Indirect angiogenic cytokines upregulate VEGF and bFGF gene expression in vascular smooth muscle cells, whereas hypoxia upregulates VEGF expression only. (1994)

These results indicate that certain indirect angiogenic cytokines, such as PDGF-BB or TGF-beta 1, may act via induction of bFGF and VEGF gene expression in cells resident near endothelial cells in vivo. Hypoxia constitutes a potent stimulus for VEGF gene expresion but does not regulate bFGF under the same experimental conditions.
Free Latissimus Dorsi Muscle Flap with Skin Graft for Treatment of Traumatic Chronic Bony Wounds (1984)

Based on this review of 35 cases of chronic bony wounds, it would appear that the free-muscle flap method of wound closure and nourishment after thorough dead bone debridement is an attractive and successful alternative to local skin flaps, staged skin flaps, or extend skin-muscle flaps in areas where reliable muscle flaps are not available. It would also seem that the latissimus dorsi muscle flap with skin graft is an ideal donor-muscle transfer with features allowing a favorable and contoured surface in the recipient site and minimal aesthetic and functional deformity in the donor site.
Effect of poly(acrylic acid) molecular mass and end‐group functionality on calcium oxalate crystal morphology and growth (2009)

Abstract A number of series of poly(acrylic acids) (PAA) of differing end‐groups and molecular mass were used to study the inhibition of calcium oxalate crystallization. The effects of the end‐group on crystal speciation and morphology were significant and dramatic, with hexyl‐isobutyrate end groups giving preferential formation of calcium oxalate dihydrate (COD) rather than the more stable calcium oxalate monohydrate (COM), while both more hydrophobic end‐groups and less‐hydrophobic end groups led predominantly to formation of the least thermodynamically stable form of calcium oxalate, calcium oxalate trihydrate. Conversely, molecular mass had little impact on calcium oxalate speciation or crystal morphology. It is probable that the observed effects are related to the rate of desorption of the PAA moiety from the crystal (lite) surfaces and that the results point to a major role for end‐group as well as molecular mass in controlling desorption rate. © 2009 Wiley Periodicals, Inc.

Impact of distribution efficiency on generation and voltage stability (2005)

On-going changes in the electric utility industry are imposing ever stricter constraints upon the operators of transmission networks. The increase in peak load and reduced power margins in the network may under certain circumstances conspire to produce brownouts, or even blackouts, especially when compounded with low probability contingencies. The challenge is also imposed on generation capacity to meet such requirements. An efficient and inexpensive way of coping with those effects is by maintaining sufficient reactive support along the feeders to provide a flat voltage profile, thus allowing deeper levels of voltage reduction when needed. The paper describes how the beneficial effects of voltage reduction allow avoiding adding new capacity to meet peak demand, but also increasing voltage stability margins.
Chromosome‐9 loss detected by fluorescence <i>in situ</i> hybridization in bladder cancer (1995)

A loss of chromosome-9 material is one of the most frequent genomic aberrations known in bladder cancer. In order to better understand the role of chromosome-9 losses in bladder cancer, 125 formalin-fixed and 37 unfixed bladder tumors were examined using fluorescence in situ hybridization (FISH). A repetitive probe for a pericentromeric region on 9q12 (pHUR98) was applied for chromosome-9 copy-number enumeration. Under-representation of chromosome 9 was found in 74 of 162 cases. There was no association between loss of chromosome 9 and increased grade or stage, papillary growth pattern, p53 protein expression, or tumor-cell proliferation (Ki-67). These data show that chromosome-9 loss is an early event in bladder-cancer development, occurring independently of p53 alterations. In order to determine the prevalence of large sub-regional chromosome-9 deletions, dual hybridizations with pHUR98 and cosmid probes for 9q34, 9q22, and 9p21 were performed. Partial deletion was detected in only 1 of 36 cases for 9q34 and in 1 of 24 cases for 9p21. Surprisingly, amplification of the interferon alpha locus on 9p21 was seen in 1 of 24 tumors. The finding of 9p amplification may indicate the site of an oncogene relevant for bladder cancer.
Diagnosis of bacterial contact lens related keratitis with the white-light confocal microscope. (1996)

The confocal microscope permitted the in vivo observation of what we believe to be bacteria in patients diagnosed with contact lens related keratitis.
Sensitized Photolysis on Semiconductors and the Structure of the Latent Image<sup>*</sup> (1978)

The illumination of semiconductor in the intrinsic region of photosensitivity results in a reduction of silver ions adsorbed on the surface of the semiconductor. After this, the latent image can be developed by physical developers. By scanning electron microscopy the nature of the latent image centres is investigated.
Generic Proposal Evaluator: A Lazy Learning Strategy Toward Blind Proposal Quality Assessment (2017)

