description: We present discharge probability studies performed with a single Thick Gas Electron Multiplier (THGEM) irradiated with alpha particles in Ar-CO$_2$ and Ne-CO$_2$ mixtures. We observe a clear dependency of the discharge stability on the noble gas and quencher content pointing to lighter gases being more stable against the development of streamer discharges. A detailed comparison of the measurements with Geant4 simulations allowed us to extract the critical charge value leading to the formation of a spark in a THGEM hole, which is found to be within the range of 3-7$\times10^6$ electrons, depending on the gas mixture. Our experimental findings are compared to previous GEM results. We show that the discharge probability of THGEMs exceeds the one measured with GEMs by orders of magnitude. This can be explained with simple geometrical considerations, where primary ionization is collected by a lower number of holes available in a THGEM structure, reaching higher primary charge densities and thus increasing the probability of a spark occurrence. However, we show that the critical charge limits are similar for both amplification structures.

description: The distributed task allocation problem, as one of the most interesting distributed optimization challenges, has received considerable research attention recently. Previous works mainly focused on the task allocation problem in a population of individuals, where there are no constraints for affording task amounts. The latter condition, however, cannot always be hold. In this paper, we study the task allocation problem with constraints of task allocation in a game-theoretical framework. We assume that each individual can afford different amounts of task and the cost function is convex. To investigate the problem in the framework of population games, we construct a potential game and calculate the fitness function for each individual. We prove that when the Nash equilibrium point in the potential game is in the feasible solutions for the limited task allocation problem, the Nash equilibrium point is the unique globally optimal solution. Otherwise, we also derive analytically the unique globally optimal solution. In addition, in order to confirm our theoretical results, we consider the exponential and quadratic forms of cost function for each agent. Two algorithms with the mentioned representative cost functions are proposed to numerically seek the optimal solution to the limited task problems. We further perform Monte Carlo simulations which provide agreeing results with our analytical calculations.
Evaluation of Industrial Development Efforts

description: One of the difficulties of public/private ventures is that firms and governmental institutions often look at projects from very different perspectives. In this paper we illustrate this problem by evaluating a proposed economic development project in North Carolina from three different points of view: financial analyst, economic development planner, and social cost-benefit analyst. The objective of a financial analysis is to determine the long run profitability of a project. Economic development planners, on the other hand, often view the costs of a project as the incentives used by the government, and the output of a project as increased regional income or employment. A social cost-benefit framework provides a more comprehensive approach for evaluating public investment decisions. A social cost-benefit analysis attempts to measure the value of all inputs and outputs of a project according to society's willingness to pay for them.

description: This paper describes a preliminary study on the comparative linguistic ecology of online spaces (i.e., social media language data) and real-world spaces in Aotearoa New Zealand (i.e., subnational administrative areas). We compare measures of linguistic diversity between these different spaces and discuss how social media users align with real-world populations. The results from the current study suggests that there is potential to use online social media language data to observe spatial and temporal changes in linguistic diversity at subnational geographic areas; however, further work is required to understand how well social media represents real-world behaviour.
Quantum kinetic theory of Jeans instability in non-minimal matter-curvature coupling gravity

description: We present a quantum treatment of the Jeans gravitational instability in the Newtonian limit of the non-minimal matter-curvature coupling gravity model. By relying on Wigner functions, allowing for the representation of quantum states in a classical phase space, we formulate a quantum kinetic treatment of this problem, generalizing the classical kinetic approach [C. Gomes, Eur. Phys. J. C 80, 633 (2020)]. This allows us to study the interplay between non-minimal matter-curvature coupling effects, quantum effects, and kinetic (finite-temperature) effects, on the Jeans criterion. We study in detail special cases of the model (general relativity, f(R) theories, pure non-minimal coupling, etc.) and confront the model with the observed stability of Bok globules.

