Unsupervised Residual Vector Analysis for Mesh Optimization
Creators: name: Zandsalimy, Mohammad
name: Ollivier-Gooch, Carl
Publisher: name: AIAA
Year: 2024

description: This work prototypes novel methods to enhance the efficiency of a previous CFD stability improvement approach. The feasibility of residual vector analysis for unstable solution mode identification is studied. Unsupervised machine learning models in the form of outlier detectors are used to identify anomalous vector elements. A novel method is presented to construct synthetic vectors that resemble unstable eigenvectors. Synthetic vectors are used to find vertices for modification and calculate the vertex movement direction and magnitude. The residual vector helps substantially in reducing the computational cost of the optimization algorithm. In comparison to the full eigenanalysis of the Jacobian matrix, residual vector analysis requires much fewer computational resources. This methodology is used for the first time for the stability improvement of finite-volume simulations. It is shown that using residual vector analysis for the identification of the unstable solution modes and problematic cells in the mesh has a similar stabilization performance to using the right eigenvectors.
An Abstract Interface to Higher Spin Gauge Field Theory

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: A comprehensive approach to the theory of higher spin gauge fields is proposed. By explicitly separating out details of implementation from general principles, it becomes possible to focus on the bare minimum of requirements that such a theory must satisfy. The abstraction is based on a survey of the progress that has been achieved since relativistic wave equations for higher spin fields were first considered in the nineteen thirties. As a byproduct, a formalism is obtained that is abstract enough to describe a wide class of classical field theories. The formalism, viewed as syntax, can then be semantically mapped to a category of homotopy Lie algebras, thus showing that the theory in some sense exists, at least as an abstract mathematical structure. Still, a concrete physics-like, implementation remains to be constructed. Lacking deep physical insight into the problem, an implementation in terms of generalized vertex operators is set up within which a brute force iterative determination of the first few orders in the interaction can be attempted.

description: Recently, the use of neural quantum states for describing the ground state of many- and few-body problems has been gaining popularity because of their high expressivity and ability to handle intractably large Hilbert spaces. In particular, methods based on variational Monte Carlo have proven to be successful in describing the physics of bosonic systems such as the Bose-Hubbard (BH) model. However, this technique has not been systematically tested on the parameter space of the BH model, particularly at the boundary between the Mott insulator and superfluid phases. In this work, we evaluate the capabilities of variational Monte Carlo with a trial wavefunction given by a Restricted Boltzmann Machine to reproduce the quantum ground state of the BH model on several points of its parameter space. To benchmark the technique, we compare its results to the ground state found through exact diagonalization for small one-dimensional chains. In general, we find that the learned ground state correctly estimates many observables, reproducing to a high degree the phase diagram for the first Mott lobe and part of the second one. However, we find that the technique is challenged whenever the system transitions between excitation manifolds, as the ground state is not learned correctly at these boundaries. We improve the quality of the results produced by the technique by proposing a method to discard noisy probabilities learned in the ground state.

description: Light Higgs bosons (h^0) with a mass below 60 GeV may have escaped detection at LEP due to a suppressed cross-section for e^+e^-\to Zh^0. Their discovery is also problematic in standard search channels at the Tevatron Run II and LHC. Such a h^0 can arise in the two Higgs doublet model (2HDM) and in the Minimal Supersymmetric Standard Model (MSSM) with explicit CP violating phases. We propose the mechanism p\bar p \to H^\pm h^0 which offers cross-sections of up to 500 fb in the 2HDM, or up to 100 fb in the MSSM. The possibility of a large branching ratio for H^\pm\to h^0W^\pm would give rise to the non-standard signature h^0h^0W^\pm which might facilitate detection.

description: The University of British Columbia Library, The University of Alberta Library, and Simon Fraser University Library are collaborating with a local open-source developer of Digital Collections and Archival software platforms in order to meet their respective needs for new digital repository initiatives at all three sites. The projects present an intersection of both open and community source development Although each institution has some local development expertise to take full advantage of open-source software, the collaboration remains novel in respect to the funding model allowing each institution to contribute their own site-specific requirements and benefit from the resulting common architecture. The partners will discuss their experiences and expected outcome from this collaboration, touching briefly on their own implementation plans. Simon Fraser University is developing a Research Data Repository (RaDar), The University of British Columbia is creating a digital preservation program which includes integration with cIRcle and the University of Alberta continues to develop the Canadian Polar Data Network along with other collaborations.

