description: We study fully localized BPS brane solutions in classical supergravity using a perturbative approach to the coupled Born-Infeld/bulk supergravity system. We derive first order bulk supergravity fields for world-volume solitons corresponding to intersecting M2-branes and to a fundamental string ending on a D3-brane. One interesting feature is the appearance of certain off-diagonal metric components and corresponding components of the gauge potentials. Making use of a supersymmetric ansatz for the exact fields, we formulate a perturbative expansion which applies to $M2 \perp M2 (0), M5 \perp M5 (3)$ and $Dp \perp Dp (p-2)$ intersections. We find that perturbation theory qualitatively distinguishes between certain of these cases: perturbation theory breaks down at second order for intersecting M2-branes and D$p$-branes with $p\le 3$ while it is well behaved, at least to this order, for the remaining cases. This indicates that the behavior of the full non-linear intersecting Dp-brane solutions may be qualitatively different for $p \le 3$ than for $p \ge 4$, and that fully localized asymptotically flat solutions for $p \le 3$ may not exist. We discuss the consistency of these results with world-volume field theory properties.

description: The diffuse and translucent molecular clouds traced in absorption along the line of sight to strong background sources have so far been investigated mainly in the spectral domain because of limited angular resolution or small sizes of the background sources. We aim to resolve and investigate the spatial structure of molecular clouds traced by several molecules detected in absorption along the line of sight to SgrB2(N). We have used spectral line data from the EMoCA survey performed with ALMA, taking advantage of the high sensitivity and angular resolution. We identify, on the basis of the spectral analysis of c-C3H2 across the field of view, 15 main velocity components along the line of sight to SgrB2(N) and several components in the envelope of SgrB2. The c-C3H2 column densities reveal two categories of clouds. Clouds in Category I (3 kpc arm, 4 kpc arm, and some GC clouds) have smaller c-C3H2 column densities, smaller linewidths, and smaller widths of their column density PDFs than clouds in Category II (Scutum arm, Sgr arm, and other GC clouds). To investigate the spatial structure we derive opacity maps for the following molecules: c-C3H2, H13CO+, 13CO, HNC, HN13C, HC15N, CS, C34S, 13CS, SiO, SO, and CH3OH. These maps reveal that most molecules trace relatively homogeneous structures that are more extended than the field of view defined by the background continuum emission (about 15", that is 0.08-0.6pc depending on the distance). SO and SiO show more complex structures with smaller clumps of size ~5-8". Our analysis suggests that the driving of the turbulence is mainly solenoidal in the investigated clouds. On the basis of HCO+, we conclude that most line-of-sight clouds towards SgrB2 are translucent, including all clouds where complex organic molecules were recently detected. We also conclude that CCH and CH are good probes of H2 in both diffuse and translucent clouds.

Body Optics, the Theory of Seeing the Self: Dogu, Bodies, and the Art History Canon in Prehistoric Japan
Creators: name: Hack, Sylvie Esheborg
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: This thesis discusses the Jomon period dogū and places them within the greater art historical canon. Using LeRoy McDermott’s theory of self-representation and Body Optics, the Theory of Seeing the Self, I argue that dogū are representations of the artists who created them. First, I argue that the Chobonaino Dogu and the Standing Dogū from Nishinomae are representations of deities due to their fluid nature and the lack of body foreshortening. Secondly, I argue that masked dogū with anatomically correct yonic genitalia are representations of Jōmon shamans due to their connection with female bodies and the spiritual realm. Lastly, I propose a cross-cultural visual analysis between the Jōmon Venus and the Woman of Willendorf and offer a critique of the current art history canon with a proposal to make it more inclusive.

