Critical behaviours of contact near phase transitions [PDF]
, 2014 A central quantity of importance for ultracold atoms is contact, which measures two-body correlations at short distances in dilute systems. It appears in universal relations among thermodynamic quantities, such as large momentum tails, energy, and ...

Delimitations of the Professional Judgment within an Economic Environment [PDF]
Global Economic Observer, 2020 The professional judgment is a base concept “sine-qua-non” within a company because it displays the intrinsic attribute for performing the activity. In our accepting, bringing together the determinant factors of the professional judgment and also the ...

Search efficiency of discrete fractional Brownian motion in a random distribution of targets
Physical Review Research, 2021 Efficiency of search for randomly distributed targets is a prominent problem in many branches of the sciences. For the stochastic process of Lévy walks, a specific range of optimal efficiencies was suggested under variation of search intrinsic and ...

Universal machine learning for the response of atomistic systems to external fields
Nature Communications, 2023 Machine learned interatomic interaction potentials have enabled efficient and accurate molecular simulations of closed systems. However, external fields, which can greatly change the chemical structure and/or reactivity, have been seldom included in ...

Bloch theorem dictated wave chaos in microcavity crystals
Light: Science & Applications, 2023 Universality class of wave chaos emerges in many areas of science, such as molecular dynamics, optics, and network theory. In this work, we generalize the wave chaos theory to cavity lattice systems by discovering the intrinsic coupling of the crystal ...

Communication complexity and intrinsic universality in cellular automata
Theoretical Computer Science, 2011 The notions of universality and completeness are central in the theories of computation and computational complexity. However, proving lower bounds and necessary conditions remains hard in most of the cases. In this article, we introduce necessary conditions for a cellular automaton to be "universal", according to a precise notion of simulation ...

New Universality of Lyapunov Spectra in Hamiltonian Systems
, 1997 A new universality of Lyapunov spectra {\lambda_i} is shown for Hamiltonian systems. The universality appears in middle energy regime and is different from another universality which can be reproduced by random matrices in the following two points.

Azimuthal distributions of pions inside jets at RHIC [PDF]
, 2013 We evaluate the azimuthal asymmetries for the distributions of leading pions inside a jet, produced in high-energy proton-proton collisions, in kinematic configurations currently under active investigation at RHIC.

FEBS Letters, EarlyView.This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Molecular Oncology, EarlyView.Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...
