description: The reproducibility crisis of modern science is the inability of scientists to reproduce roughly half of the results published in scientific journals. This crisis has affected a broad range of fields, such as psychology, chemistry, and oncology. While physicists tend to have high confidence that physics research is reproducible, no comprehensive studies have been performed to support or refute this claim. Nevertheless, the scientific, cultural, and institutional practices that contribute to the reproducibility crisis in other fields are also present in plasma science. This tutorial will describe how to implement best practices for scientific reproducibility into plasma research. The talk will begin by outlining sources of irreproducibility, such as cognitive biases, improper use of statistics, publication bias, closed access policies for data and software, and the reward system for modern academia. The talk will then describe remedies for these problems such as open access data policies; open metadata standards; open source software; training on proper use of statistics; pre-registration of research methodologies; independent methodological and statistical support; and valuing the reproducibility of research in tenure, hiring, and funding decisions.

description: Silicon dioxide and silicon (SiO$_{2}$/Si) interface plays a very important role in semiconductor industry. However, at nanoscale, its interfacial thermal properties haven't been well understood so far. In this paper, we systematically study the interfacial thermal resistance (Kapitza resistance) of a heterojunction composed of amorphous silicon dioxide and crystalline silicon by using molecular dynamics simulations. Numerical results have shown that Kapitza resistance at SiO$_{2}$/Si interface depends on the interfacial coupling strength remarkably. In the weak interfacial coupling limit, Kapitza resistance depends on both the detailed interfacial structure and the length of the heterojunction, showing large fluctuation among different samples. In contrast, it is almost insensitive to the detailed interfacial structure or the length of the heterojunction in the strong interfacial coupling limit, giving rise to a nearly constant value around 0.9 $\times10^{-9}$ m$^{2}$KW$^{-1}$ at room temperature. Moreover, the temperature dependent Kapitza resistance in the strong interfacial coupling limit has also been examined. Our study provides useful guidance to the thermal management and heat dissipation across nanoscale SiO$_{2}$/Si interface, in particular for the design of silicon nanowire based nano electronics and photonics devices.

description: Loop corrections to observables in slow-roll inflation are found to diverge no worse than powers of the log of the scale factor, extending Weinberg's theorem to quasi-single field inflation models. Demanding perturbation theory be valid during primordial inflation leads to constraints on the effective lagrangian. This leads to some interesting constraints and coincidences on the landscape of inflationary vacua.

description: We present CO (J = 1 - 0) and CO (J = 2 - 1) spectra for 19 bright, late-type galaxies (spirals) in the central region of the galaxy cluster Abell 1367 (z = 0.02) from observations made with the IRAM 30 - m telescope. All 19 spirals were observed at the position of their optical center and for a subset, at multiple positions. For each spiral the integrated CO (J = 1 - 0) intensity from the central pointing, in few cases supplemented with intensities from offset pointings, was used to estimate its molecular hydrogen mass and H_2 deficiency. Accepting the considerable uncertainties involved in determining H_2 deficiencies, spirals previously identified by us to have redder colours and higher HI deficiencies as a result of environmental influence, were found to be more H_2 deficient compared to members of the sample in less advanced evolutionary states. For eight of the observed spirals multiple pointing observations were made to investigate the distribution of their molecular gas. For these spirals we fitted Gaussians to the CO intensities projected in a line across the galaxy. In two cases, CGCG 097-079 and CGCG 097-102(N), the offset between the CO and optical intensity maxima was significantly larger than the pointing uncertainty and the FWHMs of the fits were significantly greater than those of the other spirals, irrespective of optical size. Both signatures are indicators of an abnormal molecular gas distribution. In the case of CGCG 097-079, which is considered an archetype for ram pressure stripping, our observations indicate the CO intensity maximum lies ~ 15.6 +/- 8.5 arcsec (6 kpc) NW of the optical centre at the same projected position as the HI intensity maximum.

description: We utilize a high quality calcium fluoride whispering-gallery-mode resonator to stabilize a simple erbium doped fiber ring laser with an emission frequency of 196 THz (wavelenght 1530 nm) to a linewidth below 650 Hz. This corresponds to a relative stability of 3.3 x 10^(-12) over 16 \mus. In order to characterize the linewidth we use two identical self-built lasers and a commercial laser to determine the individual lasing linewidth via the three-cornered hat method.

