Ship roll damping via direct inverse neural network control system

Alexandria Engineering Journal, 2018
Undesired roll motions of surface vessels under sea way have negative influence on passengers, crew members, equipment and cargo. Damping roll motions is a complex problem due to unpredictable and irregular nature of marine environmental disturbances ...

Rogue Waves: From Nonlinear Schrödinger Breather Solutions to Sea-Keeping Test [PDF]

, 2013
Under suitable assumptions, the nonlinear dynamics of surface gravity waves can be modeled by the one-dimensional nonlinear Schrödinger equation. Besides traveling wave solutions like solitons, this model admits also breather solutions that are now ...

Spatial Transcriptomics of TMJ Reveals a Remodeling Fibroblast‐Immune Microenvironment Driving Arthritis Pain

Advanced Science, EarlyView.
Spatial transcriptomics reveals a remodeled fibroblast‐immune microenvironment in the temporomandibular joint (TMJ) during arthritis. By combining seqFISH with genetic mouse models, this study uncovers TMJ spatial cell atalas, macrophage‐fibroblast crosstalk, and cytokine signaling pathways driving TMJ inflammation and pain.

Interface Engineering Suppresses Self‐Annealing in Electroplated Nanograined Copper for Low‐Temperature Copper‐to‐Copper Bonding

Advanced Science, EarlyView.
A (111)‐oriented nanotwinned copper substrate stabilizes the deposited nanograined copper and prevents self‐annealing by restricting grain boundary motion at the interface and promoting the formation of stacking faults within the nanograined copper. Its preserved nanostructure maintains bonding capability even after 30 days of storage, resulting in ...
