Investigation of Transmission Properties on 10-kV Medium Voltage Power Lines&mdash;Part I: General Properties (2007)

Based on the empirical data obtained from two typical 10-kV power networks, the transmission properties of the 10-kV power line channel are investigated using the transmission line model. The frequency range is over 40 kHz-1.5 MHz. Our results show: 1) the power attenuation through the channel is about 20-25 dB/km when the channel does not have a branch and 2) the channel is time dispersed. In the frequency domain, the amplitude response is frequency selective while the phase response is linear. In the time domain, the impulse response shows a delay spread. The rms delay spread and the coherence bandwidth are in correlation with the network structure, and the corresponding values are on the order of 10 mus and 10 kHz. 3) The narrow fading of the channel follows Nakagami-m distribution. The channel is varying weakly with respect to time. When the data rate is up to kbps, the channel can be regarded as time invariant.

Cold-cathode source of ribbon gaseous ion beams (2004)

A ribbon ion beam source based on a magnetically confined low-pressure glow discharge has been developed. The electrode system of the ion source consists of four series-installed discharge chambers of the inverted magnetron type with a thin-wire anode. Slots are made in walls between the chambers to equalize the linear distribution of the extracted ion current density. A two-electrode multislit ion optical system 44×3 cm in size forms an ion beam having an energy of up to 20 keV. The operation voltage of the glow discharge with a current of up to 1.6 A in a magnetic field of 2–6 mT at a gas pressure (argon) of 0.015–0.03 Pa is 350–650 V. The ion beam current accounts for 8%–14% of the discharge current. The inhomogeneity of the current density distribution along the ribbon beam axis is 10%–20%.
Adaptive Subframe Allocation for Next Generation Multimedia Delivery Over Hybrid LTE Unicast Broadcast (2016)

The continued global roll-out of long term evolution (LTE) networks is providing mobile users with perpetually increasing ubiquitous access to a rich selection of high quality multimedia. Interactive viewing experiences including 3-D or free-viewpoint video require the synchronous delivery of multiple video streams. This paper presents a novel hybrid unicast broadcast synchronisation (HUBS) framework to synchronously deliver multi-stream content. Previous techniques on hybrid LTE implementations include staggered modulation and coding scheme grouping, adaptive modulation coding or implementing error recover techniques; the work presented here instead focuses on dynamic allocation of resources between unicast and broadcast, improving stream synchronisation as well as overall cell resource usage. Furthermore, the HUBS framework has been developed to work within the limitations imposed by the LTE specification. Performance evaluation of the framework is performed through the simulation of probable future scenarios, where a popular live event is broadcast with stereo 3-D or multi-angle companion views interactively offered to capable users. The proposed framework forms a “HUBS group” that monitors the radio bearer queues to establish a time lead or lag between broadcast and unicast streams. Since unicast and broadcast share the same radio resources, the number of subframes allocated to the broadcast transmission are then dynamically increased or decreased to minimise the average lead/lag time offset between the streams. Dynamic allocation showed improvements for all services across the cell, whilst keeping streams synchronised despite increased user loading.
CrowdDB: Query processing with the VLDB crowd (2011)

Databases often give incorrect answers when data are missing or semantic understanding of the data is required. Processing such queries requires human input for providing the missing information, for performing computationally difficult functions, and for matching, ranking, or aggregating results based on fuzzy criteria. In this demo we present CrowdDB, a hybrid database system that automatically uses crowdsourcing to integrate human input for processing queries that a normal database system cannot answer. CrowdDB uses SQL both as a language to ask complex queries and as a way to model data stored electronically and provided by human input. Furthermore, queries are automatically compiled and optimized. Special operators provide user interfaces in order to integrate and cleanse human input. Currently CrowdDB supports two crowdsourcing platforms: Amazon Mechanical Turk and our own mobile phone platform. During the demo, the mobile platform will allow the VLDB crowd to participate as workers and help answer otherwise impossible queries. 1.
Abstract 544: Development of a Stabilized Bioactive VEGF Chimera for the Management of Preeclampsia (2013)