description: This study investigated the living conditions of the eZakheleni informal settlement, Durban metropolis of Kwazulu-Natal, South Africa. The utilized data were collected with the use of a well?structured questionnaire through a multistage sampling of 255 households. The descriptive results indicated low levels of educational attainment, large number of female headed households, high unemployment rates, inadequate sources of income, poor security and low government intervention programmes. The results of inferential analysis indicate that factors such as water accessibility, toilet accessibility, years of working experience, food security status, educational status and access to good health were the significant factors that were key to improving the living conditions of the residents in the study area. The study therefore concluded that education, basic housing services (water accessibility, toilet accessibility), food security, working experience, social connectivity and health are key contributors to households’ living condition in the study area and recommended several future research and policy directions which could improve the living conditions of the informal settlement.

description: We study the main spectral features of the gamma-ray fluxes observed by the High Energy Stereoscopic System (HESS) from the J1745-290 Galactic Center source during the years 2004, 2005 and 2006. In particular, we show that these data are well fitted as the secondary gamma-rays photons generated from dark matter annihilating into Standard Model particles in combination with a simple power law background. We present explicit analyses for annihilation in a single standard model particle-antiparticle pair. In this case, the best fits are obtained for the u and d quark-antiquark channels and for the WW and ZZ gauge bosons, with background spectral index compatible with the Fermi-Large Area Telescope (LAT) data from the same region. The fits return a heavy WIMP, with a mass above 10 TeV approximately, but well below the unitarity limit for thermal relic annihilation.

Stages of psychodynamic meaning making in the conceptualization and treatment of psychosis
Creators: name: Tan, Helen
Publisher: name: No Publisher Supplied
Year: 2022

description: Meaning-making research has recently expanded to many fields within clinical and health psychology. However, the concept of meaning making is variably defined across each field and rarely examines the psychodynamic process of symptom construction and construal in those with severe and persistent mental illness (SPMI), particularly psychosis. This paper explores the conceptualization of psychosis through a psychodynamic meaning-making perspective and proposes a related four-stage treatment model. The first stage involves the establishment of safety for the patient in and outside of treatment. Stage two focuses on the attachment processes for the patient, including exploration of experiences of disrupted attachment (if any) and the creation of a holding environment in therapy. In stage three, the patient’s previous and current belief systems are explored, carefully examined, and linked together. The fourth and final stage facilitates the integration of skills learned and used throughout treatment. At termination, the patient now possesses an understanding of the meaning-making process (i.e., how their experiences contributed to the formation of their symptoms and how these symptoms are expressions of the individual’s feelings, conflicts, fears, and wishes) and ways to manage their psychosis going forward.

description: A completely inverse $AG^{**}$-groupoid is a groupoid satisfying the identities $(xy)z=(zy)x$, $x(yz)=y(xz)$ and $xx^{-1}=x^{-1}x$, where $x^{-1}$ is a unique inverse of $x$, that is, $x=(xx^{-1})x$ and $x^{-1}=(x^{-1}x)x^{-1}$. First we study some fundamental properties of such groupoids. Then we determine certain fundamental congruences on a completely inverse $AG^{**}$-groupoid; namely: the maximum idempotent-separating congruence, the least $AG$-group congruence and the least $E$-unitary congruence. Finally, we investigate the complete lattice of congruences of a completely inverse $AG^{**}$-groupoids. In particular, we describe congruences on completely inverse $AG^{**}$-groupoids by their kernel and trace.

description: The multi-color photometric and spectroscopic observations of the newly discovered eclipsing binary T-Lyr0-08070 were obtained. The resultant light and radial velocities were analysed and the absolute parameters of the components were determined. The system is composed of an F3 and an M3 main-sequence stars. Masses and radii were estimated to be 1.37$\pm$0.23 M$_{\odot}$ and 1.60$\pm$0.09 R$_{\odot}$ for the primary and 0.32$\pm$0.04 M$_{\odot}$ and 0.86$\pm$0.06R$_{\odot}$ for the secondary star. The less massive secondary component has a radius at least two times larger with respect to its mass. Using the BVJHK magnitudes of the system we estimated an interstellar reddening of 0.22 mag and a distance to the system as 479$\pm$36 pc.