description: We apply the point form of relativistic quantum mechanics to develop a Poincare invariant coupled-channel formalism for two-particle systems interacting via one-particle exchange. This approach takes the exchange particle explicitly into account and leads to a generalized eigenvalue equation for the Bakamjian-Thomas type mass operator of the system. The coupling of the exchange particle is derived from quantum field theory. As an illustrative example we consider vector mesons within the chiral constituent quark model in which the hyperfine interaction between the confined quark-antiquark pair is generated by Goldstone-boson exchange. We study the effect of retardation in the Goldstone-boson exchange by comparing with the commonly used instantaneous approximation. As a nice physical feature we find that the problem of a too large $ρ$-$ω$ splitting can nearly be avoided by taking the dynamics of the exchange meson explicitly into account.

description: Agricultural Export is regarded as the main axis of economic development, plays a remarkable role in non-Oil export development and currency income. Therefore, reviewing Factors affecting agricultural exports supply seems imperative. In this study, Factors affecting agricultural exports are reviewed using time series analysis and is analyzed with Auto-Regressive Distributed Lag Estimates (ARDL). Data used in this study were collected from various sources including FAO Site, Iranian Central Bank and World Bank for the period of 1970 to 2008. Results indicate that long-term relationship exists between agricultural exports supply and other variables, all variables are significant. World real GDP and exchange rate had positive impact and other factors had negative impact on Iranian exports of agricultural products. In addition, the short-term relationship results indicate that of about 55 percent of short-term deviations were adjusted by long-term equilibrium value of exports.

description: A number of experimental platforms for quantum simulations of disordered quantum matter, from dipolar systems to trapped ions, involve degrees of freedom which are coupled by power-law decaying hoppings or interactions, yet the interplay of disorder and interactions in these systems is far less understood than in their short-ranged counterpart. Here we consider a prototype model of interacting fermions with disordered long-ranged hoppings and interactions, and use the flow equation approach to map out its dynamical phase diagram as a function of hopping and interaction exponents. We demonstrate that the flow equation technique is ideally suited to problems involving long-range couplings due to its ability to accurately simulate very large system sizes. We show that, at large on-site disorder and for short-range interactions, a transition from a delocalized phase to a quasi many-body localized (MBL) phase exists as the hopping range is decreased. This quasi-MBL phase is characterized by intriguing properties such as a set of emergent conserved quantities which decay algebraically with distance. Surprisingly we find that a crossover between delocalized and quasi-MBL phases survives even in the presence of long-range interactions.

description: We theoretically study the trapping time distribution and the efficiency of the excitation energy transport in dendritic systems. Trapping of excitations, created at the periphery of the dendrimer, on a trap located at its core, is used as a probe of the efficiency of the energy transport across the dendrimer. The transport process is treated as incoherent hopping of excitations between nearest-neighbor dendrimer units and is described using a rate equation. We account for radiative and non-radiative decay of the excitations while diffusing across the dendrimer. We derive exact expressions for the Laplace transform of the trapping time distribution and the efficiency of trapping and analyze those for various realizations of the energy bias, number of dendrimer generations, and relative rates for decay and hopping. We show that the essential parameter that governs the trapping efficiency, is the product of the on-site excitation decay rate and the trapping time (mean first passage time) in the absence of decay.

