Attic Vowel Shifts: A Variationist Approach
Creators: name: Colby, Evan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: In this paper, I use evidence from Attic Greek inscriptions to draw conclusions about when two vowel mergers had become widespread among speakers of Attic Greek. I agree with Sven Tage Teodorsson's claim that there were two subdialects of Attic Greek, a more conservative and a more innovative one, but I push back against his proposal that the innovative subdialect lost ground during the Hellenistic period, suggesting instead that it was the result of a heightened interest in prescriptivism during this time period.

description: The past decade's discovery of topological excitations in nanoscale ferroelectrics has turned the prevailing view that the polar ground state in these materials is uniform. However, the systematic understanding of the topological polar structures in ferroelectrics is still on track. Here we study stable vortex-like textures of polarization in the nanocylinders of ferroelectric PbTiO3, arising due to the competition of the elastic and electrostatic interactions. Using the phase-field numerical modeling and analytical calculations, we show that the orientation of the vortex core with respect to the cylinder axis is tuned by the geometrical parameters and temperature of the system.

description: Tuning and controlling the magnetic properties of nanomaterials is crucial to implement new and reliable technologies based on magnetic hyperthermia, spintronics, or sensors, among others. Despite variations in the alloy composition as well as the realization of several post material fabrication treatments, magnetic heterostructures as ferromagnetic/antiferromagnetic coupled layers have been widely used to modify or generate unidirectional magnetic anisotropies. In this work, a pure electrochemical approach has been used to fabricate core (FM)/shell (AFM) Ni@(NiO,Ni(OH)2) nanowire arrays, avoiding thermal oxidation procedures incompatible with integrative semiconductor technologies. Besides the morphology and compositional characterization of these core/shell nanowires, their peculiar magnetic properties have been studied by temperature dependent (isothermal) hysteresis loops, thermomagnetic curves and FORC analysis, revealing the existence of two different effects derived from Ni nanowires’ surface oxidation over the magnetic performance of the array. First of all, a magnetic hardening of the nanowires along the parallel direction of the applied magnetic field with respect their long axis (easy magnetization axis) has been found. The increase in coercivity, as an effect of surface oxidation, has been observed to be around 17% (43%) at 300 K (50 K). On the other hand, an increasing exchange bias effect on decreasing temperature has been encountered when field cooling (3T) the oxidized Ni@(NiO,Ni(OH)2) nanowires below 100 K along their parallel lengths.

description: The mixed-anion compound with composition Sr2VO3Cl has been synthesized for the first time, using the conventional high-temperature solid-state synthesis technique in a closed silica ampule under inert conditions. This compound belongs to the known Sr2TmO3Cl (Tm = Sc, Mn, Fe, Co, Ni) family, but with Tm = V. All homologues within this family can be described with the tetragonal space group P4/nmm (No. 129); from a Rietveld refinement of powder X-ray diffraction data on the Tm = V homologue, the unit cell parameters were determined to a = 3.95974(8) and c = 14.0660(4) Å, and the atomic parameters in the crystal structure could be estimated. The synthesized powder is black, implying that the compound is a semiconductor. The magnetic investigations suggest that Sr2VO3Cl is a paramagnet at high temperatures, exhibiting a μeff = 2.0 μB V-1 and antiferromagnetic (AFM) interactions between the magnetic vanadium spins (θCW = −50 K), in line with the V-O-V advantageous super-exchange paths in the V-O layers. Specific heat capacity studies indicate two small anomalies around 5 and 35 K, which however are not associated with long-range magnetic ordering. 35Cl ss-NMR investigations suggest a slow spin freezing below 4.2 K resulting in a glassy-like spin ground state.