Preeclampsia is a gestational hypertensive disorder which occurs in 5-10% of all pregnancies in the US. While the underlying cause of the disease is unknown, there is growing recognition that placental ischemia leads to the secretion of pathogenic factors into the maternal blood stream, perhaps most notably the VEGF antagonist sFlt-1. Circulating sFlt-1 sequesters free VEGF and decreases the overall level of VEGF available for cell signaling. Preclinical experiments suggested a palliative effect of VEGF delivery in preeclampsia models, but translation of this therapy is severely hampered by the short half-life of free VEGF and convenient routes of administration. We have recently constructed a VEGF chimera fused to an Elastin Like Polypeptide (ELP) polymer with significantly increased in vivo half-life and stability which appears to retain full VEGF signaling activity. Importantly, we have preliminary evidence that the ELP fusion prevents placental translocation and fetal exposure, preventing harmful fetal effects. ELP-VEGF stimulated normalized HUVEC proliferation at 72hr was dose dependent from 1-100nM, and was equivalent to that of free VEGF (2 ± 0.25 for ELP-VEGF vs 1.94 ± 0.18 at 100nM, p<0.05 versus control for both). Free VEGF (20nM) induced tube formation by HUVECs (8.8 ± 2 vs 14.5 ± 3 tubes/field, p<0.05). Likewise ELP-VEGF significantly increased tube formation compared to control cells (p<0.05), and trended toward augmentation of tube formation versus VEGF alone (18.6 ±4 tubes per frame, p=0.07), though this did not reach significance. Finally, ELP-VEGF (50nM) stimulated HUVEC migration through matrigel (9.9 ± 0.7 vs 3.4 ± 0.3 cells/field, p<0.05) to a similar extent to free VEGF (8.4 ± 0.6 cells/field, p<0.05 vs control). Together, these data suggest that ELP-VEGF retains full VEGF signaling potential, which along with enhanced pharmacokinetic parameters could be a useful therapeutic for the restoration of VEGF signaling in the preeclamptic patient.
Accelerated wound healing in mice by on-site production and delivery of CXCL12 by transformed lactic acid bacteria (2018)

Impaired wound closure is a growing medical problem associated with metabolic diseases and aging. Immune cells play important roles in wound healing by following instructions from the microenvironment. Here, we developed a technology to bioengineer the wound microenvironment and enhance healing abilities of the immune cells. This resulted in strongly accelerated wound healing and was achieved by transforming Lactobacilli with a plasmid encoding CXCL12. CXCL12-delivering bacteria administrated topically to wounds in mice efficiently enhanced wound closure by increasing proliferation of dermal cells and macrophages, and led to increased TGF-β expression in macrophages. Bacteria-produced lactic acid reduced the local pH, which inhibited the peptidase CD26 and consequently enhanced the availability of bioactive CXCL12. Importantly, treatment with CXCL12-delivering Lactobacilli also improved wound closure in mice with hyperglycemia or peripheral ischemia, conditions associated with chronic wounds, and in a human skin wound model. Further, initial safety studies demonstrated that the topically applied transformed bacteria exerted effects restricted to the wound, as neither bacteria nor the chemokine produced could be detected in systemic circulation. Development of drugs accelerating wound healing is limited by the proteolytic nature of wounds. Our technology overcomes this by on-site chemokine production and reduced degradation, which together ensure prolonged chemokine bioavailability that instructed local immune cells and enhanced wound healing.
Lipid utilization by human lymphocytes is correlated with high-density-lipoprotein binding site activity (1992)

