Plasmon‐Induced Optothermal Manipulation of Colloidal Particles and Biological Entities Resilient to Saline Environments

open access: yesAdvanced Optical Materials, Volume 14, Issue 29, 7 August 2026.
The particle with high surface hydrophilicity exhibits strong thermophoretic attraction, as its dense hydration layer enhances the role of interfacial water molecules in determining thermophoretic mobility over other ionic effects. This finding elucidates the mechanism underlying the robust thermophoretic accumulation of Escherichia coli in high ...

Flow resistance parameterization for large wood in two‐dimensional depth‐averaged models: Effects of flow condition, blockage, and sediment

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Using 16 flume experiments and 2D modeling, we show that large‐wood flow resistance is not a fixed property of wood porosity but varies systematically with flow condition, blockage and most strongly sediment‐shaped bed topography. The drag coefficient and Manning's n are interchangeable, but calibration is essential where scour occurs.

Derivation of Predicted Pressure Drop Equation on Granular Particle Plug Transportation in Horizontal Pipe

open access: yesJournal of Fluid Science and Technology, 2008
In a plug transportation that is one of gas-solid two-phase flows, the prediction equations on particle velocity within a plug and pressure drop in a horizontal pipe have been formulated.

Integrated Hospital, Emergency Department, and Community Surveillance for Respiratory Viruses in Milan, Italy

open access: yesJournal of Medical Virology, Volume 98, Issue 8, August 2026.
ABSTRACT Respiratory virus circulation may vary across healthcare settings and age groups, potentially limiting the interpretability of surveillance based on a single source. In Milan, Italy, established community‐ and emergency department‐based systems coexist with hospital laboratory testing, but hospital ward‐level data are not routinely integrated.

Performance analysis of an undershot cross-flow water turbine based on the flow near the runner

open access: yesNihon Kikai Gakkai ronbunshu, 2016
Since the great east Japan earthquake in 2011, renewable energy is turned into importance. Hydro power is one of most important energies because it is not affected by weather condition and possible to generate steady quantity electric power, so it could ...

Aligning Real‐Time Recurrence Computational Fluid Dynamics Simulations with Plant Data for the Ruhrstahl–Heraeus Degassing Process of Steel

open access: yessteel research international, Volume 97, Issue 8, Page 4207-4222, August 2026.
Uncertainties exist in computational fluid dynamics (CFD) modeling of complex metallurgical processes, even when partly validated by laboratory experiments. rCFD enables computationally efficient prediction of long‐term RH degassing and can be adapted to vary flow conditions.

An analysis of the logistics performance index of EU countries with an integrated MCDM model

open access: yesEconomics and Business Review, 2019
Countries can check the performance of their logistics’ activities to determine their competitiveness in trade logistics. One way to check these performances is to analyze the country’s LPI value in detail which is released by the WB every two years ...

PIV in Practice

open access: yes, 2011
Experimental fluid mechanics has for a long time been used to visualize flow phenomenonqualitatively. Traditionally, visualization has been done with dye or tracer particle dueto their ability to follow the flow pattern well. One of the early pioneers in experimentalfluid mechanics was Ludwig Prandtl who used mica particles in water flumes to ...

Dynamic Evolution of Forearc Subsidence Controlled by Slab Geometry

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Several subduction zones worldwide present an enigmatic forearc topography and strain characterized by extension at a forearc ridge near the trench and shortening within a forearc valley located between the ridge and the magmatic arc. The development of this topography has been linked to progressive slab steepening, while strain patterns ...
