description: Climate change, rapid urbanization, and autonomous vehicles are a few examples of the forces change that will have a significant impact on the projects that landscape architects will touch. The influence of these forces on our world remains unknown, and urban futures remain speculative. While the problems of climate change appear dire, present an opportunity for the landscape architecture discipline to engage in new scales of design. However, as designers are forced to engage with complex design problems of the contemporary era, the field now requires new forms of design methodology. Architects and Landscape Architects in the field have begun to employ a new methodology, scenario planning, to provide a framework for how to design in these disruptive conditions and help frame design solutions for an unknown future. This project proposal first seeks to understand the scenario planning methodology. Then it explores the application of the scenario method in the field of landscape architecture. Finally, a design project is proposed for the Lower Fraser River in Metro Vancouver, which seeks to design for an extreme climate future, envisioning the futures of this region at risk.

Etude exploratoire
Filière plant de pomme de terre

description: L’objectif de l’étude exploratoire est d’identifier des pistes de recherche et d’innovation qui permettraient de développer une gestion plus globale des virus sur la sélection de plant de pomme de terre pour l’agriculture biologique, qui prendrait en compte tous les éléments écosystémiques.
 Les résultats et les perspectives qui se sont dégagés sont nombreuses et ne peuvent pas être toutes énumérées ici. Les résultats ont permis d’identifier 5 systèmes de production, n’ayant pas accès ou ne voulant pas faire partie du système de production basé sur l’in vitro et les tests sérologiques. En s’inspirant de ces systèmes il a été souligné l’importance des inters relations entre les pathogènes, l’environnement et la plante pendant le processus de sélection. Il a été dégagé des perspectives et des pistes de recherche qui permettront à l’ITAB, de réaliser des essais. Cette étape de recherche exploratoire préalable était indispensable.
 C’est maintenant aux acteurs de se saisir de la question, de décider des enjeux et de la démarche à suivre, sachant, avec notamment le réchauffement climatique, que les conditions environnementales vont évoluer et être plus favorables à la transmission des virus. Il serait donc pertinent d’entrevoir une approche différente de la gestion des viroses sur la sélection des plants de pommes de terre français. The objective of the exploratory study is to identify avenues for research and innovation that would make it possible to develop a more global management of viruses in the selection of potato plants for organic agriculture, taking into account all ecosystem elements.
 The results and perspectives that have emerged are numerous and cannot all be listed here. The results identified 5 production systems, having access or not wanting to be part of the in vitro based production system. Drawing on these systems, the importance of the interrelationships between pathogens, the environment and the plant during the selection process was stressed. Identifying issues and assumptions that will allow the ITAB to conduct tests. This stage of preliminary exploratory research was essential.
 It is now up to the actors to take up the issue, to decide on the stakes and the approach to follow, knowing, with global warming in particular, that environmental conditions will evolve and be more favourable to the transmission of viruses. It would therefore be relevant to envisage a different approach to virus disease management on the selection of French seed potatoes.

In the latter case we show that the full shift symmetry of the brane coordinates, which is abelian in the rigid limit, is partially distorted by bulk fields to a nilpotent algebra.

description: The first search for scalar leptoquarks produced in $τ$-lepton-quark collisions is presented. It is based on a set of proton-proton collision data recorded with the CMS detector at the LHC at a center-of-mass energy of 13 TeV corresponding to an integrated luminosity of 138 fb$^{-1}$. The reconstructed final state consists of a jet, significant missing transverse momentum, and a $τ$ lepton reconstructed through its hadronic or leptonic decays. Limits are set on the product of the leptoquark production cross section and branching fraction and interpreted as exclusions in the plane of the leptoquark mass and the leptoquark-$τ$-quark coupling strength.