Assuming that the expansion of the BI universe is proportional to the $σ_1^1$ component of the shear tensor, exact solutions for the metric functions, as well as for scalar and spinor fields are obtained. For a non-positive $Λ$ the initially anisotropic space-time becomes isotropic one in the process of expansion, whereas, for $Λ> 0$ an oscillatory mode of expansion of the BI model occurs.

description: This paper investigates the effect of social capital between irrigation canal head-enders and tail-enders on their water allocation problem. In irrigation management, the water allocation problem between head-enders and tail-enders is one of the serious problems. Using unique natural and artefactual field experiment data as well as general household survey data collected by JICA, this study finds that social capital, especially trust toward their tail-enders, has a significantly positive effect on satisfaction with water usage among head-enders. Considering the fact that the incentive structure of irrigation water allocation for head-enders closely resembles that in the dictator and trust games, this finding also supports the validity of experimentally measured social capital. In addition, this study deals with the simultaneity bias between satisfaction level and experimentally measured social capital, and finds that OLS estimators are downward biased, which is consistent with the hypothesis that scarcity of resources enhances social capital.

 Semnostola Diakonoff, 1959: 174. Type species: Semnostola mystica Diakonoff, 1959, by original designation.
 Ancyloides Kuznetzov, 1964: 882. Type species: Eucosmomorpha (Ancyloides) magnifica Kuznetzov, 1964, by original designation, established as subgenus of Eucosmomorpha Obraztsov.
 Diagnosis. Forewing elongate­narrow, often with a dorsal blotch, R 4 and R 5 connate; hindwing with R S and M 1 stalked to about middle, M 3 and CuA 1 closely approximated at base. Male genitalia with valva long; basal cavity large; cucullus small, bearing a terminal pollex; uncus vestigial or absent; sacculus with indistinct or atrophied angle, with variably developed band of long hairs; socii not fused. Female genitalia usually with papilla analis long and narrow; sterigma sclerotized; colliculum present or absent, usually a ring of sclerotization, if present; signa horn­ or thorn­shaped.
 The genus Semnostola is similar to Enarmonia Hübner and Pseudophiaris Obraztsov; all three share a terminal pollex of the valva. Semnostola can be distinguished from Enarmonia by the absence of an uncus, and from Pseudophiaris by its setose socius, the tegumen not concave medially on posterior margin, and its horn­ or thorn­shaped signa.
 Semnostola is distributed in China, Korea, Japan, Vietnam, Burma, and Russia (Far East).

description: Visual programming has the potential of providing novice programmers with a low-code experience to build customized processing pipelines. Existing systems typically require users to build pipelines from scratch, implying that novice users are expected to set up and link appropriate nodes from a blank workspace. In this paper, we introduce InstructPipe, an AI assistant for prototyping machine learning (ML) pipelines with text instructions. We contribute two large language model (LLM) modules and a code interpreter as part of our framework. The LLM modules generate pseudocode for a target pipeline, and the interpreter renders the pipeline in the node-graph editor for further human-AI collaboration. Both technical and user evaluation (N=16) shows that InstructPipe empowers users to streamline their ML pipeline workflow, reduce their learning curve, and leverage open-ended commands to spark innovative ideas.

description: The strongly interacting partonic medium created post ultrarelativistic heavy ion collision experiments exhibits a significant temperature-gradient between the central and peripheral regions of the collisions, which in turn, is capable of inducing an electric field in the medium; a phenomenon known as Seebeck effect. The effect is quantified by the magnitude of the induced electric field per unit temperature-gradient - the Seebeck coefficient ($S$). We study the coefficient, $S$ in the relativistic Boltzmann transport equation in relaxation-time approximation, as a function of temperature ($T$) and chemical potential ($μ$), wherein we find that with current quark masses, the magnitude of $S$ for individual flavours as well as that for the medium as a whole decreases with $T$ and increases with $μ$, with the electric charge of the flavour deciding the sign of $S$. The emergence of a strong magnetic field ($B$) in the non-central collisions at heavy-ion collider experiments motivates us to study the effect of $B$ on Seebeck effect. The strong $B$ affects $S$ in multifold ways, via : a) modification of phase-space due to the dimensional reduction, b) dispersion relation in lowest Landau level (occupation probability), and c) relaxation-time. We find that a strong $B$ not only decreases the magnitudes of $S$'s of individual species, it also flips their signs. This leads to a faster reduction of the magnitude of $S$ of the medium than its counterpart at $B=0$. We then explore how the interactions among partons in perturbative thermal QCD in the quasiparticle framework affect Seebeck effect, where we find that even in strong B, there is no more a flip of the sign of $S$ for individual species and an enhancement of the magnitudes of $S$ of individual species as well as that of the medium, compared to current quark mass description at either $B=0$ or $B \neq 0$.

