Short Principal Ideal Problem in multicubic fields

open access: yesJournal of Mathematical Cryptology, 2020
One family of candidates to build a post-quantum cryptosystem upon relies on euclidean lattices. In order to make such cryptosystems more efficient, one can consider special lattices with an additional algebraic structure such as ideal lattices.

Retrospective Analysis of Meningioma and Alternative Method of Grading

open access: yesErciyes Medical Journal, 2020
Objective: The current classification of meningioma is based on the mitotic count, brain invasion and atypical histological changes. We re-evaluated the cases of meningioma to make accurate grading and to investigate the effects of morphological ...

Quick Overview of Face Swap Deep Fakes

open access: yesApplied Sciences, 2023
Deep Fake technology has developed rapidly in its generation and detection in recent years. Researchers in both fields are outpacing each other in their axes achievements. The works use, among other methods, autoencoders, generative adversarial networks,

Higher spins from exotic dualisations

open access: yesJournal of High Energy Physics, 2021
At the free level, a given massless field can be described by an infinite number of different potentials related to each other by dualities. In terms of Young tableaux, dualities replace any number of columns of height h i by columns of height D − 2 − h ...

WEIL NUMBERS GENERATED BY OTHER WEIL NUMBERS AND TORSION FIELDS OF ABELIAN VARIETIES [PDF]

open access: yesJournal of the London Mathematical Society, 2006
Using properties of the Frobenius eigenvalues, we show that, in a precise sense, ``most'' isomorphism classes of (principally polarized) simple abelian varieties over a finite field are characterized up to isogeny by the sequence of their division fields, and a similar result for ``most'' isogeny classes. Some global cases are also treated.

Bridging policies and practice: challenges and opportunities for the governance of disability and ageing

open access: yesInternational Journal of Integrated Care, 2010
Introduction: In the context of an increasingly ageing society with a growing number of persons diagnosed with chronic disabling conditions including dementia and persons with disabilities, ageing and disability represent two policy fields which need to ...

An Investigation into Sub-Critical Choke Flow Performance in High Rate Gas Condensate Wells

open access: yesEnergies, 2019
There have been some correlations in the literature to predict the gas and liquid flow rate through wellhead chokes under subcritical flow conditions. The majority of these empirical correlations have been developed based on limited production data sets ...

Improving the efficiency of using multivalued logic tools

open access: yesScientific Reports, 2023
Multivalued logics are becoming one of the most important tools of information technology. They are in great demand for creation of artificial intelligence systems that are close to human intelligence, since the functioning of the latter cannot be ...

Gaussian Fluctuation for the Number of Particles in Airy, Bessel, Sine, and Other Determinantal Random Point Fields [PDF]

open access: yesJournal of Statistical Physics, 2000
We prove the Central Limit Theorem for the number of eigenvalues near the spectrum edge for hermitian ensembles of random matrices. To derive our results, we use a general theorem, essentially due to Costin and Lebowitz, concerning the Gaussian fluctuation of the number of particles in random point fields with determinantal correlation functions.

Estimating neuronal connectivity from axonal and dendritic density fields

open access: yesFrontiers in Computational Neuroscience, 2013
Neurons innervate space by extending axonal and dendritic arborizations. When axons and dendrites come in close proximity of each other, synapses between neurons can be formed.
