description: In American postsecondary education, the arts are largely taught as single-disciplinary practices---unconnected to each other or to the general undergraduate curriculum. Existing requirements in the arts do not frequently offer students the opportunity to consider interdisciplinary approaches or challenges across art forms, which may be important factors in improving the learning experience for students (Detels, 1999). This research study was conducted in the Arts and Ideas Program at the University of North Carolina, Asheville (UNCA), identified by the Association of American Colleges and Universities (1997) as an exemplary interdisciplinary arts program in the core curriculum. Arts and Ideas (ARTS-310) courses take a theme-based, interdisciplinary approach across visual and performing arts disciplines. This study implemented the Measure of Intellectual Development (MID), interdisciplinary writing assessment, and student focus groups. The MID was administered as a one-group pretest-posttest design, collecting data based on the Perry scheme of intellectual development (1970). Interdisciplinary writing assessment of student final papers was based on source elements designed by Wolfe and Haynes (2003; personal communication, September 9, 2005). Student focus groups were conducted to investigate student attitudes toward interdisciplinary learning and the ARTS-310 course experience. The study's sample exhibited a positive mean change of 0.10 Perry position, with 40 percent of these students exhibiting positive MID gains. The MID profile shift from pretest to posttest indicated a shift on the Perry scale from "early multiplicity" (Position 3) toward "late multiplicity" (Position 4). Qualitative analysis of the MID essays further supported this study's finding that the ARTS-310 course experience had a positive effect on students' intellectual development. The results of interdisciplinary writing assessment were incomplete due to the insufficient content of the final papers. The student focus groups found that students were overwhelmingly positive about the ARTS-310 course experience and its impact. Overall, this study established a model for assessing interdisciplinary courses and programs, observing interrelationships between interdisciplinary learning processes and intellectual development. Interdisciplinary arts general education courses present students with multiple perspectives and connections across the arts, providing an ideal opportunity for student intellectual development and interdisciplinary learning.

description: We study asymptotic inference based on cluster-robust variance estimators for regression models with clustered errors, focusing on the wild cluster bootstrap and the ordinary wild bootstrap. We state conditions under which both asymptotic and bootstrap tests and confidence intervals will be asymptotically valid. These conditions put limits on the rates at which the cluster sizes can increase as the number of clusters tends to infinity. To include power in the analysis, we allow the data to be generated under sequences of local alternatives. Simulation experiments illustrate the theoretical results and show that all methods can work poorly in certain cases.

description: A novel dynamical state has been observed in the dynamics of a perdurbed sine-Gordon system. This resonant state, has been experimentally observed as a singularity in the dc current voltage characteristic of an annular Josephson tunnel junction, excited in the presence of a magnetic field. With this respect, it can be assimilated to self-resonances known as Fiske steps. Differently from these, however, we demonstrate, on the basis of numerical simulations, that its detailed dynamics involves rotating fluxon pairs, a mechanism associated, so far, to self-resonances known as zero-field steps.

description: Arrow’s Impossibility Theorem is commonly understood to invoke a dictatorship that is somehow lurking within our voting arrangements. The theorem has been described as proving that “any constitution that respects transitivity, independence of irrelevant alternatives and unanimity is a dictatorship”. But the theorem is really not about dictatorship. It is more appropriately understood as being about the spoiler problem, about the possibility that the presence of a candidate who cannot win the election himself may, nevertheless, violate the “independence of irrelevant alternatives” by switching the outcome of the election between two other candidates. The theorem becomes that no electoral system is guaranteed to avoid the spoiler problem altogether, regardless of the options and regardless of voter preferences.

description: In this paper we explore the quantum behaviour of a SQUID ring which has a significant Josephson coupling energy. We show that that the eigenfunctions of the Hamiltonian for the ring can be used to create macroscopic quantum superposition states of the ring. We also show that the ring potential may be utilised to squeeze coherent states. With the SQUID ring as a strong contender as a device for manipulating quantum information, such properties may be of great utility in the future. However, as with all candidate systems for quantum technologies, decoherence is a fundamental problem. In this paper we apply an open systems approach to model the effect of coupling a quantum mechanical SQUID ring to a thermal bath. We use this model to demonstrate the manner in which decoherence affects the quantum states of the ring.

