Primordial Evolution in the Finitary Process Soup

description: A general and basic model of primordial evolution--a soup of reacting finitary and discrete processes--is employed to identify and analyze fundamental mechanisms that generate and maintain complex structures in prebiotic systems. The processes--$ε$-machines as defined in computational mechanics--and their interaction networks both provide well defined notions of structure. This enables us to quantitatively demonstrate hierarchical self-organization in the soup in terms of complexity. We found that replicating processes evolve the strategy of successively building higher levels of organization by autocatalysis. Moreover, this is facilitated by local components that have low structural complexity, but high generality. In effect, the finitary process soup spontaneously evolves a selection pressure that favors such components. In light of the finitary process soup's generality, these results suggest a fundamental law of hierarchical systems: global complexity requires local simplicity.

Microscopic quantum superpotential in N=1 gauge theories

Year: 2007
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We consider the N=1 super Yang-Mills theory with gauge group U(N), adjoint chiral multiplet X and tree-level superpotential Tr W(X). We compute the quantum effective superpotential W_mic as a function of arbitrary off-shell boundary conditions at infinity for the scalar field X. This effective superpotential has a remarkable property: its critical points are in one-to-one correspondence with the full set of quantum vacua of the theory, providing in particular a unified picture of solutions with different ranks for the low energy gauge group. In this sense, W_mic is a good microscopic effective quantum superpotential for the theory. This property is not shared by other quantum effective superpotentials commonly used in the literature, like in the strong coupling approach or the glueball superpotentials. The result of this paper is a first step in extending Nekrasov's microscopic derivation of the Seiberg-Witten solution of N=2 super Yang-Mills theories to the realm of N=1 gauge theories.

description: Was ist neu? Was kann neu sein? Wie wollen wir das Neue gestalten oder Altes adaptieren? Mit diesen Fragen beschäftigen wir – die Mitglieder der Jungen Akademie und unsere Geschäftsstelle – uns bei allen Treff en, implizit oder explizit. Im Wissenschaftler-Alltag lesen (und schreiben) wir in nahezu jedem Antrag, jeder Rezension, jedem Artikel, dass Unerforschtes dringend zu untersuchen sei, und dass wir dies tun. Aber ist Avantgarde überhaupt noch möglich? Das versuchen wir, im Dossier des Junge Akademie Magazins (JAM) herauszufinden. Ganz neu ist sie nicht mehr, dafür aber in permanenter Regeneration: Die Junge Akademie (JA) feiert in diesem Jahr ihr 15-jähriges Bestehen. Die Festveranstaltung im Juni 2015 in Berlin befasste sich – auch deshalb – mit Institutionen. Jürgen Kaube, Mitherausgeber der Frankfurter Allgemeinen Zeitung und Mitglied im Rat der Jungen Akademie, hielt den Festvortrag: „Forever Young oder Gibt es einen Jugendstil in der Wissenschaft?“. Wir dokumentieren seine Rede im Dossier – drei Mitglieder der Jungen Akademie antworten in kurzen Repliken auf Kaubes ebenso vergnügliche wie nachdenklich stimmende Gedanken. Und auch das Junge Akademie Magazin regeneriert sich: Nach vier Jahren gebe ich als Chefredakteurin das JAM ab, da ich im Sommer 2016 nach fünf viel zu schnell vergehenden Jahren als Mitglied der JA ausscheiden muss. Tobias J. Erb wird das JAM weiterführen. 2011 und 2012 konzipierten wir das Magazin neu, führten das Dossier ein und gestalteten ein neues Layout. Über Ecken erfuhr ich immer wieder, wie gut unser Magazin ankommt: bei Direktoren von Max-Planck-Instituten, bei Chefredakteuren (populär-) wissenschaftlicher Zeitschriften und weltweit, denn die englische Ausgabe wird in Jungen Akademien von Japan bis Südafrika gelesen. Abonnements haben mittlerweile auch Design-Archive und europäische Nationalbibliotheken abgeschlossen. Ob das Junge Akademie Magazin deshalb Avantgarde ist, weiß ich nicht. Ich weiß aber, dass es sich lohnt, auch im digitalen Zeitalter ein Printmagazin zu gestalten, das von der Leidenschaft lebt, die Welt neu zu sehen und zu entdecken, darüber nachzudenken – und davon zu erzählen.

