Constraining the Systematics of (Acoustic) Wave Heating Estimates in the Solar Chromosphere

open access: yesThe Astrophysical Journal, 2023
Acoustic wave heating is believed to contribute significantly to the missing energy input required to maintain the solar chromosphere in its observed state.

First Observations of a Geomagnetic Superstorm With a Sub‐L1 Monitor

open access: yesSpace Weather, Volume 23, Issue 3, March 2025.
Abstract Forecasting the geomagnetic effects of solar coronal mass ejections (CMEs) is currently an unsolved problem. CMEs, responsible for the largest values of the north‐south component of the interplanetary magnetic field, are the key driver of intense and extreme geomagnetic activity.

Decent Estimate of CME Arrival Time From a Data‐Assimilated Ensemble in the Alfvén Wave Solar Atmosphere Model (DECADE‐AWSoM)

open access: yesSpace Weather, Volume 23, Issue 1, January 2025.
Abstract Forecasting the arrival time of Earth‐directed coronal mass ejections (CMEs) via physics‐based simulations is an essential but challenging task in space weather research due to the complexity of the underlying physics and limited remote and in situ observations of these events. Data assimilation techniques can assist in constraining free model

Plant‐Based Biosynthesis of Metal and Metal Oxide Nanoparticles: An Update on Antimicrobial and Anticancer Activity

open access: yesChemBioEng Reviews, Volume 11, Issue 6, December 2024.
When it comes to finding novel ways to battle newly developing pathogenic strains and illnesses, nanoparticles are the first line of defense. Plant‐based nanoparticles are showing more significance over chemically or physically synthesized nanoparticles. Several plant species and their constituent parts have found several applications in medicine. They

Novel peptides with calcium‐binding capacity from antler bone hydrolysate, its bioactivity on MC3T3‐E1 cells, and the possible chelating mode

open access: yesFood Science &Nutrition, Volume 12, Issue 11, Page 9069-9084, November 2024.
This study identified that antler bone peptide‐calcium chelate promotes MC3T3‐E1 cell differentiation and mineralization. Two novel calcium‐chelating peptides were identified from antler bone hydrolysate with high chelation rates. Oxygen and nitrogen in the peptides' carboxyl and amino groups are involved in calcium binding, with a preference for ...

MEMPSEP‐III. A Machine Learning‐Oriented Multivariate Data Set for Forecasting the Occurrence and Properties of Solar Energetic Particle Events Using a Multivariate Ensemble Approach

open access: yesSpace Weather, Volume 22, Issue 9, September 2024.
Abstract We introduce a new multivariate data set that utilizes multiple spacecraft collecting in‐situ and remote sensing heliospheric measurements shown to be linked to physical processes responsible for generating solar energetic particles (SEPs). Using the Geostationary Operational Environmental Satellites (GOES) flare event list from Solar Cycle ...

Local Empirical Modeling of NmF2 Using Ionosonde Observations and the FISM2 Solar EUV Model

open access: yesJournal of Geophysical Research: Space Physics, Volume 129, Issue 9, September 2024.
Abstract Local empirical models of the F2 layer peak electron density (NmF2) are developed for 43 low‐ middle latitude ionosonde stations using auto‐scaled data from Lowell GIRO data center and manually scaled data from World Data Center for Ionosphere and Space Weather. Data coverage at these stations ranges from a few years to up to 6 decades.

Transition of the Sun to a Regime of High Activity: Implications for the Earth Climate and Role of Atmospheric Chemistry

open access: yesJournal of Geophysical Research: Atmospheres, Volume 129, Issue 15, 16 August 2024.
Abstract It was recently suggested that the Sun could switch to a high‐activity regime which would lead to a rise of ultraviolet radiation with an amplitude of about four times larger than the amplitude of an average solar activity cycle and a simultaneous drop in total solar irradiance.
