Explaining Intraday Momentum With Information Asymmetry
Creators: name: Parr, Matthew
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Return momentum, a temporal persistence in returns, is a heavily studied topic in the
financial markets. Gao et al. find that this momentum exists on an intraday level (2014). The first
half-hour return predicts the last half-hour return to a statistically significant degree, and trading
on this prediction results in a return above the market return. One proposed explanation for this
predictive power is the timing of informed traders’ entry into the market at the beginning and end
of the day. This study evaluates that explanation using an empirical metric to measure the
amount of informed trading. This measure of informed trading is found to not have a statistical
impact on the relationship between the first and last half-hour returns. Furthermore, probit
regression finds that informed trading does not have a statistical impact on predicting just the
sign of the last half-hour return from the sign first half-hour return. Therefore, the explanation
that the intraday momentum discovered by Gao, et al. (2014) is due to the market timing of
informed traders is not supported. Additional study is needed to identify the true cause of this
intraday momentum.

description: Noncommutative geometry, in its many incarnations, appears at the crossroad of various researches in theoretical and mathematical physics: from models of quantum space-time (with or without breaking of Lorentz symmetry) to loop gravity and string theory, from early considerations on UV-divergencies in quantum field theory to recent models of gauge theories on noncommutative spacetime, from Connes description of the standard model of elementary particles to recent Pati-Salam like extensions. We list several of these applications, emphasizing also the original point of view brought by noncommutative geometry on the nature of time. This text serves as an introduction to the volume of proceedings of the parallel session "Noncommutative geometry and quantum gravity", as a part of the conference "Conceptual and technical challenges in quantum gravity" organized at the University of Rome "La Sapienza" in September 2014.

description: After the pursuit of seventy years, the invention of polar codes indicates that we have found the first capacity-achieving coding with low complexity construction and decoding, which is the great breakthrough of the coding theory in the past two decades. In this survey, we retrospect the history of polar codes and summarize the advancement in the past ten years. First, the primary principle of channel polarization is investigated such that the basic construction, coding method, and classic successive cancellation (SC) decoding are reviewed. Second, in order to improve the performance of the finite code length, we introduce the guiding principle and conclude five design criteria for the construction, design, and implementation of the polar code in the practical communication system based on the exemplar schemes in the literature. Especially, we explain the design principle behind the concatenated coding and rate matching of polar codes in a 5G wireless system. Furthermore, the improved SC decoding algorithms, such as SC list (SCL) decoding and SC stack (SCS) decoding, etc., are investigated and compared. Finally, the research prospects of polar codes for the future 6G communication system are explored, including the optimization of short polar codes, coding construction in fading channels, polar coded modulation and HARQ, and the polar coded transmission, namely polar processing. Predictably, as a new coding methodology, polar codes will shine a light on communication theory and unveil a revolution in transmission technology.

Implication of Higgs mediated Flavour Changing Neutral Currents with Minimal Flavour Violation

description: We analise phenomenological implications of two Higgs doublet models with Higgs flavour changing neutral currents suppressed in the quark sector by small entries of the Cabibbo-Kokayashi-Maskawa matrix. This suppression occurs in a natural way since it is the result of a symmetry applied to the Lagrangian. These type of models were proposed some time ago by Branco Grimus and Lavoura. Our results clearly show that these class of models allow for new physical scalars, with masses which are reachable at the LHC. The imposed symmetry severely reduces the number of free parameters and allows for predictions. Therefore these models can eventually be proved right or eliminated experimentally.

