Birds hunting rodents: Two cases from tropical forests of Southern Vietnam
We describe two previously unknown cases of birds hunting rodents in tropical forests of Southern Vietnam. Number of belly-banded squirrels ( Callosciurus flavimanus ), caught in wire traps, shows a strong correlation with the number of crested serpent eagles ( Spilornis cheela ). Oriental pied hornbills ( Anthracoceros albirostris ) hunt red spiny rats ( Maxomys surifer ) over elevated areas of tropical forest
Some methodological foundations for elaboration of the modern strategies of ecological thinking based on the theoretical biology and on the theory of complex adaptive systems статье are under review in the article. Ecology, being a science of interaction of living organisms and their communities with environment, goes far beyond its primary frames of the biological knowledge and becomes a nodal discipline from which vectors of perspective interdisciplinary synthesis of knowledge diverge. The ecological approach turns to be fruitful in social and humanitarian researches. Ecology of action, ecology of mind, ecology of life, of cognition and of creativity, ecology of thoughts and words, ecology of ideas, ecology of communication and ecology of management – all these conceptual attitudes give evidence of audacious integration of the ecological thinking in wide spheres of the humanitarian and social knowledge, where it gives opportunities for some fresh approaches. The concept of Umwelt coined by Jakob von Uexküll in 1909 and his study of Umwelt (Umweltslehre) are of great significance for the development of the modern ecological universalism and for elaboration of strategic imperatives of the ecological thinking. The concept of Umwelt as a specific environment to which any biological species or its separate individual is adapted and which is constructed by it allows us to elaborate a real interdisciplinary platform for development of the theory of ecology, for holding a reasonable position in discussions about sustainable development and sustainable futures as well as about the role of education for sustainable development of the world.
This collection of papers comprises materials contributed for discussions at three international conferences held at the Institute for Far Eastern Studies, The Russian Academy of Sciences from 2010 through 2012. The collection consists of six sections covering the main areas of Vietnamese studies and touching upon various aspects of Vietnam’s internal and foreign policies as well as social and cultural life in the country during its long history.
Nowadays, the NearNorth of Russia undergoes a fateful epoch. The processes of destruction of the old world order in economic, social and cultural relations is not only continuing, but increasing its pace. The omnipresent destruction is manifested through the depopulation of villages and small towns, further decline in agricultural production, "consolidation" (actually closing) of educational institutions and health care centers, and the degradation of infrastructure. The compressed social space of the Middle North of Russia is shrinking in concentric circles around the regional centers, increasing the vastness of social vacuum and the white space, with the latter being gradually occupied by the mutating natural forms. In addition, yet another (opposite) trend can be identified. It is associated with the escalation of migration amongst the dwellers of the large cities, especially megalopolises, to rural areas.
Extensive development of Russian cities, especially Moscow and St. Petersburg, has revealed serious social problems that had previously not been fully taken into account. In particular, the rapid escalation and exacerbation of social problems determine the quality of life in cities. From one perspective, Moscow and St. Petersburg are represented as thriving metropolises possessing a whole set of such social attractors as rich and comfortable residential buildings, shopping malls with international brands, best restaurants, medical facilities and other requisites of the upper classes. However, parallel to these features, the quality of life in metropolitan areas is determined by such parameters as the deteriorating environmental conditions, increase in street (and other types of) crime, unsolvable traffic conditions which reduce inner-city mobility to a minimum, and the decline of anti-terrorist security.
In the Middle North of Russia, especially in the Kostroma region, one particular trend became evident: there has been a transition from the seasonal migration to dachas towards the ‘settled’ migration related not only to the summer recreation, but also to the industrial activity in the framework of modern technologies. Specifically, modern forms of labor in the field of information technology were initially (and still remain to be) exterritorial in nature. Those working with data tend to be indifferent to the location of their job – what is important to them is a point of connection to the network and a portal for entry into hyperspace.
