description: Россия входит в глобальные цифровые сети, различные цепочки передачи данных и инфраструктуры, что позволяет контактировать с глобализованным миром, проводить множество операций за несколько секунд. Однако данные не могут быть в полной безопасности, а из-за глобализации сети становится сложнее нейтрализовать внешние угрозы при помощи внутренних ресурсов. Эта проблема вызывает необходимость достижения единых стандартов в области криминалистики относительно стандартов сбора и передачи, хранения, аутентификации данных, которые могут служить в качестве доказательств по уголовному делу или иному юридическому событию. Для российского сегмента интернета в качестве ключевого риска выступает политизация технической экосистемы, например, давление со стороны правительства на коммерческие организации, предоставляющие доступ к международной сети и обслуживающие эту инфраструктуру. Еще один риск – это отсутствие доверия между разными сегментами интернета и его глобальная фрагментация по национальному и региональному признаку. Сегменты развиваются неоднородно, и это приводит к тому, что некоторые из них отстают в развитии. В целом, наибольшую сложность в криминализации преступлений в киберпространстве вызывает спектр возможностей уголовной юстиции, поскольку данная система обладает низким уровнем подготовленности к противодействию подобной деятельности. Это обусловлено целым комплексом моментов, включая высокую степень анонимности интернет-пользователей, межнациональный характер противоправной деятельности и повышенную сложность в сборе доказательной базы. Из этого следует, что требуется разработка системы социально-психологических и экономических инструментов, направленных на эффективную борьбу с киберпреступностью. С учетом того, что компьютерные данные, телекоммуникационные сети и интернет выступают в качестве объекта уголовно-правовой защиты, можно сделать вывод, что криминализация данных действий является важным шагом по успешному противостоянию преступности в этой сфере.

description: We consider the problem of constructing Wannier functions for Z_2 topological insulators in two dimensions. It is well known that there is a topological obstruction to the construction of Wannier functions for Chern insulators, but it has been unclear whether this is also true for the Z_2 case. We consider the Kane-Mele tight-binding model, which exhibits both normal (Z_2-even) and topological (Z_2-odd) phases as a function of the model parameters. In the Z_2-even phase, the usual projection-based scheme can be used to build the Wannier representation. In the Z_2-odd phase, we do find a topological obstruction, but only if one insists on choosing a gauge that respects the time-reversal symmetry, corresponding to Wannier functions that come in time-reversal pairs. If instead we are willing to violate this gauge condition, a Wannier representation becomes possible. We present an explicit construction of Wannier functions for the Z_2-odd phase of the Kane-Mele model via a modified projection scheme followed by maximal localization, and confirm that these Wannier functions correctly represent the electric polarization and other electronic properties of the insulator.
Lepton Flavour Violation and theta(13) in Minimal Resonant Leptogenesis

description: We study the impact of minimal non-supersymmetric models of resonant leptogenesis on charged lepton flavour violation and the neutrino mixing angle theta(13). Possible low-scale flavour realisations of resonant tau-, mu- and e-leptogenesis provide very distinct and predictive frameworks to explain the observed baryon asymmetry in the Universe by sphaleron conversion of an individual tau-, mu- and e-lepton-number asymmetry which gets resonantly enhanced via out-of-equilibrium decays of nearly degenerate heavy Majorana neutrinos. Based on approximate flavour symmetries, we construct viable scenarios of resonant tau-, mu- and e-leptogenesis compatible with universal right-handed neutrino masses at the GUT scale, where the required heavy-neutrino mass splittings are generated radiatively. The heavy Majorana neutrinos in such scenarios can be as light as 100 GeV and their couplings to two of the charged leptons may be large. In particular, we explicitly demonstrate the compelling role that the three heavy Majorana neutrinos play, in order to obtain successful leptogenesis and experimentally testable rates for lepton flavour violating processes, such as mu --> e gamma and mu --> e conversion in nuclei.

