description: We present the wavelength calibration for the lenslet-based Integral Field Spectrograph (IFS) that serves as the science instrument for the Gemini Planet Imager (GPI). The GPI IFS features a 2.7" x 2.7" field of view and a 190 x 190 lenslet array (14.3 mas/lenslet) operating in $Y$, $J$, $H$, and $K$ bands with spectral resolving power ranging from $R$ $\sim$ 35 to 78. Due to variations across the field of view, a unique wavelength solution is determined for each lenslet characterized by a two-dimensional position, the spectral dispersion, and the rotation of the spectrum with respect to the detector axes. The four free parameters are fit using a constrained Levenberg-Marquardt least-squares minimization algorithm, which compares an individual lenslet's arc lamp spectrum to a simulated arc lamp spectrum. This method enables measurement of spectral positions to better than 1/10th of a pixel on the GPI IFS detector using Gemini's facility calibration lamp unit GCAL, improving spectral extraction accuracy compared to earlier approaches. Using such wavelength calibrations we have measured how internal flexure of the spectrograph with changing zenith angle shifts spectra on the detector. We describe the methods used to compensate for these shifts when assembling datacubes from on-sky observations using GPI.

description: The ability to efficiently load functions on quantum computers with high fidelity is essential for many quantum algorithms. We introduce the Fourier Series Loader (FSL) method for preparing quantum states that exactly encode multi-dimensional Fourier series using linear-depth quantum circuits. The FSL method prepares a ($Dn$)-qubit state encoding the $2^{Dn}$-point uniform discretization of a $D$-dimensional function specified by a $D$-dimensional Fourier series. A free parameter $m < n$ determines the number of Fourier coefficients, $2^{D(m+1)}$, used to represent the function. The FSL method uses a quantum circuit of depth at most $2(n-2)+\lceil \log_{2}(n-m) \rceil + 2^{D(m+1)+2} -2D(m+1)$, which is linear in the number of Fourier coefficients, and linear in the number of qubits ($Dn$) despite the fact that the loaded function's discretization is over exponentially many ($2^{Dn}$) points. We present a classical compilation algorithm with runtime $O(2^{3D(m+1)})$ to determine the FSL circuit for a given Fourier series. The FSL method allows for the highly accurate loading of complex-valued functions that are well-approximated by a Fourier series with finitely many terms. We report results from noiseless quantum circuit simulations, illustrating the capability of the FSL method to load various continuous 1D functions, and a discontinuous 1D function, on 20 qubits with infidelities of less than $10^{-6}$ and $10^{-3}$, respectively. We also demonstrate the practicality of the FSL method for near-term quantum computers by presenting experiments performed on the Quantinuum H$1$-$1$ and H$1$-$2$ trapped-ion quantum computers: we loaded a complex-valued function on 3 qubits with a fidelity of over $95\%$, as well as various 1D real-valued functions on up to 6 qubits with classical fidelities $\approx 99\%$, and a 2D function on 10 qubits with a classical fidelity $\approx 94\%$.

On the Security Assessment of the Cloud
Creators: name: Manzoor, Salman
Publisher: name: Lancaster University
Year: 2022

description: Cloud computing is an enabling technology paradigm that provides access to the geodistributed pool of resources that are rapidly and flexibly provisioned at run-time with minimum management from the user. These benefits have driven the proliferation of the Cloud over the last decade. Many organizations have migrated to the Cloud or have a Cloudfirst strategy for their businesses. Despite these benefits, the security of the Cloud has been flagged as among the top concerns by its users. To address security concerns, Threat Analysis (TA) is often advocated to ascertain a system’s exposure to threats. A plethora of TA techniques exist that focus on analyzing threats to targeted assets at the system’s level (e.g., components, hardware) or at the user’s level (e.g., virtual machine) in the Cloud. These techniques are effective, but their applicability is limited beyond their targeted asset. However, the Cloud is a complex system entailing both the physical and virtual resources. Moreover, these resources can instantiate, migrate across physical hosts, or decommission to provide rapid resource elasticity to the users. On this background, this thesis aims at assessing the security of the Cloud holistically by considering the interactions among the services/components involved in the operational stack of the Cloud. In this regard, a technology-agnostic information flow model is developed that represents the Cloud’s functionality through a set of conditional transitions. Furthermore, threats are added to the model to analyze their impact on the Cloud. This enables the exploration of a threat’s behavior and its propagation across the Cloud and supports assessing the security of the Cloud by analyzing the impact of multiple threats across various operational layers/assets. Using public information on threats from the National Vulnerability Database (NVD), actual Cloud attacks were traced and speculatively postulated alternate potential attack paths. Furthermore, the thesis also investigates different threats with similar indicators of compromise (e.g., attack patterns) to be considered in the security assessment along with the specific user’s requirements. Finally, the thesis also targets the evaluation of potential violations from the Cloud providers that breach users’ requirements. The results presented in the thesis demonstrate that by ascertaining the attack paths and considering the interplay between threats and security requirements, the security of the Cloud can be comprehensively assessed.