The nature and physiological importance of high-density lipoprotein (HDL) binding sites on unstimulated (resting) and mitogen-activated (blast) human peripheral blood lymphocytes were investigated. Specific HDL binding on resting and blast T-lymphocytes was saturable at 50 micrograms of 125I-HDL/ml and of high affinity, with Kd values of 8.1 x 10(-8) M and 6.5 x 10(-8) M, respectively, and Bmax. values of 79 ng and 180 ng/mg of cell protein respectively at 4 degrees C. Binding of HDL double-labelled with fluorescent dioctadecylindocarbocyanine (Dil) and isotope (125I) as well as of single fluorescence- or isotope-labelled HDL was inhibited competitively by HDL apoproteins. Studies of the cholesterol flux between the cells and HDL showed that HDL, low-density lipoprotein (LDL) or BSA at a concentration of 100 micrograms/ml in the tissue culture medium did not result in a significant difference in exogenous [3H]cholesterol efflux from the cell membrane at 37 degrees C. Proliferating T-blasts incorporated more cholesterol from HDL or LDL than did resting lymphocytes. When the cells were pulsed with 125I-HDL and chased in fresh lipid-free medium, up to 80% of the radioactivity released was not precipitable with trichloroacetic acid. This percentage decreased in a competitive manner when unlabelled HDL was present in the chase incubation medium. Finally, cultivation of lymphocytes with conditioned medium from macrophages increased Dil-HDL binding/uptake, while it was decreased by mevinolin-induced inhibition of hydroxymethylglutaryl-coA reductase. In conclusion, human lymphocytes possess a HDL binding site (receptor) responsible for lipid binding/uptake and concomitant internalization and degradation of apoproteins from HDL, but not for reverse cell membrane cholesterol transport. The activity of the binding site is up-regulated during cell proliferation and down-regulated during cell growth suppression.
Small Memory Footprint Neural Network Accelerators (2019)

Deep Neural Network (DNN) accelerators provide high-accuracy data recognition that are commonly used in edge devices. However, resource constrained edge devices usually have small form factors and limited amounts of resources, whereas DNN accelerators require large amounts of computations and memory footprint. In particular, the memory requirements of DNNs become a major bottleneck for realization of accelerators on small footprint devices. To reduce the memory footprint, fused-layer convolutional neural network (CNN) accelerators have been proposed for image recognition networks. Fused-layer CNNs reduce off-chip memory accesses by executing a set of CNN layers on-chip and by replacing the off-chip memory accesses with on-chip memory accesses between the layers. Although fused-layer CNNs reduce the off-chip memory accesses, they still require large amounts of on-chip memories that occupy significant chip area, making impractical their realization on small footprint devices. We address this problem by proposing a design technique that generates fused-CNN accelerators with small memory footprints, demonstrate its potential via a case study.
Vivre à l'ombre de la cathédrale (2003)

L'histoire du quartier de la cathedrale Notre-Dame aux XVIIe et XVIIIe siecles est d'abord marquee par un changement administratif important. C'est en 1622 qu'a l'insistance de Louis XIII le pape Gregoire XV erigea Paris en siege archiepiscopal. Les dioceses de Meaux, Chartres et Orleans, comme Paris detaches de l'archeveche de Sens, devinrent alors suffragant de la nouvelle province ecclesiastique ; Blois s'y ajoutera en 1697. Jean-Francois de Gondi fut nomme premier archeveque de Paris. La famille Gondi, dont de nombreux membres s'illustrerent par une activite religieuse remarquable (on pensera par exemple a Antoinette de Gondi, fondatrice des Benedictines du Calvaire et protectrice de St-Vincent-de-Paul), constituait une veritable dynastie d'eveques : Jean-Francois, lui-meme neveu du cardinal Pierre de Gondi, et frere d'Henri de Gondi, dernier eveque de Paris, laissa sa place en 1654 a son neveu Jean-Francois-Paul, cardinal de Retz, plus accapare par l'intrigue politique que par les devoirs pastoraux incombant a un archeveque. ...
Analysis of seismic anisotropy parameters for sedimentary strata (2016)

