description: We consider the geometric phase and quantum tunneling in vicinity of diabolic and exceptional points. We show that the geometric phase associated with the degeneracy points is defined by the flux of complex magnetic monopole. In weak-coupling limit the leading contribution to the real part of geometric phase is given by the flux of the Dirac monopole plus quadrupole term, and the expansion for its imaginary part starts with the dipolelike field. For a two-level system governed by the generic non-Hermitian Hamiltonian, we derive a formula to compute the non-adiabatic complex geometric phase by integral over the complex Bloch sphere. We apply our results to to study a two-level dissipative system driven by periodic electromagnetic field and show that in the vicinity of the exceptional point the complex geometric phase behaves as step-like function. Studying tunneling process near and at exceptional point, we find two different regimes: coherent and incoherent. The coherent regime is characterized by the Rabi oscillations and one-sheeted hyperbolic monopole emerges in this region of the parameters. In turn with the incoherent regime the two-sheeted hyperbolic monopole is associated. The exceptional point is the critical point of the system where the topological transition occurs and both of the regimes yield the quadratic dependence on time. We show that the dissipation brings into existence of pulses in the complex geometric phase and the pulses are disappeared when dissipation dies out. Such a strong coupling effect of the environment is beyond of the conventional adiabatic treatment of the Berry phase.

The U.S. solar industry represented a $11.5 billion market in 2012; more than 300,000 systems are in place. With new and more creative financing options, the market could grow even faster and be larger. A working group launched by the Energy Department through its National Renewable Energy Laboratory aims to lower the cost of capital for solar projects by standardizing contracts so that contractual elements like lease payments can be bundled and traded as investment products.

The usual smart grid vision implies a huge increase in the number of entities that will communicate and interact in both the distribution systems and bulk power operation. This requires new methods of management and system operation. But, we need not start from scratch. Tools developed to run competitive wholesale electricity systems provide useful models.

description: We prove a generalization of a theorem of Borel-Harish-Chandra on closed orbits of linear actions of reductive groups. Consider a real reductive algebraic group $G$ acting linearly and rationally on a real vector space $V$. $G$ can be viewed as the real points of a complex reductive group $G^\mathbb C$ which acts on $V^\mathbb C := V \otimes \mathbb C$. Borel-Harish-Chandra show that $G^\mathbb C \cdot v \cap V$ is a finite union of $G$-orbits; moreover, $G^\mathbb C \cdot v$ is closed if and only if $G\cdot v$ is closed. We show that the same result holds not just for closed orbits but for the so-called distinguished orbits. An orbit is called distinguished if it contains a critical point of the norm squared of the moment map on projective space. Our main result compares the complex and real settings to show $G\cdot v$ is distinguished if and only if $G^\mathbb C \cdot v$ is distinguished. In addition, we show that if an orbit is distinguished, then under the negative gradient flow of the norm squared of the moment map the entire $G$-orbit collapses to a single $K$-orbit. This result holds in both the complex and real settings. We finish with some applications to the study of the left-invariant geometry of Lie groups.

description: We report extensive numerical simulations of different models of 2D polymer rings with internal elasticity. We monitor the dynamical behavior of the rings as a function of the packing fraction, to address the effects of particle deformation on the collective response of the system. In particular, we compare three different models: (i) a recently investigated model [Gnan \& Zaccarelli, Nat. Phys. 15, 683 (2019)], where an inner hertzian field providing the internal elasticity acts on the monomers of the ring, (ii) the same model where the effect of such a field on the center of mass is balanced by opposite forces and (iii) a semi-flexible model where an angular potential between adjacent monomers induces strong particle deformations. By analyzing the dynamics of the three models, we find that, in all cases, there exists a direct link between the system fragility and particle asphericity. Among the three, only the first model displays anomalous dynamics in the form of a super-diffusive behavior of the mean squared displacement and of a compressed exponential relaxation of the density auto-correlation function. We show that this is due to the combination of internal elasticity and the out-of-equilibrium force self-generated by each ring, both of which are necessary ingredients to induce such peculiar behavior often observed in experiments of colloidal gels. These findings reinforce the role of particle deformation, connected to internal elasticity, in driving the dynamical response of dense soft particles.

