description: We compute the next-to-next-to-leading order (NNLO) QCD correction to the total cross-section for the reaction gg \to t\bar t + X. Together with the partonic channels we computed previously, the result derived in this letter completes the set of NNLO QCD corrections to the total top pair production cross-section at hadron colliders. Supplementing the fixed order results with soft-gluon resummation with next-to-next-to-leading logarithmic accuracy we estimate that the theoretical uncertainty of this observable due to unknown higher order corrections is about 3% at the LHC and 2.2% at the Tevatron. We observe a good agreement between the Standard Model predictions and the available experimental measurements. The very high theoretical precision of this observable allows a new level of scrutiny in parton distribution functions and new physics searches.

description: Рассматривается задача слежения за точкой максимальной мощности фотоэлектрического массива. Разработана система слежения на основе модифицированной нечеткой нейросети. В сравнении с существующими нечеткими нейросетями модифицированная нечеткая нейросеть содержит рекуррентные нейросети, одна из которых аппроксимирует многомерные функции принадлежности модифицированной нечеткой нейросети на основе экспериментальных данных. Для создания оптимальной архитектуры модифицированной нечеткой нейросети разработан модифицированный многомерный алгоритм роя частиц, инициализирующий начальное положение лучшей частицы роя и ее размерности методом Нгуена – Видроу и сочетающий этапы глобальной оптимизации многомерными частицами роя с этапами градиентного спуска алгоритмом Левенберга – Марквардта. Разработанная система слежения за точкой максимальной мощности фотоэлектрического массива на основе модифицированной нечеткой нейросети в условиях случайных возмущений апробирована в ходе экспериментального моделирования в среде Octave. Результаты экспериментального моделирования демонстрируют робастность и эффективность системы слежения за точкой максимальной мощности фотоэлектрического массива на основе модифицированной нечеткой нейросети в сравнении со стандартными моделями управления с ПИД-контроллером на основе алгоритма возмущения и наблюдения, возрастающей проводимости.
description: The article considers the task of maximum power point tracking of a photovoltaic array. A photovoltaic array maximum power point tracking system based on a modified fuzzy neural network is developed. Compared to existing fuzzy neural networks a modified fuzzy neural network includes recurrent neural networks, one of which approximates multidimensional membership functions based on experimental data. In order to create an optimal architecture of a modified fuzzy neural network, we developed a modified multi-dimensional particle swarm algorithm. The algorithm generates an initial particle position based on the Nguyen–Widrow method and combines the stages of global optimization based on a multi-dimensional particle swarm optimization with the stages of gradient descent based on the Levenberg–Marquardt algorithm. The validity and advantages of the proposed photovoltaic array maximum power point tracking system based on a modified fuzzy neural network under random perturbations by numerical simulations in Octave are demonstrated. The simulation results show that the proposed tracking system achieves competitive performance and robustness, as compared to a classical control model with a PID controller based on perturbation and observation, or incremental conductance algorithm.

description: The conformational vibrations of Z-DNA with counterions are studied in framework of phenomenological model developed. The structure of left-handed double helix with counterions neutralizing the negatively charged phosphate groups of DNA is considered as the ion-phosphate lattice. The frequencies and Raman intensities for the modes of Z-DNA with Na+ and Mg2+ ions are calculated, and the low-frequency Raman spectra are built. At the spectra range about the frequency 150 cm-1 new mode of ion-phosphate vibrations is found, which characterizes the vibrations of Mg2+ counterions. The results of our calculations show that the intensities of Z-DNA modes are sensitive to the concentration of magnesium counterions. The obtained results describe well the experimental Raman spectra of Z-DNA.

