description: Resource management in computing is a very challenging problem that involves making sequential decisions. Resource limitations, resource heterogeneity, dynamic and diverse nature of workload, and the unpredictability of fog/edge computing environments have made resource management even more challenging to be considered in the fog landscape. Recently Artificial Intelligence (AI) and Machine Learning (ML) based solutions are adopted to solve this problem. AI/ML methods with the capability to make sequential decisions like reinforcement learning seem most promising for these type of problems. But these algorithms come with their own challenges such as high variance, explainability, and online training. The continuously changing fog/edge environment dynamics require solutions that learn online, adopting changing computing environment. In this paper, we used standard review methodology to conduct this Systematic Literature Review (SLR) to analyze the role of AI/ML algorithms and the challenges in the applicability of these algorithms for resource management in fog/edge computing environments. Further, various machine learning, deep learning and reinforcement learning techniques for edge AI management have been discussed. Furthermore, we have presented the background and current status of AI/ML-based Fog/Edge Computing. Moreover, a taxonomy of AI/ML-based resource management techniques for fog/edge computing has been proposed and compared the existing techniques based on the proposed taxonomy. Finally, open challenges and promising future research directions have been identified and discussed in the area of AI/ML-based fog/edge computing.

description: Le forme di solidarietà sociale, la cooperazione internazionale e le strutture dei processi transnazionali che molti commentatori hanno individuato come le basi di un’‘Europa cosmopolita’ sono oggi messe a dura prova. Il processo più che decennale di cosmopolitizzazione apparente sembra retrocedere rapidamente, messo da parte o soggetto ad auto-distruzione. Se gli ultimi decenni hanno lasciato pensare al fatto che delle caratteristiche cosmopolite stessero emergendo con sempre maggiore evidenza e forza (anche se in modo non uniforme e controverso) sia rispetto alla Unione Europea (UE) come entità politico-giuridica sia all’interno dei suoi confini, oggi lo smantellamento del tessuto di vita ‘europea’ sembra puntare nella direzione opposta. Il saggio si pone la domanda di quanto davvero l’UE fosse cosmopolita prima dell’attuale crisi, e in che modo questa ha minato le sue caratteristiche cosmopolite. La tesi proposta è che l’UE è sempre stata, fin dalle origini, un’entità ambivalente dal punto di vista cosmopolita, in quanto strutturata su un cosmopolitismo liberal-economico basato sul mercato e su una concezione fondata sui diritti di cittadinanza e sulla democrazia, cioè una sorta di cosmopolitismo giuridico-politico. Entrambe le forme di cosmopolitismo sono sempre esistite in un rapporto ambivalente. Tuttavia, dalla fine degli anni Settanta, da quando cioè il cosmopolitismo liberal-economico è mutato in cosmopolitismo neo-liberista, la tensione tra i due è cresciuta in maniera evidente ed ha raggiunto un punto di rottura. Il saggio è una diagnosi della natura e delle conseguenze di questa situazione.

description: We report on a study of the 2300-2600ÅFeII/FeII* multiplets in the rest-UV spectra of star-forming galaxies at 1.01.5 Åand of the FeII* emission lines to W_r>0.5 Å. Whenever we can measure the systemic redshift of the galaxies from the [OII] emission line, we find that both the FeII and MgII absorption lines are blueshifted, indicative that both species trace gaseous outflows. We also find, however, that the FeII gas has generally lower outflow velocity relative to that of MgII. We investigate the variation of FeII line profiles as a function of the radiative transfer properties of the lines, and find that transitions with higher oscillator strengths are more blueshifted in terms of both line centroids and line wings. We discuss the possibility that FeII lines are suppressed by stellar absorptions. The lower velocities of the FeII lines relative to the MgII doublet, as well as the absence of spatially extended FeII* emission in 2D stacked spectra, suggest that most clouds responsible for the FeII absorption lie close (3~4 kpc) to the disks of galaxies. We show that the FeII/FeII* multiplets offer unique probes of the kinematic structure of galactic outflows.

