Autoimmune Hepatitis and Celiac Disease: Case Report Showing an Entero-Hepatic Link (2010)

Celiac disease is an autoimmune disorder primarily targeting the small bowel, although extraintestinal extensions have been reported. The autoimmune processes can affect the liver with manifestations such as primary biliary cirrhosis and autoimmune hepatitis. We describe a 61-year-old woman with celiac disease and an increased levels of aminotransferases. The persistence of increased levels of aminotransferases after 1 year of gluten-free diet and the positivity for an anti-nuclear and anti-double-strand DNA antibodies led to a misdiagnosis of systemic lupus erythematosus-related hepatitis. Based on these findings the patient was placed on steroids, which after a few months were stopped because of the onset of diabetes mellitus. Soon after steroid withdrawal, the patient had a marked increase in aminotransferases and γ-globulins, and a liver biopsy revealed chronic active hepatitis. A course of three months of steroids and azathioprine normalized both biochemical and clinical parameters. Currently the patient is symptom-free and doing well. In conclusion, a hypertransaminasemia persisting after a gluten-free diet should be interpreted as a sign of coexisting autoimmune liver disease. Any autoantibody positivity (in this case to ANA and anti-dsDNA) should be carefully considered in order to avoid misdiagnosis delaying appropriate clinical management.
Current Phase Lead Compensation in Single-Phase PFC Boost Converters with a Reduced Switching Frequency to Line Frequency Ratio (2006)

Traditional design of the current loop controller in a single-phase PFC boost converter is not suitable for applications with higher line frequencies (up to 800 Hz) because of the zero-crossing distortion and high harmonic content due to the current phase lead effect. Increasing the control bandwidth and switching frequency in order to avoid this effect would reduce converter efficiency and is objectionable. The paper presents the leading-phase admittance cancellation (LPAC) technique, which improves the current-shaping control structure and eliminates the current phase lead without increasing the bandwidth requirement. The LPAC method extends the allowable line frequency range from 1/150 to 1/5 of the current loop bandwidth. The LPAC method is load-invariant and superior to other previously proposed methods. The LPAC network can be added to existing designs, which would require only two passive components in the simplest case.
[Mechanisms underlying generation of cancer pain]. (2011)

As advances in cancer detection and treatment have increased the life expectancy of cancer patients, more attention to improving patient's quality of life (QOL) is needed. Among symptoms accompanying cancer, pain has strong impact on QOL. Most of cancer patients will experience moderate to severe pain and/or neuropathy during the course of their disease. Cancer pain can arise from different processes, either by direct tumor infiltration/involvement, or toxicity relating to chemotherapy used to treat cancer. The World Health Organization (WHO) has proposed a structured approach to drug selection for cancer pain, known as the "WHO analgesic ladder". However, several types of pain including bone cancer pain and chemotherapy-induced painful peripheral neuropathy are difficult to treat. The development of optimal analgesics for cancer pain has been hampered by the lack of understanding basic mechanisms that contribute to cancer pain. Recently, preclinical models of bone cancer pain and paclitaxel-induced painful peripheral neuropathy have been developed. These models have begun to provide insight into the mechanisms by which cancer pain is induced and how cancer pain-related sensory information is processed. In this paper, we review mechanism of cancer pain.
Map Image Compression for Real-Time Applications (2002)

Digital maps can be stored and distributed electronically using compressed raster image formats. We introduce a storage system for the map images that supports compact storage size, decompression of partial image, and smooth transitions between various scales. The main objective of the proposed storage system is to provide map images for real-time applications that use portable devices with low memory and computing resources. Compact storage size is achieved by dividing the maps into binary layers, which are compressed using context-based statistical modeling and arithmetic coding. Partial image decompression is supported by tiling the image into blocks and implementing direct access to the compressed blocks. In this paper, we give overview of the system architecture, describe the compression technique, and discuss implementation aspects. Experimental results are given both in terms of compression ratios and image retrieval timings.
Learning Topic Models - Going beyond SVD (2012)