description: Semi-local quantum critical behaviour in $D-1$ spacetime dimensions can be holographically described by metrics that are conformal to $AdS_2\times\mathbb{R}^{D-2}$, with the conformal factor characterised by a parameter $η$. We analyse such "$η$-geometries" in a top-down setting by focussing on the $U(1)^4$ truncation of D=4 N=8 gauged supergravity. The model has extremal black hole solutions carrying three non-zero electric or magnetic charges which approach $AdS_4$ in the UV and an $η=1$ geometry in the IR. Adding a fourth charge provides a mechanism to resolve the singularity of the $η$-geometry, replacing it with an $AdS_2\times\mathbb{R}^2$ factor in the IR, while maintaining a large region where the $η$-geometry scaling is approximately valid. Some of the magnetically charged black hole solutions preserve supersymmetry while others just preserve it in the IR. Finally, we show that $η$-geometries, with various values of $η$, can be obtained from the dimensional reduction of geometries consisting of $AdS$ or Lifshitz geometries with flat directions.

description: It is shown that delocalized vortex solitons in relativistic pair plasmas with small temperature asymmetries can be unstable for intermediate intensities of the background electromagnetic field. Instability leads to the generation of ever-expanding cavitating bubbles in which the electromagnetic fields are zero. The existence of such electromagnetic bubbles is demonstrated by qualitative arguments based on a hydrodynamic analogy, and by numerical solutions of the appropriate Nonlinear Schrödinger equation with a saturating nonlinearity.

description: The mode of the serrated deformation is investigated mathematically in framework
of the thermoactivation model of unstable plastic deformation in metals at low temperatures.
The obtained solutions in the framework of known models, however, do not fully correspond
to experimental situation, as the stress oscillations in reality are usually irregular and
inhomogeneous. By this reason, additionally, the elastic correlations of neighboring
deformation zones were taken into account in the model. Numerical analysis model showed
that time dependence of the stress, temperature and plastic deformation rate acquires an
irregular stochastic character and is represented as an attractive set of trajectories in the phase
space of these variables – "strange attractor".
Social Resilience in Online Communities: The Autopsy of Friendster

description: We empirically analyze five online communities: Friendster, Livejournal, Facebook, Orkut, Myspace, to identify causes for the decline of social networks. We define social resilience as the ability of a community to withstand changes. We do not argue about the cause of such changes, but concentrate on their impact. Changes may cause users to leave, which may trigger further leaves of others who lost connection to their friends. This may lead to cascades of users leaving. A social network is said to be resilient if the size of such cascades can be limited. To quantify resilience, we use the k-core analysis, to identify subsets of the network in which all users have at least k friends. These connections generate benefits (b) for each user, which have to outweigh the costs (c) of being a member of the network. If this difference is not positive, users leave. After all cascades, the remaining network is the k-core of the original network determined by the cost-to-benefit c/b ratio. By analysing the cumulative distribution of k-cores we are able to calculate the number of users remaining in each community. This allows us to infer the impact of the c/b ratio on the resilience of these online communities. We find that the different online communities have different k-core distributions. Consequently, similar changes in the c/b ratio have a different impact on the amount of active users. As a case study, we focus on the evolution of Friendster. We identify time periods when new users entering the network observed an insufficient c/b ratio. This measure can be seen as a precursor of the later collapse of the community. Our analysis can be applied to estimate the impact of changes in the user interface, which may temporarily increase the c/b ratio, thus posing a threat for the community to shrink, or even to collapse.

description: The combined effect of boron addition and ausforming on the structure of low
carbon low alloyed steel after the transformation of austenite has been investigated in a wide
range of cooling rates. It is shown that boron hinders formation of polygonal ferrite in
continuous cooling regardless of austenite predeformation and suppresses appearance of
acicular ferrite. A qualitative explanation of this effect is proposed in terms of the
deformation induced boron segregation on boundaries of austenite grains and subgrains.
Practical significance of the obtained results is discussed in application to the
thermomechanical treatment of the considered steels.
INFLUENCE OF ZR SOLUTE ON THE STRUCTURAL, MECHANICAL, AND THERMAL PROPERTIES OF NANOTWINNED AL ALLOYS
Creators: name: Richter, Nicholas A
Publisher: name: Purdue University Graduate School

