description: The excitation ansatz for tensor networks is a powerful tool for simulating the low-lying quasiparticle excitations above ground states of strongly correlated quantum many-body systems. Recently, the two-dimensional tensor network class of infinite entangled pair states gained new ground state optimization methods based on automatic differentiation, which are at the same time highly accurate and simple to implement. Naturally, the question arises whether these new ideas can also be used to optimize the excitation ansatz, which has recently been implemented in two dimensions as well. In this paper, we describe a straightforward way to reimplement the framework for excitations using automatic differentiation, and demonstrate its performance for the Hubbard model at half filling.

Taxonomic investigation of selected species of Staurastrum meyen and Staurodesmus teiling from lakes of the Lower Fraser Valley, British Columbia
Creators: name: Contant, Hélêne
Publisher: name: University of British Columbia
Year: 2010

description: An investigation of selected taxa of Staurastrum and Staurodesmus (Desmidiaceae, Desmidiales, Chlorophyta) was undertaken to help clarify their taxonomy. The study was conducted on samples collected in the lower Fraser Valley (British Columbia). Sampling was done over a 2 1/2 year period in four main lakes (Jacobs, Munday, Lost and Como Lakes) with physico-chemical analyses (pH, temperature, irradiation, alkalinity, dissolved oxygen, calcium, nitrate, phosphate) used to characterize the habitats. Observations of field material revealed nine new records and 56 new distribution records of Staurastrum for British Columbia. One hundred and thirty-six clones comprising 18 taxa of Staurastrum and two taxa of Staurodesmus out of 310 clones of desmids successfully isolated in culture were studied. Morphological variation of the clonal isolates was studied with the light microscope and the scanning electron microscope (SEM). Cell dimensions and cell radiation were measured in each of the 136 clones studied and the length:width ratio (L/l), standard deviation and coefficient of variation were calculated for each. For the 199 taxa studied, more than 350 publications were consulted. These included original descriptions, records of distribution of taxa studied as well as infraspecific and related taxa. Comparison of variations observed in culture and field material were made with the literature and 33 synonyms were proposed. Growth and morphological studies in different environmental conditions (medium, irradiation, temperature, pH) were carried out with a triradiate clone of Staurastrum inflexum Brebisson (clone HC 18). Growth rate varied in the different environmental conditions tested but morphological variation was usually not affected. An analysis of variance showed no significant difference between cell size or cell radiation in different conditions, although higher pH (6.20 compared to 4.62) produced more tetraradiate cells. Attempts to induce sexual reproduction in different environmental conditions were unsuccessful. Control clones of St. gladiosum Turner and Cosmarium botrytis Meyen ex Ralfs from culture collections did show conjugation in similar conditions.

description: We suggest a new spin-4 self-dual model (parity singlet) and a new spin-4 parity doublet in $D=2+1$. They are of higher order in derivatives and are described by a totally symmetric rank-4 tensor without extra auxiliary fields. Despite the higher derivatives they are ghost free. We find gauge invariant field combinations which allow us to show that the canonical structure of the spin-4 (spin-3) models follows the same pattern of its spin-2 (spin-1) counterpart after field redefinitions. For $s=1,2,3,4$, the spin-$s$ self-dual models of order $2s-1$ and the doublet models of order $2s$ can be written in terms of three gauge invariants. The cases $s=3$ and $s=4$ suggest a restricted conformal higher spin symmetry as a principle for defining linearized topologically massive gravity and linearized "New Massive Gravity" for arbitrary integer spins. A key role in our approach is played by the fact that the Cotton tensor in $D=2+1$ has only two independent components for any integer spin.

description: Researchers and designers have incorporated social media affordances into learning technologies to engage young people and support personally relevant learning, but youth may reject these attempts because they do not meet user expectations. Through in-depth case studies, we explore the sociotechnical ecosystems of six teens (ages 15-18) working at a science center that had recently introduced a digital badge system to track and recognize their learning. By analyzing interviews, observations, ecological momentary assessments, and system data, we examined tensions in how badges as connected learning technologies operate in teens' sociotechnical ecosystems. We found that, due to issues of unwanted context collapse and incongruent identity representations, youth only used certain affordances of the system and did so sporadically. Additionally, we noted that some features seemed to prioritize values of adult stakeholders over youth. Using badges as a lens, we reveal critical tensions and offer design recommendations for networked learning technologies.

