description: Heat produced during a reset operation is meant to show a fundamental bound known as Landauer limit, while simple switch operations have an expected minimum amount of produced heat equal to zero. However, in both cases, present-day technology realizations dissipate far beyond these theoretical limits. In this paper we present a study based on molecular dynamics simulations, where reset and switch protocols are applied on a graphene buckled ribbon, employed here as a nano electromechanical switch working at the thermodynamic limit.

description: It has become increasingly clear that COVID-19 is transmitted between individuals. It stands to reason that the spread of the virus depends on sociocultural ecologies that facilitate or inhibit social contact. In particular, the community-level tendency to engage with strangers and freely choose friends, called relational mobility, creates increased opportunities to interact with a larger and more variable range of other people. It may therefore be associated with a faster spread of infectious diseases, including COVID-19. Here, we tested this possibility by analyzing growth curves of confirmed cases of and deaths due to COVID-19 in the first 30 days of the outbreaks in 39 countries. We found that growth was significantly accelerated as a function of a country-wise measure of relational mobility. This relationship was robust either with or without a set of control variables, including demographic variables, reporting bias, testing availability, and cultural dimensions of individualism, tightness, and government efficiency. Policy implications are also discussed.

description: It’s difficult to define the “landscape category” and it’s very difficult to illustrate the relationship between economy and landscape. The landscape’s definition is changed, but the selection of territories to safeguard isn’t changed enough. Today is important to considerate the selection of one landscape’s heritage like the result of a multiple choice and not an individual choice.

Microbiological analysis of a humanized oral microbiome murine model
Creators: name: Mason, Matthew Robert
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Aims: Oral bacteria are key players in periodontitis etiology. However, mechanistic studies of their pathogenicity are hampered by the lack of animal models that recapitulate the human oral microbiota. This study aimed at developing a ‘humanized’ murine model of the oral microbiome. Materials and Methods: Full mouth supra and subgingival plaque samples were collected from periodontally healthy (H, n=1) and periodontitis (P, n=2) donors. Each donor sample was transplanted by oral gavage into five BALB/c germ free mice. Inoculated mice were sampled via oral swabs at 1, 7, 28, and 42 days post-transplantation. On day 42, a single silk ligature was installed between the first and second maxillary right molars. After 10 days, ligatures were removed, animals were sacrificed, maxillas were collected for micro-CT analysis, and linear measurements were compared between groups using non-parametric tests. The microbial composition of all oral swabs and ligatures was determined using 16S rRNA sequencing (MiSeq, Illumina) and analyzed using the ProbeSEQ pipeline. Results: Human microbial colonization was observed in the oral cavity of inoculated germ free mice at all time-points. Samples from H donors harbored 66% of Streptococcus sp., a genus that also predominated the oral cavity of H-inoculated mice at day 42, ranging from 19%-71%. Streptococcus were also abundant in P-donor samples, comprising 19% of the microbiota and dominated the oral cavity of the P-inoculated mice (67-97% of the microbiota). Ligature placement led to an increase in bacterial diversity, with Fusobacterium sp., Veillonella sp. and Haemophilus sp. representing up to 12%, 67% and 77% of the sample microbial composition, respectively. The number of total OTUs in the healthy group ranged from 64 to 149; whereas, the number of total OTUs in the periodontitis group ranged from 16 to 20. In contrast to the original donor samples, the healthy group had a significantly increased number of species at 42 days (p=0.0477, Wilcoxon). Subsequently, the number of new OTUs detected in the healthy group ranged from 18 to 51;, whereas, the number of new OTUs detected in the periodontitis group ranged from 3 to 5. The number of new OTUs in the healthy group was also significantly more than the diseased group (p=o.0497, Wilcoxon). Conclusions: Human oral microbiota can colonize germ-free mice, however further development of this model is needed for a better representation of the microbiome typically observed in periodontitis patients.

description: The landscape is perception, it is a subject vision which changes in the time and in the look of the person who observe it. Landscape and photography have a strong connection: the aesthetic, emotional, problematic or virtuous aspects of the first (landscape) are synthesized and “immobilized” in the second one (photography). A verbal and visual dialog with Nicola Amato traces this symbiosis’ relationship between landscape and photography and illustrates the peculiar’s characters of an important Italian area: the Puglia.