Subjects: Metals and alloy materials

description: Aluminum (Al) possesses a plenitude of remarkable properties, such as strong corrosion resistance, high thermal and electrical conductivity, and high specific strength. However, Al and its alloys are still remarkably weaker than most high strength steels and susceptible to drastic softening at high temperatures, preventing many applications where its low density would be beneficial. Severe plastic deformation can yield ultra-fine grained Al alloys with similar strengths as steels, although they are highly unstable even at room temperature. Nanotwinned (NT) metals have demonstrated concomitant strength and ductility, enabled by twin boundaries which simultaneously act to inhibit dislocation motion and generate partial dislocations that aid in plasticity. In spite of having a high stacking fault energy, nanotwins have been introduced into Al alloys using transition metal solutes during magnetron sputtering. This thesis aims to explore the impact Zr has on the microstructure, deformation, and thermal stability of nanotwins in NT Al. Our studies identify how Zirconium (Zr) aids in the formation of a significant volume fraction of 9R phase and an abundance of finely spaced incoherent twin boundaries, leading to a maximum hardness of 4.2GPa. They further uncover through in-situ micropillar compression that NT Al-Zr alloys are highly deformable and reach a flow stress of ~1.1GPa. Constant strain rate nanoindentation tests demonstrate the enhanced strain rate sensitivity in NT Al-Zr alloys. Zr is also identified to be a remarkable thermal stabilizer when incorporated into NT Al-Co alloys, with no apparent softening up to 450 °C (0.78 T­m). The influence of substrate texture on nanotwinned Al-Zr alloys microstructure was also thoroughly explored.

description: Single-particle states in electronic Bloch bands form a Riemannian manifold whose geometric properties are described by two gauge invariant tensors, one being symmetric the other being antisymmetric, that can be combined into the so-called Fubini-Study metric tensor of the projective Hilbert space. The latter directly controls the Hall conductivity. Here we show that the symmetric part of the Fubini-Study metric tensor also has measurable consequences by demonstrating that it enters the current noise spectrum. In particular, we show that a non-vanishing equilibrium current noise spectrum at zero temperature is unavoidable whenever Wannier states have non-zero minimum spread, the latter being quantifiable by the symmetric part of the Fubini-Study metric tensor. We illustrate our results by three examples: (1) atomic layers of hexagonal boron nitride, (2) graphene, and (3) the surface states of three-dimensional topological insulators when gaped by magnetic dopants.

Weighing Galaxy Clusters with Gas. I. On the Methods of Computing Hydrostatic Mass Bias

description: Mass estimates of galaxy clusters from X-ray and Sunyeav-Zel'dovich observations assume the intracluster gas is in hydrostatic equilibrium with their gravitational potential. However, since galaxy clusters are dynamically active objects whose dynamical states can deviate significantly from the equilibrium configuration, the departure from the hydrostatic equilibrium assumption is one of the largest sources of systematic uncertainties in cluster cosmology. In the literature there has been two methods for computing the hydrostatic mass bias based on the Euler and the modified Jeans equations, respectively, and there has been some confusion about the validity of these two methods. The word "Jeans" was a misnomer, which incorrectly implies that the gas is collisionless. To avoid further confusion, we instead refer these methods as "summation" and "averaging" methods respectively. In this work, we show that these two methods for computing the hydrostatic mass bias are equivalent by demonstrating that the equation used in the second method can be derived from taking spatial averages of the Euler equation. Specifically, we identify the correspondences of individual terms in these two methods mathematically and show that these correspondences are valid to within a few percent level using hydrodynamical simulations of galaxy cluster formation. In addition, we compute the mass bias associated with the acceleration of gas and show that its contribution is small in the virialized regions in the interior of galaxy cluster, but becomes non-negligible in the cluster outskirts of massive clusters where materials are being actively accreted. We discuss implications for understanding the origin of hydrostatic mass biases and for characterizing them using hydrodynamical simulations as well as observations.