description: We present the first 2.5 years of data from the MeerKAT Pulsar Timing Array (MPTA), part of MeerTime, a MeerKAT Large Survey Project. The MPTA aims to precisely measure pulse arrival times from an ensemble of 88 pulsars visible from the Southern Hemisphere, with the goal of contributing to the search, detection and study of nanohertz-frequency gravitational waves as part of the International Pulsar Timing Array. This project makes use of the MeerKAT telescope, and operates with a typical observing cadence of two weeks using the L-band receiver that records data from 856-1712 MHz. We provide a comprehensive description of the observing system, software, and pipelines used and developed for the MeerTime project. The data products made available as part of this data release are from the 78 pulsars that had at least $30$ observations between the start of the MeerTime programme in February 2019 and October 2021. These include both sub-banded and band-averaged arrival times, as well as the initial timing ephemerides, noise models, and the frequency-dependent standard templates (portraits) used to derive pulse arrival times. After accounting for detected noise processes in the data, the frequency-averaged residuals of $67$ of the pulsars achieved a root-mean-square residual precision of $< 1 μ\rm{s}$. We also present a novel recovery of the clock correction waveform solely from pulsar timing residuals, and an exploration into preliminary findings of interest to the international pulsar timing community. The arrival times, standards and full Stokes parameter calibrated pulsar timing archives are publicly available.

description: MAXI J1305-704 is a transient X-ray binary with a black hole primary. It was discovered on April 9, 2012, during its only known outburst. MAXI J1305-704 is also a high inclination low-mass X-ray binary with prominent dip features in its light curves, so we check the full catalog of 92 \emph{Swift}/XRT continuous observations of MAXI J1305-704, focusing only on the stable spectra. We select 13 ``gold" spectra for which the root mean square RMS <0.075 and the coronal scattered fraction $f_{\mathrm{sc}} \lesssim 25 \%$. These ``gold" data are optimal thermal-state observations for continuum-fitting modeling, in which the disk extends to the innermost-stable circular orbit and is geometrically thin. The black hole spin was unknown for this object before. By utilizing the X-ray continuum fitting method with the relativistic thin disk model \texttt{kerrbb2} and supplying the known dynamical binary system parameters, we find MAXI J1305-704 has a moderate spin ($a_{*}=0.87_{-0.13}^{+0.07}$) at a 68.3\% confidence level. This is the first determination of MAXI J1305-704's spin.

Genome dynamics and sleep: exploring the connection between heterochromatin modifications, DNA damage response, and sleep regulation
Creators: name: Falconio, Federica Alice
Publisher: name: Imperial College London
Year: 2023

description: Sleep is a fundamental behavior characterized by a state of inactivity, which has been observed in a wide range of species. Despite its conservation in evolution, the precise purpose of sleep remains shrouded in mystery. The application of innovative tools has significantly contributed to the exploration of the regulating mechanisms and functions involved in sleep, although further investigations is still required. In this thesis, I have examined sleep in two different contexts, using Drosophila melanogaster as model system. In the first part of this work, I combined a range of transcriptomics and immunostaining experiments, to analyze how gene expression changes in the brain upon acute and chronic sleep deprivation (SD) and found a role for histone methylases in regulating sleep-specific changes in gene expression. Prolonged SD leads to an overall decrease in gene expression driven by inhibitory histone methylation activity (H3K9) in the brain. The specific removal of H3K9 methylases, such as Su(var)3-9 or G9a, in neurons, interferes with this process, blocking sleep-specific changes in gene expression and canceling the fly’s internal homeostatic control of sleep. In the second part of this thesis, I dissected the recently hypothesized function of sleep, in facilitating DNA repair mechanisms. DNA damages, in particular double-stranded breaks (DSBs), are known to accumulate in the brain during wakefulness and decrease during sleep. Pharmacologically induction of DSBs leads to an increased baseline sleep in flies. Moreover, the pan-neuronal reduction of DNA repair-related genes, particularly p53, promotes increased sleep: the combination of chronic SD with the knockdown of p53 leads to heightened levels of neuronal DSBs and a reduction in lifespan. Unravelling the cellular basis for sleep drive may facilitate the improvement in restorative sleep quality for individuals dealing with sleep disorders and provide valuable insights into the relationship between sleep, aging, and neurodegenerative diseases.

