Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

open access: yesLaser &Photonics Reviews, EarlyView.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Laser Stabilized to a Fiber Interferometer With Close‐To‐Zero Temperature Sensitivity

open access: yesLaser &Photonics Reviews, EarlyView.
A laser stabilized to a hollow‐core fibre interferometer is presented. The interferometer is designed to have near‐zero temperature phase‐sensitivity. Laser stabilized to this interferometer put in a non‐vacuum environment achieves ±550 kHz frequency variation over 100 h and an Allan deviation of 2 × 10−14τ, which is comparable to miniature ULE ...

Recent Developments in Sustainable Composites for Printed Circuit Boards (PCBs): A Review

open access: yesMacromolecular Materials and Engineering, EarlyView.
This review presents the potential of using natural plant fibers and biodegradable polymers as sustainable printed circuit boards (PCBs). This review provides future directions in innovation and sustainable PCBs development. Bio‐composites PCBs are both environmentally friendly and sustainable due to the natural fibres they contain.

Total X‐Ray Illumination for Absolute Quantification of Crystalline Phases and Amorphous Content in PVDF and P(VDF‐TrFE)

open access: yesMacromolecular Materials and Engineering, EarlyView.
A rigorous method, Total Illumination by X‐rays (TIX), is presented to quantify crystalline and amorphous phases in organic materials. Mitigating challenges such as low microabsorption and high amorphous content, an improved, general framework is established, applicable to polymers, MOFs, biological materials, etc.

A new Palaeolithic chipped stone tool technology from Southeast Anatolia: the Haydar tool

open access: yes
Abstract During the Palaeolithic, a wide variety of tool technologies and typologies are known to have emerged. Some of those technologies were used over large areas for long periods, while others were geographically restricted and more regionalized.

Parkinson's Disease Patient‐Specific Striatum Organoids Show Hallmarks of Increased Inflammation

open access: yesMovement Disorders, EarlyView.
Abstract Background Dopaminergic neurons from the substantia nigra pars compacta project their axons into the dorsal striatum, forming the nigrostriatal pathway. In Parkinson's disease (PD), dopaminergic terminals degenerate in the striatum, leading to dopamine depletion, which in turn causes alterations in the basal ganglia circuits that are essential

Hederagenin Attenuates Cardiac Remodeling by Targeting Phosphodiesterase 9A

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Background and Aim New therapeutic strategies for heart failure are urgently needed. The protective effects of cyclic guanosine monophosphate (cGMP)—protein kinase G (PKG) pathway on heart have been widely reported. Despite phosphodiesterase 9A (PDE9A) inhibitors combating cardiac remodeling, clinically available drugs are lacking. Hederagenin