The Galilean Type Synagogue at Huqoq, Israel
Creators: name: Burney, Jocelyn
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: One of the most exciting aspects of archaeology is the power of a single discovery
to challenge and redirect the field. For the last three years, I have been fortunate to
witness this process while working on the excavations at the ancient Jewish village of
Huqoq, Israel. Since 2012, the excavation team has uncovered high-quality mosaics in
the east aisle of the village synagogue depicting scenes from the life of Samson, a
dedicatory inscription, and a panel that may depict scenes from the books of Maccabees.
In this thesis, I survey the ways that these discoveries may affect the future study of
ancient synagogues, Jewish art, and Jewish society in late antique Galilee generally.
I have chosen to focus on two main topics. Chapter II discusses the similarities
between the Huqoq synagogue and the synagogues at Horvat ‘Ammudim, Meroth, and
Wadi Hamam, three other Galilean type synagogues that also contain mosaic floors.
Scholars previously believed that Galilean synagogues were built in the second and third
centuries CE and did not contain mosaics, a feature that emerged in the fourth century.
These four synagogues confirm that Galilean type synagogues were built after the third
century and contained mosaics. I propose that there likely are more synagogues with
similar features in the regions of Lower and Upper Eastern Galilee. Chapter III discusses
the imagery of the Huqoq mosaics, which offer insight into the apocalyptic and messianic
beliefs of Jewish communities in late antique Galilee. The chapter concludes with a
discussion of the role of mosaics within synagogues, a subject on which there is little
scholarly consensus. I propose that the purpose of synagogue mosaics should be
reconsidered in light of the redating of Galilean type synagogues. It is now apparent that
many Galilean type synagogues that do not contain mosaic floors, such as Capernaum,
Chorazin, and Nabratein, were contemporary to other synagogues that did contain
mosaics, indicating that not all Jewish communities viewed mosaics as a necessary
feature for a synagogue or a part of synagogue activity.

Building upon a pseudo algebraic blow up (previously introduced by the author) we prove a geometric rate of decay for the mass ratio towards the limiting density, with an explicit exponent of decay expressed in terms of the density of the current at the point.

Σκοπός της παρούσας έρευνας είναι η διερεύνηση της επίδρασης του διαζυγίου των γονέων στην ψυχική ευημερία των ενήλικων παιδιών τους ως προς το άγχος και την καταθλιπτική διάθεση. Επιπλέον, η παρούσα έρευνα εξετάζει το κατά πόσο παράγοντες όπως το φύλο μπορεί να έχει επίδραση στο άγχος και την καταθλιπτική διάθεση των ενήλικων παιδιών διαζευγμένων γονέων. Η παρούσα έρευνα αποτελεί μία ποσοτική συγχρονική έρευνα βασισμένη στη συμπλήρωση ερωτηματολογίου διαδικτυακά κατά την διάρκεια Μαρτίου-Απριλίου 2024. Στην έρευνα συμμετείχαν 129 άτομα, άνω των 18 ετών, άνδρες και γυναίκες, οι οποίοι απάντησαν διαδικτυακά στο ερωτηματολόγιο της έρευνας καθώς συμπλήρωσαν και τα ψυχομετρικά εργαλεία. Η βιβλιογραφική ανασκόπηση και τα αποτελέσματα της έρευνας έδειξαν πως το διαζύγιο έχει αρνητική επίδραση στην ψυχική ευημερία των ενήλικων παιδιών διαζευγμένων γονέων. Συγκεκριμένα, οι συμμετέχοντες που είχαν διαζευγμένους γονείς είχαν σημαντικά υψηλότερο δομικό άγχος και καταθλιπτική διάθεση από τους συμμετέχοντες που δεν είχαν χωρισμένους γονείς. Ως προς το καταστασιακό άγχος, δεν βρέθηκε να υπάρχει στατιστικός σημαντική διαφορά μεταξύ των δύο ομάδων. Τα ευρήματα της παρούσας έρευνας συμφωνούν με προηγούμενες έρευνες, αλλά ταυτόχρονα τονίζουν την ανάγκη για περαιτέρω διερεύνηση του θέματος.
description: Divorce is becoming an increasingly common phenomenon in the modern world, which can have several negative effects on the mental well-being of children even into adulthood. The purpose of this study is to investigate the impact of parental divorce on the mental well-being of their adult children concerning anxiety and depressive mood. Additionally, this study examines the extent to which factors such as gender may influence the anxiety and depressive mood of adult children of divorced parents. This research is a quantitative cross-sectional study based on the completion of an online questionnaire during March-April 2024. The study involved 129 participants, over 18 years old, both men and women, who responded to the online questionnaire of the study and completed psychometric tools. The literature review and the results of the study showed that divorce negatively impacts the mental well-being of adult children of divorced parents. Specifically, participants with divorced parents had significantly higher trait anxiety and depressive mood than participants without divorced parents. Concerning state anxiety, there was no statistically significant difference found between the two groups. The findings of this study align with previous research but also highlight the need for further investigation on the topic.

