Markov Chain Approximations to Singular Stable-like Processes [PDF]
arXiv, 2012 We consider the Markov chain approximations for singular stable-like processes. First we obtain properties of some Markov chains. Then we construct the approximating Markov chains and give a necessary condition for weak convergence of these chains to singular stable-like processes.

Advanced Science, Volume 12, Issue 16, April 24, 2025.DPImpute is a two‐step pipeline that outperforms existing tools in whole‐genome SNP imputation, particularly under conditions of ultra‐low coverage sequencing, small sample sizes, and limited references. It enables precise imputation for single blastocyst cells, supporting genomic selection at the pre‐implantation stage.

Graphs: Associated Markov Chains [PDF]
arXiv, 2012 In this research paper, weighted / unweighted, directed / undirected graphs are associated with interesting Discrete Time Markov Chains (DTMCs) as well as Continuous Time Markov Chains (CTMCs). The equilibrium / transient behaviour of such Markov chains is studied.

Deterministic chaos for Markov chains [PDF]
arXiv, 2020 We find that Markov chains with finite state space are Poincare chaotic. Moreover, finite realizations of the chains are arcs of each unpredictable orbit for sure. An illustrating example with a proper numerical simulation is provided.

Design Principles From Natural Olfaction for Electronic Noses
Advanced Science, Volume 12, Issue 12, March 27, 2025.Unlocking “universal smell” requires integrating key principles of natural olfactory systems: modulation of gas transport, utilization of non‐selective sensing elements, chemical filters akin to the biological mucus layer to separate compounds, refined context‐specific signal integration, and more.

Regularity of harmonic functions for some Markov chains with unbounded range [PDF]
arXiv, 2012 We consider a class of continuous time Markov chains on $\Z^d$. These chains are the discrete space analogue of Markov processes with jumps. Under some conditions, we show that harmonic functions associated with these Markov chains are H\"{o}lder continuous.

Markov chains with replacement
Advances in Applied Probability, 1974 Abstract The following modification of a general state space discrete-time Markov chain is considered: certain transitions are supposed “forbidden” and the chain evolves until there is such a transition. At this instant the value of the chain is “replaced” according to a given rule, and, starting from the new value, the chain evolves normally until ...

CPL‐Diff: A Diffusion Model for De Novo Design of Functional Peptide Sequences with Fixed Length
Advanced Science, EarlyView.This study presents a diffusion model for generating functional peptide sequence lengths using mask control. The model can generate antimicrobial, antifungal, and antiviral peptides with specific lengths on demand. The model learns the structure of peptides better and generates peptides with better physicochemical properties, and the model has good ...