description: We present observations of probable line-of-sight acceleration of a broad absorption trough of C IV in the quasar SDSS J024221.87+004912.6. We also discuss how the velocity overlap of two other outflowing systems in the same object constrains the properties of the outflows. The Si IV doublet in each system has one unblended transition and one transition which overlaps with absorption from the other system. The residual flux in the overlapping trough is well fit by the product of the residual fluxes in the unblended troughs. For these optically thick systems to yield such a result, at least one of them must consist of individual subunits rather than being a single structure with velocity-dependent coverage of the source. If these subunits are identical, opaque, spherical clouds, we estimate the cloud radius to be r = 3.9 10^15 cm. If they are identical, opaque, linear filaments, we estimate their width to be w = 6.5 10^14 cm. These subunits are observed to cover the Mg II broad emission line region of the quasar, at which distance from the black hole the above filament width is equal to the predicted scale height of the outer atmosphere of a thin accretion disk. Insofar as that scale height is a natural size scale for structures originating in an accretion disk, these observations are evidence that the accretion disk can be a source of quasar absorption systems. Based on data from ESO program 075.B-0190(A).

Spatial scales of geomagnetically induced currents in B.C. Hydro's power transmission system
Creators: name: Butler, David Buchanan
Publisher: name: University of British Columbia
Year: 2010

description: Geomagnetically Induced Currents (GIC's) in B. C. Hydro's 500 kV transmission system have in the past been responsible for the generation of harmonics of 60 Hz, system voltage drops, and misoperation of relay units. Characterization of the associated magnetic storms' spatial scales would further the understanding of GIC generation in the area, and allow advanced warning of potential problems in future power transmission projects. Data collected in 1984 at four substations were analysed to determine lateral variations in geomagnetically induced earth surface electric fields. Inversion techniques were employed to find a variety of solutions that would reproduce the data. Results suggested that the magnetic storms were larger than the area monitored, and that resultant electric fields seen by a large portion of the transmission grid were uniform. Departures from this uniformity in other portions of the electric field models were felt either to be due to earth induction effects, or in some cases, to be artifacts of the data analysis techniques. An experiment designed to determine the controlling factors behind GIC's is outlined. Considerable effort would be required to explicitly determine all electric fields affecting the transmission system
Avoiding Rotated Bitboards with Direct Lookup

Year: 2007
Subjects: subject: Data Structures and Algorithms (cs.DS)

description: This paper describes an approach for obtaining direct access to the attacked squares of sliding pieces without resorting to rotated bitboards. The technique involves creating four hash tables using the built in hash arrays from an interpreted, high level language. The rank, file, and diagonal occupancy are first isolated by masking the desired portion of the board. The attacked squares are then directly retrieved from the hash tables. Maintaining incrementally updated rotated bitboards becomes unnecessary as does all the updating, mapping and shifting required to access the attacked squares. Finally, rotated bitboard move generation speed is compared with that of the direct hash table lookup method.

description: In this deliverable document, we report on the activities in task 6.4 - Training Programme, describe the CINECA training activities in the first 24 months of the project and provide the Training Plan for the next 12-24 months. As with the first 12 months of the CINECA project, many of the training efforts for the second 12 months also focused on internal learning opportunities and knowledge exchanges. However, all the training and outreach events have been heavily impacted by COVID-19, which removed our ability to hold face-to-face workshops and staff exchanges.  For training interventions targeted at a broader audience, we have set up a webinar series, providing quarterly online learning interventions. We ran a total of 6 webinars (3 of these webinars in 2019, and 3 in 2020), with 23 attendees on average, 68% on average of those who registered. In addition, a series of short training videos (https://www.cineca-project.eu/short-videos) was created to facilitate the uptake of CINECA outputs. Eight short videos were produced by work packages on different topics. To increase engagement, the short videos were submitted to ELIXIR’s training portal and disseminated via CINECA’s various communication channels.
Finite-size scaling for the left-current correlator with non-degenerate quark masses

description: We study the volume dependence of the left-current correlator with non-degenerate quark masses to next-to-leading order in the chiral expansion. We consider three possible regimes: all quark masses are in the $ε$-regime, all are in the $p$-regime and a mixed-regime where the lighest quark masses satisfy $m_v ΣV \leq 1$ while the heavier $m_s ΣV \gg 1$. These results can be used to match lattice QCD and the Chiral Effective Theory in a large but finite box in which the Compton wavelength of the lightest pions is of the order of the box size. We consider both the full and partially-quenched results.

