Comparative Study of Thermal Lens Effect in End Pulsed-Pumped Ceramics and Single Crystal Yb3+ YAG- Cr4+ YAG Passively Q-switched Microchip Laser. [PDF]
In this work, different thermal lens focal lengths with different pumping repetition rates for ceramic and single crystal Yb:YAGare calculated for controlling the thermal focal length without using additional optical elements .

Calculation of 3D Coordinates of a Point on the Basis of a Stereoscopic System
The solution of three-dimensional (3D) coordinate calculation task for a material point is considered. Two flat images (a stereopair) which correspond to the left and to the right viewpoints of a 3D scene are used for this purpose.

Adaptive Lenses Based on Soft Electroactive Materials
Soft electroactive materials including dielectric elastomer actuators (DEAs) and polyvinyl chloride (PVC) gels have recently been extensively investigated. These smart materials can effectively respond to an electric field, resulting in shape deformation.

Copper laser patterning on a flexible substrate using a cost-effective 3D printer
We studied the cost effective direct laser patterning of copper (Cu) on thin polyimide substrates (PI thickness: 12.5–50 µm) using a 405 nm laser module attached to an inexpensive 3D printer.

Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