Existing detection or recognition systems typically select one state-of-the-art proposal algorithm to produce massive object-covered candidate windows, and a quality metric specifically designed for this algorithm is utilized to single out small amounts of proposals. However, in practice, the accuracies of different proposal algorithms significantly change from one image content to another one. To obtain more robust proposal results, a generic proposal evaluator (GPE) is highly desired, which could choose optimal candidate windows across multiple proposal algorithms. In this paper, we propose a lazy learning strategy to train the GPE, which aims to blindly estimate the quality of each proposal without accessing to its manual annotation. Unlike the traditional end-to-end framework that learns a universal model from all training samples, we try to build query-specific training subset for each given proposal, where only its k-nearest-neighborhoods are collected from all labeled candidate windows. Benefits from the capability of updating the regression parameters for different visual contents, the proposed method delivers a higher quality prediction accuracy even with respect to the deep neural network learned by end-to-end method. Experimental results confirm that the proposed algorithm significantly outperforms many state-of-the-art proposal quality metrics.
Sensitivity analysis for wireless dielectric reflectometry with modulated scatterers (2011)

Load-modulated scattering antenna technology has been very efficiently developed these last decades. Low-cost RFID tags for identification and low-invasive Modulated Scattered Technique (MST) probes for EM field measurements constitute two relevant examples. More recently, remote sensing applications of modulated scatterers have been considered. In such applications, the general objective is to remotely retrieve some local property of a material or environment under test via its impact on a modulated scattering probe. This paper is more particularly focused on the case where the sensing mechanism is expected to result from the change of the probe impedance, due to variations of the refractive index in its close vicinity. This problem is usually addressed under empirical and global viewpoints, by combining numerical modeling and optimization. Often, such a blind approach may result in some disappointment. This paper aims to develop a more comprehensive analytical-based approach, thanks to a general reciprocity-based formulation. Inspired from standard reflectometer techniques, the ternary load modulation scheme is shown to remove specific difficulties inherent to wireless reflectometry such as propagation effects or misalignment between the probe and the reader antennas. The test case of center-loaded dipoles is considered for the sake of illustration.
OS support for P2P programming: a case for TPS (2002)

Just as the remote procedure call (RPC) turned out to be a very effective OS abstraction in building client-server applications over LANs, type-based publish-subscribe (TPS) can be viewed as a high-level candidate abstraction for building peer-to-peer (P2P) applications over WANs. This paper relates our preliminary, though positive, experience of implementing and using TPS over JXTA, which can be viewed as the P2P counterpart to sockets. We show that, at least for P2P applications with the Java type model, TPS provides a high-level programming support that ensures type safety and encapsulation, without hampering the decoupled nature of these applications. Furthermore, the loss of flexibility (inherent to the use of any high level abstraction) and the performance overhead, are negligible with respect to the simplicity gained by using TPS.
Towards the generation of rebuttals in a Bayesian Argumentation System (2000)

We describe a mechanism which generates rebuttals to a user's rejoinders in the context of arguments generated from Bayesian networks. This mechanism is implemented in an interactive argumentation system. Given an argument generated by the system and an interpretation of a user's rejoinder, the generation of the rebuttal takes into account the intended effect of the user's rejoinder, determined on a model of the user's beliefs, and its actual effect, determined on a model of the system's beliefs. We consider three main rebuttal strategies: refute the user's rejoinder, strengthen the argument goal, and dismiss the user's line of reasoning.
Impurity Measurement in Specialty Gases Using an Atmospheric Pressure Ionization Mass Spectrometer with a Two-Compartment Ion Source (2001)

Using an atmospheric pressure ionization mass spectrometer (APIMS) with a two-compartment ion source, impurity in specialty gases (CH 4 , SiH 4 , GeH 4 ) is measured due to a stable ionization reaction with a detection limit of approximately 0.1 to 1 parts per billion (ppb). The form in which the impurity exists in these gases has been clarified. In the case of SiH 4 , the main impurity is disiloxane (SiH 3 –O–SiH 3 ). We have also established a method for obtaining the SiH 3 –O–SiH 3 calibration curve standardized for a known concentration of SiH 3 –O–SiH 3 generated from the reaction of SiH 4 with H 2 O. In the case of CH 4 and GeH 4 , the main impurity is moisture (H 2 O) and it is quantified from the plotted H 2 O calibration curve.
Virus-Encoded Cyclin (1994)

