A Model-independent Radio Telescope Dark Matter Search in the L and S Bands

The Astrophysical Journal Letters
Ultralight bosonic dark matter in its most general form can be detected through its decay or annihilation to a quasimonochromatic radio line. Assuming only that this line is consistent with the most general properties of the expected phase space of our ...

Poseidon's Sanctuary at Samikon—The Discovery of an Ancient Temple Through an Integrated Geophysical and Geoarchaeological Survey Approach for Lagoonal and Swampy Environments

Archaeological Prospection, EarlyView.
ABSTRACT Below the classical fortress of Samikon at the coast of the western Peloponnese, ancient writer Strabo mentioned a sanctuary of Poseidon which served as the centre of the religious association of the Triphylian cities. In this paper, we describe the discovery and investigation of a building structure by means of geophysical and ...

Feasibility Study for Application of Digitized Henize Mt. Wilson Michigan Southern Sky Hα$$ \boldsymbol{\alpha} $$ Survey Low‐Dispersive Spectral Plates for Searches for Anomalous and Highly Redshifted Objects

Astronomische Nachrichten, EarlyView.
ABSTRACT The goal of this study is to confirm the feasibility of the use of digitized low dispersive MtWilson Michigan Southern Sky Hα$$ \alpha $$ survey astronomical photographic plates for modern astrophysical research. The detection of highly redshifted objects, such as early galaxies and quasars, is fundamental to understanding the universe's ...

Theranostic nanoplatform for high‐performance dual‐modal magnetic resonance imaging‐guided therapy of orthotopic hepatocellular carcinoma

BMEMat, EarlyView.
This article introduces a biomimetic Mn‐doped polydopamine nanoplatform (HAMM NPs) coated with cancer cell membranes. It enables targeted hepatocellular carcinoma theranostics via T1/T2 dual‐mode magnetic resonance imaging and tumor microenvironment‐triggered sonodynamic therapy/chemodynamic therapy, achieving potent antitumor efficacy in subcutaneous ...

GD-1 and the Milky Way Starless Dark Matter Subhalos

The Astrophysical Journal
Measurements of the GD-1 star stream velocity distribution within ±3° of the centerline find a total line-of-sight velocity spread of 5–6 km s ^−1 in the-well measured ϕ _1  = [−30, 0] region.

Spouted bed drying parameters and adjuvant effects on polyphenol retention and antioxidant activity in mango peel powders

The Canadian Journal of Chemical Engineering, EarlyView.
Spouted bed drying of mango peels with colloidal SiO2 and corn starch produces a free‐flowing powder with reduced agglomeration, increased drying yield, and preserved antioxidant and polyphenol content. Abstract The production of polyphenol‐rich powders is a promising strategy for valorizing agro‐industrial byproducts. This study evaluated drying yield,

CardiLect: A combined cross‐species lectin histochemistry protocol for the automated analysis of cardiac remodelling

ESC Heart Failure, Volume 12, Issue 2, Page 1398-1415, April 2025.
Abstract Background Cardiac remodelling, a crucial aspect of heart failure, is commonly investigated in preclinical models by quantifying cardiomyocyte cross‐sectional area (CSA) and microvascular density (MVD) via histological methods, such as immunohistochemistry.

COZMIC. II. Cosmological Zoom-in Simulations with Fractional non-CDM Initial Conditions

The Astrophysical Journal
We present 24 cosmological dark matter (DM)-only zoom-in simulations of a Milky Way analog with initial conditions appropriate for scenarios where non-cold dark matter (NCDM) is a fraction of the total DM abundance (f-NCDM models) as the second ...
