Mycobacterium tuberculosis Requires Phosphate-Responsive Gene Regulation To Resist Host Immunity

Mycobacterium tuberculosis persists in the tissues of mammalian hosts despite inducing a robust immune response dominated by the macrophage-activating cytokine gamma interferon (IFN-gamma). We identified the M. tuberculosis phosphate-specific transport (Ps ...

Collaborative Control for a Robotic Wheelchair: Evaluation of Performance, Attention and Workload

Tom Edward Carlson

Powered wheelchair users often struggle to drive safely and effectively and in more critical cases can only get around when accompanied by an assistant. To address these issues, we propose a collaborative control mechanism that assists the user as and when ...

Power and pin efficient chip-to-chip communications with common-mode rejection and sso resilience

Mohammad Amin Shokrollahi, Harm Cronie

In bus communications methods and apparatus, a first set of physical signals representing the information to be conveyed over the bus is provided, and mapped to a codeword of a spherical code, wherein a codeword is representable as a vector of a plurality ...

Time-Dependent Approach for Single Trial Classification of Covert Visuospatial Attention

José del Rocio Millán Ruiz, Robert Leeb, Luca Tonin

Recently, several studies have started to explore covert visuospatial attention as a control signal for brain–computer interfaces (BCIs). Covert visuospatial attention represents the ability to change the focus of attention from one point in the space with ...

Theoretical Study of High Repetition Rate Short Pulse Generation With Fiber Optical Parametric Amplification

In this paper, we study theoretically the generation of high repetition rate short pulses using fiber optical parametric amplification. We show that the pulse shape and duration depend on the signal location relatively to the pump frequency. We demonstrate ...

Electromechanical Coupling In Cardiac Dynamics: The Active Strain Approach

Alfio Quarteroni, Fabio Nobile

The coupling between cardiac mechanics and electric signaling is addressed in a nonstandard framework in which the electrical potential dictates the active strain (not stress) of the muscle. The physiological and mathematical motivations leading us to this ...

Orthogonal differential vector signaling

Mohammad Amin Shokrollahi, Harm Cronie

Using a transformation based at least in part on a non-simple orthogonal or unitary matrix, data may be transmitted over a data bus in a manner that is resilient to one or more types of signal noise, that does not require a common reference at the transmis ...

Cognitive Radio Through Primary Control Feedback

Michael Christoph Gastpar

A fundamental problem in dynamic frequency reuse is that the cognitive radio is ignorant of the amount of interference it inflicts on the primary license holder. Policies that attempt to limit interference without the active participation of the primary ar ...

Continuous-wave four-wave mixing in cm-long Chalcogenide microstructured fiber

Camille Sophie Brès

We present the experimental demonstration of broadband four-wave mixing in a 2.5 cm-long segment of AsSe Chalcogenide microstructured fiber. The parametric mixing was driven by a continuous-wave pump compatible with data signal wavelength conversion. Four- ...

Observing Thermobifida fusca cellulase binding to pretreated wood particles using time-lapse confocal laser scanning microscopy

Jeremy Luterbacher

We report on studies of Thermobifida fusca cellulases Cel5A, Cel6B and Cel9A binding to pretreated wood particles using Confocal Laser Scanning Microscopy (CLSM). Hydro-thermal pretreated wood particles were immobilized on borosilicate substrates before fl ...

Graph Chatbot

Chattez avec Graph Search

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.
