Kinetics of Radical Polymerization. LII. Kinetic Investigation of Styrene Polymerization in Viscous Medium (1990)

Abstract This paper deals with the homopolymerization of the systems styrene-azobisisobutyronitrile-dibutyl phthalate-50°C and styrene-benzoin-dibutyl phthalate-50°C. The dependencies of initiation and overall rates of the polymerization on the concentrations of monomer and the viscous solvent were studied. The absolute rate constants for chain propagation and termination were determined. The termination rate constant of the styrene-dibutyl phthalate system was found to be inversely proportional to the viscosity of the medium. The propagation rate constant was found to decrease with monomer concentration, which could be evaluated quantitatively in terms of the hot radical theory.
Spectral line pairing for heterodyne OCDMA (2011)

A novel OCDMA scheme uses spectral line pairing to generate signals suitable for heterodyne decoding. Both signal and local reference are transmitted in one optical fiber and a simple balanced receiver performs sourceless heterodyne detection.
Vestibular responses to rotation in the newborn infant. (1953)

Using a newly designed rotating apparatus with control of acceleration, deceleration and speed, the response of 64 full term newborn infants to rotation was studied. While awake, all infants showed head and eye deviation opposite to the direction of rotation during acceleration and in the same direction during deceleration; all infants had a normal nystagmus during acceleration and for several turns of constant speed. Then followed a reversal of the nystagmus as soon as deceleration took place. The duration of postrotational nystagmus following 10 turns in 20 seconds varied from 3 to 35 seconds with an average of 13.1 seconds. There is no comparable adult group reported as the stimulus is not constant or controlled. Sleeping infants had no response to rotation even though they gave normal responses while awake. Associated postrotation reactions were: flushing, eructation and voiding. The literature on vestibular responses to rotation in the newborn infant has been reviewed.
Substance geology of the western desert in Egypt and Sudan revealed by Shuttle Imaging Radar (SIR-A) (1983)

A correlation of known archaeologic sites with the mapped locations of the streamcourses is expected and may lead to new interpretations of early human history in the Sahara. The valley networks, faults, and other subjacent bedrock features mapped on the SIR-A images are promising areas for ground water and mineral exploration. Additionally, the analogies between the interplay of wind and running water in the geologic history of the Sahara and of Mars are strengthened by the SIR-A discoveries of relict drainage systems beneath the eolian veneer of Egypt and Sudan.
Characterization of <i>MEL</i> genes in the genus <i>Zygosaccharomyces</i> (1994)

We cloned and sequenced a Zygosaccharomyces cidri MEL gene with a view to investigating the structure and regulation of yeast MEL genes. The amino acid sequence deduced from the nucleotide sequence showed 78.6% and 78.2% similarity to Saccharomyces cerevisiae and Saccharomyces pastorianus alpha-galactosidases, respectively. The expression of the MEL gene in several Zygosaccharomyces strains was induced by galactose. An electrophoretic karyotype of several Zygosaccharomyces species was obtained using contour-clamped electric field gel electrophoresis. The minimum number of chromosomes was five for Z. cidri, six for Z. fermentati, three for Z. florentinus, and four for Z. microellipsoides. The sizes of the chromosomes were generally larger than those of S. cerevisiae, the smallest containing approximately 0.4 megabase. The MEL gene was located, using the Z. cidri MEL gene as a probe, on the largest chromosome of the Z. cidri strains. In addition, a smaller chromosome (600 kb) in Z. cidri strain CBS4575 showed hybridization to the homologous MEL probe. This chromosome was absent in Z. cidri strain CBS5666. The probe hybridized to the largest chromosome of Mel+ Z. fermentati strains but failed to hybridize to any chromosome of Mel+ Z. mrakii or Z. florentinus strains. These results suggest the existence of a polymorphic MEL gene family in the yeast Zygosaccharomyces.
Physiosonic - movement sonification as auditory feedback (2009)

The freeze-fracture technique was used to study the structural organization of the membranes of trophozoites of the protozoon Giardia duodenalis. No special array of intramembranous particles was observed in the membrane lining the protozoon body or the flagella. A large globular protuberance located in the ventral region displayed several small circular indentations similar to those seen in the dorsal region. These also occurred on the parasite surface as revealed in fracture-flip replicas. A large number of vesicles were observed below the plasma membrane; they corresponded to an acidic compartment as indicated by fluorescence microscopy of acridine orange-stained cells and contained acid phosphatase as indicated by cytochemistry. In addition, gold-labeled macromolecules (albumin, peroxidase, transferrin, and low-density lipoprotein) accumulated in the vesicles. These observations suggest that the peripheral vesicles of trophozoites are part of the endosomal-lysosomal system of G. duodenalis.

