Recent trend reversal for declining European seagrass meadows

open access: yesNature Communications, 2019
Seagrass meadows, key ecosystems supporting fisheries, carbon sequestration and coastal protection, are globally threatened. In Europe, loss and recovery of seagrasses are reported, but the changes in extent and density at the continental scale remain ...

Restoring Blood Pressure in Hypertensive Mice Fails to Fully Reverse Vascular Stiffness

open access: yesFrontiers in Physiology, 2020
BackgroundHypertension is a well-established driver of vascular remodeling and stiffening. The goal of this study was to evaluate whether restoring normal blood pressure (BP) fully restores vascular stiffness toward that of normotensive controls ...

Invariant curves of low smooth quasi-periodic reversible mappings [PDF]

open access: yesarXiv, 2023
In this paper, we obtain the invariant curves of quasi-periodic reversible mappings with finite smoothness. Since the reversible property is difficult to maintain in the process of approximating smooth functions by analytical ones, R\"{u}ssmann's method in \cite{HR} is invalid.

Phase Reversal Diffraction in incoherent light

open access: yes, 2009
Phase reversal occurs in the propagation of an electromagnetic wave in a negatively refracting medium or a phase-conjugate interface. Here we report the experimental observation of phase reversal diffraction without the above devices.

Causal Reversibility Implies Time Reversibility

open access: yes, 2023
Several notions of reversibility exist in the literature. On the one hand, causal reversibility establishes that an action can be undone provided that all of its consequences have been undone already, thereby making it possible to bring a system back to a past consistent state.

Pro- and Anti-fibrogenic Functions of Gram-Negative Bacterial Lipopolysaccharide in the Liver

open access: yesFrontiers in Medicine, 2020
Extensive research performed over several decades has identified cells participating in the initiation and progression of fibrosis, and the numerous underlying inter- and intra-cellular signaling pathways.

Evaluation of Pregnancy Outcome and Influencing Factors of Microsurgical Tubal Recanalisation as a Reversal of Tubal Ligation in a Tertiary Hospital

open access: yesAsian Journal of Medical Sciences, 2022
Background: Tubal microsurgical recanalization is a procedure which restores the fertility in women who have undergone sterilization voluntarily, thinking that her family is complete.

Dynamics of Spontaneous Magnetization Reversal in Exchange Biased Heterostructures

open access: yes, 2006
The dependence of thermally induced spontaneous magnetization reversal on time-dependent cooling protocols was studied. Slower cooling and longer waiting close to the N\`{e}el temperature of the antiferromagnet ($T_N$) enhances the magnetization reversal.

Cup Reversal in a Steroid Responder Post-Trabeculectomy

open access: yesDelhi Journal of Ophthalmology, 2019
An 18 year old male presented with diminution of vision in right eye since 4 days. Fundus of the right eye examination revealed a cup disc ratio of 0.4:1 and occlusion of superior and inferior branch retinal vein.
