Self-Care of Adults With Non-Insulin-Dependent Diabetes Mellitus: Influence of Family and Friends (1996)

This study examined the relationships among the source of support, universal self-care, and health-deviation self-care behaviors in adults who control their blood glucose with oral agents. A descriptive correlational design was used. Respondents completed a total of 51 items on questionnaires. Significant differences were found between the group with family-plus-friend support and the group without support in relation to universal self-care and health-deviation self-care. A significant difference was also found between the group with family-plus-diabetes-group support and the group without support in relation to health-deviation self-care. Subjects who received support from friends in addition to family support reported higher universal and health-deviation self-care behaviors than those without support. Support systems explained 23% of variance in universal self-care and 17% of variance in health-deviation self-care.
Effective medium theory of light scattering in polymer dispersed liquid crystal films (1998)

We present calculations of the optical properties of PDLC films subjected to normally incident unpolarized light, in the long-wavelength regime under which the Rayleigh-Gans approximation applies. The calculations use an effective medium theory to take account of dependent scattering effects due to close packing of droplets, and use the Percus-Yevick approximation for hard spheres to account for interference effects. The director configurations inside the droplets are found using the effective medium theory which we have developed in earlier papers. Typical results are presented for radial and bipolar droplets. Detailed quantitative results have been derived for the optical characteristics in the presence of an applied field for the technologically important case of PDLC films containing partially ordered bipolar droplets.
Anaerobic growth of Salmonella typhimurium results in increased uptake by Henle 407 epithelial and mouse peritoneal cells in vitro and repression of a major outer membrane protein (1991)

The growth of Salmonella typhimurium under anaerobic conditions resulted in its greater ability to invade Henle 407 epithelial cells and in greater uptake by mouse peritoneal cells in vitro. Anaerobic growth also resulted in the repression of at least one major outer membrane protein.
Learning-based power prediction for data centre operations via deep neural networks (2016)

Modelling and analyzing power consumption for data centres can diagnose potential energy-hungry components and applications, and facilitate in-time control, benefiting the energy efficiency of data centers. However, solutions to this problem, including static power models and canonical prediction models, either aim to build a static relationship between power consumption and hardware/application configurations without considering the dynamic fluctuation of power; or simply treat it as time series, ignoring the inherit power data characteristics. To tackle these issues, in this paper, we present a systematic power prediction framework based on extensive power dynamic profiling and deep learning models. In particular, we first analyse different power series samples to illustrate their noise patterns; accordingly we propose a power data de-noising method, which lowers noise interference to the modelling. With the pretreated data, we propose two deep learning based prediction models, including a fine-grained model and a coarse-grained model, which are suitable for different time scales. In the fine-grained prediction model, a recursive autoencoder (AE) is employed for short-duration prediction; in the coarse-grained model, an AE is used to encode massive fine-grained historical data as a further data pretreatment for long-duration prediction. Experimental results show that our proposed models outperform canonical prediction methods with higher accuracy, up to 79% error reduction for certain cases.
Analyzing Business Processes by Automatically Detecting KPI Thresholds (2016)

This paper describes a method for automatically detecting key performance indicator (KPI) thresholds by dividing and aggregating process instances on the basis of differences in process models. The thresholds can be used as an analysis axis of data exploration to investigate process models that are discovered from huge logs. The proposed method enables users to minimize the time needed to detect KPI thresholds through trial and error. We applied the method to real-life logs and experiment results showed that thresholds were detected for two types of KPIs. Although one type did not correlate with process patterns, the other highly correlated with them. Such findings are usually obtained from the domain knowledge of business users and analysis results acquired by data analysts with technical expertise. However, with our approach the thresholds can be detected automatically and this helps to expand process analysis for end users.
Inverted Colloidal Crystals as Three-Dimensional Cell Scaffolds (2004)