description: В силу стремительной глобализации общества и все более стремительного развития форм преступности, оперативные службы и все мировое сообщество сталкивается с глобальной угрозой создания экстремистских сообществ. В сети интернет облегчается процесс вербовки людей, привлечения их к участию в экстремистских группировках, при этом скрывая самого организатора. Решение глобальной проблемы экстремизма находится в интересах всего мирового сообщества, на местном же уровне, организовать противодействие данному явлению в частности и компьютерным преступлениям в целом возможно при условии наличия в штате сотрудников высококвалифицированных специалистов в сфере IT, которые бы работали посредством специализированных защищенных каналов связи, оказывая поддержку в профилактике, предотвращении, расследовании и раскрытии киберпреступлений, а также в сборе доказательств причастности лиц к совершению конкретного компьютерного преступления. Совершенствование информационных технологий открывает для человечества не только новые возможности развития, но и способствует появлению новых глобальных угроз. Информационное пространство, в котором сейчас хранятся все данные мирового сообщества, становится очень уязвимым, а, следовательно, привлекает внимание преступного сообщества. Повышенную общественную опасность представляют преступления, совершенные преступными сообществами. Экстремизм в современный период можно считать неотъемлемым признаком социальных процессов в обществе. В эпоху глобализации формируется общемировое информационное пространство, в котором экстремизм становится главной проблемой, требующей уголовно-правового и уголовно-процессуального воздействия. Экстремистское сообщество (ст. 282.1 УК РФ) ставит целью совершение преступлений экстремисткой направленности, то есть преступлений, совершённым по мотивам политической, идеологической, расовой, национальной или религиозной ненависти или вражды либо по мотивам ненависти или вражды в отношении какой-либо социальной группы, предусмотренные соответствующими статьями УК РФ.
Density-Temperature-Softness Scaling of the Dynamics of Glass-forming Soft-sphere Liquids

description: The principle of dynamic equivalence between soft-sphere and hard-sphere fluids [Phys. Rev. E \textbf{68}, 011405 (2003)] is employed to describe the interplay of the effects of varying the density n, the temperature T, and the softness (characterized by a softness parameter ν^{-1}) on the dynamics of glass-forming soft-sphere liquids in terms of simple scaling rules. The main prediction is that the dynamic parameters of these systems, such as the α-relaxation time and the long-time self-diffusion coefficient, depend on n, T, and ν only through the reduced density n^\ast \equiv nσ^{3}_{HS}(T, ν),where the effective hard-sphere diameter σ_{HS}(T, ν) is determined, for example, by the Andersen-Weeks-Chandler condition for soft-sphere-hard-sphere structural equivalence. A number of scaling properties observed in recent simulations involving glass-forming fluids with repulsive short range interactions are found to be a direct manifestation of this general dynamic equivalence principle. The self-consistent generalized Langevin equation (SCGLE) theory of colloid dynamics is shown to accurately capture these scaling rules

description: We report on a systematic study of a number of structurally identical but chemically distinct transition metal oxides in order to determine how the material-specific properties such as the composition and the strain affect the properties at the interface of heterostructures. Our study considers a series of structures containing two layers of ferromagnetic SrRuO3, with antiferromagnetic insulating manganites sandwiched in between. The results demonstrate how to control the strength and relative orientation of interfacial ferromagnetism in correlated electron materials by means of valence state variation and substrate-induced strain, respectively.
Phase transitions in a two parameter model of opinion dynamics with random kinetic exchanges

description: Recently, a model of opinion formation with kinetic exchanges has been proposed in which a spontaneous symmetry breaking transition was reported [M. Lallouache et al, Phys. Rev. E, {\bf 82} 056112 (2010)]. We generalise the model to incorporate two parameters, $λ$, to represent conviction and $μ$, to represent the influencing ability of individuals. A phase boundary given by $λ=1-μ/2$ is obtained separating the symmetric and symmetry broken phases: the effect of the influencing term enhances the possibility of reaching a consensus in the society. The time scale diverges near the phase boundary in a power law manner. The order parameter and the condensate also show power law growth close to the phase boundary albeit with different exponents. Theexponents in general change along the phase boundary indicating a non-universality. The relaxation times, however, become constant with increasing system size near the phase boundary indicating the absence of any diverging length scale. Consistently, the fluctuations remain finite but show strong dependence on the trajectory along which it is estimated.

description: The search for supersymmetric particles constitutes one of the main points of the physical program at the LHC. For the interpretation of the measured data precise theory predictions are mandatory. In the context of this thesis two complementary methods for the improvement of the predictions for the production of light-flavour squarks and the subsequent decays into a quark and the lightest neutralino are combined: higher-order corrections at fixed-order perturbation theory and parton showers.

