An investigation of the current distribution in a 3-phase triaxial superconducting cable was conducted to study the phase imbalance under steady-state operation and to assist in the construction of a transient model to study operational impacts in a power grid. The triaxial cable consisted of three superconducting concentric phases inside a copper shield, with each phase composed of multiple la...

We develop an algorithm for reconstructing the triaxial shapes of dark matter halos from the anisotropic spatial distributions of their substructures. First, we construct an analytic model for the anisotropic spatial distributions of dark halo substructures under the assumption that the tidal field with non-zero trace in the triaxial mass distribution of the host halos generate the substructure...

We have recently developed a simple algorithm for the classification of household and locomotive activities using the ratio of unfiltered to filtered synthetic acceleration (gravity-removal physical activity classification algorithm, GRPACA) measured by a triaxial accelerometer. The purpose of the present study was to develop a new model for the immediate estimation of daily physical activity i...

Heart rate telemetry is frequently used to estimate daily activity in children and to validate other methods. This study compared the accuracy of heart rate monitoring, pedometry, triaxial accelerometry, and uniaxial accelerometry for estimating oxygen consumption during typical children's activities. Thirty Welsh children (mean age 9.2 +/- 0.8 yr) walked (4 and 6 km/h) and ran (8 and 10 km/h) ...

Statistics of lensed arcs in clusters of galaxies serve as a powerful probe of both the non-sphericity and the inner slope of dark matter halos. We develop a semi-analytic method to compute the number of arcs in triaxial dark matter halos. This combines the lensing cross section from the Monte Carlo ray-tracing simulations, and the probability distribution function (PDF) of the axis ratios eval...

Taking the standard size coal block samples defined by ISRM as research objects, both properties of methane diffusion of coal block under triaxial compressive stress and characteristic influences caused by methane pressure were systematically studied with thermo-fluid-solid coupling with triaxial servocontrolled seepage equipment of methane-containing coal. The result shows the methane diffusio...

We present a detailed non-spherical modeling of dark matter halos on the basis of a combined analysis of the high-resolution halo simulations (12 halos with N ∼ 10 particles within their virial radius) and the large cosmological simulations (5 realizations with N = 512 particles in a 100hMpc boxsize). The density profiles are well approximated by a sequence of the concentric triaxial distributi...

The consequences of nuclear black holes for the structure and dynamics of stellar spheroids are reviewed. Slow growth of a black hole in a pre-existing core produces a power-law cusp, ρ ∼ r −γ , with γ ≈ 2, similar to the steep cusps seen in faint elliptical galaxies. The weaker cusps in bright ellipticals, γ ∼ < 1, may result from ejection of stars by a coalescing black-hole binary; there is m...

One of the aims of Identification and Prevention of Dietary- and Lifestyle-Induced Health Effects in Children and Infants (IDEFICS) validation study is to validate field measures of physical activity (PA) and energy expenditure (EE) in young children. This study compared the validity of uniaxial accelerometry with heart-rate (HR) monitoring vs. triaxial accelerometry against doubly labeled wate...

Following the M7.0 strike-slip earthquake near Kumamoto, Japan, in April of 2016, most geotechnical engineering experts believed that there would be significant soil liquefaction and liquefaction-induced infrastructure damage observed densely populated city Kumamoto during post-event reconnaissance. This belief was driven by several factors including young geologic environment, alluvially depos...
