Walt Whitman, poet of the body : stylistics of (dis)embodiment
Creators: name: Hubert, Denise Dawn
Publisher: name: University of British Columbia
Year: 2011

description: This thesis proposes a unified theory for reading and interpreting Leaves of Grass (1891-92), by American poet Walt Whitman (1819-1892). This theory proceeds from the premises that spiritual themes are foundational for the poems, and that Whitman's chief poetic aim is to lead readers toward a spiritual understanding of human experience. This theory proposes that the material and spiritual realms coexist and interact continuously, and that human comprehension of an organized, coherent cosmic scheme is possible within the framework of material, temporal life, thanks to the innate divinity of the human being. This project employs linguistic pragmatic theories to examine the subjectivity of Whitman's speaker's consciousness in terms of how it situates and represents itself, and how it relates to the real and conceptual worlds around it. I analyse cohesion (M.A.K. Halliday) and flow of consciousness (Wallace Chafe) in Whitman's poetry to illustrate that he deliberately employs stylistics of disembodiment and de-situation to shift the focus of his poetry away from the material world, toward the spiritual realm. This analysis is broken into themed segments: 1) the speaker and his conception of his self (poems analysed include "Song of Myself and "Starting from Paumanok"); 2) the speaker's interpersonal relationships (poems analysed include "I Sing the Body Electric," "The Sleepers," and "Whoever You Are Holding Me Now in Hand"); and 3) the speaker's interaction with his nation and cosmos (poems analysed include "Crossing Brooklyn Ferry," "When Lilacs Last in the Dooryard Bloom'd," and "A Noiseless Patient Spider"). These poems reveal a speaker with privileged conceptual access to the spiritual realm, which he interprets for readers, hoping this will spark them to develop their own cosmic awareness. The speaker redefines elements of the material world, like the body and its desires, or political life in a democracy, illustrating that these have spiritual significance; they forge connections between souls. Consequently, these spiritual connections valorize mundane pursuits. Moreover, this process of redefinition, or translation, charges his often eroticized discourse with spirituality, rendering it appropriate as public, national discourse for the United States in the latter half of the nineteenth-century.

description: In this paper we develop a framework for multivariate functional approximation by a suitable Gaussian process via an exchangeable pairs coupling that satisfies a suitable approximate linear regression property, thereby building on work by Barbour (1990) and Kasprzak (2020). We demonstrate the applicability of our results by applying it to joint subgraph counts in an Erdős-Renyi random graph model on the one hand and to vectors of weighted, degenerate $U$-processes on the other hand. As a concrete instance of the latter class of examples, we provide a bound for the functional approximation of a vector of success runs of different lengths by a suitable Gaussian process which, even in the situation of just a single run, would be outside the scope of the existing theory.

description: In this paper we study quotients of posets by group actions. In order to define the quotient correctly we enlarge the considered class of categories from posets to loopfree categories: categories without nontrivial automorphisms and inverses. We view group actions as certain functors and define the quotients as colimits of these functors. The advantage of this definition over studying the quotient poset (which in our language is the colimit in the poset category) is that the realization of the quotient loopfree category is more often homeomorphic to the quotient of the realization of the original poset. We give conditions under which the quotient commutes with the nerve functor, as well as conditions which guarantee that the quotient is again a poset.

description: We study the impact and subsequent retraction dynamics of liquid droplets upon high-speed impact on hydrophobic surfaces. Performing extensive experiments, we show that the drop retraction rate is a material constant and does not depend on the impact velocity. We show that when increasing the Ohnesorge number, $\Oh=η/\sqrt{ρR_{\rm I} γ}$, the retraction, i.e. dewetting, dynamics crosses over from a capillaro-inertial regime to a capillaro-viscous regime. We rationalize the experimental observations by a simple but robust semi-quantitative model for the solid-liquid contact line dynamics inspired by the standard theories for thin film dewetting.

