Advanced Robotics Research, EarlyView.This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Numerical Modeling of Photothermal Self‐Excited Composite Oscillators
Advanced Robotics Research, EarlyView.We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.

Heat sink effects in variable polarity plasma arc welding [PDF]
The Space Shuttle External Tank is fabricated by the variable polarity plasma arc (VPPA) welding process. In VPPA welding, a noble gas, usually argon, is directed through an arc to emerge from the torch as a hot plasma jet.

Driver circuit for inductive loads [PDF]
, 1972 Circuit, based on use of power transistors which do not display second breakdown under valve loading, drives inductive loads. Peak voltages, power dissipations, heat sink requirements, and thermal stability considerations can be obtained by theoretical ...

Advanced Science, EarlyView.This study suggests that prenatal aspirin exposure is associated with reduced ovarian reserve in offspring, associated with HDAC1‐linked epigenetic downregulation of Usp9x as a candidate mechanism. These preclinical findings provide new insights into fetal‐origin ovarian disorders and contribute to the evidence base concerning aspirin's gestational ...

Design of a Heat Sink for an Electronic Component in ABB Drive using Different Types of Fins
MATEC Web of Conferences, 2018 This paper considers an analytical approach in the design of a passive heat sink for an ABB electrical drive. The heat sink is intended to dissipate a certain amount of heat energy and to maintain the surface temperature of an electronic communication ...

Advanced Science, EarlyView.The StERF10‐StGSH1 module coordinates glutathione (GSH) biosynthesis under low‐phosphorus stress. The low‐phosphate‐induced AP2/ERF transcription factor StERF10 directly activates the transcription of StGSH1 and enhances GSH accumulation. Consequently, GSH scavenges reactive oxygen species and provides sulfur for sulfolipid synthesis, facilitating the ...
