Approaches to the modeling of the Geospace of economic and ecologic activities, including a set of concepts, principles and models, are revealed. Basic and secondary categories of geospatial modelling are formulated. General and detaled principles of the modelling of territorial environmental situation are shown in order to monitor the environmental, economic and business activities. Geoecological territorial concepts and categories are illustrated. Various geospatical formalizms, required for different stages of monitoring and control of geoecological situation (environment assessment, modeling of geoecological situation, elaboration of recommendations for its normalization) are described. Models and methods to support the techniques of automatic analysis and control of territorial environmental situation are discussed
Within the monsoon period (May-September) there is enough water (1800-2250 mm). Distribution of water for irrigation is realized in accordance with the customary law norms. An irrigation channel can be the property of one family, the property of several families with the land plots located closely or discretely. The village community members take part in the works for construction, support and reconstruction of the irrigation system. When water comes to the plots, women can catch small fish there to be quickly cooked or dried and stored.
The main efforts of modern geoecology focus on various aspects of monitoring the state of the natural environment within the sphere of anthropogenic impacts on raw materials complexes and on determining the irreversible level of adverse impacts and consequences of natural disasters in the absence of effective tools and systems for early forecasting and detection of hazards and environmental risks (erosion, oil spills, oil and gas leaks and contamination of surface and groundwater, landslides, collapses, subsidence, mining, fire, among others). As a result, even with the highest methodological and technical level of modern research, there remains trivial conclusion on the need to protect nature. This leaves open the main question of effective methods of nature protection and the necessary changes in technologies and methods of data management. The improvement of the methodological basis for the design of mining systems to achieve integrated development of subsoil is aimed at advancing the innovative energy and resource-saving geotechnologies, which ensure the required efficiency and safety of work, including early detection of potential hazards and risks. In this study, an integrated approach to the processing of remotely sensed data is being developed, which is envisaged to share the results of the measurements obtained in Russia and Kenya by various satellite-based technologies in both optical and radar bands.
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
