description: The emergence of controlled, two-dimensional moir e´ materials 1–6 has uncovered a new platform for investigating topological physics 7–9. Twisted double bilayer graphene (TDBG) has been predicted to host a topologically non-trivial gapped phase with Chern number equal to two at charge neutrality, when half the ﬂat bands are ﬁlled 8,9. However, it can be difﬁcult to diagnose topological states using a single measurement because it is ideal to probe the bulk and edge properties at the same time. Here, we report a combination of chemical potential measurements, transport measurements, and theoretical calculations that show that twisted double bilayer graphene can host metallic edge transport while si- multaneously being insulating in the bulk. A Landauer-B¨ uttiker analysis of measurements on multi-terminal samples allows us to quantitatively assess edge state scattering. We in- terpret these results as signatures of the predicted topological phase at charge neutrality.

description: The structural and thermal properties of bulk Td-WTe2 have been studied by using first-principles calculations. We find that the lattice thermal conductivity of WTe2 is anisotropic, with the highest value along a-axis and lowest one along the c-axis at 300 K. Our calculated size dependent thermal conductivity shows that nanostructuring of WTe2 can possibly further decrease the lattice thermal conductivity. Such extremely low thermal conductivity, even much lower than WSe2, makes WTe2 attractive for use as thermal-insulation material for thermoelectric devices.

 The second species, A. longiradiatum, is known only from the type collection from the Kasanga River in the Democratic Republic of the Congo (DRC). Unfortunately, Cannon (1978) confused this species with another, superficially similar plant from the border region between Zambia and Tanzania, east of Lake Tanganyika. Both these plants have long, slender rays and pedicels which may account for Cannon’s assertion that they were conspecific. Upon closer examination, it is evident that A. longiradiatum has sheathing leaf bases and linear ultimate leaf segments, while the Zambia-Tanzania plant has non-sheathing leaf bases and filiform ultimate leaf segments (Fig. 1).
 The sheathing leaf bases and narrowly triangular involucral bracts of A. longiradiatum superficially resemble those of Diplolophium zambesianum Hiern (1877: 18). Closer investigation, however, shows the presence of calyx teeth, as well as a virtually glabrous ovary, thus eliminating the possibility that it could be a species of Diplolophium Turcz. (1847: 173). Cannon (1978), apparently for convenience alone, applied a broad concept of Physotrichia longiradiatum H.Wolff to accommodate the second element where it occurs in the border region of Tanzania and Zambia. We find no reason at this stage to deviate from Wolff’s (1912) original placement of this species in Physotrichia because the fruits are not hairy, as is typical for Diplolophium.

description: Plasmonic materials, and their ability to enable strong concentration of optical ﬁelds, have offered a tantalizing foun- dation for the demonstration of sub-diffraction-limit photonic devices. However, practical and scalable plasmonic optoelectronics for real world applications remain elusive. In this work, we present an infrared photodetector leverag- ing a device architecture consisting of a “designer” epitaxial plasmonic metal integrated with a quantum-engineered detector structure, all in a mature III-V semiconductor material system. Incident light is coupled into surface plasmon- polariton modes at the detector/designer metal interface, and the strong conﬁnement of these modes allows for a sub-diffractive (∼λ0/33) detector absorber layer thickness, effectively decoupling the detector’s absorption efﬁciency and dark current. We demonstrate high-performance detectors operating at non-cryogenic temperatures (T= 195 K), without sacriﬁcing external quantum efﬁciency, and superior to well-established and commercially available detectors. This work provides a practical and scalable plasmonic optoelectronic device architecture with real world mid-infrared applications.

description: We present the effect of a hydrodynamical wind on the structure and the surface temperature of a vertically self-gravitating magnetized ADAFs using self-similar solutions. Also a model for an axisymmetric, steady-state, vertically self-gravitating hot accretion flow threaded by a toroidal magnetic field has been formulated. The model is based on $α-$prescription for turbulence viscosity. It is found that the thickness and radial velocity of the disc are reduced significantly as wind gets stronger. In particular, the solutions indicated that the wind and advection have the same effects on the structure of the disc. We also find that in the optically thin ADAF becomes hotter by including the wind parameter and the self-gravity parameter.

