Knowledge, Attitudes, and Practices of Dental Students on Pulp Sensitivity Tests and Diagnostic Tools

open access: yesJournal of Dental Education, EarlyView.
ABSTRACT Objective To investigate the knowledge of Brazilian dental students about pulp sensitivity tests (PSTs), their attitudes concerning their aptitude for performing different diagnostic tools (DTs), and how frequently these DTs are practiced in clinical scenarios involving asymptomatic teeth.

Dynamic range of hypercubic stochastic excitable media [PDF]

open access: yes, 2008
We study the response properties of d-dimensional hypercubic excitable networks to a stochastic stimulus. Each site, modelled either by a three-state stochastic susceptible-infected-recovered-susceptible system or by the probabilistic Greenberg-Hastings ...

A DUF3455 domain‐containing protein promotes Ustilaginoidea virens infection and functions as a plant immune elicitor

open access: yesNew Plant Protection, EarlyView.
The fungal effector UvDUF1 from Ustilaginoidea virens not only promotes infection but also acts as a plant immunity elicitor, inducing broad‐spectrum disease resistance in rice and Nicotiana benthamiana. These results reveal its potential as a novel target for sustainable crop protection strategies.

Mechanical alloying of Cu and Fe induced by severe plastic deformation of a Cu-Fe composite

open access: yes, 2005
A filamentary composite elaborated by cold drawing was processed by High Pressure Torsion (HPT). The nanostructure resulting from this severe plastic deformation (SPD) was investigated thanks to scanning electron microscopy, transmission electron ...

Strategy for One‐Step Optimization of Metal Oxide Passivating Contact Materials for Si Heterojunction Solar Cells through Growth Angle Variation

open access: yesSmall, EarlyView.
A one‐step oblique angle reactive sputtering approach enables simultaneous tuning of bulk and interfacial stoichiometry in a metal oxide/ silicon heterojunction. In case of vanadium oxides, growth angle variation controls the formation of stoichiometric SiO2, ternary SiOx(V) interlayer, and phase purity of vanadium oxide, considerably simplifying the ...

Green Fluorescent Protein (GFP) in Vector Systems Played Sense Role of Epigenetic in Plants [PDF]

open access: yes, 2008
The green fluorescent protein (GFP) of jellyfish (_Aequorea victoria_) has significant advantages over other reporter genes, because expression can be detected in living cells without any substrates.

Cell‐in‐Bead‐in‐Droplet Platform for pH‐Based Microfluidic Screening of Ureolytic Bacteria

open access: yesSmall, EarlyView.
Efficient high‐throughput microbial screening in droplet microfluidics is often challenged by chemical crosstalk between droplets. This is particularly difficult in pH‐changing biological processes, for which more effective biochemical assays are needed.
