About an analogue of Neifeld’s connection on the space of centred planes with one-index basic-fibre forms

open access: yesДифференциальная геометрия многообразий фигур, 2019
This research is realized by Cartan — Laptev method (with prolongations and scopes, moving frame and exterior forms). In this paper we consider a space П of centered m-planes (a space of all centered planes of the dimension m).

Three-dimensional computed tomographic angular measurements of the canine tibia using a bone-centered coordinate system

open access: yesFrontiers in Veterinary Science, 2023
IntroductionCanine tibial alignment is determined by two-dimensional angular measurements, and tibial torsion is challenging. Aim of the study was the development and evaluation of a CT technique to measure canine tibial varus and torsion angles ...

Glued linear connection on surface of the projective space

open access: yesДифференциальная геометрия многообразий фигур, 2020
We consider a surface as a variety of centered planes in a multidi­mensional projective space. A fiber bundle of the linear coframes appears over this manifold. It is important to emphasize the fiber bundle is not the principal bundle.

Topological semimetals protected by off-centered symmetries in nonsymmorphic crystals [PDF]

open access: yes, 2016
Topological semimetals have energy bands near the Fermi energy sticking together at isolated points/lines/planes in the momentum space, which are often accompanied by stable surface states and intriguing bulk topological responses.

Modality-Independent Effect of Gravity in Shaping the Internal Representation of 3D Space for Visual and Haptic Object Perception

open access: yesJournal of Neuroscience, 2020
Visual and haptic perceptions of 3D shape are plagued by distortions, which are influenced by nonvisual factors, such as gravitational vestibular signals.

Kinetic Inductance Detectors and readout electronics for the OLIMPO experiment [PDF]

open access: yesJournal of Physics: Conference Series, 2019
Kinetic Inductance Detectors (KIDs) are superconductive low–temperature detectors useful for astrophysics and particle physics. We have developed arrays of lumped elements KIDs (LEKIDs) sensitive to microwave photons, optimized for the four horn–coupled ...

The Gromov width of complex Grassmannians [PDF]

open access: yes, 2005
We show that the Gromov width of the Grassmannian of complex k-planes in C^n is equal to one when the symplectic form is normalized so that it generates the integral cohomology in degree 2. We deduce the lower bound from more general results. For example,

The composition equipment for congruence of hypercentred planes

open access: yesДифференциальная геометрия многообразий фигур, 2019
In n-dimensional projective space Pn a manifold , i. e., a cong­ruence of hypercentered planes , is considered. By a hypercentered planе we mean m-dimensional plane with a (m – 1)-dimensional hy­perplane , distinguished in it.

Some Theorems for Feed Forward Neural Networks [PDF]

open access: yes, 2015
In this paper we introduce a new method which employs the concept of "Orientation Vectors" to train a feed forward neural network and suitable for problems where large dimensions are involved and the clusters are characteristically sparse. The new method
