On the dynamics of skew tent maps
, 2017 In this paper we give an elementary treatment of the dynamics of skew tent maps. We divide the two-parameter space into six regions. Two of these regions are further subdivided into infinitely many regions. All of the regions are given explicitly. We find the attractor in each subregion, determine whether the attractor is a periodic orbit or is chaotic,

Advanced Science, EarlyView.scTIDE identifies single‐cell tipping points by combining manifold‐based graph representations with optimal‐transport conditional flow matching, which preserves intrinsic topology and models distributional dynamics. It supports critical‐transition detection at individual‐cell resolution, prediction of unseen cells, and dimensionality reduction and ...

Advanced Science, EarlyView.In MYC‐enforced B‐cell lymphoma, SOX5 occupies promoter‐proximal regulatory regions and is associated with reduced chromatin accessibility at the PCNP locus. PCNP repression promotes proliferative remodeling by limiting apoptosis and cell‐cycle restraint.

Closure measures for coarse-graining of the tent map
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2014 We quantify the relationship between the dynamics of a time-discrete dynamical system, the tent map T and its iterations Tm, and the induced dynamics at a symbolical level in information theoretical terms. The symbol dynamics, given by a binary string s of length m, is obtained by choosing a partition point α∈[0,1] and lumping together the points x∈[0 ...

Therapeutic Gene Editing of APOE4 in Sporadic Alzheimer's Disease via Prime Editor 7
Advanced Science, EarlyView.Prime Editor 7‐mediated conversion of APOE4 to APOE3 alleviates Alzheimer's disease‐associated pathology in AD mouse models and patient‐derived neurons and improves cognitive performance in vivo, supporting therapeutic genome editing as a promising strategy for APOE4‐associated neurodegeneration.

A novel image encryption/decryption scheme based on integrating multiple chaotic maps
AIP Advances, 2020 In this paper, a novel framework is presented for chaotic image encryption. The proposed method is based on integrating multiple chaotic maps (e.g., logistic, tent, quadratic, cubic, and Bernoulli) to generate more robust chaotic maps in order to ...

Advanced Science, EarlyView.ADORA2A activation suppresses NFκB‐dependent CCL5 production in cNK cells during chronic HBV infection, disrupting intrahepatic DC recruitment and HBV‐specific CD8+ T‐cell differentiation and function. Targeting the ADORA2A/NFκB/CCL5 axis restores antiviral immunity and facilitates HBV clearance.

MathematicsChaotic maps are sources of randomness formed by a set of rules and chaotic variables. They have been incorporated into metaheuristics because they improve the balance of exploration and exploitation, and with this, they allow one to obtain better ...

Transposable Element–Driven PIEZO Mutation Enhances Locust Flight in Plateau Hypoxia
Advanced Science, EarlyView.Why transposable elements (TEs) persisted or expanded in genomes remains a mystery. Using integrated analysis of TE macro‐ and microevolution in locusts, our results showed that thousands of TE insertions promoted widespread adaptive variation. Subfamilies of candidate adaptive TEs amplified and reshaped species‐level genomic architecture.
