Комплекс программ моделирования геодинамо на основе спектральных эредитарных моделей

Vestnik KRAUNC: Fiziko-Matematičeskie Nauki
Исследование задачи геодинамо часто проводят на основе спектральных моделей, когда поля задачи полностью или частично раскладываются по собственным полям (модам) подходящих спектральных задач.

A spectral model for multimodal redshift estimation [PDF]

2016 IEEE Symposium Series on Computational Intelligence (SSCI), 2016
We present a physically inspired model for the problem of redshift estimation. Typically, redshift estimation has been treated as a regression problem that takes as input magnitudes and maps them to a single target redshift. In this work we acknowledge the fact that observed magnitudes may actually admit multiple plausible redshifts, i.e.

Running of the spectral index and inflationary dynamics of F(R) gravity

Physics Letters B, 2022
In this work we shall provide a model-independent general calculation of the running of the spectral index for vacuum F(R) gravities. We shall exploit the functional form of the spectral index and of the tensor-to-scalar ratio in order to present a ...

Spectral goodness of fit for network models [PDF]

Social Networks, 2014
We introduce a new statistic, 'spectral goodness of fit' (SGOF) to measure how well a network model explains the structure of an observed network. SGOF provides an absolute measure of fit, analogous to the standard R-squared in linear regression.

Многомасштабная модель геодинамо: сопряжение крупномасштабной и мелкомасштабной подмоделей

Vestnik KRAUNC: Fiziko-Matematičeskie Nauki
Формирование главного геомагнитного поля обеспечивается работой механизма гидромагнитного динамо — генерации магнитного поля движением проводящей среды. Динамо Земли (геодинамо) управляется конвекцией жидкого металла во внешнем ядре Земли.

Sensitivity experiments to mountain representations in spectral models

Annals of Geophysics, 2000
This paper describes a set of sensitivity experiments to several formulations of orography. Three sets are considered: a "Standard" orography consisting of an envelope orography produced originally for the ECMWF model, a"Navy" orography directly from the

A predictive model for the spectral “bioalbedo” of snow [PDF]

Journal of Geophysical Research: Earth Surface, 2017
AbstractWe present the first physical model for the spectral “bioalbedo” of snow, which predicts the spectral reflectance of snowpacks contaminated with variable concentrations of red snow algae with varying diameters and pigment concentrations and then estimates the effect of the algae on snowmelt.

Ovarian Sex Cord Stromal Tumors in Children and Adolescents—The European Standard Clinical Practice Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT As part of the European Cooperative Study Group for Paediatric Rare Tumours initiative, we developed standard clinical practice guidelines for ovarian sex cord stromal tumors, based on comprehensive national and international cohort analyses, literature review, and a final expert consensus conference.

База данных параметров базисных мод и коэффициентов cпектральных моделей геодинамо

Vestnik KRAUNC: Fiziko-Matematičeskie Nauki
Спектральные модели геодинамо строятся на основании конечного набора базисных стационарных полей (мод). Поля скорости, температуры и магнитной индукции представляются в моделях в виде линейных комбинаций базисных мод с коэффициентами (амплитудами ...

Acute Neurological Events in Children With Hemoglobin SC Disease: A Multicenter Retrospective Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Neurological manifestations in children with hemoglobin SC (HbSC) disease remain insufficiently characterized, particularly regarding acute events. The aim of this study was to describe the spectrum and frequency of acute neurological events in a multicenter cohort of children with HbSC disease.
