description: In this article, a new perspective for obtaining the magnetic evolution of $π-π$ scattering lengths in the frame of the linear sigma model is presented. When computing the relevant one-loop diagrams that contribute to these parameters, the sum over Landau levels --emerging from the expansion of the Schwinger propagator-- is handled in a novel way that could also be applied to the calculation of other magnetic-type corrections. Essentially, we have obtained an expansion in terms of Hurwitz Zeta functions. It is necessary to regularize our expressions by an appropriate physical subtraction when $|qB| \rightarrow 0$ ($q$ the meson charge and $B$ the magnetic field strength). In this way, we are able to interpolate between the very high magnetic field strength region, usually handled in terms of the Lowest Landau Level (LLA) approximation, and the weak field region, discussed in a previous paper by some of us, which is based on an appropriate expansion of the Schwinger propagator up to order $|qB|^{2}$. Our results for the scattering lengths parameters produce a soft evolution in a wide region of magnetic field strengths, reducing to the previously found expressions in both limits.

Examining Differences in Depression and Anxiety Between Racial and Ethnic Minority Athletes and White Athletes Following Anterior Cruciate Ligament Reconstruction
Creators: name: Brown, T'era
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: While anterior cruciate ligament reconstruction (ACLR) is standard practice following anterior cruciate ligament tears, racial disparities may affect outcomes following surgical intervention. These disparities may cause differences in psychosocial responses, significantly influencing athletes' return to activity. The aim of this study was to examine differences in anxiety and depression symptoms in white versus racial and ethnic minority athletes following ACLR. A cross-sectional study was conducted using a demographic questionnaire, patient health questionnaire-8 (PHQ-8), and general anxiety disorder-7 (GAD-7). Mann-Whitney U tests were used to examine between-group differences in depression and anxiety symptoms. No significant differences in racial and ethnic status and mental health symptoms were found. Stigma surrounding mental health in racial and ethnic minority groups may have contributed to observed results. Understanding the relationship between race and ethnicity, social determinants of health, ACLR, and mental health could lead to positive rehabilitative outcomes and successful return to activity following ACLR.

description: The classical Hall effect, the traditional means of determining charge-carrier sign and density in a conductor, requires a magnetic field to produce transverse voltages across a current-carrying wire. We show that along curved paths -- $\mathrm{\textit{without}}$ any magnetic field -- geometry alone can produce nonlinear transverse potentials that reflect the charge-carrier sign and density. We demonstrate this effect in curved graphene wires where the transverse potentials are consistent with the doping and change polarity as we switch the carrier sign. In straight wires, we measure transverse potential fluctuations with random polarity demonstrating that the current follows a complex, tortuous path. This geometrically-induced potential offers a sensitive characterization of inhomogeneous current flow in thin films.

Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: A brief overview of various approaches to the optical-model description of nuclei is presented. A survey of some of the formal aspects is given which links the Feshbach formulation for either the hole or particle Green's function to the time-ordered quantity of many-body theory. The link between the reducible self-energy and the elastic nucleon-nucleus scattering amplitude is also presented using the development of Villars. A brief summary of the essential elements of the multiple-scattering approach is also included. Several ingredients contained in the time-ordered Green's function are summarized for the formal framework of the dispersive optical model (DOM). Empirical approaches to the optical potential are reviewed with emphasis on the latest global parametrizations for nucleons and composites. Various calculations that start from an underlying realistic nucleon-nucleon interaction are discussed with emphasis on more recent work. The efficacy of the DOM is illustrated in relating nuclear structure and nuclear reaction information. Its use as an intermediate between experimental data and theoretical calculations is advocated. Applications of the use of optical models are pointed out in the context of the description of nuclear reactions other than elastic nucleon-nucleus scattering.

