(Repatriat)Able Bones: Tales of Ambiguity in the Repatriation Nexus
On_Culture, 2021 European museums (of ethnography) and the material culture under their custody — a large portion of which was collected by the soldiers, explorers, and professional looters of the colonial era — are increasingly confronted by formerly colonized countries

Reciprocity in the Hecke Groups [PDF]
arXiv, 2023 An element $g$ in a group $G$ is called \emph{reciprocal} if there exists $h \in G$ such that $g^{-1}=hgh^{-1}$. The reciprocal elements are also known as `real elements' or `reversible elements' in the literature. We classify the reciprocal elements and parametrize the reciprocal classes in the Hecke groups $\Gamma_p$ for $p\geq 3$. This generalizes a

Model of Wikipedia growth based on information exchange via reciprocal arcs [PDF]
EPL 93 (2011) 58005, 2009 We show how reciprocal arcs significantly influence the structural organization of Wikipedias, online encyclopedias. It is shown that random addition of reciprocal arcs in the static network cannot explain the observed reciprocity of Wikipedias. A model of Wikipedia growth based on preferential attachment and on information exchange via reciprocal arcs

Massive MIMO Performance With Imperfect Channel Reciprocity and Channel Estimation Error [PDF]
IEEE Transactions on Communications, 2017 Channel reciprocity in time-division duplexing (TDD) massive multiple-input multiple-output (MIMO) systems can be exploited to reduce the overhead required for the acquisition of channel state information (CSI).

Citations and gender diversity in reciprocal acknowledgement networks [PDF]
arXiv, 2021 Acknowledgements in scientific articles suggest not only gratitude, but also the interactions among scientists. In this study, we examine the acknowledgement interactions employing data from open-access journals (PLOS series). We built an acknowledgement network where the nodes represent authors and acknowledged people, while the links correspond to ...

Multidimensional Ehrhart Reciprocity [PDF]
, 2002 In a previous paper (El. J. Combin. 6 (1999), R37), the author generalized Ehrhart's idea of counting lattice points in dilated rational polytopes: Given a rational polytope, that is, a polytope with rational vertices, we use its description as the ...

Reciprocity and alignment: quantifying coupling in dynamic interactions
Royal Society Open Science, 2021 Recent accounts of social cognition focus on how we do things together, suggesting that becoming aligned relies on a reciprocal exchange of information.

FEBS Letters, EarlyView.Spot‐14 and Spot‐14R play distinct roles in regulating metabolism in brown and beige adipocytes. While both influence lipid and glucose pathways, Spot‐14 uniquely controls thermogenic gene expression. This dual regulation balances energy storage and heat production, highlighting potential therapeutic targets for obesity and metabolic disorders. Spot 14

Reciprocity in Social Networks with Capacity Constraints
, 2015 Directed links -- representing asymmetric social ties or interactions (e.g., "follower-followee") -- arise naturally in many social networks and other complex networks, giving rise to directed graphs (or digraphs) as basic topological models for these ...
