Impact of Giant Iceberg A68A on the Physical Conditions of the Surface South Atlantic, Derived Using Remote Sensing

Geophysical Research Letters, Volume 50, Issue 18, 28 September 2023., 2023
Abstract Giant icebergs release cold, fresh meltwater as they drift, perturbing the physical conditions of the surface ocean. This study uses satellite‐derived sea surface salinity and temperature measurements to explore the physical impact of supergiant iceberg A68A between September 2020 and June 2021.

Giant breast phyllodes tumor with silent thromboembolism: A case report

Cancer Reports, Volume 6, Issue 9, September 2023., 2023
Abstract Background Phyllodes tumor (PT) is a solid fibroepithelial breast lesion with proliferation of stromal and epithelial elements, usually presents with a rapidly expanding feature. Venous thromboembolism (VTE) have been reported to increase the burden in terms of mortality and morbidity of malignant tumor, and associate with worsened survival ...

First Observations With a GNSS Antenna to Radio Telescope Interferometer

Radio Science, Volume 58, Issue 8, August 2023., 2023
Abstract We describe the design of a radio interferometer composed of a Global Navigation Satellite Systems (GNSS) antenna and a Very Long Baseline Interferometry radio telescope. Our eventual goal is to use this interferometer for geodetic applications including local tie measurements.

Burial and Denudation Alter Microbial Life at the Bottom of the Hypo‐Critical Zone

Geochemistry, Geophysics, Geosystems, Volume 24, Issue 6, June 2023., 2023
Abstract How subsurface microbial life changed at the bottom of the kilometers‐deep (hypo) Critical Zone in response to evolving surface conditions over geologic time is an open question. This study investigates the burial and exhumation, biodegradation, and fluid circulation history of hydrocarbon reservoirs across the Colorado Plateau as a window ...

Characteristics and Consequences of Red Bed Bleaching by Hydrocarbon Migration: A Natural Example From the Entrada Sandstone, Southern Utah

Geochemistry, Geophysics, Geosystems, Volume 23, Issue 8, August 2022., 2022
Abstract Extensive regions of yellow and white (“bleached”) sandstones within the terrestrial Jurassic red bed deposits of the Colorado Plateau reflect widespread interaction with subsurface reduced fluids which resulted in the dissolution of iron‐oxide grain coatings.

Unravelling the pore network and its behaviour: An integrated NMR, MICP, XCT and petrographical study of continental spring carbonates from the Ballık area, SW Turkey

The Depositional Record, Volume 8, Issue 1, Page 292-316, February 2022., 2022
Applying an integrated methodology, including petrography, mercury injection capillary pressure (MICP), laboratory nuclear magnetic resonance (NMR) and X‐ray computed tomography (XCT), on continental spring carbonate reservoir analogue samples is a prerequisite to understanding plug scale porosity and permeability heterogeneities.

Controversial Issues of Hydrocarbon Field Formation and the Role of Geomagnetic Fields

International Journal of Geophysics, Volume 2022, Issue 1, 2022., 2022
This review paper presents controversial issues on the formation of hydrocarbon deposits. We look into the geological contradictions of the abiogenic and biogenic theories of petroleum origin, indicating the connection between hydrocarbon deposits and disjunctive dislocations, as well as present disputes about the geological period over which ...

Near-IR TRGB Distance to Nearby Dwarf Irregular Galaxy NGC 6822 [PDF]

Journal of Astronomy and Space Sciences, 2008
We report the distance modulus of nearby dwarf irregular galaxy NGC 6822 estimated from the so-called Tip of Red-giant Branch (TRGB) method. To detect the apparent magnitudes of the TRGB we use the color-magnitude diagrams (CMDs) and luminosity functions

Yellow Supergiants and Post-red Supergiant Evolution in the Large Magellanic Cloud

The Astronomical Journal, 2023
The empirical evidence for an upper-mass limit for the red supergiant (RSG) progenitors of the Type II-P SNe at about 18 MSun, raises questions about the fate of the most luminous, most massive RSGs.

Possible Detection of the Progenitor of the Type II Supernova SN 2023ixf

The Astrophysical Journal Letters, 2023
Stellar evolution theory predicts multiple pathways to the explosive deaths of stars as supernovae. Locating and characterizing the progenitors of well-studied supernovae is important to constrain the theory and to justify and design future surveys to ...
