description: Fractional derivatives and integrations of non-integers orders was introduced more than three centuries ago but only recently gained more attention due to its application on nonlocal phenomenas. In this context, several formulations of fractional electromagnetic fields was proposed, but all these theories suffer from the absence of an effective fractional vector calculus, and in general are non-causal or spatially asymmetric. In order to deal with these difficulties, we propose a spatially symmetric and causal gauge invariant fractional electromagnetic field from a Lagrangian formulation. From our fractional Maxwell's fields arose a definition for the fractional gradient, divergent and curl operators.

description: Nitrogen regulates multiple aspects of the permafrost climate feedback, including plant growth, organic matter decomposition, and the production of the potent greenhouse gas nitrous oxide. Despite its importance, current estimates of permafrost nitrogen are highly uncertain. Here, we compiled a dataset of >2000 samples to quantify nitrogen stocks in the Yedoma domain, a region with organic-rich permafrost that contains ~25% of all permafrost carbon. We estimate that the Yedoma domain contains 41.2 gigatons of nitrogen down to ~20 metre for the deepest unit, which increases the previous estimate for the entire permafrost zone by ~46%. Approximately 90% of this nitrogen (37 gigatons) is stored in permafrost and therefore currently immobile and frozen. Here, we show that of this amount, ¾ is stored >3 metre depth, but if partially mobilised by thaw, this large nitrogen pool could have continental-scale consequences for soil and aquatic biogeochemistry and global-scale consequences for the permafrost feedback.
Plant community response to post-wildfire management activities in interior Douglas-fir forests of southern BC
Creators: name: Black, Scott T.
Publisher: name: University of British Columbia
Year: 2009

description: Post-wildfire disturbances such as salvage logging and seeding of agronomic species occur over large parts of the forested land base in British Columbia. However, there is surprisingly little research on the effects of these management practices on plant community composition and species diversity. The future of plant and animal biodiversity will depend increasingly on regional floras surviving in highly managed and disturbed environments. I examined vascular and nonvascular plant community responses four years after wildfire and post-wildfire management practices in interior Douglas-fir (Pseudotsuga menziesii var. glauca) forests following two separate 2003 wildfires near Kamloops, BC, Canada. Wildfire sites with all combinations of seeding and salvage logging disturbance were selected in similar post-wildfire environments. Analysis at the plot (400m², n=104) and stand (400-1200m², n=42) scales suggested that post-wildfire disturbance had a significant negative effect on native species richness and reduced the frequency of some shrub and shade tolerance species including Ceanothus sanguineus and Prosartes hookeri. As well, multivariate analysis showed evidence for altered post-wildfire community composition and structure mainly due to increased dominance of exotic and graminoid species. These negative effects were most apparent in wildfire sites that were both seeded and salvaged-logged. Sustainable forest management requires a thorough understanding of the cumulative impacts of post-wildfire management practices on understory vegetation and ecosystem processes. The results of this study can aid resource managers by helping them incorporate the effects of natural and anthropogenic disturbance into future post-wildfire management activities.

description: The proper design of near-infrared light-Absorbing agents enables efficient optoacoustic imaging-guided phototherapy. In particular, several croconaine-based organic agents with excellent optical properties have been recently reported for this purpose. However, most of them absorb light below 800 nm, limiting deep-Tissue imaging applications. To this end, we utilized a recently described novel croconaine derivative (CR880) to develop CR880-based nanoparticles (CR880-NPs) for effective in vivo delivery, deep tissue optoacoustic imaging and photothermal therapy applications. Radicals and strong π-πstacking in CR880 result in an 880 nm absorption peak with no blue-shift upon condensing to the solid phase. DSPE-PEG2000-formulated CR880-NPs exhibited high optoacoustic generation efficiency and photostability, and could be visualized in the tumors of three different mouse tumor models (breast, brain, and colon tumor) with high image contrast. The high photothermal conversion efficiency of CR880-NPs (∼58%) subsequently enabled efficient in vivo tumor elimination using a low energy laser, while remaining biocompatible and well-Tolerated. This work introduces a promising novel agent for cancer theranostics of challenging deep-seated tumors.
Changes in turbulent dissipation in a channel flow with oscillating walls