description: To investigate the influence of crosslinking methods on the releasing performance of hybrid hydrogels, we synthesized two systems consisting of Graphene oxide (GO) as a functional element and alginate as polymer counterpart by means of ionic gelation (physical method, 𝐻𝑃𝐴−𝐺𝑂) and radical polymerization (chemical method, 𝐻𝐶𝐴−𝐺𝑂). Formulations were optimized to maximize the GO content (2.0 and 1.15% for 𝐻𝑃𝐴−𝐺𝑂 and 𝐻𝐶𝐴−𝐺𝑂, respectively) and Curcumin (CUR) was loaded as a model drug at 2.5, 5.0, and 7.5% (by weight). The physico-chemical characterization confirmed the homogeneous incorporation of GO within the polymer network and the enhanced thermal stability of hybrid vs. blank hydrogels. The determination of swelling profiles showed a higher swelling degree for 𝐻𝐶𝐴−𝐺𝑂 and a marked pH responsivity due to the COOH functionalities. Moreover, the application of external voltages modified the water affinity of 𝐻𝐶𝐴−𝐺𝑂, while they accelerated the degradation of 𝐻𝑃𝐴−𝐺𝑂 due to the disruption of the crosslinking points and the partial dissolution of alginate. The evaluation of release profiles, extensively analysed by the application of semi-empirical mathematical models, showed a sustained release from hybrid hydrogels, and the possibility to modulate the releasing amount and rate by electro-stimulation of 𝐻𝐶𝐴−𝐺𝑂.
Environment-Assisted Invariance Does Not Necessitate Born’s Rule for Quantum Measurement

description: The argument of environment-assisted invariance (known as envariance) implying Born’s rule is widely used in models for quantum measurement to reason that they must yield the correct statistics, specifically for linear models. However, it has recently been shown that linear collapse models can never give rise to Born’s rule. Here, we address this apparent contradiction and point out an inconsistency in the assumptions underlying the arguments based on envariance. We use a construction in which the role of the measurement machine is made explicit and shows that the presence of envariance does not imply that every measurement will behave according to Born’s rule. Rather, it implies that every quantum state allows a measurement machine to be constructed, which yields Born’s rule when measuring that particular state. This resolves the paradox and is in agreement with the recent result of objective collapse models necessarily being nonlinear.

description: We show that, in the first or second order orthonormal frame formalism, black hole entropy is the horizon Noether charge for a combination of diffeomorphism and local Lorentz symmetry involving the Lie derivative of the frame. The Noether charge for diffeomorphisms alone is unsuitable, since a regular frame cannot be invariant under the flow of the Killing field at the bifurcation surface. We apply this formalism to Lagrangians polynomial in wedge products of the frame field 1-form and curvature 2-form, including general relativity, Lovelock gravity, and "topological" terms in four dimensions.

description: Thermoelectric modules can convert waste heat directly into useful electricity, providing a clean and sustainable way to use fossil energy more efficiently. Mg3Sb2-based alloys have recently attracted considerable interest from the thermoelectric community due to their nontoxic nature, abundance of constituent elements and excellent mechanical and thermoelectric properties. However, robust modules based on Mg3Sb2 have progressed less rapidly. Here, we develop multiple-pair thermoelectric modules consisting of both n-type and p-type Mg3Sb2-based alloys. Thermoelectric legs based on the same parent fit into each other in terms of thermomechanical properties, facilitating module fabrication and ensuring low thermal stress. By adopting a suitable diffusion barrier layer and developing a new joining technique, an integrated all-Mg3Sb2-based module demonstrates a high efficiency of 7.5% at a temperature difference of 380 K, exceeding the state-of-the-art same-parent thermoelectric modules. Moreover, the efficiency remains stable during 150 thermal cycling shocks (∼225 h), demonstrating excellent module reliability.

description: A preliminary determination of the Dirac phase in the PMNS matrix is $\dell\approx -\fracπ{2}$. A rather accurately determined Jarlskog invariant $J$ in the CKM matrix is close to the maximum. Since the phases in the CKM and PMNS matrices will be accurately determined in the future, it is an interesting problem to relate these two phases. This can be achieved in a families-unified grand unification if the weak CP violation is introduced spontaneously {\it à la} Froggatt and Nielsen at a high energy scale, where only one meaningful Dirac CP phase appears.

