Hope And The Handiwork Of Varda: Celestial Signposts Of The Music’S Mending, Kristine Larsen May 2026

Hope And The Handiwork Of Varda: Celestial Signposts Of The Music’S Mending, Kristine Larsen

Journal of Tolkien Research

Varda, the Queen of the Valar, wields tremendous cosmological power in Tolkien’s legendarium. It is not without cause that Melkor fears her, as her power is literally written in the stars for all to see. Not only do her bright stars and constellations provide light against the darkness, but two of her creations – the Valacirca (Big Dipper) and Menelmacar (Orion) – are direct and intentional warning signs to Melkor of his unavoidable defeat in the Last Battle at the end of days. Indeed, Melkor’s capture by the armies of the Valar at the end of the First Age is …


Distributed Self-Control Of Dynamical Networks By Adaptive Link Weight Adjustments, Hiroki Sayama May 2026

Distributed Self-Control Of Dynamical Networks By Adaptive Link Weight Adjustments, Hiroki Sayama

Northeast Journal of Complex Systems (NEJCS)

Conventional control theory considers controlling the behavior of a dynamical system toward a desired state by injecting externally designed inputs into the system. Meanwhile, most complex systems exhibit self-organization through local information exchanges among individual dynamical components that are embedded within a complex network of interactions. The self-organizing dynamics of those systems are realized in a highly distributed manner using locally available information only, and therefore, their behaviors have not been discussed much from a control theoretic viewpoint. Meanwhile, adaptive networks, i.e., dynamical networks whose states and topologies coevolve at similar time scales, can offer a promising theoretical framework in …
