Equation of state effects on gravitational waves from rotating core collapse [PDF]

, 2017
Gravitational waves (GWs) generated by axisymmetric rotating collapse, bounce, and early postbounce phases of a galactic core-collapse supernova are detectable by current-generation gravitational wave observatories.

Autonomous Spatiotemporal Regulation of Reversible Hydrogel Actuators by Chemical Reaction Networks

Advanced Materials, EarlyView.
Hydrogel actuators with reversible response to thiols are developed using reversible binding of thiols to Michael acceptors. Autonomous spatiotemporal regulation of reversible movement of these hydrogels is achieved using thiol‐based chemical reaction networks containing both positive and negative feedback.

Systematic study of the stochastic gravitational-wave background due to stellar core collapse [PDF]

, 2017
Stellar core collapse events are expected to produce gravitational waves via several mechanisms, most of which are not yet fully understood due to the current limitations in the numerical simulations of these events.

Enhancing Grayscale E‐Beam Lithography: Thermal Treatment of Novolak‐Based Resist for 3D Nanostructures

Advanced Materials Interfaces, EarlyView.
Surface roughness and chemistry of novolak‐based grayscale resists are dependent on both exposure dose and post‐exposure thermal treatment. The observed trends align with the viscoelastic phase separation model and underscore the need to consider both thermodynamic and kinetic factors in resist processing. By tailoring thermal treatment, it is possible

Does a primary hair have an impact on the naked singularity formation in hairy Vaidya spacetime?

Physics of Complex Systems
We consider the gravitational collapse of Vaidya spacetime, which has been obtained using the gravitational decoupling method. In this paper, we are interested in whether a primary hair has any impact on the endstate of the gravitational collapse.

Gravitational collapse and formation of regular black holes: Dymnikova, Hayward, and beyond

European Physical Journal C: Particles and Fields
The gravitational collapse of a star can lead to the formation of a regular black hole. However, a key factor in this process is the transition of ordinary baryonic matter into a substance that forms the de Sitter core.

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

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.
