Clean coding

description: This presentation reviews clean coding strategies for students and scientists who have learned to program on their own without formal training. There are many pain points commonly associated with scientific software, such as lack of user-friendliness and difficult-to-read code.  Many of these pain points exist because the de facto programming paradigm in scientific research is publication-driven development (PDD), in which software is written for the purpose of publishing another research article at the expense of long-term software sustainability.  These pain points make it harder to begin research and to collaborate with other scientists, and all too often make research frustrating.  We can address many of these pain points by writing readable, reusable, and maintainable code.  Variable names should be chosen to reveal intention and meaning. The length of a variable name should be measured not by number of characters, but by the time needed to understand its meaning.  Decomposing large programs into smaller functions improves code readability, reusability, and testability.  Functions should be short and do exactly one thing with no side effects.  High-level big picture code should be separated from low-level implementation details, for example by writing code as a top-down narrative.  Because comments often become out-of-date as code evolves, it is preferable to refactor code to improve readability rather than describe how it works.  Well-written, automated tests increase the flexibility of code. Tests should be run frequently so that we can find bugs as soon as we introduce them.  In summary, we should think of code as communication.

Writing clean scientific software for plasma simulation
Creators: name: Murphy, Nicholas A.
Publisher: name: Zenodo
Year: 2019
Subjects: plasma physics, numerical simulation, scientific programming

description: Most scientific programmers are self-taught. Graduate programs in plasma physics often lack courses on scientific programming, which leaves students to learn these skills on their own. High pressure to get results prevents us from taking the time to learn practices from software engineering that can greatly improve the reliability, maintainability, and usability of software. Adopting such practices can make research more efficient and reliable, improve scientific reproducibility, and prevent future headaches. Writing readable code is particularly important because code is communication. I will discuss strategies for writing clean scientific code such as choosing meaningful variable names, refactoring code for readability in preference to commenting on how it works, and writing short functions that do exactly one thing. I will describe techniques such as periodic refactoring, continuous integration testing, test-driven development, and layering code at different levels of abstraction. I will describe how these techniques and strategies can be applied to plasma simulation software.

description: We prove the shifting theorems of the critical groups of critical points and critical orbits for the energy functionals of Finsler metrics on Hilbert manifolds of $H^1$-curves, and two splitting lemmas for the functionals on Banach manifolds of $C^1$-curves. Two results on critical groups of iterated closed geodesics are also proved; their corresponding versions on Riemannian manifolds are based on the usual splitting lemma by Gromoll and Meyer (1969). Our approach consists in deforming the square of the Finsler metric in a Lagrangian which is smooth also on the zero section and then in using the splitting lemma for nonsmooth functionals that the author recently developed in Lu (2011, 0000, 2013). The argument does not involve finite-dimensional approximations and any Palais' result in Palais (1966). As an application, we extend to Finsler manifolds a result by V. Bangert and W. Klingenberg (1983) about the existence of infinitely many, geometrically distinct, closed geodesics on a compact Riemannian manifold.

description: Time-resolved polarisation measurements of pulsars offer an unique insight into the geometry of their emission regions. Such measure\ ments provide observational constraints on the different models proposed for the pulsar emission mechanisms. Optical polarisation data of the Crab Nebula was obtained from the HST archive. The data set consists of a series of observations of the nebula taken with the HST/ACS. We produced polarisation vector maps of the inner nebula and measured, for the first time, the degree of linear polarisation (P.D.) and the position angle (P.A.) of the pulsar's integrated pulse beam, and of its nearby synchrotron knot. This yielded $\rm P.D.=5.2\pm0.3%$ and $\rm P.A.=105.1\pm1.6\degr$ for the pulsar, and $\rm P.D.=59.0\pm1.9%$ and $\rm P.A.=124.7\pm1.0\degr$ for the synchrotron knot. This is the first high-spatial resolution multi-epoch study of the polarisation of the inner nebula and pulsar. None of the main features in the nebula show evidence of significant polarisation evolution in the period covered by these observations. The results for the pulsar are consistent with those obtained by Słowikowska et al (2009) using the high-time resolution photo-polarimeter OPTIMA, once the DC component has been subtracted. Our results clearly prove that the knot is the main source of the DC component.

