6H-SiC pressure sensor operation at 600°C (2002)

Experimental results of batch-microfabricated 6H-SiC piezoresistive pressure sensors operational between room temperature to 600/spl deg/C are reported. For a diaphragm thickness of 30 /spl mu/m, the typical room temperature full-scale output for maximum pressure of 1000 psi was 66.41 mV, with a hysteresis and nonlinearity of less than 1%FSO across the range of operating temperature. For a diaphragm thickness of 40 /spl mu/m, the typical room temperature full-scale output for maximum pressure of 1000 psi was between 39 mV and 42 mV, also with a hysteresis and nonlinearity of less than 1% across the range of operating temperature. The temperature coefficient of resistance (TCR) had negative values from room temperature to 350/spl deg/C due to the gradual drop in input resistance. The temperature coefficient of gauge factor (TCGF) averaged about -0.14%//spl deg/C from room temperature to 600/spl deg/C. These values obtained were consistent with the characteristics of 6H-SiC epilayer having an impurity concentration of 2/spl times/10/sup 19/ cm/sup -3/.
Microwave power amplifiers with digitally-controlled power supply voltage for high efficiency and high linearity (2002)

A power amplifier architecture is presented which comprises a basic amplifier with an efficient, high modulation bandwidth DC-DC converter. The amplifier and the DC-DC converter are controlled by a digital signal processor that provides input signal pre-distortion, supply voltage optimization and equalization. Experimental results at 950 MHz showed ACPR values acceptable for IS-95 CDMA handset applications. With variable power supply, the overall efficiency improved by a factor of 1.4/spl times/ (when averaged over representative conditions of usage).
Mitotic Count and Estimation of the Risk of GIST Recurrence in Patients Treated with Preoperative Imatinib (2019)

Preoperative imatinib is used frequently in the treatment of large localized GISTs to shrink the tumor prior to surgery. This approach may lead to challenges in the estimation of the risk of recurrence and the need of adjuvant imatinib, because the diagnosis is usually made from a needle biopsy with scant tissue for the assessment of GIST mitotic activity, a key prognostic factor. We propose a mitosis count multiplication method as a proxy for estimating the tumor mitotic count in select cases.
Fuzzy logic based sentiment analysis of product review documents (2014)

Sentiment Analysis is the process of determining subjectivity, polarity and polarity strength of a piece of text. Survey shows that 81% of Internet users have done on-line research on a product at least once. Manual analysis of this reviews is difficult. To mine the overall sentiment or opinion polarity, sentiment analysis can be used to mine the overall sentiment or opinion polarity of the review. The objective of this paper is to extract features from the product reviews and classify reviews into positive, negative and neutral. Feature based sentiment classification approach is used to extract sentiments. It involves preprocessing to remove noise, extraction of features and corresponding descriptors and tagging their polarity. The proposed technique extends the feature based classification approach to incorporate the effect of various linguistic hedges. This approach uses fuzzy functions to emulate the effect of modifiers, concentrators and dilators. The system was evaluated with SFU corpus and the results suggest that sentiment analysis using fuzzy logic performs remarkably well.
Chromatin association and DNA binding properties of the c-<i>fos</i>proto-oncogene product (1987)

As a first step in the analysis of the molecular function of the nuclear c-fos proto-oncogene product we have studied its subnuclear localization in serum-stimulated mouse fibroblasts where it forms a non-covalent, apparently monodisperse complex with another nuclear protein, p39. The c-fos/p39 complex is almost quantitatively released from intact nuclei by DNasel or micrococcus nuclease treatment under conditions where only a minor fraction of DNA and nuclear proteins is released. In gel filtration experiments, c-fos/p39 comigrates with chromatin and seems to be associated with regions of increased DNasel accessibility. c-fos/p39 is bound to chromatin by electrostatic forces of moderate strength since greater than 90% of the complex can be eluted from nuclei at 0.4 M NaCl. In vitro, the c-fos/p39 complex in nuclear extracts binds to double- and single-stranded calf thymus DNA, suggesting that the association of c-fos/p39 with chromatin is at least in part due to its interaction with DNA. In agreement with this conclusion, c-fos/p39 is released from nuclei by incubation with tRNA, presumably due to competition for binding sites. Our observations are compatible with the hypothesis that c-fos may play a role in the regulation of gene expression.
Tails of Lipschitz Triangular Flows (2020)