Herpesvirus saimiri contains an open reading frame called eclf2 with homology to the cellular type D cyclins. We now show that the eclf2 gene product is a novel virus-encoded cyclin (v-cyclin). The protein encoded by the v-cyclin gene of this oncogenic herpesvirus was found to have an apparent molecular size of 29 kDa in transformed cells. v-Cyclin protein was found to be associated with cdk6, a cellular cyclin-dependent kinase known to interact with cellular type D cyclins. cdk6/v-cyclin complexes strongly phosphorylated Rb fusion protein and histone H1 as substrates in vitro. Mutational analyses showed that highly conserved amino acids in the cyclin box of v-cyclin were important for association with cdk6 and for activation of cdk6 kinase activity. Thus, v-cyclin resembles cellular type D cyclins in primary sequence, in its association with cdk6, by its ability to activate protein kinase activity, and by the presence of functional cyclin box sequences. v-Cyclin exhibited a selective preference for association with cdk6 over other cyclin-dependent kinases and a high level of kinase activation. The properties of v-cyclin suggest a likely role in oncogenic transformation by this T-lymphotropic herpesvirus.
Highly-Sensitive Near-Infrared Spectroscopy System for Remote Monitoring of Concrete Structures (2017)

Salt- or neutralization-induced damage of reinforced concrete structures significantly affects their durability. Because most large-scale infrastructures, such as bridges, urban tunnels, and seawalls, are made of reinforced concrete, developing efficient and accurate methods or devices for early detection of concrete structure damage is important for disaster prevention. Moreover, the cost of a life cycle of a concrete structure can be much lower if surface degradation can be detected and preventive maintenance performed. In this paper, we report the development status of a remote monitoring system that implements remote imaging and diagnosis of the concrete surface degradation. The system consists of a high-sensitivity spectrometer and signal analysis software. The first prototype of the spectrometer was developed using a large-aperture and lossless optical system and a near-infrared camera. Near infrared spectra of samples that simulated salt damage were captured and diagnosed, to analyze the system’s performance. Then, specimens of pure materials constituting concrete were measured, and their absorption spectra were analyzed. Based on the absorption spectra it was concluded that the absorption characteristics of these substances had no influence on the quantification of Friedel’s salt. The prototype machine for field testing has been developed. Using this machine, a series of remote measurement of surface water with up to 10m distance was conducted. And also, measurement of surface degradation on actual concrete structures has been started, to validate the approach. The developed system is expected to rationalize inspection of concrete structures by enabling effective imaging and objective diagnosis of degradation, which will help to clarify which parts or sections of structures need intensive inspection for preventive maintenance.
NeuroMTL iSEG challenge methods (2018)

Abstract We propose a tissue classification method for MRI scans of 6-month old infants, and used it to process the iSeg-2017 challenge data. The method relies on a deep-learning 3D U-Net network, trained with MRI scans of 216 infants, aged 6-24 months, from the ACE-IBIS longitudinal database.
<i>T</i>-matrix analysis of the resonances in sound scattering of an obliquely incident wave from finite elastic spheroids and cylinders (1981)

In this paper, the T-matrix approach is applied to the scattering of plane acoustic waves incident upon finite elastic cylinders and spheroids immersed in water at any angle relative to the bodies axis. Resonances in the range ka 10, where k is the wavenumber of the incidence sound wave and a is the length of the semi-major axis, are isolated. The three angular regions of interest here are 0°, 45°, and 90°. The scattering amplitude and resonances at these angles will be discussed.
Role of Exopolysaccharides of <i>Rhizobium leguminosarum</i> bv. <i>viciae</i> as Host Plant-Specific Molecules Required for Infection Thread Formation During Nodulation of <i>Vicia sativa</i> (1998)

Mutants of Rhizobium leguminosarum bv. viciae bacteria that are affected in the biosynthesis of exopolysaccharides (EPS) are unable to effectively nodulate their host plants. By studying defined mutants, we show that R. legumi-nosarum bv. viciae strains require EPS for formation of infection threads in Vicia sativa (vetch) as well as for efficient induction of tight root hair curling. Results of coinoculation experiments with the EPS-deficient pssD111 mutant of R. leguminosarum bv. viciae in combination with heterologous EPS-producing strains indicated that vetch has certain structural requirements for rhizobial EPS to function in symbiosis. We hypothesize that EPS accelerates root hair curling and infection to such an extent that rhizobial root penetration precedes a plant defense response.
Seafinding By Hatchling Sea Turtles: Role of Brightness, Silhouette and Beach Slope as Orientation Cues (1992)