description: The grounded theory of Foruming was developed during a study of change within a Government Department in Australia. The aim of the study was to understand how a group of people (referred to in the thesis as the loose coalition) influenced a change process, whilst participating in it. The study is relatively unique amongst other studies of organisational change for the following reasons. The focus was on the 'loose coalition' - a group that did not solely consist of senior managers. The study developed a grounded theory to explain influence during an organisational change process. During the study, I was both a participant/researcher and a member of the loose coalition. The study was designed and conducted within the interpretive social science paradigm. Three sets of materials were collected during the study: transcripts of thirty two semi-structured interviews; stories of participating in eleven, two-day workshops; notes and recollections of my personal experience as a participant/researcher during eighteen months of the change process. The inductive analysis of materials involved moving through successive levels of conceptualisation to develop the theory of Foruming, which is: A theory of how characters create and/or attend forums with the intention of playing roles that will influence discourse, increase participation in discourse, and solicit patronage for further forums.

description: We prove that for many nonamenable groups Γ, including all hyperbolic groups and all nontrivial free products, the left-right wreath product group G := (Z/2Z)^(Γ) \rtimes (Γ\times Γ) is W*-superrigid. This means that the group von Neumann algebra LG entirely remembers G. More precisely, if LG is isomorphic with LΛfor an arbitrary countable group Λ, then Λmust be isomorphic with G.

description: Η χρήση των σύνθετων υλικών σε πολλούς κλάδους της βιομηχανίας, πρωτίστως αυτούς της αεροναυπηγικής και αεροδιαστημικής, έχει ενισχύσει και εξελίξει το ρόλο αυτού του είδους υλικών στην καθημερινότητα των ανθρώπων. Η χαμηλή αντοχή των σύνθετων πολύστρωτων υλικών σε θλιπτικές φορτίσεις , παράλληλα στην κατεύθυνση των ινών, μας οδηγεί, στην εύρεση μεθόδων ενίσχυσης της πολυμερικής μήτρας με νανοσωματίδια.
Ο στόχος  είναι η ενίσχυση του μέτρου ελαστικότητας  της μήτρας, ώστε να εμποδίζει τον λυγισμό των ινών και να αυξήσει με αυτόν τον τρόπο την αντοχή  του συνθέτου σε θλίψη. Οι μηχανικές ιδιότητες της μήτρας ενισχύονται από τα νανοσωματίδια. Μια μέθοδος ανάμειξης των νανοσωματιδίων στο πολυμερές και ταυτόχρονα προετοιμασίας της μήτρας, είναι η χρήση ενός κολλοειδούς αιωρήματος. Τα κατάλληλα προετοιμασμένα σωματίδια διασπείρονται στο εσωτερικό ενός αιωρήματος, του διαλύτη. Στη συνέχεια, υπό συνεχή ανάδευση, η ρητίνη προστίθεται στο αιώρημα, ο διαλύτης εξατμίζεται και οι πολυμερικές αλυσίδες μπορούν να διεισδύσουν μεταξύ των νανοσωματιδίων.

description: The use of composites in many sectors of the industry, primarily in those of aeronautical and aerospace, has strengthened and evolved the role of such materials in people’s everyday lives. The low strength of composite laminate materials to compressive loads, parallel to the fiber direction, leads us to find new methods of enhancing the polymeric  matrix with nanoparticles.
The mechanical properties of the matrix are supported by those of the nanoparticles, once they  ‘ve been successfully dispersed with the aid of a solvent. Then, with continuous stirring, the resin is added to the suspension, so that the polymeric chains  penetrate between the nanoparticles.
The present paper deals with the analysis of specific  experimental data such as: The fracture toughness of a composite material, which includes a matrix of epoxy resign with  carbon nanotube reinforced with carbon fibers, the strain and stress analysis, when tensile and compressive strength is present, it’s behavior to  three-point bending and it’s impact strength.
The objective is to enhance the elastic modulus of the matrix, in order to prevent buckling of the fibers and increase in this way the compressive strength of the composite.