description: We review the non-anticommutative Q-deformations of N=(1,1) supersymmetric theories in four-dimensional Euclidean harmonic superspace. These deformations preserve chirality and harmonic Grassmann analyticity. The associated field theories arise as a low-energy limit of string theory in specific backgrounds and generalize the Moyal-deformed supersymmetric field theories. A characteristic feature of the Q-deformed theories is the half-breaking of supersymmetry in the chiral sector of the Euclidean superspace. Our main focus is on the chiral singlet Q-deformation, which is distinguished by preserving the SO(4) Spin(4) ``Lorentz'' symmetry and the SU(2) R-symmetry. We present the superfield and component structures of the deformed N=(1,0) supersymmetric gauge theory as well as of hypermultiplets coupled to a gauge superfield: invariant actions, deformed transformation rules, and so on. We discuss quantum aspects of these models and prove their renormalizability in the abelian case. For the charged hypermultiplet in an abelian gauge superfield background we construct the deformed holomorphic effective action.

description: Using path integral techniques, we compute exactly the distribution of the maximal height H_p of p nonintersecting Brownian walkers over a unit time interval in one dimension, both for excursions (p-watermelons with a wall) and bridges (p-watermelons without a wall), for all integer p\ge 1. For large p, we show that < H_p > \sim \sqrt{2p} (excursions) whereas < H_p > \sim \sqrt{p} (bridges). Our exact results prove that previous numerical experiments only measured the pre-asymptotic behaviors and not the correct asymptotic ones. In addition, our method establishes a physical connection between vicious walkers and random matrix theory.

description: In this present article, we study different accretion properties regarding viscous accretion of dark energy. Modified Chaplygin gas is chosen as the dark energy candidate. Viscosity is encountered with the help of Shakura-Sunyaev viscosity parameter. We study sonic speed vs radial distance curves. We compare between adiabatic and dark energy dominated cases and follow that sonic speed falls as we go nearer to the central gravitating object. As viscosity is imposed, a threshold drop in accretion sonic speed is followed. Average rate of fall in accretion sonic speed is increased with black hole's spin. This is signifying that this kind of accretion is weakening the overall matter/energy infall. Specific angular momentum to Keplerian angular momentum ratio is found to fall as we go far from the black hole. Accretion Mach number turns high as we go towards the inner region and high wind Mach number is not allowed as we are going out. Combining, we conclude that the system weakens the feeding process of accretion.

description: In-plane torque measurements were performed on heavy fermion CeCoIn$_5$ single crystals in the temperature $T$ range 1.8 K $\leq T \leq 10$ K and applied magnetic field $H$ up to 14 T. The normal-state torque is given by $τ_n \propto H^4(1+T/T_K)^{-1}\sin 4ϕ$. The reversible part of the mixed-state torque, obtained after subtracting the corresponding normal state torque, shows also a four-fold symmetry. In addition, sharp peaks are present in the irreversible torque at angles of $π/$4, 3$π$/4, 5$π$/4, 7$π$/4, etc. Both the four-fold symmetry in the reversible torque and the sharp peaks in the irreversible torque of the mixed state imply $d_{xy}$ symmetry of the superconducting order parameter. The field and temperature dependences of the reversible mixed-state torque provide further evidence for $d_{xy}$ wave symmetry. The four-fold symmetry in the normal state has a different origin since it has different field and temperature dependences than the one in the mixed state. The possible reasons of the normal state four-fold symmetry are discussed.

description: Sleep posture analysis is widely used for clinical patient monitoring and sleep studies. Earlier research has revealed that sleep posture highly influences symptoms of diseases such as apnea and pressure ulcers. In this study, we propose a robust deep learning model capable of accurately detecting subjects and their sleeping postures using the publicly available data acquired from a commercial pressure mapping system. A combination of loss functions is used to discriminate subjects and their sleeping postures simultaneously. The experimental results show that our proposed method can identify the patients and their in-bed posture with almost no errors in a 10-fold cross-validation scheme. Furthermore, we show that our network achieves an average accuracy of up to 99% when faced with new subjects in a leave-one-subject-out validation procedure on the three most common sleeping posture categories. We demonstrate the effects of the combined cost function over its parameter and show that learning both tasks simultaneously improves performance significantly. Finally, we evaluate our proposed pipeline by testing it over augmented images of our dataset. The proposed algorithm can ultimately be used in clinical and smart home environments as a complementary tool with other available automated patient monitoring systems.