description: We study the covariant free bosonic string field theory and explore its locality (causality) properties. We find covariant string fields which are strictly local and covariant, but act on an unconstrained Hilbert space with an indefinite inner product. From these we also define observable fields which act on the physical Hilbert space with an definite inner product. These are shown to be approximately local.
Walking With Our Ghosts: Visions of Utopia and Crisis in the South Carolina Lowcountry
Creators: name: George, Spencer
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: In 2021, a ProPublica study on climate migration ranked Beaufort County, South Carolina #1 out of 3,143 total American counties as the county facing the greatest threat of compounded climate factors. In conjunction with research on the neighboring counties of Colleton and Charleston, South Carolina, this thesis examines the past, present, and future implications of this data and how it is being processed by artists working in and around the Lowcountry coast. In spaces facing precarity and displacement—both economic and environmental—artists are envisioning alternate ecological imaginaries that counter historical visions of the South as a nostalgic utopia rooted in tradition and beauty. These visions offer a pathway forward that sits with the ghosts of past and present, bearing witness to a burgeoning climate crisis, the breakdown of regional and national identity, and long-unresolved histories of violence, exploitation, and othering. In using creative practice to envision these alternate futures, Lowcountry artists embody what this work proposes as the role of the “folk-futurist,” a new turn in the field of folklore that asks cultural practitioners to work alongside communities to imagine themselves from a future perspective in order to re-imagine the present moment as one that can be shifted and influenced through creative action. By weaving together methodologies from folklore and the arts to approach environmental change, this work crafts a new vision for the Lowcountry, one grounded in the uncovering of ghosts that can teach us as much about the future as they can about the past.

description: In this work, we have successfully developed novel silver nanoconjugates of pyrazolone analogue and screened its chemosensing potential in aqueous medium. Bispyrazolone silver nanoparticles (Bispyra-AgNPs) were synthesised and characterised through FTIR, UV-visible spectroscopy and atomic force microscopy. The sensing ability was explored towards Ca2+, Cd2+, Co2+, Cu2+, Fe2+, Li+, Pb2+, La3+, Hg2+, Mg2+, Ni2+ and Ba2+ metal ions, respectively. Bispyra-AgNPs showed a highly quenching potential in selective recognition of Cu2+and colour of the solution immediately turned from yellow to purple, after the addition of Cu2+ in to the solution. The developed method also displayed a remarkable selectivity for Cu2+ over others interfering metal ions. The binding ratio and stoichiometry of host-guest complex was found to be 1:1 and determined by Job’s method. The propose method is facile and sensitive to detect Cu2+ with detection limit of 10 µM.

description: Abstract: Internationally associated with the Rio de Janeiro scene, favelas are typical features of the urban landscape in all main Brazilian cities, primarily in metropolitan areas. Favelas are the places where the poor are forced to gather to continue living in urban areas, in a process that increasingly pushes them towards the outskirts of the cities. Considering the São Paulo metropolis, the Paraisópolis favela has been mostly shaped by the dwellers’ individual actions, who built it and shaped it to what we see today. The buildings erected by public authorities on the borders of the community represent the main formal breach of continuity. Considering this formal discrepancy and the apparent homogeneity of the urban fabric in Paraisópolis, this article seeks to understand the complexity of the urban form in this favela, working in the theoretical field of urban morphology as presented by Costa and Netto (2014) and Oliveira (2016), as well as in the procedure developed by geographer Conzen (1960), who is considered the creator of the British School of urban morphology. Through the analysis proposed in this study, it has been realized that changes in urban form are consistent with the socioeconomic periods which overlap in today’s city. We have noticed a correlation between the Paraisópolis study, and a study carried out by Conzen (1960) in the city of Alnwick, in England. The database consisted of cartography and aerial photographs found in public planning agencies. These data were redrawn and georeferenced. Understanding favelas through morphological studies is no novelty; however, the accomplishment of this work has been to remain within the array of the most solid research studies.

description: In this article, we study a class of problems where the sum of truncated convex functions is minimized. In statistical applications, they are commonly encountered when ℓ0-penalized models are fitted and usually lead to NP-Hard non-convex optimization problems. In this article, we propose a general algorithm for the global minimizer in low-dimensional settings. We also extend the algorithm to high-dimensional settings, where an approximate solution can be found efficiently. We introduce several applications where the sum of truncated convex functions is used, compare our proposed algorithm with other existing algorithms in simulation studies, and show its utility in edge-preserving image restoration on real data.