Casa de la Lh'engua: a set of language resources and natural language processing tools for Mirandese (2014)

This paper describes the efforts for the construction of Language Resources and NLP tools for Mirandese, a minority language spoken in North-eastern Portugal, now available on a community-led portal, Casa de la Lhéngua. The resources were developed in the context of a collaborative citizenship project led by Microsoft, in the context of the creation of the first TTS system for Mirandese. Development efforts encompassed the compilation of a corpus with over 1M tokens, the construction of a GTP system, syllable-division, inflection and a Part-of-Speech (POS) tagger modules, leading to the creation of an inflected lexicon of about 200.000 entries with phonetic transcription, detailed POS tagging, syllable division, and stress mark-up. Alongside these tasks, which were made easier through the adaptation and reuse of existing tools for closely related languages, a casting for voice talents among the speaking community was conducted and the first speech database for speech synthesis was recorded for Mirandese. These resources were combined to fulfil the requirements of a well-tested statistical parameter synthesis model, leading to an intelligible voice font. These language resources are available freely at Casa de la Lhéngua, aiming at promoting the development of real-life applications and fostering linguistic research on Mirandese.
Thermoluminescence as a palaeothermometer (1984)

The results of annealing experiments on a little-metamorphosed (type 3.5) ordinary chondrite are reported. The thermoluminescence (TL) emission characteristics of the annealed samples show trends very similar to those observed in meteorites which have been naturally metamorphosed in various degrees. The trends are also similar to those observed in annealing experiments on terrestrial albite, where the changes are associated with the low-to-high temperature transformation. These results suggest that the TL phosphor in meteorites is feldspar and that TL can be used to estimate paleotemperatures for little-metamorphosed and highly unequilibrated meteorites.
Role of motor cortex in coordinating multi-joint movements: Is it time for a new paradigm? (2000)

Reaching movements to spatial targets require motor patterns at the shoulder to be coordinated carefully with those at the elbow to smoothly move the hand through space. While the motor cortex is involved in this volitional task, considerable debate remains about how this cortical region participates in planning and controlling movement. This article reviews two opposing interpretations of motor cortical function during multi-joint movements. On the one hand, studies performed predominantly on single-joint movement generally support the notion that motor cortical activity is intimately involved in generating motor patterns at a given joint. In contrast, studies on reaching demonstrate correlations between motor cortical activity and features of movement related to the hand, suggesting that the motor cortex may be involved in more global features of the task. Although this latter paradigm involves a multi-joint motor task in which neural activity is correlated with features of movement related to the hand, this neural activity is also correlated to other movement variables. Therefore it is difficult to assess if and how the motor cortex contributes to the coordination of motor patterns at different joints. In particular, present paradigms cannot assess whether motor cortical activity contributes to the control of one joint or multiple joints during whole-arm tasks. The final point discussed in this article is the development of a new experimental device (KINARM) that can both monitor and manipulate the mechanics of the shoulder and elbow independently during multi-joint motor tasks. It is hoped that this new device will provide a new approach for examining how the motor cortex is involved in motor coordination.
Lineage specific role of Ship1 in development of allergic airway inflammation (2014)

Background The PI3K pathway is a potent mediator of several functions associated with asthma pathogenesis, including supporting leukocyte survival, activation, migration and cytokine release. Proper negative regulation of this pathway is integral in order to restrict overactive immune responses. Negative regulation of PI3K is predominantly controlled by the lipid phosphatases PTEN and SHIP-1. Inpp5d (Ship1) deficient mice develop spontaneous airway inflammation and have enhanced sensitivity to allergen induced airway inflammation. We hypothesized that deleting Ship1 expression specifically in lineages known to be crucial for adaptive Th2 responses would uncover more subtle effects that could either positively or negatively regulate disease severity in a mouse model of allergic airway inflammation (AAI).
Structure and Dynamics of Distamycin A with d(CGCAAATTGGC):d(GCCAATTTGCG) at Low Drug: DNA Ratios (1990)

