Adaptive Machine Learning for Electronic Nose‐Based Forensic VOC Classification

Advanced Science, EarlyView.
A 32‐element electronic nose enhanced with machine learning demonstrates exceptional accuracy in differentiating between living and deceased individuals (98.1%), discriminating human and animal specimens (97.2%), and estimating postmortem intervals.

Multivariate error function based neural network approximations

Journal of Numerical Analysis and Approximation Theory, 2014
Here we present multivariate quantitative approximations of real and complex valued continuous multivariate functions on a box or \(\mathbb{R}^{N},\) \(N\in \mathbb{N}\), by the multivariate quasi-interpolation, Baskakov type and quadrature type neural ...

GinAR: An End-To-End Multivariate Time Series Forecasting Model Suitable for Variable Missing [PDF]

Knowledge Discovery and Data Mining
Multivariate time series forecasting (MTSF) is crucial for decision-making to precisely forecast the future values/trends, based on the complex relationships identified from historical observations of multiple sequences.

Optimal designs for multivariate interpolation

Journal of Multivariate Analysis, 1990
AbstractOptimal interpolation designs are given for estimation of the value of a linear functional of an unknown polynomial mean. For example, optimal designs are given for estimation of the average value of a multivariate polynomial over a sphere of radius a < r when observations are available only in the region r ≤ ∥x∥ ≤ R.

Multivariate Quadratic Transformations and the Interpolation Kernel [PDF]

Symmetry, Integrability and Geometry: Methods and Applications, 2018
We prove a number of quadratic transformations of elliptic Selberg integrals (conjectured in an earlier paper of the author), as well as studying in depth the "interpolation kernel", an analytic continuation of the author's elliptic interpolation functions which plays a major role in the proof as well as acting as the kernel for a Fourier transform on ...

Gut Parabacteroides distasonis‐derived Indole‐3‐Acetic Acid Promotes Phospholipid Remodeling and Enhances Ferroptosis Sensitivity via the AhR‐FASN Axis in Bladder Cancer

Advanced Science, EarlyView.
Indole‐3‐acetic acid (3‐IAA) derived from gut P. distasonis binds to AhR in bladder cancer cells and downregulates FASN transcription, thereby increasing sensitivity to ferroptosis and suppressing the development of bladder tumors. Specifically, 3‐IAA treatment leads to an increase in the proportion of PC/PE‐PUFAs and a decrease in the proportions of ...

Korovkin-type convergence results for multivariate Shepard formulae

Journal of Numerical Analysis and Approximation Theory, 2009
We present a new convergence proof for classic multivariate Shepard formulae within the context of Korovkin-type convergence results for positive operators on spaces of continuous real valued functions.

Interpolation by Uni- and Multivariate Generalized Splines

Journal of Approximation Theory, 1995
AbstractLagrange interpolation by finite-dimensional spaces of uni- and multivariate generalized spline functions (including polynomial splines) is studied. Using a condition of Schoenberg-Whitney type, it is shown how to change an almost interpolation set in order to obtain a set which admits unique Lagrange interpolation.

BRD4 Signaling Maintains the Differentiated State of β Cells

Advanced Science, EarlyView.
The comprehensive exploration revealed the critical role of BRD4 in β cells. BRD4 plays a fundamental role in maintaining β cell differentiation because both long‐term and acute BRD4 deficiency result in a reduction in insulin secretion and downregulation of differentiation markers.

Radiomics‐Based Unsupervised Clustering Identifies Subtypes Associated With Prognosis and Immune Microenvironment in Clear Cell Renal Cell Carcinoma: A Multicenter Study

Advanced Science, EarlyView.
This study developed an unsupervised radiomics system integrating CT imaging and multi‐omics data to stratify clear cell renal cell carcinoma into two subtypes with distinct clinical outcomes. Cluster 1 showed lower recurrence risk and active immunity, while Cluster 2 exhibited higher recurrence risk, enriched VHL/KDM5C mutations, immunosuppressive ...
