Photoinduced chain fragment ordering in GdBa2Cu3Ox thin films (1999)

"We present Raman scattering experiments on oxygen deficient GdBa2Cu3OX thin films as a function of illumination and annealing induced oxygen disorder. Raman lines due to copper and oxygen vibrations at the end of Cu-O chains are used to monitor the existence of chain fragments, and the dynamics of chain conjunction and fragmentation. The results indicate the presence of photoassisted oxygen ordering in the material"

Phase behavior and blue-phase-III–isotropic critical point in<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mn/><mml:mo>(</mml:mo><mml:mi>R</mml:mi><mml:mo>)</mml:mo><mml:mo>−</mml:mo><mml:mo>(</mml:mo><mml:mi>S</mml:mi><mml:mo>)</mml:mo><mml:mn/></mml:math>mixtures of a chiral liquid crystal with a direct twist-grain-boundary to blue-phase transition (2000)

We have investigated mixtures of the (R) and (S) enantiomers of a chiral liquid crystal, (R)- or (S)-1-methylheptyl 3'-fluoro-4'-(3-fluoro-4-octadecyloxybenzoyloxy)tolane-4-carboxylate using high-resolution adiabatic scanning calorimetry. The pure (R) compound has a direct transition from the twist-grain-boundary to the blue phase without an intermediary chiral nematic phase. For the blue phases a different kind of phase behavior as a function of enantiomeric excess is observed, most probably related to the presence of a twist-grain-boundary-A instead of a chiral nematic phase below the blue phases. The general form of this phase diagram is compared with traditional blue-phase behavior. Furthermore a blue-phase-III-isotropic phase critical point, analoguous to that of a liquid-gas system, is observed, consistent with experimental and theoretical work recently published in this field. Finally, the effect of changing enantiomeric excess on the latent heats of the different first order phase transitions is measured and discussed.
Relationship Between Virus-Induced Cellular Deoxyribonucleic Acid Synthesis and Transformation by Simian Virus 40 (1971)

The fraction of cells in a confluent 3T3 cell monolayer induced by simian virus 40 infection to replicate deoxyribonucleic acid and divide corresponds to those cells which eventually become transformed. Virus-induced cells were partially separated from noninduced cells by sedimentation through Ficoll gradients. Three- to eightfold higher transformation frequencies were obtained with those cells that began to synthesize cellular deoxyribonucleic acid and divide shortly after simian virus 40 infection as compared to noninduced cells.

Influence of Two Salicylate Components on the Particle Size of an Oil-in-Water Emulsion with Nonionic Surfactants (1996)

This paper reports a study undertaken using techniques of static and dynamic light scattering to investigate the influence of sodium salicylate and methyl salicylate on droplet size of oil-in-water emulsions. The rates of changes were measured by determining the size and distribution of the oil droplet in the material. All emulsions showed a bimodal size distribution; the mean diameters and polydispersity were calculated from intensity. These data were analyzed with nonlinear regressions and bootstrap methodology. An amount of methyl salicylate component induced a decrease of mean diameter and standard deviation. On the contrary, sodium salicylate entailed the growth of all droplet populations and coalescence for the highest concentration.
Monitoring pH and electric conductivity in an EBPR sequencing batch reactor (2004)

This paper presents laboratory-scale experimentation carried out to study enhanced biological phosphorus removal. Two anaerobic aerobic (A/O) sequencing batch reactors (SBR) have been operated during more than one year to investigate the information provided by monitoring pH and electric conductivity under stationary and transient conditions. Continuous measurements of these parameters allow detecting the end of anaerobic phosphorus release, of aerobic phosphorus uptake and of initial denitrification, as well as incomplete acetic acid uptake. These results suggest the possibility of using pH and electric conductivity as control parameters to determine the length of both anaerobic and aerobic phases in an A/O SBR. More valuable information provided by monitoring pH and electric conductivity is the relation between the amount of phosphorus released and the conductivity increase observed during the anaerobic stages and which group of bacteria (heterotrophic or polyphosphate accumulating) is carrying out the denitrification process.

