Gas lasers with wave-chaotic resonators

open access: yes, 2010
Semiclassical multimode laser theory is extended to gas lasers with open two-dimensional resonators of arbitrary shape. The Doppler frequency shift of the linear-gain coefficient leads to an additional linear coupling between the modes, which, however ...

The International Guideline for the Definition, Classification, Diagnosis and Management of Urticaria

open access: yesAllergy, EarlyView.
ABSTRACT This update and revision of the international guideline for urticaria was developed in accordance with the methods recommended by Cochrane and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) working group. It is an initiative of the Global Allergy and Asthma Excellence Network (GA2LEN) and its Urticaria and ...

Clamping Resonators for Low-Frequency S0 Lamb Wave Reflection

open access: yesApplied Sciences, 2019
A recent elastic metamaterial study found that resonators that “clamp” a plate waveguide can be used to create a frequency stop-band gap. The result was that the resonator array can prohibit the propagation of an A0 Lamb wave mode. This study

Crack Detection with Lamb Wave Wavenumber Analysis [PDF]

open access: yes, 2013
In this work, we present our study of Lamb wave crack detection using wavenumber analysis. The aim is to demonstrate the application of wavenumber analysis to 3D Lamb wave data to enable damage detection.

The Rayleigh-Lamb wave propagation in dielectric elastomer layers subjected to large deformations

open access: yes, 2011
The propagation of waves in soft dielectric elastomer layers is investigated. To this end incremental motions superimposed on homogeneous finite deformations induced by bias electric fields and pre-stretch are determined.

Brokers, Collaborators and Knowledge Translators: Expanding the Role of Research Assistants in Geographic Research

open access: yesAsia 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.

Maximal Acceleration Corrections to the Lamb Shift of Muonic Hydrogen [PDF]

open access: yes, 1998
The maximal acceleration corrections to the Lamb shift of muonic hydrogen are calculated by using the relativistic Dirac wave functions. The correction for the $2S-2P$ transition is $\sim 0.38$ meV and is higher than the accuracy of present QED ...
