Stamps extraction using local adaptive k- means and ISODATA algorithms

open access: yesIndonesian Journal of Electrical Engineering and Computer Science, 2021
<span>One of the main difficulties facing the certified documents documentary archiving system is checking the stamps system, but, that stamps may be contains complex background and surrounded by unwanted data. Therefore, the main objective of this paper is to isolate background and to remove noise that may be surrounded stamp.

High‐Speed Atomic Force Microscopy Reveals the Dynamic Interplay of Membrane Proteins is Lipid‐Modulated

open access: yesSmall Science, Volume 5, Issue 9, September 2025.
High‐speed atomic force microscopy captures the lipid‐dependent clustering dynamics of pentameric FocA and tetrameric GlpF in supported lipid bilayers. Protein mobility, cluster stability, and packing geometry vary with lipid composition, revealing how membrane environments regulate supramolecular membrane protein organization.

Nanoparticle‐Coated X2CrNiMo17‐12‐2 Powder for Additive Manufacturing—Part II: Processability by Powder Bed Fusion of Metals Using a Laser Beam

open access: yesAdvanced Engineering Materials, Volume 27, Issue 14, July 2025.
In this manuscript, the processability of X2CrNiMo17‐12‐2 powder coated with silicon carbide, silicon, and silicon nitride nanoparticles is investigated. The amount of nanoparticles varies from 0.25 to 1 vol%. By coating the powder feedstock material with nanoparticles, an enlargement of the process window and an increase in the build rate are achieved.

Effects of Soil Structure on the Growth of Rice Roots

open access: yesJournal of Plant Nutrition and Soil Science, Volume 188, Issue 3, Page 402-407, June 2025.
ABSTRACT Soil pore structure has a large impact on plant root architecture, but it is difficult to study due to secondary impacts from bulk density, carbon, nutrients, and other properties. Here, we isolated soil pore structure by forming controlled soil structures in repacked columns. To generate a non‐structured treatment, sieved soil was packed to 1.
