Probing the Protostellar Envelope around L1157: the Dust and Gas Connection

description: We present observations of the Class 0 protostar L1157-mm using the Combined Array for Research in Millimeter-wave Astronomy (CARMA) in 3 mm dust continuum and N2H+ line emission. In the N2H+ line, we detect a large-scale envelope extended over a linear size of ~20,000AU flattened in the direction perpendicular to the outflow. This N2H+ feature coincides with the outer envelope seen in the 8 micron extinction by Looney et al. Meanwhile, the dust continuum traces the compact, nearly spherical structure of the inner envelope, where N2H+ becomes depleted. This highly flattened N2H+ envelope also shows dynamical signatures consistent with gravitational infall in the inner region, but a slow, solid-body rotation at large scales. This flattened structure is not a rotationally supported circumstellar disk; instead, it resembles a prestellar core both morphologically and kinematically, representing the early phase of a Class 0 system. In this paper, we construct a simple model to interpret both the dust continuum and N2H+ emission and suggest a possible dynamical scenario for the overall properties of the envelope.

description: Topological Josephson junctions (TJJs) have been a subject of widespread interest due to their hosting of Majorana zero modes. In long junctions, i.e. junctions where the junction length exceeds the superconducting coherence length, TJJs manifest themselves in specific features of the critical current. Here we propose to couple the helical edge states mediating the TJJ to additional channels or quantum dots, by which the effective junction length can be increased by tunable parameters associated with these couplings, so that such measurements become possible even in short junctions. Besides effective low-energy models that we treat analytically, we investigate realizations by a Kane-Mele model with edge passivation and treat them numerically via tight binding models. In each case, we explicitly calculate the critical current using the Andreev bound state spectrum and show that it differs in effective long junctions in the cases of strong and weak parity changing perturbations (quasiparticle poisoning).

description: The Majorana resonant level model (MRLM) describes the universality class of the two-channel/terminal Kondo model at the Toulouse point as well as of a resonant level between two half-infinite Tomonaga--Luttinger liquids. We analyze the time evolution of the electric current and of the population function after an instantaneous switching on of the tunneling coupling. We find that the only timescale, which governs the relaxation of the initial dot preparation is the inverse contact transparency $Γ$, whatever the dot offset energy $Δ$, applied bias voltage or temperature. The voltage alone determines the superimposed oscillatory behavior of the observables for weak detuning $|Δ|Γ/2$ a beating pattern emerges. For the current the finite temperature plays the similar role as the hybridization. The dot population function dynamics approaches that of a resonant ($Δ=0$) setup upon increasing the voltage or/and temperature.
title: How can we make better use of crop residues?
Creators: name: Struijk, Marijke
Publisher: name: University of Reading
Year: 2020

description: Crop residues are a widely available on-farm resource that contain calories, carbon and other nutrients. However, decomposition of crop residue soil amendments does not always translate into greater SOM levels, increased nutrient availability, or improved soil structure. Therefore, a better understanding of the decomposition processes involved is needed to improve the management of crop residues in arable and horticultural cropping systems. In this thesis, an extensive literature review and an investigation of the link between aboveground crop diversity and belowground soil biota suggested two strategies to increase SOM accumulation with crop residue amendments. The potential of these strategies was assessed in two experiments underpinned by ecological theories that have previously been observed in natural systems: (1) a test of the applicability of the home-field advantage (HFA) hypothesis (i.e. litter decomposes faster in soil in which it was grown, home, compared to a different soil, away) to arable cropping systems; and (2) a trial to exploit litter-mixing effects observed in forest ecosystems, in which crop residues of different chemical qualities were applied as mixtures and as individual residues to a horticultural soil. Different abundances of soil fauna were observed at the different stages of an arable crop rotation. However, no HFA effect could be detected within this same crop rotation. Soil amendment with mixtures of chemically contrasting crop residues, on the other hand, led to non-additively greater SOM and available N levels within a short time frame (44 days). Crop-residue mixing may therefore be a more suitable strategy to make better use of crop residues in arable and horticultural systems. This strategy may have practical implications, because it would involve the removal, mixing and re-application of crop residues, rather than simply returning them to the soils they were grown in. There is a need for a more mechanistic understanding of HFA effects, which may help explain why no HFA effect was found in this research project. Therefore, I envision a future HFA microcosm experiment in which possible factors that drive HFAs are controlled.