Towards a World Where Many Worlds Fit: The Black Consciousness Movement as Ontological Resistance
Creators: name: Kinoti, Kyende
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: This thesis looks at the Black Consciousness Movement (BCM) which was an anti-apartheid movement that emerged in South Africa during the 1970s. The thesis aims to showcase how the Black Consciousness Movement’s approach to counteracting white supremacy in the apartheid state can be understood as ontological resistance. I argue that the BCM recognized that the suppression of blacks was the foundation of European hegemony. Therefore, it was not possible to try to integrate into European values or to try to adapt European systems - that is, capitalism or socialism- to benefit blacks. Instead, the BCM began to pursue a world which would be primarily cultivated according to the values and needs of black communities. This thesis will explore how this approach by the BCM was contributing to, in the famous words of the Zapatistas, “a world where many worlds fit.”
RNA-Seq analysis and transcriptome assembly for Blackberry (Rubus sp. Var. Lochness) fruit
Creators: name: BGI
Publisher: name: CNGB
Year: 2014

description: There is an increasing interest in berries, especially blackberries in the diet, because of recent reports of their health benefits due to their high content of flavonoids. A broad range of genomic tools are available for other Rosaceae species but these tools are still lacking in the Rubus genus, thus limiting gene discovery and the breeding of improved varieties. De novo RNA-seq of blackberry grown under field conditions was performed using Illumina Hiseq 2000. Almost 9 billion nucleotide bases were sequenced in total. Following assembly, 42,062 unigenes were detected. For functional annotation, 33,040 (NR), 32,762 (NT), 21,932 (Swiss-Prot), 20,134 (KEGG), 13,676 (COG), 24,168 (GO) unigenes were annotated using different databases; in total 34,552 annotated unigenes were identified. For protein prediction analysis, the number of coding DNA sequences (CDS) that mapped to the protein database was 32,540. Non redundant (NR), annotation showed that 25,418 genes (77.5%) has the highest similarity with Fragaria vesca subespecies vesca. A reanalysis was undertaken by aligning the reads with this reference genome for a deeper analysis of the transcriptome. In this reanalysis, 67,845 SNP were found, 462 alternative splicing events were analyzed, and the distribution of the reads on the reference chromosomes was established. We demonstrated that de novo assembly, using Trinity and later annotation with Blast using different databases, were complementary to alignment to the reference sequence using SOAPaligner/SOAP2. The Fragaria reference genome belongs to a species of the same family as blackberry (Rosaceae) but to a different genus. Since blackberries are tetraploids, the possibility of artefactual gene chimeras resulting from mis-assembly was tested with one of the genes sequenced by RNAseq, Chalcone Synthase (CHS). cDNAs encoding this protein gene were cloned and sequenced. Primers designed on the assembled sequences accurately distinguished different contigs, at least for the chalcone synthase genes. We prepared and analysed transcriptome data from ripe blackberries, for which prior genomic information was limited. This sequence information will improve the knowledge of this important and healthy fruit, providing an invaluable new tool for biological research.
The Role of Social Isolation as a Predetermining Factor for Postpartum Depression Development: A Literature Review
Creators: name: Caroline-Grace Hawes
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Postpartum depression is a globally prevalent, widespread issue among women following childbirth that primarily causes severe, distressing reverberations in the mother. Additionally, these afflictions endured by the mother can further impact the infant, spouse, and other individuals in the household. Research has identified numerous risk factors for postpartum depression; however, the role of social isolation in the development of postpartum depression is underrepresented in literature. The purpose of this literature review is to identify the role of social isolation as a predetermining factor for the development of postpartum depression. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were utilized to conduct and guide a systematic search of available literature. A total of 22 articles that were specific to the development of postpartum depression and that primarily focused on social isolation in regard to development of postpartum depression were included for review. After a thorough review of the literature, four key themes emerged. The four key themes identified included a lack of support, individuals or groups who have commonly become marginalized or isolated in society (i.e. immigrants, refugees, etc.), a loss of identity, and the fear of being an unfit mother. These themes correlated directly with the relationship of social isolation being a predetermined factor for the development of postpartum depression. Future research is needed to ascertain this correlation, and further investigation should identify specific interventions to prevent the development of postpartum depression.

