LAMB WAVES INTERFERENCE IN MAIN PIPELINES [PDF]
, 2019 In this paper, the influence of the interference of Lamb waves on their attenuation in the main pipeline was investigated. The main goal was to identify patterns in the formation of interference of Lamb waves when conducting acoustic emission control in ...

American Anthropologist, EarlyView.ABSTRACT The evolutionary study of human dispersal is a key topic in biological anthropology. However, recent research has revealed inconsistencies between molecular and anatomical data across different timescales and geographic regions. Despite increased interdisciplinary dialogue, these discordances are rarely analyzed in depth or interpreted for ...

On 3‐MMC: A Cathinone I Have Come to Know and Love
Anthropology of Consciousness, EarlyView.ABSTRACT This article attempts to complicate the mythology of a compound in a state of becoming. I will trace lightly its origins as a cultural disruptor and how I am implicated in this imperative. Introducing you to 3‐MMC will require multiple modes of storytelling and taking of liberties, drawing on literature reviews, practice‐based research, prose,

Nonlinear Lamb waves in plate/shell structures
, 2017 鉴于常规超声检测技术对分布式材料细微损伤和接触类结构损伤的检测效果不佳，近年来非线性超声技术逐渐引起广泛关注．超声波在板壳结构中通常以兰姆波的形式进行传播，然而由于兰姆波的频散及多模特性，使得非线性兰姆波的理论和实验研究进展缓慢．本文从经典非线性理论出发，总结了源于材料固有非线性诱发的非线性兰姆波的理论和实验两个方面的研究进展，并综述了兰姆波的二次谐波发生效应在材料损伤评价方面的若干应用；从接触声非线性理论出发，讨论了目前由于接触类结构损伤诱发的非线性兰姆波的研究现状 ...

Asia Pacific Viewpoint, EarlyView.ABSTRACT While ‘local’ research assistants (RA) often play a key role in knowledge production in fieldwork‐based disciplines like geography, their role and agency often remain silenced. This paper brings together scholarship in feminist geography and critical development studies to reposition RAs as brokers, collaborators, and knowledge translators.

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling
Computer Graphics Forum, EarlyView.Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.

A process‐temporal perspective on organizational paradoxes: A review and future research agenda
International Journal of Management Reviews, EarlyView.Abstract Scholars are increasingly studying paradox processes, yet insights remain disconnected, with limited discussion across studies’ perspectives. Consequently, research risks underutilizing valuable findings, thereby reducing both theoretical and practical progress.
