description: We introduce a composition of quantum states of a bipartite system which is based on the reshuffling of density matrices. This non-Abelian product is associative and stems from the composition of quantum maps acting on a simple quantum system. It induces a semi-group in the subset of states with maximally mixed partial traces. Subadditivity of the von Neumann entropy with respect to this product is proved. It is equivalent to subadditivity of the entropy of bistochastic maps with respect to their composition, where the entropy of a map is the entropy of the corresponding state under the Jamiolkowski isomorphism. Strong dynamical subadditivity of a concatenation of three bistochastic maps is established. Analogous bounds for the entropy of a composition are derived for general stochastic maps. In the classical case they lead to new bounds for the entropy of a product of two stochastic matrices.

description: We consider massive higher-spin multiplets coupled to quantum gravity and compute their contributions to the gravitational beta functions at one loop. Such theories, if quantized with the Feynman prescription, would contain ghosts. Instead, those degrees of freedom are turned into purely virtual particles by means of the fakeon prescription and the resulting theories are both renormalizable and unitary. We extract the necessary number of fields to obtain asymptotic freedom by solving the relevant renormalization-group equations in the ultraviolet limit. We show that in the case of irreducible rank-$s$ bosons with minimal kinetic term only a certain number of fields with $0\leq s \leq 3$ is compatible with asymptotic freedom. No solution involving fermionic rank-$s$ fields are found. We also consider the cases of rank-$1$ and symmetric rank-$2$ tensor fields with nonminimal kinetic terms and repeat the analysis, finding that the allowed number of fields is enlarged. Possible implications for metric affine theories of gravity are pointed out.

description: The use of uncontrolled financial spreadsheets can expose organizations to unacceptable business and compliance risks, including errors in the financial reporting process, spreadsheet misuse and fraud, or even significant operational errors. These risks have been well documented and thoroughly researched. With the advent of regulatory mandates such as SOX 404 and FDICIA in the U.S., and MiFID, Basel II and Combined Code in the UK and Europe, leading tax and audit firms are now recommending that organizations automate their internal controls over critical spreadsheets and other end-user computing applications, including Microsoft Access databases. At a minimum, auditors mandate version control, change control and access control for operational spreadsheets, with more advanced controls for critical financial spreadsheets. This paper summarises the key issues regarding the establishment and maintenance of control of Business Critical spreadsheets.

Nitrogen and phosphorus retranslocation from needles of douglas-fir growing on three site-types
Creators: name: Parkinson, Joy Anne
Publisher: name: University of British Columbia
Year: 2010

description: Nitrogen and phosphorus retranslocation from needles of Douglas-fir growing on xeric, mesic and hygric sites of the drier subzone of the Coastal Western Hemlock Zone (Krajina, 1969) was estimated by comparing the content in current needles and in needle litter. Linear relationships between nutrient content in current needles and the amount retranslocated (absolute loss) were found to be site-specific and analysis of covariance was used to correct absolute loss for between-site differences in the content of current needles. The absolute loss of nitrogen was significantly higher (p=.05 for all tests) on the mesic sites than on the hygric or xeric sites. Phosphorus retranslocation was significantly different between the three site-types with the hygric having the highest and the xeric the lowest absolute loss. The differences may be explained by the balance between availability and demand for nitrogen and phosphorus on the respective sites. Several other possible reasons for the low retranslocation rates on xeric sites are discussed. No significant difference in needle nitrogen concentration was found between sites. Phosphorus content was lower in needles on the hygric sites than on the xeric or mesic, but for P concentration, an interaction between crown level, hygrotope and needle age prevented statistical analysis. For both elements, the interaction between crown level and needle age indicated that changes in nutrient content and concentration with needle age differed between crown levels. The literature contains a number of variations on the techniques used to evaluate internal cycling and, therefore, careful definition of terms is suggested when comparing between studies.