Low-derivative operators of the Standard Model effective field theory via Hilbert series methods

description: In this work, we explore an extension of Hilbert series techniques to count operators that include derivatives. For sufficiently low-derivative operators, we find an algorithm that gives the number of invariant operators, properly accounting for redundancies due to the equations of motion and integration by parts. Specifically, the technique can be applied whenever there is only one Lorentz invariant for a given partitioning of derivatives among the fields. At higher numbers of derivatives, equation of motion redundancies can be removed, but the increased number of Lorentz contractions spoils the subtraction of integration by parts redundancies. While restricted, this technique is sufficient to automatically generate the complete set of invariant operators of the Standard Model effective field theory for dimensions 6 and 7 (for arbitrary numbers of flavors). At dimension 8, the algorithm does not automatically generate the complete operator set; however, it suffices for all but five classes of operators. For these remaining classes, there is a well defined procedure to manually determine the number of invariants. Using these methods, we thereby derive the set of 535 dimension-8 $N_f = 1$ operators.

Our results show that the presence of inert crowders has a non-nontrivial effect on the dynamics of the network and, consequently, that effective modeling efforts aiming at a general understanding of the behavior of biochemical networks in vivo should be stochastic in nature and based on an explicit representation of both spatial confinement and macromolecular crowding.

Identificación del perjuicio indemnizable en acciones consecutivas (follow-on) en caso de cárteles: de la infracción (y sanción) a la compensación del daño

description: Las acciones consecutivas para la compensación del daño causado por cárteles representan el tránsito de la infracción de la prohibición de cárteles (declarada por las autoridades de competencia) a la indemnización de los perjuicios provocados por la conducta de los infractores. Corresponde al perjudicado que interpone la acción indemnizatoria la prueba del daño y su conexión causal con la conducta antijurídica declarada por la autoridad de competencia. Frecuentemente, la constatación e identificación del daño sufrido se subsumirá en la cuantificación del mismo que figure en las pruebas aportadas por el demandante. Aún así, puede ocurrir que esa prueba no resulte convincente al tribunal, con lo que cualquier decisión deberá ir precedida de la identificación del posible daño provocado por el cártel. La decisión previa de la autoridad de competencia no suele declarar ni acreditar los efectos del cártel en el mercado, aunque en la misma pueden contenerse pruebas o indicios de la producción de daños. En todo caso, la eventual presunción (judicial o legal) del daño es una presunción que el demandado puede rebatir. Aunque los cárteles que no provocan daño sean excepcionales, son una posibilidad, y debe reconocerse a las empresas partícipes en los cárteles el derecho a probar el sobrecoste cero. De modo que, cuando la existencia del daño no se extraiga de la decisión de la autoridad de competencia (como ocurría, por ejemplo, en el cártel del azúcar o en el cártel de los sobres de papel), la salvaguarda del derecho de defensa exige permitir al demandado la prueba de la ausencia de sobrecoste, basándose en datos objetivos y de mercado (que no estén afectados por la infracción).

description: Leamer's 1983 paper Let's Take the Con out of Econometrics is credited with ushering in the Credibility revolution in economics. Since that point, many fields including economics have been found to harbor a large number of papers littered with QRPs, unreplicable results, literatures replete with evidence for publication bias, and so on. One potential driver of unreliable science is obeisance to arbitrary significance criteria; a recently proposed solution is to scale critical values to control the rate of false positives. We aim to assess, using all preprints uploaded to the NBER preprint server until March 2020, whether the economic literature yields significant results with this solution in mind. In addition, we aim to assess the evidence for a number of QRPs.
Nonclassical states from the joint statistics of simultaneous measurements

Publisher: name: arXiv
Year: 2015
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Nonclassicality cannot be a single-observable property since the statistics of any quantum observable is compatible with classical physics. We develop a general procedure to reveal nonclassical behavior from the joint measurement of multiple observables. This requires enlarged spaces and couplings with auxiliary degrees of freedom so it must be followed by an inversion procedure to infer system properties from the observed statistics. In particular this discloses nonclassical properties of standard examples of classical-like behavior, such as SU(2) and Glauber coherent states. Moreover, when combined with other criteria it would imply that every quantum state would be nonclassical.