Onset of Irreversibility and Chaos in Amorphous Solids Under Periodic Shear

description: An important aspect of the physics of amorphous solids is the onset of irreversible behavior usually associated with yield. Here we study amorphous solids under periodic shear using quasi-static molecular dynamics simulations and observe a transition from reversible to irreversible deformation at a critical strain amplitude. We find that for small strain amplitudes the system exhibits a noisy but repetitive limit-cycle, similar to return point memory \cite{sethna1993hysteresis}. However, for large strain amplitudes the behavior becomes chaotic (shows sensitivity to initial conditions) and thus irreversible. We show that the chaotic behavior is a result of the shear band instabilities that arise for large strains and the convective displacement fields they create.

description: We present HST-COS spectra of ten quasars located behind M31, selected to investigate the properties of gas associated with its extended disk and high velocity clouds (HVCs). The sightlines have impact parameters ranging between b= 13 kpc and 112 kpc. No absorption is detected in the four sightlines beyond b=57 kpc. Of the six remaining sightlines, all of which lie at b<32 kpc and within the N(HI)= 2E18 cm^{-2} boundary of the HI disk of M31, we detect low-ionization absorption at M31 velocities along four of them (three of which include MgII absorption). We also detect MgII absorption from an HVC. We find that along sightlines where both are detected, the velocity location of the low-ion gas tracks the peak in 21 cm emission. High-ionization absorption is detected along the three inner sightlines, but not along the three outer sightlines, for which CIV data exist. As inferred from 21 cm emission line maps, only one sightline may have a damped Ly-alpha system. This sightline has b= 17.5 kpc, and we detect both low- and high-ion absorption lines associated with it. The impact parameters through M31 are similar to the impact parameters of galaxies identified with MgII absorbers at redshifts 0.1

description: Unsaturated swelling soil behaviour is governed by the matric suction, thus the predetermination of swelling stress for expansive unsaturated soil requires rigorous procedures. However, some swelling stress equations assume full saturation of the soil, which leads to the over-design of infrastructure. This study focused on the validation of predictive swelling stress models that correlate suction with other soil properties. Three models were developed, and independent data were used for the validation of the developed models. The predicted swelling stress values were compared to the values predicted by the randomly selected predictive models from the literature. Series of initial studies include the determination of basic soil characterization and swelling stress along with soil mineralogical compositions were conducted to determine their geotechnical properties with their corresponding degree of expansiveness. The replicated expansive soils were also studied for suction, using filter paper techniques to obtain the soil’s unsaturated parameters. Based on the obtained experimental results, three models were developed using a mathematical software package (NCSS11). Independent data obtained from a group of final year students working on the swelling stress response of expansive unsaturated soils at the geotechnical engineering Laboratory from the University of Johannesburg were used for the validation. The developed models showed good agreement with the independent data, having a coefficient 5, and 6, respectively. Compared to models selected from literature, which recorded R2 values of 0.796 and 0.636 with an average variance of 0.097 and 0.257 respectively. The correlation variables showed that the degree of expansion represented by swelling stress demonstrated a proportionality with the moisture capacity along the drying and wetting path of the suction curves. Results suggest that the developed models can reasonably predict the swelling stress of compacted expansive soils at high suction values.

description: This work introduces a time-adaptive strategy that uses a refinement estimator based on the first Frenet curvature. In dynamics, a time-adaptive strategy is a mechanism that interactively proposes changes to the time step used in iterative methods of solution. These changes aim to improve the relation between quality of response and computational cost. The method here proposed is suitable for a variety of numerical time integration problems, e.g., in the study of bodies subjected to dynamical loads. The motion equation in its space-discrete form is used as reference to derive the formulation presented in this paper. Our method is contrasted with other ones based on local error estimator and apparent frequencies. We check the performance of our proposal when employed with the central difference, the explicit generalized-alpha and the Chung-Lee integration methods. The proposed refinement estimator demands low computational resources, being easily applied to several direct integration methods.

description: The reproducibility crisis of modern science is the inability of scientists to reproduce roughly half of results published in scientific journals.  While physicists tend to have high confidence that physics research is reproducible, the scientific, cultural, and institutional practices that contribute to the reproducibility crisis in other fields are also present in plasma science.  Hypothesizing after the results are known, data dredging, and publication bias all lead to excess false positive results.  Open science practices will increase access to research, broaden research impact, and improve scientific reproducibility.  Keeping that in mind, I compare the software & data environments for solar physics and fusion energy sciences.  Open plasma science requires data that is findable, accessible, interoperable, and reusable (FAIR) as well as open source software.  I will describe community efforts like Fair4Fusion and PlasmaPy that are working to make plasma science more open.

