Published 1985Staff ViewISSN: 1365-2478Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: GeosciencesPhysicsNotes: A new deterministic technique for estimating a wavelet suggested by Loewenthal and Jakubowicz requires measurement of both pressure and vertical particle velocity. Through construction of the impedance function a deterministic estimation of the wavelet and the reflectivity can be obtained.This idea is tested for a one-dimensional model. The test is carried out by forming a synthetic seismogram of both pressure and particle velocity and checking the formulas for obtaining the estimated wavelet under noisy conditions.Type of Medium: Electronic ResourceURL: -

Published 2001Staff ViewISSN: 1365-2133Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: We report a 56-year-old Korean woman with porphyria cutanea tarda (PCT), showing multiple scarring bullae and hypertrichosis on sun-exposed areas of skin with postinflammatory hyperpigmentation. Sclerodermoid changes were also found on both hands, the face and neck. The patient had suffered from CREST syndrome, manifesting with Raynaud’s phenomenon and sclerodactyly, for more than 15 years. Anticentromere antibody was positive. She had presented with splenomegaly 3 years before the development of PCT, and was diagnosed as having idiopathic myelofibrosis, based on bone marrow biopsy. In summary, she had had CREST syndrome for 15 years and later developed idiopathic myelofibrosis and PCT. This is the first reported case of PCT in association with idiopathic myelofibrosis and CREST syndrome.Type of Medium: Electronic ResourceURL: -

Published 1989Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: We report a high-efficiency PpinN GaAs/AlGaAs waveguide phase modulator for high-speed operations. By introducing p- and n-GaAs layers beside the intrinsic GaAs layer of a P-i-N double heterostructure, the absorption edge-related effect, hardly used in P-i-N phase modulators, is utilized. We demonstrate a high phase shift efficiency of 37.5°/V mm at 1.3 μm wavelength. Although this corresponds to the highest expeirmental value reported for reverse-biased GaAs/AlGaAs phase modulators, our device operates with a low junction and a very low dynamic capacitance.Type of Medium: Electronic ResourceURL: -

Published 1990Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: We report on the fabrication and the characterization of low-loss, single-mode GaAs/AlGaAs single heterostructure ridge waveguides and a linear electro-optic phase modulator on silicon substrate. The waveguides and the phase modulator were grown by molecular beam epitaxy and were characterized at a 1.3 μm wavelength. The average TE mode propagation loss of 1.24 dB/cm, obtained for a 6-μm-wide ridge waveguide, is the lowest loss so far reported. The measured phase shift efficiency of the phase modulator was 3.5°/V mm.Type of Medium: Electronic ResourceURL: -

Published 1995Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: Free-space micro-optical systems on a chip containing three-dimensional microgratings have been demonstrated using surface-micromachining technique. The micrograting is integrated with a rotary stage, a collimating micro-Fresnel lens, and an edge-emitting laser held by three-dimensional alignment structures on a single Si substrate. Diffraction patterns for various grating rotation angles are observed. Another optical interconnect module consisting of three cascaded microgratings is also demonstrated. The micrograting is a basic building block for many micro-optical systems and is very attractive for applications in microspectrometers, free-space optical interconnect, optoelectronic packaging, and wavelength-division multiplexed integrated micro-optical systems. © 1995 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1995Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: Novel self-aligned hybrid integration of semiconductor lasers with three-dimensional micro-optical components has been demonstrated. The self-alignment structures are fabricated integrally with other three-dimensional micro-optical elements such as micro-Fresnel lenses, mirrors, and gratings on a single Si chip by surface micromachining technology. The Si substrate serves as a free-space micro-optical bench for active and passive optoelectronic components. A divergent beam emitted from an edge-emitting semiconductor laser has been successfully collimated by the integrated micro-Fresnel lens. The integration scheme offers a new approach for optoelectronic packaging and a new technology platform for integrating complete free-space micro-optical system on a single chip. © 1995 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1998Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: Exchange biasing field Hex and coercive field Hc of the exchange-biased NiO spin valves deposited over differently etched glass substrates and glass Si3N4 buffer layers were measured in order to investigate the effect of roughness at the NiO/NiFe interfaces. The magnetoresistive (MR) ratio, Hex, and Hc were not influenced by etching time, even though the rms roughness Rrms increased from 4.7 to 33 Å. However, the MR ratio, Hex, and Hc increased with Si3N4 buffer thickness, even when the Rrms had almost the same values. To explain this ambiguous dependence of Rrms, we consider an effect of the average slope of roughness instead of Rrms in an atomic force microscope image. The steep slope of roughness played an important role in Hex and Hc in NiO spin valves due to an increase in magnetostatic energy and the decrease in antiferromagnetic domain size. © 1998 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 2001Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: We report results of systematic investigation of impurities in dielectrics and hydrogen barriers (Ti and Al2O3 films) during the integration process of SrBi2Ta2O9-based ferroelectric memories. The capacitors integrated with Ti hydrogen barriers are not electrically degraded regardless of the annealing conditions of the subdielectrics. On the contrary, electrical properties of the capacitors using Al2O3 hydrogen barriers significantly depend on the annealing temperatures for subdielectrics. It turned out that interaction of the dielectrics with plasma during sputtering of the Ti films caused fragmentation of the moisture in the dielectrics and absorption of the hydrogen in the Ti films, making annealing irrelevant. However, the alumina films blocked both hydrogen and moisture in the subdielectrics during the passivation process, resulting in dependence on the annealing temperatures. © 2001 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 2000Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: We report on a hydrogen barrier necessary for a conventional passivation process of integrated SrBi2Ta2O9 (SBT)-based memories. The passivation process significantly degraded electrical properties of the memories, resulting from hydrogen damage in the SBT capacitors. Metallic films (Ti, TiN, and Al) were investigated as a hydrogen barrier during the passivation process. The Ti(〉500 Å) hydrogen barrier only showed the electrical properties of memories free from hydrogen damage. The formation of stable hydrides and the suppressed diffusion of hydrogen through the Ti films during the passivation processes resulted in sufficient switching polarization, low leakage current, and good reliabilities at high temperature. © 2000 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 2002Staff ViewISSN: 1439-0523Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: Identification and DNA polymorphism of the S-locus receptor kinasegene (SRK) was analysed by pollen tube tests, polymerase chain reaction-cleaved amplified polymorphic sequence (PCR-CAPS) and nucleotide sequencing. SRK-specific primers that can distinguish class and class II S haplotypes amplified single DNA fragments of 900-1050 bp. The DNA fragments of 22 inbred lines amplified with a class SRK-specific primer pair determined seven types with HinfI and EcoRII. In addition, the DNA fragments of 17 inbred lines amplified with a class II SRK-specific primer pair determined three types with Hinf1. Nucleotide sequencing of the DNA fragments amplified from 10S haplotypes showed that exons of the 3′-end in SRK are highly conserved, and that there is much variation of the introns, which produced polymorphism of the band pattern in PCR-CAPS profiles. The S haplotypes of the plants were determined by restriction analysis of PCR products and agreed with results based on pollen tube growth tests. The PCR-CAPS analysis using specific primer pairs of SRK is considered to be useful for S allele identification in breeding programmes.Type of Medium: Electronic ResourceURL: -