description: Although the educational function in agriculture is attracting growing attention as a kind of multifunctionality in agriculture, these services are not yet provided as a viable farm product. With regard to establishing a viable market for this service, this paper explores how the educational externality could be internalized by focusing on educational dairy farms in Japan and quantitatively evaluated the attitudes of operators toward establishing a viable service as revealed by a questionnaire survey. First, a conceptual framework was presented to express operators’ orientation toward an economically viable service by incorporating a stepwise internalization process of positive externalities with the help of a social learning network. Then, empirically, factors that determined this orientation, a viable service determinant function, were explored by the ordered logit model. The result showed that, first, the higher the number of visitors to the farm, the more operators were oriented toward a viable service while no connection with ordinary dairy production was shown. Second, social learning was effective for initiating the internalization process. Third, marketing skills became more important for upgrading the internalization level. Consequently, it is important to create opportunities for those farmers who want to provide consumers with educational services to learn a new role for agriculture and to stepwisely establish a new income source.

description: There is evidence that productivity in Australia’s broadacre agriculture (extensive cropping and livestock industries) has been slowing in the past decade. A series of poor seasons has been partly responsible but an econometric analysis of structural changes in the trend of TFP indicates that stagnant public investment in agricultural R&D has also made a significant contribution to this slowdown in TFP. Related econometric analysis of the returns to public investment in agricultural R&D in the broadacre sector confirms that the rate of return to investment remains high. Despite these findings a recent enquiry by Australia’s Productivity Commission into the financing of rural research suggests that the public sector may be ‘crowding out’ private sector investment in agricultural R&D and recommends a reduction in public support. In this paper I briefly review the econometric analyses to date and the trends in TFP and public R&D investment. While I have not been able to conclusively test the ‘crowding out’ hypothesis, there seems to be little empirical evidence to prefer this hypothesis to a more traditional ‘market failure’ hypothesis. Clearly stakeholders in agricultural R&D in Australia have to do a better job in communicating the case for public investment in agricultural R&D. Other developed countries are experiencing the same phenomenon and it may become an issue in the future for developing countries in Asia.

Consider a pair of linear transformations $A:V\to V$ and $A^*:V\to V$ that satisfy both conditions below: (i) There exists a basis for $V$ with respect to which the matrix representing $A$ is diagonal, and the matrix representing $A^*$ is irreducible tridiagonal. (ii) There exists a basis for $V$ with respect to which the matrix representing $A^*$ is diagonal, and the matrix representing $A$ is irreducible tridiagonal. Such a pair is called a Leonard pair on $V$. In this paper we introduce a mild generalization of a Leonard pair called a tridiagonal pair. A Leonard pair is the same thing as a tridiagonal pair such that for each transformation all eigenspaces have dimension one.

Badges to acknowledge open practices
Creators: name: Sallans, Andrew
Publisher: name: Zenodo
Year: 2014

description: Openness is a core value of scientific practice. There is no central authority determining the validity of scientific claims. Accumulation of scientific knowledge proceeds via open communication with the community. Sharing evidence for scientific claims facilitates critique, extension, and application. Despite the importance of open communication for scientific progress, present norms do not provide strong incentives for individual researchers to share data, materials, or their research process. As an example, journals can provide such incentives by acknowledging open practices with badges in publications. Badges do not define good practice; badges certify that a particular practice was followed. This talk will introduce this strategy and the initial three open practices badges specified by the committee of open science community members: Open Data, Open Materials, and Preregistration. It will also include examples of implementation and community reaction.