description: The magnetic order of the triangular lattice with antiferromagnetic interactions is described by an SO(3) field and allows for the presence of Z2 magnetic vortices as defects. In this work we show how these Z2 vortices can be fitted into a local SU(2) gauge theory. We propose simple Ansatzes for vortex configurations and calculate their energies using well-known results of the Abelian gauge model. We comment on how Dzyaloshinskii-Moriya interactions could be derived from a non-Abelian gauge theory and speculate on their effect on non trivial configurations.

description: We study the four-dimensional effective theory arising from ten-dimensional heterotic supergravity compactified on manifolds with torsion. In particular, given the heterotic superpotential appropriately corrected at $\mathcal{O}(α')$ to account for the Green-Schwarz anomaly cancellation mechanism, we investigate properties of four-dimensional Minkowski vacua of this theory. Considering the restrictions arising from F-terms and D-terms we identify the infinitesimal massless moduli space of the theory. We show that it agrees with the results that have recently been obtained from a ten-dimensional perspective where supersymmetric Minkowski solutions including the Bianchi identity correspond to an integrable holomorphic structure, with infinitesimal moduli calculated by its first cohomology. As has recently been noted, interplay of complex structure and bundle deformations through holomorphic and anomaly constraints can lead to fewer moduli than may have been expected. We derive a relation between the number of complex structure and bundle moduli removed from the low energy theory in this way, and give conditions for there to be no complex structure moduli or bundle moduli remaining in the low energy theory. The link between Yukawa couplings and obstruction theory is also briefly discussed.

description: We find very good agreement between our theoretically evaluated lifetimes of the $5d \ ^2D_{3/2}$ and $5d \ ^2D_{5/2}$ states of Cs with the experimental values reported in [Phys. Rev. A {\bf 57}, 4204 (1998)], which were earlier evinced to be disagreeing with an earlier rigorous theoretical study [Phys. Rev. A {\bf 69}, 040501(R) (2004)] and with another precise measurement [Opt. Lett. {\bf 21}, 74 (1996)]. In this work, we have carried out calculations of the radiative transition matrix elements using many variants of relativistic many-body methods, mainly in the coupled-cluster theory framework, and analyze propagation of the electron correlation effects to elucidate their roles for accurate evaluations of the matrix elements. We also demonstrate contributions explicitly from the Dirac-Coulomb interactions, frequency independent Breit interaction and lower order quantum electrodynamics (QED) effects. Uncertainties to these matrix elements due to different possible sources of errors are estimated. By combining our calculated radiative matrix elements with the experimental values of the transition wavelengths, we obtain the transition probabilities due to both the allowed and lower order forbidden channels. Adding these quantities together, the lifetimes of the above two states are determined precisely and plausible reasons for the reported inconsistencies between the earlier theoretical calculations and the experimental results have been pointed out.

description: The newspaper coverage about the desegregation of college sports provides a perspective on race and society at this time in history. This honor’s thesis discusses how the News and Observer, Daily Tar Heel and Carolina Times covered Charles Scott, the first black scholarship athlete at the University of North Carolina, during his college basketball career from 1966 to 1970. It reveals that a different emphasis was placed on Scott as an athlete, student, community leader and Olympian in the three newspapers’ coverage. The way Scott was covered in the newspapers appears to reflect the social and political climate of the time, and also provides insight about the way in which articles in each newspaper addressed race and integration. This research is also indicative of how newspaper coverage on the same subject differs depending on the perspective the paper, the audience they serve and the view of the author of the story.

description: Spectroscopic ellipsometry is a sensitive and optical model-supported quantitative tool to monitor interfaces. In this work, solid-liquid interfaces are studied using the Kretschmann-Raether configuration for biosensing applications. The interface layers support two purposes simultaneously: (i) chemical suitability for the adsorption of molecules to be detected and (ii) the optical enhancement of the signal to increase the sensitivity. Ellipsometry is not only used as a sensor but also as a quantitative measurement tool to study and understand the interface phenomena, and to develop the sensing layers for the largest possible optical sensitivity. Plasmonic and structured layers are of primary importance in terms of optical sensitivity. Layers structured both in lateral and vertical directions have been studied. Optical models based on both the transfer matrix and the finite element method were developed and used for the structural analysis where the material and geometrical derivatives are used in the inverse fitting process of the model data to the measurement. Structures utilizing plasmonic, diffraction, multilayer field enhancement, and other methods were analyzed as possible candidates for the improvement of the optical performance of the cell. Combinatorial and periodic plasmonic surface structures were developed to enhance the sensitivity of in-situ ellipsometry at solid-liquid interfaces utilizing the Kretschmann-Raether (KR) geometry. Ag$_x$Al$_{1-x}$ layers with variable compositions and Au layers with changing periods and critical dimensions were investigated to improve the performance of sensors based on the KR arrangement.