We investigate the ability of popular flow based methods to capture tail-properties of a target density by studying the increasing triangular maps used in these flow methods acting on a tractable source density. We show that the density quantile functions of the source and target density provide a precise characterization of the slope of transformation required to capture tails in a target density. We further show that any Lipschitz-continuous transport map acting on a source density will result in a density with similar tail properties as the source, highlighting the trade-off between a complex source density and a sufficiently expressive transformation to capture desirable properties of a target density. Subsequently, we illustrate that flow models like Real-NVP, MAF, and Glow as implemented originally lack the ability to capture a distribution with non-Gaussian tails. We circumvent this problem by proposing tail-adaptive flows consisting of a source distribution that can be learned simultaneously with the triangular map to capture tail-properties of a target density. We perform several synthetic and real-world experiments to compliment our theoretical findings.
Partial lipodystrophy and insulin resistant diabetes in a patient with a homozygous nonsense mutation in <i>CIDEC</i> (2009)

Lipodystrophic syndromes are characterized by adipose tissue deficiency. Although rare, they are of considerable interest as they, like obesity, typically lead to ectopic lipid accumulation, dyslipidaemia and insulin resistant diabetes. In this paper we describe a female patient with partial lipodystrophy (affecting limb, femorogluteal and subcutaneous abdominal fat), white adipocytes with multiloculated lipid droplets and insulin-resistant diabetes, who was found to be homozygous for a premature truncation mutation in the lipid droplet protein cell death-inducing Dffa-like effector C (CIDEC) (E186X). The truncation disrupts the highly conserved CIDE-C domain and the mutant protein is mistargeted and fails to increase the lipid droplet size in transfected cells. In mice, Cidec deficiency also reduces fat mass and induces the formation of white adipocytes with multilocular lipid droplets, but in contrast to our patient, Cidec null mice are protected against diet-induced obesity and insulin resistance. In addition to describing a novel autosomal recessive form of familial partial lipodystrophy, these observations also suggest that CIDEC is required for unilocular lipid droplet formation and optimal energy storage in human fat.
Analysis of Flip Ambiguities for Robust Sensor Network Localization (2010)

Erroneous local geometric realizations in some parts of a network due to the sensitivity to certain distance-measurement errors with respect to some neighboring sensor locations is a major problem in wireless sensor-network localization, which may, in turn, affect the reliability of the localization of the whole or a major portion of the sensor network. This phenomenon is well described using the notion of ¿flip ambiguity¿ in rigid graph theory. In this paper, we present a formal geometric analysis of flip-ambiguity problems in planar sensor networks via quantification of the likelihood of flip ambiguities in arbitrary sensor neighborhood geometries. Based on this analysis, we establish a robustness criterion to detect flip ambiguities in such neighborhood geometries. In addition to the analysis, the established robustness criterion is embedded in localization algorithms to enhance the reliability of the produced location estimates by eliminating neighborhoods with flip ambiguities from being included in the localization process.
An apparatus for the evaluation of web heating technologies: development, capabilities, preliminary results, and potential uses (1996)

It is generally acknowledged that web preheating improves press performance by lowering the viscosity of the water internal to the web. Improvements in web preheating translate into immediate improvements in press efficiency. Steam boxes are the universally accepted devices for preheating the web. However, there is little or no accessible literature on how best to use steam boxes. The Institute of Paper Science and Technology has designed, built, and tested an apparatus for evaluating web-heating technologies. The apparatus can be used to investigate both web-heating problems on specific paper machines and fundamental processes in web heating.
Plane-sweep algorithms for intersecting geometric figures (1982)

Algorithms in computational geometry are of increasing importace in computer-aided design, for example, in the layout of integrated circuits. The efficient computation of the intersection of several superimposed figures is a basic problem. We consider plane figures defined by points connected by straight line segments, for example, polygons (not necessarily simple) and maps (embedded planar graphs). The regions into which the plane is partitioned by these intersecting figures are to be processed in various ways such as listing the boundary of each region in cyclic order or sweeping the interior of each region. Let n be the total number of points of all the figures involved and s be the total number of intersections of all line segments. We present two planesweep algorithms that solve the problems above; in the general case (no convexity) in time O((n + s)log n) and space O(n + s); when the regions of each given figure are convex, the same can be achieved in time O(n log n + s) and space O(n).
Winter Populations of Some Diabrotica1 in Central Mexico: Voltinism and Pheromone Response (1978)

Adult Diabrotica virgifera LeConte were not found in the winter in areas of subtropical Mexico where they are abundant in the summer. Eggs of the subtropical population of this species were found to be in diapause in Feb. The study confirms that the subtropical population is univoltine, that the winter is spent in the egg in diapause, and that this diapause is more intense than that of populations of D. virgifera in temperate climates. Large populations of D. undecimpuncata were found in Feb. in the state of Guanajuato as were large populations of D. balteata LeConte in the states of Guanajuato and Morelos. Males of D. balteata were not attracted to the pheromones of either D. virgifera or D. undecimpunctata nor were males of D. undecimpunctata attracted to the pheromone of D. virgifera. However, pheromone obtained from a laboratory strain of South Dakota D. undecimpunctata was attractive to males of the Mexican population of this species.
Evaluation of the RC4 Algorithm for Data Encryption. (2006)