description: The research objective is to analyse the consequences that recent crises have had for multilateral organizations, to what extent they fostered a transformation of response mechanisms and whether this transformation has contributed to strengthening the institution and improving its response to new crises. We analyse and compare the role of two specific International Organizations (IOs), the World Health Organization and the International Organization of Migration, in recent major transnational crises: the COVID-19 pandemic and the migration crisis caused by Russian aggression against Ukraine. Two complementary strands of the scientific literature are taken into account: Studies analysing the functioning and performance of IOs and the literature on crisis management. In each case study, we describe the IOs’ institutional designs and the characteristics of the policy regimes in which the IOs operate. Then we assess the response given to the crises, distinguishing between planned measures designed to provide an immediate response and resilience measures for future crises. We end with a comparative assessment of the performance of these two IOs in the face of these crises and their capacity to learn lessons from them to deal with future crises.

description: The healthcare industry relies heavily on an efficient and responsive workforce to deliver quality patient care. However, with increasing demand, aging populations, workforce shortages, and fluctuating workloads, healthcare systems worldwide are under strain. Traditional management approaches often struggle to address these dynamic challenges. In response, advanced algorithms powered by artificial intelligence (AI) and machine learning (ML) are emerging as vital tools for healthcare workforce management. These technologies enable predictive staffing, optimize scheduling, enhance operational efficiency, and improve employee satisfaction. By analyzing vast data sets from electronic health records, hospital operations, and staff preferences, AI algorithms can forecast workforce needs, match the right skillsets to the right tasks, and reduce administrative burdens. This paper explores how advanced algorithms are revolutionizing workforce management in healthcare, discusses their practical applications, and addresses the ethical and organizational challenges associated with their adoption.

description: The presence of excess emission at 3.6--8.0 $μ$m was investigated in a sample of 27 binary systems located in two nearby star-forming regions, Taurus and Ophiuchus, by using Spitzer/Infrared Array Camera (IRAC) archival data. Angular (Projected) separations for the binaries are greater than 2"($\sim$280 AU), which allowed us to perform spatially resolved photometry of individual primary and secondary sources. The measured occurrence of infrared excess suggests that binarity plays a role in the evolution of circumstellar disks, even at such wide binary separations. Most of the binaries have excess emission from both the circumprimary and circumsecondary disks, or show photospheric levels for both components at all four wavelengths of IRAC. On the other hand, four systems ($17^{+11}_{-8}$%, designated by "mixed" systems) exhibit excess emission from a single binary component. This ratio is significantly smaller than that predicted by the random pairing of single stars, suggesting that circumprimary and circumsecondary disks are synchronously dispersed. In addition, the excess frequencies (EFs) of primary and secondary sources with a projected distance of $a_{\rm p}$$\simeq$280--450 AU are $100^{+0}_{-17}$% and $91^{+8}_{-18}$%, respectively, and significantly higher than that of single stars ($70 \pm 5$%). We made a simple model describing the EF distribution as a function of the disk outer radius, $R_{\rm out}$. Comparisons with observations using the Kolmogorov-Smirnov test show that the observational data are consistent with the model when the $\rm{EF} \simeq 1$ region is found at $R_{\rm out}$$\sim$30--100 AU. This disk radius is smaller than that typically estimated for single stars. The high EF of circumstellar disks with these radii may indicate a prolonged lifetime of dust in binary systems possibly because smaller disks counteract mass loss by photoevaporation.

description: Explainable AI (XAI) systems are sociotechnical in nature; thus, they are subject to the sociotechnical gap--divide between the technical affordances and the social needs. However, charting this gap is challenging. In the context of XAI, we argue that charting the gap improves our problem understanding, which can reflexively provide actionable insights to improve explainability. Utilizing two case studies in distinct domains, we empirically derive a framework that facilitates systematic charting of the sociotechnical gap by connecting AI guidelines in the context of XAI and elucidating how to use them to address the gap. We apply the framework to a third case in a new domain, showcasing its affordances. Finally, we discuss conceptual implications of the framework, share practical considerations in its operationalization, and offer guidance on transferring it to new contexts. By making conceptual and practical contributions to understanding the sociotechnical gap in XAI, the framework expands the XAI design space.