description: In this work we study the production of $K^*(4307)$ in $B$ decays by determining the $J/ψπ^{+(0)}K^{0}$ and $J/ψπ^- K^+$ invariant mass distributions of the processes $B^+\to J/ψπ^+π^0 K^0$ and $B^+\to J/ψπ^+π^- K^+$, respectively. Such $K^*(4307)$ has been recently predicted as a three-body state originated from the dynamics involved in the $K D\bar D^*$ system, with the $KD$ subsystem forming the $D^{*}_{s0}(2317)$ in isospin 0, and the $D\bar D^*$ subsystem generating the $X(3872)$ in isospin 0 and the $Z_c(3900)$ in isospin 1. The hidden charm content of $K^*(4307)$ favors its decay to a state like $J/ψπK$ and the study of $B$-decays with these particles in their final states can constitute a way of finding experimental evidences for such an exotic vector meson, whose width, in spite of its large mass, is still quite narrow (around 18 MeV).

description: We study a superconducting Kitaev ring pierced by a magnetic flux, with and without disorder, in a quantum ring configuration, and in a rf-SQUID one, where a weak link is present. In the rf-SQUID configuration, in the topological phase, the supercurrent shows jumps at specific values of the flux $Φ^*=\frac{hc}{e}(1/4+n)$, with $n\in\mathbb{N}$. In the thermodynamic limit $Φ^*$ is constant inside the topological phase, independently of disorder, and we analytically predict this fact using a perturbative approach in the weak-link coupling. The weak link breaks the topological ground-state degeneracy, and opens a spectral gap for $Φ\neq Φ^*$, that vanishes at $Φ^*$ with a cusp providing the current jump. Looking at the quasiparticle excitations, we see that they are Anderson localized, so they cannot carry a resistive contribution to the current, and the localization length shows a peculiar behavior at a flat-band point for the quasiparticles. In the absence of disorder, we analytically and numerically find that the chemical-potential derivative of the supercurrent logarithmically diverges at the topological-to-trivial transition, in agreement with the transition being of the second order.

Dialectical behavior therapy skills utilization: a three-month follow-up study on clinical outcomes
Creators: name: Yin, Qingqing
Publisher: name: No Publisher Supplied
Year: 2021

description: Ample research supports skills training of Dialectical Behavior Therapy (DBT) to be a critical mode of treatment, though gaps remain in our understanding of the effects of actual skills utilization outside of treatment at longer-term follow-ups. The current study involved 60 adults from around the U.S. receiving comprehensive DBT in-person or via telehealth. Participants completed an online registration survey assessing their mental health, daily reports of DBT skills use for three weeks, and a follow-up survey reassessing mental health three months later. The objectives were to examine if frequency of DBT skills use by comprehensive DBT clients predicts improvements in their mental health at follow-up and whether the four different DBT skills modules differentially impact these outcomes. Results suggested that greater number of days of skills use per week was associated with fewer difficulties in work and social adjustment at follow-up, while accounting for baseline functioning. Number of days of overall skills use per week was not associated with other outcomes, such as borderline personality disorder (BPD) symptom, anxiety, or depression severity, or adaptive or maladaptive ways of coping. Controlling for all other modules, clients who used Interpersonal Effectiveness (IE) skills on more days per week reported fewer difficulties in work and social functioning, and lower BPD and depression symptom severity and anger. No significant associations were found between the three other modules and any outcomes. These findings highlighted improvements in social-related functioning among DBT clients who endorsed greater overall skills use, and the potentially unique effects of IE skills on treatment outcomes.

description: The EU legislation on organic farming was aimed at forcing the use of organic seeds in organic production. However, there are striking differences in its implementation across the EU and the use of organic seeds is still sparse. This study examines the use of organic seeds for sweet pepper (Capsicum annuum L.) production in a pilot study for the Netherlands and Spain. In order to identify existing incentives and constraints, a supply chain analysis is applied, derogation requests for using non-organic seeds are analysed and interviews with stakeholders of the supply chain are conducted. Based on the findings, recommendations are given on how each stakeholder can participate in improving the implementation of the EU law, promoting the use of organic seeds.

