description: We investigate wether three statements in analysis, that can be proved classically, are realizable in the realizability model of extensional continuous functionals induced by Kleene's second model $K_2$. We prove that a formulation of the Riemann Permutation Theorem as well as the statement that all partially Cauchy sequences are Cauchy cannot be realized in this model, while the statement that the product of two anti-Specker spaces is anti-Specker can be realized.

Year: 2023

description: This Master’s Project serves as a “playbook” style resource guide to help communities and local governments navigate the decision-making and implementation processes related to disc golf course development. By collecting information such as the demand for disc golf, the benefits of disc golf for the community and players, and the cost, spatial requirements, and environmental impact of courses, this report serves as a justification for the implementation of disc golf courses. This report does so by compiling existing research, illustrative overviews of various types of courses in the Triangle region of North Carolina, and a series of nine semi-structured interviews with those involved in course creation and maintenance. The subjects of these interviews include course designers, planners, parks and recreation staff, and industry professionals. Lastly, by providing the reader with a collection of resources, including course design best practices and actionable next steps for course implementation, this guide is intended to be a useful resource for those advocating for disc golf across the country.

description: Cr$^{3+}$ doped spinel compounds AB$_2$O$_4$ with A=Zn, Mg and B=Ga, Al exhibit a long near infrared persistent luminescence when excited with UV or X-rays. In addition, persistent luminescence of ZnGa$_2$O$_4$ and to a lesser extent MgGa$_2$O$_4$, can also be induced by visible light excitation via $^4$A$_2$ $ \rightarrow $ $^4$T$_2$ transition of Cr$^{3+}$, which makes these compounds suitable as biomarkers for in vivo optical imaging of small animals. We correlate this peculiar optical property with the presence of antisite defects, which are present in ZnGa$_2$O$_4$ and MgGa$_2$O$_4$. By using X-ray absorption fine structure (XAFS) spectroscopy, associated with electron paramagnetic resonance (EPR) and optical emission spectroscopy, it is shown that an increase in antisite defects concentration results in a decrease in the Cr-O bond length and the octahedral crystal field energy. A part of the defects are in the close environment of Cr$^{3+}$ ions, as shown by the increasing strain broadening of EPR and XAFS peaks observed upon increasing antisite disorder. It appears that ZnAl$_2$O$_4$, which exhibits the largest crystal field splitting of Cr$^{3+}$ and the smallest antisite disorder, does not show considerable persistent luminescence upon visible light excitation as compared to ZnGa$_2$O$_4$ and MgGa$_2$O$_4$. These results highlight the importance of Cr$^{3+}$ ions with neighboring antisite defects in the mechanism of persistent luminescence exhibited by Cr$^{3+}$ doped AB$_2$O$_4$ spinel compounds.

description: Social feedback plays an important role in human language development and in the vocal ontogeny of non-human animals. A special form of vocal feedback in humans, infant-directed speech – or motherese – facilitates language learning and is socially beneficial by increasing attention and arousal in the child. It is characterized by high pitch, expanded intonation contours and slower speech tempo. Furthermore, the vocal timbre (i.e., “color” of voice) of motherese differs from the timbre of adult-directed speech. In animals, pup-directed vocalizations are very common, especially in females. But so far there is hardly any research on whether there is a similar phenomenon as motherese in animal vocalizations. The greater sac-winged bat, Saccopteryx bilineata, is a vocal production learner with a large vocal repertoire that is acquired during ontogeny. We compared acoustic features between female pup-directed and adult-directed vocalizations and demonstrated that they differed in timbre and peak frequency. Furthermore, we described pup-directed vocalizations of adult males. During the ontogenetic period when pups’ isolation calls (ICs) (used to solicit maternal care) are converging toward each other to form a group signature, adult males also produce ICs. Pups’ ICs are acoustically more similar to those of males from the same social group than to other males. In conclusion, our novel findings indicate that parent-offspring communication in bats is more complex and multifaceted than previously thought, with female pup-directed vocalizations reminiscent of human motherese and male pup-directed vocalizations that may facilitate the transmission of a vocal signature across generations.
The Labyrinth of Central Europe and the World Paradise in Milan Kundera's Ignorance
Creators: name: Píchová, Hana
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Milan Kundera laid out his concept of Central Europe in "The Tragedy of Central Europe" (1984) with unprecedented force and conviction. His defense of the region's political identity and cultural uniqueness as well as its West European connectedness sparked heated polemics among leading intellectuals of the day. Kundera stood solidly at its very center, both as an intellectual and fictional writer. Retrospectively, this prominent role turned out to be short-lived. Central Europe, as a cultural and geographical concept, has all but disappeared from his work and, contrary to expectation, not because of the post-1989 realities but rather because of his artistic goals and ambitions, which have expanded well beyond the borders of Europe. Kundera's novel L'Ignorance (2000) attests to this re-evaluation. It offers a new perspective on the region, no longer privileging its central location but redefining its state of in-betweenness as that of geographic, cultural, and linguistic fluidity. To trace Kundera's development of his concept of Central Europe is to reimagine the once enclosed territory but also to reinvent the adventure that lies ahead of the European novel.
Magnetohydrodynamic Turbulence Powered by Magnetorotational Instability in Nascent Proto-Neutron Stars