Development of a portable preconcentrator/ion mobility spectrometer system for the trace detection of narcotics (1997)

This project was supported by LDRD funding for the development and preliminary testing of a portable narcotics detection system. The system developed combines a commercial trace detector known as an ion mobility spectrometer (IMS) with a preconcentrator originally designed by Department 5848 for the collection of explosives molecules. The detector and preconcentrator were combined along with all necessary accessories onto a push cart, thus yielding a fully portable detection unit. Preliminary testing with both explosives and narcotics molecules shown that the system is operational, and that it can successfully detect drugs as marijuana, methamphetamine (speed), and cocaine based on their characteristics IMS signatures.
Human leukocyte antigen class II control of the immune response to p126-derived amino terminal peptide from Plasmodium falciparum. (2002)

We investigated the relationships between class II human leukocyte antigens (HLA) and the antibody response to Plasmodium falciparum p126 protein and to its amino-terminal portion (Nt47) in 2 malaria-endemic villages in Brazil, Colina and Ribeirinha. All people from the endemic areas had anti-p126 antibodies, and the frequencies of anti-Nt47 antibodies were similar in both communities (66% for Colina and 75% for Ribeirinha). Typing of HLA showed that Colina and Ribeirinha groups had no significant differences in HLA antigen frequencies. However, in both groups, significant associations between positive response to anti-Nt47 and presence of HLA-DR4, as well as between absence of response and presence of HLA-DR15, were observed. The predominance of positive responses to Nt47 among HLA-DR4 people was independent of the presence of any particular allele. There was no evidence for association between HLA-DQB1 alleles and antibody response to Nt47. Thus, naturally exposed people with different HLA class II antigens seem to respond differently to Nt47, indicating that the choice of relevant peptide sequences may have important consequences for subunit vaccine development.
A novel method to form conducting channels in SiOx(Si) films for field emission application (2010)

The electrical and field emission properties of SiOx(Si) films are studied. SiOx(Si) films of 40–100nm thick are obtained by plasma-enhanced chemical vapor deposition and thermal evaporation of Si powder onto Si substrates. Nanosized electrical conducting channels are formed in SiOx(Si) films by electrical conditioning at high current densities. The structures with conducting channels demonstrate increased field emission current and decreased threshold voltage compared to as-deposited SiOx(Si) films. The decrease in threshold voltage for electron field emission is explained by local enhancement of electric field. The diameters of conducting channels are estimated from the effective emission area to be in the range of 1–2nm.
OUTCOME FOLLOWING ISOLATED POLYETHYLENE LINER EXCHANGE IN REVISION TOTAL KNEE ARTHROPLASTY (2012)

Purpose The outcome following isolated liner exchange for revision knee arthroplasty, while an attractive option for its simplicity, has a mixed outcome reported in the literature. We report our experience in patients who had a minimum of two years follow-up. Method From our database we identified 44 cases in 41 patients who had an isolated liner exchange for a failed primary knee replacement. Twenty were female and the mean body mass index was 33 (range 20 to 49). The mean time to revision from their index procedure was 76 months (range 8 to 152). The mean age at revision was 69 years (range 45 to 90). Patients were assessed by use of validated quality of life questionnaires: Oxford-12, UCLA Activity Level, WOMAC and SF-12. Patients current scores were compared to pre-operative scores in 19 cases. Radiographs were assessed for polyethylene wear, osteolysis and alignment with respect to the mechanical axis. Intra-operative findings were compared to radiographic findings. Results The main clinical indication for liner exchange was polyethylene wear 73% (32/44), stiffness 11% (5/44), instability 7% (3/44), pain 7% (3/44) and failed locking mechanism 2% (1/44). Five patients had died, four patients refused to participate. Four (9%) knees were subsequently revised: two for aseptic loosening of the femoral component and two for the tibial component, between one and 12 years after liner exchange. Twenty-nine patients completed quality of life questionnaires. The mean follow-up was 58 months (range 24 to 123). Significant improvement was seen in the Oxford-12, the SF-12 physical component and all WOMAC domains. Conclusion Our revision rates are low compared to published results. When patients are selected appropriately, an isolated liner exchange can be a useful operation for the treatment of a failed primary total knee replacement.
Prediction of a protein band profile in preparative reversed‐phase gradient elution chromatography (1992)