An overview of major storage manufacturers and reliability indicators calculations of storage equipment are given. The study aims to analyze the reliability of the elements of disk subsystems based on operational data. The main features that corporate-level data storage systems should have are reliability and fault tolerance. Data accessibility is achieved through the full and partial backup of active storage components, as well as through advanced data integrity functions. As for indicators of reliability, we chose the failure rate and the mean time to failure. After processing the input data, the probabilities of failure-free operation, the probability of failures, the failure rate, and the failure frequency are calculated, and the graphs are plotted. The calculated values of the failure rate and the mean time to failure for the data storage elements are obtained.

description: We analytically investigate the phase transition between the holographic insulator and superconductor with Weyl corrections by using the variational method for the Sturm-Liouville eigenvalue problem. We find that similar to the curvature corrections, in p-wave model, the higher Weyl couplings make the insulator/superconductor phase transition harder to occur. However, in s-wave case the Weyl corrections do not influence the critical chemical potential, which is in contrast to the effect caused by the curvature corrections. Moreover, we observe that the Weyl corrections will not affect the critical phenomena and the critical exponent of the system always takes the mean-field value in both models. Our analytic results are found to be in good agreement with the numerical findings.

description: Two-dimensional nanomaterials (2D) have attracted significant attention as next generation materials. Multiple applications due to physico-chemical proprieties and the fascinating layered structure of a thickness of at least one atomic layer have emerged. However, concerns have been raised about the safety and biocompatibility of 2D nanomaterials due to contradictory results in several in vitro and in vivo nanotoxicological studies. Specifically, scientific data on the potential hazard of nanoparticles has underline the capability of layered nanomaterials to cross biological barriers, inducing reduction on cellular viability and increasing oxidative stress. In the last decade, the application of 2D nanomaterials has seen a rapid growing in the industrial field and, as a consequence, the safety assessment is necessary in order to develop biocompatible and safe nanotechnology. Notwithstanding numerous research efforts being made in the past decade to assess the different toxicity of nanomaterials, most of these scientific works focus on laboratory made nanoparticles, without tackling numerous aspects, such as apposite nanoparticle physico-chemical characterization, relevant doses and exposure duration. Therefore, the aim of this PhD thesis is to investigate the possible in vitro acute toxic effects of several 2D nanomaterials beyond graphene, considering the different physico-chemical proprieties of commercial graphene oxide, transition metal dichalcogenides (TMDs) and boron nitride, as well as the potential chemical degradation and oxidation in the environmental fate of TMDs, taking into consideration the possible differences in the toxicological responses of different eukaryotic and prokaryotic cells. The main goal of this thesis was to use different cellular models and in vitro cytotoxic assays to address several challenges in nanotoxicology, in order to increase our understanding of the biological interactions between 2D nanomaterials and biological systems.

description: Using both wavelet and Fourier analysis, a study has been undertaken of the changes in the quasi-periodic variations in solar photospheric fields in the build-up to one of the deepest solar minima experienced in the past 100 years. This unusual and deep solar minimum occurred between solar cycles 23 and 24. The study, carried out using ground based synoptic magnetograms spanning the period 1975.14 to 2009.86, covered solar cycles 21, 22 and 23. A hemispheric asymmetry in periodicities of the photospheric fields was seen only at latitudes above $\pm45{^{\circ}}$ when the data was divided, based on a wavelet analysis, into two parts: one prior to 1996 and the other after 1996. Furthermore, the hemispheric asymmetry was observed to be confined to the latitude range 45${^{\circ}}$ to 60${^{\circ}}$. This can be attributed to the variations in polar surges that primarily depend on both the emergence of surface magnetic flux and varying solar surface flows. The observed asymmetry when coupled with the fact that both solar fields above $\pm45{^{\circ}}$ and micro-turbulence levels in the inner-heliosphere have been decreasing since the early to mid nineties (Janardhan et al., 2011) suggests that around this time active changes occurred in the solar dynamo that governs the underlying basic processes in the sun. These changes in turn probably initiated the build-up to the very deep solar minimum at the end of the cycle 23. The decline in fields above $\pm45{^{\circ}}$ for well over a solar cycle, would imply that weak polar fields have been generated in the past two successive solar cycles \textit{viz.} cycles 22 and 23. A continuation of this declining trend beyond 22 years, if it occurs, will have serious implications on our current understanding of the solar dynamo.