description: Graph representation learning is crucial for many real-world applications (e.g. social relation analysis). A fundamental problem for graph representation learning is how to effectively learn representations without human labeling, which is usually costly and time-consuming. Graph contrastive learning (GCL) addresses this problem by pulling the positive node pairs (or similar nodes) closer while pushing the negative node pairs (or dissimilar nodes) apart in the representation space. Despite the success of the existing GCL methods, they primarily sample node pairs based on the node-level proximity yet the community structures have rarely been taken into consideration. As a result, two nodes from the same community might be sampled as a negative pair. We argue that the community information should be considered to identify node pairs in the same communities, where the nodes insides are semantically similar. To address this issue, we propose a novel Graph Communal Contrastive Learning (gCooL) framework to jointly learn the community partition and learn node representations in an end-to-end fashion. Specifically, the proposed gCooL consists of two components: a Dense Community Aggregation (DeCA) algorithm for community detection and a Reweighted Self-supervised Cross-contrastive (ReSC) training scheme to utilize the community information. Additionally, the real-world graphs are complex and often consist of multiple views. In this paper, we demonstrate that the proposed gCooL can also be naturally adapted to multiplex graphs. Finally, we comprehensively evaluate the proposed gCooL on a variety of real-world graphs. The experimental results show that the gCooL outperforms the state-of-the-art methods.

description: By using a point canonical transformation starting from the constant-mass Schrödinger equation for the isotonic potential, it is shown that a semiconfined harmonic oscillator model with a position-dependent mass in the BenDaniel-Duke setting and the same spectrum as the standard harmonic oscillator can be easily constructed and extended to a semiconfined shifted harmonic oscillator, which could result from the presence of a uniform gravitational field. A further generalization is proposed by considering a $m$-dependent position-dependent mass for $0

The identification of a third recombinant DNA plasmid encoding a Cellulomonas fimi cellulase gene in Escherichia coli
Creators: name: Wakarchuk, Warren William
Publisher: name: University of British Columbia
Year: 2010

description: A shotgun cloning of Cellulomonas fimi DNA into Escherichia coli yielded 2 types of recombinant plasmids encoding carboxymethylcellulase (CMCase) activity (23). These clones were designated pEC1 and pEC2. A third type of recombinant plasmid containing a different C. fimi cellulase gene has now been isolated and designated pEC3. The new clone was differentiated from E. coli (pEC1) and E. coli (pEC2) by the following characteristics: the size of the C. fimi DNA insert; its restriction digestion pattern and map; the levels of CMCase in cell free extracts; halo formation on CMC-Congo Red plates; and the migration of CMCase activity in non-denaturing polyacrylamide gels. As with E. coli (pEC1) and E. coli (pEC2), CMCase activity was detected in the periplasmic space of E. coli (pEC3).

description: We report Pauli spin blockade in an impurity defined carbon nanotube double quantum dot. We observe a pronounced current suppression for negative source-drain bias voltages which is investigated for both symmetric and asymmetric coupling of the quantum dots to the leads. The measured differential conductance agrees well with a theoretical model of a double quantum dot system in the spin-blockade regime which allows us to estimate the occupation probabilities of the relevant singlet and triplet states. This work shows that effective spin-to-charge conversion in nanotube quantum dots is feasible and opens the possibility of single-spin readout in a material that is not limited by hyperfine interaction with nuclear spins.

description: We report about La0.67Sr0.33MnO3 single crystal manganite thin films in interaction with a gold capping layer. With respect to uncoated manganite layers of the same thickness, Au-capped 4 nm-thick manganite films reveal a dramatic reduction (about 185 K) of the Curie temperature TC and a lower saturation low-temperature magnetization M0. A sizeable TC reduction (about 60 K) is observed even when an inert SrTiO3 layer is inserted between the gold film and the 4 nm-thick manganite layer, suggesting that this effect might have an electrostatic origin.

