title: The function and evolution of the response regulator CtrA in Rhodobacter capsulatus and Alphaproteobacteria
Creators: name: Kollipara, Roshni S.
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: Rhodobacter capsulatus is a model organism for studying gene transfer agents (GTAs). GTAs are a unique facilitator of gene transfer in prokaryotes. The DNA binding response regulator CtrA plays a key role in modulating GTA activity in R. capsulatus, as well as flagellar biosynthesis and cell motility. CtrA is an OmpR/PhoB response regulator with an N-terminal receiver domain and a C-terminal transcriptional regulator domain. One unusual aspect of CtrA function in R. capsulatus is that it regulates gene expression in both the phosphorylated and nonphosphorylated forms. Using overlap extension PCR, the constructs for expression of three of different versions of ctrA in R. capsulatus were prepared: wild type, phosphomimetic, nonphosphorylatable. These constructs place the genes under the control of the R. capsulatus puf promoter for high level of expression and the encoded proteins have 6×-histidine tags for purification in studies aimed at determination of the DNA binding sites of the different versions of CtrA. Horizontal gene transfer is an interesting way that bacteria can increase their genetic diversity. In this work, the distribution of ctrA in the Alphaproteobacteria was examined and evidence of horizontal gene transfer of this gene was found. Using phylogenetic analyses, several instances of apparent misclassification of alphaproteobacteria to the wrong orders were found and one candidate ctrA horizontal gene transfer event that may have occurred in an ancestral bacterium that subsequently evolved into one lineage within the order Sphingomonadales was found.

subject: Public health not elsewhere classified

description: An interrupted time series study is a type of non-randomised study that allows researchers to quantify the immediate and long-term impact of interruptions like public health policies. For example, the impact of a mass media campaign on HIV testing rates. The results from multiple interrupted time series may be combined using a statistical technique called meta-analysis. However, there are many meta-analysis methods and no research on how these methods perform when combining interrupted time series studies. This thesis describes how interrupted time series are combined in the published literature and evaluates how well the statistical methods perform.

description: Microscopic signatures of nuclear ground-state shape phase transitions in Nd isotopes are studied using excitation spectra and collective wave functions obtained by diagonalization of a five-dimensional Hamiltonian for quadrupole vibrational and rotational degrees of freedom, with parameters determined by constrained self-consistent relativistic mean-field calculations for triaxial shapes. As a function of the physical control parameter -- the number of nucleons, energy gaps between the ground state and the excited vibrational states with zero angular momentum, isomer shifts, and monopole transition strengths, exhibit sharp discontinuities at neutron number N=90, characteristic of a first-order quantum phase transition.

description: Omega-5-gliadin (O5G) allergy causes the unique syndrome of wheat-dependent exercise-induced allergy. I studied 43 adults with this condition and compared the findings to those with peanut allergy.
In distinction to peanut allergy, O5G allergy was of adult-onset, associated with less atopic burden and more frequent reactions. The frequency of allergic reactions reduced after diagnosis but did not differ according to management strategy. Allergic reactions in O5G allergy were often related to deliberate ingestion or unexpected exercise, whilst those associated with peanut allergy were more often caused by accidental exposure and eating away from home.

title: Following stones: navigating the landscape in northern Labrador
Creators: name: Wilson, Sarah M.
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: The landscape in northern Labrador is dotted with inuksuit (human-made rock stacks used for navigation, commemoration, hunting, and more) signifying a connection between people and the land. My theoretical framework considers the traditional knowledge, or way of knowing, respecting, and using resources from the environment, of Inuit in Labrador to understand ways of memorializing the landscape and place. Through an aerial survey via drone, this project involves collecting photogrammetric data to reconstruct 3D and digital elevation models of different features and sites. This project serves as an examination of the application of data that drones can collect in summer and winter settings. Geographic information systems (QGIS and ArcGIS) aid in examining the relation of inuksuit to topography and other features. This project looks at the relationship between humans and their surroundings, movement across vast spaces, methods of navigation, and connection to land to argue for the importance of protecting cultural landscapes.

