Reciprocal Symmetric and Origin of Quantum Statistics [PDF]
arXiv, 2007 Boltzmann's differential equation is replaced by the corresponding reciprocal symmetric finite difference equation. Finite difference translates discreteness of energy. Boltzmann's function, then, splits into two reciprocally related functions. One of them gives Planck's radiation relation and the other one gives the corresponding Fermi-Dirac relation.

Inter‐Layer Diffusion of Excitations in 2D Perovskites Revealed by Photoluminescence Reabsorption
Advanced Functional Materials, EarlyView.Inter‐layer diffusion of photoexcitations is monitored in thin films of the 2D perovskite (PEA)2PbI4 by tracking time‐dependent changes in photoluminescence spectra induced by photon reabsorption effects. A low out‐of‐plane excitation diffusion coefficient of 0.26 × 10−4 cm2 s−1 is determined through 1D diffusion modeling.

Modular Inverse and Reciprocity Formula [PDF]
arXiv, 2013 This paper proves a reciprocity formula for modular inverses for non-zero integers and demonstrates some applications of the reciprocity formula in calculating or verifying some modular inverses of specific forms, including the modular inverse of a Gaussian integer modulo another Gaussian integer.

To reciprocate or not to reciprocate: Exploring temporal qualities in reciprocal exchanges in networks [PDF]
, 2014 In this article, we sought to draw theoretical explanations of reciprocal exchanges in networks and how reciprocity is seen as the building block of network sustainability through employing a temporal perspective. The article’s main contribution was to provide fresh insights into how temporality, drawn upon Bergson’s philosophy, advanced the way we ...

Spin‐Selective Anisotropic Magnetoresistance Driven by Chirality in DNA
Advanced Functional Materials, EarlyView.It is shown that magnetoresistance (MR) measurements carried out as a function of angular dependence between the magnetic field and a chiral (DNA) interface provide a valuable new insight into the charge transport mechanism associated with the chiral‐induced spin selectivity (CISS) effect.

L'economia politica della reciprocità
Moneta e Credito, 2013 The work seeks to answer two questions. First, if the removal of trade barriers is in each countries own interest, why are negotiations based on the principle of reciprocity?

The Reciprocal Pascal Matrix [PDF]
arXiv, 2014 The reciprocal Pascal matrix is the Hadamard inverse of the symmetric Pascal matrix. We show that the ordinary matrix inverse of the reciprocal Pascal matrix has integer elements. The proof uses two factorizations of the matrix of super Catalan numbers.
