Inverted Sugar: Generalized Ray Tracing Algorithm [PDF]

open access: yes, 2014
Though particular algorithms utilizing Snell’s Law effectively describe most ray tracing, issues arise with infrasound applications, particularly in understanding waveguides.

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains

open access: yesFEBS Open Bio, EarlyView.
The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Micro Relation Decodes: Movement, Boundaries and Materiality in Drawing

open access: yesDiségno
This research explores how drawing and tracing have evolved into critical tools in scientific and political discourse. Tracing, once seen as mere reproduction, now involves transferring conditions, engaging with past events, and addressing urgent issues

Traces d'écriture, traces de pratiques, traces d'identités

open access: yes, 2009
Relationships between the concept of « trace » on the web and social exchange forms are more often thought as direct registration of social forms on the web. The idea of « trace » is here questionned from the mediation realized by websites, by involving, enlisting, incorporating traces of location, people, objects of the world.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

open access: yesFEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

NeuroEditor: a tool to edit and visualize neuronal morphologies

open access: yesFrontiers in Neuroanatomy
The digital extraction of detailed neuronal morphologies from microscopy data is an essential step in the study of neurons. Ever since Cajal’s work, the acquisition and analysis of neuron anatomy has yielded invaluable insight into the nervous system ...

La qualité différenciée de la viande bovine. La nécessaire stratégie d'innovation [PDF]

open access: yesBiotechnologie, Agronomie, Société et Environnement, 2003
Differentiation of beef meat by quality. The necessary strategy of innovation. The beef meat supply chain faces with a very delicate situation: on the long term, red meat consumption in the Western countries is declining to benefit of meats of ...

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

open access: yesFEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Lessons Learned From a Delayed‐Start Trial of Modafinil for Freezing of Gait in Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Freezing of gait (FOG) in people with Parkinson's disease (PwPD) is debilitating and has limited treatments. Modafinil modulates beta/gamma band activity in the pedunculopontine nucleus (PPN), like PPN deep brain stimulation. We therefore tested the hypothesis that Modafinil would improve FOG in PwPD.
