Ultrafast opto-magnetic effects induced by nitrogen-vacancy centers in diamond crystals

APL Photonics, 2022
The current generation of quantum sensing technologies using color centers in diamond crystals is primarily based on the principle that the resonant microwave frequency of the luminescence between quantum levels of the nitrogen-vacancy (NV) center varies

Fuzzy Functional Dependency and the Resolution Principle

Informatica, 2005
Summary: We establish equivalence between a theory of fuzzy functional dependences and a fragment of fuzzy logic. We give a way to interpret fuzzy functional dependences as formulas in fuzzy logic. This goal is realized in four steps. Truth assignment of attributes is defined in terms of closeness between two tuples in a fuzzy relation.

Resolvable ambiguity: principled resolution of syntactically ambiguous programs

Proceedings of the 30th ACM SIGPLAN International Conference on Compiler Construction, 2021
When building a new programming language, it can be useful to compose parts of existing languages to avoid repeating implementation work. However, this is problematic already at the syntax level, as composing the grammars of language fragments can easily lead to an ambiguous grammar.

Ultracold neutrons, quantum effects of gravity and the Weak Equivalence Principle

, 2002
We consider an extension of the recent experiment with ultracold neutrons and the quantization of its vertical motion in order to test the Weak Equivalence Principle.

Iterative reconstruction methods and the resolution principle for fast-ion loss detector measurements

Nuclear Fusion
Fast-ion loss detectors (FILDs) are crucial for analyzing fast-ion dynamics in magnetically confined fusion plasmas. A core challenge is to derive an accurate ion velocity distribution, requiring treatment of thousands of remapped camera frames for a ...

Reevaluating the Application of Contrarius Actus Principle in Land Case Resolution

Nurani Hukum
This research addresses the urgent national issue of land disputes in Indonesia, where legal certainty is paramount. The National Land Agency (BPN) has the authority to cancel land certificates it issues, based on the contrarius actus principle, but its ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Subluminal OPERA Neutrinos

, 2011
The OPERA collaboration has announced to have observed superluminal neutrinos with a mean energy 17.5 GeV, but afterward the superluminal interpretation of the OPERA results has been refuted theoretically by Cherenkov-like radiation and pion decay.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
