Diagenesis of clay minerals and K-bentonites in Late Permian/Early Triassic sediments of the Sichuan Basin (Chaotian section, Central China).

2014

10 pages; International audience; Detailed clay mineralogical analyses were carried out on Late Permian/Early Triassic carbonate sediments exposed on the Chaotian section (Sichuan Basin, Central China). The clay assemblages are dominantly composed of illite in platform carbonates and clay seams, and illite-smectite mixed-layers (I/S) in tuff layers (K-bentonites) intercalated in the carbonate succession. Detrital and authigenic volcanogenic clay minerals have been partially replaced through illitisation processes during burial, raising questions about diagenetic effects. The precise determination of I/S occurring in K-bentonites shows that the sediments reached a temperature of about 180 °C…

Using discourse markers to negotiate epistemic stance: A view from situated language use

2021

Abstract In this paper, I analyse the usage of a discourse marker =mari, belonging to the epistemic paradigm attested in Upper Napo Kichwa (Quechuan, Ecuador). I show that the use of =mari indicates that the information is known well to the speaker, but also to some extent familiar to the addressee. In situated language use, the marker contributes to creating a knowing epistemic stance of the speaker. The analysis presented here is based on a 13-h documentary corpus of interactive Upper Napo Kichwa discourse, recorded on audio and video. For the purpose of the paper, the relevant utterances are analysed in their broad interactional context, including not only the surrounding text, but also …

Long-term impact of 19 years' farmyard manure or sewage sludge application on the structure, diversity and density of the protocatechuate-degrading b…

2012

International audience; Impact of long-term biosolids application on soil-living micro-organisms key players of ecosystemic services is scarcely reported. Here, the impact of the 19 year-long application of farmyard manure (FM) and sewage sludge (SS) organic fertilisation regimes on the protocatechuate-degrading bacterial (pca) community was estimated by comparison to a mineral fertilisation regime (U). The structure, diversity and density of the pca community were determined using pcaH, a gene encoding the protocatechuate 3,4-dioxygenase. Ten years after the last application, the structure of the pca community in soils amended with 55100 (100 t/ha/2 years) and to a lesser extent with FM (1…

Hidden and self-excited attractors in radiophysical and biophysical models

2017

One of the central tasks of investigation of dynamical systems is the problem of analysis of the steady (limiting) behavior of the system after the completion of transient processes, i.e., the problem of localization and analysis of attractors (bounded sets of states of the system to which the system tends after transient processes from close initial states). Transition of the system with initial conditions from the vicinity of stationary state to an attractor corresponds to the case of a self-excited attractor. However, there exist attractors of another type: hidden attractors are attractors with the basin of attraction which does not have intersection with a small neighborhoods of any equ…

Analytical-numerical methods for investigation of hidden oscillations in nonlinear control systems

2011

The method of harmonic linearization, numerical methods, and the applied bifurcation the- ory together discover new opportunities for analysis of oscillations of control systems. In the present survey analytical-numerical algorithms for hidden oscillation localization are discussed. Examples of hidden attrac- tor localization in Chua's circuit and counterexamples construction to Aizerman's conjecture and Kalman's conjecture are considered.

Displaced desires : the dislocated self and melancholic desire in Chuang Hua's Crossings and Fae Myenne Ng's Steer toward rock

2015

This essay investigates two aesthetically innovative Chinese American prose narratives, Crossings (1968) by Chuang Hua and Steer Toward Rock (2008) by Fae Myenne Ng, which have so far inspired relatively few scholarly readings. Although published forty years apart, both texts convey a melancholic image of displaced desires—loved ones who are lost, beyond reach, or unresponsive—that is echoed by their complex narrative structure and rich stylistic repertoire. Drawing from the psychoanalytically informed notion of racial melancholia, this essay argues that in Chuang’s Crossings and in Ng’s Steer Toward Rock the dynamics of melancholia manifest most prominently in the ways their dislocated cha…