description: Harmonic oscillations of the walls of a turbulent plane channel flow are studied by direct numerical simulations to improve our understanding of the physical mechanism for skin-friction drag reduction. The simulations are carried out at constant pressure gradient in order to define an unambiguous inner scaling: in this case, drag reduction manifests itself as an increase of mass flow rate. Energy and enstrophy balances, carried out to emphasize the role of the oscillating spanwise shear layer, show that the viscous dissipations of the mean flow and of the turbulent fluctuations increase with the mass flow rate, and the relative importance of the latter decreases. We then focus on the turbulent enstrophy: through an analysis of the temporal evolution from the beginning of the wall motion, the dominant, oscillation-related term in the turbulent enstrophy is shown to cause the turbulent dissipation to be enhanced in absolute terms, before the slow drift towards the new quasi-equilibrium condition. This mechanism is found to be responsible for the increase in mass flow rate. We finally show that the time-average volume integral of the dominant term relates linearly to the drag reduction.

Size-dependent electronic-transport mechanism and sign reversal of magnetoresistance in Nd0.5Sr0.5CoO3

description: A detailed investigation of electronic-transport properties of Nd0.5Sr0.5CoO3 has been carried out as a function of grain size ranging from micrometer order down to an average size of 28 nm. Interestingly, we observe a size induced metal-insulator transition in the lowest grain size sample while the bulk-like sample is metallic in the whole measured temperature regime. An analysis of the temperature dependent resistivity in the metallic regime reveals that the electron-electron interaction is the dominating mechanism while other processes like electron-magnon and electron-phonon scatterings are also likely to be present. The fascinating observation of enhanced low temperature upturn and minimum in resistivity on reduction of grain size is found due to electron-electron interaction (quantum interference effect). This effect is attributed to enhanced disorder on reduction of grain size. Interestingly, we observed a cross over from positive to negative magnetoresistance in the low temperature regime as the grain size is reduced. This observed sign reversal is attributed to enhanced phase separation on decreasing the grain size of the cobaltite.

description: Using molecular dynamics simulations we study the temperature-density phase diagram of a simple model system of particles in two dimensions. In addition to translational degrees of freedom, each particle has two internal states and interacts with a modified Lennard-Jones potential which depends on relative positions as well as the internal states. We find that, despite its simplicity, the model has a rich phase diagram showing many features of common network-forming liquids such as water and silica, including polymorphism and thermodynamic anomalies. We believe our model may be useful for studies concerning generic features of such complex liquids.

Decoherence in photosynthetic energy transfer : based on a spin bath model
Creators: name: Zhu, Zhen
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis we study the coherent energy transfer in photosynthetic systems. This resonant energy transfer has proven to be a coherent transfer in some light harvest complexes. The model which we suggest to describe this mechanism is an exciton hopping on an N-site ring coupled to a spin bath. Analytic results are found for both the dynamics of the influence functional and of the reduced density matrix of the excitons.We also give results for the dynamics of the current as a function of time. By setting states splitting initially into 2 separate wave-packets moving at different velocities, we reproduce the coherent beating phenomenon in experiments.