ABSTRACT Based on a large quantity of laboratory ultrasonic measurement data of sedimentary rocks and using Monte Carlo simulation and Backus averaging, we have analyzed the layering effects on seismic anisotropy more realistically than in previous studies. The layering effects are studied for different types of rocks under different saturation conditions. If the sedimentary strata consist of only isotropic sedimentary layers and are brine-saturated, the δ value for the effective transversely isotropic (TI) medium is usually negative. The δ value will increase noticeably and can be mostly positive if the sedimentary strata are gas bearing. Based on simulation results, c13 can be determined by other TI elastic constants for a layered medium consisting of isotropic layers. Therefore, δ can be predicted from the other Thomsen parameters with confidence. The theoretical expression of δ for an effective TI medium consisting of isotropic sedimentary rocks can be simplified with excellent accuracy into a neat form. The anisotropic properties of the interbedding system of shales and isotropic sedimentary rocks are primarily influenced by the intrinsic anisotropy of shales. There are moderate to strong correlations among the Thomson anisotropy parameters.

Regulatory interactions between muscle and the immune system during muscle regeneration (2010)

Recent discoveries reveal complex interactions between skeletal muscle and the immune system that regulate muscle regeneration. In this review, we evaluate evidence that indicates that the response of myeloid cells to muscle injury promotes muscle regeneration and growth. Acute perturbations of muscle activate a sequence of interactions between muscle and inflammatory cells. The initial inflammatory response is a characteristic Th1 inflammatory response, first dominated by neutrophils and subsequently by CD68(+) M1 macrophages. M1 macrophages can propagate the Th1 response by releasing proinflammatory cytokines and cause further tissue damage through the release of nitric oxide. Myeloid cells in the early Th1 response stimulate the proliferative phase of myogenesis through mechanisms mediated by TNF-alpha and IL-6; experimental prolongation of their presence is associated with delayed transition to the early differentiation stage of myogenesis. Subsequent invasion by CD163(+)/CD206(+) M2 macrophages attenuates M1 populations through the release of anti-inflammatory cytokines, including IL-10. M2 macrophages play a major role in promoting growth and regeneration; their absence greatly slows muscle growth following injury or modified use and inhibits muscle differentiation and regeneration. Chronic muscle injury leads to profiles of macrophage invasion and function that differ from acute injuries. For example, mdx muscular dystrophy yields invasion of muscle by M1 macrophages, but their early invasion is accompanied by a subpopulation of M2a macrophages. M2a macrophages are IL-4 receptor(+)/CD206(+) cells that reduce cytotoxicity of M1 macrophages. Subsequent invasion of dystrophic muscle by M2c macrophages is associated with progression of the regenerative phase in pathophysiology. Together, these findings show that transitions in macrophage phenotype are an essential component of muscle regeneration in vivo following acute or chronic muscle damage.
Self-Limiting Robust Surface-Grafted Organic Nanofilms (2010)

Robust surface-bound insulating polymer films with controlled thickness in <5 nm range are important for technological advances in diverse disciplines such as electrochemical sensors, molecular electronics, separations and anti-corrosive coatings. Creating these films by simple methods from readily available materials has been a significant challenge. Here we report a newly synthesized molecule combining a styrene and thiol moieties, joined via a short linker, that binds to the gold surface, polymerizes and crosslinks polymer chains to form robust films with uniform and controlled thickness and complete surface coverage. Additional layers can be deposited. These films that bridge two- and three-dimensional materials show excellent stability and insulating properties.
Model building by comparison at CASP3: Using expert knowledge and computer automation (1999)

Ten models were constructed for the comparative modeling section of the Critical Assessment of Techniques for Protein Structure Prediction-3 (CASP3). Sequence identity between each target and the best possible parent(s) ranged between 12% and 64%. The modeling protocol is a mixture of automated computer algorithms with human intervention at certain critical stages. In particular, intervention is required to check sequence alignments and the selection of parameters for various computer programs. Seven of the targets were constructed from single-parent templates, and three were constructed from multiple parents. The reasons for such a high ratio of modeling from single parents only are discussed. Models constructed from multiple parents were found to be more accurate than models constructed from single parents only. A novel loop-modeling algorithm is presented that consists of fragment database searches, several fragment libraries, and mean-field calculations on representative fragment candidates.
New Biased-Reptation Model For Charged Polymers (1985)

