description: High-order topological charge is of intensive interest in the field of topological matters. In real materials, cubic Dirac point is rare and the chiral charge of one Weyl point (WP) has never be found to exceed |C| = 3 for spin- 1/2 electronic systems. In this work, we argue that a cubic Dirac point can result in one quadruple WP (|C| = 4 with double band degeneracy) when time-reversal symmetry is broken, provided that this cubic Dirac point is away from the high-symmetry points and involves coupling of eight bands, rather than four bands that were thought to be sufficient to describe a Dirac point. The eight-band manifold can be realized in materials with screw symmetry. Near the zone boundary along the screw axis, the folded bands are coupled to their "parent" bands, resulting in doubling dimension of the Hilbert space. Indeed, in "$ε$-TaN (space group 194 with screw symmetry) we find a quadruple WP when applying a Zeeman field along the screw axis. This quadruple WP away from high symmetry points is distinct from highly degenerate nodes at the high-symmetry points already reported. We further find that such a high chiral charge might be related to the parity mixing of bands with high degeneracy, which in turn alters the screw eigenvalues and the resulted chiral charge.

description: Atherosclerosis and rheumatoid arthritis are chronic inflammatory diseases of high incidence worldwide. Both diseases are driven by a complex pathogenesis involving molecular interactions between the myriad of genes or proteins which can be modeled as protein-protein interaction networks (PPIN). Here, we identify the common genes and their functional implications in pathways that underlie the common pathophysiology of RA and atherosclerosis using network analysis of PPIN. By integrating protein-protein interaction (PPI) data and gene-disease associations, we constructed a common PPIN to identify the common genes and their topological significance. We then performed network analysis to identify hub genes based on degree and betweenness centrality. Functional modules were identified and mapped to Gene Ontology (GO) annotations. The resulting PPIN consists of 1379 nodes and 1739 interactions with 26 hub genes representing the union of atherosclerosis and RA related genes. Of these 26 genes, PTGS2, VCAM-1, ICAM-1, TNF-α, ALOX5, TGFβ1 and FOS are identified as both hub and common inflammation genes. Five most significant functional modules are detected and GO analysis reveals that these genes are involved in inflammatory response, regulation of T cell proliferation and response to lipopolysaccharide as biological processes. Three significant pathways validated by KEGG are TNF, NFkB and Interleukin-17 signaling pathways. Dysregulation in both lipid metabolism and T cell differentiation and proliferation were found to be the main triggers causing an inflammatory response which was found to be the common shared pathology that links atherosclerosis and RA. These genes could represent potential biomarkers and drug targets for future research on RA and atherosclerosis and their associated comorbidities.

description: Building on the 1997 work of Chezum and Wimmer, and the 1998 work of Lansford, Freeman, Topliff, and Walker, we estimated a hedonic hammer price model on a random and representative sample of 212 yearlings from the 1999 Keeneland September Yearling Sale. Explanatory variables representing day of sale, age of yearling, stud fee, racing performance of sire and dam, geographic origin of yearling, and yearling health information were statistically significant. In each model, we failed to reject the null hypothesis of no adverse selection; sellers who breed and race horses did not receive a statistically significant price penalty on their yearlings sold in this auction, compared to sellers who just breed horses.

The role of spirituality in the healing process : women survivors of childhood sexual abuse
Creators: name: Bliss, Wynnae Huizinga

description: While childhood sexual abuse is of major societal concern, given the well documented long term psychological effects and trauma on women survivors of childhood sexual abuse, there is a scarcity of empirical data in the literature concerning the role of spirituality in their process of healing. Spirituality is a major component of the human identity. A wholistic understanding of humanity assists in illustrating the importance of spirituality. This exploratory descriptive study researches the role that spirituality has on the healing journey for women survivors of childhood sexual abuse, exploring significant aspects and benefits or hindrances to the healing process.This study has relevance to social work in that it addresses a vast population of individuals Within our society who have been sexually abused. Seven women survivors of childhood sexual abuse were interviewed to explore the role of spirituality in their healing process. The interviews were audiotaped, transcribed, and the data was analyzed using grounded theory. The findings were organized into four categories: Defining Spirituality, Responding to Abuse, Struggling to Heal, and Searching for Meaning. These categories, augmented by their properties and elements were assembled into a conceptual framework. The conceptual findings revealed that religion was a complex and mixed blessing for these women: sometimes it was a complicated hindrance, or it became a beneficial contributor to the healing process. Spirituality on the other hand, became very important in their healing journey of growth, transformation and restoration. It allowed them to identify a sense of meaning in the midst of their pain and struggle, while providing resources and hope, strength and purpose. Through listening to women's stories about the place of spirituality in their lives, effective therapeutic interventions and knowledge pertaining to healing from childhood sexual abuse can be enhanced. Implications arising out of the data include understanding how religion and spirituality may be different, acknowledging the importance of spirituality for survivors and comprehending the nature of anger and forgiveness in the healing process. Further implications include discerning perceptions of the image and gender of God, establishing proper protocol for religious institutions in dealing with the ramifications of childhood sexual abuse, and increasing awareness of the healing power of spirituality for women survivors of childhood sexual abuse.

