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 ...

Resource Allocation and Minmax Scheduling Under Group Technology and Different Due-Window Assignments

open access: yesAxioms
This article investigates single-machine group scheduling integrated with resource allocation under different due-window (DIFDW) assignment. Three distinct scenarios are examined: one with constant processing times, one with a linear resource consumption

Generation, Ranking and Unranking of Ordered Trees with Degree Bounds [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2016
We study the problem of generating, ranking and unranking of unlabeled ordered trees whose nodes have maximum degree of Δ. This class of trees represents a generalization of chemical trees. A chemical tree is an unlabeled tree in which no node has degree

Nearly-Linear Time Algorithms for Preconditioning and Solving Symmetric, Diagonally Dominant Linear Systems [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, 2006
We present a randomized algorithm that on input a symmetric, weakly diagonally dominant $n$-by-$n$ matrix $A$ with $m$ nonzero entries and an $n$-vector $b$ produces an ${\tilde{x}} $ such that $\|{\tilde{x}} - A^{\dagger} {b} \|_{A} \leq \epsilon \|A ...

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

A Comparison between Standard and Functional Clustering Methodologies: Application to Agricultural Fields for Yield Pattern Assessment

open access: yesRemote Sensing, 2018
The recognition of spatial patterns within agricultural fields, presenting similar yield potential areas, stable through time, is very important for optimizing agricultural practices.

Inserting Multiple Edges into a Planar Graph

open access: yesJournal of Graph Algorithms and Applications, 2023
Let $G$ be a connected planar (but not yet embedded) graph and $F$ a set of edges with ends in $V(G)$ and not belonging to $E(G)$. The multiple edge insertion problem (MEI) asks for a drawing of $G+F$ with the minimum number of pairwise edge crossings,

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

open access: yesFEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...