description: Hamiltonian trajectories are strictly time-reversible. Any time series of Hamiltonian coordinates {q} satisfying Hamilton's motion equations will likewise satisfy them when played "backwards", with the corresponding momenta changing signs : {+p} --> {-p}. Here we adopt Levesque and Verlet's precisely bit-reversible motion algorithm to ensure that the trajectory reversibility is exact, with the forward and backward sets of coordinates identical. Nevertheless, the associated instantaneous Lyapunov instability, or "sensitive dependence on initial conditions" of "chaotic" (or "Lyapunov unstable") bit-reversible coordinate trajectories can still exhibit an exponentially growing time-symmetry-breaking irreversibility. Surprisingly, the positive and negative exponents, as well as the forward and backward Lyapunov spectra, are usually not closely related, and so give four differing topological measures of "local" chaos. We have demonstrated this symmetry breaking for fluid shockwaves, for free expansions, and for chaotic molecular collisions. Here we illustrate and discuss this time-symmetry breaking for three statistical-mechanical systems, [1] a minimal (but still chaotic) one-body "cell model" with a four-dimensional phase space; [2] relatively small colliding crystallites, for which the whole Lyapunov spectrum is accessible; [3] a near-continuum inelastic collision of two larger 400-particle balls. In the last two of these pedagogical problems the two colliding bodies coalesce. The particles most prone to Lyapunov instability are dramatically different in the two time directions. Thus this Lyapunov-based symmetry breaking furnishes an interesting Arrow of Time.

description: Due to the stochastic nature of environmental loadings, a lot of interest is paid in the discovery of possible damages of the involved equipment in modern industry. In wind turbine's blades, where access is difficult and expensive, the development of a smart structural health monitoring system is essential. In the present paper, a large-scale composite wind turbine blade model is designed and used for the detection of several damage scenarios. The process which is presented here is mainly based on the development of monitoring techniques which exploit the capabilities of artificial neural networks. These techniques can provide the exact position of possible damages, under given external loading scenarios. Moreover, the use of such methods decreases significantly the need of external intervention and at the same time it increases the accuracy of the whole approach. The above processes are simulated using the finite element method.

Effect of Site-disorder, Off-stoichiometry and Epitaxial Strain on the Optical Properties of Magnetoelectric Gallium Ferrite

description: We present a combined experimental-theoretical study demonstrating the role of site disorder, off-stoichiometry and strain on the optical behavior of magnetoelectric gallium ferrite. Optical properties such as band-gap, refractive indices and dielectric constants were experimentally obtained by performing ellipsometric studies over the energy range 0.8 eV to 4.2 eV on pulsed laser deposited epitaxial thin films of stoichiometric gallium ferrite with b-axis orientation and the data was compared with theoretical results. Calculations on the ground state structure show that the optical activity in GaFeO3 arises primarily from O2p-Fe3d transitions. Further, inclusion of site disorder and epitaxial strain in the ground state structure significantly improves the agreement between the theory and the room temperature experimental data substantiating the presence of site-disorder in the experimentally derived strained GaFeO3 films at room temperature. We attribute the modification of the ground state optical behavior upon inclusion of site disorder to the corresponding changes in the electronic band structure, especially in Fe3d states leading to a lowered band-gap of the material.

