Classifying pro-fibrations and shape fibrations
Journal of Pure and Applied Algebra, 1986 We first describe some categories. Let TOP denote the category whose objects are topological spaces and whose morphisms are continuous maps. Let \(TOP^ N\) denote the category whose objects are the inverse systems in TOP indexed by the set of natural numbers \({\mathbb{N}}\) (with continuous bonding maps).

Advanced Materials, EarlyView.Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

Piecewise linear fibrations [PDF]
Pacific Journal of Mathematics, 1987 A PL \((=\) piecewise linear) fibration is a Hurewicz fibration p: \(E\to B\) such that E, B are compact polyhedra and p is a PL map. Very important examples are PL manifold bundles (i.e. PL locally trivial bundles whose fibers are compact PL manifolds with boundary). The present paper establishes a PL link between the category of PL fibrations and the

Advanced Materials, EarlyView.Structural water is harnessed as an active co‐monomer to drive supramolecular polymerization in bulk water. Zinc(II) Salphen complexes confine water molecules to form hollow, metal–organic nanofibers that assemble into adaptive hydrogels with thermoresponsive mechanics and selective chiral recognition.

Extending fibrations on knot complements to ribbon disk complements
, 2018 We show that if $K$ is a fibered ribbon knot in $S^3=\partial B^4$ bounding ribbon disk $D$, then with a transversality condition the fibration on $S^3\setminus\nu(K)$ extends to a fibration of $B^4\setminus\nu(D)$.

Advanced Materials Interfaces, EarlyView.ABSTRACT This research focused on characterizing graphitic carbon nitride (g‐C3N4) nanocomposites incorporated with ZnO and Ag2O nanoparticles, and carrageenan to remove heavy metals. The ZnO/Ag2O@ g‐C3N4 and ZnO/Ag2O/g‐C3N4@Carr nanocomposites demonstrated thermal stability of 97.40% (108.81°C) and 82.80% (188.99°C) for TGA.

Rank jumps and multisections of elliptic fibrations on K3 surfaces
Forum of Mathematics, SigmaWe consider the countably many families $\mathcal {L}_d$ , $d\in \mathbb {N}_{\geq 2}$ , of K3 surfaces admitting an elliptic fibration with positive Mordell–Weil rank. We prove that the elliptic fibrations on the very general member of these

Advanced Materials Technologies, EarlyView.This critical review presents a comprehensive roadmap for the precision 3D printing of cellulose. Quantitative correlations link ink formulation and rheological properties to print fidelity and final material performance. This framework guides the development of advanced functional materials, from biomedical scaffolds to electromagnetic shielding ...

Ample vector bundles and intrinsic quadric fibrations over irrational curves
Le Matematiche, 2000 Let E be an ample vector bundle of rank r ≥ 2 on a smooth complex projective variety X. This work is part of the following problem: to study and classify the pair (X, E) assuming the existence of a regular section s ∈Γ (X, E) whose zero locus is a ...

Journal of High Energy Physics, 2018 We continue to develop the program initiated in [1] of studying supersymmetric AdS3 backgrounds of F-theory and their holographic dual 2d superconformal field theories, which are dimensional reductions of theories with varying coupling. Imposing 2d N=02 $
