The Points Of Language

open access: yesHumana.Mente: Journal of Philosophical Studies, 2013
Signed languages display a variety of pointing signs that serve the functions of deictic and anaphoric pronouns, possessive and reflexive pronouns, demonstratives, locatives, determiners, body part labels, and verb agreement.

Yolngu Sign Language: An Undocumented Language of Arnhem Land [PDF]

open access: yes
Recently there has been an increase in studies documenting the world’s languages. Most of these studies concentrate on spoken languages but there is a growing effort to document sign languages. In this short paper we describe one of the many undocumented

Numerical Study on the Potential Enhancement of Organic Terahertz Sources through Tilted Pulse Front Pumping

open access: yesAdvanced Photonics Research, EarlyView.
In this article, two individually successful concepts, the tilted pulse‐front pumping technique and organic terahertz crystals for highly efficient THz generation are combined in the framework of numeric calculations resulting in increased conversion efficiency, increased damage threshold, and extended lifespan for ≈2 μm pumping.

Stimulated Raman Scattering with Optical Vortex Beams

open access: yesAdvanced Photonics Research, EarlyView.
This study presents exact analytical expressions for stimulated Raman scattering with Laguerre‐Gaussian beams, revealing signal dependence on topological and hyperbolic momentum. The results provide a theoretical foundation for coherent Raman imaging and detecting orbital angular momentum of light via structured light in nonlinear optics.
