description: Hybrids affect vegetative development in silage corn and forage sorghum. Investigations wereconducted on the hybrid selection and impact on vegetative development for multiple irrigation treatments in Jordan. The study was carried out under the Norman Borlaug Fellowship during the 2017 season which demonstrated a suitable selection for forage growers. The first step required the selection of drought-tolerant hybrids. Five commercial seed lots (three of corn and two of sorghum) were tested. The second step involved planting hybrids under field conditions at Florida Agricultural and Mechanical University using a designed irrigation treatment and then evaluating the vegetative growth and development by measuring emergence rate index, seedling dry weight, tissue water content percentage, total leaf count, plant height, and fodder yield of the first harvest. Silage corn (6640VT3P) seed had lower water uptake and higher seedling dry weight aligned with a suitable seedling tissue water content and fodder yield of the first harvest. The superiority of silage corn (6640VT3P) may be attributed to hybrid vigor and its efficient water usage habit. These findings suggest that silage corn (6640VT3P) had a high impact on the vegetative development that could be selected and grown using irrigation treatment under extreme drought conditions identical to Jordan.

description: We consider a diatomic molecule driven by a linearly polarized laser pulse with a polarization axis rotating with a constant acceleration. This setup is referred to as optical centrifuge, and it is known to lead to high-angular momenta for the molecule (superrotor states) and, possibly, to dissociation. Here we elucidate the dynamical mechanisms behind the creation of superrotor states and their dissociation. We unravel the role of the various parameters of the laser field in these processes by considering reduced Hamiltonian models encapsulating the different phases in the creation of superrotor states, possibly leading to dissociation.

description: The phytochemical investigation on the leaves of Psidium guajava Linn. led to the isolation and identification of 18 compounds, including six guavinoside (1-6), four flavonoids (7-10), eight triterpenoids (11-17) and one lignans (18). All chemical structures were elucidated via NMR spectroscopic methods, and further supported by comparison with literature data. Compounds 12, 14, 16 and 18 was isolated from the Myrtaceae family for the first time. The chemotaxonomic significance of these compounds was also discussed based on their structure types, as well as compounds-genus/family network analysis. The results showed that there were close chemotaxonomic relationships among the Myrtaceae, Asteraceae, and Lamiaceae families. Guavinosides A-F could be considered as valuable chemotaxonomic markers of Myrtaceae family, while guavinosides C-F might serve as chemotaxonomic markers for distinguishing the P. guajava.

description: Phonon scattering at grain boundaries (GBs) is significant in controlling nanoscale device thermal conductivity. However, GBs could also act as waveguides for selected modes. To measure localized GB phonon modes, meV energy resolution is needed with sub-nm spatial resolution. Using monochromated electron energy loss spectroscopy (EELS) in the scanning transmission electron microscope (STEM) we have mapped the 60 meV optic mode across GBs in silicon at atomic resolution and compared it to calculated phonon densities of states (DOS). The intensity is strongly reduced at GBs characterised by the presence of five- and seven-fold rings where bond angles differ from the bulk. The excellent agreement between theory and experiment strongly supports the existence of localized phonon modes and thus of GBs acting as waveguides.

description: This paper considers the problem of data generation for MPC policy approximation. Learning an approximate MPC policy from expert demonstrations requires a large data set consisting of optimal state-action pairs, sampled across the feasible state space. Yet, the key challenge of efficiently generating the training samples has not been studied widely. Recently, a sensitivity-based data augmentation framework for MPC policy approximation was proposed, where the parametric sensitivities are exploited to cheaply generate several additional samples from a single offline MPC computation. The error due to augmenting the training data set with inexact samples was shown to increase with the size of the neighborhood around each sample used for data augmentation. Building upon this work, this letter paper presents an improved data augmentation scheme based on predictor-corrector steps that enforces a user-defined level of accuracy, and shows that the error bound of the augmented samples are independent of the size of the neighborhood used for data augmentation.

