An Overview of Remote Sensing in Russian Forestry

The Russian Federation possesses vast forested areas, containing about 23% of the world's closed forests. A significant part of these forestlands is neither managed nor regularly monitored. This is due in part to the absence of developed infrastructure in the remote northern regions, which hampers the collection of data on forest inventory and monitoring in all areas by precise and expensive on-ground methods. As a result, the monitoring in all areas by precise and expensive on-ground methods. As a result, the former Soviet Union conducted intensive research on remote sensing during the last few decades, resulting in significant achievements. However, there has been a noticeable decline in remote sensing research and applications in the Russian forest sector from 1990-1998. Russia needs a new system of forest inventory and monitoring capable of providing reliable, practical information for sustainable forest management. Such a system should take into account current national demands on the Russian forest sector as well as the international obligations of the country. Remote sensing methods are an indispensable part of such a system. These methods will play a crucial role in critical applications such as ensuring the sustainability of forest management, protecting threatened forests, fulfilling the countrys Kyoto Protocol obligations, and others. This paper presents an overview of past and current remote sensing methods in the Russian forest sector, including both practical and scientific applications. Based on this overview, relevant applications of remote sensing methods in the Russian forest sector are discussed. This discussion considers current Russian economic conditions and the direction of political and social development of the country

Spectrum of π\pi-electrons in Graphene As a Macromolecule

We report the exact solution of spectral problem for a graphene sheet framed by two armchair- and two zigzag-shaped boundaries. The solution is found for the $\pi$ electron Hamiltonian and gives, in particular, a closed analytic expression of edge-state energies in graphene. It is shown that the lower symmetry of graphene, in comparison with $C_{6h}$ of 2D graphite, has a profound effect on the graphene band structure. This and other obtained results have far going implications for the understanding of graphene electronics. Some of them are briefly discussed.Comment: Revised in connection with publication in PRL, editin

Comparing Etymological Characteristics of Plant Naming in Yakut, Even, and Evenk Languages

This article considers issues of language contacts between Yakut, Even, and Evenk people through an analysis of plant vocabulary. We define etymological characteristics of fixed lexical units that denote plant names and present results of a comparative analysis of plant naming in these three languages, with emphasis on lexical parallels and structural types in designating plant names. To our knowledge, this is the first research to undertake a comparative study of plant naming in the Yakut and Tungusic languages (Even and Evenk) with consideration of the methods of their formation. The study is highly relevant because of the unique contribution of plant-world vocabulary in helping to clarify peculiarities of native speakers’ natural environments. Our results show that, based on lexical units with stable semantic meaning, the Evenk language is in the closest position vis-à-vis Yakut. There are 16 names in Yakut of plants and four of common names of herbs that grow on the territory of the Republic of Sakha (Yakutia) and have borrowed names in Evenk and Even. Twenty-eight names have lexical parallels in Evenk (including variations) and two in Even.Cet article se penche sur la question des contacts linguistiques entre les Yakoutes, les Évènes et les Evenkis au moyen de l’analyse du vocabulaire des plantes. Nous définissons les caractéristiques étymologiques d’unités lexicales fixes dénotant les noms de plantes et présentons les résultats de l’analyse comparative de la nomenclature de plantes dans ces trois langues, en mettant l’accent sur les parallèles lexicaux et les types structuraux de la désignation des noms de plantes. À notre connaissance, il s’agit de la première recherche à entreprendre l’étude comparative de la nomenclature botanique en langues yakoute et toungouse (évène et evenki) tout en tenant compte de leurs méthodes de formation. Cette étude est d’une grande pertinence, car l’apport unique du vocabulaire des plantes aide à expliquer les particularités des milieux naturels des locuteurs natifs. Selon nos résultats, fondés sur les unités lexicales dotées de significations sémantiques stables, l’evenki est la langue la plus proche du yakoute. En yakoute, il y a 16 noms de plantes et quatre noms communs d’herbes dans le territoire de la république de Sakha (Yakoutie) dont les noms ont été empruntés à l’evenki et à l’évène. Vingt-huit noms ont des parallèles lexicaux en evenki (variantes y comprises), et deux en évène

Design of Pre-Dumping Ring Spin Rotator with a Possibility of Helicity Switching for Polarized Positrons at the ILC

The use of polarized beams enhance the possibility of the precision measurements at the International Linear Collider (ILC). In order to preserve the degree of polarization during beam transport spin rotators are included in the current TDR ILC Lattice. In this report some advantages of using a combined spin rotator/spin flipper are discussed. A few possible lattice designs of spin flipper developed at DESY in 2012 are presented.Comment: Talk presented at the International Workshop on Future Linear Colliders (LCWS15), Whistler, Canada, 2-6 November 201

High folic acid consumption leads to pseudo-MTHFR deficiency, altered lipid metabolism, and liver injury in mice.

Increased consumption of folic acid is prevalent, leading to concerns about negative consequences. The effects of folic acid on the liver, the primary organ for folate metabolism, are largely unknown. Methylenetetrahydrofolate reductase (MTHFR) provides methyl donors for S-adenosylmethionine (SAM) synthesis and methylation reactions