description: The cotton basis is examined graphically and statistically to determine if the basis differs across U.S. production regions and within the crop year as economic theory predicts. The analysis indicates the basis differs for some, but not all, regions consistent with the theory. Results also show that the typical seasonal pattern is not apparent for regions which export most of their cotton, most likely because demand in these regions is seasonal.

description: The effect of dynamical short-range correlations on the generalized momentum distribution $n(\vec{p},\vec{Q})$ in the case of $Z=N$, $\ell$-closed shell nuclei is investigated by introducing Jastrow-type correlations in the harmonic-oscillator model. First, a low order approximation is considered and applied to the nucleus $^4$He. Compact analytical expressions are derived and numerical results are presented and the effect of center-of-mass corrections is estimated. Next, an approximation is proposed for $n(\vec{p}, \vec{Q})$ of heavier nuclei, that uses the above correlated $n(\vec{p},\vec{Q})$ of $^4$He. Results are presented for the nucleus $^{16}$O. It is found that the effect of short-range correlations is significant for rather large values of the momenta $p$ and/or $Q$ and should be included, along with center of mass corrections for light nuclei, in a reliable evaluation of $n(\vec{p},\vec{Q})$ in the whole domain of $p$ and $Q$.

description: Fast growing scientific topics have famously been key harbingers of the new frontiers of science, yet, large-scale analyses of their genesis and impact are rare. We investigate one possible factor connected with a topic's extraordinary growth: scientific prizes. Our longitudinal analysis of nearly all recognized prizes worldwide and over 11,000 scientific topics from 19 disciplines indicates that topics associated with a scientific prize experience extraordinary growth in productivity, impact, and new entrants. Relative to matched non-prizewinning topics, prizewinning topics produce 40% more papers and 33% more citations, retain 55% more scientists, and gain 37% and 47% more new entrants and star scientists, respectively, in the first five-to-ten years after the prize. Funding do not account for a prizewinning topic's growth. Rather, growth is positively related to the degree to which the prize is discipline-specific, conferred for recent research, or has prize money. These findings reveal new dynamics behind scientific innovation and investment.

description: This analysis examines effects of several common assumptions on net present values (NPVs) of beef cows. While effects on NPVs vary over a price cycle or successive price cycles, several generalities manifest themselves. A cow is not likely to recover the lost revenue from not having just one calf. Incorporating genetic improvement into the herd increases the probability of an older cow being culled. Variable net replacement/culling rates make sense in the context of cattle inventory and price cycles because of the effects cyclical series of prices have on NPV.

These data offer the only comprehensive means of assessing regulatory barriers without relying on expert opinion, although they fall short of placing a dollar value on the volume of trade affected. The data show that meeting food regulations is a significant barrier to Asian food products entering the United States, especially for products originating in developing and newly industrialized countries.

description: Textual adversarial attacking has received wide and increasing attention in recent years. Various attack models have been proposed, which are enormously distinct and implemented with different programming frameworks and settings. These facts hinder quick utilization and fair comparison of attack models. In this paper, we present an open-source textual adversarial attack toolkit named OpenAttack to solve these issues. Compared with existing other textual adversarial attack toolkits, OpenAttack has its unique strengths in support for all attack types, multilinguality, and parallel processing. Currently, OpenAttack includes 15 typical attack models that cover all attack types. Its highly inclusive modular design not only supports quick utilization of existing attack models, but also enables great flexibility and extensibility. OpenAttack has broad uses including comparing and evaluating attack models, measuring robustness of a model, assisting in developing new attack models, and adversarial training.

description: Massive stars condition the evolution of the interstellar medium by the amount of energy released during their lives and especially by their deaths as supernova explosions. The vast amounts of spectroscopic data for massive stars provided by previous and existing instruments on ground-based and space-based telescopes have already saturated our capability to process them by the use of human routines. As a consequence, there is a pressing need for machine-assisted tools to help handle incoming data. To this end, we present the development of a massive star spectroscopic multiwavelength interactive database designed for scientific research and a fully automatic stellar parameter determination tool. Here we show the preliminary results of the application of these tools to optical spectra of O-type stars.