Properties of starspots on CoRoT-2

description: As a planet eclipses its parent star, a dark spot on the surface of the star may be occulted, causing a detectable variation in the light curve. A total of 77 consecutive transit light curves of CoRoT-2 were observed with a high temporal resolution of 32 s, corresponding to an uninterrupted period of 134 days. By analyzing small intensity variations in the transit light curves, it was possible to detect and characterize spots at fixed positions (latitude and longitude) on the surface of the star. The model used simulates planetary transits and enables the inclusion of spots on the stellar surface with different sizes, intensities (i.e. temperatures), and positions. Fitting the data by this model, it is possible to infer the spots physical characteristics. The fits were either in spot longitude and radius, with a fixed intensity, or in spots longitude and intensity, for spots of constant size. Before the modeling of the spots were performed, the planetary radius relative to the star radius was estimated by fitting the deepest transit to minimize the effect of spots. A slightly larger (3%) radius, 0.172 Rstar, resulted instead of the previously reported 0.1667 Rstar . The fitting of the transits yield spots, or spot groups, with sizes of ranging from 0.2 to 0.7 planet radius, Rp, with a mean of (0.41 +/- 0.13) Rp (~100,000 km), resulting in a stellar area covered by spots within the transit latitudes of 10-20%. The intensity varied from 0.4 to 0.9 of the disk center intensity, Ic, with a mean of (0.60 +/- 0.19) Ic, which can be converted to temperature by assuming an effective temperature of 5625 K for the stellar photosphere, the spots temperature ranges mainly from 3600 to 5000 K. The results from the spot modeling are in agreement with those found for magnetic activity analysis from out of transit data of the same star.

description: Atomic spin polarization of alkali atoms in the ground state can survive thousands of collisions with paraffin-coated cell walls. The resulting long spin-relaxation times achieved in evacuated, paraffin-coated cells enable precise measurement of atomic spin precession and energy shifts of ground-state Zeeman sublevels. In the present work, nonlinear magneto-optical rotation with frequency-modulated light (FM NMOR) is used to measure magnetic-field-induced spin precession for rubidium atoms contained in a paraffin-coated cell. The magnetometric sensitivity of FM NMOR for the rubidium D2 line is studied as a function of light power, detuning, frequency-modulation amplitude, and rubidium vapor density. For a 5-cm diameter cell at temperature T ~ 35 degrees C, the optimal shot-noise-projected magnetometric sensitivity is found to be 2 x 10^{-11} G/Hz^{1/2} (corresponding to a sensitivity to spin precession frequency of ~ 10 microHz/Hz^{1/2} or a sensitivity to Zeeman sublevel shifts of ~ 4 x 10^{-20} eV/Hz^{1/2}).

title: Selection of lactic acid bacteria for use as starter cultures in Lafun production and their impact on product quality and safety

description: Lafun is one of the fermented cassava products of West Africa. However, current production systems, which use spontaneous fermentation, result in variable product quality and reduced safety. Therefore, there is an interest in developing a manufacturing process to overcome these challenges. An important element that could resolve the above issues is the use of starter cultures. Therefore, this thesis focuses on the selection of lactic acid bacteria (LAB) from fermenting cassava that have potential use as starter cultures for lafun production and explores their impact on final product quality and safety. Lactic acid bacteria isolates (n=41) from spontaneous fermentation of cassava were characterised and screened for flavour compounds production. Four strains were identified as having the greatest potential use as starter cultures (n=4) and were genotypically identified as Weissella koreensis (2 strains), Lactococcus lactis and Leuconostoc mesenteroides. These four strains were further screened for antibiotic resistant genes and did not seem to contain any such genes. Following starter culture addition, subsequent processing operations may impact on lafun flavour. Therefore, fermentation time and drying of lafun were investigated to enhance the laboratory production of lafun. Acidification rate of the selected isolates was also assessed to also identify possible starter culture combinations where one strain is a strong acidifier while the other enhances flavour. The impact of the developed starters, singly and in combination, on lafun nutritional quality, rheological properties, volatile flavour profile, NMR metabolite profile, cyanide reduction and microbial load was evaluated. Three cassava varieties (Bitter: IBA30527; Fortified: IBA011371; and Sweet: TMEB117) were fermented, in duplicate, to produce samples for analyses. Fermentation for 48 h without pressing the fermented cassava roots favoured the yield of desirable flavour compounds. The results support the adoption of fortified cassava for lafun production due to its positive flavour, nutritional and physical properties.

