Are mobile phones safe? (2000)

Driven in part by disturbing allegations, a new wave of research in the United States and elsewhere is exploring possible links between cell phone radiation and cancer. Brain cancer, the topic of this article, is not the only health concern, but it dominates public discussion. A substantial body now exists of pertinent scientific evidence. This article discusses EM fields and research on looking for a link between them and cancer. The results of animal studies are briefly outlined. The article discusses exposure limits to RF radiation.
Atherosclerotic Disease of the Aortic Arch and the Risk of Ischemic Stroke (1994)

These results indicate a strong, independent association between atherosclerotic disease of the aortic arch and the risk of ischemic stroke. The association was particularly strong with thick plaques. Atherosclerotic disease of the aortic arch should be regarded as a risk factor for ischemic stroke and as a possible source of cerebral emboli.
Évaluation de la connaissance des femmes de 25 à 43 ans au sujet de leur propre fertilité (2016)

Contexte : la physiologie de la reproduction est enseignee au college. Comprendre la fertilite et se reperer dans son cycle est utile pour la prise en charge de l’hypofertilite, la regulation des naissances et la prise en charge de douleurs pelviennes ou de metrorragies. Quelles connaissances ont reellement les femmes ? Existe-t-il des facteurs predictifs du niveau de connaissance ? Les femmes souhaitent-elles des informations? Methode : etude descriptive transversale quantitative, dans un centre de sante a Montesson (78) et un service de pediatrie a Pontoise (95) entre decembre 2015 et janvier 2016 aupres de femmes âgees de 25 a 43 ans a l’aide d’un questionnaire, en calculant le pourcentage de reponses correctes. Un score a ete etabli pour determiner d’eventuels facteurs predictifs. Resultats : 155 questionnaires ont ete analyses. Le score en anatomie etait de 6/10. 45 femmes (29%) ont fait debuter la periode fertile avant l’ovulation. 34 femmes (22%) connaissaient le role de la glaire cervicale. 46 femmes (30%) ont donne l’âge comme raisons diminuant la fertilite. Plus de 114 femmes (74%) souhaitaient parler de fertilite avec leur gynecologue. La comparaison entre le 1er et le 4e quartile a donne : le lieu (p=0,7), l’âge (p=0,2), la nulliparite (p=0,3), le niveau d’etude (p<0,001), les rapports sexuels (p=1) et la contraception (p=0,1). 78 femmes (50%) estimaient avoir de bonnes connaissances. Conclusions : malgre ce qu’elles pensaient, les connaissances des femmes etaient mediocres surtout lorsqu’elles avaient un faible niveau d’etude. Mais elles etaient interessees par le sujet. C’est donc au medecin de penser a reexpliquer les bases de la fertilite a ses patientes.
The effect of grain-domain-size on levitation force of melt growth processing YBCO bulk superconductors (2002)

Effects of grain-domain-size (GDS) on levitation force have been directly investigated and identified in well-textured YBCO bulks. A single-grain-domain YBCO bulk (phi=30mm) was prepared by a top seeded melt growth process, then divided into two, three and four grain-domain to acquire the levitation forces of samples with different GDS. It is found that the levitation force of the samples monotonously decreases with the decreasing of the average GDS (or with the increasing of the total length grain-boundaries of the sample). The maximum levitation force for the single-grain-domain sample is about 1.68, 2.05 and 2.4 times higher than that of the samples with two, three, and four grain-domains. It is concluded that the levitation force of a single-grain-domain YBCO bulk is higher than that of samples with multi-grain-domains. It is also found that the levitation force is proportional to the average grain-domain radius, but inverse proportional to the total length of grain-boundaries of the sample, a simple physical model has been provided and well interpret the experiment results.
SepA, the major extracellular protein of <i>Shigella flexneri</i>: autonomous secretion and involvement in tissue invasion (1995)

