Non-local means-based nonuniformity correction for infrared focal-plane array detectors (2014)

The infrared imaging systems are normally based on the infrared focal-plane array (IRFPA) which can be considered as an array of independent detectors aligned at the focal plane of the imaging system. Unfortunately, every detector on the IRFPA may have a different response to the same input infrared signal which is known as the nonuniformity problem. Then we can observe the fixed pattern noise (FPN) from the resulting images. Standard nonuniformity correction (NUC) methods need to be recalibrated after a short period of time due the temporal drift of the FPN. Scene-based nonuniformity correction (NUC) techniques eliminate the need for calibration by correction coefficients based on the scene being viewed. However, in the scene-based NUC method the problem of ghosting artifacts widely seriously decreases the image quality, which can degrade the performance of many applications such as target detection and track. This paper proposed an improved scene-based method based on the retina-like neural network approach. The method incorporates the use of non-local means (NLM) method into the estimation of the gain and the offset of each detector. This method can not only estimates the accurate correction coefficient but also restrict the ghosting artifacts efficiently. The proposed method relies on the use of NLM method which is a very successful image denoising method. And then the NLM used here can preserve the image edges efficiently and obtain a reliable spatial estimation. We tested the proposed NUC method by applying it to an IR sequence of frames. The performance of the proposed method was compared the other well-established adaptive NUC techniques.

CEP-1347 inhibits caerulein-induced rat pancreatic JNK activation and ameliorates caerulein pancreatitis (2000)

Pancreatic caerulein-induced activation of c-Jun NH(2)-terminal kinase (JNK) has been reported, and JNK has been proposed as a mediator during induction of hyperstimulated pancreatitis. CEP-1347 has recently been described as a specific JNK inhibitor. We tested whether CEP-1347 inhibits caerulein-induced pancreatic JNK activation in isolated acini and in vivo. CEP-1347 dose dependently inhibited acinar caerulein-induced JNK activation with nearly complete inhibition at 2 microM but had no effect on digestive enzyme release. For in vivo studies, rats were pretreated with CEP-1347 before caerulein hyperstimulation. For assessment of JNK activation and histological alterations, animals were killed 30 min or 2 and 4 h after caerulein hyperstimulation, respectively. Pancreatic wet weight, serum enzyme levels, and pancreatic activity of p38 and extracellular signal-regulated kinase (ERK) were also determined. Caerulein hyperstimulation strongly activated JNK, p38, and ERK. CEP-1347 pretreatment dose dependently reduced caerulein-induced pancreatic JNK activation without p38 or ERK inhibition. JNK inhibition also reduced pancreatic edema formation and reduced histological severity of pancreatitis. Thus we show that CEP-1347 inhibits JNK activation in vivo and ameliorates caerulein-induced pancreatitis.

Segregation Growth of Graphene on Cu–Ni Alloy for Precise Layer Control (2011)

A facile way to segregate wafer-size graphene with controllable layer number using Cu–Ni binary alloy under vacuum annealing condition is presented here. Increasing atomic percentage of Ni in Cu–Ni alloy was found to segregate thicker uniform graphene. To date, over 95% monolayer and 91% bilayer graphene films have been prepared by only changing atomic percentage of Ni in Cu–Ni alloy, respectively. The synergetic combination of the distinct carbon solubilities of Cu and Ni and the well-known segregation phenomenon is believed to be responsible for the formation of high-quality uniform few layer graphene. Together with the easy detachment from growth substrates, we believe this facile segregation technique will offer a great driving force for graphene research.

OS-level hang detection in complex software systems (2011)

Many critical services are nowadays provided by large and complex software systems. However, the increasing complexity introduces several sources of non-determinism, which may lead to hang failures : the system appears to be running, but part of its services is perceived as unresponsive. Online monitoring is the only way to detect and to promptly react to such failures. However, when dealing with off-the-shelf-based systems, online detection can be tricky since instrumentation and log data collection may not be feasible in practice. In this paper, a detection framework to cope with software hangs is proposed. The framework enables the non-intrusive monitoring of complex systems, based on multiple sources of data gathered at the operating system (OS) level. Collected data are then combined to reveal hang failures. The framework is evaluated through a fault injection campaign on two complex systems from the air traffic management (ATM) domain. Results show that the combination of several monitors at the OS level is effective to detect hang failures in terms of coverage and false positives and with a negligible impact on performance.
Self-healing Effect of Boron Nitride Precipitation on Creep Cavitation in Austenitic Stainless Steel (2006)

