Separation of ethylene from ethane by supported liquid membranes containing silver nitrate as a carrier. (1986)

Experimental results for the facilitated transport of ethylene through supported liquid membranes containing silver nitrate as a carrier are presented. The selectivity factor in the separation of ethylene and ethane increases with increasing carrier concentration, reaching about 1000 when silver nitrate concentration is 4mol/dm3. An approximation method for calculating the rate of facilitated transport accompanied by an instantaneous reversible reaction is proposed. This method is applicable even to the case where the diffusivities of the carrier and the complex differ from each other. It is found that the effect of experimental condition on the permeation rate of ethylene is satisfactorily explained by assuming that the reaction between ethylene and Ag+ is instantaneous and reversible
First Report of the Stapled Mesh Stoma Reinforcement Technique in a Urologic Context (2014)

Parastomal hernia is a common complication of ileal conduit formation. Mesh repair of parastomal hernia has lower rate of recurrence than nonmesh techniques but can be time-consuming to perform. The stapled mesh stoma reinforcement technique (SMART) is a novel method of rapidly constructing a reinforced stapled stoma. We report the first case utilising this technique in a urologic context. The procedure was performed on a middle-aged female with recurrent parastomal hernia of her ileal conduit. There were no perioperative complications. The resited stoma remained healthy and functioned normally. Longer term data is clearly desirable though this technique deserves consideration in the treatment of urologic parastomal hernias. This case demonstrates that SMART is an easy and convenient procedure for parastomal hernia repair.
Waveguiding properties of surface states in photonic crystals, physics/0510273 (2006)

This Licentiate presents the main results of theoretical study of light propagation in photonic structures, namely lasing disk microcavities and photonic crystals. In the first two papers (Paper I and Paper II) we present the developed novel scattering matrix technique dedicated to calculation of resonant states in 2D disk microcavities with the imperfect surface or/and inhomogeneous refractive index. The results demonstrate that the imperfect surface of a cavity has the strongest impact on the quality factor of lasing modes. The generalization of the scattering-matrix technique to the quantum-mecha- nical case has been made in Paper III. That generalization has allowed us to treat a realistic potential of quantum-corrals (which can be considered as nanoscale analogues of optical cavities) and to obtain a good agreement with experimental observations. Papers IV and V address the novel effective Green's function technique for studying propagation of light in photonic crystals. Using this technique we have analyzed characteristics of surface modes and proposed several novel surface-state-based devices for lasing/sensing, waveguiding and light feeding applications.
Software-reliability growth model: primary-failures generate secondary-faults under imperfect debugging (1994)

Little work has been done on extending existing models with imperfect debugging to the more realistic situation where new faults are generated from unsuccessful attempts at removing faults completely. This paper presents a software-reliability growth model which incorporates the possibility of introducing new faults into a software system due to the imperfect debugging of the original faults in the system. The original faults manifest themselves as primary failures and are assumed to be distributed as a nonhomogeneous Poisson process (NHPP). Imperfect debugging of each primary failure induces a secondary failure which is assumed to occur in a delayed sense from the occurrence time of the primary failure. The mean total number of failures, comprising the primary and secondary failures, is obtained. The authors also develop a cost model and consider some optimal release-policies based on the model. Parameters are estimated using maximum likelihood and a numerical example is presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Automatic rotation and zooming in mobile roadmaps (2006)

The aim of this research was to explore the navigational effects of two common features in current mobile roadmap systems: automatic rotation based on the vehicle's direction of movement and speed-dependent automatic zooming. 12 subjects tried four different visualization techniques for a mobile map in real traffic: no rotation/constant zooming, no rotation/automatic zooming, automatic rotation/constant zooming, and automatic rotation/automatic zooming. The subjects rated the techniques on four scales: position knowledge support, direction knowledge support, identification of real-world objects based on map objects and an overall score. The results showed that conditions involving automatic rotation and/or zooming got systematically more positive ratings on all scales than the conditions without those features. The implementation of automatic zooming created for this experiment was rated as very close to optimal. These results suggest that both automatic rotation and automatic zooming can enhance navigation when implemented to a mobile roadmap.

