description: Purpose: To determine the early- and late-occurring damage in the bone marrow (BM) and peripheral blood cells of male CBA/Ca mice after exposure to 0, 0.1, 0.25, or 0.5 Gy of 1 GeV/n titanium (48Ti) ions (one type of space radiation). Method: We used the mouse in vivo blood-erythrocyte micronucleus (MN) assay for evaluating the cytogenetic effects of various doses of 1 GeV/n 48Ti ions. The MN assay was coupled with the characterization of epigenetic alterations (the levels of global 5-methylcytosine and 5-hydroxymethylcytosine) in DNA samples isolated from BM cells. These analyses were performed in samples collected at an early time-point (1 week) and a late time-point (6 months) post-irradiation. Results: Our results showed that 48Ti ions induced genomic instability in exposed mice. Significant dose-dependent loss of global 5-hydroxymethylcytosine was found but there were no changes in global 5-methylcytosine levels. Conclusion: Since persistent genomic instability and loss of global 5-hydroxymethylcytosine are linked to cancer, our findings suggest that exposure to 48Ti ions may pose health risks.

Energy-efficient and decentralized access control: a framework for embedded systems and mobility
Creators: name: Lundbæk, Leif-Nissen
Publisher: name: Imperial College London
Year: 2019

description: Based on the immanent challenges of access control in modern distributed and resource- constrained IoT networks, this thesis aims at researching and designing an energy-efficient and trustworthy framework for access control in embedded systems in a distributed setting. As such, the thesis fulfils its objectives by, first of all, developing and analysing Proof of Kernel Work (PoKW) – a novel, energy-efficient, and scalable consensus algorithm for blockchains in resource-constrained settings. It solves the issue of the rising energy consumption in the mining process of blockchains, yet, with the persistent requirement of operating in an environment with permissioned rather than permissionless/open digital identities. Thus, we also propose the expansion of PoKW towards further proof algorithms, such as PoET for finding a secure and energy-efficient consensus in open/permissionless networks. Secondly, the thesis develops FROST as a lightweight and highly flexible access-control framework and language tailored for resource-constrained settings, such as embedded devices and the infrastructure in which they are used. The FROST framework is also expanded with relevant concepts, such as obligations and the delegation of access-control policies, to particularly address the needs of reliable and secure human-machine interactions in commercial settings of the IoT and mobility space. In order to research the security and soundness of these approaches, the thesis also introduces verification mechanisms and applies them in a programmatic way using SMT solvers. Finally, the thesis also tests its theoretic contributions in two different practical settings together with Porsche or Infineon, respectively, as industry partners. This opportunity of evaluation with commercial players seems particularly important in order to identify the shortcomings as well as the vast commercial potential of the mentioned developments and concepts in the fields of IoT and especially mobility. Hereby, the thesis proves the implementability of PoKW and FROST and identifies further, potential implementation requirements, e.g., for features pertaining to obligations and delegations.

description: In den letzten Jahren rückte das Thema „Flexibles Rechnen“ zunehmend in den Fokus der mathematikdidaktischen Forschung, wobei den verschiedenen Forschungsarbeiten unterschiedliche Konzeptualisierungen zugrunde liegen (ausführlich in Rathgeb-Schnierer & Green 2013; Rathgeb- Schnierer, 2014). Konsens herrscht dahingehend, dass flexibles Rechnen als situatives, aufgabenadäquates Handeln verstanden wird, das einen beweglichen Umgang mit strategischen Werkzeugen beinhaltet. Alle Definitionen beziehen sich implizit oder explizit auf zwei Aspekte, die im Englischen mit den Begriffen „flexibility“ (den Wechsel von Lösungswerkzeugen) und „adaptivity“ (die Passung von Lösungswerkzeugen) gefasst werden. Unterschiede bestehen allerdings im Verständnis von Aufgabenadäquatheit (adaptivity) und damit verbunden in den methodischen Herangehensweisen zur Identifikation dieser (Rechtsteiner-Merz, 2013).

