On the curvatures of the ruled surfaces of b-lift curves

Cumhuriyet Science Journal, 2021
In this study, we defined a new curve which is called the B-Lift curve, also obtained the Frenet vectors of the B-Lift curve. The ruled surfaces have been produced by taking base curves B-Lift curves.

INVESTIGATIONS OF SURFACES OF ATMOSPHERE LESS BODIES USING SCATTERED SOLAR LIGHT

Odessa Astronomical Publications, 2017
Sunlight scattered by surfaces of atmosphere less bodies carry information about details of these surfaces. Burns and Tedesco in 1979 published formula for estimations of dimensions of details located on surfaces of asteroids.

Polymer adsorption on curved surfaces [PDF]

Physical Review E, 2017
The conformational behavior of a coarse-grained finite polymer chain near an attractive spherical surface was investigated by means of multicanonical Monte Carlo computer simulations. In a detailed analysis of canonical equilibrium data over a wide range of sphere radius and temperature, we have constructed entire phase diagrams both for non-grafted ...

Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Differential Geometric Aspects of Pedal Curves on Surfaces

Journal of Mathematics
The purpose of this paper is to construct relations and characterizations between the pedal curves and surfaces and to find components of the vector of αt by the means of the pedal on the surface M.

Haptic identification of curved surfaces [PDF]

Perception & Psychophysics, 1994
In two experiments, the active haptic identification of three-dimensional mathematically well-defined objects is investigated. The objects, quadric surfaces, are defined in terms of the shape index, a quantity describing the shape, and curvedness, a quantity describing overall curvature.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

How gluon leading singularities discover curves on surfaces

Journal of High Energy Physics
We study the leading singularities for pure gluon amplitudes obtained by on-shell gluing of three-particle amplitudes for an arbitrary graph in any number of dimensions. By encoding the polarization vector contractions in a graphical way, on-shell gluing

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

FEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

Osculating Curves and Surfaces [PDF]

Transactions of the American Mathematical Society, 1926
The limit of a sequence of curves, each of which intersects a fixed curve in « +1 distinct points, which close down to a given point in the limit, is a curve having contact of the «th order with the fixed curve at the given point. If we substitute surface for curve in the above statement, the limiting surface need not osculate the fixed surface, no ...