description: Topological Weyl semimetals have been attracting broad interest. Recently, a new type of Weyl point with topological charge of $4$, termed as charge-4 Weyl point (C-4 WP), was proposed in spinless systems. Here, we show the minimum symmetry requirement for C-4 WP is point group $T$ together with ${\cal T}$ symmetry or point group $O$. We establish a minimum tight-binding model for C-4 WP on a cubic lattice with time-reversal symmetry and without spin-orbit coupling effect. This lattice model is a two-band one, ontaining only one pair of C-4 WPs with opposite chirality around Fermi level. Based on both the low-energy effective Hamiltonian and the minimum lattice model, we investigate the electronic, optical and magnetic properties of C-4 WP. Several chirality-dependent properties are revealed, such as chiral Landau bands, quantized circular photogalvanic effect and quadruple-helicoid surface arc states. Furthermore, we predict that under symmetry breaking, various exotic topological phases can evolve out of C-4 WPs. Our work not only reveals several interesting phenomena associate to C-4 WPs, but also provides a simple and ideal lattice model of C-4 WP, which will be helpful for the subsequent study on C-4 WPs.
Soviet-American computer trade : a facet of international interdependence

Publisher: name: University of British Columbia
Year: 2010

description: International politics is now characterized by international interdependence. This fact is both the cause and effect of increased transnational and transgovernmental contacts, arising from the. size and complexity of modern governments. Traditional concerns about military security resulted in theories of international politics which focussed primarily on the potential for war between sovereign states and relegated issues of trade, economics, communications and the like to the status of "low politics". The reality of world politics today requires the analyst to reassess the role of economic factors in international interaction. Military force is an unwieldy or inappropriate tool for many vital issues in the contemporary worlds Computer trade is one such issue. The annual value of trade in computing equipment is approximately US$10 billion, and is expected to increase manyfold in the near future; This paper focusses on computer trade between two states which the traditional theory posits as mortal enemies. The importance of computers to a modern society makes computer trade between adversary nations a controversial subjects. The emphasis of traditional theory on military security is an inadequate perspective from which to assess the effects of computer trade; therefore, the international interdependence paradigm of Keohane and Nye is used for the basis of the political analysis presented in this paper. A chapter on computer software is presented for the reader who is not knowledgable about computers. Hopefully, the reader will understand more about how computers work, about the amount of thought and labor required to build and use computers, and why software and hardware can be considered seperately. The last point is considered especially important for the future of relations between the United States and the Union of Soviet Socialist Republics.

description: We tested the effectiveness on learning of hands-on, night-time laboratories that challenged student misconceptions in a non-major introductory astronomy class at Rensselaer Polytechnic Institute. We present a new assessment examination used to assess learning in this study. We were able to increase learning, at the 8.0 sigma level, on one of the moon phase objectives that was addressed in a cloudy night activity. There is weak evidence of some improvement on a broader range of learning objectives. We show evidence that the overall achievement levels of the four sections of the class is correlated with the amount of clear whether the sections had for observing, even though the learning objectives were addressed primarily in activities that did not require clear skies. This last result should be confirmed with future studies. We describe our first attempt to cycle the students through different activity stations in an attempt to handle 18 students at a time in the laboratories, and lessons learned from this.

While opinions may differ about whether there is a single "right size" for smart grid demonstration projects, most will agree that a village is too small and countries too large to produce meaningful results. University campuses and communities represent an appealing intermediate scale, with enough diversity to put claimed benefits and costs to the test, as well as the intellectual resources to devise innovative approaches. An ambitious program at the University of Minnesota is showing how this can be done.

Koide, Phys. Rev. E75, 060103(R) (2007)]. This is an extension of the Green-Kubo-Nakano (GKN) formula to the case of non-Newtonian fluids, which is the essential factor to preserve the relativistic causality in relativistic dissipative hydrodynamics. This formula is the generalization of the GKN formula in the sense that it can reproduce the GKN formula in a certain limit. In this work, we extend the previous work so as to apply to more general situations.

Considering ‘What Might Be’: Reflections on a Qualitative Study of Academic Search
Creators: name: Krueger, Stephanie
Publisher: name: Young Information Scientist
Year: 2018

description: Objective — To critically describe and evaluate an exploratory research project conducted by the author from 2012-2016. The project examined the academic search patterns of six scientists in four geographical locations who were observed using several qualitative methods, including visual ethnographic techniques. Methods — This reflexive discussion, in case study form, provides insight into decision making about techniques researchers can use to observe people’s interactions within networked environments. It also provides a glimpse into the real-world service design process at a science, technology, engineering, and mathematics (STEM) library. Results — Touching only briefly on theory, the article highlights how visual ethnographic techniques are useful, as an alternative to log or trace data, for observing interactions of individuals within the global networked academic environment (GNAE). Screenshots taken by research participants for this project were rich data sources and provided ‘snapshots’ of how scientists in the study conducted academic search in real-world settings. Conclusions — While findings from the original research project cannot be used to make theoretical generalizations because of the small, non-random study cohort, the study — perhaps paradoxically — enabled the creation of popular services for early career researchers in a real-world setting. This paradox raises provocative questions about goal-setting in library and information science (LIS) research and ties between theory and practice. Archived in E-LIS

We study the variety of (and large magnitude) phases that the electronic states can acquire when a uniform time-dependent electric field carries the electrons around one or more Dirac points in a non-concentric fashion. An experimentally accessible determination of excess Berry phases is proposed involving the Zitterbewegung of electronic current near an orthogonality point in adiabatic motion.

