Abuse prevention of street camera network by browsing-history disclosure (2015)

Summary form only given. Street camera network, in which many street cameras are installed at high density just like street lights throughout the nation, will have a stronger positive effect in suspect tracking and crime deterrence in the near future. On the other hand, it will also have a stronger negative possibility in violation of privacy of ordinary citizen. It is necessary for such a stronger surveillance camera system, which forcibly captures the images of passers for the public interest, to be accepted as an essential social infrastructure by the society, that only the usage for the public interest, which is accepted by the society beforehand, is possible and this can be believed by the ordinary citizen. To realize this, a new concept, in which abuse of street camera network is deterred by browsing-history disclosure, is proposed. In the lecture, the concept, the prototype and the experiment will be reported and the future prospect will also be presented.
Ginna Station steam generator U-bend tube analysis for chemical cleaning data (1992)

This report discusses a potential cause of the decrease in steam pressure affecting many nuclear plant recirculating steam generators which is the buildup of deposit on the outside surfaces of the tubing. This deposit layer, if thick enough, acts to insulate'' the tube, resulting in decreased heat transfer from the reactor coolant to the secondary fluid. At some point in time, fouling may thus degrade thermal performance to a level that warrants chemical cleaning of the steam generators. To help in evaluating the extent and effect of deposit buildup in Rochester Gas Electric's (RGE) Ginna Plant steam generators, sections of one outer row Unbend tube were removed. The tube specimens were examined and tested to: (1) determine the deposit morphology (density, thickness, composition); (2) determine the effect of the deposit on the overall heat transfer coefficients; and (3) obtain the basic solubility and dissolution data needed to chemically clean the tube sections. Results of the laboratory examination and test program indicate that the deposit in the U-bend area is a duplex scale approximately 8--9 mils thick. The inner layer ({approximately}2 mils thick) is relatively non-porous and is composed primarily of calcium, phosphorous, and oxygen resulting from the plant's initial usemore » of a phosphate based water treatment program. The outer layer is primarily magnetite with copper particles dispersed throughout. Bench scale tests confirmed that the solubility of the deposit in the EPRI/SGOG solvents is high ({approximately}98 %) with excellent dissolution kinetics. Heat transfer tests performed at prototypical steam generator pressures and temperatures and at nucleate boiling conditions indicate that the overall heat transfer coefficient of the tube specimens increased by {approximately}34 % when the deposit was removed with the EPRI/SGOG chemical cleaning process.« less
A Conceptual Analysis of Equilibrium Bidding Strategy in a Combined Oligopoly and Oligopsony Wholesale Electricity Market (2022)

This paper proposes a semi-analytical method to obtain the equilibrium bidding strategies for generation and demand units in a <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">combined</i> oligopoly and oligopsony wholesale electricity market. Such market structure is the outcome of the increasing deployment of demand response programs that facilitate <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">active participation of demand-side players</i> in the price-setting process. In this analysis, the concept of supply function equilibrium (SFE) is used to investigate the oligopolistic competition among generation units. The SFE model is extended and the demand function equilibrium (DFE) is obtained to study the oligopsonistic competition among demand units. The economic behavior of a market participant is formulated as a bi-level programming (BLP) problem. The <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">imperfect competition</i> among generation units, as well as among demand units, are modeled as a non-cooperative game. Next, a direct method is developed to calculate all candidate equilibriums of the market, and the locational marginal prices (LMPs) in terms of the bidding strategies of the market participants. The BLP problem is solved by obtaining the coordinated Pareto-dominant Nash equilibrium of the market participants’ non-cooperative games. Finally, the proposed analysis is examined in case studies. Accordingly, we report <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">insightful observations</i> with respect to the impact of the changes in the new market structure, at firm-level and market-level, such as in terms of mitigating market power of generation units, the market clearing prices and quantities, surplus for generation units and demand units, and potential impact on market efficiency.
Abstract 17861: Injectable Shear-thinning Hydrogels to Deliver Endothelial Progenitor Cells, Reduce Ventricular Strain, and Dynamic Stiffness to Stabilize Cardiac Function Following Ischemic Injury (2015)

