Surface Modification of Plastic Substrates Using Atomic Hydrogen (2008)

The surface properties of a plastic substrate were changed by a novel surface treatment called atomic hydrogen annealing (AHA). In this method, a plastic substrate was exposed to atomic hydrogen generated by cracking of hydrogen molecules on heated tungsten wire. Surface roughness was increased and halogen elements (F and Cl) were selectively etched by AHA. In addition, plastic surface was reduced by AHA. The surface can be modified by the recombination reaction of atomic hydrogen, the reduction reaction and selective etching of halogen atom. It is concluded that this method is a promising technique for improvement of adhesion between inorganic films and plastic substrates at low temperatures.
Self-supervised segmentation of river scenes (2011)

Here we consider the problem of automatically segmenting images taken from a boat or low-flying aircraft. Such a capability is important for autonomous river following and mapping. The need for accurate segmentation in a wide variety of riverine environments challenges the state of the art vision-based methods that have been used in more structured environments such as roads and highways. Apart from the lack of structure, the principal difficulty is the large spatial and temporal variations in the appearance of water in the presence of nearby vegetation and with reflections from the sky. We propose a self-supervised method to segment images into `sky', `river' and `shore' (vegetation + structures) regions. Our approach uses assumptions about river scene structure to learn appearance models based on features like color, texture and image location which are used to segment the image. We validated our algorithm by testing on four datasets captured under varying conditions on different rivers. Our self-supervised algorithm had higher accuracy rates than a supervised alternative, often significantly more accurate, and does not need to be retrained to work under different conditions.
A Cystic Fibrosis Epidemic Strain of <i>Pseudomonas aeruginosa</i> Displays Enhanced Virulence and Antimicrobial Resistance (2005)

The Liverpool epidemic strain (LES) of Pseudomonas aeruginosa is a transmissible aggressive pathogen of cystic fibrosis (CF) patients. We compared transcriptome profiles of two LES isolates with each other and with a laboratory and genetic reference strain (PAO1) after growth to late exponential phase and following exposure to oxidative stress. Both LES isolates exhibited enhanced antimicrobial resistances linked to specific mutations in efflux pump genes. Although transcription of AmpC beta-lactamase was up-regulated in both, one LES isolate contained a specific mutation rendering the ampC gene untranslatable. The virulence-related quorum-sensing (QS) regulon of LES431, an isolate that caused pneumonia in the non-CF parent of a CF patient, was considerably up-regulated in comparison to either isolate LES400, associated with a chronic CF infection, or strain PAO1. Premature activation of QS genes was detected in isolates from both non-CF parents and the CF patient in a previously reported infection episode. LES isolates lacking the up-regulated QS phenotype contained different frameshift mutations in lasR. When fed to Drosophila melanogaster, isolate LES431 killed the fruit flies more readily than either isolate LES400 or strain PAO1, indicating that virulence varies intraclonally. The LES may represent a clone with enhanced virulence and antimicrobial resistance characteristics that can vary or are lost due to mutations during long-term colonization but have contributed to the successful spread of the lineage throughout the CF population of the United Kingdom.
Novos enunciados de projeto em áreas de interesse social: um olhar sobre as Áreas Especiais de Interesse Social de Natal (2003)

Com a retirada do Estado na promocao da moradia atraves de cooperativas ? sistema BNH/INOCOOPs ?, surgiu no Brasil, inicio da decada de 1990, uma nova modalidade de cooperativa habitacional, em um contexto de profunda regressao do financiamento publico e agravamento do deficit habitacional. Desse modo, a producao cooperativada da moradia atraves do sistema de autofinanciamento emerge como uma alternativa para atender os excluidos dos mercados imobiliarios tradicionais e da provisao publica, tendo como objetivo proporcionar aos associados o acesso a casa propria a preco de custo. Nos ultimos anos, em decorrencia do agravamento das restricoes aos emprestimos bancarios e financiamento estatal, a classe media tem encontrado nas cooperativas habitacionais autofinanciadas, a saida para a aquisicao da casa propria. Portanto, se no passado estas cooperativas eram direcionadas para atender as familias de media e baixa renda, mais recentemente, esse sistema cooperativado de producao da moradia vem privilegiando os segmentos de maior renda.
Stream Processing of Healthcare Sensor Data: Studying User Traces to Identify Challenges from a Big Data Perspective (2015)

