326 species of spiders belonging to 26 families are recorded from the Bolshekhekhtsyrski State Nature Reserve,of them 70 are new records for the reserve and six are new to the fauna of Russia:Asperthorax borealis Ono et Saito,2001; Cyclosa kumadai Tanikawa,1992; Cyclosa okumae Tanikawa,1992(earlier it was identified as C. argenteoalba Bosenberg et Strand,1906); Haplodrassus taepaikensis Paik,1992; Hypselistes fossilobus Fei et Zhu,1993; and Pachygnatha gaoi Zhu et al.,2003. The name Pronous minutus (S. Saito,1939) is synonymized with Pronoides brunneus Schenkel,1936. The male of H. taepaikensis is illustrated for the first time. Composition of the fauna is briefly discussed; 41% of the recorded species have their ranges confined to the SE Palaearctics. By its species diversity,the reserve's fauna is the second largest local fauna eastward of the Urals. An expected spider diversity of this reserve is likely to be over 400 species.

High-purity straight and discrete multiwalled boron nitride nanotubes （BNNTs） were grown via a boron oxide vapor reaction with ammonia using LiNO3 as a promoter. Only a trace amount of boron oxide was detected as an impurity in the BNNTs by energy-dispersive X-ray （EDX） and Raman spectroscopies. Boron oxide vapor was generated from a mixture of B, FeO, and MgO powders heated to 1,150 ℃, and it was transported to the reaction zone by flowing ammonia. Lithium nitrate was applied to the upper side of a BN bar from a water solution. The bar was placed along a temperature gradient zone in a horizontal tubular furnace. BNNTs with average diameters of 30-50 nm were mostly observed in a temperature range of 1,280-1,320 ℃. At higher temperatures, curled polycrystalline BN fibers appeared. Above 1,320 ℃, the number of BNNTs drastically decreased, whereas the quantity and diameter of the fibers increased. The mechanism of BNNT and fiber growth is proposed and discussed.

We build a model of storage of well-defined positional information in probabilistic sequence patterns. Once a pattern is defined, it is possible to judge the effect of any mutation in it. We show that the frequency of beneficial mutations can be high in general and the same mutation can be either advantageous or deleterious depending on the pattern’s context. The model allows to treat positional information as a physical quantity, formulate its conservation law and to model its continuous evolution in a whole genome, with meaningful applications of basic physical principles such as optimal efficiency and channel capacity. A plausible example of optimal solution analytically describes phase transitions-like behavior. The model shows that, in principle, it is possible to store error-free information on sequences with arbitrary low conservation. The described theoretical framework allows one to approach from novel general perspectives such long-standing paradoxes as excessive junk DNA in large genomes or the corresponding G- and C-values paradoxes. We also expect it to have an effect on a number of fundamental concepts in population genetics including the neutral theory, cost-of-selection dilemma, error catastrophe and others.