Abstract Upon emerging from underground nests, sea turtle hatchlings immediately crawl toward the ocean. The primary cues used in orientation are visual but the nature of the visual cues was a matter of speculation. Hatchlings might also respond to secondary cues, such as beach slope. Experiments were carried out in an arena where specific visual and slope cues, simulating those present at nest sites, could be precisely controlled and manipulated. Subjects were green turtle (Chelonia mydas L.) and loggerhead (Caretta caretta L.) hatchlings. Both species oriented toward the more intensely illuminated sections of the arena. They also oriented away from dark silhouettes which simulated an elevated horizon, typical of the view toward land. Turtles responded primarily to stimuli (both silhouettes and photic differences) at or near eye level. When presented simultaneously with a silhouette and a photic gradient located in different directions, hatchlings oriented away from the silhouette and ignored photic stimuli. Under infrared light, both species oriented down slopes. However in the presence of nocturnal levels of visible light loggerheads ignored slope cues and responses of green turtles to slope were weakened. The data suggest that loggerhead and green turtle hatchlings usually find the sea by orienting away from elevated silhouettes. This is a prominent and reliable cue for species which typically nest on continental beaches.
Remote Interactive Browsing of Video Surveillance Content Based on JPEG 2000 (2009)

In video surveillance applications, pre-stored images are likely to be accessed remotely and interactively upon user request. In such a context, the JPEG 2000 still image compression format is attractive because it supports flexible and progressive access to each individual image of the pre-stored content, in terms of spatial location, quality level, as well as resolution. However, when the client wants to play consecutive frames of the video sequence, the purely INTRA nature of JPEG 2000 dramatically penalizes the transmission efficiency. To mitigate this drawback, conditional replenishment mechanisms are envisioned. They convey arbitrary spatio-temporal segments of the initial video sequence directly through sporadic and rate-distortion (RD) optimized refresh of JPEG 2000 packets. Hence, they preserve JPEG 2000 compliance, while saving transmission resources. The replenishment algorithms proposed in this paper are original in two main aspects. First, they exploit the specificities of the JPEG 2000 codestream structure to balance the accuracy (in terms of bit-planes) of the replenishment across image subbands in a (RD)-optimal way. Second, they take into account the still background nature of video surveillance content by maintaining two reference images at the receiver. One reference is the last reconstructed frame, as proposed in the original replenishment framework. The other is a dynamically computed estimate of the scene background, which helps to recover the background after a moving object has left the scene. As an additional contribution, we demonstrate that the embedded nature of the JPEG 2000 codestream easily supports prioritization of semantically relevant regions of interest while browsing video content. An interesting aspect of this JPEG 2000-based prioritization is that it can be regulated <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">a</i> <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">posteriori</i> , after the codestream generation, based on the interest expressed by the user at browsing time. Simulation results demonstrate the efficiency and flexibility of the approach compared to INTER-based solutions.
Impacts of Phosphate Amendments on Lead Biogeochemistry at a Contaminated Site (2002)

Soil amendments can be used to cost-effectively reduce the bioavailability and mobility of toxic metals in contaminated soils. In this study a field demonstration was conducted at a Pb-contaminated site to evaluate the effectiveness of P-induced Pb immobilization. Phosphate was applied at a 4.0 molar ratio of P to Pb with three treatments: T1, 100% of P from H3PO4; T2, 50% P from H3PO4 + 50% P from Ca(H2PO4)2; and T3, 50% P from H3PO4 + 5% phosphate rock. Phosphate amendments effectively transformed soil Pb from the nonresidual (sum of exchangeable, carbonate, Fe/Mn, and organic) to the residual fraction, with residual Pb increase by 19-48% for T1, 22-50% for T2, and 11-55% for T3, respectively. Lead immobilization was attributed to the P-induced formation of chloropyromorphite [Pb10(PO4)6Cl2], which was identified in the surface soil, subsurface soil, and plant rhizosphere soil. Occurrence of chloropyromorphite was evident 220 days after P addition for T1 and T2 treatments and 330 days for T3. Visual MINTEQ model and activity-ratio diagram indicated that lead phosphate minerals controlled Pb2+ activities in the P-treated soils. Phosphate treatments significantly reduced Pb translocation from the roots to the shoots in the St. Augustine grass (Stenotaphrum secundatum), possibly via the formation of chloropyromorphite on the cell walls of roots. This field observation suggested that P amendments are efficient in reducing Pb mobility via in situ formation of insoluble chloropyromorphite minerals at a field setting. Lead immobilization shows a long-term stability. A mixture of H3PO4 and phosphate rock yields the best overall results for in situ Pb immobilization, with less soil pH change and less P leaching. Application of combined H3PO4 with phosphate rock may provide an effective alternative to the current phosphate remediation technologies for contaminated soils.
