Upper critical fields of quasi-low-dimensional superconductors with coexisting singlet and triplet pairing interactions in parallel magnetic fields [PDF]

open access: yes, 2000
Quasi-low-dimensional type II superconductors in parallel magnetic fields are studied when singlet pairing interactions and relatively weak triplet pairing interactions coexist.

Paired Comparisons for Paired Characteristics

open access: yesThe Annals of Mathematical Statistics, 1968
The present investigation is concerned with the proposal and study of a class of nonparametric paired comparison tests for the hypothesis of no differences among several objects with respect to a pair of characteristics.

Why pair? Evidence of aggregative mating in a socially monogamous marine fish (Siganus doliatus, Siganidae) [PDF]

open access: yesRoyal Society Open Science, 2015
Many species live in stable pairs, usually to breed and raise offspring together, but this cannot be assumed. Establishing whether pairing is based on mating, or an alternative cooperative advantage, can be difficult, especially where species show no ...

A Survey of Wearable Devices Pairing Based on Biometric Signals

open access: yesIEEE Access, 2023
With the rapid growth of wearable devices, more applications require direct communication between wearable devices. To secure the communication between wearable devices, various pairing protocols have been proposed to generate common keys for encrypting ...

Strong magnetic field enhancement of spin triplet pairing arising from coexisting $2k_F$ spin and $2k_F$ charge fluctuations [PDF]

open access: yes, 2007
We study the effect of the magnetic field (Zeeman splitting) on the triplet pairing. We show generally that the enhancement of spin triplet pairing mediated by coexisting $2k_F$ spin and $2k_F$ charge fluctuations can be much larger than in the case of ...

Paired ions: Dipolar pairs as subset of diffusion pairs [PDF]

open access: yesProceedings of the National Academy of Sciences, 1978
Previous models for which theories of electrolytic conductance have been developed are reviewed. Discrepancies between theoretically derived values of parameters and parameters characteristic of real physical systems suggested the following revised model. Ions are counted as diffusion pairs if their center-to-center distance r

Translational-Invariant Bipolarons and Superconductivity

open access: yesCondensed Matter, 2020

Pairing in two-dimensional boson-fermion mixtures [PDF]

open access: yes, 2004
The possibilities of pairing in two-dimensional boson-fermion mixtures are carefully analyzed. It is shown that the boson-induced attraction between two identical fermions dominates the p-wave pairing at low density.

Nilpotent Pairs, Dual Pairs, and Sheets [PDF]

open access: yesJournal of Algebra, 2001
Recently, V.Ginzburg introduced the notion of a principal nilpotent pair (= pn-pair) in a semisimple Lie algebra {\frak g}. It is a double counterpart of the notion of a regular nilpotent element. A pair (e_1,e_2) of commuting nilpotent elements is called a pn-pair, if the dimension of their simultaneous centralizer is equal to the rank of {\frak g ...