description: Magnetorotational instability (MRI) in a convectively-stable layer around the neutrinosphere is simulated by a three-dimensional model of supernova core. To resolve MRI-unstable modes, a thin layer approximation considering only the radial global stratification is adopted. Our intriguing finding is that the convectively-stable layer around the neutrinosphere becomes fully-turbulent due to the MRI and its nonlinear penetration into the strongly-stratified MRI-stable region. The intensity of the MRI-driven turbulence increases with magnetic flux threading the core, but is limited by a free energy stored in the differential rotation. The turbulent neutrinosphere is a natural consequence of rotating core-collapse and could exert a positive impact on the supernova mechanism.

description: Structural rearrangement of liquid Bi in the vicinity of the melting point has been proposed due to the unique temperature invariant sound velocity observed above the melting temperature, the low symmetry of Bi in the solid phase and the necessity of overheating to achieve supercooling. The existence of this structural rearrangement is examined by measurements on supercooled Bi. The sound velocity of liquid Bi was measured into the supercooled region to high accuracy and it was found to be invariant over a temperature range of ca. 60 degrees, from 35 degrees above the melting point to ca. 25 degrees into the supercooled region. The structural origin of this phenomenon was explored by neutron diffraction structural measurements in the supercooled temperature range. These measurements indicate a continuous modification of the short range order in the melt. The structure of the liquid is analyzed within a quasi-crystalline model and is found to evolve continuously, similar to other known liquid pnictide systems. The results are discussed in the context of two competing hypotheses proposed to explain properties of liquid Bi near the melting: (i) liquid bismuth undergoes a structural rearrangement slightly above melting (ii) liquid Bi exhibits a broad maximum in the sound velocity located incidentally at the melting temperature.

description: This paper shows equivalence of several versions of applicative similarity and contextual approximation, and hence also of applicative bisimilarity and contextual equivalence, in LR, the deterministic call-by-need lambda calculus with letrec extended by data constructors, case-expressions and Haskell's seq-operator. LR models an untyped version of the core language of Haskell. The use of bisimilarities simplifies equivalence proofs in calculi and opens a way for more convenient correctness proofs for program transformations. The proof is by a fully abstract and surjective transfer into a call-by-name calculus, which is an extension of Abramsky's lazy lambda calculus. In the latter calculus equivalence of our similarities and contextual approximation can be shown by Howe's method. Similarity is transferred back to LR on the basis of an inductively defined similarity. The translation from the call-by-need letrec calculus into the extended call-by-name lambda calculus is the composition of two translations. The first translation replaces the call-by-need strategy by a call-by-name strategy and its correctness is shown by exploiting infinite trees which emerge by unfolding the letrec expressions. The second translation encodes letrec-expressions by using multi-fixpoint combinators and its correctness is shown syntactically by comparing reductions of both calculi. A further result of this paper is an isomorphism between the mentioned calculi, which is also an identity on letrec-free expressions.

Year: 2017

description: This article deals with a recent defenestration in Prague–a chosen method of suicidal “flight” from windows prevalent in peculiar fashion in both literary and historical representations of Prague.