The ventricle undergoes adverse remodeling, post-infarction. We developed an injectable shear-thinning hyaluronic acid hydrogel(STG) and endothelial progenitor cell construct(STG-EPC) to enhance vasculogenesis(shown previously) and mechanically stabilize the infarcted myocardium. We hypothesize that this tissue-engineered therapy will minimize adverse remodeling and maintain myocardial tensile properties in a clinically translatable therapy. EPCs(DiLDL+ VEGFR2+ CD34+) were harvested from adult Wistar Rats and suspended in STG. STG-EPC constructs were circumferentially injected at the borderzone of ischemic rat myocardium, following LAD ligation. Engraftment and retention were assessed by near infrared cellular tag. Myocardial remodeling, tensile properties, and hemodynamic function were analyzed in 4 groups: control(PBS), EPC injection(EPC), STG injection(STG), and STG-EPC construct(STG-EPC). High-resolution ultrasound with speckle tracking (VSI Vevo 2100) allowed analysis of regional epicardial and endocardial strain. Uniaxial testing assessed tensile strength. STG-EPC injection significantly increased engraftment, migration, and retention of the EPCs one-week post implant compared to EPC (0.7 vs 0.4 RFU, p=0.02). Using strain echocardiography a significant increase in left ventricular function was noted in the STG-EPC cohort. Strain echocardiography examination revealed a significant retention of myocardial longitudinal displacement with subsequent stabilization of myocardial velocity with STG-EPC therapy. A reduction in dynamic stiffness was noted in the STG-EPC cohort.(Table) This novel injectable shear-thinning hyaluronic acid hydrogel seeded with EPCs demonstrates stabilization of borderzone myocardium with reduction in adverse myocardial remodeling and preservation of myocardial biomechanics. There is a markedly increased retention of delivered stem cells with this tissue engineered therapy.
Somatic Cells Efficiently Join Unrelated DNA Segments End-to-End (1982)

Molecular substrates for probing nonhomologous recombination in somatic cells were constructed by inserting pBR322 sequences at selected sites on the simian virus 40 (SV40) genome. The chimeric products are too large to be packaged into an SV40 capsid. Therefore, production of viable progeny requires that most of the pBR322 sequences be deleted without altering any SV40 sequences that are essential for lytic infection. As judged by plaque assay, these recombination events occur at readily detectable frequencies after transfection into CV1 monkey kidney cells. Depending on the site of pBR322 insertion, the infectivities of the full-length circular or linear chimeras ranged from 0.02 to 2% of the infectivity of linear wild-type SV40 DNA. Nucleotide sequence analysis of several recombinant progeny revealed three distinct classes of recombination junction and indicated that the causative recombination events were minimally dependent on sequence homology. Potential mechanisms involving recombination at internal sites or at ends were distinguished by measuring the infectivity of chimeric molecules from which various lengths of pBR322 had been removed. These data support end-to-end joining as the primary mechanism by which DNA segments recombine nonhomologously in somatic cells. This end joining appears to be very efficient, since SV40 genomes with complementary single-stranded tails or with short non-complementary pBR322 tails were comparably infectious. Overall, this study indicates that mammalian somatic cells are quite efficient at the willy-nilly end-to-end joining of unrelated DNA segments.
A Novel Family 8 Xylanase, Functional and Physicochemical Characterization (2002)

Xylanases are generally classified into glycosyl hydrolase families 10 and 11 and are found to frequently have an inverse relationship between their pI and molecular mass values. However, we have isolated a psychrophilic xylanase that belongs to family 8 and which has both a high pI and high molecular mass. This novel xylanase, isolated from the Antarctic bacterium Pseudoalteromonas haloplanktis, is not homologous to family 10 or 11 enzymes but has 20-30% identity with family 8 members. NMR analysis shows that this enzyme hydrolyzes with inversion of anomeric configuration, in contrast to other known xylanases which are retaining. No cellulase, chitosanase or lichenase activity was detected. It appears to be functionally similar to family 11 xylanases. It hydrolyzes xylan to principally xylotriose and xylotetraose and is most active on long chain xylo-oligosaccharides. Kinetic studies indicate that it has a large substrate binding cleft, containing at least six xylose-binding subsites. Typical psychrophilic characteristics of a high catalytic activity at low temperatures and low thermal stability are observed. An evolutionary tree of family 8 enzymes revealed the presence of six distinct clusters. Indeed classification in family 8 would suggest an (alpha/alpha)(6) fold, distinct from that of other currently known xylanases.
An Unprecedented Charge Transfer Induced Spin Transition in an Fe–Os Cluster (2010)

High 'n low: The novel {[Fe(tmphen)2]3[Os(CN)6]2} complex (see structure) is the first example of a cluster in which a high-spin FeIII ion is in a coordination environment of four imine nitrogen atoms and two N-coordinated cyanides. Magnetic studies reveal an unprecedented type of reversible charge transfer induced spin transition (CTIST) between the low-spin FeIINCOsIII and high-spin FeIIINCOsII systems.
Data Analysis for a Dual-Channel Virus Counter (2005)