description: No abstracts are to be cited without prior reference to the author.North Sea cod (Gadus morhua) is outside safe biological limits and total allowable catch (TAC) management has proved ineffective to rebuild the stock. The European Commission is considering to impose a discard ban to preserve vulnerable and economically important fish stocks. We explore the potential effects of a discard ban in mixed fisheries management using the French mixed fisheries in the Eastern English Channel as a model system. We examine in particular the performance of two different management scenarios, (i) individual quota management with a tolerance for discarding and, (ii) individual quota management in combination with a discard ban, using a dynamic state variable model. The model evaluates a time series of decisions taken by fishers to maximize profits within management constraints. Compliance to management was tested by applying an in height varying fine for exceeding the quota. We then evaluate the consequences of individual cod quota in both scenarios, with respect to over-quota discarding, spatial and temporal effort allocation and switching between métiers. Individual quota management without a discard ban hardly influenced fishers’ behaviour, as they could fully utilise cod quota and continue fishing other species while discarding cod. In contrast, a discard ban forced fishers to reallocate effort to areas and weeks where cod catch is low, at the expense of lower revenue. In general, a restrictive policy for individual quota for cod needs to be combined with a discard ban and a high fine (> 20 times the sale price) to reduce over-quota discarding.
Comment on ``Strangelets as Cosmic Rays beyond the Greisen-Zatsepin-Cuzmin Cutoff''

description: Madsen and Larsen proposed (astro-ph/0211597) that strangelets - stable lumps of strange quark matter (SQM) - are candidates for the highest energy cosmic rays. They point out that the expected properties of strangelets make them easier to accelerate and less prone to energy losses than protons or ions. The purpose of this Comment is to point out that if ultra-high-energy cosmic rays (UHECRs) are indeed strangelets, their flux would guarantee that all neutron stars must be strange quark (SQ) stars, while no ``conventional'' (i.e., composed of nucleons and other baryons) neutron stars can coexist. This seems highly unlikely in view of various observed phenomena in neutron stars.

title: The Penetration of Solar Radiation in Martian Ice Analogues
Creators: name: Chinnery, Hannah Elizabeth
Publisher: name: The Open University
Year: 2020

description: The penetration depth of broad spectrum solar radiation (300 nm – 1100 nm) in ices relevant to Mars has been measured in the laboratory for the first time. These ices include carbon dioxide and water ices in the form of slab ice, ice of controlled grain sizes, and snow. All of these ice morphologies are observed on the surface of Mars today, and whilst some measurements of water ice have been made for terrestrial applications, many of these cannot be directly compared to carbon dioxide ice because of factors such as impurities in naturally occurring ice, or measurements covering only a narrow spectral range.

 The results presented here show that the penetration depth varies with both grain size and ice composition. Grain size (due to light scattering) is the dominant parameter at particle radii applicable to snow, and composition (therefore material-specific optical properties) dominates in larger grains and slab ice. An empirical model is presented, which can be used to predict penetration depth of a specific grain size and composition of ice. This has important applications for modelling surface processes on Mars, many of which have no terrestrial analogue. Relevant features include araneiforms, observed only in association with the seasonal carbon dioxide slab ice, or gullies, which vary in morphology depending on location, indicating varying formation mechanisms. By using more accurate penetration depths for ices on the Martian surface, radiative transfer models describing surface-atmosphere interactions could better simulate these formation processes.

 These results can further be applied to modelling icy moons and comets. Future work to expand on this thesis would involve determining the effect of impurities on the e-folding scale of CO2 ice as Mars’s seasonal polar caps contain <0.1% dust. Moreover, measuring the penetration depth in other extra-terrestrial ices would be benefit studies of comets and icy moons.

