description: The negatively charged silicon vacancy ($\mathrm{V_{Si}^-}$) in silicon carbide is a well-studied point defect for quantum applications. At the same time, a closer inspection of ensemble photoluminescence and electron paramagnetic resonance measurements reveals an abundance of related but so far unidentified signals. In this study, we search for defects in 4H-SiC that explain the above magneto-optical signals in a defect database generated by Automatic Defect Analysis and Qualification (ADAQ) workflows. This search reveals only one class of atomic structures that exhibit silicon-vacancy-like properties in the data: a carbon antisite ($\mathrm{C_{Si}}$) within sub-nanometer distances from the silicon vacancy only slightly alters the latter without affecting the charge or spin state. Such a perturbation is energetically bound. We consider the formation of $\mathrm{V_{Si}^-+C_{Si}}$ up to 2 nm distance and report their zero phonon lines and zero field splitting values. In addition, we perform high-resolution photoluminescence experiments in the silicon vacancy region and find an abundance of lines. Comparing our computational and experimental results, several configurations show great agreement. Our work demonstrates the effectiveness of a database with high-throughput results in the search for defects in quantum applications.

description: We present ZodiPy, a modern and easy-to-use Python package for modeling the zodiacal emission seen by an arbitrary Solar System observer, which can be used for the removal of both thermal emission and scattered sunlight from interplanetary dust in astrophysical data. The code implements the COBE Diffuse Infrared Background Experiment (DIRBE) interplanetary dust model and the Planck extension, which allows for zodiacal emission predictions at infrared wavelengths in the 1.25-240 $μ$m range and at microwave frequencies in the 30-857 GHz range. The predicted zodiacal emission may be extrapolated to frequencies and wavelengths not covered by the built-in models to produce forecasts for future experiments. ZodiPy attempts to enable the development of new interplanetary dust models by providing the community with an easy-to-use interface for testing both current and future models. We demonstrate how the software can be used by creating simulated zodiacal emission timestreams for the DIRBE experiment and show that these agree with corresponding timestreams produced with the DIRBE Zodiacal Light Prediction Software. We also make binned maps of the zodiacal emission as predicted to be observed by DIRBE and compare them with the DIRBE calibrated individual observations (CIO).

description: In 2016, the Research unit of the University of Michigan Library set out to gain a more complete understanding of the work performed by its service expert staff. Service experts were defined as public services professionals who provide expertise or services to campus. Among these service experts are subject specialist liaison librarians, and functional expert data and visualization librarians, etc. In partnership with Bridgeport Consulting LLC of Ann Arbor, Michigan, this functional analysis data collection tool was developed and distributed to service expert staff in July, 2016. Research unit managers created an exhaustive list of “functions,” or activities, that a service expert might perform in the course of a day’s work. An Excel spreadsheet (the “Tool”) was created from this list, which allowed each service expert to enter an approximation of his or her annual effort spent on each individual function.

description: We propose a novel technique of microscopy to overcome the effects of both scattering and limitation of the accessible depth due to the objective working distance. By combining Laser Optical Feedback Imaging (LOFI) with Acoustic Photon Taging (APT) and Synthetic Aperture (SA) refocusing we demonstrate an ultimate shot noise sensitivity at low power (required to preserve the tissues) and a high resolution beyond the microscope working distance. More precisely, with a laser power of 10mW, we obtain images with a micrometric resolution over ~8 transport mean free paths, corresponding to 1.3 times the microscope working distance. Various applications such as biomedical diagnosis, research and development of new drugs and therapies can benefit from our imaging setup.

It is revealed that in the beginning of the Paleogene alternating of paleointensity variations of little amplitude (about 0.5 Ho, where Ho is the value of modern geomagnetic field taken as 40 mkT) and bursts of large amplitude (up to 5 Ho) took place. At the end of the Paleogene paleointensity variations occur only with a little amplitude.

description: We define integrability preserving Yang-Baxter deformations of symmetric space sigma models with non-semi-simple symmetry group, in particular the flat space string, using only the essential structures of a symmetric space sigma model. For homogeneous deformations, the Lax connection is of the same form as the semi-simple case, although the R operator no longer satisfies a freestanding operator equation. For inhomogeneous deformations, the form of the Lax connection needs to be relaxed, by modifying the underlying algebra. We illustrate the construction by discussing nonabelian deformations of three dimensional Minkowski space.

description: Spontaneous order of layer pseudospins in two-dimensional bilayers is common in quantum Hall systems, where it is responsible for hysteretic responses to gate fields in states with Ising order, and giant drag voltages in states with XY (spontaneous inter-layer phase coherence) order. In this article we predict that layer pseudospin order will also occur in double-moiré strongly correlated two-dimensional electron systems. We comment on similarities and differences in the competition between the two types of order in quantum Hall and double-moiré systems, and relate our findings to previous work on Falicov-Kimball models of electronic ferroelectrics.

