Project VeSElkA: Search for vertical stratification of element abundances in HD157087
, 2018 The new spectropolarimetric spectra of HD157087 obtained recently with ESPaDOnS at CFHT are analysed to verify the nature of this object. The fundamental stellar parameters $T_{\rm eff}$ = 8882 K, $\log{g}$=3.57 have been obtained for HD157087 from the ...

Functional factor analysis for periodic remote sensing data [PDF]
, 2012 We present a new approach to factor rotation for functional data. This is achieved by rotating the functional principal components toward a predefined space of periodic functions designed to decompose the total variation into components that are nearly ...

Forward Period Analysis Method of the Periodic Hamiltonian System
PLOS ONE, 2016 Using the forward period analysis (FPA), we obtain the period of a Morse oscillator and mathematical pendulum system, with the accuracy of 100 significant digits. From these results, the long-term [0, 1060] (time unit) solutions, ranging from the Planck time to the age of the universe, are computed reliably and quickly with a parallel multiple ...

Lifestyle Behaviors and Cardiotoxic Treatment Risks in Adult Childhood Cancer Survivors
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Higher doses of anthracyclines and heart‐relevant radiotherapy increase cardiovascular disease (CVD) risk. This study assessed CVD and CVD risk factors among adult childhood cancer survivors (CCSs) across cardiotoxic treatment risk groups and examined associations between lifestyle behaviors and treatment risks.

Proteomic Analysis Reveals a New Benefit of Periodic Mechanical Stress on Chondrocytes
Cellular Physiology and Biochemistry, 2017 Background/Aims: In recent years, a variety of studies have been performed to investigate the cellular responses of periodic mechanical stress. In our previous studies, we found that periodic mechanical stress can promote proliferation and matrix ...

Fourier Analysis of Periodic Radon Transforms [PDF]
Journal of Fourier Analysis and Applications, 2020 AbstractWe study reconstruction of an unknown function from its d-plane Radon transform on the flat torus $${\mathbb {T}}^n = {\mathbb {R}}^n /{\mathbb {Z}}^n$$ T n = R n / Z n when $$1 \le d \le n-1$$ 1 ≤ d ≤ n - 1 . We prove new reconstruction formulas and stability results with respect to weighted Bessel potential norms.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.

Two-scale convergence analysis and numerical simulation for periodic Kirchhoff plates
HeliyonHomogenization analysis methods provide a high-efficiency tool to address periodic structures. However, the popular Asymptotic Homogenization Method (AHM) cannot be directly applied to the homogenization of periodic plate structures due to less ...

Periodicity in distribution. I. Discrete systems
International Journal of Mathematics and Mathematical Sciences, 2002 We consider the existence of periodic in distribution solutions to the difference equations in a Banach space. A random process is called periodic in distribution if all its finite-dimensional distributions are periodic with respect to shift of time with