Year: 2024

description: Different actors around the world have adopted the ‘smart city’ label to signify various interventions that utilize the latest technologies to solve urban problems. Existing critical smart city scholarship tends to focus on well-known technology companies in well-known places. This research, however, neglects a range of other actors that influence smart city projects and help bring smart cities into existence. In this thesis, I examine two ordinary, medium-sized municipalities in Colorado involved in smart city projects, and I employ assemblage theory to highlight the diverse actors that shape smart city efforts. In particular, this thesis draws attention to the powers that municipal governments have to shape smart city projects. I argue that equity can and should be foregrounded in smart city projects and that municipal governments are uniquely positioned to further equity-related smart city goals.

description: We consider domain walls embedded in curved backgrounds as an approximation for braneworld scenarios. We give a large class of new exact solutions, exhausting the possibilities for describing one and two walls for the cases where the curvature of both the bulk and the wall is locally constant. In the case of two walls, we find solutions where each wall has positive tension. An interesting property of these solutions is that the curvature of the walls can be much smaller than the tension, leading to a significant cancellation of the effective cosmological constant, which however is still much larger than the observational limits. We further discuss some aspects of inflation in models based on wall solutions.

description: The Poincare'-Dulac normal form of a given resonant system is in general non unique; given a specific normal form, one would like to further reduce it to a simplest normal form. In this note we give an algorithm, based on the Lie algebraic structure of the set of normal forms, to obtain this. The algorithm can be applied under some condition, non generic but often met in applications; when applicable, it only requires to solve linear equations, and is more powerful than the one proposed in previous work by the same author [Lett. Math. Phys. 42, 103-114; and Ann. I.H.P. 70, 461-514].

Black hole entropy from Poisson brackets (demystification of some calculations)

description: Recently it has been suggested by S. Carlip that black hole entropy can be derived from a central charge of the Virasoro algebra arising as a subalgebra in the surface deformations of General Relativity in any dimension. Here it is shown that the argumentation given in Section 2 of hep-th/9812013 and based on the Regge-Teitelboim approach is unsatisfactory. The functionals used are really ``non-differentiable'' under required variations and also the standard Poisson brackets for these functionals are exactly zero so being unable to get any Virasoro algebra with a central charge. Nevertheless Carlip's calculations will be correct if we admit another definition for the Poisson bracket. This new Poisson bracket differs from the standard one in surface terms only and allows to work with ``non-differentiable'' functionals.

description: The flow taking place in the rear part of the fuselage during the emergency landing on water is investigated experimentally in realistic conditions. To this aim, tests on a double curvature specimen have been performed at horizontal velocities ranging from 21 m/s to 45 m/s. Tests data highlight different cavitation and/or ventilation modalities which are highly dependent on the horizontal velocity, with substantial variations in the flow features occurring with velocity variations of few meters per second. For the specimen considered here, the inception of the cavitation is found at about 30 m/s, confirming that scaled model tests performed at small horizontal velocities are unable to capture the hydrodynamics correctly. By comparing pressure data, underwater movies and force measurements, it is shown that the transition from cavitation to ventilation condition has a significant effect of the longitudinal distribution of the loading which, together with inertia, aerodynamic loads and engine thrust, governs the aircraft dynamics.

description: We consider smooth electrovac spacetimes which represent either (A) an asymptotically flat, stationary black hole or (B) a cosmological spacetime with a compact Cauchy horizon ruled by closed null geodesics. The black hole event horizon or, respectively, the compact Cauchy horizon of these spacetimes is assumed to be a smooth null hypersurface which is non-degenerate in the sense that its null geodesic generators are geodesically incomplete in one direction. In both cases, it is shown that there exists a Killing vector field in a one-sided neighborhood of the horizon which is normal to the horizon. We thereby generalize theorems of Hawking (for case (A)) and Isenberg and Moncrief (for case (B)) to the non-analytic case.

Kantian Love and the Problem of Love's Object
Creators: name: Bittick, Jackson
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: The Kantian view of love says our rational nature, understood as the “proper self,” not only makes us worthy of respect, but also fitting for love. But this raises the problem of love’s object: I might be worthy of love as a rational being, but what is it to love me, a concrete individual? I argue the Kantian view should appeal to the person’s qualities to bridge the gap between the attitude of love and the object of love. When we understand the proper self as a valuing being, we see that a person’s qualities are directly connected to, and expressive of, what they value. When we love somebody for their style of humor, their style of intellect, etc., we love them for the way that they are expressing their personhood, and thus loving them for who they are.