description: The study of individual quantum systems in solids, for use as quantum bits (qubits) and probes of decoherence, requires protocols for their initialization, unitary manipulation, and readout. In many solid-state quantum systems, these operations rely on disparate techniques that can vary widely depending on the particular qubit structure. One such qubit, the nitrogen-vacancy (NV) center spin in diamond, can be initialized and read out through its special spin selective intersystem crossing, while microwave electron spin resonance (ESR) techniques provide unitary spin rotations. Instead, we demonstrate an alternative, fully optical approach to these control protocols in an NV center that does not rely on its intersystem crossing. By tuning an NV center to an excited-state spin anticrossing at cryogenic temperatures, we use coherent population trapping and stimulated Raman techniques to realize initialization, readout, and unitary manipulation of a single spin. Each of these techniques can be directly performed along any arbitrarily-chosen quantum basis, removing the need for extra control steps to map the spin to and from a preferred basis. Combining these protocols, we perform measurements of the NV center's spin coherence, a demonstration of this full optical control. Consisting solely of optical pulses, these techniques enable control within a smaller footprint and within photonic networks. Likewise, this approach obviates the need for both ESR manipulation and spin addressability through the intersystem crossing. This method could therefore be applied to a wide range of potential solid-state qubits, including those which currently lack a means to be addressed.

description: In this study, the application and evaluation of a high-order spatial and time discretization method for the numerical solution of 2-dimensional Euler equations is reported. An alternative high-order approach enhances the in-house academic solver, named EU2, employing the dimensionless Euler equations, discretized with a node-centered finite volume method on triangular unstructured girds, to simulate inviscid compressible flows. Most methodologies that have been developed during the past years, e.g. the discontinuous Galerkin and K-exact scheme, necessitate a non-trivial increase of the DoFs (Degrees of Freedom) and consequently a considerable increase of computational resources. Moreover, major modifications to existing CFD codes are required for their implementation. The adopted high-order scheme is based on the incorporation of additional high order terms to the reconstructed nodal values, used for the computation of the inviscid fluxes. The required higher-order derivatives are computed with the corresponding lower-order ones on the existing DoFs via a successive differentiation technique. As a result, the connectivity requirements are restricted to the first neighbouring points, overcoming the inherent constraint of the unstructured solvers to retrieve information from a wider computational stencil. The aforementioned technique was incorporated with a variable extrapolation numerical scheme, named U-MUSCL, which closely resembles the traditional MUSCL one, and was coupled with a high-order time discretization that employs a Strong Stability Preserving Runge-Kutta method (SSPRK). To assess the effectiveness of the aforementioned numerical scheme, the EU2 solver is used against a benchmark problem having analytic solution. A satisfactory agreement is obtained, demonstrating the proposed scheme’s potential to increase the solution’s accuracy for a given grid density. Furthermore, a corresponding high-order formulation is extended to a 3-dimensional numerical fluid model. An elaborate construction method of 3-d computational meshes for various grid types is presented in detail for future exploitation on the numerical evaluation of equivalent 3-d high-order schemes.

description: We use the two-step density-matrix renormalization group method to elucidate the long-standing issue of the universality class of the Mott transition in the Hubbard model in two dimensions. We studied a spatially anisotropic two-dimensional Hubbard model with a non-perfectly nested Fermi surface at half-filling. We find that unlike the pure one-dimensional case where there is no metallic phase, the quasi one-dimensional modeldisplays a genuine metal-insulator transition at a finite value of the interaction. The critical exponent of the correlation length is found to be $ν\approx 1.0$. This implies that the fermionic Mott transition, belongs to the universality class of the 2D Ising model. The Mott insulator is the 'ordered' phase whose order parameter is given by the density of singly occupied sites minus that of holes and doubly occupied sites.

description: We formalize the notion of monotonicity with respect to first-order stochastic dominance in the context of preferences defined over the set of temporal lotteries. It is shown that the only Kreps and Porteus (1978) preferences which are both stationary and monotone are Uzawa preferences and risk-sensitive preferences introduced by Hansen and Sargent (1995). We also extend our results to smooth recursive ambiguity models. Focusing on monotone preferences enables a much better understanding of the role of risk aversion. As an application, we derive new general results on the determinants of precautionary savings and asset prices in dynamic settings.