description: We present new algorithms for Personalized PageRank estimation and Personalized PageRank search. First, for the problem of estimating Personalized PageRank (PPR) from a source distribution to a target node, we present a new bidirectional estimator with simple yet strong guarantees on correctness and performance, and 3x to 8x speedup over existing estimators in experiments on a diverse set of networks. Moreover, it has a clean algebraic structure which enables it to be used as a primitive for the Personalized PageRank Search problem: Given a network like Facebook, a query like "people named John", and a searching user, return the top nodes in the network ranked by PPR from the perspective of the searching user. Previous solutions either score all nodes or score candidate nodes one at a time, which is prohibitively slow for large candidate sets. We develop a new algorithm based on our bidirectional PPR estimator which identifies the most relevant results by sampling candidates based on their PPR; this is the first solution to PPR search that can find the best results without iterating through the set of all candidate results. Finally, by combining PPR sampling with sequential PPR estimation and Monte Carlo, we develop practical algorithms for PPR search, and we show via experiments that our algorithms are efficient on networks with billions of edges.

description: Disjoint $n$-amalgamation is a condition on a complete first-order theory specifying that certain locally consistent families of types are also globally consistent. In this paper, we show that if a countably categorical theory $T$ admits an expansion with disjoint $n$-amalgamation for all $n$, then $T$ is pseudofinite. All theories which admit an expansion with disjoint $n$-amalgamation for all $n$ are simple, but the method can be extended, using filtrations of Fraïssé classes, to show that certain non-simple theories are pseudofinite. As case studies, we examine two generic theories of equivalence relations, $T^*_{\text{feq}}$ and $T_{\text{CPZ}}$, and show that both are pseudofinite. The theories $T^*_{\text{feq}}$ and $T_{\text{CPZ}}$ are not simple, but they are NSOP$_1$. This is established here for $T_{\text{CPZ}}$ for the first time.

Creators: name: Hohmann, Nikolas

Publisher: name: IEEE
Year: 2023

description: Planning flight paths for unmanned aerial vehicles in urban areas requires consideration of safety, legal, and economic aspects as well as attention to social factors for gaining public acceptance. To solve this many-objective path planning problem in the three-dimensional space, we propose a hybrid framework combining an exact Dijkstra search and a metaheuristic evolutionary optimization. Given a start and an endpoint, we optimize a path regarding the risk in case of a system failure, the radio signal disturbance between the aerial vehicle and a ground station, the energy consumption, and the noise immission on city residents. The optimization includes constraints for static obstacle collision avoidance and compliance with the minimum flight altitude. The result is a set of smooth and three-dimensional paths that realize different trade-offs between the defined objectives. As an example, we consider an urban transportation application for aerial vehicles in San Francisco. For all tests, we use real-world data from OpenStreetMap. In a statistical evaluation, we test the efficiency of our framework against different state-of-the-art optimizers. Moreover, we extend the framework with two features that allow the user to integrate arbitrary objectives and unknown scenarios into the path planning framework.
Effects of Intermittent Preventive Therapy in pregnancy (IPTp) with Sulfadoxine-Pyrimethamine on the Maternal Carriage of Group B Streptococcus and Enterococcus faecalis

description:  Malaria is a parasitic infectious disease transmitted by the bite of infected mosquitoes that is endemic to many parts of sub-Saharan Africa, including Malawi. Malaria infections during pregnancy can be harmful to the health outcomes of pregnant women and their fetuses, leading to low birth weights, maternal anemia, or stillbirth. To prevent and treat malaria infection during pregnancy and avert these poor health outcomes, the accepted course of treatment has been Intermittent Preventive Therapy in pregnancy (IPTp) with Sulfadoxine-Pyrimethamine (SP) from early in the second trimester until delivery. In recent years, the malaria parasite has grown resistant to SP and a new alternative drug, dihydroartemisinin-piperaquine (DP), has been introduced as an alternative. Paradoxically, although the malaria parasite has demonstrated increased resistance to SP in recent years, women who take SP during pregnancy and their babies continue to be protected against poor pregnancy and birth outcomes. Since SP is absorbed through the gut, this study examines if the protective effects of SP act on the gut by reducing pathogen carriage and improving nutrient uptake. We focused on the effects of SP on two pathogens in particular, Streptococcus agalactiae (Group B Streptococcus, GBS) and Enterococcus faecalis. Using extracted DNA from stool samples from women in Malawi (n=89), we investigated the presence of each pathogen using qPCR. We did not find a clear association between either drug and E. faecalis or GBS. Women at their second pregnancy (secundigravidae) had an increased likelihood of E. faecalis infection at baseline (pre-drug) compared to primigravidae, but the relationship was less clear after drug administration. The gravidity results will be discussed in the context of pregnancy immune tolerance. Overall, these results will form part of a greater body of work attempting to identify the malaria-independent mechanism of SP protection.