Hello Stranger! A Study of Introductory Communication Structure and Social Match Success (2009)

Social matching systems recommend people to people. One of the key challenges such systems face is how to build introduction mechanisms that minimize privacy concerns, while maximizing the chance of successful introductions. Another challenge is to design systems that are suitable for mobile devices. We explored the relationship between introduction success and four communication interfaces: 1) a simple chat interface, 2) a restrictive profile exchange interface, 3) a hybrid of the two with temporary profile information, and 4) a hybrid of the two with full profile information. Our findings show that the restrictive profile, which is suitable for mobile devices, supported a comparable level of willingness-to-meet as did the other conditions but it did so in a considerably shorter time. Users preferred the UI of the fourth condition which suggests a future development direction for introduction system user interfaces. We discuss the implications of this finding for design of mobile social-matching applications
Identifying speakers in children's stories for speech synthesis (2003)

Choosing appropriate voices for synthesizing children’s stories requires text analysis techniques that can identify which portions of the text should be read by which speakers. Our work presents techniques to take raw text stories and automatically identify the quoted speech, identify the characters within the stories and assign characters to each quote. The resulting marked-up story may then be rendered with a standard speech synthesizer with appropriate voices for the characters. This paper presents each of the basic stages in identification, and the algorithms, both rule-driven and data-driven, used to achieve this. A variety of story texts are used to test our system. Results are presented with a discussion of the limitations and recommendations on how to improve speaker assignment in further texts.
Novel Bioluminescent Quantitative Detection of Nucleic Acid Amplification in Real-Time (2010)

The combined chemistries of the BART reporter and amplification require only a constant temperature maintained by a heating block and are shown to be robust in the analysis of clinical samples. Since monitoring the BART reaction requires only a simple light detector, the iNAAT-BART combination is ideal for molecular diagnostic assays in both laboratory and low resource settings.
A new strategy for the synthesis of methacrylate end‐functionalized macromonomers by ATRP (2010)

Abstract The influence of the polymerization temperature, the [CuBr] 0 /[PMDETA] 0 ratio, and the monomer conversion on the chain‐end functionality of poly(ethyl acrylate)s (PEAs) was studied during the atom transfer radical polymerization (ATRP) of ethyl acrylate (EA) using CuBr/ N,N,N ′, N ′, N ″‐pentamethyldiethylenetriamine (PMDETA) as a catalyst system and ethyl‐2‐bromo‐2‐methylpropionate (EBiB) as an initiator. The presence of bromine chain‐end of PEA was checked by MALDI‐TOF spectrometry and by chain‐extension reaction. It was shown that ATRP of EA performed with [EA] 0 /[EBiB] 0 /[CuBr] 0 /[PMDETA] 0 ratios of 25/1/0.5/0.5 in toluene at 50 °C allows to obtain a quantitative functionality of halide end‐groups of PEA up to 66% monomer conversion. Well‐defined poly(ethylene oxide)‐ b ‐poly(ethyl acrylate) PEO‐ b ‐PEA bearing bromide chain‐ends were obtained by the ATRP of EA using PEO‐Br as a macroinitiator under previous experimental conditions. A more detailed study of PEO‐ b ‐PEA block copolymers synthesis was previously published (Piogé et al., Macromolecules 2009, 42, 4262–4272). These end‐groups were transformed into methacrylate end‐groups by a two‐step pathway. An original approach to generate hydroxyl end‐groups was based on the nucleophilic substitution of the halogen end‐groups using different mercaptoalcohols. Using 6‐mercaptohexan‐1‐ol, a quantitative functionalization was observed. In a second step, hydroxyl groups were esterified quantitatively with methacryloyl chloride, and the resulting methacrylate end‐functionalized PEO‐ b ‐PEA macromonomers have well‐defined molecular weights and low polydispersities. © 2010 Wiley Periodicals, Inc.