In the ScxGa1-xN/GaN heterostructure grown in metal rich conditions on GaN-SiC template substrates with Sc contents up to 28 atomic percent, the oxygen concentration is found to be below 1x1019/cm3, with an increase directly correlated with the Scandium content. In the ScxAl1-xN-AlN heterostructure grown in nitrogen rich conditions on AlN-Al2O3 template substrates with Sc contents up to 26 atomic percent, the oxygen concentration is found to be between 1019 to 1021/cm3, again directly correlated with the Sc content. The increased oxygen and carbon arises during the deposition of scandium alloyed layers.

The study was carried out in 3 districts of Hung Yen province from 2006 to 2010. The study results are as follows: first, the land conversion to industrialization has impact on not only the decline of household landholdings but also the changes value of land which are the sources of social conflicts and informal land transfer. Second, in the context of land conversion to industrialization with tiny plots of land, low return from agricultural production and more opportunities of non-farm activities, even when non-farm employment is very profitable, peasant households are not likely to give up their land but maintaining agricultural production for not only their basic and secure livelihood but also for their identity. Third, among the affected peasant groups, the households with non-farm background tend to be in better position in engaging to high - earning activities. They are likely the rich peasants in opposed to the poor group with farming background and lost more than 50% of their agricultural land. This research has showed that the industrialization policies have to deal with the proportion of agricultural land would be transferred for industrialization zones and other measures in order to limit the conflicts as well as the social differentiation in countryside.

description: We carry out lattice simulations of two-color QCD and spectroscopy at finite density with two flavors of rooted-staggered quarks and a diquark source term. As in a previous four-flavor study, for small values of the inverse gauge coupling we observe a Goldstone spectrum which reflects the symmetry-breaking pattern of a Gaussian symplectic chiral random-matrix ensemble (GSE) with Dyson index $β_D=4$, which corresponds to any-color QCD with adjoint quarks in the continuum instead of QC$_2$D wih fundamental quarks. We show that this unphysical behavior occurs only inside of the bulk phase of $SU(2)$ gauge theory, where the density of $Z_2$ monopoles is high. Using an improved gauge action and a somewhat larger inverse coupling to suppress these monopoles, we demonstrate that the continuum Goldstone spectrum of two-color QCD, corresponding to a Gaussian orthogonal ensemble (GOE) with Dyson index $β_D=1$, is recovered also with rooted-staggered quarks once simulations are performed away from the bulk phase. We further demonstrate how this change of random-matrix ensemble is reflected in the distribution of eigenvalues of the Dirac operator. By computing the unfolded level spacings inside and outside of the bulk phase, we demonstrate that, starting with the low-lying eigenmodes which determine the infrared physics, the distribution of eigenmodes continuously changes from the GSE to the GOE one as monopoles are suppressed.

Discovering and accessing Social Science data of East Asian countries: Trends and obstacles
Creators: name: Jungwon Yang
Publisher: name: Zenodo

description: The increasing use of geographic information system (GIS), combined with the wider availability of statistics of census and economic data, has recently opened up new possibilities for more interdisciplinary academic research in social sciences. Social science researchers have become more and more interested in combining geographic analysis and traditional quantitative and statistical methods in order to test hypotheses and present arguments in more effective ways. Yet, discovering, accessing, and using international geospatial data and statistics is still a challenge for researchers: As OECD Global Science Forum report (2013) noted, information about the existence of micro-data and their availability for the re-use is often difficult to find. The language, legal, cultural, and technological obstacles often exacerbate the difficulty to re-use the discovered data. In this paper, I review what kinds of new data on East Asian countries have been recently developed by national statistical agencies, government departments, and academic institutions. Also, what obstacles researchers have encountered in using the data in their research are investigated.

description: The resolution of a conventional telescope used to image visible-light synchrotron radiation is often limited by diffraction effects. To improve resolution, the double-slit interferometer method was developed at KEK and has since become popular around the world. Based on the Van Cittert-Zernike theorem relating transverse source profile to transverse spatial coherence, the particle beam size can be inferred by recording fringe contrast as a function of interferometer slit separation. In this paper, we describe the SPEAR3 double-slit interferometer, develop a theoretical framework for the interferometer and provide experimental results. Of note the double-slit system is 'rotated' about the beam axis to map the dependence of photon beam coherence on angle.

