description: Observations by in-situ transmission electron microscopy (TEM) reveal the changes in domains morphology in 0.885(Bi1/2Na1/2)TiO3-0.05(Bi1/2K1/2)TiO3-0.015(Bi1/2Li1/2)TiO3-0.05BaTiO3 ceramics. Evolution of the macroscopic ferroelectric domains has been observed at 25 oC to 180 oC. The ferroelectric domains and their walls reduce progressively with increasing temperature. In the selected-area electron diffraction (SAED) patterns the crystallographic evidence of antiferroelectric domain is not found over the temperature range, which provides the evidence that the ferroelectric-antiferroelectric transition does not occur in the ceramic. The temperature-dependent forbidden 3/2 1/2 0 and superstructure 3/2 1/2 1/2 reflections indicate the presence of an in-phase and anti-phase octahedral tilting in the ceramic, respectively. Dark-field TEM images show that the size of the octahedral tilted domains is smaller than 30 nm across and these domains are uniformly distributed in the grains. The influence of the localized octahedral titling on the stability of ferroelectric domains and the temperature-dependent properties is discussed in this paper.

title: The autonomy of private instrumental teachers: its effect on valid knowledge construction, curriculum design, and quality of teaching and learning
Creators: name: Barton, D. C. M.
Publisher: name: Royal College of Music
Year: 2020

description: This research aims to open doors into the world of private instrumental teaching. As well as examining the varied nature of the profession and the work private teachers undertake, it seeks to uncover more about who private teachers are and the way they view that work which they carry out. Notably, in view of their position outside of institutional frameworks, the research seeks to understand the factors which influence what and how private teachers teach, and in particular, the way they perceive pupil input. Despite the widespread and important role private instrumental teachers play within the music education sector, they inhabit a position which has often been described as isolated; their work taking place behind closed doors. Whilst the nature of one-to-one instrumental teaching has been examined in a variety of contexts, notably higher education, private teachers occupy an almost unique position, operating outside of institutional control. Private teachers have previously been seen as difficult to reach, and researchers have voiced concerns that research into private teaching may be seen as an invasion of teachers’ privacy. From a social constructivist position, and situated within an interpretivist paradigm, I conducted three unstructured interviews with private teachers. These provided the foundation for research which was then expanded to include an online survey of private teachers which received 486 responses. Using an iterative approach, ensuring constant dialogue between data gathered and existing literature, interview and survey data were thematically coded and analysed, and key themes identified. Whilst private teachers were committed to the work they undertook, responses suggest they were often uncritical in their practice. The dataset indicates an emerging dichotomy between the autonomy private teachers possess and their ability to manage that freedom, leading to communities of practice which do not function at as high a level as they might. This research makes a valuable contribution to an under-researched area of music education, highlighting a number of implications for practice. At a time when state-funded music provision is under threat, it is essential that key stakeholders better-understand the role private teachers play as part of the wider music education profession.

title: Acoustic Sensing for Assistive Living: Investigating ML Models to Address Privacy and Data Collection Challenges
Creators: name: Nicolaou, Pavlos
Publisher: name: University of Kent
Year: 2025

description: Assistive living technologies have advanced significantly, utilising wearable sensors and other smart devices. While wearables are effective in monitoring human activity, they may become impractical when the elderly are resistant to them. In contrast, audio sensing can passively monitor daily routines without the burden of managing wearable devices. This research is divided into three parts: the first focuses on an unsupervised application of acoustic sensing, the second distinguishes data collection and application challenges in an acoustic environment, and the third presents a proposed pipeline that can solve privacy concerns regarding speech in an acoustic environment. Audio as a modality is rich with contextual information and can be very useful in sensing activities in a home environment. Because of the nature of an audio-sensing environment, there are some restrictions we have to keep in mind in terms of data collection and privacy. Firstly, having a large amount of labelled data is not possible. Therefore, this thesis's first part focuses on an unsupervised approach to detect changes in daily routine in an acoustic environment with a 14% improvement in the F1 score compared to the previous baseline. The second part of our research sets the challenges of any acoustic home environment regarding data collection and speech privacy, showcasing the solution deployed in the industry. Finalising this thesis with the creation of a three-stage methodology on developing a privacy pervasive system, which is a system that ensures privacy is maintained at all stages of data processing, regarding speech audio data and the possibility of having a passive audio sensing system that discards all speech data and then having the possibility to apply any audio sensing techniques without compromising privacy. The proposed methodology achieved this by eliminating all private conversations from the acoustic signal, resulting in a minor reduction of 2-13% in the F1 score for acoustic activity detection across various datasets.