description: A closed expression is derived for the probability distribution of the transfer matrix of a particle moving in a one-dimensional system with delta-correlated, weak disorder. The change in the distribution as a function of wire length is described by a diffusion equation on the $SU(1,1)$ group, which is solved through the decomposition of the regular representation into irreducible components. The expression generalizes a number of well-known results, including the distributions of the transmission coefficient and local density of states. As an application, the average single energy-level contribution to the persistent current in a flux-threaded ring is derived.

description: A new computerized climate model suggests that the significant majority of children and elderly people in Qatar will be exposed to high levels of hazardous heat wave events in the next five years . Heat waves, defined as extended periods of unusually high temperatures, are well known to have adverse effects on human health and well being. These events do not just cause discomfort and inconvenience, but can exacerbate severe cardiac and respiratory diseases such as asthma. Heat waves are a major cause of fatality, and have significant negative impacts on agriculture, the economy and environment. The one that occurred in the summer of 2003, for example, is now considered to be the worst natural disaster of that year in the world. It was responsible for more than 70,000 deaths throughout Europe, and is estimated to have cost more than US$13 billion in economic loss. Summers in Qatar are prone to high temperatures, and a survey of school children there showed children had a prevalence of several respiratory diseases. This prompted Yasir Mohieldeen of the Qatar Environment and Energy Research Institute and his colleagues to launch a study of heat waves in the Gulf state. They used land surface temperature images obtained from remotely-sensed thermal data, combined with meteorological data, and integrated data about other important factors such as land use and air pollution to generate a predictive model of frequency, intensity and duration of heat waves in Qatar. The model, which is based on daily meteorological data from 2000 to 2012, suggests that at least 87% of Qatari infants under 4 years of age, as well as more than 86% of elderly people and 80% of the general population could be exposed to hazardous heat wave events at least once in the next five years. According to the model, heat waves are most likely to occur in Qatar’s northern coastal region, largely because of increased humidity and temperature as a result of air pollution from expansion of the oil and gas industries. In urban areas, such as the Qatari capital Doha, the heat waves will likely be due to increased carbon dioxide emissions from cars, the generation of electricity and heat from air conditioning units which are widespread across the country.Other InformationPublished in: QScience.com Highlights, Published by Nature Research for Hamad bin Khalifa University Press (HBKU Press)

description: Lerngelegenheiten, bzw. das englische Pendant opportunitiy to learn (OTL), sind ein zentraler Begriff in vielen Bereichen der Bildungsforschung (im Überblick: Kurz, 2011; Stevens & Grymes, 1993). Sie lassen sich definieren als „contexts in which children are asked to engage in activities that promote skill development“ (Byrnes & Wasik, 2009, S. 173). Bei der Beschreibung schulischer Lerngelegenheiten werden häufig drei Aspekte unterschieden (z. B. Leighton, Mullens, Turnbull, Weiner & Williams, 1995): Inhalte des Curriculums, Unterrichtsstrategien und Unterrichtsressourcen. Im Anschluss an Carroll (1963) lässt sich als zusätzlich relevanter Aspekt noch die Zeit ergänzen (vgl. das Modell von Kurz, 2011). Vergleicht man diese Aspekte hinsichtlich ihrer Wirkung auf die Leistungsentwicklung, so erweisen sich Inhalt und Zeit als am einflussreichsten (Elliott, 2015; Porter, 2002). Bei der Erfassung von Lerngelegenheiten haben sich – neben indirekten Maßen wie Kursniveau, Schulart u. ä. – Fragebögen als sehr geeignetes Instrument erwiesen, um die Quantität von Lerngelegenheiten zu beschreiben, weniger für deren Qualität (Porter, 2002).
Neuropsychology of Sleep and Breathing: The Effects of Obstructive Sleep Apnea Syndrome on Cognition
Creators: name: DEVITA, Maria
Publisher: name: Universit� degli Studi di Bergamo
Year: 2020

