Geochronology of the Whittlesey sedimentary succession, eastern England: The ‘Pompeii’ of the British late Middle Pleistocene to Holocene record

open access: yesJournal of Quaternary Science, EarlyView.
Abstract The sedimentary succession at Whittlesey preserves a unique British late Middle Pleistocene to Holocene record back to a time equivalent to at least marine oxygen isotope stage 8 (ca. 250 ka). This study builds on previously published sedimentology, geochronology and palaeoecology results to establish 20 sedimentary facies associations, with ...

Vegetable Oil‐Based Materials for Drug Delivery Systems and Wound Dressings

open access: yesMacromolecular Bioscience, EarlyView.
Renewable resources like vegetable oils are increasingly explored for biomaterial production in biomedical applications. Their monoglycerides and triglycerides inherently possess functions or can be chemically modified to introduce functional groups suitable for polymerization, yielding biomaterials with desirable properties such as flexibility ...

The Weak Core, Partition‐Based Universal Stability, and Their Risk Associations Through A Partial Order

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT We are concerned with the stability of a transferable‐utility cooperative (TU) game. First, the concept of core can be weakened so that the blocking of changes is limited to only those with multilateral backings. This principle of consensual blocking, as well as the traditional core‐defining one of unilateral blocking and one straddling in ...

Veronica paczoskiana is no more than a pine forest ecotype of V. spicata that evolved independently in forest‐steppes of Ukraine and the Altai region

open access: yesNordic Journal of Botany, EarlyView.
The Eurasian steppe area has been a dynamic vegetation biome during the Pleistocene with its repeated cycles of forest advances and retreats. Such a scenario allows the evolution of ecotypes at the ecotone with the potential for parallel evolution in different parts of the distribution area.

Exploration of the Phytochemical and Antidiabetic Properties of Teucrium polium: A Natural Asset for Type 2 Diabetes Management

open access: yesChemistryOpen, EarlyView.
Teucrium polium shows antidiabetic activity with its phytochemical composition and biological activities. The essential oil is rich in carvacrol, thymol, γ‐terpinene, and o‐cymene, while the aqueous and hydroethanolic extracts are characterized by poliumoside, verbascoside, isorhamnetin‐3‐O‐rutinoside, and apigenin‐7‐rutinoside. Antioxidant activity is

Computational Study on Potentially Active Antibacterial Compounds in Secondary Metabolites of Extremophilic Microorganisms

open access: yesChemistryOpen, EarlyView.
This study employed density functional theory (DFT) and conceptual DFT (CDFT) to calculate the structures and properties of potential antibacterial compounds derived from 16‐membered lactone ring‐containing secondary metabolites of extremophiles, as well as midecamycin.

Urban wild meat and pangolin consumption across southern forested Cameroon: The limited influence of COVID‐19

open access: yesPeople and Nature, EarlyView.
Abstract Overexploitation of wildlife is pervasive in many tropical regions, and in addition to being a significant conservation and sustainability concern, it has received global attention given discussions over the origins of zoonotic disease outbreaks.

Recyclability of Polystyrene Bead Foams: Degradation Behavior over 10 Extrusion Cycles

open access: yesPolymer Engineering &Science, EarlyView.
This study investigates the multi‐cycle recycling of expanded polystyrene bead foam blended with virgin material. Material degradation is monitored by MFI, GPC, and mechanical testing. The results demonstrate that long‐term recyclability is feasible without progressive property loss, and that secondary high‐shear steps such as extrusion and pelletizing

Why Do They Do What They Do? A Model That Describes and Connects the Drivers of Learning Assistant Facilitation Practices

open access: yesScience Education, EarlyView.
ABSTRACT Learning assistants (LAs) help implement evidence‐based teaching in undergraduate active‐learning courses and support student learning through their facilitation. Here, we present a drivers‐of‐LA‐action model with empirical evidence that connects across the macro level of LA‐supported course design and the micro level of LA‐student ...
