Reconstructing Old Chinese *‐ts Using Han‐Time Material

Transactions of the Philological Society, EarlyView.
Abstract Baxter & Sagart (2014b) reconstruct *‐Vt‐s on the basis of Middle Chinese reflexes in ‐jH (from some OC *‐s) coupled with either etymological or graphic connections to words in Middle Chinese ‐t. This approach, while perfectly sound, can suffer from lack of etymological or graphic data, leading to missed reconstructions. Since Old Chinese *‐ts

Least-Squares Collocation for Higher-Index Linear Differential-Algebraic Equations : Estimating the Instability Threshold

, 2019
Differential-algebraic equations with higher-index give rise to essentially ill-posed problems. The overdetermined least-squares collocation for differential-algebraic equations which has been proposed recently is not much more computationally expensive ...

Heterogeneous Spillover Effects: How FDI in Resources Extraction, Manufacturing, and Services Affect Sectoral Carbon Emissions in the MENA Region

Natural Resources Forum, EarlyView.
ABSTRACT The MENA region faces a critical challenge: balancing economic growth spurred by foreign direct investment (FDI) with environmental sustainability. While FDI can bring technological advancements and capital, concerns exist about its potential to exacerbate environmental degradation, particularly carbon emissions.

Mass and momentum conservation of the least-squares spectral collocation method for the Navier–Stokes equations

, 2011
From the literature, it is known that the Least-Squares Spectral Element Method (LSSEM) for the stationary Stokes equations performs poorly with respect to mass conservation but compensates this lack by a superior conservation of momentum.

Greek ΜΝΗΣΘΗ and Aramaic DKYR in the Near East: A Comparative Epigraphic Study

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Past studies of graffiti containing the word ΜΝΗΣΘΗ have never fully established its intrinsic meaning. However, due to the existence of the Aramaic term DKYR, which carries a seemingly identical meaning to ΜΝΗΣΘΗ, in similar contexts in the Roman Near East, a comparison between both words is possible. Four distinct sites where the coexistence

A Christoffel function weighted least squares algorithm for collocation approximations

Mathematics of Computation, 2016
We propose, theoretically investigate, and numerically validate an algorithm for the Monte Carlo solution of least-squares polynomial approximation problems in a collocation framework. Our investigation is motivated by applications in the collocation approximation of parametric functions, which frequently entails construction of surrogates via ...

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

The regression model of virtual GPS reference station by application of collocation method

Geodesy and Cartography, 2012
The principle of calculating coordinates determined by GPS method and carrier's phase shift and corrections for pseudoranges as well as applying the regression models created by method of collocation is presented in the article.

Hierarchical Differentiable Fluid Simulation

Computer Graphics Forum, EarlyView.
We introduce a two‐step algorithm that significantly reduces memory usage for solving control problems using differentiable fluid simulation techniques: our method first optimizes for bulk forces at reduced resolution, then refines local details over sub‐domains while maintaining differentiability. In trading runtime for memory, it enables optimization
