description: In quantum nanoelectronics, time-dependent electrical currents are built from few elementary excitations emitted with well-defined wavefunctions. However, despite the realization of sources generating quantized numbers of excitations, and despite the development of the theoretical framework of time-dependent quantum electronics, extracting electron and hole wavefunctions from electrical currents has so far remained out of reach, both at the theoretical and experimental levels. In this work, we demonstrate a quantum tomography protocol which extracts the generated electron and hole wavefunctions and their emission probabilities from any electrical current. It combines two-particle interferometry with signal processing. Using our technique, we extract the wavefunctions generated by trains of Lorentzian pulses carrying one or two electrons. By demonstrating the synthesis and complete characterization of electronic wavefunctions in conductors, this work offers perspectives for quantum information processing with electrical currents and for investigating basic quantum physics in many-body systems.

description: We present a new study of SU(3)-breaking corrections in hyperon vector form factors relevant for the extraction of Vus. A lattice quenched simulation has been performed, showing that it is possible to reach the required precision to extract SU(3)-breaking corrections in the regime of simulated masses. In order to perform the chiral extrapolation we calculated the chiral corrections to the vector form factor in HBChPT. Besides the one-loop O(p^2) contribution, we included also the subleading O(p^3) and O(1/M_B) corrections that, due to the Ademollo-Gatto theorem, are free from the contamination of unknown low energy constants. The results complete and correct previous calculations, and show that subleading corrections cannot be neglected. We also studied decuplet contributions within HBChPT and show that, in this case, the chiral expansion breaks down, rising doubts on the consistency of the theory.

title: Re-defining the Concept of Model Species: An Experimental Approach on a Range of Marine Animals
Creators: name: Mutalipassi, Mirko
Publisher: name: The Open University
Year: 2019

description: Scientific research extensively uses model organisms to address biological, ecological and evolutionary issues. Research employs a limited variety of organisms, ranging from bacteria to complex metazoans, to answer scientific questions and investigate natural aspects. We define “Model Organisms” this small fraction of the biological biodiversity. Generally, they are a simplified tractable system used to study larger scientific questions and to answer complex problems. Researchers expect that results obtained through experiments on these MOs will be applicable to other, more complex, organisms, or to complex communities and ecosystems. Model organisms are sometimes a scarcely representative sample of the global physiological, biochemical and genetic biodiversity and the answers that they can provide could not be easily applicable and transferred to other species. This Ph.D. thesis aims at re-defining the concept of “model species” on an objective point of view. I analysed a standard range of common characteristics that can describe and rank selected model organisms on the basis of their unique features, advantages and disadvantages. I have taken into consideration various “practical” features, such as size and feeding, their reproduction and the optimization of the culture techniques; their use in some scientific fields, such as chemical ecology, stress responses and apoptosis, and the availability of molecular tools and sequenced genomes. A set of laboratory analyses was applied to test the power of selected species to answer our questions and an arbitrary score was assigned to each species for each parameter according to our results and to the data available in scientific literature. The information collected was used to objectively rank the considered model organisms, for improving future experimental approaches and indicate a possible strategy to choose adequate models for selected research.

PHAGE THERAPY, THE BEST CHOICE TO OVERCOME ANTIBIOTIC RESISTANCE, BUT CAN NEVER REPLACE ANTIBIOTICS

Year: 2021
Subjects: subject: Microbiology
subject: FOS: Biological sciences

description: Phages are also known as bacteriophages which are normally viruses that infect and replicate within the bacteria. Phage therapy is the clinical use of these bacteriophages to treat infections caused by superbugs (bacteria that have acquired resistance against antibiotics). Phages when administered into bacteria, cause the lysis of the bacterial cells in the lytic phase of the phage life cycle. Phage therapy has acquired its importance in recent years after its successful use in managing some life-threatening infections and helped in saving lives. Phage therapy is currently being used as antimicrobial therapy in some western countries. this paper mainly discusses using phage therapy in treating infections caused by superbugs, and also discusses what measures should be taken by different countries to successfully introduce phage therapy in clinical use. Apart from this phage therapy has got some disadvantages which show that phage therapy can never be an effective alternative for antibiotics. We conclude that phage therapy can be the best choice for treating infections caused by superbugs, where antibiotics can’t work but can’t be used again once used before in a particular patient.
Operator-Based Truncation Scheme Based on the Many-Body Fermion Density Matrix

