The ground states of hidden-charm tetraquarks and their radial excitations
European Physical Journal C: Particles and FieldsInspired by the great progress in the observations of charmonium-like states in recent years, we perform a systematic analysis about the ground states and the first radially excited states of $$qc\bar{q}\bar{c}$$ q c q ¯ c ¯ (q = u/d and s) tetraquark ...

Reducing multi-dimensional information into a 1-d histogram
, 2009 We present two methods for reducing multidimensional information to one dimension for ease of understand or analysis while maintaining statistical power. While not new, dimensional reduction is not greatly used in high-energy physics and has applications

Advanced Engineering Materials, EarlyView., 2023 A novel method for tracking structural changes in gels using widely accessible microcomputed tomography is presented and validated for various hydro‐, alco‐, and aerogels. The core idea of the method is to track positions of micrometer‐sized tracer particles entrapped in the gel and relate them to the density of the gel network.

Collaborative yet independent: Information practices in the physical sciences [PDF]
, 2011 In many ways, the physical sciences are at the forefront of using digital tools and methods to work with information and data. However, the fields and disciplines that make up the physical sciences are by no means uniform, and physical scientists find ...

An explanation of infrared catastrophe of 1/f power spectra [PDF]
arXiv, 2003 Chen [1] builds the intrinsic link between the 1/f power spectra and the acoustic frequency power law dissipation and, accordingly, presents two explanations of the so-called infrared catastrophe of the 1/f power spectra. This note is an immediate follow-up.

Power of a determinant with two physical applications [PDF]
International Journal of Mathematics and Mathematical Sciences, 1999 An expression for the kth power of an n × n determinant in n2 indeterminates (zij) is given as a sum of monomials. Two applications of this expression are given: the first is the Regge generating function for the Clebsch‐Gordan coefficients of the unitary group SU(2), noting also the relation to the 3 F2 hypergeometric series; the second is to the ...

The unitary theory of the electrical powers [PDF]
Annals of the University of Craiova, Electrical Engineering series
No30, 2006, pg.21-26, 2009 General physics approach is applied to analysis of power components in electrical systems under sinusoidal and non-sinusoidal conditions. Physical essence of active, reactive and distorting powers are determinate. It is shown that the all three powers are the different aspects of the same physical phenomenon: mechanical action per time of Coulomb ...

A note on cohering power and de-cohering power [PDF]
Quant. Inf. Comp. 13&14,1206-1220 (2017), 2016 Cohering power and de-cohering power have recently been proposed to quantify the ability of a quantum operation to produce and erase coherence respectively. In this paper, we investigate the properties of cohering power and de-cohering power. First, we prove the equivalence between two different kinds of cohering power for any quantum operation on ...