A new type of three-dimensional scaffold with inverted colloidal crystal geometry for the investigation of topological effects in cell cultures is introduced in this publication. The scaffolds are made by infiltration of the hexagonal crystal lattice of polystyrene spheres with sol-gel formulation and subsequent annealing. It possesses a relatively high degree of order among existing cell scaffolds and affords tight control over the scaffold porosity and tissue organization. The prepared scaffolds can be a convenient system for the investigation of cell-cell and cell-matrix interactions. Their biocompatibility is demonstrated for human hepatocellular carcinoma HEP G2 and human bone marrow HS-5 cell cultures. A preliminary effect of the scaffold topology on cell proliferation is observed. HEP G2 hepatocytes form a large number of 10-15 cell colonies on scaffolds made from 75-microm spheres, while their number diminishes for scaffolds from 10- and 160-microm spheres. Under similar conditions, HS-5 forms smaller colonies consisting of three to four cells in 90-microm cavities.
Reduced suppressive effect of β2-adrenoceptor agonist on fibrocyte function in severe asthma (2017)

Fibrocytes from patients with severe asthma are relatively insensitive to the inhibitory effects of salmeterol, an effect which is reversed by combination with corticosteroids.
Volumetric ellipsoid zone mapping for enhanced visualisation of outer retinal integrity with optical coherence tomography (2015)

Objective assessment of retinal layer integrity with optical coherence tomography (OCT) is currently limited. The ellipsoid zone (EZ) has been identified as an important feature on OCT that has critical prognostic value in macular disorders. In this report, we describe a novel assessment tool for EZ integrity that provides visual and quantitative assessment across an OCT data set. Using this algorithm, we describe the findings in multiple clinical examples, including normal controls, age-related macular degeneration, drug effects (eg, ocriplasmin, hydroxychloroquine) and effects of surgical manipulation (eg, following membrane peeling using intraoperative OCT). EZ mapping provides both en face visualisation of EZ integrity and EZ-retinal pigment epithelium height. Additionally, volumetric, area and linear measurements are feasible using this assessment tool.
Fabrication of optical strip waveguides with nearly circular cross section by silver ion migration technique (1980)

Circular optical waveguides have been fabricated from vacuum-deposited Ag layers by ion migration technique into soda-lime substrate glass. In this method two different guide patterns, one of which is the mirror image of the other, are made. Later the guide patterns are placed on top of each other and circular guides are thus obtained. The ends of the guides are studied by optical microscope and the near-field scanning method. The optical loss spectrum is measured from 450 to 1600 nm.
Growth Curve Modeling and Longitudinal Factor Analysis (2015)

Abstract In psychological science, developmentalists are often interested in examining and understanding change processes. In this chapter we review a variety of longitudinal models and consider how they can be applied to examine intraindividual change and interindividual differences in change. First, a taxonomy describing three types of change processes (incremental change processes, transformational change processes, and stability‐maintenance processes) is presented and how a selection of contemporary longitudinal models can be tethered to that taxonomy is considered. A selection of growth models–with emphasis on models that are used to describe nonlinear trajectories–is reviewed and a shift toward the use of differential equations is suggested. A selection of time‐series models is shown, with emphasis on models that may facilitate analysis of the big data streams that will become available in few years. Although the distinctions among types of change processes and among analytical frameworks are necessarily fuzzy, the hope is that by explicitly discussing the analytical methods as abstract representations of core aspects of change, researchers will be able to select study designs and analytical procedures that map to and more precisely test their theories of change. The chapter finishes with some notes on implementation, with encouragement for further consideration of nonlinearity, to measure more frequently, and to label parameters with theoretically meaningful names.
The coagulant-active phospholipid content is a major determinant of in vivo thrombogenicity of prothrombin complex (Factor IX) concentrates in rabbits (1982)

