On Filter Convergence, Ideal Convergence, Seminorm Kernel Convergence and Statistical Measure Convergence of Sequences [PDF]

open access: yes, 2012
从1951年Fast引入统计收敛的定义之后,统计收敛得到了许多数学家的深入探讨和研究。经过这半个多世纪的发展,统计收敛已经成为一个庞大的理论体系,各种各样的统计收敛多达几十种。从2008年到2011年程立新等建立的统计收敛的测度理论使得各种各样的统计收敛在其定义的统计测度意义下得到统一。 本文就是在统计收敛的测度理论基础上,进一步研究滤子收敛,理想收敛。我们首先介绍半范收敛以及统计测度收敛的概念,证明了滤子收敛,理想收敛,半范kernel收敛,统计测度收敛这四种收敛他们之间具有某种等价性 ...

Designable van der Waals Crystal for Artificial Neuronal Cell Mimicking

open access: yesAdvanced Materials, EarlyView.
Designable van der Waals crystal has been demonstrated for device‐scale neuronal cell mimicking. The structural similarity between ion‐channel in biological membranes and layered vdW lattices is realized with nano‐crystallization via Ar + H2S plasma sulfurization.

A Dual‐Bioresponsive and Programmable Microneedle Matrix as a Bioinspired Coupler for Orchestrating Diabetic Bone Regeneration

open access: yesAdvanced Materials, EarlyView.
This project developed a smart bandage‐like patch (a microneedle array) for repairing diabetic bone damage. It intelligently senses signals from infection and inflammation, then releases its medicines in a specific, timed sequence: first an antibacterial agent, then an anti‐inflammatory agent, and finally growth factors.

Statistical convergent functions via ideals with respect to the intuitionistic fuzzy 2-normed spaces

open access: yes, 2019
The main objective of this paper is to introduce and studythe notion of ideal Lamda-statistical convergence of a nonnegative real-valuedLebesque measurable function in the interval (1,infinity) with respect to theintuitionistic fuzzy 2-normed (Mü, vi) , investigate their relationship, and make some observationsabout these classes.

Femtosecond‐Laser Mould Texturing Enables Tunable Biointerfaces in COC Microfluidics

open access: yesAdvanced Materials Interfaces, EarlyView.
Femtosecond‐laser texturing of injection‐mould inserts enables scalable engineering of biointerfaces in cyclic olefin copolymer microfluidics. Replicated micro‐ and nano‐topographies modulate surface roughness and wettability, leading to texture‐dependent protein adsorption and cell adhesion without chemical post‐processing.

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Characterization of Droplet Formation in Ultrasonic Spray Coating: Influence of Ink Formulation Using Phase Doppler Anemometry and Machine Learning

open access: yesAdvanced Materials Technologies, EarlyView.
This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control