description: In [S. A. Cheong and C. L. Henley, cond-mat/0206196 (2002)], we found that the many-particle eigenvalues and eigenstates of the many-body density matrix $ρ_B$ of a block of $B$ sites cut out from an infinite chain of noninteracting spinless fermions can all be constructed out of the one-particle eigenvalues and one-particle eigenstates respectively. In this paper we developed a statistical-mechanical analogy between the density matrix eigenstates and the many-body states of a system of noninteracting fermions. Each density matrix eigenstate corresponds to a particular set of occupation of single-particle pseudo-energy levels, and the density matrix eigenstate with the largest weight, having the structure of a Fermi sea ground state, unambiguously defines a pseudo-Fermi level. We then outlined the main ideas behind an operator-based truncation of the density matrix eigenstates, where single-particle pseudo-energy levels far away from the pseudo-Fermi level are removed as degrees of freedom. We report numerical evidence for scaling behaviours in the single-particle pseudo-energy spectrum for different block sizes $B$ and different filling fractions $\nbar$. With the aid of these scaling relations, which tells us that the block size $B$ plays the role of an inverse temperature in the statistical-mechanical description of the density matrix eigenstates and eigenvalues, we looked into the performance of our operator-based truncation scheme in minimizing the discarded density matrix weight and the error in calculating the dispersion relation for elementary excitations. This performance was compared against that of the traditional density matrix-based truncation scheme, as well as against a operator-based plane wave truncation scheme, and found to be very satisfactory.

description: Given a complete real-valued field $k$ of residue characteristic zero, we study properties of a differential form $ω$ on a smooth proper $k$-analytic curve $X$. In particular, we associate to $(X,ω)$ a natural tropical reduction datum combining tropical data of $(X,ω)$ and algebra-geometric reduction data over the residue field $\widetilde{k}$. We show that this datum satisfies natural compatibility condition, and prove a lifting theorem asserting that any compatible tropical reduction datum lifts to an actual pair $(X,ω)$. In particular, we obtain a short proof of the main result of a work [BCGGM20] by Bainbridge, Chen, Gendron, Grushevsky, and Möller.

description: Context: Quality requirements (QRs) are a topic of constant discussions both in industry and academia. Debates entwine around the definition of quality requirements, the way how to handle them, or their importance for project success. While many academic endeavors contribute to the body of knowledge about QRs, practitioners may have different views. In fact, we still lack a consistent body of knowledge on QRs since much of the discussion around this topic is still dominated by observations that are strongly context-dependent. This holds for both academic and practitioners' views. Our assumption is that, in consequence, those views may differ. Objective: We report on a study to better understand the extent to which available research statements on quality requirements, as found in exemplary peer-reviewed and frequently cited publications, are reflected in the perception of practitioners. Our goal is to analyze differences, commonalities, and context-dependent grey areas in the views of academics and practitioners to allow a discussion on potential misconceptions (on either sides) and opportunities for future research. Method: We conducted a survey with 109 practitioners to assess whether they agree with research statements about QRs reflected in the literature. Based on a statistical model, we evaluate the impact of a set of context factors to the perception of research statements. Results: Our results show that a majority of the statements is well respected by practitioners; however, not all of them. When examining the different groups and backgrounds of respondents, we noticed interesting deviations of perceptions within different groups that may lead to new research questions. Conclusions: Our results help identifying prevalent context-dependent differences about how academics and practitioners view QRs and pinpointing statements where further research might be useful.

description: We present XEM, an eXplainable-by-design Ensemble method for Multivariate time series classification. XEM relies on a new hybrid ensemble method that combines an explicit boosting-bagging approach to handle the bias-variance trade-off faced by machine learning models and an implicit divide-and-conquer approach to individualize classifier errors on different parts of the training data. Our evaluation shows that XEM outperforms the state-of-the-art MTS classifiers on the public UEA datasets. Furthermore, XEM provides faithful explainability-by-design and manifests robust performance when faced with challenges arising from continuous data collection (different MTS length, missing data and noise).