description: Massive neutrinos and $f(R)$ modified gravity have degenerate observational signatures that can impact the interpretation of results in galaxy survey experiments, such as cosmological parameter estimations and gravity model tests. Because of this, it is important to investigate astrophysical observables that can break these degeneracies. Cosmic voids are sensitive to both massive neutrinos and modifications of gravity and provide a promising ground for disentangling the above mentioned degeneracies. In order to analyse cosmic voids in the context of non-$Λ$CDM cosmologies, we must first understand how well the current theoretical framework operates in these settings. We performed a suite of simulations with the RAMSES-based N-body code ANUBISIS, including massive neutrinos and $f(R)$ modified gravity both individually and simultaneously. The data from the simulations were compared to models of the void velocity profile and the void-halo cross-correlation function (CCF). This was done both with the real space simulation data as model input and by applying a reconstruction method to the redshift space data. In addition, we ran Markov chain Monte Carlo (MCMC) fits on the data sets to assess the capability of the models to reproduce the fiducial simulation values of $fσ_8(z)$ and the Alcock-Paczynski parameter, $ε$. The void modelling applied performs similarly for all simulated cosmologies, indicating that more accurate models and higher resolution simulations are needed in order to directly observe the effects of massive neutrinos and $f(R)$ modified gravity through studies of the void-galaxy CCF. The MCMC fits show that the choice of void definition plays an important role in the recovery of the correct cosmological parameters, but otherwise, there is no clear distinction between the ability to reproduce $fσ_8$ and $ε$ for the various simulations.

We obtain the Tolman-Oppenheimer-Volkov equations corresponding to this class of theories and show that they recover those of f(R) theories and General Relativity in the appropriate limits. We compute exterior vacuum solutions and comment on the possible expected modifications, as compared to GR, of the interior solutions.

title: APEX (A’ Experiment): The search for a dark photon at Jefferson Lab
Creators: name: Williamson, John Thomas Austin
Publisher: name: University of Glasgow
Year: 2022

description: The A’ Experiment (APEX) in Hall A of Jefferson Lab is a search for a new vector gauge boson, A’. The A’, or dark photon, serves as the mediator of a dark sector, a model for dark matter. Kinetic mixing, characterised by the strength parameter e², between the A’ and the Standard Model photon would allow for its experimental observation. For APEX the A’ production mechanism is dark bremsstrahlung in interactions of an electron beam with a high-Z target, which would be followed by decay to a lepton pair (the case of a visible dark photon). The High Resolution Spectrometers are set-up to record e⁺e⁻ pairs, from which an invariant mass distribution can be obtained. A resonance search is then performed on this invariant mass spectrum, looking for the A’. A test run for APEX was performed in 2010 with a beam energy of 2.260 GeV, which established limits down to e² ≃ 1 x 10⁻⁶ in the mass range 175–250 MeV [1]. This generated wide interest and proved the viability of the experiment. An APEX production run was carried out in 2019, with a beam energy of 2.138 GeV. This thesis presents the analysis and preliminary results from this 2019 run period. Multiple stages of analysis were conducted in order to obtain a final invariant mass spectrum and to optimise the invariant mass resolution. A blinded peak search was performed on 10% of the final invariant mass distribution, to select background parameters without biasing a full search. The blinded peak search did not find any evidence for the A’ in the mass range 130-220 MeV, and established limits down to e² ≃ 6 x 10⁻⁷.