description: What is new? What can be new? How do we want to shape the new or adapt the old? These are the questions that we – the members of the Junge Akademie and our head office – deal with both implicitly and explicitly during all of our meetings. In our daily lives as researchers, we read (and write) in almost every application, every review, and every article that the uncharted must urgently be investigated, and that we must be the ones to do it. But is the avant-garde even possible anymore? That topic is at the heart of this issue of the Junge Akademie Magazin (JAM). The Junge Akademie is no longer brand new, but nevertheless undergoing constant regeneration: this year marks the 15th anniversary of the academy’s founding. In part due to this occasion, the celebration in Berlin in June 2015 revolved around the topic of institutions. Jürgen Kaube, co-editor of the Frankfurter Allgemeine Zeitung and member of the board of the Junge Akademie, gave the keynote speech: ‘Forever Young or Is There a Jugendstil in Academia?’ We present his speech in this issue. The Junge Akademie Magazin is also undergoing a regeneration process: after four years as editor-in-chief of JAM, I am stepping down from the position, as my membership in the JA will come to an end in the summer of 2016 after fi ve years that have passed all too quickly. Tobias J. Erb will take up the reins at JAM. In 2011 and 2012 we worked together to create a new design for the magazine, which led to the creation of the Dossier section and a new layout. The news of the success of the magazine has come to my ears again and again: imparted to me by directors of Max-Planck-Institutes, by editors-in-chief of (popular) academic magazines, and from readers around the world, as the English edition is read in Young Academies everywhere from Japan to South Africa. Even design archives and national libraries in various European countries are now among JAM’s subscribers. Whether that is enough to make the Junge Akademie Magazin avant-garde is not something I can judge. What I do know is that even in this digital age, it is worthwhile to produce a printed publication that draws its strength from a passionate urge to see the world in new ways, to explore it and think about it – and to tell stories about these explorations.

Gravitino Cosmology Helped by a Right Handed (S)Neutrino

description: In this paper, we discuss interesting scenarios resulting from the interplay between the gravitino and the lightest right-handed (s)neutrino. We consider two gravitino mass regimes vastly separated, that is, $m_{3/2}=\mathcal{O}(100){\rm eV}$ and $m_{3/2}\simeq100{\rm GeV}$. For the former case, a significant amount of the entropy production in the cosmological history to dilute the gravitino relic abundance is unavoidable for consistency with the number of satellite galaxies in the Milky way. We will show that the right-handed (s)neutrino can play the role of the heavy particle whose late time decay provides such an additional radiation. For the later case, the gravitino of $m_{3/2}\simeq100{\rm GeV}$ may resolve the $S_{8}$ tension as a decaying dark matter. We will show how the lightest right-handed neutrino and its superpartner can help the gravitino decaying dark matter be equipped with a long enough life time and mass degeneracy with a massive decay product to address the $S_{8}$ tension.

description: We study Mott insulator - superfluid transition in a two-band boson Hubbard model, which can be mapped onto a spin-1/2 XY model with spins coupled to an additional Ising degree of freedom. By using a modified mean field theory that include the effects of phase fluctuations, we show that the transition is first order at both zero and finite temperatures. On the Mott insulator side, there may be reentrance in phase transition. These features are consequences of the underlying transition between competing defect poor and defect rich phases. The relevance of the model and our results to supersolid 4He and cold bosonic atoms in optical lattices are discussed.

description: We investigate weak localization in metallic networks etched in a two dimensional electron gas between $25\:$mK and $750\:$mK when electron-electron (e-e) interaction is the dominant phase breaking mechanism. We show that, at the highest temperatures, the contributions arising from trajectories that wind around the rings and trajectories that do not are governed by two different length scales. This is achieved by analyzing separately the envelope and the oscillating part of the magnetoconductance. For $T\gtrsim0.3\:$K we find $\Lphi^\mathrm{env}\propto{T}^{-1/3}$ for the envelope, and $\Lphi^\mathrm{osc}\propto{T}^{-1/2}$ for the oscillations, in agreement with the prediction for a single ring \cite{LudMir04,TexMon05}. This is the first experimental confirmation of the geometry dependence of decoherence due to e-e interaction.