description: Obstructive Sleep Apnea Syndrome (OSAS) is a common sleep disorder that has drawn the attention of neuropsychologists because of its possible deleterious effects on cognition. Several are the causes of the impairments this syndrome can produce, like fragmentation of sleep, intermittent nocturnal hypoxia and daytime sleepiness. Apolipoprotein E4 (APOE4) may also play a role in OSAS and it has been suggested as a trigger of cognitive impairment and of dementia-like patterns. This dissertation begins with a critical review of the literature, with the aim to provide the current overview of the main controversies about OSAS and its effects on brain and cognition. Three experimental studies aiming to shed light on the nature of the relationship between OSAS and cognition are then proposed. The first two studies focus on the effects of OSAS on information processing speed. Innovative measures have been proposed to clarify whether different components of information processing speed are impaired in OSAS (Study 1), and to evaluate the efficacy over time of the continuous positive airway pressure treatment (Study 2). Finally, Study 3 aims to evaluate the effects of APOE4 on psychometric performance, and to investigate at which sleep stage its presence could be a predictor of cognitive impairments in OSAS patients. Results show that OSAS is associated with impairment of the motor component of information processing speed, which can however be properly recovered after treatment. Furthermore, a retention memory deficit is reported in OSAS patients carrying APOE4, and NREM sleep fragmentation has been found to be directly involved in this impairment. This dissertation supports the hypothesis of a cognitive frailty associated with OSAS, however discouraging its irreversibility, and argues that APOE4 can be considered a risk factor for the memory loss observed in this syndrome.

description: The Lustre file system has become a preferred storage resource for systems on the Top500 list, and it is often the file system of choice for small- to medium-sized HPC systems that require parallel shared access to data. Several resources exist to help users deploy and configure Lustre, but the same cannot be said for resources that explain the inner workings of the Lustre source code. A previous ORNL technical report entitled "Understanding Lustre Filesystem Internals" (ORNL/TM-2009/117) provided an excellent summary of Lustre subsystem operations. However, that report is over a decade old and is based on Lustre version 1.6. Since that report was published, Lustre has evolved significantly. Several subsystems underwent significant code changes and many new features have been added to the file system, bringing the current Lustre version up to 2.15. In this presentation we describe the efforts taken to develop a comprehensive documentation of internal mechanics of the latest version of Lustre file system. The documentation is hosted in the main community repository for Lustre, wiki.lustre.org under the title "Understanding Lustre Internals". Pivotal sections and subtopics in the documentation are Lustre architecture featuring its core components, software stack and file layouts, Lustre test suite, user utilities and core subsystems including MGC, Obdclass, Libcfs and File identifiers. In this talk, we first outline the limitations of the existing resources, then the methodology followed to focus on writing key data structures and APIs, and lastly exhibit the new documentation page hosted in wiki.lustre.org. Through this talk, we seek to encourage contributions from the Lustre community to extend the documentation further with relevant contents and keep it up to date with Lustre source code changes.
Exploring the behaviour of two-dimensional dry polar active fluids in a dense regime
Creators: name: Nesbitt, David Michael
Publisher: name: Imperial College London
Year: 2019

description: Active matter is the study of many-body systems driven out of equilibrium at a local level. Typical examples are found in biology and span many length scales, such as flocks of birds or tissues of cells. This thesis focuses on non-momentum conserving (dry), polar systems, whose hydrodynamics are generically described by the Toner-Tu equations. These systems exhibit a variety of emergent behaviour, such as collective motion and phase separation, which often only emerge at high densities. By adapting the standard lattice Boltzmann method for fluid mechanics, we develop a new method for simulating dry, polar active fluids. In particular this method is easy to implement and effective at high densities. Through a Chapman-Enskog style expansion, we confirm that the corresponding macroscopic equations are the Toner-Tu equations, and connect the system parameters with the coefficients of the equations. We demonstrate the functionality and adaptability of our method by recreating two different phenomena: motility-induced phase separation and collective motion. Furthermore, by incorporating contact inhibition of locomotion effects into the collective motion model, we uncover two new first order phase transitions and a potentially new critical transition. We interpret these transitions through a stability analysis. In addition, we perform a stability analysis on an open interface of a fluid that obeys an incompressible version of the Toner-Tu equations. We find that collective motion stabilises the interface, but the interface is unstable when starting from a stationary state. This has implications for both wound healing and the results of our simulations.