Large-N_f behavior of the Yukawa model: analytic results

Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: We investigate the Yukawa model in which $N_f$ fermions are coupled with a scalar field $ϕ$ through a Yukawa interaction. The phase diagram is rather well understood. If the fermions are massless, there is a chiral transition at $T_c$: for $T < T_c$ chiral symmetry is spontaneously broken. At $N_f=\infty$ the transition is mean-field like, while, for any finite $N_f$, standard arguments predict Ising behavior. This apparent contradiction has been explained by Kogut et al., who showed by scaling arguments and Monte Carlo simulations that in the large-$N_f$ limit the width of the Ising critical region scales as a power of $1/N_f$, so that only mean-field behavior is observed for $N_f$ strictly equal to infinity. We will show how the results of Kogut et al. can be recovered analytically in the framework of a generalized $1/N_f$ expansion. The method we use is a simple generalization of the method we have recently applied to a two-dimensional generalized Heisenberg model.

description: Thermal inversions have long been predicted to exist in the atmospheres of ultra-hot Jupiters. However, detection of two species thought to be responsible -- TiO and VO -- remain elusive. We present a search for TiO and VO in the atmosphere of the ultra-hot Jupiter WASP-121b ($T_\textrm{eq} \gtrsim 2400$ K), an exoplanet already known to show water features in its dayside spectrum characteristic of a temperature inversion as well as tentative evidence for VO at low-resolution. We observed its transmission spectrum with UVES/VLT and used the cross-correlation method -- a powerful tool for the unambiguous identification of the presence of atomic and molecular species -- in an effort to detect whether TiO or VO were responsible for the observed temperature inversion. No evidence for the presence of TiO or VO was found at the terminator of WASP-121b. By injecting signals into our data at varying abundance levels, we set rough detection limits of $[\text{VO}] \lesssim -7.9$ and $[\text{TiO}] \lesssim -9.3$. However, these detection limits are largely degenerate with scattering properties and the position of the cloud deck. Our results may suggest that neither TiO or VO are the main drivers of the thermal inversion in WASP-121b, but until a more accurate line list is developed for VO, we cannot conclusively rule out its presence. Future work will search for finding other strong optically-absorbing species that may be responsible for the excess absorption in the red-optical.

description: Quantum cascade detectors (QCD) are unipolar infrared devices where the transport of the photo excited carriers takes place through confined electronic states, without an applied bias. In this photovoltaic mode, the detector's noise is not dominated by a dark shot noise process, therefore, performances are less degraded at high temperature with respect to photoconductive detectors. This work describes a 9 um QCD embedded into a patch-antenna metamaterial which operates with state-of-the-art performances. The metamaterial gathers photons on a collection area, Acoll, much bigger than the geometrical area of the detector, improving the signal to noise ratio up to room temperature. The background-limited detectivity at 83 K is 5.5 x 10^10 cm Hz^1/2 W^-1, while at room temperature, the responsivity is 50 mA/W at 0 V bias. Patch antenna QCD is an ideal receiver for a heterodyne detection set-up, where a signal at a frequency 1.4 GHz and T=295 K is reported as first demonstration of uncooled 9um photovoltaic receivers with GHz electrical bandwidth. These findings guide the research towards uncooled IR quantum limited detection.

description: The study was designed to assess the environmental and health risks arising from intensive poultry production in Kwara State, Nigeria. A total of 120 poultry farmers in Kwara State under the Poultry Association of Nigeria (PAN) were selected randomly for the study, and structured questionnaires were administered. The data collected were analyzed using descriptive statistics, chi-square test, and the linear regression. The study revealed that about 79.5% of the poultry farmers were literate, having completed at least a tertiary educational level. In addition, the results showed that the environmental and health issues were significant during production and processing. It was further revealed that the type of battery cage used and educational level of the farmers were positively significant, while the year of establishment was negatively significant when it comes to the adoption practices. This implies that the higher the level of education, the more likely farmers adopt improved practices. Moreover, it was observed that the majority of the poultry farmers do not abide by the environmental and public health laws and regulations; therefore, it is recommended that government should enforce strict supervisory agencies of the sanitation/health policies aiming at environmental preservation and protection.

