Spontaneous decay rates in active waveguides [PDF]

open access: yes, 2005
We present a new method to measure the guided, radiated and total decay rates in one-dimensional waveguides. It is also theoretically shown that large modifications of the total decay rate can be achieved in realistic EDFAs and EDWAs with effective mode ...

Fabrication of Multifunctional FeSi Gyroid Lattice Composites via Additive Manufacturing and Polymer Infiltration

open access: yesAdvanced Engineering Materials, Volume 28, Issue 3, 4 February 2026.
A two‐step approach combining laser powder bed fusion of FeSi electrical steel with Bakelite infiltration enables the fabrication of multifunctional gyroid lattice composites. The resulting structures exhibit high strength, magnetic anisotropy, and complete polymer infiltration, demonstrating a simple and scalable route toward lightweight, mechanically

MLO and SBP genes from Theobroma cacao are differencially expressed between resistent and suscetible cacao plants infected with Moniliophthora perniciosa [PDF]

open access: yes, 2013
Among sequences previously identified as potentially envolved in the resistance versus susceptibility of Theobroma cacao to the fungus Moniliophthora perniciosa, the MLO (Mildew resistance lócus O) and the SBP (selenium binding protein) genes were found.

Systemic Effect of Ganoderma lucidum Filtrate on Septoria Leaf Spot and Pycnidia Formation by Septoria lycopersici

open access: yesJournal of Phytopathology, Volume 174, Issue 1, January/February 2026.
ABSTRACT This study aimed to evaluate the potential of the mycelial growth filtrate (MGF) from Ganoderma lucidum in providing systemic protection to tomato plants against Septoria lycopersici‐induced leaf spot and inhibiting the production of reproductive structures by the phytopathogen. In greenhouse experiments, foliar application of MGF at 40% (v/v)

Development of EST derived-SSRs of Theobroma grandiflorum for molecular breeding : S04P05 [PDF]

open access: yes, 2013
Simple sequence repeats (SSRs) markers are widely used in breeding programs, and SSRs associated to expressed sequence tags (ESTs) could be quite efficient in the selection of genotypes of interest.

Fungal Effectors in Biotrophic, Necrotrophic and Hemibiotrophic Pathosystems: A Systematic Review

open access: yesPlant Pathology, Volume 75, Issue 1, January/February 2026.
This study compares the mechanisms of action of effectors across different fungal lifestyles. Biotrophs secrete effectors that suppress plant defences, necrotrophs release effectors that induce cell death by activating defence responses, and hemibiotrophs combine both strategies.
