Sharing Clusters among Related Groups: Hierarchical Dirichlet Processes (2004)

Bayesian model for clustering problems involving multiple groups of data. Each group of data is modeled with a mixture, with the number of components being open-ended and inferred automatically by the model. Further, components can be shared across groups, allowing dependencies across groups to be modeled effectively as well as conferring generalization to new groups. Such grouped clustering problems occur often in practice, e.g. in the problem of topic discovery in document corpora. We report experimental results on three text corpora showing the effective and superior performance of the HDP over previous models. 1
Cartilaginous Transdifferentiation of Rat Tenosynovial Cells Under the Influence of Bone Morphogenetic Protein in Tissue Culture (1988)

In an in vitro system cartilage tissue was formed from the patellar ligament of young adult rats in the crevices of bone matrix gelatin (BMG) under the influence of bone morphogenetic protein (BMP). The rate of cartilage induction was 75% (six of eight) for the explants using patellar ligaments of rat knee joints. Almost the same rate was observed, 67% (four of six), for explants of ligament with fatty tissue. Tenosynovial cells and synovial cells from the surface of ligaments are potent responders to BMP, and this property may be applied to accelerate the biologic attachment of excised tendons and ligaments in clinical practice.

A user browsing model to predict search engine click data from past observations. (2008)

Search engine click logs provide an invaluable source of relevance information but this information is biased because we ignore which documents from the result list the users have actually seen before and after they clicked. Otherwise, we could estimate document relevance by simple counting. In this paper, we propose a set of assumptions on user browsing behavior that allows the estimation of the probability that a document is seen, thereby providing an unbiased estimate of document relevance. To train, test and compare our model to the best alternatives described in the Literature, we gather a large set of real data and proceed to an extensive cross-validation experiment. Our solution outperforms very significantly all previous models. As a side effect, we gain insight into the browsing behavior of users and we can compare it to the conclusions of an eye-tracking experiments by Joachims et al. [12]. In particular, our findings confirm that a user almost always see the document directly after a clicked document. They also explain why documents situated just after a very relevant document are clicked more often.
Analysis of the Set of GABAA Receptor Genes in the Human Genome (2004)

The genes of the ionotropic gamma-aminobutyric acid receptor (GABR) subunits have shown an unusual chromosomal clustering, but only now can this be fully specified by analyses of the human genome. We have characterized the genes encoding the 18 known human GABR subunits, plus one now located here, for their precise locations, sizes, and exon/intron structures. Clusters of 17 of the 19, distributed between five chromosomes, are specified in detail, and their possible significance is considered. By applying search algorithms designed to recognize sequences of all known GABR-type subunits in species from man down to nematodes, we found no new GABR subunit is detectable in the human genome. However, the sequence of the human orthologue of the rat GABR rho3 receptor subunit was uncovered by these algorithms, and its gene could be analyzed. Consistent with those search results, orthologues of the beta4 and gamma4 subunits from the chicken, not cloned from mammals, were not detectable in the human genome by specific searches for them. The relationships are consistent with the mammalian subunit being derived from the beta line and epsilon from the gamma line, with mammalian loss of beta4 and gamma4. In their structures the human GABR genes show a basic pattern of nine coding exons, with six different genomic mechanisms for the alternative splicing found in various subunits. Additional noncoding exons occur for certain subunits, which can be regulatory. A dicysteine loop and its exon show remarkable constancy between all GABR subunits and species, of deduced functional significance.
Summary of findings. (2005)

This chapter provides a summary of the findings related to the hypotheses and research objectives outlined in Chapter 4. A thorough discussion of these findings and data analysis is found in Chapter 8, Variations Between Planned and Realized Behaviours; Chapter 9, Influence of Product Information on Planned and Realized Consumption Activities; and Chapter 10, Influence of Consumer Characteristics on Planned and Realized Behaviours. These chapters also mention key conceptual and managerial implications arising from the analysis, although a deeper discussion is given in Chapter 11, Strategic Implications and Discussion. The analysis involves six dependent variables: spending, length of stay, attractions, activities, destinations and accommodation; seven independent or moderating variables: geographic origin, income, product experience, motivation, education, travel party size; and one other independent variable, product information namely, visitor's information guide. Aggregation of some variables was necessary to facilitate tests for associations among the criterion and predictor variables e.g. responses for the variables 'Attractions' and 'Activities' were aggregated into ratio-scale variables, ranging from 0 to 6 and 0 to 13, respectively. The structure of the chapter is as follows. First, the results of hypothesis testing are shown. The hypotheses are grouped under three headings, which represent the three sets of relationship being examined in this study: relationship between planned and realized consumption behaviours; effects of product information on planned and realized consumption behaviours; and influence of customer characteristics on planned and unplanned consumption behaviours. Secondly, the main and interaction effects are examined and discussed briefly. Thirdly, two models are offered and explained: the original model detailing the theoretical assumptions underpinning the research, and a revised model based on the research findings that extend our understanding of consumer behaviour. Fourthly, the application of Mintzberg's strategy model to the planned and realized behaviours of consumers, a key objective of this study, is undertaken.
MCM-41-Supported Oxo-vanadium(IV) Complex: A Highly Selective Heterogeneous Catalyst for the Bromination of Hydroxy Aromatic Compounds in Water (2011)