We evolve initial data for the vacuum radial Teukolsky equation using a near horizon approximation, and find a frequency mode analogous to that found in a recent study of radiation generated by a plunging particle close to the Kerr horizon. We discuss our results in the context of that study. We also explore the utility of this mode by fitting a numerical waveform with a combination of the usual quasi-normal modes (QNMs) and the new oscillation frequency.

description: Based on the archival data from the Chandra observations of nearby galaxies, we study different sub populations of low-mass X-ray binaries (LMXBs) - dynamically formed systems in globular clusters (GCs) and in the nucleus of M31 and (presumably primordial) X-ray binaries in the fields of galaxies. Our aim is to produce accurate luminosity distributions of X-ray binaries in different environments, suitable for quantitative comparison with each other and with the output of population synthesis calculations. Our sample includes seven nearby galaxies (M31, Maffei 1, Centaurus A,M81, NGC 3379, NGC 4697, and NGC 4278) and the Milky Way, which together provide relatively uniform coverage down to the luminosity limit of E35 erg/s. In total we have detected 185 LMXBs associated with GCs, 35 X-ray sources in the nucleus of M31, and 998 field sources of which ~ 365 are expected to be background AGN. We combine these data, taking special care to accurately account for X-ray and optical incompleteness corrections and the removal of the contamination from the cosmic X-ray background sources, to produce luminosity distributions of X-ray binaries in different environments to far greater accuracy than has been obtained previously. We found that luminosity distributions of GC and field LMXBs differ throughout the entire luminosity range, the fraction of faint (log(Lx) < 37) sources among the former being ~ 4 times less than in the field population. The X-ray luminosity function (XLF) of sources in the nucleus of M31 is similar to that of GC sources at the faint end but differs at the bright end, with the M31 nucleus hosting significantly fewer bright sources. We discuss the possible origin and potential implications of these results.

description: If the fundamental mass scale of superstring theory is as low as few TeVs, the massive modes of vibrating strings, Regge excitations, will be copiously produced at the Large Hadron Collider (LHC). We discuss the complementary signals of low mass superstrings at the proposed electron-positron facility (CLIC), in e^+e^- and γγcollisions. We examine all relevant four-particle amplitudes evaluated at the center of mass energies near the mass of lightest Regge excitations and extract the corresponding pole terms. The Regge poles of all four-point amplitudes, in particular the spin content of the resonances, are completely model independent, universal properties of the entire landscape of string compactifications. We show that γγ\to e^+ e^- scattering proceeds only through a spin-2 Regge state. We estimate that for this particular channel, string scales as high as 4 TeV can be discovered at the 11σlevel with the first fb^{-1} of data collected at a center-of-mass energy \approx 5 TeV. We also show that for e^+e^- annihilation into fermion-antifermion pairs, string theory predicts the precise value, equal 1/3, of the relative weight of spin 2 and spin 1 contributions. This yields a dimuon angular distribution with a pronounced forward-backward asymmetry, which will help distinguishing between low mass strings and other beyond the standard model scenarios.

description: Refinement types sharpen systems of simple and dependent types by offering expressive means to more precisely classify well-typed terms. We present a system of refinement types for LF in the style of recent formulations where only canonical forms are well-typed. Both the usual LF rules and the rules for type refinements are bidirectional, leading to a straightforward proof of decidability of typechecking even in the presence of intersection types. Because we insist on canonical forms, structural rules for subtyping can now be derived rather than being assumed as primitive. We illustrate the expressive power of our system with examples and validate its design by demonstrating a precise correspondence with traditional presentations of subtyping. Proof irrelevance provides a mechanism for selectively hiding the identities of terms in type theories. We show that LF refinement types can be interpreted as predicates using proof irrelevance, establishing a uniform relationship between two previously studied concepts in type theory. The interpretation and its correctness proof are surprisingly complex, lending support to the claim that refinement types are a fundamental construct rather than just a convenient surface syntax for certain uses of proof irrelevance.