description: In nuclear fusion, Microwave Plasma Assisted (MPA) Chemical Vapour Deposition (CVD) polycrystalline diamond is the only material allowing for transmission of high power microwave beams (1-2 MW) in long-pulse gyrotron operations. The reason lies in the combination of extraordinary thermal, mechanical and optical properties of diamond, which is used in the shape of disks having thickness of 1 to 2 mm for windows. Being diamond a brittle material, failure to fracture is the main failure mode. Accordingly, an appropriate mechanical characterization is required as diamond plays a major safety role in fusion machines. Due to limited body of work in literature, fracture toughness measurements have to be first carried out for this material and then a design criterion for structural integrity assessment has to be applied. In this work, the preliminary activities aiming to define the optimum experimental measurement method of fracture toughness for thin diamond samples are shown and discussed. An outlook to the next steps is also given.

description: On the basis of the recent group classification of the one-dimensional magnetohydrodynamics (MHD) equations in cylindrical geometry, the construction of symmetry-preserving finite-difference schemes with conservation laws is carried out. New schemes are constructed starting from the classical completely conservative Samarsky-Popov schemes. In the case of finite conductivity, schemes are derived that admit all the symmetries and possess all the conservation laws of the original differential model, including previously unknown conservation laws. In the case of a frozen-in magnetic field (when the conductivity is infinite), various schemes are constructed that possess conservation laws, including those preserving entropy along trajectories of motion. The peculiarities of constructing schemes with an extended set of conservation laws for specific forms of entropy and magnetic fluxes are discussed.

description: In this paper, we perform a time-domain analysis of the higher-order Allan variance for atomic clock models of arbitrary order. Adopting a standard atomic clock model where the time series of the clock reading deviation is expressed as a Wiener or integrated Wiener process, we define the higher-order Allan variance as the mean squared higher-order difference of the clock reading deviation. The main results of this paper are threefold. First, we prove that the higher-order difference operation of the clock reading deviation, which can be interpreted as a linear aggregation with binomial coefficients, is not only sufficient but also necessary for a resulting aggregated time series to be an independent and identically distributed Gaussian process. Second, we derive a complete analytical expression of the higher-order Allan variance, which consists of both time-dependent and time-independent terms. Third, we prove that the higher-order Allan variance is time-independent if and only if the order of difference operation is greater than or equal to the order of the atomic clock model.

description: In many active galaxies, the X-ray reflection features from the innermost regions of the accretion disc are relativistically distorted. This distortion allows us to measure parameters of the black hole such as its spin. The ratio in flux between the direct and the reflected radiation, the so-called reflection fraction, is determined directly from the geometry and location of primary source of radiation. We calculate the reflection fraction in the lamp post geometry in order to determine its maximal possible value for a given value of black hole spin. We show that high reflection fractions in excess of 2 are only possible for rapidly rotating black holes, suggesting that the high spin sources produce the strongest relativistic reflection features. Using simulations we show that taking this constraint into account does significantly improve the determination of the spin values. We make software routines for the most popular X-ray data analysis packages available that incorporate these additional constraints.

description: The work in this thesis is centred around exploring the transport properties induced by periodically driving topologically non-trivial systems. In particular, it focuses upon the signatures associated with Majorana modes in 1D topological superconductors and their adiabatic manipulations, in anticipation of the next generation of experiments pursuing the realization and control of such excitations, which have been stipulated as the potential building blocks of robust quantum computation. We examine two distinct ways by which external driving can influence a system's topology. Firstly, we focus upon systems for which the modulation results in the emergence of additional topological phases, not present in their static counterparts, the classification of which is not well defined by the usual topological invariants associated with the energy spectrum of the bulk system. For such systems, transport properties are vital in identifying non-trivial topological regimes and, with this motivation, we examine the relationship between driven scattering matrix topological invariants and conductance signatures. Secondly, we determine the transport statistics associated with the adiabatic manipulation of topological excitations appearing in static systems, with a specific focus upon a Majorana braiding protocol. In this way, we demonstrate that the topological protection of the operation is reflected in geometric contributions to the heat transport induced by the driving. In addition to providing potential experiential signatures of such manipulations, this analysis also sheds light on the influence of periodic driving upon exchange fluctuation theorems, that govern the thermodynamics of non-equilibrium quantum systems, and also the performance of such protected operations as nanoscale thermal machines.