A dynamical approach to link low energy phases with leptogenesis

Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: If lepton masses and mixings are explained by a flavour symmetry in seesaw model which leads to U_{e3}=0 at leading order, we find that, under reasonable assumptions, a future observation of low energy leptonic CP violation implies, barring accidental cancellations, a lepton asymmetry both in flavoured leptogenesis and in its one-flavour approximation. We explicitly implement this approach with a predictive seesaw model for Tri-Bimaximal Mixing (TBM) and show how cosmological baryon asymmetry can be directly trigged by low energy phases appearing in $U_{e3}$. Thanks to this direct correlation we can derive a lower bound on the reactor angle θ_{13}: \sin^2 θ_{13} \gtrsim 0.005.

CARMENES

description: Stellar activity poses one of the main obstacles for the detection and characterisation of exoplanets around cool stars, as it can induce radial velocity (RV) signals that can hide or mimic the presence of companions. Several activity indicators are routinely used to identify activity-related signals in RV measurements, but not all indicators trace exactly the same effects, nor are any of them always effective in all stars. In this work, we evaluate the performance of a set of common spectroscopic activity indicators for 98 M dwarfs observed with CARMENES. We find that different indicators behave differently depending on the mass and activity level of the target star. In addition, we also observe that stars at the low-mass end of the sample show the lowest RV scatter, which could potentially hint at different manifestations of activity compared to higher-mass stars, as well as being better candidates for planet searches. Overall, our results show that when assessing the origin of an RV signal, it is critical to take into account a large set of indicators, or at least the most effective ones considering the characteristics of the star, as failing to do so may lead to false planet claims.
The curious case of GJ 9689 b: A super-Earth with a period close to half the stellar rotation period.
Creators: name: Maldonado, J.
Publisher: name: Zenodo
Year: 2021

description: Low-mass stars are optimal targets around which to search for small rocky planets with the potential capabilities of hosting life. However, the detection of truly Earth twins is hampered by the short-term stellar activity of the host stars. The evolution and decay of active regions has a characteristic timescale comparable with the stellar rotation period and disentangling ‘true’ Keplerian signals from stellar variations is highly complex. In this contribution we discuss several complementary and imaginative approaches used to study the radial velocity variations observed in low-mass stars. In particular, we discuss the case of the M dwarf GJ 9689. This is an interesting case of study, as the proposed planetary period is very close to half the stellar rotation period.

description: In this paper, we analyze the temporal evolution of the age-dependent force of infection and incidence of rubella, after the introduction of a very specific vaccination programme in a previously nonvaccinated population where rubella was in endemic steady state. We deduce an integral equation for the age-dependent force of infection, which depends on a number of parameters that can be estimated from the force of infection in steady state prior to the vaccination program. We present the results of our simulations, which are compared with observed data. We also examine the influence of contact patterns among members of a community on the age-dependent intensity of transmission of rubella and on the results of vaccination strategies. As an example of the theory proposed, we calculate the effects of vaccination strategies for four communities from Caieiras (Brazil), Huixquilucan (Mexico), Finland and the United Kingdom. The results for each community differ considerably according to the distinct intensity and pattern of transmission in the absence of vaccination. We conclude that this simple vaccination program is not very efficient (very slow) in the goal of eradicating the disease. This gives support to a mixed strategy, proposed by Massad et al., accepted and implemented by the government of the State of Sao Paulo, Brazil.