Developers are encouraged to update any outdated dependency to remain safe from potential threats of vulnerabilities. In this study, we present an approach to aid developers show whether or not a vulnerable code is reachable for JavaScript projects. Our prototype, SōjiTantei, is evaluated in two ways (i) the accuracy when compared to a manual approach and (ii) a larger-scale analysis of 780 clients from 78 security vulnerability cases. The first evaluation shows that SōjiTantei has a high accuracy of 83.3%, with a speed of less than a second analysis per client. The second evaluation reveals that 68 out of the studied 78 vulnerabilities reported having at least one clean client. The study proves that automation is promising with the potential for further improvement.

description: In recent work we presented the first results of global general relativistic magnetohydrodynamic (GRMHD) simulations of tilted (or misaligned) accretion disks around rotating black holes. The simulated tilted disks showed dramatic differences from comparable untilted disks, such as asymmetrical accretion onto the hole through opposing "plunging streams" and global precession of the disk powered by a torque provided by the black hole. However, those simulations used a traditional spherical-polar grid that was purposefully underresolved along the pole, which prevented us from assessing the behavior of any jets that may have been associated with the tilted disks. To address this shortcoming we have added a block-structured "cubed-sphere" grid option to the Cosmos++ GRMHD code, which will allow us to simultaneously resolve the disk and polar regions. Here we present our implementation of this grid and the results of a small suite of validation tests intended to demonstrate that the new grid performs as expected. The most important test in this work is a comparison of identical tilted disks, one evolved using our spherical-polar grid and the other with the cubed-sphere grid. We also demonstrate an interesting dependence of the early-time evolution of our disks on their orientation with respect to the grid alignment. This dependence arises from the differing treatment of current sheets within the disks, especially whether they are aligned with symmetry planes of the grid or not.

description: While today’s Indonesian democratic government remains committed to the New Order orthodoxy about the mass killings of 1965, new counter-narratives challenging official history are emerging in the new media. Applying mixed-methods and multi-sited ethnography, this study aims to extend our collaborative understanding of the most recent developments in this situation by identifying multiple online interpersonal stories, deliberations, and debates related to the case as well as offline field studies in Java and Bali. Practically and theoretically, we ask how the tragedy of the 1965 killings is contested in the new media and how social memory plays out in this contestation. The study finds that new media potentially act as emancipatory sites channeling and liberating the voices of those that the nation has stigmatized as ‘objectively guilty’. We argue that the arena of contestation is threefold: individual, public vs. state narrative, and theoretical. As such, the transborder space of the new media strongly mediates corrective new voices to fill missing gaps in the convoluted history of this central event of modern Indonesian history.

description: We analyze the moduli space of the low-energy limit of 3-dimensional N=3 Maxwell-Chern-Simons theories described by circular quiver diagrams, as for 4-dimensional elliptic models. We define the theories by using D3-NS5-(k,1)5-brane systems with an arbitrary number of fivebranes. The supersymmetry is expected to be enhanced to N=4 in the low-energy limit. We show that the Higgs branch, in which all bifundamental scalar fields develop vacuum expectation values, is an abelian orbifold of C^4. We confirm that the same geometry is obtained as an M-theory dual of the brane system. We also consider theories realized by introducing more than two kinds of fivebranes, and obtain nontoric fourfolds as moduli spaces.

description: Crowdsourced live video streaming (livecast) services such as Facebook Live, YouNow, Douyu and Twitch are gaining more momentum recently. Allocating the limited resources in a cost-effective manner while maximizing the Quality of Service (QoS) through real-time delivery and the provision of the appropriate representations for all viewers is a challenging problem. In our paper, we introduce a machine-learning based predictive resource allocation framework for geo-distributed cloud sites, considering the delay and quality constraints to guarantee the maximum QoS for viewers and the minimum cost for content providers. First, we present an offline optimization that decides the required transcoding resources in distributed regions near the viewers with a trade-off between the QoS and the overall cost. Second, we use machine learning to build forecasting models that proactively predict the approximate transcoding resources to be reserved at each cloud site ahead of time. Finally, we develop a Greedy Nearest and Cheapest algorithm (GNCA) to perform the resource allocation of real-time broadcasted videos on the rented resources. Extensive simulations have shown that GNCA outperforms the state-of-the art resource allocation approaches for crowdsourced live streaming by achieving more than 20% gain in terms of system cost while serving the viewers with relatively lower latency.