Utilitarianism, Voting and the Redistribution of Income

Subjects: subject: Financial Economics

subject: utilitarianism

description: Utilitarianism can be misplaced or ambiguous. As a prescription for individual behaviour, the injunction to seek the greatest good for the greatest number is misplaced because there remains a domain of life where, within the bounds of law and custom, one is free to act as selfishly or as altruistically as one pleases. As a criterion for responsible government, it is ambiguous because there is no universally-recognized perception of the greatest good; people have different perceptions which can only be reconciled by compromise or by voting. The greatest number must be of citizens alive today, but governments may be vicariously concerned about people in other countries or yet to be born, in so far as citizens today have such concerns and are prepared to sacrifice for the benefit of others. The greatest good for the greatest number has no rival as a criterion for government, but it is vague nonetheless. Utilitarian ambiguity is inherited in any attempt to combine the ordinary measure of economic growth with changes in the distribution of income on a common scale.
Synthesis of carbon nanotubes and polymers to increase the performance of polymer blends
Creators: name: Anderson Rutledge, Shavesha Lavette
Publisher: name: American University
Year: 2023

description: Nanotechnology has the potential to meet the need for stronger, lighter polymeric materials. Carbon nanotubes introduced into a suitable polymer matrix can be engineered to produce the desired characteristics. Two polymers were focused on in this research, polycaprolactone (PCL) and polyethylene (PE). Polycaprolactones have an extraordinary blend of properties that generate good physical characteristics and low temperature flexibility. Due to its rubbery properties it has been widely used for improving elasticity. PCL has the tendency to form compatible blends with multiple polymers. PCL was chosen primarily because of its ability to be electrospun into fibers. Polyethylene was chosen because of its use in spaceflight applications such as Mars balloons used to conduct scientific research. NASA is in search of new composite materials that will enhance these spaceflight missions. The approach to produce the polymer matrices reported herein employs a range of chemical methods using bench-top level polymer chemistry and carbon nanotubes. Two techniques were studied to produce the desired polymer blends, i.e., electrospinning and extrusion. These techniques were used to obtain homogenous nanopolymer blends and aligned nanopolymer fibers. The samples were studied by scanning electron microscopy and their tensile properties were measured. The properties of the electrospun fibers were studied and an increase in fiber elasticity was observed as the fiber diameter decreased. The extruded polymers displayed over 60% increase in tensile strength with small amounts of carbon nanotubes incorporated within the polymer matrix.

description: The vortex dynamics in mesoscopic superconducting cylinders with rectangular cross section under an axially applied magnetic field is investigated in the multivortex London regime. The rectangles considered range from a square up to an infinite slab. The flux distribution and total flux carried by a vortex placed in an arbitrary position of the sample is calculated analytically by assuming Clem's solution for the vortex core. The Bean-Livingston energy barrier is also analytically calculated in this framework. A Langevin algorithm simulates the flux penetration and dynamical evolution of the vortices as the external field is slowly cycled. The simulated magnetization process is governed by metastable states. The magnetization curves are hysteretic, with paramagnetic response in part of the downward branch, and present a series of peaks corresponding to the entry or expulsion of a single vortex. For elongated rectangles, the vortices arrange themselves into parallel vortex chains and an additional modulation of the magnetization, corresponding to creation or destruction of a vortex chain, comes out.

