Description of the inelastic collision of two solitary waves for the BBM equation

, 2008
We prove that the collision of two solitary waves of the BBM equation is inelastic but almost elastic in the case where one solitary wave is small in the energy space. We show precise estimates of the nonzero residue due to the collision.

Construction of Lean Coal Molecular Structure Model Based on Spectroscopic Characterization

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The chemical structure of coal exerts a profound influence on its properties and utilization pathways. A comprehensive analysis of coal's molecular structure is crucial for mitigating environmental pollution arising from coal combustion and improving the efficiency of coal utilization.

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

The Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

Solitary and Periodic Wave Solutions of Sasa–Satsuma Equation and Their Relationship with Hamilton Energy

Complexity, 2020
In this paper, we study the exact solitary wave solutions and periodic wave solutions of the S-S equation and give the relationships between solutions and the Hamilton energy of their amplitudes.

A dancing bear, a colleague, or a sharpened toolbox? The cautious adoption of generative artificial intelligence technologies in digital humanities research

Journal of the Association for Information Science and Technology, EarlyView.
Abstract The emergence of generative artificial intelligence (GenAI) is reshaping the research landscape and carries significant implications for Digital Humanities (DH), a field long intertwined with computational methods and technologies. This study examines how DH scholars are adopting and critically evaluating GenAI in their research. Drawing on an

Multiscaled Solitary Waves [PDF]

, 2017
Abstract. It is analytically shown how competing nonlinearities yield new multiscaled (multi humped) structures for internal solitary waves in shallow fluids. These solitary waves only exist for large amplitudes beyond the limit of applicability of the KdV equation or its usual extensions.

Autistic Children With Speech Onset Delay Show Reversed Bias in Spectral Versus Temporal Auditory Processing

Autism Research, EarlyView.
ABSTRACT A recent “hierarchical” reinterpretation of the neurological basis of autism suggests that in autism with early language delay, perceptual processing may be favored over the integration of transmodal information. This model is largely based on neuroimaging findings relating to visual processing, but predicts a corresponding reorganization in ...

Exact solitary wave and periodic wave solutions for a higher-order model describing nonlinear internal waves

上海师范大学学报. 自然科学版, 2018
A higher-order model describing nonlinear internal waves is governed by a partial differential equation system. By using the method of dynamical systems, in this paper, we show that there exist parameter groups such that this system has exact periodic ...

‘Where are the adults?’: Troubling child‐activism and children's political participation

British Educational Research Journal, EarlyView.
Abstract Children's political participation is a well‐established theme in childhood studies. In this article we offer an original account of child activism that takes into account the entangled and emergent aspect of children as activists. We begin with a historical and a conceptual review, noting the importance of mid‐20th century developments such ...

Numerical Simulation of Solitary Wave Induced Flow Motion around a Permeable Submerged Breakwater

Journal of Applied Mathematics, 2012
This paper presents a numerical model for the simulation of solitary wave transformation around a permeable submerged breakwater. The wave-structure interaction is obtained by solving the Volume-Averaged Reynolds-Averaged Navier-Stokes governing ...