description: Heterogeneous information network (HIN) embedding aims to find the representations of nodes that preserve the proximity between entities of different nature. A family of approaches that are wildly adopted applies random walk to generate a sequence of heterogeneous context, from which the embedding is learned. However, due to the multipartite graph structure of HIN, hub nodes tend to be over-represented in the sampled sequence, giving rise to imbalanced samples of the network. Here we propose a new embedding method CoarSAS2hvec. The self-avoid short sequence sampling with the HIN coarsening procedure (CoarSAS) is utilized to better collect the rich information in HIN. An optimized loss function is used to improve the performance of the HIN structure embedding. CoarSAS2hvec outperforms nine other methods in two different tasks on four real-world data sets. The ablation study confirms that the samples collected by CoarSAS contain richer information of the network compared with those by other methods, which is characterized by a higher information entropy. Hence, the traditional loss function applied to samples by CoarSAS can also yield improved results. Our work addresses a limitation of the random-walk-based HIN embedding that has not been emphasized before, which can shed light on a range of problems in HIN analyses.

description: Using an l = 1 blazed fork-hologram at the focal plane of the Asiago 122 cm telescope, we obtained optical vortices from the stellar system Rasalgethi (alpha Herculis) and from the single star Arcturus (alpha Bootis). We have analyzed the structure of the optical vortices obtained from non-monochromatic starlight under very poor seeing conditions using a fast CCD camera to obtain speckle patterns and carry out the lucky imaging technique, alternative to adaptive optics. With the insertion of a red filter and of a Lyot stop we performed l = 1 optical vortex coronography the double star HD74010. The results are in agreement with theory and numerical simulations. Our results open the way to applications of optical vortices to ground based astronomical observations, in particular for coronagraphy with l > 1 masks. No intrinsic orbital angular momentum was detected in the starlight.

description: Star-forming galaxies are the sources likely to have reionized the universe. As we cannot observe them directly due to the opacity of the intergalactic medium at $z\gtrsim5$, we study $z\sim3\text{--}5$ galaxies as proxies to place observational constraints on cosmic reionization. Using new deep \textit{Hubble Space Telescope} rest-frame UV F336W and F435W imaging (30-orbit, $\sim40$~arcmin$^2$, $\sim29\text{--}30$~mag depth at 5$σ$), we attempt to identify a sample of Lyman continuum galaxies (LCGs). These are individual sources that emit ionizing flux below the Lyman break ($<912~\textÅ$). This population would allow us to constrain cosmic reionization parameters such as the number density and escape fraction ($f_{\rm esc}$) of ionizing sources. We compile a comprehensive parent sample that does not rely on the Lyman-break technique for redshifts. We present three new spectroscopic candidates at $z\sim3.7\text{--}4.4$, and 32 new photometric candidates. The high-resolution multi-band HST imaging and new Keck/Low Resolution Imaging Spectrometer (LRIS) redshifts make these promising spectroscopic LCG candidates. Using both a traditional and probabilistic approach, we find the most likely $f_{\rm esc}$ values for the three spectroscopic LCG candidates are $>100\%$, and therefore not physical. We are unable to confirm the true nature of these sources with the best available imaging and direct blue Keck/LRIS spectroscopy. More spectra, especially from the new class of 30 m telescopes, will be required to build a statistical sample of LCGs to place firm observational constraints on cosmic reionization.

description: We explore the possibility of modeling electroweak physics in a warped extra dimension with a soft wall. The infrared boundary is replaced with a smoothly varying dilaton field that provides a dynamical spacetime cutoff. We analyze gravity, gauge fields, and fermions in the soft-wall background and obtain a discrete spectrum of Kaluza-Klein states which can exhibit linear Regge-like behavior. Bulk Yukawa interactions give rise to nonconstant fermion mass terms, leading to fermion localization in the soft-wall background and a possible explanation of the Standard Model flavor structure. Furthermore we construct electroweak models with custodial symmetry, where the gauge symmetry is broken with a bulk Higgs condensate. The electroweak constraints are not as stringent as in hard-wall models, allowing Kaluza-Klein masses of order the TeV scale.