We study entangled charged polymers in an electric field with a new biased-reptation model. Two microscopic time scales are relevant: the usual tube disengagement time ${T}_{D}$, and a new chain stretching time constant ${\ensuremath{\tau}}_{\mathrm{str}}$. When ${\ensuremath{\tau}}_{\mathrm{str}}<{T}_{D}$, i.e., for long chains and/or high electric fields, the chains are stretched in the field direction. As an example, we discuss DNA gel electrophoresis in terms of these results. Experimental and theoretical investigations are suggested.
Implementation of vibro-acoustography on a clinical ultrasound system (2011)

Vibro-acoustography is an ultrasound-based imaging modality that uses two ultrasound beams of slightly different frequencies to produce images based on the acoustic response caused by harmonic ultrasound radiation force excitation at the difference frequency between the two ultrasound frequencies. Vibro-acoustography has demonstrated feasibility and usefulness in imaging of breast and prostate tissue. However, previous studies have been performed either in controlled water tank settings or a prototype breast scanner equipped with a water tank. To make vibro-acoustography more accessible and relevant to clinical use, we report here on the implementation of vibro-acoustography on a General Electric Vivid 7 ultrasound scanner. In this paper, we will describe software and hardware modifications that were performed to make vibro- acoustography functional on this system. We will discuss aperture definition for the two ultrasound beams and beamforming using a linear-array transducer. Experimental results from beam measurements and phantom imaging studies will be shown. The implementation of vibro-acoustography provides a step toward clinical translation of this imaging modality for applications in various organs including breast, prostate, thyroid, kidney, and liver.
Substitution of Ammonium and Potassium for Added Calcium in Reduction of Ammonia Loss from Surface‐applied Urea (1982)

Abstract Ammonia (NH 3 ) volatilization loss from surface application of urea must be reduced if urea is to gain further acceptance for use in pastures and on other non‐ or low‐tillage systems which do not permit soil incorporation. The method used to reduce NH 3 loss should not increase costs of the N fertilizer significantly. Preferably, the material used should itself be a fertilizer nutrient. The nitrate salts of the monovalent cations NH + 4 , K + , and Na + were tested as substitutes for chloride or nitrate salts of Ca 2+ to depress NH 3 losses when mixed with surface‐applied urea. Ammonia losses were measured from soils with different cation exchange capacities (CEC) in the laboratory, with residual N quantified by growing sudangrass on the variously treated soils under greenhouse conditions. Laboratory and/or greenhouse data indicate that NH 3 loss from surface‐applied urea was most effectively reduced by Ca salts. Substitution of K, Na, and NH 4 salts for Ca salts was increasingly effective as soil CEC increased. Monovalent salts were effective in reducing NH 3 losses if the soil had exchangeable Ca 2+ + Mg 2+ . In sand, however, monovalent salts did not reduce NH 3 losses. The order of effectiveness on nonsandy soils was Na + = K + > NH + 4 in reducing NH 3 loss. Potassium as KNO 3 or KCl can be used effectively to partially replace (Ca + Mg) nitrate or chloride salts with urea to reduce NH 3 losses. Ammonium nitrate was ineffective in reducing NH 3 losses except where high N application rates were used or where little or no soil CEC existed. The efficacy of NH 4 NO 3 seemed to be due to its acidic nature more than displacement of exchangeable Ca 2+ + Mg 2+ .
Improved Equation of the Continuous Particle Size Distribution for Dense Packing (1990)

The Furnas model describes the discrete particle size distribution for densest packing. Using a model that considers a continuous particle size distribution for the densest packing to be a mixture of infinite Furnas discrete particle size groups, an equation for the cumulative particle size distribution providing the densest packing was derived. Monosize particles with different shapes have a different packing pore fraction. One parameter in the equation is the pore fraction of packed monosize particles; the particle size distribution for achieving densest packing is a function of this pore fraction. A reduced form of this equation is also presented as a working equation. The equation derived here is compared to the modified Andreasen equation for dense packing. An equation and the correlated graph for calculating theoretically the geometric mean particle size and an equation for calculating the specific surface area of the particle size distribution of the improved equation are also derived.