Fanon and Medicine: An Intellectual Biography
Creators: name: Cooper, Austin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: By any measure, Frantz Fanon died before his time, at the age of 36. Arguably,
Fanon also lived before his time. Born in 1925 in Martinique – at the time a French
colonial possession – Fanon moved to France in the late 1940s to study medicine,
attending Merleau-Ponty’s lectures and reading widely in philosophy, anthropology, and
literature in his spare time. From the early 1950s until his death in 1961, Fanon would
write some of the twentieth-century’s most nuanced and influential analyses of modern
racism and colonialism, all the while practicing psychiatry at public hospitals in France
and across North Africa. Tracing the contours of Fanon’s intellectual biography, this
thesis explores the ways in which Fanon’s medical training and practice informed his
groundbreaking insights into the political plight of the colonized.

description: Photons with a twisted phase front can carry a discrete, in principle unbounded amount of orbital angular momentum (OAM). The large state space allows for complex types of entanglement, interesting both for quantum communication and for fundamental tests of quantum theory. However, the distribution of such entangled states over large distances was thought to be infeasible due to influence of atmospheric turbulence, indicating a serious limitation on their usefulness. Here we show that it is possible to distribute quantum entanglement encoded in OAM over a turbulent intra-city link of 3 kilometers. We confirm quantum entanglement of the first two higher-order levels (with OAM=$\pm 1 \hbar$ and $\pm 2 \hbar$). They correspond to four new quantum channels orthogonal to all that have been used in long-distance quantum experiments so far. Therefore a promising application would be quantum communication with a large alphabet. We also demonstrate that our link allows access to up to 11 quantum channels of OAM. The restrictive factors towards higher numbers are technical limitations that can be circumvented with readily available technologies.

The Accessible Henry VI: A New Adaptation
Creators: name: Rio, Melanie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: In recent decades (i. e., in the last fifty years or so), a considerable number of enterprising theatres have risen to the challenge presented by the problematic Henry VI plays. In order to avoid fragmenting the plot, a number of companies have chosen to mount all three plays at once. Parts 1, 2, and 3 have been presented in rotating repertory, have been condensed into two plays, and have undergone a number of creative cuts in order to be marketable to a theatre-going audience. However, these mammoth productions, most often mounted by theatrical giants such as the Royal Shakespeare Company, are both expensive to produce and taxing for an audience to watch, generally being (in total) much longer than “the norm of two or three hours” which “has been one of the most durable conventions of the Western theater”4 since the days of Shakespeare himself. These “theatrical marathons”5 provide a unique experience, but their demands are daunting, and it is only an exceptionally well-staffed and well-funded theatre that may even consider producing one in the first place.
Unfortunately, these requirements – demanding of audience and company alike – leave a wide gap in the viewership of the Henry VI trilogy. There are two principal groups which, because of the limitations of the plays in their current, various forms, are denied access to them: companies with a fraction of the RSC’s budget and resources, and viewers unwilling or unable to sit through six to nine hours of theatre. The Henry VI cycle will remain predominantly inaccessible until an adaptation of more reasonable length and production requirements is available. This is the ultimate goal of the ‘accessible’ Henry VI: to condense all three parts of William Shakespeare’s Henry VI trilogy into one play, which can be performed in the same amount of time, using the same amount of resources, as any of Shakespeare’s other individual works.
There is, of course, an accompanying caveat: one must endeavor to make the Henry VI trilogy more widely performable and accessible without compromising the integrity of the original works. The Henry VI plays are certainly worth performing, and though it presents a considerable challenge, I believe it is possible to condense them in such a way that the merits of the works are preserved, while some of the more problematic elements are reduced or removed. This endeavor presents, in fact, a unique opportunity: to exhibit the most exemplary aspects of the Henry VI plays and create a more performable script which does not suffer from the same shortcomings responsible for the plays’ original fall from popularity. It is a challenging project, to be sure, but when one considers the possibility of a free-standing, readily operative Henry VI, the risk of wasted time and effort seems small by comparison.

description: We consider the synthesis of distributed implementations for specifications in Prompt Linear Temporal Logic (PROMPT-LTL), which extends LTL by temporal operators equipped with parameters that bound their scope. For single process synthesis it is well-established that such parametric extensions do not increase worst-case complexities. For synchronous systems, we show that, despite being more powerful, the distributed realizability problem for PROMPT-LTL is not harder than its LTL counterpart. For asynchronous systems we have to consider an assume-guarantee synthesis problem, as we have to express scheduling assumptions. As asynchronous distributed synthesis is already undecidable for LTL, we give a semi-decision procedure for the PROMPT-LTL assume-guarantee synthesis problem based on bounded synthesis.