description: Recently a new wave of interest to spectroscopy of radioactive compounds has raised due to successful applications of the new experimental ISOL/CRIS technique to optical spectroscopy of radium monofluoride molecules. This opens great prospects to searches of the effects connected with ``new physics'' which point on deviations of the physical laws from those established by Standard Model of elementary particles. Considerable advantages in experiments for search for such effects would be provided by the abilities to trap the working molecules, their laser-coolability and presence of co-magnitometer molecular states and also a variety of accessible nuclear isotopes of the elements in the molecule with different nuclear multipole moments. Laser-coolable polyatomic molecular ions containing Ra nuclei shall meet the above criteria and in the present article we are considering a number of prospective molecular ions and calculating their electronic structure and molecular properties.

description: Electron transport in electric-field-driven tight-binding lattice coupled to fermion baths is comprehensively studied. We reformulate the problem by using the scattering state method within the Coulomb gauge. Calculations show that the formulation justifies direct access to the steady-state bypassing the time-transient calculations, which then makes the steady-state methods developed for quantum dot theories applicable to lattice models. We show that the effective temperature of the hot-electron induced by a DC electric field behaves as $T_{\rm eff}=Cγ(Ω/Γ)$ with a numerical constant $C$, tight-binding parameter $γ$, the Bloch oscillation frequency $Ω$ and the damping parameter $Γ$. In the small damping limit $Γ/Ω\to 0$, the steady-state has a singular property with the electron becoming extremely hot in an analogy to the short-circuit effect. This leads to the conclusion that the dissipation mechanism cannot be considered as an implicit process, as treated in equilibrium theories. Finally, using the energy flux relation, we derive a steady-state current for interacting models where only on-site Green's functions are necessary.

description: To improve the robustness of ﬁber-reinforced plastics (FRP) in bolted joints, local metal-hybridization of the FRP laminate can be performed to obtain an FRP-based ﬁber metal laminate (FML) of increased bearing strength. This contribution presents the ﬁrst modeling framework able to predict the entire fatigue degradation process of such FRP-based FML bolted joints from damage initiation until ultimate failure, including the safety-relevant bolted joint failure mode. For this purpose, each laminate constituent material (i.e. metallic inlays and FRP plies) is analyzed by an own physically motivated continuum damage model. To predict the fatigue crack initiation and growth in the metallic inlays, the framework deploys a newly developed continuum damage approach, which uses a cyclic elasto-plastic strain energy increment as primary fatigue metric. Based on its constitutive equations, the inlay damage model is able to predict a fatigue crack’s location and growth direction, both in the low- and the high-cycle fatigue regime. To account for the fatigue damage of the FRP plies, an energy-based fatigue damage approach for FRP composites, recently presented and validated by the authors, is applied. A comprehensive damage assessment is achieved as both fatigue models are accompanied by respective static damage models. The algorithms are implemented as one user-material (UMAT) subroutine in the commercial ﬁnite element software ABAQUS/Implicit. After the separate validation of the inlay damage model, the FML damage modeling framework is validated for open hole tension and T-bolt joint setups.

description: Soft robotics technology can aid in achieving United Nations Sustainable Development Goals (SDGs) and the Paris Climate Agreement through development of autonomous, environmentally responsible machines powered by renewable energy. By utilizing soft robotics, we can mitigate the detrimental effects of climate change on human society and the natural world through fostering adaptation, restoration, and remediation. Moreover, the implementation of soft robotics can lead to groundbreaking discoveries in material science, biology, control systems, energy efficiency, and sustainable manufacturing processes. However, to achieve these goals, we need further improvements in understanding biological principles at the basis of embodied and physical intelligence, environment-friendly materials, and energy-saving strategies to design and manufacture self-piloting and field-ready soft robots. This paper provides insights on how soft robotics can address the pressing issue of environmental sustainability. Sustainable manufacturing of soft robots at a large scale, exploring the potential of biodegradable and bioinspired materials, and integrating onboard renewable energy sources to promote autonomy and intelligence are some of the urgent challenges of this field that we discuss in this paper. Specifically, we will present field-ready soft robots that address targeted productive applications in urban farming, healthcare, land and ocean preservation, disaster remediation, and clean and affordable energy, thus supporting some of the SDGs. By embracing soft robotics as a solution, we can concretely support economic growth and sustainable industry, drive solutions for environment protection and clean energy, and improve overall health and well-being.
Efficient sliding locomotion of three-link bodies with inertia

