description: In astrophysics, we often aim to estimate one or more parameters for each member object in a population and study the distribution of the fitted parameters across the population. In this paper, we develop novel methods that allow us to take advantage of existing software designed for such case-by-case analyses to simultaneously fit parameters of both the individual objects and the parameters that quantify their distribution across the population. Our methods are based on Bayesian hierarchical modelling which is known to produce parameter estimators for the individual objects that are on average closer to their true values than estimators based on case-by-case analyses. We verify this in the context of estimating ages of Galactic halo white dwarfs (WDs) via a series of simulation studies. Finally, we deploy our new techniques on optical and near-infrared photometry of ten candidate halo WDs to obtain estimates of their ages along with an estimate of the mean age of Galactic halo WDs of [11.25, 12.96] Gyr. Although this sample is small, our technique lays the ground work for large-scale studies using data from the Gaia mission.

Convex-split and hypothesis testing approach to one-shot quantum measurement compression and randomness extraction

description: We consider the problem of quantum measurement compression with side information in the one-shot setting with shared randomness. In this problem, Alice shares a pure state with Reference and Bob and she performs a measurement on her registers. She wishes to communicate the outcome of this measurement to Bob using shared randomness and classical communication, in such a way that the outcome that Bob receives is correctly correlated with Reference and Bob's own registers. Our goal is to simultaneously minimize the classical communication and randomness cost. We provide a protocol based on convex-split and position based decoding with its communication upper bounded in terms of smooth max and hypothesis testing relative entropies. We also study the randomness cost of our protocol in both one-shot and asymptotic and i.i.d. setting. By generalizing the convex-split technique to incorporate pair-wise independent random variables, we show that our one shot protocol requires small number of bits of shared randomness. This allows us to construct a new protocol in the asymptotic and i.i.d. setting, which is optimal in both the number of bits of communication and the number of bits of shared randomness required. We construct a new protocol for the task of strong randomness extraction in the presence of quantum side information. Our protocol achieves error guarantee in terms of relative entropy (as opposed to trace distance) and extracts close to optimal number of uniform bits. As an application, we provide new achievability result for the task of quantum measurement compression without feedback, in which Alice does not need to know the outcome of the measurement. This leads to the optimal number of bits communicated and number of bits of shared randomness required, for this task in the asymptotic and i.i.d. setting.

description: Many geophysical and astrophysical phenomena are driven by turbulent fluid dynamics, containing behaviors separated by tens of orders of magnitude in scale. While direct simulations have made large strides toward understanding geophysical systems, such models still inhabit modest ranges of the governing parameters that are difficult to extrapolate to planetary settings. The canonical problem of rotating Rayleigh-Bénard convection provides an alternate approach - isolating the fundamental physics in a reduced setting. Theoretical studies and asymptotically-reduced simulations in rotating convection have unveiled a variety of flow behaviors likely relevant to natural systems, but still inaccessible to direct simulation. In lieu of this, several new large-scale rotating convection devices have been designed to characterize such behaviors. It is essential to predict how this potential influx of new data will mesh with existing results. Surprisingly, a coherent framework of predictions for extreme rotating convection has not yet been elucidated. In this study, we combine asymptotic predictions, laboratory and numerical results, and experimental constraints to build a heuristic framework for cross-comparison between a broad range of rotating convection studies. We categorize the diverse field of existing predictions in the context of asymptotic flow regimes. We then consider the physical constraints that determine the points of intersection between flow behavior predictions and experimental accessibility. Applying this framework to several upcoming devices demonstrates that laboratory studies may soon be able to characterize geophysically-relevant flow regimes. These new data may transform our understanding of geophysical and astrophysical turbulence, and the conceptual framework developed herein should provide the theoretical infrastructure needed for meaningful discussion of these results.