Potential EU Economic Sanctions in Hungary: An Evaluation
Creators: name: Ding, Olivia
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Hungary’s economic relationship with the European Union is one that may be characterized by asymmetrical interdependence. Recent events in Hungary suggest an advance of illiberal governance practices in Hungary, which would contradict with stated EU interests in promoting liberal democracy and rule of law. This paper seeks to provide some explanation regarding why economic sanctions from the EU may not be enough threat to deter Hungary from exhibiting behavior that directly violates fundamental EU values and principles, even given its economic dependence on the EU. This will be done through an evaluation of EU capacity to impose sanctions on its member states, the competency of economic sanctions in addressing illiberal regimes, and Orbán’s potential reasons for an illiberal turn. In the final section, the paper analyses EU approaches to economic sanctions policy and comments on the steps taken so far regarding potential economic sanctions on Hungary.
Magnetar Activity via the Density-Shear Instability in Hall-MHD

description: We investigate the density-shear instability in Hall-MHD via numerical simulation of the full non-linear problem, in the context of magnetar activity. We confirm the development of the instability of a plane-parallel magnetic field with an appropriate intensity and electron density profile, in accordance with analytic theory. We find that the instability also appears for a monotonically decreasing electron number density and magnetic field, a plane-parallel analogue of an azimuthal or meridional magnetic field in the crust of a magnetar. The growth rate of the instability depends on the Hall properties of the field (magnetic field intensity, electron number density and the corresponding scale-heights), while being insensitive to weak resistivity. Since the Hall effect is the driving process for the evolution of the crustal magnetic field of magnetars, we argue that this instability is critical for systems containing strong meridional or azimuthal fields. We find that this process mediates the formation of localised structures with much stronger magnetic field than the average, which can lead to magnetar activity and accelerate the dissipation of the field and consequently the production of Ohmic heating. Assuming a $5\times10^{14}$G magnetic field at the base of crust, we anticipate that magnetic field as strong as $10^{15}$G will easily develop in regions of typical size of a few $10^{2}$ meters, containing magnetic energy of $10^{43}$erg, sufficient to power magnetar bursts. These active regions are more likely to appear in the magnetic equator where the tangential magnetic field is stronger.

description: In Study 1a, cueing the opportunity cost will potentiate the relationship between connectedness to the future self, and choosing not to spend money: the relationship between caring about the future outcomes (as measured by the average of the two connectedness to the future self items) and choosing to save (as opposed to purchase) will only be present when participants are reminded of the opportunity costs of purchasing. This reflects the following claim from the paper's abstract: “[C]ues that highlight opportunity costs reduce spending primarily when people …are more connected to their future selves.” The claim is tested by assessing the significance of the difference between two correlation coefficients using a z-test: correlation between an index of participants’ measured connection to future self and a dichotomous choice to spend or not spend money when opportunity cost is highlighted (biserial correlation r(43) = 0.41), versus the correlation between the connectedness measure and the dichotomous choice when opportunity cost is not highlighted (biserial correlation (r(45) = 0.04). This yielded a significant difference between correlation coefficients, z = 2.14, p < 0.05.

description: The title of the exhibition mounted at the Museo Regionale di Scienze Naturali of Turin, “Times are changing: current knowledge and future scenarios of climate change,” is explicative of the authors’ (Luca Mercalli and Claudio Cassardo) main purpose: making the visitor aware both of climate change already occurring - including its effects at global and local levels - and of possible future scenarios. If Arctic and Antarctic, alpine, coastal and rural landscapes show the first signs of climate change (primarily related to global warming) already today, at the end of the century these landscapes will have changed even more dramatically. In order to minimize damages a prompt turnabout and avoidance of the so-called “Titanic syndrome,” i.e. denying a problem which is now evident, are needed.