In this study, the precipitation of boron nitride (BN) on creep cavity surfaces during creep and its beneficial effect on the creep rupture properties are reported for a type 304 austenitic stainless steel. In the conventional 304 stainless steel, the trace of soluble S segregates strongly on the creep cavity surfaces and promotes its growth during creep. In the modified 304 stainless steel added with B, Ce, and Ti, the trace of soluble S is removed effectively by the formation of Ce and Ti sulfides, and the segregation of S on the creep cavity surface is replaced by the precipitation of the BN compound. As BN is very stable at high temperatures, its precipitation on the cavity surface is expected to suppress the creep cavity growth rate. It is suggested that the precipitation of BN on the creep cavity surface provides austenitic stainless steel with the function of self-healing for creep cavitation with an associated increase in the creep rupture strength and ductility.

La madera en los pertrechos navales. Provisión de motones, remos y bombas al arsenal de La Carraca (2004)

El Tratado de Utrecht obliga a Espana a emprender una politica decididamente atlantista que requiere una verdadera reconversion de la armada. Unos cambios tan profundos requerian acometer la renovacion naval desde una proyeccion integral, recayendo esta iniciativa sobre los arsenales. Estas bases navales se erigiran en complejos donde se abordarian cuestiones como la renovacion tipologica de los barcos, los constructores, la fabrica de embarcaciones, el mantenimiento de las mismas y la gestion de los pertrechos.

These deep changes required to face the naval renovation from a integral proyection, going this initiative to the navy yards. This naval posts will set themselves up in complexes where questions such as shipping tipological renovations, building, maintenance and sources management will be tackled.
Regioselective Functionalization of Starch:  Synthesis and <sup>1</sup>H NMR Characterization of 6-<i>O</i>-Silyl Ethers (2001)

A high regioselective 6-O silylation of starch by using thexyldimethylchlorosilane (TDSCl, chlorodimethyl-(2,3-dimethylbut-2-yl)silane) as bulky silylating agent in the reaction system N-methylpyrrolidone (NMP)/ammonia was carried out and investigated. The control of the degree of substitution (DSSi), the control of the regioselectivity, and the control of the reaction pathway are described in detail. After peracetylation of the silyl ethers of starch, the distribution of the silyl and acetyl substituents was characterized not only in the anhydroglucose repeating units (AGU) but also in the nonreducing end groups (NEG) by means of multidimensional 1H NMR techniques. In both cases, the silyl substituents were detected exclusively in the 6-O position, and the acetyl groups in the 2-O and 3-O positions of the AGU and in the 2-O, 3-O, and 4-O positions of the NEG, respectively. The described 6-O-thexyldimethylsilyl (TDS) units are potentially protecting groups of the primary OH position of starches.
High–power terahertz synchrotron sources (2003)

Electromagnetic waves, or light, are produced by accelerating electrons according to the formula assigned the name of Sir Joseph Larmor, who was secretary of The Royal Society from 1901 to 1912. For relativistic electrons the emission is enhanced by the fourth power of the increase in mass. Thus for 10 MeV electrons, for which the mass increases by a factor of 21, the enhancement is a factor of 200000. We have generated high-power broadband THz light using relativistic electrons and demonstrated that ca. 100 W can readily be produced in a band from 0.1 to 3 THz with possible extensions to 6 THz. The experiments use a new generation of light source in which bunches of electrons circulate once, but in which their energy is recovered. In such a machine the electron bunches can be very much shorter than those, say, in storage rings or synchrotrons.
Detection of Low-Mr Glycoproteins in Surface Washes of Some Fungal Cultures by Gel-filtration HPLC and by Monoclonal Antibodies (1989)

