Joint Detection of Structural Change and Nonstationarity in Autoregressions [PDF]

open access: yes
In this paper we develop a test of the joint null hypothesis of parameter stability and a unit root within an ADF style autoregressive specification whose entire parameter structure is potentially subject to a structural break at an unknown time period ...

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

Agreement and Null Subjects

open access: yesNordlyd, 2004
This paper argues that agreement is a theta-role bearer, either directly, when agreement is externally merged in a theta position, or indirectly, when it is internally merged, heading an argument chain. Like true clitics, agreement is either pronominal or anaphoric in nature, hence either locally free or locally bound. This distinction accounts for 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 ...

The Properties of Cointegration Tests in Models with Structural Change [PDF]

open access: yes
In this paper we examine, by means of Monte Carlo simulation, the properties of several cointegration tests when long run parameters are subject to structural changes.

Development and Preliminary In Vivo Study of 3D‐Printed Bioactive Glass Scaffolds with Trabecular Architecture

open access: yesAdvanced Engineering Materials, EarlyView.
This study reports the fabrication of trabecular bioactive glass scaffolds (composition “1d”: 46.1SiO2‐28.7CaO‐8.8MgO‐6.2P2O5‐5.7CaF2‐4.5Na2O wt%) through vat photopolymerization and the relevant results from mechanical testing and in vivo implantation procedures in rabbit femora, showing great promise for bone tissue engineering applications.

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

open access: yesAdvanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Information structure, subject positions, and the cartography of the preverbal field in Cibaeño Dominican Spanish

open access: yesIsogloss
Early generative studies on grammatical subjects produced two key findings: the Extended Projection Principle (Chomsky, 1982), and the Null Subject Parameter (NSP, e.g.

Referential Subject and Object Gaps in Modern Icelandic

open access: yesNordlyd: Tromsø University Working Papers on Language & Linguistics, 2004
This paper investigates the nature of subject and object gaps in coordinate structures in Modern Icelandic. Modern Icelandic is considered to be a semi-pro-drop language, since it generally licenses only generic null subjects; object gaps only occur in ...

Electrostatic Storage Ring [PDF]

open access: yes, 2012
In the trial \cite{BNL} of measuring the proton electric moment, storage rings with electrostatic lattice have been considered. Here an overview is given about the main parameters regarding such a kind of focusing.