Dynamic Resonant Matching Method for a Wireless Power Transmission Receiver (2015)

Wireless power transmission systems can be optimized by matching the resonance frequency of a receiver. However, in certain applications, such as, e.g., a multireceiver system, it is desired to match the individual resonance frequencies of the receiver to a fixed (e.g., common) operation frequency. In this publication, a method is proposed to match the resonant frequency dynamically without changing the physical value of the components. Instead, it is changed “virtually” by a method, which is named “frozen resonance state” by the author. The basic idea is to maintain the state of a resonant circuit (to “freeze” the state) for a fraction of the resonant period, e.g., by freewheeling the current of the resonant inductor or maintaining the voltage of the resonant capacitor. This additional time extends virtually the resonant period leading to an effective lower resonant frequency. By adjusting the additional time, the effective resonant frequency can be matched to the operation frequency individually for each receiver. This publication explains the basic idea more in detail and gives an overview of the different possible circuit topologies. Furthermore, the method is applied to an exemplary receiver of a capacitive wireless power transmission system, where measurements are presented.
Second-harmonic generation studies of differences in molecular orientation of Langmuir–Blodgett films fabricated by vertical and horizontal dipping techniques (1993)

Second-harmonic generation (SHG) studies have been carried out on Langmuir–Blodgett films of 2-docosyl-amino-5-nitropyridine that were transferred by two different dipping techniques: vertical y-type and horizontal x-type depositions. The SHG behavior of horizontally transferred films is remarkably different from that of the vertically transferred films. In y-type films the SHG is due mainly to the in-plane component χyyy(2) (which is along the dipping axis) of the second-order nonlinear optical susceptibility tensor and χxxx(2) is negligible. In the case of x-type films, the SHG is due to the in-plane χ(2) tensor components but χyyy(2) and χxxx(2) have comparable magnitudes. In both films the nonlinear optical chromophores lie almost flat with respect to the plane of the substrate. The cancellation of χxxx(2) in y-type films is due to the preferential orientation of molecular domains along the dipping axis. In horizontally transferred films, molecular domains seem to be randomly distributed on the surface.
Cleavage of Host Keratin 8 by a Chlamydia-Secreted Protease (2004)

Chlamydiae have to replicate within a cytoplasmic vacuole in eukaryotic cells. Expansion of the chlamydia-laden vacuole is essential for chlamydial intravacuolar replication, which inevitably causes host cell cytoskeleton rearrangements. A cleavage fragment of keratin 8 corresponding to the central rod region was detected in the soluble fraction of chlamydia-infected cells. Since keratin 8 is a major component of the intermediate filaments in simple epithelial cells, cleavage of keratin 8 may increase the solubility of the host cell cytoskeleton and thus permit vacuole expansion in chlamydia-infected cells. A chlamydia-secreted protease designated CPAF (chlamydial protease/proteasome-like activity factor) was both necessary and sufficient for keratin 8 cleavage in chlamydia-infected cells, suggesting that chlamydiae have evolved specific mechanisms for modifying the host cell cytoskeleton.
Noise Dressing of Financial Correlation Matrices (1999)

We show that results from the theory of random matrices are potentially of great interest to understand the statistical structure of the empirical correlation matrices appearing in the study of multivariate time series. The central result of the present study, which focuses on the case of financial price fluctuations, is the remarkable agreement between the theoretical prediction (based on the assumption that the correlation matrix is random) and empirical data concerning the density of eigenvalues associated to the time series of the different stocks of the S 500 (or other major markets). In particular, the present study raises serious doubts on the blind use of empirical correlation matrices for risk management.
Ultrasensitive system for the real-time detection of H 2 O 2 based on strong coupling in a bioplasmonic system (2012)

We theoretically investigate the dependence of the different parameters of an optical biosensor for the detection of Hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) based on absorption enhancement of Cytochrome <i>c</i> molecules near gold nanoparticles. H<sub>2</sub>O<sub>2</sub> is a major reactive oxygen species which is involved in signaling pathways and oxidative stress in cells. We use the Green's function approach as well as confirm the corresponding simulation results using the surface integral formulation. Further we show that this technique can be applied for detection of other small molecules, like oxygen and carbon monoxide.
Impulse testing of power transformers using the transfer function method (1988)

The transfer function of a transformer winding is deconvoluted in the frequency domain from the digitally recorded neutral current and high voltage applied during impulse tests. The integrity of the winding insulation is determined by comparing the transfer function obtained at full and reduced test voltage. Differences between the transfer function plots reveal local breakdowns in the winding that can be dissociated from partial discharges. Thus the method permits unambiguous acceptance or rejection if the transformer and, since the transfer function is theoretically immune to changes in the applied impulse, also allows evaluation of the chopped-impulse test. Some 100 windings of large HV power transformers have been tested using the transfer function method, which on several occasions has revealed transformer faults as well a test setup problems that would have been missed or misinterpreted by conventional techniques.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Hydrogen production and deuterium-proton exchange reactions catalyzed by <i>Desulfovibrio</i> nickel(II)-substituted rubredoxins (1988)