description: We study the kinetics for the search of an immobile target by randomly moving searchers that detect it only upon encounter. The searchers perform intermittent random walks on a one-dimensional lattice. Each searcher can step on a nearest neighbor site with probability "alpha", or go off lattice with probability "1 - α" to move in a random direction until it lands back on the lattice at a fixed distance L away from the departure point. Considering "alpha" and L as optimization parameters, we seek to enhance the chances of successful detection by minimizing the probability P_N that the target remains undetected up to the maximal search time N. We show that even in this simple model a number of very efficient search strategies can lead to a decrease of P_N by orders of magnitude upon appropriate choices of "alpha" and L. We demonstrate that, in general, such optimal intermittent strategies are much more efficient than Brownian searches and are as efficient as search algorithms based on random walks with heavy-tailed Cauchy jump-length distributions. In addition, such intermittent strategies appear to be more advantageous than Levy-based ones in that they lead to more thorough exploration of visited regions in space and thus lend themselves to parallelization of the search processes.

description: Musculoskeletal conditions are highly prevalent and a major cause of disability worldwide. Clinical practice guidelines have been developed to manage these conditions, however, an evidence-practice gap exists. This thesis provides a comprehensive exploration of the patients’ perspective to bridge this gap by identifying patients’ perceived needs of health services, health information and non-medical services for the management of common musculoskeletal conditions. This thesis also identified modifiable risk factors for low back pain, the most common musculoskeletal condition. The findings from this thesis have the potential to inform better approaches to the management of musculoskeletal conditions.

description: A key principle of the extended phenotype concept is that the benefit of the structures that an animal builds exceeds its cost. However, some contexts may enhance the costs of structures that often represent a benefit, reversing their adaptive nature. In leaf-cutting ant nests, thatched mounds are extended phenotypes that offer a stable microclimate for the growth of the fungus culture. We hypothesized that fires will affect the species that build external, easily flammable thatch mounds (Acromyrmex lobicornis) more than colonies that build subterranean nests in the less-flammable bare ground (Amoimyrmex striatus). We use a stochastic matrix demographic model parameterized with 4 years of data in pre and post-fire scenarios. Before fires, Ac. lobicornis showed higher stochastic population rate (λs) than Am. striatus. However, fire frequency every 2 years completely reversed this trend, showing population decline only in Ac. lobicornis. Small nests were the stage that most contributed to λs and the most sensitive in all the species and fire scenarios. This illustrates a novel effect of disturbances; the reversion of the adaptive nature of extended phenotypes, which may have strong consequences on population dynamics and assemblage structure through the invert of dominance relationships.

description: Use of semi-leptonic decays has become standard in constraining the Unitarity Triangle. Bearing in mind that precise calculations of these are very challenging, we propose an entirely new approach. In particular the |Vcb| + epsilon_K constraint, which depends extremely sensitively on Vcb in the traditional method, is replaced by the interplay between epsilon_K, BR(B ->tau nu) and Delta M_Bs. It is found that even in this method tensions with the Standard Model persist at the ~1.8 sigma level. Furthermore, improvements on the B -> tau nu branching ratio and on the lattice determination of f_Bs Bs^(1/2) can increase the effectiveness of this method significantly.

description: Wide binary stars with similar components hosting planets provide an interesting opportunity for exploring the star-planet chemical connection. Here, we present a detailed characterization of the solar-type stars in the WASP-160 binary system. No planet has been reported yet around WASP-160A while WASP-160B is known to host a transiting Saturn-mass planet, WASP-160B b. For this planet, we also derive updated properties from both literature and new observations. Furthermore, using TESS photometry, we constrain the presence of transiting planets around WASP-160A and additional ones around WASP-160B. The stellar characterization includes, for the first time, the computation of high-precision differential atmospheric and chemical abundances based on high-quality spectra. Our analysis reveals evidence of a correlation between the differential abundances and the condensation temperatures of the elements. In particular, we find both a small but significant deficit of volatiles and an enhancement of refractory elements in WASP-160B relative to WASP-160A. After WASP-94, this is the second stellar pair among the shortlist of planet-hosting binaries showing this kind of anomalous chemical pattern. We discuss that the formation of WASP-160B b and late accretion of rocky material by its host star, likely triggered by the inward migration of this giant planet, could explain the observed chemical pattern. Alternative scenarios involve the formation of additional giant planets around WASP-160B and rocky objects around WASP-160A. Full details about this work can be found in Jofré et al. (2021; arXiv:2109.04590).
title: Auditory and linguistic processing in autism: evidence from production and perception
Creators: name: Veic, Anamarija
Publisher: name: University of Reading
Year: 2023

