Geodesics and resonances of the Manko-Novikov spacetime
Get PDFThesis (MSc)--Stellenbosch University, 2013.ENGLISH ABSTRACT: In this thesis I study compact objects described by the Manko-Novikov spacetime. The Manko-
Novikov spacetime is an exact solution to the Einstein Field Equations that allows objects to be
black hole-like, but with a multipole structure di erent from Kerr black holes. The aim of the
research is to investigate whether we will observationally be able to tell these bumpy black holes,
if they exist, apart from traditional Kerr black holes. I explore the geodesic motion of a test
probe in the Manko-Novikov spacetime. I quantify the motion using Poincar e maps and rotation
curves. The Manko-Novikov spacetime admits regions with regular motion as well as regions with
chaotic motion. The occurrence of chaos is correlated with orbits for which the characteristic
frequencies are resonant. The new result presented in this thesis is a global characterisation
of where resonances and thus chaos are likely to occur for all orbits. These calculations are
performed in the Kerr spacetime, from which I obtain that low order resonances occur within
20 Schwarzschild radii (or 40M) of the compact object with mass M. By the KAM theorem,
the occurrence of chaos is therefore limited to this region for all small perturbations from Kerr.
These resonant events will be measurable in the Galactic Centre using eLISA. This con nement
of low order resonances indicates that the frequency values of orbits of radii well outside of
20 Schwarzschild radii can be approximated using canonical perturbation theory.AFRIKAANSE OPSOMMING: In hierdie tesis word kompakte voorwerpe bestudeer soos omskryf deur die Manko-Novikov
ruimtetyd. Die Manko-Novikov ruimtetyd is 'n eksakte oplossing van die Einstein Veldvergelykings.
Die Manko-Novikov ruimtetyd formuleer gravitasiekolk-tipe voorwerpe waarvan die
veelpool-struktuur afwyk van die tradisionele Kerr gravitasiekolk-struktuur. Die oogmerk van die
navorsing is om vas te stel of ons met behulp van waarnemings hierdie bonkige gravitasiekolke van
die tradisionele Kerr gravitasiekolke kan onderskei. Ek ondersoek die geodetiese beweging van 'n
toetsmassa in die Manko-Novikov ruimtetyd. Die beweging word gekwanti seer met behulp van
Poincar e afbeeldings en rotasiekrommes. In die Manko-Novikov ruimtetyd identi seer ek gebiede
waarbinne re elmatige beweging voorkom asook gebiede waarbinne chaotiese bane voorkom. Die
ontstaan van chaos word geassosieer met bane waarvan die fundamentele frekwensies resonant is.
'n Nuwe resultaat wat in hierdie tesis voorgehou word behels 'n globale karakterisering wat aandui
waar resonansies en dus chaos na alle waarskynlikheid voorkom. Laasgenoemde berekeninge
word vir die Kerr ruimtetyd uitgevoer. Hierdeur toon ek alle lae orde resonansies kom voor binne
20 Schwarzschild radii (of 40M) vanaf die kompakte voorwerp met mass M. Die KAM Stelling
bepaal dan dat vir alle klein steurings toegepas op die Kerr ruimtetyd die voorkoms van chaos
beperk sal wees tot bogenoemde gebied. Die resonansies binne hierdie gebied sal deur eLISA in
die sentrum van die melkwegstelsel gemeet kan word. Hierdie beperking van lae orde resonansies
tot 'n sekere afstand vanaf die kompakte voorwerp verseker dat die frekwensies van bane wat
buite hierdie gebied val, akkuraat deur kanoniese steuringsteorie bepaal kan word