description: We say that the polynomial sequence $(Q^{(λ)}_n)$ is a semiclassical Sobolev polynomial sequence when it is orthogonal with respect to the inner product $$ _S= +λ, $$ where ${\bf u}$ is a semiclassical linear functional, ${\mathscr D}$ is the differential, the difference or the $q$--difference operator, and $λ$ is a positive constant. In this paper we get algebraic and differential/difference properties for such polynomials as well as algebraic relations between them and the polynomial sequence orthogonal with respect to the semiclassical functional $\bf u$. The main goal of this article is to give a general approach to the study of the polynomials orthogonal with respect to the above nonstandard inner product regardless of the type of operator ${\mathscr D}$ considered. Finally, we illustrate our results by applying them to some known families of Sobolev orthogonal polynomials as well as to some new ones introduced in this paper for the first time.

title: The acute effects of Vitamin D (25-dihydroxyvitamin D3) on cognition in healthy young and middle aged adults
Creators: name: Che Taha, Che Suhaili Binti

description: Vitamin D was established for its skeletal function with less evidence available for its non-skeletal function, including cognitive function. Following recent interest in vitamin D supplementation to improve cognitive function perfonnance, this thesis aimed to identify the acute effects of 25-dihydroxyvitamin D3 on 25(OH)D levels and cognitive function, as well as other health outcomes such as mood and sleep. Two intervention studies; acute, randomized, double-blind, crossover intervention studies were conducted with the first study comparing the acute effect of 25- dihydroxyvitamin D3 and the usual form of vitamin D3 on plasma vitamin D levels and cognitive function at 8 and 24 hours post intervention. Results revealed that 25- dihydroxyvitamin D3 increased plasma vitamin D levels but not cognitive perfonnance relative to the Vitamin D3 formed at 24 hours, thus the second experiment was conducted to explore dose response effects on cognitive performance, as well as mood and sleep. Four doses of 0, 800, 2,000 and 4,000 IU of 25- dihydroxyvitamin D3 were used in this study. It was found that a low dose of 800 IU of 25-dihydroxyvitamin D3 revealed better perfonnance on executive function compared to higher doses of 2,000 and 4,000 IU. Conversely, quicker processing speed was observed after placebo and 2,000 IU. These findings suggested 25- dihydroxyvitamin D3 is most likely to benefit cognitive function at a low dose but not at a high dose. Finally, considering that the majority of vitamin Dis produced by skin exposure to the sun, this thesis also explored seasonal vitamin D levels and the effects on cognition and mood. It is evident that vitamin D level was significantly higher during summer with a higher score indicating more times was spent outside. This exploratory study also showed that participants completed the Stroop Task quicker with less errors during summer which suggested the positive effect of being outdoor under the sunshine. Overall, whilst evidence for acute effects of Vitamin D on cognition in the current thesis was mixed, future studies are recommended to includ
title: Dialogues in cybernetics: a model for understanding critical thinking construction in the digital age
Creators: name: Cavalcanti das Neves Valle, Lucia Helena

Year: 2021

description: This thesis study examines the Critical Thinking construction from students while using the digital technologies for web-based activities at school. At the end, we propose a model that explains Critical Thinking based on the Science of Cybernetics. Critical learning opportunities within schools are needed urgently. Critical thinkers will be adaptable to technologies and therefore will present essential qualities for the Digital Age. The scientific literature is full of arguments to support this approach, however, apart from some studies that propose a linear model for this matter, not much has been proposed concerning a complex model for Critical Thinking in the Digital Age. To this end, the research question is as follows: How is the critical thinking process fostered at the Cognition Level in the Digital Age? This is addressed by considering the process of critical thinking as an open system, according to principles of Cybernetics. Data for the study was collected twice. The initial Pilot Study revealed unexpected phenomena which current theories in Education could not explain. In the Main Study, a Cybernetic approach was used preserving identical research techniques and data analysis instruments from the initial study. Both studies used a Research Protocol Activity executed by participants and, after that, a clinical interview. Data were analysed and a Cybernetic Model for Critical Thinking proposed, applying the principles of Entropy and of Selective Retention, to explain how critical thinking is built in the Cognitive level. The Model has been built from the exploratory Pilot Study and the Main Theoretical Study. This thesis presents the background of Critical Thinking, with a theory and concepts that will help to stimulate critical thoughts, suggesting the path that must be taken to stimulate and develop critical thinking in students. This work has a significant contribution to the existing critical thinking literature, proposing a holistic approach that includes Cybernetics and Cognition. The developed concepts of �Entropy�, �Deterrence�, and the Model itself can help assessing learning and cognition in another dimension. We proposed the concept of Entropy to critical thinking (see Chapter 5) fostered from a large literature review that involved Philosophy, Sociology, Education and Cybernetics. The concept will be helpful to researchers who want to dedicate their project to cognitive phenomena, or to Human-machine interaction. Similarly, the concept of Deterrence can equally be used for areas where cognition, education society and Cybernetics can be helpful. However, further work is needed to extend this study for other populations, such as adults and university undergraduates. By validating the model in such populations, it could be successfully applied to foster critical thinking in most human beings, while involving digital technologies.