An ecofriendly solid catalyst has been synthesized by anchoring vanadium(IV) into organically modified MCM-41. First, the surface of Si-MCM-41 was modified with 3-aminopropyl-triethoxysilane (3-APTES), the amine group of which upon condensation with ortho-hydroxy-acetophenone affords a N(2)O(2)-type Schiff base moiety in the mesoporous matrix. The Schiff base moieties were used to anchor oxo-vanadium(IV) ions. The prepared catalyst has been characterized by UV-vis, IR spectroscopy, small-angle X-ray diffraction (SAX), nitrogen sorption, and transmission electron microscopy (TEM) studies. It is observed that the mesostructure has not been destroyed in the multistep synthesis procedure, as evidenced by SAX and TEM measurements. The catalyst has shown unprecedented high conversion as well as para selectivity toward the bromination of hydroxy aromatic compounds using aqueous 30% H(2)O(2)/KBr in water. The reaction proceeds according to the stoichiometric ratio, and the monobrominated product was obtained as the major product using a stoichiometric amount of the bromine source. The immobilized complex does not leach or decompose during the catalytic reactions, showing practical advantages over the free metal complex.
Motion vision and tracking for robots in dynamic, unstructured environments (1992)

The use of robots in dynamic and unstructured environments poses difficult challenges for machine vision. The vision systems for such robots must report changes in the world quickly and must deal with objects that have not been previously seen or specified.
A promising approach to building such vision systems is to construct generally applicable, modular vision services that compute summarizations of camera data that are of direct utility for action. In this thesis it is argued that such modular vision services can serve to connect machine vision to robots in dynamic, unstructured environments.
The thesis describes a real-time vision service that picks out and monitors non-rigid moving objects in natural scenes. The tracking service uses correlation-based optical flow for both picking out, and monitoring the camera-relative extent of moving objects. The algorithms that comprise this service have been implemented on both massively parallel SIMD, and small-scale parallel MIMD hardware. As these algorithms are intended to be used for real-time robot systems, the algorithms and their complexity are described in detail.
The tracking service has been used to build two camera-panning robot systems. Whenever a large object moves into view, the object is picked out and tracked, while the robot pans the camera to keep the object centered in the field of view. The robots have successfully tracked people walking around for long periods. These functioning robots demonstrate both the utility of the tracking vision service itself, and the manner in which such vision services can be integrated into complete systems.
Highly nonlinear bismuth-oxide fiber for smooth supercontinuum generation at 1.5 �m (2004)

Short lengths of highly nonlinear bismuth-oxide fiber are used to generate smooth supercontinuum spanning from 1200 nm to 1800 nm, with sub-0.5 nJ pulse energies. The spectral broadening in a 2-cm length of this fiber was used to compress 150-fs pulses to 25 fs.
EFFECT OF LEVEL OF STRUCTURED PROTEIN FIBER ON QUALITY OF MECHANICALLY DEBONED CHICKEN MEAT PATTIES (1978)

ABSTRACT Mechanically deboned chicken meat (without skin) and chicken (with skin) were combined with 15 or 25% structured protein fiber (SPF) to subjectively and objectively evaluate the quality of patties. Proximate composition, water‐holding capacity, color, texture, and cooking loss were objectively determined. Products were characterized by the Quantitative Descriptive Analysis sensory technique. Raw patties containing 15% SPF had a higher water‐holding capacity than patties with 25% SPF. Cooked patties with 25% SPF required significantly more force to shear, exhibited higher cooking losses, and were characterized as more chewy and elastic, less moist, and more desirable than 15% SPF patties. Textural properties of patties containing mechanically deboned poultry meat were improved by adding 25% SPF; however, cook yield was greater for patties with 15% SPF.
Type c Ferri- and Ferrohemochrome Formation between Hemin c, Amino Acids, and Peptides (1968)