description: White lupin (Lupinus albus) is an interesting crop for use as food, feed, forage or cover crop. However, its cultivation is currently limited because of its high susceptibility to the seed-borne pathogen Colletotrichum lupini, causal agent of lupin anthracnose. Twenty-eight seed treatments were studied here for their efficacy against lupin anthracnose, consisting of 4 hot water, 5 steam, 4 dry heat, 5 electron, 2 plant-based and 2 microbial treatments, as well as 6 controls. Experiments were divided into a germination assay and a pot-based disease assessment experiment. Treatment effects were studied by visual assessments of plants, culture-based incubation of plant tissue and quantitative polymerase chain reaction (qPCR)-based detection of Colletotrichum spp. in plants. Only the sodium hypochlorite control significantly impaired germination rate, normal germination rate and early vigour of seedlings. Culture-based incubation of epicotyl samples from 1.5-week old seedlings revealed significant treatment effects on the overall seed microbiome. No significant treatment effects were observed for plant vitality scores, percentage of diseased leaves and plant biomass at harvest. Colletotrichum spp. was detected in epicotyl samples of 1.5-week old seedlings and in shoot samples of 7.5-week old plants, but no significant treatment effects were observed. Absence of treatment effects could be due to insufficient power of the tested treatments, or to insufficient pathogen levels in the plants. No characteristic anthracnose symptoms were observed, and it is possible that the initial seed inoculum level was too low to lead to sufficient disease pressure in the plants. Nevertheless, the steam treatments significantly reduced the overall seed microbiome, and no Colletotrichum spp. was detected in seedlings or grown shoots, indicating a potential efficacy of the steam treatments against lupin anthracnose. The treatments dry heat 75°C/5h, electron at penetration depth 3 and intensity 3, and thyme oil also showed slight indications of efficacy against lupin anthracnose.

description: The most detailed constructions of microstate geometries, and particularly of superstrata, are done using $\mathcal{N} = (1,0)$ supergravity coupled to two anti-self-dual tensor multiplets in six dimensions. We show that an important sub-sector of this theory has a consistent truncation to a particular gauged supergravity in three dimensions. Our consistent truncation is closely related to those recently laid out by Samtleben and Sarioglu (arXiv:1907.08413 [hep-th]), which enables us to develop complete uplift formulae from the three-dimensional theory to six dimensions. We also find a new family of multi-mode superstrata, indexed by two arbitrary holomorphic functions of one complex variable, that live within our consistent truncation and use this family to provide extensive tests of our consistent truncation. We discuss some of the future applications of having an intrinsically three-dimensional formulation of a significant class of microstate geometries.

title: Investigation of Novel Therapies for Hyperammonemia
Creators: name: de Angelis, Angela
Publisher: name: The Open University
Year: 2019

description: Ammonia is a toxic compound daily produced and consumed during cell metabolism in the body. It is converted to the less toxic substance urea by the urea cycle in the liver. Moreover, the urea cycle operates anatomically and functionally in sequence with the hepatic glutamine synthetase (GS) to detoxify ammonia and both systems are required for ammonia homeostasis. Urea cycle or GS deficiencies and liver diseases lead to defective ammonia removal causing hyperammonemia. Hyperammonemia is a life- threatening condition which may results in hepatic encephalopathy and death, if left untreated. Available therapies for hyperammonemia are partially effective and novel and improved therapies are required. Considering the cooperative role of GS in ammonia detoxification, gene therapy based on hepatic GS augmentation was investigated as a potential treatment against hyperammonemia. Thus, upregulation of hepatic GS protects wild-type mice against acute hyperammonemia. Notably, liver specific GS overexpression improved ammonia detoxification also in Cps1-deficient mice. As a result, hepatic GS augmentation therapy has potential for treatment of both primary and secondary forms of hyperammonemia.