description: As an emerging research direction, online streaming feature selection deals with sequentially added dimensions in a feature space while the number of data instances is fixed. Online streaming feature selection provides a new, complementary algorithmic methodology to enrich online feature selection, especially targets to high dimensionality in big data analytics. This paper introduces the first comprehensive open-source library for use in MATLAB that implements the state-of-the-art algorithms of online streaming feature selection. The library is designed to facilitate the development of new algorithms in this exciting research direction and make comparisons between the new methods and existing ones available.
Reservoir modeling and inversion using generative adversarial network priors
Creators: name: Mosser, Lukas J.
Publisher: name: Imperial College London
Year: 2019

description: Determining the spatial distribution of geological heterogeneities and their petrophysical properties is key to successful hydrocarbon production and carbon capture and storage. Due to the sparse nature of direct observations of the earth’s interior from borehole data, most inferences about the interior structure of the earth and its properties have to be made by indirect observation such as seismic reflection or dynamic data. Determining these property distributions from indirect observations requires solving an ill-posed inverse problem which can be defined as a Bayesian inference problem where we seek to obtain the posterior distribution of the subsurface properties given the observed data. Recently, deep generative modeling has enabled multi-modal probability distributions of large three-dimensional natural images to be represented. Generative Adversarial Networks (GANs) are deep generative models that learn a representation of the probability distribution implicitly defined by a set of training images using two competing neural networks. This thesis introduces GANs as probabilistic models of geological features and petrophysical properties at the reservoir scale and images of porous media at the pore-scale. A GAN can be trained to represent pore-scale micro-CT images of segmented and grayscale porous media. After training, the GAN generator is used to sample large high-fidelity realizations that follow the same statistical and physical properties as represented in the training images. Using GANs as a probabilistic generative model allows them to be incorporated in a Bayesian inversion workflow. Based on a synthetic test-case, two inverse problems were considered: inversion of acoustic properties from seismic observations and reservoir history matching of a two-phase flow problem at the reservoir-scale. In both cases, the posterior distribution of the petrophysical property distributions was obtained using approximate Bayesian inference over the latent variables. The samples obtained from the posterior match the observed seismic or production data, and can be conditioned to direct observations at wells. This approach of deep stochastic inversion based on deep generative models such as GANs opens new opportunities for geological modeling and solving ill-posed inverse problems.

description: The conjugacy problem for a finitely generated group $G$ is the two-variable problem of deciding for an arbitrary pair $(u,v)$ of elements of $G$, whether or not $u$ is conjugate to $v$ in $G$. We construct examples of finitely generated, computably presented groups such that for every element $u_0$ of $G$, the problem of deciding if an arbitrary element is conjugate to $u_0$ is decidable in quadratic time but the worst-case complexity of the global conjugacy problem is arbitrary: it can be any c.e. Turing degree , can exactly mirror the Time Hierarchy Theorem, or can be $\mathcal{NP}$-complete. Our groups also have the property that the conjugacy problem is generically linear time: that is, there is a linear time partial algorithm for the conjugacy problem whose domain has density $1$, so hard instances are very rare. We also consider the complexity relationship of the "half-conjugacy" problem to the conjugacy problem. In the last section we discuss the extreme opposite situation: groups with algorithmically finite conjugation.

