Habitat Radiomics Predict HPV Status in Oropharyngeal Cancer

open access: yesCancer Medicine, Volume 14, Issue 24, December 2025.
ABSTRACT Objective This study developed a habitat‐based radiomics classifier from CT images to predict HPV status in oropharyngeal cancer (OPC). Methods We analyzed pretreatment CT scans from 192 OPC patients. Tumor habitats were generated using a two‐level unsupervised clustering approach, and radiomics features were calculated from both intratumoral ...

Mining an Anthropocene in Japan: On the making and work of geological imaginaries

open access: yesTransactions of the Institute of British Geographers, Volume 50, Issue 3, September 2025.
Short Abstract This article addresses how the lithic and the drift might be reworked as an Anthropocene material outside of a chronostratigraphy. Revisiting the finding of a floating fern fossil at the Hashima mine, we delve into a complex array of Geological imaginaries, and undertake our own speculative work.

An Effective Classification Scheme for Hyperspectral Image Based on Superpixel and Discontinuity Preserving Relaxation

open access: yesRemote Sensing, 2019
Hyperspectral image (HSI) classification is one of the most active topics in remote sensing. However, it is still a nontrivial task to classify the hyperspectral data accurately, since HSI always suffers from a large number of noise pixels, the ...

LBP Stereo Matching Algorithm Based on LSC Image Segmentation [PDF]

open access: yesJisuanji gongcheng, 2018
In the traditional global stereo matching methods,pixel-based belief propagation has a large amount of computation and a single pixel point can easily cause errors.Therefore,on the basis of the image segmentation processing methods,a Loopy Belief ...

Detecting Changes in Space‐Varying Parameters of Local Poisson Point Processes

open access: yesEnvironmetrics, Volume 36, Issue 5, July 2025.
ABSTRACT Recent advances in local models for point processes have highlighted the need for flexible methodologies to account for the spatial heterogeneity of external covariates influencing process intensity. In this work, we introduce tessellated spatial regression, a novel framework that extends segmented regression models to spatial point processes,

Enhanced Leaf Disease Segmentation Using U‐Net Architecture for Precision Agriculture: A Deep Learning Approach

open access: yesFood Science &Nutrition, Volume 13, Issue 7, July 2025.
This study proposes a deep learning‐based approach for leaf disease identification using the U‐Net architecture for precise segmentation. By training on a dataset of 7056 annotated leaf images, the model effectively distinguishes between healthy and diseased regions, achieving 99.70% training accuracy and 98.99% validation accuracy in 40 epochs.

The Biarylitides: Understanding the Structure and Biosynthesis of a Fascinating Class of Cytochrome P450 Modified RiPP Natural Products

open access: yesChemBioChem, Volume 26, Issue 7, April 1, 2025.
The biarylitides are fascinating RiPP natural products with small core peptides and diverse peptide crosslinks performed by cytochrome P450 enzymes. Here, we address the discovery and diversity of the biarylitides, methods to analyse these constrained cyclic peptides, the structures of the biarylitide P450 enzymes and address alternate catalytic ...

Hyperspectral Superpixel-Wise Glioblastoma Tumor Detection in Histological Samples

open access: yesApplied Sciences, 2020
The combination of hyperspectral imaging (HSI) and digital pathology may yield more accurate diagnosis. In this work, we propose the use of superpixels in HS images for combining regions of pixels that can be classified according to their spectral ...