We analyze the detailed nature of the corresponding phases and the associated quantum and thermal phase transitions.

description: We calculate finite quantum corrections to the tribimaximal neutrino mixing pattern V_TB in three generic classes of neutrino mass models. We show that three flavor mixing angles can all depart from their tree-level results described by V_TB, among which θ_12 is most sensitive to such quantum effects, and the Dirac CP-violating phase can radiatively arise from two Majorana CP-violating phases. This theoretical scheme offers a new way to understand why θ_13 is naturally small and how three CP-violating phases are presumably correlated.

description: The vertex-cover problem on the Hanoi networks HN3 and HN5 is analyzed with an exact renormalization group and parallel-tempering Monte Carlo simulations. The grand canonical partition function of the equivalent hard-core repulsive lattice-gas problem is recast first as an Ising-like canonical partition function, which allows for a closed set of renormalization group equations. The flow of these equations is analyzed for the limit of infinite chemical potential, at which the vertex-cover problem is attained. The relevant fixed point and its neighborhood are analyzed, and non-trivial results are obtained both, for the coverage as well as for the ground state entropy density, which indicates the complex structure of the solution space. Using special hierarchy-dependent operators in the renormalization group and Monte-Carlo simulations, structural details of optimal configurations are revealed. These studies indicate that the optimal coverages (or packings) are not related by a simple symmetry. Using a clustering analysis of the solutions obtained in the Monte Carlo simulations, a complex solution space structure is revealed for each system size. Nevertheless, in the thermodynamic limit, the solution landscape is dominated by one huge set of very similar solutions.

description: In this Letter we report the LDA+DMFT (method combining Local Density Approximation with Dynamical Mean-Field Theory) results for magnetic properties of parent superconductor LaFeAsO in paramagnetic phase. Calculated uniform magnetic susceptibility shows linear dependence at intermediate temperatures in agreement with experimental data. For high temperatures ($>$1000 K) calculations show saturation and then susceptibility decreases with temperature. Contributions to temperature dependence of the uniform susceptibility are strongly orbitally dependent. It is related to the form of the orbitally-resolved spectral functions near the Fermi energy with strong temperature dependent narrow peaks for some of the orbitals. Our results demonstrate that linear-temperature dependence of static magnetic susceptibility in pnictide superconductors can be reproduced without invoking antiferromagnetic fluctuations.

description: Using the top-down approach, we study intersecting Dp-Dq brane configuration in string theory and find examples, where there can be a quantum phase transition at zero temperature induced by the violation of the Breitenlohner-Freedman (BF) bound at IR, which is done essentially by a combination of charge density and magnetic fields. In particular, there exists a Berezinskii-Kosterlitz-Thouless (BKT) type of transition for D3-D5 and D5-D5 systems. The study of the BKT type of transition is initiated by Jensen et al. [Phys. Rev. Lett. {\bf 105}, 041601 (2010) ] for a D3-D5 system with nonzero charge density and a magnetic field. Here, we show that one can have the BKT transition for a D3-D5 system even in the absence of charge density but requires multiple magnetic fields. In this case the field theory lives in 2+1 dimensions, whereas for the D5-D5 type, the transition requires the presence of both the charge density and magnetic fields and the dual field theory lives on a 3+1 dimensional spacetime. We also study the D3-D7 system but it does not show the BKT type of transition.

description: We investigated the homogeneous coexistence of spin-density-wave (SDW) and superconducting (SC) states via 75As-nuclear magnetic resonance (NMR) in CaFe(1-x)Co(x)AsF and found that the electronic and magnetic properties of this compound are intermediate between those of LaFeAsO(1-x)F(x) and Ba(Fe(1-x)Co(x))2As2. For 6% Co-doped samples, the paramagnetic spectral weight completely disappears in the crossover regime between the SDW and SC phases followed by the anomalous behavior of relaxation rate (1/T1), implying that the two phases are not segregated. The 59Co-NMR spectra show that spin moments are not commensurate but spatially modulated. These experimental results suggest that incommensurate SDW (IC-SDW) and SC states are compatible in this compound.