description: We present a route to non-destructive functionalization of graphene via assembly of vertical all-carbon van der Waals heterostructures. To this end, we employ singlelayer graphene (SLG) sheets grown by low-pressure methane CVD on Cu foils and large-area dielectric ~1 nm thick amino-terminated carbon nanomembranes (NH2-CNMs) generated by electron-beam-induced crosslinking of aromatic self-assembled monolayers. We encapsulate SLG sheets on oxidized silicon wafers with NH2-CNMs via mechanical stacking and characterize structural, chemical and electronic properties of the formed heterostructures by Raman spectroscopy and X-ray photoelectron spectroscopy as well as by electric and electromagnetic transport measurements. We show that functional amino groups are brought in close vicinity of the SLG sheets and that their transport characteristics are not impaired by this functionalization; moreover, we demonstrate a functional response of the heterostructure devices to the protonation of the amino groups in water. Due to its relative simplicity, the suggested approach opens broad avenues for implementations in graphene-based electronic devices where non-destructive chemical functionalization of graphene is required (e.g., for engineering electrical transducers for chemical and bio-sensing) or as complementary dielectric to graphene in hieratical heterostructures.

description: We report a quantitative experimental study of the crystallization kinetics of supercooled quantum liquid mixtures of para-hydrogen (pH$_2$) and ortho-deuterium (oD$_2$) by high spatial resolution Raman spectroscopy of liquid microjets. We show that in a wide range of compositions the crystallization rate of the isotopic mixtures is significantly reduced with respect to that of the pure substances. To clarify this behavior we have performed path-integral simulations of the non-equilibrium pH$_2$-oD$_2$ liquid mixtures, revealing that differences in quantum delocalization between the two isotopic species translate into different effective particle sizes. Our results provide first experimental evidence for crystallization slowdown of quantum origin, offering a benchmark for theoretical studies of quantum behavior in supercooled liquids.

description: Athletes routinely undergo fitness evaluations to evaluate their training progress. Typically, these evaluations require a trained professional who utilizes specialized equipment like force plates. For the assessment, athletes perform drop and squat jumps, and key variables are measured, e.g. velocity, flight time, and time to stabilization, to name a few. However, amateur athletes may not have access to professionals or equipment that can provide these assessments. Here, we investigate the feasibility of estimating key variables using video recordings. We focus on jump velocity as a starting point because it is highly correlated with other key variables and is important for determining posture and lower-limb capacity. We find that velocity can be estimated with a high degree of precision across a range of athletes, with an average R-value of 0.71 (SD = 0.06).

description: This study uses the Gini coefficient to analyze farm household income inequality and decomposes the inequality by farm types during 2008~2017. The Gini coefficient is decomposed into three elements: between-groups, within-groups, and residual term contributions, and the farm households are classified by farm owner’s age and standard farm size. This study shows that the Gini coefficient has not changed significantly in the last 10 years. However, the relative contributions of the elements have changed significantly due to the structural change in agriculture: the aging of farm owners and the decrease in farm size per household. Specifically, the relative contribution of small and older farmers to the Gini coefficient has increased over time.
Exploiting contextual anomalies to detect perception attacks on cyber-physical systems
Creators: name: Hau, Zhongyuan
Publisher: name: Imperial College London
Year: 2024

description: Perception is a key component in Cyber-Physical Systems (CPS) where information is collected by sensors and processed for decision-making. Perception attacks have been crafted specifically to subvert the CPS decision-making process. CPS are used in many safety-critical applications and perception attacks could lead to catastrophic consequences. Hence, there is a need to study how effective detection systems can be designed to detect such attacks. Designing detection systems for perception attacks in CPS is difficult as each CPS is domain-specific and existing detection systems for one CPS in one domain cannot be easily transferred to another. Current proposed detection systems are implemented to mitigate specific attacks and most offer only high-level insights on how the detection is performed. A systematic approach to designing detection for perception attacks that is generally applicable for CPS is needed. We propose a threat-modelling based methodology to design perception attack detection systems for CPS. An information model of the CPS, together with a threat model are used to determine how information correlations, defined as invariants, can be exploited as context for detecting anomalies. The proposed methodology was first applied to design perception attack detection Autonomous Driving, where we tackle the problem of attacks on LiDAR-based perception to spoof and hide objects. A novel specified physical invariant, the 3D shadow, was identified and shown that it is a robust verifier of genuine objects and was used to detect spoofed and hidden objects. Another learnt physical invariant of an object, where its motion needs to be temporally consistent, was shown to be effective in detecting object spoofing. Secondly, we apply the methodology to design the detection of false data injection in low-density sensor networks. We show that the use of learnt correlations across sensor measurements is effective even in a constrained setting with few sensors and heterogeneous data.