Torso-mounted visual servoing of an outdoor robotic manipulator
Creators: name: Ziraknejad, Nima
Publisher: name: University of British Columbia

description: In the majority of vision applications, sensor calibration is a prerequisite to proper use of the sensor for both measurement and control. The objective in camera calibration is to estimate a set of parameters to construct a mapping between the 3D position of a target point and its 2D image coordinates. This thesis presents an autonomous stereo camera calibration technique based on a pinhole camera model with applications in industrial outdoor visual servoing systems. An efficient iterative least-squares parameter estimation algorithm is used to estimate the camera model parameters. The obtained stereo camera model is used to estimate the pose of the target object during the robot servoing process. The heavy-duty stereo camera rig is installed on the torso of an outdoor 3DOF robotic manipulator. The stereo camera calibration is entirely an autonomous process as the robot moves the calibration tool within its workspace and the stereo camera model is produced after the data collection process. The stereo cameras are treated as a single unit and a single transformation is obtained for the stereo camera pair in the system. The calibration process is fast, efficient and no human interaction is required during the process. The developed vision system is capable of detecting the 3D positions of the objects within the robot workspace with an average error of 1.93cm (maximum error of 7.6cm) for a region equal and smaller than the region in which the camera calibration is performed. The errors are comprised of errors in camera calibration, robot positioning and image processing. The maximum error represents an error of 2.1% of the total robot workspace reach. The visual servoing tasks are being performed with an update rate of 29ms. The complete visual servo system, used for pipe handling, has been implemented on a combined platform with two main processing units and a fully integrated 3DOF torso-mounted robotic manipulator. The processing units include an industrial PC104 embedded system with 900MHz Pentium III CPU for vision related tasks and an industrial Programmable Logic Control (PLC) unit for low level control of the robot.

description: Das Kalktuff-Vorkommen im Quellgebiet der Radegast südlich von Gadebusch (Mecklenburg-Vorpommern) gehört aufgrund von Qualität und Ausdehnung sowie der aktuellen Bildung von Kalktuff zu den bedeutendsten Vorkommen im Binnenland von Mecklenburg-Vorpommern. Nach Auswertung vorhandener Unterlagen und Archivdaten wurden mit Hilfe von Sondierungsbohrungen und Laboranalysen Verbreitung, Mächtigkeit und Aufbau des Kalktuffs untersucht. Die hydrogeologischen Voraussetzungen für die Bildung dieses Vorkommens werden beschrieben. Nur im engeren Quellgebiet der Radegast konnte Kalktuff nachgewiesen werden, begünstigt durch den Zustrom von kalkreichem Grundwasser aus einem südlich gelegenen, mächtigen Grundwasserleiter. Das Grundwasser tritt hier im Hangbereich aus, wo der überlagernde Grundwassergeringleiter (Geschiebemergel) auskeilt. Erfasst wurden Wechsellagerungen von Kalktuffen und Quellsedimenten mit höheren Silikat- oder organischen Anteilen. Die Mächtigkeit der Kalktuff-Lagen beträgt in der Regel wenige Dezimeter. Aktuelle Kalktuffbildung findet ausschließlich im Randbereich der Quellbäche statt, eine begünstigende Rolle spielt dabei das Starknervmoos (Palustriella commutata). Die Untersuchungen stützen den vorhandenen Schutzstatus als Biotop und Geotop.
description: This contribution describes a calcareous tufa site in the spring area of the Radegast river south of the town Gadebusch (Mecklenburg-Western Pomerania, Germany). It is one of the most important sites in Mecklenburg-Western Pomerania due to its quality and extent as well as current calcareous tufa formation. After analyzing the available documents and historical data from the archives, the local extension, peat depth and development of calcareous tufa were examined using small diameter drillings and laboratory analyses. The hydrogeological conditions responsible for the development were described. Calcareous tufa was found only in close proximity to the spring area of the Radegast River. The formation is favored by calcium-rich groundwater from a subsurface deep aquifer south of the site. The groundwater seeps from the slope where the overlaying aquitard (till) extends. Alternating strata of calcareous tufa and spring sediments with high proportions of silicate and organic components were observed. The depth of the calcareous tufa was a few decimeters up to 2 - 3 m. Current calcareous tufa formation only occurs in the periphery of the spring brook, where the curled hookmoos (Palustriella commutata) dominates. The study results strongly support the actual protective status as a biotope and geotope.