Effects of carbon dioxide enrichment on growth, photosynthesis, and leaf senescence in bean (Phaseolus vulgaris L.) plants
Creators: name: Ehret, David Lloyd
Publisher: name: University of British Columbia
Year: 2010

description: Incremental increases in absolute growth rate with increasing carbon dioxide concentrations ranging from 340 to 3000- ul 1⁻¹ were observed in continuously carbon dioxide enriched bean plants over the course of development. However, relative growth rate of enriched plants was enhanced only early in development. Unit leaf rate was also increased by enrichment primarily in early development, explaining, in part, the trends in relative growth rate. Carbon dioxide enrichment also caused large increases in leaf dry weight, which constituted the major change in carbon partitioning among plant parts. Leaves of enriched plants showed a decrease in photosynthetic capacity which was not associated with changes in chlorophyll concentration, or photorespiration rate. The decrease .in capacity was less evident in older leaves, or in those maintained at low light intensity or with reduced chlorophyll levels, suggesting that the reduced photosynthetic capacity was due to the higher photosynthetic rate of those leaves during growth. Respiration rate in leaves of enriched plants was also increased, but only under conditions which caused a concurrent decrease in photosynthetic capacity. Enriched leaves consistently showed higher starch content with generally a lower photosynthetic capacity that control leaves. Furthermore, an increase in sink demand did not influence the photosynthetic capacity and starch content of enriched leaves to the extent of control leaves. A high leaf starch content and leaf dry weight correlated with accelerated senescence of plants. Conditions such as temperature, which facilitated resulted in the most rapid and the primary leaves of enriched high light intensity or reduced greater starch accumulation, also extensive senescence.

description: The subject of calculating the topological charge (TC) or vortex strength of optical vortices has generated divided opinions among scientists. This is due to the fact that proper analytical results are hard to support from the experimental point of view, leading to different results and conclusions. In this work we will present numerical data that shows the limits of TC measurements for practical fractional vortices and the possible challenges that high order measurements may pose. By analyzing the far field phase and the behavior of the transitions we have shown that they follow specific curves that depend not only on the TC but also on the beam waist. This leads us to present a new "strength staircase" for practical vortices. Our aim is to give some insight in practical scenarios that have not been taken into account in previous results.

description: The paper is devoted to the study of nonlinear stochastic Schrödinger equations driven by standard cylindrical Brownian motions (NSSEs) arising from the unraveling of quantum master equations. Under the Born--Markov approximations, this class of stochastic evolutions equations on Hilbert spaces provides characterizations of both continuous quantum measurement processes and the evolution of quantum systems. First, we deal with the existence and uniqueness of regular solutions to NSSEs. Second, we provide two general criteria for the existence of regular invariant measures for NSSEs. We apply our results to a forced and damped quantum oscillator.

description: The stability of integrators dealing with high order Differential Algebraic Equations (DAEs) is a major issue. The usual procedures give rise to instabilities that are not predicted by the usual linear analysis, rendering the common checks (developed for ODEs) unusable. The appearance of these difficult-toexplain and unexpected problems leads to methods that arise heavy numerical damping for avoiding them. This has the undesired consequences of lack of convergence of the methods, along with a need of smaller stepsizes. In this paper a new approach is presented. The algorithm presented here allows us to avoid the interference of the constraints in the integration, thus allowing the linear criteria to be applied. In order to do so, the integrator is applied to a set of instantaneous minimal coordinates that are obtained through the application of the null space. The new approach can be utilized along with any integration method. Some experiments using the Newmark method have been carried out, which validate the methodology and also show that the method behaves in a predictable way if one considers linear stability criteria.

Intriguingly, our metamaterial structure yields exceptionally strong resonant optical activity, which also leads to the appearance of a backward wave, a characteristic sign of negative-index media.

description: Magneto-ionic control of magnetic properties through ionic migration has shown promise in enabling new functionalities in energy-efficient spintronic devices. In this work, we demonstrate the effect of helium ion irradiation and oxygen implantation on magneto-ionically induced exchange bias effect in Gd/Ni$_{0.33}$Co$_{0.67}$O heterostructures. Irradiation using $He^+$ leads to an expansion of the Ni$_{0.33}$Co$_{0.67}$O lattice due to strain relaxation. At low He+ fluence ($\leq$ 2$\times$10$^{14}$ ions cm$^{-2}$), the redox-induced interfacial magnetic moment initially increases, owing to enhanced oxygen migration. At higher fluence, the exchange bias is suppressed due to reduction of pinned uncompensated interfacial Ni$_{0.33}$Co$_{0.67}$O spins. For oxygen implanted samples, an initial lattice expansion below a dose of 5$\times$10$^{15}$ cm$^{-2}$ is subsequently dominated at higher dose by a lattice contraction and phase segregation into NiO and CoO-rich phases, which in turn alters the exchange bias. These results highlight the possibility of ion irradiation and implantation as an effective means to tailor magneto-ionic effects.