Surface washings were prepared from cultures of fungi grown on agar slants and the wash components were fractionated by gel-filtration HPLC. A range of low-Mr glycoproteins (less than 10,000) were detected in all the washes, and in some species several high-Mr glycoprotein components (greater than 150,000) were also present. The HPLC analyses indicated species-specific differences in the profiles. Regions of specific antigenicity within profiles were detected by monoclonal antibodies.
Studies on Simultaneously Detecting Multiple Antibodies in The Serum Using Microarray (2002)

An optimized method has been established to simultaneously detect multiple antibodies of HIV, TP and HCV in the serum by the way of microarray. Chimeric antigens of HIV, TP and HCV are covalently bound to the surface of glass slide; serum samples are diluted and added to the well of microarray, unbound antibodies are washed away after incubation, and Cy3 labeled second antibody is added to the well followed by incubation and washing. The microarray is scanned by laser confocal scanner, and the resulting images are treated by the software of Imagene (produced by Bio discover Co.). The data obtained is then treated by the software produced by own; the evaluated result of each sample is finally gained automatically by the Cutoff value of each antigen. 400 normal serum sample are detected and Cutoff value of each antigen are determined. National panels of HIV, TP and HCV had also been detected by this system and the results were compared with those detected by ELISA method. The coordinate ratios of positive and negative samples of HIV panel are both 100% (20/20); these kinds of the coordinate ratios of positive and negative samples of HCV are both 95%(38/40) and the coordinate ratios of positive and negative samples of TP are 100%(10/10) and 100%(20/20) respectively. This result is highly in accord with that of ELISA method.
Effects of Polyhydric Alcohols on the Mechanical Properties of Soy Protein Plastics (1996)

Abstract Polyhydric alcohols, i.e., ethylene glycol, glycerol, propylene glycol, 1,3-propanediol (trimethylene glycol), and polyethylene glycol (200 and 400), were investigated for their plasticizing effects on soy protein plastics. Tensile strength and percentage elongation at break of compression-molded soy protein specimens containing each of the polyhydric alcohols were measured, and Young's modulus was calculated. Ethylene glycol and glycerol demonstrated the greatest effects on the tensile properties. Differential scanning calorimetric (DSC) thermograms of soy protein with glycerol showed a major exothermic transition. Dynamic mechanical spectra showed that dry plastic specimens had a shear-storage modulus (G' = 1.76 GPa) about 50% larger than those of the high performance synthetic polymers tested. The shear-storage modulus was little dependent on temperature change up to ca. 130°C. After the specimens were moisturized at 50% relative humidity, the G' was reduced to 0.22 GPa. The shear-storage modulus of specimens containing 30% glycerol decreased when the temperature increased above −60°C. Rheological properties of soy protein with and without glycerol were evaluated by using a torque rheometer.

Spatiotemporal progression of cell death in the zone of ischemia surrounding burns (2011)

Burns are dynamic injuries, characterized by progressive death of surrounding tissue over time. Although central to an understanding of burn injury progression, the spatiotemporal degrees and rates of cellular necrosis and apoptosis in the zone of ischemia surrounding burns are not well characterized. Using a validated porcine hot comb model, we probed periburn tissue at 1, 4, and 24 hours after injury for high-mobility group box 1 as a marker of necrosis and activated cleaved caspase-3 as a marker of apoptosis, followed by spatiotemporal morphometric analysis. We found that necrosis was the most prominent mechanism of cell death in burn injury progression, with significant progression between 1 and 4 hours postburn. Apoptosis appeared not to play a role in early burn injury progression but was observed in cells at the interface of necrotic and viable tissue at 24 hours postburn. Our findings imply that intervention within the first 4 hours following injury is likely necessary to limit burn injury progression. Additionally, based on high-mobility group box 1 staining patterns, we define distinct early, intermediate, and late pathological signs of cell necrosis that may facilitate delineation of causal mechanistic relationships of burn injury progression in vivo.
Highly Polarized Luminescence from Optical Quality Films of a Semiconducting Polymer Aligned within Oriented Mesoporous Silica (2004)

In this Communication, we show that nanometer scale control of semiconducting polymer chain conformation is possible using host/guest chemistry in highly ordered and macroscopically oriented thin films of mesoporous silica. This control leads to a thin film composite material that is optically transparent, densely filled with polymer, and has highly polarized optical properties. Calculations of absorption and emission anisotropies further indicate full incorporation of the polymer into the nanoscale pore spaces. Such materials could serve as a useful tool for further investigations of polymer photophysics, as well as for device applications.
Performance analysis of an in-band COFDM/FM digital audio broadcasting system (2002)