description: Cardiac fibrosis is a pathological process characterized by excessive tissue deposition, matrix remodeling, and tissue stiffening, which eventually leads to organ failure. On a cellular level, the development of fibrosis is associated with the activation of cardiac fibroblasts into myofibroblasts, a highly contractile and secretory phenotype. Myofibroblasts are commonly identified in vitro by the de novo assembly of alpha‑smooth muscle actin stress fibers; however, there are few methods to automate stress fiber identification, which can lead to subjectivity and tedium in the process. To address this limitation, we present a computer vision model to classify and segment cells containing alpha‑smooth muscle actin stress fibers into 2 classes (α‑SMA SF + and α‑SMA SF‑), with a high degree of accuracy (cell accuracy: 77%, F1 score 0.79). The model combines standard image processing methods with deep learning techniques to achieve semantic segmentation of the different cell phenotypes. We apply this model to cardiac fibroblasts cultured on hyaluronic acid‑based hydrogels of various moduli to induce alpha‑smooth muscle actin stress fiber formation. The model successfully predicts the same trends in stress fiber identification as obtained with a manual analysis. Taken together, this work demonstrates a process to automate stress fiber identification in in vitro fibrotic models, thereby increasing reproducibility in fibroblast phenotypic characterization.

description: We present a search for prompt radio emission associated with the short-duration gamma-ray burst (GRB) 150424A using the Murchison Widefield Array (MWA) at frequencies from 80-133 MHz. Our observations span delays of 23 s-30 min after the GRB, corresponding to dispersion measures of 100-7700 pc/cm^3. We see no excess flux in images with timescales of 4 s, 2 min, or 30 min, and set a 3 sigma flux density limit of 3.0 Jy at 132 MHz on the shortest timescales: some of the most stringent limits to date on prompt radio emission from any type of GRB. We use these limits to constrain a number of proposed models for coherent emission from short-duration GRBs, although we show that our limits are not particularly constraining for fast radio bursts because of reduced sensitivity for this pointing. Finally, we discuss the prospects for using the MWA to search for prompt radio emission from gravitational wave transients and find that while the flux density and luminosity limits are likely to be very constraining, the latency of the gravitational wave alert may limit the robustness of any conclusions.

Interned or imprisoned?: the successes and failures of international law in the treatment of American internees in Switzerland, 1943-45
Creators: name: Mears, Dwight S.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: During World War II, over 100,000 soldiers of various nationalities sought refuge in neutral Switzerland, including over 1,500 American airmen from damaged U.S. bombers. As a result of the U.S. violations of Swiss neutrality and other external factors, the Swiss government was unwilling to apply the 1929 Geneva Convention prisoner of war protections to the U.S. airmen when they were punished for attempting escape. The politicization of internment procedures resulted in a diplomatic stalemate in which the ambivalence of Swiss officials prolonged mistreatment of U.S. airmen in violation of emerging customary international law. I believe that answering the question of how international law functioned in the scenario of Swiss internment will demonstrate both the cultural importance of Swiss adherence to international law, as well as the process by which states frequently interpret ambiguous international law to their advantage.

description: The magnetic tunnel junction is a cornerstone of spintronic devices and circuits, providing the main way to convert between magnetic and electrical information. In state-of-the-art magnetic tunnel junctions, magnesium oxide is used as the tunnel barrier between magnetic electrodes, providing a uniquely large tunnel magnetoresistance at room temperature. However, the wide bandgap and band alignment of magnesium oxide-iron systems increases the resistance-area product and causes challenges of device-to-device variability and tunnel barrier degradation under high current. Here, we study using first principles narrower-bandgap scandium nitride tunneling properties and transport in magnetic tunnel junctions in comparison to magnesium oxide. These simulations demonstrate a high tunnel magnetoresistance in Fe/ScN/Fe MTJs via Δ1 and Δ2′ symmetry filtering with low wavefunction decay rates, allowing a low resistance-area product. The results show that scandium nitride could be a new tunnel barrier material for magnetic tunnel junction devices to overcome variability and current-injection challenges.
Non-Markovian Effects in the Spin Transfer Dynamics in Diluted Magnetic Semiconductors due to Excitation in Proximity to the Band Edge

description: The non-Markovian effects in the spin dynamics in diluted magnetic semiconductors found in quantum kinetic calculations can be reproduced very well by a much simpler effective single electron theory, if a finite memory is accounted for. The resulting integro-differential equation can be solved by a differential transform method, yielding the Taylor series of the solution. From the comparison of both theories it can be concluded that the non-Markovian effects are due to the spectral proximity of the excited electrons to the band edge.
Reinvigorating Canadian planning practice: A practitioner's view