Year: 2020

description: Riassunto: Il seguente articolo espone una sintetica schedatura delle principali testimonianze protostoriche all’interno del territorio di Monastir. L’obiettivo è stato quello di riesaminare l’evoluzione del paesaggio monastirese per quel che concerne le fasi dell’Età del Bronzo e prima età del Ferro, offrendo una nuova chiave di lettura su alcuni contesti già editi e descritti in passato. L’indagine prende in considerazione e approfondisce gli aspetti legati alla cronologia, rapporti e dinamiche evolutive dei vari agglomerati siti alle pendici e nella sommità del Monte Zara. L’attenzione si è focalizzata nello specifico sul caso di Bia de Monti per il ruolo avuto dal manufatto litico configurato a torre nuragica nel contesto della capanna n. 46 e sulla definizione sacrale assunta dall’insediamento di Is Obias nei secoli iniziali del I millennio a.C. Parole chiave: Monastir, Monte Zara, età Nuragica, età del Bronzo, età del Ferro. Abstract: The article aims to create a unitary work on the past archaeological literature concerning the phases between the Middle Bronze Age to the Early Iron Age, offering as new interpretation of some of the described contexts. The survey takes into consideration and deepens the aspects related to the chronology, relationships and evolutionary dynamics of the various agglomerations located on the slopes and at the top of Mount Zara. Attention was focused specifically on the case of Bia de Monti for the role played by the lithic artefact shaped as a nuragic tower in the context of hut no. 46 and on the sacral definition of the settlement of Is Obias in the early centuries of the first millennium BC. Keywords: Monastir, Monte Zara, Nuragic Age, Bronze Age, Iron Age.

description: Fractal dimension is central to understanding dynamical processes occurring on networks; however, the relation between fractal dimension and random walks on fractal scale-free networks has been rarely addressed, despite the fact that such networks are ubiquitous in real-life world. In this paper, we study the trapping problem on two families of networks. The first is deterministic, often called $(x,y)$-flowers; the other is random, which is a combination of $(1,3)$-flower and $(2,4)$-flower and thus called hybrid networks. The two network families display rich behavior as observed in various real systems, as well as some unique topological properties not shared by other networks. We derive analytically the average trapping time for random walks on both the $(x,y)$-flowers and the hybrid networks with an immobile trap positioned at an initial node, i.e., a hub node with the highest degree in the networks. Based on these analytical formulae, we show how the average trapping time scales with the network size. Comparing the obtained results, we further uncover that fractal dimension plays a decisive role in the behavior of average trapping time on fractal scale-free networks, i.e., the average trapping time decreases with an increasing fractal dimension.

description: A library series of analogues of the natural product fumagillin suitable for photoaffinity labelling were prepared by Rodrigo Pierre and subjected to photoaffinity labelling studies by Dr Tulloch and myself against Trypanosoma brucei. These identified Methionine aminopeptidase 2 and another, as yet unknown molecular target. Investigations were undertaken to validate if this target was 3-methylglutaconyl coenzyme A hydratase (3-MGCoA-H) as suggested by immobilised drug affinity chromatography. These investigations involved the generation of an overexpression cell line and the recombinant expression and purification of the protein. A series of N⁴-benzyl, N²-Phenyl quinazoline diamines were designed and synthesised to uncover structure activity relationships to inform the design of photoaffinity labelling probes. These compounds were found to be potent and selective in Leishmania major. A photoaffinity labelling probe and controls were designed and synthesised from the original SAR. Owing to a significant loss of potency against L. major, initial photoaffinity labelling studies were undertaken in Trypanosoma brucei, revealing several potential target proteins. A library of triphenylphosphonium and tributylphosphonium salts were assessed for their activity against Trypanosoma brucei, Trypanosoma cruzi and Leishmania major. A significant quantity of these compounds were found be potent or very potent against T. brucei and selective with respect to HeLa. The compounds were subjected to synergy studies and phenotypic screening of the KN morphologies and mitochondrial staining.

description: We estimate the strength of interaction-enhanced coherence between two graphene or topological insulator surface-state layers by solving imaginary-axis gap equations in the random phase approximation. Using a self-consistent treatment of dynamic screening of Coulomb interactions in the gapped phase, we show that the excitonic gap can reach values on the order of the Fermi energy at strong interactions. The gap is discontinuous as a function of interlayer separation and effective fine structure constant, revealing a first order phase transition between effectively incoherent and interlayer coherent phases. To achieve the regime of strong coherence the interlayer separation must be smaller than the Fermi wavelength, and the extrinsic screening of the medium embedding the Dirac layers must be negligible. In the case of a graphene double-layer we comment on the supportive role of the remote $π$-bands neglected in the two-band Dirac model.

