Impact of the Process Atmosphere During Hot Isostatic Pressing on the Near‐Surface Composition of an Additively Manufactured Austenitic High‐Interstitial Steel

open access: yesAdvanced Engineering Materials, EarlyView.
A high interstital austenitic steel is additively manufactured and postdensified by HIP to eliminate gas porosity. Thereby, the loss of N and Mn in Ar HIP atmosphere is investigated. Further, HIP using N2 atmosphere is investigated which led to excessive nitride formation.

Narrow-band imaging and a search for planetary nebulae

open access: yes, 1999
We summarize the results of narrow-band (Hα and [O III] λ 5007 Å) imaging of eight planetary nebulae taken during recent observing campaigns: We present the probably largest known PN, MWP 1, with a linear diameter of about 6 pc. We show first narrow-band

Anticorrosive Performance of Smart Epoxy Coatings With Poly(urea‐formaldehyde) Microcapsules Filled With 5‐Ethylidene‐2‐norbornene

open access: yesAdvanced Engineering Materials, EarlyView.
PUF/ENB microcapsules were synthesized based on a sequential factorial design and incorporated into an epoxy matrix. Their anticorrosive action, associated with the self‐healing mechanism, demonstrated that the addition of microcapsules to the coating improved anticorrosive performance compared to pure epoxy coatings, particularly when the encapsulate ...

Magnifying Endoscopy for Intestinal Follicular Lymphoma Is Helpful for Prompt Diagnosis

open access: yesGut and Liver, 2013
The representative endoscopic features of primary intestinal follicular lymphoma are well known as small whitish polypoid nodules, but a magnified view has only been described in a few case reports.

Quasar Detection Using Multi-Narrow-Band Imaging

open access: yes, 2007
: Multi-narrow-band imaging for multi-object spectrophotometry is a technique very well suited for large surveys, like those that can be made with zenithal telescopes.

Narrow band imaging combined with water immersion technique in the diagnosis of celiac disease

open access: yes, 2014
BACKGROUND: The "multiple-biopsy" approach both in duodenum and bulb is the best strategy to confirm the diagnosis of celiac disease; however, this increases the invasiveness of the procedure itself and is time-consuming.

Thermal Cycle–Microstructure–Property Relationships in Rail Steel Heat‐Affected Zone Simulated by Gleeble

open access: yesAdvanced Engineering Materials, EarlyView.
Microstructural evolution of premium rail steel during flash butt welding (FBW), comparing physically simulated heat‐affected zones with actual weld regions. Thermal cycles induce phase transformations and microstructural heterogeneity that influence weld quality and mechanical performance. These findings provide insights into optimizing FBW parameters

Deep-learning-based image acquisition support tool for endoscopic narrow band imaging of the larynx

open access: yes, 2023
Narrow band imaging (NBI) enables a contrast-enhanced imaging of mucosal blow-vessels. Nowadays NBI is a standard feature in many endoscopes. NBI is increasingly being applies in clinical investigations of the head-neck region.

The usefulness of the NBI – narrow band imaging for the larynx assessment [PDF]

open access: yes, 2018
Narrow band imaging (NBI) by enhancing the contrast between the mucosal epithelium and submucosal vessels facilitates diagnosis of precancerous and cancerous lesions, as well as hypertrophic lesions such as laryngeal papillomatosis.

All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

open access: yesAdvanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.