Subjects: subject: Planners--Canada

description: The practice of planning continues to face criticism for its lack of relevance and its unwillingness to commit to challenging new imperatives. Such criticism is frequently justified. But planning is more complex than many critics realize or are willing to acknowledge. What are the requirements for a re-invigorated profession? What is needed to re-instil a commitment to the roots of the profession? This article examples those issues, and attempts to place the practice of planning within its organizational and societal context. The role of power, organizational structural requirements and ethics are explored. Suggested roles for new alliances are examined, including the need to more firmly link practice and teaching - for their mutual benefit. A professional code of ethics is proposed to assist in the development of a re-commitment to the profession.
description: L'urbanisme continue à susciter des critiques à cause de son peu de pertinence et son manque de volonté à relever de nouveaux défis. Ces critiques sont souvent justifiées. Par contre, l'urbanisme est beaucoup plus complexe que certains critiques le réalisent ou qu'ils veulent le croire. De quoi a-t-on besoin pour revigorer la profession et pour que les urbaniestes s'engagent davantage? Cet article porte sur ces enjeux et tente de situer l'urbanisme dans son contexte organisationnel et social. L'auteur examine le rôle joué par le pouvoir, les contraintes associées aux structures organisationnelles de même que des questions éthiques. Il suggère de nouvelles alliances, par exemple un lien plus étroit entre la pratique et l'enseignement, lequel serait bénéfique à tous deux. Il propose un code de déontologie, lequel encouragerait un nouvel engagement envers la profession.

The Influence of Selected Technical Parameters on Discus Throwing Performance

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: The purpose of this study was to determine the effects of the technical parameters: throwing phase time, hip-shoulder and shoulder-arm separation, trunk tilt, and throwing-arm elevation on discus throwing performance. Videographic data of male and female discus throwers' competitive performances were captured during major meets. Real-life, three-dimensional coordinates of 21 body landmarks and the discus were obtained for 283 trials using direct linear transformation. The technical parameters were reduced at six critical instants during the throwing procedure. Canonical correlation and hierarchical stepwise multiple regression analyses were performed to determine the relative influence of linear combinations of the technical parameters on release characteristics and performance. Specific techniques associated with linear combinations of certain technical parameters were identified for males and females separately. Vertical release velocity was identified as the principal determinant of the difference in performance between athletes. Suggestions for increasing vertical release velocity using effective and efficient technique were made.

description: We show explicitly, by using astrophysical data plus reasonable assumptions for the bulk viscosity in the cosmic fluid, how the magnitude of this viscosity may be high enough to drive the fluid from its position in the quintessence region at present time $t=0$ across the barrier $w=-1$ into the phantom region in the late universe. The phantom barrier is accordingly not a sharp mathematical divide, but rather a fuzzy concept. We also calculate the limiting forms of various thermodynamical quantities, including the rate of entropy production, for a dark energy fluid near the future Big Rip singularity.

Für die Feuerwehr bleibt bei Waldbränden letztlich nur ein Zeitfenster von 30 Minuten von der Entzündung bis zum Eingriff. Danach wird die Gefahr eines unkontrollierbaren Waldbrandes sehr groß. „Letztlich werden Waldbrände bekämpft, bevor sie ausbrechen: durch professionelles Bewirtschaften und Anlegen von Feuerwehr-Wegen.

description: Studies of MHD turbulence often investigate the Fourier power spectrum to provide information on the nature of the turbulence cascade. However, the Fourier power spectrum only contains the Fourier amplitudes and rejects all information regarding the Fourier phases. Here we investigate the utility of two statistical diagnostics for recovering information on Fourier phases in ISM density data: the averaged amplitudes of the bispectrum and the phase coherence index (PCI), a new phase technique for the ISM. We create 3D density and 2D column density maps using a set of simulations of isothermal ideal MHD turbulence with a wide range of sonic and Alfvénic Mach numbers. We find that the bispectrum averaged along different angles with respect to either the $k_1$ or $k_2$ axis is primarily sensitive to the sonic Mach number while averaging the bispectral amplitudes over different annuli is sensitive to both the sonic and Alfvénic Mach numbers. The PCI of density suggests that the most correlated phases occur in supersonic sub-Alfvénic turbulence and also near the numerical dissipation regime. This suggests that non-linear interactions with correlated phases are strongest in shock dominated regions, in agreement with findings from the solar wind. Additionally, our results are particularly encouraging as they suggests the phase information contained in the bispectrum and PCI can be used to find parameters of turbulence in column density maps.

description: We study the instability of charged anti-de Sitter black holes in four or higher-dimension under fragmentation. The instability of fragmentation breaks the black hole into two black holes. We have found that the region near extremal or massive black holes become unstable under fragmentation. These regions depend not only on the mass and charge of initial black hole but also those of the fragmented one. The instability in higher-dimension is qualitatively similar to that of four-dimension. The detailed instabilities are numerically investigated.

