Unveiling Global Diversity of Patescibacteriota and Functional Interactions with Host Microbes

open access: yesAdvanced Science, EarlyView.
Patescibacteriota represents a diverse group of ultra‐small epibiotic bacteria, which is largely overlooked. By integrating ribosomal protein S3‐based community profiling with MAG‐based metabolic potential analyses, this study provides new insights into their distribution, diversity, and potential interactions with other bacteria across diverse ...

Symmetric Markov Chains

open access: yesThe Annals of Probability, 1974
W. Feller's decomposition into a road map and speed measure are adapted to symmetric Markov chains with instantaneous states. The road map is a family of matrices defined by time changing the process with measures concentrated on finite sets.

The Tumor‐to‐Endothelial Transfer of FTO Promotes Vascular Remodeling and Metastasis in Nasopharyngeal Carcinoma

open access: yesAdvanced Science, EarlyView.
Integrated omics analysis of matched primary and liver metastatic NPC tumors reveals a unique NOTCH1+ CSC subpopulation exhibiting enhanced stemness properties and tumorigenic capacity. With in vitro and in vivo assays, exosomal transfer of tumor‐derived FTO from NOTCH1+ cells to the endothelium promotes vascular permeability and metastatic potential ...

Two Novel S‐methyltransferases Confer Dimethylsulfide Production in Actinomycetota

open access: yesAdvanced Science, EarlyView.
This study identifies two novel S‐adenosine‐methionine‐dependent methyltransferases, MddM1 and MddM2, in actinomycetes from the Mariana Trench. These enzymes can convert toxic hydrogen sulfide (H2S) and methanethiol (MeSH) into dimethylsulfide (DMS), serving as a cellular detoxification and oxidative stress response.

Dissipative control of a three-species food chain stochastic system with a hidden Markov chain

open access: yesAdvances in Difference Equations, 2017
This paper focuses on a three-species food chain system which is formulated as stochastic differential equations with regime switching represented by a hidden Markov chain. Firstly, using the Wonham filter, we estimate the hidden Markov chain through the

Temporal Transcriptional Regulation of Human Neuronal Differentiation via Forward Programming

open access: yesAdvanced Science, EarlyView.
Single‐cell profiling of TF‐induced forward programming versus stepwise dual‐SMAD differentiation reveals that divergent trajectories set the pace of neurogenesis. OLIG TFs advance cell‐cycle exit via NOTCH modulation, while NEUROD2 later accelerates maturation. The study elucidates transcriptional mechanisms governing differentiation timing, providing

Applying diffusion-based Markov chain Monte Carlo. [PDF]

open access: yesPLoS ONE, 2017
We examine the performance of a strategy for Markov chain Monte Carlo (MCMC) developed by simulating a discrete approximation to a stochastic differential equation (SDE). We refer to the approach as diffusion MCMC.

Explicit Compression Degradation Estimations for Low‐Sampling Single‐Pixel Imaging using Hadamard Basis

open access: yesAdvanced Science, EarlyView.
This study proposes a degradation estimation technique to explicitly describe compressive sampling for low‐sampling Hadamard single‐pixel imaging. Blur kernels in explicit degradation models are estimated by the self‐supervised learning method without labeled data and implicit priors.

Strong Ergodicity in Nonhomogeneous Markov Systems with Chronological Order

open access: yesMathematics
In the present, we study the problem of strong ergodicity in nonhomogeneous Markov systems. In the first basic theorem, we relax the fundamental assumption present in all studies of asymptotic behavior.

Stochastic Methods for Analysis of Complex Hardware-Software Systems

open access: yesТруды Института системного программирования РАН, 2018
In this paper we consider Markov analysis of models of complex software and hardware systems. A Markov analysis tool can be used during verification processes of models of avionics systems.