 Furthermore ammonia can induce modification of O-GlcNAcylation levels. O- GlcNAcylation is a dynamic post-translational modification catalyzed by the enzyme O-GlcNAc transferase (OGT) whereas the O-GlcNAcase (OGA) removes O-GlcNAc. O-GlcNAcylation, once modulated, may be a new therapeutic target to treat hyperammonemia. Hence, the role of hepatic O-GlcNAcylation in ammonia detoxification was investigated. In vivo modulation of O-GlcNAcylation through both pharmacological (small molecules) and OGA knockdown approaches improved ammonia detoxification. Neither expression of genes encoding urea cycle enzymes nor protein levels of these enzymes were affected by OGA inhibition, suggesting that hepatic O-GlcNAcylation regulates ammonia clearance capacity by enzymatic activity of the urea cycle. Finally, hepatic O-GlcNAcylation plays an important role in ammonia detoxification. Therefore OGA is a novel therapeutic target for treatment of hyperammonemia of both urea cycle disorders and acquired hyperammonemia.
The Dynamic Present: Unifying Quantum Mechanics and General Relativity through Continuous Present Actualization

Dynamic Present

description: Dynamic Present Theory (DPT) offers a groundbreaking framework aimed at unifying quantum mechanics (QM) and general relativity (GR) by reimagining the concept of time. Instead of perceiving time as a linear progression of past, present, and future, DPT posits that time emerges from Continuous Present Actualization (CPA)—the perpetual transformation of energy in the ever-present "now." In this view, only the present moment truly exists; reality is a constant unfolding governed by immutable mathematical laws.

 

By grounding both QM and GR within the CPA framework, DPT harmoniously integrates the probabilistic nature of quantum phenomena with the deterministic fabric of spacetime described by relativity. This integration addresses longstanding paradoxes such as the measurement problem and quantum non-locality without resorting to mechanisms like wave function collapse or introducing hidden variables. Phenomena like entanglement and gravity are reinterpreted as manifestations of the CPA process, providing coherent explanations that align with empirical observations.

 

Beyond resolving specific physical paradoxes, DPT challenges established scientific paradigms by suggesting that the continuous actualization of the present is fundamental to the universe's structure. This perspective not only reshapes our understanding of time and existence but also opens new avenues for experimental validation and theoretical exploration. By proposing testable predictions and aligning with existing mathematical frameworks, DPT aspires to usher in a new era of scientific discovery, offering a compelling and intuitive pathway toward a unified theory of everything.

description: No abstracts are to be cited without prior reference to the author.Discarding of unwanted or non-mandated catch wastes both food and economic resources, and represents a major source of unaccounted mortality, contributing to the overfishing of stocks. Under growing public and political concern, the European Commission is seeking to reduce unwanted catches and eliminate discarding by 2016. One proposed approach is to implement catch quotas, in which all catches are landed and counted against species specific quotas. The impact of such a management tool on an entire fishing fleet has not been evaluated. We use detailed observer and logbook data to predict the potential impact of catch quotas on fishing mortality and total operating profits for the English North Sea otter trawler fleet. Fishing mortality should be reduced, but initial increases may be observed where the fleet discard rate is lower than the estimate used to derive the catch quotas. The economic benefit of using more selective gear to avoid low value individuals of the catch quota species is likely to be substantially offset by a loss of marketable catch, indicating how fishing behaviour may or may not be altered under catch quotas.

description: A global optimization method, conformational space annealing (CSA), is applied to study a 46-residue protein with the sequence B_9N_3(LB)_4N_3B_9N_3(LB)_5L, where B, L and N designate hydrophobic, hydrophilic, and neutral residues, respectively. The 46-residue BLN protein is folded into the native state of a four-stranded beta-barrel. It has been a challenging problem to locate the global minimum of the 46-residue BLN protein since the system is highly frustrated and consequently its energy landscape is quite rugged. The CSA successfully located the global minimum of the 46-mer for all 100 independent runs. The CPU time for CSA is about seventy times less than that for simulated annealing (SA), and its success rate (100 %) to find the global minimum is about eleven times higher. The amount of computational efforts used for CSA is also about ten times less than that of the best global optimization method yet applied to the 46-residue BLN protein, the quantum thermal annealing with renormalization. The 100 separate CSA runs produce the global minimum 100 times as well as other 5950 final conformations corresponding to a total of 2361 distinct local minima of the protein. Most of the final conformations have relatively small RMSD values from the global minimum, independent of their diverse energy values. Very close to the global minimum, there exist quasi-global-minima which are frequently obtained as one of the final answers from SA runs. We find that there exist two largest energy gaps between the quasi-global-minima and the other local minima. Once a SA run is trapped in one of these quasi-global-minima, it cannot be folded into the global minimum before crossing over the two large energy barriers, clearly demonstrating the reason for the poor success rate of SA.

