Le retour du lavaret : une action d'ingénierie écologique réussie à l'échelle d'un lac (Le Bourget)
Sciences, Eaux & Territoires, 2015 Les grands lacs alpins fournissent de nombreux services écosystémiques: supports, approvisionnement, régulation, culturels et récréatifs. Ils sont soumis à des pressions multiples, globales et locales, issues de leur bassin versant (flux de nutriments ...

Recent X-ray observations of intermediate BL Lac objects [PDF]
, 1998 We present recent ROSAT, ASCA and SAX observations of intermediate BL Lac objects (IBLs), i.e. BL Lacs which are located between high-energy and low-energy peaked BL Lac objects with respect to alpha_rx.

Advanced Functional Materials, EarlyView.Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Network Topology as a Driver of Bistability in the lac Operon
, 2008 The lac operon in Escherichia coli has been studied extensively and is one of the earliest gene systems found to undergo both positive and negative control. The lac operon is known to exhibit bistability, in the sense that the operon is either induced or

Detection of Protein–Protein Interactions in Escherichia coli With Single Molecule Sensitivity
Advanced Science, EarlyView.This article describes a regulatory circuit in Escherichia coli able to detect protein–protein interactions with exquisite sensitivity. The interaction between two hybrid proteins fused to Bordetella pertussis adenylate cyclase and its activator calmodulin triggers a potent cyclic AMP signaling cascade.

The Accretion Rates and Spectral Energy Distributions of BL Lacertae Objects
, 2002 We investigate the relationship between accretion rates and the spectral energy distributions (SEDs) of BL Lac objects, using a sample of objects for which published information on the host galaxies, emission-line luminosities, and peak frequencies and ...

Targeting Lactate and Lactylation in Cancer Metabolism and Immunotherapy
Advanced Science, EarlyView.Lactate, once deemed a metabolic waste, emerges as a central regulator of cancer progression. This review elucidates how lactate and its epigenetic derivative, protein lactylation, orchestrate tumor metabolism, immune suppression, and therapeutic resistance.