Topic Modeling is an approach used for automatic comprehension and classification of data in a variety of settings, and perhaps the canonical application is in uncovering thematic structure in a corpus of documents. A number of foundational works both in machine learning and in theory have suggested a probabilistic model for documents, whereby documents arise as a convex combination of (i.e. distribution on) a small number of topic vectors, each topic vector being a distribution on words (i.e. a vector of word-frequencies). Similar models have since been used in a variety of application areas; the Latent Dirichlet Allocation or LDA model of Blei et al. is especially popular. Theoretical studies of topic modeling focus on learning the model's parameters assuming the data is actually generated from it. Existing approaches for the most part rely on Singular Value Decomposition(SVD), and consequently have one of two limitations: these works need to either assume that each document contains only one topic, or else can only recover the span of the topic vectors instead of the topic vectors themselves. This paper formally justifies Nonnegative Matrix Factorization(NMF) as a main tool in this context, which is an analog of SVD where all vectors are nonnegative. Using this tool we give the first polynomial-time algorithm for learning topic models without the above two limitations. The algorithm uses a fairly mild assumption about the underlying topic matrix called separability, which is usually found to hold in real-life data. A compelling feature of our algorithm is that it generalizes to models that incorporate topic-topic correlations, such as the Correlated Topic Model and the Pachinko Allocation Model. We hope that this paper will motivate further theoretical results that use NMF as a replacement for SVD - just as NMF has come to replace SVD in many applications.
An ultraviolet fluorescence-based method for identifying and distinguishing protein crystals (2004)

Intrinsic ultraviolet fluorescence has been investigated as a rapid non-invasive method for identifying and distinguishing protein crystals. An epi-fluorescence microscope, which provides for excitation and viewing of fluorescence from above the sample, and a straight-through geometry, which provides excitation from above and views fluorescence from underneath the sample, were tested with protein and non-protein crystal samples. In both systems the protein crystals were observed to fluoresce brightly, providing a high contrast against background solution fluorescence, thus enabling protein crystals to be identified and distinguished from non-protein crystals.
Two Heads Are Better than One: The Collaboration between AI and OR (1987)

The MS/OR profession has, in a single generation, grown from birth to a lively adulthood and is playing an important role in the management of our private and public institutions. This success should raise our aspirations. We should aspire to increase the impact of MS/OR by incorporating the AI kit of tools that can be applied to ill-structured, knowledge-rich, nonquantitative decision domains that characterize the work of top management and that characterize the great policy decisions that face our society.
<title>Terfenol-D nonlinear vibration absorber</title> (1997)

An active non-linear vibration absorber for flexible structures is developed. The absorber exploits the inherent quadratic nonlinearity of the actuator material Terfenol-D to produce a two-to-one autoparametric resonance between the forced vibrations of a structure and a second-order analog controller circuit. Nonlinear resonance of this type exhibits the well-known saturation phenomenon. When the structure is forced near resonance, its response saturates to a small value. This type of control has been demonstrated by previous researchers using linear actuators where nonlinearities were introduced via the analog circuit. In contrast, we use the natural nonlinearity of the Terfenol-D material to achieve the same results. We develop the theory and present experimental results for the control of the first and second modes of a cantilever beam. We also consider the application of the strategy experimentally when the forcing is due to a rotating imbalance. In this case, the excitation source is nonideal. Our results indicate that the saturation based control technique implemented with a Terfenol-D actuator constitutes an effective nonlinear vibration absorber.

It also presents a brief look forward at some of the continued innovations now emerging in these areas.
FET Mixers for Communication Satellite Transponders (2005)

Two different types of FET mixer circuits have been developed for 6/4 GHz frequency translation for communications sateIIite transponder. Gate mixer uses non-linear I/sub d/ - V/sub g/ characteristic, with LO being injected into the gate circuit, while in the drain mixer the LO is injected into the drain circuit and non-linear I/sub d/ - V/sub d/ characteristic is utilized. Both circuits yielded conversion gains up to 3 dB over 500 MHz bandwidth. However, the noise figure of the drain mixer as low as 4 dB was measured compared with 5.7 dB for the gate mixer.
A new method to measure parameters of frequency-selective radio channels using power measurements (2001)

This paper describes a method of deriving channel parameters for a time-dispersive (=frequency-selective) radio channel from simple wide-band power measurements. A novel relationship is found allowing the estimation of the root-mean-square (RMS) delay spread from such data. Furthermore, we describe a set of equations that can be used for fitting the (measured) channel parameters to a mathematical model, the so-called frequency-domain (FD) model. We also show a simulation procedure, which directly implements the mathematical description of the channel. The output of this procedure-realizations of frequency-selective channel transfer functions-may be used for instance in the investigation of OFDM systems. The study is restricted to the small-scale modeling; Rayleigh and Ricean fading channels are considered. The estimation of the RMS delay spread is based on the frequency-domain level crossing rate (LCR/sub f/), which is derived from the FD-channel model. It is shown that the RMS delay spread is proportional to the LCR/sub f/. Because of the simple hardware required for finding the LCR/sub f/, the suggested measurement method is particularly interesting for the millimeter-wave frequency band (>30 GHz). However, it can be used at other frequencies as well, where standard laboratory equipment is sufficient for conducting the measurements. The accuracy of this technique depends on the bandwidth observed and can be increased further by combining multiple measurements performed within a small local area.
<title>Integrated GaAs Optical Receiver</title> (1981)