The overloaded band profiles of lysozyme in reversed-phase preparative chromatography were recorded on a C18 chemically bonded silica column, with acetonitrile/water as the mobile phase. These experiments were carried out under isocratic conditions at 31.6, 31.9, and 32.2% acetonitrile (ACN) for loading factors up to 43% of the column saturation capacity and under linear-solvent-strength gradient-elution with gradient slopes of 0.5 and 1% ACN/min, for loading factors up to 11.3%. The adsorption isotherms of lysozyme were measured for the same solvent compositions and found to be accurately accounted for by a bi-Langmuir isotherm model.With the use of a Craig model implementation of the equilibrium-dispersive model of chromatography, the band profiles of lysozyme were calculated. An excellent agreement was observed between these calculated profiles and the experimental profiles recorded at loading factors below 5%. By contrast, band profiles calculated using a Langmuir isotherm failed to describe the experimental bands. At column loadings exceeding 8%, a slight but systematic deviation takes place between calculated and experimental profiles. It is most probably explained by the considerable concentration effect of the gradient, making the band experience phase equilibrium in a concentration range that exceeds largely the one where the isotherm data have been measured.
Une voix sans nombre: Henri Michaux aujourd'hui (1997)

La problematique de le voix recouvre, chez Michaux, l'interrogation sur le Sujet. L'A. etudie la maniere dont ce questionnement traverse l'oeuvre du poete, et souligne comment la voix, forme paradoxale et fuyante du sens, est inscription de la presence/absence de l'autre dans la parole. L'oralite et la vocalite ne sont pas alors synonymes, mais complementaires. Au final, il apparait que l'individuation devient problematique, et que la voix est le lieu specifique ou s'exprime une conception pluraliste du sujet
Retroviral genomic RNA dimer partner selection. (2005)

Retroviruses such as human immunodeficiency virus (HIV-1) and Moloney murine leukemia virus (MLV) package dimers of their RNA genome, a conformation which is beneficial for genetic recombination. Although genomic RNAs are generally identical and thus recombinants are indistinguishable from either parent, two distinct RNAs can be copackaged when virions are produced by coinfected cells. Within the cytoplasm of these cells, it has been assumed that RNA dimer partner selection is random, yielding encapsidated RNA homo- and heterodimers in Hardy-Weinberg proportions, a presumption critical for calculating retroviral recombination rates. In this thesis, MLV and HIV-1 RNA homo- and heterodimerization were examined using native Northern blotting as well as a novel RNA dimer capture assay. The results demonstrated that while HIV-1 RNAs formed homo- and heterodimers in random proportions, MLV RNAs preferentially self-associated. The resultant MLV virion population contained less than 40% of the heterodimers expected from random dimerization and indicated that MLV recombination rates have previously been underestimated. Coexpressed MLV vector RNAs which differed from each other in sequence by less than 0.1% self-associated to the same extent as RNAs that were similar only in their packaging regions, suggesting that homology sensing is not the mechanism of biased RNA homodimerization. Additionally, we explored the hypothesis that the distance between proviral templates might affect MLV heterodimer formation. To do this, genetically distinct MLV RNA transcripts were produced either from two cotransfected vectors or from a single genetic locus, and the proportions of hetero- and homo dimeric virion RNAs were monitored and compared. Unlike RNAs generated from two different templates, the RNAs transcribed from a single template dimerized at random. These findings suggest a model in which MLV RNA dimer partner selection occurs either cotranscriptionally or within a pool of transcripts near the proviral template.
Renal disease in carrier female dogs with X-linked hereditary nephritis. Implications for female patients with this disease. (1991)

