Encountering Huberia

open access: yesJournal for the History of Knowledge, 2023
This article implicates the question of what a scholar is with the question of when a scholar is: that is, how a scholar is positioned in time. The act of such positioning—“timing”—involves a wide array of negotiations: it embraces everything from the ...

The effects of contracting Covid-19 on cognitive failures at work: implications for task performance and turnover intentions

open access: yesScientific Reports, 2022
Individuals who contract Covid-19 often experience problems with memory, attention, and concentration, even after recovering from the initial illness. In the current manuscript, we argue that these symptoms are likely to manifest as cognitive failures in

Stream lamination and rapid mixing in a microfluidic jet for X-ray spectroscopy studies

open access: yesFlow, 2023
Microfluidic mixers offer new possibilities for the study of fast reaction kinetics down to the microsecond time scale, and methods such as soft X-ray absorption spectroscopy are powerful analysis techniques.

Is a baseball like knuckleball possible in cricket?

open access: yesFlow, 2023
The knuckleball is considered to be one of the hardest pitches to hit in baseball due to its seemingly unpredictable motion. It has gained popularity in cricket in recent times.

Acoustofluidic semen analysis for veterinary male bovine infertility assessment

open access: yesFlow, 2023
We demonstrate through the use of a unique acoustically driven microfluidic extensional rheometry platform (ADMiER) that a single measurement – i.e. the time required for a liquid bridge filament comprising a microlitre semen sample to thin and break up ...

Wind speed inference from environmental flow–structure interactions

open access: yesFlow, 2021
This study aims to leverage the relationship between fluid dynamic loading and resulting structural deformation to infer the incident flow speed from measurements of time-dependent structure kinematics.

Large eddy simulation of aircraft at affordable cost: a milestone in computational fluid dynamics

open access: yesFlow, 2021
While there have been numerous applications of large eddy simulations (LES) to complex flows, their application to practical engineering configurations, such as full aircraft models, have been limited to date.

Drop-on-demand painting of highly viscous liquids

open access: yesFlow, 2021
An on-demand painting system with a simple structure device that ejects highly viscous liquids as microjets is introduced. An impulsive motion of the container results in the ejection of a viscous liquid jet from the nozzle.

Design waves and statistics of linear gap resonances in random seas

open access: yesFlow, 2021
Water wave resonance between two side-by-side vessels is a multimode resonant hydrodynamic phenomenon with low damping. The potential flow damping and viscous damping inside the gap play a significant role, influencing the amplitudes of the gap ...

Effects of prey capture on the swimming and feeding performance of choanoflagellates

open access: yesFlow, 2023
Locomoting organisms often carry loads such as captured prey or young. Load-carrying effects on high-Reynolds-number flight have been studied, but the fluid dynamics of load carrying by low-Reynolds-number microorganisms has not.