description: Excerpts from the report: In 1935, 354,000 grocery stores sold $7.8 billion of food. In 1958, 285,000 grocery stores sold $44.1 billion of food. The number of stores had declined 20 percent and average sales per store had increased nearly sixfold. The supermarket had taken over most of food retailing. This study briefly describes some of the changes which have taken place in the structure of food retailing--characterized by the rise of the supermarket--and analyzes and evaluates the effects on the fresh fruit and vegetable industry. The policies and practices of chain supermarket organizations in promoting and selling fresh fruits and vegetables, the effects of these policies on procurement methods, and their impacts on production and marketing methods are described and analyzed. The goal of this study is to assist producers and marketers of fresh fruits and vegetables to understand better the marketing system with which they are dealing. The marketing system is constantly changing, and in recent years both the direction and rate of change have shifted. An awareness of these developments is essential in order for producers and marketers to be able to plan for the future in the most productive manner.

description: Thanks to the organizers of the 3rd Annual Chemical Biology in the Hub event I was given an opportunity to open the meeting. To get us started, I thought it would be valuable to enlist the help of an auditorium full of chemical biologists to brainstorming about where we wanted our field to go next and what we wanted chemical biology to be. Why is this an important conversation to have at this point? In my view, chemical biology is still a youngish field. We have reached a stage of adolescence when we can do a great many things, we are energetic, we are excited, we continue to test the limits and we are definitely ready to dive into things that others may view as intellectually potentially dangerous! Our field is growing, thanks to many early career scientists who have been joining us. With this comes a growing responsibility to create a community that welcomes others and ensures their mentoring and wellbeing. Additionally, we have to be ready to be vocal and advocate for what it is that chemical biology can do and why it matters, and what our culture and standards are. And that’s why I decided to put this question of what it is that we want to be when we grow up in front of everyone in the audience at the Third Annual "Chemical Biology in the HUB" symposium.
Securing quantum networking tasks with multipartite Einstein-Podolsky-Rosen steering

description: Einstein-Podolsky-Rosen (EPR) steering is the explicit demonstration of the fact that the measurements of one party can in influence the quantum state held by another, distant, party, and do so even if the measurements themselves are untrusted. This has been shown to allow one-sided device-independent quantum-information tasks between two remote parties. However, in general, advanced multiparty protocols for generic quantum technologies, such as quantum secret sharing and blind quantum computing for quantum networks, demand multipartite quantum correlations of graph states shared between more than two parties. Here, we show that, when one part of a quantum multidimensional system composed of a two-colorable graph state (e.g., cluster and Greenberger-Horne-Zeilinger states) is attacked by an eavesdropper using a universal cloning machine, only one of the copy subsystems can exhibit multipartite EPR steering but not both. Such a no-sharing restriction secures both state sources and channels against cloning-based attacks for generic quantum networking tasks, such as distributed quantum-information processing, in the presence of uncharacterized measurement apparatuses.

description: With increasing interest and availability of Object-Centric Event Data (OCED), the focus of process mining research is shifting towards object-centric techniques. OCED removes the requirement of a single case notion, i.e., that all events only belong to exactly once case. Thus, OCED can capture real-life processes much more accurately. In this thesis, we introduce a declarative querying and constraint approach for OCED, focusing specifically on very high expressiveness while still allowing for efficient execution in practice. We first present and formalize a way to formulate nested queries of combinations of objects and events, so-called variable bindings. In contrast to prior work, our approach allows for querying combinations of multiple objects and events of any types. For example, also permitting queries for two orders placed by the same customer, one placed after the other. Constraints are presented as an extension to the querying approach, additionally specifying for each queried binding if it should be considered satisfied or violated. We introduce a visual notation for the queries and constraints of our approach and present a supporting tool implementation. Apart from the approach formalization, we also describe how the proposed types of declarative queries and constraints can be efficiently algorithmically evaluated on input OCED. Additionally, we outline how some types of constraints, which are very relevant for real-life processes, can be discovered automatically based on input OCED. Finally, we also evaluate the presented query and constraint approach by showcasing example constraints, demonstrating the high expressiveness and convenient visual representation of simple and complex constraints. Moreover, we explore the scalability and runtime performance of our approach implementation, showing excellent performance even for large real-life datasets with more than one million events.

description: We calculate the electronic structure of nm scale InP islands embedded in $Ga_{0.51}In_{0.49}P$. The calculations are done in the envelope approximation and include the effects of strain, piezoelectric polarization, and mixing among 6 valence bands. The electrons are confined within the entire island, while the holes are confined to strain induced pockets. One pocket forms a ring at the bottom of the island near the substrate interface, while the other is above the island in the GaInP. The two sets of hole states are decoupled. Polarization dependent dipole matrix elements are calculated for both types of hole states.

