Weak Chaos in large conservative system -- Infinite-range coupled standard maps

, 2005
We study, through a new perspective, a globally coupled map system that essentially interpolates between simple discrete-time nonlinear dynamics and certain long-range many-body Hamiltonian models. In particular, we exhibit relevant similarities, namely (

How Salmonella Works Under Osmotic and Desiccation Stresses

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT Salmonella remains one of the leading threats in foods with reduced water activity, where it can survive for long periods and cause outbreaks. Its persistence stems from a wide array of adaptive strategies shaped by the selective pressures imposed by low‐moisture foods.

Pair quenched mean-field theory for the susceptible-infected-susceptible model on complex networks

, 2013
We present a quenched mean-field (QMF) theory for the dynamics of the susceptible-infected-susceptible (SIS) epidemic model on complex networks where dynamical correlations between connected vertices are taken into account by means of a pair ...

Advances in Wine Yeast Autolysis: Biochemical and Molecular Mechanisms, and the Release of Organic Compounds in White and Sparkling Wines—An Updated Review

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT Wine yeasts play a central role in alcoholic fermentation and significantly contribute to the sensory attributes of wines through cellular autolysis during lees aging (sur lie), especially in white wines. This process releases organic compounds that alter the wine's chemical and sensory profile.

Can Invasive Suckermouth Catfish, Hypostomus Plecostomus, Be Used as Fishmeal? A Potential Solution to Eradicate it from the Buriganga River, Bangladesh

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Can invasive suckermouth catfish, Hypostomus plecostomus, be used as fishmeal? A potential solution to eradicate it from the Buriganga River, Bangladesh ABSTRACT The sustainable replacement of conventional fish meal (CFM) remains a critical challenge for aquaculture, given its rising cost and limited supply.

Chaos in the thermodynamic limit

, 2000
We study chaos in the Hamiltonian Mean Field model (HMF), a system with many degrees of freedom in which $N$ classical rotators are fully coupled. We review the most important results on the dynamics and the thermodynamics of the HMF, and in particular ...

Unlocking the Synthetic Potential of HMF Derivatives in Catalytic Asymmetric Aza‐Piancatelli Rearrangement

ChemistryEurope, Volume 4, Issue 4, April 2026.
5‐Hydroxymethylfurfural (HMF) derivatives have been successfully transformed via asymmetric aza‐Piancatelli rearrangement catalyzed by a chiral phosphoric acid. This work constitutes the first example of asymmetric Piancatelli rearrangement on C‐5 substituted (2‐furyl)carbinols and its application to HMF derivatives, effectively unlocking the latent ...

Shifting baselines increase the risk of misinterpreting biodiversity trends

Ecography, Volume 2026, Issue 4, April 2026.
Ecological studies quantifying the impact of land‐use change on biodiversity may be sensitive to the choice of reference points – or baselines – particularly when sampling across human land‐use gradients and other space‐for‐time comparisons. Much depends on whether the chosen baseline has already undergone shifts in species composition because of ...