Male dogs with X-linked hereditary nephritis (HN) serve as a model for studying male patients with this disease. In the present study, carrier female dogs were found to resemble female patients in showing a broad range of renal dysfunction. Of 37 carrier female dogs studied, all were healthy up to 5 years of age; however, all had proteinuria develop at 2 to 3 months, and focal segmental glomerulosclerosis (FSGS) was detected after 7 months. After 5 years, 4 of 13 dogs remained healthy and showed mild FSGS on renal biopsy; 4 had mild renal dysfunction develop and their kidneys showed extensive FSGS; 5 died prematurely of renal failure with end-stage kidneys. By immunofluorescence, using antibody to the NC1 domain of collagen type IV, segmental staining of glomerular basement membranes (GBM) was seen in all dogs before 3 to 4 years, and lesions of FSGS were negative. Thereafter, a transition to global staining of GBM was noted and lesions of FSGS became positive. Lens capsule and basement membranes in lung and choroid plexus showed discontinuous staining in two young carrier female dogs and continuous staining in one older carrier female dog. By electron microscopy, multilaminar splitting of some GBM was seen up to 4 years, and thereafter, splitting took on a compressed appearance, with the layers becoming apposed though still detectable. The authors conclude that: 1) carrier female dogs with X-linked HN are mosaics for an abnormality in the NC1 domain of GBM and other basement membranes; 2) FSGS develops in all carrier female dogs in glomerular capillary loops that possess an abnormal NC1 domain, and progresses to a variable extent in different dogs; and 3) the abnormality of NC1 in GBM of carrier female dogs appears to diminish with age, but this does not prevent progression of renal disease. Similar conclusions may apply to females with X-linked HN.
Implicit Wiener Series for Higher-Order Image Analysis (2004)

The computation of classical higher-order statistics such as\nhigher-order moments or spectra is difficult for images due to the\nhuge number of terms to be estimated and interpreted. We propose an\nalternative approach in which multiplicative pixel interactions are\ndescribed by a series of Wiener functionals. Since the functionals are\nestimated implicitly via polynomial kernels, the combinatorial\nexplosion associated with the classical higher-order statistics is\navoided. First results show that image structures such as lines or\ncorners can be predicted correctly, and that pixel interactions up to\nthe order of five play an important role in natural images.
Expression pattern of lacZ reporter gene representing connexin36 in transgenic mice (2004)

Targeted deletion of the connexin36 (Cx36) gene in the mouse genome leads to visual transmission defects, weakened synchrony of rhythmic inhibitory potentials in the neocortex, and disruption of gamma-frequency network oscillations. We have generated transgenic mice in which a reporter protein consisting of the exon1 coded N-terminal part of Cx36 fused to beta-galactosidase (N36-beta-gal) is expressed instead of Cx36. Here, we have used these mice for a detailed analysis of the reporter gene expression. By beta-gal staining of adult retina, we found expression of the lacZ reporter gene in the ganglion cell layer, in two rows of the inner nuclear layer, and in the photoreceptor layer. In the brain, beta-gal staining was present in gamma-aminobutyric acid (GABA)ergic neurons of the cerebellar nuclei, in non-GABAergic neurons of the inferior olive, in mitral cells of the olfactory bulb, and in parvalbumin-positive cells of the cerebral cortex. Outside the central nervous system, N36-beta-gal signals were detected in insulin producing beta-cells of the pancreas and in the medulla of the adrenal gland of adult Cx36(+/del[LacZ]) mice. This expression pattern suggests that Cx36 fulfills functional roles not only in several types of neurons in the retina and central nervous system but also in excitable cells of the pancreas and adrenal gland.
Fermentative production of 5′‐purine ribonucleotide (1968)

