Betaine‐Conjugated ß‐Peptide Foldamers: Influence of Quaternary Charge on Self‐Organization and MorphologyFormation

open access: yesChemistryOpen, EarlyView.
N‐terminal betaine conjugation modifies β‐peptide helices, influencing folding and self‐organization. For [1S, 2S]‐ACPC, folding to an H12 helix was unaffected, while [1R, 2R]‐ACHC formed an H14 helix instead of H10. Alternating heterochiral oligomers made of enantiomeric pairs of trans‐ACPC showed enhanced solubility and E‐strand formation.

Rotation curves velocities obtained by warm low-density plasma simulating dark halos and “dark matter”

open access: yesAIP Advances
The free electron model with Boltzmann statistics for spherical low-density plasmas is developed further, with asymptotic relations obtaining the density of electrons, mass densities, and the potentials of such plasmas.

Prioritized Real‐Time UAV‐Based Vessel Detection for Efficient Maritime Search

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Real‐time vessel detection in maritime environments is crucial for diverse applications requiring speed and accuracy. Static camera views often introduce blind spots, compromising detection efficiency. This paper proposes a novel, real‐time UAV‐based system that uses a dynamic camera control strategy to address this limitation.

Exploration of Halo Substructures in Integrals-of-motion Space with Gaia Data Release 3

open access: yesThe Astrophysical Journal
Using kinematic data from the Gaia Data Release 3 catalog, along with metallicity estimates robustly derived from Gaia BP/RP spectra, we have explored the Galactic stellar halo in search of both known and potentially new substructures.

Innovation for Sustainable Development: Assessing Sustainability‐Oriented Innovations in the UK Palm Oil Supply Chains

open access: yesSustainable Development, EarlyView.
ABSTRACT This research evaluates the adoption of Sustainability‐Oriented Innovations (SOIs) by UK food manufacturers, particularly in the palm oil sector. Despite the global palm oil industry's environmental and social impacts, such as deforestation and labour exploitation, empirical studies on SOIs are limited. This paper addressed this gap by mapping

The AGORA High-resolution Galaxy Simulations Comparison Project. V. Satellite Galaxy Populations in a Cosmological Zoom-in Simulation of a Milky Way–Mass Halo

open access: yesThe Astrophysical Journal
We analyze and compare the satellite halo populations at z ∼ 2 in the high-resolution cosmological zoom-in simulations of a 10 ^12 M _⊙ target halo ( z = 0 mass) carried out on eight widely used astrophysical simulation codes ( Art-I , Enzo , Ramses ...

High‐Contrast Colorless‐to‐Colored Thermochromic Materials

open access: yesSmall, EarlyView.
We developed new three‐component thermochromic systems showing reversible colorless‐to‐colored transition. Our general empirical rule applies to diverse fatty acid phase change materials and leuco dyes, enabling easily tunable transition temperature and activated colors (blue, cyan, green, pink, grey). Solid particles of these materials were integrated

The Stellar Bar–Dark Matter Halo Connection in the TNG50 Simulations

open access: yesThe Astrophysical Journal
Stellar bars in disk galaxies grow as stars in near-circular orbits lose angular momentum to their environments, including their dark matter (DM) halo, and transform into elongated bar orbits.
