Spheroid Cell Aggregation Enhanced by Enzyme‐Free Ultrasound‐Detached Cells

open access: yesAdvanced Biology, EarlyView.
This study demonstrates that ultrasound‐based, enzyme‐free cell detachment accelerates spheroid formation by preserving surface proteins, reducing variability, and enhancing cell aggregation. Comparable engraftment and improved spatial organization in co‐cultured spheroids are observed.

Modelling Atherosclerotic Plaque Cap Mechanics: Microcalcifications Reduce Mechanical Properties in Mesenchymal Stromal Cell‐Based Model

open access: yesAdvanced Biology, EarlyView.
This study develops a tissue‐engineered model of the atherosclerotic cap using human mesenchymal stromal cells (MSCs). After 2 weeks of culture to produce a collagenous matrix, a mineralizing medium induces microcalcifications over 4 weeks. These constructs, imaged with second harmonic generation microscopy, lead to reduced ultimate stress at rupture ...

Tribological Characteristics between Snow and Steel and in Snow - Development of Annular Shearing Type Experimental Analysis System -

open access: yesTribology Online, 2015
Characteristics of friction and adhesion/cohesion between snow and SS400 steel in a shearing velocity range of 2.5-25.4 m/s, as well as in snow itself in a shearing velocity range of 0.5-2.5 m/s, were analyzed by using a specially developed annular ...

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

La crisis europea y el mito de la recuperación irlandesa: una mirada

open access: yesRevista de Economía y Estadística, 2016
En este artículo en primer lugar examino los puntos principales de la crisis de la eurozona (UME), mostrando que la credibilidad de un tipo de cambio fijo, junto con la libre circulación de capitales en la UME determinó un exceso de confianza, una caída

Prefabricated Images in Young Children’s Text-Making at School

open access: yesDesigns for Learning, 2016
In classrooms where computers are used as tools for text-making, images and photographs from e.g. Google, here called “prefabricated images”, can be selected and copied into texts and combined with writing. In this article children’s use of prefabricated

Cohesion of object histories

open access: yesTheoretical Computer Science, 1989
In an earlier paper, the first author and \textit{K. Tanaka} [ACM Trans. Database Syst. 11, 186-212 (1986; Zbl 0602.68098)] introduced a record- based, algebraically-oriented, event-driven model for describing historical data for objects (here called ``object histories'').

Mechanisms of Increasing Weld Depth during Temporal Power Modulation in High‐Power Laser Beam Welding

open access: yesAdvanced Engineering Materials, EarlyView.
Temporal power modulation increases weld depth in high‐power laser beam welding of dissimilar round bars by nearly 20% compared to same average continuously welded welding power. The mechanism of action also applies to sheet welding and depends on the inertia of keyhole depth for the modulated laser beam power.

Genius loci as the inner regional-cohesion force which enables formation of the fractal-social structures [PDF]

open access: yesAnnales Scientia Politica, 2019
Although the term “genius loci” has been known and used since ancient civilizations, it was considered almost unimportant in a technically industrialized and competitive world.
