description: The electronic state of WTe2, a candidate of type-II Weyl semimetal, is investigated by using laser-based spin- and angle-resolved photoemission spectroscopy (SARPES). We prepare the pair of WTe2 samples, one with (001) surface and the other with (00-1) surface, by "sandwich method", and measure the band structures of each surface separately. The Fermi arcs are observed on both surfaces. We identify that the Fermi arcs on the two surfaces are both originating from surface states. We further find a surface resonance band, which connects with the Fermi-arc band, forming a Dirac-cone-like band dispersion. Our results indicate that the bulk electron and hole bands are much closer in momentum space than band calculations.

description: The bisector of two nonempty sets P and Q in a metric space is the set of all points with equal distance to P and to Q. A distance k-sector of P and Q, where k is an integer, is a (k-1)-tuple (C_1, C_2, ..., C_{k-1}) such that C_i is the bisector of C_{i-1} and C_{i+1} for every i = 1, 2, ..., k-1, where C_0 = P and C_k = Q. This notion, for the case where P and Q are points in Euclidean plane, was introduced by Asano, Matousek, and Tokuyama, motivated by a question of Murata in VLSI design. They established the existence and uniqueness of the distance trisector in this special case. We prove the existence of a distance k-sector for all k and for every two disjoint, nonempty, closed sets P and Q in Euclidean spaces of any (finite) dimension, or more generally, in proper geodesic spaces (uniqueness remains open). The core of the proof is a new notion of k-gradation for P and Q, whose existence (even in an arbitrary metric space) is proved using the Knaster-Tarski fixed point theorem, by a method introduced by Reem and Reich for a slightly different purpose.

description: The normal state of high-Tc cuprates has been considered one of the essential topics in high-temperature superconductivity research. However, compared to the high magnetic fields study of it, understanding a photoinduced normal state remains elusive. Here, we explore a photoinduced normal state of YBa$_2$Cu$_3$O$_{6.67}$ (YBCO) through a charge density wave (CDW) with time-resolved resonant soft x-ray scattering, as well as a high-magnetic field x-ray scattering. In the non-equilibrium state in which people predict a quenched superconducting state based on the previous optical spectroscopies, we experimentally observed a similar analogy to the competition between superconductivity and CDW shown in the equilibrium state. We further observe that the broken pairing states in the superconducting CuO$_2$ plane via the optical pump lead to nucleation of three-dimensional CDW precursor correlation, revealing that the photoinduced CDW is similar to phenomena shown under magnetic fields. Ultimately, these findings provide a critical clue that the characteristics of the photoinduced normal state show a solid resemblance to those under magnetic fields in equilibrium conditions.

title: Micro Electro Mechanical Systems Integrated Frequency Reconfigurable Antennas for Public Safety Applications
Creators: name: Mopidevi, Hema Swaroop
Publisher: name: Utah State University
Year: 2010

description: This thesis work builds on the concept of reconfiguring the antenna properties (frequency, polarization, radiation pattern) using Radio Frequency (RF) Micro Electro Mechanical Systems (MEMS). This is a part of the overall research performed at the RF Micro/Nano Electro Mechanical Systems (uNeMS) Laboratory at Utah State University, which includes design, microfabrication, test, and characterization of uNeMS integrated cognitive wireless communication systems (Appendix A). In the first step, a compact and broadband Planar Inverted F Antenna (PIFA) is designed with a goal to accommodate reconfigurability at a later stage. Then, a Frequency Reconfigurable Antenna (FRA) is designed using MEMS switches to switch between the Public Safety (PS) bands, 152-162 MHz and 406-512 MHz, while maintaining the integrity of radiation pattern for each band. Finally, robust mechanical designs of the RF MEMS switches accompanied by different analyses have been performed. These analyses are instrumental in obtaining high yield, reliable, robust microfabrication processes including thin film metal deposition and patterning.