description: We construct new theories of electroweak symmetry breaking that employ a combination of supersymmetry and discrete symmetries to stabilize the weak scale up to and beyond the energies probed by the LHC. These models exhibit conventional supersymmetric spectra but the fermion-sfermion-gaugino vertices are absent. This closes many conventional decay channels, thereby allowing several superpartners to be stable on collider time scales. This opens the door to the possibility of directly observing R-hadrons and three flavors of sleptons inside the LHC detectors.

Excluding migrant labor from the Malaysian bioeconomy: Working and living conditions of migrant workers in the palm oil sector in Sabah
Creators: name: Puder, Janina
Publisher: name: Austrian Journal of South-East Asian Studies
Year: 2019

description: In 2012, Malaysia launched its bioeconomy program, with the palm oil sector as one of the main pillars. In focusing on the societal processes that accompany the Malaysian plans to establish a bioeconomy, it is of special interest to understand which occupation groups in the palm oil sector are included and which are excluded from the socio-economic targets of the program. Research on the bioeconomy, as well as a green economy more broadly, often neglect the possible effects of green economy models on labor markets. I argue that low-skilled migrant workers employed in the Malaysian palm oil sector are structurally excluded from the national goal of enhancing the living and working conditions of the population by transforming into a bioeconomy. This exclusion intersects with a specific precarity caused by the socio-economic status of low-skilled migrant workers. The article shows that Malaysia’s bioeconomy program reinforces the precarity of this group of workers, expressed in the lack of perspectives for upward mobility, their discrimination on the labor market, and in social barriers preventing them from further training. The findings presented are based on expert interviews and semi-structured qualitative interviews with workers from Sabah.

It was shown almost fifty years ago how to apply sparsity programming techniques to power flow analysis, and several decades later ways were found to adapt those techniques to vector processing. But this kind of processing for security analysis required expensive supercomputers. Now, thanks to inexpensive processing cards spun off from those used in computerized gaming, we are on our way to being able to process large numbers of AC power flow cases on power system models and identify worrisome cases.
The performance of discriminant analysis procedures under non-optimal conditions
Creators: name: Lind, John Charles
Publisher: name: University of British Columbia
Year: 2010

description: The performance of four discriminant analysis procedures for the classification of observations from unknown populations was examined by Monte Carlo methods. The procedures examined were the Fisher linear discriminant function, the quadratic discriminant function, a polynomial discriminant function and a linear procedure designed for use in situations where covariance matrices are unequal. Each procedure was observed under conditions of unequal sample sizes, unequal covariance matrices, and in conditions where the samples were drawn from populations that did not have a multivariate normal distribution. When the population covariance matrices were equal, or not greatly different, the quadratic discriminant function performed similarly or marginally better than the linear procedures. In all cases the polynomial discriminant function demonstrated the poorest quadratic discriminant function performed much better than the other procedures. All of the procedures were greatly affected by non-normality and tended to make many more errors in the classification of one group than the other, suggesting that data be standardized when non-normality is suspected.

description: Type Ia supernovae (SNe Ia) occur in both old, passive galaxies and active, star-forming galaxies. This fact, coupled with the strong dependence of SN Ia rate on star formation rate, suggests that SNe Ia form from stars with a wide range of ages. Here we show that the rate of SN Ia explosions is about 1% of the stellar death rate, independent of star formation history. The dependence of SN Ia rate on star formation rate implies a delay time distribution proportional to t^{-0.5+-0.2}. The single degenerate channel for SNe Ia can be made to match the observed SN Ia rate -- SFR relation, but only if white dwarfs are converted to SNe Ia with uniform efficiency of ~1%, independent of mass. Since low-mass progenitors are expected to have lower conversion efficiencies than high mass progenitors, we conclude that some other progenitor scenario must be invoked to explain some, or perhaps all, SNe Ia.