Flavor Structure of the Three Site Higgsless Model

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We study the flavor structure in the three site Higgsless model. In this model, the gauge bosons and fermions have heavy partners, coming from the Kaluza-Klein excitation in the dimensional deconstruction picture. The yukawa couplings are introduced in a way to minimize the flavor chaning neutral current in the light sector at the tree level. Due to the flavor mixing between the light and the heavy partner fields, new effects on FCNC's appear at one-loop level. As an example of such FCNC processes, we calculate the contribution to the b -> s gamma amplitude in the three site Higgsless model. Interestingly, heavy particles which exist in the three site Higgsless model do not completely decouple in the heavy-mass limit. One-loop level b -> s gamma amplitude is calculated by considering all possible combinations of particles in the loop, then it is compared to the experiment. The result shows that the central value of the B -> X_s gamma branching ratio in the three site Higgsless model takes closer value to its experimental central value as one takes the larger value of a free parameter, \varepsilon_{tR}, within a range allowed by the precision electroweak measurement.

description: Let $h>w>0$ be two fixed integers. Let $\orH$ be a random hypergraph whose hyperedges are all of cardinality $h$. To {\em $w$-orient} a hyperedge, we assign exactly $w$ of its vertices positive signs with respect to the hyperedge, and the rest negative. A $(w,k)$-orientation of $\orH$ consists of a $w$-orientation of all hyperedges of $\orH$, such that each vertex receives at most $k$ positive signs from its incident hyperedges. When $k$ is large enough, we determine the threshold of the existence of a $(w,k)$-orientation of a random hypergraph. The $(w,k)$-orientation of hypergraphs is strongly related to a general version of the off-line load balancing problem. The graph case, when $h=2$ and $w=1$, was solved recently by Cain, Sanders and Wormald and independently by Fernholz and Ramachandran, which settled a conjecture of Karp and Saks.

description: The requirement of electroweak naturalness in simple supersymmetric models motivates the existence of a cluster of four light higgsinos with mass $100 - 300$ GeV, the lighter the better. While such light compressed spectra may be challenging to observe at the LHC, future $e^+e^-$ colliders with $\sqrt{s} > 2$m(higgsino) would serve as both a SUSY discovery machine and a precision microscope.We study signatures of higgsino pair production at the ILC based on full, Geant4-based simulation of the ILD detector concept. We examine several benchmark scenarios that may or may not be accessible to HL-LHC searches, with mass differences between the higgsino states between 4 and 20 GeV. Assuming $\sqrt{s}\geq$ 500 GeV and $1000$ fb$^{-1}$ of integrated luminosity, the individual higgsino masses can be measured to $1 - 2\%$ precision in case of the larger mass differences, and at the level of 5$\%$ for the smallest mass difference case. The higgsino mass splittings are sensitive to the electroweak gaugino masses and can allow extraction of gaugino masses to $3 - 20\%$ (depending on the model). Extrapolation of gaugino masses via renormalization group running can test the hypothesis of gaugino mass unification. We also examine a case with natural generalized mirage mediation where the unification of gaugino masses at an intermediate scale apparently gives rise to a natural SUSY spectrum somewhat beyond the reach of the HL-LHC.

