Dimensionless ratios: Characteristics of quantum liquids and their phase transitions

Dimensionless ratios of physical properties can characterize low-temperature phases in a wide variety of materials. As such, the Wilson ratio (WR), the Kadowaki-Woods ratio, and the Wiedemann-Franz law capture essential features of Fermi liquids in metals, heavy fermions, etc. Here we prove that the phases of many-body interacting multicomponent quantum liquids in one dimension (1D) can be described by WRs based on the compressibility, susceptibility, and specific heat associated with each component. These WRs arise due to additivity rules within subsystems reminiscent of the rules for multiresistor networks in series and parallel—a novel and useful characteristic of multicomponent Tomonaga-Luttinger liquids (TLL) independent of microscopic details of the systems. Using experimentally realized multispecies cold atomic gases as examples, we prove that the Wilson ratios uniquely identify phases of TLL, while providing universal scaling relations at the boundaries between phases. Their values within a phase are solely determined by the stiffnesses and sound velocities of subsystems and identify the internal degrees of freedom of said phase such as its spin degeneracy. This finding can be directly applied to a wide range of 1D many-body systems and reveals deep physical insights into recent experimental measurements of the universal thermodynamics in ultracold atoms and spins.

Chronic care manages long-term, progressive conditions, while acute care addresses short-term conditions. Chronic conditions increasingly strain health systems, which are often unprepared for these demands. This study examines the burden of conditions requiring acute versus chronic care, including sequelae. Conditions and sequelae from the Global Burden of Diseases Study 2019 were classified into acute or chronic care categories. Data were analysed by age, sex, and socio-demographic index, presenting total numbers and contributions to burden metrics such as Disability-Adjusted Life Years (DALYs), Years Lived with Disability (YLD), and Years of Life Lost (YLL). Approximately 68% of DALYs were attributed to chronic care, while 27% were due to acute care. Chronic care needs increased with age, representing 86% of YLDs and 71% of YLLs, and accounting for 93% of YLDs from sequelae. These findings highlight that chronic care needs far exceed acute care needs globally, necessitating health systems to adapt accordingly. © 2025. The Author(s).

It is effective to ensure the credibility of program to monitor the real-time status in the whole process when the program is been executed. Aiming at the problem of high convexity of feature extracting and interaction between false positive and false negative rate in current study, this paper proposed one kind of program behaviour model based on the dependencies. It constituted variable-length system call sequences according to the sifting and relevance analysing of system calls generated from running program. We can get the feature sequence through layered analysing, aggregation and simplification. Experiments on the selected samples show that the model is feasible and has better control on false positive and false negative rate.

This Letter describes the observation of the light-by-light scattering process, γγ→γγ, in Pb+Pb collisions at sNN=5.02 TeV. The analysis is conducted using a data sample corresponding to an integrated luminosity of 1.73 nb−1, collected in November 2018 by the ATLAS experiment at the LHC. Light-by-light scattering candidates are selected in events with two photons produced exclusively, each with transverse energy ETγ>3 GeV and pseudorapidity |ηγ|<2.4, diphoton invariant mass above 6 GeV, and small diphoton transverse momentum and acoplanarity. After applying all selection criteria, 59 candidate events are observed for a background expectation of 12±3 events. The observed excess of events over the expected background has a significance of 8.2 standard deviations. The measured fiducial cross section is 78±13(stat)±7(syst)±3(lumi) nb.

Vertex-centered finite volume schemes of any order over quadrilateral meshes for elliptic boundary value problems

Numerische Mathematik 2015年第2期130卷 363-393页

作者： Zhang, Zhimin Zou, Qingsong Beijing Computational Science Research Center Beijing 100084 China Department of Mathematics Wayne State University Detroit 48202 MI United States College of Mathematics and Scientific Computing Guangdong Province Key Laboratory of Computational Science Sun Yat-sen University Guangzhou 510275 China

A family of any order finite volume (FV) schemes over quadrilateral meshes is analyzed under the framework of Petrov–Galerkin method. By constructing a special mapping from the trial space to the test space, a unified proof for the inf–sup condition of any order FV schemes is provided under a weak condition that the underlying mesh is an (Formula presented.),γ>0 parallelogram mesh. The optimal convergence rate of FV solutions is then obtained with well-known techniques. © 2014, Springer-Verlag Berlin Heidelberg.