description: Quantum entanglement is analyzed thoroughly in the case of the ground and lowest states of two-electron axially symmetric quantum dots under a perpendicular magnetic field. The individual-particle and the center-of-mass representations are used to study the entanglement variation at the transition from interacting to noninteracting particle regimes. The mechanism of symmetry breaking due to the interaction, that results in the states with symmetries related to the later representation only, being entangled even at the vanishing interaction, is discussed. The analytical expression for the entanglement measure based on the linear entropy is derived in the limit of noninteracting electrons. It reproduces remarkably well the numerical results for the lowest states with the magnetic quantum number M>2 in the interacting regime. It is found that the entanglement of the ground state is a discontinuous function of the field strength. A method to estimate the entanglement of the ground state, characterized by the quantum number M, with the aid of the magnetic field dependence of the addition energy is proposed.

description: Sequential modelling of high-dimensional data is an important problem that appears in many domains including model-based reinforcement learning and dynamics identification for control. Latent variable models applied to sequential data (i.e., latent dynamics models) have been shown to be a particularly effective probabilistic approach to solve this problem, especially when dealing with images. However, in many application areas (e.g., robotics), information from multiple sensing modalities is available -- existing latent dynamics methods have not yet been extended to effectively make use of such multimodal sequential data. Multimodal sensor streams can be correlated in a useful manner and often contain complementary information across modalities. In this work, we present a self-supervised generative modelling framework to jointly learn a probabilistic latent state representation of multimodal data and the respective dynamics. Using synthetic and real-world datasets from a multimodal robotic planar pushing task, we demonstrate that our approach leads to significant improvements in prediction and representation quality. Furthermore, we compare to the common learning baseline of concatenating each modality in the latent space and show that our principled probabilistic formulation performs better. Finally, despite being fully self-supervised, we demonstrate that our method is nearly as effective as an existing supervised approach that relies on ground truth labels.

Auf der Basis kontrollierter Laborexperimente wird untersucht, wie Entscheidungen mit der Art der Information sowie mit dem Entscheidungskontext variieren. Im ersten Kapitel legt ein Experiment die Schwierigkeit mit hypothetischem Denken bzw. mit dem Lernen aus hypothetischen Ereignissen offen. Im Kapitel Zwei untersucht ein anderes Experiment, wie Informationsverarbeitung die Reaktionen der Investoren auf Ambiguität verändert, denn ein eindeutiges, optimales Lernverhalten gibt es unter Ambiguität nicht. Das letzte Kapitel stellt anhand desselben Experiments die Unabhängigkeit zwischen dem Lernprozess und den Risikopräferenzen in Frage.
description: This dissertation investigates various channels through which information processing affects investment decisions. Controlled laboratory experiments allow for studying how subjects’ decisions vary with the type of information and the decision-context. The experiment in the first chapter discloses the difficulty with contingent reasoning, i.e. learning from hypothetical events. A different experiment in Chapter Two analyzes how information processing changes investors’ reactions to ambiguity—an environment with multiple rational learning rules. Using the same experiment, the last chapter questions the independence between belief updating and risk preferences.
Book Review: Blue Urbanism: Exploring Connections between Cities and Oceans
Creators: name: Martin, Amanda
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Nearly half of the seven billion people on earth live within 60 miles of an ocean. Land-based cities, and their ever-growing populations, rely on the sea for transportation, food, livelihoods, recreation and a place for refuse. This great, untamed resource remains all but invisible in sustainable urbanism discussion and practice. This oversight is the topic of Timothy Beatley’s 2014 book, Blue Urbanism: Exploring Connections between Cities and Oceans. Beatley, currently the Teresa Heinz Professor of Sustainable Communities at the University of Virginia’s School of Architecture, has written extensively on green urbanism, but by his own admission, he had overlooked the topic of oceans until his 2011 essay on blue urbanism in Places. While few of the individual ideas presented in his recent book are truly new, Blue Urbanism provides a compelling case for packaging together policies and behaviors that promote the health of ocean systems into a cohesive philosophy.