description: New images of M31 at 24, 70, and 160 micron taken with the Multiband Imaging Photometer for Spitzer (MIPS) reveal the morphology of the dust in this galaxy. This morphology is well represented by a composite of two logarithmic spiral arms and a circular ring (radius ~10 kpc) of star formation offset from the nucleus. The two spiral arms appear to start at the ends of a bar in the nuclear region and extend beyond the star forming ring. As has been found in previous work, the spiral arms are not continuous but composed of spiral segments. The star forming ring is very circular except for a region near M32 where it splits. The lack of well defined spiral arms and the prominence of the nearly circular ring suggests that M31 has been distorted by interactions with its satellite galaxies. Using new dynamical simulations of M31 interacting with M32 and NGC 205 we find that, qualitatively, such interactions can produce an offset, split ring like that seen in the MIPS images.

Chaos edges of $z$-logistic maps: Connection between the relaxation and sensitivity entropic indices

description: Chaos thresholds of the $z$-logistic maps $x_{t+1}=1-a|x_t|^z$ $(z>1; t=0,1,2,...)$ are numerically analysed at accumulation points of cycles 2, 3 and 5. We verify that the nonextensive $q$-generalization of a Pesin-like identity is preserved through averaging over the entire phase space. More precisely, we computationally verify $\lim_{t \to\infty}< S_{q_{sen}^{av}} >(t)/t= \lim_{t \to\infty}< \ln_{q_{sen}^{av}} ξ>(t)/t \equiv λ_{q_{sen}^{av}}^{av}$, where the entropy $S_{q} \equiv (1- \sum_i p_i^q)/ (q-1)$ ($S_1=-\sum_ip_i \ln p_i$), the sensitivity to the initial conditions $ξ\equiv \lim_{Δx(0) \to 0} Δx(t)/Δx(0)$, and $\ln_q x \equiv (x^{1-q}-1)/ (1-q) $ ($\ln_1 x=\ln x$). The entropic index $q_{sen}^{av}<1$, and the coefficient $λ_{q_{sen}^{av}}^{av}>0$ depend on both $z$ and the cycle. We also study the relaxation that occurs if we start with an ensemble of initial conditions homogeneously occupying the entire phase space. The associated Lebesgue measure asymptotically decreases as $1/t^{1/(q_{rel}-1)}$ ($q_{rel}>1$). These results led to (i) the first illustration of the connection (conjectured by one of us) between sensitivity and relaxation entropic indices, namely $q_{rel}-1 \simeq A (1-q_{sen}^{av})^α$, where the positive numbers $(A,α)$ depend on the cycle; (ii) an unexpected and new scaling, namely $q_{sen}^{av}(cycle n)=2.5 q_{sen}^{av}(cycle 2)+ ε$ ($ε=-0.03$ for $n=3$, and $ε= 0.03$ for $n=5$).

description: We develop a correction to the density matrix used in density matrix renormalization group calculations to take into account the incompleteness of the environment block. The correction allows successful calculations using only a single site in the center of the system, rather than the standard two sites, improving typical computation times by a factor of two to four. In addition, in many cases where ordinary DMRG can get stuck in metastable configurations, the correction eliminates the sticking. We test the new method on the Heisenberg S=1 chain.

description: Quantum Channel Discrimination (QCD) presents a fundamental task in quantum information theory, with critical applications in quantum reading, illumination, data-readout and more. The extension to multiple quantum channel discrimination has seen a recent focus to characterise potential quantum advantage associated with quantum enhanced discriminatory protocols. In this paper, we study thermal imaging as an environment localisation task, in which thermal images are modelled as ensembles of Gaussian phase insensitive channels with identical transmissivity, and pixels possess properties according to background (cold) or target (warm) thermal channels. Via the teleportation stretching of adaptive quantum protocols, we derive ultimate limits on the precision of pattern classification of abstract, binary thermal image spaces, and show that quantum enhanced strategies may be used to provide significant quantum advantage over known optimal classical strategies. The environmental conditions and necessary resources for which advantage may be obtained are studied and discussed. We then numerically investigate the use of quantum enhanced statistical classifiers, in which quantum sensors are used in conjunction with machine learning image classification methods. Proving definitive advantage in the low loss regime, this work motivates the use of quantum enhanced sources for short-range thermal imaging and detection techniques for future quantum technologies.