In addition to Ipa proteins and IcsA, which are involved in entry into epithelial cells and intercellular spread, respectively, Shigella secretes a 110 kDa protein, designated SepA. We report the identification, cloning, and nucleotide sequence determination of the sepA gene, analysis of SepA secretion, and construction and characterization of a sepA mutant. The sepA gene is carried by the virulence plasmid and codes for a 150 kDa precursor. Upon secretion, which does not involve accessory proteins encoded by the virulence plasmid, the precursor is converted to a mature protein of 110 kDa by two cleavages removing an N-terminal signal sequence and a C-terminal fragment. Extensive similarities were detected between the sequence of the first 500 residues of mature SepA and the N-terminal region of IgA1 proteases from Neisseria gonorrhoeae and Haemophilus influenzae, the Tsh haemagglutinin of an avian pathogenic Escherichia coli, and the Hap protein involved in adhesion and penetration of H. influenzae. The C-terminal domain of the SepA precursor, which is not present in the secreted protein, exhibits sequence similarity with pertactin of Bordetella pertussis and the ring-forming protein of Helicobacter mustelae. Construction and phenotypic characterization of a sepA mutant indicated that SepA is required neither for entry into cultured epithelial cells nor for intercellular dissemination. However, in the rabbit ligated ileal loop model, the sepA mutant exhibited an attenuated virulence, which suggests that SepA might play a role in tissue invasion.
Long noncoding RNAs (lncRNAs) and the molecular hallmarks of aging (2014)

During aging, progressive deleterious changes increase the risk of disease and death. Prominent molecular hallmarks of aging are genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis, cellular senescence, stem cell exhaustion, and altered intercellular communication. Long noncoding RNAs (lncRNAs) play important roles in a wide range of biological processes, including age-related diseases like cancer, cardiovascular pathologies, and neurodegenerative disorders. Evidence is emerging that lncRNAs influence the molecular processes that underlie age-associated phenotypes. Here, we review our current understanding of lncRNAs that control the development of aging traits.
Characterisation and wear performance of plasma sprayed WC–Co coatings (1989)

In the present paper, an evaluation is made of the effect of the characteristics of raw materials on the characteristics of plasma sprayed WC–Co coatings and their abrasion wear performance. The raw materials and the coatings were characterised using X-ray diffraction techniques and metallography. The coatings were subjected to a standard ASTM abrasion wear test and their relative performances were explained based on their characteristics. Mainly, it was found that the coating characteristics were affected by the particle size, chemistry, phase composition, and porosity of the powder, factors which are dependent on the method of manufacture of the powder. In turn, it was found that the coating characteristics such as phase composition, porosity, and carbide size affected the abrasion wear performance. In general, it appears that better abrasion wear resistance is provided by denser coatings, which have a very fine distribution of hard phases (such as η-carbides) and an absence of softer phases.MST/790
Spectral decomposition using general linear chirplet transform (2017)

This paper introduces a new time-frequency analysis method, which is called General Linear Chirplet Transform (GLCT), into seismic data interpretation. The GLCT method is an extended form of the linear chirplet transform (LCT) by scanning the chirp rates of chirplet atoms at each time-frequency point and picking the one with the maximum projection upon seismic signals under analysis. The chirplet is a generalized wavelet with time-varying frequency and LCT is a subspace of chirplet transform encompassing short time Fourier transform (STFT) and continuous wavelet transform (CWT). Therefore, GLCT, being a generalized form of STFT and CWT as well, could adaptively fit the instantaneous frequency of seismic signals and produce higher energy concentration in the time-frequency plane without cross-terms interferences, enabling a better time-frequency resolution than STFT and CWT, particularly at the low and high frequency ends. The synthetic and the field data examples demonstrated that GLCT could produce spectral decomposition results with considerably robust and improved performance in stratigraphic visualization and hydrocarbon detection in contrast with conventional methods, making it a potential tool in reservoir characterization.

Expression of Enzymatically Active Rabbit Hemorrhagic Disease Virus RNA-Dependent RNA Polymerase in <i>Escherichia coli</i> (1998)

The rabbit hemorrhagic disease virus (RHDV) (isolate AST/89) RNA-dependent RNA-polymerase (3Dpol) coding region was expressed in Escherichia coli by using a glutathione S-transferase-based vector, which allowed milligram purification of a homogeneous enzyme with an expected molecular mass of about 58 kDa. The recombinant polypeptide exhibited rifampin- and actinomycin D-resistant, poly(A)-dependent poly(U) polymerase. The enzyme also showed RNA polymerase activity in in vitro reactions with synthetic RHDV subgenomic RNA in the presence or absence of an oligo(U) primer. Template-size products were synthesized in the oligo(U)-primed reactions, whereas in the absence of added primer, RNA products up to twice the length of the template were made. The double-length RNA products were double stranded and hybridized to both positive- and negative-sense probes.
Speckle-free reconstruction in digital holography (1989)