Two-dimensional NMR has been used to study the interaction of distamycin A with d(CGCAAATTGGC):d(GCCAATTTGCG) at low and intermediate drug:DNA ratios (less than 2.0). Drug-DNA contacts were identified by nuclear Overhauser effect spectroscopy, which also served to monitor exchange of the drug between different binding sites. At low drug:DNA ratios (0.5), distamycin A binds in two orientations within the five central A-T base pairs and has a preference (2.2:1) for binding with the formyl end directed toward the 5' side of the A-rich strand. The pattern of drug-DNA contacts corresponding to the preferred binding orientation are consistent with the drug sliding between adjacent AAAT and AATT binding sites at a rate that is fast on the NMR time scale. Similarly, the pattern of NOEs associated with the less favored orientation are consistent with the drug sliding between adjacent AATT and ATTT sites, again in fast exchange. Off-rates for the drug from the major and minor binding orientations were measured to be 2.4 +/- 1.5 and 3.3 +/- 1.5 s-1, respectively, at 35 degrees C. At intermediate drug:DNA ratios (1.3) exchange of the drug between the two one-drug and the two sites of a two-drug complex is observed. Off-rates for both drugs from the 2:1 complex were measured to be 1.0 +/- 0.5 s-1 (35 degrees C).

NUCLEON PROPERTIES IN CHIRAL COLOR DIELECTRIC MODEL (1992)

The chiral extension of color dielectric model has been used to study the static properties of nucleon. In this calculation we have treated the gluon and the pion fields perturbatively. It is found that the neutron charge rms radius and the pion-nucleon coupling constant are almost insensitive to the parameters used and are in excellent agreement with the experimental values. For better fitting the proton charge rms radius, nucleon magnetic moments and axial coupling constant prefer large quark masses (~100 MeV) and small glueball masses (<1100 MeV). The strong coupling constant is found to be very sensitive to the quark and glueball masses.
Etude de quatre facteurs de virulence de bordetella pertussis dans un modele murin d'infection respiratoire (1994)

Bordetella pertussis, l'agent de la coqueluche, synthetise plusieurs facteurs de virulence, parmi lesquels deux adhesines, la pertactine et l'hemagglutinine filamenteuse, et deux toxines, la toxine de pertussis et l'adenylcyclase-hemolysine. Leur role a ete etudie a l'aide de mutants n'exprimant pas l'un de ces facteurs dans un modele murin d'infection respiratoire, au niveau de la colonisation et des lesions pulmonaires. Nous avons montre que chacune des adhesines pouvait compenser l'absence de l'autre, mais qu'elles avaient un role dans la persistance bacterienne, suggerant l'existence d'une cooperation entre ces adhesines. A l'inverse, l'adenylcyclase-hemolysine est indispensable a la multiplication bacterienne initiale, alors que la toxine de pertussis est importante en fin d'infection. Les mutants depourvus d'une des toxines induisent peu ou pas d'inflammation pulmonaire, indiquant que ces toxines participeraient a cet effet, soit directement, soit indirectement, en inactivant les cellules immunitaires et en facilitant ainsi l'action d'autres facteurs proinflammatoires. L'etude des interactions cellulaires in vitro a revele que b. Pertussis etait cytotoxique pour les macrophages murins qui meurent par apoptose ou mort cellulaire programmee. Le mutant depourvu de toxine de pertussis est aussi actif que la souche sauvage, alors que celui qui n'exprime pas d'adenylcyclase-hemolysine n'est plus toxique, suggerant un role pour l'adenylcyclase-hemolysine dans l'apoptose des macrophages. Enfin, nous avons mis en evidence que, malgre leur efficacite contre une infection respiratoire murine par b. Pertussis, aucun des quatre facteurs synthetises par b. Pertussis ne protegeait contre une infection par bordetella parapertussis, l'autre espece pathogene pour l'homme, suggerant que cette protection serait specifique d'espece
Simian immunodeficiency virus infection in a patas monkey (Erythrocebus patas): evidence for cross-species transmission from African green monkeys (Cercopithecus aethiops sabaeus) in the wild (1996)

Socio-ethological studies on troops of African green monkeys (AGMs) (Cercopithecus aethiops sabaeus) and patas monkeys (Erythrocebus patas) in Senegal have documented physical contacts between these two species. Elevated simian immunodeficiency virus (SIV) seroprevalence rates have been reported for the different AGM subspecies. We report here the extent to which patas monkeys are infected and compare the relatedness of the viruses isolated from theses two different species. Among the 85 AGMs and 54 patas monkeys studied, 47% of 7.5%, respectively, had antibodies that cross-reacted with HIV-2 envelope proteins. From two AGMs a virus was isolated. From the patas monkeys, virus isolation was generally not possible, but from one animal that was ill a virus designated pamG31 was amplified by PCR. In addition, for the two SIVagm isolates, an 830 bp region spanning the env and nef genes was amplified and sequenced. Comparisons of sequences from the env/nef region revealed 80% identity between pam G31 and SIVagm isolates from AGMs of the sabaeus subspecies, and 94% identity between the two SIVagm isolates. Phylogenetic analysis showed that pamG31 belongs to the SIVagm sabaeus subgroup. This is the first report of a lentiviral infection in a patas monkey. The close genetic relatedness between pamG31 and SIVagm sabaeus viruses is a strong argument in favour of cross-species transmission of SIV between AGMs and patas monkeys in the wild. For these reasons, we propose to refer to this patas virus as SIVagm-pamG31.
DNA‐Mediated Assembly of Boron Nitride Nanotubes (2007)