description: The objective of this report is to investigate the possibility of determining open‐water propeller characteristics using Computational Fluid Dynamics (CFD). The propeller used in the current investigation is the four‐bladed propeller as used for the benchmark KRISO Very Large Crude Carrier 2 (KVLCC2) hull. The computed open‐water characteristics are not part of the CFD submission of Flanders Hydraulics Research (FHR) for Workshop on Verification and Validation of Ship Manoeuvring Simulation Methods (SIMMAN).Computations are executed according to the specifications of the International Towing Tank Conference (ITTC), where the angular velocity of the propeller remains constant and results are computed for a range of advance ratios ? by altering the forward velocity of the propeller. This contrasts with the recommendations of NUMECA for open‐water computations, where the forward velocity is held constant, and the advance ratio is changed by altering the angular velocity of the propeller. Computations are executed in a rotating frame of reference which allows for larger time steps than in a fixed frame of reference. The by NUMECA recommended time step values were however not strict enough for low values of the advance ratio: the smallest value used is 1/8 of the recommended value. A comparison between the numerical results and the reference values shows a good agreement.This type of computation could be used in the future as an alternative to experimentally determined open‐water propeller characteristics if a solution is found for the slow convergence at ? = 0.

description: We investigate the occurrence of multicritical points under pressure and magnetic field in a model that describes two 5f bands (of either $α$ or $β$ characters) which hybridize with a single itinerant conduction band. The 5f-electrons interact through Coulomb and exchange terms. The AF order parameter is a Néel vector, which is assumed to be fixed by an Ising anisotropy. The applied magnetic field is transverse to the anisotropy axis. Without field, our results for the temperature - pressure phase diagram show that, at low temperatures, a first-order phase transition occurs between two distinct antiferromagnetic phases, AF$_1$ and AF$_2$, as the pressure is increased. The two phases are characterized by the gaps of bands $α$ and $β$ given by $Δ_α$ and $Δ_β$, respectively. The AF$_1$ phase occurs when $Δ_β>Δ_α>0$, while in the AF$_2$ phase, the gaps satisfy $Δ_α>Δ_β>0$. The application of a magnetic field produces a drastic change in the phase diagram. The AF1 and AF2 phases separate with the latter acquiring a dome shape which is eventually suppressed for large values of the applied field. The evolution of the phase diagram under pressure, without and with magnetic field, shows the presence of multicritical points. Our results show that the evolution of these multicritical points by the simultaneous application of pressure and field is also drastic with the suppression of some multicritical points and the emergence of others ones. We believe that these results may have relevance for the growing field of multicritical points (classical and quantum) in the physics of Uranium compounds.

description: I study the Ds(2317) and Ds(2457) discovered at BABAR, CLEO and BELLE, and find that they belong to a class of strange S=-1 tetraquarks and pentaquarks, which is equivalent to the class of kaonic molecules bound by short range attraction. In this class of hadrons a kaon is strongly trapped by a s-wave meson or baryon. To describe this class of multiquarks the Resonating Group Method is applied to a standard quark model with chiral symmetry breaking, and the short range kaon-meson(baryon) interactions are extracted. A criterion is derived to classify the attractive channels. I conclude that the mesons Bs(0+), Bs(1+), and the baryons Omega cc, Omega cb, Omega bb clearly belong to the new hadronic class of the Ds(2317) and Ds(2457). The hadrons f0(980), Lambda, Sigma c, Sigma b possibly belong to a related family.

