Unveiling Exsolution‐Induced Giant Electronic and Magnetic Property Changes in Non‐Stoichiometric Titanate Perovskite Thin Films

Advanced Materials, EarlyView.
A giant insulator to metal transition and emergent superparamagnetism are revealed by nanoparticle exsolution in non‐stoichiometric titanate perovskite thin films. By combining transport, synchrotron spectroscopy, and first‐principles calculations, this work reveals how defect reconfiguration and lattice reconstruction fundamentally reshape electronic ...

Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

Advanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

Recent Progress in the Phase‐Controlled Synthesis of Ruthenium Nanocrystals for Catalytic Applications

Advanced Materials, EarlyView.
Template effect and kinetic control enable crystal‐phase engineering of Ru nanocrystals, granting access to either metastable fcc‐Ru or stable hcp‐Ru with distinct surface structures, thermal stabilities, and catalytic behaviors. Moreover, the hcp‐Ru can further serve as an epitaxial template to direct Pd and Rh nanocrystals into the metastable hcp ...

Advancing Lithium–Oxygen Batteries: Pioneering Cathode Catalyst Innovation and Artificial Intelligence‐Driven Design Paradigms

Advanced Materials, EarlyView.
This review summarizes the principles and challenges of nonaqueous lithium‐oxygen batteries and recent advances in cathode catalysts, including carbon‐based materials, metals, oxides, sulfides, nitrides, carbides, and redox mediators. It highlights emerging design strategies and artificial intelligence‐driven approaches, emphasizing data‐assisted ...

Theory of constraints

International Journal of Operations and Production Management, 1998
A new approach to the management of production and operations was developed by Goldratt in the late 1970s. Now known as the theory of constraints (TOC), it provides a coherent management theory for running an organisation. It has two major components: a philosophy which underpins the working principle of on‐going improvement, and a generic approach for

TOWARD A THEORY OF CONSTRAINTS

Journal of Marital and Family Therapy, 1999
Grounded in the cybernetic concept of negative explanation, the theory of constraints examines how human systems are kept from solving problems. To identify constraints, therapists must know where to look for them and what to look for. The theory proposes that contraints exist among the levels of a biopsychosocial system, which include biology, person,

The Theory of Grammar Constraints

2006
By introducing the Regular Membership Constraint, Gilles Pesant pioneered the idea of basing constraints on formal languages. The paper presented here is highly motivated by this work, taking the obvious next step, namely to investigate constraints based on grammars higher up in the Chomsky hierarchy.

Constraints in Covariant Field Theories

Physical Review, 1951
In this paper we have considered certain problems which arise when one attempts to cast a covariant field theory into a canonical form. Because of the invariance properties of the theory, certain identities exist between the canonical field variables.

Constraint Logic Programming over unions of Constraint theories

1996
Summary: In this paper, we present an extension of the Jaffar-Lassez constraint logic programming scheme that operates with unions of constraint theories with different signatures and decides the satisfiability of mixed constraints by appropriately combining the constraint solvers of the component theories.

The Partitive Constraint in Optimality Theory

Journal of Semantics, 2000
This paper discusses a case of syntax/semantics interaction of a characteristically optimality-theoretic kind. Finnish partitive constructions exhibit a case alternation that is partly semantically, partly syntactically driven. The crucial semantic condition that plays a role in case selection is quantitative determinacy, which replaces the ...
