Holocene vegetation change and fire–plant diversity shifts in Mediterranean France

Journal of Quaternary Science, EarlyView.
ABSTRACT Changes in fire activity are recognized as a major threat to biodiversity and vegetation communities across the Mediterranean Basin. However, long‐term fire–vegetation interactions remain poorly investigated. Here, we combine a high‐resolution charcoal record with pollen data from the “Étang des Aulnes” lake (southern France) to reconstruct ...

Characterization and Preliminary Investigation of Alkylpolyglucoside Combined With a Biopolymer for Enhanced Oil Recovery

Journal of Surfactants and Detergents, EarlyView.
Materials and main results of the study. ABSTRACT Surfactant–polymer (SP) flooding is a promising Enhanced Oil Recovery (EOR) technique, combining improved displacement from surfactants with enhanced sweep efficiency from polymers. This study investigates two SP systems based on the biopolymer scleroxanthan (a blend of sclerotium gum and xanthan gum ...

Integrated morphological and physiological plasticity of root for improved seedling growth in Cunninghamia lanceolata and Schima superba under nitrogen deficiency and different NH4+-N to NO3−-N ratio

Frontiers in Plant Science
ContextRoot plasticity is an important physiological mechanism for trees to adapt to nitrogen (N) deficiency and the unequal distribution of ammonium nitrogen (NH4+-N) and nitrate nitrogen (NO3−-N) for promoting growth.

Gymnema sylvestre: Bioactive constituents, health benefits, and emerging applications in nutraceuticals and functional foods

JSFA reports, EarlyView.
Abstract Gymnema sylvestre (Retz.) R.Br. ex‐Schult., commonly known as “gurmar” or “sugar destroyer,” belongs to the Apocynaceae family and is traditionally used in Ayurveda for diabetes management. This review synthesizes ethnomedicinal evidence with contemporary pharmacological studies, to evaluate the therapeutic properties and mechanistic actions ...

Ultra‐High Frequency Ultrasound Imaging and Quantification of Microvascular Flow in Xenograft Renal Cell Carcinoma in an Avian Chorioallantoic Membrane Model

Journal of Ultrasound in Medicine, EarlyView.
Patient‐derived xenograft (PDX) tumor models initiated in avian chorioallantoic membranes (CAM) are under investigation to evaluate the effectiveness of therapeutic options with the objective of personalizing treatments. CAM PDXs paired with ultra‐high frequency ultrasound (UHFUS) imaging could potentially constitute prospective high throughput assays ...

Living on the edge: Habitat characteristics of northern myotis at the periphery of its distribution

The Journal of Wildlife Management, EarlyView.
Northern myotis selected tall trees with minimal decay, in patches with other roosting options. In our study area, these trees occurred in narrow bands within an agricultural matrix, differing from contiguous forest at the core of the species' distribution. Nevertheless, bats selected the tallest trees in the densest patches available.

A low-power asynchronous VLSI FIR filter [PDF]

, 2001
An asynchronous FIR filter, based on a Single Bit-Plane architecture with a data-dependent, dynamic-logic implementation, is presented. Its energy consumption and sample computation delay are shown to correlate approximately linearly with the total ...

Modeling effects of environmental conditions and hunter activity on Montezuma quail harvest in Arizona

The Journal of Wildlife Management, EarlyView.
Models of spatiotemporal variation in hunter harvest show that monsoon precipitation and changes in hunter behavior and composition are the primary drivers underlying variation in annual harvest of Montezuma quail. The demographic structure of the previous year's harvest was also strongly associated with the magnitude and rate of annual harvest ...

Experimental and Numerical Investigations of Glued Cross-Laminated Timber Beams Produced with Different Wood Species and Glues

BioResources
Five-layer cross-laminated timber (CLT) beams made from 17-mm thick lumber pieces were produced using wood from Scots pine (Pinus sylvestris L.), Uludağ fir (Abies bornmüelleriana Mattf.), and oak (Quercus petraea L.). The outer layers consisted of Scots
