description: Generalizing toric varieties, we introduce toric Deligne-Mumford stacks which correspond to combinatorial data. The main result in this paper is an explicit calculation of the orbifold Chow ring of a toric Deligne-Mumford stack. As an application, we prove that the orbifold Chow ring of the toric Deligne-Mumford stack associated to a simplicial toric variety is a flat deformation of (but is not necessarily isomorphic to) the Chow ring of a crepant resolution.

description: A series of novel 1,2-benzothiazine based quaternary ammonium salts were successfully prepared through different organic transformations. Products of all transformations and final salts were separated out and purified. The product yields were good to excellent for all transformations. Resultant 1,2-benzothiazine based cationic amphiphilic systems were stabilized using different counter anions. All final products were confirmed by 1HNMR and 13CNMR analyses. 1,2-benzothiazine based quaternary ammonium salts have a potential to be employed as a phase transfer catalyst for various reactions in future.

description: The abundance of alpha-process elements such as magnesium and carbon relative to iron measured from the broad emission lines of QSOs can serve as a diagnostic of the star formation and chemical enrichment histories of their host galaxies. We investigate the relationship between Fe/Mg and Fe/C abundance ratios and the resulting Fe II / Mg II 2800A and Fe II / 1900A-blend flux ratios, both of which have been measured in QSOs out to redshifts of approximately six. Using a galactic chemical evolution model based on a starburst in a giant elliptical galaxy, we find that these flux ratios are good tracers of the chemical enrichment of the nuclei. However, the values of these ratios measured in objects at redshifts of approximately six suggest that iron enrichment has occurred more rapidly in these objects than predicted by the assumed elliptical starburst model, under currently favored cosmologies.

description: Resource and environmental planning cannot be separated. Planning for resource use without recognition of the environmental goals or objectives of society may result in resource allocations which are socially suboptimal. Similarly, planning for environmental quality without assessing the suitability, availability and productivity of the resource base may impair economic efficiency and the distribution of output.
Air photo digitization takes flight: Niagara's journey from paper to points to digital mosaics
Creators: name: Janzen, Sharon
Publisher: name: Zenodo
Year: 2018

description: As snapshots in time, historical air photos capture undisputed changes in our landscape. This story begins with a century old air photo, tattered and torn, and begs for preservation. Thousands of air photos later, these have transformed from 9x9 inch contact prints to seamless digital mosaic datasets spanning the Niagara region. Digitization is not only a hot topic for data creation but also an innovative approach to preserving our local heritage resources. Elements of the process include scanning, mosaicking, geo-referencing, and publishing to online mapping environments. Many of these processes foster a collaborative workflow as thousands of traditional resources are scanned for archiving and repurposed into far-reaching digital exhibits. The Niagara Air Photo Index offers a point-and-click environment for researchers to gather information, access individual air photo images, and browse regional mosaics that span 50 years of imagery. What was once a fragile historical document has become a cutting-edge web resource with many stories to tell! This presentation will describe the workflow, processes, and resurfaced stories that this creative initiative has fostered.

Environmental Economics and Policy

description: What burdens should have to borne by residents of a jurisdiction adversely impacted by a project or policy that generally benefits residents elsewhere? The premise that citizens and officials of impacted communities should have available the necessary tools to mitigate adverse impacts, should they choose to do so, is contradicted by the observation that local capacity problems in effectively utilizing available impact mitigation options are compounded by the introduction of environmental risk considerations associated with low probability, high consequence occurrences. Analyzing four possible decision scenarios under conditions of uncertainty, the question of who would bear the cost of each kind of decision error was found to be at the root of the repository siting problem. Given "there is no risk-free environment," national policy must allocate risk by choosing between acceptance for society the Type I error and rejecting siting everywhere, or proceeding with siting somewhere and imposing exposure to the Type II error upon the impacted community. The latter choice would present two mitigation issues. One, under what conditions should a community accept exposure failure to predict a catastrophic impact outcome? Two, what institutional designs can more effectively link exposure to consequences of a low probability, high consequence occurrence with reduced probability of such an occurrence?

description: Recent observational data suggests a high compacticity (the quotient M/R) of some "neutron" stars. Motivated by these works we revisit models based on quark-diquark degrees of freedom and address the question of whether that matter is stable against diquark disassembling and hadronization within the different models. We find that equations of state modeled as effective $λϕ^{4}$ theories do not generally produce stable self-bound matter and are not suitable for constructing very compact star models, that is the matter would decay into neutron matter. We also discuss some insights obtained by including hard sphere terms in the equation of state to model repulsive interactions. We finally compare the resulting equations of state with previous models and emphasize the role of the boundary conditions at the surface of compact self-bound stars, features of a possible normal crust of the latter and related topics.

