Edge Exchangeable Models for Interaction Networks [PDF]
Journal of the American Statistical Association, 2018 Many modern network datasets arise from processes of interactions in a population, such as phone calls, email exchanges, co-authorships, and professional collaborations. In such interaction networks, the edges comprise the fundamental statistical units, making a framework for edge-labeled networks more appropriate for statistical analysis.

Spin-Exchange Interaction in ZnO-based Quantum Wells [PDF]
, 2006 Wurtzitic ZnO/(Zn,Mg)O quantum wells grown along the (0001) direction permit unprecedented tunability of the short-range spin exchange interaction. In the context of large exciton binding energies and electron-hole exchange interaction in ZnO, this ...

Calculated magnetic exchange interactions in the van der Waals layered magnet CrSBr
New Journal of Physics, 2023 Intrinsic van der Waals materials layered magnets have attracted much attention, especially the air-stable semiconductor CrSBr. Herein, we carry out a comprehensive investigation of both bulk and monolayer CrSBr using the first-principles linear-response

Field Induced Slow Magnetic Relaxation in a Non Kramers Tb(III) Based Single Chain Magnet
Magnetochemistry, 2018 Herein, we report a novel Tb(III) single chain magnet with the chemical formulae [Tb(μ-OH2)(phen)(μ-OH)(nb)2]n by using 4-nitrobenzoic acid (Hnb) and 1,10-phenanthroline (phen) as ligand system. The single-crystal X-ray diffraction reveals that

Semiosis as a Source of Providing Empirical Phenomena with a New Type of Cohesion
Entropy, 2023 Embodying the indexical signs is vital to semiosis as a cohesive material agency mediating between consequents and antecedents. One unique factor of biology compared with standard physics and chemistry is the cohesion enabling the biological components ...
