WFS1 Deficiency Impairs PIAS4‐Associated SUMOylation and Increases Ubiquitin‐Mediated Spermatogenesis‐Related Protein Degradation Leading to Testicular Male Infertility

Advanced Science, EarlyView.
The findings establish a critical role for WFS1 in human male fertility. Mechanistically, WFS1 interacts with PIAS4 to promote the SUMOylation of key spermatogenesis‐associated proteins, which in turn competitively inhibits their K48‐linked ubiquitin‐mediated degradation during spermatogenesis.

Enhanced Acoustic Adhesion Enabling Agile and Small Wall‐Climbing Robot Design With Anisotropic Origami Structure

Advanced Science, EarlyView.
This 28 g robot incorporates innovative ring structures and anisotropic origami springs to achieve high speeds and exceptional load capacity. It successfully carries a 100 g payload while ascending walls or ceilings at speeds of up to 8 and 20 cm/s, demonstrating enhanced adhesion and maneuverability over current climbing robots.

Properties and dynamics of generalized squeezed states

New Journal of Physics
We analyse the properties and dynamics of generalized squeezed states. We find that, in stark contrast to displacement and two-photon squeezing, higher-order squeezing leads to oscillatory dynamics.

Thermalization of squeezed states

, 2005
Starting with a thermal squeezed state defined as a conventional thermal state based on an appropriate Hamiltonian, we show how an important physical property, the signal-to-noise ratio, is degraded, and propose a simple model of thermalization (Kraus ...

High‐Efficiency InGaP‐on‐Insulator Microresonator Nonlinear Conversion and Entanglement Generation

Advanced Science, EarlyView.
Sulfur treatment of InGaP‐on‐Insulator (InGaP‐OI) significantly reduces surface roughness, passivates surface states, and lowers propagation loss at visible wavelengths, enabling efficient nonlinear frequency conversion and photon‐pair generation.

Habitat‐Specific Design Strategies for Untethered Soft Robots

Advanced Science, EarlyView.
Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...
