In this report, we are interested in the fast retrieval, in a large collection of points in highdimensional space, of points close to a query point: we want to efficiently find the set of points within a sphere of center query point pi and radius ǫ (a sphere query). It has been argued that beyond a rather small dimension (d ≥ 10) for such sphere queries as well as for other similarity queries, ...

This paper provides an α-order fractional Brownian motion (α-fBm) with Hurst index H ∈ (0,1) and (hereafter $Z_{H}^{\alpha } (t),~t\geq 0$ ), as extension of the n th fBm where is a nonnegative integer (n − 1,n) (e.g. Perrin et al. IEEE Trans. Signal Process., 49, 1049–1059, 2001). We show that process (t)$ (H + α)-self-similar satisfies long-range dependence property. The covariance function s...

Abstract Aim The aim of the study was to assess outcomes after a proximal femoral replacement (PFR). More PFRs are being performed in accordance with British Orthopaedic Oncology Society (BOOS) best practice guidance 2016. population studied patients metastatic disease actual or impending fractures. intervention and comparator were PFR intra-medullary nailing (IMN) respectively. primary outcome...

The paper presents an effective algorithm for absolute phase (not simply modulo-2π) estimation from incomplete, noisy, and modulo-2π observations in interferometric aperture radar and sonar (InSAR/InSAS). The adopted framework is also representative of other applications such as optical interferometry, magnetic resonance imaging, and diffraction tomography. The Bayesian viewpoint is adopted; th...

Pitting corrosion is a complex mechanism and has been found in the inner sections of offshore wind structures where standards at time indicated that those were water tight therefore free from corrosion. Pits propagate grow size this can have serious implications for structural integrity structure by reducing fatigue life but also under some conditions changing to crack whereby damage be acceler...

Meteoritical Bulletin 110 contains the 2802 meteorites approved by Nomenclature Committee of Society in 2021. It includes 10 falls (Arpu Kuilpu, Djadjarm, Glendale, Kindberg, Madura Cave, Motopi Pan, Orconuma, Punggur, Tihigrin, Winchcombe), with 2014 ordinary chondrites (including 1 ungrouped chondrite), 220 carbonaceous 11 ungrouped), 212 HED achondrites, 69 lunar meteorites, 62 ureilites, 43...

We report an octave-spanning coherent supercontinuum (SC) fiber laser with excellent noise and polarization properties. This was achieved by pumping a highly birefringent all-normal dispersion photonic crystal compact high-power ytterbium femtosecond at 1049 nm. system generates ultra-flat SC spectrum from 670 to 1390 nm power spectral density higher than 0.4 mW/nm extinction ratio of 17 dB acr...