description: Many previous studies of sliding locomotion have assumed that body inertia is negligible. Here we optimize the kinematics of a three-link body for efficient locomotion and include among the kinematic parameters the temporal period of locomotion, or equivalently, the body inertia. The optimal inertia is non-negligible when the coefficient of friction for sliding transverse to the body axis is small. Inertia is also significant in a few cases with relatively large coefficients of friction for transverse and backward sliding, and here the optimal motions are less sensitive to the inertia parameter. The optimal motions seem to converge as the number of frequencies used is increased from one to four. For some of the optimal motions with significant inertia we find dramatic reductions in efficiency when the inertia parameter is decreased to zero. For the motions that are optimal with zero inertia, the efficiency decreases more gradually when we raise the inertia to moderate and large values.

title: “Mixed Up in the Coal Camp”: Interethnic, Family, and Community Exchanges in Matewan During the West Virginia Mine Wars, 1900-1922
Creators: name: Gourley, Lela Dawn
Publisher: name: Old Dominion University Libraries
Year: 2019

description: The West Virginia Mine Wars are etched in the popular memory of West Virginians, who view these events as an important part of their identity as Mountaineers; yet, there is still much historians do not know about the Mine Wars, especially when concentrating on the perspectives and experiences of the working-class miners. These everyday miners and their families are the topic of this thesis. Using oral histories from the Matewan Development Center Records housed in the W.L. Eury Appalachian Collection at Appalachian State University in Boone, North Carolina, this thesis argues that community-building across ethnic and racial lines within Matewan’s coal camps was not only possible, but occurred at a degree unmatched by other West Virginia industrial communities. In these camps, miners lived less segregated lives than their counterparts, presenting a fairly mixed community in which inter-ethnic exchanges laid an early foundation for cross-ethnic organization and resistance against the coal operators. As miners in southern West Virginia struggled to unionize against pro-coal forces and their attempts to divide miners and the larger community along racial and ethnic lines, miners turned to their foundation of community in the coal camp to withstand strike tactics, including their almost two year banishment to tent colonies. Tent colonies presented opportunities for informal exchanges between miners – exchanges that were just as valuable as formal exchanges in their day to day lives. By examining both formal and informal exchanges between Matewan’s mining population, this thesis argues that the “mixed up” quality of Stone Mountain Coal Corporation’s coal camps stimulated a shared working-class identity that was then mobilized by the United Mine Workers of America (UMWA) on a scale previously not achieved in West Virginia’s southern coalfields.
Steady-State Entanglement by Engineered Quasi-Local Markovian Dissipation

description: We characterize and construct time-independent Markovian dynamics that drive a finite-dimensional multipartite quantum system into a target (pure) entangled steady state, subject to physical locality constraints. In situations where the desired stabilization task can not be attained solely based on local dissipative means, we allow for local Hamiltonian control or, if the latter is not an option, we suitably restrict the set of admissible initial states. In both cases, we provide algorithms for constructing a master equation that achieves the intended objective and show how this can genuinely extend the manifold of stabilizable states. In particular, we present quasi-local control protocols for dissipatively engineering multipartite GHZ "cat" states and W states on $n$ qubits. For GHZ states, we find that no scalable procedure exists for achieving stabilization from arbitrary initial states, whereas this is possible for a target W state by a suitable combination of a two-body Hamiltonian and dissipators. Interestingly, for both entanglement classes, we show that quasi-local stabilization may be scalably achieved conditional to initialization of the system in a large, appropriately chosen subspace.

We still find that our conclusion on the lack of universality between radial- and angular-momentum Regge trajectories is valid.

Year: 2019

description: Hurricane Harvey (HH) is considered to be the first natural disaster where social-network applications to request help surpassed already overloaded 911 systems (Seetharaman & Wells, 2017). Increasing interpersonal connectivity via Facebook, Twitter, and other social media sites correspond to an increasing need for researchers and responders to recognize how people use social media platforms to connect, share, and receive information especially during times of crisis such as natural disasters. Heightened public perceptions and expectations of response efforts in the digital era make it especially important for first responders to evaluate, monitor, and adapt to these shifts in communication. Disaster-relief groups and emergency responders are looking for help to navigate in this new landscape in order to better serve their constituents and explore new, innovative ways to improve both their efficiency and their empathy. Emergency-response managers must act fast to prevent incorrect or misleading information from reaching the public. Some organizations are expressing interest in social media as a potentially cost-efficient way to disseminate information and official communication. However, as research has shown, innovations take time to diffuse (Rogers, 2003). In this thesis, I examined the diffusion of social media in the ways the U.S. Coast Guard (USCG) (first responder) and the public communicate during crises. Moreover, I examined facilitative and inhibitive factors shaping the diffusion of digital innovations within the USCG. I conclude that the pacing of the diffusion of social media among everyday users is incredibly rapid and, concurrently, is pressuring crisis communication systems like the USCG to quickly adopt these new innovations. I further conclude that Hurricane Harvey should function as a historical catalyst, a clarion call, that government agencies should incorporate social media and associated digital media to improve their future emergency response operations because lives will depend on it.
Linear stability analysis via simulated annealing and accelerated relaxation