Recalling hydraulic despotism: Hun Sen’s Cambodia and the return of strict authoritarianism
Creators: name: Blake, David J. H.

description: Mirroring trends elsewhere in Southeast Asia, Cambodia has witnessed a pronounced shift towards stricter authoritarianism over recent years. The state appears more firmly ruled by prime minister Hun Sen than at any time during the past three decades, while the de facto status of the Cambodian People’s Party (CPP) more closely resembles the single party regimes of neighboring states. One of the major tools of political control and expansion of authority employed by the hierarchical CPP network is the construction of major infrastructure projects, most notably hydropower dams and irrigation schemes. This article focuses attention on the hydraulic infrastructure aspects of exacting political authority and social control by the elite over the nation, drawing upon Wittfogelian perspectives for a conceptual framework. It maintains that Cambodia increasingly represents a modern variant of a hydraulic society, but primarily functions as a satellite hydraulic state of China. The growing influence of China over Cambodia’s hydraulic development has helped elevate Hun Sen to resemble a neo-classic hydraulic despot. Hydraulic society concepts help provide partial understanding of contemporary power relations and party-state ascendency, including the longevity and resilience of Hun Sen’s supremacy.

description: This study reviews the rising household debt and nonfinancial corporation debt in Vietnam, a socialist-oriented, lower middle-income emerging economy. Vietnam has made huge strides in economic growth within three decades of reforms, lifting millions of people out of poverty thanks to better access to credit. At the same time, there are lending and borrowing practices that signal troubles ahead. Based on a thorough examination of the theoretical literature on indebtedness, the study sets out to identify the drivers of borrowing and over-borrowing in Vietnam in recent years. Particularly, the abundant financial and physical resources have given rise to consumerism and the boom of the super-rich. These are two of the four factors that have shifted Vietnamese culture from one that traditionally condemned debt as a vice to one that now tolerates indebtedness. The other two factors can be found at the corporate level where there is an over-reliance on debt financing and rampant rent-seeking. Here, a kind of ‘resource curse’ threatens sustainable corporate growth – businesses rely too much on borrowing to fuel their operations, but in fact are overlooking the innovation factor. The new politics of debt, we suggest, have created a toxically pro-consumption, debt-tolerant society.

Newsletter
Demonstration projects in the UK are evaluating the use of phasor measurement units in wind generation control and microgrid management. But the potential of PMUs in distribution systems does not end there. They also will find application in phase balancing using three-phase measurement, improved state estimation, locating faults in distribution systems with generation, short circuit capacity identification, and improved modelling and efficient reinforcement planning, among other things.

description: Question answering over knowledge graphs (KG-QA) is a vital topic in IR. Questions with temporal intent are a special class of practical importance, but have not received much attention in research. This work presents EXAQT, the first end-to-end system for answering complex temporal questions that have multiple entities and predicates, and associated temporal conditions. EXAQT answers natural language questions over KGs in two stages, one geared towards high recall, the other towards precision at top ranks. The first step computes question-relevant compact subgraphs within the KG, and judiciously enhances them with pertinent temporal facts, using Group Steiner Trees and fine-tuned BERT models. The second step constructs relational graph convolutional networks (R-GCNs) from the first step's output, and enhances the R-GCNs with time-aware entity embeddings and attention over temporal relations. We evaluate EXAQT on TimeQuestions, a large dataset of 16k temporal questions we compiled from a variety of general purpose KG-QA benchmarks. Results show that EXAQT outperforms three state-of-the-art systems for answering complex questions over KGs, thereby justifying specialized treatment of temporal QA.

description: The BABAR Silicon Vertex Tracker (SVT) is a five-layer double-sided silicon detector designed to provide precise measurements of the position and direction of primary tracks, and to fully reconstruct low-momentum tracks produced in e+e- collisions at the PEP-II asymmetric collider at Stanford Linear Accelerator Center. This paper describes the design, implementation, performance, and validation of the local alignment procedure used to determine the relative positions and orientations of the 340 SVT wafers. This procedure uses a tuned mix of in-situ experimental data and complementary lab-bench measurements to control systematic distortions. Wafer positions and orientations are determined by minimizing a chisquared computed using these data for each wafer individually, iterating to account for between-wafer correlations. A correction for aplanar distortions of the silicon wafers is measured and applied. The net effect of residual mis-alignments on relevant physical variables is evaluated in special control samples. The BABAR data-sample collected between November 1999 and April 2008 is used in the study of the SVT stability.

description: We calculate the full $I-V$ characteristics at vanishing temperature in the self-dual interacting resonant level model in two ways. The first uses careful time dependent DMRG with large number of states per block and a representation of the reservoirs as leads subjected to a chemical potential. The other is based on integrability in the continuum limit, and generalizes early work of Fendley Ludwig Saleur on the boundary sine-Gordon model. The two approaches are in excellent agreement, and uncover among other things a power law decay of the current at large voltages when $U>0$.
