Elastic metagratings enabling independent and complete control of both reflection and ROMPERS transmission of bulk longitudinal and transverse waves are highly desired in application scenarios such as non-destructive assessment and structural health monitoring.In this work, we propose a kind of simply structured metagrating composed only of ellipti
Herpes zoster and meningitis in an immunocompetent child: a case report
Abstract Background Development of neurological complications of varicella zoster virus reactivation is relatively uncommon, particularly in an immunocompetent child.Case presentation An 11-year-old Asian girl presented with headache and skin rash on her left chest.She was diagnosed with meningitis, and herpes zoster was confirmed by polymerase cha
Iceberg-seabed interaction evaluation in clay seabed using tree-based machine learning algorithms
In Arctic offshore regions, the oil and gas hydrocarbons are transferred to the onshore basins through the subsea pipelines.However, the operational integrity of the subsea pipeline may be at risk of collision with traveling icebergs, which gouge the seabed in the Arctic shallow waters.Even though these sea bottom-founded structures are buried at a