description: As part of an adoption funding programme supported by the EU and building on experience gained through the GÉANT-led OCRE project, the EOSC Future project allotted a total of €4.8 million across three calls, aimed at bridging the gap between commercial service providers and researchers through the EOSC ecosystem. Specifically, the first call in the series awarded five projects for making commercial services more accessible to Research & Education communities via the EOSC Marketplace, to digital service aggregators (e.g. non-profit entities, NRENs, RIs and e-Infrastructures, HPC centres, etc.) teaming up with OCRE cloud service providers. The service is being offered to a wide range of research communities supported by GWDG, with particular emphasis on the Life Sciences community with its often stringent data security and regulatory compliance requirements. Within this community, there are already two prominent use cases that have emerged as flagships. Furthermore, use cases from the astronomy community are being evaluated for deployment on the platform, and there is an expectation that additional communities will embrace this infrastructure in the future, given its broad applicability and appeal.

description: Ethereum smart contracts are immutable to change, which makes them much harder to be maintained compared to traditional programs. This thesis aims to help developers maintain smart contracts developed by Solidity on Ethereum. We first conducted an empirical study to investigate what kinds of maintenance issues will smart contract developers encounter, and how do developers maintain smart contracts? Then, we introduce two methods that use online posts and historical destructed smart contracts to find new smart contract defects. Finally, we proposed DefectChecker, a symbolic execution-based tool to detect the defined contract defects.
On the canonical structure of general relativity with a limiting curvature and its relation to loop quantum gravity

description: Chamseddine and Mukhanov recently proposed a modified version of general relativity that implements the idea of a limiting curvature. In the spatially flat, homogeneous, and isotropic sector, their theory turns out to agree with the effective dynamics of the simplest version of loop quantum gravity if one identifies their limiting curvature with a multiple of the Planck curvature. At the same time, it extends to full general relativity without any symmetry assumptions and thus provides an ideal toy model for full loop quantum gravity in the form of a generally covariant effective action known to all orders. In this paper, we study the canonical structure of this theory and point out some interesting lessons for loop quantum gravity. We also highlight in detail how the two theories are connected in the spatially flat, homogeneous, and isotropic sector.

description: This investigation was started with the intention of determining whether the secretion of haemolysins by Staphylococcus aureus took place in accordance with the signal hypothesis of Blobel and Dobberstein (1975 a,b). Before embarking on the main object of the investigation, various studies were made on the production and purification of the alpha-haemolysin of S.aureus Wood 46. The production of alpha-, beta- and delta-haemolysins and protease(s) by S.aureus Wood 46 was biphasic, in agreement with the published data (Duncan and Cho, 1971; McNiven and Arbuthnott, 1972). Purified alphalysin prepared by ammonium sulphate precipitation, chromatography on controlled-pore glass and electrofocusing had a pI of 8.5, a specific haemolytic activity of 1.63 x 10.

description: Wind turbine rotor blades are subject to highly dynamic loads and designed for life cycles of at least 20 years, which means that materials are subjected to high-cycle fatigue. Fatigue is a design-driving loading for current and future blades. Bond lines of blades are exposed to a multi-axial stress-state due to the anisotropic thin-walled blade structure and curved, tapered, twisted, and airfoil-shaped blade geometry. To eliminate undesirable failure modes and thus increase the reliability of wind turbine rotor blades, standards and guidelines recommend that the multi-axial stress-states be taken into consideration for the limit state analysis. In addition, thermal residual stresses that develop during manufacture can have a significant impact on the fatigue life of the bond line. By means of a cyclic full-scale blade test of a commercial 81.6m long offshore blade, we validate a crack initiation model, which takes into account multi-axial thermal and mechanical stress-states, as well as the probabilistic stress-life, to predict the edge of crack initiation in the adhesive as well as the span-wise position. Both observations agreed well with the simulations. All residual normal stress components and cross-sectional plane shear stress made up the major part of the mean equivalent stress, while the mechanical stress amplitude components - longitudinal, peel, and cross-sectional plane shear stress - made up the major part of the equivalent stress amplitude.

