Fast Image Mosaic Based on Wavelet Transform for Remote Sensing (2008)

A method of serial fast image mosaic was put forward for the remotely sensed images provided from UAV(unmanned air vehicle),based on wavelet transform and matching of low-frequency images.According to the interior and exterior azimuthal elements of the remotely sensed imaging by UAV,the rectangular spatial transformation and second order linear interpolation are used to correct the images.The method proposed uses the wavelet transform to extract the low-frequency subimages and search the relevant area,thus obtaining the characteristic image as template.Then,the SSDA(sequential similarity detection algorithm) is introduced to perform the image matching computation and after analyzing the result,two images are mosaiked together.Simulation results showed that the algorithm presented greatly improves the operation speed with high precision and that it can be applied to real-time mosaiking of serial images obtained from UAV.

The detector control system of the ATLAS experiment (2008)

The ATLAS experiment is one of the experiments at the Large Hadron Collider, constructed to study elementary particle interactions in collisions of high-energy proton beams. The individual detector components as well as the common experimental infrastructure are supervised by the Detector Control System (DCS). The DCS enables equipment supervision using operator commands, reads, processes and archives the operational parameters of the detector, allows for error recognition and handling, manages the communication with external control systems, and provides a synchronization mechanism with the physics data acquisition system. Given the enormous size and complexity of ATLAS, special emphasis was put on the use of standardized hardware and software components enabling efficient development and long-term maintainability of the DCS over the lifetime of the experiment. Currently, the DCS is being used successfully during the experiment commissioning phase.
Description and Test of a New Multilayer Thin Film Vapor Deposition Apparatus for Organic Semiconductor Materials (2015)

In this work the description, test, and performance of a new vacuum apparatus for thin film vapor deposition (ThinFilmVD) of organic semiconductor materials are presented. The apparatus is able to fabricate single, multilayer/composites, or hybrid thin films using four independent, organic or inorganic, vapor deposition sources (Knudsen cells type), and the vapor mass flow is condensed onto a substrate surface (temperature regulated). The same apparatus could be also used to measure vapor pressures according to the Knudsen effusion methodology. Vapor pressures and thermodynamic properties of sublimation measured by Knudsen effusion of some reference organic materials (benzoic acid, anthracene, triphenylene, benzanthrone, 1,3,5-triphenylbenzene, perylene) were used to evaluate and test the performance of the apparatus. Moreover, nanostructures of thin films and composite materials of relevant charge transport and electroluminescent materials were deposited onto an indium–tin oxide (ITO) surface, and the morphology and thin film thickness were evaluated by scanning electron microscopy (SEM), exploring the effect of different mass flow rates and deposition time. The new physical vapor deposition apparatus based in four Knudsen effusion cells with an accurate mass flow control was designed to assemble well-defined (composition, morphology, thickness) thin films of organic semiconductors based on their volatility. The described apparatus presents a high versatility to the fabrication of single/multilayer thin films, as-grown crystals, and hybrid micro- and nanostructured materials.
RESISTANCE AND ADAPTATION TO FOOD ANTIMICROBIALS, SANITIZERS, AND OTHER PROCESS CONTROLS (2002)

ost antimicrobials used in food manufacture have been in usefor about 50 to 100 years. A few antimicrobials, e.g., sulfites andnitrites, have been in use for an even longer period of time.Similarly, sanitizing agents, used to reduce microorganisms on process-ing equipment, have been in use for nearly 100 years. Concern has beenrecently raised, however, about the potential for target pathogenicmicroorganisms to develop resistance to these compounds.
A General Purpose Positioning System for Construction Robotics (1989)

A General Purpose Positioning System for Construction Robotics Jean-Luc Salagnac Pages 396-403 (1989 Proceedings of the 6th ISARC, San Francisco, USA, ISSN 2413-5844) Abstract: Mobility has been early identified as a key function for future construction robots. It is then essential to develop navigation modules, pilot modules and positioning modules that fit with the constraints of the work site. Concerning the positioning modules (that provides coordinates and orientation of the mobile robot related to a fixed coordinate system), we think that cost alternative and reliable systems must be developed taking into account the peculiarities of construction techniques and methods. This means in particular that the positioning systems to be developed will use either existing measuring devices or different kinds of beacons included in the construction design. This paper presents a patented system belonging to the first class of solutions. The system consists of a rotating laser transmitter installed at a fixed point of the work site. The mobile robot is equipped with suitable sensors providing geometrical information which processed in real time by a computer carried by the mobile robot. The basic principle of this system is described in this paper as well as the experimental developments. Examples of applications of this system are given.

