Prenatal betamethasone–postnatal N‐methyl‐D‐aspartic acid model of spasms: Update on mechanisms and treatments

open access: yesEpilepsia Open, EarlyView.
Abstract Infantile epilepsy spasms syndrome (IESS), formerly known as infantile spasms or West Syndrome, is a severe epilepsy syndrome affecting about 3 in 10,000 newborns in the United States. Characterized by clusters of epileptic spasms, interictal hypsarrhythmia, and developmental delays, IESS has diverse causes, including structural‐metabolic ...

Fukaya categories of surfaces, spherical objects and mapping class groups

open access: yesForum of Mathematics, Sigma, 2021
We prove that every spherical object in the derived Fukaya category of a closed surface of genus at least $2$ whose Chern character represents a nonzero Hochschild homology class is quasi-isomorphic to a simple closed curve equipped with a rank $1 ...

Ricci iteration for coupled K\"ahler-Einstein metrics

open access: yes, 2019
In this paper, we introduce the "coupled Ricci iteration", a dynamical system related to the Ricci operator and twisted K\"ahler-Einstein metrics as an approach to the study of coupled K\"ahler-Einstein (CKE) metrics.

A version of smooth K-theory adapted to the total Chern class [PDF]

open access: yes, 2008
A version of smooth K-theory is constructed, which is adapted to the total Chern class instead of the Chern character (contrarily to previous theories).

Investigation of Social Media Metrics With Respect to Demand Modeling for Promotional Products

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT Social media (SM) has revolutionized the way companies connect with customers, enabling more personalized marketing strategies and enhancing engagement. With platforms like Facebook offering detailed user data, businesses can create more targeted advertising campaigns. This paper proposes an approach to categorizing SM variables based on their

Higher dimensional quantum Hall effect as A-class topological insulator

open access: yesNuclear Physics B, 2014
We perform a detail study of higher dimensional quantum Hall effects and A-class topological insulators with emphasis on their relations to non-commutative geometry.

Holographic spin liquids and Lovelock Chern-Simons gravity

open access: yesJournal of High Energy Physics, 2020
We explore the role of torsion as source of spin current in strongly interacting conformal fluids using holography. We establish the constitutive relations of the basic hydrodynamic variables, the energy-momentum tensor and the spin current based on the ...

Anisotropic Kondo line defect and ODE/IM correspondence

open access: yesSciPost Physics, 2023
We study the anisotropic Kondo line defects in products of chiral SU(2) WZW models. We propose an ODE/IM correspondence for the anisotropic Kondo problems by considering the four-dimensional Chern Simons theory in the trigonometric case.

An almost-integral universal Vassiliev invariant of knots

open access: yes, 2002
A `total Chern class' invariant of knots is defined. This is a universal Vassiliev invariant which is integral `on the level of Lie algebras' but it is not expressible as an integer sum of diagrams.