description: We examine the dynamics of silica particles grafted with high molecular weight polystyrene suspended in semidilute solutions of chemically similar linear polymer using x-ray photon correlation spectroscopy. The particle dynamics decouple from the bulk viscosity despite their large hydrodynamic size and instead experience an effective viscosity that depends on the molecular weight of the free polymer chains. Unlike for hard sphere nanoparticles in semidilute polymer solutions, the diffusivities of the polymer-grafted nanoparticles do not collapse onto a master curve as a function of normalized length scales. These results suggest that the soft interaction potential between polymer-grafted nanoparticles and free polymer allows polymer-grafted nanoparticles to diffuse faster than predicted based on bulk rheology and modifies the coupling between grafted particle dynamics and the relaxations of the surrounding free polymer.

description: We present new analytic and numerical results for self-gravitating SU(2)-Higgs magnetic monopoles approaching the black hole threshold. Our investigation extends to large Higgs self-coupling, lambda, a regime heretofore unexplored. When lambda is small, the critical solution where a horizon first appears is extremal Reissner-Nordstrom outside the horizon but has a nonsingular interior. When lambda is large, the critical solution is an extremal black hole with non-Abelian hair and a mass less than the extremal Reissner-Nordstrom value. The transition between these two regimes is reminiscent of a first-order phase transition. We analyze in detail the approach to these critical solutions as the Higgs expectation value is varied, and compare this analysis with the numerical results.

description: Experiments were performed with Fabry-Perot optical resonators in vacuum at low temperatures. Mirrors were applied on substrates of various optical materials. The infrared laser with a wavelength of 1.064 microns was used. The pump power at the maximum could reach 450 mW. The evolution of the optical properties of the FP cavity was traced in the temperature range (300 - 10)K. The main parameters measured were the integral characteristics of the FP resonances: sharpness (finesse) and contrast of interference. Three types of substrates were tested: a sitall -- the optical glass with ultra low thermal expansion (ULE), sapphire and calcium fluoride. During cooling, the degradation of the integral characteristics of the FP cavity was observed for the sitall mirrors due to the loss of the properties of (ULE), for sapphire mirrors due to the birefringence effect. The satisfactory constancy of the integral characteristics of the FP resonator on calcium fluoride was demonstrated in the entire temperature range studied 1

description: Tracer diffusion and hydrodynamic dispersion in two-dimensional fractures with self-affine roughness is studied by analytic and numerical methods. Numerical simulations were performed via the lattice-Boltzmann approach, using a new boundary condition for tracer particles that improves the accuracy of the method. The reduction in the diffusive transport, due to the fractal geometry of the fracture surfaces, is analyzed for different fracture apertures. In the limit of small aperture fluctuations we derive the correction to the diffusive coefficient in terms of the tortuosity, which accounts for the irregular geometry of the fractures. Dispersion is studied when the two fracture surfaces are simple displaced normally to the mean fracture plane, and when there is a lateral shift as well. Numerical results are analyzed using the $Λ$-parameter, related to convective transport within the fracture, and simple arguments based on lubrication approximation. At very low Péclet number, in the case where fracture surfaces are laterally shifted, we show using several different methods that convective transport reduces dispersion.

description: In the context of quintessence, the concept of tracking solutions allows to address the fine-tuning and coincidence problems. When the field is on tracks today, one has $Q\approx m_{\rm Pl}$ demonstrating that, generically, any realistic model of quintessence must be based on supergravity. We construct the most simple model for which the scalar potential is positive. The scalar potential deduced from the supergravity model has the form $V(Q)=\frac{Λ^{4+α}}{Q^α}e^{\fracκ{2}Q^2}$. We show that despite the appearence of positive powers of the field, the coincidence problem is still solved. If $α\ge 11$, the fine-tuning problem can be overcome. Moreover, due to the presence of the exponential term, the value of the equation of state, $ω_Q$, is pushed towards the value -1 in contrast to the usual case for which it is difficult to go beyond $ω_Q\approx -0.7$. For $Ω_{\rm m}\approx 0.3$, the model presented here predicts $ω_Q\approx -0.82$. Finally, we establish the $Ω_{\rm m}-ω_Q$ relation for this model.