Hyperspectral subpixel target detection using the linear mixing model (2001)

Relative to multispectral sensing, hyperspectral sensing can increase the detectability of pixel and subpixel size targets by exploiting finer detail in the spectral signatures of targets and natural backgrounds. Over the past several years, different algorithms for the detection of full-pixel or subpixel targets with known spectral signature have been developed. The authors take a closer and more in-depth look at the class of subpixel target detection algorithms that explore the linear mixing model (LMM) to characterize the targets and the interfering background. Sensor noise is modeled as a Gaussian random vector with uncorrelated components of equal variance. The paper makes three key contributions. First, it provides a complete and self-contained theoretical derivation of a subpixel target detector using the generalized likelihood ratio test (GLRT) approach and the LMM. Some other widely used algorithms are obtained as byproducts. The performance of the resulting detector, under the postulated model, is discussed in great detail to illustrate the effects of the various operational factors. Second, it introduces a systematic approach to investigate how well the adopted model characterizes the data, and how robust the detection algorithm is to model-data mismatches. Finally, it compares the derived algorithms with regard to two desirable properties: capacity to operate in constant false alarm rate mode and ability to increase the separation between target and background.
<title>Pultrusion of smart FRP composites</title> (1997)

A laboratory scale pultrusion process has been developed to fabricate smart fiber reinforced plastic (FRP) materials. Microstructural analyses of the smart pultruded FRP was carried out using both an optical microscope and a Scanning Electron Microscope. The tensile properties and shear strength, i.e. modulus and strength, of pultruded carbon/vinylester and glass/vinylester rods were determined through mechanical testing. Testing was carried out on baseline pultruded samples, as well as those containing one and two embedded optical fibers. The pultruded carbon reinforced rods with and without optical fiber showed higher shear and tensile strength, as well as greater tensile modulus than did the glass fiber analogue. An embedded optical fiber did not have a significant effect upon the tensile properties of either glass or carbon pultruded FRP rod, but it slightly affected the shear strength of the glass fiber rods. Increased numbers of embedded optical fibers in the FRP rods had a more pronounced influence upon the shear strength. The interfaces between the resin matrix and the buffer coating on the optical fibers were examined and interpreted in terms of the coating's ability to resist high temperatures and its compatibility with resin matrix. Polyimide buffers proved to be superior to acrylate buffers.
Polyalkylcyanoacrylate Nanospheres and Nanocapsules for the Delivery of Antisense Oligonucleotides (2003)

Abstract Active ingredients are being aimed at targets implied in various mechanisms such as nuclear enzymes, receptors, membrane receptors or ionic channels. This non‐specific approach leads to adverse effects. From newly acquired knowledge of the genome, one can now plan to treat diseases by the administration of DNA coding for defective proteins. On the other hand, one can also plan to block expression of harmful proteins such as oncogenic proteins by the use of antisense oligonucleotides. These very short nucleic acids sequences are able to specifically form hybrids with an mRNA and to block the translation of the corresponding protein. However, stability issues and an inability to cross membranes and address suitable cellular compartments still limit the use of oligonucleotides as therapeutic agents. In this review, we focus on nanospheres and nanocapsules made of biodegradable polyisobutylcyanoacrylate polymer for the transport and the targeting of antisense oligonucleotides. Nanospheres are particles on the surface of which the oligonucleotides are adsorbed by ion pair formation using a hydrophobic cation. Nanocapsules are a new type of carrier displaying an aqueous content in which oligonucleotides are dissolved. These two systems both allow protection of oligonucleotides against degradation in the presence of pure serum and lead to in vivo inhibition of tumor growth.
Melatonin Reduces Body Weight Gain in Sprague Dawley Rats with Diet-Induced Obesity (2003)

Melatonin is involved in the regulation of seasonal obesity in various species, including some rodents. This involvement has been demonstrated in nonphotoperiodic rodents like rats, but only in models of enhanced body weight such as genetically obese or middle-aged rats. The aim of this investigation was to determine the effects of melatonin on body weight and metabolic parameters in a model closer to that observed in Western populations, i.e. Sprague Dawley rats fed a high-fat diet. They were treated for 3 wk with melatonin (30 mg/kg) 4 h after lights-on [Zeitgeber time (ZT) 4] or 1 h before lights-out (ZT11). Given at ZT11, melatonin decreased body weight gain and feed efficiency by half. Melatonin had no effect on plasma insulin level, but it decreased plasma glucose (13%), leptin (28%), and triglyceride (28%) levels. Furthermore, in pinealectomized high-fat diet rats, body weight gain and feed efficiency were increased 4 wk after surgery. Adipose tissue weight, insulinemia, and glycemia had a tendency to increase. Treatment with melatonin prevented in part these changes. These data demonstrate that melatonin may act as a regulator of body weight in a model of obesity and may prevent some of the side effects on glucose homeostasis such as decreased insulin sensitivity.
Inhibition of the Activation of Multiple Serine Proteases with a Cathepsin C Inhibitor Requires Sustained Exposure to Prevent Pro-enzyme Processing (2007)

