Height, weight, and body mass index trajectories and their correlation with functional outcome assessments in boys with Duchenne muscular dystrophy

open access: yesDevelopmental Medicine &Child Neurology, EarlyView.
The analysis of height, weight, and BMI z‐score trajectories in boys with DMD from the FOR‐DMD study showed that higher baseline height was associated with slower subsequent growth, and older age with greater weight gain after glucocorticoid initiation.

A study on W9-curvature tensor within the framework of Lorentzian para-Sasakian manifold

open access: yesExtracta Mathematicae
This article focuses on the study of Lorentzian para-Sasakian manifolds Mn . It demonstrates that a W9-semisymmetric Lorentzian para-Sasakian manifold is a W9-flat manifold.

Conformal invariance of (0, 2) sigma models on Calabi-Yau manifolds

open access: yesJournal of High Energy Physics, 2018
Long ago, Nemeschansky and Sen demonstrated that the Ricci-flat metric on a Calabi-Yau manifold could be corrected, order by order in perturbation theory, to produce a conformally invariant (2, 2) nonlinear sigma model.

Long way to Ricci flatness

open access: yesJournal of High Energy Physics, 2020
We study two-dimensional weighted N $$ \mathcal{N} $$ = (2) supersymmetric ℂℙ models with the goal of exploring their infrared (IR) limit. 𝕎ℂℙ(N, N ˜ $$ \tilde{N} $$ ) are simplified versions of world-sheet theories on non-Abelian strings in four ...

Ricci-flat manifolds of generalized ALG asymptotics

open access: yes, 2022
In complex dimensions $\geq 3$, we provide a geometric existence for generalized ALG complete non-compact Ricci flat Kähler manifolds with Schwartz decay i.e. metric decay in any polynomial rate to an ALG model $\mathbb{C}\times Y$ modulo finite cyclic group action, where $Y$ is Calabi-Yau.

ESG Thematic Bonds in Emerging Markets: Risk, Uncertainty, and Ambiguity

open access: yesEuropean Financial Management, EarlyView.
ABSTRACT We examine the impact of risk aversion, ambiguity, and uncertainty (geopolitical and economic) on the ESG thematic bond markets in emerging countries. We analyze ESG sovereign (both USD and local currency denominated) and corporate bond markets on the aggregate and regional levels.

On M-theory fourfold vacua with higher curvature terms

open access: yesPhysics Letters B, 2015
We study solutions to the eleven-dimensional supergravity action, including terms quartic and cubic in the Riemann curvature, that admit an eight-dimensional compact space.

Towards a Geometrization of Renormalization Group Histories in Asymptotic Safety

open access: yesUniverse, 2021
Considering the scale-dependent effective spacetimes implied by the functional renormalization group in d-dimensional quantum Einstein gravity, we discuss the representation of entire evolution histories by means of a single, (d+1)-dimensional manifold ...

Active Transport of Carbon to Demersal Fish Communities in Shelf‐Slope‐Abyssal Systems of the North Atlantic Ocean

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract The biological carbon pump sequesters carbon through passive fluxes of biologically derived carbon, and by active vertical movement of marine organisms. Trophic coupling between pelagic and benthic communities increases the efficiency of the biological carbon pump as less carbon is lost to remineralization.
