description: We study Abelian braiding statistics of loop excitations in three-dimensional (3D) gauge theories with fermionic particles and the closely related problem of classifying 3D fermionic symmetry-protected topological (FSPT) phases with unitary symmetries. It is known that the two problems are related by turning FSPT phases into gauge theories through gauging the global symmetry of the former. We show that there exist certain types of Abelian loop braiding statistics that are allowed only in the the presence of fermionic particles, which correspond to 3D "intrinsic" FSPT phases, i.e., those that do not stem from bosonic SPT phases. While such intrinsic FSPT phases are ubiquitous in 2D systems and in 3D systems with anti-unitary symmetries, their existence in 3D systems with unitary symmetries was not confirmed previously due to the fact that strong interaction is necessary to realize them. We show that the simplest unitary symmetry to support 3D intrinsic FSPT phases is $\mathbb{Z}_2\times\mathbb{Z}_4$. To establish the results, we first derive a complete set of physical constraints on Abelian loop braiding statistics. Solving the constraints, we obtain all possible Abelian loop braiding statistics in 3D gauge theories, including those that correspond to intrinsic FSPT phases. Then, we construct exactly soluble state-sum models to realize the loop braiding statistics. These state-sum models generalize the well-known Crane-Yetter and Dijkgraaf-Witten models.

Radiative-transfer models for explosions from rotating and non-rotating single WC stars. Implications for SN1998bw and LGRB/SNe

description: Using 1-D non-Local-Thermodynamic-Equilibrium time-dependent radiative-transfer simulations, we study the ejecta properties required to match the early and late-time photometric and spectroscopic properties of supernovae (SNe) associated with long-duration gamma-ray bursts (LGRBs). To match the short rise time, narrow light curve peak, and extremely broad spectral lines of SN1998bw requires a model with <3Msun ejecta but a high explosion energy of a few 1e52erg and 0.5Msun of Ni56. However the relatively high luminosity, the presence of narrow spectral lines of intermediate mass elements, and the low ionization at the nebular stage are matched with a more standard C-rich Wolf-Rayet (WR) star explosion, with an ejecta of >10Msun, an explosion energy >1e51erg, and only 0.1Msun of Ni56. As the two models are mutually exclusive, the breaking of spherical symmetry is essential to match the early/late photometric/spectroscopic properties of SN1998bw. This conclusion confirms the notion that the ejecta of SN1998bw is aspherical on large scales. More generally, with asphericity, the energetics and Ni56 mass of LGRB/SNe are reduced and their ejecta mass is increased, favoring a massive fast-rotating Wolf-Rayet star progenitor. Contrary to persisting claims in favor of the proto-magnetar model for LGRB/SNe, such progenitor/ejecta properties are compatible with collapsar formation. Ejecta properties of LGRB/SNe inferred from 1D radiative-transfer modeling are fundamentally flawed.

description: Fractionalization is a hallmark of spin-liquid behavior; it typically leads to response functions consisting of continua instead of sharp modes. However, microscopic processes can enable the formation of short-distance bound states of fractionalized excitations, despite asymptotic deconfinement. Here we study such bound-state formation for the $Z_2$ spin liquid realized in Kitaev's honeycomb compass model, supplemented by a kekule distortion of the lattice. Bound states between flux pairs and Majorana fermions form in the Majorana band gaps. We calculate the dynamic spin susceptibility and show that bound states lead to sharp modes in the magnetic response of the spin liquid, with the momentum dependence of the corresponding spectral weight encoding internal symmetry of the bound state. As a byproduct, we also show that isolated fluxes may produce Majorana bound states at exactly zero energy. Generalizations and implications of the results are discussed.

description: How to detect quantum correlations in bi-partite scenarios using a split many-body system and collective measurements on each party? We address this question by deriving entanglement witnesses using either only first or first and second order moments of local collective spin components. In both cases, we derive optimal witnesses for spatially split spin squeezed states in the presence of local white noise. We then compare the two optimal witnesses with respect to their resistance to various noise sources operating either at the preparation or at the detection level. We finally evaluate the statistics required to estimate the value of these witnesses when measuring a split spin-squeezed Bose-Einstein condensate. Our results can be seen as a step towards Bell tests with many-body systems.