Design and expression of an ankyrin-like molecular probe for alpha-neurexin 1 labelling in live neurons
Creators: name: Stranger, Vicente
Publisher: name: University of British Columbia
Year: 2025

description: Neurexins (NRXNs) are a set of cell adhesion proteins that play a key role in the formation of new synaptic connections and pre-synaptic differentiation in the brain. NRXNs also participate in the remodeling of synapses terminals. Impairment of proper neurexin function can lead to psychological and developmental disorders, with recent evidence suggesting that they play a role in Alzheimer’s disease. Understanding the molecular mechanisms underlying neurexins alterations is paramount to shed light on their role in neurodegeneration. Current approaches to study NRXN’s function suffer from several limitations. In this project, we developed a molecular probe selective for α-neurexin 1 to label it in live cells by exploiting a neurotoxin found in the venom of Latrodectus spiders. First, we used a bioinformatics approach to identify the sequence of amino acids within a latrotoxin that binds to α-neurexin 1. This minimal sequence was used to design a peptide scaffold for our molecular probe. Then we generated two distinct expression vectors using molecular biology to express a recombinant sequence for selective probes and isolated them from a bacterial expression system. Finally, we assessed the selectivity and cytotoxicity of our recombinant probes in live cells containing α-NRXN 1. Overall, advancements were made on the development and activity assessment of novel approaches to study neurexins. Chapter 2 proposed a novel recognition sequence of latrotoxins to neurexin that up to date has not been identified. In chapter 3 we created modular expression plasmids enabling purification with metal chromatography to obtain a recombinant probe for neurexin. Finally, we showed that probe lost cytotoxic activity, but selectivity to neurexin still needs to be further assessed.

description: We perform a detailed numerical investigation of the approximate moduli space metric proposed by Diakonov and Petrov [arXiv:0704.3181] for a confining model of dyons. Our findings strongly indicate that only for a small number of dyons at sufficiently low density this metric is positive definite - and, therefore, a valid moduli space metric - throughout a considerable part of configuration space. This poses strong limitations on results obtained by an unrestricted integration over collective coordinates in this model. It also indicates that strong correlations between collective coordinates will be essential for the physical content of a dyon model, which could be exhibited by a suitable simulation algorithm.

description: The abundance of beryllium in the oldest, most metal-poor stars acts as a probe of early star formation and Galactic chemical evolution. We have analyzed high-resolution, high signal-to-noise Keck/HIRES spectra of 24 stars with [Fe/H] from -2.3 to -3.5 in order to determine the history of Be abundances and explore the possibility of a Be plateau. We have determined stellar parameters spectroscopically. Oxygen abundances have been derived from three OH features which occur in the same spectral region. We have supplemented this sample with reanalyzed spectra of 25 stars from previous observations; our total sample ranges in [Fe/H] from -0.5 to -3.5. We find that the relationship between Be and [Fe/H] continues to lower metallicities with a slope of 0.92 +-0.04. Although there is no indication of a plateau with constant Be abundance, the four lowest metallicity stars do show a Be enhancement relative to Fe. A single relationship between Be and [O/H] has a slope of 1.21 +-0.08, but there is also a good fit with two slopes: 1.59 for [O/H] > -1.6 and 0.74 for stars with [O/H] < -1.6. This change in slope could result from a change in the dominant production mechanism for Be. In the era of the formation of the more metal poor stars Be would be formed by acceleration of CNO atoms in the vicinity of SNII and in later times by high-energy cosmic rays bombarding CNO in the ambient interstellar gas. We find an excellent correlation between [Fe/H] and [O/H].

Local breaking of the spin degeneracy in the vortex states of Ising superconductors: Induced antiphase ferromagnetic order
Creators: name: Jiang, Hong-Min

Publisher: name: arXiv
Year: 2022
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: Ising spin-orbital coupling is usually easy to identify in the Ising superconductors via an in-plane critical field enhancement, but we show that the Ising spin-orbital coupling also manifests in the vortex physics for perpendicular magnetic fields. By self-consistently solving the Bogoliubov-de Gennes equations of a model Hamiltonian built on the honeycomb lattice with the Ising spin-orbital coupling pertinent to the transition metal dichalcogenides, we numerically investigate the local breaking of the spin and sublattice degeneracies in the presence of a perpendicular magnetic field. It is revealed that the ferromagnetic orders are induced inside the vortex core region by the Ising spin-orbital coupling. The induced magnetic orders are antiphase in terms of their opposite polarizations inside the two nearest-neighbor vortices with one of the two polarizations coming dominantly from one sublattice sites, implying the local breaking of the spin and sublattice degeneracies. The finite-energy peaks of the local-density-of-states for spin-up and spin-down in-gap states are split and shifted oppositely by the Ising spin-orbital coupling, and the relative shifts of them on sublattices $A$ and $B$ are also of opposite algebraic sign. The calculated results and the proposed scenario may not only serve as experimental signatures for identifying the Ising spin-orbital coupling in the Ising superconductors, but also be prospective in manipulation of electron spins in motion through the orbital effect in the superconducting vortex states.