A simple algorithm is presented for quantitative analysis of simultaneous events on a dual-channel flow cytometer designed specifically for virus counting. The algorithm, which is based on matrix analysis of burst lag times, was evaluated using baculovirus samples that had previously been quantified by the plaque titer method. The results indicated statistical reliability for the algorithm, with three of six samples yielding the same value, within error, for viruses per unit volume as the plaque titer. The other three samples yielded values within a factor approximately 2, which was deemed acceptable given the limitations of the plaque titer method.
Detection and Coding of Edges Using Directional Masks (1977)

This paper describes a new image coding system which combines the detection and coding of visually significant edges in natural images. The edges are defined as amplitude discontinuities between different regions of an image. The edge detection system makes use of 3 x 3 masks, which are well suited for digital implementation. Edge angles are quantized to eight equally spaced directions, suitable for chain coding of contours. Use of an edge direction map improves the simple thresholding of gradient modulus images. The concept of local connectivity of the edge direction map is useful in improving the performance of this method as well as other edge operators such as Kirsch and Sobel. The concepts of an "edge activity index" and a "locally adaptive threshold" are introduced and shown to improve the performance even further.
Low-Energy Ion-Induced Electron Emission from a MgO(100) Thin Film: The Role of the MgO-Substrate Interface (2002)

We present a detailed study of the electron emission from a thin MgO(100) film on a Mo substrate, bombarded with slow He+, Ne+, and Ar+ ions. Neither the high absolute number of emitted electrons per incoming ion nor the electron spectra can be due to Auger neutralization of the incoming ions at the MgO surface alone. Therefore, an additional mechanism is proposed: holes created in the MgO film are transported to the MgO-substrate interface where they give rise to an Auger neutralization process involving two electrons from the metal substrate conduction band.
Enhanced electron attachment to laser-irradiated molecular hydrogen (1992)

Filgrastim and topneuter demonstrate no statistically significant difference in either HSC mobilization kinetics of peripheral and bone marrow blood or hematopoietic reconstitution. Topneuter can be a reliable agent for donor HSC mobilization and recipient hematopoietic reconstitution following allo-HSCT.
Total cost estimation for implementing genome-enabled selection in a multi-level swine production system (2014)

By modifying the input values, such as herd size and genotyping strategy, a flexible spreadsheet tool developed from this work can be used to estimate the additional costs associated with genome-enabled selection. This tool will aid breeders in estimating the economic viability of incorporating genome-enabled selection into their specific breeding program.
Parallel query processing in shared disk database systems (1993)

System developments and research on parallel query processing have concentrated either on “Shared Everything” or “Shared Nothing” architectures so far. While there are several commercial DBMS based on the “Shared Disk” alternative, this architecture has received very little attention with respect to parallel query processing. A comparison between Shared Disk and Shared Nothing reveals many potential benefits for Shared Disk with respect to parallel query processing. In particular, Shared Disk supports more flexible control over the communication overhead for intra-transaction parallelism, and a higher potential for dynamic load balancing and efficient processing of mixed OLTP/query workloads. We also sketch necessary extensions for transaction management (concurrency/coherency control, logging/recovery) to support intra-transaction parallelism in the Shared Disk environment.
Probabilistic 3D Human Shape and Pose Estimation from Multiple Unconstrained Images in the Wild (2021)

This paper addresses the problem of 3D human body shape and pose estimation from RGB images. Recent progress in this field has focused on single images, video or multi-view images as inputs. In contrast, we propose a new task: shape and pose estimation from a group of multiple images of a human subject, without constraints on subject pose, camera viewpoint or background conditions between images in the group. Our solution to this task predicts distributions over SMPL body shape and pose parameters conditioned on the input images in the group. We probabilistically combine predicted body shape distributions from each image to obtain a final multi-image shape prediction. We show that the additional body shape information present in multi-image input groups improves 3D human shape estimation metrics compared to single-image inputs on the SSP-3D dataset and a private dataset of tape-measured humans. In addition, predicting distributions over 3D bodies allows us to quantify pose prediction uncertainty, which is useful when faced with challenging input images with significant occlusion. Our method demonstrates meaningful pose uncertainty on the 3DPW dataset and is competitive with the state-of-the-art in terms of pose estimation metrics.
Clinical response to regional intravenous guanethidine in patients with rheumatoid arthritis. (1986)

A novel therapy for rheumatoid arthritis, regional sympathetic blockade using guanethidine, was investigated in 24 patients with active disease. In a randomized double blind short-term (14 days) study, we evaluated the effect of therapy on subjective responses, change in pain, stiffness, and morning stiffness and no objective responses, change in pinch strength, grip strength, and joint tenderness. Compared to placebo, guanethidine produced a decrease in pain (p less than 0.025) and an increase in pinch strength (less than 0.025) over the 2-week duration of the study. The therapeutic effect of guanethidine may be mediated by an interruption of the proinflammatory effects of the sympathetic nervous system.
Velocity saturation in few-layer MoS2 transistor (2013)