Omni-family Housing : Adaptable housing density for diverse ways of living
Creators: name: Reid, Christopher
Publisher: name: The University of British Columbia
Year: 2023

description: Ongoing trends of urbanization are increasing the demand for housing in many of North America’s major cities, causing parallel increases in housing prices and driving what many have called an ‘affordability crisis’ in urban housing markets. Meeting this increased demand for housing and addressing affordability concerns will require more housing units to be built on already scarce urban land, and will therefore require a densification of present dwelling patterns. However, the low-density single-family home remains the preferred form of housing for many North Americans, and many who live in multi-unit apartments already find them lacking relative to single-detached options. This graduate project aims to achieve a detailed understanding of how specific attributes of available housing options of varying densities affect housing satisfaction, separate from the effects of density itself. This research is then used to inform a design strategy for a new multi-unit housing typology for Vancouver that can be customized by residents and adapt over time to suit changing needs. Such a strategy could improve resident satisfaction with multi-unit housing, and both ease and motivate a transition from single-family homes toward a denser form of urban living in the city’s single-family neighbourhoods.

description: We construct an anomalous dimension for small x evolution which goes beyond standard fixed order perturbative evolution by including resummed small x logarithms deduced from the leading order BFKL equation with running coupling. Surprisingly, we find that once running coupling effects are properly taken into account, the leading approximation is very close to standard perturbative evolution in the range of x accessible at HERA, in overall agreement with the data, with no need for phenomenological parameters to summarise subleading effects. We also show that further corrections due to subleading small x logarithms derived from the Fadin-Lipatov kernel can be kept under control, but that they involve substantial resummation ambiguities which limit their practical usefulness.

description: In the multidisciplinary field of educational research in Germany a diverse range of research data infrastructures and services has developed over the last decade. These differ with regard to topical scope, types of data, range of services, and the scientific communities they address. This manifold but rather fragmented service infrastructure is in some regards dysfunctional from a researcher's perspective. To overcome these barriers to optimal use of existing data infrastructures, the German Network for Educational Research Data (a project funded by the German Ministry of Research) aims at building up a federated infrastructure for research data offering harmonized support services on the basis of common standards and procedures. The network is based upon a collaboration of three established data centers. In its first funding period, the project focused on harmonizing metadata schemes and standardizing curation procedures for offering joint archiving services and on advancing comprehensibility, quality, and visibility of the studies and data within the field. In its current funding period, the project aims to broaden the network of participant data centers in educational science and adjacent disciplines. In our presentation, we will discuss our concept of a federated infrastructure and highlight challenges, opportunities, and risks.

description: The problem of team formation in a social network asks for a set of individuals who not only have the required skills to perform a task but who can also communicate effectively with each other. Existing work assumes that all links in a social network are positive, that is, they indicate friendship or collaboration between individuals. However, it is often the case that the network is signed, that is, it contains both positive and negative links, corresponding to friend and foe relationships. Building on the concept of structural balance, we provide definitions of compatibility between pairs of users in a signed network, and algorithms for computing it. We then define the team formation problem in signed networks, where we ask for a compatible team of individuals that can perform a task with small communication cost. We show that the problem is NP-hard even when there are no communication cost constraints, and we provide heuristic algorithms for solving it. We present experimental results with real data to investigate the properties of the different compatibility definitions, and the effectiveness of our algorithms.

description: Let $M^n$ be a closed, connected $n$-manifold. Let $\mtm$ denote the Thom spectrum of its stable normal bundle. A well known theorem of Atiyah states that $\mtm$ is homotopy equivalent to the Spanier-Whitehead dual of $M$ with a disjoint basepoint, $M_+$. This dual can be viewed as the function spectrum, $F(M, S)$, where $S$ is the sphere spectrum. $F(M, S)$ has the structure of a commutative, symmetric ring spectrum in the sense of \cite{hss}, \cite{ship}. In this paper we prove that $\mtm$ also has a natural, geometrically defined, structure of a commutative, symmetric ring spectrum, in such a way that the classical duality maps of Alexander, Spanier-Whitehead, and Atiyah define an equivalence of symmetric ring spectra, $α: \mtm \to F(M, S)$. We discuss applications of this to Hochshield cohomology representations of the Chas-Sullivan loop product in the homology of the free loop space of $M$.

