Nodal degeneracy of guided modes in uniaxial crystal slabs

Frontiers in Physics, 2023
We study the dispersions of the guided modes in the continuous uniaxial crystal slab waveguide and engineer their degeneracies through dielectric anisotropy.

Analysis and design of link slabs in jointless ramp viaduct [PDF]

IOP Conference Series: Earth and Environmental Science, 2019
Abstract Due to the internal and external movement of the bridge deck, it is necessary to provide expansion gaps between multi span bridge decks. However the water leaking and debris trapped in the expansion joints will cause high maintenance cost. Therefore an alternative to eliminate expansion joints is vital.

The role of Rayleigh-Taylor instabilities in filament threads

, 2012
Many solar filaments and prominences show short-lived horizontal threads lying parallel to the photosphere. In this work the possible link between Rayleigh-Taylor instabilities and thread lifetimes is investigated.

Nodal-link semimetals [PDF]

, 2017
In topological semimetals, the valence band and conduction band meet at zero-dimensional nodal points or one-dimensional nodal rings, which are protected by band topology and symmetries.

Design and Construction of UHPC Link Slabs

Second International Interactive Symposium on UHPC, 2019
The installation of UHPC link slabs provides a highly durable, minimally intrusive retrofitting technique that eliminates problematic deck joints from non-continuous bridge superstructures. UHPC link slabs can also be used on new bridges to eliminate deck joints where superstructure continuity is not desirable for structural reasons.

Normal‐Appearing White Matter Injury Mediates Chronic Deep Venous Hypoxia and Disease Progression in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To explore how cerebral hypoxia and Normal‐Appearing White Matter (NAWM) integrity affect MS lesion burden and clinical course. Methods Seventy‐nine MS patients, including 13 clinically isolated syndrome (CIS) patients and 66 relapsing–remitting multiple sclerosis (RRMS) patients, and 44 healthy controls (HCs) were recruited from ...

Experimental and numerical study of road-bridge link slabs in fully jointless bridges using rubberized engineered cementitious composites (R-ECC)

Case Studies in Construction Materials
This paper presents a different way using crumb rubber and fine sand totally replaced for silica sand within ECC mixtures to make rubberized engineered cementitious composites (R-ECC) to solve the issues of high construction cost of the road-bridge link ...