description: A remarkable result by S. Artstein-Avidan and V. Milman states that, up to pre-composition with affine operators, addition of affine functionals, and multiplication by positive scalars, the only fully order preserving mapping acting on the class of lower semicontinuous proper convex functions defined on $\mathbb{R}^n$ is the identity operator, and the only fully order reversing one acting on the same set is the Fenchel conjugation. Here fully order preserving (reversing) mappings are understood to be those which preserve (reverse) the pointwise order among convex functions, are invertible, and such that their inverses also preserve (reverse) such order. In this paper we establish a suitable extension of these results to order preserving and order reversing operators acting on the class of lower semicontinous proper convex functions defined on arbitrary infinite dimensional Banach spaces.

Optimising recovery in high-performance athletes through cold-water immersion
Creators: name: Rowsell, Gregory John
Publisher: name: CQUniversity
Year: 2023
Subjects: Exercise physiology

description: This thesis is based on a series of five original studies that have investigated the efficacy of using contrast showers (CS) and cold-water immersion (CWI) for enhancing recovery from intensive physical training or match play in a range of high performance athletes. Although CS and CWI are widely used by high-performance athletes, little scientific investigation has been conducted to determine whether these practices are effective for enhancing recovery and improving subsequent training or competition performance. Thus, the overall aim of this thesis was to determine the effectiveness of CS and CWI recovery strategies using 'real-life' training and competition scenarios with high ecological validity to high-performance athletes. High-performance athletes from a range of sports were studied during periods of intensive physical training or during simulated competition. Contrast showers and CWI strategies were implemented as close as possible to the end of the respective training and competition bouts and designed to replicate 'normal' practice of high performance athletes. Contrast showers involved alternating hot and cold-water exposures, and CWI, alternating bouts of cold-water immersion and seated rest. Statistical analysis was performed using repeated measures analysis of variance and magnitude based inferences (Batterham & Hopkins, 2006). A major finding from this series of studies was that a 5-min CS protocol that is recommended for use by high performance athletes does not appear to offer any ergogenic benefit for improving recovery from intensive training. Furthermore, CWI appears to offer a greater benefit for improving and maintaining performance during periods of intensive training than thermoneutral immersion (TNI). The present series of studies also suggest that CWI may reduce the perception of soreness and increase the perception of recovery in high-performance athletes from a range of sports. In conclusion, the results of the current series of studies suggest that, in preference to CS, high-performance sporting teams consider using other recovery methods that have more empirical support. Furthermore, it is recommended that, when undertaking intensive training twice a day, athletes may benefit from performing CWI between training sessions. Moreover, it is recommended that team sport athletes do not use CS and that CWI is required for effective recovery both post-match and between successive matches in a tournament. Finally, CWI should be used in preference to TNI.

description: The aim of this thesis is the improvement of the energy system of the building complex of the Orthodox Academy of Crete located in in the region of Chania. For this purpose, a model of the energy performance of the building complex is developed based on the EnergyPlus software. A simulation of the energy performance of the building complex is performed, on an annual time scale, providing the hourly energy demand for heating, cooling and electricity. Alternative energy management scenarios are then considered through the expansion of the existing 50 kWp installed photovoltaic system, combined with a water-air heat pump, and energy storage systems. Appropriate models of the alternative hybrid energy systems are developed in HOMER Energy software and annual simulations of their behaviors are carried out in order to define their optimal size. The assessment of the alternative systems is based on both economic and environmental sustainability indicators.
Perspectives from consumers with Down syndrome on their experiences at PALS programs