In the dual supergravity description, the Higgs branch is described by SU(2) instanton configurations on D7-branes in an AdS background. We compute the spectral flow parameterized by the size of a single instanton. In the large N_c limit, there is a sense in which the flow from zero to infinite instanton size, or Higgs VEV, can be viewed as a closed loop. We show that this flow leads to a non-trivial rearrangement of the spectrum.

description: Resonant motions of integrable systems subject to perturbations may continue to exist and to cover surfaces with parametric equations admitting a formal power expansion in the strength of the perturbation. Such series may be, sometimes, summed via suitable sum rules defining $C^\infty$ functions of the perturbation strength: here we find sufficient conditions for the Borel summability of their sums in the case of two-dimensional rotation vectors with Diophantine exponent $τ=1$ (e. g. with ratio of the two independent frequencies equal to the golden mean).

description: The normal state of optimally doped cuprates is dominated by the "strange metal" phase that shows a linear temperature ($T$) dependence of the resistivity persisting down to the lowest $T$. For underdoped cuprates this behavior is lost below the pseudogap temperature $T^*$, where Charge Density Waves (CDW) together with other intertwined local orders characterize the ground state. Here we show that the $T$-linear resistivity of highly strained, ultrathin and underdoped YBa$_2$Cu$_3$O$_{7-δ}$ films is restored when the CDW amplitude, detected by Resonant Inelastic X-ray scattering, is suppressed. This observation points towards an intimate connection between the onset of CDW and the departure from $T$-linear resistivity in underdoped cuprates. Our results illustrate the potential of using strain control to manipulate the ground state of quantum materials.

Summer resource limitation and over-winter movement and survival of stream-resident coastal cutthroat trout
Creators: name: Boss, Shelly Marrie
Publisher: name: University of British Columbia

description: To what extent are salmonids limited by food and cover in streams? To answer this question, I conducted a summer field experiment to test the effects of food and cover on growth, survival and emigration of coastal cutthroat trout (Oncorhynchus clarki clarki). Resources that affect summer growth can further influence individuals if body size is linked to other aspects of fish ecology, such as over-winter survival. Thus, I also examined whether size at the end of the experiment improved survival over winter. Using a 2x2 factorial design, I manipulated food and cover in stream enclosures containing individually marked trout replicated in two streams. To address how summer growth affects over-winter survival, I monitored the released experimental fish throughout autumn and winter. During summer, fish receiving food additions experienced growth rates 80 times higher than those of unfed fish, indicating marked food limitation. The absence of cover additions increased mortality by approximately 50% in one stream, but had no effect in the other. Emigration was not strongly affected by either factor. Over-winter survival was not explained by body size. Fed fish were still larger than unfed fish by the next spring. Using capture-recapture methods, I further investigated relations between body size and movement, survival and growth during winter for the general population in each stream. Movement during winter was not related to body mass or condition. Survival increased over the size range of the smallest fish, and then gradually decreased as mass increased for larger individuals. On average, growth was positive during winter and relative growth was not related to mass during the coldest part of winter (November to January). This pattern of growth suggests the size-based mortality may not have been due to energetic stress. My results show that during summer, food can limit trout growth, and cover, by mediating predation, can limit survival. How summer growth, or body size in general, affects winter ecology may depend on environmental factors. Size-related movement may be uncommon in winter if temperatures minimize aggression and food demand. Strong positive relationships between body size and winter survival might not be expected when warm temperatures preclude winter starvation, if predator abundance is low, and when low discharge minimizes mortality related to flooding or habitat limitation.

description: This paper presents a novel factor graph-based approach to solve the discrete-time finite-horizon Linear Quadratic Regulator problem subject to auxiliary linear equality constraints within and across time steps. We represent such optimal control problems using constrained factor graphs and optimize the factor graphs to obtain the optimal trajectory and the feedback control policies using the variable elimination algorithm with a modified Gram-Schmidt process. We prove that our approach has the same order of computational complexity as the state-of-the-art dynamic programming approach. Furthermore, current dynamic programming approaches can only handle equality constraints between variables at the same time step, but ours can handle equality constraints among any combination of variables at any time step while maintaining linear complexity with respect to trajectory length. Our approach can be used to efficiently generate trajectories and feedback control policies to achieve periodic motion or repetitive manipulation.

description: A recently developed analytical method for systematic improvement of the convergence of path integrals is used to derive a generalization of Euler's summation formula for path integrals. The first $p$ terms in this formula improve convergence of path integrals to the continuum limit from 1/N to $1/N^p$, where $N$ is the coarseness of the discretization. Monte Carlo simulations performed on several different models show that the analytically derived speedup holds.