description: The immediate impact of child maltreatment on health and developmental trajectories over time is unknown. Longitudinal studies starting in the direct aftermath of exposure with repeated follow‐up are needed. Method We assessed health and developmental outcomes in 6‐month intervals over 2 years in 173 children, aged 3–5 years at study entry, including 86 children with exposure to emotional and physical abuse or neglect within 6 months and 87 nonmaltreated children. Assessments included clinician‐administered, self‐ and parent‐report measures of psychiatric and behavioral symptoms, development, and physical health. Linear mixed models and latent growth curve analyses were used to contrast trajectories between groups and to investigate the impact of maltreatment features on trajectories. Results Maltreated children exhibited greater numbers of psychiatric diagnoses (b = 1.998, p < .001), externalizing (b = 13.29, p < .001) and internalizing (b = 11.70, p < .001) symptoms, impairments in cognitive (b = −11.586, p < .001), verbal (b = −10.687, p < .001), and motor development (b = −7.904, p = .006), and greater numbers of medical symptoms (b = 1.021, p < .001) compared to nonmaltreated children across all time‐points. Lifetime maltreatment severity and/or age at earliest maltreatment exposure predicted adverse outcomes over time. Conclusion The profound, immediate, and stable impact of maltreatment on health and developmental trajectories supports a biological embedding model and provides foundation to scrutinize the precise underlying mechanisms. Such knowledge will enable the development of early risk markers and mechanism‐driven interventions that mitigate adverse trajectories in maltreated children.
Geological constraints on surface-based models through development of Rapid Reservoir Modelling
Creators: name: Pataki, Margaret Elizabeth Hoyt
Publisher: name: Imperial College London
Year: 2019

description: Surface-based geological modelling (SBM) represents all geological heterogeneity that impacts the spatial distribution of petrophysical properties using surfaces. To create surface-based models, rules are required to govern how surfaces interact such that resulting models are geologically sound. Previous studies used implicit rules or assumptions, often with the requirement that surfaces are created in stratigraphic or hierarchical order. A comprehensive set of explicit and universal rules to govern the interaction of stratigraphic surfaces has yet to be formalised. In this thesis, seven operators are presented that define how stratigraphic surfaces interact for geological modelling such that universal geological rules are obeyed. The operators can be applied through any SBM technique and are independent of geological process, scale and setting. The operators are demonstrated using three hand-drafted examples of siliciclastic and carbonate strata, at centimetre to kilometre scales, using outcrop, seismic and conceptual input data. These universal stratigraphic operators are then implemented in 3D in the sketch-based interface and modelling (SBIM) research prototype software Rapid Reservoir Modelling (RRM). Three case studies are presented using examples of siliciclastic and carbonate strata from different depositional environments, at multiple scales, using seismic, outcrop, and well log data to constrain and guide the sketches. The case studies demonstrate the operators and three different techniques for moving from 2D sketch to 3D model, revealing the flexibility and broad applicability of the operators for SBIM of stratigraphy. Lastly, the stratigraphic operators are leveraged in RRM to create structural models. Test cases are a conjugate fault model and a physical model of a salt-influenced passive margin. Gaps in the applicability of stratigraphic operators for ‘sketch-what-you-see’ structural modelling and diagenesis are identified and future updates to RRM are recommended. RRM is the first SBIM software that allows rapid prototyping of geological reservoir models and represents a step-change for the field.

description: In micro-blogging platforms, people connect and interact with others. However, due to cognitive biases, they tend to interact with like-minded people and read agreeable information only. Many efforts to make people connect with those who think differently have not worked well. In this paper, we hypothesize, first, that previous approaches have not worked because they have been direct -- they have tried to explicitly connect people with those having opposing views on sensitive issues. Second, that neither recommendation or presentation of information by themselves are enough to encourage behavioral change. We propose a platform that mixes a recommender algorithm and a visualization-based user interface to explore recommendations. It recommends politically diverse profiles in terms of distance of latent topics, and displays those recommendations in a visual representation of each user's personal content. We performed an "in the wild" evaluation of this platform, and found that people explored more recommendations when using a biased algorithm instead of ours. In line with our hypothesis, we also found that the mixture of our recommender algorithm and our user interface, allowed politically interested users to exhibit an unbiased exploration of the recommended profiles. Finally, our results contribute insights in two aspects: first, which individual differences are important when designing platforms aimed at behavioral change; and second, which algorithms and user interfaces should be mixed to help users avoid cognitive mechanisms that lead to biased behavior.