Bohumil Hrabal not only wrote extensively about defenestration in his fictional and documentary work, but also ended his life by falling out of a hospital window in February 1997. I explore how the ornate windows of Prague’s buildings, rich with history, become complex symbols of the spirit of Prague and its historical and cultural destiny. Hrabal’s final act transcends the personal to encompass the cultural, evoking historical tragedies of Prague and the former Czechoslovakia.
description: Článek pojednává o jedné nedávné pražské „defenestraci“, typu sebevraždy „letem“ z okna, jež je specifickým způsobem odchodu ze života hojně zachyceným v literárních i historických reprezentacích Prahy. Bohumil Hrabal o „defenstraci“ nejen obsáhle psal ve svém fikčním a dokumentárním díle, ale v únoru 1997 také ukončil svůj život skokem z nemocničního okna. V článku se zabývám tím, jak se ozdobná okna pražských budov, prosycených dějinami, stávají komplexními symboly ducha Prahy a jejího historického a kulturního osudu. Hrabalův poslední čin překračuje meze osobního a stává se součástí kulturního fenomenu evokujícího historické tragédie Prahy a bývalého Československa.

description: A fundamental understanding of internationalized education is needed to decide whether to utilize the methodology in innovation instructional frameworks. Internationalized education is described as developing and executing global education programs. As a result, instructors incorporate principles of globalization into curriculum. Instructors facilitate student understanding of the tenets of globalization; incorporate a high-level of engagement; provide opportunities for innovation; extend curriculum beyond traditional modes of instruction; encourage students to use personal and professional experience to express how they understand topical matter; set deadlines and guidelines, but extend exceptions to students or student groups who elevate topical matter by incorporating innovation, reflectivity, and entrepreneurship. Further, improving the execution of innovation in the classroom is critical in providing substantive examples to extend innovative practices to students. Additionally, this expose provides an analytical discourse of content formats that are most effective for online learning for internationalized education. There are many instructional and curriculum design elements that instructors must be aware of when developing internationalized education programs. Likewise, institutions must focus on learner needs with regard to preparing students for the workforce.

description: We investigate quantum control of an oscillator mode off-resonantly coupled to an ancillary qubit. In the strong dispersive regime, we may drive the qubit conditioned on number states of the oscillator, which together with displacement operations can achieve universal control of the oscillator. Based on our proof of universal control, we provide explicit constructions for arbitrary state preparation and arbitrary unitary operation of the oscillator. Moreover, we present an efficient procedure to prepare the number state $\left|n\right\rangle$ using only $O\left(\sqrt{n}\right)$ operations. We also compare our scheme with known quantum control protocols for coupled qubit-oscillator systems. This universal control scheme of the oscillator can readily be implemented using superconducting circuits.

description: Foodborne infection with Listeria causes potentially life-threatening disease listeriosis. Listeria monocytogenes is widely recognized as the only species of public health concern, and the closely related species Listeria innocua is commonly used by the food industry as an indicator to identify environmental conditions that allow for presence, growth, and persistence of Listeria spp. in general. In our study, we analyze the occurrence of Listeria spp. in a farm-to-fork approach in a poultry production chain in Egypt and identify bacterial entry gates and transmission systems. Prevalence of Listeria innocua at the three production stages (farm, slaughterhouse, food products) ranged from 11% to 28%. The pathogenic species Listeria monocytogenes was not detected, and Listeria innocua strains under study did not show genetic virulence determinants. However, the close genetic relatedness of Listeria innocua isolates (maximum 63 SNP differences) indicated cross-contamination between all stages from farm to final food product. Based on these results, chicken can be seen as a natural source of Listeria. Last but not least, sanitary measures during production should be reassessed to prevent bacterial contamination from entering the food chain and to consequently prevent human listeriosis infections. For this purpose, surveillance must not be restricted to pathogenic species.

