Redox dual‐defects (Cs substitution and O vacancies) in 2D hydrated WO3 steer O2 activation toward selective singlet oxygen evolution. WO‐CO achieves 8.6–15.8 times higher 1O2 production than single‐defect or pristine catalysts, enabling efficient pollutant mineralization via a pathway‐selective photocatalytic mechanism.

Complex Bifurcation of the Two-Degree-of-Freedom Nonlinear Conveyor System
A two-degree-of-freedom nonlinear moving belt system is investigated, which considers the possibility of two oscillators sticking or sliding on the moving belt simultaneously.

Social Changes and “Points of no Return”: an Attempt to Conceptualize
The modern world is characterized by fluidity, changeability, and unpredictability. In particular, social life is full of events that often inspire fear, affect and have unpredictable social effects.

Bifurcation analysis of surge and rotating stall in the Moore-Greitzer compression system [PDF]
A simple compression system model, described by a set of three ordinary nonlinear differential equations (the Moore-Greitzer model) is studied using bifurcation analysis to give a qualitative understanding of the presence of surge and rotating stall ...

Double‐Interpenetrating Composite Bioink for Multi‐Component 3D Bioprinting and Biofabrication
Marine‐polysaccharides‐derived double interpenetrating network hydrogel‐based bioink, combining the attributes of physical and ionic crosslinking, enables room‐temperature bioprinting of mechanically defined structures that can be handled and are cytocompatible.

Energy profile and bifurcation analysis in softening plasticity [PDF]
Bifurcations of solutions and energy profile in softening plasticity are discussed in this paper. The localized and non-localized solutions are obtained for a simple softening bar; the second-order derivatives of the incremental energy are evaluated ...

Shaping Matter with Acoustic Waves: From Particles to Functional Structures
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

The Cauchy problem for a nonlinear system of differential equations with a Stieltjes integral (loads) of the desired solution is considered. The equation contains bifurcation parameters where the system has a trivial solution for any values.

Complementing maps, continuation and global bifurcation [PDF]
We state, and indicate some of the consequences of, a theorem whose sole assumption is the nonvanishing of the Leray- Schauder degree of a compact vector field, and whose conclusions yield multidimensional existence, continuation and bifurcation ...