description: Motivated by recent experiments in which specific thermal properties of complex many-body systems were successfully reproduced on a commercially available quantum annealer, we examine the extent to which quantum annealing hardware can reliably sample from the thermal state in a specific basis associated with a target quantum Hamiltonian. We address this question by studying the diagonal thermal properties of the canonical one-dimensional transverse-field Ising model on a D-Wave 2000Q quantum annealing processor. We find that the quantum processor fails to produce the correct expectation values predicted by Quantum Monte Carlo. Comparing to master equation simulations, we find that this discrepancy is best explained by how the measurements at finite transverse fields are enacted on the device. Specifically, measurements at finite transverse field require the system to be quenched from the target Hamiltonian to a Hamiltonian with negligible transverse field, and this quench is too slow. The limitations imposed by such hardware make it an unlikely candidate for thermal sampling, and it remains an open question what thermal expectation values can be robustly estimated in general for arbitrary quantum many-body systems.

description: We study a cluster-robust variance estimator (CRVE) for regression models with clustering in two dimensions that was proposed in Cameron, Gelbach, and Miller (2011). We prove that this CRVE is consistent and yields valid inferences under precisely stated assumptions about moments and cluster sizes. We then propose several wild bootstrap procedures and prove that they are asymptotically valid. Simulations suggest that bootstrap inference tends to be much more accurate than inference based on the t distribution, especially when there are few clusters in at least one dimension. An empirical example confirms that bootstrap inferences can differ substantially from conventional ones.

A Code for Stellar Binary Evolution and its Application to the Formation of Helium White Dwarfs

description: We present a numerical code intended for calculating stellar evolution in close binary systems. In doing so, we consider that mass transfer episodes occur when the stellar size overflows the corresponding Roche lobe. In such situation we equate the radius of the star with the equivalent radius of the Roche lobe. This equation is handled implicitly together with those corresponding to the whole structure of the star. We describe in detail the necessary modifications to the standard Henyey technique for treating the mass loss rate implicitly together with thin outer layers integrations. We have applied this code to the calculation of the formation of low mass, helium white dwarfs in low mass close binary systems. We found that the global numerical convergence properties are fairly good. In particular, the onset and end of mass transfer episodes is computed automatically.

description: Today's proliferation of powerful facial recognition systems poses a real threat to personal privacy. As Clearview.ai demonstrated, anyone can canvas the Internet for data and train highly accurate facial recognition models of individuals without their knowledge. We need tools to protect ourselves from potential misuses of unauthorized facial recognition systems. Unfortunately, no practical or effective solutions exist. In this paper, we propose Fawkes, a system that helps individuals inoculate their images against unauthorized facial recognition models. Fawkes achieves this by helping users add imperceptible pixel-level changes (we call them "cloaks") to their own photos before releasing them. When used to train facial recognition models, these "cloaked" images produce functional models that consistently cause normal images of the user to be misidentified. We experimentally demonstrate that Fawkes provides 95+% protection against user recognition regardless of how trackers train their models. Even when clean, uncloaked images are "leaked" to the tracker and used for training, Fawkes can still maintain an 80+% protection success rate. We achieve 100% success in experiments against today's state-of-the-art facial recognition services. Finally, we show that Fawkes is robust against a variety of countermeasures that try to detect or disrupt image cloaks.

Quantum pumping in closed systems, adiabatic transport, and the Kubo formula

Publisher: name: arXiv

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

description: Quantum pumping in closed systems is considered. We explain that the Kubo formula contains all the physically relevant ingredients for the calculation of the pumped charge ($Q$) within the framework of linear response theory. The relation to the common formulations of adiabatic transport and ``geometric magnetism" is clarified. We distinguish between adiabatic and dissipative contributions to $Q$. On the one hand we observe that adiabatic pumping does not have to be quantized. On the other hand we define circumstances in which quantized adiabatic pumping holds as an approximation. The deviation from exact quantization is related to the Thouless conductance. As an application we discuss the following examples: classical dissipative pumping by conductance control, classical adiabatic (non dissipative) pumping by translation, and quantum pumping in the double barrier model. In the latter context we analyze a 3 site lattice Hamiltonian, which represents the simplest pumping device. We remark on the connection with the popular $S$ matrix formalism which has been used to calculate pumping in open systems.