Curie temperature of the two band double exchange model for manganites

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We consider two-band double exchange model and calculate the critical temperature in ferromagnetic regime (Curie temperature). The localized spins are represented in terms of the Schwinger-bosons, and two spin-singlet Fermion operators are introduced. In terms of the new Fermi fields the on-site Hund's interactions are in a diagonal form and one accounts for them exactly. Integrating out the spin-singlet fermions we derive an effective Heisenberg type model for a vector which describes the local orientations of the total magnetization. The transversal fluctuations of the vector are the true magnons in the theory, which is a base for Curie temperature calculation. The critical temperature is calculated employing the Schwinger-bosons mean-field theory. While approximate, this technic of calculation captures the essentials of the magnon fluctuations in the theory, and for 2D systems one obtains zero Curie temperature, in accordance with Mermin-Wagner theorem.

Constraint of systematic uncertainties in an electron neutrino search

description: MicroBooNE is a liquid argon time projection chamber which has been
      running in the Booster Neutrino Beam at Fermilab since 2015. The primary
      goal of MicroBooNE is investigation of the excess of electromagnetic
      events observed by the MiniBooNE collaboration. Due to limitations of the
      Cherenkov-based particle identification of MiniBooNE, this excess could be
      interpreted as either photon-like or electron-like. A photon-like excess
      would indicate that there are processes which are not well understood
      which could act as a background in neutrino oscillation measurements,
      while an electron-like excess could indicate the presence of sterile
      neutrinos, the existence of which is one of the most hotly debated
      questions in the field.

      This work will outline the MicroBooNE strategy for investigation of this
      low-energy excess, with particular attention given to
      the role of the muon neutrino sideband which is used as an important
      constraint on systematic uncertainties. A procedure has been developed in
      order to apply this constraint to an electron neutrino dataset, and it has
      been shown that the constraint results in an improvement to the
      sensitivity.

      In order to perform this constraint, an exclusive-state νμ CC selection
      has been developed, which results in 804 selected events from on-beam
      data. The ratio of the data with respect to simulation is R=0.78 ± 0.04
      (stat.) ± 0.12 (syst.).

      In addition, this thesis presents a first measurement of the longitudinal
      ionisation electron diffusion coefficient from the MicroBooNE data, which
      is determined to be 3.73 (+0.70, -0.68) cm2/s.

Religiousness and preoperative anxiety: a correlational study
Creators: name: Karimollahi, Mansoureh
Publisher: name: figshare
Year: 2021
Subjects: Health Care

description: Background: Major life changes are among factors that cause anxiety, and one of these changes
is surgery. Emotional reactions to surgery have specific effects on the intensity and velocity as well
as the process of physical disease. In addition, they can cause delay in patients recovery. This study
is aimed at determining the relationship between religious beliefs and preoperative anxiety.
Methods: This survey is a correlational study to assess the relationship between religious beliefs
and preoperative anxiety of patients undergoing abdominal, orthopaedic, and gynaecologic surgery
in educational hospitals. We used the convenience sampling method. The data collection
instruments included a questionnaire containing the Spielberger State-Trait Anxiety Inventory
(STAI), and another questionnaire formulated by the researcher with queries on religious beliefs
and demographic characteristics as well as disease-related information. Analysis of the data was
carried out with SPSS software using descriptive and inferential statistics. Results were arranged in
three tables.
Results: The findings showed that almost all the subjects had high level of religiosity and moderate
level of anxiety. In addition, there was an inverse relationship between religiosity and intensity of
anxiety, though this was not statistically significant.
Conclusion: The results of this study can be used as evidence for presenting religious counselling
and spiritual interventions for individuals undergoing stress. Finally, based on the results of this
study, the researcher suggested some recommendations for applying results and conducting
further research.
Towards Low-Photon Nanoscale Imaging: Holographic Phase Retrieval via Maximum Likelihood Optimization

description: A new algorithmic framework is presented for holographic phase retrieval via maximum likelihood optimization, which allows for practical and robust image reconstruction. This framework is especially well-suited for holographic coherent diffraction imaging in the \textit{low-photon regime}, where data is highly corrupted by Poisson shot noise. Thus, this methodology provides a viable solution towards the advent of \textit{low-photon nanoscale imaging}, which is a fundamental challenge facing the current state of imaging technologies. Practical optimization algorithms are derived and implemented, and extensive numerical simulations demonstrate significantly improved image reconstruction versus the leading algorithms currently in use. Further experiments compare the performance of popular holographic reference geometries to determine the optimal combined physical setup and algorithm pipeline for practical implementation. Additional features of these methods are also demonstrated, which allow for fewer experimental constraints.

