Experimental and theoretical studies of sea ice effects on internal solitary waves

Frontiers in Marine Science
Internal solitary waves in polar regions have attracted much interest recently. It is important to understand how sea ice affects them as this may have a profound influence on human activities and the environment.

Internal solitary wave transformation over the slope: Asymptotic theory and numerical simulation

Journal of Ocean Engineering and Science, 2018
The propagation and evolution of long nonlinear internal solitary waves over slope-shelf topography is theoretically and numerically studied in a two-layer fluid system of finite depth. The variable Korteweg–de Vries (vKdV) and variable extended Korteweg–

Hydrodynamics of internal solitons and a comparison of SIR-A and SIR-B data with ocean measurements [PDF]

Large internal solitary waves have been observed by Shuttle SIR-A and SIR-B at locations in the Andaman Sea and the New York Bight. Satellite imagery and oceanographic measurements are used in conjunction with hydrodynamic interaction and electromagnetic

Efficient Harvesting of Irregular and Low‐Frequency Mechanical Energy via Hybridized Electromagnetic‐Triboelectric Systems

Small, EarlyView.
ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the

Breaking Inversion Symmetry via Vanadium Coordination Engineering in Bismuth Vanadium Selenites

Small, EarlyView.
Vanadium coordination engineering induces symmetry breaking in bismuth selenites by transforming symmetry‐compensated VO6/VO5F units into directionally aligned VO5 polyhedra. The resulting non‐antiparallel vanadyl arrangement eliminates dipole cancellation and stabilizes a polar noncentrosymmetric framework with nonlinear optical activity.

EXPERIMENTAL STUDY OF INTERNAL SOLITARY WAVES INTERACTION WITH SURFACE SOLITARY WAVES

Coastal Engineering Proceedings
Internal solitary waves (ISWs) consist of a non-periodic single-crest profile resulting from the balance between non-linearity and dispersion. They can be a significant source of momentum transport in any stratified systems, such as oceans and estuaries. Previous experiments have primarily utilized lock- release mechanisms to generate internal solitary

Ba[C(CN)3]2 and Pb[C(CN)3]2: Two Remarkably Different Heavy Main‐Group Metal Bistricyanomethanides

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Metathesis reactions of either barium dichloride, BaCl2, or lead dichloride, PbCl2, respectively, with Ag[C(CN)3] in water yielded single crystals of anhydrous Ba[C(CN)3]2 and Pb[C(CN)3]2. Ba[C(CN)3]2 crystallizes in the monoclinic space group P21/n (no. 14) with the lattice parameters a = 437.98(3) pm, b = 1685.36(11) pm, c = 1398.87(9) pm, β = 96.541(

Boredom, despondency, and the scourge that lays waste at noon: an anthropology of acedia Ennui, abattement et le fléau qui frappe à midi : une anthropologie de l'acédie

Journal of the Royal Anthropological Institute, EarlyView.
Attentive to the ways that inertia can take hold of life, Catholic monks recognize despondency as a potential not only within the monastery, but in contemporary society more widely. Such experiences are regularly mapped onto an understanding of what early Christian monks termed ‘acedia’ (a Greek term that can be translated as ‘lack of care’). Taking as

Transformation of mode-2 internal solitary wave over a pseudo slope-shelf

AIP Advances, 2017
Numerical simulations are performed to investigate the effect of wave amplitude in a numerical wave tank on the evolution of a convex mode-2 internal solitary wave (ISW) propagating over a pseudo slope-shelf.

Collision of water wave solitons

, 2013
A classification of the time evolution of the two-soliton solutions of the Boussinesq equation is given, based on the number of extrema of the wave. For solitons moving in the same directions, three different scenarios are found, while it is shown that ...