description: Simulated annealing (SA) is a kind of relaxation method for finding equilibria of Hamiltonian systems. A set of evolution equations is solved with SA, which is derived from the original Hamiltonian system so that the energy of the system changes monotonically while preserving Casimir invariants inherent to noncanonical Hamiltonian systems. The energy extremum reached by SA is an equilibrium. Since SA searches for an energy extremum, it can also be used for stability analysis when initiated from a state where a perturbation is added to an equilibrium. The procedure of the stability analysis is explained, and some examples are shown. Because the time evolution is computationally time consuming, efficient relaxation is necessary for SA to be practically useful. An acceleration method is developed by introducing time dependence in the symmetric kernel used in the double bracket, which is part of the SA formulation described here. An explicit formulation for low-beta reduced magnetohydrodynamics (MHD) in cylindrical geometry is presented. Since SA for low-beta reduced MHD has two advection fields that relax, it is important to balance the orders of magnitude of these advection fields.

description: Securing multimedia data has become of utmost importance especially in the applications related to military purposes. With the rise in development in computer and internet technology, multimedia data has become the most convenient method for military training. An innovative encryption algorithm for videos compressed using H.264 was proposed to safely exchange highly confidential videos. To maintain a balance between security and computational time, the proposed algorithm shuffles the video frames along with the audio, and then AES is used to selectively encrypt the sensitive video codewords. Using this approach unauthorized viewing of the video file can be prevented and hence this algorithm provides a high level of security. A comparative study of the proposed algorithm with other existing algorithms has been put forward in this paper to prove the effectiveness of the proposed algorithm.

Our results pave a promising way to realize ultra-compact devices operating in the terahertz region.

Focusing on three dimensions, we analyze the implications of a UV complete, all-loop order 4-point amplitude of pions in terms of correlation functions defined on the celestial circle. We find these retain many key features from the previously studied tree-level case, such as their relation to Generalized Free Field theories and crossing-symmetry, but also incorporate new properties such as IR/UV softness and S-matrix metastable states. In particular, to understand unitarity, we propose a form of the optical theorem that controls the imaginary part of the correlator based solely on the presence of these resonances. We also explicitly analyze the conformal block expansions and factorization of four-point functions into three-point functions. We find that summing over resonances is key for these factorization properties to hold. We end with some topics for future study.

description: We present a new transfer procedure for graphene using acetic acid, which removes the residue that is common in standard acetone treatments. Post-transfer samples cleaned with acetic acid and acetone were characterized using Raman spectroscopy and atomic force microscopy for comparison. We further illustrate the quality of our transfer process by using fluorescence quenching to create an optical map of surface contaminants.

description: We present the discovery of a Type Ia supernova (SN) at redshift $z = 1.914$ from the CANDELS multi-cycle treasury program on the \textit{Hubble Space Telescope (HST)}. This SN was discovered in the infrared using the Wide-Field Camera 3, and it is the highest-redshift Type Ia SN yet observed. We classify this object as a SN\,Ia by comparing its light curve and spectrum with those of a large sample of Type Ia and core-collapse supernovae (SNe). Its apparent magnitude is consistent with that expected from the $Λ$CDM concordance cosmology. We discuss the use of spectral evidence for classification of $z > 1.5$ SNe\,Ia using {\it HST} grism simulations, finding that spectral data alone can frequently rule out SNe\,II, but distinguishing between SNe\,Ia and SNe\,Ib/c can require prohibitively long exposures. In such cases, a quantitative analysis of the light curve may be necessary for classification. Our photometric and spectroscopic classification methods can aid the determination of SN rates and cosmological parameters from the full high-redshift CANDELS SN sample.