description: The potential failure in through-silicon vias (TSVs) still poses a challenge in trying to extend the useful life of a 3D integrated circuit (IC). A model is proposed to mitigate the communication problem in 3D integrated circuits caused by the breaks at the TSVs. We provide the details of a low-complexity network that takes advantages of redundant TSVs to make it possible to re-route around breaks and maintain effective communication between layers. Different configurations for the micronetwork are analyzed and discussed. We also present an evaluation of the micronetwork's performance, which turns out to be quite promising, based on several Monte Carlo simulations. Finally, we provide some directions for future research on the subject.

description: The issues raised by the re-examination of the liturgical set found at Morbello (prov. Alessandria / I) can be better understood in the wider framework of the production and circulation of cast bronze vessels in the early medieval Mediterranean and Central Europe areas. New typological proposals, refined dating and thorough distribution analysis prove suitable research tools to provide a renewed survey on early medieval trade among different Western territories: here, new production centres seem to have emerged, while the extent of the contacts with the Eastern Mediterranean appears weaker than traditionally assumed. These results mirror the major economic and political transformations underwent by Western Europe and the Mediterranean basin throughout the 7th and 8th centuries, according to a trend also attested by other categories of archaeological finds.

description: The skeletal remains of an individual were found in 2001 in the vicinity of the Roman open-air museum at »Villa Borg« near Oberleuken-Perl, Saarland. Radiocarbon analysis dated the feature to the 1st century AD. No belongings or grave goods were found. The osteological examination showed that the skeletal remains were those of an adult male. The bones bore no evidence of injury or disease, which meant that it was not possible to determine the cause of death. Whilst the carbon and nitrogen isotope ratios were consistent with the local dietary range in the Roman period, the results of the strontium isotope analysis suggested that the individual had spent his childhood and adolescence elsewhere. The second molar of the left mandible exhibited a defect or cavity which contained a substance resembling filling material. Imaging techniques and material analyses were used to determine whether this was indeed a dental filling and to obtain information about the nature and composition of the material used. Hydroxyapatite, rutile, quartz and goethite were identified as the main components, though there was no evidence of a binder. Since crushed bone and teeth have been widely used for various purposes since Antiquity, it is conceivable that the substance analysed was a »filling«.

title: Transmitter Localization Using Autonomous Robotic Swarms
Creators: name: Adams, Joshua S.
Publisher: name: Utah State University
Year: 2010

description: The purpose of this research is to design a proof of concept system that is capable of locating a hidden radio transmitter and to investigate methods of multi-agent formation control with a specific interest in the effectiveness of these methods on the overall objective of locating this transmitter. A system is proposed and developed in which autonomous agents work together to locate this transmitter and their responsiveness is analyzed while using formations based both on a behavioral system and a system derived from centroidal Voronoi tessellations. Many software adaptations to the existing MASnet program are required, as well as some hardware adaptations, including development of a robust simulation platform that may be used in conjunction with the MASnet system, and exploration of a distributed formation system. While this work does not accomplish the overall goal of the MASnet platform -- to be able to locate and control a diffusion process -- it does further understanding of the way autonomous agents interact with their environment and develop tools that aid future research in the program, as well as introduce exciting new areas to which the platform can be applied.
title: Unraveling Conflicting Interpretations: A Reexamination of the 1916 Report on Social Studies
Creators: name: Jorgensen, C. Gregg
Publisher: name: Utah State University
Year: 2010

