Coercivity and nanostructure of melt-spun Ti-Fe-Co-B-based alloys (2016)

Nanocrystalline Ti-Fe-Co-B-based alloys, prepared by melt spinning and subsequent annealing, have been characterized structurally and magnetically. X-ray diffraction and thermomagnetic measurements show that the ribbons consist of tetragonal Ti3(Fe,Co)5B2, FeCo-rich bcc, and NiAl-rich L21 phases; Ti3(Fe,Co)5B2, is a new substitutional alloy series whose end members Ti3Co5B2 and Ti3Fe5B2 have never been investigated magnetically and may not even exist, respectively. Two compositions are considered, namely Ti11+xFe37.5-0.5xCo37.5−0.5xB14 (x = 0, 4) and alnico-like Ti11Fe26Co26Ni10Al11Cu2B14, the latter also containing an L21-type alloy. The volume fraction of the Ti3(Fe,Co)5B2 phase increases with x, which leads to a coercivity increase from 221 Oe for x = 0 to 452 Oe for x = 4. Since the grains are nearly equiaxed, there is little or no shape anisotropy, and the coercivity is largely due to the magnetocrystalline anisotropy of the tetragonal Ti3(Fe,Co)5B2 phase. The alloy containing Ni, Al, and Cu exhibits a magnetization of 10.6 kG and a remanence ratio of 0.59. Our results indicate that magnetocrystalline anisotropy can be introduced in alnico-like magnets, adding to shape anisotropy that may be induced by field annealing.
Advances in the Synthesis of Fluorinated Scaffolds by Transition Metal-Catalyzed C–H Bond Activation (2020)

Thanks to the unique features of the fluorine atom and the fluorinated groups, fluorine-containing molecules are essential. Therefore, the search for new fluorinated groups as well as straightforward and original methodologies for their installation is of prime importance. Especially, the combination of organofluorine chemistry with transition metal-catalyzed C-H bond functionalization reactions offered straightforward tools to access original fluorinated scaffolds. In this context, over the last years, our group focused on the development of original methodologies to synthesize fluorine-containing molecules with a special attention to emergent fluorinated groups. The present account highlights our recent contributions to the synthesis of highly value-added fluorine-containing compounds by transition metal-catalyzed C-H bond activation.
Origin of the low frequency radiation emitted by radiative polaritons excited by infrared radiation in planar La2O3films (2012)

Upon excitation in thin oxide films by infrared radiation, radiative polaritons are formed with complex angular frequency ω, according to the theory of Kliewer and Fuchs (1966 Phys. Rev. 150 573). We show that radiative polaritons leak radiation with frequency ω(i) to the space surrounding the oxide film. The frequency ω(i) is the imaginary part of ω. The effects of the presence of the radiation leaked out at frequency ω(i) are observed experimentally and numerically in the infrared spectra of La(2)O(3) films on silicon upon excitation by infrared radiation of the 0TH type radiative polariton. The frequency ω(i) is found in the microwave to far infrared region, and depends on the oxide film chemistry and thickness. The presented results might aid in the interpretation of fine structures in infrared and, possibly, optical spectra, and suggest the study of other similar potential sources of electromagnetic radiation in different physical scenarios.
Mineralogy and Mobility Pattern of Trace Metals in Brine Irrigated Dry Disposed Weathered Coal Fly Ash (2015)

This study determines mineralogical association of trace elements in the ash core samples and provides insight into various factors that promote their mobility and eventual release into surface and groundwater systems. Fly ash from a power station ash dump in Mpumalanga Province (South Africa) was characterized using X-ray diffraction and X-ray fluorescence. A five-step sequential extraction procedure was used to determined mineralogical association of elements as a function of depth in the ash dump. The dry disposed ash cores are sialic in chemical composition. The mineral peak height as revealed by X-ray diffraction analysis showed variations due to heterogeneity in the ash dump and in homogenous continuous brine irrigation. The sequential extraction results showed that some trace elements are moving in a leaching pathway through the fly ash in the water soluble fraction. Toxic analytes are present in water soluble, exchangeable, and carbonate fractions. Observed Pb concentration maxima in the carbonate fraction of ash cores suggests mobility due to reduction in the pore water pH. A relatively high concentration of As and Se in the exchangeable fraction indicates their possible release when fly ash comes in contact with slightly acidic rain water. This is of major environmental concern for possible contamination of surface and groundwater systems. The relative enrichment of As and Se in the residual fraction suggests that the dust from 8-year-old brine irrigated ash dump would be toxic to human health. This investigative study demonstrates that reduction in pore water pH, inhomogeneity in the ash dump, continuous brine irrigation, leachate from topsoil, moisture content level, ingressed CO2 from atmosphere, and percolating rain water are factors that promote trace metal mobility and leaching in the brine irrigated dry disposed ash dump.
Transplantation of Cryopreserved Adult Human Schwann Cells Enhances Axonal Conduction in Demyelinated Spinal Cord (2001)

