Phytoplasma infection in tomato is associated with re-organization of plasma membrane, ER stacks and actin filaments in sieve elements [PDF]

open access: yesFrontiers in Plant Science, 2015
Phytoplasmas, biotrophic wall-less prokaryotes, only reside in sieve elements of their host plants. The essentials of the intimate interaction between phytoplasmas and their hosts are poorly understood, which calls for research on potential ...

Sieve analysis using the number of infecting pathogens. [PDF]

open access: yesBiometrics, 2018
Summary Assessment of vaccine efficacy as a function of the similarity of the infecting pathogen to the vaccine is an important scientific goal. Characterization of pathogen strains for which vaccine efficacy is low can increase understanding of the vaccine's mechanism of action and offer targets for vaccine improvement.

Rigorous analysis of a randomised number field sieve [PDF]

open access: yesJournal of Number Theory, 2018
Factorisation of integers $n$ is of number theoretic and cryptographic significance. The Number Field Sieve (NFS) introduced circa 1990, is still the state of the art algorithm, but no rigorous proof that it halts or generates relationships is known. We propose and analyse an explicitly randomised variant.

Sieve analysis in HIV-1 vaccine efficacy trials. [PDF]

open access: yesCurr Opin HIV AIDS, 2013
The genetic characterization of HIV-1 breakthrough infections in vaccine and placebo recipients offers new ways to assess vaccine efficacy trials. Statistical and sequence analysis methods provide opportunities to mine the mechanisms behind the effect of an HIV vaccine.The release of results from two HIV-1 vaccine efficacy trials, Step/HVTN-502 (HIV ...

Development of Asbestos - Free Brake Pad Using Bagasse [PDF]

open access: yesTribology in Industry, 2010
Development of asbestos-free brake pad using bagasse was investigated with a view to replace the use of asbestos whose dust is carcinogenic. The bagasse were sieve into sieve grades of 100, 150, 250, 350 and 710µm.

The Influence of Silica Sand Granulometry and Sorting Level on Thermal Expansion [PDF]

open access: yesArchives of Foundry Engineering, 2023
The quality of the castings depends, among other influences, on the quality of the moulding mixture used. The silica sands used are characterized by high thermal expansion compared to other sands. The tendency to dilatation of the moulding mixture can be
