Relaxation dynamics of generalized scale-free polymer networks
Scientific Reports, 2018 We focus on treelike generalized scale-free polymer networks, whose geometries depend on a parameter, γ, that controls their connectivity and on two modularity parameters: the minimum allowed degree, K min , and the maximum allowed degree, K max .

Novel Parallel Algorithms for Fast Multi-GPU-Based Generation of Massive Scale-Free Networks
Data Science and Engineering, 2019 A novel parallel algorithm is presented for generating random scale-free networks using the preferential attachment model. The algorithm, named cuPPA, is custom-designed for “single instruction multiple data (SIMD)” style of parallel processing supported

Robustness of Scale-Free Networks
, 2023 This dissertation provides a critical examination of the widely-held belief that scale-free networks, characterized by a power-law degree distribution, inherently possess a "robust-yet-fragile" nature. This notion suggests that when contrasted with random networks of the same size (i.e., having an identical number of vertices and edges), scale-free ...

On the controllability of clustered Scale-Free networks [PDF]
Journal of Complex Networks, 2019 In this paper, we compare the number of unmatched nodes and the size of dilations in two main random network models, the Scale-Free and Clustered Scale-Free networks. The number of unmatched nodes determines the necessary number of control inputs and is known to be a measure for network controllability, while the size of dilation is a measure of ...

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Large Communities in a Scale-Free Network [PDF]
Journal of Statistical Physics, 2016 We prove the existence of a large complete subgraph w.h.p. in a preferential attachment random graph process with an edge-step. That is, we prove that the random graph $G_{t}$ produced by the so-called GLP model at time $t$ contains a complete subgraph of order $t^α$, where $α= (1-\varepsilon)\frac{1-p}{2-p}$, $\varepsilon$ is any number such that ...

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.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
