An effective formalism is developed to handle decaying two-state systems. Herewith, observables of such systems can be described by a single operator in the Heisenberg picture. This allows for using the usual framework in quantum information theory and, hence, to enlighten the quantum features of such systems compared to non-decaying systems. We apply it to systems in high energy physics, i.e. to oscillating meson–antimeson systems. In particular, we discuss the entropic Heisenberg uncertainty relation for observables measured at different times at (...) accelerator facilities including the effect of $\mathcal{CP}$ violation, i.e. the imbalance of matter and antimatter. An operator-form of Bell inequalities for systems in high energy physics is presented, i.e. a Bell-witness operator, which allows for simple analysis of unstable systems. (shrink)
Collapse models predict the spontaneous collapse of the wave function, in order to avoid the emergence of macroscopic superpositions. In their mass-dependent formulation, they claim that the collapse of any system’s wave function depends on its mass. Neutral K, D, B mesons are oscillating systems that are given by Nature as superposition of two distinct mass eigenstates. Thus they are unique laboratory for testing collapse models that are sensitive to the mass. In this paper we derive—for the single mesons and (...) bipartite entangled mesons—the effect of the mass-proportional CSL (Continuous Spontaneous Localization) collapse model on the dynamics on neutral mesons. We compare the theoretical prediction with experimental data from different accelerator facilities. (shrink)
Functional diversity holds the promise of understanding ecosystems in ways unattainable by taxonomic diversity studies. Underlying this promise is the intuition that investigating the diversity of what organisms actually do—i.e. their functional traits—within ecosystems will generate more reliable insights into the ways these ecosystems behave, compared to considering only species diversity. But this promise also rests on several conceptual and methodological—i.e. epistemic—assumptions that cut across various theories and domains of ecology. These assumptions should be clearly addressed, notably for the sake (...) of an effective comparison and integration across domains, and for assessing whether or not to use functional diversity approaches for developing ecological management strategies. The objective of this contribution is to identify and critically analyze the most salient of these assumptions. To this aim, we provide an “epistemic roadmap” that pinpoints these assumptions along a set of historical, conceptual, empirical, theoretical, and normative dimensions. (shrink)
A case study of growers conception of irrigation strategies indicates that pot plant growers in Scandinavia base their management approaches on experientially based art. The study also indicates that there is a gap between experientially based art and available greenhouse technology. In order to standardize production and produce quality, both the growerâs experience and available technology should be taken into account. In order to achieve this, the present study proposes to arrange reflection on reflection in action with a group of (...) growers by means of the dialogue seminar method. The concept of reflection on reflection in action is novel to horticultural practice. Therefore, we suggest future inter- and multidisciplinary research within this domain. (shrink)
We show that Stoffregen & Bardy's arguments against the assumption of separately functioning senses have more historical antecedents than they give credit for, and that multimodal functioning does not require this assumption. What is needed is evidence that biological organisms are indeed detecting and acting upon information in a multimodal (or global) array.
Das Buch geht der Frage nach, wie Metaphern in Sehflächen verankert sind. Um eine fundierte Antwort geben zu können, setzt sich die Verfasserin mit einschlägigen sprachlichen, kognitiven und visuellen Metapherntheorien auseinander und entwickelt ein Modell speziell zur Analyse zeichensystemübergreifender Strukturmetaphern. Das Modell wird mit dem Fokus auf Zeitmetaphern an ausgwählten Werbeanzeigen und Kunstwerken erprobt. Da Zeit in Text-Bild-Gefügen zudem in Form sprachlich determinierter bildlicher Orientierungsmetaphern codiert ist, werden auch diese in bestimmten Flächen- und Farbgestaltungen identifiziert. Ferner werden beide Metaphernarten im (...) dichtesten Konglomerat der ikonischen Typografie und Kalligrafie aufgespürt. Sämtliche Analysen und die daraus hervorgehenden Deutungen der Sehflächen repräsentieren den gegenwärtigen Zeitbegriff in unserer Gesellschaft, welcher über zwei feldtheoretische Karten aufgerissen wird.
