A generalized wave action conservative equation for the dissipative dynamical system in the nearshore region [PDF]
, 2003 To describe the various complex mechanisms of the dissipative dynamical system between waves, currents, and bottoms in the nearshore region that induce typically the wave motion on large-scale variation of ambient currents, a generalized wave action ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome
FEBS Letters, EarlyView.This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Sensitivity for Set-Valued Discrete Dynamical Systems [PDF]
, 2016 Any discrete topological dynamical system can be extended to some hyper- space dynamical system. So the natural question to know if a property of the base system transfers on the extended one, and viceversa, arises.

FEBS Letters, EarlyView.The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Re-analyzing the dynamical stability of the HD 47366 planetary system [PDF]
, 2019 Multi-planet systems around evolved stars are of interest to trace the evolution of planetary systems into the post-main-sequence phase. HD 47366, an evolved intermediate-mass star, hosts two giant planets on moderately eccentric orbits.

Bifurcations in a Model of Criminal Organizations and a Corrupt Judiciary
EntropyLet a population be composed of members of a criminal organization and judges of the judicial system, in which the judges can be co-opted by this organization. In this article, a model written as a set of four nonlinear differential equations is proposed

FEBS 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 ...

Random Sampling of a Continuous-time [PDF]
, 2002 We consider a dynamical system where the state equation is given by a linear stochastic di#erential equation and noisy measurements occur at discrete times, in correspondence of the arrivals of a Poisson process.

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Arnol′d tongues arising from a grazing-sliding bifurcation [PDF]
, 2009 The Neımark–Sacker bifurcation, or Hopf bifurcation for maps, is a well-known bifurcation for smooth dynamical systems. At this bifurcation a periodic orbit loses stability, and, except at certain “strong” resonances, an invariant torus is born.