Publisher: name: No Publisher Supplied

description: The personal perspectives and experiences at a summer program (PALS) of individuals diagnosed with Down syndrome were surveyed with direct questions and open-ended questions. These data were collected to evaluate PALS Programs. The program runs on a one-to-one pairing model where an individual with Down syndrome and an individual without Down syndrome room together for a week in the summer. One of the goals of this research was to discover whether or not the experiences that PALS consumers have at the program reflect the five core values of PALS (Genuine, Welcoming, Fun, Passionate, and Supportive). The program was built on these values and states that every aspect of programming is created through the lens of these five characteristics. Another goal of this research was to gather additional information from the consumers’ perspectives of how acceptable and impactful the program is. The conclusions may be used to inform stakeholders of PALS Programs that their programming is doing what it intended to do for its consumers/participants. This study was a mixed method design collecting and aggregating both quantitative and qualitative data. The qualitative data, conducted through one-on-one interviews between the PI and the participants, were analyzed through the beginning stages of Strauss and Corbin’s (1990) Grounded Theory (open and axial coding) to create codes and larger themes to organize the qualitative findings. The quantitative and qualitative data provided valuable and unique evidence that PALS consumers with Down Syndrome felt that PALS was acceptable, enjoyable, and provided an impactful experience. Thematic analysis of the qualitative data reflected the five values of PALS (genuine, supportive, fun, passion and welcoming). PALS consumers with Down Syndrome revealed that their lived experiences reflected genuine, supportive, fun, passionate, and welcoming experiences. The limitations of this study consisted of a small sample size, single stakeholder data collection, and failure to include negative protocol questions. Readers should use a level of caution in the interpretation of findings. There were multiple implications from this study that should inform future research on the topic of understanding quality inclusive programming through the perspective of adults with intellectual disabilities (Down syndrome in particular).
Bethe-Heitler type radiative corrections to deeply virtual neutrinoproduction of mesons

description: We study the electromagnetic Bethe-Heitler type contribution to neutrino-induced deeply virtual meson production (\nuDVMP). Such O(α_{em})-corrections decrease with Q^{2} in the Bjorken regime less steeply than the standard \nuDVMP handbag contribution. Therefore, they are relatively enhanced at high Q^{2}. The Bethe-Heitler terms give rise to an angular correlation between the lepton and hadron scattering planes with harmonics sensitive to the real and imaginary parts of the DVMP amplitude. These corrections constitute a few percent effect in the kinematics of the forthcoming Minerva experiment at Fermilab and should be taken into account in precision tests of GPD parametrizations. For virtualities Q^{2}~100 GeV^{2} these corrections become on a par with DVMP handbag contributions. A computational code, which can be used for the evaluation of these corrections employing various GPD models is provided.
description: 15 pages, 4 Figures. We provide a code which can be used for evaluations with various GPD parametrizations (see "Ancillary files" attached to this arXiv preprint). Version 2: Minor corrections, matches published version

title: Perspektiven sozial benachteiligter Familien auf Geflüchtete und die Rolle von Medien : Befunde einer Langzeitstudie in Österreich
Creators: name: Paus-Hasebrink, Ingrid

description: Der Bericht stellt auf Basis der als qualitative Längsschnittstudie angelegten Studie „Zur Rolle  von  Medien  in  der  Sozialisation  sozial benachteiligter  Heranwachsender  (2005  bis 2017)“ Ergebnisse zur Frage vor, wie Heranwachsende in sozial benachteiligten Lebenslagen in Österreich und ihre Eltern Migranten und Migrantinnen über die gesamte Erhebungszeit sowie  insbesondere  die  Geflüchteten während  der  politisch  zugespitzten  Situation  ab  2015 wahrnahmen,  welche Einstellung  sie  ihnen gegenüber  erkennen  ließen  und welche Rolle  in diesem Zusammenhang Medien spielten. Die Ergebnisse zeigen deutlich, dass sozial schlech-ter gestellte Familien die Hilfe für Geflüchtete tendenziell als ungerecht empfinden und diese als potenzielle Konkurrenz um die Ressourcen ansehen, die sie selbst dringend bräuchten. Die Debatte um Migration und Flucht macht deutlich, dass sozial benachteiligte Familien nicht in Vergessenheit geraten dürfen und dass Medien in diesem Zusammenhang eine beachtliche Rolle zukommt und diese daher nicht aus ihrer Verantwortung gelassen werden dürfen.

