It is demonstrated that the virtual dynamics case that we proposed for the Langevin equation [J. Chem. Phys. 147, 184104 （2017）] in principle exists in other types of stochastic thermostats as well. The recommended ＂middle＂ scheme [J. Chem. Phys. 147, 034109 （2017）] of the Andersen thermostat is investigated as an example. As shown by both analytic and numerical results, while the real and virtual dynamics cases approach the same plateau of the characteristic correlation time in the high collision frequency limit, the accuracy and efficiency of sampling are relatively insensitive to the value of the collision frequency in a broad range. After we compare the behaviors of the Andersen thermostat to those of Langevin dynamics, a heuristic schematic representation thermostatting processes with molecular is proposed for understanding efficient stochastic dynamics.展开更多

The dialectics of concrete totality implies a marxistic critique of the ethical and juristic universalism, in the context of the ＂positive＂ side of globalization and political unilateralism, as a concrete, militant, hegemonistic, post-colonial, and neo-imperial practice （Apel, Habermas, Chomsky, Zinoviev）; globalization as totali（tari）zation, the ＂last man,＂ the ＂end of history,＂ and the ＂end＂ of dialectics in its neo-liberal, eschatological, empty ideological ＂realization＂ （Hegel, Marx, Fukuyama, Arendt）; the totality of the （invariable） being as a pseudo-concrete and pseudo-dialectical ontologistic speculation （Heidegger）： A ＂return＂ to a concrete history and a return of the ＂positive＂ dialectics as a critical awareness, mind, and method in the discourse ＂game＂ of human＇s cognitive, creative, and practical powers. The assumption of Kosik＇s humanism is a synchrony of nature and history in the ＂absolute＂ totality of human＇s concrete existence （Lukacs, Goldmann, Adorno, Sartre, Kosik）.展开更多

However, no knowledge about the actual number of vaccinations has been available. Based on previous preliminary studies in slaughterhouses and among horse owners, it was suspected that vaccination recommendations are not always followed. The aims were to investigate vaccination status against equine influenza among Finnish racehorses in regional competitions. Vaccination status was investigated： （1） by utilizing database vaccination information of show jumping and dressage horses and （2） by carrying out a survey among horse industry experts. A total of 400 horses were selected at the beginning of the Finnish competition season in 2012 and five experts （key persons） were invited to a repeated survey implemented by Delphi techniques. Overall, 50%-100% of horses were properly vaccinated depending on the source available. Thirty-four percent （34%） of the horses had the competition license but no vaccination markings in the database. Differences between types of competition （show jumping and dressage） and between Southern and Northern parts of Finland were found. Vaccinations of show jumping horses were registered more often than vaccinations of dressage horses. Ninety percent （90%） of unvaccinated horses in the database were eight years or older. It can be concluded that equine influenza vaccination registry coverage among racehorses in Finland is incomplete. This poses a risk of misunderstanding, and the growing responsibility of competition organizers.展开更多
