A Computational Approach for Biomimetic Design of Liver‐On‐A‐Chip

Advanced Intelligent Discovery, EarlyView.
A biomimetic liver‐on‐a‐chip with antiparallel perfusion was designed using COMSOL‐guided simulation to replicate hepatic acinus transport. Full‐scale modelling revealed diffusion‐dominated, length‐dependent nutrient gradients and low‐shear conditions.

Influence of the Boundary Conditions on the Seismic Response of Existing Masonry Infills From In‐Plane and Dynamic Out‐of‐Plane Tests

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Despite increasing attention to the seismic performance of masonry infills, their out‐of‐plane dynamic behaviour remains insufficiently explored, particularly under pre‐existing in‐plane damage. This study presents a comprehensive experimental campaign designed to investigate the seismic behaviour of an existing weak masonry infill typology ...

Looking at Soil as It Is: Evolution of Microscopic Soil Characterization From Kubiëna to Artificial Intelligence

Journal of Plant Nutrition and Soil Science, EarlyView.
We provide a historic overview of microscopic soil structure characterization from its founding father, Walter Kubiëna, to several technical revolutions like automation, digitalization, and artificial intelligence. In addition to technical advancements, we explore how concepts and research questions have evolved in time.

Morphological characteristics and permeability evolution of deep mine gas drainage boreholes

Frontiers in Earth Science, 2022
Structural coal has low permeability and high gas content. The increase of mining depth seriously restricts the safe mining of deep mines. Hydraulic flushing is the main means of gas extraction.

Diffusion‐Limited Microfluidic Focusing: Oscillatory Electro‐Viscoelastic Migration of Nanoparticles and Extracellular Vesicles

Small, EarlyView.
Oscillatory electro‐viscoelastic migration (Osc‐EVM) achieves focusing of particles as small as 20 nm in a 50 µm × 50 µm channel. The colloidal sample experiences sustained electro‐viscoelastic lift over extended durations, effectively prolonging the channel length to infinity by periodically reversing the flow direction and electric field.

Press Hardening for Sustainable Lightweight Chassis Design in Heavy‐Duty Vehicles: A Material Performance and Life Cycle Assessment Approach

steel research international, EarlyView.
The article explores how high‐strength steels and press hardening revolutionize lightweight chassis design for heavy‐duty vehicles. It reveals that press hardened steels combined with shot peening can cut weight by up to 34% and reduce environmental impact by 21%–32%.

Experimental assessment of column rectangularity in flat‐slab slab–column connections

Structural Concrete, EarlyView.
Abstract This paper presents an experimental investigation of the punching shear behavior of seven 3.00 m × 3.00 m × 0.20 m flat slabs without shear reinforcement, supported by internal rectangular columns. The column side lengths were varied to obtain aspect ratios, cmax/cmin, from 1.67 to 4.00, while the flexural reinforcement and overall slab ...

The Coloniality of Data: Police Databases and the Rationalization of Surveillance from Colonial Vietnam to the Modern Carceral State

The British Journal of Sociology, EarlyView.
ABSTRACT Tracing the early adoption of computer gang databases by the Los Angeles County Sheriff's Department and the Los Angeles Police Department in the 1980s to the deployment of computationally‐assisted surveillance during the Vietnam War, this paper uses a genealogical approach to compare surveillance technologies developed across the arc of ...

Diversity and Plasticity of Hydraulic Traits Across a Relative Moisture Supply Gradient: Results From Multiple Common Gardens

Plant, Cell &Environment, EarlyView.
ABSTRACT Maintaining cellular hydration is essential for plant metabolic activity and carbon gain. Plants typically maintain hydration through efficiency of water transport networks, the ability to avoid network disruption, and retention of water via accumulation of osmotica. Given their global domain and their enduring presence across geological eras,
