Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The role of endogenous salicylic acid (SA) signalling cascades in plant responses to salt and oxidative stresses is unclear. Arabidopsis SA signalling mutants, namely npr1-5 (non-expresser of pathogenesis related gene1), which lacks NPR1-dependent SA signa ...
Communication between vascular smooth muscle cells (SMCs) allows control of their contraction and so regulation of blood flow. The contractile state of SMCs is regulated by cytosolic Ca2+ concentration (Ca2+) which propagates as Ca2+ waves over a sign ...
Communication between vascular smooth muscle cells (SMCs) allows control of their contraction and so regulation of blood flow. The contractile state of SMCs is controled by cytosolic Ca2+ concentration ([Ca2+]i) which propagates as Ca2+ waves over a signif ...
The 5-hydroxytryptamine 3 receptor (5-HT3R) is a member of the pentameric ligand-gated ion channel (pLGIC) family, that plays an important role in fast signal transduction and cell-cell communication in synapses: They convert a chemical signal from a neuro ...
In transport experiments, the quantum nature of matter becomes directly evident when changes in conductance occur only in discrete steps1, with a size determined solely by Planck's constant h. Observations of quantized steps in electrical conductance2,3 ha ...
Action Potential (APs) patterns of sensory cortex neurons encode a variety of stimulus features, but how can a neuron change the feature to which it responds? Here, we show that in vivo a spike-timing-dependent plasticity (STDP) protocol-consisting of pair ...
We present here Al2O3/W hetero-structured nanopore membranes which function as native and electrical field tunable nanofluidic diodes. A typical membrane is 100×100 μm2 in size with pore density of ∼ 20/μm2. The nanopores are 26 nm in diameter and 400 nm i ...
Spectral induced polarization is receiving increasing attention as a tool to map subsurface properties in a non-invasive manner. Although empirical correlations have been devised to link measurements to porous medium properties, such as the time constant o ...
In this paper, we present an analytical semiempirical model of the profile of the channel charge and potential in quasi-ballistic double-gate (DG) MOSFETs. The charge model is based on the premise of separating the charge density in the quasi-ballistic cha ...
The scaling of device technologies poses new challenges, not only in circuit design, but also in device modeling, especially because of the short-channel effects and the emergence of novel phenomena like ballistic transport. Nonetheless, it enables the des ...
