Combining ACSL Specifications and Machine Code

open access: yesТруды Института системного программирования РАН, 2018
When developing programs in high-level languages, developers have to make assumptions about the correctness of the compiler. However, this may be unacceptable for critical systems.

De Rerum Natura: How Do Halide Perovskites Self‐Heal From Damage?

open access: yesAdvanced Materials, EarlyView.
How can lead‐halide‐perovskites self‐heal after damage from light, heat, mechanical strain, or radiation? We show that reversible chemical defects underly performance losses and recovery, highlighting the roles of halide and proton migration, redox‐driven reactions, and acid‐base equilibria.

Diverse Cation Exchange in Layered Titanate Nanostructures for Tailored Catalysis

open access: yesAdvanced Materials, EarlyView.
H+(H3O+)‐intercalated layered titanate enables stable intercalation of 42 single‐metal and multication combinations. Alkali‐metal intercalation tunes Rh charge density, yielding an efficient propylene hydroformylation catalyst. These results establish a generalizable intercalation platform for rational catalyst design and provide a library supporting ...

The Coupling of Ferroelectric Polarization and Oxygen Vacancy Migration Enables Electrically Controlled Thermal Memories

open access: yesAdvanced Materials, EarlyView.
Ferroelectric Hf0.5Zr0.5O2 epitaxial thin films exhibit a non‐volatile, electrically controlled thermal conductivity enabled by the coupling between oxygen vacancy migration, acting as phonon scatterers, and ferroelectric polarization, acting as ion migration valve.

An Overview of Data Models of Object-Oriented DBMSs

open access: yesТруды Института системного программирования РАН, 2018
Object-oriented DBMS theory is one of the most prospective areas of modern database theory, along with deductive and temporal DBMS. Nevertheless, a high variety of different approaches and absence of a uniform standard, both in theoretical OODBMS area ...

Large‐Area 2D Metasurface‐Based Triboelectric E‐Skin Arrays: Contact & Proximity Tactile Mapping with Broadband Acoustic Readouts

open access: yesAdvanced Materials, EarlyView.
Metasurface‐engineered NC‐TENG arrays integrate tactile pressure mapping, non‐contact gesture sensing, and acoustic signal readouts in one ultrathin module, and outperforms pristine PDMS in terms of electrical output and real‐time spatial mapping for next‐gen wearables.

The science writing heuristic approach and the role of domain general reasoning in explaining the growth of inductive and deductive inferences in mathematics and science

open access: yesDiscover Education
An ongoing debate in education has centered on the concept of domain-general reasoning practices and whether such a position can explain how student learning in one discipline can influence their practices in another.

What is Moral Application? Towards a Philosophical Theory of Applied Ethics [PDF]

open access: yes, 2017
The aim of this paper is to offer some philosophical remarks concerning the concept of moral application in applied ethics. In doing so, I argue in favour of a philosophical approach towards applied ethics as a unitary form of moral experience.

Solvent‐Mediated Reactivity Control of Lewis‐Paired Dopants as a Versatile Strategy for Tunable and Stable Doping of Organic Semiconductors

open access: yesAdvanced Materials, EarlyView.
Solvent‐mediated reactivity control of Lewis‐paired dopants enables highly efficient, finely tunable, and stable doping of organic semiconductors. The optimally doped semiconductor films exhibit superior thermoelectric performance and doping stability, feature delocalized polarons along structurally ordered polymer backbones, and outperform ...

A conceptual treadmill: the need for ‘middle ground’ in clinical decision making theory in nursing [PDF]

open access: yes, 1999
This paper explores the two predominant theoretical approaches to the process of nurse decision making prevalent within the nursing research literature: systematic-positivistic approaches as exemplifed by information processing theory, and the intuitive ...