description: Online social networks (OSNs) are increasingly being interrogated for their ability to facilitate both positive and negative influence on their users. Although the number of studies examining social influence in OSNs is increasing, the theoretical frameworks applied to OSN research are outdated. Therefore, this research adopts a multi-method approach to reframe and extend social influence theory to align with the unique contextual factors of OSNs. The findings contribute to the effective application of social influence theory in OSN research and refine digital social influence mechanisms for both research and practice.
Ultimate data hiding in quantum mechanics and beyond

description: The phenomenon of data hiding, i.e. the existence of pairs of states of a bipartite system that are perfectly distinguishable via general entangled measurements yet almost indistinguishable under LOCC, is a distinctive signature of nonclassicality. The relevant figure of merit is the maximal ratio (called data hiding ratio) between the distinguishability norms associated with the two sets of measurements we are comparing, typically all measurements vs LOCC protocols. For a bipartite $n\times n$ quantum system, it is known that the data hiding ratio scales as $n$, i.e. the square root of the real dimension of the local state space of density matrices. We show that for bipartite $n_A\times n_B$ systems the maximum data hiding ratio against LOCC protocols is $Θ\left(\min\{n_A,n_B\}\right)$. This scaling is better than the previously obtained upper bounds $O\left(\sqrt{n_A n_B}\right)$ and $\min\{n_A^2, n_B^2\}$, and moreover our intuitive argument yields constants close to optimal. In this paper, we investigate data hiding in the more general context of general probabilistic theories (GPTs), an axiomatic framework for physical theories encompassing only the most basic requirements about the predictive power of the theory. The main result of the paper is the determination of the maximal data hiding ratio obtainable in an arbitrary GPT, which is shown to scale linearly in the minimum of the local dimensions. We exhibit an explicit model achieving this bound up to additive constants, finding that the quantum mechanical data hiding ratio is only of the order of the square root of the maximal one. Our proof rests crucially on an unexpected link between data hiding and the theory of projective and injective tensor products of Banach spaces. Finally, we develop a body of techniques to compute data hiding ratios for a variety of restricted classes of GPTs that support further symmetries.

description: There exist zero-temperature states in quantum many-body systems that are fully factorized, thereby possessing vanishing entanglement, and hence being of no use as resource in quantum information processing tasks. Such states can become useful for quantum protocols when the temperature of the system is increased, and when the system is allowed to evolve under either the influence of an external environment, or a closed unitary evolution driven by its own Hamiltonian due to a sudden change in the system parameters. Using the one-dimensional anisotropic XY model in a uniform and an alternating transverse magnetic field, we show that entanglement of the thermal states, corresponding to the factorization points in the space of the system parameters, revives once or twice with increasing temperature. We also study the closed unitary evolution of the quantum spin chain driven out of equilibrium when the external magnetic fields are turned off, and show that considerable entanglement is generated during the dynamics, when the initial state has vanishing entanglement. Interestingly, we find that creation of entanglement for a pair of spins is possible when the system is made open to an external heat bath, interacting through that spin-pair having a repetitive quantum interaction.

Revisiting universality of the liquid-gas critical point in 2D

description: Critical point of liquid-gas (LG) transition does not conform with the paradigm of spontaneous symmetry breaking because there is no broken symmetry in both phases. This stimulated the ongoing debate about the nature of the universality class of the transition -- lasting since the creation of the theory of scaling. We revisit the conjecture that the LG criticality is that of the Ising model. Large scale Monte Carlo simulations of the LG criticality in 2D free space in combination with the numerical flowgram method give the critical indices agreeing with the Onsager values within the error of 1\%. The related problem about the role of higher order odd terms in the (real) $φ^4$ field model is addressed too. The scaling dimension of the $φ^5$ term at criticality is shown to be the same as of the linear one $φ$. We suggest that the role of all higher order odd terms is simply in generating the linear field operator at the criticality.

description: Lattice-based cryptosystems are promising candidates for the new standard of post-quantum security due to their efficiency and strong mathematical guarantees. However, their actual performance running on common platforms is believed to be affected heavily by implementation barriers. Therefore, this research studies the implementation of various lattice-based cryptosystems and their applications. We aim at finding out better software implementation techniques improving both the efficiency and security of such schemes. A systematic research on software implementation techniques of lattice-based cryptosystems and their applications is carried out during the study.