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Single three dimensional polymers confined to a slab, i.e. to the region between two parallel plane walls, are studied by Monte Carlo simulations. They are described by $N$-step walks on a simple cubic lattice confined to the region $1 \le z \le D$. The simulations cover both regions $D << R_F$ and $D >> R_F$ (where $R_F \sim N^ν$ is the Flory radius, with $ν\approx 0.587$), as well as the cross-over region in between. Chain lengths are up to $N=80,000$, slab widths up to D=120. In order to test the analysis program and to check for finite size corrections, we actually studied three different models: (a) Ordinary random walks (mimicking $Θ$-polymers); (b) Self-avoiding walks (SAW); and (c) Domb-Joyce walks with the self-repulsion tuned to the point where finite size corrections for free (unrestricted) chains are minimal. For the simulations we employ the pruned-enriched-Rosenbluth method (PERM) with Markovian anticipation. In addition to the partition sum (which gives us a direct estimate of the forces exerted onto the walls), we measure the density profiles of monomers and of end points transverse to the slab, and the radial extent of the chain parallel to the walls. All scaling laws and some of the universal amplitude ratios are compared to theoretical predictions.

DDI Handbook: Overview and examples of recommended best practices
Creators: name: Wackerow, Joachim
Publisher: name: Zenodo
Year: 2014

description: This session introduces the DDI Handbook Project. Building upon previous efforts at various DDI workshops, the project will produce a collection of best practices on using DDI. These best practice descriptions will be modular with a homogeneous format, allowing reorganization in multiple ways. The primary structure for the collection will be organized in alignment with the DDI Lifecycle. A goal will be to involve the DDI community in producing a shared body of resources for all organizations and individuals using the DDI specification. Best practices will be reviewed by a team of editors and reviewers and published on a dedicated website. The presentation will describe the overall project and some of the specific best practices which will appear in the initial collection. These will include guidelines for archives introducing DDI into their workflow and other institutions already using DDI Codebook and shifting some of their workflow to DDI Lifecycle. Another area will be utilizing DDI for data discovery.

description: Background: Neutron transfer measurements for the $^{18}$O + $^{28}$Si system have shown that the experimental one-neutron and two-neutron transfer cross sections are well reproduced with spectroscopic amplitudes from two different shell model interactions for the Si isotopes: \textit{psdmod} for the two-neutron transfer, and \textit{psdmwkpn} for the one-neutron transfer. Purpose: The origin of this ambiguity can be related to a more complex mechanism in the one-neutron transfer that requires the unpairing of neutrons prior to its transfer in the ($^{18}$O,$^{17}$O) reaction. Studying a nucleus where this characteristic is absent ($^{13}$C) should help to elucidate this question. Method: One-neutron transfer cross sections were measured for the $^{13}$C + $^{28}$Si at E$_{lab}$ = 30, and 34 MeV, and compared with coupled reaction channel calculations using spectroscopic amplitudes derived from the \textit{psdmod} and \textit{psdmwkpn} shell model interactions. Results: The spectroscopic amplitudes from the \textit{psdmod} interaction for the relevant states in $^{29}$Si provide a good description of the experimental data and the corresponding values agree with previous estimates obtained from the (d,p) reaction. Conclusions: The experimental data for the one-neutron transfer to $^{28}$Si induced by ($^{13}$C,$^{12}$C) reaction is well reproduced using spectroscopic amplitudes from the \textit{psdmod}.

4D beyond-cohomology topological phase protected by $C_2$ symmetry and its boundary theories

description: We study bosonic symmetry protected topological (SPT) phases with $C_{2}$ rotational symmetry in four spatial dimensions which is not captured by the group cohomology classification. By using the topological crystal approach, we show that the topological crystalline state of this SPT phase is given by placing an $E_{8}$ state on the two dimensional rotational invariant plane, which provides a simple physical picture of this phase. Based on this understanding, we show that a variant of QED4 with charge-1 and charge-3 Dirac fermions is a field theoretical description of the three dimensional boundary. We also discuss the connection to symmetric gapped boundary with topological order and its anomaly signature.
