Algorithms for Alignment of Co-Channel Speech Signals in Adaptive Speech Separation (2007)

This paper presents preprocessing algorithms for reducing misalignment of co-channel speech signals in order to improve the accuracy of adaptive speech separation. The use of adaptive decorrelation filtering as a front end processor in speech recognition systems improve performance when the input signals from the two channels are synchronized. However the performance of ADF is degraded when the co-channel signals are misaligned. We address this problem by proposing a pre-processor to the ADF with a view to align the co-channel signals. We have implemented two different algorithms for synchronizing the co-channel speech signals using cross-correlation. These algorithms improve the performance of speech recognition.
A measurement and simulation study of transmission lines on microstrip and stacked-pair structure for high speed signals (2002)

In high frequency transmission, crosstalk toward neighbor lines increases because of the strong behavior of electric and magnetic field. In this paper, we present a new transmission structure especially focused on the bus between CPU and memory for high frequency range. And we confirm the superiority of new structure through measurement and simulation study in terms of electromagnetic field analysis.
A Soluble Bis-Chelated Gold(I) Diphosphine Compound with Strong Anticancer Activity and Low Toxicity (2013)

Gold-containing compounds have shown anticancer potential, but their clinical applications have been severely limited by poor stability and high toxicity in vivo. Here, we report a novel soluble bis-chelated gold(I)-diphosphine compound (GC20) with strong anticancer activity and low toxicity. GC20 shows strong antiproliferation potency against a broad spectrum of cancer cell lines including cisplatin-resistant cancer cells (IC50 ≈ 0.5 μM) and significantly reduces tumor growth in several tumor xenografts in mouse models at doses as low as 2 mg/kg. Studies of its mechanism revealed that GC20 specifically inhibits the enzymatic activity of thioredoxin reductase by binding to selenocysteine residue, without targeting other well-known selenol and thiol groups contained in biomolecules. Remarkably, in animal studies GC20 was shown to be well tolerated even at the high dose of 8 mg/kg. Our results strongly suggest that GC20 represents a promising candidate for the development of novel anticancer drugs.
A long-half-life and fibrin-specific form of tissue plasminogen activator in rabbit models of embolic stroke and peripheral bleeding. (1994)

These findings show that by combining increased fibrin specificity with decreased plasma clearance, it is possible to produce a thrombolytic agent that is more convenient and more potent than wild-tpe TPA. At the same time the significant reduction in hemorrhagic conversions may be attributable to the conservation of systemic plasminogen seen with this molecule.

Effect of Dextran Filling in Macroporous HEMA Sorbent on Its Behavior in Dye-Affinity Chromatography (1995)

Abstract Macroporous and microparticulate poly(hydroxyethyl methacrylate) gel (HEMA) and HEMA containing pores filled with a dextran network were used as supports for immobilization of reactive dye Cibacron Blue 3G-A. The performance of both dextran-filled and non-filled HEMA sorbents, with various ligand densities, in dye-ligand affinity chromatography of several enzymes and of bovine albumin were studied. The obtained results show the positive effect of dextran filling on enzyme recovery and on binding capacity of the separation media.
Self-aligning gas/liquid micropump (2002)

In this paper a piezoelectrically driven silicon membrane pump with passive dynamic valves is described. It is designed to pump gases and liquids and to be tolerant to gas bubbles. Reducing the dead volume within the pump, and thus increasing the compression ratio, one achieves the gas pumping. The main advantages and novel features of the pump described in the paper are the self-aligning of the membrane unit to the valve unit and the possibility of using screen-printed PZT as actuator, which enables mass production and thus low-cost micropumps. A liquid pump rate of 1500 μl min−1 and a gas pump rate of 690 μl min−1 were achieved.
Sonication-Assisted Synthesis of Polyelectrolyte-Coated Curcumin Nanoparticles (2010)

A new method of nanoparticle formulation for poorly water-soluble materials was demonstrated for curcumin. The drug was dissolved in organic solvent that is miscible with water (ethanol), and drug nucleation was initiated by gradual worsening of the solution by the addition of an aqueous polyelectrolyte assisted by ultrasonication. Curcumin crystals of 60-100 nm size were obtained depending on the component concentrations, sonication power, and initial solvent. Layer-by-layer shell assembly with biocompatible polyelectrolytes was used to provide a particle coating with a high surface potential and the stabilization of drug nanocolloids. Polyelectrolyte layer-by-layer encapsulation allowed sustained drug release from nanoparticles over the range of 10-20 h.