What embedded counterfactuals tell us about the semantics of attitudes

description: We discuss German examples where counterfactuals restricting an epistemic modal are embedded under glauben ‘believe’. Such sentences raise a puzzle for the analysis of counterfactuals, modals, and belief attributions within possible-worlds semantics. Their truth conditions suggest that the modal’s domain is determined exclusively by the subject’s belief state, but evaluating the counterfactual separately at each of the subject’s doxastic alternatives does not yield the correct quantificational domain: the domain ends up being determined by the facts of each particular world, which include propositions the subject does not believe. We therefore revise the semantics of counterfactuals: counterfactuals still rely on an ordering among worlds that can be derived from a premise set (Kratzer, Angelika. 1978. Semantik der Rede: Kontexttheorie – Modalwörter – Konditionalsätze (Monographien Linguistik und Kommunikationswissenschaft 38). Königstein: Scriptor, 2012 [1981]a. The notional category of modality. In Modals and conditionals (Oxford studies in theoretical linguistics 36), 27–69. Oxford: Oxford University Press), but rather than uniquely characterizing a world, this premise set can be compatible with multiple worlds. In belief contexts, the attitude subject’s belief state as a whole determines the relevant ordering. This, in turn, motivates a revision of the semantics of believe: following Yalcin’s work on epistemic modals (Yalcin, Seth. 2007. Epistemic modals. Mind 116. 983–1026), we submit that evaluation indices are complex, consisting of a world and an ordering among worlds. Counterfactuals are sensitive to the ordering component of an index. Attitude verbs shift both components, relativizing the ordering to the attitude subject.

description: Team collaboration plays a key role in the success of any multi-user activity. Software engineering is a highly collaborative activity, where multiple developers and designers work together to solve a common problem. Meaningful and effective designer-developer collaboration improves the user experience, which can improve the chances of success for the project. Learning to program is another activity that can be implemented in a more collaborative way, students can learn in an active style by working with others. The growth of online classes, from small structured seminars to massive open online courses (MOOCs), and the isolation and impoverished learning experience some students report in these, points to an urgent need for tools that support remote pair programming in a distributed educational setting. In this paper, we describe Jimbo, a collaborative integrated development environment (IDE) that we believe is beneficial and effective in both aforementioned activities. Jimbo integrates many features that support better collaboration and communication between designers and developers, to bridge communication gaps and develop mutual understanding. These novel features can improve today's CS education by bringing students closer to each other and their instructors as well as training them to collaborate which is consistent with current practices in software engineering.

Tuning the graphene band gap by thermodynamic control of molecular self-assembly on graphene
Creators: name: Hildebrand, Mariana

