The Lamb-Bateman integral equation and the fractional derivatives
, 2010 The Lamb-Bateman integral equation was introduced to study the solitary wave diffraction and its solution was written in terms of an integral transform. We prove that it is essentially the Abel integral equation and its solution can be obtained using the

Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing
Advanced Materials, EarlyView.Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.

Multifrequency Identification and Exploitation in Lamb Wave Inspection
IEEE Access, 2019 Lamb wave inspection provides a promising method to assess the structural health status. However, Lamb wave modes exhibit different characteristics which vary with frequency significantly.

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

The Suitability of Using 3D PLA Printed Wedges for Ultrasonic Wave Propagation
IEEE Access, 2020 This work studies the suitability of using 3D printed PLA wedges made through additive manufacturing to propagate Lamb waves in plate structures instead of using rather more expensive commercial wedges.

Air-coupled acoustic imaging with zero-group-velocity Lamb modes [PDF]
, 2003 A Lamb wave resonance has been found that allows unusually efficient transmission of airborne sound waves through plates. This occurs at the zero-group-velocity point at the frequency minimum of the first-order symmetric (S1 ) Lamb mode. At this frequency,

Did the Indian Green Revolution Change the Farm Size–Productivity Relationship?
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT We examine the relationship between farm size and productivity during India's Green Revolution, a period of rapid technological transformation. Using a unique panel of over 5000 Indian farm households that spans the Green Revolution (1971–1999), we show that the classic (linear) inverse farm size–productivity relationship gradually evolved ...

The spread of non‐native species
Biological Reviews, EarlyView.ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.