description: The concept of the PT-symmetry, originating from the quantum field theory, has been intensively investigated in optics, stimulated by the similarity between the Schrödinger equation and the paraxial wave equation that governs the propagation of light in a guiding structure. We go beyond the bounds of the paraxial approximation and demonstrate, using the solution of the Maxwell's equations for light beams propagating in deeply subwavelength waveguides and periodic lattices with "balanced" gain and loss, that the PT symmetry may stay unbroken in this setting. Moreover, the PT-symmetry in subwavelength optical structures may be restored after being initially broken upon the increase of gain and loss. Critical gain/loss levels, at which the breakup and subsequent restoration of the PT symmetry occur, strongly depend on the scale of the structure.

description: Pauli Exclusion Principle (PEP) violations induced by space-time non-commutativity, a class of universality for several models of Quantum Gravity, are investigated by the VIP-2 Lead experiment at the Gran Sasso underground National Laboratory of INFN. The VIP-2 Lead experimental bound on the non-commutative space-time scale $Λ$ excludes $θ$-Poincaré far above the Planck scale for non vanishing ``electric-like" components of $θ_{μν}$, and up to $6.9 \cdot 10^{-2}$ Planck scales if they are null. Therefore, this new bound represents the tightest one so far provided by atomic transitions tests. This result strongly motivates high sensitivity underground X-ray measurements as critical tests of Quantum Gravity and of the very microscopic space-time structure.

description: We report on the development of the HEC2 (High Energy Compression and Current) charge breeder, a possible high performance successor to REXEBIS at ISOLDE. The new breeder would match the performance of the HIE-ISOLDE linac upgrade and make full use of the possible installation of a storage ring at ISOLDE (the TSR@ISOLDE initiative [1]). Dictated by ion beam acceptance and capacity requirements, the breeder features a 2-3.5 A electron beam. In many cases very high charge states, including bare ions up to Z=70 and Li/Na-like up to Z=92 could be requested for experiments in the storage ring, therefore, electron beam energies up to 150 keV are required. The electron-beam current density needed for producing ions with such high charge states at an injection rate into TSR of 0.5-1 Hz is between 10 and 20 kA/cm2, which agrees with the current density needed to produce A/q<4.5 ions for the HIE-ISOLDE linac with a maximum repetition rate of 100 Hz. The first operation of a prototype electron gun with a pulsed electron beam of 1.5 A and 30 keV was demonstrated in a joint experiment with BNL [2]. In addition, we report on further development aiming to achieve CW operation of an electron beam having a geometrical transverse ion-acceptance matching the injection of 1+ ions (11.5 μm), and an emittance/energy spread of the extracted ion beam matching the downstream mass separator and RFQ (0.08 μm normalized / +/- 1% ).

description: The work is motivated by the Faraday cage effect. We consider the Helmholtz equation over a 3D-domain containing a thin heterogeneous interface of thickness $δ\ll 1$. The layer has a $δ-$periodic structure in the in-plane directions and is cylindrical in the third direction. The periodic layer has one connected component and a collection of isolated regions. The isolated region in the thin layer represents air or liquid, and the connected component represents a solid metal grid with a $δ$ thickness. The main issue is created by the contrast of the coefficients in the air and in the grid and that the zero-order term has a complex-valued coefficient in the connected faze while a real-valued in the complement. An asymptotic analysis with respect to $δ\to 0$ is provided, and the limit Helmholtz problem is obtained with the Dirichlet condition on the interface. The periodic unfolding method is used to find the limit.
Clustering of buoyant floating tracers in the marine environment

description: Floating contaminants in the marine environment, such as buoyant microplastic particles, are of increasing concern. This is due to the rapid rate at which they are being introduced to the ocean, and observations that they can accumulate on the oceanic gyres, where they form dense clusters. There is reason to believe that microplastic particles could have severe effects on previously isolated ocean ecosystems. Prior modelling of the flow of floating material has been limited by the available data of convergent surface ocean currents. In this thesis, we will construct idealised models of floating tracers from first principles. We will then use these models to explore the dynamics of cluster formation in kinematic and quasigeostrophic ocean velocity fields, with applications to the flow of microplastics, inertial Lagrangian drifters, and organic material. These idealised models will further serve as a test-bed for clustering metrics that can be used to make quantitative comparisons between clustering models. The insights derived from these metrics will motivate best practices which can improve the methodology of clustering models in more realistic scenarios.

