    Remark a posteriory: this harmless comment (in three versions for the interested reader) was not accepted by The Journal of Chemical Physics. The reason was a dogget fight of a reviewer against the comment. I guess that he was one of the authors of the commented paper. It was a dirty story, with many false statements; and I did not understand it. Nevertheless, the interested reader should look to another comment to the same paper by:

    xx. Wolfgang Quapp, J.M.Bofill: Bei Phys. Rev. Research abgelehnt (2023):
    Comment: Catch-slip bonding, Pathway switching, and Singularities [Phys. Rev. Research 5, 023161 (2023)], paper by Barkan und Bruinsma.
    Preprint: download
    --- Der Comment wurde abgelehnt. Zuerst verzögerte der Editor die Begutachtung durch einen faulen Trick um ein Vierteljahr. Dann 'durften' die kritisierten Autoren begutachten; sie waren der Meinung, alles richtig gemacht zu haben. Der arrogante Editor lehnte daraufhin den Comment zum ersten mal ab. Der Einspruch, dass die kritisierten Autoren eventuell voreingenommen sein könnten, führte zu zwei regulären Reviews, von denen eines wieder klar dem kritisierten Paper den Vorrang gab. Daraufhin gab es die zweite Ablehnung. Nun starteten wir einen offiziellen Widerspruch bei PRR, der aber dann endgültig abgelehnt wurde (3.Ablehnung!).
    In Summe: 1 Editor, 3 Gutachter und 2 kritisierte Autoren, wahrscheinlich alle 6 Physiker, ignorieren schwere mathematische Fehler in einer Arbeit.
    By the way, das ist ein zweiter Kommentar von uns, der bei PR schnöde, mit einer sehr skurrilen Begründung, abgelehnt wurde.
    Wo ist die wissenschaftliche Ethik hinverschwunden? PR hat mal damit geworben, das hier A.Einstein veröffentlicht hat.
    Den vergleichsweise kurzen Kommentar haben wir daraufhin erweitert zu einem vollen (und am Ende ziemlich langen) Paper zu Catch Bonds. Vergleiche Punkte xxx, 120 und 121. hiernach.

    xxx. Wolfgang Quapp, J.M.Bofill: Foundations (2023) zurückgezogen / withdrawn
    Altering Selectivity in the Tug-of-War Mechanism by Mechanochemistry - with an Explanation of Catch Bond Behavior
    --- Die Arbeit wurde bei 'Foundations' von MDPI eingereicht. Dort sind offenbar 4 Reviews notwendig. Drei waren (in angemessener Zeit) positiv, aber der 4.Reviewer (sehr wahrscheinlich ein B von [B und B]) war extrem bösartig, und er suchte den Editionsprozess extrem zu verzögern. Wir hofften, dass die Editoren dies selbst erkennen würden. Das war aber nicht der Fall. Wir zogen darauf hin die Arbeit zurück, vor einer zu erwartenden Ablehnung in ferner Zukunft. (Vergleiche unten, No.120, wo das Paper dann noch verbessert erscheinen konnte, und auch No.(121.))

    The reasoning is: ".. unfortunately, our Editorial Board has determined that it does not contribute substantially to the discussion of the original article and therefore has declined to accept it for publication."
    Note: the reviewers do not discuss deep errors of the paper. They only reject weak side-remarks of the comment. (A usual practice in questionable reviews.)
    The journal PNAS seems not to be interested in scientific truth; probably only the money for a page charge is it what counts. (They demanded a page charge for the comment indeed which we where not willing to pay.) And they 'needed' 138 days for the rejection of this one-page comment. In this time they demanded many crazy formal changes; is it the usual psycho-terror for a comment?
    -------------------------------------------
    121.b) For the friends of B and B, and for their mild reviewers, here we give additionally a long version of the comment which was too long for the letter-version of PNAS comments. It contains some more errors of the commented paper:

    Wieder ein Kommentar zurückgewiesen: Es wird die Norm, dass Journale einen Kommentar verhindern. (Wie in der Politik, die Wahrheit ist nicht mehr interessant.)
    Diesmal ging es so: Der Editor hat zwei Reviewer beauftragt, die keine Ahnung von der Theorie der Newtontrajektorien hatten. Man erkannte das an ihren Fragen und Forderungen für das erste 2-Seiten-Paper. Im 1.Antwortbrief haben wir alle diese Fragen ausführlich besprochen, aber da inhaltlich alles altbekanntes Zeug war, nicht viel im Kommentar geändert. Dies passte aber dem Editor nicht, der alle Fragen der Reviewer im Kommentar beantwortet haben wollte. So ist, uber eine Zwischenstufe, vorliegender Artikel entstanden. Dieser war aber einem der Reviewer, und einem weiteren 'Schiedsrichter' nun zu lang. Einen Übersichtsartikel wollten sie auch nicht haben, sagen sie ... Auf die Idee, den Anfangskommentar zu verwenden, kam Niemand.
    Aber immerhin, 4 hochqualifizierte Scientists (the best and brightest) haben sich nun näher mit den Newtontrajektorien beschäftigt. Eventuell hilft es dieser Theorie.

    Beitrag: download
    Schwindel und Ohnmachten waren die Folge eines Herzschrittmachers, der nicht richtig eingestellt war. Die Lösung lag im Rüttel-Sensor. Kommentar von Prof.Dr.med. Andreas Schuchert, Friedrich-Ebert-Krankenhaus Neumünster
    Schlagwörter: Herzschrittmacher, Betriebsweise DDD-R, Rüttelsensor (wahre Funktion), Frequenzanpassung (Euphemismus)
    Nachspiel:
    Die falsche Einstellung des Herzschrittmachers habe ich als Kunstfehler eingeklagt. Es zog sich sehr lange hin: Die Gegenseite behauptete alles richtig gemacht zu haben, unterstellte mir sogar eine nicht vorhandene Erkrankung, und ein sogenannter Gutachter bestätigte es. Die Gerichte glauben dem Gutachter.
    Hier meine Zusammenstellung vom Mai 2020.