This collection includes materials presented for discussion during three theoretical and practical conferences held at the Institute for Far Eastern Studies, the Russian Academy of Sciences, in 2013 through 2015 and published in Russian under common title of the Vietnam Studies in Russia. The papers in this title were selected among those submitted by Russian scholars only and published in issues 4 through 6 of the Vietnam Studies. It aims at acquainting foreign readers and researchers with current state of and case studies on Vietnam in Russia. The authors of presented topics are fulltime employees in major research centers of Russia, such as academic institutions, first of all the Centre for Vietnam and ASEAN studies, IFES RAS, and university centers in Moscow, St. Petersburg and Vladivostok. The collection consists of six subject sections covering the main areas of research and touching upon various realms of Vietnam's internal and foreign policies, social and cultural processes in that country. Part one includes papers discussing the current trends in relations between Russia / USSR and Vietnam. Part two analyzes political situation in Vietnam and its challenges in the region. Part three looks at Vietnam's socio-economic development under the impact of renovation reforms and market economy building. Part four highlights different episodes of Vietnam's history, and Part five represents studies in cultural area. Part six consists of topics on Vietnamese linguistics and literature. The original papers in this collection rely on a wide range of sources and documents, and reflect their authors' own findings. The authors' views do not necessarily represent those of the collection compilers. This collection is the second of its kind in the Russian Federation and is intended for distribution abroad. Volume One was edited by IFES RAS and published by Forum Publishing House in 2014.
In modern Vietnam, the Viet (or the Kinh, the ethnic Vietnamese) and the Muong are considered to be two different peoples, the Viet (Kinh) being the majority and the Muong a minority. In the not so distant past, however, when Vietnam’s population did not see itself in ethnic categories, the only difference between the Viet and Muong ancestors lay in their places of residence – the inhabitants of the capital city and the surrounding plains were named ‘Kinh’ while those who lived in mountain villages were called ‘Muong’. Otherwise, they were the same people, spoke nearly the same language and shared nearly the same traditions. Their commonality is emphasized in the term they are referred to by, i.e. the Viet-Muong. This chapter explores the Vietnamese and Muong languages, dialects, legends, epics and folk songs in a comparative perspective to reveal their similarities, discrepancies, influences and politics. The panelists’ goal is to identify phenomena which are specific for the Viet-Muong community as a whole and those that divide them into two separate groups - the Viet and the Muong.
One of the key advances in genome assembly that has led to a significant improvement in contig lengths has been improved algorithms for utilization of paired reads (mate-pairs). While in most assemblers, mate-pair information is used in a post-processing step, the recently proposed Paired de Bruijn Graph (PDBG) approach incorporates the mate-pair information directly in the assembly graph structure. However, the PDBG approach faces difficulties when the variation in the insert sizes is high. To address this problem, we first transform mate-pairs into edge-pair histograms that allow one to better estimate the distance between edges in the assembly graph that represent regions linked by multiple mate-pairs. Further, we combine the ideas of mate-pair transformation and PDBGs to construct new data structures for genome assembly: pathsets and pathset graphs.

Many environmental stimuli present a quasi-rhythmic structure at different timescales that the brain needs to decompose and integrate. Cortical oscillations have been proposed as instruments of sensory de-multiplexing, i.e., the parallel processing of different frequency streams in sensory signals. Yet their causal role in such a process has never been demonstrated. Here, we used a neural microcircuit model to address whether coupled theta–gamma oscillations, as observed in human auditory cortex, could underpin the multiscale sensory analysis of speech. We show that, in continuous speech, theta oscillations can flexibly track the syllabic rhythm and temporally organize the phoneme-level response of gamma neurons into a code that enables syllable identification. The tracking of slow speech fluctuations by theta oscillations, and its coupling to gamma-spiking activity both appeared as critical features for accurate speech encoding. These results demonstrate that cortical oscillations can be a key instrument of speech de-multiplexing, parsing, and encoding.
Neuronal nicotinic acetylcholine receptors (NNRs) of the α7 subtype have been shown to contribute to the release of dopamine in the nucleus accumbens. The site of action and the underlying mechanism, however, are unclear. Here we applied a circuit modeling approach, supported by electrochemical in vivo recordings, to clarify this issue. Modeling revealed two potential mechanisms for the drop in accumbal dopamine efflux evoked by the selective α7 partial agonist TC-7020. TC-7020 could desensitize α7 NNRs located predominantly on dopamine neurons or glutamatergic afferents to them or, alternatively, activate α7 NNRs located on the glutamatergic afferents to GABAergic interneurons in the ventral tegmental area. Only the model based on desensitization, however, was able to explain the neutralizing effect of coapplied PNU-120596, a positive allosteric modulator. According to our results, the most likely sites of action are the preterminal α7 NNRs controlling glutamate release from cortical afferents to the nucleus accumbens. These findings offer a rationale for the further investigation of α7 NNR agonists as therapy for diseases associated with enhanced mesolimbic dopaminergic tone, such as schizophrenia and addiction