description: Certain fractional quantum Hall edges have been predicted to undergo quantum phase transitions which reduce the number of edge channels and at the same time bind electrons together. However, detailed studies of experimental signatures of such a ``binding transition'' remain lacking. Here, we propose quantum transport signatures with focus on the edge at filling $ν=9/5$. We demonstrate theoretically that in the regime of non-equilibrated edge transport, the bound and unbound edge phases have distinct conductance and noise characteristics. We also show that for a quantum point contact in the strong back-scattering regime, the bound phase produces a minimum Fano-factor $F_{SBS}=3$ corresponding to three-electron tunneling, whereas single electron tunneling is strongly suppressed at low energies. Together with recent experimental developments, our results will be useful for detecting binding transitions in the fractional quantum Hall regime.

description: Recent work in scientific machine learning (SciML) has focused on incorporating partial differential equation (PDE) information into the learning process. Much of this work has focused on relatively "easy" PDE operators (e.g., elliptic and parabolic), with less emphasis on relatively "hard" PDE operators (e.g., hyperbolic). Within numerical PDEs, the latter problem class requires control of a type of volume element or conservation constraint, which is known to be challenging. Delivering on the promise of SciML requires seamlessly incorporating both types of problems into the learning process. To address this issue, we propose ProbConserv, a framework for incorporating conservation constraints into a generic SciML architecture. To do so, ProbConserv combines the integral form of a conservation law with a Bayesian update. We provide a detailed analysis of ProbConserv on learning with the Generalized Porous Medium Equation (GPME), a widely-applicable parameterized family of PDEs that illustrates the qualitative properties of both easier and harder PDEs. ProbConserv is effective for easy GPME variants, performing well with state-of-the-art competitors; and for harder GPME variants it outperforms other approaches that do not guarantee volume conservation. ProbConserv seamlessly enforces physical conservation constraints, maintains probabilistic uncertainty quantification (UQ), and deals well with shocks and heteroscedasticities. In each case, it achieves superior predictive performance on downstream tasks.

description: Early stages of the investigations at Hofstaðir directed by the Archaeological Institute Iceland revealed that substantial amounts of well-preserved animal bone were present in contexts throughout the site, with a major concentration in the fill of the large sunken featured structure G. The site directors kindly involved the NABO zooarchaeologists (led through various seasons by Tom McGovern and Sophia Perdikaris), and the zooarchaeology team was able to participate directly in the field excavations from 1996 onwards. The modern open area excavation of this major Viking Age hall and its associated buildings offered a unique opportunity for North Atlantic zooarchaeology, allowing comparisons of bone assemblages from fully excavated middens and structures and the combination of horizontal and vertical stratigraphic perspectives on the interpretation of site formation processes. The close cooperation between excavators and specialists continued from fieldwork through post-excavation analysis, and has unquestionably improved the quality of this report. The analysis and interpretation of the Hofstaðir archaeofauna has also greatly benefited from comparative zooarchaeological evidence from contemporary nearby sites in the Mývatn area (Mývatnssveit) carried out under the larger Landscapes of Settlement project, and this analysis will make use of comparative zooarchaeological data from the contemporary sites of Sveigakot (SVK) and Hrísheimar (HRH).

description: In systems where the standard $α$ effect is inoperative, one often explains the existence of mean magnetic fields by invoking the `incoherent $α$ effect', which appeals to fluctuations of the mean kinetic helicity at a mesoscale. Most previous studies, while considering fluctuations in the mean kinetic helicity, treated the mean turbulent kinetic energy at the mesoscale as a constant, despite the fact that both these quantities involve second-order velocity correlations. The mean turbulent kinetic energy affects the mean magnetic field through both turbulent diffusion and turbulent diamagnetism. In this work, we use a double-averaging procedure to analytically show that fluctuations of the mean turbulent kinetic energy at the mesoscale (giving rise to $η$-fluctuations at the mesoscale, where the scalar $η$ is the turbulent diffusivity) can lead to the growth of a large-scale magnetic field even when the kinetic helicity is zero pointwise. Constraints on the operation of such a dynamo are expressed in terms of dynamo numbers that depend on the correlation length, correlation time, and strength of these fluctuations. In the white-noise limit, we find that these fluctuations reduce the overall turbulent diffusion, while also contributing a drift term which does not affect the growth of the field. We also study the effects of nonzero correlation time and anisotropy. Turbulent diamagnetism, which arises due to inhomogeneities in the turbulent kinetic energy, leads to growing mean field solutions even when the $η$-fluctuations are statistically isotropic.