description: Due to the lack of Black representation in Germany for Afro-Germans, many have turned to media from the United States to relate to and understand their identities. Using hip-hop, radio, and podcasts, Afro-Germans have expressed how they relate to both their Germanness and their Blackness unapologetically declaring where they come from and conferring with other Afro-Germans in a communal space about their experiences as Black people in Germany. In the 1980s, these kinds of conversations were often done in literary circles, however, from the 1990s and into the 21ˢᵗ century, oral media made the stories of Afro-Germans available to a wider audience. In this paper, I argue that American forms of media such as hip-hop, Black radio, and podcasts have influenced Afro-Germans to create their own media in a space where their narratives are not often heard. Hip-hop created by Afro-Germans specifically emphasizes how their identity is perceived in German society while radio that incorporates Afro-German experiences has connected their stories to that of the wider African diaspora. The connection to the United States through radio allows for a collective Black consciousness amongst diasporans and gives Afro-Germans the opportunity to explore how they relate to their nation and their heritage. In these discussions amongst people of African descent in both the United States and Germany, the theme of Afrocentrism is a core component of seeking out one’s heritage. Through the establishment of their own podcasts, Afro-Germans have created media to broadcast their intimate experiences of rediscovering their Black identities while growing up in a Eurocentric society. Ample research on the influence of American hip-hop and rap culture in Germany exists, and with my research, I expand the scope further to look specifically at how Afro-Germans discuss their identities with African Americans via radio and with each other through the art of podcasting. By creating their own media and touching on topics representing their community, Afro-Germans define how they wish to be seen by the rest of German society.
Balanced Viscosity solutions to a rate-independent system for damage

description: This article is the third one in a series of papers by the authors on vanishing-viscosity solutions to rate-independent damage systems. While in the first two papers [KRZ13, KRZ15] the assumptions on the spatial domain $Ω$ were kept as general as possible (i.e. nonsmooth domain with mixed boundary conditions), we assume here that $\partialΩ$ is smooth and that the type of boundary conditions does not change. This smoother setting allows us to derive enhanced regularity spatial properties both for the displacement and damage fields. Thus, we are in a position to work with a stronger solution notion at the level of the viscous approximating system. The vanishing-viscosity analysis then leads us to obtain the existence of a stronger solution concept for the rate-independent limit system. Furthermore, in comparison to [KRZ13, KRZ15], in our vanishing-viscosity analysis we do not switch to an artificial arc-length parameterization of the trajectories but we stay with the true physical time. The resulting concept of Balanced Viscosity solution to the rate-independent damage system thus encodes a more explicit characterization of the system behavior at time discontinuities of the solution.

description: The Pearson product-moment correlation coefficient (rp) and the Spearman rank correlation coefficient (rs) are widely used in psychological research. We compare rp and rs on 3 criteria: variability, bias with respect to the population value, and robustness to an outlier. Using simulations across low (N = 5) to high (N = 1,000) sample sizes we show that, for normally distributed variables, rp and rs have similar expected values but rs is more variable, especially when the correlation is strong. However, when the variables have high kurtosis, rp is more variable than rs. Next, we conducted a sampling study of a psychometric dataset featuring symmetrically distributed data with light tails, and of 2 Likert-type survey datasets, 1 with light-tailed and the other with heavy-tailed distributions. Consistent with the simulations, rp had lower variability than rs in the psychometric dataset. In the survey datasets with heavy-tailed variables in particular, rs had lower variability than rp, and often corresponded more accurately to the population Pearson correlation coefficient (Rp) than rp did. The simulations and the sampling studies showed that variability in terms of standard deviations can be reduced by about 20% by choosing rs instead of rp. In comparison, increasing the sample size by a factor of 2 results in a 41% reduction of the standard deviations of rs and rp. In conclusion, rp is suitable for light-tailed distributions, whereas rs is preferable when variables feature heavy-tailed distributions or when outliers are present, as is often the case in psychological research.

description: We introduce an effective point-particle action for generic particles living in a zero-temperature superfluid. This action describes the motion of the particles in the medium at equilibrium as well as their couplings to sound waves and generic fluid flows. While we place the emphasis on elementary excitations such as phonons and rotons, our formalism applies also to macroscopic objects such as vortex rings and rigid bodies interacting with long-wavelength fluid modes. Within our approach, we reproduce phonon decay and phonon-phonon scattering as predicted using a purely field-theoretic description of phonons. We also correct classic results by Landau and Khalatnikov on roton-phonon scattering. Finally, we discuss how phonons and rotons couple to gravity, and show that the former tend to float while the latter tend to sink but with rather peculiar trajectories. Our formalism can be easily extended to include (general) relativistic effects and couplings to additional matter fields. As such, it can be relevant in contexts as diverse as neutron star physics and light dark matter detection.

