Modeling and characterization of photovaractor for microwave optoelectronics abstract [PDF]

open access: yes, 2001
Optical control of microwave circuits using photodiode junction capacitance variation due to optical illumination has some advantages such as simplicity and wide possibilities in application, high tuning range, accuracy, and speed.

Hubble Space Telescope Photometry of the Dwarf Spheroidal Galaxy ESO 410-G005 [PDF]

open access: yes, 2000
We present HST WFPC2 imaging of the nearby low-surface-brightness dwarf spheroidal galaxy ESO 410-G005, which has been resolved into stars for the first time. The resulting color-magnitude diagram for about 2500 stars shows a red giant branch branch with

Improving the chromatic dispersion tolerance in long-haul fibre links using the coherent optical orthogonal frequency division multiplexing [PDF]

open access: yes, 2010
Numerical simulations of the coherent optical orthogonal frequency division multiplexing modems are undertaken to investigate the effect of the adaptive modulation, the number of sub-carriers, the cyclic prefix (CP) length, the clipping ratio ...

Hot mantle upwelling across the 660 beneath Yellowstone [PDF]

open access: yes, 2012
P-to-s receiver functions mapped to depth through P and S body-wave tomography models image continuous 410 and 660 km discontinuities beneath the area covered by USArray prior to the year 2011. Mean depths to the 410 and 660 km discontinuities of 410 and

Interstellar dust in the BOOMERanG maps [PDF]

open access: yes, 2002
Interstellar dust (ISD) emission is present in the mm-wave maps obtained by the BOOMERanG experiment at intermediate and high Galactic latitudes. We find that, while being sub-dominant at the lower frequencies (90,150, 240 GHz), thermal emission from ISD

UK domestic energy contracts, the 28 day rule, and experience in Sweden [PDF]

open access: yes, 2004
In the UK, domestic customers must be able to terminate energy contracts at 28 days notice. This has been seen as a transitional protection for customers and for competition.

Two-parton twist-3 factorization in perturbative QCD

open access: yes, 2004
We prove collinear factorization theorem for the process $\pi\gamma^*\to\pi$ at the twist-3 level in the covariant gauge by means of the Ward identity, concentrating on the two-parton case.

Malaria-filaria coinfection in mice makes malarial disease more severe unless filarial infection achieves patency [PDF]

open access: yes, 2005
Coinfections are common in natural populations, and the literature suggests that helminth coinfection readily affects how the immune system manages malaria.

How costumers’ way of life influence the value co-creation [PDF]

open access: yes, 2020
Purpose: This article is a contribution to the understanding of how value arises in wellestablished markets, and under which circumstances actors integrate resources from different service ecosystems to generate value.

Causality and replication in concurrent processes [PDF]

open access: yes, 2003
The replication operator was introduced by Milner for obtaining a simplified description of recursive processes. The standard interleaving semantics denotes the replication of a process P, written !P, a shorthand for its unbound parallel composition ...