description: We present Chandra observations of 18 spectroscopically selected quasars, already known to be X-ray weak from previous ROSAT observations. All the sources but one are detected by Chandra, and spectral analysis suggests that most of them are intrinsically underluminous in the X-rays (by a factor from 3 to >100). These objects could represent a large population of quasars with a Spectral Energy Distribution different from that of standard blue quasars. We discuss the possibility that a significant fraction of the obscured AGN needed in Synthesis models of the X-ray background could be instead optically broad-line, X-ray weak quasars.

description: Globular clusters contain multiple stellar populations with peculiar chemical compositions. Pollution of the intracluster gas by an early population of fast-evolving stars is the most common scenario for explaining the observations. Stars with masses in excess of 1000 Msun have recently been suggested as potential polluters. We investigate the spectral properties of proto-GCs that would host a supermassive star. Our main goal is to quantify how such a star would affect the integrated light of the cluster, and to study the detectability of such objects. We computed non-LTE atmosphere models for SMS with various combinations of stellar parameters (luminosity, effective temperature, and mass) and metallicities appropriate for GCs, and we predict their emergent spectra. Using these spectra, we calculated the total emission of young proto-GCs with SMS as predicted in a previously reported scenario, and we computed synthetic photometry in UV, optical, and near-IR bands, in particular for the JWST. At an effective temperature of 10000 K, the spectrum of SMSs shows a Balmer break in emission. This feature is due to strong non-LTE effects (implied by the high luminosity) and is not observed in normal stars. The hydrogen lines also show a peculiar behavior, with Balmer lines in emission while higher series lines are in absorption. At 7000 K, the Balmer break shows a strong absorption. At high effective temperatures, the Lyman break is found in emission. Cool and luminous SMSs are found to dominate the integrated spectrum of the cluster, except for the UV range. The predicted magnitudes of these proto-GCs are m_AB~28-30 between 0.7 and 8 um and for redshifts z~4-10, which is detectable with the JWST. The peculiar observational features of cool SMSs imply that they might in principle be detected in color-color diagrams that probe the spectral energy distribution below and above the Balmer break.

We first describe the calculation of the BPM pickup signals as nonlinear functions of beam position using Green's reciprocity theorem with a two-dimensional formalism. We then describe the incorporation of these calculations in our beam position measurements by inverting the nonlinear functions, giving us beam position as a function of the pickup signals, and how this is also used to improve our measurement of the betatron phase advance. Measurements are presented comparing this system with the linearized pickup response used historically at CESR.

description: We analyse the most general odd-intrinsic-parity effective Lagrangian of QCD valid for processes involving one pseudoscalar with vector mesons described in terms of antisymmetric tensor fields. Substantial information on the odd-intrinsic-parity couplings is obtained by constructing the vector-vector-pseudoscalar Green's three-point function, at leading order in 1/Nc, and demanding that its short-distance behaviour matches the corresponding OPE result. The QCD constraints thus enforced allow us to predict the decay amplitude omega -> pion gamma, and the O(p^6) corrections to pion -> gamma gamma. Noteworthy consequences concerning the vector meson dominance assumption in the decay omega -> 3 pions are also extracted from the previous analysis.

description: Bis(thiomorpholinyldithicarbamate)Cu(II) complex was prepared and characterized by single crystal X-ray crystallography. The molecular structure revealed a mononuclear copper(II) ion bonded to two thiomorpholinyl dithiocarbamate anion to form a distorted square planar geometry. The compound was thermolyzed at 130°C to prepare CuS nanoparticle confirmed as pure hexagonal covellite crystalline phase by powder X-ray diffraction (pXRD). HRTEM image showed CuS nanoparticle with particle sizes in the range 23.3–48.8 nm. The lattice fringes confirm polycrystalline nanoparticles with an interplanar distance of 0.24 nm that corresponds with the lattice plane (101) of hexagonal CuS. SAED patterns confirmed the crystallinity by showing two separate diffraction rings ascribed to (101) and (102) lattice planes of hexagonal CuS phase. The CuS nanoparticles exhibited excellent photocatalytic activity for methylene blue (MB) and methyl orange (MO) dyes degradation.

description: Rationing the use of fixed capacity facilities subject to congestion costs by using fees is complicated in practice by the difficulty of estimating quality-adjusted demand schedules for the facility. Previous approaches to measuring congestion costs have met with limited success. An alternative methodology based on indexation techniques is presented and then applied to a popular urban lake in Arizona. It is concluded that estimating quality-adjusted user fees through the use of indexation techniques has several advantages over earlier approaches.