CRITICAL CARE COMPETENCY ENHANCEMENT: STRATEGIES FOR EFFECTIVE RESPONSE DURING GLOBAL HEALTH EMERGENCIES

description: The COVID-19 pandemic has magnified the global healthcare workforce crisis, with an alarming shortage of nurses. Adequate nurse staffing is essential for a safe and healthy clinical environment. However, as the pandemic swept across the world, it exacerbated the existing staffing issues, particularly affecting nurses. The World Health Organization (WHO) declared COVID-19 a global pandemic in January 2020, leading to millions of infections and a surge in patient admissions. Nurses, who play a vital role in healthcare delivery across various settings, including acute care facilities and long-term care services, found themselves under immense pressure.

The WHO's State of the World's Nursing report revealed a global shortage of 5.9 million nurses, further aggravated by the strain imposed by the pandemic on global healthcare systems. Disturbingly, the International Council of Nurses (ICN) predicts a shortage of over 10 million nurses by 2030 if no interventions are made. This shortage results from various factors, including clinical exposures, nurse sickness, burnout, and the need to attend to family members at home. This paper sheds light on the critical nurse staffing issue that has gained prominence due to the pandemic and emphasizes the urgency of addressing this crisis to ensure quality patient care
Relational Morality and the Problem of the Participant Stance

description: Something has gone morally amiss when someone tries to engage another person as a fellow, and the other refuses to engage with or even acknowledge them. In this essay, I suggest we should understand what’s gone morally amiss in such cases in terms of a claim we have on others that they acknowledge us as moral peers. I argue that two prominent moral theories that focus on the significance of interpersonal recognition and the role of claims in morality– Darwall’s theory in The Second Person Standpoint and Wallace’s theory in The Moral Nexus– surprisingly cannot accommodate a claim that others afford us that interpersonal recognition. I conclude by speculating about why Darwall and Wallace’s views share this lacuna.

description: In this paper we discuss the connection between the geometric and tetrad approaches in the quantum affine-metric gravity. The corresponding transition formulas are obtained at the one-loop level. As an example, the one-loop counterterms are calculated in the tetrad formalism in the theory with terms quadratic in the torsion field. This model possesses the extra local symmetries connected with transformation of the connection field. It is shown that the special gauge can be chosen so that the corresponding additional ghosts do not contribute to the one-loop divergent terms.

Probability models of chance fluctuations in spectra of astronomical sources with applications to X-ray absorption lines

Publisher: name: arXiv
Year: 2018
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: The search for faint emission or absorption lines in astronomical spectra has received considerable attention in recent years, especially in the X-ray wavelength range. These features usually appear as a deficit or excess of counts in a single resolution element of the detector, and as such they are referred to as unresolved fluctuations. The general problem under investigation is the probability of occurrence of chance fluctuations. A quantitative answer is necessary to determine whether detected fluctuations are a real (astronomical, in this case) signal, or if they can be attributed to chance. This application note provides a new comprehensive method to answer this question as function of the instrument's resolution, the wavelength coverage of the spectrum, the number of fluctuations of interest, and the confidence level chosen. The method is based on the binomial distribution, and addresses also the probability of multiple simultaneous fluctuations. A critical aspect of the model is the a priori knowledge of the location of possible fluctuations, which significantly affects the probability of detection. In fact, a wider wavelength range for the 'blind' search of possible fluctuations results in a larger number of 'tries' for the detection of a fluctuation, lowering the overall significance of a specific feature. The method is illustrated with a case study and examples using X-ray data.

description: We show that surgery on a connected clover (or clasper) with at least one loop preserves the concordance class of a knot. Surgery on a slightly more special class of clovers preserves invertible concordance. We also show that the converse is false. Similar results hold for clovers with at least two loops vs. S-equivalence.

