Ordered extreme ranked set sampling and its application in parametric estimation [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2016
Ranked set sampling (RSS) is applicable whenever ranking of a set of sampling units can be done easily by a judgment method or based on the measurement of an auxiliary variable which can be measured easily.

Concomitants of Order Statistics and Record Values from Generalization of FGM Bivariate-Generalized Exponential Distribution

open access: yesJournal of Statistical Theory and Applications (JSTA), 2019
We introduce the generalized Farlie–Gumbel–Morgenstern (FGM) type bivariate-generalized exponential distribution. Some distributional properties of concomitants of order statistics as well as record values for this family are studied.

An inertial forward–backward algorithm for the minimization of the sum of two nonconvex functions

open access: yesEURO Journal on Computational Optimization, 2016
We propose a forward–backward proximal-type algorithm with inertial/memory effects for minimizing the sum of a nonsmooth function with a smooth one in the nonconvex setting.

Symplectic Radon Transform and the Metaplectic Representation

open access: yesEntropy, 2022
We study the symplectic Radon transform from the point of view of the metaplectic representation of the symplectic group and its action on the Lagrangian Grassmannian.

Coping With Production Risk: Effects of Sown Plant Diversity on the Attractiveness of Crop Insurance in Grasslands

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Increased frequency of extreme weather events, particularly droughts, threatens grassland farming by destabilizing yields and farms' economic viability. We examine, theoretically and through numerical simulations, how sown plant diversity (natural insurance) influences the attractiveness of indemnity and drought index insurance (formal ...

Full-Endoscopic Anterior Cervical Decompression and Fusion for Cervical Myelopathy [PDF]

open access: yesNeurospine
This article aims to introduce a novel full-endoscopic anterior cervical discectomy and fusion (ACDF) procedure to treat cervical myelopathy. Adoption of endoscopic anterior cervical procedures has been lagging due to safety concerns and the necessity of

Too Complex to Choose? The Role of Heuristics in Shaping Farmers' Willingness to Pay for Income Stabilization Tool in Italy

open access: yesAgribusiness, EarlyView.
ABSTRACT European agriculture is increasingly exposed to economic instability driven by extreme weather events, market volatility, and geopolitical tensions. To manage these growing risks, farmers are encouraged to adopt innovative risk management strategies such as the Income Stabilization Tool (IST), which offers protection against severe income ...

Asymptotic arbitrage in fractional mixed markets

open access: yesModern Stochastics: Theory and Applications, 2018
We consider a family of mixed processes given as the sum of a fractional Brownian motion with Hurst parameter $H\in (3/4,1)$ and a multiple of an independent standard Brownian motion, the family being indexed by the scaling factor in front of the ...

Expanding the Utility of Exome Sequencing in Preventive and Population Genetics

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Carrier screening is a long‐standing genetic testing process offered to at‐risk couples, with or without a family history, who might have pregnancies affected by an autosomal recessive (AR) or X‐linked (XL) disorder. A total of 276 unrelated individuals, initially referred for rare disorder screening by clinicians, were enrolled in this study ...
