Cell-Cell Signaling Proteobacterial LuxR Solos: a Treasure Trove of Subgroups Having Different Origins, Ligands, and Ecological Roles [PDF]

open access: yesMSystems, 2023
Many proteobacteria possess LuxR solos which are quorum sensing LuxR-type regulators that are not paired with a cognate LuxI-type synthase. LuxR solos have been implicated in intraspecies, interspecies, and interkingdom communication by sensing ...

LuxR Solos from Environmental Fluorescent Pseudomonads [PDF]

open access: yesMSphere, 2021
Cell-cell communication in bacteria is being extensively studied in simple settings and uses chemical signals and cognate regulators/receptors. Many Gram-negative proteobacteria use acyl-homoserine lactones (AHLs) synthesized by LuxI family proteins and ...

Artificial neural networks applied for soil class prediction in mountainous landscape of the Serra do Mar¹ [PDF]

open access: yesRevista Brasileira de Ciência do Solo, 2014
Soil information is needed for managing the agricultural environment. The aim of this study was to apply artificial neural networks (ANNs) for the prediction of soil classes using orbital remote sensing products, terrain attributes derived from a digital

MORFOMETRIA DE BACIAS HIDROGRÁFICAS DE PRIMEIRA ORDEM EM ÁREAS AGRÍCOLAS SOB SISTEMA PLANTIO DIRETO: DELIMITAÇÃO E PROPENSÃO À EROSÃO E INUNDAÇÃO

open access: yesRevista Brasileira de Geomorfologia, 2020
O Sistema Plantio Direto (SPD) aplica técnicas agrícolas conservacionistas para preservação do solo, controlando processos de erosão. Para isso, é necessário conhecer as características do relevo que afetam a dinâmica e o poder erosivo da água na ...

Acyclic Solos and Differential Interaction Nets [PDF]

open access: yes, 2010
We present a restriction of the solos calculus which is stable under reduction and expressive enough to contain an encoding of the pi-calculus. As a consequence, it is shown that equalizing names that are already equal is not required by the encoding of ...
