Sperm preparation techniques affect biological parameters, fertility indices, and DNA fragmentation in patients with oligo-astheno-teratozoospermia

Reproduction and Fertility
In normozoospermia, the albumin gradient filtration (AGF) and swim-up processing techniques are used to isolate spermatozoa with the highest biological parameters and specific sperm fertility indices (SSFI).

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion

Advanced Robotics Research, EarlyView.
This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...