description: In the alignment limit of a multi-doublet Higgs sector, one of the Higgs mass eigenstates aligns in field space with the direction of the scalar field vacuum expectation values, and its couplings approach those of the Standard Model (SM) Higgs boson. We consider CP-conserving Two-Higgs-Doublet Models (2HDMs) of Type I and Type II near the alignment limit in which the heavier of the two CP-even Higgs bosons, $H$, is the SM-like state observed with a mass of 125 GeV, and the couplings of $H$ to gauge bosons approach those of the SM. We review the theoretical structure and analyze the phenomenological implications of this particular realization of the alignment limit, where decoupling of the extra states cannot occur given that the lighter CP-even state $h$ must, by definition, have a mass below 125 GeV. For the numerical analysis, we perform scans of the 2HDM parameter space employing the software packages 2HDMC and Lilith, taking into account all relevant pre-LHC constraints, constraints from the measurements of the 125 GeV Higgs signal at the LHC, as well as the most recent limits coming from searches for heavy Higgs-like states. Implications for Run 2 at the LHC, including expectations for observing the other scalar states, are also discussed.

The configurational entropy of colloidal particles in a confined space

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We calculate the configurational entropy of colloidal particles in a confined geometry interacting as hard disks using Monte Carlo integration method. In particular, we consider systems with three kinds of boundary conditions: hard, periodic and spherical. For small to moderate packing fraction $ϕ$ values, we find the entropies per particle for systems with the periodic and spherical boundary conditions tend to reach a same value with the increase of the particle number $N$, while that for the system with the hard boundary conditions still has obvious differences compared to them within the studied $N$ range. Surprisingly, despite the small system sizes, the estimated entropies per particle at infinite system size from extrapolations in the periodic and spherical systems are in reasonable agreement with that calculated using thermodynamic integration method. Besides, as $N$ increases we find the pair correlation function begins to exhibit similar features as that of a large self-assembled system at the same packing fraction. Our findings may contribute to a better understanding of how the configurational entropy changes with the system size and the influence of boundary conditions, and provide insights relevant to engineering particles in confined spaces.

description: What happens when creative people are not financially secure enough to create? When consumers do not have sufficient income to purchase their work? Or when financialization depresses wages, the government no longer supports the arts, and the consumers react against it? Scott Timberg’s great warning is that, under these conditions, we will lose our ability to reflect as individuals and as a culture. We will cease to communicate through human values and instead only communicate through monetary value. Timberg posits this ominous warning through anecdotes and personal encounters with characters ranging from record store clerks to graphic designers as well as architects, authors, and musicians.

Showdown at the New River

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1976

description: We have witnessed the struggle many times before - at Hell's Canyon, Glen Canyon, the Grand Canyon ... and on hundreds of smaller rivers throughout the country. The power companies want another hydropro­ject. Across the state and in the nation's capital, where the fate of the river will ultimately be decided, people who have never seen the New River and, perhaps, never even heard of it before last year, are taking sides on the issue. When the House Rules Committee refused to consider a bill to study the New River for inclusion in the National Scenic Rivers System, ABC commentator Harry Reasoner felt moved to criticize the Committee on national television, even though he admitted to never having heard of the river before the bill was brought up. Why? Because it is an issue with both practical and emotional overtones. To many people, the sight of an unspoiled free-flowing river can never compare to that of a man-made reservoir. And to dam such a river is to spit in the face of Nature - to sever one of her most precious arteries.

description: The purpose of the current study is to investigate whether information about four different tariffs can be delivered in a simpler way. Tariffs that are time differentiated or are based on peak load are often perceived as difficult to interpret by consumers. Sometimes complicated instructions may be delivered as heuristics with the same or even better decision outcomes. We intend to replicate tariff knowledge from a recent study by comparing the original elaborate instruction before presenting four different electricity tariffs with presenting heuristics. They draw on the idea that people may implement simple rules consciously to make good decisions, without having to engage in deriving the optimal response to a tariff, or engage in elaborate thinking. Second, we want to investigate whether different background (e.g., education, age, residence) is related to performance. Third want to investigate whether risk aversion, time discounting and mathematical ability is related to performance. Finally, we want to assess the contribution of people’s environmental attitudes to their performance.
Adult Entertainment Zoning: A Case Study