description: Laevens et al. recently discovered Triangulum II, a satellite of the Milky Way. Its Galactocentric distance is 36 kpc, and its luminosity is only 450 L_sun. Using Keck/DEIMOS, we measured the radial velocities of six member stars within 1.2' of the center of Triangulum II, and we found a velocity dispersion of sigma_v = 5.1 -1.4 +4.0 km/s. We also measured the metallicities of three stars and found a range of 0.8 dex in [Fe/H]. The velocity and metallicity dispersions identify Triangulum II as a dark matter-dominated galaxy. The galaxy is moving very quickly toward the Galactic center (v_GSR = -262 km/s). Although it might be in the process of being tidally disrupted as it approaches pericenter, there is no strong evidence for disruption in our data set. The ellipticity is low, and the mean velocity, = -382.1 +/- 2.9 km/s, rules out an association with the Triangulum-Andromeda substructure or the Pan-Andromeda Archaeological Survey (PAndAS) stellar stream. If Triangulum II is in dynamical equilibrium, then it would have a mass-to-light ratio of 3600 -2100 +3500 M_sun/L_sun, the highest of any non-disrupting galaxy (those for which dynamical mass estimates are reliable). The density within the 3-D half-light radius would be 4.8 -3.5 +8.1 M_sun/pc^3, even higher than Segue 1. Hence, Triangulum II is an excellent candidate for the indirect detection of dark matter annihilation.

description: Previous studies have shown that environment and health can influence drug use trajectories and the effects of substance use disorder (SUD) treatments. We hypothesized that trajectories of drug use-related problems, based on changes in DSM-5 symptoms, would vary by type(s) of drugs used, health factors, and neighborhood characteristics. We assessed mental and physical health, stress, social instability, neighborhood characteristics (disorderliness and home value), and DSM-5 symptom counts at two study visits, 12 months apart, in a community sample (baseline N = 735) in Baltimore, MD. Three prominent categories of drug-use trajectory were identified with K-means cluster analysis of symptom counts: Persistent (4 or more symptoms at both visits or at Visit 2), Improved (decrease from 4 or more symptoms at Visit 1 to 3 or fewer symptoms at Visit 2), and Low-Stable (3 or fewer symptoms at both visits). Baseline health and neighborhood measures were tested as predictors of trajectory in mediation and moderation models. Among people with current opioid- and/or stimulant-use, odds of an Improved trajectory were (1) decreased with neighborhood disorder and social instability, or (2) increased with home value and social instability. Odds of a Low-Stable trajectory were decreased by social instability and stress but increased in those who were older or self-identified as white. Trajectories of drug use-related problems are influenced by sociodemographic variables, neighborhood factors, and health. Assessing DSM-5 symptom counts as an outcome measure may be valuable in monitoring or predicting long-term trajectories and treatment effectiveness.
Clearing A Path: Generating and Validating a Construct Definition of and Measures for Teacher Working Conditions
Creators: name: Merrill, Rebecca
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Teacher working conditions (TWCs) have been linked to teacher retention and student learning. These connections make TWCs important to understand. However, the literature on TWCs lacks cohesiveness, with widely varying definitions, conceptualizations, and measures of TWCs. Contributing to this lack of cohesion is that there is no accepted construct definition delineating and defining what TWCs are and how to measure them. This dissertation fills a gap by developing a construct definition of TWCs through a two-step process. First, I developed a draft construct definition of TWCs through a systematic review and narrative synthesis of the literature, with a focus on defining TWCs narratively and organizing its components into a typology.       	Second, I employed the Delphi method, new to education policy research, to revise and validate the TWCs construct definition. Using this method, I administered two rounds of iterative questionnaires to teachers in North Carolina to obtain their feedback, suggestions, and input on the draft construct definition. Additionally, to address an overreliance on subjective measures in the literature, the questionnaire was designed to generate observable measures of TWCs. Questionnaire results informed revision to the construct definition, resulting in a definition and typology of TWCs that is research-based and teacher-vetted. This dissertation contributes a narrative definition, typology, and observable measures that clear a path for cohesive        study of TWCs. Further, I identify components within the typology that teachers indicate are important and find that a widely used survey of TWCs does not address three of these important components. These findings have application in policy, research, leadership preparation, and for practitioners.