Cloning and characterization of the genes for polynucleotide phosphorylase and ribosomal protein S15 in Escherichia coli
Creators: name: Evans, Sylvia
Publisher: name: University of British Columbia
Year: 2010

description: In order to understand the regulation of polynucleotide phosphorylase (PNPase) in Escherichia coli and elucidate its physiological role, the gene for PNPase (pnp) was cloned and characterized. The orientation of the PNPase gene was determined to be anticlockwise on the E_. coli genetic map by means of mapping Tn5 insertions which resulted in truncated peptides. The PNPase clone also produced a < 12,000 MW protein, now known to be ribosomal protein S15 encoded by rpsO. The DNA sequence covering the major 51 transcription termini and control regions for both genes, the entire coding sequence of S15, and possibly the initial coding sequence of PNPase has been obtained. The DNA sequence of S15 agrees with the published protein sequence (Morinaga et al., 1976) with the exception of an additional histidine codon corresponding to amino acid 45. Transcriptional and translational studies of these genes have been carried out by means of β-galactosidase assays and SI mapping of rpsO-lacZ and pnp-lacZ fusion plasmids. The pnp-lacZ fusions have a high level of β-galactosidase activity. Lack of significant β-galactosidase activity in an rpsO-lacZ fusion suggests that S15, like other core ribosomal proteins, may repress its own translation. This is supported by SI mapping results which indicate that the rpsO promoter is active in the rpsO-lacZ fusion. Sequences of the rpsO DNA show some homology to the region of 16S rRNA which binds S15. Mapping results with nuclease SI indicate that the major transcription initiation site for S15 is approximately 100 bp upstream of its AUG start, while that of pnp is approximately 140 bp upstream of its putative AUG start. The major termination event of rpsO transcription occurs approximately 40 bp after the UAA stop codon for S15. A secondary termination event occurs 93 bp distal to this. Evidence from deletion plasmids (Portier, 1982) and Tn5 insertions which result in the disappearance of PNPase protein suggest that the control regions characterized are indeed those for pnp. However, the possibility that the protein fusion thought to be pnp-lacZ is actually the fusion of a small peptide, immediately preceding pnp, to lacZ cannot be excluded.

Этот период начинается с правления митрополитов из династии Петровичей (Petrović), продолжается до международного признания Черногории в 1878 г. и далее до 1918 г. Наряду с анализом практики ведения делопроизводства в XIX в. особое внимание уделено нормативному регулированию архивной деятельности. Введение правовых норм было результатом расширения знаний в области создания специализированных учреждений, в задачи которых входит сохранение не только документов, имеющих историческое значение, но и являющихся результатом нормативной работы государственных органов, особенно после обретения Черногорией независимости в 1878 г.
В статье рассматривается порядок хранения важных документов в Черногории, который в течение долгого времени не соответствовал архивным стандартам. С развитием первых архивных учреждений возникла необходимость регламентировать их деятельность и порядок работы нормативными актами.

description: Numerous protoplanetary discs show distinct spiral arms features. While possibly caused by a range of processes, detailed pattern analysis points at close stellar flybys as cause for some of them. Surprisingly, these discs reside in young low-mass clusters, where close stellar flybys are expected to be rare. This fact motivated us to take a fresh look at the frequency of close flybys in low-mass clusters. In the solar neighbourhood, low-mass clusters have smaller half-mass radii than their more massive counterparts. We show that this observational fact results in the mean and central stellar density of low-mass clusters being approximately the same as in high-mass clusters, which is rarely reflected in theoretical studies. We perform N-body simulations of the stellar dynamics in young clusters obeying the observed mass-radius relation. Taking the mean disc truncation radius as a proxy for the degree of influence of the environment, we find that the influence of the environment on discs is more or less the same in low- and high-mass clusters. Even the fraction of small discs($

description: Our main result states that whenever we have a non-Euclidean norm $\|\cdot\|$ on a two-dimensional vector space $X$, there exists some $x\neq 0$ such that for every $λ\neq 1, λ>0$, there exist $y, z\in X$ verifying that $\|y\|=λ\|x\|$, $z\neq 0$, and $z$ belongs to the bisectors $B(-x,x)$ and $B(-y,y)$. Throughout this paper we also state and prove some other simple but maybe useful results about the geometry of the unit sphere of strictly convex planes.