description: The formation of complex organic molecules (COMs) in protostellar environments is a hotly debated topic. In particular, the relative importance of the gas phase processes as compared to a direct formation of COMs on the dust grain surfaces is so far unknown. We report here the first high-resolution images of acetaldehyde (CH$_3$CHO) emission towards the chemically rich protostellar shock L1157-B1, obtained at 2 mm with the IRAM Plateau de Bure interferometer. Six blueshifted CH$_3$CHO lines with $E_{\rm u}$ = 26-35 K have been detected. The acetaldehyde spatial distribution follows the young ($\sim$ 2000 yr) outflow cavity produced by the impact of the jet with the ambient medium, indicating that this COM is closely associated with the region enriched by iced species evaporated from dust mantles and released into the gas phase. A high CH$_3$CHO relative abundance, 2-3 $\times$ 10$^{-8}$, is inferred, similarly to what found in hot-corinos. Astrochemical modelling indicates that gas phase reactions can produce the observed quantity of acetaldehyde only if a large fraction of carbon, of the order of 0.1%, is locked into iced hydrocarbons.

description: Education as a social determinant of health largely impacts the quality of life and overall health of disadvantaged communities. Specifically, gaps in health disparities exist between reading levels in Black, Hispanic, and White students, and economically disadvantaged and non-economically disadvantaged students in the Durham Public Schools (DPS). Bulldog Reads is a program that goes beyond the existing DINE implementation to combine nutrition and literacy lessons for kindergarten through fifth grade students at Bethesda Elementary School (BES). Utilizing existing school and community resources, program implementation will be cost effective and annual expenses will be minimal. Bulldog Reads will be designed, implemented, evaluated, and sustained through engaging partnerships with various local organizations and nonprofit stakeholders with consideration of continuous quality improvement of the program and engagement. Success will be defined by higher reading ability along with increased nutrition awareness tracked by BMI and carotenoid presence in students’ skin.
The Pain of Rejection: Using Photography to Prevent Erasure and Find Self-Acceptance

description: Most people are guilty of worrying about what others think of them, seeking approval, and finding comfort when accepted, their lives validated. In "City of Night", John Rechy suggests that these behaviors are characteristic of most people but also contribute to pain in those who feel rejected by others. Rechy says the marginalized characters exist as a culture separate from the dominant culture, the night distinct from the day, with people resisting, and advocating for visibility. In "NEIL: Masquerade", the unnamed narrator and Neil try to find acceptance from one another through photography and dressing up, but neither can validate the other, causing both to feel rejected, with both behaving aggressively in response. Neil fails to understand that the narrator is interested in dressing up to appear more attractive and valued and inadvertently invalidates the narrator's desires, making them feel unaccepted. Similarly, the narrator invalidates Neil for his desire to be perceived by others as someone strong and dominant. The narrator refers to dressing up as "costuming" and feels Neil's desire to find acceptance by photographing people with similar sexual preferences is an attempt to rationalize socially unacceptable sexual fantasies. Neil feels rejected for his gender and sexual identity, and when their shared interest in finding acceptance through photography brings them together again, they lash out violently, furthering the already existing harm. They cannot recognize that they are both a product of their place within society, and grow to resent each other when they could have worked together.

description: We present a study of the magneto-ionic medium in the Whirlpool galaxy (M51) using new wide-band multi-configuration polarization data at L band (1-2 GHz) obtained at the Karl G. Jansky Very Large Array. By fitting the observed diffuse complex polarization $Q$+$iU$ as a function of wavelength directly to various depolarization models, we find that polarized emission from M51 at 1-2 GHz originates from the top of the synchrotron disk and then experiences Faraday rotation in the near-side thermal halo of the galaxy. Thus, the scale height of the thermal gas must exceed that of the synchrotron emitting gas at L band. The observed Faraday depth distribution at L band is consistent with a halo field that comprises of a plane-parallel bisymmetric component and a vertical component which produces a Faraday rotation of $\sim$ $-$9 rad m$^{-2}$. The derived rotation measure structure functions indicate a characteristic scale of rotation measure fluctuations of less than 560 pc in the disk and approximately 1 kpc in the halo. The outer scale of turbulence of 1 kpc found in the halo of M51 is consistent with superbubbles and the Parker instability being the main energy injection mechanisms in galactic halos.

