    Notes: The lightest density of Mg has stimulated renewed interest in Mg based alloys forapplications in the automotive, aerospace and communications industries. However, Mg in the pureform has relatively low strength, limited ductility and is susceptible to corrosion. Great efforts havebeen made to improve the mechanical properties of Mg alloys. Alloying Mg with other elements isone of the most important methods. An important class of Mg alloys is the Mg-Zn-RE system (RE =rare earth elements). In recent few decades, a series of new Mg-Zn-RE system alloys have beenobtained, and detailed the structure and mechanical properties of the alloys. In this paper, the structureand mechanical properties of the Mg-Zn-RE alloys have been summarized. It showed that these alloyshave high strength and they are prospected to be widely used in the future

    VerSe: A Vertebrae labelling and segmentation benchmark for multi-detector CT images (2021)
    Details
    Publication Date: 2023-03-20
    Description: Vertebral labelling and segmentation are two fundamental tasks in an automated spine processing pipeline. Reliable and accurate processing of spine images is expected to benefit clinical decision support systems for diagnosis, surgery planning, and population-based analysis of spine and bone health. However, designing automated algorithms for spine processing is challenging predominantly due to considerable variations in anatomy and acquisition protocols and due to a severe shortage of publicly available data. Addressing these limitations, the Large Scale Vertebrae Segmentation Challenge (VerSe) was organised in conjunction with the International Conference on Medical Image Computing and Computer Assisted Intervention (MICCAI) in 2019 and 2020, with a call for algorithms tackling the labelling and segmentation of vertebrae. Two datasets containing a total of 374 multi-detector CT scans from 355 patients were prepared and 4505 vertebrae have individually been annotated at voxel level by a human-machine hybrid algorithm (https://osf.io/nqjyw/, https://osf.io/t98fz/). A total of 25 algorithms were benchmarked on these datasets. In this work, we present the results of this evaluation and further investigate the performance variation at the vertebra level, scan level, and different fields of view. We also evaluate the generalisability of the approaches to an implicit domain shift in data by evaluating the top-performing algorithms of one challenge iteration on data from the other iteration. The principal takeaway from VerSe: the performance of an algorithm in labelling and segmenting a spine scan hinges on its ability to correctly identify vertebrae in cases of rare anatomical variations. The VerSe content and code can be accessed at: https://github.com/anjany/verse.

    Nonlinear behavior of magnetic surface waves on the interface between ferromagnet and antiferromagnet (2000)
    [S.l.] : American Institute of Physics (AIP)

    Notes: In this article the nonlinear frequency characteristics of the transverse magnetic surface waves at microwave frequencies on the interface between a ferromagnet and an antiferromagnet have been studied. The results show that the magnetic surface waves have passband(s) and stopband(s), which are interchangeable through the variation of the wave power. It is shown that the nonlinear surface waves excited on the interface can be backward surface waves with group velocities opposite to their phase velocities in direction. The passband widths of the forward surface waves are about five times larger than those of the backward surface waves in the situation. © 2000 American Institute of Physics.

    Slip sliding away: A novel head–disk interface and its tribology (invited) (2000)

    Notes: The continuous reduction of head–disk spacing has made the use of supersmooth media a necessity in gaining ultrahigh magnetic recording areal density. To overcome the stiction barrier associated with supersmooth disks without compromising the head flyability requirement, texture features can be transferred from the disk surface to the slider surface, creating a new type of head–disk interface, the padded slider interface. The tribology of a padded slider interface is in many ways different from that of the traditional head–disk interface with texture on the disk only. In this article, various unique tribological aspects of the padded slider interface are discussed in detail. Both theoretical modeling results and experimental data are presented to elucidate the stiction, friction, and wear behaviors of this novel head–disk interface. It is shown that the padded slider technology offers a viable alternative to the ramp load technology as a head–disk interface solution for the ultrahigh areal density. © 2000 American Institute of Physics.