Creators: name: Wood, Eleni May
Publisher: name: The Open University

description: The Himalayan mountain range is the perfect natural laboratory to ground truth tectonic models of continental collision due to its young age. Evidence for late-stage exhumation of deep (>50 km) orogenic crust in the eastern Himalaya suggests that tectonic processes can rapidly mobilise the lower crust. This thesis presents a detailed metamorphic and petrochronological study of the high-pressure granulite-facies Masang Kang Terrane (MKT) in NW Bhutan. In this study, two different units have been identified within the MKT based on their P-T-t histories. In the northern MKT, the timing of eclogite-facies metamorphism (>17 kbar, ~650°C) is constrained by new zircon and monazite U-Pb ages between ~21-16 Ma. New observations of allanite textures in metabasitic ‘granulitised eclogites’ are used in conjunction with zircon to constrain the timing of the granulite overprint and decompression (750-800°C, 7-9 kbar) at ~15.5 Ma. The first occurrence of a sapphirine-bearing sample in the Himalaya yields a complementary P-T-t history, which supports high-temperature exhumation in the north MKT. Furthermore, inherited monazite & mixed garnet ages provide evidence for Bhimpedian-aged metamorphism at ca. ~500 Ma. In the southern MKT, monazite and garnet in sillimanite-grade metasediments reveal a protracted history between ~40-21 Ma, that includes isobaric heating to granulite-facies in the lower midcrust (~800°C, ~8 kbar). The contrasting P-T-t histories for the two units suggest the presence of a secondary ‘Lumgu’ thrust that juxtaposed the deep- and mid-crust, before final exhumation along the Laya thrust at their base. Similarities between P-T-t histories for the southern MKT and the neighbouring Jomolhari massif suggests that further work needs to be done to constrain the architecture of these terranes.

To account for the effects of Coulomb interaction in the QD-QPC setup operating in the integer quantum Hall regime we describe the edge current in the quantum circuit by Luttinger model characterized by the Luttinger parameter $g$. It is shown that the temperature dependence of both electric conductance $G\propto T^{2/g}$ and thermoelectric coefficient $G_T\propto T^{1+2/g}$ detours from the Fermi-liquid (FL) theory predictions. The behaviour of the thermoelectric power $S=G_T/G\propto T$ in a regime of a single-channel Kondo effect is, by contrast, consistent with the FL paradigm. We demonstrate that the interplay between the mesoscopic Coulomb blockade in QD and weak repulsive interaction in the Luttinger Liquid $g=1-α$ $(α\ll 1)$ results in the enhancement of the thermopower. This enhancement is attributed to suppression of the Kondo correlations in the "charge" circuit by the destructive quantum interference effects.

description: We find a (nonlocal) gauge where the wavefunction renormalization constant does not get any corrections for all momenta in the hard-dense loop approximation. In this gauge, we solve the Schwinger-Dyson equations for the diquark condensate in dense QCD to calculate the Cooper pair gap. We determine not only the exponent but also the prefactor of the gap in a gauge independent way. We find that the higher order corrections increase the gap only by about 1.6 times to the leading order gap at Coulomb gauge.

description: The leading corrections to electroweak precision observables in the MSSM with non-minimal flavor violation (NMFV) are calculated and the effects on M_W and sin^2 theta_eff are analyzed. The corrections are obtained by evaluating the full one-loop contributions from the third and second generation scalar quarks, including the mixing in the scalar top and charm, as well as in the scalar bottom and strange sector. Furthermore the leading corrections to the mass of the lightest MSSM Higgs boson, m_h, is obtained. The electroweak one-loop contribution to M_W can amount up to 140 MeV and up to 70x10^{-5} for sin^2 theta_eff, allowing to set limits on the NMFV parameters. The corrections for m_h are not significant for moderate generation mixing.