Over the past few years, digital technologies have been growing in such a way that a new generation of fully digital audio broadcasting systems can now become cost effective. For this purpose coded orthogonal frequency division multiplexing (COFDM), a new transmission technique designed in Europe, seems promising. To avoid the allocation of a new bandwidth in the United-States, some groups are proposing the use of power multiplexing to transmit two different signals over the same bandwidth. The objective of this work is to analyze the feasibility of this system taking into account the CD-like quality level of digital audio broadcasting systems (DAB).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Tracing Genres through Organizations: A Sociocultural Approach to Information Design (2003)

In Tracing Genres through Organizations, Clay Spinuzzi examines the everyday improvisations by workers who deal with designed information and shows how understanding this impromptu creation can improve information design. He argues that the traditional user-centered approach to design does not take into consideration the unofficial genres that spring up as workers write notes, jot down ideas, and read aloud from an officially designed text. These often ephemeral innovations in information design are vital components in a genre ecology (the complex of artifacts mediating a given activity). When these innovations are recognized for what they are, they can be traced and their evolution as solutions to recurrent design problems can be studied. Spinuzzi proposes a sociocultural method for studying these improvised innovations that draws on genre theory (which provides the unit of analysis, the genre) and activity theory (which provides a theory of mediation and a way to study the different levels of activity in an organization).After defining terms and describing the method of genre tracing, the book shows the methodology at work in four interrelated studies of traffic workers in Iowa and their use of a database of traffic accidents. These workers developed an ingenious array of ad hoc innovations to make the database better serve their needs. Spinuzzi argues that these inspired improvisations by workers can tell us a great deal about how designed information fails or succeeds in meeting workers' needs. He concludes by considering how the insights reached in studying genre innovation can guide information design itself.

Acemannan, an Extracted Product from <i>Aloe Vera</i> , Stimulates Dental Pulp Cell Proliferation, Differentiation, Mineralization, and Dentin Formation (2010)

This study investigated the effect of acemannan (Aloe vera gel polysaccharide) on dentin formation. Primary human dental pulp cells were treated with acemannan. New DNA synthesis, bone morphogenetic protein-2, alkaline phosphatase activity, dentin sialoprotein expression, and mineralization were determined by [(3)H]-thymidine incorporation, enzyme-linked immunosorbent assay, biochemical assay, western blotting, and Alizarin Red staining, respectively. Then the upper first molars of 24 male Sprague Dawley rats were intentionally exposed and capped with either acemannan or calcium hydroxide. At day 28, the teeth were histopathologically examined and evaluated for the degree of inflammation, dentin bridge formation, and pulp tissue organization. The results revealed that acemannan significantly increased pulp cell proliferation, bone morphogenetic protein-2, alkaline phosphatase activity, dentin sialoprotein expression, and mineralization, compared with the untreated group. The acemannan-treated group also exhibited a complete homogeneous calcified dentin bridge and good pulp tissue organization, whereas neither was detected in the calcium hydroxide-treated and sham groups. In the acemannan-treated group, either mild or no inflammation was found, whereas the other groups had various degrees of inflammation. The data suggest that acemannan promotes dentin formation by stimulating primary human dental pulp cell proliferation, differentiation, extracellular matrix formation, and mineralization. Acemannan also has pulpal biocompatibility and promotes soft tissue organization.

Highly stabilised evaporation sources in a water-cooled carousel housing (1982)

The construction of a water-cooled housing for highly stabilised evaporation sources used in UHV for preparation of ultrathin metal films is described. Five different sources, which can be rotated one-by-one into position, give a perpendicular beam flux relative to the substrate surface. The design and performance of two highly stabilised metal evaporation sources with crucibles of graphite and boron nitride respectively are described. The temperature stability and decomposition of the graphite-type source are presented and discussed in detail. Furthermore the construction and experimental details are given for a high-purity carbon evaporation source exploiting the electron bombardment technique.