description: Due to legal reforms, equal parenting time (EPT) laws in Spain now apply to approximately 40% of all divorces, with likely implications for family outcomes and teenagers’ risky behavior. Consistent with theories of bargaining power within marriage, we find that EPT laws decrease contentious and wife-initiated divorces and increase the employment of mothers relative to fathers. An analysis of drug use and family relationships, among 165,000 teenagers, further shows that EPT laws significantly decrease risky behavior by teenagers, especially boys, who claim to have better relationships with their father, although more unclear norms for behavior. These results have some international implications, such as for the United States, where more than half of the states are considering whether to adopt EPT laws.

description: Similar to electromagnetism, described by the Maxwell equations, the physics of magnetoelectric (ME) phenomena deals with the fundamental problem of the relationship between electric and magnetic fields. Despite a formal resemblance between the two notions, they concern effects of different natures. In general, ME coupling effects manifest in numerous macroscopic phenomena in solids with space and time symmetry breakings. Recently it was shown that the near fields in the proximity of a small ferrite particle with magnetic dipolar mode (MDM) oscillations have the space and time symmetry breakings and topological properties of these fields are different from topological properties of the free space electromagnetic (EM) fields. Such MDM originated fields, called magnetoelectric (ME) fields, carry both spin and orbital angular momentums. They are characterized by power flow vortices and non zero helicity. In this paper, we report on observation of the topological ME effects in far field microwave radiation based on a small microwave antenna with a MDM ferrite resonator. We show that the microwave far-field radiation can be manifested with a torsion structure where an angle between the electric and magnetic field vectors varies. We discuss the question on observation of the regions of localized ME energy in far field microwave radiation.

description: Let X be a smooth projective surface of irregularity 0. The Hilbert scheme of n points on X parameterizes zero-dimensional subschemes of X of length n. In this paper, we discuss general methods for studying the cone of ample divisors on the Hilbert scheme. We then use these techniques to compute the cone of ample divisors on the Hilbert scheme for several surfaces where the cone was previously unknown. Our examples include families of surfaces of general type and del Pezzo surfaces of degree 1. The methods rely on Bridgeland stability and the Positivity Lemma of Bayer and Macri.
description: Corrected an error in section 5: the action of the Weyl group on the extremal rays of Nef(X) is not transitive, and instead has two orbits (see Proposition 5.2). All the results from the section still hold after small modifications to the proofs
Reducing Barriers and Enhancing Linkages to Alcoholics Anonymous 12-step Groups for Alcohol Dependent Students on College Campuses: A Program Evaluation
Creators: name: Mitchell, Brittany G
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Aim: This project was completed due to a lack of research and low likelihood of attendance to Alcoholics Anonymous (AA) 12-step groups by college students suffering from Alcohol Use Disorder (AUD). This program evaluation was completed to provide university students and campus wellness staff the opportunity to evaluate a newly created Frequently Asked Questions (FAQs) video about AA and an AA attendance plan for consideration of future use in psychiatric practice.      Background: Current evidence reveals a need for college aged interventions for AUD. College students may be referred to AA by campus staff but have difficulties bridging the gap between recommendation and attendance (American Addictions Centers, 2017). Students seeking mental healthcare prefer brief computerized interventions which have shown to promote treatment initiation in young adults (Buscemi, Murphy, Martens, McDevitt-Murphy, Dennhardty, & Skidmore, 2010; Pedersen & Paves, 2014).      Methods: This program was delivered via e-mail distribution to college students and counseling center staff and in person sessions with nursing student advisory council groups. All data collected were obtained on a volunteer basis by electronic anonymous questionnaire.       Results: Outcomes were measured in three groups (nursing student advisory council, campus wellness staff, and general university students) by qualitative and quantitative data from post-implementation survey responses. In all three groups, 70% or more of the participants found the program improved their knowledge, was interesting, and useful. Recommendations from participants for program improvement included informative aspects and visual enhancements of the FAQs video.       Conclusion: These findings support the potential benefits of revising the “Guide me to AA—FAQs video and making it available for use by psychiatric professionals to educate and support students in need of support for AUD and whom could benefit from AA attendance.

