For the polished surface (steady state) we study the probability distribution of slips and find an exponential behavior for all the physically relevant asperity interaction-distance thresholds. In addition, we characterize the time evolution of the sample by its spatial fractal dimension and by its entropy content. Starting from an unpolished surface, the entropy decreases during the Robin Hood process, until it reaches a plateau; thereafter the system fluctuates above the critical height. This validates the notion that friction increases information in the neighborhood of the contacting surface at the expense of losing information in remote regions. We explain the practical relevance of these results for engineering surface processing such as honing.<\/jats:p>","DOI":"10.3390\/e12030480","type":"journal-article","created":{"date-parts":[[2010,3,14]],"date-time":"2010-03-14T13:26:04Z","timestamp":1268573164000},"page":"480-489","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Negentropy Generation and Fractality in the Dry Friction of Polished Surfaces"],"prefix":"10.3390","volume":"12","author":[{"given":"Pablo","family":"Fleurquin","sequence":"first","affiliation":[{"name":"Instituto de F\u00edsica, Facultad de Ciencias, Universidad de la Rep\u00fablica, Montevideo, Uruguay"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hugo","family":"Fort","sequence":"additional","affiliation":[{"name":"Instituto de F\u00edsica, Facultad de Ciencias, Universidad de la Rep\u00fablica, Montevideo, Uruguay"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mordechai","family":"Kornbluth","sequence":"additional","affiliation":[{"name":"Department of Physics, Yeshiva University, New York, NY 10033, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roman","family":"Sandler","sequence":"additional","affiliation":[{"name":"Department of Physics, Yeshiva University, New York, NY 10033, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mordecai","family":"Segall","sequence":"additional","affiliation":[{"name":"Department of Physics, Yeshiva University, New York, NY 10033, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fredy","family":"Zypman","sequence":"additional","affiliation":[{"name":"Department of Physics, Yeshiva University, New York, NY 10033, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2010,3,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1607","DOI":"10.1098\/rsta.2009.0009","article-title":"Thermodynamics of surface degradation, self-organization and self-healing for biomimetic surfaces","volume":"367","author":"Nosonovsky","year":"2009","journal-title":"Phil.