description: Autistic individuals may possess enhanced auditory abilities, but their language profiles are highly 
heterogeneous. Such inconsistent results, to a certain extent, can be explained by not controlling 
for confounding variables (e.g., cognitive abilities), and by not using closely matched stimuli 
across domains. The current thesis comprised three main aims: (1) to investigate whether autistic 
individuals will show superior performance at the tone and intonation perception in a foreign tone 
language compared to controls; (2) to explore the differences in groups’ comprehension abilities 
whilst recalling sentences in different conditions (e.g., spoken vs sung sentences); and (3) to 
investigate autistic individuals’ expectancy on both perceptual and production tasks using closely 
matched linguistic and melodic stimuli. 
In Study 1, no group differences were found on any Mandarin tone or intonation discrimination 
task, and we did not identify a subgroup of autistic individuals with superior perceptual abilities. 
Study 2 preliminary findings showed no group differences when recalling sentences, whereas the 
results from an online study showed impaired sentence recall in the autism group compared to 
controls. In Study 3 autistic individuals produced more ‘the most frequent’ responses on the 
melody completion task in the high expectancy but not in the low expectancy condition, compared 
to controls. Both groups performed equally well on the sentence completion task across conditions, 
whereas overall, autistic participants produced more NA responses than controls. However, none 
of these differences reached significance after applying the Bonferroni correction. The groups did 
not differ in their ratings across the tasks (sentences/melodies) or the conditions (high/low 
expectancy) and did not differ in their RTs across the tasks/conditions. 
The findings of this thesis provide evidence of either intact or enhanced auditory processing and 
either intact or impaired speech processing in autism. Future studies are warranted to further 
explore the underlying processes of production and perception processing in autism.
title: Motive und Coping-Strategien beim Free-Solo-Klettern
Creators: name: Gabriel, Alexander

description: Die Popularität des „Free Solo Kletterns“ ohne Sicherungen scheint in den letzten Jahren inner-halb der Klettercommunity zugenommen zu haben. Obwohl die Zahl der Aktiven Free-Solo-Kletter*innen eher gering eingeschätzt werden dürfte, ist diese Form des Kletterns durch Profi-Kletterer wie Alex Honnold oder Marx-André Leclerc medial sehr präsent. Insofern stellt sich die Frage, welche Motive zu der Ausübung dieser Risikosportart bewegen. Die Anreiztrias nach Rheinberg (1996) beschreibt in diesem Zusammenhang das Kompetenzerleben (Deci & Ryan, 2000) bzw. das Leistungsmotiv (Winter, 1994), die Bedrohungswahrnehmung bzw. das Sensationsseeking (Zuckerman, 1979) / Thrill (Zuckermann, 2007) und die Ungewöhnlichen Bewegungszustände (Caillolis, 1982) bzw. das Flow-Erleben (Csikszentmihalvi). Zusätzlich lassen sich die genannten drei Bereiche noch um die Faktoren Naturerleben, Freiheitserleben und Selbstbestimmung nach Brymer und Schweitzer (2013) erweitern um einen vorgegebenen Raster zur Beschreibung von Motiven für das Free-Solo Klettern zu erhalten. In einem zweiten Schritt wird nach den Coping-Strategien (Kiemley-Gabbay & Lavallee, 2017) der Kletter*innen in Angstsituationen gefragt, um zu sehen, welche Strategien in Risikosituationen bewusst oder unbewusst angewendet werden. Bei dieser Forschungsarbeit handelt es sich um eine explorative Analyse mit qualitativen Interviews von sechs bis acht Free-Solo-Kletter*innen aus dem Amateur- und Profibereich, welche regelmäßig, ab dem vierten Schwierigkeitsgrad den Free-Solo-Kletterstil ausüben. Die Auswertung erfolgt mittels der Inhaltsanalyse nach Mayring und einer deskriptiven Auswertung. Dabei werden Textpassagen mit den oben genannten Rasterkategorien geclustert und nach Inhalt und Häufigkeit in einem Fazit ausgewertet. Ziel dieser Forschungsarbeit ist ein genaueres Bild über Motive und Angstregulationstechniken zu einer Risiko-Sportart zu bekommen, bei der ein einziger Absturz lebensgefährliche Folgen haben kann.