Influence of turbidity and aeration on the albedo of mountain streams
Creators: name: McMahon, Alexander D.
Publisher: name: University of British Columbia
Year: 2016

description: Stream surface albedo plays a key role in the energy balance of rivers and streams that are exposed to direct solar radiation. Most physically based models assume that stream albedo lies between 0.03 and 0.10, based primarily on measurements from low-gradient streams with low suspended sediment concentrations. Albedo should depend upon solar elevation angle, suspended sediment, aeration, and fraction of direct vs diffuse radiation. However, there is no model available for predicting the dependence of albedo on these factors. This study quantified the dependence of albedo of mountain streams on the controlling factors in order to improve the representation of albedo in energy balance studies. Proxy measures for albedo using digital camera imagery were also developed and assessed. Stream surface albedo was measured at nine sites with a variety of gradients and suspended sediment characteristics in the southern Coast Mountains of British Columbia, Canada. As expected, albedo of low-gradient, non-whitewater (flatwater) streams increased with solar zenith angle, suspended sediment concentration, and proportion of diff use to direct solar radiation, ranging between 0.025 during cloudy periods in clear water to 0.25 for turbid water at zenith angles of less than 20 degrees. Albedo varied with discharge in steep reaches or at channel steps and cascades where flow was visibly aerated, with a range of 0.09 to 0.33. In clear weather, albedo exhibited notable diurnal variability at flatwater sampling sites. For example, during late summer, surface albedo typically fluctuated between 0.08 and 0.15 on a diurnal basis at a flatwater site on the highly turbid, glacier-fed Lillooet River. Physically based representations of albedo should be incorporated into energy balance models in order to improve predictions of stream temperature, especially for future scenarios.
EVALUATION OF LEFT VENTRICULAR AND ATRIAL-APPENDAGE FUNCTION IN NORMAL AND ISCHEMIC MOUSE MODELS BY CARDIAC IMAGING TECHNIQUES: A PHARMACOLOGICAL VALIDATION
Creators: name: CASTIGLIONI, LAURA
Publisher: name: Universit� degli Studi di Milano

description: Despite progress in diagnosis and treatment lead to a significant reduction of the rate of death attributable to cardiovascular disease (CVD), many efforts must to be done to modify the pathological process and enhance protection. Thus the development of new technologies for diagnosis and novel therapeutic agents is fundamental for clinicians and researcher.
In the last decade, murine model had become a useful tool to study CVDs mechanism and to test new pharmacological treatments.
Noninvasive imaging technique, specific for laboratory animals, provide the opportunity to image longitudinally the same animal, investigating the follow-up of pathologies and assessing the effect of pharmacological treatments.
Aims of this work are to set up an animal model of myocardial infarction (MI) and cardiac imaging (cardiac magnetic resonance imaging and echocardiography) of left ventricle (LV), left atrium (LA) and appendage (LAA) in healthy mice, and then evaluate the global and regional functional-structural changes and remodeling occurring on LV, LA and LAA after MI, with or without pharmacological treatment. The in vivo imaging data were supported by morphological, histological and gene expression analysis.
Results from this study described the regional area changes occurring on LV after MI with a progressive loss of contractility also in remote non-infarcted tissue; the presence of only three pulmonary veins entering LA and the presence of the large LAA which, working together with LA, plays an important role in LV filling. After MI not only LV but also LA and LAA remodel in order to maintain, with their enlargement, LV stroke volume. The pharmacological treatment with valsartan, a selective inhibitor of AT1 receptor of Ang II, influenced LV remodeling by reducing LV enlargement, infarct size, ECM gene expression (in particular collagen VIII, fibulin-2 involved in fibrosis and hypertrophy), preserving LV SV without affecting LAA and LA increase in dimension.

description: The mobility of graphene transferred on a SiO2/Si substrate is limited to ~10,000 cm2/Vs. Without understanding the graphene/SiO2 interaction, it is difficult to improve the electrical transport properties. Although surface structures on SiO2 such as silanol and siloxane groups are recognized, the relation between the surface treatment of SiO2 and graphene characteristics has not yet been elucidated. This paper discusses the electrical transport properties of graphene on specific surface structures of SiO2 prepared by O2-plasma treatments and reoxidization.