Normal Modes of the Structural Connectome

Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Division of the human cortex into distinct regions is of high importance to neuroscientific inquiry. Fully-automated, multi-modal schemes of achieving such parcellation on an individual subject basis are particularly advantageous, however difficulties in inter-modal and inter-subject registration of brain images, as well as obstacles in preserving group-level correspondence of individual parcellation maps have slowed progress in this area. In parallel, there exists a relative dearth of data-driven parcellation schemes that incorporate high resolution structural connectivity metrics; the majority of widely-accepted parcellation maps in the literature have primarily used functional connectivity. Here, a fully data-driven, automated routine based on structural geometry and connectivity which achieves subject-specific cortical parcellation maps while maintaining group-level correspondence of maps is presented and optimized. Using high resolution white matter surface meshes and advanced fiber tracking techniques, a novel vertex-wise structural connectivity graph is constructed for each of 10 unrelated subjects, and the first k eigenvectors of the Laplacian Matrix of the graph's adjacency matrix are calculated. These eigenvectors represent the steady-state modes of vibration of the manifold described by this graph, and thus provide subject-specific maps of modes of connectivity in white matter. In order to obtain parcellations at varying levels of coarseness of the cortex from these eigenvectors, hierarchical agglomerative clustering is then performed on the surface mesh, where each vertex's feature vector is its profile in spectral space. Further, a multi-layer graph of all subjects is constructed, and individual parcellations with group level correspondence are obtained by agglomerative clustering of the eigenvectors of the laplacian matrix of the multi-layer graph.

description: This work reports on the synthesis and characterization of a new type of electrospun magnetic nanofibers (MNFs), and their application for degradation of organic pollutants using remote magnetic inductive heating. We describe a simple protocol combining a fast (app. 5 min) synthesis of MnFe\textsubscript{2}O\textsubscript{4} magnetic nanoparticles (MNPs) by sonochemical route, optimized for inductive heating, with their subsequent incorporation in electrospun MNFs composed of polyacrylonitrile (PAN) nanofibers. The resulting multifunctional MNFs (average diameter $ϕ= 760 \pm 150$ nm) contain up to $\approx 30%$wt. of the MNPs. The composite showed superhydrophobic behaviour ($θ_c = 165^\circ$) and a band gap value of 1.75 eV. We found that the presence of MNPs embedded into the polymeric nanofibers modify the exothermic and the glass transitions temperatures compared with pure PAN nanofibers, suggesting a strong attachment between MNPs and polymeric chains. The MNFs could be remotely activated by alternating magnetic fields (AMF, $f = 200-800$ kHz, $H_0 = 10-36$ kA/m) for accelerating the catalytic reactions of the organic dye methylene blue (MB). A remarkable stability of the MNFs against degradation under extreme pH conditions ($380%$ in the presence of hydrogen peroxide under AMFs, attributed to Fe\textsuperscript{2+}/\textsuperscript{3+} and Mn\textsuperscript{2+}/\textsuperscript{3+}/\textsuperscript{4+} active centers on the surface of the MNP/MNFs observed from XPS data. The capacity of these materials for magnetic remote activation appeals catalytic applications under conditions of darkness or restrained access, where no photocatalytic reactions can be achieved.