A Control Theoretic Approach to Simultaneously Estimate Average Value of Time and Determine Dynamic Price for High-occupancy Toll Lanes

description: The dynamic pricing problem of a freeway corridor with high-occupancy toll (HOT) lanes was formulated and solved based on a point queue abstraction of the traffic system [Yin and Lou, 2009]. However, existing pricing strategies cannot guarantee that the closed-loop system converges to the optimal state, in which the HOT lanes' capacity is fully utilized but there is no queue on the HOT lanes, and a well-behaved estimation and control method is quite challenging and still elusive. This paper attempts to fill the gap by making three fundamental contributions: (i) to present a simpler formulation of the point queue model based on the new concept of residual capacity, (ii) to propose a simple feedback control theoretic approach to estimate the average value of time and calculate the dynamic price, and (iii) to analytically and numerically prove that the closed-loop system is stable and guaranteed to converge to the optimal state, in either Gaussian or exponential manners.

Security Constrained Multi-Stage Transmission Expansion Planning Considering a Continuously Variable Series Reactor

Publisher: name: arXiv
Year: 2017
Subjects: subject: Optimization and Control (math.OC)

description: This paper introduces a Continuously Variable Series Reactor (CVSR) to the transmission expansion planning (TEP) problem. The CVSR is a FACTS-like device which has the capability of controlling the overall impedance of the transmission line. However, the cost of the CVSR is about one tenth of a similar rated FACTS device which potentially allows large numbers of devices to be installed. The multi-stage TEP with the CVSR considering the $N-1$ security constraints is formulated as a mixed integer linear programming model. The nonlinear part of the power flow introduced by the variable reactance is linearized by a reformulation technique. To reduce the computational burden for a practical large scale system, a decomposition approach is proposed. The detailed simulation results on the IEEE 24-bus and a more practical Polish 2383-bus system demonstrate the effectiveness of the approach. Moreover, the appropriately allocated CVSRs add flexibility to the TEP problem and allow reduced planning costs. Although the proposed decomposition approach cannot guarantee global optimality, a high level picture of how the network can be planned reliably and economically considering CVSR is achieved.

description: We study classical two-dimensional frustrated Heisenberg models with generically incommensurate groundstates. A new theory for the spin-nematic "order by disorder" transition is developed based on the self-consistent determination of the effective exchange coupling bonds. In our approach, fluctuations of the constraint field imposing conservation of the local magnetic moment drive nematicity at low temperatures. The critical temperature is found to be highly sensitive to the peak helimagnetic wavevector, and vanishes continuously when approaching rotation symmetric Lifshitz points. Transitions between symmetry distinct nematic orders may occur by tuning the exchange parameters, leading to lines of bicritical points.

This article argues that critical theories of the public sphere (in Habermas, but also in Negt and Kluge as well as Fraser) neglect the central social field of labour and labour-policy disputes and that a re-actualisation and re-focusing is necessary: We define the dynamics of globalisation, commodification and digitalisation as sequences of a renewed structural transformation both of social self-understanding and gainful employment. With the help of a multi-level model of labour-political public spheres and counter-public spheres, class mobilisations can be examined through a lens of public sphere theory and important moments of labour-political conflicts can also be reflected on their communicative conditions. This is exemplified by two vignettes.

description: Flat-fading channel models are usually invoked for analyzing the performance of massive spatial modulation multiple-input multiple-output (SM-MIMO) systems. However, in the context of broadband SM transmission, the severe inter-symbol-interference (ISI) caused by the frequency-selective fading channels can not be ignored, which leads to very detrimental effects on the achievable system performance, especially for single-carrier SM (SC-SM) transmission schemes. To the best of the author's knowledge, none of the previous researchers have been able to provide a thorough analysis on the achievable spectral efficiency (SE) of the massive SC-SM MIMO uplink transmission. In this context, the uplink SE of single-cell massive SC-SM MIMO system is analyzed, and a tight closed-form lower bound is proposed to quantify the SE when the base station (BS) uses maximum ratio (MR) combining for multi-user detection. The impacts of imperfect channel estimation and transmit correlation are all considered. Monte Carlo simulations are performed to verify the tightness of our proposed SE lower bound. Both the theoretical analysis and simulation results show that the SE of uplink single-cell massive SC-SM MIMO system has the potential to outperform the uplink SE achieved by single-antenna UEs.

