Redshift‐Agnostic Machine Learning Classification: Unveiling Peak Performance in Galaxy, Star, and Quasar Classification (Using SDSS DR17)

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT Classification of galaxies, stars, and quasars using spectral data is fundamental to astronomy, but often relies heavily on redshift. This study evaluates the performance of 10 machine learning algorithms on SDSS data to classify these objects, with a particular focus on scenarios where redshift information is unavailable.

Exploring Dark Photon Production and Kinetic Mixing Constraints in Heavy‐Ion Collisions

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT Vector U‐bosons, often referred to as “dark photons,” are potential candidates for mediating dark matter interactions. In this study, we outline a procedure to derive theoretical constraints on the upper bound of the kinetic mixing parameter ϵ2MU$$ {\upvarepsilon}^2\left({M}_U\right) $$ using dilepton data from heavy‐ion from SIS to RHIC ...

Dark Energy From the Gravitational Wave Background With Scalar Field Dark Matter

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT Recent observational results, such as those from pulsar timing arrays (PTA), suggest a low‐frequency Gravitational Wave Background (GWB) permeates our universe. This opens the possibility that gravitational waves could span a broader spectrum, potentially impacting cosmological scales.

Staphylococcus Aureus AgrA Modulators from South African Antimicrobial Plants.

open access: yesChemistry &Biodiversity, Accepted Article.
South African plants are an underutilized metabolites source for novel antimicrobials targeting key quorum sensing (QS) systems like the Staphylococcus aureus AgrA. AgrA modulating metabolites constitute a new approach to reducing resistance development.

Characterization of the Cubamyces menziesii terpenome

open access: yesChemBioChem, Accepted Article.
Long‐lasting polypore fungi are significant producers of terpene cyclases of high interest for medicinal or biotechnological applications. Following the 1,000 Fungal Genomes initiative launched by the Joint Genome Institute, we explored the genome of Cubamyces (C.) menziesii and identified eighteen genes encoding sesquiterpene cyclases. In a search for

Facilitating Reproducibility in Catalysis Research with Managed Workflows and RO‐Crates: A Galaxy Case Study

open access: yesChemCatChem, Accepted Article.
Publishing supporting data significantly impacts researchers' productivity, especially in experiments requiring extensive tracking of data, processing steps, parameters, and outputs. A managed workflow environment, combined with RO‐Crates, addresses these data management challenges. Workflows provide an alternative for handling complex data analyses by

A review of multiscale numerical modeling of rock mechanics and rock engineering

open access: yesDeep Underground Science and Engineering, EarlyView.
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

High‐Performance Stretchable Gallium Battery for Wearable Electronics, Through Synthesis of Foam Electrodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Foam electrode synthesis, characterization, and application as a cathode in batteries. The demand for sustainable and stretchable thin‐film printed batteries for bioelectronics, wearables, and e‐textiles is rapidly increasing. Recently, we developed a fully 3D‐printed soft‐matter thin‐film Ga‐Ag2O battery with 3R characteristics: resilient to ...

Facilitating learning in immersive virtual reality: Segmentation, summarizing, both or none?

open access: yesJournal of Computer Assisted Learning, Volume 39, Issue 1, Page 218-230, February 2023., 2023
Abstract Introduction This study investigates the effectiveness of the segmentation principle from the cognitive theory of multimedia learning as well as the effectiveness of the generative learning strategy of summarization in immersive virtual reality (IVR) within a sample of preadolescents.

Quality of life in heart failure. The heart of the matter. A scientific statement of the Heart Failure Association and the European Association of Preventive Cardiology of the European Society of Cardiology

open access: yesEuropean Journal of Heart Failure, EarlyView.
For most patients with chronic, progressive illnesses, maintaining good quality of life (QoL), with preserved functional capacity, is just as crucial as prolonging survival. Patients with heart failure (HF) experience much worse QoL and effort intolerance than both the general population and people with other chronic conditions, since they present a ...