The Internet of Things (IoT) generates massive streams of data which call for ever more efficient real time processing. Designing and implementing a big data service for the real time processing of such data requires an extensive knowledge of both input load and data distribution in order to provide a service which can cope with the workload. In this context, we study in this paper the challenges inherent to the real time processing of massive data flows from the IoT. We provide a detailed analysis of traces gathered from a well-known healthcare sport-oriented application in order to illustrate our conclusions from a big data perspective.
[Increase of BIRC5 gene expression in non-small cell lung cancer and esophageal squamous cell carcinoma does not correlate with expression of genes SMAC/DIABLO and PML encoding its inhibitors]. (2008)

Survivin (BIRC5) is one of the members of IAP-family apoptosis inhibitors. The BIRCS gene is expressed in most human embryonic tissues and malignant tumors but not in normal differentiated tissues of adult human. It was suggested that BIRC5 proteins inhibit apoptosis and play an essential role in tumorigenesis, makings surviving an attractive target for anticancer therapy. The mechanisms regulating level of survivin are not completely understood. It was supposed that natural inhibitors of survivin, namely SMAC and PML, play an important role in these processes. Using RT-PCR and immunoblotting we analyzed the transcription level of BIRC5, SMAC and PML genes and content of corresponding proteins in normal and tumor human tissues in non-small cell lung cancer and esophageal squamous cell carcinoma. It was demonstrated that BIRC5 is transcribed only in tumor tissues, whereas expression levels of SMAC and PML are the same in normal and tumor tissues. The contents of proteins correspond to levels of mRNA of the respective genes. Thus the increase of level of survivin in tumor tissues is not the result of decrease in content of its inhibitors SMAC and PML, as their content in tumor and normal cells is the same.
Silent pelvic inflammatory disease: Is it overstated? (1995)

Silent PID does not seem to be as common among infertile women as previously thought. This study suggests that in the future, more extensive questions about medical history are needed than have been asked in the past.
Development of Personal Traffic Information On Demand Service(PTIODS) (1997)

This paper presents a Personal Traffic Information On Demand Service (PTIODS) system, which provides users with real-time traffic information and path plan through a wireless communication unit. When a user enters his/her starting point and destination on equipment with two-way communication, the traffic information center determines the shortest path and the estimated time of arrival at the destination. A map is sent with this information to the user for displaying on a simple display unit through a two-way communication unit. In this paper, the authors develop a map database structure for traffic information and a front network database which is designed to avoid computation time explosion usually involved with centralized multi-user processing. For the covering abstract, see IRRD 490001.

Induction of apoptosis by Toll-like receptor-7 agonist in tissue cultures (2003)

Toll-like receptor (TLR)-7 agonists represent a new group of immune response modifiers, which include imiquimod and resiquimod (R-848). Topically applied imiquimod is used for the treatment of both external and perianal genital warts, and benign and malignant epithelial lesions. Based on the induction of interferons and other cytokines in vitro and in vivo, regression of epithelial lesions probably depends on induction of both innate and cellular immune responses. As clinical remission is not always associated with inflammation, other mechanisms may also be involved. Using two different assays for detection of apoptosis (TUNEL test and gel analysis of DNA fragmentation), we observed induction of apoptosis by imiquimod in human epithelial cell lines (HeLa S3) and keratinocytes (HaCaT, A431 cells), as well as in mouse fibroblasts (McCoy cells). These findings suggest that the mode of action of imiquimod to eliminate virus-infected, dysplastic or neoplastic epithelial cells may also include the induction of apoptotic processes.