Analysis of the effect of different parameters of the RC4 encryption algorithm where examined. Some experimental work was performed to illustrate the performance of this algorithm based on changing some of these parameters. The execution time as a function of the encryption key length and the file size was examined; this has been stated as complexity and security. Various data types were analyzed and the role of the data type was also emphasized. The results have been analyzed and interpreted as mathematical equations showing the relationship between the examined data and hence can be used to predict any future performance of the algorithm under different conditions. The order of the polynomial to approximate the execution time was justified.
MPaySmart: A Customer Centric Approach in Offering Efficient Mobile Payment Services (2008)

New advances in mobile computer technology, along with rapid growth of quality and quantity of wireless networks, introduce new capabilities, applications, and concerns to computer science and industry. Mobile payment, in which mobile customers use their phones for performing financial transactions, is a promising and exciting domain that has been rapidly developing recently. Although different mobile payment schemes has been designed and deployed worldwide, there is still a lack of research in achieving efficient and global mobile payment systems. Different business players and various technologies make the situation more complex. In this paper, we present MPaySmart, a secure and user-friendly mobile payment system which focuses on customer requirements. It is an operator-driven SIM-based mobile payment scheme, which utilizes Over-the-Air technology for secure communications.
Selective Transport of Alkali Metal Cations in Solvent Extraction by Proton-Ionizable Dibenzocrown Ethers (1992)

Abstract Lipophilic crown ethers with pendant proton-ionizable groups are novel metal complexing agents for use in solvent extraction of alkali metal cations. A variety of dibenzocrown ether carboxylic acids and dibenzo crown phosphonic acid monoesters have been examined to probe the effect of structural variation within the complexing agent upon selectivity and efficiency in solvent extraction. Results from competitive solvent extractions of alkali metal cations from aqueous solutions into chloroform are summarized.
Promiscuous drugs compared to selective drugs (promiscuity can be a virtue) (2005)

We contend that an ideal drug may be one whose efficacy is based not on the inhibition of a single target, but rather on the rebalancing of the several proteins or events, that contribute to the etiology, pathogeneses, and progression of diseases, i.e., in effect a promiscuous drug. Ideally, if this could be done at minimum drug concentration, side effects could be minimized. Corollaries to this argument are that the growing fervor for researching truly selective drugs may be imprudent when considering the totality of responses; and that the expensive screening techniques used to discover these, may be both medically and financially inefficient.
Non-destructive Testing Robots (NDTBOTs) for In-Service Storage Tank Inspection (2018)

Petrochemical storage tanks are generally inspected when the tank is offline mostly to assess the extent of underside corrosion on the tank floor. Emptying, cleaning and opening a tank for inspection takes many months and is very expensive. Inspection costs can be reduced significantly by inserting robots through manholes on the tank roof to perform non-destructive testing. The challenge is to develop robots that can operate safely in explosive and hazardous environments and measure the thickness of floor plates using ultrasound sensors. This paper reports on the development of a small and inexpensive prototype robot (NDTBOT) which is designed to be intrinsically safe for zone zero operation. The robot “hops” across the floor to make measurements, without any external moving parts. The paper describes the design, experimental testing of the NDTBOT and presents results of steel plate thickness measurements made under water.
Bluish‐green semipolar GaInN/GaN light emitting diodes on {1$ \bar 1 $01} GaN side facets (2008)

Abstract Bluish‐green semipolar GaInN/GaN light emitting diodes were realized on the {1 $ \bar 1 $ 01} side facets of selectively grown GaN stripes with an on‐wafer optical output power of 240 mW@20mA for about 500 nm emission wavelength. Structural investigations using TEM, SEM, HRXRD and AFM could be related to the luminescence properties in PL and CL. The defect‐related luminescence peaks at 3.3 eV and 3.41 eV, typically observed in non‐ and semipolar GaN, could be eliminated in our facet LEDs by optimized growth conditions. Furthermore, a 50% higher indium incorporation for these {1 $ \bar 1 $ 01} facets compared to c ‐plane growth is found, what helps significantly to achieve longer wavelength emission in spite of the reduced Quantum Confined Stark Effect.