description: We present a detailed analysis of all archival INTEGRAL data of the accreting X-ray pulsar Vela X-1. We extracted lightcurves in several energy bands from 20 keV up to 60 keV. The lightcurves show that the source was found in very active as well as quiet states. During the active states several giant flares were detected. For these states spectra between 5 keV and 120 keV were obtained. The spectra of the active states were found to be significantly softer than those from the quiet states. We performed a statistical analysis of the flaring behavior. The resulting log-normal distribution of the intensity of Vela X-1 shows that the source spends most of the time at an average flux level of 300 mCrab but also that the distribution extends well up to more than 2.0 Crab.

description: This thesis includes studies of four novel influenza A subtypes which infected diverse population cohorts at various time points. The novel analytic approaches used facilitate better understanding of transmission and survival characteristics of influenza viruses in human populations, competition between influenza subtypes, and evolution of influenza A viruses over time via long-term selection of CD8+ T cell epitopes. This work has added new knowledge regarding influenza survival in the human population that may be useful in the development of ‘universal’ influenza vaccines based on CD8+ T cell immunogenic peptides and their potential population impact

description: Language learners learn the best when they are interested in the activities prepared by the teacher. Video lessons can be a great tool to engage learners and give them an opportunity to develop language skills through visual and audio stimuli. By choosing the right video material and by offering well-planned video lessons to students (students work with the video material for the whole lesson), we will be giving them an alternative (and often more entertaining) way to experience language outside of grammar explanations and textbook exercises.

description: When a person joins in an organization, he becomes authorize to take some decisions on behalf of that organization; means he is given some authority to exercise. After some time, on the basis of his performance in the organization, he is given promotion and he becomes eligible to exercise to some higher authorities. And further, he may get some higher promotion or he may leave the organization. So, during his stay in the organization, the authority of that person varies from the time he joins the organization until he/she leaves the organization. This paper presents the variation in authorities of a person in the organization. The method implements the queuing model to analyze the various people in the queue of their promotion and looks at various parameters like average waiting time etc.

description: A key principle of the extended phenotype concept is that the benefit of the structures that an animal builds exceeds its cost. However, some contexts may enhance the costs of structures that often represent a benefit, reversing their adaptive nature. In leaf-cutting ant nests, thatched mounds are extended phenotypes that offer a stable microclimate for the growth of the fungus culture. We hypothesized that fires will affect the species that build external, easily flammable thatch mounds (Acromyrmex lobicornis) more than colonies that build subterranean nests in the less-flammable bare ground (Amoimyrmex striatus). We use a stochastic matrix demographic model parameterized with 4 years of data in pre and post-fire scenarios. Before fires, Ac. lobicornis showed higher stochastic population rate (λs) than Am. striatus. However, fire frequency every 2 years completely reversed this trend, showing population decline only in Ac. lobicornis. Small nests were the stage that most contributed to λs and the most sensitive in all the species and fire scenarios. This illustrates a novel effect of disturbances; the reversion of the adaptive nature of extended phenotypes, which may have strong consequences on population dynamics and assemblage structure through the invert of dominance relationships.

