Wave turbulence of a rotating array of quantized vortices in the T → 0 temperature limit
No full textThe dynamics of quantized vortices in the zero temperature limit is currently of great interest, particularly in the case of the Fermi superfluid He-B. Here we study wave turbulence, generated by the librating motion of a rotating cylindrical container filled with He-B, in the limit of vanishing viscous forces at temperatures . The polarization of the quantized vortices with respect to the axis of rotation is measured using non-invasive NMR techniques. We observe a decrease of the polarization when the librating motion is started, and a two-stage relaxation process when the modulation of the rotation velocity is stopped. The first relaxation process is associated with the dissipation of large-scale flow stored in inertial waves and the solid body rotation of the vortex array. From the decay of these energy reservoirs we determine the rate of energy dissipation of large-scale flow. The later second process is related to the relaxation of Kelvin waves on individual vortices. This process is monitored by the recovery of the polarization. The existence of a Kelvin wave cascade at the lowest temperatures is currently a central open question. We supply some evidence for the cascade
Design and Analysis of a Distributed TRIC concept Seamless Smart Morphing Wing
No full textThis thesis embarked upon establishing and validating a design process to build and control a distributed TRIC concept seamless smart morphing wing to achieve simultaneous load alleviation, flutter suppression and drag minimization capabilities. A novel aeroelastic simulation tool was built to carry out composite wing skin optimization, with prototype testing carried out to design a flexible connection between modules. The work output was a fully built morphing wing which was successfully tested in the TU Delft Open Jet Facility. Control of the wing was partially made feasible through the development of a surrogate model of the system which was also validated with DIC testing.https://www.youtube.com/watch?v=SdagIiYRWyA&t=1s Smart-X Alpha DemonstratorAerospace Engineerin
Orthodox parish website as supertext
No full textРабота выполнена в русле развития функциональной стилистики. В исследовании анализируются тексты, расположенные на сайтах православных приходов. В диссертации применяется категориально-текстовой метод, разработанный в рамках школы лингвокультурологии и стилистики УрФУ Т. В. Матвеевой. Развивается идея о том, что религиозный текст на сайте является единицей сверхтекста. Для анализа выбраны категории темы, локальности и темпоральности. В ходе исследования автор заключает, что рассматриваемые тексты обладают содержательной целостностью, ограничены локально и темпорально, что соотносится с признаками сверхтекста. Проведенный анализ позволяет сделать вывод о том, что тексты на официальных сайтах приходов являются частями сверхтекста, подчиненного конструктивному принципу прототекстуальности и сохраняющему в той или иной степени черты религиозного стиля.The work is carried out in line with the development of functional stylistics. The study analyzes the texts located on the websites of Orthodox parishes. The thesis applies the categorical-textual method developed within the school of linguoculturalism and stylistics of UrFU by T. V. Matveeva. The idea that the religious text on the website is a unit of supertext is developed. The categories of theme, locality and temporality are chosen for the analysis. In the course of the study the author concludes that the texts in question have a substantive integrity, limited locally and temporally, which correlates with the signs of the supertext. The analysis carried out allows us to conclude that the texts on the official websites of parishes are parts of the supertext, subordinate to the constructive principle of prototextuality and preserving the features of religious style to a greater or lesser extent
Pelevin’s Trinity in the novel “t”: author – protagonist – reader
No full textThe article attempts to interpret Pelevin's artistic strategy in the novel "T" by exploring its subject organization and addressing the key problems of the author, the protagonist, and the reader as they are seen by the researcher. The article analyzes the peculiarities of constructing the narrative reality in the novel "T", and goes on to discuss Pelevin's philosophic models of the development of the humankind, and the emergence of his new anthropology
Exponential stability of solutions to nonlinear time-varying delay systems of neutral type equations with periodic coefficients
No full textWe consider a class of nonlinear time-varying delay systems of neutral type differential equations with periodic coefficients in the linear terms,
d/dt y(t) = A(t)y(t) + B(t)y(t - τ(t)) + C(t) d/dt y(t - τ(t))
+ F(t, y(t), y(t - τ(t)), d/dt y(t - τ(t))),
where A(t), B(t), C(t) are T-periodic matrices, and
∥F(t, u, v, w)∥ ≤ q1∥u∥ + q2∥v∥ + q3∥w∥, q1, q2, q3 ≥ 0, t > 0.
We obtain conditions for the exponential stability of the zero solution and estimates for the exponential decay of the solutions at infinity.Mathematic
Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.
No full textIFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells
Measuring industry-science links through inventor-author relations: A profiling method
No full textIn this pilot study we examine the performance of text-based profiling in recovering a set of validated inventor-author links. In a first step we match patents and publications solely based on their similarity in content. Next, we compare inventor and author names on the highest ranked matches for the occurrence of name matches. Finally, we compare these candidate matches with the names listed in a validated set of inventor-author names. Our text-based profile methodology performs significantly better than a random matching of patents and publications, suggesting that text-based profiling is a valuable complementary tool to the name searches used in previous studies.innovation; industry-science links; text-based profiling;