The Effectof Lanthanum and Barium Additives on the Thermal Stabilization of g-Al2O3 (1998)

The effect of La and Ba additives on the thermal stabilization of g-Al2O3 was investigated through total-surface-area measurements. The parameters considered were additive content, calcination temperature, and calcination period. The effect of precalcination was also studied. It was found that thermal stabilization caused by 3 wt% La and Ba is superior to 6 wt % La or Ba, and the positive effect of 3 wt% La and 3 wt% Ba are almost identical. The nearly threefold increase in the total surface area of 3 wt% La or Ba doped samples calcined above the g - a phase-transition temperature indicates that the aluminate complexes formed with La or Ba during phase transition impart thermal resistance to sintering. Aluminate formation at these temperatures is verified by XRD measurements. Precalcination at 723 K stabilizes the g-Al2O3 structure, leading to higher surface areas in the undoped sample upon sintering.
Two-time-scale feedback design of a class of nonlinear systems (1978)

For a class of nonlinear singularly perturbed systems, feedback stabilizing and near-optimal controls are designed using two separate lower order subsystems. The two-time-scale properties greatly simplify the stability analysis and the nonlinear controller design. Two electric machine examples (a dc motor and a synchronous generator) illustrate the proposed design procedure.
AN EMPIRICAL ANALYSIS OF PAYMENT CARD USAGE<sup>*</sup> (2007)

I exploit a unique data set on the payment card industry to study issues associated with network effects and two‐sided markets. I show that consumers concentrate their spending on a single payment network (single‐homing), although many maintain unused cards that allow the ability to use multiple networks (multi‐homing). Further, I establish a regional correlation between consumer usage and merchant acceptance within the four major networks (Visa, Mastercard, American Express and Discover). This correlation is suggestive of the existence of a positive feedback loop between consumer usage and merchant acceptance.
Radiation-induced cerebellar glioblastoma at the site of a treated medulloblastoma (2005)

Radiation-induced glioblastoma multiforme (GBM) is a rare complication of radiotherapy. The authors report such a case occurring 10 years after treatment of cerebellar medulloblastoma. The patient was a 15-year-old boy who had undergone a gross-total removal of a medulloblastoma and received radiation therapy at the age of 5 years. He had experienced no tumor recurrences for 10 years until a new enhancing mass was found at the original site of the medulloblastoma. Following its resection the new lesion was found to be a GBM and there was no evidence of a medulloblastoma. The second tumor developed at the same site as the previous one after a sufficient latent period and fulfilled the criteria for a radiation-induced neoplasm. The original tumor cells expressed synaptophysin without p53 overexpression, a characteristic feature of medulloblastomas. In contrast, cells from the later tumor expressed glial fibrillary acidic protein and p53 but not synaptophysin. A sequence analysis of the p53 gene showed deletion at codon 233 and a C to G transition at codon 278 in the GBM but no mutation in the medulloblastoma. A GBM specimen revealed no amplification of the epidermal growth factor receptor compared with a normal control specimen. In conclusion, the clinical features of a radiation-induced GBM are similar to that of the primary GBM, whereas its genetic alterations render it a secondary GBM. These findings indicate that radiation-induced GBM should be considered a distinct clinical entity.
IFN inhibits inflammatory responses and protective immunity in mice infected with the nematode parasite, <i>Nippostrongylus brasiliensis</i>. (1993)

Mice infected with the gastrointestinal nematode parasite Nippostrongylus brasiliensis (Nb) develop responses associated with enhanced production of IL-4 (increased serum IgE levels and intestinal mucosal mastocytosis) and IL-5 (tissue and peripheral blood eosinophilia). The antagonistic effects of IFN on IL-4-mediated responses prompted an examination of the effects of IFN on the host response to Nb. Treatment with rIFN-alpha and rIFN-gamma induced a marked increase in parasite egg production (fecundity) in BALB/c mice infected with Nb and delayed intestinal expulsion of adult worms. Treatment with rIFN-alpha or rIFN-gamma also inhibited the rise in peripheral blood eosinophilia that follows inoculation with Nb, and the intensity of pulmonary perivascular tissue eosinophilia. However, Nb-induced increases in serum IgG levels and intestinal mastocytosis were only temporarily delayed by IFN. Induction of endogenous IFN production by injection of fixed Brucella abortus into mice infected with Nb also resulted in an increased worm fecundity and delayed adult worm expulsion. These effects were ablated when mice given Brucella abortus also received injections of neutralizing anti-IFN antibodies. Thus, IFN inhibit host protective immunity to Nb, perhaps by interfering with the production and effects of Th2 cytokines.
Photochromism of spirooxazines I. Investigation of the primary processes in the ring‐opening reaction by picosecond time‐resolved absorption and emission spectroscopy (1987)

Abstract The heterolytic bond cleavage between the spiro‐carbon and the neighbouring oxygen is commonly accepted as the primary photochemical step after exciting indolino‐spirooxazines with UV‐photons. The nonplanar intermediate “X” generated in this way is said to relax very fast to a distribution of open forms, which are in structure similar to merocyanines. In this paper, the existence of an intermediate “X” is proven for various derivatives of indolino‐spironaphthoxazines. The build‐up time of these “X”‐forms is generally shorter than 2 ps, and the following reaction to the planar forms takes 2 to 12 ps depending on the nature of the solvent as well as the kind of substituent added to the parent molecule. In contrast to nitro‐substituted compounds the triplet route is found to be negligible in the investigated derivatives.
A review on self-cleaning coatings (2011)