Cathepsin C is a cysteine protease required for the activation of several pro-inflammatory serine proteases and, as such, is of interest as a therapeutic target. In cathepsin C-deficient mice and humans, the N-terminal processing and activation of neutrophil elastase, cathepsin G, and proteinase-3 is abolished and is accompanied by a reduction of protein levels. Pharmacologically, the consequence of cathepsin C inhibition on the activation of these serine proteases has not been described, due to the lack of stable and non-toxic inhibitors and the absence of appropriate experimental cell systems. Using novel reversible peptide nitrile inhibitors of cathepsin C, and cell-based assays with U937 and EcoM-G cells, we determined the effects of pharmacological inhibition of cathepsin C on serine protease activity. We show that indirect and complete inhibition of neutrophil elastase, cathepsin G, and proteinase-3 is achievable in intact cells with selective and non-cytotoxic cathepsin C inhibitors, at concentrations approximately 10-fold higher than those required to inhibit purified cathepsin C. The concentration of inhibitor needed to block processing of these three serine proteases was similar, regardless of the cell system used. Importantly, cathepsin C inhibition must be sustained to maintain serine protease inhibition, because removal of the reversible inhibitors resulted in the activation of pro-enzymes in intact cells. These findings demonstrate that near complete inhibition of multiple serine proteases can be achieved with cathepsin C inhibitors and that cathepsin C inhibition represents a viable but challenging approach for the treatment of neutrophil-based inflammatory diseases.
Progesterone receptors - animal models and cell signaling in breast cancer: The role of oestrogen and progesterone receptors in human mammary development and tumorigenesis (2002)

A relatively small number of cells in the normal human mammary gland express receptors for oestrogen and progesterone (ER and PR), and there is almost complete dissociation between steroid receptor expression and proliferation. Increased expression of the ER alpha (ERalpha) and loss of the inverse relationship between receptor expression and proliferation occur at the very earliest stages of tumorigenesis, implying that dysregulation of ERalpha expression contributes to breast tumour formation. There is evidence also for alterations in the ratio between the two PR isoforms in premalignant breast lesions. Elucidation of the factors mediating the effects of oestradiol and progesterone on development of the normal breast and of the mechanisms by which expression of the ERalpha and the PR isoforms is controlled could identify new targets for breast cancer prevention and improved prediction of breast cancer risk.

The expression of C3b receptors in the differentiation of discoid lupus erythematosus and systemic lupus erythematosus (1990)

We studied the expression of the C3b receptor, CR1, on erythrocytes (E-CR1) of patients who, in spite of having mild systemic symptoms, were diagnosed as having discoid lupus erythematosus and followed accordingly. We found that E-CR1 was markedly reduced in these patients, similar to that seen in patients with systemic disease. In contrast, those patients with completely asymptomatic discoid lupus erythematosus had the same expression of E-CR1 as the normal population.
Toward Electronic Conductance Characterization of DNA Nucleotide Bases (2007)

We calculate electron-transport properties within equilibrium, linear transport theory through the DNA nucleotide bases spanning two gold nanowires. Our quantum mechanical calculations show that single configurations of DNA bases A, C, T, and G have significantly different charge conductance characteristics. This result is consistent with the notion that it is possible to read the nucleotide base sequence on an individual DNA heteropolymer which is moving through a gap between electrically biased nanoelectrodes by measuring the changes in the electron-transport conductance.
High-Pressure Viscosity and Density of Polymer Solutions at the Critical Polymer Concentration in Near-Critical and Supercritical Fluids (2002)

This paper reports on the density and viscosity of solutions of poly(dimethylsiloxane) (PDMS; Mw = 93 700) in supercritical carbon dioxide and of polyethylene (PE; Mw = 121 000) in n-pentane. The measurements have been carried out at critical polymer concentrations, which are 5.5 wt % for a solution of PDMS in CO2 and 5.75 wt % for a solution of PE in n-pentane. For the PDMS + CO2 system, the measurements were conducted at 55, 70, 85, and 100 °C in the pressure range from 30 to 50 MPa. For the PE + n-pentane system, the measurements were conducted at 140 and 150 °C in the pressure range from 10 to 50 MPa using a falling-cylinder-type viscometer. At these temperatures and pressures, the viscosities were observed to be in the range from 0.14 to 0.22 mPa·s for the PDMS + CO2 system and from 2.3 to 4.6 mPa·s for the PE + n-pentane system. The flow activation energies and activation volumes in the PDMS + CO2 system were about 7 kJ/mol and 55 cm3/mol, respectively, compared to about 18 kJ/mol and 70 cm3/mol for the PE + n-pentane system. The close-packed volumes suggested from density correlations were found to be around 0.33 cm3/g for the PDMS system and 0.48 cm3/g for the PE system. Comparison of the viscosity data with the data on the kinetics of pressure-induced phase separation confirms that the slower kinetics in the PE + n-pentane system stems from the higher viscosity in this solution compared to the PDMS + CO2 system, despite the similarity in the molecular weight of the polymer and the critical polymer concentrations.
Results of the LMT81 protocol, a modified LSA<sub>2</sub>L<sub>2</sub> protocol with high dose methotrexate, on 84 children with non‐B‐cell (lymphoblastic) lymphoma (1992)