description: The effect of mutual interaction between dark solitons and dispersive waves is investigated numerically and analytically. The condition of the resonant scattering of dispersive waves on dark solitons is derived and compared against the results of numerical simulations. It is shown that the interaction with intense dispersive waves affects the dynamics of the soltons strongly changing their frequencies and accelerating or decelerating the solitons. It is also demonstrated that two dark solitons can form a cavity for dispersive weaves bouncing between the two dark solitons. The differences of the resonant scattering of the dispersive waves on the dark and bright solitons are discussed. In particular we demonstrate that two dark solitons and dispersive wave bouncing in between them create solitonic cavity with convex "mirrors" unlike the concave "mirror" in case of the bright solitons.

Stadiums of Status: Civic Development, Race, and the Business of Sports in Atlanta, Georgia, 1966-2019

description: On April 15, 1964, Ivan Allen Jr. and other Atlanta dignitaries broke ground on Atlanta-Fulton County Stadium, despite not yet having any professional sports teams to play there. The determination to build a stadium stemmed from Allen’s desire to use sports to enhance the city’s national and international reputation amidst the civil rights movement. Throughout the next 55 years, Atlanta’s political and business leaders used professional sports teams, stadiums, and major sporting events to achieve the same goal. The first wave came in the 1960s, when the city welcomed three professional sports teams, the Braves, the Falcons, and the Hawks. 20 years later, Atlanta won the bid for the 1996 Summer Olympic Games, expanding the city’s profile to all corners of the globe. However, while using games and events to build up the city’s reputation, the construction of stadiums and hosting of events detrimentally affected the city’s impoverished, largely African American lower classes. This legacy heavily influenced the construction of two new stadiums in the 2010s for the Braves and the Falcons, as the city ensured that neither team could build a downtown stadium without investing in the neighborhoods surrounding it. This thesis also covers seminal moments involving race and sports in Atlanta, such as Hank Aaron’s 715th home run and Muhammad Ali lighting the Olympic cauldron, as well as several firsthand interviews, including one with former Atlanta mayor Andrew Young.

description: For over 15 years, the mlpack machine learning library has served as a "swiss army knife" for C++-based machine learning. Its efficient implementations of common and cutting-edge machine learning algorithms have been used in a wide variety of scientific and industrial applications. This paper overviews mlpack 4, a significant upgrade over its predecessor. The library has been significantly refactored and redesigned to facilitate an easier prototyping-to-deployment pipeline, including bindings to other languages (Python, Julia, R, Go, and the command line) that allow prototyping to be seamlessly performed in environments other than C++. mlpack is open-source software, distributed under the permissive 3-clause BSD license; it can be obtained at https://mlpack.org
Spatial correlations of elementary relaxation events in glass-forming liquids

description: The dynamical facilitation scenario, by which localized relaxation events promote nearby relaxation events in an avalanching process, has been suggested as the key mechanism connecting the microscopic and the macroscopic dynamics of structural glasses. Here we investigate the statistical features of this process via the numerical simulation of a model structural glass. First we show that the relaxation dynamics of the system occurs through particle jumps that are irreversible, and that cannot be decomposed in smaller irreversible events. Then we show that each jump does actually trigger an avalanche. The characteristic of this avalanche change on cooling, suggesting that the relaxation dynamics crossovers from a noise dominated regime where jumps do not trigger other relaxation events, to a regime dominated by the facilitation process, where a jump trigger more relaxation events.