description: Graph convolutional networks (GCNs) were a great step towards extending deep learning to unstructured data such as graphs. But GCNs still need a constructed graph to work with. To solve this problem, classical graphs such as $k$-nearest neighbor are usually used to initialize the GCN. Although it is computationally efficient to construct $k$-nn graphs, the constructed graph might not be very useful for learning. In a $k$-nn graph, points are restricted to have a fixed number of edges, and all edges in the graph have equal weights. We present a new way to construct the graph and initialize the GCN. It is based on random projection forest (rpForest). rpForest enables us to assign varying weights on edges indicating varying importance, which enhanced the learning. The number of trees is a hyperparameter in rpForest. We performed spectral analysis to help us setting this parameter in the right range. In the experiments, initializing the GCN using rpForest provides better results compared to $k$-nn initialization.

description: We present the results of both laboratory and on sky astrometric characterization of the Gemini Planet Imager (GPI). This characterization includes measurement of the pixel scale of the integral field spectrograph (IFS), the position of the detector with respect to north, and optical distortion. Two of these three quantities (pixel scale and distortion) were measured in the laboratory using two transparent grids of spots, one with a square pattern and the other with a random pattern. The pixel scale in the laboratory was also estimate using small movements of the artificial star unit (ASU) in the GPI adaptive optics system. On sky, the pixel scale and the north angle are determined using a number of known binary or multiple systems and Solar System objects, a subsample of which had concurrent measurements at Keck Observatory. Our current estimate of the GPI pixel scale is 14.14 $\pm$ 0.01 millarcseconds/pixel, and the north angle is -1.00 $\pm$ 0.03$°$. Distortion is shown to be small, with an average positional residual of 0.26 pixels over the field of view, and is corrected using a 5th order polynomial. We also present results from Monte Carlo simulations of the GPI Exoplanet Survey (GPIES) assuming GPI achieves ~1 milliarcsecond relative astrometric precision. We find that with this precision, we will be able to constrain the eccentricities of all detected planets, and possibly determine the underlying eccentricity distribution of widely separated Jovians.

description: The Ancylonema genus includes the most-documented microalgae on glaciers and ice sheets worldwide. There is significant interest in these microalgae in the context of climate change, considering their role in lowering surface ice albedo and acceleration of ice melt. However, currently, no cultures of the two closely related species A. nordenskiöldii or A. alaskanum have been established, restricting our ability to study these globally important species under laboratory conditions. We established and kept cultures of Ancylonema sp. alive for up to 2 years, by testing and optimizing different growth media and parameters. Maximum growth was achieved when using 1:100 diluted media with soil extract and low light intensity (300 µmol m−2s−1). However, as a consequence of incubation in lab conditions, some of the cultures lost their purpurogallin pigmentation and appeared green. Sanger sequencing of the ribulose-1,5 bisphosphate carboxylase/oxygenase large subunit (rbcL) marker gene revealed a large genetic diversity (possibly cryptic) and confirmed the cultures as falling within the same clade as A. nordenskiöldii and A. alaskanum. Growth experiments allowed us to estimate a division rate of between 15 ± 5.2 and 21.9 ± 4.8 days. This is up to 4 times slower than current field-based estimates (3.75–5.5 days) and indicates that, despite the successful growth and long-term maintenance of the cultures, laboratory settings can be further improved to achieve optimal growth conditions.

description: PIFE was first used as an acronym for protein-induced fluorescence enhancement, which refers to the increase in fluorescence observed upon the interaction of a fluorophore, such as a cyanine, with a protein. This fluorescence enhancement is due to changes in the rate of cis/trans photoisomerisation. It is clear now that this mechanism is generally applicable to interactions with any biomolecule and, in this review, we propose that PIFE is thereby renamed according to its fundamental working principle as photoisomerisation-related fluorescence enhancement, keeping the PIFE acronym intact. We discuss the photochemistry of cyanine fluorophores, the mechanism of PIFE, its advantages and limitations, and recent approaches to turn PIFE into a quantitative assay. We provide an overview of its current applications to different biomolecules and discuss potential future uses, including the study of protein-protein interactions, protein-ligand interactions and conformational changes in biomolecules.
