  • Percolation clusters are random fractals examined through probability distribution functions to understand their geometrical and transport properties.
  • Using renormalized field theory, researchers analyze the behavior of these distribution functions in varying scaling limits.
  • The study focuses on several aspects, such as pair-connection probability and self-avoiding walks, deriving results valid for any complexity of the perturbation theory.

Article Abstract

Percolation clusters are random fractals whose geometrical and transport properties can be characterized with the help of probability distribution functions. Using renormalized field theory, we determine the asymptotic form of various such distribution functions in the limits where certain scaling variables become small or large. Our study includes the pair-connection probability, the distributions of the fractal masses of the backbone, the red bonds, and the shortest, the longest, and the average self-avoiding walk between any two points on a cluster, as well as the distribution of the total resistance in the random resistor network. Our analysis draws solely on general, structural features of the underlying diagrammatic perturbation theory, and hence our main results are valid to arbitrary loop order.

Metal ions are indispensable to life, as they can serve as essential enzyme cofactors to drive fundamental biochemical reactions, yet paradoxically, excess is highly toxic. Higher-order cells have evolved functionally distinct organelles that separate and coordinate sophisticated biochemical processes to maintain cellular homeostasis upon metal ion stimuli. Here, we uncover the remodeling of subcellular architecture and organellar interactome in yeast initiated by several metal ion stimulations, relying on near-native three-dimensional imaging, cryo-soft X-ray tomography.

: This study explores how thoracic orientation affects lung pressure and injury outcomes from shock waves, building on earlier research that suggested human posture impacts injury severity. : A layered finite element model of the chest was constructed based on the Chinese Visual Human Dataset (CVH), including the rib and intercostal muscle layers. The dynamic response of the chest under 12 different angle-oriented shock waves under incident pressures of 200 kPa and 500 kPa was calculated.

Cerebral ischemic stroke, neuronal death, and inflammation bring difficulties in neuroprotection and rehabilitation. In this study, we developed and designed the ability of natural lactoferrin-polyethylene glycol-polyphenylalanine-baicalein nanomicelles (LF-PEG-PPhe-Bai) to target and reduce these pathological processes, such as neurological damage and cognitive impairment in the stages of poststroke. Nanomicelles made from biocompatible materials have improved bioavailability and targeted distribution to afflicted brain areas.

The local environment of the active site, such as the confinement of hydronium ions within zeolite pores, significantly influences catalytic turnover, similar to enzyme functionality. This study explores these effects in the hydrolysis of guaiacols─lignin-derived compounds─over zeolites in water. In addition to the interesting catechol products, this reaction is advantageous for study due to its bimolecular hydrolysis pathway, which involves a single energy barrier and no intermediates, simplifying kinetic studies and result interpretation.
