On Gamelin constants [PDF]

open access: yesPacific Journal of Mathematics, 1984
The author proves that the corona theorem holds for finite bordered Riemann surfaces. He constructs a surface of infinite genus for which the corona theorem holds, and shows that this surface can be chosen to be of Parreau-Widom type or not.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Particularités de la reproduction des vaches allaitantes de races françaises

open access: yesINRAE Productions Animales, 2017
La reproduction des vaches allaitantes présente des particularités par rapport à celle des vaches laitières. Améliorer leur reproduction est un levier pour augmenter leur productivité.

Are rate constants constant?

open access: yesThe Journal of Physiology, 2006
In this issue of The Journal of Physiology, Uebachs et al. (2006) report a seemingly simple observation: the rate of recovery from inactivation of CaV3 (T-type) calcium channels depends on the length of the depolarization that produced the inactivation. Why is this heretical? A basic principle of chemical kinetics is that rate constants are constant.

Phosphoinositides and inositol phosphates as molecular glues

open access: yesFEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Malaria transmission in the coastal zone and in the Centre of Côte d’Ivoire during the dry season

open access: yesMalaria Journal
Background Malaria remains a threat in sub-Saharan Africa, particularly in Côte d'Ivoire, where it is endemic and represents the leading cause of hospital consultations, morbidity and mortality.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Varying constants

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2005
We review properties of theories for the variation of gravitation and fine structure ‘constants’. We highlight some general features of the cosmological models that exist in these theories with reference to recent quasar data that are consistent with time variation in the fine structure constant since a redshift of 3.5.

Is There a Cosmological Constant? [PDF]

open access: yesThe Astrophysical Journal, 1996
We present limits on the cosmological constant from the statistics of gravitational lenses using newly completed quasar surveys, new lens data, and a range of lens models. The formal limit is $λ_0 < 0.66$ at 95\% confidence in flat cosmologies, including the statistical uncertainties in the number of lenses, galaxies, quasars, and the parameters ...

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
