Leveraging modified ex situ tomography data for segmentation of in situ synchrotron X‐ray computed tomography

Journal of Microscopy, EarlyView.
Abstract In situ synchrotron X‐ray computed tomography enables dynamic material studies. However, automated segmentation remains challenging due to complex imaging artefacts – like ring and cupping effects – and limited training data. We present a methodology for deep learning‐based segmentation by transforming high‐quality ex situ laboratory data to ...

Trueness of the apical and middle root portion segments of 3D‐printed removable die and alveolar cast designs manufactured using stereolithographic 3D printing

Journal of Prosthodontics, EarlyView.
Abstract Purpose The present study evaluated the effects of the root portion design, segment (middle vs. apical), and part (die vs. cast) on the trueness of three‐dimensional (3D)‐printed removable die‐cast complex. Material and Methods The trueness of apical and middle segments of the root portion of 45 3D‐printed removable dies and casts with three ...

Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.

Effect of margin thickness and cement gap on the fabrication and fit accuracy of additively manufactured crowns in definitive resins with different filler content

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate how commercially available composite resins in varying filler content affect the fabrication and fit accuracy (trueness and precision) of additively manufactured (AM) definitive crowns with different margin thickness and cement gaps by comparing them to subtractively manufactured (SM) polymer‐infiltrated ceramic crowns ...

Effects of printing temperature and post‐curing duration on the dimensional reproducibility and fracture load of 3D‐printed dental prostheses: An exploratory study

Journal of Prosthodontics, EarlyView.
Abstract Purpose This in vitro study aimed to evaluate the effects of printing temperature and post‐curing duration on the dimensional reproducibility and mechanical properties of three‐dimensional (3D)–printed dental prostheses. Materials and Methods Photopolymer specimens were fabricated using a stereolithographic 3D printer at two temperatures: room

Surface properties and biofilm formation of a manufacturer‐reinforced, nanographene‐modified pre‐polymerized CAD‐CAM polymethylmethacrylate denture base material: An in vitro study

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the surface roughness, hydrophobicity, and Candida albicans biofilm formation of three denture base materials, including two computer‐aided design and computer‐aided manufacturing (CAD‐CAM) polymethylmethacrylate (PMMA) resins and one conventional heat‐polymerized PMMA, before and after thermocycling (TC).

Systematic Approach for Carbonate and Volcanic Facies Classification Based on Textural and Structural Variations Observed in Brazilian Pre‐Salt Acoustic Image Logs

Journal of Petroleum Geology, EarlyView.
ABSTRACT Facies characterization in carbonate reservoirs remains challenging due to their pronounced textural and structural heterogeneity. Variations in grain packing, cementation, and diagenetic overprints produce contrasting acoustic responses in borehole image logs, often limiting the reproducibility of facies interpretation.

Using reflectance spectra and Pl@ntNet to identify herbarium specimens: a case study with Lithocarpus

New Phytologist, EarlyView.
Summary The digitisation of plant collections is bringing large quantities of information into accessible electronic databases. However, in recent decades, traditional taxonomic work in collections has declined, meaning that more specimens are only determined to family or genus, particularly when lacking key identification structures.

Heat‐evolved coral photosymbionts exhibit dampened stress responses across distinct physiological contexts

New Phytologist, EarlyView.
Summary Experimental evolution under elevated temperatures has generated heat‐evolved (HE) strains of Symbiodiniaceae that enhance coral bleaching tolerance. However, the biomolecular mechanisms underlying this resilience remain poorly understood. We conducted a laboratory heat‐stress experiment and applied synchrotron‐based Fourier transform infrared (

Climate change and crop resilience: harnessing metabolomics for predicting stress tolerance

New Phytologist, EarlyView.
Summarised methodology for metabolite biomarker discovery and genomic targets selection for those metabolites to predict high‐throughput phenotypic and agronomic traits of interest for direct uptake in breeding programmes. Summary Global warming is driving climate change to levels not experienced since the advent of agriculture, primarily due to ...