In vitro evaluation of prothrombin complex concentrates in a thrombin generation assay, using DAPA and purified components of the prothrombinase complex, demonstrated significant levels of coagulant- active “phospholipid replacing” activity. Quantification of this activity showed a significant correlation (r = 0.8747, p less than 0.01) with thrombogenicity measured in vivo in a stasis model in rabbits. Extracted lipid material retained full phospholipid replacing activity in the vitro assay. Thin-layer chromatographic characterization confirmed the presence of phospholipids with known coagulant activity in vitro. In vivo, the extracted material was nonthrombogenic but augmented the thrombogenicity of purified factor Xa. Substitution of a synthetic coagulant-active phospholipid (phosphatidylcholine-phosphatidylserine lipid vesicles) for the extracted phospholipid produced a similar augmentation of a factor-Xa- induced thrombogenicity in vivo. It is concluded that the coagulant- active phospholipid content of prothrombin complex concentrates is a major determinant of thrombogenicity but requires the presence of activated clotting factors for its expression in vivo.
Properties of LYSO and recent LSO scintillators for phoswich PET detectors (2004)

The luminescence and nuclear spectroscopic properties of the new cerium-doped rare-earth scintillator lutetium-yttrium oxyorthosilicate (Lu/sub 0.6/Y/sub 1.4/Si/sub 0.5/:Ce, LYSO) were investigated and compared to those of both recent and older LSO crystals. UV-excited luminescent spectra outline important similarities between LYSO and LSO scintillators. The two distinct Ce1 and Ce2 luminescence mechanisms previously identified in LSO are also present in LYSO scintillators. The energy and timing resolutions were measured using avalanche photodiode (APD) and photomultiplier tube (PMT) readouts. The dependence of energy resolution on gamma-ray energy was also assessed to unveil the crystal intrinsic resolution parameters. In spite of significant progress in light output and luminescence properties, the energy resolution of these scintillators appears to still suffer from an excess variance in the number of scintillation photons. Pulse-shape discrimination between LYSO and LSO scintillators has been successfully achieved in phoswich assemblies, confirming LYSO, with a sufficient amount of yttrium to modify the decay time, to be a potential candidate for depth-of-interaction determination in multicrystal PET detectors.
Relationship Between Spontaneous and Evoked Spike-Time Correlations in Primate Visual Cortex (2009)

Coincident spikes have been implicated in vision-related processes such as feature binding, gain modulation, and long-distance communication. The source of these spike-time correlations is unknown. Although several studies have proposed that cortical spikes are correlated based on stimulus structure, others have suggested that spike-time correlations reflect ongoing cortical activity present even in the absence of a coherent visual stimulus. To examine this issue, we collected single-unit recordings from primary visual cortex (V1) of the anesthetized and paralyzed prosimian bush baby using a 100-electrode array. Spike-time correlations for pairs of cells were compared under three conditions: a moving grating at the cells' preferred orientation, an equiluminant blank screen, and a dark condition with eyes covered. The amplitudes, lags, and widths of cross-correlation histograms (CCHs) were strongly correlated between these conditions although for the blank stimulus and dark condition, the CCHs were broader with peaks lower in amplitude. In both preferred stimulus and blank conditions, the CCH amplitudes were greater when the cells within the pair had overlapping receptive fields and preferred similar orientations rather than nonoverlapping receptive fields and different orientations. These data suggest that spike-time correlations present in evoked activity are generated by mechanisms common to those operating in spontaneous conditions.
Characterization of mouse thrombospondin 2 sequence and expression during cell growth and development. (1992)

