The spread of new viral pathogens and phytoplasmas in cultivated plants and their risks

open access: yesFood Risk Assess Europe, Volume 4, Issue 1, January 2026.
Abstract The study contains a description of the genome and particles, spectrum of host plants, geographical distribution, forecast of spread and impacts on agricultural production, disease symptoms, life cycle, and means of protection in integrated and organic production in the Czech Republic for 22 plant viruses, 3 viroids and 4 phytoplasmas, in ...

Controllable Entanglement of Lights in a Five-Level System

open access: yes, 2005
We analyze the nonlinear optical response of a five-level system under a novel configuration of electro-magnetically induced transparency. We show that a giant Kerr nonlinearity with a relatively large cross-phase modulation coefficient that occurs in ...

Deletion Mutants of VPg Reveal New Cytopathology Determinants in a Picornavirus

open access: yesPLoS ONE, 2010
Success of a viral infection requires that each infected cell delivers a sufficient number of infectious particles to allow new rounds of infection. In picornaviruses, viral replication is initiated by the viral polymerase and a viral-coded protein, termed VPg, that primes RNA synthesis.

Parity transitions in the superconducting ground state of hybrid InSb-Al Coulomb islands

open access: yes, 2018
The number of electrons in small metallic or semiconducting islands is quantized. When tunnelling is enabled via opaque barriers this number can change by an integer.

Long-term photometric behaviour of XZ Dra Binarity or magnetic cycle of a Blazhko type RRab star

open access: yes, 2002
The extended photometry available for XZ Dra, a Blazhko type RR Lyrae star, makes it possible to study its long-term behavior. It is shown that its pulsation period exhibit cyclic, but not strictly regular variations with approx. 7200 d period.

Coulomb oscillations in three-layer graphene nanostructures

open access: yes, 2008
We present transport measurements on a tunable three-layer graphene single electron transistor (SET). The device consists of an etched three-layer graphene flake with two narrow constrictions separating the island from source and drain contacts.
