Analytical model for polarization-dependent light propagation in waveguide arrays and applications (American Physical Society, 2014)© 2014 American Physical Society. We study the polarization properties of elliptical femtosecond-laser-written waveguide arrays. An analytical model is presented to explain the asymmetry of the spatial transverse profiles ...
-
(University of Szeged, 2014)Abstract. In this work, using discontinuous almost periodic type functions, exponential dichotomy and the notion of Bi-almost automorphicity we give sufficient conditions to obtain a unique almost automorphic solution of ...
-
(2014)In this work, the dynamics of the clusters of the type M3 with M a metal alkaline atom from Li to Cs have been studied. Other heteroatomic mixed clusters like LiNaK and one bigger cluster, Na7, have also been studied. It ...

(Wiley, 2014)Parasitic plants often have a strong fitness-impact on their plant hosts through increased host mortality and reduced or complete suppression of reproduction. Tristerix corymbosus (Loranthaceae) is a hemiparasitic mistletoe ...
-
(Springer Verlag, 2014)© 2014, The Author(s).There is a consensus that birds detect the earth’s magnetic field and use some of its features for orientation and homing purposes. Since the late 1960s, when the first solid behavioral evidence of ...
-
(Interciencia Association, 2014)During the last decades, climatic variations in the Chilean Higlands (Altiplano) that threaten the sustainability of the local wetlands and, thus, the sustainability of farming practices that depend on them, have been ...
-
(Natural Product Incorporation, 2014)Ethanol extracts from dried leaves of wild Lepechinia salvia (Lindl) Epling, collected during the flowering period (September-November), contained 15% to 25% carnosic acid and 2 to 8% carnosol, depending on the month of ...

Electronic spectra of d-ph-d’ systems. 1.aminophenol cations as isoelectronic structures of cresols (1990)The electronic absorption spectra and luminescent properties in the first singlet π-π* excited states of aminophenol cations in aqueous solutions are studied from a theoretical and experimental point of view. Lifetime and ...
-
(1988)A normal coordinate analysis has been carried out for the series Cs2NaLnCl6, where Ln represent a trivalent lan thanide cation such as Pr+ 3, Sm+3, Eu+3, Tb+ 3, Ho+3and Tm+3by using a general valence force field (GVFF). A ...
-
(American Physical Society, 2014)© 2014 American Physical Society. We show that, after a transformation, the dynamics of linear perturbations (spin waves) around a singular Bloch point soliton is formally equivalent to a quantum system of an electron in ...
-
(Regional Euro-Asian Biological Invasions Centre, 2014)© 2014 REABIC. Aquatic invasive species are a major threat to native freshwater ecosystems and cause enormous ecological and economic damage worldwide. Didymosphenia geminata (Lyngbye) M. Schmidt is an emerging invasive ...