Πιο συγκεκριμένα τα στοιχεία τα οποία εξετάζονται αφορούν δημογραφικές, κοινωνικοοικονομικές μεταβλητές καθώς και μεταβλητές που αναφέρονται στη σωματική υγεία και στα συστήματα ασφάλισης υγείας. Στο 3ο κεφάλαιο περιγράφονται εν συντομία οι μεταβλητές οι οποίες υπάρχουν στη βάση δεδομένων (database) ενώ παράλληλα γίνεται μία πρώτη προσέγγιση περιγραφικής ανάλυσής τους μέσω της μονομεταβλητής ανάλυσης. Στο 4ο κεφάλαιο πραγματοποιούμε τη διμεταβλητή ανάλυση με χρήση μεθόδων περιγραφικής στατιστικής όπως μέτρων συνάφειας, διαγραμμάτων και ελέγχων ανεξαρτησίας, ώστε να εξεταστεί η συσχέτιση των διαφόρων μεταβλητών με τη διαμόρφωση των ποσοστών θνησιμότητας. Στη συνέχεια, στο 5ο κεφάλαιο αναπτύσσονται μοντέλα λογιστικής παλινδρόμησης βάσει των οποίων μελετάται η επίδραση των δημογραφικών, κοινωνικοοικονομικών μεταβλητών, σωματικής υγείας και ιδιωτικής ασφάλισης υγείας στη θνησιμότητα. Συνοψίζοντας, στο 6ο και τελευταίο κεφάλαιο αναφέρονται τα κυριότερα συμπεράσματα που προέκυψαν μέσω της ανάλυσης των διαθέσιμων δεδομένων. Αξίζει να αναφερθεί αρχικά πως επιβεβαιώθηκε η επίδραση των δημογραφικών και κοινωνικοοικονομικών παραγόντων και όσων σχετίζονται με τη σωματική υγεία. Επιπλέον οι παράγοντες που αναφέρονται στη σωματική υγεία εμφανίζονται αρκετά πιο σημαντικοί συγκριτικά με τους κοινωνικοοικονομικούς παράγοντες. Τέλος, ιδιαίτερα σημαντική είναι η διαπίστωση πως η ιδιωτική ασφάλιση υγείας διαδραματίζει καθοριστικό ρόλο στη μείωση της πιθανότητας θανάτου.

description: Over the past decade, infrastructure development has turned from a peripheral phenomenon into a key pillar of cooperation between China and Africa. This study scrutinises the political economy of Chinese infrastructure projects in Africa – both in theoretical and empirical terms. Informed by a critical realist philosophy of science, this research has been characterised by an iterative methodological movement between conceptual abstractions and the concrete cases under scrutiny, viz. Zambia’s road sector and the Tanzania-Zambia Railway Authority (TAZARA). Drawing on David Harvey’s theory of spatio-temporal fixes, the study posits that Africa’s recent infrastructure boom is driven by Chinese overaccumulation. A strategic-relational approach to the structure-agency conundrum is employed to trace African state agency in the unfolding of the Chinese ‘infrastructural fix’ and to assess how African governments are differentially constrained and enabled by their particular structural contexts. With respect to Zambia’s road sector, it is argued that the infrastructural fix has been fostered by the government’s ambitious, debt-financed infrastructure development agenda as well as by ‘not so public’ procurement processes. More recently, Zambia’s shrinking fiscal space has caused a shift in the governance of the ‘fix’ from public debt financing to private project finance, thereby heralding new rounds of accumulation by dispossession. In the case of TAZARA, the Chinese infrastructural fix has not yet materialised because of a changing balance of political forces in Tanzania. President Magufuli’s time in office has been characterised by rigid state interventions vis-à-vis foreign investment, a relative strengthening of legal-rational bureaucratic procedures and the resuscitation of developmentalist policies. This has translated into strategic pragmatism and cautious cost-benefit analyses regarding a Chinese participation in TAZARA. The study concludes that the extent to which Sino-African cooperation in the infrastructure sector affords ‘win-win’ results is largely contingent upon African state actors and their differentially constraining structural contexts.

