Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Reward Processing in Binge Eating and Harmful Drinking: A Systematic Review

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Binge eating and harmful drinking commonly co‐occur, which worsens the physical and psychological consequences associated with either behavior alone. Reward processing alterations have been demonstrated among individuals who engage in binge eating or harmful drinking alone; however, there is limited understanding of how different ...

High-Titer Methane from Organosolv-Pretreated Spruce and Birch

open access: yesEnergies, 2017
The negative impact of fossil fuels and the increased demand for renewable energy sources has led to the use of novel raw material sources. Lignocellulosic biomass could serve as a possible raw material for anaerobic digestion and production of biogas ...

Increase in plant productivity in the tundra in Sweden is not related to increasing presence of warm‐adapted vascular plant species

open access: yesEcography, EarlyView.
Over the past decades, Arctic and alpine biomes have warmed faster than the global average. Substantial vegetation changes have been reported as a response to this warming, including increased productivity and the spread of warm‐adapted (thermophilic) species that are less resistant to grazing pressure into higher latitudes and altitudes.

Formation of Lignin Nanoparticles by Combining Organosolv Pretreatment of Birch Biomass and Homogenization Processes

open access: yesMolecules, 2018
Valorization of lignocellulosic biomass into a biorefinery scheme requires the use of all biomass components; in this, the lignin fraction is often underutilized. Conversion of lignin to nanoparticles is an attractive solution.

The dual influence of top‐down and bottom‐up processes on a mesopredator and the consequences for prey

open access: yesEcography, EarlyView.
Ecosystem dynamics are shaped by interacting top‐down and bottom‐up processes, yet their relative importance may vary through time following disturbances such as disease outbreaks and changes in apex predator communities. Using a 52‐year time series in south‐central Sweden, we examined how disease, apex predators, and prey availability jointly impact a

“The Golden Grove Has Finished Speaking...”: The Discovery of the Symbolic Russian Landscape by Russian Culture of the 19th and Early 20th Century

open access: yesHistoria provinciae: журнал региональной истории
The abundance of artists and writers whose works depict the images of birch figuratively or verbally is one of the main arguments put forward by some philologists and art historians in favor of the supposedly uninterrupted centuries-long tradition of ...