description: This study examines the 1916 Report on Social Studies in order to determine how it has been interpreted and regarded over time. The underlying question involved is "Which interpretation, or interpretations, most embodies the intent, goals, and purpose of the 1916 Committee"? Key members of the 1916 committee have been identified for extended research and analysis. One additional individual frequently quoted throughout the Report, John Dewey, has been included in this research on the 1916 committee. The design, format, and content of the 1916 Report on Social Studies was closely examined. This study dissected the three individual reports by time, intent, topic, and authority. The wide variety of interpretations offered by the scholars identified for this study was examined within an organizational framework utilized to discuss and analyze the broad spectrum of interpretations that exist. This examination of the report encompassed the existing theories, the meaning and intent of the 1916 committee, as well as the social and political aspects and impacts of the era. The overarching intent of this study was to make sense of the various scholarly interpretations and offer insights as to whether or not a consensus of opinion among scholars existed. This study explored if, in fact, there was one dominant interpretation, or whether or not different interpretations were possible for the 1916 Report on Social Studies. That is, was there an opportunity for this study to employ a new lens through which to view the 1916 Report on Social Studies?
'Poison-to-paradise development'? : unpacking urban land use politics and the financialization of environmental risk in Brooklyn, New York

description: In a northern section of Greenpoint, Brooklyn, the former site of the NuHart Plastic Manufacturing facility is being remediated and redeveloped into a majority market-rate apartment complex. While residents have waited decades for the city to address their concerns related to the contaminants leaching from the site and their potential health effects, the current clean-up has been met with resident frustration and ambivalence. This thesis explores how the structure of the environmental clean-up at NuHart obscures the underlying ecology of injustice of northern Greenpoint. Through archival data, interviews, and observations of community meetings, I analyze how the State and developers construct and maintain regimes of perceptibility that foreclose more expansive solutions to the problems expressed by Greenpoint residents. Chapter 1 depicts how the slow violence of environmental mismanagement shaped Greenpoint into a sacrifice zone. Today, development follows the contours etched by decades of disinvestment, using toxic sites (like NuHart) as opportunities to advance the interests of the real estate state. Chapter 2 examines how the State and developers use statistical data and maps to collapse and quantify the historical accrual of injustice. The knowledge regimes mobilized at NuHart allow the State and developers to wield environmental science as a tool of the green growth machine. Chapter 3 explores how specific constructions of urgency and latency create hegemonic timescapes at the site that are out of rhythm with the neighborhood. By manipulating time so that in turn both urgency and latency are naturalized when it suited the project, developers left no room for residents to articulate an alternative orientation to the remediation timeline. Ultimately, at the NuHart site the narrow framings of both the local environmental crises—as historical but not ongoing—and the housing crisis—as perpetuated by a lack of supply best remedied by swift, smooth development procedures—produced technocratic, partial solutions. By looking more deeply at the root causes of resident ambivalence and the conflicting ways various pasts, presents, and futures of NuHart were articulated by residents and the State, the co-constructed nature of these crises comes into clearer view.

The Beginning of the Use of Quartz-sericite Schist Whetstones in Silesia in the Light of New Discoveries from La Tène Culture Settlements

description: During excavations at two sites of the La Tène culture in Samborowice, Upper Silesia, stone artefacts made from quartz-sericite schist were found. Deposits of this mineral are located in one place only, a hill massif situated in the vicinity of Jegłowa in Lower Silesia. The discussed finds were discovered within a context of precisely dated artefacts of the La Tène culture, which confirm the beginning of use of quartz-sericite schists as early as the onset of the Middle La Tène period. The finds from Samborowice are evidence for the existence of contacts and an organised exchange network between two local communities of the La Tène culture. This has been difficult to prove until recently on the basis of known archaeological finds.