Generally, speckles impair the reconstruction of digital and optical holograms of diffusely scattering objects. With the help of an iterative method, it is possible to introduce diffusers in digital holography that do not suffer from this disadvantage. Optically obtained speckle-free reconstructions of digital holograms are presented.
Selectivity for Complex Shapes in Primate Visual Area V2 (2000)

To explore the role of visual area V2 in shape analysis, we studied the responses of neurons in area V2 of the alert macaque using a set of 128 grating and geometric line stimuli that varied in their shape characteristics and geometric complexity. Simple stimuli included oriented bars and sinusoidal gratings; complex stimuli included angles, arcs, circles, and intersecting lines, plus hyperbolic and polar gratings. We found that most V2 cells responded well to at least some of the complex stimuli, and in many V2 cells the most effective complex stimulus elicited a significantly larger response than the most effective bar or sinusoid. Approximately one-third of the V2 cells showed significant differential responsiveness to various complex shape characteristics, and many were also selective for the orientation, size, and/or spatial frequency of the preferred shape. These results indicate that V2 cells explicitly represent complex shape information and suggest specific types of higher order visual information that V2 cells extract from visual scenes.
Automated Fiber Placement Head for Manufacturing of Innovative Aerospace Stiffening Structures (2016)

In the research project “High-performance Production of CFRP Structures” (HP CFK) a new automated fiber placement (AFP) system for laying thermoset CFRP (carbon fiber-reinforced plastic) slit tapes was developed. Its novel, modular designed laying head faces current industrial needs and challenges of prospective carbon light weight applications, e. g. future aerospace stiffening structures. Thus, its compaction unit is optimized for producing complex-curved structures. To allow approximating slopes on curved geometries, it consists of several height-adjustable rollers which, in addition, are each pressure controlled to enable an individual compacting pressure for the lay-up on materials with different compression strength (e. g. foams, metals). Furthermore, the design of the laying heads cutting unit aided the manufacturing of complex structures while being located as near as possible to the nip point to allow very short minimum placement paths. This paper introduces into the general design of the modular laying head as well as preliminary results of validation studies regarding several process limits.
Intrusive Stops in Nasal-Fricative Clusters: An Aerodynamic and Acoustic Investigation (1979)

An aerodynamic investigation of the occurrence of intrusive stop consonants occurring in nasal-fricative consonant clusters in English revealed that intrusive stops were cued perceptually by silent gaps often followed by burst releases preceding the fricative consonant. In articulatory-aerodynamic terms, intrusive stops appear to result from a prolonged oral occlusion of the nasal stop which is released with a vigorous burst release just prior to complete formation of the following fricative slit constriction.

Atmospheric tarnishing of silver-plated laser mirrors (1997)

Purified air is being considered as a cost-effective alternative to evaporated liquid nitrogen for cooling laser amplifiers in the National Ignition Facility (NIF). Atmospheric corrosion of the associated flashlamp reflectors could cause significant degradation of overall laser performance. Therefore, a comprehensive study has been undertaken to address this important problem. Specific contributions include: (1) a detailed literature search, with a critical analysis of published data; (2) Predictive calculations based on the published data, as well as new measurements made a Lawrence Livermore National Laboratory (LLNL); (3) Analyses of proposed coolant gases to determine the actual concentrations of H2S, SO2, COS, CS2, H2O, NO2, Cl2, and organic forms of sulfur; and (4) Investigations of both ultra-filtration of air and protective optical coatings as possible means of preventing mirror tarnish.

<title>Identifying impact load in composite plates based on distributed piezoelectric sensor measurements</title> (1996)

This paper presents a computer code, IDIMPACT, based on a proposed impact load identification method for identifying both the amount of the impact load and its location in composite plates from distributed build-in piezoelectric sensor measurements. The proposed method consists of a system model characterizing the dynamic response of composite plates and of a response comparator estimating the impact location and force history by comparing the sensor measurements with the simulated ones. To verify the computer code and the proposed method, instrumented hammer impact tests were conducted on a 36-inch-by-30-inch composite plate with distributed surface-mounted piezo-ceramic sensors. The computer code was implemented in a PC with data acquisition boards to digitize the sensor measurements. The code would automatically run and graphically display the predicted location and impact force-time history from a monitor. The code has reliably with high accuracy predicted the force and location of every impact event that was tested.
Pituitary Adenylate Cyclase-Activating Polypeptide Gene Expression Regulated by a Testis-Specific Promoter in Germ Cells during Spermatogenesis* (2000)