description: Recently, Hwang et al. [Eur. Phys. J. D. 61, 785 (2011)] and Yuan et al. [Int. J. Theo. Phys. 50, 2403 (2011)] have proposed two efficient protocols of secure quantum communication using 3-qubit and 4-qubit symmetric W state respectively. These two dense coding based protocols are generalized and their efficiencies are considerably improved. Simple bounds on the qubit efficiency of deterministic secure quantum communication (DSQC) and quantum secure direct communication (QSDC) protocols are obtained and it is shown that dense coding is not essential for designing of maximally efficient DSQC and QSDC protocols. This fact is used to design maximally efficient protocols of DSQC and QSDC using 3-qubit and 4-qubit W states.

description: We use polarized inelastic neutron scattering to study low-energy spin excitations and their spatial anisotropy in electron-overdoped superconducting BaFe$_{1.85}$Ni$_{0.15}$As$_{2}$ ($T_c=14$ K). In the normal state, the imaginary part of the dynamic susceptibility, $χ^{\prime\prime}(Q,ω)$, at the antiferromagnetic (AF) wave vector $Q=(0.5,0.5,1)$ increases linearly with energy for $E\le 13$ meV. Upon entering the superconducting state, a spin gap opens below $E\approx 3$ meV and a broad neutron spin resonance appears at $E\approx 7$ meV. Our careful neutron polarization analysis reveals that $χ^{\prime\prime}(Q,ω)$ is isotropic for the in-plane and out-of-plane components in both the normal and superconducting states. A comparison of these results with those of undoped BaFe$_2$As$_2$ and optimally electron-doped BaFe$_{1.9}$Ni$_{0.1}$As$_{2}$ ($T_c=20$ K) suggests that the spin anisotropy observed in BaFe$_{1.9}$Ni$_{0.1}$As$_{2}$ is likely due to its proximity to the undoped BaFe$_2$As$_2$. Therefore, the neutron spin resonance is isotropic in the overdoped regime, consistent with a singlet to triplet excitation.

description: The impact of inhibitory and excitatory synapses in delay-coupled Hodgkin--Huxley neurons that are driven by noise is studied. If both synaptic types are used for coupling, appropriately tuned delays in the inhibition feedback induce multiple firing coherence resonances at sufficiently strong coupling strengths, thus giving rise to tongues of coherency in the corresponding delay-strength parameter plane. If only inhibitory synapses are used, however, appropriately tuned delays also give rise to multiresonant responses, yet the successive delays warranting an optimal coherence of excitations obey different relations with regards to the inherent time scales of neuronal dynamics. This leads to denser coherence resonance patterns in the delay-strength parameter plane. The robustness of these findings to the introduction of delay in the excitatory feedback, to noise, and to the number of coupled neurons is determined. Mechanisms underlying our observations are revealed, and it is suggested that the regularity of spiking across neuronal networks can be optimized in an unexpectedly rich variety of ways, depending on the type of coupling and the duration of delays.

description: We propose an extensive report on the simulation of electronic transport in 2D graphene in presence of structural defects. Amongst the large variety of such defects in sp$^2$ carbon-based materials, we focus on the Stone-Wales defect and on two divacancy-type reconstructed defects. First, based on ab initio calculations, a tight-binding model is derived to describe the electronic structure of these defects. Then, semiclassical transport properties including the elastic mean free paths, mobilities and conductivities are computed using an order-N real-space Kubo-Greenwood method. A plateau of minimum conductivity ($σ^{min}_{sc}= 4e^2/πh$) is progressively observed as the density of defects increases. This saturation of the decay of conductivity to $σ^{min}_{sc}$ is associated with defect-dependent resonant energies. Finally, localization phenomena are captured beyond the semiclassical regime. An Anderson transition is predicted with localization lengths of the order of tens of nanometers for defect densities around 1%.