description: The large-angle, low multipole cosmic microwave background (CMB) provides a unique view of the largest angular scales in the Universe. Study of these scales is hampered by the facts that we have only one Universe to observe, only a few independent samples of the underlying statistical distribution of these modes, and an incomplete sky to observe due to the interposing Galaxy. Techniques for reconstructing a full sky from partial sky data are well known and have been applied to the large angular scales. In this work we critically study the reconstruction process and show that, in practise, the reconstruction is biased due to leakage of information from the region obscured by foregrounds to the region used for the reconstruction. We conclude that, despite being suboptimal in a technical sense, using the unobscured region without reconstructing is the most robust measure of the true CMB sky. We also show that for noise free data reconstructing using the usual optimal, unbiased estimator may be employed without smoothing thus avoiding the leakage problem. Unfortunately, directly applying this to real data with noise and residual, unmasked foregrounds yields highly biased reconstructions requiring further care to apply this method successfully to real-world CMB.

description: In this paper we review some connections recently discovered between topological insulators and certain classes of quantum spin liquids, focusing on two and three spatial dimensions. In two dimensions we show the integer quantum Hall effect plays a key role in relating topological insulators and chiral spin liquids described by fermionic excitations, and we describe a procedure for "generating" a certain class of topological states. In three dimensions we discuss interesting relationships between certain quantum spin liquids and interacting "exotic" variants of topological insulators. We focus attention on better understanding interactions in topological insulators, and the phases nearby in parameter space that might result from moderate to strong interactions in the presence of strong spin-orbit coupling. We stress that oxides with heavy transition metal ions, which often host a competition between electron interactions and spin-orbit coupling, are an excellent place to search for unusual topological phenomena and other unconventional phases.

Extended Green-Liouville asymptotics and vacuum polarization for lukewarm black holes

Year: 2010

description: We consider a quantum field on a lukewarm black hole spacetime. We introduce a new uniform approximation to the radial equation, constructed using an extension of Green-Liouville asymptotics. We then use this new approximation to construct the renormalized vacuum polarization in the Hartle-Hawking vacuum. Previous calculations of the vacuum polarization rely on the WKB approximation to the solutions of the radial equation, however the nonuniformity of the WKB approximations obscures the results of these calculations near both horizons. The use of our new approximation eliminates these obscurities, enabling us to obtain explicitly finite and easily calculable values of the vacuum polarization on the two horizons.

Warped General Gauge Mediation

description: We develop the formalism of "General gauge mediation" for five dimensional theories in a slice of AdS space. A set of current correlators encodes the effect of a supersymmetry breaking hidden sector localised on the IR brane. These current correlators provide a tree-level gaugino mass and loop-level sfermion masses on the UV brane. We also use this formalism to calculate the Casimir energy and masses for bulk hyperscalars. To illustrate this general construction we consider a perturbative hidden sector of generalised messengers coupled to a spurion. For models with large warping, we find that when the AdS warp factor $k$ is less than the characteristc mass scale $M$ of the hidden sector, the whole Kaluza-Klein tower of vector superfields propagate supersymmetry breaking effects to the UV brane. When $M$ is less than $k$, the zero modes dominate.

Year: 2014

description: A new test method is presented that allows for a more accurate determination of the slip modulus of crossing areas between orthogonally bonded boards compared to the methods used so far. The slip moduli obtained by the new method are compared to the values evaluated from bending tests with CLT beams and from tests with crossing areas subjected to unidirectional shear stresses and the agreement is found to be good.

description: Over the last years, Ambient Intelligence (AmI) has been pointed out as an alternative to current practices in home care. AmI supports the concept of Ambient Assisted Living, which aims to allow older people to remain independent at their own homes for longer. The integration of a mobile robot into a database-centric platform for Ambient Assisted Living is described in this thesis. The robot serves as a rst-aid agent to respond to emergencies, such as a fall, detected by the intelligent environment. To accomplish that the robot must 1) be able to receive tasks from intelligent environment; 2) execute the task; 3) report the progress and the result of the task back to the intelligent environment.
The system of the robot is built on top of the Robot Operating System, while the existing intelligent environment on a PostgreSQL database. To receive tasks from the intelligent
environment, the robot maintains an active connection with the database and subscribes to specic tasks. A task, for example, is to nd a person in the environment, which includes asking if the person is doing well. To nd a person a map-based approach and a face recognition are used. The robot can interact with people in the environment using text-to-speech and speech recognition. The active connection with the database enables the robot to report back about the execution of a task and to receive new or abort tasks. As a conclusion, together with an AAL system, mobile robots can support people living alone. The system has been implemented and successfully tested at Halmstad University on a Turtlebot 2. The code is available on Github.
