Mid-Infrared Imaging of the Protostellar Binary L1448N--IRS3(A,B) [PDF]

open access: yes, 2002
Mid-infrared (10-25 \micron) imaging of the protostellar binary system L1448N-IRS3(A,B) is presented. Only one source, IRS3(A), was detected at mid-infrared wavelengths -- all of the mid-infrared emission from IRS3(A,B) emanates from IRS3(A).

A NEW METHOD FOR NORTH-SOUTH ASYMMETRY OF SUN SPOT AREA ANALYSIS [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2007
We have studied the temporal variation in the North-South asymmetry of the sunspot area during the period from 1874 to 2007. Though the 9-year periodicity is commonly reported, shorter periodicities is still under study.

Coronal seismology by slow waves in non-adiabatic conditions

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Slow magnetoacoustic waves represent an important tool for probing the solar coronal plasma. The majority of seismological methods with slow waves are based on a weakly non-adiabatic approach, which assumes the coronal energy transport has only weak ...

Is the Polar Region Different from the Quiet Region of the Sun?

open access: yes, 2010
Observations of the polar region of the Sun are critically important for understanding the solar dynamo and the acceleration of solar wind. We carried out precise magnetic observations on both the North polar region and the quiet Sun at the East limb ...

Solar ultraviolet protection provided by human head hair [PDF]

open access: yes, 2009
The solar erythemal UV irradiances through human hair and the protection from UV provided by human head hair have been investigated for a solar zenith angle (SZA) range of 17 to 51 degrees for the conditions of a head upright in full sun, a head upright ...

Exploring New Horizons for Wine Grapes: Modulating Functional Effects by Varying Harvest Timing and Solar Exposure

open access: yesFoods
Grenache (GN) and Cabernet Sauvignon (CS) are two traditional red grape varieties widely cultivated in the Mediterranean area and both late-ripening cultivars, which makes them less sensitive to global warming conditions and more stable to harvest timing.

Data mining for science of the sun-earth connection as a single system

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Establishing the Sun-Earth connection requires overcoming the challenges of exploring the data from past and current missions and leveraging tools and models (data mining) to create an efficient system treatment of the Sun and heliosphere. However, solar

High Energy Electron Signals from Dark Matter Annihilation in the Sun [PDF]

open access: yes, 2010
In this paper we discuss two mechanisms by which high energy electrons resulting from dark matter annihilations in or near the Sun can arrive at the Earth.

PICALM::MLLT10 translocated leukemia

open access: yesFEBS Letters, EarlyView.
This comprehensive review of PICALM::MLLT10 translocated acute leukemia provides an in‐depth review of the structure and function of CALM, AF10, and the fusion oncoprotein (1). The multifaceted molecular mechanisms of oncogenesis, including nucleocytoplasmic shuttling (2), epigenetic modifications (3), and disruption of endocytosis (4), are then ...

The Relative Position of the Solar Magnetic Dipole Axis and Rotation Axis of the Sun

open access: yesGalaxies
We estimated the relative location of the solar rotation axis and the magnetic axis of the solar dipole, which were defined as centers of polar coronal holes.
