Advanced Engineering Materials, EarlyView.A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

DYNAMIC INPUT DEMAND FUNCTIONS AND RESOURCE ADJUSTMENT FOR U.S. AGRICULTURE: STATE EVIDENCE [PDF]
The paper presents an econometric model of dynamic agricultural input demand functions that includes research based technical change and autoregressive disturbances and fits the model to data for a set of state aggregates pooled over 1950-82.

Advanced Engineering Materials, EarlyView.This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Purchasing Power Parity and the Real Exchange Rate in Bangladesh: A Nonlinear Analysis [PDF]
The long-run purchasing power parity (PPP) hypothesis is examined using data for Bangladesh and its major trading partners - the US, Euro area, Japan and India - during the period 1994 to 2002. We apply recently developed nonlinear econometric techniques

A Practical Noise2Noise Denoising Pipeline for High‐Throughput Raman Spectroscopy
Advanced Engineering Materials, EarlyView.A lightweight and reproducible denoising pipeline for high‐throughput Raman spectroscopy is introduced, based on a 1D convolutional autoencoder trained with a Noise2Noise strategy. Using only repeated short‐exposure acquisitions, the method suppresses stochastic noise without reference spectra, enabling reliable spectral reconstruction while preserving

NON-LINEAR ADJUSTMENT PROCESS IN WON/DOLLAR AND WON/YEN REAL EXCHAGE RATES [PDF]
We examine the purchasing power parity (PPP) hypothesis in won/dollar and won/yen real exchange rates using a non-linear framework. Many empirical studies based on the linear framework have failed to find clear supporting evidence for the validity of PPP
