Understanding the Hygienic Behavioral Dynamics of Ants Using Multi‐State Models

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 4, Page 361-370, April 2026.
Leaf‐cutting ants adjust grooming to pathogen risk and vulnerable nestmates. Multi‐state Markov models reveal shorter, frequent self‐grooming bouts and reduced allogrooming persistence under stress, optimizing social immunity via stigmergic decision‐making.

Survivability model for reconfigurable service carrying network based on the stochastic Petri net

open access: yesTongxin xuebao, 2016
Aiming at the defect that the security attribute of RSCN couldn't be described with measurement,a survivabil-ity model for RSCN was proposed based on the stochastic Petri net.Firstly,a non-Markovian stochastic Petri net for RSCN was proposed,and then the

Flux Analysis in Process Models via Causality

open access: yes, 2010
We present an approach for flux analysis in process algebra models of biological systems. We perceive flux as the flow of resources in stochastic simulations. We resort to an established correspondence between event structures, a broadly recognised model

Interferon Regulatory Factor 2 (IRF2) Suppression Enhances Murine Cardiac Allograft Survival Through Immune Evasion

open access: yesImmunology, Volume 177, Issue 4, Page 752-765, April 2026.
Our data show that suppressing IRF2, genetically or by siRNA, modulates PD‐L1 and MHC‐I levels. This induced immune‐evasive state critically underlies the significantly prolonged survival of cardiac allografts, revealing a novel therapeutic avenue.

A Soft Microrobot for Single‐Cell Transport, Spheroid Assembly, and Dual‐Mode Drug Screening

open access: yesAdvanced Materials, Volume 38, Issue 18, 25 March 2026.
A soft, untethered hydrogel microrobot enables precise single‐cell delivery, self‐assembly into 3D spheroids, and real‐time thermal actuation. Driven by light‐induced convection and embedded with gold nanorods and temperature sensors, the microrobot guides cells, modulates local microenvironments, and supports drug testing.

Computational models for inferring biochemical networks [PDF]

open access: yes, 2014
Biochemical networks are of great practical importance. The interaction of biological compounds in cells has been enforced to a proper understanding by the numerous bioinformatics projects, which contributed to a vast amount of biological information ...

Single‐Cell Mitochondrial Lineage Tracing Decodes Fate Decision and Spatial Clonal Architecture in Human Hematopoietic Organoids

open access: yesAdvanced Science, Volume 13, Issue 17, 23 March 2026.
This study repurposes mitochondrial DNA mutations as endogenous barcodes for lineage tracing in human pluripotent stem cell‐derived organoids. Integrated with transcriptomic and spatial data, it reveals NOTCH‐mediated stromal‐progenitor crosstalk orchestrates clonal dynamics and spatial zonation during early hematopoietic development, offering a non ...

CSL model checking of Deterministic and Stochastic Petri Nets [PDF]

open access: yes, 2005
Deterministic and Stochastic Petri Nets (DSPNs) are a widely used high-level formalism for modeling discrete-event systems where events may occur either without consuming time, after a deterministic time, or after an exponentially distributed time.

Efficient Scheduling Algorithms for Multicore Cyclic Executives With Precedence and Exclusion Relations

open access: yesConcurrency and Computation: Practice and Experience, Volume 38, Issue 5, March 2026.
ABSTRACT Cyclic executives (CEs) offer the advantage of ensuring complete determinism with minimal runtime overhead, often making them the preferred choice for safety‐critical real‐time systems. However, generating CEs for multicore processors while addressing task precedence and exclusion relations presents significant challenges.
