Here, we compare several measures largely used to characterize energy dissipation and kinetic-scale conversion in plasmas by means of a suite of kinetic numerical simulations describing both magnetic reconnection and decaying plasma turbulence. We differentiate between i) energy-based parameters, whose definition is related to energy transfer in a fluid description of the plasma, and ii) distribution function-based parameters, requiring knowledge of the particle velocity distribution function. Dissipation occurs close to regions of intense magnetic stresses. The distribution function-based measures show a broader width compared to energy-based proxies, suggesting that energy transfer is co-localized at coherent structures, but can affect the particle distribution function in wider regions. The effect of inter-particle collisions on these parameters is finally discussed.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Pezzi O.; Liang H.; Juno J.L.; Cassak P.A.; Vasconez C.L.; Sorriso-Valvo L.; Perrone D., Servidio S.; Roytershteyn V.; Tenbarge J.M.; Matthaeus W.H.<\/p>\n","protected":false},"featured_media":1294,"comment_status":"closed","ping_status":"open","template":"","meta":[],"product_cat":[709],"product_tag":[3659,4447],"class_list":["post-10598","product","type-product","status-publish","has-post-thumbnail","hentry","product_cat-proceedings-papers","product_tag-weakly-collisional-plasmas","product_tag-dissipation-measures","prodpage-style2"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product\/10598","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/comments?post=10598"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/media\/1294"}],"wp:attachment":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/media?parent=10598"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product_cat?post=10598"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product_tag?post=10598"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