description: The gravitational-wave (GW) detector data are affected by short-lived instrumental or terrestrial transients, called glitches, which can simulate GW signals. Mitigation of glitches is particularly difficult for algorithms which target generic sources of short-duration GW transients (GWT), and do not rely on GW waveform models to distinguish astrophysical signals from noise, such as Coherent WaveBurst (cWB). This work is part of the long-term effort to mitigate transient noises in cWB, which led to the introduction of specific estimators, and a machine-learning based signal-noise classification algorithm. Here, we propose an autoencoder neural network, integrated into cWB, that learns transient noises morphologies from GW time-series. We test its performance on the glitch family known as blip. The resulting sensitivity to generic GWT and binary black hole mergers significantly improves when tested on LIGO detectors data from the last observation period (O3b). At false alarm rate of one event per 50 years the sensitivity volume increases up to 30% for signal morphologies similar to blip glitches. In perspective, this tool can adapt to classify different transient noise classes that may affect future observing runs, enhancing GWT searches.

title: Conceptualisation, assessment and treatment of Anhedonia in adolescent depression
Creators: name: Watson, Rebecca
Publisher: name: University of Reading
Year: 2021

description: Anhedonia, the loss of interest and/or pleasure in previously enjoyable experiences is a core symptom of Major Depressive Disorder. It is associated with depression severity, relapse and poor treatment outcome. Despite this, little is known about how this symptom is experienced by adolescents. Most current psychological treatments for depression do not target anhedonia and for young people there are no adequate measures of this symptom for use in research or treatment. This thesis aims to explore adolescents’ experiences of anhedonia, to critically evaluate the available anhedonia self-report measures and to develop a self-report measure that can be used by therapists and researchers to develop effective ways to reduce anhedonia in young people. Paper 1 explores adolescents’ experiences of anhedonia. Semi-structured interviews about the experience of anhedonia were conducted with 34 adolescents with a primary diagnosis of depression (n = 12) or elevated depressive symptoms (n = 22). Next self-reported measurements of anhedonia were examined. Paper 2 presents a systematic review and critical evaluation of the psychometric properties of 14 self-report anhedonia scales, which highlights limitations in their psychometric properties and relevance for adolescents. Following on from this, Paper 3 describes the development and validation (n = 2098) of an adolescent specific self-report measure of anhedonia developed based on adolescents’ experiences of anhedonia defined in Paper 1. Lastly, the treatment of adolescent anhedonia was explored in Paper 4. In this qualitative study, adolescents’ (n = 8) experiences of Brief Behavioural Activation (BA) for depression, a treatment development to enhance positive reinforcement and increase engagement in valued activities, were explored with a focus on understanding its impact on anhedonia. Taken together, these findings have implications for understanding, assessing and treating the symptom of anhedonia during adolescence in both clinical and research settings.

description: We report the existence of spiral arms in the recently formed gaseous and dusty disk of the closest giant elliptical, NGC 5128 (Centaurus A), using high resolution 12CO(2-1) observations of the central 3 arcmin (3 kpc) obtained with the Submillimeter Array (SMA). This provides evidence that spiral-like features can develop within ellipticals if enough cold gas exists. We elucidate the distribution and kinematics of the molecular gas in this region with a resolution of 4.4 x 1.9 (80 pc x 40 pc). The spiral arms extend from the circumnuclear gas at a radius of 200 pc to at least 1 kiloparsec. The general properties of the arms are similar to those in spiral galaxies: they are trailing, the width is \sim 500 \pm 200 pc, and the pitch angle is 20 degrees. From independent estimates of the time when the HI-rich galaxy merger occurred, we infer that the formation of spiral arms happened on a time scale of less than \sim10^8 yr. The formation of spiral arms increases the gas density and thus the star formation efficiency in the early stages of the formation of a disk.

description: The variation after projection (VAP) method is expected to be an efficient way of getting the optimized nuclear wave functions, so that they can be as close as possible to the exact shell model ones. However, we found there are two additional problems that may seriously affect the convergence of the VAP iteration. The first problem is, if a randomly selected projected basis state does not mix with a VAP wave function in the VAP calculation, then it is likely that this basis state will never mix with the VAP wave function even after the VAP iteration converges, which means such selected projected basis state is useless. The other problem is the poor orthonormality among the projected basis states that seriously affect the accuracy of the calculated VAP wave function. In the present work, solutions for these two problems are proposed and some examples are presented to test the validity. It turns out that, with the present solutions, the most important projected basis states can be reliably obtained and the fully optimized VAP wave functions can be accurately and efficiently calculated.