The renormalisation of the theory to second order in the scalar self-coupling pursued herein involves explicit calculations of up to third loop-order and reveals that, in addition to the renormalisation of the scalar self-coupling and scalar field, the removal of all divergences necessitates the introduction of conformally non-invariant counterterms proportional to $ RΦ^2$ and $ KΦ^2$ in the bare scalar action as well as counterterms proportional to $ RK^2$, $ R^2$ and $ RK$ in the gravitational action. The substantial backreaction effects and their relevance to the renormalisation procedure are analysed.

title: The Reception in Transylvania of Karl Barth's Theology of the Word of God
Creators: name: Kovács, József
Publisher: name: The Open University

description: The influence of Karl Barth's theology on the Reformed Church of Romania was the major theological development of the twentieth century history of doctrines in the Protestant churches of Transylvania. The Hungarian speaking Reformed Church in Romania, after World War I, due to border changes, became isolated from her sister church in Hungary and came to play an important role in preserving Hungarian culture and national existence. After the failure of liberal theology a number a ways were attempted to bring renewal to church life. This thesis focuses on the process of reception of Karl Barth's theology, which was read against the background of a confessional Calvinism, the Transylvanian form of the Calvin-renaissances in Europe. Since the process of the reception of Karl Barth's theology in Transylvania was halted with the emergence of Communism in Central and Eastern Europe at the mid 1940s, this thesis concentrates mainly on the 1920s and 1930s. A special attention is given to the theology of Sandor Tavaszy, professor at the Protestant Theological Institute in Kolozsvar (Cluj) who had a pioneering role in popularising Karl Barth's theology among the Hungarians. The contextual study of the reception of Karl Barth's theology of the Word of God refers to the general situation of the Hungarians in Romania after World War I, that of the relationship between church and society and the analysis of the philosophical and theological context. To make the understanding of Barth' reception easier three models of initial responses are presented. The emerging theology resulting from the impact of Barthian thought on indigenous thinking is analysed and compared with Barth's own thinking. The research draws the attention of the reader that to benefit from the full potential impact of Barth's theology, a consistently following of Karl Barth's theological development is needed. The conclusion of the thesis points towards the possibility of constructing a theology of culture along the lines of Barthian thinking, a theology which is, as always was, a serious task for the Reformed community of Transylvania.

description: We investigate the constraints on quintessence arising from both renormalisable and non-renormalisable couplings where the 5d Planck mass is around the TeV scale. The quintessence field vacuum expectation value is typically of order the 4d Planck mass while non-renormalisable operators are expected to be suppressed by the 5d Planck mass. Non-renormalisable operators are therefore important in computing the 4d effective quintessence potential. We then study the quantum corrections to the quintessence potential due to fermion and graviton loops. The tower of Kaluza-Klein modes competes with the TeV-scale cut-off, altering the graviton contribution to the vacuum polarization of quintessence. Nevertheless we show that, as in four dimensions, the classical potential is stable to such radiative corrections.

title: Similarities Between Acquired Dyslexia, Developmental Dyslexia and Early Reading
Creators: name: King, Bernardine
Publisher: name: The Open University
Year: 2006

description: This thesis compared responses to onsets and offsets of stimuli (visual, auditory, phonemic and orthographic) in children with developmental dyslexia (DDs), adults with acquired dyslexia (ADs) and early readers (ERs). Similarities were observed between the reading characteristics of ERs who demonstrated an incomplete mapping between letters and sounds and a group of ADs. Cluster analysis identified children of 'low', 'intermediate' (IRs) and 'high' alphabetic ability in two samples of early readers (4 to 6-year-olds). IRs showed an alphabetic profile similar to those expected of Ehri's (1995) partial alphabetic phase. There was a lack of discrimination between auditory onset and offset in IRs, DDs and ADs that suggested a basis for problems in establishing reliable phonological representations. DDs showed deficits in sensitivity to the first of contiguous trios of tones and of phonemes, and to the last in a series of three lights, compared to chronological age controls (CAs). DDs were similar to RAs (reading age controls) on most tasks. ADs were slower and less accurate in temporal processing tasks than their CAs but showed similarities to their RAs. This supports the notion of a cognitive delay in developmental dyslexia and a regression to an immature cognitive state in acquired dyslexia. Cluster analysis of ERs, ADs and DDs on alphabetic measures demonstrated that, whereas many of the DDs (10/22) were able to progress to a more advanced phase of reading, most (8/9) ADs clustered with the IRs, suggesting that many ADs may be trapped within a cognitive state comparable to Ehri's partial alphabetic phase. A cognitive model of both acquired and developmental dyslexia is proposed whereby, despite different biological causes for the two conditions, a failure to fully complete alphabetic links due to the dominance of the whole-word level of representation may form the basis of both dyslexias.