Within the framework of the pure spin current model based on the bulk spin Hall effect (SHE), the ratio of the spin Hall-induced anomalous Hall effect (SH-AHE) to SMR should be equal to the ratio of the field-like torque (FLT) to damping-like torque (DLT). We perform a quantitative study of SMR, SH-AHE, and SOTs in a series of thulium iron garnet/platinum or Tm3Fe5O12/Pt heterostructures with different Tm3Fe5O12 thicknesses, where Tm3Fe5O12 is a ferrimagnetic insulator with perpendicular magnetic anisotropy. We find the ratio between measured effective fields of FLT and DLT is at least 2 times larger than the ratio of the SH-AHE to SMR. In addition, the bulk SHE model grossly underestimates the spin torque efficiency of FLT. Our results reveal deficiencies of the bulk SHE model and also address the importance of interfacial effects such as the Rashba and magnetic proximity effects in magnetic insulator/heavy metal heterostructures.

description: Thermodynamics is one of the oldest and well-established branches of physics that sets boundaries to what can possibly be achieved in macroscopic systems. While it started as a purely classical theory, it was realized in the early days of quantum mechanics that large quantum devices, such as masers or lasers, can be treated with the thermodynamic formalism. Remarkable progress has been made recently in the miniaturization of heat engines all the way to the single Brownian particle as well as to a single atom. However, despite several theoretical proposals, the implementation of heat machines in the fully quantum regime remains a challenge. Here, we report an experimental realization of a quantum absorption refrigerator in a system of three trapped ions, with three of its normal modes of motion coupled by a trilinear Hamiltonian such that heat transfer between two modes refrigerates the third. We investigate the dynamics and steady-state properties of the refrigerator and compare its cooling capability when only thermal states are involved to the case when squeezing is employed as a quantum resource. We also study the performance of such a refrigerator in the single shot regime, and demonstrate cooling below both the steady-state energy and the benchmark predicted by the classical thermodynamics treatment.

description: We treat protein folding as the molecular self-assembly, while unfolding is viewed as disassembly. Self-assembly and disassembly (fracture) are two opposite non-equilibrium dynamic processes; however, they cannot be converted to each other by a simple time variable reversal. Fracture is typically a much faster process than self-assembly. Self-assembly is often an exponentially decaying process, since energy relaxes due to dissipation, while fracture may be a constant rate process as the driving force is opposed by damping. Typically, protein folding takes two orders of magnitude longer time than unfolding, and it consumes a lot of computational resources to model folding. Based on energy dissipation rates, we suggest a mathematical transformation of variables, which makes it possible to view self-assembly as time-reversed disassembly, thus folding can be studied as reversed unfolding. We investigate the molecular dynamics modeling of folding and unfolding of the short Trp-cage protein. Folding time constitutes about 800 ns while unfolding (denaturation) takes only about 5.0 ns, and therefore, fewer computational resources are needed for its simulation. This "RetroFold" approach can be used for the design of a novel computation algorithm, which, while approximate, is less time-consuming than traditional folding algorithms.

description: We conducted the molecular dynamics (MD) simulation of both folding and unfolding using the Trp-Cage amino acid sequence with an extended initial conformation built by the LEaP module of AMBER. The linear conformation of this protein was designed using the Avogadro software. The 3D molecular structure (PDB ID: 1L2Y) of Trip-Cage was determined by the Nuclear Magnetic Resonance (NMR) method in the solution as a set (n =38) of stable conformations obtained from the RCSB Protein Data Bank. The MD simulations included the following phases: minimization (500 cycles), heating (50 ps), and equilibration (production) at 325 K (800 ns) for folding and at 473 K (5 ns) for unfolding according to the standard protocols published elsewhere. Our MD simulations were fully unrestrained and carried out in the canonical ensemble using the SANDER module available for Linux/Unix. The Berendsen thermostat was implemented for temperature control and the SHAKE algorithm to constrain the length of covalent bonds, including the hydrogen atoms. The ff99 force field was used as it was previously employed for similar modeling. Solvation effects were incorporated using the Generalized Born model, as implemented in AMBER. The Rosetta crystallographic refinement protocol was implemented to assess the conformational stability of the folded and unfolded protein conformations obtained from the previous MD simulations.