Different fear states engage distinct networks within the intercalated cell clusters of the amygdala
Get PDFAlthough extinction-based therapies are among the most effective treatments for anxiety disorders, the neural bases of fear extinction remain still essentially unclear. Recent evidence suggests that the intercalated cell masses of the amygdala (ITCs) are critical structures for fear extinction. However, the neuronal organization of ITCs and how distinct clusters contribute to different fear states are still entirely unknown. Here, by combining whole-cell patch-clamp recordings and biocytin labeling with full anatomical reconstruction of the filled neurons and ultrastructural analysis of their synaptic contacts, we have elucidated the cellular organization and efferent connections of one of the main ITC clusters in mice. Our data showed an unexpected heterogeneity in the axonal pattern of medial paracapsular ITC (Imp) neurons and the presence of three distinct neuronal subtypes. Functionally, we observed that the Imp was preferentially activated during fear expression, whereas extinction training and extinction retrieval activated the main ITC nucleus (IN), as measured by quantifying Zif268 expression. This can be explained by the IPSPs evoked in the IN after Imp stimulation, most likely through the GABAergic monosynaptic innervation of IN neurons by one subtype of Imp cells, namely the medial capsular-projecting (MCp)-Imp neurons. MCp-Imp neurons also target large ITC cells that surround ITC clusters and express the metabotropic glutamate receptor 1_. These findings reveal a distinctive participation of ITC clusters to different fear states and the underlying anatomical circuitries, hence shedding new light on ITC networks and providing a novel framework to elucidate their role in fear expression and extinction. © 2011 the authors
Tres documentos inéditos para la historia de la guerra de reconquista inca. Las declaraciones de Lorenzo Manko y Diego Yuqra Tikona, servidores de Manko Inka Yupanki y de Francisco Waman Rimachi, testigos presenciales de los sucesos de 1533 a 1558
No full textRésumé
Dans cet article sont publiées les déclarations de trois témoins oculaires des événements de 1533 à 1558, c’est-à-dire depuis l’entrée de Manko Inka Yupanki à Cusco, avec ses alliés espagnols, jusqu’à la “sortie” de Yauki Sayri Thupa, — un de ses enfants — en 1558, sur la pression militaire et diplomatique du Marquis de Cañete. Ces témoignages directs, confrontés avec d’autres contemporains, constituent de nouveaux éléments inédits pour éclairer la version donnée par les sources espagnoles de cette époque ; ils font connaître également, et presque en détail, les négociations du vice-roi Marquis de Cañete, lequel se proposait d’en finir pacifiquement avec la résistance héroïque de Vilcabamba, ainsi que la prudence Inca pour déjouer ce plan et éviter les dangers d’une guerre contre ce dernier réduit du Tawantinsuyo.
Il ressort de ces témoignages, comparés avec d’autres fiables que nous avons consultés, la mise en question de la vérité sur la succession de Sayri Thupa à la mort de son père, Manko Inka, et la possibilité que le jeune auki ait simulé cette fonction par le truchement d’un artifice politique de la Cour de Vilcabamba.Resumen
Se publican en este artículo las declaraciones de tres testigos presenciales de los sucesos de 1533 a 1558, es decir desde la entrada de Manko Inka Yupanki al Cusco, con sus aliados españoles, hasta la “salida” del auki Sayri Thupa, — uno de sus hijos — en 1558, ante la presión militar y diplomática del Marqués de Cañete.
Estos testimonios directos, confrontados con otros coetáneos, constituyen nuevos e inéditos elementos de juicio para aclarar la versión de las fuentes hispanas de estos años y para conocer casi en detalle las negociaciones del virrey Marqués de Cañete, que se proponía acabar pacíficamente con la resistencia heroica de Vilcabamba, y la cautela Inca para burlar este propósito y evitar los peligros de una guerra contra este último reducto del Tawantinsuyo.
De estos testimonios compulsados con otros confiables que se citan, resulta cuestionada la verdad sobre la sucesión de Sayri Thupa a la muerte de su padre Manko Inka y la posibilidad que este auki simulara este cargo como un ardid político de la Corte de Vilcabamba.Guillén Guillén Edmundo.

PROJECTING VISUALISATION OF DIDACTIC OBJECTS AS A DETERMINANT OF STUDENTS’ DEVELOPMENT
No full textThe paper investigates the pedagogic potential of visualization phenomenon. The research is aimed at substantiating the didactic instruments implementation for raising the effectiveness of knowledge acquisition. The research methodology basis incorporates the cognitive visualization ideas along with the theory and technology of instrumental didactics.The projection process, viewed as the mechanism and outcome of the human mind activity, is regarded as a pedagogic means for visualization and modeling of educational content. For organizing and controlling the above process, the author introduces a regulative concept, referred to as the programming basis of a human consciousness directing the cognition processes and reflecting the outcomes of teaching activity.The development trends of pedagogic principle of visibility are demonstrated; the projective regulative visualization of didactic objects being outlined. The author describes the anthropological and socio-cultural background of visibility principle and suggests the complex of didactic visual means for solving the pedagogic tasks

dynamics. Due to the small mass difference of the N and N systems, the sizable coupling strength of
the N ↔ N processes constitutes a crucial element in the determination of the N interaction. In
this letter we present the most precise measurements on the interaction of p pairs, from zero relative
momentum up to the opening of the N channel. The correlation function in the relative momentum
space for p ⊕ p pairs measured in high-multiplicity triggered pp collisions at √s = 13 TeV at the
LHC is reported. The opening of the inelastic N channels is visible in the extracted correlation function
as a cusp-like structure occurring at relative momentum k∗ = 289 MeV/c. This represents the first direct
experimental observation of the N ↔ N coupled channel in the p system. The correlation function
is compared with recent chiral effective field theory calculations, based on different strengths of the
N ↔ N transition potential. A weaker coupling, as possibly supported by the present measurement,
would require a more repulsive three-body NN interaction for a proper description of the in-medium
properties, which has implications on the nuclear equation of state and for the presence of hyperons
inside neutron stars
Nemoura undetermined
No full textNemoura sp. Lənkəran region: 2: 1♀ (HNHM); Gəncə-Qazax region: 38 : 1♀ (MM); 40: 2♀ (HNHM); 43: 1♀ (LMEE). Remarks. These female Nemoura specimens were collected without males, and their specific identity are uncertain. However, the females from Göygöl and Gədəbəy (sites 38, 40, 43) are probably N. irani, while the single female from Azərüd (site 2) may belong to N. irani, or N. caspica Aubert, 1964, another Alborz endemic.Published as part of Murányi, Dávid, Manko, Peter, Kovács, Tibor, Vinçon, Gilles, Žiak, Matej, Kerimova, Ilhama G., Snegovaya, Nataly Yurievna & Oboňa, Jozef, 2021, Review and contribution to the stonefly (Insecta: Plecoptera) fauna of Azerbaijan, pp. 58-80 in Zootaxa 4975 (1) on page 73, DOI: 10.11646/zootaxa.4975.1.2, http://zenodo.org/record/480461