description: Introduction: Adolescent vaping remains a problem in the United States, yet little is known about what health warning themes most discourage vaping among adolescents. We sought to identify the most compelling themes for vaping warnings for US adolescents. Methods: Participants were a national probability sample of 623 US adolescents aged 13-17 years, recruited in the summer of 2020. Adolescents were randomized to one of the five warning message themes about the potential health effects of vaping: 1. chemical harms, 2. lung harms, 3. Coronavirus Disease 2019 (COVID-19) harms, 4. nicotine addiction, or 5. control (messages about vape litter). The primary outcome was perceived message effectiveness (PME; 3-item scale). Secondary outcomes were negative affect (fear), attention, anticipated social interactions, and message novelty. Results: Adolescents rated the chemical, lung, and COVID-19 harms warning messages higher on PME than nicotine addiction and control (all p <. 05), while nicotine addiction was rated higher than control (p <. 05). The chemical, lung, and COVID-19 harms warning themes also elicited greater negative affect than nicotine addiction and control (all p <. 05). For all other secondary outcomes, the COVID-19 harms warning message theme was rated higher than nicotine addiction and control (all p <. 05). Conclusion: Adolescents perceived warning message themes about lung, chemical and COVID-19 health effects of vaping as more effective than nicotine addiction. To discourage vaping, the FDA and others should communicate to youth about the health effects of vaping beyond nicotine addiction. Implications: Adolescents rated warning message themes about the lung, chemical, and COVID-19 health effects of vaping as more effective than nicotine addiction, while nicotine addiction was rated as more effective than control themes about vaping litter. To discourage vaping among adolescents, health messaging should expand message themes to communicate about a broader set of health effects of vaping beyond nicotine addiction.

Hiding in plain sight: An abundance of compact massive spheroids in the local Universe

description: It has been widely remarked that compact, massive, elliptical-like galaxies are abundant at high redshifts but exceedingly rare in the Universe today, implying significant evolution such that their sizes at z ~ 2+/-0.6 have increased by factors of 3 to 6 to become today's massive elliptical galaxies. These claims have been based on studies which measured the half-light radii of galaxies as though they are all single component systems. Here we identify 21 spheroidal stellar systems within 90 Mpc that have half-light, major-axis radii R_e < ~2 kpc, stellar masses 0.7x10^{11} < M_*/M_Sun < 1.4x10^{11}, and Sersic indices typically around a value of n=2 to 3. This abundance of compact, massive spheroids in our own backyard - with a number density of 6.9x10^{-6} / Mpc^3 (or 3.5x10^{-5} / Mpc^3 per unit dex in stellar mass) - and with the same physical properties as the high-redshift galaxies, had been over-looked because they are encased in stellar disks which usually result in `galaxy' sizes notably larger than 2 kpc. Moreover, this number density is a lower limit because it has not come from a volume-limited sample. The actual density may be closer to 10^{-4} / Mpc^3, although further work is required to confirm this. We therefore conclude that not all massive `spheroids' have undergone dramatic structural and size evolution since z ~ 2+/-0.6. Given that the bulges of local early-type disk galaxies are known to consist of predominantly old stars which existed at z ~ 2, it seems likely that some of the observed high redshift spheroids did not increase in size by building (3D) triaxial envelopes as commonly advocated, and that the growth of (2D) disks has also been important over the past 9-11 billion years.

description: Education Access and Quality, a Social Determinant of Health (SDoH), influences life expectancy, morbidity, health behaviors, employment, and income. Engagement in diabetes prevention education during adolescent years can influence health behaviors and outcomes. To increase physical health and nutrition wellness knowledge in middle school students' health status and slow or stop the onset of diabetes in Durham County an evidence based diabetes prevention education program will be implemented at one middle school pilot site in Durham County Public Schools. Utilizing a multitiered approach accounting for cultural, environmental, and economic conditions will have the most significant impact on reducing diabetes, which is a top health priority in Durham County, NC. Quantitative and qualitative methods will be employed to assess student knowledge and health behaviors.
Keywords: North Carolina, Durham County, social determinants of health, education access and quality, diabetes prevention education, middle school.

description: We show that due to the ρparameter bound and the Landau pole limit, the reduced 3-3-1 model is unrealistic, while due to the ρparameter and FCNCs bounds, the simple 3-3-1 model is experimentally unfavored. All such conditions strictly constrain the gauge symmetry breaking scales of the minimal 3-3-1 model with three scalar triplets.