description: Topological insulators in odd dimensions are characterized by topological numbers. We prove the well-known relation between the topological number given by the Chern character of the Berry curvature and the Chern-Simons level of the low energy effective action for a general class of Hamiltonians bilinear in the fermion with general U(1) gauge interactions including non-minimal couplings by an explicit calculation. A series of Ward-Takahashi identities are crucial to relate the Chern-Simons level to a winding number, which could then be directly reduced to Chern character of Berry curvature by carrying out the integral over the temporal momenta.

title: Functional characterisation of a HOX/PBX transcriptional complex
Creators: name: Di Rocco, Giuliana
Publisher: name: The Open University
Year: 1999

description: Hox genes control cell fates and specify regional identities during vertebrate development. Hox proteins relaxed DNA-binding selectivity in vitro, suggests that Hox specificity of action is achieved in vivo through the action of transcriptional cofactors. Members of the EXD/PBX family of homeoproteins have been proposed for such a role on the basis of genetic and biochemical evidence. In this work we show that the human Pbxl and HOXBl proteins can cooperatively activate transcription through a genetically charaterized Hox responsive element, the autoregulatory enhancer of the mouse Hoxb-1 gene (b-1ARE), which directs the spatially restricted expression of Hoxb-1 in the fourth rhombomere during hindbrain development. On the b-lARE, only a restricted subset of HOX proteins is able to bind cooperatively and activate transcription. Selective recognition of the b-lARE is mediated by the N-terminal region of the HOX homeodomain. The DNA binding and protein-protein interaction functions of HOXBl and Pbxl are all necessary for the assembly of a transcriptionally active complex on the b-lARE. Functional dissection of the complex allowed the localization of the main activation domain in the HOXBl N-terminal region, and of an additional one in the C-terminal region of Pbxl, which is absent in one of its two alternative splicing isoforms. The transcriptional activity of HOX/Pbxl complexes on the b-lARE element is maximal and further restricted in embryonal carcinoma (EC) cells compared to other cell lines. Mutational analysis shows that an octamer-binding protein consensus site on the b-lARE contributes to the activity of the enhancer in transfected cells and it is bound in vitro by octamer-like proteins from both EC cells and embryonic extracts.

description: Cosmic acceleration may be the result of unknown physical processes involving either new fields in high energy physics or modifications of gravitation theory. In the latter case, such modifications are usually related to the existence of extra dimensions (which is also required by unification theories), giving rise to the so-called brane cosmology. In this paper we investigate the phenomenon of the acceleration of the Universe in a particular class of brane scenarios in which a large scale modification of gravity arises due to a gravitational \emph{leakage} into extra dimensions. By using the most recent supernova observations we study the transition (deceleration/acceleration) epoch as well as the constraints imposed on the parameters characterizing the model. We show that these models provide a good description for the current supernova data, which may be indicating that the existence of extra dimensions play an important role not only in fundamental physics but also in cosmology.

Auf die Rolle des Pino mugo-Sphagnetum wird im Zusammenhang mit der Drainage von Mooren hingewiesen und die klimabedingten Unterschiede beider Moore werden diskutiert. Diese manifestieren sich im Wildmoos teilweise in der Etablierung des Vaccinio uliginosi-Pinetum anstelle des Pino mugo-Sphagnetum. Auf das Vorhandensein von Schlenken im Wildmoos und die Rolle von Mineralbodenwasserzeigern in beiden Mooren wird eingegangen.
description: Two moderately degraded raised bogs of the Bavarian Alpine foreland are compared by phytosociology and site ecology: the „Birnbaumer Filz“ at the margins of the Alps and the „Wildmoos“ 59 km northwards in the terminal area of the formerly glaciated alpine foreland. Based on phytosociological relevés typical plant communities, the flora, and selected site conditions (pH and electrical conductivity) are described and analysed. The role of the Pino mugo-Sphagnetum and the continuing drainage of bogs is highlighted. Climatic differences between the two bogs are responsible for the establishment of Vaccinio uliginosi-Pinetum instead of the Pino mugo-Sphagnetum in the Wildmoos. The hummock-hollow pattern in the Wildmoos and the role of minerotrophic indicators are discussed.