description: We present a time-dependent approach to the one-zone hadronic model in the case where the photon spectrum is produced by ultrarelativistic protons interacting with soft photons that are produced from protons and low magnetic fields. Assuming that protons are injected at a certain rate in a homogeneous spherical volume containing a magnetic field, the evolution of the system can be described by five coupled kinetic equations, for protons, electrons, photons, neutrons, and neutrinos. Photopair and photopion interactions are modelled using the results of Monte-Carlo simulations and, in particular from the SOPHIA code for the latter. The coupling of energy losses and injection introduces a self-consistency in our approach and allows the study of the comparative relevancy of processes at various conditions, the efficiency of the conversion of proton luminosity to radiation, the resulting neutrino spectra, and the effects of time variability on proton injection, among other topics. We present some characteristic examples of the temporal behaviour of the system and show that this can be very different from the one exhibited by leptonic models. Furthermore, we argue that, contrary to the wide-held belief, there are parameter regimes where the hadronic models can become quite efficient. However, to keep the free parameters at a minimum and facilitate an in-depth study of the system, we have only concentrated on the case where protons are injected; i.e., we did not consider the effects of a co-accelerated leptonic component.

Robust phase metrology with hybrid quantum interferometers against particle losses

description: Entanglement is an important quantum resource to achieve high sensitive quantum metrology. However, the rapid decoherence of quantum entangled states, due to the unavoidable environment noise, result in practically the unwanted sharp drop of the measurement sensitivity. To overcome such a difficulty, here we propose a spin-oscillator hybrid quantum interferometer to achieve the desirable precise estimation of the parameter encoded in the vibrations of the oscillator. Differing from the conventional two-mode quantum interferometers input by the two-mode NOON state or entangled coherent states (ECS), whose achievable sensitivities are strongly limited by the decoherence of the entangled vibrational states, we demonstrate that the present interferometer, input by a spin-dependent two-mode entangled state, possesses a manifest advantage, i.e., the measurement sensitivity of the estimated parameter is not influenced by the decoherence from the spin-oscillator entanglement. This is because that, by applying a spin-oscillator disentangled operation, the information of the estimated parameter encoded originally in the vibrational degrees can be effectively transferred into the spin degree and then can be sensitively estimated by the precise spin-state population measurements. As consequence, the proposed hybrid quantum interferometer possesses a manifest robustness against the particle losses of the vibrational modes. Interestingly, the achieved phase measurement sensitivity can still surpass the SQL obviously, even if relatively large number of particle loss occurs in one of the two modes. The potential application of the proposed spin-oscillator hybrid quantum interferometer is also discussed.

description: Given a unipotent bundle of smooth manifolds we construct its secondary transfer map and show that this map determines the higher smooth torsion of the bundle. This approach to higher torsion provides a new perspective on some of its properties. In particular it yields in a natural way a formula for torsion of a composition of two bundles.

description: Gaussian quantum steering is a type of quantum correlation in which two entangled states exhibit asymmetry. We present an efficient theoretical scheme for controlling quantum steering and enhancing entanglement in a Laguerre-Gaussian (LG) rotating cavity optomechanical system with an optical parametric amplifier (OPA) driven by coherent light. The numerical simulation results show that manipulating system parameters such as parametric gain $χ$, parametric phase $θ$, and rotating mirror frequency, among others, significantly improves mirror-mirror and mirror-cavity entanglement. In addition to bipartite entanglement, we achieve mirror-cavity-mirror tripartite entanglement. Another intriguing discovery is the control of quantum steering, for which we obtained several results by investigating it for various system parameters. We show that the steering directivity is primarily determined by the frequency of two rotating mirrors. Furthermore, for two rotating mirrors, quantum steering is found to be asymmetric both one-way and two-way. As a result, we can assert that the current proposal may help in the understanding of non-local correlations and entanglement verification tasks.