The nickel tetrahedral sulfur-coordinated core formed upon metal replacement of the native iron in Desulfovibrio sp. rubredoxins is shown to mimic the reactivity pattern of nickel-containing hydrogenases with respect to hydrogen production, deuterium-proton exchange, and inhibition by carbon monoxide.
Transposon Tn917PF1 mutagenesis in Bacillus licheniformis (1994)

The plasmid pTnPFl containing the transposon Tn917PF1 was introduced into the protoplasts of two Bacillus licheniformis strains in the presence of polyethylene glycol. Transpositions were produced at high temperature which inhibited plasmid replication and kanamycin was used for selection.Transposon Tn917PF1 was inserted randomly into the bacterial chromosome,producing different auxotrophic, prophage BLF and bacitracin-non-producing mutants. The auxotrophic mutant phenotypes were characterized by the Holliday-test and some mutations by hybridization with a transposon DNA probe. Insertions for the entire chromosome or for the prophage genophore were found at random, but preferred target sites were detected within limited regions, like the bacitracin synthetase or sulphate reductase genes. The partial physical map of the chromosomal region of bacitracin synthetase was constructed based on the hybridization patterns of insertion mutants.
Cation Diffusion Coefficients and Vacancy Densities in Mn-Zn Ferrites (1967)

Cation diffusion in Mn-Zn ferrites having excess iron was investigated by means of the isotope tracer method using single and polycrystalline samples. In polycrystalline samples “volume diffusion” and “grain boundary diffusion” were observed and separated from each other. The results are: (1) The volume diffusion coefficient of 59 Fe varied with the oxygen content, i.e. , the density of cation vacancies in the sample. Activation energy of the diffusion was 1.50±0.05 eV, being independent of the vacancy density. This value means the migration energy of vacancies. (2) The volume diffusion coefficients obtained were same for 54 Mn, 59 Fe, 60 Co and 65 Zn, but slightly different for 45 Ca. (3) The grain boundary diffusion coefficient was as sensitive as the volume diffusion coefficient to sintering atmospheres.

Fibroblast growth factor receptor expression reflects cellular differentiation in human oral squamous carcinoma cell lines (1998)

This study examined the expression of fibroblast growth factor receptor 2 (FGFR 2) splice variants, IIIb and IIIc, in normal and malignant human oral keratinocytes and in normal oral fibroblasts by RT-PCR using both exon-specific primers and primers common to both FGFR 2 isoforms. Fibroblasts expressed exclusively FGFR 2/IIIc whilst the normal and malignant keratinocytes co-expressed FGFR 2/IIIb and FGFR 2/IIIc. Well-differentiated keratinocytes expressed proportionally more FGFR 2/IIIb than IIIc whereas the poorly-differentiated cells expressed more FGFR 2/IIIc than IIIb. The normal and malignant keratinocytes, but not fibroblasts, expressed an additional amplification product, which consisted of both IIIb and IIIc of FGFR 2 joined by an extra base pair and with the intronic sequence removed. The results indicate that the expression of FGFR 2 isoforms reflects the degree of cellular differentiation in normal and malignant human oral keratinocytes and that receptor complexes of FGFR 2/IIIb and IIIc may regulate ligand-receptor interactions.
Organic-inorganic interpenetrating polymer networks and hybrid polymer materials prepared by frontal polymerization (2013)

Novel polyacrylamide-based hydrogels containing 3-(trimethoxysilyl)propyl methacrylate and/or tetraethoxy silane were synthesized by means of frontal polymerization, using ammonium persulfate as initiator, N,N′-methylene bisacrylamide as crosslinking agent and dimethyl sulfoxide as solvent. The obtained samples were treated at pH of 2 or 5 to induce the sol–gel reaction and evaluate their swelling behavior in the conditions. The occurrence of this reaction was assessed by solid-state NMR. Moreover, the thermal properties of the dry materials were studied by differential scanning calorimetry and thermal gravimetric analysis, and their water-contact angles were measured. It was found that the amount of Si affects the extent of swelling and the hydrophilicity of the resulting materials. © 2013 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.