description: Keplerian accretion discs around massive black holes (MBHs) are gravitationally unstable beyond a few hundredths of parsec and should collapse to form stars. Indeed an accretion/star formation episode took place a few millions years ago in the Galactic Center (GC). This raises the question of how the disc can survive in AGN and quasars and continue to transport matter towards the black hole. We study the accretion/star formation process, with one aim in mind, to show that a spectrum similar to the observed AGN one can be produced by the disc. We compute models of stationary accretion discs, both continuous and clumpy. Continuous discs must be maintained in a state of marginal stability for the rate of star formation to remain modest, so they require additional heating and transport of angular momentum. Non-viscous heating can be provided by stellar illumination, but momentum transport by supernovae is insufficient to sustain a marginal state, except at the very periphery of the disc. In clumpy discs it is possible to account for the required accretion rate through interactions between clouds, but this model is unsatisfactory as its parameters are tightly constrained without any physical justification. Finally one must appeal to non-stationary discs with intermittent accretion episodes like those that occurred in the GC, but such a model is probably not applicable to luminous high redshift quasars neither to radio-loud quasars.

description: A multiply-accumulate (MAC) operation is the main computation unit for DSP applications. DSP blocks are one of the efficient solutions to implement MACs in FPGA's. However, since the DSP blocks have wide multiplier and adder blocks, MAC operations using low bit-length parameters lead to an underutilization problem. Hence, an efficient approximation technique is introduced. The technique includes manipulation and approximation of the low bit-length fixed-point parameters based upon a Single DSP - Multiple Multiplication (SDMM) execution. The SDMM changes the traditional MAC implementation in the DSP block by separating multiplication and accumulation operations. While the accumulator hardware available in the DSP block is used for multiple parameter multiplication, parallel LUTs are employed for the accumulation part of the MAC operation. The accuracy of the developed optimization technique was evaluated for different CNN weight bit precisions using the Alexnet and VGG-16 networks and the Tiny ImageNet dataset. The optimization can be implemented without loss of accuracy in almost all cases, while it causes slight accuracy losses in a few cases. Through these optimizations, the SDMM is performed at the cost of a small hardware overhead. For example, a single DSP block executes 3 8-bit fixed-point parameter multiplications. As a result of our optimizations, the parameters are represented in a different format on off-chip memory, providing up to 33% compression without any hardware cost. The compression rate can be further increased by up to 97% when used in conjunction with other compression methods for the VGG-16. Reaching this compression rate requires extra hardware cost. A prototype systolic array architecture was implemented employing our optimizations on a Xilinx Zynq FPGA. It reduced the number of DSP blocks by 66.6%, 75%, and 83.3% for 8, 6, and 4-bit input variables, respectively.

description: The cross sections for the pp -> ppK+K- reaction were measured at three beam energies 2.65, 2.70, and 2.83 GeV at the COSY-ANKE facility. The shape of the K+K- spectrum at low invariant masses largely reflects the importance of K\bar{K} final state interactions. It is shown that these data can be understood in terms of an elastic K+K- rescattering plus a contribution coming from the production of a K0\bar{K}0 pair followed by a charge-exchange rescattering. Though the data are not yet sufficient to establish the size of the cusp at the K0\bar{K}0 threshold, the low mass behaviour suggests that isospin-zero production is dominant.

description: We investigated changes in and factors affecting American adolescents' subjective wellbeing during the early months (April - August 2020) of the coronavirus pandemic in the United States. Twenty-one teens (14 - 19 years) participated in interviews at the start and end of the study and completed ecological momentary assessments three times per week between the interviews. There was an aggregate trend toward increased wellbeing, with considerable variation within and across participants. Teens reported greater reliance on networked technologies as their unstructured time increased during lockdown. Using multilevel growth modeling, we found that how much total time teens spent with technology had less bearing on daily fluctuations in wellbeing than the satisfaction and meaning they derived from their technology use. Ultimately, teens felt online communication could not replace face-to-face interactions. We conducted two follow-up participatory design sessions with nine teens to explore these insights in greater depth and reflect on general implications for design to support teens' meaningful technology experiences and wellbeing during disruptive life events.