title: Αξιολόγηση πιστωτικού κινδύνου επιχειρήσεων μέσω λογιστικών στοιχείων και υποδειγμάτων αποτίμησης δικαιωμάτων προαίρεσης

description: Η εκτίμηση του πιστωτικού κινδύνου αποτελεί σημαντικό πρόβλημα στην περιοχή της διαχείρισης χρηματοοικονομικών κινδύνων. Είναι ένα θέμα που αφορά τόσο τα χρηματοπιστωτικά ιδρύματα, όσο και τις επιχειρήσεις, ιδιαίτερα σε περιόδους οικονομικής ύφεσης. Υπάρχει πληθώρα μεθόδων και προσεγγίσεων οι οποίες έχουν αναπτυχθεί κατά τα τελευταία χρόνια για την δημιουργία μοντέλων αξιολόγησης και μέτρησης του πιστωτικού κινδύνου. Ο σκοπός της διατριβής είναι διττός. Αρχικά, πραγματοποιείται μια εμπειρική σύγκριση διαφορετικών δημοφιλών τεχνικών (λογιστική παλινδρόμηση, μηχανές διανυσμάτων υποστήριξης και της πολυκριτήριας μεθόδου UTADIS) με χρήση δεδομένων που προέρχονται από Ελληνικές εμπορικές επιχειρήσεις. Τα αποτελέσματα δείχνουν ότι ακόμα και με ένα μικρό αριθμό ασυνεπών επιχειρήσεων, το οποίο δημιουργεί μια ανισορροπία στο δείγμα, τα αποτελέσματα όλων των μεθόδων είναι ικανοποιητικά. Ο δεύτερος στόχος, έχει να κάνει με την δημιουργία ενός μοντέλου αξιολόγησης του πιστωτικού κινδύνου, με χρήση τεχνικών μηχανικής μάθησης και πολυκριτήριας ανάλυσης, το οποίο θα συνδυάζει λογιστικά στοιχεία με την προσέγγιση του μοντέλου αγοράς των Black, Scholes και Merton και θα μπορεί να χρησιμοποιηθεί σε μη-εισηγμένες επιχειρήσεις. Το μοντέλο χρησιμοποιεί στοιχεία εισηγμένων ελληνικών επιχειρήσεων, αλλά τα αποτελέσματα δείχνουν ότι η προβλεπτική ικανότητά του είναι παρεμφερής με μοντέλα που χρησιμοποιούν ιστορικά δεδομένα ασυνέπειας τα οποία δεν είναι διαθέσιμα στο ευρύ κοινό.
description: Credit risk evaluation is a very challenging and important problem in the domain of financial risk management. It is an important issue for both financial institutions and companies, especially in periods of economic recession. There are many different approaches and methods which have been developed over the years for constructing credit risk assessment rating systems. The aim of this thesis is twofold. First, an empirical comparison of different popular techniques (logistic regression, support vector machines, and the UTADIS multicriteria method) using a data set of Greek companies from the commercial sector is executed. The results show that even with a considerable imbalanced data set with a small number of defaults, all methods provide good results. The second goal is to create a credit risk rating model, using a machine learning methodology and a multicriteria method that combines accounting data with the option-based approach of Black, Scholes, and Merton and the extension to non-listed firms. The model is built on data for companies listed in the Greek stock exchange, but it is also shown that the predictive performance is similar to accounting-based models developed using (non- publicly available) historical default data.

description: It has been known for some time that 2-loop renormalization group (RG) equations of a dimensionless parameter can be solved in a closed form in terms of the Lambert W function. We apply the method to a generic theory with a Gaussian fixed point to construct RG invariant physical parameters such as a coupling constant and a physical squared mass. As a further application, we speculate a possible exact effective potential for the O(N) linear sigma model in four dimensions.