Grid-based density functional calculation of many-electron systems
Creators: name: Roy, Amlan K
Publisher: name: arXiv
Year: 2010
Subjects: subject: Chemical Physics (physics.chem-ph)
subject: FOS: Physical sciences

description: Exploratory variational pseudopotential density functional calculations are performed for the electronic properties of many-electron systems in the 3D cartesian coordinate grid (CCG). The atom-centered localized gaussian basis set, electronic density and the two-body potentials are set up in the 3D cubic box. The classical Hartree potential is calculated accurately and efficiently through a Fourier convolution technique. As a first step, simple local density functionals of homogeneous electron gas are used for the exchange-correlation potential, while Hay-Wadt-type effective core potentials are employed to eliminate the core electrons. No auxiliary basis set is invoked. Preliminary illustrative calculations on total energies, individual energy components, eigenvalues, potential energy curves, ionization energies, atomization energies of a set of 12 molecules show excellent agreement with the corresponding reference values of atom-centered grid as well as the grid-free calculation. Results for 3 atoms are also given. Combination of CCG and the convolution procedure used for classical Coulomb potential can provide reasonably accurate and reliable results for many-electron systems.

The Importance of Edge Effects on the Intrinsic Loss Mechanisms of Graphene Nanoresonators

description: We utilize classical molecular dynamics simulations to investigate the intrinsic loss mechanisms of monolayer graphene nanoresonators undergoing flexural oscillations. We find that spurious edge modes of vibration, which arise not due to externally applied stresses but intrinsically due to the different vibrational properties of edge atoms, are the dominant intrinsic loss mechanism that reduces the Q-factors. We additionally find that while hydrogen passivation of the free edges is ineffective in reducing the spurious edge modes, fixing the free edges is critical to removing the spurious edge-induced vibrational states. Our atomistic simulations also show that the Q-factor degrades inversely proportional to temperature; furthermore, we also demonstrate that the intrinsic losses can be reduced significantly across a range of operating temperatures through the application of tensile mechanical strain.

description: Freezing is a fundamental physical phenomenon that has been studied over many decades; yet the role played by surfaces in determining nucleation has remained elusive. Here we report direct computational evidence of surface induced nucleation in supercooled systems with a negative slope of their melting line (dP/dT < 0). This unexpected result is related to the density decrease occurring upon crystallization, and to surface tension facilitating the initial nucleus formation. Our findings support the hypothesis of surface induced crystallization of ice in the atmosphere, and provide insight, at the atomistic level, into nucleation mechanisms of widely used semiconductors.

title: Die räumliche Strukturierung der Lebensführung in Wien
Creators: name: Liedl, Bernd
Year: 2023

description: Diese Arbeit untersucht den Zusammenhang von sozialer Lage und Lebensführung in Wien, wobei auch der räumliche Kontext des Wohnortes berücksichtigt wird. Während in den letzten Jahrzehnten die Strukturierung der Lebensführung Gegenstand intensiver Forschung und Debatten war, wird der räumliche Kontext innerhalb einer Stadt weniger berücksichtig. Aufbauend auf den theoretischen und methodischen Arbeiten von Otte (2008), wird ein Mehrebenenmodell auf Basis der Daten der Wiener Lebensqualitätsstudie geschätzt. Der Datensatz umfasst eine repräsentative Stichprobe der Wiener Wohnbevölkerung, die 35 räumlichen Einheiten zugerechnet werden können. Die Ergebnisse stützen die These, dass die Lebensführung durch die soziale Lage – vor allem Einkommen, Bildung und Alter – strukturiert ist. Für den räumlichen Kontext kann zwar kein direkter Effekt, jedoch ein moderierender Effekt festgestellt werden: Mit dem räumlichen Kontext variiert der Effekt des Einkommens auf die Lebensführung. Diese Erkenntnisse können für den Umgang mit Aufwertungsprozessen in Stadtteilen fruchtbar gemacht werden.