description: CeMnNi$_4$ exhibits an unusually large spin polarization, but its origin has baffled researchers for more than a decade. We use bulk sensitive hard x-ray photoelectron spectroscopy (HAXPES) and density functional theory based on the Green's function technique to demonstrate the importance of electron-electron correlations of both the Ni 3$d$ ($U_{Ni}$) and Mn 3$d$ ($U_{Mn}$) electrons in explaining the valence band of this multiply correlated material. We show that Mn-Ni anti-site disorder as well as $U_{Ni}$ play crucial role in enhancing its spin polarization: anti-site disorder broadens a Ni 3$d$ minority-spin peak close to the Fermi level ($E_F$), while an increase in $U_{Ni}$ shifts it towards $E_F$, both leading to a significant increase of minority-spin states at $E_F$. Furthermore, rare occurrence of a valence state transition between the bulk and the surface is demonstrated highlighting the importance of HAXPES in resolving the electronic structure of materials unhindered by surface effects.

description: We study a dissipative Kerr-resonator subject to both single- and two-photon detuned drives. Beyond a critical detuning threshold, the Kerr resonator exhibits a semiclassical first-order dissipative phase transition between two different steady-states, that are characterized by a $π$ phase switch of the cavity field. This transition is shown to persist deep into the quantum limit of low photon numbers. Remarkably, the detuning frequency at which this transition occurs depends almost-linearly on the amplitude of the single-photon drive. Based on this phase switching feature, we devise a sensitive quantum transducer that translates the observed frequency of the parametric quantum phase transition to the detected single-photon amplitude signal. The effects of noise and temperature on the corresponding sensing protocol are addressed and a realistic circuit-QED implementation is discussed.

description: The strong CP problem is a compelling motivation for physics beyond the Standard Model. The most popular solutions invoke a global Peccei-Quinn symmetry, but are challenged by quantum gravitational corrections which are thought to be incompatible with global symmetries, arguing that realistic theories contain additional structure. We explore a construction in which the Peccei-Quinn symmetry is protected to arbitrary order by virtue of a supersymmetric, confining $SU(N)_L \times SU(N) \times SU(N)_R \times U(1)_X$ product gauge group, achieving $\barθ< 10^{-11}$ for an $SU(5)$ model with $f_a \lesssim 3 \times 10^{11}$ GeV. This construction leads to low energy predictions such as a $U(1)_X$ gauge symmetry, and for $X = B-L$ engineers a naturally order ~TeV value for the $μ$ parameter of the MSSM.

description: We study the near horizon limit of a four dimensional extreme rotating black hole. The limiting metric is a completely nonsingular vacuum solution, with an enhanced symmetry group SL(2,R) x U(1). We show that many of the properties of this solution are similar to the AdS_2 x S^2 geometry arising in the near horizon limit of extreme charged black holes. In particular, the boundary at infinity is a timelike surface. This suggests the possibility of a dual quantum mechanical description. A five dimensional generalization is also discussed.

Forward particle production in proton-nucleus collisions at next-to-leading order

description: We consider the next-to-leading order (NLO) calculation of single inclusive particle production at forward rapidities in proton-nucleus collisions and in the framework of the Color Glass Condensate (CGC). We focus on the quark channel and the corrections associated with the impact factor. In the first step of the evolution the kinematics of the emitted gluon is kept exactly (and not in the eikonal approximation), but such a treatment which includes NLO corrections is not explicitly separated from the high energy evolution. Thus, in this newly established "factorization scheme", there is no "rapidity subtraction". The latter suffers from fine tuning issues and eventually leads to an unphysical (negative) cross section. On the contrary, our reorganization of the perturbation theory leads by definition to a well-defined cross section and the numerical evaluation of the NLO correction is shown to have the correct size.