description: The origin of the electronic nematicity and its remarkable material-dependence are famous longstanding unsolved issues in Fe-based superconductors. To attack these issues, we focus on the in-plane anisotropy of the resistivity: In the nematic state in FeSe, the relation $ρ_x>ρ_y$ holds, where $ρ_{x(y)}$ is the resistivity along the longer (shorter) Fe-Fe axis. In contrast, the opposite anisotropy $ρ_xρ_y$) and other undoped compounds ($ρ_x

description: Das Buch sollte also vor allem ein Schlaglicht auf eine Dynamik werfen, deren hegemonialer Charakter für den Kapitalismus der Gegenwart keineswegs behauptet wurde. Ich habe vielmehr sehr klar etwa von einem »Akkumulationsregime in the making« geschrieben, einer expansiven Dynamik, deren Logik und Effekte ich theoriebildend erkunden wollte. Der digitale Kapitalismus ist einstweilen ein Kapitalismus im Kapitalismus – so wie es einst auch der industrielle Kapitalismus war. Das Buch liefert eine Möglichkeit darüber nachzudenken, wie der Kapitalismus aussähe, wenn das digitale Produktionsmodell dominant würde – wie es die empirische Lage will, existiert mit dem kommerziellen Internet ein Feld, das der angestellten Theoriebildung sehr genau entspricht.

description: Wie kann die Objektivität der Sozialwissenschaften gewährleistet werden? Max Webers Methodenlehre beantwortet diese Frage im Widerspruch zu der philosophischen Tradition seit Platon und Aristoteles nicht über die Konstruktion von wahren Konzepten, sondern über die logisch konsistente Herleitung einer Interpretation aus willkürlich gewählten nicht-wahren Idealtypen. Webers Lösung ist zweifellos eine notwendige Voraussetzung für eine objektive Sozialwissenschaft, jedoch keine hinreichende Bedingung. Falsche Interpretationsschemata können mit diesem Kriterium nicht ausgeschlossen werden. Karl Poppers Kritischer Rationalismus kann als eine Erweiterung von Max Webers Wissenschaftslehre angesehen werden. Auch wenn generelle Sätze nicht verifiziert werden können, so können sie doch an der Realität scheitern, und somit falsifiziert werden. Dies ist aber nur möglich, wenn auch die Motive der Akteure in den konkreten Situationen verifiziert werden können. Dies wurde von Alfred Schütz gefordert. Die Interpretation der Motive der Akteure durch den Wissenschaftler kann und muss überprüft werden, wenn wir uns der Wahrheit annähern wollen.





How can we guarantee the objectivity of the social sciences? Max Weber’s methodology answers this question in contradiction to the philosophical tradition, since Plato and Aristotle, not through the construction of true concepts, but through the logical deduction of an interpretation out of arbitrary and untrue ideal types. Weber’s solution is unquestionably a necessary prerequisite for an objective social science, but it is not a sufficient condition. False schemes of interpretation cannot be excluded with this criterium. Karl Popper’s critical rationalism could be regarded as an extension of Max Weber’s methodology. Even if general sentences cannot be verified, it is nevertheless possible that they fail the test against reality and therefore can be falsified. This is, however, only possible, if the motives of the actors in the concrete situation can be verified. Alfred Schutz demanded this. The researcher’s inter- pretation of the actor’s motives can and has to be tested, if we want to get closer to the truth.

description: Quantum-enhanced measurements hold the promise to improve high-precision sensing ranging from the definition of time standards to the determination of fundamental constants of nature. However, quantum sensors lose their sensitivity in the presence of noise. To protect them, the use of quantum error correcting codes has been proposed. Trapped ions are an excellent technological platform for both quantum sensing and quantum error correction. Here we present a quantum error correction scheme that harnesses dissipation to stabilize a trapped-ion qubit. In our approach, always-on couplings to an engineered environment protect the qubit against spin- or phase flips. Our dissipative error correction scheme operates in a fully autonomous manner without the need to perform measurements or feedback operations. We show that the resulting enhanced coherence time translates into a significantly enhanced precision for quantum measurements. Our work constitutes a stepping stone towards the paradigm of self-correcting quantum information processing.

description: We published this poseter at GA4GH 9th Plenary Meeting (2021). Nanbyo (難病) is rare and intractable diseases in Japan, which is covered by the medical expense subsidy systems. The Ministry of Health, Labour, and Welfare has published official documents about covered diseases written in Japanese. However
 • Hard to know covered diseases and subtypes by scrutinizing official documents
 • No established correspondence between Nanbyo and diseases in other databases →Difficult to get the latest knowledge and share Japanese medical data internationally Therefore, we constructed • Nanbyo Disease Ontology (NANDO), a machine-readable dictionary • NanbyoData, a portal website to the medical information on Nanbyo