Schwann cells derived from human sural nerve may provide a valuable source of tissue for a cell-based therapy in multiple sclerosis. However, it is essential to show that transplanted human Schwann cells can remyelinate axons in adult CNS and improve axonal conduction. Sections of sural nerve were removed from amputated legs of patients with vascular disease or diabetes, and Schwann cells were isolated and cryopreserved. Suspensions of reconstituted cells were transplanted into the X-irradiation/ethidium bromide lesioned dorsal columns of immunosuppressed Wistar rat. After 3-5 weeks of extensive remyelination, a typical Schwann cell pattern was observed in the lesion zone. Many cells in the lesion were immunopositive for an anti-human nuclei monoclonal antibody. The dorsal columns were removed and maintained in an in vitro recording chamber; the conduction properties were studied using field potential and intra-axonal recording techniques. The transplanted dorsal columns displayed improved conduction velocity and frequency-response properties, and action potentials conducted over a greater distance into the lesion, suggesting that conduction block was overcome. These data support the conclusion that transplantation of human Schwann cells results in functional remyelination of a dorsal column lesion.
Semisynthetic aminoglycoside antibacterials. Part 10. Synthesis of novel 1-N-aminoalkoxycarbonyl and 1-N-aminoalkylcarboxamido derivatives of sisomicin, gentamicin B, gentamicin C1a, and kanamycin A (1981)

Suitably protected derivatives of sisomicin, 5-epi-sisomicin, gentamicin B, gentamicin C1a, and kanamycin A have been converted into a series of 1-N-alkoxycarbonyl, 1-N-alkoxycarbonyl, 1-N-carboxamido, 1-N-alkylcarboxamido, and 1-N-aminoalkylcarboxamido derivatives. Representative thio-analogues have also been prepared. 13C N.m.r. studies have revealed that these novel semisynthetic aminoglycosides have different solution conformations about the C-6–O glycosidic bond relative to the parent aminoglycosides from which they are derived.
Detection of Five Common CFTR Mutations by Rapid-Cycle Real-Time Amplification Refractory Mutation System PCR (2004)

Cystic fibrosis is the most common autosomal recessive disease in Caucasian populations and has a carrier frequency of 1 in 25 (1). The gene involved codes for the cystic fibrosis transmembrane conductance regulator (CFTR), a membrane-associated protein involved in ion transport across the plasma membrane of epithelial cells. To date more than 1000 mutations have been described in this gene, and most are rare (2). By focusing on five common mutations it is possible to detect the disease-causing mutation in ∼90% of Irish patients (3). The five mutations [and the percentages of Irish (3) and worldwide (2) cases] are F508del (77.4%, 66.0%), G551D (7.1%, 1.6%), R117H (2.7%, 0.3%), 621+1 G>T (1.4%, 0.7%), and G542X (0.5%, 2.4%). Four of these fall into the severe class of mutations in which the mRNA is incorrectly spliced (621+1 G>T), or in which the protein is not synthesized (G542X) or is blocked during processing (F508del), or its regulation is blocked (G551D).

Mutations in the CFTR gene can be detected by many mutation-detection systems, including single-strand conformation polymorphism analysis (4), restriction fragment length polymorphism analysis, Amplification Refractory Mutation System (ARMS) PCR (5), and more recently, real-time PCR systems using Sybr Green 1 (6) or hybridization probes (7). Currently, for mutation detection using hybridization probes on the LightCycler system, the detector probe is designed to overlie the possible site of the mutation. This can have drawbacks when multiplexing in the same detection channel because peaks can become merged, making genotyping of a sample difficult.