Interaction of various amino acids and peptides with hemin c or heme octapeptide has been studied. The imidazole group of histidine, the sulfur of methionine, and the indole of tryptophan were definitely established as potential heme-binding groups in such a model system at neutral pH. Methionine or methionine in a synthetic peptide gave type c ferri- and ferrohemochrome spectra with hemin c or heme octapeptide. However, the positions of the maxima of the α- and β-bands of the thioether-hemin c complex were at 552.5 and 523 mµ, respectively, and those of the thioetherheme octapeptide were located at 552 and 521 mµ, as compared to 550 and 520 mµ for cytochrome c. The methionine in a synthetic peptide gave a higher absorbance ratio of the α- and β-band with the model heme octapeptide than that obtained by coordination with free methionine alone. The new findings that tryptophan could coordinate with ferric iron of hemin c and that tryptophan in a synthetic tetrapeptide could coordinate with either ferric or ferrous iron of heme-octapeptide suggested the possibility that mixed hemochromes (histidine-iron-tryptophan) may be formed in cytochrome c. The δ-band in cytochrome c is not characteristic of the spectrum of ferrocytochrome c but was obtained by the interaction between reduced metalloporphyrin and two ligand complexes. The characteristic type c spectra were obtained only by the interaction between two ligands and mesohemes containing thioether bonds.
Simultaneous acquisition of spectral image information (1991)

A technique for the simultaneous acquisition of spectral image information, which implies spectral and spatial intensity distributions of light sources, is described. With this technique projections of an intensity distribution of the source o(x, y, lambda) onto the xy plane are detected simultaneously, and the original distribution is numerically reconstructed from them by using an algorithm of computed tomography. Five projections are obtained experimentally as shared images by means of an imaging system equipped with a transmission grating and detected by a monochromatic television camera. The spatial and spectral distributions of the objects are reconstructed with the multiplicative algebraic reconstruction technique.
Single Molecule Fluorescence under Conditions of Fast Flow (2011)

We have experimentally determined the optimal flow velocities to characterize or count single molecules by using a simple microfluidic device to perform two-color coincidence detection (TCCD) and single pair Förster resonance energy transfer (spFRET) using confocal fluorescence spectroscopy on molecules traveling at speeds of up to 10 cm s(-1). We show that flowing single fluorophores at ≥0.5 cm s(-1) reduces the photophysical processes competing with fluorescence, enabling the use of high excitation irradiances to partially compensate for the short residence time within the confocal volume (10-200 μs). Under these conditions, the data acquisition rate can be increased by a maximum of 38-fold using TCCD at 5 cm s(-1) or 18-fold using spFRET at 2 cm s(-1), when compared with diffusion. While structural characterization requires more photons to be collected per event and so necessitates the use of slower speeds (2 cm s(-1) for TCCD and 1 cm s(-1) for spFRET), a considerable enhancement in the event rate could still be obtained (33-fold for TCCD and 16-fold for spFRET). Using flow under optimized conditions, analytes could be rapidly quantified over a dynamic range of up to 4 orders of magnitude by direct molecule counting; a 50 fM dual-labeled model sample can be detected with 99.5% statistical confidence in around 8 s using TCCD and a flow velocity of 5 cm s(-1).

Calcium and wound healing in Xenopus early embryos. (1982)

The role of calcium in the healing of wounds made in the ectoderm of Xenopus neurulae has been studied. Embryos have been wounded in the presence of calcium inhibitors, and the effects on wound healing observed by scanning electron microscopy. In addition, unwounded embryos have been exposed to a local application of ionophore A23187 to simulate the possible calcium fluxes following wounding. Lanthanum, which competes for calcium channels, inhibits wound healing. EDTA, which binds divalent cations, also inhibits wound healing, but its effect can be reversed by the addition of excess calcium. Local application of ionophore A23187, which promotes transport of calcium across biological membranes, results in a local change in cell shapes. These observations lend support to the hypothesis that wound healing in amphibian early embryos, which is effected by changes in cell shapes similar to those seen in certain examples of normal morphogenesis, is initiated by a local influx of calcium into cells.
Electrical property improvement of electrically conductive adhesives through in-situ replacement by short-chain difunctional acids (2006)

To improve the electrical properties of electrically conductive adhesives (ECAs), short-chain difunctional acids, such as malonic acid (acid M), adipic acid (acid A), and terephthalic acid (acid T) were introduced into a typical isotropic conductive adhesive formulation. By in-situ replacement of the commonly used surfactant-stearic acid in silver(Ag) flakes, such difunctional acids can increase the conductivity of ECAs. With the addition of malonic acid and adipic acid, which only have short chain single-bond hydrocarbon between the dicarboxylic groups, the conductivity of the typical conductive adhesives was improved significantly. Terephthalic acid, however, deteriorates the conductivity due to the rigid aromatic structure in the molecule. Dynamic mechanical analysis and thermomechanical study indicated the improved electrical properties with malonic and adipic acids were achieved without negatively affecting the mechanical and physical properties of ECAs.
VISCOELASTIC PROPERTIES OF HEAT‐SET WHEY PROTEIN EMULSION GELS (1998)