Pituitary adenylate cyclase-activating polypeptide (PACAP) is a member of the glucagon-related family of hormones that is widely expressed in various tissues. The PACAP messenger RNA (mRNA) and protein is expressed at high levels in the germ cells of the testis, where it locally activates cAMP-coupled receptors located in the somatic Sertoli cells. The PACAP mRNA expressed specifically in the testis is shorter than the mRNA expressed in hypothalamus and includes 127 nucleotides of novel sequence at the 5'-end, suggesting a different start site of transcription in the testes and the utilization of a tissue-specific promoter. Here we present evidence that a single PACAP gene uses a testis-specific promoter to express a mRNA containing a unique exon located 13.5 kb upstream from the first coding exon. As determined by RT-PCR analysis of testis mRNA, the expression of the first testis-specific exon is relatively specific for the testis, as no PACAP mRNA containing the testis-specific first exon was detected in hypothalamic mRNAs. The promoter for the testis-specific PACAP gene was cloned, and a start site for transcription was mapped by primer extension. The testis-specific promoter sequence directs germ cell-specific expression upon transfection of promoter-transcriptional reporter plasmids to populations of testicular cells in vitro and upon expression of a promoter-reporter transgene in mice. Analyses of PACAP gene expression during the spermatogenic cycle, accomplished by RT-PCR of segments of isolated seminiferous tubules, identified intense expression in the postmeiotic round spermatids during developmental stages I-VIII. These observations establish the existence of a specialized PACAP gene promoter whose activity is highly regulated during the spermatogenic cycle.
Paracrine endothelin signaling in the control of basal cell proliferation in guinea pig tracheal epithelium. (1998)

Immunofluorescent analyses revealed distinct cellular/subcellular localization of endothelin (ET) receptors and ET-1 in the epithelial cell layer of guinea pig trachea. ETA was expressed predominantly in the basal cells. ETB was expressed predominantly in the ciliated columnar cells and was polarized at the apical side of the cell body within the cells. Anti-ET-1-immunoreactive cytoplasmic granules were contained in the secretory cells that were scattered throughout the epithelial layer. Cell proliferation assays with immersion cultures of differentially plated cells (basal cell-enriched, non-basal cell-enriched and mixed cell cultures) indicated the presence of paracrine ET-1 signaling pathways that transmit both positive and negative effects on the basal cell proliferation. Direct activation of ETA expressed on the basal cells caused enhancement of their growth, whereas that of ETB expressed on the ciliated columnar cells caused suppression of the basal cell growth. The latter effect was transmitted by nitric oxide whose production was stimulated by ETB activation. Furthermore, blockade of either ETA or ETB compromised the epithelial cell layer formation under the air-interphase culture, which indicates the dependence of tracheal epithelial remodeling on a balance between the positive and negative effects of ET-1 on the basal cell growth.
Diverse service architectures using alternate AIN elements (2002)

The authors consider service architectures for the advanced intelligent network (AIN) using different service logic node topologies, including most of the combinations that are planned for deployment between 1990 and 1993. Specifically, a small but well understood set of services is discussed, and the realization of these services using different physical implementations (e.g. service control points, adjunct, service nodes) is investigated. Implementation of these services on each architecture is considered on a case-by-case basis, including interworking with relevant network entities (e.g., SSP, or service switching point, and SMS, or service management system). The ability of each type of architecture to support these particular services is discussed. The ability of all of the architectures to provide any service is also stressed. The authors conclude by identifying situations and offering recommendations as to where a particular architecture type would be to the service's advantage.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
<b>Identification of macrophage migration inhibitory factor in murine neonatal calvariae and osteoblasts</b> (1996)

Bone resorption and formation are dynamic processes that occur in both normal and injured bone tissues. Regulation of these processes is mediated at the local level by cytokines and growth factors. Macrophage migration inhibitory factor (MIF) is one of the proinflammatory cytokines that activates macrophages and regulates production of other cytokines, such as tumour necrosis factor-alpha and interleukin-1. We here demonstrate, by reverse transcription-polymerase chain reaction, high expression of MIF mRNA in murine osteoblasts obtained from mouse neonatal calvariae and murine osteoblastic MC3T3-E1 cells. The presence of MIF protein in the osteoblasts was confirmed by Western blot analysis using anti-rat MIF antibody. Moreover, the immunohistochemical study revealed that MIF was localized largely in the cytoplasm. The pathophysiological function of MIF remains undefined; however, the present results suggest that MIF takes part in the osseous metabolism as well as in immunological events.
