4D Bioprinted Self‐Folding Scaffolds Enhance Cartilage Formation in the Engineering of Trachea

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A bilayer self‐folding scaffold, triggerable by humidity, is fabricated via 4D bioprinting for trachea engineering. An analytical model is derived to predict its radius of curvature, enabling its scalability. Cartilage progenitor cells seeded on the scaffold perceive scaffold final curvature and react to it, by enhancing the upregulation of pro ...

Spectral Polyhedra

open access: yesForum of Mathematics, Sigma
A spectral convex set is a collection of symmetric matrices whose range of eigenvalues forms a symmetric convex set. Spectral convex sets generalize the Schur-Horn orbitopes studied by Sanyal–Sottile–Sturmfels (2011). We study this class of convex bodies,

On p-convex sets and geodesics

open access: yesJournal of Differential Equations, 1988
On etudie les geodesiques sur une variete contrainte M a bord irregulier. On considere une classe d'ensembles irreguliers M qui permet d'obtenir des resultats d'existence et de multiplicite pour les ...

Printed Interconnects for Heterogeneous Systems Integration on Flexible Substrates

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
Key components (sensors, energy devices, communication devices, computing chips, and interconnects) of flexible hybrid electronic (FHE) system connected via conductive printed metal tracks. The figure in the insets shows out‐of‐plane printed interconnects providing opportunities for lithography‐free formation of VIAs, in‐plane access of UTCs pads, and ...

Intuitionistic fuzzy variational inequalities and their applications

open access: yesAIMS Mathematics
In this paper, a new class of generalized convex (concave) fuzzy mappings are introduced, which is called intuitionistic convex (concave) fuzzy mappings from the convex set $ {K\subseteq \mathbb{R}}^{n} $ to the set of intuitionistic fuzzy numbers.

Advanced Optical Integration Processes for Photonic‐Integrated Circuit Packaging

open access: yesAdvanced Materials Technologies, EarlyView.
Photonic integrated chip packaging is a growing technology that helps make devices faster, more efficient, and more compact by using light instead of electricity. This review highlights recent progress in making these chips work better at different levels, discusses current challenges like heat and alignment, and looks at future possibilities for ...

Large convex sets in difference sets

open access: yesMathematika
AbstractWe give a construction of a convex set with cardinality such that contains a convex subset with cardinality . We also consider the following variant of this problem: given a convex set , what is the size of the largest matching such that the set is convex?

Automatic Exposure Volumetric Additive Manufacturing

open access: yesAdvanced Materials Technologies, EarlyView.
Tomographic volumetric additive manufacturing (VAM) is resin‐based 3D printing technology, where objects are printed in seconds using volumetric light patterning. Although fast, tomographic VAM struggles to produce repeatable and accurate prints. This work demonstrates an automatic exposure method for tomographic VAM, resulting in commercial‐grade ...

Pick‐and‐Place Grippers with Tunable Adhesion from Capped Soft Hollow Pillar Structure

open access: yesAdvanced Materials Technologies, EarlyView.
Mushroom‐shaped soft hollow pillars (SHPs) with a mushroom cap, or capped SHPs (C‐SHPs) are introduced for improved tunable adhesion under pneumatic actuation. The mushroom cap optimizes stress distribution and alters crack initiation on the contact interface, leading to significantly improved adhesion strength and tunability.