Ensembles based on Random Projection for gene expression data analysis
Creators: name: FOLGIERI, RAFFAELLA
Publisher: name: Universit� degli Studi di Milano
Year: 2008

description: In this work we focused on methods to solve classification problems characterized
by high dimensionality and low cardinality data. These features are relevant
in bio-molecular data analysis and particularly in class prediction whith microarray
data.
Many methods have been proposed to approach this problem, characterized by
the so called curse of dimensionality (term introduced by Richard Bellman (9)).
Among them, gene selection methods, principal and independent component analysis,
kernel methods.
In this work we propose and we experimentally analyze two ensemble methods
based on two randomized techniques for data compression: Random Subspaces
and Random Projections. While Random Subspaces, originally proposed by T.
K. Ho, is a technique related to feature subsampling, Random Projections is a feature
extraction technique motivated by the Johnson-Lindenstrauss theory about
distance preserving random projections.
The randomness underlying the proposed approach leads to diverse sets of extracted
features corresponding to low dimensional subspaces with low metric distortion
and approximate preservation of the expected loss of the trained base
classifiers.
In the first part of the work we justify our approach with two theoretical results.
The first regards unsupervised learning: we prove that a clustering algorithm minimizing
the objective (quadratic) function provides a -closed solution if applied
to compressed data according to Johnson-Lindenstrauss theory.
The second one is related to supervised learning: we prove that Polynomials kernels
are approximatively preserved by Random Projections, up to a degradation proportional to the square of the degree of the polynomial.
In the second part of the work, we propose ensemble algorithms based on Random
Subspaces and Random Projections, and we experimentally compare them
with single SVM and other state-of-the-art ensemble methods, using three gene
expression data set: Colon, Leukemia and DLBL-FL - i.e. Diffuse Large B-cell
and Follicular Lymphoma. The obtained results confirm the effectiveness of the
proposed approach.
Moreover, we observed a certain performance degradation of Random Projection
methods when the base learners are SVMs with polynomial kernel of high degree.

description: The design of modern instruments does not only imply thorough studies of instrumental effects but also a good understanding of the scientific analysis planned for the data. We investigate the reliability of Milne-Eddington (ME) inversions of high-resolution magnetograph measurements such as those to be obtained with the Imaging Magnetograph eXperiment (IMaX) aboard the Sunrise balloon. We also provide arguments to choose either Fe I 525.02 or 525.06 nm as the most suitable line for IMaX. We reproduce an IMaX observation using magnetoconvection simulations of the quiet Sun and synthesizing the four Stokes profiles emerging from them. The profiles are degraded by spatial and spectral resolution, noise, and limited wavelength sampling, just as real IMaX measurements. We invert these data and estimate the uncertainties in the retrieved physical parameters caused by the ME approximation and the spectral sampling.It is possible to infer the magnetic field strength, inclination, azimuth, and line-of-sight velocity from standard IMaX measurements (4 Stokes parameters, 5 wavelength points, and a signal-to-noise ratio of 1000) applying ME inversions to any of the Fe I lines at 525 nm. We also find that telescope diffraction has important effects on the spectra coming from very high resolution observations of inhomogeneous atmospheres. Diffration reduces the amplitude of the polarization signals and changes the asymmetry of the Stokes profiles. The two Fe I lines at 525 nm meet the scientific requirements of IMaX, but Fe I 525.02 nm is to be preferred because it leads to smaller uncertainties in the retrieved parameters and offers a better detectability of the weakest (linear) polarization signals prevailing in the quiet Sun.

description: Several environmental and endogenous stimuli activate plant signal transduction pathways through transient increases in cytosolic free calcium concentrations ([Ca2+]cyt). Strong evidence indicates that plant response specificity is triggered by the amplitude, shape, frequency and localization of these stimulus-induced Ca2+ oscillations. Due to their role in Ca2+ efflux from the cytosol, plant auto-inhibited Ca2+-ATPases (ACAs) are involved in restoring the cytosolic basal concentration of Ca2+ after its rise due to stimulus perception, therefore affecting the specificity of plant response to different stimuli. Ten ACA isoforms are present in Arabidopsis thaliana, which are divided into four clusters based on gene structure and sequence homology. Cluster I, II and IV ACAs share a common mechanism of regulation based on a N-terminal auto-inhibitory domain whose action is suppressed by the interaction with the Ca2+-sensor protein calmodulin (CaM). Cluster III isoforms (ACA12 and ACA13) compared to the other ACAs, are almost unknown and show unique features at sequence and expression levels: in particular ACA12 and ACA13 show divergences in residues involved in CaM binding and regulation while the expression levels, normally very low, are increased upon exposure to pathogens or UV stresses.
By confocal microscopy, a GFP-tagged ACA12 (expressed in Arabidopsis plants) was localized at the plasma membrane (PM). ACA12 was then expressed in Saccharomyces cerevisiae strain K616, which lacks endogenous Ca2+ pumps. Our results reveal that ACA12 allows the grow of K616 in a Ca2+-depleted medium, therefore indicating that it is a functional and deregulated Ca2+ transporter. Yeast-expressed ACA12 was then purified by CaM-affinity chromatography and its activity was tested in vitro in order to study its biochemical properties. Biochemical assays results show that ACA12 is a functional Ca2+-ATPase. Moreover, as expected, its activity is not regulated by CaM. Finally, in order to try to explain ACA12 deregulated behaviour, single point mutants of ACA12 were generated and tested for K616 phenotype complementation.
Taken together our results show that ACA12 has unique biochemical features suggesting for it a distinctive physiological role within the ACA family. In particular ACA12 may be involved in Ca2+-dependent signaling pathways in response to plant specific stresses such as pathogens and UV.