description: Recent interest in functionalised graphene has been motivated by the prospect of creating a two-dimensional semiconductor with a tuneable band gap. Various approaches to band gap engineering have been made over the last decade, one of which is chemical functionalisation. However, the patterning of molecular adsorption onto graphene has proved to be difficult, as grown structures tend to be stochastic in nature. In the first part of this work, a predictive physical model of the self-assembly of halogenated carbene layers on graphene is suggested. Self-assembly of the adsorbed layer is found to be governed by a combination of the curvature of the graphene sheet, local distortions, as introduced by molecular adsorption, and short-range intermolecular repulsion. The thermodynamics of bidental covalent molecular adsorption and the resultant electronic structure are computed using Density Functional Theory. It is predicted that a direct band gap is opened that is tuneable by varying coverages and is dependent on the ripple ampli- tude. This provides a mechanism for the controlled engineering of graphene’s electronic structure and thus its use in semiconductor technologies. In the second part of this work, the formation of intrinsic ripples in graphene sheets under isotropic compression is examined. An isotropic compression of graphene is shown to induce a structural deformation on the basis of Density Functional Perturbation Theory. Static instabilities, indicated by imaginary fre- quency phonon modes, are induced in the high symmetry Γ – K (zigzag) and Γ – M (armchair) directions by an isotropic compressive strain of the graphene sheet. The wavelength of the unstable modes (ripples) is directly related to the magnitude of the strain and remarkably insensitive to the direction of propagation in the 2D lattice. These calculations further suggest that the formation energy of the ripple is isotropic for lower strains and becomes anisotropic for larger strains. This is a result of graphene’s elastic property, which is depen- dent on direction and strain. Within the quasi harmonic approximation this is combined with the observation that molecular adsorption energies depend strongly on curvature to suggest a strategy for generating ordered overlayers in order to tune the functional properties of graphene. Based on the results of this work, we can conclude that (pre-)rippled graphene sheets can be used to direct molecular adsorption in order to form specific patterns by tuning the thermodynamic equilibrium of the addition reaction of small (organic) molecules.

description: The snowbed habitats represent a relevant component of the alpine tundra biome, developing in areas characterized by a long-lasting snow cover. Such areas are particularly sensitive to climate changes, because small variations in air temperature, rain, and snowfall may considerably affect the pedoclimate and plant phenology, which control the soil C and N cycling. Therefore, it is fundamental to identify the most sensitive abiotic and biotic variables affecting soil nutrient cycling. This work was performed at seven permanent snowbed sites belonging to Salicetum herbaceae vegetation community in the northwestern Italian Alps, at elevations between 2,686 and 2,840 m.a.s.l. During a four-year study, we investigated climate, pedoclimate, floristic composition, phenology, and soil C and N dynamics. We found that lower soil water content and earlier melt-out day decreased soil N-NH4+, N-NO3−, dissolved organic carbon (DOC), dissolved organic nitrogen (DON), total dissolved nitrogen (TDN), microbial nitrogen (Nmicr), microbial carbon (Cmicr), and C:Nmicr ratio. The progression of the phenological stages of Salix herbacea reduced soil N-NH4+ and increased DOC. Our results showed that the snow melt-out day, soil temperature, soil water content, and plant phenological stages were the most important factors affecting soil biogeochemical cycles, and they should be taken into account when assessing the effects of climate change in alpine tundra ecosystems, in the framework of long-term ecological research.

description: Linear stability analysis has proven to be a useful tool in the analysis of dominant coherent structures, such as the von Kármán vortex street and the global spiral mode associated with the vortex breakdown of swirling jets. In recent years, linear stability analysis has been applied successfully to turbulent time-mean flows, instead of laminar base-flows, \textcolor{black}{which requires turbulent models that account for the interaction of the turbulent field with the coherent structures. To retain the stability equations of laminar flows, the Boussinesq approximation with a spatially nonuniform but isotropic eddy viscosity is typically employed. In this work we assess the applicability of this concept to turbulent strongly swirling jets, a class of flows that is particularly unsuited for isotropic eddy viscosity models. Indeed we find that unsteady RANS simulations only match with experiments with a Reynolds stress model that accounts for an anisotropic eddy viscosity. However, linear stability analysis of the mean flow is shown to accurately predict the global mode growth rate and frequency if the employed isotropic eddy viscosity represents a least-squares approximation of the anisotropic eddy viscosity. Viscosities derived from the $k-ε$ model did not achieve a good prediction of the mean flow nor did they allow for accurate stability calculations. We conclude from this study that linear stability analysis can be accurate for flows with strongly anisotropic turbulent viscosity and the capability of the Boussinesq approximation in terms of URANS-based mean flow prediction is not a prerequisite.
