Generalized 2D polynomial chaotic map and its application in information transmission

open access: yesTongxin xuebao, 2022
Existing chaotic systems have many defects in engineering applications, such as discontinuous chaotic parameter range, weak chaos, uneven output of chaotic sequences and dynamic degradation.Therefore, a generalized 2D polynomial chaotic mapping model was

Multiple-Image Encryption Scheme Based on an N-Dimensional Chaotic Modular Model and Overlapping Block Permutation–Diffusion Using Newly Defined Operation

open access: yesMathematics, 2023
Some existing chaotic maps have the drawbacks of a narrow range of chaotic parameters and discontinuities, which may be inherited by new chaotic systems generated from them as seed maps.

A Plug‐and‐Play Volume Minimizing Micromixer

open access: yesAdvanced Science, EarlyView.
ABSTRACT Microscale fluid mixing has numerous applications where rapid and efficient mixing is required, including drug discovery, bio‐analysis and point‐of‐care diagnostics. Conventional soft lithography processes, however, make the integration of robust and reliable mixing difficult to implement in practice, especially across different flow rates ...

Capture and Culture of Circulating Tumor Cells Using a Biodegradable 3D Scaffold for Patient‐Derived Xenograft Construction

open access: yesAdvanced Science, EarlyView.
A self‐supporting, biocompatible, and biodegradable 3D cellulose scaffold has been developed for efficient isolation and in situ expansion of circulating tumor cells (CTCs) from patient blood. Subsequently, the 3D cellulose scaffold with cultured CTCs is directly implanted into immunodeficient mice for constructing patient CTC‐derived xenograft (CDX ...

Selective Targeting of Tip Endothelial Cells as a Therapeutic Strategy for Tumor Angiogenesis

open access: yesAdvanced Science, EarlyView.
Doppel protein is selectively expressed in tip endothelial cells within the tumor vasculature, where it promotes tip cell motility and stabilizes the tip cell phenotype. Targeting Doppel with monoclonal antibodies disrupts this stabilization, impairs angiogenic sprouting, and reduces tumor angiogenesis, offering a selective and druggable switch for ...

Cuckoo Search Algorithm with Chaotic Maps [PDF]

open access: yesMathematical Problems in Engineering, 2015
Cuckoo search algorithm is a novel nature-inspired optimization technique based on the obligate brood parasitic behavior of some cuckoo species. It iteratively employs Lévy flights random walk with a scaling factor and biased/selective random walk with a fraction probability.

AI‐Enhanced Vibrational Capsule for Minimally Invasive Detection of Abnormal Bowel Tissue

open access: yesAdvanced Science, EarlyView.
A fully integrated vibration‐assisted capsule is presented for the minimally invasive detection of bowel lesions. The capsule incorporates a wireless sensor and an eccentric motor to probe tissue mechanics in situ. By coupling triaxial vibration signals with AI‐based classification and analytical modeling, the system enables early, non‐visual ...

Chaos analysis of viscoelastic chaotic flows of polymeric fluids in a micro-channel

open access: yesAIP Advances, 2015
Many fluids, including biological fluids such as mucus and blood, are viscoelastic. Through the introduction of chaotic flows in a micro-channel and the construction of maps of characteristic chaos parameters, differences in viscoelastic properties of ...

Universal Antibody‐Engineered Lipid Nanoparticles Potentiate Chemo‐Immunotherapy Against Triple‐Negative Breast Cancer by Reprogramming Tumor Cell Metabolism

open access: yesAdvanced Science, EarlyView.
A universal ROR1 antibody‐engineered lipid nanoparticle (LNP) is constructed by sequential drug encapsulation and antibody conjugation. The LNP not only enables enhanced chemotherapeutic efficiency by targeting drug delivery and precise localization of deep‐seated tumors through NIR‐II fluorescence imaging, but also remodels immunosuppressive TME ...

Encoding Cumulation to Learn Perturbative Nonlinear Oscillatory Dynamics

open access: yesAdvanced Science, EarlyView.
Weak nonlinearities critically shape the long term behavior of oscillatory systems but are difficult to identify from data. A data‐driven framework is introduced to infer governing equations of weakly nonlinear oscillators from sparse and noisy observations.
