Journal of Geophysical Research: Space Physics, 2019 The period of 6–11 September 2017 was an active period in which multiple solar flares and a major geomagnetic storm occurred. The two largest flares, an X9.3 and an X8.2, were a disk flare and a limb flare, respectively.

Quasi-periodic Pulsations of Gamma-Ray Emissions from a Solar Flare on 2017 September 6 [PDF]
Astrophysical Journal, 2019 We investigate quasi-periodic pulsations (QPPs) of high-energy nonthermal emissions from an X9.3 flare (SOL2017-Sep-06T11:53), the most powerful flare since the beginning of solar cycle 24.

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab
Symbolic Interaction, EarlyView.How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Temporal Variation of Flare Occurrence Rates via the Spot Evolution on the Sun and Solar-type Stars
The Astrophysical JournalThe spot evolution on the Sun and solar-type stars is important for understanding the nature of consequential flaring activity. This study statistically investigates the variance of flare occurrence rate through the time evolution of spots on the Sun and

Evolution of coronal magnetic field parameters during X5.4 solar flare
Frontiers in Astronomy and Space Sciences, 2023 The coronal magnetic field over NOAA Active Region 11,429 during a X5.4 solar flare on 7 March 2012 is modeled using optimization based Non-Linear Force-Free Field extrapolation. Specifically, 3D magnetic fields were modeled for 11 timesteps using the 12-

The Journal of Dermatology, EarlyView.ABSTRACT Chronic spontaneous urticaria (CSU) affects 0.5%–1.0% of the population worldwide. However, information on the prevalence, comorbidities, and treatment patterns of CSU in Japan is limited. This observational study consisted of a cross‐sectional and longitudinal part.

Environmental disclosures and ESG fund ownership
Contemporary Accounting Research, EarlyView.Abstract In this study, we examine whether environmental, social, and governance (ESG) funds' investment decisions are sensitive to the existence and extent of firms' voluntary environmental disclosures. We create our measures of voluntary environmental disclosure using bigrams extracted from the Global Reporting Initiative standards. We provide robust

Antimicrobial prescribing guidelines for horses in Australia
Australian Veterinary Journal, EarlyView.The growing problem of antimicrobial resistance also affects equine veterinarians with increasing frequency. Antimicrobial stewardship and responsible prescribing are essential for a future in which effective antimicrobials are available, as it is unlikely that new antimicrobials will become available for use in horses.

Solar Flare Prediction with the Hybrid Deep Convolutional Neural Network
Astrophysical Journal, 2019 We propose a hybrid Convolutional Neural Network (CNN) model (Model 2) and modify a popular CNN model (Model 1) to predict multiclass solar flare occurrence within 24 hr.