Satellite based estimates of solar energy availability at the earth’s surface : impact of changes in the configuration of the satellite data
Creators: name: Wanless, Neil
Publisher: name: University of British Columbia
Year: 2010

description: Despite the encouraging results of recent satellite based estimates of solar energy at the Earth's surface numerous questions concerned with the configuration of the satellite data used in the models remain unanswered. The merits of a wide range of satellite data configurations were assessed using a single relationship between ground-based estimates of shortwave radiation transmission (T) and satellite measured reflectance (TR). Bidirectional reflectance (BDR) models were developed in an attempt to correct the satellite data for the anisotropic reflectance properties of the Earth-Atmosphere system. Irrespective of the type of BDR model used, such a correction for anisotropic reflectance was deemed to be unwarranted. Changes to the spatial configuration of the satellite pixel array and increased concentration of ground based measurements are also found to be of negligible importance. Therefore, as modelling procedures using satellite information characteristically involve voluminous data sets the ability to use small pixel array sizes presents a considerable advantage. Increasing the temporal averaging period resulted in substantial improvements to the strength of the relationship between T and TR. The use of at least two images and at least four images per one-hourly and two-hourly time periods, respectively, have been shown to satisfactorily characterize the observed radiative regimes. Finally, variations in the climatological characteristics for the Lower Fraser Valley study area, highlighted using such a technique, have been eluded to.

Recent discoveries about hadrons with heavy flavours fall into those categories. It is of course the third category that is the most tantalising, but lessons from the first two may help resolve the third.

Notes: —The protologue of C. bravoa (Matuda 1955a: 61–62) provided the following information on type specimens: “ Puebla: Ajemjibre, en bosque alto húmedo, sombreado, noviembre 15 de 1954, Dra. Helia Bravo H. sin número. Tipo en el Herbario Nacional del Instituto de Biología de la Universidad Nacional Autónoma de México ”, “ Veracruz: Orizaba, en Sierra de la Cruz, en el año de 1853, Muller, sin número” and “El último ejemplar citado arriba se encuentra en el Herbario de New York Botanical Garden, registrado como Commelina hirtella Vahl ”. Nevertheless, the holotype could not be located at MEXU. The paratype at NY (NY-03946618— Figure 1) seems to be the only extant original element for C. bravoa. This specimen is in agreement with the morphological description provided in the protologue, and I designate it as lectotype.
It is interesting to note that there is one specimen kept at MEXU identified as C. bravoa (MEXU-7757) that was collected by the same person (Helia Bravo Hollis) at the same locality (“Bosque Ajenjibre”) as the missing holotype, but on a different date (June 1953). No collector number was provided for this specimen. Nevertheless, this specimen cannot be considered original material for C. bravoa, because of the different collection date.
Based on comparison of the morphology of type specimens, I am convinced that the most similar species to C. bravoa is C. pallida (see below). The available records indicate that C. bravoa is endemic to Mexico. Further study is necessary to ascertain the circumscription of C. bravoa and clarify the distribution (and consequently the conservation status) of this species.
Specimens studied: — MEXICO. Puebla state: Bosque Ajenjibre, June 1953, H. Bravo H. s.n. (MEXU-7757); Veracruz state: Orizaba, Sierra de la Cruz, 1853, F. Müller s.n. (NY-03946618).

description: Changs in individual behavior often entangles with the dynamic interaction of individuals, which complicates the epidemic process and brings great challenges for the understanding and control of the epidemic. In this work, we consider three kinds of typical behavioral changes in epidemic process that is, self-quarantine of infected individuals, self-protection of susceptible individuals, and social distancing between them. We connect the behavioral changes with individual's social attributes by the activity-driven network with attractiveness. A mean-field theory is established to derive an analytical estimate of epidemic threshold for SIS models with individual behavioral changes, which depends on the correlations between activity, attractiveness and the number of generative links in the susceptible and infected states. We find that individual behaviors play different roles in suppressing the epidemic. Although all the behavioral changes could delay the epidemic by increasing the epidemic threshold, self-quarantine and social distancing of infected individuals could effectively decrease the epidemic size. In addition, simultaneous changes in these behaviors and the timing of implement of them also play a key role in suppressing the epidemic. These results provide helpful significance for understanding the interaction of individual behaviors in the epidemic process.