We observe vibrational spectra that correspond to triplet $^TΣ$ and mixed $^{S,T}Σ$ molecular states. We establish scaling laws for the energies of the lowest vibrational states vs principal quantum number and obtain zero-energy singlet and triplet $s$-wave scattering lengths from experimental data and a Fermi model. Line broadening in electric fields reveals the permanent molecular electric-dipole moments; measured values agree well with calculations. We discuss the negative polarity of the dipole moments, which differs from previously reported cases.

description: Topological materials rely on engineering global properties of their bulk energy bands called topological invariants. These invariants, usually defined over the entire Brillouin zone, are related to the existence of protected edge states. However, for an important class of Hamiltonians corresponding to 2D lattices with time-reversal and chiral symmetry (e.g. graphene), the existence of edge states is linked to invariants that are not defined over the full 2D Brillouin zone, but on reduced 1D sub-spaces. Here, we demonstrate a novel scheme based on a combined real- and momentum-space measurement to directly access these 1D topological invariants in lattices of semiconductor microcavities confining exciton-polaritons. We extract these invariants in arrays emulating the physics of regular and critically compressed graphene sucht that Dirac cones have merged. Our scheme provides a direct evidence of the bulk-edge correspondence in these systems, and opens the door to the exploration of more complex topological effects, for example involving disorder and interactions.

description: Inference for estimates of treatment effects with clustered data requires great care when treatment is assigned at the group level. This is true for both pure treatment models and difference-in-differences regressions. Even when the number of clusters is quite large, cluster-robust standard errors can be much too small if the number of treated (or control) clusters is small. Standard errors also tend to be too small when cluster sizes vary a lot, resulting in too many false positives. Bootstrap methods generally perform better than t tests, but they can also yield very misleading inferences in some cases.

description: The electronic structure of single crystals Na$_{0.6}$CoO$_2$, which are closely related to the superconducting Na$_{0.3}$CoO$_2$.$y$H$_2$O ($T_c \sim 5K$), is studied by angle-resolved photoelectron spectroscopy. While the measured Fermi surface is found to be consistent with the prediction of a local density band theory, the energy dispersion is highly renormalized, with an anisotropy along the two principle axes ($Γ$-$K$, $Γ$-$M$). Our ARPES result also indicates that an extended flat band is formed slightly above $E_F$ along $Γ$-$K$. In addition, an unusual band splitting is observed in the vicinity of the Fermi surface along the $Γ$-$M$ direction, which differs from the predicted bilayer splitting.

description: Nanotechnology has the potential to meet the need for stronger, lighter polymeric materials. Carbon nanotubes introduced into a suitable polymer matrix can be engineered to produce the desired characteristics. Two polymers were focused on in this research, polycaprolactone (PCL) and polyethylene (PE). Polycaprolactones have an extraordinary blend of properties that generate good physical characteristics and low temperature flexibility. Due to its rubbery properties it has been widely used for improving elasticity. PCL has the tendency to form compatible blends with multiple polymers. PCL was chosen primarily because of its ability to be electrospun into fibers. Polyethylene was chosen because of its use in spaceflight applications such as Mars balloons used to conduct scientific research. NASA is in search of new composite materials that will enhance these spaceflight missions. The approach to produce the polymer matrices reported herein employs a range of chemical methods using bench-top level polymer chemistry and carbon nanotubes. Two techniques were studied to produce the desired polymer blends, i.e., electrospinning and extrusion. These techniques were used to obtain homogenous nanopolymer blends and aligned nanopolymer fibers. The samples were studied by scanning electron microscopy and their tensile properties were measured. The properties of the electrospun fibers were studied and an increase in fiber elasticity was observed as the fiber diameter decreased. The extruded polymers displayed over 60% increase in tensile strength with small amounts of carbon nanotubes incorporated within the polymer matrix.
Universal properties of hard-core bosons confined on one-dimensional lattices