description: Additional file 1: Figure S1. Due to density-based clustering of ICA run with randomized restarts, the number of robust components do not directly correlate with the selected dimensionality. Figure S2. Across all dimensions components revealed in the final decomposition were found to be well conserved at the established threshold. All components in the final decomposition were correlated pairwise with those of all preceding decompositions. Once a component present in the final decomposition was calculated at a lower dimension that component continued to persist within decompositions of higher dimensionality. A component in the final decomposition was said to be present in a particular decomposition where its correlation with a component in that decomposition was above the established threshold. Across all datasets, PRECISE 1.0, PRECISE 2.0, B. subtilis, and StaphPRECISE, components were found to be well conserved, rarely dropping below their established threshold once computed at a lower dimension. PRECISE 1.0 shown here for example. Figure S3. Components from the final, fully decomposed dataset were correlated pairwise with components of all preceding decompositions. Histograms of the highest correlations for each component across all dimensions were plotted for (A) PRECISE 1.0, (B) PRECISE 2.0, (C) B. subtilis, and (D) StaphPRECISE. The elbow point of these highly correlated values served as the threshold to classify a particular component as conserved.

description: We discuss the properties of the collective modes of a system composed by a thermalized quark-gluon plasma traversed by a relativistic jet of partons. The transport equations obeyed by the components of the plasma and of the jet are studied in the Vlasov approximation. Assuming that the partons in the jet can be described with a tsunami-like distribution function we derive the expressions of the dispersion law of the collective modes. Then the behavior of the unstable gauge modes of the system is analyzed for various values of the velocity of the jet, of the momentum of the collective modes and of the angle between these two quantities. We find that the most unstable modes are those with momentum orthogonal to the velocity of the jet and that these instabilities appear when the velocity of the jet is higher than a threshold value, which depends on the plasma and jet frequencies. The results obtained within the Vlasov approximation are compared with the corresponding results obtained using a chromohydrodynamical approach.The effect we discuss here suggests a possible collective mechanism for the description of the jet quenching phenomena in heavy ion collisions.

description: When looking for a solution, deterministic methods have the enormous advantage that they do find global optima. Unfortunately, they are very CPU-intensive, and are useless on untractable NP-hard problems that would require thousands of years for cutting-edge computers to explore. In order to get a result, one needs to revert to stochastic algorithms, that sample the search space without exploring it thoroughly. Such algorithms can find very good results, without any guarantee that the global optimum has been reached; but there is often no other choice than using them. This chapter is a short introduction to the main methods used in stochastic optimization.

On the Lagrangian-Eulerian Coupling in the Immersed Finite Element/Difference Method

description: The immersed boundary (IB) method is a non-body conforming approach to fluid-structure interaction (FSI) that uses an Eulerian description of the momentum, viscosity, and incompressibility of a coupled fluid-structure system and a Lagrangian description of the deformations, stresses, and resultant forces of the immersed structure. Integral transforms with Dirac delta function kernels couple the Eulerian and Lagrangian variables, and in practice, discretizations of these integral transforms use regularized delta function kernels. Many different kernel functions have been proposed, but prior numerical work investigating the impact of the choice of kernel function on the accuracy of the methodology has been limited. This work systematically studies the effect of the choice of regularized delta function in several FSI benchmark tests using the immersed finite element/difference (IFED) method, which is an extension of the IB method that uses a finite element structural discretizations combined with a Cartesian grid finite difference method for the incompressible Navier-Stokes equations. The IFED formulation evaluates the regularized delta function on a collection of interaction points that can be chosen to be denser than the nodes of the Lagrangian mesh, and this study investigates the effect of varying the relative mesh widths of the Lagrangian and Eulerian discretizations. Our results indicate that kernels satisfying a commonly imposed even-odd condition require higher resolution to achieve similar accuracy as kernels that do not satisfy. We also find that narrower kernels are more robust and that structural meshes that are substantially coarser than the Cartesian grid can yield high accuracy for shear-dominated cases but not for cases with large normal forces. We verify our results in a large-scale FSI model of a bovine pericardial bioprosthetic heart valve in a pulse duplicator.