    A study of dynamic friction at the head–disk interface (2000)

    Notes: With its precisely controlled contact geometry, the head–disk interface with laser zone texture affords a model system for the study of dynamic friction. By using two types of head sliders, i.e., the conventional slider and the padded slider, and a matrix of hard disks with a wide range of laser zone texture parameters, head–disk contacts involving a small number as well as a large number of bumps are realized. A rich variety of dynamic friction behavior is observed with respect to bump height and bump density dependence. A satisfactory explanation of these friction behaviors requires that both the deformational component and the adhesive component of friction be considered on equal footings. © 2000 American Institute of Physics.

    Optimized compact secondary electron collector with 100% collection efficiency for focused ion beam systems (1998)

    Notes: This article describes the optimization procedure to design a compact scintillator which has a maximum secondary electron collection efficiency without the need of a bias voltage for a focused ion beam (FIB) system. The optimized scintillator design was proven to be very effective for focused ion beam systems. By doing design optimization theoretically and experimentally, a 100% collection was realized for a simple, compact and robust scintillator structure without the bias voltage. So far our experimental study is within the scope of FIB imaging, but we have reasons to believe that the optimized designs or the optimization methodology discussed in this article should be useful in other charged particle applications such as scanning electron microscopy or wherever a scintillator is used to collect secondary electrons. © 1998 American Institute of Physics.

    Probing nanodefects in fused silica by near-field scanning optical microscopy (1998)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 84 (1998), S. 3016-3019

    Notes: Nanodefects were artificially introduced into a fused silica surface by nanoindenting with a commercial atomic force microscope. The sample was illuminated in a total internal reflection configuration and evanescent waves were detected by a near-field scanning optical probe in the constant tip-sample separation mode. The observed contrast in optical images was attributed to the strain fields associated with the nanoindents. Thus the optical image directly maps out the strain distributions associated with these nanoindents. Optical images were taken at different polarizations of the incident light (s and p). Due to different field distributions near the sample surface for the two polarizations, strain distributions at different depths were probed. The spatial resolution of this technique was limited by the probe aperture size and detector sensitivity. This technique may be a useful tool to study laser-induced damage mechanisms in optical materials at the submicron scale.

    Direct measurement of refractive-index dispersion using a time-delayed technique (1998)

    Notes: We describe a new way to measure the refractive index of dielectric materials using a time-resolved correlation method. By measuring the time delay of femtosecond pulse trains through a dielectric material, we obtain the refractive index of the material. This technique is direct, less surface sensitive, and precise to four digits. Consequently, it gives a true bulk index value. We apply this technique to measure the refractive index of fused silica, InP, and GaAs in the near infrared spectral regime. © 1998 American Institute of Physics.

    Brain CRMP Forms Heterotetramers Similar to Liver Dihydropyrimidinase (1997)

    Notes: Abstract: The cytoplasmic collapsin response mediator protein CRMP62 is involved in the signaling cascade initiated by collapsin-1, which collapses neuronal growth cones. To investigate the mechanism of CRMP action, we screened mouse and human fetal cDNA libraries by the yeast two-hybrid method with CRMP as bait. Clones encoding CRMP1 and CRMP4 were isolated, suggesting that the CRMPs form multimers. This finding was confirmed by expressing various rat CRMP cDNAs in the yeast two-hybrid system. Rat CRMP isoforms show differential association with one another. Heterooligomerization is preferred in both two-hybrid and in vitro binding assays. Purified bovine brain CRMP migrates as a tetramer during size exclusion chromatography. Examination of binding with truncated forms of CRMPs indicates that the avid association of CRMPs requires nearly intact proteins. Through the analysis of CRMP chimeras, CRMP amino acids 8–134 and 281–435 are found to be essential for CRMP oligomerization. The tetrameric structure of CRMP resembles that of liver dihydropyrimidinase (DHPase), a protein that shares sequence similarity with the CRMPs. Although purified brain CRMP does not hydrolyze several DHPase substrates, it is likely that a related activity accounts for CRMP participation in neuronal growth cone signaling.
