Search for anomalous quartic $ZZ\gamma\gamma$ couplings in photon-photon collisions [PDF]

open access: yes, 2016
The self-couplings of the electroweak gauge bosons are completely specified by the non-Abelian gauge nature of the Standard Model (SM). The direct study of these couplings provides a significant opportunity to test the validity of the SM and the ...

A Third-Order Differential Equation and Starlikeness of a Double Integral Operator [PDF]

open access: yes, 2011
Functions f(z)= z+E°2 anzn that are analytic in the unit disk and satisfy the differential equation f'(z) + azf"(z)+yz2f"(z) = g(z) are considered, where g is subordinated to a normalized convex univalent function h.

On the existence of global solutions for $T^{3}$-Gowdy spacetimes with stringy matter [PDF]

open access: yes, 2002
We show a global existence theorem for Einstein-matter equations of $T^{3}$-Gowdy symmetric spacetimes with stringy matter. The areal time coordinate is used. It is shown that this spacetime has a crushing singularity into the past. From these results we

Mycobacterium bovis in human population in four Central European countries during 1990-1999

open access: yesVeterinární Medicína, 2003
A survey on Mycobacterium bovis and M. tuberculosis in humans has been performed in four Central European countries (Croatia, the Czech Republic, Slovak Republic and Slovenia) during the years 1990 to 1999.

Does Hartigiola annulipes (Diptera: Cecidomyiidae) distribute its galls randomly?

open access: yesEuropean Journal of Entomology, 2018
It is expected that environmental conditions impact the distribution of galls on host plants. Moreover, insects may induce their galls randomly or choose certain parts of a host to induce such growths.

Smarandache Non-Associative (SNA-) rings [PDF]

open access: yes, 2005
In this paper we introduce the concept of Smarandache non-associative rings, which we shortly denote as SNA-rings as derived from the general definition of a Smarandache Structure (i.e., a set A embedded with a week structure W such that a proper subset ...

Homogeneous nucleation for Glauber and Kawasaki dynamics in large volumes at low temperatures [PDF]

open access: yes, 2008
In this paper we study metastability in large volumes at low temperatures. We consider both Ising spins subject to Glauber spin-flip dynamics and lattice gas particles subject to Kawasaki hopping dynamics. Let $\b$ denote the inverse temperature and let $

A new approach to using Diffusive Gradient in Thin-films (DGT) labile concentration for Water Framework Directive chemical status assessment: adaptation of Environmental Quality Standard to DGT for cadmium, nickel and lead

open access: yesEnvironmental Sciences Europe, 2023
Integrative passive samplers, such as DGT (Diffusive Gradients in Thin-films), are identified in European Technical Guidance Documents as promising tools to improve the quality of the assessment, in the context of the WFD (EU Water Framework Directive ...

Anomalous quartic $ZZ\gamma\gamma$ couplings at the CLIC

open access: yes, 2015
We study the sensitivity to anomalous quartic $ZZ\gamma\gamma$ couplings through the processes $e^{+}e^{-}\rightarrow Z\, Z\, \gamma$, $e^{+}e^{-} \rightarrow e^{+}\gamma^{*} e^{-} \rightarrow e^{+} Z\, Z\, e^{-}$ and $e^{+}e^{-} \rightarrow e^{+}\gamma^{
