APPLICATION OF RULED SURFACES IN FREEFORM AND GEAR METROLOGY

Acta Polytechnica, 2021
An application of two ruled surfaces (i.e., surfaces generated by a motion of a straight line), a surface of hyperbolic paraboloid and a tangent surface of a cylindrical helix in freeform and gear metrology is introduced in this paper. Both surfaces have

Holomorphic Foliations in Ruled Surfaces [PDF]

Transactions of the American Mathematical Society, 1989
We analyse the universal families of holomorphic foliations with singularities in a ruled surface. In terms of Chern classes we determine the general and the special families. We also classify all nonsingular foliations.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Deformations of ruled surfaces.

Journal für die reine und angewandte Mathematik (Crelles Journal), 1992
In spite of the long history of the theory of ruled surfaces, their deformations so far have only been studied for ruled surfaces with rational or elliptic base curves. In this paper, I deal with the versal deformation and the deformation types of arbitrary ruled surfaces over \(\mathbb{C}\).

Digital twins to accelerate target identification and drug development for immune‐mediated disorders

FEBS Open Bio, EarlyView.
Digital twins integrate patient‐derived molecular and clinical data into personalised computational models that simulate disease mechanisms. They enable rapid identification and validation of therapeutic targets, prediction of drug responses, and prioritisation of candidate interventions.

Ruled Surfaces in Elliptic Space [PDF]

Proceedings of the American Mathematical Society, 1970
Bonnet's theorem on ruled surfaces [2, p. 449] deals solely with intrinsic properties if an intrinsic definition of the line of striction is adopted. Contrasting this, our aim is to define the parameter of distribution and the line of striction in relation to the enveloping space and to show that they have the usual properties. Attention will be called

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

FEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Singular Miminal Ruled Surfaces

, 2023
In this paper we study surfaces with minimal potential energy under gravitational forces, called singular minimal surfaces. We prove that a singular minimal ruled surface in a Euclidean $3-$space is cylindrical, in particular as an $α-$catenary cylinder by a result of López [Ann. Glob. Anal. Geom. 53(4) (2018), 521-541]. This result is also extended in

Inhibition of Classical and Alternative Complement Pathway by Ravulizumab and Eculizumab

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To explore the feasibility of classical (CH50) and alternative (AH50) complement pathway activity as potential biomarkers for treatment guidance and monitoring during therapy with ravulizumab in patients with generalized myasthenia gravis (gMG) and compare these to therapeutic drug monitoring under eculizumab.

Characterization of the Evolute Offset of Ruled Surfaces with B-Darboux Frame

Journal of New Theory, 2020
In this paper, we first introduce the evolute offset of non-cylindricalruled surfaces with B-Darboux frame in Euclidean 3-space. Then some geometricproperties of this evolute offset of non-cylindrical ruled surface are studied.