description: The balance held by Brownian motion between temporal regularity and randomness is embodied in a remarkable way by Levy's forgery of continuous functions. Here we describe how this property can be extended to forge arbitrary dependences between two statistical systems, and then establish a new Brownian independence test based on fluctuating random paths. We also argue that this result allows revisiting the theory of Brownian covariance from a physical perspective and opens the possibility of engineering nonlinear correlation measures from more general functional integrals.

description: Recently, heavily doped semiconductors are emerging as an alternate for low loss plasmonic materials. InN, belonging to the group III nitrides, possesses the unique property of surface electron accumulation (SEA) which provides two dimensional electron gas (2DEG) system. In this report, we demonstrated the surface plasmon properties of InN nanoparticles originating from SEA using the real space mapping of the surface plasmon fields for the first time. The SEA is confirmed by Raman studies which are further corroborated by photoluminescence and photoemission spectroscopic studies. The frequency of 2DEG corresponding to SEA is found to be in the THz region. The periodic fringes are observed in the near-field scanning optical microscopic images of InN nanostructures. The observed fringes are attributed to the interference of propagated and back reflected surface plasmon polaritons (SPPs). The observation of SPPs is solely attributed to the 2DEG corresponding to the SEA of InN. In addition, resonance kind of behavior with the enhancement of the near-field intensity is observed in the near-field images of InN nanostructures. Observation of SPPs indicates that InN with SEA can be a promising THz plasmonic material for the light confinement.

description: The experimental limitations in the signal enhancement and spatial resolution in spectroscopic imaging have been always a challenging task in the application of near-field spectroscopy for nanostructured materials in the sub-diffraction limit. In addition, the scattering efficiency also plays an important role in improving signal enhancement and contrast of the spectroscopic imaging of nanostructures by scattering of light. We report the effect of scattering efficiency in the Raman intensity enhancement, and contrast generation in near-field tip-enhanced Raman spectroscopic (TERS) imaging of one dimensional inorganic crystalline nanostructures of Si and AlN having a large variation in polarizability change. The Raman enhancement of pure covalently bonded Si nanowire (NW) is found to be two orders of higher in magnitude for the TERS imaging, as compared to that of AlN nanotip (NT) having a higher degree of ionic bonding, suggesting the importance of scattering efficiency of the materials in TERS imaging. The strong contrast generation due to higher signal enhancement in TERS imaging of Si NW also helped in achieving the better resolved spectroscopic images than that of the AlN NT. The study provides an insight into the role of scattering efficiency in the resolution of near-field spectroscopic images.

description: The exponential scaling of the wave function is a fundamental property of quantum systems with far reaching implications in our ability to process quantum information. A problem where these are particularly relevant is quantum state tomography. State tomography, whose objective is to obtain a full description of a quantum system, can be analysed in the framework of computational learning theory. In this model, quantum states have been shown to be Probably Approximately Correct (PAC)-learnable with sample complexity linear in the number of qubits. However, it is conjectured that in general quantum states require an exponential amount of computation to be learned. Here, using results from the literature on the efficient classical simulation of quantum systems, we show that stabiliser states are efficiently PAC-learnable. Our results solve an open problem formulated by Aaronson [Proc. R. Soc. A, 2088, (2007)] and propose learning theory as a tool for exploring the power of quantum computation.

description: A minimal perfect hash function (MPHF) bijectively maps a set S of objects to the first |S| integers. It can be used as a building block in databases and data compression. RecSplit [Esposito et al., ALENEX'20] is currently the most space efficient practical minimal perfect hash function. It heavily relies on trying out hash functions in a brute force way. We introduce rotation fitting, a new technique that makes the search more efficient by drastically reducing the number of tried hash functions. Additionally, we greatly improve the construction time of RecSplit by harnessing parallelism on the level of bits, vectors, cores, and GPUs. In combination, the resulting improvements yield speedups up to 239 on an 8-core CPU and up to 5438 using a GPU. The original single-threaded RecSplit implementation needs 1.5 hours to construct an MPHF for 5 Million objects with 1.56 bits per object. On the GPU, we achieve the same space usage in just 5 seconds. Given that the speedups are larger than the increase in energy consumption, our implementation is more energy efficient than the original implementation.

