Regulating the Interphase Strain in High‐Entropy Oxide Thin Films – An Approach to Attaining Giant Energy Storage Capability under Moderate Electric Fields

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates an interphase strain engineering strategy to regulate capacitive energy storage performance in high‐entropy oxide thin films. Through introducing pyrochlore nanocolumns, the polarization response of perovskite unit cells is strengthened, yielding recoverable energy densities up to 93 J cm−3 with an efficiency of 83% under ...

Precise time-matching in chimpanzee allogrooming does not occur after a short delay. [PDF]

open access: yesPLoS ONE, 2018
Allogrooming is a key aspect of chimpanzee sociality and many studies have investigated the role of reciprocity in a biological market. One theoretical form of reciprocity is time-matching, where payback consists of an equal duration of effort (e.g ...

Diophantine geometry and non-abelian reciprocity laws I [PDF]

open access: yes, 2015
We use non-abelian fundamental groups to define a sequence of higher reciprocity maps on the adelic points of a variety over a number field satisfying certain conditions in Galois cohomology.

Generation method of GPS L1C codes based on quadratic reciprocity law

open access: yes, 2013
A new code concept is used for the L1 civil (L1C) signal of the global positioning system (GPS). The generation of L1C codes is quite different from the generation of traditional ranging codes.

Computational Modeling of Reticular Materials: The Past, the Present, and the Future

open access: yesAdvanced Materials, EarlyView.
Reticular materials are advanced materials with applications in emerging technologies. A thorough understanding of material properties at operating conditions is critical to accelerate the deployment at an industrial scale. Herein, the status of computational modeling of reticular materials is reviewed, supplemented with topical examples highlighting ...

Four levers of reciprocity across human societies: concepts, analysis and predictions

open access: yesEvolutionary Human Sciences, 2022
This paper surveys five human societal types – mobile foragers, horticulturalists, pre-state agriculturalists, state-based agriculturalists and liberal democracies – from the perspective of three core social problems faced by interacting individuals ...

Constructing Class invariants [PDF]

open access: yes, 2012
Shimura reciprocity law allows us to verify that a modular function is a class invariant. Here we present a new method based on Shimura reciprocity that allows us not only to verify but to find new class invariants from a modular function of level $N ...

Multi‐Scale Modeling of a 3D Soft Magnetoelectric Patch for Wireless Nerve Stimulation

open access: yesAdvanced Materials Interfaces, EarlyView.
Core‐shell, magnetoelectric nanoparticles (MENPs) can serve as wireless electric nano‐sources, thanks to their ability to generate high levels of electricity, when stimulated by a human‐safe external magnetic field. By combining MENPs with soft, biocompatible polymeric matrices and optimizing its composite configuration and electrical behavior via ...

Shapes Displayed with Durations in the Microsecond Range Do Not Obey Bloch's Law of Temporal Summation

open access: yesi-Perception, 2013
Shape patterns were displayed with simultaneous brief flashes from a light-emitting diode array. Flash durations in the microsecond range and luminous intensities were adjusted to vary the degree of successful shape recognition.

Law And Literature: The Construction of me and Other

open access: yesRevista de Direito, Arte e Literatura, 2015
One of the fundamental legal concepts is person as its seem by the law. The aim of this study is to connect the concept of person and the concepts of "me" and "other," and highlight the role of literature in the construction of those concepts.