description: In order to investigate the charge symmetry breaking (CSB) in the short range part of the nuclear force, we calculate the difference of the masses of the neutron and the proton, $Δ{\rm M}$, the difference of the scattering lengths of the p-p and n-n scatterings, $Δa$, and the difference of the analyzing power of the proton and the neutron in the n-p scattering, $ΔA(θ)$, by a quark model. In the present model the sources of CSB are the mass difference of the up and down quarks and the electromagnetic interaction. We investigate how much each of them contributes to $Δ{\rm M}$, $Δa$ and $ΔA(θ)$. It is found that the contribution of CSB of the short range part in the nuclear force is large enough to explain the observed $ΔA(θ)$, while $Δa$ is rather underestimated.

description: Hydrodynamic phenomena can be observed with light thanks to the analogy between quantum gases and nonlinear optics. In this Letter, we report an experimental study of the superfluid-like properties of light in a (1+1)-dimensional nonlinear optical mesh lattice, where the arrival time of optical pulses plays the role of a synthetic spatial dimension. A spatially narrow defect at rest is used to excite sound waves in the fluid of light and measure the sound speed. The critical velocity for superfluidity is probed by looking at the threshold in the deposited energy by a moving defect, above which the apparent superfluid behaviour breaks down. Our observations establish optical mesh lattices as a promising platform to study fluids of light in novel regimes of interdisciplinary interest, including non-Hermitian and/or topological physics.

description: Inter-operator spectrum sharing in millimeter-wave bands has the potential of substantially increasing the spectrum utilization and providing a larger bandwidth to individual user equipment at the expense of increasing inter-operator interference. Unfortunately, traditional model-based spectrum sharing schemes make idealistic assumptions about inter-operator coordination mechanisms in terms of latency and protocol overhead, while being sensitive to missing channel state information. In this paper, we propose hybrid model-based and data-driven multi-operator spectrum sharing mechanisms, which incorporate model-based beamforming and user association complemented by data-driven model refinements. Our solution has the same computational complexity as a model-based approach but has the major advantage of having substantially less signaling overhead. We discuss how limited channel state information and quantized codebook-based beamforming affect the learning and the spectrum sharing performance. We show that the proposed hybrid sharing scheme significantly improves spectrum utilization under realistic assumptions on inter-operator coordination and channel state information acquisition.

Hydrodynamical simulations of convection-related stellar micro-variability. I. Statistical relations for photometric and photocentric variability

description: Local-box hydrodynamical model atmospheres provide statistical information about the spatial dependence, as well as temporal evolution, of a star's emergent radiation field. Here, we consider late-type stellar atmospheres for which temporal changes of the radiative output are primarily related to convective (granular) surface flows. We derived relations for evaluating the granulation-induced, disk-integrated thus observable fluctuations of the stellar brightness and location of the photocenter from radiation intensities available from a local model. Apart from their application in the context of hydrodynamical stellar atmospheres, these formulae provide some broader insight into the nature of the fluctuations under consideration. Brightness fluctuations scale inversely proportional to the square root of the number of convective cells (the statistically independently radiating surface elements) present on the stellar surface and increase with more pronounced limb-darkening. Fluctuations of the stellar photocentric position do not depend on the number of cells and are largely insensitive to the degree of limb-darkening. They amount to a small fraction of the typical cell size, and can become a limiting factor for high-precision astrometry in the case of extreme giants. The temporal brightness and positional fluctuations are statistically uncorrelated but closely related in magnitude.