description: We have observed 6 late-L and T dwarfs with the Karl G. Jansky Very Large Array (VLA) to investigate the presence of highly circularly polarized radio emission, associated with large-scale auroral currents. Previous surveys encompassing ~60 L6 or later targets in this spectral range have yielded only one detection. Our sample includes the previously detected T6.5 dwarf 2MASS 10475385+2124234 as well as 5 new targets selected for the presence of H-alpha emission or optical/infrared photometric variability, which are possible manifestations of auroral activity. We detect 2MASS 10475385+2124234, as well as 4 of the 5 targets in our biased sample, including the strong IR variable SIMP J01365662+0933473 and bright H-alpha emitter 2MASS 12373919+6526148, reinforcing the possibility that activity at these disparate wavelengths is related. The radio emission frequency corresponds to a precise determination of the lower-bound magnetic field strength near the surface of each dwarf and this new sample provides robust constraints on dynamo theory in the low mass brown dwarf regime. Magnetic fields >2.5 kG are confirmed for 5/6 targets. Our results provide tentative evidence that the dynamo operating in this mass regime may be inconsistent with predicted values from a recently proposed model. Further observations at higher radio frequencies are essential for verifying this assertion.

Species diversity patterns at ecotones
Creators: name: Senft, Amanda Ruth

description: This thesis aims to clarify species richness patterns at ecotones, the mechanisms underlying these patterns, and the challenges faced when trying to link diversity patterns to ecotone properties. Species present at ecotones may be characterized as coming from two sources: those that derive from additive blending of species from adjoining communities and those that are from ecotonal specialists. Diversity at ecotones is dependent on multiple factors, including environmental heterogeneity, spatial mass effect, invasive species spread, animal activities, and hybridization. To clarify the importance of these factors, I constructed vegetation transects across field/forest edges which varied in their disturbance regimes and landscape position. I found that, in general, these ecotones did not have higher species richness than the adjacent vegetation, and that the species present were mostly also present on either side of the transition, with very few species unique to the ecotone. The results of this study provide a starting point for linking patterns of diversity with ecotone properties.
Gradient Scan Gibbs Sampler: an efficient algorithm for high-dimensional Gaussian distributions

description: This paper deals with Gibbs samplers that include high dimensional conditional Gaussian distributions. It proposes an efficient algorithm that avoids the high dimensional Gaussian sampling and relies on a random excursion along a small set of directions. The algorithm is proved to converge, i.e. the drawn samples are asymptotically distributed according to the target distribution. Our main motivation is in inverse problems related to general linear observation models and their solution in a hierarchical Bayesian framework implemented through sampling algorithms. It finds direct applications in semi-blind/unsupervised methods as well as in some non-Gaussian methods. The paper provides an illustration focused on the unsupervised estimation for super-resolution methods.

The relationship between blood potassium, blood lactate, and electromyography signals related to fatigue in a progressive cycling exercise test
Creators: name: Tenan, Matthew S.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2009

description: Local muscle fatigue may be related to potassium efflux from the muscle cell and lactate accumulation within the muscle. However, this has not been verified. The primary purpose of this investigation was to determine if there was a relationship between fatigue related changes in median power frequency (MPF) of EMG signals from the vastus lateralis and blood lactate (LAC) or potassium (K) during a progressive cycling test. This was tested in eight trained cyclists and triathletes under normal and glycogen reduced conditions to modify the LAC environment. No significant relationships were found between LAC (p>0.27) or K (p>0.16) in either condition during exercise or recovery. Though both lactate and potassium have been implicated as factors relating to neuromuscular fatigue, neither is significantly related to changes in MPF during or after progressive exercise on a cycle ergometer.
β2-adrenergic receptor modulation of macrophage inflammatory mediator production
Creators: name: Snyder, Ellen Amanda
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: Research has demonstrated that the complex interaction between the nervous system and the immune system plays a critical role in maintaining homeostasis. The nervous system is capable of modulating the immune response via activation of β2-adrenergic receptors (β2-ARs) present on immunocompetent cells. Because macrophages are major mediators of the immune response, several investigators have sought to determine the effect of β2-AR stimulation upon inflammatory mediator production by these cells. Traditionally, scientists have regarded β2-AR activity as anti-inflammatory since stimulation of these receptors inhibits LPS-induced production of inflammatory molecules. However, a thorough review of existing literature reveals several publications suggesting β2-AR activation may actually have pro-inflammatory effects upon macrophage response. Importantly, β2-AR drugs are often used to treat various diseases, including several diseases of inflammatory origin. As a result, recognizing the dual immunomodulatory potential of β2-ARs is necessary to fully understand the inflammatory impact of β2-AR drugs in therapy.