The electronic health records (EHR) of the patients reflect this complexity. Our research work is based on retrospective analyses of their EHR data, and seeks to answer four clinically relevant questions: First, how can we evaluate and improve the readiness of their EHR for modelling tasks? Second, are there identifiable, clinically relevant sub groups of patients in the cohort? Third, are there new normal values for physiological variables? Finally, we attempt modelling for the prediction of infections in the cohort.

description: Landauer's principle states that erasure of each bit of information in a system requires at least a unit of energy $k_B T \ln 2$ to be dissipated. In return, the blank bit may possibly be utilized to extract usable work of the amount $k_B T \ln 2$, in keeping with the second law of thermodynamics. While in principle any collection of spins can be utilized as information storage, work extraction by utilizing this resource in principle requires specialized engines that are capable of using this resource. In this work, we focus on heat and charge transport in a quantum spin Hall device in the presence of a spin bath. We show how a properly initialized nuclear spin subsystem can be used as a memory resource for a Maxwell's Demon to harvest available heat energy from the reservoirs to induce charge current that can power an external electrical load. We also show how to initialize the nuclear spin subsystem using applied bias currents which necessarily dissipate energy, hence demonstrating Landauer's principle. This provides an alternative method of "energy storage" in an all-electrical device. We finally propose a realistic setup to experimentally observe a Landauer erasure/work extraction cycle.

description: We theoretically explore the possibility of sausage instabilities developing on top of a kink instability in lengthening current-carrying magnetic flux tubes. Observations indicate that the dynamics of magnetic flux tubes in our cosmos and terrestrial experiments can involve topological changes faster than time scales predicted by resistive magnetohydrodynamics. Recent laboratory experiments suggest that hierarchies of instabilities, such as kink and Rayleigh-Taylor, could be responsible for initiating fast topological changes by locally accessing two fluid and kinetic regimes. Sausage instabilities can also provide this coupling mechanism between disparate scales. Flux tube experiments can be classified by the flux tube's evolution in a configuration space described by a normalized inverse aspect-ratio $\bar{k}$ and current-to-magnetic flux ratio $\barλ$. A lengthening current-carrying magnetic flux tube traverses this $\bar{k}$ - $\barλ$ space and crosses stability boundaries. We derive a single general criterion for the onset of the sausage and kink instabilities in idealized magnetic flux tubes with core and skin currents. The criterion indicates a dependence of the stability boundaries on current profiles and shows overlapping kink and sausage unstable regions in the $\bar{k}$ - $\barλ$ space with two free parameters. Numerical investigation of the stability criterion reduces the number of free parameters to a single one that describes the current profile, and confirms the overlapping sausage and kink unstable regions in $\bar{k}$ - $\barλ$ space. A lengthening, ideal current-carrying magnetic flux tube can therefore become sausage unstable after it becomes kink unstable.

description: We assess the skill and reliability of forecasts of winter and summer temperature, wind speed and irradiance over China, using the GloSea5 seasonal forecast system. Skill in such forecasts is important for the future development of seasonal climate services for the energy sector, allowing better estimates of forthcoming demand and renewable electricity supply. We find that although overall the skill from the direct model output is patchy, some high-skill regions of interest to the energy sector can be identified. In particular, winter mean wind speed is skilfully forecast around the coast of the South China Sea, related to skilful forecasts of the El Niño--Southern Oscillation. Such information could improve seasonal estimates of offshore wind power generation. Similarly, forecasts of winter irradiance have good skill in eastern central China, with possible use for solar power estimation. Much of China shows skill in summer temperatures, which derives from an upward trend. However, the region around Beijing retains this skill even when detrended. This temperature skill could be helpful in managing summer energy demand. While both the strengths and limitations of our results will need to be considered when developing seasonal climate services in the future, the outlook for such service development in China is promising.