3D Reconstruction from Accidental Motion (2014)

We have discovered that 3D reconstruction can be achieved from asingle still photographic capture due to accidental motions of thephotographer, even while attempting to hold the camera still. Although these motions result in little baseline and therefore high depth uncertainty, in theory, we can combine many such measurements over the duration of the capture process (a few seconds) to achieve usable depth estimates. Wepresent a novel 3D reconstruction system tailored for this problemthat produces depth maps from short video sequences from standard cameraswithout the need for multi-lens optics, active sensors, or intentionalmotions by the photographer. This result leads to the possibilitythat depth maps of sufficient quality for RGB-D photography applications likeperspective change, simulated aperture, and object segmentation, cancome "for free" for a significant fraction of still photographsunder reasonable conditions.
Growth of α‐AI <sub>2</sub> O <sub>3</sub> Platelets in the HF‐γy‐AI <sub>2</sub> O <sub>3</sub> System (1994)

In the presence of a fluorine mineralizer, highly aggregated, &lt;5 μm α‐Al 2 O 3 platelet particles form by vapor transport during the thermal transformation of γ‐alumina. Platelet aggregation was determined to occur by platelet inter‐growth and by edge nucleation on primary α‐Al 2 0 3 platelets. The addition of 10 10 α‐alumina seed particles/cm 3 γ–Al 2 O 3 resulted in the development of discrete particles during the initial stage of transformation. Impingement of the growing platelets during the latter stage of transformation, however, resulted in intergrowth, a process which was not changed by seeding. Particle size distribution broadening was observed to increase with increasing HF and H 2 O concentrations because vapor reactant supersaturation increases the degree of edge nucleation. When initially low HF and H 2 O concentrations were used in seeded systems, however, essentially aggregate‐free α‐Al 2 O 3 platelets of 10–15 μm were obtained.
Absence of Adverse Effects in Cynomolgus Macaques Treated with CNTO 95, a Fully Human Anti-αv Integrin Monoclonal Antibody, Despite Widespread Tissue Binding (2005)

These studies show that CNTO 95 is safe and, unlike some other angiogenesis inhibitors, does not seem to inhibit normal physiologic angiogenesis.
Buccal Drug Delivery Systems (1995)

Buccal administration offers certain unique advantages for the drugs which cannot be easily or efficiently administered by oral or intravenous route. However, transbucccal delivery receiived relatively little attention and few well-controlled studies of buccal mucosa permeability have been conducted. The oral mucosa provides a protective covering for the underlying tissue, being as a barrier for microorganisms and toxins. This article extensively reviews the histology of buccal mucosa, permeation studies (both invitro and in vivo) of buccal drug delivery system, their development and various types of techniques and devices available for the delivery of drugs through buccal mucosa.
Voltage balancing in DC/DC multilevel boost converters (2008)

This paper discusses the multilevel boost converter, a DC-DC converter recently proposed. The DC-DC multilevel boost converter is based on one inductor, one switch, 2N-1 diodes and 2N-1 capacitor, for an Nx converter, it is a boost converter able to control and maintain the same voltage in all the N output levels, and able to control the input current. The application proposed in this paper is the voltage balancing of the DC link in a diode clamped multilevel inverter, with the purpose to use it in renewable energy generation feed by a PV panel or by a fuel cell, where the DC input voltage needs to be boosted and regulated, a five level diode clamped multilevel inverter can be used to inject the power directly to the medium voltage distribution grid. The multilevel boost converter will balance the DC-link voltage; experimental results in a scaled low power prototype prove the proposition's principle.
Influence of the mercury vapor pressure on the isothermal growth of HgTe over CdTe (1975)

The theory developed in the preceding article is applied to the epitaxial growth of HgTe on a CdTe substrate under isothermal EDRI conditions. In the absence of excess mercury, two different growth conditions can be distinguished. In the high-temperature case, pure HgTe is present at the surface of the epitaxial layer and the layer thickness is proportional to the square root of the Hg vacancy diffusion coefficient and of the vacancy concentration gradient. At low temperature (&amp;lt;450 °C), a CdHgTe solid solution exists at the surface of the epitaxial layers; its thickness depends linearly on the coefficient of interdiffusion and on the mercury concentration gradient at the surface. Mercury in excess influences the rate of interdiffusion, the evaporation of mercury from the substrate, and therefore the interdiffusion coefficient as well as the layer thickness and the surface composition. It was found that the interdiffusion coefficient D (varying between 0.5 μ2/h for cadmium-rich alloys and 100 μ2/h for mercury-rich compositions) decreases with increasing excess mercury pressure. This variation of the interdiffusion coefficient (only a high-temperature growth is considered here) leads to the final expression for the layer thickness as a function of the excess mercury pressure p0:e=e0√t exp(−kp0). From this formula it is seen that the time dependence of the layer thickness is not influenced by the presence of excess mercury. The surface composition depends only on p0 and not on time. Up to 4 atm, the cadmium content at the surface increases linearly with p0. For p0 ≳ 4 atm the growth of the layer is completely inhibited. These results are discussed on the basis of a mercury vacancy balance in the substrate and in the epitaxial layer. Vacancies created by the Kirkendall effect either diffuse towards the epitaxial layer surface or are annihilated by interaction with mercury diffused from the vapor phase. From the discussion of both mechanisms (taking into account that the layer thickness increases as √t) it follows that the average vacancy concentration and, consequently, the interdiffusion coefficient are independent of time, as is experimentally observed.
