Passive Directional Water Transport on Superhydrophobic Gradient Textures Fabricated by Direct Laser Interference Patterning

open access: yesAdvanced Materials Technologies, EarlyView.
Microstructures fabricated by two‐beam DLIP combining spatial‐period and roughness gradients are fabricated to enhance directional transport of water droplets. The coupled gradients increase transport distance by 160% and strongly suppress motion against the gradient, demonstrating an effective strategy for controlled droplet manipulation.

A stochastic SEIR model with Holling type II treatment and Ornstein–Uhlenbeck process

open access: yesKuwait Journal of Science
This paper investigates a stochastic SEIR epidemic model that incorporates both Holling type II treatment and an Ornstein-Uhlenbeck process (OUP). By constructing appropriate non-negative Lyapunov functions, we establish the existence and uniqueness of a

Are Per Capita Real GDP Series in African Countries Non-stationary or Non-linear? What does Empirical Evidence Reveal? [PDF]

open access: yes
This paper extends the applied time series literature in economic development, by testing whether the per capita real GDP time series in 27 African countries are non-stationary or non-linear and globally stationary over the relatively long period from ...

Collagen‐Based Gut‐on‐Chip for In Vitro Modeling of Intestinal Barrier Function and Host‐Pathogen Interactions

open access: yesAdvanced Materials Technologies, EarlyView.
A collagen‐based gut‐on‐chip model replicates the intestinal extracellular matrix, supporting villi‐like structures, tight junctions, and mucin production. This biomimetic platform enables rapid epithelial differentiation and functional barrier formation.

Programmable Pneumatic Actuator System for a Bioinspired Artificial Colon

open access: yesAdvanced Materials Technologies, EarlyView.
A modular soft robotic colon simulator driven by programmable pneumatic actuation is developed to mimic physiological and pathological‐like motility patterns of the large intestine. Finite element–guided design and distributed control enable anatomically realistic deformation for peristalsis, segmentation, and mass movements, supporting capsule ...

Modelling Income Using the Generalised Lambda Distribution

open access: yes, 2008
In the present article we propose the generalised lambda distribution as a model for income data. The quantile measures of location, dispersion, skewness, and kurtosis of the distribution are matched against the corresponding measures derived from the ...

Multilayer Biobased Poly(ethylene furanoate)/Graphene Oxide Nanofibrous Membranes With Directional Water Transport for Efficient Microplastics Filtration

open access: yesAdvanced Materials Technologies, EarlyView.
A self‐assembled multilayer biobased PEF/GO nanofibrous membrane was developed by electrospinning for efficient PLA microplastics (MPs) filtration. The membrane combines superhydrophilicity, directional water transport, mechanical robustness, and a synergistic size‐exclusion interception and electrostatic repulsion MPs separation mechanism, enabling ...

The Beaman Distribution: A New Descriptive Model for the Size Distribution of Incomes

open access: yes, 2008
A new two-parameter descriptive model for the size distribution of incomes is presented. The Beaman distribution, originally found to describe the relationship between prices and sales volumes of textiles and related products, is shown to fit closely US ...