This study aimed to improve the multiplexing capabilities of real-time PCR in its use for mutation detection. To this end we used ARMS PCR primers to selectively amplify the wild-type or mutant alleles in separate reactions. Subsequent detection of PCR products was carried out with a common set of hybridization probes. The advantage …

Dynamic Object Flow Analysis (2008)

The behavior of an object-oriented software system is notoriously hard to understand from the source code alone. The main reason is the large gap between the program's static structure and its actual runtime behavior. Features inherent to object-orientation, like object aliasing and late binding, - while providing a high degree of expressiveness to model an application domain - make programs hard to understand, maintain, and analyze. Complementary to static analysis, dynamic analysis can help to close this gap by investigating the properties of a running program. The state of the art in dynamic analysis focuses on investigating runtime control flow and structures of object graphs, but a thorough analysis of how objects are passed through a system is missing. Tracking how object references are transferred, however, is essential to analyze the dependencies introduced by object aliasing. In this dissertation we propose Object Flow Analysis, our approach to track object flow by explicitly representing object references and reference transfer. Object Flow Analysis provides an effective and original way of analyzing and runtime monitoring dependencies introduced by object aliasing. To validate Object Flow Analysis, we propose three different reverse engineering applications that, based on Object Flow Analysis, reason about aliasing dependencies in object-oriented programs. Yet Object Flow Analysis extends beyond traditional reverse engineering applications. A key contribution of our work is that we advance the state of the art in back-in-time debugging by proposing and providing an implementation of the concept of Object Flow Analysis in a high-level language virtual machine.

Foreground-background segmentation using iterated distribution matching (2011)

This paper addresses the problem of image segmentation with a reference distribution. Recent studies have shown that segmentation with global consistency measures outperforms conventional techniques based on pixel-wise measures. However, such global approaches require a precise distribution to obtain the correct extraction. To overcome this strict assumption, we propose a new approach in which the given reference distribution plays a guiding role in inferring the latent distribution and its consistent region. The inference is based on an assumption that the latent distribution resembles the distribution of the consistent region but is distinct from the distribution of the complement region. We state the problem as the minimization of an energy function consisting of global similarities based on the Bhattacharyya distance and then implement a novel iterated distribution matching process for jointly optimizing distribution and segmentation. We evaluate the proposed algorithm on the GrabCut dataset, and demonstrate the advantages of using our approach with various segmentation problems, including interactive segmentation, background subtraction, and co-segmentation.
Improving the Approximation Ratio for Capacitated Vehicle Routing (2020)

We devise a new approximation algorithm for capacitated vehicle routing. Our algorithm yields a better approximation ratio for general capacitated vehicle routing as well as for the unit-demand case and the splittable variant. Our results hold in arbitrary metric spaces. This is the first improvement upon the classical tour partitioning algorithm by Haimovich and Rinnooy Kan and Altinkemer and Gavish.
An analysis of the performance of power circuit breakers using the modelling of electric arc and a radiometric system (2017)

The operation of circuit-breakers generates high frequency signals, therefore, a way to capture these signals is a radiometric system to evaluate the operation of the circuit-breaker, the greatest advantage of this method is that it\s possible the analyze the performance of the circuit-breaker without the need of any operational change to insert measuring devices. However, it was necessary to verify the results and guarantee that they are according to traditional methods, for that we modelled the electric power system of the power utility company according to international standards, however the field measurements have also shown the electric arc. Due to the electric arc it was necessary to include it in the simulations so that it was possible to analyze how reliable the radiometric system can be.
Manufacturing and actuation characterization of ionic polymer metal composites with silver as electrodes (2006)