In this work, we perform an experimental investigation of the saturation velocity in MoS2 transistors. We use a simple analytical formula to reproduce experimental results and to extract the saturation velocity and the critical electric field. Scattering with optical phonons or with remote phonons may represent the main transport-limiting mechanism, leading to saturation velocity comparable to silicon, but much smaller than that obtained in suspended graphene and some III–V semiconductors.
N-3 fatty acids for human nutrition: stability considerations (2002)

Currently there is great interest in dietary n-3 fatty acids to promote health. The food industry aims to produce food products enriched in α-linolenic acid (Ln), eicosapentaenoic acid (EPA) and/or docosahexaenoic acid (DHA) to reduce some of the physiological effects of linoleic acid (L), the major polyunsaturated fatty acid in our diet. However, the goal is hampered by the susceptibility of the n-3 fatty acids to oxidation. As a result the sensory and nutritional quality of such foods deteriorates. Lipid scientists therefore have to find a way to stabilise these fatty acids. Innovative technologies to protect n-3 polyunsaturates using antioxidants, adequate preparation, refining and packaging of the oil are needed. In this paper we review the inherent stability and the stabilisation of these nutritionally valuable polyunsaturated fatty acids.
Sialic acid and Galectins mediate Xenogenic Neutrophil-Endothelial Adhesion (2017)

Abstract Sialic acids (Sias) play multifarious roles in immunity, and likely contribute to inflammation seen in xenograft failure. The ‘net’ cellular sialyation state depends on many things including transient loss of Sia moieties with exposure of subterminal galactosyl structures (mediated by sialyltransferases and sialidases [neuraminidases]), which can function as receptors for extracellular lectins, such as galectins. Here, we report the role of Sias in modulating adhesion of human neutrophils (NΦ’s) to pig endothelial cells. Human (hAECs) and pig (pAECs) aortic endothelial cells were pretreated with Clostridium perfringens neuraminidase (NA, to remove Sias), human tumor necrosis factor (hTNF, 25 ug/ml), or both. CalceinAM-labelled human NΦ’s were treated with rhIL-8, NA, or N-acetyllactosamine (LacNAc, a galectin inhibitor). NΦ adhesion was measured and expressed as percent adhesion. NA treatment of AECs increased NΦ adhesion to pig (36.3% vs 22.4%) more than to human (24.2% vs 20.7%) AECs. NΦ adhesion was similarly increased by TNF activation of AECs in static and flow conditions. hIL-8 dramatically increased NΦ adhesion to pAECs (76.5%, p&amp;lt;.001) and hAECs (45.3%, p&amp;lt;.001), with the highest adhesion observed with NA-treated pAECs and hIL-8-activated NΦ’s. Pre-exposure of the NΦ’s to LacNAc prevented their galectin-mediated adhesion to galactose moieties exposed on the NA-treated pAECs (13.7%, p&amp;lt;.0001). In summary, AEC de-sialylation promotes xenogenic NΦ adhesion, an effect completely inhibited by pre-incubation of Nf’s with LacNAc. These results suggest the inhibition of sialidase activity or galectin binding as promising therapeutic approaches to limit inflammation in xenogeneic organ injury.
Neural maturation of breastfed and formula‐fed infants (2004)

We can conclude that VEP, BAEP and SSEP are more mature in breastfed infants relative to formula-fed infants at 1 y of age, and thus breast milk helps earlier development and maturation of some aspects of the nervous system than milk formulas.
Three-Phase Three-Level Flying Capacitor PV Generation System with an Embedded Ripple Correlation Control MPPT Algorithm (2019)

This paper presents the implementation of a maximum power point tracking (MPPT) algorithm in a multilevel three-phase photovoltaic (PV) system using the ripple correlation control (RCC) method. Basically, RCC adopts the inherent oscillations of PV current and voltage as perturbation, and it has been predominantly used for single-phase configurations, where the oscillations correspond to the 2nd order harmonics. The implementation of an RCC-MPPT algorithm in a three-phase system has not been presented yet in the literature. In this paper, the considered three-phase three-level converter is a three-level flying capacitor (FC) inverter. The proffered RCC method uses the 3rd harmonic components of PV current and voltage for the estimation of the voltage derivative of the power dPpv/dVpv (or current, dIpv/dVpv), compelling the PV array to operate at or very close to the maximum power point. The analysis and calculation of the low-frequency PV current and voltage ripple harmonic components in the three-phase flying capacitor inverter is presented first, with reference to centered carrier-based three-level PWM. The whole grid-connected PV generation scheme has been implemented by MATLAB/Simulink, and detailed numerical simulations verified the effectiveness of the control method in both steady-state and dynamic conditions, emulating different sun irradiance transients.
