Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS 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

REGULARITY AND NUMERICAL SOLUTION FOR THE EXACT CONTROL

open access: yesPesquimat, 2014
In this paper we study a Numerical Method based on Finite Difference to the Boundary Exact Controllability problem for the Wave Equation. We consider the one dimensional problem.

Exact boundary controllability of 3-D Euler equation [PDF]

open access: yesESAIM: Control, Optimisation and Calculus of Variations, 2000
Let \(\Omega\) be a 3-dimensional domain with boundary \(\Gamma,\) \(\Gamma_0 \subseteq \Gamma,\) \(y_0, y_T\) vector fields with \(\nabla \cdot y_0 = \nabla \cdot y_T = 0\) in \(\Omega\) and \(y_0 \cdot n = y_T \cdot n = 0\) on \(\Gamma \setminus \Gamma_0\) (\(n\) the outer normal vector). The problem is to construct a solution of \[ \partial_t y + (y

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 ...

Partial exact controllability for the linear thermo-viscoelastic model

open access: yesElectronic Journal of Differential Equations, 1998
The problem of partial exact controllability for linear thermo-viscoelasticity is considered. Using classical multiplier techniques, a boundary observability inequality is established under smallness restrictions on coupling parameters and relaxation ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Exact controllability for a semilinear wave equation with both interior and boundary controls

open access: yesAbstract and Applied Analysis, 2005
The exact controllability of a semilinear wave equation in a bounded open domain of Rn, with controls on a part of the boundary and in the interior, is shown. Feedback laws are established.

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.

Exact controllability for a string equation in domains with moving boundary in one dimension

open access: yesElectronic Journal of Differential Equations, 2015
We consider a string equation in a domain with moving boundary. By using the multiplier method in non-cylindrical domains, we establish the exact boundary controllability in domains with moving boundary, and obtain a weaker condition on the time ...