The ASTE C$^{18}$O data are combined with our previous SMA C$^{18}$O data, which show a $r \sim$300-AU scale Keplerian disk around the protostellar binary system. The C$^{18}$O maps show a $\sim$20000-AU scale protostellar envelope surrounding the central Keplerian circumbinary disk. The envelope exhibits a northeast (blue) - southwest (red) velocity gradient along the minor axis, which can be interpreted as a dispersing gas motion with an outward velocity of 0.3 km s$^{-1}$, while no rotational motion in the envelope is seen. In addition to the envelope, two $\lesssim$4000 AU scale, high-velocity ($\gtrsim$1.3 km s$^{-1}$) redshifted $^{13}$CO and CS emission components are found to $\sim$40$^{\prime\prime}$ southwest and $\sim$20$^{\prime\prime}$ west of the protostellar binary. These redshifted components are most likely outflow components driven from the neighboring protostellar source L1551 IRS 5, and are colliding with the envelope in L1551 NE. The net momentum, kinetic and internal energies of the L1551 IRS 5 outflow components are comparable to those of the L1551 NE envelope, and the interactions between the outflows and the envelope are likely to cause the dissipation of the envelope and thus suppression of the further growth of the mass and mass ratio of the central protostellar binary in L1551 NE.

description: The re-use of research data is an integral part of research practice in the social and economic sciences. To find relevant data, researchers need adequate search facilities. However, a comprehensive, thematic search for research data is made more difficult by inconsistent or missing semantic indexing of data at the level of social science concepts (e.g., representing the theory language). Either the data is not documented at a granular level, or primary investigators use their ad-hoc terminology to describe their data. Consequently, researchers have to make great efforts to find relevant or comparable data. From the user's perspective, the lack of theory language in data documentation impedes effective data searches and thus significantly limits the research potential of existing data collections. Because there is currently no semantic model for indexing the data content, the specific challenge for improving data search lies in establishing concept-based indexing of research data. Research infrastructures need technology for the harmonized semantic indexing of their research data. The LORD concept registry aims at closing this gap by developing a registry of sociological and economic concepts and, following the FAIR principles, making this concept registry generally available to the scientific community. As a first step, we developed a basic data model for the Concept Registry using United Modeling Language (UML). All links between are created and managed in the form of so-called RDF triples. An annotation application allows for linking specific questions/variables to concepts. The application also includes the two SKOS-compliant thesauri, "Thesaurus Social Sciences" (TheSoz) and "Standard Thesaurus Economics" (STW) but could be extended to other resources like ELSST. We illustrate the application of the LORD concept registry with examples from three large-scale survey programmes (German Socio-Economic Panel, German General Social Survey, National Academics Panel Study). The initial focus is on variables and questions with overlapping content in the three survey programmes, as they form a sound basis for cross-linking with concepts.

description: We present a study on the magnetic behavior of dextran-coated magnetite nanoparticles (DM NPs) with sizes between 3 and 19 nm, synthesized by hydrothermal-assisted co-precipitation method. The decrease of saturation magnetization ($M_s$) with decreasing particle size has been modeled by assuming the existence of a spin-disordered layer at the particle surface, which is magnetically dead. Based on this core-shell model and taking into account the weight contribution of the non-magnetic coating layer (dextran) to the whole magnetization, the dead layer thickness ($t$) and saturation magnetization $M_s$ of the magnetic cores in our samples were estimated to be $t = 6.8~\mathrmÅ$ and $M_s = 98.8~\mathrm{emu/g}$, respectively. The data of $M_s$ were analyzed using a law of approach to saturation, indicating an increase in effective magnetic anisotropy ($K_{eff}$) with decreasing particle size as expected from the increased surface/volume ratio in small MNPs. The obtained $K_{eff}$ values were successfully modeled by including an extra contribution of dipolar interactions due to the formation of chain-like clusters of MNPs. The surface magnetic anisotropy ($K_s$) was estimated to be about $K_s = 1.04\times10^5~\mathrm{J/m^3}$. Our method provides a simple and accurate way to obtain the $M_s$ core values in surface-disordered MNPs, a relevant parameter required for magnetic modeling in many applications.

description: We obtain an explicit solution for the stationary state populations of a dissipative Fano model, where a discrete excited state is coupled to a continumm set of states; both excited set of states are reachable by photo-excitation from the ground state. The dissipative dynamic is described by a Liouville equation in Lindblad form and the field intensity can take arbitrary values within the model. We show that the continuum states population as a function of laser frequency can always be expressed as a Fano profile plus a Lorentzian function with effective parameters whose explicit expressions are given in the case of a closed system coupled to a bath as well as for the original Fano scattering framework. Although the solution is intricate, it can be elegantly expressed as a linear transformation of the kernel of a $4\times 4$ matrix which has the meaning of an effective Liouvillian. We unveil key notable processes related to the optical nonlinearity and which had not been reported to date: electromagnetic induced-transparency, population inversions, power narrowing and broadening, as well as an effective reduction of the Fano asymmetry parameter.

