Constant-roll warm inflation within Rastall gravity
Nuclear Physics BThis research paper used a newly proposed strategy for finding the exact inflationary solutions to the Friedman equations in the context of Rastall theory of gravity (RTG), which is known as constant-roll warm inflation (CRWI).

American Journal of Botany, EarlyView.Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

Journal of High Energy PhysicsFibre inflationary models are constructed in type-IIB string flux compactification. These models have been shown to be in agreement with the cosmological observations under appropriate choices of parameters, which originate from their string theory ...

American Journal of Botany, EarlyView.Abstract Premise Climate change is altering the timing of many plant phenological events, yet most studies focus on flowering, with less attention given to later reproductive stages such as fruit development and ripening. Vaccinium angustifolium (lowbush blueberry) is an important perennial berry species that may be sensitive to these changes.

Coupled Quintessence Inspired by Warm Inflation
UniverseWe investigate a coupled quintessence cosmological model in which a dark-energy scalar field with an exponential potential interacts directly with a dark-matter fluid through a dissipative term inspired by warm inflation.

American Journal of Botany, EarlyView.Abstract Premise The origin of endemic species in the European Alps is commonly attributed to the climatic oscillations of the Quaternary. Moehringia sect. Moehringia, with 12 of 15 species endemic to the Alps and mostly restricted to well‐known glacial refugia, is a prime system for investigating the diversification of a lineage originating in the ...

Journal of Cosmology and Astroparticle PhysicsAbstract The warm inflationary scenario is investigated in the context of affine gravity formalism. A general framework is provided for studying different single-field potentials. Using the sphaleron mechanism we explain the continuous dissipation of the inflaton field into radiation, leading to the Γ = Γ0 T

Animal Models and Experimental Medicine, EarlyView.In this study, we established a novel mouse model of intracerebral hemorrhage (ICH) by stereotactically injecting thermosensitive PNIPAM hydrogel into the internal capsule to impose localized mechanical stress on the corticospinal tract, which provides a straightforward and reproducible tool for preclinical studies on focal mechanical stress–induced ...

Animal Models and Experimental Medicine, EarlyView.D‐limonene supplementation enhances testicular recovery following orchiopexy in a rat model of bilateral cryptorchidism. Treatment with D‐limonene reduces oxidative stress (↓MDA, ↑SOD, ↑GPx, ↑TAC), downregulates pro‐apoptotic proteins (↓TNF‐α, ↓BAX, ↓Caspase‐3), and upregulates anti‐apoptotic Bcl‐2 expression.

European Physical Journal C: Particles and Fields, 2017 The warm inflation scenario in view of the modified Chaplygin gas is studied. We consider the inflationary expansion to be driven by a standard scalar field whose decay ratio $$\Gamma $$ Γ has a generic power-law dependence with the scalar field $$\phi $$
