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...
Insufficient Sun Exposure Has Become a Real Public Health Problem.

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....
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

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...
The high-energy Sun - probing the origins of particle acceleration on our nearest star
Abstract As a frequent and energetic particle accelerator, our Sun provides us with an excellent astrophysical laboratory for understanding the fundamental process of particle acceleration. The...

Feature-Aware Pixel Art Animation
Pixel art is a modern digital art in which high resolution images are abstracted into low resolution pixelated outputs using concise outlines and reduced color palettes. Creating pixel art is a labor intensive and...
Scale-aware Black-and-White Abstraction of 3D Shapes
Flat design is a modern style of graphics design that minimizes the number of design attributes required to convey 3D shapes. This approach suits design contexts requiring simplicity and efficiency, such as mobile computing...
Fitting quadrics with a Bayesian prior
Quadrics are a compact mathematical formulation for a range of primitive surfaces. A problem arises when there are not enough data-points to compute the model but knowledge of the shape is available. This paper presents a method...
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...

Forward and Inverse D-Form Modelling based on Optimisation
D-Form is a special piece-wise developable surface formed by aligning the boundaries of two planar domains. It has been widely used in different design scenarios. In this paper, we study how to computationally and intuitively...

Ellipsoid Packing Structures on Freeform Surfaces
Designers always get good inspirations from fascinating geometric structures gifted by the nature. In the recent years, various computational design tools have been proposed to help generate cell packing structures on freeform...
Reforming Shapes for Material-aware Fabrication
As humans, we regularly associate shape of an object with its built material. In the context of geometric modeling, however, this inter-relation between form and material is rarely explored. In this work, we propose a novel...
Anisotropic Surface Remeshing without Obtuse Angles
We present a novel anisotropic surface remeshing method that can efficiently eliminate obtuse angles. Unlike previous work that can only suppress obtuse angles with expensive resampling and Lloyd-type iterations, our method...
Coarse-to-Fine
Facial structure editing of portrait images is challenging given the facial variety, the lack of ground-truth, the necessity of jointly adjusting color and shape, and the requirement of no visual artifacts. In this paper, we...

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...
