Characterization of the Cubamyces Menziesii Terpenome

ChemBioChem, EarlyView.
The genome of Cubamyces menziesii reveals 18 putative sesquiterpene cyclase genes. These genes are cloned and expressed in Escherichia coli, yielding 10 active enzymes. Using farnesyl diphosphate as substrate, the enzymes are analyzed, and the products characterized after bioconversion, uncovering diverse sesquiterpene structures. This study highlights

Pavo: Discovery of a Star-forming Dwarf Galaxy Just Outside the Local Group

The Astrophysical Journal Letters, 2023
We report the discovery of Pavo, a faint ( M _V = −10.0), star-forming, irregular, and extremely isolated dwarf galaxy at D ≈ 2 Mpc. Pavo was identified in Dark Energy Camera Legacy Survey imaging via a novel approach that combines low surface brightness

The galaxy of Coxeter groups

Journal of Algebra
In this paper we introduce the galaxy of Coxeter groups -- an infinite dimensional, locally finite, ranked simplicial complex which captures isomorphisms between Coxeter systems. In doing so, we would like to suggest a new framework to study the isomorphism problem for Coxeter groups.

Properties of intra-group stars and galaxies in galaxy groups: ‘normal’ versus ‘fossil’ groups [PDF]

Monthly Notices of the Royal Astronomical Society, 2006
Cosmological LCDM simulations of 12 M_vir~10^14 Msun galaxy groups have been performed, invoking star formation, chemical evolution with non-instantaneous recycling, metallicity dependent radiative cooling, strong star-burst driven galactic super-winds and effects of a meta-galactic UV field. At z=0, intra-group light (IGL) fractions are found to be 12-

The properties of fossil groups of galaxies [PDF]

Astronomische Nachrichten, 2009
AbstractNumerical simulations as well as optical and X‐ray observations over the last few years have shown that poor groups of galaxies can evolve to what is called a fossil group. Dynamical friction as the driving process leads to the coalescence of individual galaxies in ordinary poor groups leaving behind nothing more than a central, massive ...

C13‐Deacylase from Nocardioides albus Resp. Streptomyces sp., Catalyzing Side Chain Hydrolysis on the Taxane Core

ChemCatChem, EarlyView.
An enzyme that has been identified and characterized as capable of hydrolyzing paclitaxel (Taxol), a key anticancer drug derived from Pacific yew (Taxus brevifolia) has been identified. Molecular docking (MD) simulations map the catalytic triad and critical residues that drive substrate‐enzyme interactions. The findings indicate the catalytic potential

Formation of the Dark Matter–Deficient S0 Galaxy NGC 4111 under the Tidal Interactions

The Astrophysical Journal Letters
We present high-sensitivity and large-scale atomic hydrogen (H i ) observations toward lenticular (S0) galaxy NGC 4111 using the Five-hundred-meter Aperture Spherical Radio Telescope.

LGBTQ+ Affirmative Care Training in Counselor Education: A Community‐Based Inquiry

Counselor Education and Supervision, EarlyView.
ABSTRACT Counselor educators, counselors‐in‐training, and LGBTQ+ community members engaged in a community‐based qualitative inquiry exploring LGBTQ+ affirmative care education. Findings revealed counselor educators’ components and delivery of content, developmental implications for applying LGBTQ+ affirmative care, and gaps between education and LGBTQ+

Human flaws and logical tools in engineering

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This paper explores the limitations of human cognition, especially in engineering research, emphasizing the need for mathematical models and methods to guide decision‐making and theory validation. While human cognition excels in certain tasks, it is prone to biases that can distort our understanding.