description: Based on an exact treatment of hard-core bosons confined on one-dimensional lattices, we obtain the large distance behavior of the one-particle density matrix, and show how it determines the occupation of the lowest natural orbital in the thermodynamic limit. We also study the occupation $λ_η$ of the natural orbitals for large-$η$ at low densities. Both quantities show universal behavior independently of the confining potential. Finite-size corrections and the momentum distribution function for finite systems are also analyzed.

description: The charter school movement has been the most prominent and controversial education reform in the United States in the last fifteen years. Advocates believe that by granting more autonomy to charter schools, they are subject to higher accountability standards and could provide better education. Thus the public schools are forced to compete and the deteriorating public school system will be revitalized. Charter school accountability is the centerpiece of charter school reform, which is based on the premise of the "autonomy for accountability" bargain. Although numerous studies have evaluated the education outcomes of charter schools, very few have examined the relationship between charter school autonomy and accountability in a systematic way. This dissertation examines the impact of charter school autonomy on school accountability empirically, through both qualitative and quantitative approaches. Under the current charter schooling system, the operation autonomy enjoyed by charter schools varies based on different charter school laws across states. Further, within the framework of state charter laws, charter school autonomy also differs at site level as specified by individual school charter, which is the ultimate legal document that governs school operation. Thus the qualitative case study explores the effect of different charter designs on school success by comparing the charters of sixteen individual schools; and the quantitative study utilizes panel data in thirteen states to examine the impact of state charter laws on charter school achievement. The findings suggest that fewer entry barriers or more operation autonomy do not necessarily lead to higher charter school performance, while the authorizing agencies' selection of the charter school candidates is more important for school success. The conclusion part further discusses the importance of implementation in policy outcomes.

It will be illustrated by analysis of single particle distributions measured in proton-proton, proton-antiproton and nuclear collisions. We shall demonstrate the particular role played by the nonextensivity parameter q in such analysis as summarizing our knowledge on the fluctuations existed in hadronizing system.

description: Xylocopa (Notoxylocopa) tabaniformis orpifex Smith, 1854
[Syntype: NHMUK; ♂ California, USA]
The populations of this species from the BCP belong to the subspecies currently known as Xylocopa tabaniformis orpifex. However, it is possible that this subspecies should be considered as a separate species. The BBPT collected this species in the Coastal Sage Matorral, Chaparral, Baja California Mountains and Gulf Coast (12 ♂, 3 ♀). This species is present throughout the BCP, except in the Succulent Coastal Matorral (Supplementary material 1), which may be an artifact of limited sampling effort. Voucher specimens are in MABC, and ECOAB. See fig. 152.

description: This paper presents an intertemporal model of growing awareness. It provides a framework for analyzing problems with long time horizons in the presence of growing awareness and awareness of unawareness. The framework generalizes both the standard event-tree framework and the framework from Karni and Vier (2017) of awareness of unawareness. Axioms and a representation are provided along with a recursive formulation of intertemporal utility. This allows for tractable and consistent analysis of intertemporal problems with unawareness.

description: Many complex systems, ranging from migrating cells to animal groups, exhibit stochastic dynamics described by the underdamped Langevin equation. Inferring such an equation of motion from experimental data can provide profound insight into the physical laws governing the system. Here, we derive a principled framework to infer the dynamics of underdamped stochastic systems from realistic experimental trajectories, sampled at discrete times and subject to measurement errors. This framework yields an operational method, Underdamped Langevin Inference (ULI), which performs well on experimental trajectories of single migrating cells and in complex high-dimensional systems, including flocks with Viscek-like alignment interactions. Our method is robust to experimental measurement errors, and includes a self-consistent estimate of the inference error.