Thrombospondin (TSP) is an extracellular matrix glycoprotein whose expression has been associated with a variety of cellular processes including growth and embryogenesis. The recent discovery of the existence of a second mouse TSP gene necessitates careful examination of the discrete biochemical and functional properties associated with each molecule. In this report, the primary structures of human TSP, mouse TSP1 (mTSP1), mouse TSP2 (mTSP2), and chicken TSP are compared; and the expression of mTSP1 and mTSP2 during embryogenesis and growth factor-mediated cell proliferation is examined. The cloning and sequencing of the entire coding regions of mTSP1 and mTSP2 revealed considerable conservation of residues critical for TSP structure and function; these data suggest that TSP2 is capable of trimer formation and many of the same cell-surface and ligand interactions that mediate TSP function. Comparison of the various TSP sequences also allowed the assignment based on sequence homology of previously reported human TSP as TSP1 and chicken TSP as TSP2. mTSP2, like mTSP1, was shown to be a primary response gene when quiescent Swiss 3T3 cells were stimulated with serum, platelet-derived growth factor BB, basic fibroblast growth factor, or interleukin-1 beta. Interestingly, TSP1 and TSP2 exhibited markedly different tissue- and stage-specific patterns of mRNA expression during mouse embryogenesis, implying that the two TSP molecules possess discrete functional properties important for development. Additionally, the TSP genes (Thbs1 and Thbs2) were mapped to single loci on mouse chromosomes 2 and 17, respectively.
Automatic detection of facial feature points and contours (2002)

This paper presents a method for automatic processing of human faces from color images. We describe a new system, which works hierarchically from detecting the position of human faces and their features (such as eyes, nose, mouth, etc.) and to extracting their contours and feature points. The position of human faces and their parts are detected from the image by applying the integral projection method, which uses both the color information (skin and hair color) and edge information (intensity and sign). A multiple active contour model is used to extract the contour-lines of facial features. To do this, we use color information in their energy terms. Facial feature points are decided based on the optimized contours. A constructed 3D facial model using these points can be used to generate its facial expression or change its view. The proposed system is confirmed to be very effective and robust when dealing with images of faces with complex backgrounds.
Gas phase temperature measurements in a flame spray pyrolysis process by O2 pure rotational CARS (2012)

For the production of oxide nanoparticles at a commercial scale, flame spray processes are frequently used. To preserve the original behavior of the sensitive flame spray pyrolysis process in situ, the gas phase temperatures were measured with pure rotational CARS. An O2 pure rotational CARS setup was applied due to the lack of N2. The CARS technique benefit from a polarization filtering technique that is essential in particle and droplet environments for acquiring CARS spectra suitable for temperature fitting. The temperature results indicate the dissipation of energy by radiation in the presence of particles since the flame temperatures are decreasing with increasing particle concentrations.
Phenyltetrahydroisoquinoline–Pyridinaldoxime Conjugates as Efficient Uncharged Reactivators for the Dephosphylation of Inhibited Human Acetylcholinesterase (2012)

Pyridinium and bis-pyridinium aldoximes are used as antidotes to reactivate acetylcholinesterase (AChE) inhibited by organophosphorus nerve agents. Herein, we described a series of nine nonquaternary phenyltetrahydroisoquinoline-pyridinaldoxime conjugates more efficient than or as efficient as pyridinium oximes to reactivate VX-, tabun- and ethyl paraoxon-inhibited human AChE. This study explores the structure-activity relationships of this new family of reactivators and shows that 1b-d are uncharged hAChE reactivators with a broad spectrum.
Optical Separation of Racemic Ketoprofen by Chiral High-Performance Liquid Chromatography (2001)

Ketoprofen, a phenylpropionic acid derivative, is a non-steroidal anti-inflammatory drug(NSAID) that has anal- gesic, anti-inflammatory and antipyretic properties. Pharmacological activity has been attributed mainly to the S-(+)-enanti- omer, while the R-(-)-enantiomer is either inactive or has side effect. The optical separation of Ketoprofen enantiomers was carried out by various chiral HPLC(chiral high-performance liquid chromatography) columns and most compatible separation conditions of Ketoprofen enantiomers were investigated. The resolution and enantio selectivity of Ketoprofen were found to be strongly influenced by the employed chiral stationary phases(CSPs) and composition of eluents. The employed chiral station- ary phases(CSPs) in this study were β-CD BR ® and Kromasil ® . The optimum composition of eluent was obtained differently for stationary material phase. The effects of process variables such as flow rate, injection volume, and concentration of eluent on Ketoprofen enantiomers separation were investigated using Kromasil ® columns. The resolution decreased with the increase of
Feasibility study on 16 μm continuous-wave modulation laser absorption spectrometer system for measurement of global CO_2concentration from a satellite (2011)

