Reproduction of the Lyman α irradiance variability from analysis of full-disk images in the CaII K-line [PDF]

, 1995
We have compared three years of daily CaII K-line images from the Big Bear Solar Observatory (BBSO) with HI Lymanα irradiance data from the Upper Atmosphere Research Satellite (UARS).

Comparison between Laplace-Lagrange Secular Theory and Numerical Simulation

, 2018
The large increase in exoplanet discoveries in the last two decades showed a variety of systems whose stability is not clear. In this work we chose the $\upsilon$ Andromedae system as the basis of our studies in dynamical stability.

Risk Prediction Models for Recurrence After Curative Treatment of Early‐Stage or Locally Advanced Lung Cancer: A Systematic Review

Aging and Cancer, EarlyView.
This systematic review synthesizes prognostic models for survival and recurrence in resected non‐small cell lung cancer. While many models demonstrate moderate to good discrimination, few are externally validated and reporting quality is variable, limiting clinical applicability and highlighting the need for robust, transparent model development ...

Elements of a Theory of Religious-Secular Competition

Política & Sociedade, 2017
This article presents basic elements of a theory of religious-secular competition on the individual level. The theory claims that individuals in many societies may choose between religious and secular options, creating a situation of competition between

Bayesian inversion for the filtered flow at the Earth's Core Mantle Boundary

, 2013
The inverse problem which consists of determining the flow at the Earth's Core Mantle Boundary according to an outer core magnetic field and secular variation model, has been investigated through a Bayesian formalism. To circumvent the issue arising from

Tracking Motor Progression and Device‐Aided Therapy Eligibility in Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To characterise the progression of motor symptoms and identify eligibility for device‐aided therapies in Parkinson's disease, using both the 5‐2‐1 criteria and a refined clinical definition, while examining differences across genetic subgroups.

Geomagnetic secular variation since 1901 [PDF]

Deep Sea Research Part B. Oceanographic Literature Review, 1981
Summary. All available annual means, from the world-wide network of magnetic observatories, of north intensity (X), east intensity (Y) and vertical intensity (Z) from 1901 to 1977 are subjected to spherical harmonic analysis to obtain 38 models of the Earth's geomagnetic field at two-year intervals.

The influence of regularization on the geomagnetic core field modeling

地球与行星物理论评
Earth's magnetic field is generated through the dynamo action in the liquid outer core. Using observational data from geomagnetic satellites and observatories, we can construct geomagnetic models that describe spatial and temporal variations of the core ...

Secular variation of the geocenter [PDF]

Journal of Geophysical Research: Solid Earth, 2000
The degree 1 deformations of Earth induced by a surface load are computed, in a reference frame related to the center of mass of the planet, using a theoretical approach (Love number formalism), at secular timescale, where Earth has a viscoelastic behavior.

Lessons Learned From a Delayed‐Start Trial of Modafinil for Freezing of Gait in Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Freezing of gait (FOG) in people with Parkinson's disease (PwPD) is debilitating and has limited treatments. Modafinil modulates beta/gamma band activity in the pedunculopontine nucleus (PPN), like PPN deep brain stimulation. We therefore tested the hypothesis that Modafinil would improve FOG in PwPD.
