Subterranean environments contribute to three‐quarters of classified ecosystem services
Biological Reviews, EarlyView.ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

On the Effects of Parameters on Galaxy Properties in CAMELS and the Predictability of Ωm
The Astrophysical JournalRecent analyses of cosmological hydrodynamic simulations from CAMELS have shown that machine learning models can predict the parameter describing the total matter content of the universe, Ω _m , from the features of a single galaxy.

Statistical properties of galaxy distributions [PDF]
Nonlinear Processes in Geophysics, 1996 The recent availability of complete three dimensional samples of galaxies and clusters permits a direct study of their spatial properties. We present a brief review of galaxy correlations based on the methods modern statistical Physics.

Comparing Globular Cluster System Properties with Host Galaxy Environment
The Astrophysical Journal, 2023 We present Hubble Space Telescope photometry in the optical (F475X) and near-infrared (F110W) bands of the globular cluster (GC) systems of the inner halos of a sample of 15 massive elliptical galaxies.

Properties of Galaxies with Peculiar Nuclei [PDF]
Publications of the Astronomical Society of the Pacific, 1967 In a former note (Sersic and Pastoriza 1965) we published the results of a survey of bright southern galaxies which were inspected for peculiarities in their nuclei. Although the sample was small ( 35 galaxies) it suggested a relationship between the existence of a bar and the presence of abnormal features in their nuclei.

Chlorinated Paracyclophanes: Composition Analysis and Direct Metal‐Free Alkylation with n‐BuLi
European Journal of Organic Chemistry, EarlyView.A transition‐metal‐free alkylation of pseudo‐para dichloro[2.2]paracyclophane (Cl2‐PCP) is reported, utilizing the purified pseudo‐para isomer and n‐butyllithium (BuLi). Optimization with the chelating agent TMEDA and refluxing n‐heptane significantly boosted selectivity and reaction rate, providing the dialkylated product in 22% isolated yield.

Constraints on Assembly Bias from Galaxy Clustering
, 2016 We constrain the newly-introduced decorated Halo Occupation Distribution (HOD) model using SDSS DR7 measurements of projected galaxy clustering or r-band luminosity threshold samples.
