On Quantum Field Theory with Nonzero Minimal Uncertainties in Positions and Momenta [PDF]

open access: yes, 1996
We continue studies on quantum field theories on noncommutative geometric spaces, focusing on classes of noncommutative geometries which imply ultraviolet and infrared modifications in the form of nonzero minimal uncertainties in positions and momenta ...

Quasars and the Big Blue Bump [PDF]

open access: yes, 2004
We investigate the ultraviolet-to-optical spectral energy distributions (SEDs) of 17 active galactic nuclei (AGNs) using quasi-simultaneous spectrophotometry spanning 900-9000 Angstrom (rest frame).

Breakthroughs in photonics 2012: Nano-structuring and nano-fabrication enabled by extreme ultraviolet laser sources

open access: yesIEEE Photonics Journal, 2013
Two- and three-dimensional structures with submicron dimensions, such as photonic crystals, patterned magnetic media, micro- and nano-electromechanical systems (MEMs/NEMs), microfluidics chips, etc., are becoming ubiquitous in multiple applications ...

EGFR Activation and Ultraviolet Light-Induced Skin Carcinogenesis

open access: yesBMC Bioinformatics, 2006
BackgroundSelection of relevant genes for sample classification is a common task in most gene expression studies, where researchers try to identify the smallest possible set of genes that can still achieve good predictive performance (for instance, for ...

The effect of UV-B radiation on the chlorophyll fluorescence parameters of the husked and the naked oat

open access: yesActa Agrobotanica, 2013
Naked oat variety of STH296 showed higher tolerance than traditional variety Bajka on short-term UV-B radiation (UV-BBE=1 1 kJ·m-2) on the stage of primary photosynthesis reaction recorded using chlorophyll fluorescence induction of the leaves.

K-Corrections and Filter Transformations in the Ultraviolet, Optical, and Near-Infrared [PDF]

open access: yes, 2006
Template fits to observed galaxy fluxes allow calculation of K-corrections and conversions among observations of galaxies at various wavelengths. We present a method for creating model-based template sets given a set of heterogeneous photometric and ...