description: In this paper Nowak--Szamrej-Latané model is reconsidered. This computerised model of opinion formation bases on Latané theory of social impact. We modify this model to allow for multi (more than two) opinions. With computer simulations we show that in the modified model the signatures of order/disorder phase transition are still observed. The transition may be observed in the average fraction of actors sharing the $i$-th opinion, its variation and also average number of clusters of actors with the same opinion and the average size of the largest cluster of actors sharing the same opinion. Also an influence of model control parameters on simulation results is shortly reviewed. For a homogeneous society with identical actors' supportiveness and persuasiveness the critical social temperature $T_C$ decreases with an increase of available opinions $K$ from $T_C=6.1$ ($K=2$) via 4.7, 4.1 to $T_C=3.6$ for $K=3$, 4, 5, respectively.

description: Abstract:  The principal aim of this paper is to analyse the urban form, the buildings, and the system of open spaces of a city in Spain, Morella, in the present, looking back to understand the meaning of things, and to show, using examples, that history, as context or precedent, over different periods of time, has always been a design tool. History allowed architects to find a balance between permanence and change in changing a place and offering users a ‘new’ place in which memories and hope can converge. To explain the transparency between architectural design and history, the city was analysed through drawings, historical paintings, ethnographic reports, and in current and ancient maps. The result is a longitudinal study of Morella that brings together: morphological configuration studies, the poetic act of design and, finally, the social use of space. The text shows how architects, as historians who read the built environment, and history, as a source material for architectural practice, make the dialogic relationship between contemporary design and the history of the place transparent.
The Night Unraveled: Nocturnal Significances in Seventeenth-Century French Court Ballets
Creators: name: Sammartano, Matteo
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: This thesis delves into the multilayered significance of nocturnal themes in seventeenth-century French court ballets. While the night served as a potent vehicle for conveying political messages within a spectacular framework, its substance extended beyond the sole realm of political allegory. By amalgamating music, dance, poetry, and political undertones, the court ballet emerges as a privileged lens through which to unravel the night’s significances and to interrogate the implications of its spectacularization in the French seventeenth century. The examination of selected nocturnal ballets and seventeenth-century theories sheds light on the night’s ability to intersect with discourses on the harmony of the cosmos, the baroque inclination for the marvelous and the artifice, and the expression of royal authority. Specifically, this thesis discusses how the night confounds universal order, temporal delineation, and fantastical imagination in court spectacle, while highlighting the royal impetus to discipline the night’s porous nature.
Rotating Hele-Shaw cells with ferrofluids

description: We investigate the flow of two immiscible, viscous fluids in a rotating Hele-Shaw cell, when one of the fluids is a ferrofluid and an external magnetic field is applied. The interplay between centrifugal and magnetic forces in determining the instability of the fluid-fluid interface is analyzed. The linear stability analysis of the problem shows that a non-uniform, azimuthal magnetic field, applied tangential to the cell, tends to stabilize the interface. We verify that maximum growth rate selection of initial patterns is influenced by the applied field, which tends to decrease the number of interface ripples. We contrast these results with the situation in which a uniform magnetic field is applied normally to the plane defined by the rotating Hele-Shaw cell.

description: We report angle-resolved photoemission spectra both above and below T_c in the single-plane cuprate superconductor Bi_2Sr_{2-x}La_xCuO_{6+d}. The superconducting state measurements show a highly anisotropic excitation gap with a maximum magnitude smaller than that of the bilayer compound Bi_2Sr_2CaCu_2O_8 by a factor of 3. For a range of doping, the gap persists well above T_c, behavior previously associated with underdoped bilayer cuprates. The anisotropy and magnitude of the normal-state gap are very similar to the superconducting state gap, indicating that the two gaps may have a common origin in a pairing interaction.

description: Abstract

Access to skilled birth attendants is a critical factor in reducing maternal and neonatal mortality rates. This study examines the determinants of access to skilled birth attendants among women in Hamar Ja-jab District, Mogadishu, Somalia. The research investigates the socio-demographic, economic, and cultural factors influencing the utilization of skilled delivery services.

Using a cross-sectional study design, data was collected through surveys and interviews with pregnant women, healthcare providers, and community members. The findings reveal that low maternal education levels, financial constraints, cultural beliefs favoring traditional birth attendants, and inadequate healthcare infrastructure significantly hinder access to skilled birth attendants. Additionally, a lack of awareness about the benefits of skilled care and transportation challenges further contribute to low utilization rates.