description: In this paper the researchers tried to study the status of tourism and rural tourism economy in Iran the condition of entry and exit of tourists in Iran, as well as the inhibiting factors affecting their positive impacts on Iran economic status. To achieve this objective, the researchers used documentary research methods. In addition, the researchers used a field research method based on the data obtained from a questionnaire in an attempt to find the inhibiting factors affecting positive impacts of tourism and rural tourism on Iran economics. The population of this study involve in tourism and rural tourism authorities. The sample of the population consist of 119. The statistical methods used in the study include the non-parametric statistics (Kolmogrove Smirnove). Findings revealed that Iran’s percent share of tourism contribution to GDP in the years 2003-2014 was very low and its changes in these years have been disproportionate. No special information and detailed statistics were presented that have helped clarified the status of rural tourism and rural tourists in Iran. The first five priorities in the field of inhibiting factors affecting positive impacts of tourism on Iran economics were lack of major plans and policies for tourism and rural tourism development, weak cooperation between the government, private sector and local people in planning, managing the tourism and rural tourism projects, frequent change in the authorities of cultural heritage, handicraft and tourism organization, lack of correct criteria for choosing managers and executive directors, and the effects of the sanctions on tourism programs. Furthermore, political factors were found to be important in regard to their effect on the situation of tourism economics in Iran.

description: Fermilab operates several clusters for lattice gauge computing. Minimal manpower is available to manage these clusters. We have written a number of tools and developed techniques to cope with this task. We describe our tools which use the IPMI facilities of our systems for hardware management tasks such as remote power control, remote system resets, and health monitoring. We discuss our techniques involving network booting for installation and upgrades of the operating system on these computers, and for reloading BIOS and other firmware. Finally, we discuss our tools for parallel command processing and their use in monitoring and administrating the PBS batch queue system used on our clusters.

title: Human metapneumovirus: Investigation of epidemiology strain diversity and human immune response
Creators: name: Mitchell, Judy Anne
Publisher: name: The Open University
Year: 2006

description: Human metapneumovirus (hMPV) is a newly described respiratory virus belonging to the Paramyxoviridae family, first identified in respiratory samples of children with acute respiratory tract infection (ARTI). Since its discovery hMPV has been associated with ARTI worldwide, however, important questions remain as to the contribution of hMPV to respiratory illness, and its impact on public health.

Extensive surveillance of hMPV within different populations of the United Kingdom (UK) demonstrates it is an important cause of ARTI in the elderly, and influenza like illness (ILI) in people of all ages in the community. Furthermore it is a frequent cause of hospitalisation in young children.

Recombinant baculovirus expressed hMPV nucleocapsid protein (N) proved to be a useful source of antigen for the development of an hMPV specific ELISA. Analysis of age stratified sera from the UK indicates that a majority of children are infected by the age of 6 years with primary infections occurring throughout infancy. Virtually all adults have detectable levels of hMPV antibody; however, reinfection with hMPV is common, raising questions concerning acquisition and duration of immunity.

Sequence analysis of the attachment glycoprotein (G), shows a high degree of nucleotide and amino acid variation and extensive glycosylation. Frequent nucleotide insertions or deletions result in frame shift mutations which can drastically alter the appearance of the protein and often results in premature termination. Antibody recognition of hMPV G is likely to be highly strain specific and dependent on the extent of glycosylation, suggesting an involvement of G in immune evasion.

Phylogenetic analysis of hMPV G gene sequence shows that whilst a large degree of variation exists within this gene, strains circulating within the UK are genetically similar to strains circulating elsewhere in the world, and similar strains circulate throughout different years and populations within the UK.