Recent improvements in fiber optic semiconductor components (i.e. lasers and detectors) will lead to the rapid deployment of fiber optic systems in the next few years. This does not, however, signal the end of research in semiconductor optoelectronics, but rather the opening of new and ultimately more widespread application of optoelectronic devices. New and powerful signal processing and data transmission functions will become possible by the marriage of optical and electronic functions on a single monolithic wafer.

The place of drama in ritual African theatre (2014)

Ritual drama staged in traditional African festivals: large open spaces big enough to accomodate actors and audiences who are sometimes in thousands. The main determinant of location, however, is not just availability of space, but a place that is ritually significant in the experience of the people. At festival time this place assumes its metaphysical reality and is a piece of sanctified ground.
A Framework for High-Accuracy Privacy-Preserving Mining (2005)

To preserve client privacy in the data mining process, a variety of techniques based on random perturbation of individual data records have been proposed recently. In this paper, we present FRAPP, a generalized matrix-theoretic framework of random perturbation, which facilitates a systematic approach to the design of perturbation mechanisms for privacy-preserving mining. Specifically, FRAPP is used to demonstrate that (a) the prior techniques differ only in their choices for the perturbation matrix elements, and (b) a symmetric perturbation matrix with minimal condition number can be identified, maximizing the accuracy even under strict privacy guarantees. We also propose a novel perturbation mechanism wherein the matrix elements are themselves characterized as random variables, and demonstrate that this feature provides significant improvements in privacy at only a marginal cost in accuracy. The quantitative utility of FRAPP, which applies to random-perturbation-based privacy-preserving mining in general, is evaluated specifically with regard to frequent-itemset mining on a variety of real datasets. Our experimental results indicate that, for a given privacy requirement, substantially lower errors are incurred, with respect to both itemset identity and itemset support, as compared to the prior techniques.
Developmental Regulation of Early Serotonergic Neuronal Differentiation: The Role of Brain-Derived Neurotrophic Factor and Membrane Depolarization (1995)

The RN46A cell line was derived from Embryonic Day 13 rat medullary raphe cells by infection with a retrovirus encoding the temperature-sensitive mutant of SV40 large T antigen. This cell line is neuronally restricted and constitutively differentiates following a shift to nonpermissive temperature. Undifferentiated RN46A cells express low levels of tryptophan hydroxylase (TPH), low-affinity neurotrophin receptor (p75NTR), and trkB immunoreactivities, but no detectable levels of serotonin (5HT) immunoreactivity. TrkB, p75NTR, and TPH, but not 5HT, expressions increase with differentiation and treatment with brain-derived neurotrophic factor (BDNF). 5HT synthesis in RN46A cells requires initial treatment with BDNF, followed by growth under partial membrane depolarizing conditions. Embryonic raphe cultures treated similarly with BDNF and partial depolarizing conditions also demonstrate increased 5HT synthesis. The sodium-dependent transporter for 5HT reuptake is present in undifferentiated RN46A cells, and the apparent Km and Bmax are unchanged by differentiation or BDNF treatment and membrane depolarization. The high-affinity 5HT1A receptor is present in both undifferentiated and differentiated RN46A cells, and while the Kd is unaffected by differentiation or BDNF/membrane depolarization, the Bmax increases 20-fold after differentiation and 3.5-fold further with BDNF under depolarizing conditions. The expression of the synaptic vesicular monoamine transporter, as determined by the binding of [125I]iodovinyltetrabenazine, also increases in RN46A cells with differentiation. However, 5HT release is constitutive and is independent of acute membrane depolarization. Collectively these data indicate that distinct aspects of serotonin metabolism are differentially regulated during development and suggest that 5HT may function as a developmental signal in an autocrine loop during early serotonergic differentiation.

