The paper describes the GUSMP (North Sea Route Directorate) expert council session on design of a powerful icebreaker 18000–24000 HP held June 15, 1935 in Leningrad, based archive documents. Analysis materials sheds light state-of-the-art building mid-1930s. standpoint academician A.N. Krylov as well administration is particularly interesting.

We present the first theoretical prediction of production rate $1^{-+}$ light hybrid meson $\eta_1$ in $J/\psi$ radiative decays. In $N_f=2$ lattice QCD formalism with pion mass $m_\pi\approx 350$ MeV, related electromagnetic multipole form factors are extracted from three-point functions that involve necessarily quark annihilation diagrams, which calculated through distillation method. The par...

We present a formal model built for verification of the hardware Tera-Scale ARchitecture (TSAR), focusing on its Distributed Hybrid Cache Coherence Protocol (DHCCP). This protocol is by nature asynchronous, concurrent and distributed, which makes classical validation of the design (e.g. through testing) difficult. We therefore applied formal methods to prove essential properties of the protocol...

The genus Macronemus Dejean, 1835 is redescribed and two new species are described: Macronemus mimus sp. nov. from Brazil (Bahia to Santa Catarina) and Argentina and Macronemus giuglarisi sp. nov. from French Guiana and Brazil (Amapá, Amazonas). M. verrucosus (Pascoe, 1866) is considered a new synonym of M. asperulus White, 1855. New distributional data and a key to the seven species of the gen...

Two species, Ptecticus brevispinus sp. nov. and P. guangxiensis sp. nov., from China are described and illustrated. Additional two species, P. longispinus Rozkošný & Kovac, 2003 and P. melanurus (Walker, 1848), are recorded from China for the first time. A checklist of the known Chinese Ptecticus Loew, 1855 species together with their geographical distribution and a new identification key (19 s...

The poorly-known genus Conosimus Mulsant et Rey, 1855 (Hemiptera: Fulgoroidea: Issidae) includes six species and is briefly reviewed. Adults and fifth instars of a new species, Conosimus baenai n sp., are described and compared with other species in the genus. The new species is associated with an endemic shrub, Echinospartum boissieri, in Jaen, Spain, in the south of the Iberian Peninsula, one...