description: The photodynamic properties of molecules determine their ability to survive in harsh radiation environments. As such, the photostability of heterocyclic aromatic compounds to electromagnetic radiation is expected to have been one of the selection pressures influencing the prebiotic chemistry on early Earth. In the present study, the gas-phase photodynamics of uracil, 5-methyluracil (thymine) and 2-thiouracil -- three heterocyclic compounds thought to be present during this era -- are assessed in the context of their recently proposed intersystem crossing pathways that compete with internal conversion to the ground state. Specifically, time-resolved photoelectron spectroscopy measurements evidence femtosecond to picosecond timescales for relaxation of the singlet 1$ππ$* and 1n$π$* states as well as for intersystem crossing to the triplet manifold. Trapping in the excited triplet state and intersystem crossing back to the ground state are investigated as potential factors contributing to the susceptibility of these molecules to ultraviolet photodamage.

description: This thesis describes the design and synthesis of novel fluorescent and non-fluorescent derivatives of the cyclic peptide GR231118 and the study of their actions at the Y1 and the Y4 receptors. A refined understanding of the molecular mechanism of peptide binding to the receptors was obtained. The effect of GR231118 treatment on receptor organisation at the cell membrane was also investigated. Results indicate that treatment with the dimer GR231118 peptide leads to Y1 receptor clustering. Collectively, the thesis improves understanding of the Y1 and Y4 receptor pharmacology which will lead the development of new therapeutic approaches in several diseases.

description: We have developed low-dispersion (1480 l/mm), resonance-free, diffraction gratings made of dielectric materials resistant to femtosecond laser damage $(SiO_{2}/HfO_{2})$. A 14 cm diameter sample was fabricated resulting in a mean diffraction efficiency of 99.1% at λ = 810 nm with 0.4% uniformity using equipment which can fabricate gratings up to 1m diagonal. The implementation of these gratings in the compression of 30 fs pulses in an out-of-plane geometry can result in compressor efficiencies of ~95%. The measured laser absorption is 500x lower than current ultrafast petawatt-class compressor gratings which will enable a substantial increase in average power handling capabilities of these laser systems.

description: This project examines repatriation and funerals for American servicemembers who died in Cuba, starting with the explosion of the U.S.S. Maine in February 1898 through the Battle of San Juan Hill in July 1898. As these deaths occurred before the July 1898 War Department policy establishing government-funded repatriation, it focuses on the range of efforts of bereaved families, the American and Spanish colonial governments, the military, and the media as they all sought ad hoc solutions to the novel circumstances of overseas American wartime death. As these groups interacted with one another to construct and perform repatriation ceremonies, funerals, and enduring commemorative efforts—a process that I refer to collectively as “military rites of burial”—they established new norms for the treatment of America’s war dead, created spectacles that reflected the nation’s response to wartime death, and laid the foundation of the conflict’s collective memory.

The Anderson-Josephson quantum dot -- A theory perspective

Publisher: name: arXiv

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: Recent progress in nanoscale manufacturing allowed to experimentally investigate quantum dots coupled to two superconducting leads in controlled and tunable setups. The equilibrium Josephson current was measured in on-chip SQUID devices and subgap states were investigated using weakly coupled metallic leads for spectroscopy. This put back two "classic" problems also on the agenda of theoretical condensed matter physics: the Josephson effect and quantum spins in superconductors. We discuss the status of the theoretical understanding of the Anderson-Josephson quantum dot in equilibrium mainly focusing on the Josephson current. We introduce a minimal model consisting of a dot which can only host one spin-up and one spin-down electron repelling each other by a local Coulomb interaction. The dot is tunnel-coupled to two superconducting leads described by the BCS Hamiltonian. This model was investigated using a variety of methods, some capturing aspects of Kondo physics others failing in this respect. We briefly review this. The model shows a first order level-crossing quantum phase transition when varying any parameter provided the others are within appropriate ranges. At vanishing temperature it leads to a jump of the Josephson current. We show that a quantitative agreement between accurate results obtained for the simple model and measurements of the current can be reached. This confirms that the experiments reveal the finite temperature signatures of the zero temperature transition. In addition, we consider two examples of more complex dot geometries which might be experimentally realized in the near future. The first is characterized by the interplay of the above level-crossing physics and the Fano effect, the second by the interplay of superconductivity and almost degenerate singlet and triplet two-body states.