A nitrogen-rich atmosphere on ancient Mars consistent with isotopic evolution models

description: The ratio of nitrogen isotopes in the Martian atmosphere is a key constraint on the planet's atmospheric evolution. However, enrichment of the heavy isotope expected due to atmospheric loss from sputtering and photochemical processes is greater than measurements. A massive, multi-bar early CO2-dominated atmosphere and recent volcanic outgassing have been proposed to explain this discrepancy, and many previous models have assumed atmospheric nitrogen rapidly reached a steady state where loss to space balanced volcanic outgassing. Here we show using time-dependent models that the abundance and isotopic composition of nitrogen in the Martian atmosphere can be explained by a family of evolutionary scenarios in which the initial partial pressure of nitrogen is sufficiently high that a steady state is not reached and nitrogen levels gradually decline to present-day values over 4 billion years. Our solutions do not require a multi-bar early CO2 atmosphere and are consistent with volcanic outgassing indicated by both geologic mapping and the atmospheric 36Ar/38Ar ratio. Monte Carlo simulations that include these scenarios estimate that the partial pressure of N2 was 60 - 740 mbar (90% confidence, with a median value of 310 mbar) at 3.8 billion years ago when the valley networks formed. We suggest that such a high nitrogen partial pressure could have contributed substantially to warming on early Mars.

description: A thoroughly finished miniature cup, found in a waste pit at Nijmegen-Lent, is a special find because of the character-like signs all around it. Despite the fact that far-reaching southern contacts with the Lower Rhine area existed in the Hallstatt C period (Oss, Wijchen), and although some of the signs match those in early southern European scripts, the early date of the cup (c. 750-675 BC) hampers any sound identification. The enigmatic character of the cup is augmented further by its apparent local origin.

Organische Projektile in Magdalénienstationen der Schweiz

description: Im Gebiet der heutigen Schweiz gibt es 13 Fundstellen des Magdalénien (ca. 21 000-14 400 cal BP), in denen organische Projektile überliefert sind. Da diese Fundgattung großes Potenzial für die zeitliche Gliederung der archäostratigrafischen Einheit hat, wurden die Inventare neu aufgenommen und ausgewertet. Die intensive Besiedlung der Region durch das Spätmagdalénien lässt sich an der weiträumigen Verbreitung von Geschossspitzen mit doppelt abgeschrägter Basis und Widerhakenspitzen nachvollziehen. Im Kesslerloch und in benachbarten Fundstellen gibt es zudem mehrere Geschossspitzen mit einfach abgeschrägter Basis und baguettes demi-rondes, die mit dem späten Mittelmagdalénien korrespondieren. Bestimmte Geschossspitzen und Verzierungen deuten auch eine Nutzung der Station im Badegoulien / Frühmagdalénien und im frühen Mittelmagdalénien an. Dem Kesslerloch kommt als Schlüsselfundstelle des mitteleuropäischen Magdalénien eine besondere Bedeutung zu. Direkte AMS-Datierungen an bestimmten organischen Geräten und eine Neuvorlage des lithischen Inventars sind daher ein Desiderat der Forschung.

description: In der zentralörtlichen Siedlung Olsborg im Großen Plöner See in Schleswig-Holstein wurden aus 50 Bodenproben über 12 000 subfossile Pflanzenreste ausgelesen. Als Kulturpflanzen wurden neben wenigen, zumeist verkohlten Getreidekaryopsen (Gerste, Roggen, Weizen, Hafer) vorwiegend Sammelpflanzen (z. B. Himbeere und Brombeere) angetroffen. Zur räumlichen Differenzierung zeichnet sich ein deutlicher Unterschied in der Verteilung der Pflanzenreste ab. Gängige Sammelpflanzen wie Himbeere und Brombeere können in den vier verglichenen norddeutschen Fundplätzen Quetzin, Olsborg, Starigard / Oldenburg sowie Haithabu nachgewiesen werden. Lediglich Importpflanzen wie Wein und Walnuss kamen erwartungsgemäß nur in Haithabu vor. Ein markantes Alleinstellungsmerkmal der Olsborg ist der überdurchschnittlich hohe Anteil an potenziellen Heilkräutern wie Johanniskraut, Minze und Bilsenkraut.