This review article summarizes the key areas of self-cleaning coatings, primarily focusing on various materials that are widely used in recent research and also in commercial applications. The scope of this article orbits around hydrophobic and hydrophilic coatings, their working mechanism, fabrication techniques that enable the development of such coatings, various functions like Anti-icing, Electro-wetting, Surface switchability and the areas where selfcleaning technology can be implemented. Moreover, different characterization techniques and material testing feasibilities are also analyzed and discussed. Though several companies have commercialized a few products based on self-cleaning coating technology, much potential still remains in this field.
Postgrowth control of the quantum-well band edge for the monolithic integration of widely tunable lasers and electroabsorption modulators (2003)

We describe a quantum-well intermixing process for the monolithic integration of various devices, each with a unique band edge. The process involves a single ion implant followed by multiple etch and anneal cycles. We have applied this method to design and fabricate widely tunable sampled-grating distributed Bragg reflector lasers with integrated electroabsorption modulators. The devices employ three unique band edges, and demonstrate exceptional tuning, gain, and absorption characteristics.
Multi-criteria-based active learning for named entity recognition (2004)

In this paper, we propose a multi-criteria-based active learning approach and effectively apply it to named entity recognition. Active learning targets to minimize the human annotation efforts by selecting examples for labeling. To maximize the contribution of the selected examples, we consider the multiple criteria: informativeness, representativeness and diversity and propose measures to quantify them. More comprehensively, we incorporate all the criteria using two selection strategies, both of which result in less labeling cost than single-criterion-based method. The results of the named entity recognition in both MUC-6 and GENIA show that the labeling cost can be reduced by at least 80% without degrading the performance.

3D building modeling and reconstruction using photometric satellite and aerial imageries (2012)

In this thesis, the problem of three dimensional (3D) reconstruction of building models using photometric satellite and aerial images is investigated. Here, two systems are presented: 1) 3D building reconstruction using a nadir single-view image, and 2) 3D building reconstruction using slant multiple-view aerial images. The first system detects building rooftops in orthogonal aerial/satellite images using a hierarchical segmentation algorithm and a shadow verification approach. The heights of detected buildings are then estimated using a fuzzy rule-based method, which measures the height of a building by comparing its predicted shadow region with the actual shadow evidence in the image. This system finally generated a KML (Keyhole Markup Language) file as the output, that contains 3D models of detected buildings. The second system uses the geolocation information of a scene containing a building of interest and uploads all slant-view images that contain this scene from an input image dataset. These images are then searched automatically to choose image pairs with different views of the scene (north, east, south and west) based on the geolocation and auxiliary data accompanying the input data (metadata that describes the acquisition parameters at the capture time). The camera parameters corresponding to these images are refined using a novel point matching algorithm. Next, the system independently reconstructs 3D flat surfaces that are visible in each view using an iterative algorithm. 3D surfaces generated for all views are combined, and redundant surfaces are removed to create a complete set of 3D surfaces. Finally, the combined 3D surfaces are connected together to generate a more complete 3D model. For the experimental results, both presented systems are evaluated quantitatively and qualitatively and different aspects of the two systems including accuracy, stability, and execution time are discussed.
A EDUCAÇÃO INFORMAL DA JUVENTUDE NA DIOCESE DE SANTA CRUZ DO SUL – 1959/1986 (2001)

<span style="font-size: small;">O presente trabalho tem como finalidade verificar as estratégias utilizadas pela Igreja Católica da diocese de Santa Cruz do Sul na educação informal da juventude, durante a gestão do primeiro bispo, Dom Alberto Etges. Analisou-se os documentos produzidos durante o período de 1959/1986, que deixam claro a opção do bispo e da diocese de investir na educação informal da juventude, independente de sua realidade social. A JAC – Juventude Agrária Católica – foi a primeira escola de formação e destinava-se aos jovens do meio rural. Durante o regime militar, os Movimentos de Encontro, em especial o Emaús, atendeu os jovens dos centros urbanos e os Grupos Paroquiais atuaram no meio rural, mas sem que houvesse uma unidade na formação da juventude. E na década de 80, cada meio específico. Por fim, pode-se afirmar que a diocese de Santa Cruz do Sul, através do Setor da Juventude, contribuiu com seu projeto de educação informal para a formação dos jovens. Muitas das atuais lideranças comunitárias, políticas, educacionais, comerciais e empresariais, tiveram passagem nos quadros de educação informal da diocese.</span>

A modular verifiable exception handling mechanism (1985)

This paper presents a new model for exception handling, called the replacement model. The replacement model, in contrast to other exception-handling proposals, supports all the handler responses of resumption, termination, retry, and exception propagation, within both statements and expressions, in a modular, simple, and uniform fashion. The model can be embedded in any expression-oriented language and can also be adapted to languages which are not expression oriented with almost all the above advantages. This paper presents the syntactic extensions for embedding the replacement model into Algol 68 and its operational semantics. An axiomatic semantic definition for the model can be found in [27].