Manufacturing and characterization of ionic polymer metal composites (IPMCs) with silver as electrodes have been investigated. Tollen's reagent that contains ion Ag(NH<sub>3</sub>)<sub>2</sub><sup>+</sup> was used as a raw material for silver deposition on the surfaces of the polymer membrane Nafion"R". Two types of inner solvents, namely common water based electrolyte solution (LiOH 1N) and ionic liquid were used and investigated. Compared to IPMCs with platinum electrodes, silver-plated IPMCs with water electrolyte showed higher conductivity. The actuation response of silver-plated IPMCs with the water based electrolyte was faster than that of platinum IPMCs. However, the silver electrode was too brittle and severely damaged during the solvent exchange process from water to ionic liquid, resulted in high resistance and hence very low actuation behavior.
Two‐dimensional maps of the cerebral cortex (1980)

A procedure is described for constructing two-dimensional, unfolded representations of the cerebral cortex. The technique is based on information contained in outlines of histological sections, and it allows an entire hemisphere to be represented on a single cortical map. Maps for different hemispheres from individuals of the same species are similar in size, shape, and organization, and their configuration is largely independent of the plane of sectioning used for reconstruction. Many types of information pertaining to the location and organization of different functional subdivisions can be displayed on cortical maps; representative applications of the technique to mapping cerebral cortex in the macaque and the cat are shown. Areal measurements on cortical maps correspond closely (generally within 20%) to actual surface areas in the intact hemisphere. Therefore, the maps can also be used to provide accurate determinations of the absolute and relative extent of various anatomical and functional subdivisions of the cortex.
Silences for Love (1998)

Here are the weary traveler &amp; one-eyed boy, Gettysburg sundown, sighs over Sarajevo &amp; massacre at the Patriarch's tomb, snowstorm canoe trip ending with a brother beneath Northern Lights-deaths &amp; weddings, reunions in companion love, Oklahoma City trail of tears, asking blessing to learn healing. Here too are long silence &amp; welcome home: in aging harlequin &amp; his gypsy, in the runes of the Two-Hearted River, in dreams &amp; visions going &amp; coming, memory of a lost friend trapped on corpse detail, rush hour traffic jam, old bridge &amp; hidden meadow, snowstorm near-death car crash, old friend fired hence with a last call for love, free clothes, &amp; newly unfurling leaf. Silences for Love also offers "skillful technique, attention to minute particulars &amp; variable foot," continuing to extend the demotic traditions of American poetry established by Walt Whitman, William Carlos Williams, and Charles Reznikoff
Analysis of Antimalarial Synergy between Bestatin and Endoprotease Inhibitors Using Statistical Response-Surface Modelling (2001)

The pathway of hemoglobin degradation by erythrocytic stages of the human malarial parasite Plasmodium falciparum involves initial cleavages of globin chains, catalyzed by several endoproteases, followed by liberation of amino acids from the resulting peptides, probably by aminopeptidases. This pathway is considered a promising chemotherapeutic target, especially in view of the antimalarial synergy observed between inhibitors of aspartyl and cysteine endoproteases. We have applied response-surface modelling to assess antimalarial interactions between endoprotease and aminopeptidase inhibitors using cultured P. falciparum parasites. The synergies observed were consistent with a combined role of endoproteases and aminopeptidases in hemoglobin catabolism in this organism. As synergies between antimicrobial agents are often inferred without proper statistical analysis, the model used may be widely applied in studies of antimicrobial drug interactions.

A 23.6 GHz sub-half-micrometer E/D MODFET divide-by-32/64 static prescaler (1992)

An application-ready prescaler with performance competitive with state-of-the-art R&D dividers was designed to be a high-performance replacement for standard ECL parts in instruments. It is fabricated in a proven self-aligned contact sub-half-micrometer GaAs-based enhancement/depletion-mode (E/D-mode) MODFET IC process that utilizes sidewall-spacer self-alignment technology to obtain 0.3-0.5 mu m gate length with conventional high-throughput contact lithography. With pseudomorphic InGaAs channels, 30 MHz to 23.6 GHz prescaler operation is demonstrated at room temperature. The performance improves at 0 degrees C, while at 70 degrees C the upper frequency typically drops by 2 GHz. Correct high-speed pulse-mode operation requires (1) presetting which does not degrade the performance and (2) suppression of self-oscillation during quiet periods between pulse bursts. The circuit design provides for both, and pulse-mode operation without ringing, or pulse loss, at 22.4 GHz (present testing limit) has been confirmed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