ISSN: 1360-0443Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicinePsychologyNotes: Aims. To analyse the temporal changes in demography and drug-taking behaviours of a cohort of drug users in Hong Kong . Design. An analysis of records of clients over a 5-year period . Setting. Shek Kwu Chau Treatment and Rehabilitation Centre, a large residential service offering voluntary rehabilitation programmes for male drug users in Hong Kong . Measurements. The following parameters were analysed for all admissions between 1991 and 1995: duration of drug-taking, route(s) of drug administration, type of drugs abused, practice of injection and needle-sharing, time since last needle-sharing, and expenditure on drugs . Findings. A total of 10 353 admissions were recorded in the 5-year period from 1991 to 1995, of whom 2853 (27.6%) were new admissions. The mean age was 36 years. There was a significant increase in new admission in those between the age of 13 and 19. Almost all clients were heroin users. The needle-sharing rates fell from over 20% in 1991 to 5% in 1995. Needle-sharing was more common in younger clients. The decline in the rate of needle-sharing was especially significant in those between the age of 20 and 39 . Conclusion. The proportion of young drug users in the study population in Hong Kong has risen over the 5-year period. The prevalence of high-risk drug-taking behaviours had declined, which might have contributed to the low HIV rates in the community.Type of Medium: Electronic ResourceURL: -

Published 2005Staff ViewISSN: 1365-2559Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Aims : To evaluate the different expression patterns and the prognostic significance of cell cycle regulatory molecules in diffuse large B-cell lymphomas (DLBCLs) of germinal centre (GC) and non-GC phenotypes.Methods and results : Tissue microarray slides composed of 126 extranodal and 88 nodal DLBCLs were immunostained for p16, p21, p27, p14 and p53. DLBCLs were classified into GC and non-GC phenotype according to the immunohistochemical expression of bcl-6, CD10, and MUM1. Aberrant expression of p53 was more frequent in the GC phenotype in nodal cases (P = 0.038), and the loss of p16, p21 and p14 expression was significantly more common in the non-GC phenotype (P = 0.004, P = 0.001, P 〈 0.001). Concurrent disruptions of the p16-Rb and p14-p53 pathways as represented by the immunoprofile of p16/p14/p53 (–/–/+) were associated with a poor prognosis in the GC phenotype [mean survival 31 months in the p16/p14/p53 (–/–/+) group versus 62 months in the other groups, P =0.0485].Conclusions : The expression and prognostic implications of cell cycle regulatory molecules differ between GC and non-GC phenotypes in DLBCLs. The immunoprofile of p16/p14/p53 (–/–/+) within the GC phenotype of DLBCLs can be defined as a poor prognostic subgroup.Type of Medium: Electronic ResourceURL: -