title: An investigation into the use of genetic algorithms for shape recognition
Creators: name: Egan, Thomas Michael
Publisher: name: The Open University
Year: 1999

description: The use of the genetic algorithm for shape recognition has been investigated in relation to features along a shape boundary contour. Various methods for encoding chromosomes were investigated, the most successful of which led to the development of a new technique to input normalised 'perceptually important point' features from the contour into a genetic algorithm. Chromosomes evolve with genes defining various ways of 'observing' different parts of the contour. The normalisation process provides the capability for multi-scale spatial frequency filtering and fine/coarse resolution of the contour features. A standard genetic algorithm was chosen for this investigation because its performance can be analysed by applying schema analysis to the genes. A new method for measurement of gene diversity has been developed. It is shown that this diversity measure can be used to direct the genetic algorithm parameters to evolve a number of 'good' chromosomes. In this way a variety of sections along the contour can be observed. A new and effective recognition technique has been developed which makes use of these 'good' chromosomes and the same fitness calculation as used in the genetic algorithm. Correct recognition can be achieved by selecting chromosomes and adjusting two thresholds, the values of which are found not to be critical. Difficulties associated with the calculation of a shape's fitness were analysed and the structure of the genes in the chromosome investigated using schema and epistatic analysis. It was shown that the behaviour of the genetic algorithm is compatible with the schema theorem of J. H. Holland. Reasons are given to explain the minimum value for the mutation probability that is required for the evolution of a number of' good' chromosomes. Suggestions for future research are made and, in particular, it is recommended that the convergence properties of the standard genetic algorithm be investigated.

description: We perform simulations in order to reveal the effect of observational and physical parameters on the reconstruction of a spiral structure in an accretion disk, using eclipse mapping techniques. We show that a model spiral structure is smeared to a ``butterfly''-shape structure because of the azimuthal smoothing effect of the technique. We isolate the effects of phase resolution, signal-to-noise ratio and accurate centering of the eclipse at zero phase. We further explore disk emissivity factors such as dilution of the spiral structure by the disk light and relative spiral arm difference. We conclude that the spiral structure can be satisfactorily recovered in accretion disk eclipse maps with phase resolution |Δϕ| < 0.01, S/N>25 and zero phase uncertainty |Δϕ| < 0.005, assuming the two spiral arms have similar brightness and contribute > 30 % to the total disk light. Under the light of the performed simulations, we present eclipse maps of the IP Peg accretion disk reconstructed from eclipse light curves of emission lines and continuum during the outburst of August 1994, where spiral shocks were detected with the aid of Doppler tomography (Morales-Rueda et al. 2000). We discuss how the detection of spirals shocks with eclipse mapping is improved with the use of velocity-resolved eclipse light curves which do not include any contaminating low-velocity emission.

description: Charge-density waves (CDWs) in Weyl semimetals (WSMs) have been shown to induce an exotic axionic insulating phase in which the sliding mode (phason) of the CDW acts as a dynamical axion field, giving rise to a large positive magneto-conductance [Wang et al., Phys. Rev. B 87, 161107(R) (2013); Roy et al., Phys. Rev. B 92, 125141 (2015); J. Gooth et al., Nature 575, 315 (2019)]. In this work, we predict that dynamical strain can induce a bulk orbital magnetization in time-reversal- (TR-) invariant WSMs that are gapped by a CDW. We term this effect the "dynamical piezomagnetic effect" (DPME). Unlike in [J. Gooth et al., Nature 575, 315 (2019)], the DPME introduced in this work occurs in a bulk-constant (i.e., static and spatially homogeneous in the bulk) CDW, and does not rely on fluctuations, such as a phason. By studying the low-energy effective theory and a minimal tight-binding (TB) model, we find that the DPME originates from an effective valley axion field that couples the electromagnetic gauge field with a strain-induced pseudo-gauge field. In particular, whereas the piezoelectric effects studied in previous works are characterized by 2D Berry curvature, the DPME represents the first example of a fundamentally 3D strain effect originating from the Chern-Simons 3-form. We further find that the DPME has a discontinuous change at a critical value of the phase of the CDW order parameter. We demonstrate that, when there is a jump in the DPME, the surface of the system undergoes a topological quantum phase transition (TQPT), while the bulk remains gapped. Hence, the DPME provides a bulk signature of the boundary TQPT in a TR-invariant Weyl-CDW.