description: Turbulent wall-bounded flows are dominated by the structure and dynamics of coherent motions. Therefore, in order to understand the mechanics of turbulence, it is essential to understand how coherent structures are generated, evolve and dissipate. This thesis has two parts: firstly a digital holography-based three-component - three-dimensional velocimetry method is developed and assessed to enable the measurement of turbulent flows; secondly, since due to COVID-19 restrictions this methodology could not be employed to study wall-bounded flows, high-resolution 2-component - 2-dimensional velocity measurements of a high Reynolds number turbulent boundary layer flow is used to analyse and reveal how coherent structures affect the viscous drag exerted by the fluid on the wall.

description: We present a technique to estimate the inhomogeneities of magnetic loss across the section of ferrite cores under ac excitation. The technique is based on two distinct calorimetric methods that we presented elsewhere. Both methods are based on the measurement of the rate of increase of the sample temperature under adiabatic condition. The temperature ramp is recorded either measuring the sample bulk resistivity or using a platinum probe pasted on the sample surface. As an example we apply the procedure to an industrial sample of Mn-Zn ferrite under controlled sinusoidal excitation with a peak induction of 50 mT in the range between 100 kHz and 2 MHz. The results are discussed by comparison with simulations of the dissipation field profile through the sample, calculated using a finite element method (FEM) code.

description: The term ?optoelectronic devices? is by now used for devices in which both electrons and photons are essential for their operation, as a natural evolution from the definitions of electronic devices that involved only electrons and holes in their operation and of photonic devices that involved only photons in their operation. One of the new lighting technologies which emerged within the past two decades and has the potential of becoming more energy-efficient then the existing light sources, is the Solid State Lighting technology of Organic Light Emitting Diodes (OLEDs). In general, the basic OLED structure consists of a stack of fluorescent organic layers sandwiched between a transparent conducting anode and metallic cathode. When an appropriate current is applied to the device, holes are injected from the anode and electrons from the cathode; some of the recombination events between the holes and electrons result in electroluminescence (EL). The first part of this PhD Thesis surveyed different aspect in OLED technology that are currently under debate. In particular chapter 2 is devoted to the study, preparation and optimization of thin films between the organic hole transport layer and the anode surface while chapter 3 deals with the synthesis of trifluorene compound, with methoxy substituents, as possible UV-blue emitter. The second part of this PhD work is dedicated to the synthesis and study of new materials with interesting emissive and second order NLO properties. In particular pyrene based chromophores are investigated in chapter 4, while chapter 5 deals with the synthesis of organic-inorganic perylene-POSS hybrids with enhanced emissive properties.

description: We report the pressure dependences of the superconducting transition temperature (T_c) in several perovskite-type Fe-based superconductors through the resistivity measurements up to ~4 GPa. In Ca_4(Mg,Ti)_3Fe_2As_2O_y with the highest T_c of 47 K in the present study, the T_c keeps almost constant up to ~1 GPa, and starts to decrease above it. From the comparison among several systems, we obtained a tendency that low T_c with the longer a-axis length at ambient pressure increases under pressure, but high T_c with the shorter a-axis length at ambient pressure hardly increases. We also report the ^75As-NMR results on Sr_2VFeAsO_3. NMR spectrum suggests that the magnetic ordering occurs at low temperatures accompanied by some inhomogeneity. In the superconducting state, we confirmed the anomaly by the occurrence of superconductivity in the nuclear spin lattice relaxation rate 1/T_1, but the spin fluctuations unrelated with the superconductivity are dominant. It is conjectured that the localized V-3d moments are magnetically ordered and their electrons do not contribute largely to the Fermi surface and the superconductivity in Sr_2VFeAsO_3.

