Implementation of the spline method for mobile robot path control [PDF]
, 1999 This paper presents an implementation of a Spline Curve Algorithm in a mobile robot path-planning domain. This method is based on a continuous path mapped between two points. The path can easily be updated and modified as the robot moves.

Phase Diagrams and Piezoelectric Properties of Wurtzite Al1−x−yScxGdyN Heterostructural Alloys
Advanced Science, EarlyView.This study demonstrates ferroelectricity and piezoelectric properties improvement of quaternary wurtzite Al1−x−yScxGdyN${\rm Al}_{1-x-y}{\rm Sc}_x{\rm Gd}_y{\rm N}$ films, guided by density functional theory calculations. Wurtzite Al1−x−yScxGdyN${\rm Al}_{1-x-y}{\rm Sc}_x{\rm Gd}_y{\rm N}$ films have a high optical bandgap, enhanced piezoelectric ...

Advanced Science, EarlyView.A conversion‐resolved constitutive framework is developed for the hydrogen‐based direct reduction of iron oxide pellets. Effective reaction and transport timescales are inferred directly from measured trajectories and mapped against operating conditions, pellet architecture, and composition. The analysis reveals how late‐stage transport control emerges

Advanced Science, EarlyView.A biomimetic artificial intelligence system, PancDS, has been developed to distinguish pancreatic ductal adenocarcinoma from mass‐forming pancreatitis by adaptively integrating clinical data, radiomics, and deep learning features. Validated across multicenter, reader‐study, and prospective settings, PancDS improves diagnostic accuracy, particularly for

The use of spline-on-spline for the approximation of Cauchy principal value integrals
Applied Mathematics and Computation, 1996 The use of spline-on-spline approximations to estimate Cauchy principal value integrals and their derivatives is discussed. Better results than those obtained by differentiating traditional single spline approximations might be expected. Unfortunately, the proofs of convergence (Theorems 3.2, 3.3) appear to be flawed because of the assumption of ...

A note on bimodality in the log-likelihood function for penalized spline mixed models [PDF]
, 2009 For a smoothing spline or general penalized spline model, the smoothing parameter can be estimated using residual maximum likelihood (REML) methods by expressing the spline in the form of a mixed model.

Advanced Science, EarlyView.This study establishes a CT‐based radiomics framework to quantify intratumoral heterogeneity (ITH) in HNSCC. Using unsupervised clustering, tumor ROIs and VOIs are analyzed to calculate 2D/3D ITH scores. The score shows strong predictive value for prognosis and immunotherapy response, and is associated with tumor metabolism and immune microenvironment,