description: A class of partial differential equations (a conservation law and four balance laws), with four independent variables and involving sixteen arbitrary continuously differentiable functions, is considered in the framework of equivalence transformations. These are point transformations of differential equations involving arbitrary elements and live in an augmented space of independent, dependent and additional variables representing values taken by the arbitrary elements. Projecting the admitted symmetries into the space of independent and dependent variables, we determine some finite transformations mapping the system of balance laws to an equivalent one with the same differential structure but involving different arbitrary elements; in particular, the target system we want to recover is an autonomous system of conservation laws. An application to a physical problem is considered.

description: This paper presents a reduced-order approach for four-dimensional variational data assimilation, based on a prior EO F analysis of a model trajectory. This method implies two main advantages: a natural model-based definition of a mul tivariate background error covariance matrix $\textbf{B}_r$, and an important decrease of the computational burden o f the method, due to the drastic reduction of the dimension of the control space. % An illustration of the feasibility and the effectiveness of this method is given in the academic framework of twin experiments for a model of the equatorial Pacific ocean. It is shown that the multivariate aspect of $\textbf{B}_r$ brings additional information which substantially improves the identification procedure. Moreover the computational cost can be decreased by one order of magnitude with regard to the full-space 4D-Var method.

Efficient Implementation of BLAS Level-3 solvers for Sylvester-type Matrix Equations

description: The solution of dense Sylvester equations has been considered a solved

problem after the seminal paper by Bartels and Stewart. Variants of their

algorithm have increased the efficiency by rearranging the operations,

especially for the generalized equations. None of the direct approaches goes

beyond a BLAS level-2 formulation, except of the Generalized Schur

method of Kåström and Poromaa from 1994. On the other hand, the RECSY

family of methods works on top of a recursive subdivision into smaller

problems. RECSY can thus accelerate the solution process on many

processors. Still, it has a rather irregular memory access pattern, especially

when the subdivision is not equally sized.

In our contribution, we present a BLAS level-3 type tiling

approach for the solution of (generalized) Sylvester equations, including

the (generalized) Lyapunov and Stein equations, after the reduction of

the coefficients to Schur form. The methods thus accelerate the triangular

solution phase, compared to the BLAS level-2 methods, by the use of different

efficiency improving implementation techniques. On the one hand, the proposed

BLAS level-3 solvers act as an outer iteration that exploits the existing

solvers for solving the arising block problems on the single tiles. On the other

hand, we optimize the existing BLAS level-2 solvers with respect to the

capabilities of modern computer architectures. Beside

this classical BLAS level-3/level-2 type tiling approaches, we combine the newly

evolved methods with features from the latest OpenMP 4/4.5 standard to get

parallel implementation which works independent of the parallel features

provided by the BLAS library.

When the RECSY solver is used as the inner method, the outer iteration

contributes a largely regularized memory access pattern. Therefore also here we

get a notable acceleration with respect to the standalone solver.

For a single equation the runtime is, however, dominated by the reduction of the

coefficient matrices to Hessenberg/Schur form. Therefore, the overall

performance gain is limited. However, the gain can be increased, e.g, when

the equations with the same coefficient needs to be solve for several right

hand sides. This is for example the case if autonomous differential

matrix equations are solved or the condition number of the operator should be

estimated.
Dust Emission from the Perseus Molecular Cloud

description: Using far-infrared emission maps taken by IRAS and Spitzer and a near-infrared extinction map derived from 2MASS data, we have made dust temperature and column density maps of the Perseus molecular cloud. We show that the emission from transiently heated very small grains and the big grain dust emissivity vary as a function of extinction and dust temperature, with higher dust emissivities for colder grains. This variable emissivity can not be explained by temperature gradients along the line of sight or by noise in the emission maps, but is consistent with grain growth in the higher density and lower temperature regions. By accounting for the variations in the dust emissivity and VSG emission, we are able to map the temperature and column density of a nearby molecular cloud with better accuracy than has previously been possible.

