Short Wavelength Limit of the Dynamic Matsubara Local Field Correction

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT We investigate the short wavelength limit of the dynamic Matsubara local field correction G˜q,zl$$ \tilde{G}\left(\mathbf{q},{z}_l\right) $$ of the uniform electron gas based on direct ab initio path integral Monte Carlo (PIMC) results over an unprecedented range of wavenumbers, q≲20qF$$ q\lesssim 20{q}_{\mathrm{F}} $$, where qF$$ {q}_{\mathrm{

Mesoproterozoic surface oxygenation accompanied major sedimentary manganese deposition at 1.4 and 1.1 Ga

open access: yesGeobiology, Volume 21, Issue 1, Page 28-43, January 2023., 2023
Abstract Manganese (Mn) oxidation in marine environments requires oxygen (O2) or other reactive oxygen species in the water column, and widespread Mn oxide deposition in ancient sedimentary rocks has long been used as a proxy for oxidation. The oxygenation of Earth's atmosphere and oceans across the Archean‐Proterozoic boundary are associated with ...

Female and male Leach's Storm Petrels (Hydrobates leucorhous) pursue different foraging strategies during the incubation period

open access: yesIbis, Volume 165, Issue 1, Page 161-178, January 2023., 2023
Reproduction in procellariiform birds is characterized by a single egg clutch, slow development, a long breeding season and obligate biparental care. Female Leach's Storm Petrels Hydrobates leucorhous, nearly monomorphic members of this order, produce eggs that are between 20 and 25% of adult bodyweight.

The tentacles of surveillance: Cephalopods and United States satellite intelligence

open access: yesJournal for the Anthropology of North America, EarlyView.
Abstract This article examines the symbol placed on a US spy satellite, National Reconnaissance Office Launch–39 (NROL‐39). In 2013, NROL‐39 was launched into space, the payload vehicle and mission patch emblazoned with a gigantic octopus, its tentacles surrounding the globe, and the words “Nothing Is Beyond Our Reach” written below the globe.

What acoustic telemetry can and cannot tell us about fish biology

open access: yesJournal of Fish Biology, EarlyView., 2023
Abstract Acoustic telemetry (AT) has become ubiquitous in aquatic monitoring and fish biology, conservation, and management. Since the early use of active ultrasonic tracking that required researchers to follow at a distance their species of interest, the field has diversified considerably, with exciting advances in both hydrophone and transmitter ...

Additive manufacturing of a polyamide 12 and silica nanocomposite: A route for the reusability of a thermoplastic selective laser sintering powder

open access: yesPolymer Composites, EarlyView.
Additive Manufacturing of a polyamide 12 and silica nanocomposite: A route for the reusability of a thermoplastic selective laser intering powder. Abstract A route for the synthesis and additive manufacturing of a polymer‐silica nanocomposite with polyamide 12 (PA12) polymer as the matrix material and silica nanoparticles as the reinforcing filler, has

Formation of Ultra-short-period Planets in Hot Jupiter Systems: Application to WASP-47

open access: yesThe Astrophysical Journal Letters
The WASP-47 system is notable as the first known system hosting both inner and outer low-mass planetary companions around a hot Jupiter, with an ultra-short-period (USP) planet as the innermost planetary companion.

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
