β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations
Advanced Biology, Volume 9, Issue 3, March 2025.Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Advanced Engineering Materials, EarlyView.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Realize a Gabor zone plate with zigzag zones
Optics ExpressZone plates have gained significant popularity in the field of X-ray applications. In order to overcome the inherent problem of multiple focal points in traditional Fresnel zone plates (FZPs), researchers have turned to designing Gabor zone plates (GZPs) with binary and sinusoidal transmission characteristics. The processing of sharp corners in various

Mantle Convection Moving Plates [PDF]
This demonstration models the manner in which the convection currents in the mantle of the Earth cause movement of the plates. Convection currents in the mantle were thought, for many years, to be solely responsible for plate tectonic movements, with the

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials
Advanced Engineering Materials, EarlyView.Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Diffraction Efficiency of Phase Type Zone-plate and Zone-plate Interferometer.
Journal of the Japan Society for Precision Engineering, 1996 ゾーンプレート干渉法,あるいはフィゾー干渉法と組み合わせたゾーンプレート干渉法では,鮮明な干渉じまを得るために,ゾーンプレートの回折効率を調節して,参照光と測定光の強度を同じにしなければならない.そこで位相型回折格子の各次数の回折効率を理論的に計算した.デューティ比と位相差を変えた格子の回折効率を検討したところ,実験と理論はほぼ一致した.この際,位相差の測定を正確に行うために,光変調素子を用いた透過物体の位相測定装置を作り,位相差の測定を行った.ゾーンプレートの回折効率の調節を位相差の操作で行った.回折効率の計算に基づき参照波面と測定波面の光強度が等しくなる条件のゾーンプレートを作り,透過光と回折光によるゾーンプレート干渉じまを鮮明にすることができた.また,フィゾー干渉法と組み合わせた干渉でも ...