New infinite families of $N$th-order superintegrable systems separating in Cartesian coordinates

description: A study is presented of superintegrable quantum systems in two-dimensional Euclidean space $E_2$ allowing the separation of variables in Cartesian coordinates. In addition to the Hamiltonian $H$ and the second order integral of motion $X$, responsible for the separation of variables, they allow a third integral that is a polynomial of order $N\, (N\geq3)$ in the components $p_1, p_2$ of the linear momentum. We focus on doubly exotic potentials, i.e. potentials $V(x, y) = V_1(x) + V_2(y)$ where neither $V_1(x)$ nor $V_2(y)$ satisfy any linear ordinary differential equation. We present two new infinite families of superintegrable systems in $E_2$ with integrals of order $N$ for which $V_1(x)$ and $V_2(y)$ are given by the solution of a nonlinear ODE that passes the Painlevé test. This was verified for $3\leq N \leq 10$. We conjecture that this will hold for any doubly exotic potential and for all $N$, and that moreover the potentials will always actually have the Painlevé property.

description: This paper represents an attempt to highlight the organisational mindfulness promotion of engineering management organisations amongst their workforce. Mindfulness is an effective tool for boosting employee well-being, task performance and improving interpersonal relationships in organisations. Companies that undergo a transformation through mindfulness can observe positive returns on each segment in the organisation, making the organisation more productive, resilient and sustainable. The number of mindful organisations can be increased only if companies are willing to learn and spread the whole concept throughout every company level. For this purpose, a survey research is conducted to examine the current situation of engineering management organisations. When previous doubts are examined, while some expected doubts are confirmed, others can be considered unnecessary. Results show that although employees state their doubts and fears about organisational mindfulness programs, they are willing to attend them and believe in innovation capacity of organisational mindfulness. Furthermore, those with prior experience state the influence of organisational mindfulness can be observed in daily work routines. Thus, the research provides implications for future academic theories and professional practices.
Sticky behavior of fluid particles in the compressible Kraichnan model

description: We consider the compressible Kraichnan model of turbulent advection with small molecular diffusivity and velocity field regularized at short scales to mimic the effects of viscosity. As noted in ref.[5], removing those two regularizations in two opposite orders for intermediate values of compressibility gives Lagrangian flows with quite different properties. Removing the viscous regularization before diffusivity leads to the explosive separation of trajectories of fluid particles whereas turning the regularizations off in the opposite order results in coalescence of Lagrangian trajectories. In the present paper we re-examine the situation first addressed in ref.[6] in which the Prandtl number is varied when the regularizations are removed. We show that an appropriate fine-tuning leads to a sticky behavior of trajectories which hit each other on and off spending a positive amount of time together. We examine the effect of such a trajectory behavior on the passive transport showing that it induces anomalous scaling of the stationary 2-point structure function of an advected tracer and influences the rate of condensation of tracer energy in the zero wavenumber mode.

description: No abstracts are to be cited without prior reference to the author.In fishery it is practical impossible totally to avoid catch of fish or other organisms which cannot be sold or cannot be landed of legal reasons and therefore is unwanted in the catch (Pascoe 1997). The dominant answer to this is to discard the unwanted part of the catch. We here define discards as the proportions of both target and non-target catches discharged back overboard, either 'live' or 'dead' (Rochet and Trenkel 2005).

description: Pade approximants are used to find approximate vortex solutions of any winding number in the context of Gross-Pitaevskii equation for a uniform condensate and condensates with axisymmetric trapping potentials. Rational function and generalised rational function approximations of axisymmetric solitary waves of the Gross-Pitaevskii equation are obtained in two and three dimensions. These approximations are used to establish a new mechanism of vortex nucleation as a result of solitary wave interactions.
