Mitochondrial Haplotype Shapes the Trajectory of Ovarian Aging in Genetically Heterogeneous Rats

open access: yesAging Cell, Volume 25, Issue 9, September 2026.
Using genetically heterogeneous rats carrying divergent mitochondrial haplotypes on a randomized nuclear background, we show that mtDNA variation modifies the rate of ovarian aging. OKC‐HETW ovaries showed bioenergetic deficits, reduced mtDNA copy number, and impaired TFAM–mtDNA binding by 4 months of age, with early fibrosis and immune infiltration ...

Direct generation of orthogonally polarized photon pairs on a chip via spontaneous non-degenerate FWM

open access: yes, 2014
By suppressing stimulated processes, we demonstrate the direct generation of orthogonally polarized photon pairs via spontaneous non-degenerate four-wave-mixing (FWM) between orthogonally polarized pumps in a CMOS-compatible micro-ring.

Three Methods of Fetal Weight Estimation Compared in Women With BMI ≥ 35 kg/m2 at Term—A Prospective Observational Study

open access: yesBirth, Volume 53, Issue 3, Page 491-496, September 2026.
Visual summary of a prospective study comparing sonographic, maternal, and clinical fetal‐weight estimation methods in women with BMI = 35 kg/m2 at term. The graphical abstract presents the study objective, design, accuracy measures, and the primary finding that maternal and sonographic estimations demonstrated similar accuracy and both exceeded that ...

Preserving global optical QoS in FWM impaired dynamic networks

open access: yes, 2015
Optical quality of service (QoS) provisioning under the intricacy of four wave mixing (FWM) lightpaths interaction is tackled through connection admission control-routing and wavelength assignment (CAC-RWA) integration.

Performance analysis of nonlinear crosstalk of WDM systems using modulation schemes criteria

open access: yesOpen Engineering
Nonlinearities in optical fibers are regarded as the most significant barriers that endanger the effectiveness of the optical transmission system and pose a threat to communication quality.

Biomimicry of the Hawk Moth, Manduca sexta (L.), Produces an Improved Flapping-Wing Mechanism

open access: yesBiomimetics, 2020
Flapping-wing micro air vehicles (FWMAVs) that mimic the flight capabilities of insects have been sought for decades. Core to the vehicle’s flight capabilities is the mechanism that drives the wings to produce thrust and lift.

Impact of TCAs and Gabapentin on Saliva and BMI in Adults With Xerostomia

open access: yesJournal of Oral Rehabilitation, Volume 53, Issue 9, Page 1694-1702, September 2026.
In adults with medication‐related xerostomia, tricyclic antidepressant and gabapentin use were not independently associated with BMI or oral dryness after adjustment. Instead, female sex, anticholinergic burden, obstructive sleep apnea, GERD, thyroid disease, depression and race demonstrated stronger associations with reduced salivary flow and greater ...

Enhanced FWM in SiN waveguides with GO films Advanced Optical Materials

open access: yes, 2023
Layered 2D graphene oxide (GO) films are integrated with silicon nitride (SiN) waveguides to experimentally demonstrate an enhanced Kerr nonlinearity via four-wave mixing (FWM).

L‐Glutamine Plus L‐Glutamic Acid Enhances Antioxidant Status and Ammonia Toxicity Resilience, Upregulates Interleukin IL‐10 Gene, and Improves Gut Microbiota and Survival in Juvenile Nile Tilapia

open access: yesJournal of Animal Physiology and Animal Nutrition, Volume 110, Issue 5, Page 715-730, September 2026.
ABSTRACT Glutamine (Gln) and glutamic acid (Glu) are the most abundant free amino acids (AAs) in the fish body. Although classified as non‐essential AAs, their supplementation can be a strategy to optimize the growth performance and health of fish.

Interferograms of Votex FWM Beam for Nonlinear Spatial Filter in Photonic Band Gap

open access: yesIEEE Photonics Journal, 2019
We analyze the properties and interferograms of vortex four-wave mixing (FWM) beams by varying the incident angle of the probe field. Based on the properties, we propose the model of a new type of nonlinear spatial filter without diffraction using a ...