Optogenetic tools for corticospinal tract modulation

description: Among the pathways susceptible to damage following spinal cord injury (SCI) is the corticospinal tract (CST), a supraspinal projection responsible for voluntary control of the distal limbs. Previous work has shown that enhancing cortical CST activity via neuromodulation promotes plasticity and improves motor function following SCI. However, conventional stimulation modalities either lack cell-type specificity, or do not afford temporal control of neuronal firing. The technique of optogenetics addresses these shortcomings by genetically modifying a targeted subset of neurons to express light-gated ion channels, called opsins, which enable the millisecond-scale control of neuronal firing following light exposure. Few barriers currently exist which limit the ability to study the potential plasticity-inducing effects of optogenetic stimulation of CST axons within the spinal cord in animal studies. One main barrier is a lack of validated methods for implanting light-delivery devices in the cervical spinal cord. Furthermore, blue light is conventionally used to activate blue-responsive opsins, however, it does not enable adequate tissue penetration to reach CST axons in the dorsal column. In this thesis, both challenges were studied. First, a reproducible surgical protocol was developed for the implantation of light-delivery (optoelectronic) devices in the rodent cervical spinal cord. Following one week of implantation, results demonstrate that the implant remained secured and did not cause adverse effects on motor function. Second, given that longer wavelengths of light penetrate deeper into tissue, the red-shifted opsin ChRMine was used to target the CST. Following transfection via adeno-associated virus (AAV) delivery to forelimb motor cortex (MCX), multiunit electrophysiological recordings were conducted to characterize the response profile of the CST to optogenetic stimulation at the axonal (in the spinal cord) and somatic (in MCX) level. Preliminary results demonstrate that stimulation induced local activation of CST neurons in MCX and of its axons in the spinal cord. Furthermore, modest increases in antidromic activity were recorded in MCX during CST stimulation in the spinal cord. Together, this work provides a toolkit for researchers to use in future work aimed at investigating activity-dependent plasticity mechanisms following selective optogenetic stimulation of the CST at the axonal level.

description: Adipose tissue autophagy (AT) is associated with human obesity and increased metabolic risk. Recent findings establish a role for autophagy in lipid metabolism. Here, we compared the expression of autophagy-related and lipolysis genes in human abdominal subcutaneous AT (SCAT) in overweight/obese subjects (n = 17) with or without impaired glucose tolerance in comparison with lean normal glucose tolerant individuals (n = 9), and investigated the association between AT autophagy and lipolysis. Human multipotent adipose-derived stem cells (hMADS) were used to investigate the effect of pharmacological HSL inhibition on changes in the autophagic flux. The expression of autophagy-related genes (ATG) 5, 7 and 12 in SCAT was significantly higher (p = 0.043, p = 0.015, p = 0.004, respectively) in overweight/obese compared to lean men, while expression of the classical lipases HSL (p = 0.092) and ATGL (p = 0.084) tended to be lower. ATG12 mRNA was positively correlated with BMI (r = 0.407, p = 0.039). ATG7 mRNA correlated positively with waist/hip ratio (WHR) (r = 0.420, p = 0.041), 2 h glucose concentration (r = 0.488, p = 0.011) and insulin (r = 0.419, p = 0.033). Multiple linear regressions revealed that ATG7 gene expression was positively related to 2 h glucose, independent of BMI, WHR and insulin. Gene expression interaction analysis showed that ATG7 mRNA negatively correlated with HSL (p<0.01) and ATGL mRNA expression (p<0.01). In line, treatment of differentiated hMADS with an HSL inhibitor increased LC3 accumulation, a marker of increased autophagic flux. Collectively, the present study demonstrated that a low expression of classical lipases in abdominal SCAT is accompanied by an increased expression of ATGs in overweight/obese subjects, which seems to be mainly related to glucose tolerance.