ABSTRACT The viscoelastic properties of heat‐set whey protein gels and whey protein‐stabilized emulsion gels have been studied using the dynamic oscillatory rheometry technique. The storage modulus was monitored and analysed for pure protein gels and emulsion gels over a wide range of protein concentrations. The dependence of storage modulus on protein concentration is different for gels of low and high modulus. At low protein concentrations, the increase of storage modulus is much more sensitive to the increase of protein concentration. The protein‐coated oil droplets behave as active filler particles and dramatically enhance the gel strength. The effect of the oil volume fraction on the rheology has been investigated for emulsion gels containing 11 vol. %, 20 vol. % and 45 vol. % Trisun oil. The formula of van der Poel fails to describe the experimental results. This is attributed to the strongly flocculated state of the emulsion system.
The polytopic mitochondrial inner membrane proteins MIM17 and MIM23 operate at the same preprotein import site (1994)

Three proteins of the mitochondrial inner membrane are known that are essential for the viability of yeast and seem to be involved in import of preproteins; the integral membrane proteins MIM17 and MIM23 and the peripheral membrane protein MIM44, MIM17 and MIM23 are homologous to each other in their hydrophobic domain, expose their termini to the intermembrane space, and span the inner membrane up to four times, each. A preprotein in transit across the mitochondrial membrane is specifically cross-linked to MIM17, MIM23, MIM44, and matrix hsp70. We conclude that MIM17 and MIM23 are integral parts of a preprotein translocation channel and cooperate with MIM44 and hsp70 at the same protein import site.
Current status of counterpulsation in cardiac assistance: a summary of experimental experience in the dog. (1966)

Synchronized counterpulsation was applied to two groups of nine dogs using a new fluid-coupled pulse generator. Pump performance and synchronization were superior to earlier pneumatic systems. Improvement in cardiac function was evidenced by reduction in left ventricular pressure, work and oxygen consumption. Peripheral hemodynamics were adversely affected as evidenced by reduction in blood pressure, cardiac output, renal and carotid blood flows and decrease in central venous oxygen saturation. Evaluation of counterpulsation in acute left ventricular failure produced in 15 dogs by serial coronary ligations revealed that the elevated left atrial pressure was reduced, but neither cardiac output nor arterial pressure was improved by counterpulsation.
Adoptive transfer of murine cytomegalovirus-immune lymph node cells prevents retinitis in T-cell-depleted mice. (1997)

Adoptive immunotherapy has been used to prevent cytomegalovirus (CMV) infection in patients who have undergone transplantation, and, by extrapolation, the results of these studies suggest that adoptive immunotherapy with human CMV-specific immune cells might be used to prevent or ameliorate CMV retinitis in immunocompromised patients.
Bicaudal D Family Adaptor Proteins Control the Velocity of Dynein-Based Movements (2014)

Cargo transport along microtubules is driven by the collective function of microtubule plus- and minus-end-directed motors (kinesins and dyneins). How the velocity of cargo transport is driven by opposing teams of motors is still poorly understood. Here, we combined inducible recruitment of motors and adaptors to Rab6 secretory vesicles with detailed tracking of vesicle movements to investigate how changes in the transport machinery affect vesicle motility. We find that the velocities of kinesin-based vesicle movements are slower and more homogeneous than those of dynein-based movements. We also find that Bicaudal D (BICD) adaptor proteins can regulate dynein-based vesicle motility. BICD-related protein 1 (BICDR-1) accelerates minus-end-directed vesicle movements and affects Rab6 vesicle distribution. These changes are accompanied by reduced axonal outgrowth in neurons, supporting their physiological importance. Our study suggests that adaptor proteins can modulate the velocity of dynein-based motility and thereby control the distribution of transport carriers.
3D Structure extraction with omnidirectional and perspective cameras (2010)

The work presented here is on extraction of 3D structure using images of different camera types. For systems with one type of camera, a common way of structure extraction is matching and computing the camera motion between the views, and estimating the 3D location of the points in the scene. Our contribution is proposing and bringing together proper methods to effectively apply this approach with images of perspective and omnidirectional cameras together. We present the results of our experiment performed using the images of a hybrid camera system.