From May 1981 to June 1989, 84 children with non-B-cell lymphoma (82 lymphoblastic, 1 T-cell immunoblastic, 1 unclassified diffuse lymphoma) were treated in the pediatric department of the Institut Gustave Roussy according to a protocol called LMT81, which was derived from the LSA2L2 protocol of Wollner and modified by the adjunction of 10 courses of high dose methotrexate to improve the CNS prophylaxis. No planned irradiation was performed except in cases of initial tests (2 patients) or CNS (5 patients) involvement and residual mass (2 patients). Sixty patients had mediastinal involvement; for the others, primaries were in the head and neck (7), nodes (2), (sub)cutaneous (4), bone (7), and elsewhere (2). According to Murphy's staging system, there were 2 stage I, 6 stage II, 33 stage III, and 43 stage IV. Among the stage IV patients, 41 had bone marrow involvement, 24 of them with more than 25% blast cells in bone marrow and 19 with blast cells in blood; 7 had CNS involvement. Three patients did not achieve complete remission, 4 died in remission (two measles, one post-transfusion AIDS, one unexplained definitive aplasia) and 13 relapsed at 2 to 29 months (median-13 months). Among the 77 patients without initial CNS involvement, there was only one isolated CNS relapse. With a median follow-up of 57 months (10-106 months), the event-free survival is 75% (SE 2.5) for the 84 patients with a plateau at 29 months, 73% (SE 8) for stage I and II patients, 79% (SE 4) for stage III, and 72% (SE 4) for stage IV patients. Survival was similar in each stage group. Reasons for failure of treatment, however, were different, being toxic deaths in stage II; initial therapy resistance, early relapses, and toxic deaths in stage III; and tumor failures in stage IV. In conclusion, this protocol is efficacious on T and non-T, non-B childhood lymphoma with a low incidence of CNS relapse. A future study will seek to diminish toxicity and long-term sequellae while at least maintaining the same cure rate of patients.
Mutational analysis of the N terminus of the protein of maize transposable element Ac. (1990)

Mutations of transposable element Ac were tested for their capability to excise themselves from their location autonomously, to be excised by an active Ac, or to act in trans in the excision of an Ac delta element. Removal of 101 amino acids from the N terminus of the Ac protein does not decrease excision. A cis-acting site between base pairs 186 and 207 is important for excision by the wild-type protein but is not necessary for excision by the truncated protein. Improvement of the sequence context of the first AUG does not have a significant effect. Mutations in a small open reading frame of Ac encoding a 102-amino acid protein do not visibly alter excision frequency.
On-Line Monitoring Using Electrochemical Noise Measurement in CO-CO2-H2O Systems (1996)

The stress corrosion cracking (SCC) susceptibility of carbon steel extends over a narrow range of potentials in environments that contain a mixture of wet carbon monoxide-carbon dioxide (CO-CO2) gas. Normal fluctuations in plant operation may cause movement in and out of this range of potentials. Stress corrosion cracking in this case is discontinuous, and an opportunity exists to prevent it by process control. Electrochemical noise measurement, because of its capability for operation in thin film condensate conditions, is an attractive technique for monitoring corrosion in wet CO-CO2 systems. Laboratory tests and plant trials were carried out to determine if electrochemical noise measurement could be used to characterize periods of SCC.
Nitric oxide synthases in normal and benign hyperplastic human prostate: Immunohistochemistry and molecular biology (1999)

The expression of nitric oxide synthase (NOS) isoforms has been investigated in normal (three subjects) and benign hyperplastic prostate (ten patients) by immunohistochemistry and reverse transcriptase-polymerase chain reaction (RT-PCR). The inducible NOS (iNOS or NOS-2) is not detected in normal prostate, while it is expressed in the prostate of all benign prostatic hyperplasia (BPH) patients, even in the absence of prostatitis or systemic signs of an inflammatory condition. This suggests that sex hormones may be involved in iNOS induction and that there may be a role for NO in the pathogenesis of BPH. Constitutive NOSs (nNOS and eNOS) are expressed in both normal and hyperplastic prostate and are co-expressed in epithelial cells. eNOS, however, is present mainly in the basal layer cells; nNOS seems abundantly expressed in the more superficial cells of the affected prostate. This indicates that the switching between the two constitutive isoforms may be part of the usual process of cell differentiation from the basal to the secretory layer of the epithelium.