description: Much has been written about the challenges facing CARICOM as a result of the liberalization, globalization and integration phenomena. This paper adds value to the conversation by addressing the nexus between and among economic asymmetries, trade liberalization and economic integration, as it relates to CARICOM as small developing economies. The paper seeks to highlight the salient issues of CARICOM economic adjustment challenges under trade liberalization and integration imperatives, particularly as they may be subjected to the constraints of economic asymmetries. In doing so, it steps away from the conventional approach of reciting a series of data usually associated with the issues and instead, engages in commentary and assessment regarding the changing economic landscape in the Region and elsewhere. The issues are indeed very complex and the arguments and conclusions flowing from this type of evaluation may not be in lock-step with the conventional wisdom. However, it is our contention that the regional trade and development policy solutions does not lie in denial of the existence of the problems; but rather, in tackling them head-on and incorporating them into existing and proposed systems of economic relations.

description: We determine all inhomogeneous Yang-Mills algebras and super Yang-Mills algebras which are Koszul. Following a recent proposal, a non-homogeneous algebra is said to be Koszul if the homogeneous part is Koszul and if the PBW property holds. In this paper, the homogeneous parts are the Yang-Mills algebra and the super Yang-Mills algebra.

Connection among stochastic Hamilton-Jacobi-Bellman equation, path-integral, and Koopman operator on nonlinear stochastic optimal control

description: The path-integral control, which stems from the stochastic Hamilton-Jacobi-Bellman equation, is one of the methods to control stochastic nonlinear systems. This paper gives a new insight into nonlinear stochastic optimal control problems from the perspective of Koopman operators. When a finite-dimensional dynamical system is nonlinear, the corresponding Koopman operator is linear. Although the Koopman operator is infinite-dimensional, adequate approximation makes it tractable and useful in some discussions and applications. Employing the Koopman operator perspective, it is clarified that only a specific type of observable is enough to be focused on in the control problem. This fact becomes easier to understand via path-integral control. Furthermore, the focus on the specific observable leads to a natural power-series expansion; coupled ordinary differential equations for discrete-state space systems are derived. A demonstration for nonlinear stochastic optimal control shows that the derived equations work well.

A Sum Rule for Thermal Conductivity and Dynamical Thermal Transport Coefficients in Condensed Matter -I

description: We display an interesting sum rule for the dynamical thermal conductivity for many standard models of condensed matter in terms of the expectation of a thermal operator. We present the thermal operator for several model systems of current interest, which enable an evaluation of the sum rule and the Lorentz number, the thermo electric figure of merit as well as the thermopower at high frequencies. As a by product, we present exact formulae for the T=0 chemical potential $μ(0)$ for charged many-body systems, including the Hubbard model, in terms of expectation values of extensive operators. Simple estimates are provided for the thermopower of an infinitely correlated band model on the triangular lattice, modeling the physics of the sodium cobalt oxide system. The present result goes beyond the Heikes Mott formula for the thermopower, and contains an additional transport correction that is sensitive to the lattice topology as well as the sign of hopping.

description: We present a pedagogical overview of recent theoretical work on unconventional quantum phases and quantum phase transitions in condensed matter systems. Strong correlations between electrons can lead to a breakdown of two traditional paradigms of solid state physics: Landau's theories of Fermi liquids and phase transitions. We discuss two resulting "exotic" states of matter: topological and critical spin liquids. These two quantum phases do not display any long-range order even at zero temperature. In each case, we show how a gauge theory description is useful to describe the new concepts of topological order, fractionalization and deconfinement of excitations which can be present in such spin liquids. We make brief connections, when possible, to experiments in which the corresponding physics can be probed. Finally, we review recent work on deconfined quantum critical points. The tone of these lecture notes is expository: focus is on gaining a physical picture and understanding, with technical details kept to a minimum.

description: Let $F\in\mathbb{C}[x,y]$ be a polynomial, $γ(z)\in π_1(F^{-1}(z))$ a non-trivial cycle in a generic fiber of $F$ and let $ω$ be a polynomial $1$-form, thus defining a polynomial deformation $dF+εω=0$ of the integrable foliation given by $F$.
 We study different invariants: the orbit depth $k$, the nilpotence class}$n$, the derivative length}$d$ associated with the couple $(F,γ)$. These invariants bound the length $\ell$ of the first nonzero Melnikov function of the deformation $dF+εω$ along $γ$.
 We study in detail a simple example of a polynomial $F$ given as product of four lines. We show how these invariants vary depending on the relative position of the four lines and relate it also to the length of the corresponding Godbillon-Vey sequence. We formulate a conjecture motivated by the study of this example.