Kinetics of the Oxidation of <i>D</i>‐Glucose and Cellobiose by Acidic Solution of <i>N</i>‐Bromoacetamide Using Transition Metal Complex Species, [RuCl<sub>3</sub>(H<sub>2</sub>O)<sub>2</sub>OH] −, as Catalyst (2008)

Abstract The kinetics of Ru(III)‐catalyzed and Hg(II)‐co‐catalyzed oxidation of D ‐glucose (Glc) and cellobiose (Cel) by N ‐bromoacetamide (NBA) in the presence of perchloric acid at 40 °C have been investigated. The reactions exhibit the first order kinetics with respect to NBA, but tend towards the zeroth order to higher NBA. The reactions are the first order with respect to Ru(III) and are fractional positive order with respect to [reducing sugar]. Positive effect of Cl − and Hg(OAc) 2 on the rate of reaction is also evident in the oxidation of both reducing sugars. A negative effect of variation of H + and acetamide was observed whereas the ionic strength ( µ ) of the medium had no influence on the oxidation rate. The rate of reaction decreased with the increase in dielectric constant and this enabled the computation of d AB , the size of the activated complex. Various activation parameters have been evaluated and suitable explanation for the formation of the most reactive activated complex has been given. The main products of the oxidation are the corresponding arabinonic acid and formic acid. HOBr and [RuCl 3 (H 2 O) 2 OH] − were postulated as the reactive species of oxidant and catalyst respectively. A common mechanism, consistent with the kinetic data and supported by the observed effect of ionic strength, dielectric constant and multiple regression analysis, has been proposed. Formation of complex species such as [RuCl 3 ·S·(H 2 O)OH] − and RuCl 3 ·S·OHgBr·OH during the course of reaction was fully supported by kinetic and spectral evidences.

Content-Based Intelligent Routing and Message Processing in Enterprise Service Bus (2008)

Enterprise Service Bus (ESB) provides a layer on top of an implementation of an enterprise messaging system. The ESB provides a highly distributed, event-driven Service Oriented Architecture (SOA) that combines Message Oriented Middleware (MOM), Web services,intelligent routing based on content, and XML data transformation. ESB transmits and receives standard set of messages. When it receives a message, it routes it to the appropriate application. Content-based intelligent routing supports service selection and composition. However, current ESB software can only support fixed routing by static configuration files. This paper proposes framework to enable the content-based intelligent routing path construction and message routing. In proposed framework there are 3 main layers: Business Process, ESB and Implementation Layer to define the routing tables and mechanisms of message routings, to support service selection preferences and facilitate the service selection based on message content.
Printability and Ink-Coating Interactions in Inkjet Printing (2007)

Inkjet is a digital printing process where the ink is ejected directly onto a substrate from a jet device driven by an electronic signal. Most inkjet inks have a low viscosity and a low surface tension, which put high demands on the coating layer’s porosity and absorbency characteristics. The aim of this study has been to gain an increased knowledge of the mechanisms that control the sorption and fixation of inkjet inks on coated papers. The focus has been on printability aspects of high print quality (although not photographic quality) laboratory-coated inkjet papers for printers using aqueous-based inks. Papers coated solely with polyvinyl alcohol (PVOH) and starch presented excellent gamut values and good print sharpness over the uncoated substrate, due to good film-forming characteristics observed by light microscopy and ESCA. ESEM analyses showed the complexity and variation of PVOH surface structures, which has probably explained the wide scatter in the colour-to-colour bleed results. Pure PVOH coatings also gave a surface with high gloss variations (2-8 times greater than that of commercial inkjet papers), prolonged ink drying time, and cracked prints when using pigmented inks. When an amorphous silica gel pigment (with broad pore size distribution) was used in combination with binder, a new structure was formed with large pores in and between the pigments and a macro-roughness generated by the large particles. The inkjet ink droplets could quickly penetrate into the large pores and the time for surface wicking was reduced, which was beneficial for the blurriness. However, the macro-roughness promoted bulk spreading in the coarse surface structure, and this tended to increase the line width. Finally, when the ink ends up within the coating, the colorant is partly shielded by the particles, and this reduced the gamut area to some extent. The binder demand of the silica pigments was strongly related to their pore size distributions. Silica gel required two to three times the amount of binder compared to novel surfactant-templated mesoporous silica pigments (with small pores and narrow pore size distribution). This finding was attributed to the significant penetration of PVOH binder into the pores in the silica gel, thereby, increasing its binder demand. Furthermore, this binder penetration reduced the effective internal pore volume available for rapid drainage of the ink vehicle. Consequently, the surfactant-templated pigments required significantly lower amounts of binder, and gave improvements in print quality relative to the commercial pigment.