A feasibility study is carried out on a 1.6 μm continuous-wave modulation laser absorption spectrometer system for measurement of global CO(2)concentration from a satellite. The studies are performed for wavelength selection and both systematic and random error analyses. The systematic error in the differential absorption optical depth (DAOD) is mainly caused by the temperature estimation error, surface pressure estimation error, altitude estimation error, and ON wavelength instability. The systematic errors caused by unwanted backscattering from background aerosols and dust aerosols can be reduced to less than 0.26% by using a modulation frequency of around 200 kHz, when backscatter coefficients of these unwanted backscattering have a simple profile on altitude. The influence of backscattering from cirrus clouds is much larger than that of dust aerosols. The transmission power required to reduce the random error in the DAOD to 0.26% is determined by the signal-to-noise ratio and the carrier-to-noise ratio calculations. For a satellite altitude of 400 km and receiving aperture diameter of 1 m, the required transmission power is approximately 18 W and 70 W when albedo is 0.31 and 0.08, respectively; the total measurement time in this case is 4 s, which corresponds to a horizontal resolution of 28 km.
Bayesian Generation and Integration of K-nearest-neighbor Patterns for 19x19 Go. (2005)

Abstract- This paper describes the generation and utilisation of a pattern database for 19x19 go with the Knearest-neighbor representation. Patterns are generated by browsing recorded games of professional players. Meanwhile, their matching and playing probabilities are estimated. The database created is then integrated into an existing go program, INDIGO, either as an opening book or as an enrichment of other pre-existing hand-crafted databases used by INDIGO move generator. The improvement brought about by the use of this pattern database is estimated at 15 points on average, which is significant on go standards. 1
PROPOSED SOLUTIONS TO THE FREIGHT CAR TRUCK PROBLEMS OF FLANGE WEAR AND TRUCK HUNTING (1975)

This paper reports on the progress of a development program whose objective is to devise cost effective solutions to the problems of excessive flange wear and truck hunting. It is expected that later papers will deal with separate aspects of this program in greater detail. Three solutions for freight cars are proposed: (1) a retrofit steering assembly kit for application to the trucks of existing roller bearing cars, (2) modification of the side frame and bolster castings to incorporate a more cost effective steering assembly for new trucks and (3) a completely new truck design incorporating improvements in car suspension as well. All three designs include a steering feature which will reduce wheel and rail wear in curves and elminate truck hunting. The second and third designs also provide better brake shoe/wheel alignment for additional savings in wheel wear. The appendices define the terminology used and identify the design characteristics of conventional trucks which lead to the present high cost of ownership.
Studies on Limulus amoebocyte lysate II. Purification of the coagulogen and the mechanism of clotting. (1977)

A coagulogen in Limulus lysate has been purified to apparent homogeneity as judged by sodium dodecyl sulfate-gel electrophoresis. The purified coagulogen identified by its ability to clot with either trypsin or the purified Limulus clotting enzyme (Tai, J.Y., and Liu, T. Y. (1976) Fed. Proc. 35, 1486) has a molecular weight of 24,500. It consists of a single polypeptide chain of about 220 amino acids with glycine and serine as its NH2- and COOH-terminal residues; respectively. When acted upon by the Limulus clotting enzyme, the coagulogen releases a soluble C-peptide of about 45 amino acids and an insoluble coagulin of about 170 amino acids. The latter interacts in a noncovalent fashion to form the clot. Amino acid analyses together with the results of NH2- and COOH-terminal analyses suggest that the clot formation involves the cleavage of an--Arg--Lys--bond. Trypsin acts on the coagulogen to cause clotting by splitting the same peptide bond.