Collecting the Art of Vocabulary: Investigating the Use of Attributes in Museums’ Collection Management Systems
Creators: name: Cao, Yuqiao
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: The museum community has limited guidance for collection management plans, and each art museum has to decide on its’ own practice to best accommodate unique collections. The goal of this study is to explore the use of vocabulary for collection descriptions in museums’ digital collection management systems. This study is based on an in-depth questionnaire with collection management staff at museums across North America. The results investigate the use of authorities or local thesauri as attributes and plans to manage and update attribute lists. This study aims to promote communications among the museums community, ensure institutions are on the same page in using and managing attributes, and provide suggestions for attributes as an important collection descriptor to enhance museum collections’ discoverability and accessibility.
Batalin-Tyutin quantization of dynamical boundary of AdS$_2$

description: In a two-dimensional AdS space, a dynamical boundary of AdS space was described by a one-dimensional quantum-mechanical Hamiltonian with a coupling between the bulk and boundary system. In this paper, we present a Lagrangian corresponding to the Hamiltonian through the Legendre transformation with a constraint. In Dirac's constraint analysis, we find two primary constraints without secondary constraints; however, they are fully second-class. In order to make the second-class constraint system into a first-class constraint system, we employ the Batalin-Tyutin Hamiltonian method, where the extended system reduces to the original one for the unitary gauge condition. In the spirit of the AdS/CFT correspondence, it raises a question whether a well-defined extended bulk theory corresponding to the extended boundary theory can exist or not.

description: GHRSST Standards for formatting SST data were presented at the Ocean Best Practices Workshop on 10th October 2023, with a dedicated intervention on Operational Sea-Surface Temperature data retrieved from satellites. Speaker: Ioanna Karagali (DMI) This presentation gave an overview of the operational exploitation of SST derived from satellites. Specific user examples will be given together with an overview of GHRSST. Current GHRSST priorities include high-resolution SST around coasts, improvements in high-latitude SST and feature resolution. The workshop was organised by IOC/ Ocean Best Practices System Steering Group. The OBPS Workshop VII, 2023 explores the 10 selected challenges set by the UN Ocean Decade and the ways that Ocean best practices support some “common” solutions for collective impact. Challenge 7 - Expand the Global Ocean Observing System: Ensure a sustainable ocean observing system across all ocean basins that delivers accessible, timely, and actionable data and information to all users. Operational Sea-Surface Temperature data retrieved from satellites by Anne G. O'Carroll, Jacob L. Høyer, Ioanna Karagali, Chiara Bearzotti, Erika Hayashi and members of the GHRSST International Science Team Sea surface temperature (SST) is a fundamental physical variable for understanding, quantifying and predicting complex interactions between the ocean and the atmosphere. Such processes dictate how heat from the sun is redistributed across the global oceans, directly impacting large- and small-scale weather and climate patterns. The provision of daily maps of global SST for operational systems, climate modelling and the broader scientific community is now a mature and sustained service coordinated by the Group for High Resolution Sea Surface Temperature (GHRSST) and the CEOS SST Virtual Constellation (CEOS SST-VC). GHRSST (http://www.ghrsst.org) is comprised of SST experts representing many communities including space agencies, meteorological agencies and universities around the world. The partnership between GHRSST and the CEOS SST-VC is organised with GHRSST implementing the framework for SST-VC activities. GHRSST coordinates a suite of global high-resolution SST products. Data processing and distribution are organised through Data Assembly Centres and products are provided according to the community agreed GHRSST Data Processing Specification (GDS) V2.0 common specification. SST products rely on a combination of low earth orbit infrared and microwave satellite imagery, geostationary orbit infrared satellite imagery, and in situ data from moored and drifting buoys, Argo floats, and Fiducial Reference Measurements (FRM) for product validation.
The Effect of Patent Expiration on Pharmaceutical Firms’ Research and Development Decisions
Creators: name: Edwards, Zachary
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: How does the expiration of a pharmaceutical firms’ drug patent affect the firms’ R&D decisions? We attempt to answer this question by combining data from the FDA Orange Book dataset on drug patents with firm-level data from the Pharmaprojects database. We utilize a logistic probability model to determine how patent expiration affects the chances that a firm will undertake certain actions to mitigate the negative effects that patent expirations have on revenue streams. In doing so, we find that firms that are nearing patent expiration begin testing of new products and seek new licensing opportunities for existing products, rather than discontinue existing products.
