This article aims to alert the medical community and public health authorities to accumulating evidence on health benefits from sun exposure, which suggests that insufficient sun exposure is a significant public health problem....
Is the Sun a Magnet?
DO Gough
Jul 05, 2017
It has been argued (Gough and McIntyre in Nature394, 755, 1998) that the only way for the radiative interior of the Sun to be rotating uniformly in the face of the differentially rotating convection zone is for it to be pervaded...
Solar Radiation Prediction Model Based on Spatial Attention Mechanisms and Sun Position Feature Maps
This study introduces a novel method for predicting solar radiation by focusing on the sun's position and cloud conditions in the sky. The proposed approach utilizes sun position feature maps and spatial attention mechanisms to...

Unsigned Magnetic Flux as a Proxy for Radial-velocity Variations in Sun-like Stars
RD Haywood, TW Milbourne, SH Saar, A Mortier, D Phillips, D Charbonneau, AC Cameron, HM Cegla, N Meunier, MLP Iii
Aug 08, 2022
We estimate disc-averaged RV variations of the Sun over the last magnetic
cycle, from the single Fe I line observed by SDO/HMI, using a physical model
for rotationally modulated magnetic activity that was previously...
Outsourcing natural resource requirements within China.
Yaowen Zhang, Ling Shao, Xudong Sun, Mengyao Han, Xueli Zhao, Jing Meng, Bo Zhang, Han Qiao
Apr 12, 2019
Consumption demands are final drivers for the extraction and allocation of natural resources. This paper investigates demand-driven natural resource requirements and spatial outsourcing within China in 2012 by using the latest...

Analysis of a new design of the hybrid energy storage system used in the residential m-CHP systems
Jianwei Li, Xudong Wang, Zhenyu Zhang, Simon Le Blond, Qingqing Yang, Min Zhang, Weijia Yuan
Feb 01, 2017
The energy balancing problem is the main challenge for the effective application of micro combined heat and power (m-CHP) in a residential context. Due to its high energy density and relative robustness, the lead-acid battery...
A novel controller of a battery-supercapacitor hybrid energy storage system for domestic applications
Electrical energy storage is an attractive technology for complementing domestic scale Combined Heat and Power (CHP) because when CHP is dispatched to meet the heating load, the storage can reconcile any mismatch between the...
Effective Teaching for Place Value Understanding
A lesson sequence for place value was developed as an early intervention for kindergarteners. The sequence begins with a children’s picture book involving language familiar to children and continues with hands-on activities for...

Here comes the sun
Photosynthesis started to evolve some 3.5 billion years ago CO2 is the substrate for photosynthesis and in the past 200-250 years, atmospheric levels have approximately doubled due to human industrial activities. However, this...
