Polarisation of night-time ELF–VLF atmospherics as statistically approached [PDF]

open access: yesРадиофизика и электроника, 2019
Subject and Purpose. Tweek-atmospherics (night-time low-frequency atmospherics), along with radio transmission by VLF radio stations, are used to study the lower ionosphere. The predictions of the available analytical theory regarding the polarization of

Past participle agreement in Abruzzese: split auxiliary selection and the null-subject parameter [PDF]

open access: yesNatural Language & Linguistic Theory, 2010
In this paper, we present an analysis of the “person-driven” auxiliary-selection system of one variety of the Upper Southern Italo-Romance dialect Abruzzese, along with an account of the pattern of past participle agreement in this variety, which differs somewhat from what is found in more familiar Romance languages. Our account relies on the technical

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

open access: yesAdvanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Operational modal analysis with uncertainty quantification for SDDLV-based damage localization

open access: yesMATEC Web of Conferences, 2015
The Stochastic Dynamic Damage Locating Vector (SDDLV) approach is a vibration-based damage localization method based on a finite element model of a structure in a reference state and output-only measurements in both reference and damaged states. A stress

Generalized dilatation operator method for non-relativistic holography

open access: yesPhysics Letters B, 2014
We present a general algorithm for constructing the holographic dictionary for Lifshitz and hyperscaling violating Lifshitz backgrounds for any value of the dynamical exponent z and any value of the hyperscaling violation parameter θ compatible with the ...

On the Impact Energy Absorption of an Advanced High‐Strength Bilayer Steel Composite Consisting of Carbide‐Free Bainitic Steel and High‐Mn Twinning‐Induced Plasticity Steel

open access: yesAdvanced Engineering Materials, EarlyView.
Excellent combinations of strength and impact toughness are obtained in a bilayer composite of high‐strength carbide‐free bainitic (CFB) steel and high‐ductility twinning‐induced plasticity (TWIP) steel. The composite absorbs energy at small strains when the notch is placed on the TWIP side and at high strains when the notch is placed on the CFB side ...

On the uniqueness of the Myers-Perry spacetime as a type II(D) solution in six dimensions

open access: yesJournal of High Energy Physics, 2017
We study the class of vacuum (Ricci flat) six-dimensional spacetimes admitting a non-degenerate multiple Weyl aligned null direction ℓ, thus being of Weyl type II or more special. Subject to an additional assumption on the asymptotic fall-off of the Weyl
