Prediction Methods in Solar Sunspots Cycles [PDF]

Scientific Reports, 2016
AbstractAn understanding of the Ohl’s Precursor Method, which is used to predict the upcoming sunspots activity, is presented by employing a simplified movable divided-blocks diagram. Using a new approach, the total number of sunspots in a solar cycle and the maximum averaged monthly sunspots number Rz(max) are both shown to be statistically related to

Geopolitical Risk and Domestic Bank Deposits

Financial Management, EarlyView.
ABSTRACT We investigate the relationship between global geopolitical risk and bank deposit flows across a wide panel of European countries. Motivated by the pivotal role of deposit stability for financial intermediation and systemic resilience, we explore whether geopolitical shocks alter depositors’ portfolio choices.

The Legacy of Policy Inaction in Climate‐Growth Models

International Economic Review, EarlyView.
ABSTRACT To better understand the structure and core mechanisms of a broad class of climate‐growth models, we study a simplified version of the dynamic integrated model of climate and the economy (DICE) through the lens of growth theory. We analytically show that this model features a continuum of saddle‐point stable steady states.

Sunspot Cycle 24 and the Advent of Dalton-Like Minimum

, 2012
Ahluwalia and Jackiewicz (2011) have predicted that sunspot cycle 24 will be only half as active as cycle 23, reaching its peak in May 2013±6 months.

Ryugu Reference Project: Recommendations from the Measurement Definition Team

Meteoritics &Planetary Science, EarlyView.
Abstract Sample return missions play a significant role in planetary science by providing pristine extraterrestrial materials. JAXA's Hayabusa2 and NASA's OSIRIS‐REx missions have returned samples from the C‐type asteroids Ryugu and Bennu, respectively. The chemical and mineralogical compositions of these samples closely resemble those of CI chondrites,

The solar magnetic field since 1700: II. Physical reconstruction of total, polar and open flux

, 2011
We have used semi-synthetic records of emerging sunspot groups based on sunspot number data as input for a surface flux transport model to reconstruct the evolution of the large-scale solar magnetic field and the open heliospheric flux from the year 1700

Long‐term stability of transcrestal sinus augmentation

Periodontology 2000, EarlyView.
Abstract Transcrestal sinus augmentation has emerged as a minimally invasive alternative to lateral window techniques for vertical bone augmentation in the edentulous maxilla. Since its early introduction and modification over the last several decades, this technique has demonstrated predictable outcomes for implant placement in regions with limited ...

Latitude Distribution of Sunspots: Analysis Using Sunspot Data and A Dynamo Model

, 2017
In this paper, we explore the evolution of sunspot latitude distribution and explore its relations with the cycle strength. With the progress of the solar cycle, the distributions in two hemispheres from mid-latitudes propagate toward the equator and ...

Modulation of the sunspot cycle [PDF]

Astronomy & Geophysics, 2010
Solar activity has been abnormally high for the last half-century, but the extremely feeble start of the latest 11-year cycle suggests that this episode is probably coming to an end. This prospect raises some fascinating and important issues, involving an extremely wide range of timescales, writes Nigel Weiss.

Teacher Perspectives of Student Engagement in Data Practice Instruction: Two Classroom Conditions

School Science and Mathematics, EarlyView.
ABSTRACT This study examines high school science teachers' perceptions of student engagement in data practices across two instructional contexts: a scaffolded, student‐centered environment using the Science Practices Innovation Notebook (SPIN) and a business‐as‐usual (BAU) teacher‐led investigation.