description: We propose microwave-controlled rotations for qubits realized as Majorana bound states. To this end we study an inhomogeneous Kitaev chain in a microwave cavity. The chain consists of two topologically nontrivial regions separated by a topologically trivial, gapped region. The Majorana bound states at the interfaces between the left (right) regions and the central region are coupled, and their energies are split by virtual cotunneling processes. The amplitude for these cotunneling processes decreases exponentially in the number of sites of the gapped region, and the decay length diverges as the gap of the topologically trivial region closes. We demonstrate that microwave radiation can exponentially enhance the coupling between the Majorana bound states, both for classical and quantized electric fields. By solving the appropriate Liouville equation numerically we show that microwaves can drive Rabi oscillations in the Majorana sector. Our model emerges as an effective description for a topological semiconductor nanowire in a microwave cavity. Thus, our proposal provides an experimentally feasible way to obtain full single-qubit control necessary for universal quantum computation with Majorana qubits.

description: Many astronomical objects emit polarised light, which can give information both about their source mechanisms, and about (scattering) geometry in their source regions. To date (mostly) only the linearly polarised components of the emission have been observed in stellar sources. Observations have been constrained because of instrumental considerations to periods of excellent observing conditions, and to steady, slowly or periodically-varying sources. This leaves a whole range of interesting objects beyond the range of observation at present. The Galway Astronomical Stokes Polarimeter (GASP) has been developed to enable us to make observations on these very sources. GASP measures the four components of the Stokes Vector simultaneously over a broad wavelength range 400-800nm., with a time resolution of order microseconds given suitable detectors and a bright source - this is possible because the optical design contains no moving or modulating components. The initial design of GASP is presented and we include some preliminary observational results demonstrating that components of the Stokes vector can be measured to <1% in conditions of poor atmospheric stability. Issues of efficiency and stability are addressed. An analysis of suitable astronomical targets, demanding the unique properties of GASP, is also presented.

Compacting Transactional Data in Hybrid OLTP & OLAP Databases

description: Growing main memory sizes have facilitated database management systems that keep the entire database in main memory. The drastic performance improvements that came along with these in-memory systems have made it possible to reunite the two areas of online transaction processing (OLTP) and online analytical processing (OLAP): An emerging class of hybrid OLTP and OLAP database systems allows to process analytical queries directly on the transactional data. By offering arbitrarily current snapshots of the transactional data for OLAP, these systems enable real-time business intelligence. Despite memory sizes of several Terabytes in a single commodity server, RAM is still a precious resource: Since free memory can be used for intermediate results in query processing, the amount of memory determines query performance to a large extent. Consequently, we propose the compaction of memory-resident databases. Compaction consists of two tasks: First, separating the mutable working set from the immutable "frozen" data. Second, compressing the immutable data and optimizing it for efficient, memory-consumption-friendly snapshotting. Our approach reorganizes and compresses transactional data online and yet hardly affects the mission-critical OLTP throughput. This is achieved by unburdening the OLTP threads from all additional processing and performing these tasks asynchronously.

description: We discuss the problem of ultra high energy particles propagation in astrophysical backgrounds. We present two different computational schemes based on both kinetic and Monte Carlo approaches. The kinetic approach is an analytical computation scheme based on the hypothesis of continuos energy losses while the Monte Carlo scheme takes into account also the stochastic nature of particle interactions. These schemes, that give quite reliable results, enable the computation of fluxes keeping track of the different primary and secondary components, providing a fast and useful workbench to study Ultra High Energy Cosmic Rays.

description: Bordered Heegaard Floer homology is an invariant for 3-manifolds, which associates to a surface F an algebra A(Z), and to a 3-manifold Y with boundary, together with an orientation-preserving diffeomorphism ϕfrom F to \bdy Y, a module over A(Z). We study the Grothendieck group of modules over A(Z), and define an invariant lying in this group for every bordered 3-manifold. We prove that this invariant recovers the kernel of the inclusion of H_1(\bdy Y; Z) into H_1(Y; Z) if H_1(Y, \bdy Y; Z) is finite, and is 0 otherwise. We also study the properties of this invariant corresponding to gluing. As one application, we show that the pairing theorem for bordered Floer homology categorifies the classical Alexander polynomial formula for satellites.
