Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Weak almost periodic and optimal mild solutions of fractional evolution equations
Electronic Journal of Differential Equations, 2009 In this article, we prove the existence of optimal mild solutions for linear fractional evolution equations with an analytic semigroup in a Banach space.

Expander Decomposition with Almost Optimal Overhead
CoRRWe present the first polynomial-time algorithm for computing a near-optimal \emph{flow}-expander decomposition. Given a graph $G$ and a parameter $ϕ$, our algorithm removes at most a $ϕ\log^{1+o(1)}n$ fraction of edges so that every remaining connected component is a $ϕ$-\emph{flow}-expander (a stronger guarantee than being a $ϕ$-\emph{cut}-expander ...

Robust Weighted Timed Automata and Games [PDF]
, 2013 Weighted timed automata extend timed automata with cost variables that can be used to model the evolution of various quantities. Although cost-optimal reachability is decidable (in polynomial space) on this model, it becomes undecidable on weighted ...

Almost supplementary difference sets and quaternary sequences with optimal autocorrelation [PDF]
, 2020 We introduce almost supplementary difference sets (ASDS). For odd m, certain ASDS in Zm that have amicable incidence matrices are equivalent to quaternary sequences of odd length m with optimal autocorrelation. As one consequence, if 2m − 1 is a prime

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Almost surely constrained convex optimization
, 2019 We propose a stochastic gradient framework for solving stochastic composite convex optimization problems with (possibly) infinite number of linear inclusion constraints that need to be satisfied almost surely. We use smoothing and homotopy techniques to handle constraints without the need for matrix-valued projections.