description: Abstract
Liver transient elastography, Fibroscan, in measuring the stiffness, is a reliable, noninvasive predictor of disease severity in chronic liver disease of viral aetiology. Owing to the relationships among severity of chronic liver disease , portal hypertension and spleen involvement, the assessment of splenic stiffness may have an added value in staging chronic liver disease . Of 132 chronic liver disease patients of viral aetiology, (CLD) 48 with myeloproliferative disorders (MD) and 64 healthy volunteers (HV), were concurrently investigated by both liver and spleen stiffness. Liver disease severity was staged by liver biopsy (score Metavir) taken concurrently with Fibroscan examination and upper gastrointestinal tract endoscopy for gastro-oesophageal varices. The spleen Fibroscan inter-observer agreement was analysed by an intra-class correlation coefficient (ICC); the liver and spleen transient elastography accuracy was evaluated by receiver operating characteristic (ROC) curve analysis. Spleen transient elastography failed in 22 CLD (16.6%), 12 (25%) MD and 12 (18%) HV. In the three groups, the ICC was 0.89 (0.84-0.92), 0.90 (0.85-0.94) and 0.86(0.80-0.91), respectively. In the CLD group, liver transient elastography and spleen transient elastography independently predicted significant fibrosis (OR 5.2 and 4.6) and cirrhosis (OR 7.8 and 9.1), but both transient elastographies were independent from liver necroinflammation and steatosis. The NPV of spleen transient elastography for gastro-oesophageal varices was 100% using a 48 kPa cut-off. Spleen stiffness can be assessed using transient elastography, its value increasing as the liver disease progresses.In liver cirrhosis patients spleen stiffness can predict the presence, but not the grade of esophageal varices, which can be better predicted if both spleen and liver stiffness measurements are used.

Subjects: R&I landscape, mapping of territorial R&I, RRI

description: This document is the main outcome (Deliverable 2.1) of task 2.1 Developing of mapping tools, and features four major chapters. The introductory chapter presents the theoretical framework that underlies the mapping process, and explains the significance of Work Package 2 within TeRRItoria’s work plan. The second chapter explains the details of and the approach to task 2.2 of the project, which focuses on the mapping of the territorial milieux. It provides a clear explanation of the type of mapping process employed by the project, its stages, the process and types of information to be collected, and further provides the details about connecting the produced maps to the design and implementation of the territorial experiments. The third chapter, in turn, focuses on task 2.3, which has a different scope and focus, and aims at producing state-of-the-art analyses of the current implementations of smart specialisation strategies in each of the territories (mapping the territorial R&I ecosystems). Both tasks complement each other and will inform the co-creation process in the design of the territorial experiments.

description: Teleportation is a basic primitive for quantum communication and quantum computing. We address the problem of continuous-variable (unconditional and conditional) teleportation of a pure single-photon state and a mixed attenuated single-photon state generally in a nonunity gain regime. Our figure of merit is the maximum of negativity of the Wigner function that witnesses highly non-classical feature of the teleported state. We find that negativity of the Wigner function of the single-photon state can be {\em unconditionally} teleported for arbitrarily weak squeezed state used to create the entangled state shared in the teleportation. In contrast, for the attenuated single-photon state there is a strict threshold squeezing one has to surpass in order to successfully teleport the negativity of its Wigner function. The {\em conditional} teleportation allows to approach perfect transmission of the single photon for an arbitrarily low squeezing at a cost of a success rate. On the other hand, for the attenuated single photon conditional teleportation cannot overcome the squeezing threshold of the unconditional teleportation and it approaches negativity of the input state only if the squeezing simultaneously increases. However, as soon as the threshold squeezing is surpassed the conditional teleportation still pronouncedly outperforms the unconditional one. The main consequences for quantum communication and quantum computing with continuous variables are discussed.
