Photosynthetic and transpiration (E) rates, stomatal conductance, and leaf nitrogen content were surveyed for Myrica gale var. tomentosa, a N2-fixing wetland shrub, Betula platyphylla var. japonica, and Rhododendron japonicum in Ozegahara moor, an oligotrophic moor in Central Japan. Net photosynthetic rate saturated with irradiance (Pmax) of M. gale was 15.2-16.5 μmol(CO2) m-2 s-1, higher than those of the other species throughout the growing season. Pmax was positively correlated with leaf N content among the three species. The large leaf N content in M. gale was due to N2-fixation in root nodules. In a comparison of M. gale in two habitats, Pmax, leaf N content, and root nodule development were larger in the wetter habitat. M. gale showed high E and no midday depression of Pmax even under high irradiance and large vapour pressure deficit between leaves and ambient air on a midsummer day. These traits of photosynthesis and water relations were associated with the dominance of this shrub in wetter sites such as stream sides and hollows. and K, Maeda ... [et al.].

This study, in the form of an essay or first draft of opening remarks delivered at an international conference on Culture in the Age of Enlightenment, presents one of many possible models for the conceptualization of the Enlightenment in the Czech Lands. Here Enlightenment is conceived as a process whereby ‘knowledge’ (information) is disseminated and gradually democratized and information networks are expanded. This conception draws primarily on theories of vernacularization and cultural transfer. In view of the directional dynamic, we have focussed mainly on ‘unidirectional’ flow in the sense of dispersal from (informational/cultural) centres to the (informational/cultural) periphery – both socioeconomically (transfer to lower social classes) and geographically (transfer to rural areas remote from major urban and educational centres). In this model, the process of vernacularization and democratization of knowledge was divided into three periods: the early formation of educated elites; the ‘acculturation’ of the middle classes; and the extension of information networks to the petty intelligentsia – and through them to the wider rural population. This last phase, carried out as part of a ‘programme’ of popular enlightenment around the turn of the 19th century, more or less coincided, in the theory Miroslav Hroch, with the first and second phases of the Czech National Revival and relied on the same media (Czech-language newspapers, ‘popular’ literature) and authors (Kramerius, Tomsa, Rulík, et al.)
Nobel Lecture, presented on December 8, 2016, at Aula Magna, Stockholm University. This article describes the history and background of three discoveries cited in this Nobel Prize: The "TKNN" topological formula for the integer quantum Hall effect found by David Thouless and collaborators, the Chern insulator of quantum anomalous Hall effect, and its role in the later discovery of time-reversal invariant topological insulators, and the unexpected topological spin-liquid state of the spin-1 quantum antiferromagnetic chain, which provided an initial example of topological quantum matter. This article summarizes how these early beginnings have led to the exciting, and currently extremely active, field of "topological matter"., F. Duncan M. Haldane ; přeložil Ivan Gregora ; foto A.