The study underscores the urgent need for policy interventions to enhance access to skilled birth attendants. Recommendations include strengthening maternal health education programs, improving healthcare facilities, increasing financial support for maternal care, and raising awareness about the risks associated with unskilled delivery. These findings provide valuable insights for policymakers, healthcare providers, and organizations striving to improve maternal health outcomes in Somalia.
"To Rend the Union into Fragments:" The 1860 Association, Propaganda, and the Secession Crisis
Creators: name: Roth , Claire
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: This thesis explores the actions and impact of the Charleston-based secessionist propaganda machine known as the 1860 Association. A handful of elite South Carolina slaveholders organized in the months leading up to the election of 1860 and operated, as the 1860 Association, with the goal of persuading fellow white Southerners to support immediate state secession. This thesis seeks to uncover not only the rhetorical and propaganda strategies employed by the 1860 Association, but also the impact of their campaign on the broader secession movement. I argue that by relying on the tenets of proslavery ideology and subverting class tension in favor of white racial unity, the 1860 Association persuasively presented secession as both the South’s only remaining path forward and as a rational and defensive action. This thesis demonstrates that the 1860 Association’s propaganda campaign was prolific, strategic, and had a clear impact on the secession movement across the South.

description: The theory of distributions in non-Riemannian spaces is used to obtain exact static thin domain wall solutions of Einstein-Cartan equations of gravity. Curvature $ δ$-singularities are found while Cartan torsion is given by Heaviside functions. Weitzenböck planar walls are caracterized by torsion $δ$-singularities and zero curvature. It is shown that Weitzenböck static thin domain walls do not exist exactly as in general relativity. The global structure of Weitzenböck nonstatic torsion walls is investigated.

Infinitely Generated virtually free pro-$p$ groups and $p$-adic representations

description: We prove the pro-$p$ version of the Karras, Pietrowski, Solitar, Cohen and Scott result stating that a virtually free group acts on a tree with finite vertex stabilizers. If a virtually free pro-$p$ group $G$ has finite centralizes of all non-trivial torsion elements more stronger statement is proved: $G$ embeds into a free pro-$p$ product of a free pro-$p$ group and finite $p$-group. The integral $p$-adic representation theory is used in the proof; it replaces the Stallings theory of ends in the pro-$p$ case.

description: According to the positive energy conjecture of Horowitz and Myers, there is a specific supergravity solution, AdS soliton, which has minimum energy among all asymptotically locally AdS solutions with the same boundary conditions. Related to the issue of semiclassical stability of AdS soliton in the context of pure gravity with a negative cosmological constant, physical boundary conditions are determined for an instanton solution which would be responsible for vacuum decay by barrier penetration. Certain geometric properties of instantons are studied, using Hermitian differential operators. On a $d$-dimensional instanton, it is shown that there are $d-2$ harmonic functions. A class of instanton solutions, obeying more restrictive boundary conditions, is proved to have $d-1$ Killing vectors which also commute. All but one of the Killing vectors are duals of harmonic one-forms, which are gradients of harmonic functions, and do not have any fixed points.

description: In the realm of critical care nursing, effective management of patients requiring ventilator support is a multifaceted challenge. This study explores the complexities faced by critical care nurses in Sudan, where the demand for mechanical ventilation has surged due to increased chronic illness cases and a growing focus on reducing external healthcare costs. Ventilator support entails addressing various physiological conditions, including those that impede optimal ventilator functionality, and attending to issues such as dyspnea and patient-ventilator dyssynchrony.

During the mechanical ventilation process, patients exhibit diverse responses, necessitating careful monitoring and adjustments to achieve therapeutic goals like enhanced oxygenation, improved ventilation, heightened patient comfort, and the prevention of secondary injuries. While certain technical aspects of ventilator management fall within the purview of respiratory care practitioners, nurses play a crucial role in ensuring holistic patient care. They address common symptoms and responses related to mechanical ventilator support. This study aims to enhance the knowledge and practices of nursing staff concerning endotracheal tube and tracheostomy care