description: Giant multipole resonances in Nd and Sm isotopes are studied by employing the quasiparticle-random-phase approximation on the basis of the Skyrme energy-density-functional method. Deformation effects on giant resonances are investigated in these isotopes which manifest a typical nuclear shape change from spherical to prolate shapes. The peak energy, the broadening, and the deformation splitting of the isoscalar giant monopole (ISGMR) and quadrupole (ISGQR) resonances agree well with measurements. The magnitude of the peak splitting and the fraction of the energy-weighted strength in the lower peak of the ISGMR reflect the nuclear deformation. The experimental data on ISGMR, ISGDR, and ISGQR are consistent with the nuclear-matter incompressibility $K \simeq 210-230$ MeV and the effective mass $m^*_0/m \simeq 0.8-0.9$. However, the high-energy octupole resonance (HEOR) in $^{144}$Sm seems to indicates a smaller effective mass, $m^*_0/m \simeq 0.7-0.8$. A further precise measurement of HEOR is desired to determine the effective mass.

Women's Surreptitious Vocations : Policies And Women Policy-Makers On English Adult Education 1910 - 1975
Creators: name: Hughes, Constance
Publisher: name: London South Bank University
Year: 1989

description: This thesis analyses policy on English adult education for women from 1910 - 1975. I argue that policy concentrates on gender, class and age, although this is often not stated explicitly. Inspite of its claims to being non-vocational, and recreational and occupying leisure time, I show that, to a large extent adult education policy was intended to complement women's vocation as homemakers and preservers of home life as well as sometimes their paid work in servicing others. I suggest that adult education upholds the dominant ideology of domesticity for women, despite the fact that practice has not always accorded with this view. Hence I argue that adult education provides for the surreptitious vocational training of women. I also indicate that adult education provision for women largely mirrors the debates and practices around the school curriculum for girls. I analyse the situation whereby middle-class women, albeit in a minority to men, had a vocation as unpaid nominees on nationally appointed committees or as elected or co-opted members in local government to make or endorse policy decisions which had implications for unpaid vocations of working-class women. I examine the relationship between national and local policy to draw out the links, differences and processes of communication and influence between the two. As examples of national/local interaction I take three key policy changes in the London service, that is the establishment of women's institutes in 1913, their abolition in 1957 and issues of equality which arose during the gathering of evidence to the Russell Committee convened in 1969. I provide a feminist critique of the official history of adult education policy from 1910 to 1975 to discover the relationship between the vocation of women as policy-makers and the insistence on domestic vocations for women students.

description: The Floquet theorem allows to reformulate periodic time-dependent problems such as the interaction of a many-body system with a laser field in terms of time-independent, field-dressed states, also known as Floquet states. If this was possible for density functional theory as well, one could reduce in such cases time-dependent density functional theory to a time-independent Floquet density functional theory. We analyze under which conditions the Floquet theorem is applicable in a density-functional framework. By employing numerical {\em ab initio} solutions of the interacting time-dependent Schrödinger equation with time-periodic external potentials we show that the exact effective potential in the corresponding Kohn-Sham equation is {\em not} unconditionally periodic. Whenever several Floquet states in the interacting system are involved in a physical process the corresponding Hartree-exchange-correlation potential is not periodic with the external frequency only. Using an analytically solvable example we demonstrate that, in general, the periodicity of the time-dependent Kohn-Sham Hamiltonian cannot be restored by choosing a different initial state. Only if the external periodic potential is sufficiently weak such that the initial state of the interacting system evolves adiabatically to a single, field-dressed state, the resulting Kohn-Sham system admits the application of the Floquet theorem.