Nondegenerate solitons and their collisions in Manakov systems (2020)

Recently, we have shown that the Manakov equation can admit a more general class of nondegenerate vector solitons, which can undergo collision without any intensity redistribution in general among the modes, associated with distinct wave numbers, besides the already-known energy exchanging solitons corresponding to identical wave numbers. In the present comprehensive paper, we discuss in detail the various special features of the reported nondegenerate vector solitons. To bring out these details, we derive the exact forms of such vector one-, two-, and three-soliton solutions through Hirota bilinear method and they are rewritten in more compact forms using Gram determinants. The presence of distinct wave numbers allows the nondegenerate fundamental soliton to admit various profiles such as double-hump, flat-top, and single-hump structures. We explain the formation of double-hump structure in the fundamental soliton when the relative velocity of the two modes tends to zero. More critical analysis shows that the nondegenerate fundamental solitons can undergo shape-preserving as well as shape-altering collisions under appropriate conditions. The shape-changing collision occurs between the modes of nondegenerate solitons when the parameters are fixed suitably. Then we observe the coexistence of degenerate and nondegenerate solitons when the wave numbers are restricted appropriately in the obtained two-soliton solution. In such a situation we find the degenerate soliton induces shape-changing behavior of nondegenerate soliton during the collision process. By performing suitable asymptotic analysis we analyze the consequences that occur in each of the collision scenario. Finally, we point out that the previously known class of energy-exchanging vector bright solitons, with identical wave numbers, turns out to be a special case of nondegenerate solitons.
Neural Networks to Improve Distribution State Estimation—Volt Var Control Performances (2012)

Distribution systems must be ready to face upcoming technical and economic constraints: increase of Distributed Generation (DG) connections, changes in network losses and voltage profiles, among others. In this context, new centralized automation functions in distribution system control centers are needed in order to ensure the control of both distribution network and connected DGs. Consequently, state estimators need to be developed for future distribution systems to assess the network's state in real time, i.e., 10 minutes typical time frame, based on real, pseudo-, and virtual measurements. Such state estimation functions are widely used for transmission systems but cannot be transposed directly into distribution systems. Indeed, one of the main issues is the lack of sensors in the distribution network, requiring additional load models to solve observability issues. These load models (also called pseudomeasurements) are usually active and reactive power models at medium to low voltage (MV/LV) substations using often very inaccurate information from historical database or other estimated load curves, for instance. The scale of these errors makes the estimation of all variables in the distribution network difficult. This paper proposes a pseudomeasurement estimation using neural networks in order to improve the results of a distribution state estimator (DSE), used as inputs to a centralized Volt and Var control function.
Plasma Exchange in Neuroimmunological Disorders (2006)

Plasma exchange is a well-established therapeutic procedure commonly used in many neurological disorders of autoimmune etiology. It is thought that the beneficial effects of plasma exchange occur through the elimination of pathognomonic inflammatory mediators, including autoantibodies, complement components, and cytokines. In various neurological disorders, randomized controlled studies have demonstrated the efficacy of plasma exchange (eg, in Guillain-Barré syndrome and other forms of immune neuropathies). Although widely used, the potential benefit of plasma exchange in the treatment of multiple sclerosis, myasthenia gravis, and Lambert-Eaton syndrome is less clear.
Evidence of diffusion via collective hopping in metallic supercooled liquids and glasses (2002)

We report on measurements of the mass dependence (isotope effect E) of Co diffusion in both the glassy as well as the supercooled liquid states in a ${\mathrm{Pd}}_{40}{\mathrm{Cu}}_{30}{\mathrm{Ni}}_{10}{\mathrm{P}}_{20}$ glass. The isotope effect, which is a fingerprint of the diffusion mechanism, is very small (0.1) in both states, suggesting diffusion via highly collective hopping. In particular, E does not change upon isothermal relaxation from the glassy into the supercooled liquid state. Our results lend strong support to the view that even after macroscopic softening of a glass the underlying atomic transport mechanism is still solidlike thermally activated hopping in a considerable temperature range above the caloric glass transition temperature.

Down-Regulation of Transglutaminase 2 Stimulates Redifferentiation of Dedifferentiated Chondrocytes through Enhancing Glucose Metabolism (2017)