description: This was a study on the Utah cattle industry which compared five different feeding enterprises. These feeding enterprises included feeding cull cows, finishing beef yearling steers, finishing Holstein yearling steers, backgrounding beef steer calves, and backgrounding Holstein steer calves. The main purpose of this study was to determine which feeding enterprise was the most profitable for Utah cattle producers. Another objective of the study was to determine if LRP insurance lowered the volatility in the returns to these feeding enterprises. In order to answer these two questions of interest, a historical analysis of Utah cattle and feed prices was conducted from 1990 through 2009. Weekly sales data were used, and seasonality and price trends were determined. Next, enterprise budgets were created for each feeding enterprise to establish historical returns. Then, using the historical data as a foundation, a simulation analysis was run to forecast future returns and determine the risk associated with each feeding enterprise. LRP insurance was also added to the model to simulate the effects it had on lowering risk. After completing a simulation analysis and comparing means and standard deviations of the expected returns, portfolio theory was used to put the feeding enterprises into different portfolios to attempt to lower risk. Then stochastic dominance was used to conclude which feeding enterprise was the most preferred for Utah cattle producers. The results of the study depend upon the producer's level of risk. The majority of producers have an ARAC value between -0.0002 and 0.0012. With that knowledge, the results suggested that the majority of Utah cattle producers should finish Holstein yearling steers. If a producer was highly risk seeking, then he or she was better off to feed cull cows. If the producer was highly risk averse, then he or she preferred a portfolio of cull cows and backgrounding both Holstein and beef steers with LRP insurance. The results of the study also indicated that LRP insurance was an effective tool for lowering the variability in expected returns. However, the results suggested that the most preferred option for Utah cattle producers was to feed either cull cows or Holstein yearling steers without LRP insurance.

description: In den letzten Jahren wurde ein Heiligtum in Lienz bekannt, das in der Spätlatènezeit wohl als Stammesheiligtum der im Lienzer Becken beheimateten Laianken diente. Mit dem bellum Noricum gelangte es in einen überregionalen Fokus und unter römischen Einfluss. Der gesamte Hügel wurde mit einer sorgfältig gesetzten und verputzten Mauer umgeben, die den heiligen Bezirk abgrenzte. Aus dieser Zeit stammt ein bisher einzigartiger Komplex an Zinnvotiven, der nahezu das gesamte römische Pantheon abbildet. Diese Figuren, von denen über 500 Fragmente gefunden wurden, können als Ausdruck der Volksfrömmigkeit in einem ruralen paganen Heiligtum nahe dem Municipium Aguntum gelten.

description: The valley-polarized quantum anomalous Hall (VQAH) state, which forwards a strategy for combining valleytronics and spintronics with nontrivial topology, attracts intensive interest in condensed-matter physics. So far, the explored VQAH states have still been limited to magnetic systems. Here, using the low-energy effective model and Floquet theorem, we propose a different mechanism to realize the Floquet VQAH state in nonmagnetic heterobilayers under light irradiation. We then realize this proposal via first-principles calculations in transition metal dichalcogenide heterobilayers, which initially possess the time-reversal invariant valley quantum spin Hall (VQSH) state. By irradiating circularly polarized light, the time-reversal invariant VQSH state can evolve into the VQAH state, behaving as an optically switchable topological spin-valley filter. These findings not only offer a rational scheme to realize the VQAH state without magnetic orders, but also pave a fascinating path for designing topological spintronic and valleytronic devices.

Electrothermal behavior

description: Understanding the behavior of solid armatures has been at the forefront of railgun research in the U.S. for over a decade. Computational models have matured in parallel with experimental techniques, but experiments resulting in good data on armature behavior have not existed until recently. As a result, there has been little correlation between what models predict and how solid armatures actually behave. A recent technique for recovering armatures was used to provide a collection of armatures launched with currents from 848 kA to 1256 kA, at speeds around 300 m/s. The recovered armatures showed a progressive amount of melting and cracking in the throat region. Optical microscopy revealed microstructural changes of the armatures due to heating, as well as characteristics of the observed cracks. State of the art computational models were used to estimate the electromagnetic, thermal, and structural response of the armatures. Historical modeling assumptions were tested to see whether they held true when compared with experimental evidence. Thermal diffusion, temperature-dependent material properties, and heating rate effects must all be used for an accurate comparison. Finite element models accurately predicted the thermal behavior of armatures, with the largest stresses coming from thermal expansion. Crack formation is likely due to cooling of the armature surface