description: We predict the existence of a new type of spatiotemporal solitons ("light bullets") in two-dimensional self-induced-transparency media with refractive index modulation in the direction transverse to that of pulse propagation. These self-localized guided modes are found in an approximate analytical form, their existence and stability being confirmed by numerical simulations, and may have advantageous properties for signal transmission.

description: Abstract 

Globally, 17 million children suffer from severe acute malnutrition due to deficiency of some nutrient foods with an estimated mortality rate of 1 to 2 million in Sub-Saharan Africa. In sub-Saharan African Countries, diets of children aged under-five years are commonly based on the calorie dense foods with minimal or no animal  products and rarely do they have adequate intake of vegetables and fruits. According to horn of Africa Demographic Health Survey (2018), 44% of children under five of age in the southern region ofSomalia, dietary intake assessment was done by conducting a 24-hour dietary recall of the foods eaten by children and dietary diversity was evaluated using the WHO infant and young child feeding guidelines for that age group. Nutrient intake was determined by computing the foods consumed in terms of kilocaloriesand classifying them as adequate or inadequate. Anthropometric measurements were done on the children to determine their nutrition status. Excel version was used to manage and analyze the data, descriptive statistics were used to describe quantitative data while inferential statistics, tables and chi square was used to show associations between categorical variables; dietary diversity, intake and nutrition status and health status of children. Descriptive correlation data was used to determine the strength of association betweensocio-economic characteristics, dietary diversity and nutrition status. There was a significant relationship between socio economic status and dietary diversity score with a (p-value≤0.001). Consequently, the resultsshowed a significant relationship between dietary diversity and nutrition status Chi square (p-value≥0.002). Conclusively, the nutrition status indicated existence of under nutrition in the study area and this study recommends interventions such as nutrition education integrated with kitchen gardening for improved dietary diversity.

description: Information of material deformation upon loading is critical to evaluate mechanical properties of materials in general, and key to understand fundamental mechano-stimuli induced response of live systems in particular. Conventionally, such information is obtained at macroscopic scale about averaged properties, which misses the important details of deformation at individual structures; or at nanoscale with localized properties accessed, which misses the information of deformation at locations away from the force-loading positions. Here we demonstrate that an integration of nanodiamond orientation sensing and AFM nanoindentation offers a complementary approach to the nonlocal reconstruction of material deformation. This approach features a 5 nm precision in the loading direction and a sub-hundred nanometer lateral resolution. Using this tool, we mapped out the deformation of a PDMS thin film in air and that of the gelatin microgel particles in water, with precision high enough to disclose the significance of the surface/interface effects in the material deformation. The non-local nanometer-precision sensing of deformation upon a local impact brings in new opportunities in studying mechanical response of complex material systems.

description: Existence check of non-trivial, stationary axisymmetric black hole solutions in Brans-Dicke theory of gravity in different direction from those of Penrose, Thorne and Dykla, and Hawking is performed. Namely, working directly with the known explicit spacetime solutions in Brans-Dicke theory, it is found that non-trivial Kerr-Newman-type black hole solutions different from general relativistic solutions could occur for the generic Brans-Dicke parameter values -5/2\leq ω

description: We discuss the critical behaviour of 2D Ising and q-states Potts models coupled by their energy density. We found new tricritical points. The procedure employed is the renormalisation approach of the perturbations series around conformal field theories representing pure models as already used for disordered spins models. This analysis could be useful to understand the physics of coupled critical models like the fully frustrated XY model.

description: We review the holographic correspondence between field theories and string/M theory, focusing on the relation between compactifications of string/M theory on Anti-de Sitter spaces and conformal field theories. We review the background for this correspondence and discuss its motivations and the evidence for its correctness. We describe the main results that have been derived from the correspondence in the regime that the field theory is approximated by classical or semiclassical gravity. We focus on the case of the N=4 supersymmetric gauge theory in four dimensions, but we discuss also field theories in other dimensions, conformal and non-conformal, with or without supersymmetry, and in particular the relation to QCD. We also discuss some implications for black hole physics.

description: Methods to estimate the Hausdorff dimension of invariant sets of scattering systems are presented. Based on the levels' hierarchical structure of the time delay function, these techniques can be used in systems whose future-invariant-set codimensions are approximately equal to or greater than one. The discussion is illustrated by a numerical example of a scatterer built with four hard spheres located at the vertices of a regular tetrahedron.