description: Optical access networks connect multiple endpoints to a common network node via shared fibre infrastructure. They will play a vital role to scale up the number of users in quantum key distribution (QKD) networks. However, the presence of power splitters in the commonly used passive network architecture makes successful transmission of weak quantum signals challenging. This is especially true if QKD and data signals are multiplexed in the passive network. The splitter introduces an imbalance between quantum signal and Raman noise, which can prevent the recovery of the quantum signal completely. Here we introduce a method to overcome this limitation and demonstrate coexistence of multi-user QKD and full power data traffic from a gigabit passive optical network (GPON). The dual feeder implementation is compatible with standard GPON architectures and can support up to 128 users, highlighting that quantum protected GPON networks could be commonplace in the future.

Publisher: name: Open Science Framework
Year: 2022

description: This corpus is constituted for comparative purposes. We are studying a corpus of letters and diary entries from American women (c. 1650–1953) (Morin 2018), based on a collection published by Alexander Street Press publishing (Rhind-Tutt et al. 2011). Our goal is to compare this corpus of non-published, non-fictional documents with an equivalent corpus of published fiction. To this end, we went through the Gutenberg project to collect works of fiction written by native anglophone women before 1953.
Bekenstein's generalized second law of thermodynamics: The role of the hoop conjecture

description: Bekenstein's generalized second law (GSL) of thermodynamics asserts that the sum of black-hole entropy, $S_{\text{BH}}=Ac^3/4\hbar G$ (here $A$ is the black-hole surface area), and the ordinary entropy of matter and radiation fields in the black-hole exterior region never decreases. We here re-analyze an intriguing gedanken experiment which was designed by Bekenstein to challenge the GSL. In this historical gedanken experiment an entropy-bearing box is lowered into a charged Reissner-Nordström black hole. For the GSL to work, the resulting increase in the black-hole surface area (entropy) must compensate for the loss of the box's entropy. We show that if the box can be lowered adiabatically all the way down to the black-hole horizon, as previously assumed in the literature, then for near-extremal black holes the resulting increase in black-hole surface-area (due to the assimilation of the box by the black hole) may become too small to compensate for the loss of the box's entropy. In order to resolve this apparent violation of the GSL, we here suggest to use a generalized version of the hoop conjecture. In particular, assuming that a physical system of mass $M$ and electric charge $Q$ forms a black hole if its circumference radius $r_{\text{c}}$ is equal to (or smaller than) the corresponding Reissner-Nordström black-hole radius $r_{\text{RN}}=M+\sqrt{M^2-Q^2}$, we prove that a new (and larger) horizon is already formed before the entropy-bearing box reaches the horizon of the original near-extremal black hole. This result, which seems to have been overlooked in previous analyzes of the composed black-hole-box system, ensures the validity of Bekenstein's GSL in this famous gedanken experiment.

description: We construct the first smooth horizonless supergravity solutions that have two topologically-nontrivial three-cycles supported by flux, and that have the same mass and charges as a non-extremal D1-D5-P black hole. Our configurations are solutions to six-dimensional ungauged supergravity coupled to a tensor multiplet, and uplift to solutions of Type IIB supergravity. The solutions represent multi-center generalizations of the non-BPS solutions of Jejjala, Madden, Ross, and Titchener, which have over-rotating angular momenta. By adding an additional Gibbons-Hawking center, we succeed in lowering one of the two angular momenta below the cosmic censorship bound, and bringing the other very close to this bound. Our results demonstrate that it is possible to construct multi-center horizonless solutions corresponding to non-extremal black holes, and offer the prospect of ultimately establishing that finite-temperature black holes have nontrivial structure at the horizon.

description: We present the results of 938 speckle measures of double stars and suspected double stars drawn mainly from the Hipparcos Catalogue, as well as 208 observations where no companion was noted. One hundred fourteen pairs have been resolved for the first time. The data were obtained during four observing runs in 2014 using the Differential Speckle Survey Instrument (DSSI) at Lowell Observatory's Discovery Channel Telescope. The measurement precision obtained when comparing to ephemeris positions of binaries with very well-known orbits is generally less than 2 mas in separation and 0.5 degrees in position angle. Differential photometry is found to have internal precision of approximately 0.1 magnitudes and to be in very good agreement with Hipparcos measures in cases where the comparison is most relevant. We also estimate the detection limit in the cases where no companion was found. Visual orbital elements are derived for 6 systems.
