Sliderule-like property of Wigner's little groups and cyclic S-matrices for multilayer optics

, 2003
It is noted that two-by-two S-matrices in multilayer optics can be represented by the Sp(2) group whose algebraic property is the same as the group of Lorentz transformations applicable to two space-like and one time-like dimensions.

Optical near-fields & nearfield optics

Beilstein Journal of Nanotechnology, 2014
Optical methods provide exceedingly powerful tools in science and technology for measuring, analyzing and manipulating, from optical microscopy and spectroscopy to the characterization of ultrafast processes by femtosecond pulses and the modification of materials by intense laser radiation. However, when it comes to applications in the nanometer-regime,

Molecular characterisation of human penile carcinoma and generation of paired epithelial primary cell lines

Molecular Oncology, EarlyView.
Generation of two normal and tumour (cancerous) paired human cell lines using an established tissue culture technique and their characterisation is described. Cell lines were characterised at cellular, protein, chromosome and gene expression levels and for HPV status.

Transmission Raman Spectroscopy for Inner Layers Chemical Analysis of Fresh Produce

Sensors
Identification of chemical properties in the inner tissues of fresh produce would enable us to identify major issues plaguing the agriculture supply chain, like off-flavors and core rot since these are caused by or accompanied by known chemical elements.

Strength through diversity: how cancers thrive when clones cooperate

Molecular Oncology, EarlyView.
Intratumor heterogeneity can offer direct benefits to the tumor through cooperation between different clones. In this review, Kuiken et al. discuss existing evidence for clonal cooperativity to identify overarching principles, and highlight how novel technological developments could address remaining open questions.

Microwaves by spark. Optical experiments with microwaves produced with a home-made equipment

Revista Eureka sobre Enseñanza y Divulgación de las Ciencias, 2011
La teoría del campo electromagnético fue el gran logro unificador del siglo XIX. Los experimentos de Hertz probaron la validez de la teoría y mostraron la existencia de otras ondas distintas a la luz pero con sus mismas propiedades.
