О таможенной политике России в северном Азербайджане (XIX- начало XX ВВ.)
Following the Russian conquest of the territories of Azerbaijani khanates in the first decades of the 19th century, a stong need to create custom posts on the southern borders of the Russian Empire arose. The Chief of the Russian troops in the Caucasus P.D. Tsitsianov initiated the establishment of customs posts in the South Caucasus in 1803. The article states that shortly after the conquest of the territory of the Baku Khanate (October 1806), the official document, which provided for the creation of new customs offices, was submitted for approval by the Russian Emperor Alexander I (1801-1825). Therefore, an implementation of the Russian customs policy in the mentioned territory begins with this historic moment
From Virtual to Physical: Integration of Chemical Logic Gates
Cataloged from PDF version of article.Integration by parts: Advanced information processing at the molecular level requires integrated logic gates, which has to date been possible only virtually. Now, two independently working AND molecular logic gates are brought together by "click" chemistry to form integrated logic gates which respond exactly as predicted from such an integration scheme (see picture, EET=excitation energy transfer).

Cyanide sensing via metal ion removal from a fluorogenic BODIPY complex
Cataloged from PDF version of article.We report a highly selective and sensitive reversible cyanide sensor operating in the ‘turn-off-on’ mode via decomplexation of Cu(II) ions from a brightly fluorescent boradiazaindacene derivative. The sensor is reversible as the emission signal originates from the dynamic equilibration of dipicolylamine–Cu(II) and tetracyanocuprate complex ions
Expanded Bodipy Dyes: Anion Sensing Using a Bodipy Analog with an Additional Difluoroboron Bridge
Cataloged from PDF version of article.Oxalyl-tethered pyrroles can be doubly bridged with two difluoroboron chelating units to yield bright orange dyes. Interestingly, in polar organic solvents, the addition of fluoride and cyanide result in reversible detachment of the otherwise stable difluoroboron bridges, resulting in sharp changes in color. Thus, this novel compound behaves as a highly selective chromogenic sensor for fluoride and cyanide ions
Modular logic gates: cascading independent logic gates via metal ion signals
Cataloged from PDF version of article.Abstract
Systematic cascading of molecular logic gates is an important issue to be addressed for advancing research in this field. We have demonstrated that photochemically triggered metal ion signals can be utilized towards that goal. Thus, independent logic gates were shown to work together while keeping their identity in more complex logic designs. Communication through the intermediacy of ion signals is clearly inspired from biological processes modulated by such signals, and implemented here with ion responsive molecules. © 2014 The Royal Society of Chemistry.
Collective Excitations of (154)Sm nucleus at FEL{gamma}+LHC Collider
The production of collective excitations of the (154)Sm at FEL{gamma}+LHC
collider is investigated. We show that this machine will be a powerful tool for
investigation of high energy level excitations.Comment: 6 pages, 1 figure, 4 table
Near-IR-Triggered, Remote-Controlled Release of Metal Ions: A Novel Strategy for Caged Ions
Cataloged from PDF version of article.A ligand incorporating a dithioethenyl moiety is cleaved into fragments which have a lower metal-ion affinity upon irradiation with low-energy red/near-IR light. The cleavage is a result of singlet oxygen generation which occurs on excitation of the photosensitizer modules. The method has many tunable factors that could make it a satisfactory caging strategy for metal ions

CLIC-LHC Based FEL-Nucleus Collider: Feasibility and Physics Search Potential
The feasibility of a CLIC-LHC based FEL-nucleus collider is investigated. It
is shown that the proposed scheme satisfies all requirements of an ideal photon
source for the Nuclear Resonance Fluorescence method. The tunability,
monochromaticity and high polarization of the FEL beam together with high
statistics and huge energy of LHC nucleus beams will give an unique opportunity
to determine different characteristics of excited nuclear levels. The physics
potential of the proposed collider is illustrated for a beam of Pb nuclei.Comment: 19 pages, 3 figure
Parabolic oblique derivative problem in generalized Morrey spaces
We study the regularity of the solutions of the oblique derivative problem
for linear uniformly parabolic equations with VMO coefficients. We show that if
the right-hand side of the parabolic equation belongs to certain generalized
Morrey space than the strong solution belongs to the corresponding generalized
Sobolev-Morrey space