description: Hepatitis C virus (HCV) inhibitors are essential in the treatment of human norovirus (HuNoV). This study aimed to map out HCV NS5B RNA-dependent RNA polymerase inhibitors that could potentially be responsible for the inhibitory activity of HuNoV RdRp. It is necessary to develop robust machine learning and in silico methods to predict HuNoV RdRp compounds. In this study, Naïve Bayesian and random forest models were built to categorize norovirus RdRp inhibitors from the non-inhibitors using their molecular descriptors and PubChem fingerprints. The best model observed had accuracy, specificity, and sensitivity values of 98.40%, 97.62%, and 97.62%, respectively. Meanwhile, an external test set was used to validate model performance before applicability to the screened HCV compounds database. As a result, 775 compounds were predicted as NoV RdRp inhibitors. The pharmacokinetics calculations were used to filter out the inhibitors that lack drug-likeness properties. Molecular docking and molecular dynamics simulation investigated the inhibitors’ binding modes and residues critical for the HuNoV RdRp receptor. The most active compound, CHEMBL167790, closely binds to the binding pocket of the RdRp enzyme and depicted stable binding with RMSD 0.8–3.2 Å, and the RMSF profile peak was between 1.0–4.0 Å, and the conformational fluctuations were at 450–460 residues. Moreover, the dynamic residue cross-correlation plot also showed the pairwise correlation between the binding residues 300–510 of the HuNoV RdRp receptor and CHEMBL167790. The principal component analysis depicted the enhanced movement of protein atoms. Moreover, additional residues such as Glu510 and Asn505 interacted with CHEMBL167790 via water bridge and established H-bond interactions after the simulation. http://zinc15.docking.org/substances/ ZINC000013589565.

open source scientific software

description: The research team will lead the development of PlasmaPy and affiliated packages to foster the creation of an open source software ecosystem for plasma physics. The PlasmaPy core package will contain functionality needed by plasma physicists across disciplines, whereas affiliated packages will contain more specialized functionality. At the beginning of the project, the research team will refactor existing code, improve tests, formalize the software architecture, and improve PlasmaPy's base data structures in order to provide a solid foundation for future development. Subsequent code development priorities include a dispersion relation solver for plasma waves and instabilities, the groundwork for a flexible framework for plasma simulation, time series turbulence analysis tools, classes for the analysis of plasma diagnostics, and tools to provide access to atomic and physical data. They will make base data structures compatible with open source packages for data science to enable future data science studies. The research team will actively seek input and feedback from the plasma physics community, and adjust code development priorities based on this feedback. The team will hold workshops each year and actively support new users and contributors to grow PlasmaPy into a self-sustaining project.

title: Numerical simulation of the flow field inside a one and a half turbine stage
Creators: name: Μανος Γεωργιος
Publisher: name: Technical University of Crete
Year: 2019

description: The goal of the present thesis is to simulate a one and a half stage of a modern gas turbine, calculate performance parameters and validate said simulation through a normality check of these parameters, with the use of existing literature. The simulated one and a half turbine stage can then serve as a testbed for further investigation of turbomachinery related phenomena, such as erosion. It can also be used as a starting point in order to investigate off-design situations, such as transient phenomena, chocking, etc.
To achieve said goal, the steps taken are the following:

• Geometry measurements of existing rotor blades and stator vanes, in order to achieve adequate data for the drawing process. Other known engine parameters (for existing engine) were used to aid in the understanding of the operating conditions of the examined turbine.
• Construction of 3D drawing of the blades with the use of a CAD software.
• Meshing and simulation of the corresponding geometry with the use of an engineering simulation software.
• Calculation of dimensionless performance parameters, based on the simulation results.
• Comparison of calculated dimensionless parameters with normal ranges established in the literature.
The Shakura-Sunyaev Viscosity Prescription with Variable alpha(r)

description: Almost all hydrodynamic accretion disk models parametrize viscosity with the dimensionless parameter alpha. There is no detailed model for alpha, so it is usually taken to be a constant. However, global simulations of magnetohydrodynamic disks find that alpha varies with distance from the central object. Also, Newtonian simulations tend to find smaller alpha's than general relativistic simulations. We seek a one-dimensional model for alpha that can reproduce these two observations. We are guided by data from six general relativistic magnetohydrodynamic accretion disk simulations. The variation of alpha in the inner, laminar regions of the flow results from stretching of mean magnetic field lines by the flow. The variation of alpha in the outer, turbulent regions results from the dependence of the magnetorotational instability on the dimensionless shear rate. We give a one-dimensional prescription for alpha(r) that captures these two effects and reproduces the radial variation of alpha observed in the simulations. For thin disks, the prescription simplifies to the formula alpha(r)=0.025[q(r)/1.5]^6, where the shear parameter, q(r), is an analytical function of radius in the Kerr metric. The coefficient and exponent are inferred from our simulations and will change as better simulation data becomes available. We conclude that the alpha-viscosity prescription can be extended to the radially varying alpha's observed in simulations. It is possible that Newtonian simulations find smaller alpha's than general relativistic simulations because the shear parameter is lower in Newtonian flows.