description: The WWR-M reactor of PNPI offers a unique opportunity to prepare a source for ultracold neutrons (UCN) in an environment of high neutron flux (about 3*10^12 n/cm^2/s) at still acceptable radiation heat release (about 4*10^-3 W/g). It can be realized within the reactor thermal column situated close to the reactor core. With its large diameter of 1 m, this channel allows to install a 15 cm thick bismuth shielding, a graphite premoderator (300 dm^3 at 20 K), and a superfluid helium converter (35 dm^3). At a temperature of 1.2 K it is possible to remove the heat release power of about 20 W. Using the 4pi flux of cold neutrons within the reactor column can bring more than a factor 100 of cold neutron flux incident on the superfluid helium with respect to the present cold neutron beam conditions at the ILL reactor. The storage lifetime for UCN in superfluid He at 1.2 K is about 30 s, which is sufficient when feeding experiments requiring a similar filling time. The calculated density of UCN with energy between 50 neV and 250 neV in an experimental volume of 40 liters is about 10^4 n/cm^3. Technical solutions for realization of the project are discussed.

description: The term ‘preferred’ is used in conversation analytic research on preference to describe how people systematically time/position and design their social actions in interaction when there are relevant alternatives possible. ‘Preferred’ has been used to refer to: (i) an action that structurally aligns and cooperates with a prior conversational turn’s initiated course of action/project/activity; and (ii) the design of an action—both sequence-initiating (FPP), and sequence-responding (SPP)—that is straightforward and fluent, and delivered at the earliest moment when it may be initially relevantly performed.

description: Recent work by Forsgård indicates that not every convex lattice polygon arises as the characteristic polygon of an affine dimer or, equivalently, an admissible oriented line arrangement on the torus in general position. We begin the classification of convex lattice polygons arising as characteristic polygons of affine dimers. We present several general constructions of new affine dimers from old, and an algorithm for finding affine dimers with prescribed polygon. With these tools we prove that all lattice triangles, generalised parallelograms, and polygons of genus at most two admit an affine dimer.

description: Fluctuation and dissipation dynamics is examined at all temperature ranges for the general case of a background time evolving scalar field coupled to heavy intermediate quantum fields which in turn are coupled to light quantum fields. The evolution of the background field induces particle production from the light fields through the action of the intermediate catalyzing heavy fields. Such field configurations are generically present in most particle physics models, including Grand Unified and Supersymmetry theories, with application of this mechanism possible in inflation, heavy ion collision and phase transition dynamics. The effective evolution equation for the background field is obtained and a fluctuation-dissipation theorem is derived for this system. The effective evolution in general is nonlocal in time. Appropriate conditions are found for when these time nonlocal effects can be approximated by local terms. Here careful distinction is made between a local expansion and the special case of a derivative expansion to all orders, which requires analytic behavior of the evolution equation in Fourier space.

description: We investigate charge distribution in the recently discovered high-$T_c$ superconductors, layered nickelates. With increasing value of charge-transfer energy we observe the expected crossover from the cuprate to the local triplet regime upon hole doping. We find that the $d-p$ Coulomb interaction $U_{dp}$ plays a role and makes Zhang-Rice singlets less favorable, while the amplitude of local triplets is enhanced. By investigating the effective two-band model with orbitals of $x^2-y^2$ and $s$ symmetries we show that antiferromagnetic interactions dominate for electron doping. The screened interactions for the $s$ band suggest the importance of rare-earth atoms in superconducting nickelates.