description: We address the problem of angular momentum transport in stellar radiative interiors with a novel semi-analytic spectral technique, using an eigenfunction series expansion, that can be used to derive benchmark solutions in hydromagnetic regimes with very high Reynolds number (10^7 - 10^8). The error arising from the truncation of the series is evaluated analytically. The main simplifying assumptions are the neglect of meridional circulation and of non-axisymmetric magnetic fields. The advantages of our approach are shown by applying it to a spin-down model for a 1 M_sun main-sequence star. The evolution of the coupling between core and envelope is investigated for different values of the viscosity and different geometries and values of the poloidal field. We confirm that a viscosity enhancement by 10^4 with respect to the molecular value is required to attain a rigid rotation in the core of the Sun within its present age. We suggest that a quadrupolar poloidal field may explain the short coupling time-scale needed to model the observed rotational evolution of fast rotators on the ZAMS, while a dipolar geometry is indicated in the case of slow rotators. Our novel semi-analytic spectral method provides a conceptually simple and rigorous treatment of a classic MHD problem and allows us to explore the influence of various parameters on the rotational history of radiative interiors.

description: In a recent paper Tettamanzi et al (2009 Nanotechnology \bf{20} 465302) describe the fabrication of superconducting Nb nanowires using a focused ion beam. They interpret their conductivity data in the framework of thermal and quantum phase slips below $T_c$. In the following we will argue that their analysis is inappropriate and incomplete, leading to contradictory results. Instead, we propose an interpretation of the data within a SN proximity model.

description: We report time-resolved measurements of Landau-Zener tunneling of Bose-Einstein condensates in accelerated optical lattices, clearly resolving the step-like time dependence of the band populations. Using different experimental protocols we were able to measure the tunneling probability both in the adiabatic and in the diabatic bases of the system. We also experimentally determine the contribution of the momentum width of the Bose condensates to the width of the tunneling steps and discuss the implications for measuring the jump time in the Landau-Zener problem.

description: The Hubbard model on a cube was revisited and extended by both nearest-neighbor (nn) Coulomb correlation and {nearest-neighbor} Heisenberg exchange. The complete eigensystem was computed exactly for all electron occupancies and all model parameters ranging from minus infinity to plus infinity. For two electrons on the cluster the eigensystem is given in analytical form. For six electrons and infinite on-site correlation U we determinded the groundstate and the groundstate energy of the pure Hubbard model analytically. For fixed electron numbers we found a multitude of ground state level crossings in dependence on the various model parameters. Furthermore the groundstates of the pure Hubbard model in dependence on a magnetic field h coupled to the spins are shown for the complete U-h plane. For the cubic cluster gas we calculated the density $n(μ,T,h)$ and the thermodynamical density of states from the grand potential. The ground states and the various spin-spin correlation functions are studied for both attractive and repulsive values of the three interaction constants. The anomalous degeneration lines are calculated. For the cases where these lines end in triple points we give the related parameter values. The influence of the nn-exchange and the nn-Coulomb correlation onto the anomalous degeneration is discussed.

Field of values analysis that includes the origin for preconditioned nonsymmetric saddle-point systems
Creators: name: Chen, Hao
Publisher: name: University of British Columbia

description: Nonsymmetric saddle-point systems arise in numerous significant physical applications, including the Navier-Stokes equations and Stokes-Darcy coupling problems. The solution of these systems frequently employs preconditioned Generalized Minimal Residual (GMRES) method. To analyze convergence speed using preconditioners, field-of-values (FOV) analysis serves as a useful theoretical tool. While existing FOV analysis effectively characterizes the convergence of preconditioned GMRES when zero is not included in the field of values of the preconditioned matrix, it cannot be applied when zero is contained in the FOV. Recent theoretical advances by Crouzeix and Greenbaum [Spectral sets: numerical range and beyond. SIAM Journal on Matrix Analysis and Applications, 40(3):1087–1101, 2019] show that a convex region with a circular hole is a spectral set. We apply this result to nonsymmetric systems and derive sufficient conditions for convergence of preconditioned GMRES independent of the matrix dimensions. We apply our results to preconditioned nonsymmetric saddle-point systems and demonstrate applicability to previously unaddressed families of block preconditioners: specifically, a block diagonal preconditioner and a block upper triangular preconditioner for left preconditioning. A limitation of our theory is that the preconditioned matrix is required to have a small skew-symmetric part in norm. Consequently, our analysis may not be applicable, for example, to fluid flow problems characterized by a small viscosity number. To demonstrate the practical effectiveness of our theoretical analysis, we conduct numerical experiments on Navier-Stokes and Stokes-Darcy systems, which validate the performance of the proposed preconditioners and show that the iteration counts are independent of the matrix dimensions.