Decision-Making Processes: Bangladeshi Large Enterprises’ Transition to Cloud ERP Systems
Creators: name: AHMED, RUMANA
Publisher: name: Monash University
Year: 2022
Subjects: classificationCode: 460999
subject: Information systems not elsewhere classified

description: The purpose of this doctoral study is to contribute to the currently limited understanding of large organisations’ transition from on-premise ERP systems to cloud in a developing country context. The adoption decision-making process has been analysed as an organisational change to answer the research questions investigating the what, why, and how of such a change. Corporate-level and Senior IT Managers alike were interviewed from four significant large organisations from Bangladesh. The data-driven theoretical framework, Structuration in the adoption decision-making process, combines the nature of, reasons for and purposes of making transition decisions. Outcomes have implications for both research and practice.
An Analysis of the Timber Framework of 'Oram Cottage', Knighton, Leicester
Creators: name: Clarke, Sophie J
Publisher: name: Archaeology Data Service
Year: 2022

description: Transactions of the Leicestershire Archaeological and Historical Society, 80, 61-70
description: This paper is based upon an RCHME level 3 survey of Oram Cottage, Church Lane, Knighton, Leicester (SK 5998 0130), undertaken in 2003 as part of coursework requirements for a Masters degree in Archaeology and Heritage at Leicester University. Oram Cottage is one of the few surviving examples of timber-framed building in Leicester and survey has revealed several phases of internal modification, resulting in the replacement of much of the early building fabric. Restoration of the property, undertaken by Leicester City Council in 1961, apparently sought to replicate a symmetrical aspect to the façade, for which there is no peg-hole evidence. Despite the later modifications, an original three-bay structure of one and a half storeys, with cross-passage entrance can be inferred from evidence in the early surviving timber work.

Sunken-Featured Buildings on a Late Romano-British Farmstead, Rectory Lane, Appleby Magna, Leicestershire
Creators: name: Clarke, Sophie J

Year: 2022

description: Transactions of the Leicestershire Archaeological and Historical Society, 84, 213-222
description: This paper presents the evidence for a number of sunken-featured buildings dating to the Romano-British period, excavated in 1999 by the University of Leicester Archaeological Services. These buildings formed part of a small, fourth-century agricultural settlement, located at a site close to the village of Appleby Magna. Structures of this type are more commonly associated with Anglo-Saxon settlement from the fifth century onwards, but there is increasing evidence to indicate an earlier origin for this building tradition.

description: The electromagnetically induced transparency (EIT) observations in two $Λ$-systems of $^{87}Rb$ atom, $|5^{2}S_{1/2} F=1\rangle \rightarrow |5^{2}P_{3/2} F'=1\rangle \leftarrow |5^{2}S_{1/2} F=2\rangle$ and $|5^{2}S_{1/2} F=1\rangle \rightarrow |5^{2}P_{3/2} F'=2\rangle \leftarrow |5^{2}S_{1/2} F=2\rangle$, have been investigated in detail and the results are found consistent with our proposed theoretical models. The second $Λ$-system provides EIT signal with higher magnitude than the first system, both in absence and in presence of an applied magnetic field. The observed steeper slope of the EIT signal in presence of the magnetic field can enable one to achieve tight frequency locking of lasers using these EIT signals.

The Neolithic and Bronze Age of Leicestershire and Rutland
Creators: name: Clay, Patrick N
Publisher: name: Archaeology Data Service
Year: 2023

description: Transactions of the Leicestershire Archaeological and Historical Society, 73, 1-18
description: An assessment of Neolithic and Bronze Age information from the Sites and Monuments Record, and three area surveys, for the counties of Leicestershire and Rutland suggests that far from being an area of little occupation during these periods it is in fact comparable with much of lowland Britain. Some clearance and occupation was taking place from the early fourth millennium BC onwards with expansion by the end of the third millennium BC. Proximity to water appears to have been a key factor in the location of 'core areas' and a movement of preferred settlement location from the headwaters downstream may be suggested.

description: Transactions of the Leicestershire Archaeological and Historical Society, 75, 1-19
description: Following on from the examination of the Neolithic and Bronze Age evidence from Leicestershire and Rutland (Clay 1999) this paper considers how the area now covered by the two counties changed during the Later Bronze Age and Iron Age. Settlement, land division, ritual, burial, trade, industry and material culture are examined and a model for society in this part of the East Midlands during the 1st millennium BC is suggested.
