Revisiting the “Stick‐Slip” Process via Magnetism‐Coupled Flexible Sensors with Bioinspired Ridge Architecture

Advanced Materials, EarlyView.
A sandwich‐like device for stick‐slip perception is developed, featuring a deformable bioinspired ridge layer with capability of lateral deformation and fast recovery. Coupled with magnetized functionality, the morphological transformation is capable to induce periodical electrical pulses which allows to revisit the stick‐slip process when human ...

Protein‐Like Polymers Targeting Keap1/Nrf2 as Therapeutics for Myocardial Infarction

Advanced Materials, EarlyView.
We describe a Keap1 targeting protein‐like polymer (PLP) which activates Nrf2, an important cytoprotective transcription factor for relieving myocardial infarction‐induced oxidative stress. This PLP increases cell survival in vitro in multiple relevant cardiac cell types and elicits pro‐reparative responses, improving cardiac function in a preclinical ...

Orbital Topology of Chiral Crystals for Orbitronics

Advanced Materials, EarlyView.
Chirality is ubiquitous in nature and constitutional for life. In chiral materials the intrinsic handedness, defined by their crystal structure, becomes a main driver for a novel electronic topology that is based on the orbital angular momentum rather than the electron spin.

Advanced Air Electrodes for Reversible Protonic Ceramic Electrochemical Cells: A Comprehensive Review

Advanced Materials, EarlyView.
Reversible protonic ceramic electrochemical cells (R‐PCECs) face challenges from sluggish and unstable oxygen reduction and evolution reactions in the air electrode. This review discusses recent progress in triple‐conducting air electrodes, emphasizing mechanisms, performance factors, and design strategies, offering guidance for creating efficient and ...

Recent Advances in Wide‐Bandgap Perovskite Solar Cells

Advanced Materials, EarlyView.
Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG

A theory of political cycles [PDF]

Journal of Economic Theory, 2008
We study how the proximity of elections affects policy choices in a model in which policymakers want to improve their reputation to increase their reelection chances. Policymakers' equilibrium decisions depend on both their reputation and the proximity of the next election.

Political Theory and Political Judgment

PS: Political Science & Politics, 1984
Few political theorists today try to show how the principles of theory should guide our judgments of policy. Theorists think that their job is done when they have explained the principles, or (more commonly) when they have interpreted the principles of other theorists.

Political Theory and Political Education

Higher Education Quarterly, 1955
The subject of this paper is very old and could readily be stated in terms of Plato’s Republic; the implication of the title, ‘Political Theory and Political Education’, is that I want to state it in terms of an inaugural lecture which was given by Professor Michael Oakeshott in March 1951, when he took over the famous Chair of Political Science at the

Governance as political theory

Critical Policy Studies, 2011
The concept of governance has become very fashionable over the past several decades, and indeed has become one of the most commonly used terms in political science. One French scholar, for example, has referred to this term as a “fetish.” Further, the term has become widely used in the discussions and publications of international organizations ...
