Apparatus and method for inspecting a bearing ball [PDF]

open access: yes, 1985
A method and apparatus for inspecting the surface of a ball bearing is disclosed which includes a base having a high friction non-abrasive base scanning surface. A holding device includes a cone-shaped cup recess in which a ball element is received.

Endothelial Cells Angiogenesis in Sulfated Glycosaminoglycan (GAG) Hydrogels Enhanced by Bioactive Glass‐Released Ions

open access: yesAdvanced Functional Materials, EarlyView.
A mechanically tunable hydrogel composed of gelatin, chondroitin sulfate and laminin promotes angiogenesis in vitro without the supplement of growth factors. Endothelial cells morphogenesis was further enhanced by medium conditioned with bioactive glass 58S‐released ions (Ca and Si), thus offering a promising strategy to vascularize 3D tissue ...

Willard Van Orman Quine's Philosophical Development in the 1930s and 1940s [PDF]

open access: yes, 2018
As analytic philosophy is becoming increasingly aware of and interested in its own history, the study of that field is broadening to include, not just its earliest beginnings, but also the mid-twentieth century.

Synergistic Compatibilization of CsPbBr3 Perovskites and HfO2 Nanocrystals for Hybrid Sensitized Nanoscintillators

open access: yesAdvanced Functional Materials, EarlyView.
Lead halide perovskite nanocrystals are promising scintillators but suffer from reabsorption losses and limited compatibility with high‐Z additives. Hybridization of CsPbBr3 nanocrystals with PbBr2‐passivated HfO2 nanoparticle sensitizers, achieved during or after synthesis, produces stable composites with maintained optical quality, improved ...

First to Score, First to Win? Comparing Match Outcomes and Developing a Predictive Model of Success Using Performance Metrics at the FIFA Club World Cup 2025

open access: yesApplied Sciences
In the present study, 96 teams’ performances across 48 matches in the group stage of the FIFA Club World Cup 2025 were analyzed. Teams scoring first won 62.5% of matches (p < 0.05), while goals were evenly distributed between halves (p > 0.05) and showed

Fully Bio‐Based Gelatin Organohydrogels via Enzymatic Crosslinking for Sustainable Soft Strain and Temperature Sensing

open access: yesAdvanced Functional Materials, EarlyView.
Enzymatically crosslinked gelatin‐based organohydrogels, fabricated through a fully bio‐based and scalable process, exhibit exceptional strain and temperature sensing capabilities with minimal interference from environmental humidity. These transparent, stretchable, and ionically conductive materials operate without synthetic fillers or dopants.

THE HISTORY OF RESEARCH ON LATVIAN CUP-MARKED STONES

open access: yesCulture Crossroads, 2022
The stones known as cup-marked stones stand out among stones with marks of ancient artificial treatment in north-eastern Europe, as well as in the rest of the world. So far in the literature the view has predominated that the number of cup-marked stones in Latvia is small in comparison with neigh- bouring countries.

Pattern formation during de novo assembly of the Arabidopsis shoot meristem [PDF]

open access: yes, 2007
Most multicellular organisms have a capacity to regenerate tissue after wounding. Few, however, have the ability to regenerate an entire new body from adult tissue. Induction of new shoot meristems from cultured root explants is a widely used, but poorly

Single‐Crystalline Lateral p‐SnS/n‐SnSe van der Waals Heterostructures by Vapor Transport Growth with In Situ Bi Doping

open access: yesAdvanced Functional Materials, EarlyView.
In‐situ doping during growth of SnSe and subsequent attachment of SnS produces high‐quality lateral pn‐heterojunctions between van der Waals semiconductors. Electron beam induced current measurements demonstrate electrically active pn‐junctions, paving the way for devices that harness charge separation at lateral interfaces in layered heterostructures.

From Sochi - 2014 to FIFA - 2018: a Fading Sovereignty? [PDF]

open access: yes, 2017
In this article, we uncover the dynamics and the evolution of Russian discourses of sovereignty before and after the Sochi 2014 Olympic Games using some elements of Foucauldian methodology and constructivist reading of sovereignty as an institution.
