Nonlinear Lamb wave mixing for assessing localized deformation during creep

NDT & E international, 2018
Nonlinear ultrasonic is known to be a promising technique to characterize the microstructural degradation in engineering materials. This work demonstrates the use of nonlinear Lamb wave mixing technique to assess the localized deformation in modified 9Cr

Morphological and Morphometric Analysis of Animal Hair From 18th Century Burial Sites in Mazamet (Southwest France)

Archaeometry, EarlyView.
ABSTRACT Morphological and morphometric analysis of archaeological animal hairs offers a nondestructive method to explore past clothing. We examined hair from two 18th‐century burial areas (SP03 and SP04) in Mazamet, France. SP03 specimens exhibited a continuous medulla, a low medullary index (0.2 ± 0.03) and cuticular features suggesting goat or ...

Multi-Wave Structures of Traveling Ionospheric Disturbances Associated with the 2022 Tonga Volcanic Eruptions in the New Zealand and Australia Regions

Remote Sensing
Using dense global navigation satellite system data and brightness temperature data across the New Zealand and Australia regions, we tracked the propagation of traveling ionospheric disturbances (TIDs) associated with the 15 January 2022 Tonga volcanic ...

Integrated Structural Health Assessment Using Piezoelectric Active Sensors

Shock and Vibration, 2005
This paper illustrates an integrated approach for identifying structural damage. The method presented utilizes piezoelectric (PZT) materials to actuate/sense the dynamic response of the structures.

Non-Semisimple Degeneracy of Lamb Waves

Mechanics of Solids
Abstract Anomalous guided waves appearing at a non-semisimple degeneracy of the fundamental matrix are observed and analyzed in the framework of the Cauchy sextic formalism. The non-semisimple degeneracy condition is explicitly constructed for the most general case of Lamb waves propagating in a traction-free layer with

Conversational Democracy: Facilitating Children's ‘Unprompted Talk’ in Social Work Dialogues

Child &Family Social Work, EarlyView.
ABSTRACT In child and family social work dialogues, social workers address topics that are relevant to children's well‐being and safety. In doing so, they inevitably prioritize one conversational direction over another. This means that while one topic is being addressed, other possible topics are put on hold or are simply never developed.

A Lamb Wave Wavenumber-Searching Method for a Linear PZT Sensor Array

Sensors, 2019
In this paper, a wavenumber−searching method based on time-domain compensation is proposed to obtain the wavenumber of the Lamb wave array received signal.

“Like a roller‐coaster ride”: Fathers' perspectives about their role in childcare

Family Relations, EarlyView.
ABSTRACT Objective This study qualitatively explores fathers' perceptions of their parenting role, as well as the challenges and resources associated with it. Background Societal changes in recent years have led to a transformation in the father's role, with fathers playing an integral role in shaping family dynamics and children's development.

The hidden science of haptics: A pedagogical review of tactile evaluation in cosmetics

International Journal of Cosmetic Science, EarlyView.
This review explores the physiological basis of tactile perception and critically examines classical and emerging sensory methods used in cosmetics, advocating for broader methodological integration and recognition of sensory analysis in the field. Abstract Sensory analysis is a cornerstone of cosmetic development, yet remains underrepresented in peer ...

Isolated in the highlands, found in the museum: A new species of Characidium (Crenuchidae) from a Bolivian National Park, with a CT scan revealing features

Journal of Fish Biology, EarlyView.
Abstract A new species of Characidium is described from a small, isolated river in the highland areas of Noel Kempff Mercado National Park, Bolivia. The new taxon can be diagnosed by the presence of a relatively broad and conspicuous dark midlateral stripe extending from the tip of snout to the base of the caudal fin, markedly darker than the vertical ...