The dispersion of nanomaterials in solutions is of primary importance for the improvement of their processability, but it also provides a way to investigate phase behavior and to assemble nanostructures in solvents. Several methods based on different interactions have been developed to disperse carbon nanotubes, whereas little development has been made for their boron nitride nanotube (BNNT) counterparts. A direct way to obtain long-range ordering may be through spontaneous nematic ordering in solutions at sufficiently high concentrations of the nanomaterial fraction. Lyotropic nematics have been observed in various organic and inorganic systems. In this work, the strong interactions between DNA and BNNTs were exploited to fabricate high-concentration BNNTs aqueous solutions by a simple method, and then, for the first time, nematic ordered ensembles of BNNTs were obtained by filtration. It is proposed that a localized liquid-crystal phase appears during filtration, as the ordering trend for the BNNTs was found to depend on the concentration of the aqueous solutions of the BNNTs. Moreover, BNNTs were successfully localized on a predefined area by using a thiol-modified DNA-BNNT hybrid.
Optical plasma resonance in semiconductors: Novel concepts for modulating far-infrared light (1989)

A novel concept for modulating far-infrared light is presented based on the ‘‘photon-plasmon, plasmon-photon’’ interaction with a thin layer of a free-electron gas in a n-doped semiconductor. For oblique incidence of p-polarized light at the plasma frequency of the electrons, high-reflection properties arise due to plasma resonance. The influence of all the constituent parameters (angle of incidence, electron mobility and density, thickness of the layer, etc.) on the reflectivity is discussed. The plasma frequency, and hence the reflectivity, can be modulated by changing the effective mass or the density of the electrons. This leads to a small, integrable, and fast modulable mirror, which can be used as a switching device (electrically or optically driven) or even as a way of frequency modulation.
Gamma rays produced by intra-cavity inverse Compton scattering of a storage ring free-electron laser (1999)

A collimated tunable gamma-ray beam has been generated by inverse Compton scattering of an additional positron bunch with the Super-ACO storage ring free-electron laser (FEL) positioned inside the optical resonator in the UV range (345-355 nm). This specific novel set-up ensures a natural transverse overlap and synchronization. The tunable gamma-ray beam produced covers the energy range from a few MeV up to 35 MeV, the maximum energy achievable with a FEL. The number of scattered gamma rays is relatively large (5000 000 photons/s at 800 MeV and 2000 000 photons/s at 700 MeV, i.e. the greatest value for a FEL). Furthermore, a significant number of high-energy gamma rays have also been produced by scattering of the spontaneous radiation stored in the optical cavity. The scattering is performed from a positron bunch outside the undulator, demonstrating for the first time the possibility of optimizing the yield and/or the spectrum by alteration of the stored beam without alteration of the FEL.
Curcumin Inhibits Neurotensin-Mediated Interleukin-8 Production and Migration of HCT116 Human Colon Cancer Cells (2006)

Neurotensin-mediated induction of tumor cell IL-8 expression and secretion may contribute to the procarcinogenic effects of neurotensin on gastrointestinal cancers. Furthermore, a potential mechanism for the chemopreventive and chemotherapeutic effects of curcumin on colon cancers may be through the inhibition of gastrointestinal hormone (e.g., neurotensin)-induced chemokine expression and cell migration.
Ghost Tomography (2018)

Ghost tomography using single-pixel detection extends the emerging field of ghost imaging to three dimensions, with the use of penetrating radiation. In this work, a series of spatially random x-ray intensity patterns is used to illuminate a specimen in various tomographic angular orientations with only the total transmitted intensity being recorded by a single-pixel camera (or bucket detector). The set of zero-dimensional intensity readings, combined with knowledge of the corresponding two-dimensional illuminating patterns and specimen orientations, is sufficient for three-dimensional reconstruction of the specimen. The experimental demonstration of ghost tomography is presented here using synchrotron hard x-rays. This result expands the scope of ghost imaging to encompass volumetric imaging (i.e., tomography), of optically opaque objects using penetrating radiation. For hard x-rays, ghost tomography has the potential to decouple image quality from dose rate as well as image resolution from detector performance.
