Sedimentology, Volume 70, Issue 6, Page 1915-1944, October 2023., 2023 Abstract To interpret microbially influenced paleoenvironments in the sedimentary record, it is crucial to understand what processes control the development of microbial mats in modern environments. This article reports results from a multiyear study of Little Ambergris Cay, Turks and Caicos Islands, an uninhabited island floored by broad tracts of ...

Archaeometry, Volume 65, Issue 4, Page 862-880, August 2023., 2023 Abstract The location of Ghazali monastery away from the Nile valley within the relatively isolated environs of the Bayuda desert presents a landscape suggestive of mobility toward the monastery by those who chose to reside there as monks. To assess this potentiality, a sample of 37 individuals from the monastic cemetery (Cemetery 2) were analysed for ...

A Hox Transcription Factor Collective Binds a Highly Conserved Distal-less cis-Regulatory Module to Generate Robust Transcriptional Outcomes. [PDF]
PLoS Genetics, 2016 cis-regulatory modules (CRMs) generate precise expression patterns by integrating numerous transcription factors (TFs). Surprisingly, CRMs that control essential gene patterns can differ greatly in conservation, suggesting distinct constraints on TF ...

A review of microbial‐environmental interactions recorded in Proterozoic carbonate‐hosted chert
Geobiology, Volume 21, Issue 1, Page 3-27, January 2023., 2023 Abstract The record of life during the Proterozoic is preserved by several different lithologies, but two in particular are linked both spatially and temporally: chert and carbonate. These lithologies capture a snapshot of dominantly peritidal environments during the Proterozoic. Early diagenetic chert preserves some of the most exceptional Proterozoic

Geophysical Research Letters, Volume 49, Issue 24, 28 December 2022., 2022 Abstract The widespread development of Permian/Triassic boundary microbialites is a key biosedimentary response to the mass extinction event. The microbial communities that precipitated these structures remain, however, poorly resolved. Here, we report abundant columnar microfossils from five Permian‐Triassic successions in South China.

The Depositional Record, Volume 8, Issue 2, Page 786-828, June 2022., 2022 For the first time, the biogeomorphic response to the passage of a Severe Tropical Cyclone (TC Olwyn) is described from Hamelin Pool, Shark Bay, Western Australia. Hydrodynamic, sedimentological and biological processes and their products are described in the short to medium term (15 months) following the storm.

Water Resources Research, Volume 58, Issue 6, June 2022., 2022 Abstract What elements should a parsimonious model reproduce at a single scale to precisely simulate rainfall at many scales? We posit these elements are: (a) the probability of dry and linear correlation structure of the wet/dry sequence as a proxy reproducing the distribution of wet/dry spells, and (b) the marginal distribution of nonzero rainfall ...

On the impact of the jerk on structural dynamics
Proceedings in Applied Mathematics and Mechanics, Volume 21, Issue 1, December 2021., 2021 Abstract In mechanics, the term jerk, which is usually defined as the time derivative of acceleration, is often used incorrectly to interpret shock loads. Unfortunately, it is often very difficult to convince technicians with less insight into the basic laws of mechanics that their views are invalid, since jerky motions undoubtedly have certain effects

Advancing Space‐Time Simulation of Random Fields: From Storms to Cyclones and Beyond
Water Resources Research, Volume 57, Issue 8, August 2021., 2021 Abstract Realistic stochastic simulation of hydro‐environmental fluxes in space and time, such as rainfall, is challenging yet of paramount importance to inform environmental risk analysis and decision making under uncertainty. Here, we advance random fields simulation by introducing the concepts of general velocity fields and general anisotropy ...

Maximal Correlation Regression
IEEE Access, 2020 In this paper, we propose a novel regression analysis approach, called maximal correlation regression, by exploiting the ideas from the Hirschfeld-Gebelein-Rényi (HGR) maximal correlation. We show that in supervised learning problems, the optimal