description: The CESSDA (Consortium of European Social Science Data Archives) Metadata Management project (CMM1) produced in May 2017 the CESSDA Metadata Standards Portfolio Version 1, containing the CESSDA Metadata Core Model and the multilingual CESSDA Controlled Vocabularies. They are based on DDI Lifecycle 3.2 and DDI CVs. Right now, the second phase of the project is on its way. This presentation will provide a rough overview of the extended CESSDA Core Metadata Model, the CVs and accompanying documentation and guidance. We will show how the model supports other CESSDA services like the Product and Service Catalogue and the Euro Question Bank. CMM has its roots in previous metadata work within CESSDA and individual CESSDA Service Providers. The challenge is to look both backwards and into the future. Add to the equation project partners from eight different organisations and countries, the quickly changing metadata world, CESSDA's evolution from a network of European data archives into a legal entity and large-scale infrastructure, and you have an interesting setting with plenty of potential and plenty of potential pitfalls. We will discuss our metadata journey, experiences and lessons learned, and share the moments of joy and despair we've experienced along the way.

description: A key scientific goal of exoplanet surveys is to characterize the underlying population of planets in the local galaxy. In particular, the properties of accreting protoplanets can inform the rates and physical processes of planet formation. We develop a novel method to compute sensitivity to protoplanets in emission-line direct-imaging surveys, enabling estimates of protoplanet population properties under various planetary accretion and formation theories. In this work, we specialize to the case of H-alpha and investigate three formation models governing the planetary-mass-to-mass-accretion-rate power law, and two accretion models that describe the scaling between total accretion luminosity and observable H-alphaline luminosity. We apply our method to the results of the Magellan Giant Accreting Protoplanet Survey (GAPlanetS) to place the first constraints on accreting companion occurrence rates in systems with transitional circumstellar disks. We compute the posterior probability for transitional disk systems to host an accreting companion (-7 < log MMdot <-3) within 2 arcseconds (~200 au). Using our two accretion models, we find consistent protoplanet rates, with median and 68% credible intervals of 0.16 (+0.19, -0.10) and 0.22 (+0.26, -0.14) accreting companions per star, respectively. Our technique enables studying protoplanet populations under flexible assumptions about planet formation. This formalism provides the statistical underpinning necessary for protoplanet surveys to discriminate among formation and accretion theories for planets and brown dwarfs.

Using a 3D two-phase (gas-dust) SPH code, we investigate the combined effects of growth and fragmentation of a multi-phase dust with different fragmentation thresholds in a time-evolving disc. We find that our fiducial disc, initially in a fragmentation regime, moves toward a pure-growth regime in a few thousands years. Timescales change as a function of the disc and dust properties. When fragmentation is efficient, it produces, in different zones of the disc, Fe/Si and rock/ice ratios different from those predicted when only pure growth is considered. Chemical fractionation and the depletion/enrichment in iron observed in some chondrites can be linked to the size-density sorting and fragmentation properties of precursor dusty grains . We suggest that aggregation of chondritic components could have occurred where/when fragmentation was not efficient if their aerodynamical sorting has to be preserved. Chondritic components would allow aerodynamical sorting in a fragmentation regime only if they have similar fragmentation properties. We find that, in the inner disc, and for the same interval of time, fragmenting dust can grow larger when compared to the size of grains predicted by pure growth. This counter-intuitive behaviour is due to the large amount of dust which piles up in a fragmenting zone followed by the rapid growth that occurs when this zone transitions to a pure growth regime. As an important consequence, dust can overcome the radial-drift barrier within a few thousands years.

description: We compute the statistical distribution of index-1 saddles surrounding a given local minimum of the $p$-spin energy landscape, as a function of their distance to the minimum in configuration space and of the energy of the latter. We identify the saddles also in the region of configuration space in which they are subdominant in number (i.e., rare) with respect to local minima, by computing large deviation probabilities of the extremal eigenvalues of their Hessian. As an independent result, we determine the joint large deviation probability of the smallest eigenvalue and eigenvector of a GOE matrix perturbed with both an additive and multiplicative finite-rank perturbation.

Proctacanthella

description: Proctacanthella Bromley
 Proctacanthella Bromley, 1934: 96. Type species: Asilus cacopilagus Hine (orig. des.). Hull, 1962: 498; Martin & Papavero, 1970: 82. Catalogue.
 Remarks. Proctacanthella is a small genus thus far limited to western United States and northern Mexico (E. Fisher, pers. com. 2006). The 5 species in this genus are small to median size [11–25 mm] flies with a gradually inclined face, moderately produced ventrally, and elongated tapered abdomens that extend to or just beyond the wing tips (Fisher, 1997). The anatergite is bare, vein R 5 meets the wing margin below the apex, and the female ovipositor is round in cross-section and bears a circlet of spines. Superficially, members of the genus are a smaller version of Proctacanthus Macquart [see remarks section under this genus] but are distinguished from the latter by its smaller size, wing venation and terminalia. Here we report the genus from the Dominican Republic for the first time.

