DAMAS), are often used for extracting the actual source powers from the contaminated DAS results. However, most deconvolution approaches assume that the sources are uncorrelated. Although deconvolution algorithms that can deal with correlated sources, such as DAMAS for correlated sources, do exist, these algorithms are computationally impractical even for small scanning grid sizes. This paper presents a covariance fitting approach for the mapping of acoustic correlated sources (MACS), which can work with uncorrelated, partially correlated or even coherent sources with a reasonably low computational complexity. MACS minimizes a quadratic cost function in a cyclic manner by making use of convex optimization and sparsity, and is guaranteed to converge at least locally. Simulations and experimental data acquired at the University of Florida Aeroacoustic Flow Facility with a 63-element logarithmic spiral microphone array in the absence of flow are used to demonstrate the performance of MACS.
Neurologic Disorders (2010)

Urosepsis was a common almost invariably fatal problem in the early years of catheterization usage. The introduction of antiseptics, beginning with Lister, followed by the use of antibiotic therapies decreased mortality associated with this therapy and provided better outcomes overall. In 1966, the Stoke Mandeville National Spinal Injuries Center introduced sterile technique for catheterization which provided more options for people requiring catheterizations (1) . Shortly after the sterile technique introduction, Lapides pioneered the clean intermittent self-catheterization (CISC) technique after one of his patients reused a catheter that had been dropped, without resterilization, without untoward consequences to the patient’s bladder system.

Predictive driving strategies under urban conditions for reducing fuel consumption based on vehicle environment information (2011)

This brief deals with the improvement of a vehicle's pass-through of predictively known urban driving situations concerning its fuel consumption. Today's technology enables the prediction of information about traffic events. This information can be used to identify efficient driving strategies. The main aim is to reduce the dynamics in the velocity profiles of driving situations and with it the corresponding fuel consumption in urban traffic. An algorithm has been built to calculate fuel consumption optimized driving trajectories. Input parameters are temporal and spatial depending constraints of the driving situation as well as other restrictions like a speed-limit. The main objective of the function was to enable a situation adaptive reaction to every predictively known forthcoming traffic event. Thus an optimized driving trajectory can be steadily calculated for the next route section of the vehicle provided that predictive information about the traffic events are available. The higher the availability of information the better an optimization of the driving strategies will be possible. Fuel characteristics and other energetically relevant data for a real-world vehicle have been created by detailed simulation to evaluate the fuel consumption of the driving strategies. For demonstration purposes the common driving situation ”traffic light” was chosen. The fuel consumption calculated for the predictive driving strategies is compared to the consumption of a simulated average driver without predictive information. The calculated potentials have been verified by measuring the fuel consumption of an experimental vehicle for the simulated driving strategies.
Impact of Elevated Carbon Dioxide on Primary, Secondary Metabolites and Antioxidant Responses of Eleais guineensis Jacq. (Oil Palm) Seedlings (2012)

A split plot 3 by 3 experiment was designed to investigate the relationships among production of primary metabolites (soluble sugar and starch), secondary metabolites (total flavonoids, TF; total phenolics, TP), phenylalanine lyase (PAL) activity (EC 4.3.1.5), protein and antioxidant activity (FRAP) of three progenies of oil palm seedlings, namely Deli AVROS, Deli Yangambi and Deli URT, under three levels of CO₂ enrichment (400, 800 and 1,200 μmol·mol⁻¹) for 15 weeks of exposure. During the study, the treatment effects were solely contributed by CO₂ enrichment levels; no progenies and interaction effects were observed. As CO₂ levels increased from 400 to 1,200 μmol·mol⁻¹, the production of carbohydrate increased steadily, especially for starch more than soluble sugar. The production of total flavonoids and phenolics contents, were the highest under 1,200 and lowest at 400 μmol·mol⁻¹. It was found that PAL activity was peaked under 1,200 μmol·mol⁻¹ followed by 800 μmol·mol⁻¹ and 400 μmol·mol⁻¹. However, soluble protein was highest under 400 μmol·mol⁻¹ and lowest under 1,200 μmol·mol⁻¹. The sucrose/starch ratio, i.e., the indication of sucrose phosphate synthase actvity (EC 2.4.1.14) was found to be lowest as CO₂ concentration increased from 400 > 800 > 1,200 μmol·mol⁻¹. The antioxidant activity, as determined by the ferric reducing/antioxidant potential (FRAP) activity, increased with increasing CO₂ levels, and was significantly lower than vitamin C and α-tocopherol but higher than butylated hydroxytoluene (BHT). Correlation analysis revealed that nitrogen has a significant negative correlation with carbohydrate, secondary metabolites and FRAP activity indicating up-regulation of production of carbohydrate, secondary metabolites and antioxidant activity of oil palm seedling under elevated CO₂ was due to reduction in nitrogen content in oil palm seedling expose to high CO₂ levels.
A battery-less WiFi-BER modulated data transmitter with ambient radio-wave energy harvesting (2011)

We have developed a new battery-less bit-error-rate modulated (BERM) data transmission technology that can directly send data to a WiFi-equipped PC without affecting WiFi communication on the PC. BER modulated data at a 5.5kbps data-rate has been successfully transmitted at a 30-cm distance between a test chip and measurement equipment. The chip also has an energy harvesting function with an active ambient-radio power searching (AAPS) architecture that enhances harvest efficiency. Harvested power was 30.8µW at a 30cm-distance from a 250mW (24dBm) emission WiFi access point (AP), and the operational frequency had a very wide range, 1.9 to 2.4GHz.

Axial Turbine Blade Tips: Function, Design, and Durability (2006)

An overview of the science and technology involved in today's turbine engines is presented with specific focus on the critical rotational-to-stationary interfaces comprising axial turbine blade tips. The purpose is to provide a concise informative review of turbine blade tip functional, design, and durability issues. Neither a historical account nor a bibliography is presented. Attention is paid primarily to the most challenging blade tips in high-pressure, high-temperature gas turbine systems, although most of the science discussed applies equally well to blade tips in low-pressure turbines, as well as steam turbines. As such, a wide range of both aircraft engine and power generating turbine systems are considered. Basic functional requirements, turbine systems design aspects, and transient operational considerations affecting blade tips and affected by blade tips are discussed in light of the multidisciplinary tradeoffs involved in a successful design. The three dominant design philosophies for blade tips in practice today are presented with detailed examination of the aerodynamics, heat transfer, and cooling benefits and detractors. Finally, the in-service durability aspects of turbine blade tips are noted.