description: Buprenorphine (BUP) effectively suppresses non-prescription opioid use and increases treatment retention in opioid use disorder (OUD). However, short prescription length may interfere with treatment retention and recovery. We wanted to examine whether the outcomes of BUP treatment differ in high (HPL up to 4 wk) and low-prescription (LPL 1–2 wk) length groups. We compared time to treatment discontinuation (TD), non-prescription opioid-positive urine screen, buprenorphine-negative urine screen, and self-reported non-prescription opioid use between two different cohorts of LPL (case record: June 2018 to August 2019; n = 105; observation endpoint: 31 October 2019) and HPL groups (case record: June 2020 to Aug 2021; n = 133; observation endpoint: 31 October 2021). We used Kaplan-Meier survival analysis and log-rank tests for between-group comparisons. We used Cox regression analysis to adjust for age, opioid potency, comorbidities, family income, and marital status. Subjects’ age and buprenorphine dose were significantly lower, and the percentage of high-potency opioid users was significantly higher in the LPL group. In the unadjusted survival analysis, the median time to BUP discontinuation in the HPL was longer than that of the LPL [LPL= 22.4 ± 4.3 wk; HPL = 33.1 ± 8.5 wk; χ2(1)= 5.7; p=.02]. The survival distributions of other outcomes did not differ between groups. When adjusted for covariates, neither the prescription length nor other covariates independently predicted any treatment outcome. Higher prescription length might be associated with longer treatment retention. We provide preliminary evidence to support greater flexibility in BUP treatment, enhancing its scalability and attractiveness.

description: Η χειροσφαίριση είναι ένα ομαδικό δυναμικό άθλημα με υψηλές επιβαρύνσεις, που οδηγεί συχνά τους αθλητές σε κακώσεις. Σκοπός της μελέτης ήταν η καταγραφή των κακώσεων και της ιατρικής φροντίδας, και η ανεύρεση κατάλληλων μέτρων πρόληψης και αντιμετώπισης σε χειροσφαιριστές. Το υλικό της μελέτης αποτέλεσαν 216 παίκτες 18 ομάδων Α1, Α2-Β εθνικής κατηγορίας, και τοπικού πρωταθλήματος. Ο κάθε αθλητής, συμπλήρωσε ερωτηματολόγιο σχετικό με τις κακώσεις που είχε υποστεί τους προηγούμενους 24 μήνες. Τα αποτελέσματα της έρευνας έδειξαν μια υψηλή συχνότητα και βαρύτητα κακώσεις (42,6%) και (64,1%) αντίστοιχα. Tο υψηλότερο ποσοστό παρουσίασαν oι κακώσεις συνδέσμων (18,5%) και τα διαστρέμματα (18,5%) των κάτω άκρων. Οι κακώσεις προκλήθηκαν κατά κύρια αιτία από συγκρούσεις χειροσφαιριστών με αντίπαλους παίκτες (46,7%). Ιατρική διάγνωση των κακώσεων έγινε στο (82,6%). Συμπερασματικά λοιπόν διαπιστώνεται, ότι η χειροσφαίριση ανήκει στα αθλήματα υψηλού κινδύνου, ενώ τα μέτρα πρόληψης και αντιμετώπισης θα πρέπει να περιλαμβάνουν στοιχεία που αφορούν προπονητές, παίκτες, διαιτητές, φυσιοθεραπευτές και ιατρούς
description: Team handball is a dynamic team sport with a high risk factor which leads to frequent injuries of the players. The aims of the study was firstly the recording of injuries and the medical care administered, and secondly to find suitable preventative measurements and treatment of injuries incurred by male handball players. The sample which was study comprised of 216 players from 18 teams; the A1 and A2-B national division, and local championship. Each athlete, complete a questionnaire relating to injuries incurred during the previous 24 months. The results showed that the frequency at which injuries occurred was high and the injuries themselves were of a serious nature, (42.6%) and (64.1%) respectively. The highest percentage of injuries was attributed to connective tissue (18.5%) and sprains of the lower limbs (18.5%). The main reasons which caused these injuries was collision with opponent players (46.7%). (82.6%) of the injuries were medically diagnosed. In conclusion the study reveals that team handball belongs to the group of sports categorised as high-risk injury in regard to the frequency and severity of injuries incurred. Furthermore preventative measures and treatment should include factors which also concern trainers, players, referees, physiotherapists and doctors of sport medicine