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1981

description: In a decade when much of government's time and resources have been consumed in the fight against crime, thought about society's views on victimless crimes has been considerable. When citizens are being victimized by violent crimes and when resources are stretched thin, officials are forced to examine the priorities of the criminal justice system. Few would dispute that efforts to ensure the safety of citizens in the streets and their homes should prevail over attempts to keep a consenting adult from viewing obscene material. Yet society, in its fickle and complicated way, creates a paradox for government officials. Protection against both the real physical threat of violence and property crimes and the tenuous spiritual threat of immorality are called for. Resources are probably not great enough, however, to meet either threat, much less both of them. "Interviews with law enforcement officers and public prosecutors across the country...consistently revealed a view that fiscal and political constraints barred an aggressive drive against pornography, which would necessarily be perceived to be at the expense of other, more urgent law enforcement priorities" (Strum, 1977, p. 13). How then, other than to continue to expend already stretched resources, can government control victimless crimes? One area that is currently receiving attention is the use of zoning as an alternative to control the proliferation of the adult entertainment business, which includes adult book stores, adult motion picture theaters, massage parlors, and adult cabarets. In examining the potential of zoning to control those activities, much attention will be directed to the experience of Fayetteville , North Carolina.

description: Kepler-454 (KOI-273) is a relatively bright (V = 11.69 mag), Sun-like starthat hosts a transiting planet candidate in a 10.6 d orbit. From spectroscopy, we estimate the stellar temperature to be 5687 +/- 50 K, its metallicity to be [m/H] = 0.32 +/- 0.08, and the projected rotational velocity to be v sin i <2.4 km s-1. We combine these values with a study of the asteroseismic frequencies from short cadence Kepler data to estimate the stellar mass to be 1.028+0:04-0:03 M_Sun, the radius to be 1.066 +/- 0.012 R_Sun and the age to be 5.25+1:41-1:39 Gyr. We estimate the radius of the 10.6 d planet as 2.37 +/- 0.13 R_Earth. Using 63 radial velocity observations obtained with the HARPS-N spectrograph on the Telescopio Nazionale Galileo and 36 observations made with the HIRES spectrograph at Keck Observatory, we measure the mass of this planet to be 6.8 +/- 1.4M_Earth. We also detect two additional non-transiting companions, a planet with a minimum mass of 4.46 +/- 0.12 M_J in a nearly circular 524 d orbit and a massive companion with a period >10 years and mass >12.1M_J . The twelve exoplanets with radii <2.7 R_Earth and precise mass measurements appear to fall into two populations, with those <1.6 R_Earth following an Earth-like composition curve and larger planets requiring a significant fraction of volatiles. With a density of 2.76 +/- 0.73 g cm-3, Kepler-454b lies near the mass transition between these two populations and requires the presence of volatiles and/or H/He gas.

What Do You Get from Turning on Your Video? Effects of Videoconferencing Affordances on Remote Class Experience During COVID-19