description: Some extensions of the Standard Model suggest existence of vectorlike fermions whose mass $M$ can be by up to several orders of magnitude larger than the electroweak scale $v$, and with the Higgs mechanism providing only a small part $m$ of this mass that is a fraction of $v$. It is shown that in a certain range of the parameters $m$ and $M$ there exist stable globules of degenerate fermionic matter made from the lighter of the neutral vectorlike leptons (superheavy neutrinos) with a number density much larger than $m_h \, v^2$, with $m_h$ being the Higgs boson mass. The stability is due to the deformation of the Higgs field inside the globule to values greatly exceeding $v$. The globules are absolutely stable if the lighter of the vectorlike neutrinos is stable and can be (a part of) the dark matter.

description: Edinburgh is internationally renowned for its festivals, with some now celebrating their 76th year. The workforce in the sector is predominantly composed by women, nevertheless, little research has been undertaken regarding gender equality and conditions for women working in Edinburgh’s festivals. This postdisciplinary PhD, underpinned by a feminist paradigm and qualitative methodology, studies the extent to which women working in Edinburgh’s festivals sector achieve leadership positions; and the reasons underpinning this. The research aims to understand the issues and challenges faced by women working in Edinburgh’s festivals. It investigates the influence of society and culture. The research also considers gender stereotypes, and to what extent gendered roles are important to the way women perceive themselves. Through a feminist lens, this research considers festival leadership, and what skills are required in this setting.
The significance of this research is both within the topic and its feminist methodology. Semi structured interviews with visual methods, specifically photo-voice, were employed. These were undertaken with women who have worked in Edinburgh’s festivals. Research findings indicate that women experience a series of challenges. Some are caused by the nature of festivals, being temporary in nature, timebound, and with busy schedules. Others are a consequence of gender stereotypes, and gendered roles. Moreover, findings around festival leadership revealed the skills required in this role, and the value of a collective and genderless approach.
The conclusions emerging from this PhD study make an important contribution to knowledge and theory building in festival leadership, women leadership, and gender (in)equalities in festivals. Key findings confirm social expectations society has on women seen as primary caregivers. Women experience several gender inequalities, as well as Tokenism, Role Congruity, and the Queen Bee Phenomenon. These findings contribute to wider literature in event, tourism, and hospitality management, advancing the understanding of issues relating to equality, diversity, and inclusion (EDI), and presenting a new understanding of the key skills required for festival leaders.
What's in a Home?: The Liminal Culture of Asian Indian Americans

description: Jhumpa Lahiri’s writing speaks to this world and gives voice to this generation. Her
stories are raw and honest; they bring to life the dual cultural lifestyle the second generation
lives. She mixes the American landscape—both cultural and physical—with the Indian. For
example, while her stories are almost always located in New England, they most often take place
in suburban or urban neighborhoods that could be anywhere. The overarching idea is that these
cultural dilemmas happen everywhere, within these common houses and families in the U.S. I
chose to use her narratives as a way to investigate my own—as a way to answer some of the
questions I have about growing up in this generation. Crafting a performance enabled me to
engage with Jhumpa Lahiri’s text while keeping the focus on my personal experiences. I would
be the one on stage, breaking apart what I knew of Indian immigration and Lahiri’s stories and
filtering it through my own experiences in order to better understand my history and my identity
as an Indian American. I hoped to recognize how second generation Indian Americans reckon
with the stereotypes and misrepresentations that come with growing up in a primarily white-
American society as well as form a better understanding of my cultural identity, with particular
regard to the history of Indian immigration in the U.S. and the cultural community of second
generations that practice a dual Indian American culture.

description: GaAs/AlGaAs quantum dots grown by in-situ droplet etching and nanohole infilling offer a combination of strong charge confinement, optical efficiency, and spatial symmetry required for polarization entanglement and spin-photon interface. Here we study spin properties of such dots. We find nearly vanishing electron $g$-factor ($g_e<0.05$), providing a route for electrically driven spin control schemes. Optical manipulation of the nuclear spin environment is demonstrated with nuclear spin polarization up to $60\%$ achieved. NMR spectroscopy reveals the structure of two types of quantum dots and yields the small magnitude of residual strain $ε_b<0.02\%$ which nevertheless leads to long nuclear spin lifetimes exceeding 1000 s. The stability of the nuclear spin environment is advantageous for applications in quantum information processing.
