Global gyrokinetic turbulence simulations of MAST plasmas [PDF]

, 2012
Electrostatic gyrokinetic analyses are presented for an L-mode discharge with an internal transport barrier, from the spherical tokamak, MAST. Local and global microstability analysis finds similar linear growth rates for ion temperature gradient (ITG ...

HMGCR‐Driven Cholesterol Metabolism Promotes Osteoarthritis Progression by Accelerating Synovial Fibroblast Senescence

Advanced Science, EarlyView.
In the pathological context of osteoarthritis (OA), the phosphorylation of AKT1 at Ser473 enhances its binding to Lys140 of Insig1, which facilitates the formation of AKT1–Insig1 complex. Subsequently, the activation of AKT1 promotes the phosphorylation of Insig1 at Ser189, potentially enhancing the dissociation of Insig1 from sterol regulatory element‑

Acorn Availability Reduces Agricultural Damage by Ungulates

Ecology and Evolution
Human–wildlife conflicts, particularly the damage to agricultural crops caused by ungulates, pose significant ecological and economic challenges. Understanding the role of natural food availability in driving these conflicts is important for developing ...

Reorganization of Innate Immune Cell Lipid Profiles by Bioinspired Meroterpenoids to Limit Inflammation

Advanced Science, EarlyView.
Resolution pharmacology is an emerging strategy to tackle inflammatory pathologies. Bioinspired meroterpenoids induce a lipid mediator class switch toward inflammation resolution in vitro and in vivo by targeting key nodes in lipid mediator biosynthesis and neutral lipid dynamics.

Identification of flowering-time genes in mast flowering plants using De Novo transcriptomic analysis.

PLoS ONE, 2019
Mast flowering is synchronised highly variable flowering by a population of perennial plants over a wide geographical area. High seeding years are seen as a threat to native and endangered species due to high predator density caused by the abundance of ...

Do Female Songbirds Avoid a Mammalian Nest Predator When Selecting Their Nest Site?

Frontiers in Ecology and Evolution, 2020
Perceived predation risk can elicit strong behavioral responses in potential prey. During nest building, songbirds exhibit anti-predator behaviors under experimental conditions.

Reproducing reproduction: How to simulate mast seeding in forest models [PDF]

Ecological Modelling, 2018
Masting is the highly variable and synchronous production of seeds by plants. Masting can have cascading effects on plant population dynamics and forest properties such as tree growth, carbon stocks, regeneration, nutrient cycling, or future species composition. However, massing has often been missing from forest models. Those few that simulate masting

Increasing spring temperatures favor oak seed production in temperate areas

Scientific Reports, 2017
The changes in reproductive phenology (i.e. timing of flowering and fruiting) observed in recent decades demonstrate that tree reproduction has already been altered by climate change.

Flower-fruit dynamics, visitor-predator patterns and chemical preferences in the tropical bamboo, Melocanna baccifera.

PLoS ONE, 2022
Mast seeding and associated events in Melocanna baccifera, the largest fruit producing bamboo, is an enigma. So far there are no comprehensive accounts on its flowering phenology, fruiting dynamics and animal interactions. In this study, spanning over 13