Proprioception, together with other sensory feedback systems (i.e., vestibular and visual), contribute to body awareness and equilibrium (Gauchard et al., 2001; Hegeman, 2005; Westlake, 2007). However, there are mixed views as to the exact role that proprioception might play in controlling standing balance, with some researchers arguing that balance training can cause improvements in proprioception (Ribot et al., 1986; Clark et al.,1993; Ashton-Miller et al., 2001; Verhagen et al., 2004). Thirty healthy participants were exposed to thirty threshold to passive movement (TPM) trials (15 inversion and 15 eversion), and six single leg standing trials. Threshold to Passive Movement TPM responses were measured at 0.25 degrees/second in the inversion and eversion direction in thirty participants. Pre and Post to the TPM measures, participants underwent three single leg standing trials on a force plate, with the aim of investigating the relationship between single leg standing balance and ankle proprioception in the inversion and eversion directions. The methodologies chosen for this experiment resulted in a failure to reject the null hypothesis, thus requiring further investigations to begin to fully understand the relationship between proprioception and standing balance.

description: We investigate the strength of the existence of a non-principal ultrafilter over fragments of higher order arithmetic. Let U be the statement that a non-principal ultrafilter exists and let ACA_0^ω be the higher order extension of ACA_0. We show that ACA_0^ω+U is Π^1_2-conservative over ACA_0^ω and thus that ACA_0^ω+\U is conservative over PA. Moreover, we provide a program extraction method and show that from a proof of a strictly Π^1_2 statement \forall f \exists g A(f,g) in ACA_0^ω+U a realizing term in Gödel's system T can be extracted. This means that one can extract a term t, such that A(f,t(f)).

title: Druckmaschinenbau - interdisziplinäre Disziplin
Creators: name: Hars, Christoph
Publisher: name: Roether
Year: 1987

description: "Interdisziplinäre Forschung" ist innerhalb von wenigen Jahren zu einem festen Begriff geworden, weil sie sich als eine sehr erfolgreiche Methode erwiesen hat, Forschung und Entwicklung durch nur scheinbar fachfremde Erkenntnisse und Vorgehensweisen zu befruchten. Dem Autor liegt daran, den Wert interdisziplinärer Fragestellung den heutigen Ingenieuren nahezubringen. Er sieht hier vor allem den Maschinenbauingenieur gefordert und speziell den Druckmaschineningenieur, der sich angesichts der Komplexität einer Druckmaschine besonders vielseitig angesprochen sehen darf. Die wissenschaftlichen Arbeiten, die das Institut für Druckmaschinen und Druckverfahren der Technischen Hochschule Darmstadt unter der zwanzigjährigen Leitung von Professor Karl R. Scheuter geleistet hat und die u. a. in Begriffen wie objektiver Gütegrad eines Druckerzeugnisses, Wirkungsgrad eines Druckprozesses, frequenzmodulierter Bildaufbau u. a. m. ihren wissenschaftlichen Niederschlag gefunden haben, sind beredtes Zeugnis einer erfolgreichen interdisziplinären Vorgehensweise.

description: We report the thermodynamic properties of an ideal boson gas confined in an infinite periodic array of channels modeled by two, mutually perpendicular, Kronig-Penney delta-potentials. The particle's motion is hindered in the x-y directions, allowing tunneling of particles through the walls, while no confinement along the z direction is considered. It is shown that there exists a finite Bose- Einstein condensation (BEC) critical temperature Tc that decreases monotonically from the 3D ideal boson gas (IBG) value $T_{0}$ as the strength of confinement $P_{0}$ is increased while keeping the channel's cross section, $a_{x}a_{y}$ constant. In contrast, Tc is a non-monotonic function of the cross-section area for fixed $P_{0}$. In addition to the BEC cusp, the specific heat exhibits a set of maxima and minima. The minimum located at the highest temperature is a clear signal of the confinement effect which occurs when the boson wavelength is twice the cross-section side size. This confinement is amplified when the wall strength is increased until a dimensional crossover from 3D to 1D is produced. Some of these features in the specific heat obtained from this simple model can be related, qualitatively, to at least two different experimental situations: $^4$He adsorbed within the interstitial channels of a bundle of carbon nanotubes and superconductor-multistrand-wires Nb$_{3}$Sn.