description: The outbreak of COVID-19 forced schools to swiftly transition from in-person classes to online or remote offerings, making educators and learners alike rely on online videoconferencing platforms. Platforms like Zoom offer audio-visual channels of communication and include features that are designed to approximate the classroom experience. However, it is not clear how students' learning experiences are affected by affordances of the videoconferencing platforms or what underlying factors explain the differential effects of these affordances on class experiences of engagement, interaction, and satisfaction. In order to find out, we conducted two online survey studies: Study 1 (N = 176) investigated the effects of three types of videoconferencing affordances (i.e., modality, interactivity, and agency affordances) on class experience during the first two months after the transition to online learning. Results showed that usage of the three kinds of affordances was positively correlated with students' class engagement, interaction, and satisfaction. Perceived anonymity, nonverbal cues, and comfort level were found to be the key mediators. In addition, students' usage of video cameras in class was influenced by their classmates. Study 2 (N = 256) tested the proposed relationships at a later stage of the pandemic and found similar results, thus serving as a constructive replication. This paper focuses on reporting the results of Study 1 since it captures the timely reactions from students when they first went online, and the second study plays a supplementary role in verifying Study 1 and thereby extending its external validity. Together, the two studies provide insights for instructors on how to leverage different videoconferencing affordances to enhance the virtual learning experience. Design implications for digital tools in online education are also discussed.

description: Nowadays, there is considerable interest in metamaterials which realize the electromagnetically induced transparency in a classical system. We consider the frequency shifts of particle moving in metamaterials exhibiting electromagnetically induced transparency effect. The dramatic change of the material dispersion due to the EIT influences the conditions for signal propagation in the medium and has a significant impact on the Doppler effect, possibly leading to the optical control over this phenomenon. The dependence of the Doppler shift to the source frequency and velocity and radiation spectra on external parameters is examined. It was found that for source frequencies fitting transparency window for particular range of source velocities cutoffs appear, i.e. the radiation is not emitted. Our theoretical findings are proved analytically and confirmed by numerical simulations based on finite-difference time-domain method.

We have developed a novel system that utilizes the capacities of generative AI to transform intricate principles in mathematics, physics, and programming into comprehensible metaphors. To further augment the educational experience, these metaphors are subsequently converted into visual form. Our study aims to enhance the learners' understanding of STEM concepts and their learning engagement by using the visual metaphors. We examine the efficacy of our system via a randomized A/B/C test, assessing learning gains and motivation shifts among the learners. Our study demonstrates the potential of applying large language models to educational practice on STEM subjects. The results will shed light on the design of educational system in terms of harnessing AI's potential to empower educational stakeholders.

description: In his seminal paper on complex reflection arrangements, Bessis introduces a Garside structure for the braid group of a well-generated irreducible complex reflection group. Using this Garside structure, he establishes a strong connection between regular elements in the reflection group, and roots of the "full twist" element of the pure braid group. He then suggests that it would be possible to extend the conclusion of this theorem to centralizers of regular elements in well-generated groups. In this paper we give a positive answer to this question and we show moreover that these results hold for an arbitrary reflection group.

description: The automatic content analysis of mass media in the social sciences has become necessary and possible with the raise of social media and computational power. One particularly promising avenue of research concerns the use of opinion mining. We design and implement the POPmine system which is able to collect texts from web-based conventional media (news items in mainstream media sites) and social media (blogs and Twitter) and to process those texts, recognizing topics and political actors, analyzing relevant linguistic units, and generating indicators of both frequency of mention and polarity (positivity/negativity) of mentions to political actors across sources, types of sources, and across time.

Incommensurate many-body localization in the presence of long-range hopping and single-particle mobility edge

description: We study many-body localization (MBL) in the quasiperiodic $t_1$-$t_2$ model, focusing on the role of next-nearest-neighbor (NNN) hopping $t_2$, which introduces a single-particle mobility edge. The calculated phase diagram can be divided into three distinct regimes, depending on the strength of the short-range interaction $U$. For weak interactions ($U\ll t_1$), this model is always nonthermal. For intermediate interactions ($U\sim t_1$), the thermal-MBL phase transition in this model is qualitatively the same as that of the Aubry-Andre (AA) model, which is consistent with existing experimental observations. For strong interactions $(U\gg t_1)$, the NNN hopping produces qualitatively new physics because it breaks down the Hilbert space fragmentation present in the AA model. The NNN hopping is thus irrelevant when the interaction is intermediate but relevant for strong interactions.