Expansion of chondrocytes for repair of articular cartilage can lead to dedifferentiation, making it difficult to obtain a sufficient quantity of chondrocytes. Although previous studies have suggested that culture in a three-dimensional environment induces redifferentiation of dedifferentiated chondrocytes, its underlying mechanisms are still poorly understood in terms of metabolism compared with a two-dimensional environment. In this study, we demonstrate that attenuation of transglutaminase 2 (TG2), a multifunctional enzyme, stimulates redifferentiation of dedifferentiated chondrocytes. Fibroblast-like morphological changes increased as TG2 expression increased in passage-dependent manner. When dedifferentiated chondrocytes were cultured in a pellet culture system, TG2 expression was reduced and glycolytic enzyme expression up-regulated. Previous studies demonstrated that TG2 influences energy metabolism, and impaired glycolytic metabolism causes chondrocyte dedifferentiation. Interestingly, TG2 knockdown improved chondrogenic gene expression, glycolytic enzyme expression, and lactate production in a monolayer culture system. Taken together, down-regulation of TG2 is involved in redifferentiaton of dedifferentiated chondrocytes through enhancing glucose metabolism.
Group location tracking based on representative identity and virtual VLR for transportation systems (2001)

A location tracking scheme known as group location tracking (GLT) is proposed to reduce the location update cost for terrestrial transportation systems (TSs) in personal communication networks. When a TS moves into a new registration area, the GLT scheme, based on a representative identity of the TS and a virtual visitor location register, updates location information by a group location update request message instead of individual location update of users. Compared with the IS-41, the GLT scheme significantly reduces signaling load.
Altitude Control for an Indoor Blimp Robot (2017)

This paper presents design of altitude controller for an indoor blimp robot and its realization. Due to hardware restrictions, the altitude control behavior of blimp is modeled as a switched system with time-varying delay. HOSM differentiator is used as an observer for vertical velocity, it is also used in order to estimate the switching signal. Then a predictor-based controller is conceived, its gain is determined by common Lyapunov function method to ensure the global uniform exponential stability of switched system. Control scheme is implemented by Matlab Simulink, finally, the performance of blimp altitude controller is verified in experiments.
<title>Dielectric coatings for Ag/dielectric hollow glass waveguides</title> (2002)

Different dielectric thin films are being studied in order to facilitate the processing of low loss multiple metallic dielectric hollow glass waveguides (HGWs). In this paper, we present our results for high index lead sulfide (PbS) and low index optical polymers, especially, polystyrene (PS) and cyclic olefin polymer (COP). We have observed that the morphology of the thin film is dependent on the processing conditions. The morphology of the metal and dielectric thin film affects the attenuation of the hollow glass waveguides. We have been successful in depositing and controlling the morphology of high n PbS thin films and low n polymer films. In order to aid in thin film characterization we have also deposited on planar substrates.
The design of a 6-port active calculator (2003)

An approach is presented for realizing circulators in the form of GaAs monolithic microwave integrated circuits (MMICs) without using any ferrite material and external magnets. The configuration is known as an active circulator and is suitable for system applications where a fully integrable, lightweight, and small-size subsystem is required. The circuit is capable of providing 0 dB loss, and return loss and isolation of better than 16 dB and 23 dB, respectively, over an octave or higher bandwidth.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Metalloendoprotease Inhibitors Block Fast Axonal Transport (1989)

Metalloendoprotease activity that was sensitive to the metal chelator 1,10-phenanthroline and to synthetic dipeptide substrates of the enzyme was detected in homogenates of dorsal root ganglia (DRG) and spinal nerve from the bullfrog. Exposure of an intact in vitro preparation of DRG and spinal nerves to 1,10-phenanthroline led to a dose-dependent depression in the accumulation of fast-transported 3H-labeled protein proximal to a nerve ligature. In nonligated preparations, the chelator treatment reduced the amount of transported protein entering the nerve; no marked effect on the transport rate was observed. Exposure of a desheathed region of spinal nerve to 1,10-phenanthroline, while DRG were maintained in control medium, resulted in a slight depression of fast transport. This effect was not dose dependent over the range that produced a dose response when both DRG and spinal nerve were exposed to the drug. Treatment of DRG and spinal nerve with the metalloendoprotease substrate analogues carbobenzoxy (CBZ)-Ser-Leu-amide or CBZ-Gly-Leu-amide inhibited fast axonal transport, whereas treatment with CBZ-Gly-Gly-amide, which is not a substrate, had no detectable effect on transport. Selective exposure of desheathed nerve trunk to CBZ-Ser-Leu-amide inhibited fast transport, but the effect was less marked than when DRG and nerve trunk were treated. Although previous studies have focused on the role of metalloendoprotease activity in exocytosis, the present data suggest that the enzyme may also be involved in earlier stages of intracellular transport.