description: This article introduces a natural extension of colouring numbers of knots, called colouring polynomials, and studies their relationship to Yang-Baxter invariants and quandle 2-cocycle invariants. For a knot K in the 3-sphere let π_K be the fundamental group of the knot complement, and let (m_K,l_K) be a meridian-longitude pair in π_K. Given a finite group G and an element x in G, we consider the set of representations ρfrom π_K to G that map the meridian m_K to x, and define the colouring polynomial P(K) as the sum over all longitude images ρ(l_K). The resulting invariant maps knots to the group ring Z[G]. It is multiplicative with respect to connected sum and equivariant with respect to symmetry operations of knots. Examples are given to show that colouring polynomials distinguish knots for which other invariants fail, in particular they can distinguish knots from their mutants, obverses, inverses, or reverses. We prove that every quandle 2-cocycle state-sum invariant of knots is a specialization of some knot colouring polynomial. This provides a complete topological interpretation of these invariants in terms of the knot group and its peripheral system. Furthermore, we show that P can be presented as a Yang-Baxter invariant, i.e. as the trace of some linear braid group representation. This entails in particular that Yang-Baxter invariants can detect non-inversible and non-reversible knots.

description: Two approaches for closing the turbulence subgrid-scale stress tensor in terms of matrix exponentials are introduced and compared. The first approach is based on a formal solution of the stress transport equation in which the production terms can be integrated exactly in terms of matrix exponentials. This formal solution of the subgrid-scale stress transport equation is shown to be useful to explore special cases, such as the response to constant velocity gradient, but neglecting pressure-strain correlations and diffusion effects. The second approach is based on an Eulerian-Lagrangian change of variables, combined with the assumption of isotropy for the conditionally averaged Lagrangian velocity gradient tensor and with the `Recent Fluid Deformation' (RFD) approximation. It is shown that both approaches lead to the same basic closure in which the stress tensor is expressed as the product of the matrix exponential of the resolved velocity gradient tensor multiplied by its transpose. Short-time expansions of the matrix exponentials are shown to provide an eddy-viscosity term and particular quadratic terms, and thus allow a reinterpretation of traditional eddy-viscosity and nonlinear stress closures. The basic feasibility of the matrix-exponential closure is illustrated by implementing it successfully in Large Eddy Simulation of forced isotropic turbulence. The matrix-exponential closure employs the drastic approximation of entirely omitting the pressure-strain correlation and other `nonlinear scrambling' terms. But unlike eddy-viscosity closures, the matrix exponential approach provides a simple and local closure that can be derived directly from the stress transport equation with the production term, and using physically motivated assumptions about Lagrangian decorrelation and upstream isotropy.

Dietrich); 1 ♁, 2 ♀, Illinois, Calumet, 41°41'48" N, 87°34'22" W, 3 IX 2003 (Dmitriev). Description. Coloration yellowish green without color pattern. Body length 5.2– 5.9 mm; head width 1.4 mm. Notes. An unidentified nymph of Chlorotettix from Argentina has two brown broad longitudinal stripes with washed out lateral margins; macrochaetae on abdomen and legs dark, with dark setal areolae. Th e nymph of Ch. meriscus Cwikla was illustrat- ed by Cwikla (1988). Th e tribal placement of the genus Chlorotettix requires further investigation. The nymphs of this genus have a long pygofer, which is not characteristic for the tribe Athysanini. Chlorotettix shares some characters with the new tribe Pendarini (long pygofer), although the former has the crown-face transition rounded, longer abdominal macrochaetae and different color pattern.

description: We develop a topological model of knots and links arising from a single (or multiple processive) round(s) of recombination starting with an unknot, unlink, or (2,m)-torus knot or link substrate. We show that all knotted or linked products fall into a single family, and prove that the size of this family grows linearly with the cube of the minimum number of crossings. Additionally, we prove that the only possible products of an unknot substrate are either clasp knots and links or (2,m)-torus knots and links. Finally, in the (common) case of (2,m)-torus knot or link substrates whose products have minimal crossing number m+1, we prove that the types of products are tightly prescribed, and use this to examine previously uncharacterized experimental data.

Coastal upwelling along the west coast of Vancouver Island
Creators: name: Jardine, Ian David
Publisher: name: University of British Columbia
Year: 2010

description: Wind-driven up welling events near Brooks Peninsula off the west coast of Vancouver Island have been identified during the summers of 1988 and 1989 from sea surface NOAA AVHRR thermal imagery obtained at the UBC Satellite Oceanography and Meteorology Laboratory. Software has been developed to characterize the strength and extent of the surface cooling associated with the upwelling. A two-dimensional, 2-layer finite difference model with 1 km resolution has been formulated to examine the small-scale dynamics of the upwelling events. The model uses local wind and includes realistic coastline and bathymetry. The wind-stress and coastline configuration appear to be the main factors contributing to favourable upwelling regions. The results of the model compare favourably to the observed starting location of the upwelling.