description: It has been uncovered that compounds containing thiazole moiety display noteworthy biological properties, which have attracted the attention of many researchers in chemical biology as well as in medicinal chemistry. In the current examination, ten 2-(2-hydrazineyl)thiazole derivatives were studied using density functional theory (DFT). The geometry of all ten molecules was optimized by employing the DFT method with the B3LYP/6-311G (d,p) basis set. For the detailed structural and spectroscopic examination, the (E)-4-phenyl-2-(2-(1,2,6,7-tetrahydro-8H-indeno[5,4-b]furan-8-ylidene)hydrazineyl)thiazole (PIFHT) was studied as a representative molecule. The bond lengths and bond angles of the PIFHT molecule were discussed for the detailed understanding of the structural entities. The electronic parameters of all ten molecules were analyzed by computing HOMO and LUMO pictures. Using frontier molecular orbital analysis, spectroscopic and quantum chemical parameters were evaluated and discussed to explore the chemical reactivity of the molecules. Besides, absorption energies, oscillator strength, and electronic transitions of PIFHT molecule were explored using time-dependent density-functional theory (TD-DFT) at the B3LYP/6-311G (d,p) level of theory in the gas phase, dichloromethane, and dimethyl sulfoxide solvents. The TD-DFT computed theoretical UV-Visible spectra of the PIFHT molecule were compared with the experimental UV-Visible spectra. The scaled vibrational frequencies were compared with the experimental frequencies for the assignment of the vibrational bands. The comparisons between computed and experimental UV-Visible and IR spectral results are gratifying. The molecular electrostatic surface potential plots were computed for locating the reactivity sites. Mulliken atomic charges were also studied for acquiring insights into charge density.
Constraining photon-axion oscillations using quasar spectra

Subjects: subject: Astrophysics (astro-ph)

description: Using quasar spectra from the SDSS survey, we constrain the possibility of photon-axion oscillations as a source of dimming of high redshift objects. Such a process has been suggested as an explanation of the apparent faintness of distant Type Ia supernovae. For most combinations of magnetic field strengths and plasma densities along the line of sight, large beam attenuations in broad band filters would also lead to significant differential attenuation, not observed in the quasar sample. However, this conservative study does not exclude the possibility of 0.1 mag dimming of Type Ia supernovae for average plasma densities n_e = 10^(-8) cm^(-3). NIR and MIR spectroscopic studies of high-z sources may be used put further constrains or provide indirect evidence for the existence of a very light axion.

description: Thieno-fused subporphyrazines (TPs) containing a central and axially substituted boron atom are a class of compounds with interesting optical and redox properties. Here we present our efforts towards expanding this class of compounds using various thiophene substrates that were prepared by cyanation or nitration of 3,4-dibromothiophene. Moreover, we show that one TP derivative forms a 2:1 complex in the solid state with C70.

Fully polarized states and decoherence

description: The aim of this review is to show how ``ferromagnetic'' states, that is, states having a fully polarization, can produce intrinsic decoherence by unitary evolution. This effect can give an understanding of recent experiments on mesoscopic devices as quantum point contacts showing the 0.7 conductance anomaly and the wide number of data about saturation of dephasing time observed at very low temperatures, as a fully polarized two dimensional electron gas. But similar effects can be seen in different area of physics as for example the Dicke model describing the interaction of two-level systems with a radiation mode. In this case one can show that decoherence is intrinsic and remove a Schrödinger cat state leaving a single coherent state, collapsing the wave function in the thermodynamic limit. So, saturation of dephasing time at low temperatures in mesoscopic devices can be understood by a fully polarized two dimensional electron gas that, by an exchange model, can be reduced to a generalized form of the Dicke Hamiltonian and where the quasiparticles are spin excitations interacting with magnons. In this way, one can see that several experiments on nanowires and quantum dots can be satisfactorily explained. The existence of intrinsic decoherence in the thermodynamic limit could have deep implications in fundamental problems like quantum measurement and irreversibility. Recent experiments with cavities with a large number of photons and with nuclear magnetic resonance in organic molecular crystals give a first strong support to this view.

description: Let $X$ be a compact Hausdorff space and $A$ a Banach algebra. We investigate amenability properties of the algebra $C(X,A)$ of all $A$-valued continuous functions. We show that $C(X,A)$ has a bounded approximate diagonal if and only if $A$ has a bounded approximate diagonal; if $A$ has a compactly central approximate diagonal (unbounded) then $C(X,A)$ has a compactly approximate diagonal. Weak amenability of $C(X,A)$ for commutative $A$ is also considered.
