The Dielectrophoretic Interactions of Curved Particles in a DC Electric Field [PDF]

open access: yesMicromachines
In practical dielectrophoretic cell interaction experiments, cells do not always exhibit circular or rod-like shapes, making the study of dielectrophoretic interactions among irregularly shaped particles of significant importance.

A curved compliant spinal bone anchor to enhance fixation strength. [PDF]

open access: yesPLoS ONE
Pedicle screws have long been established as the gold standard for spinal bone fixation. However, their fixation strength can be compromised in cases of low bone density, particularly in osteoporotic bone, due to the reliance on a micro-shape lock ...

Natural and forsed osculations of pipelines in contact with the Wincler medium [PDF]

open access: yesE3S Web of Conferences, 2023
In this paper, the pipeline is modeled as a curved rod in contact with the Winkler medium. Linear oscillations of a curved viscoelastic rod lying on the Winkler base are considered.

Statics and dynamics of curved rods based on Bernoulli hypotheses and relations for a rectilinear rod

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2023
Method for calculating the statics and dynamics of curved rods, based on the equations for a rectilinear rod, is described and justified in detail. Bernoulli's hypotheses and the variational method are applied.

Improving the Efficiency of Curved Wells’ Operation by Means of Progressive Cavity Pumps

open access: yesEnergies, 2022
This paper proposes a solution to the problem of improving the reliability of the operation of progressive cavity pump units in deviated and directional wells. High dogleg severity significantly contributes to rod breakage; rods often break close to the “

Asymmetric peptidoglycan editing generates cell curvature in Bdellovibrio predatory bacteria

open access: yesNature Communications, 2022
Cells of the predatory bacterium Bdellovibrio bacteriovorus, which invades and replicates within the periplasm of other bacteria, have a characteristic curved rod shape. Here, Banks et al.