description: Aims. This study aims to explore the relationship between the physical properties of different galaxy subclasses and their environment based on the analysis of 31 631 VIMOS Public Extragalactic Redshift Survey (VIPERS) galaxies observed at 0.5 < z < 0.9. Methods. We use the results of an unsupervised clustering algorithm to distinguish 11 subclasses of VIPERS galaxies based on the multi-dimensional feature space defined by rest-frame UV to NIR colours presented in Siudek et al (2018a). We investigate the relationship between the properties of these subclasses of galaxies and their local environment, defined as the galaxy density contrast derived from the 5th nearest neighbour technique. Results. We confirm that the galaxy population-density relation is already in place at z ~ 0.9, with the blue galaxy fraction decreasing with density, compensated by an increase of the red fraction. On average red galaxies in the high-density environment are larger by 28% than the ones in low-density environments. In particular, we find one group of galaxies, subclass C3, whose increase of size with time can be explained mainly as the result of mergers; for other red subclasses, mergers would not seem to play a major role (subclass C2) or play a negligible role (subclass C1). The properties of the green galaxies (subclasses C4-6) depend on whether their stellar mass is above or below a transition mass. Low-mass green galaxies appear to have grown through secular processes, while in high-mass green galaxies mass assembly appears to be dominated by mergers. When it comes to blue galaxies, the trend of decreasing fraction with denser environments seen for the group as a whole (subclasses C7-11) is found to be driven mostly by one group of galaxies, subclass C10. These are compact low-mass galaxies with high sSFRs, that are preferentially found in low-density environments.

description: AliCPT is the first Chinese cosmic microwave background (CMB) experiment which will make the most precise measurements of the CMB polarization in the northern hemisphere. The key science goal for AliCPT is the detection of primordial gravitational waves (PGWs). It is well known that an epoch of cosmic inflation, in the very early universe, can produce PGWs, which leave an imprint on the CMB in form of odd parity $B$-mode polarization. In this work, we study the performance of the component separation and parameter estimation pipelines in context of constraining the value of the tensor-to-scalar ratio. Based on the simulated data for one observation season, we compare five different pipelines with different working principles. Three pipelines perform component separation at map or spectra level before estimating $r$ from the cleaned spectra, while the other two pipelines performs a global fit for both foreground parameters and $r$. We also test different methods to account for the effects of time stream filtering systematics. This work shows that our pipelines provide consistent and robust constraints on the tensor-to-scalar ratio and a consistent sensitivity $σ(r) \sim 0.02$. This showcases the potential of precise $B$-mode polarization measurement with AliCPT-1. AliCPT will provide a powerful opportunity to detect PGWs, which is complementary with various ground-based CMB experiments in the southern hemisphere.

Neutron star crust properties: comparison between the compressible liquid-drop model and the extended Thomas-Fermi approach

description: We present a detailed analysis of three models predicting the properties of non-uniform matter in the crust of neutron stars: the compressible liquid-drop model, the fourth order Extended Thomas Fermi (ETF) method, and ETF plus Strutinsky integral (ETFSI) correction. The former treats the nuclear clusters as uniform hard spheres, the second takes into account the density distribution which can be different for neutrons and protons, and the last one includes the proton shell effects within the Strutinsky approach. The purpose of this work is to understand the importance of the improvements in the nuclear modeling and to analyze the quantities which are the most sensitive to them. We find that thermodynamic quantities such as pressure, energy and chemical potential, as well as the electron fraction, are in very good agreement among the three models. This confirms previous results where we have shown that the improvement in the finite-size description of the nuclear clusters has a small impact on these quantities, since they are mainly constrained by the bulk properties. The refinements in the finite-size modeling are shown to impact mostly the composition of the nuclear clusters ($Z_{cl}$, $N_{cl}$) in an ordering which ranks according to the leptodermous expansion. This analysis is performed considering both the r-cluster and the e-cluster representations. The proton shell effects are shown to stabilize $Z_{cl}$, which consequently impacts the neutron number $N_{cl}$ as well.

description: Reaction networks are commonly used to model the evolution of populations of species subject to transformations following an imposed stoichiometry. This paper focuses on the efficient characterisation of dynamical properties of Discrete Reaction Networks (DRNs). DRNs can be seen as modelling the underlying discrete nondeterministic transitions of stochastic models of reactions networks. In that sense, any proof of non-reachability in DRNs directly applies to any concrete stochastic models, independently of kinetics laws and constants. Moreover, if stochastic kinetic rates never vanish, reachability properties are equivalent in the two settings. The analysis of two global dynamical properties of DRNs is addressed: irreducibility, i.e., the ability to reach any discrete state from any other state; and recurrence, i.e., the ability to return to any initial state. Our results consider both the verification of such properties when species are present in a large copy number, and in the general case. The obtained necessary and sufficient conditions involve algebraic conditions on the network reactions which in most cases can be verified using linear programming. Finally, the relationship of DRN irreducibility and recurrence with dynamical properties of stochastic and continuous models of reaction networks is discussed.
