How Do Weak, Misaligned Tropical Cyclones Evolve Toward Alignment? A Multi‐Case Study Using the Hurricane Analysis and Forecast System

open access: yesJournal of Geophysical Research: Atmospheres, Volume 127, Issue 20, 27 October 2022., 2022
Abstract This study simulates five initially weak, moderately sheared tropical cyclones (TCs) from the 2020–2021 North Atlantic basin hurricane seasons using the Hurricane Analysis and Forecast System (HAFS). Four of the five simulations rapidly evolve from misaligned vortices with asymmetric precipitation and thermodynamic distributions toward more ...

Universal prediction band via semi‐definite programming

open access: yesJournal of the Royal Statistical Society: Series B (Statistical Methodology), Volume 84, Issue 4, Page 1558-1580, September 2022., 2022
Abstract We propose a computationally efficient method to construct nonparametric, heteroscedastic prediction bands for uncertainty quantification, with or without any user‐specified predictive model. Our approach provides an alternative to the now‐standard conformal prediction for uncertainty quantification, with novel theoretical insights and ...

The Many Chemists Who Could Have Proposed the Woodward‐Hoffmann Rules But Didn't: The Organic Chemists Who Discovered the Smoking Guns[]**

open access: yesThe Chemical Record, Volume 22, Issue 6, June 2022., 2022
Emanuel Vogel, Rudolf Criegee, and William G. Dauben were three of the organic chemists in whose laboratories some of the earliest experimental hints were observed for the mechanism of the no‐mechanism reaction. Abstract It is a reasonable question to ask, why, as of 1965 when the five Woodward‐Hoffmann communications appeared, did no other organic ...

Privacy‐preserving quality control of neuroimaging datasets in federated environments

open access: yesHuman Brain Mapping, Volume 43, Issue 7, Page 2289-2310, May 2022., 2022
Privacy concerns for rare disease data, institutional or IRB policies, access to local computational or storage resources or download capabilities are among the reasons that may preclude analyses that pool data to a single site. A growing number of multi‐site projects and consortia were formed to function in the federated environment to conduct ...

Isoperimetric and Functional Inequalities

open access: yesМоделирование и анализ информационных систем, 2018
We establish lower estimates for an integral functional$$\int\limits_\Omega f(u(x), \nabla u(x)) \, dx ,$$where \(\Omega\) -- a bounded domain in \(\mathbb{R}^n \; (n \geqslant 2)\), an integrand \(f(t,p) \, (t \in [0, \infty),\; p \in \mathbb{R}^n)\) --

An application of the continuous Steiner symmetrization to Blaschke-Santaló diagrams [PDF]

open access: yesESAIM: Control, Optimisation and Calculus of Variations, 2021
In this paper we consider the so-called procedure ofContinuous Steiner Symmetrization, introduced by Brock in [F. Brock,Math. Nachr.172(1995) 25–48 and F. Brock,Proc. Indian Acad. Sci.110(2000) 157–204]. It transforms every open set Ω ⊂⊂ ℝdinto the ball keeping the volume fixed and letting the first eigenvalue and the torsional rigidity respectively ...

Convergence properties of symmetrization processes [PDF]

open access: yes, 2022
Steiner symmetrization is well known for its rounding and general convergence properties. We identify a whole family of symmetrizations sharing analogue behaviors: In fact we prove that all these symmetrizations share the same converging symmetrization ...

Affine inequalities for L p $L_{p}$ -mixed mean zonoids

open access: yesJournal of Inequalities and Applications, 2016
In this paper, we introduce the L p $L_{p}$ -mixed mean zonoid of convex bodies K and L, and we prove some important properties for the L p $L_{p}$ -mixed mean zonoid, such as monotonicity, GL ( n ) $\operatorname{GL}(n)$ covariance, and so on.