description: We give functorial recipes to get, out of any Hopf algebra over a field, two pairs of Hopf algebras which have some geometrical content. When the ground field has characteristic zero, the first pair is made by a function algebra over a connected Poisson group and a universal enveloping algebra over a Lie bialgebra. In addition, the Poisson group as a variety is an affine space, and the Lie bialgebra as a Lie algebra is graded. Forgetting these last details, the second pair is of the same type. When the Hopf algebra H we start from is already of geometric type the result involves Poisson duality: the first Lie bialgebra associated to H = F[G] is g^* (with g := Lie(G)), and the first Poisson group H = U(g) is of type G^*, i.e. it has g as cotangent Lie bialgebra. If the ground field has positive characteristic, then the same recipes give similar results, but for the fact that the Poisson groups obtained have dimension 0 and height 1, and restricted universal enveloping algebras are obtained. We show how these "geometrical" Hopf algebras are linked to the original one via 1-parameter deformations, and explain how these results follow from quantum group theory. The cases of hyperalgebras and group algebras are examined in some detail (thus recovering some well-known, classical construction), along with some relevant examples.

description: Three-dimensional particle tracking velocimetry (3D-PTV) technique is widely used to acquire the complicated trajectories of particles and flow fields. It is known that the accuracy of 3D-PTV depends on the mapping function to reconstruct three-dimensional particles locations. The mapping function becomes more complicated if the number of cameras is increased and there is a liquid-vapor interface, which crucially affect the total computation time. In this paper, using a shallow neural network model (SNN), we dramatically decrease the computation time with a high accuracy to successfully reconstruct the three-dimensional particle positions, which can be used for real-time particle detection for 3D-PTV. The developed technique is verified by numerical simulations and applied to measure a complex solutal Marangoni flow patterns inside a binary mixture droplet.

description: $Hom(G,H)$ is a polyhedral complex defined for any two undirected graphs $G$ and $H$. This construction was introduced by Lovász to give lower bounds for chromatic numbers of graphs. In this paper we initiate the study of the topological properties of this class of complexes. We prove that $Hom(K_m,K_n)$ is homotopy equivalent to a wedge of $(n-m)$-dimensional spheres, and provide an enumeration formula for the number of the spheres. As a corollary we prove that if for some graph $G$, and integers $m\geq 2$ and $k\geq -1$, we have $\varpi_1^k(\thom(K_m,G))\neq 0$, then $χ(G)\geq k+m$; here $Z_2$-action is induced by the swapping of two vertices in $K_m$, and $\varpi_1$ is the first Stiefel-Whitney class corresponding to this action. Furthermore, we prove that a fold in the first argument of $Hom(G,H)$ induces a homotopy equivalence. It then follows that $Hom(F,K_n)$ is homotopy equivalent to a direct product of $(n-2)$-dimensional spheres, while $Hom(\bar{F},K_n)$ is homotopy equivalent to a wedge of spheres, where $F$ is an arbitrary forest and $\bar{F}$ is its complement.

description: The chemical exploration of extracts from cultures of the marine bacterial isolate PNG-276 yielded the novel antibiotic tauramamide (2.13), a non-ribosomal peptide active against cultures of Enterococcus sp. and methicillin-resistant Staphylococcus aureus (MRSA). A study of extracts of the marine sponge Spirastrella coccinea yielded the novel macrolide methylspirastrellolide C (3.14), which is active against protein phosphatase 2A (PP2A). A third study examined sponge extracts active in a cannabinoid receptor assay, yielding two known compounds, an A- nor -steroid derivative (4.10) and bengamide A (4.11). Neither purified compound was active in the cannabinoid receptor assay, although in both cases this is the first report of these compounds being isolated from Stylissa massa and Hemiasterella aff. affinis sponges, respectively.

title: Investigating Inflammatory Pathways as Therapeutic Targets and Biomarkers using Functional Imaging and Pharmacological Interventions in Epilepsy Models.

description: Epilepsy is a neurological disorder that is characterised by spontaneous seizures. After various epileptogenic injuries, astrocytes become dysfunctional and experimental evidence indicates that these cells contribute to seizure mechanisms. The generation of inflammatory molecules in astrocytes appears to play a key pathogenic role in seizures. However, astrocytes may also contribute to repair the hyperexcitable neuronal networks underlying seizures.

 We focused our studies on understanding the role of astrocytes in epilepsy by (1) developing a new in vivo imaging method to monitor astrocytic cell activation during epileptogenesis and coupled this with their phenotypic characterization; (2) studying the role of Toll-like receptor 3 (TLR3) signaling in seizure mechanisms.