description: Secured opportunistic Medium Access Control (MAC) and complexity reduction in channel estimation are proposed in the Cross layer design Cognitive Radio Networks deploying the secured dynamic channel allocation from the endorsed channel reservation. Channel Endorsement and Transmission policy is deployed to optimize the free channel selection as well as channel utilization to cognitive radio users. This strategy provide the secured and reliable link to secondary users as well as the collision free link to primary users between the physical and MAC layers which yields the better network performance. On the other hand, Complexity Reduction in Minimum Mean Square Errror (CR-MMSE) and Maximum Likelihood (CR-ML) algorithm on Decision Directed Channel Estimation (DDCE) is deployed significantly to achieve computational complexity as Least Square (LS) method. Rigorously, CR-MMSE in sample spaced channel impulse response (SS-CIR) is implemented by allowing the computationally inspired matrix inversion. Regarding CR-ML, Pilot Symbol Assisted Modulation (PSAM) with DDCE is implemented such the pilot symbol sequence provides the significant performance gain in frequency correlation using the finite delay spread. It is found that CRMMSE demonstrates outstanding Symbol Error Rate (SER) performance over MMSE and LS, and CR-ML over MMSE and ML.

description: We present the results of our observations of eight magnetic Herbig Ae/Be stars obtained with the X-shooter spectrograph mounted on UT2 at the VLT. X-shooter provides a simultaneous, medium-resolution and high-sensitivity spectrum over the entire wavelength range from 300 to 2500 nm. We estimate the mass accretion rates M_acc of the targets from 13 different spectral diagnostics using empiric calibrations derived previously for T Tauri-type stars and brown dwarfs. We have estimated the mass accretion rates of our targets, which range from 2x10^-9 to 2x10^-7 M_sun/yr. Furthermore, we have found accretion rate variability with amplitudes of 0.10-0.40 dex taking place on time scales from one day to tens of days. Additional future night-to-night observations need to be carried out to investigate the character of M_acc variability in details. Our study shows that the majority of the calibrational relations can be applied to Herbig Ae/Be stars, but several of them need to be re-calibrated on the basis of new spectral data for a larger number of Herbig Ae/Be stars.

description: The use of social network theory and methods of analysis have been applied to different domains in recent years, including public health. The complete procedure for carrying out a social network analysis (SNA) is a time-consuming task that entails a series of steps in which the expert in social network analysis could make mistakes. This research presents a multi-domain knowledge model capable of automatically gathering data and carrying out different social network analyses in different domains, without errors and obtaining the same conclusions that an expert in SNA would obtain. The model is represented in an ontology called OntoSNAQA, which is made up of classes, properties and rules representing the domains of People, Questionnaires and Social Network Analysis. Besides the ontology itself, different rules are represented by SWRL and SPARQL queries. A Knowledge Based System was created using OntoSNAQA and applied to a real case study in order to show the advantages of the approach. Finally, the results of an SNA analysis obtained through the model were compared to those obtained from some of the most widely used SNA applications: UCINET, Pajek, Cytoscape and Gephi, to test and confirm the validity of the model.
Trail formation based on directed pheromone deposition

description: We propose an Individual-Based Model of ant-trail formation. The ants are modeled as self-propelled particles which deposit directed pheromones and interact with them through alignment interaction. The directed pheromones intend to model pieces of trails, while the alignment interaction translates the tendency for an ant to follow a trail when it meets it. Thanks to adequate quantitative descriptors of the trail patterns, the existence of a phase transition as the ant-pheromone interaction frequency is increased can be evidenced. Finally, we propose both kinetic and fluid descriptions of this model and analyze the capabilities of the fluid model to develop trail patterns. We observe that the development of patterns by fluid models require extra trail amplification mechanisms that are not needed at the Individual-Based Model level.