Abstract Micrococcus sodonensis KY 3765 and Arthrobacter citreus KY 3155 were found capable of accumulating IMP in media supplemented with hypoxanthine as a precursor. High concentrations of phosphate and magnesium salts were required for high yields of IMP. Manganese deficiency in the media was also essential. Excessive Mn 2+ effects were also seen in the IMP fermentation carried out with an adenineless mutant, of Cornynebacterium glutamicum . In M. sodonensis , R5P‐like substances, 5‐phosphoribose pyrophosphokinase and IMP pyrophosphorylase, were leaked out, of the cells grown in suboptimal Mn 2+ levels. This excretion was inhibited by high levels of Mn 2+ . Such a phenomenon was not noted in A. citreus. An adenineless mutant (KY 7208) of Brevibacterium ammoniagenes was found to accumulate an appreciable amount of IMP. The chemical changes in this fermentation showed that, hypoxanthine was first produced de novo , excreted, and then reconverted into IMP by a salvage pathway. When hypoxanthine was added to 7208 culture, IMP yield was increased appreciably. In fact exogenous 14 C‐hypoxanthine was incorporated into 14 C‐IMP. Subsequent experiments showed that indeed Br. ammoniagenes ATCC 6872, a parent culture of KY 7208, was able to produce IMP, GMP, and AMP, in good yield from hypoxanthine, guanine, and adenine, respectively.
Stabilization of a power system with a distributed generator by a Virtual Synchronous Generator function (2011)

The power capacity of distributed generators such as photovoltaic and wind turbine is growing, many of distributed generators are connected to a grid by inverters. The inverters are controlled by a PLL (Phase Locked Loop) in order to be synchronized with power system frequency. Power system will become unstable, if the capacity of inverter-connected-type distributed generators becomes larger and larger, because inverter frequency is controlled to follow the grid frequency. The concept of "Virtual Synchronous Generator" (VSG), which is to control inverters to behave like a synchronous generator, has been proposed. VSG has virtual inertia which is realized by an energy storage device to pretend rotor's inertia. In this paper, the control scheme of VSG is investigated which is based on the swing equation of a synchronous generator. Numerical simulation results show both ride-through capability of voltage dip and enhancement ability of grid stability.
Potyvirus Genome-Linked Protein (VPg) Determines Pea Seed-Borne Mosaic Virus Pathotype-Specific Virulence in <i>Pisum sativum</i> (1998)

The mechanism of Pisum sativum pathotype-specific resistance to pea seed-borne mosaic potyvirus (PSbMV) was investigated and the coding region determinant of PSbMV virulence was defined. Homozygous recessive sbm-1 peas are unable to support replication of PSbMV pathotype 1 (P-1), whereas biochemically and serologically related pathotype 4 (P-4) is fully infectious in the sbm-1/sbm-1 genotype. We were unable to detect viral coat protein or RNA with double antibody sandwich-enzyme-linked immunosorbent assay and reverse transcription-polymerase chain reaction in sbm-1/sbm-1 P-1-inoculated protoplasts and plants. Lack of viral coat protein or RNA in P-1 transfected sbm-1/sbm-1 protoplasts suggests that sbm-1 resistance is occurring at the cellular level and that inhibition of cell-to-cell virus movement is not the operating form of resistance. In addition, because virus products were not detected at any time post-inoculation, resistance must either be constitutive or expressed very early in the virus infection process. P-1-resistant peas challenged with full-length, infectious P-1/P-4 recombinant clones demonstrated that a specific P-4 coding region, the 21-kDa, genome-linked protein (VPg), was capable of overcoming sbm-1 resistance, whereas clones containing the P-1 VPg coding region were noninfectious to sbm-1/sbm-1 peas. VPg is believed to be involved in potyvirus replication and its identification as the PSbMV determinant of infectivity in sbm-1/sbm-1 peas is consistent with disruption of an early P-1 replication event.