 We report that in vivo bioluminescence imaging is a powerful tool for monitoring astrocytic activation in diseased conditions. Characterization of astrocytic activation during epileptogenesis showed a rapid cell activation corresponding to their inflammatory phenotype while homeostatic (neuroprotective) mechanisms were activated with a delay. Moreover, we demonstrate that in vivo imaging of astrocyte activation allows to study the potential involvement of these cells in the therapeutic effects of anti-inflammatory drugs.

 We also show that priming TLR3 activation in astrocytes with the use of a synthetic agonist results in remarkable anti-inflammatory and anti-ictogenic effects. Mechanistic studies revealed that interferon regulatory factor (IRF)-3/Interferon-β mediated cascade is likely responsible for the inhibitory effects of TLR3 priming on seizures and neuronal excitability. In summary, astroglia activation during the critical epileptogenesis phase provides a potential target for interfering in a timely manner with the inflammatory phenotype of these cells contributing to seizures. Importantly, there are astrocytic cell functions that mediate decreased neuronal excitability and they should be carefully considered when developing treatments targeting these cells for therapeutic purposes.

description: In this paper, our prime objective is to apply the techniques of parameter estimation theory and the concept of Quantum Metrology in the form of Fisher Information to investigate the role of certain physical quantities in the open quantum dynamics of a two entangled qubit system under the Markovian approximation. There exist various physical parameters which characterize such system, but can not be treated as any quantum mechanical observable. It becomes imperative to do a detailed parameter estimation analysis to determine the physically consistent parameter space of such quantities. We apply both Classical Fisher Information (CFI) and Quantum Fisher Information (QFI) to correctly estimate these parameters, which play significant role to describe the out-of-equilibrium and the long range quantum entanglement phenomena of open quantum system. Quantum Metrology, compared to classical parameter estimation theory, plays a two-fold superior role, improving the precision and accuracy of parameter estimation. Additionally, in this paper we present a new avenue in terms of Quantum Metrology, which beats the classical parameter estimation. We also present an interesting result of revival of out-of-equilibrium feature at the late time scales, arising due to the long range quantum entanglement at early time scale and provide a physical interpretation for the same in terms of Bell's Inequality Violation in early time scale giving rise to non-locality.

description: The best marketable tannia cultivars are very susceptible to the tannia rapid yellowing disease, popularly called "burning disease". On-station and on-farm tests using an improved package of cultivation practices were examined in Dominica. The indications were that the yield of tannia carmela increased dramatically from little or no cormels to about 5-10 tonnes per ha at the minimum level. With the improved package of practice farmers are now able to produce tannia under diseased conditions. Emphasis is placed on site selection, drainage, planting material quality, limited use of fungicides, timely application of fertilizer and the early removal of weeds including diseased volunteer tannia host plants.

description: Event extraction (EE) is one of the core information extraction tasks, whose purpose is to automatically identify and extract information about incidents and their actors from texts. This may be beneficial to several domains such as knowledge bases, question answering, information retrieval and summarization tasks, to name a few. The problem of extracting event information from texts is longstanding and usually relies on elaborately designed lexical and syntactic features, which, however, take a large amount of human effort and lack generalization. More recently, deep neural network approaches have been adopted as a means to learn underlying features automatically. However, existing networks do not make full use of syntactic features, which play a fundamental role in capturing very long-range dependencies. Also, most approaches extract each argument of an event separately without considering associations between arguments which ultimately leads to low efficiency, especially in sentences with multiple events. To address the two above-referred problems, we propose a novel joint event extraction framework that aims to extract multiple event triggers and arguments simultaneously by introducing shortest dependency path (SDP) in the dependency graph. We do this by eliminating irrelevant words in the sentence, thus capturing long-range dependencies. Also, an attention-based graph convolutional network is proposed, to carry syntactically related information along the shortest paths between argument candidates that captures and aggregates the latent associations between arguments; a problem that has been overlooked by most of the literature. Our results show a substantial improvement over state-of-the-art methods.