description: The evolutions of a neutron star's rotation and magnetic field (B-field) have remained unsolved puzzles for over half a century. We ascribe the rotational braking torques of pulsar to both components, the standard magnetic dipole radiation (MDR) and particle wind flow ( MDR + Wind, hereafter named MDRW), which we apply to the Crab pulsar (B0531 + 21), the only source with a known age and long-term continuous monitoring by radio telescope. Based on the above presumed simple spin-down torques, we obtain the exact analytic solution on the rotation evolution of the Crab pulsar, together with the related outcomes as described below: (1) unlike the constant characteristic B-field suggested by the MDR model, this value for the Crab pulsar increases by a hundred times in 50~kyr while its real B-field has no change; (2) the rotational braking index evolves from $\sim$3 to 1 in the long-term, however, it drops from 2.51 to 2.50 in $\sim$45 years at the present stage, while the particle flow contributes approximately 25% of the total rotational energy loss rate; (3) strikingly, the characteristic age has the maximum limit of $\sim$10 kyr, meaning that it is not always a good indicator of real age. Furthermore, we discussed the evolutionary path of the Crab pulsar from the MDR to the wind domination by comparing it with the possible wind braking candidate pulsar PSR J1734-3333.

description: Magnetohydrodynamic (MHD) turbulence in the majority of natural systems, including the interstellar medium, the solar corona, and the solar wind, has Reynolds numbers far exceeding the Reynolds numbers achievable in numerical experiments. Much attention is therefore drawn to the universal scaling properties of small-scale fluctuations, which can be reliably measured in the simulations and then extrapolated to astrophysical scales. However, in contrast with hydrodynamic turbulence, where the universal structure of the inertial and dissipation intervals is described by the Kolmogorov self-similarity, the scaling for MHD turbulence cannot be established based solely on dimensional arguments due to the presence of an intrinsic velocity scale -- the Alfven velocity. In this Letter, we demonstrate that the Kolmogorov first self-similarity hypothesis cannot be formulated for MHD turbulence in the same way it is formulated for the hydrodynamic case. Besides profound consequences for the analytical consideration, this also imposes stringent conditions on numerical studies of MHD turbulence. In contrast with the hydrodynamic case, the discretization scale in numerical simulations of MHD turbulence should decrease faster than the dissipation scale, in order for the simulations to remain resolved as the Reynolds number increases.

description: We investigate cosmological models with two interacting fluids: dark energy and dark matter in flat Friedmann-Robertson-Walker universe. The interaction between dark energy and dark matter is described in terms of the parameters present in the inhomogeneous equation of state when allowance is made for bulk viscosity, for the Little Rip, the Pseudo Rip, and the bounce universes. We obtain analytic representation for characteristic properties in these cosmological models, in particular the bulk viscosity $ζ=ζ(H,t)$ as function of Hubble parameter and time. We discuss the corrections of thermodynamical parameters in the equations of state due coupling between the viscous fluid and dark matter. Some common properties of these corrections are elucidated.

Multi-functional wireless networks: integrated sensing and communications, full-duplex, and unlimited sensing
Creators: name: Liu, Ziang
Publisher: name: Imperial College London
Year: 2024

description: Next generation wireless communication networks are expected to be multi- functional to support emerging requirements, e.g. high data transmission rates, high-quality wireless connectivity supporting a large number of devices, and highly accurate and robust sensing capability. To realize these demands, cutting- edge technologies such as integrated sensing and communication (ISAC), massive multiple-input multiple-output (MIMO), satellite communications, and full-duplex (FD) communications system requires further exploration and development. Specifically, challenges persist in optimizing these systems. In mono-static ISAC system, radar returns are drowned by the strong residual self interference (SI) stemming from the transmitter. ISAC satellite communications systems encounter challenges on interference control and power limitations. Massive MIMO systems confront the high power consumption and receiver analog-to-digital converter (ADC) saturation. Additionally, FD communica- tion systems face the difficulties of suppressing SI. To overcome the mentioned challenges, this thesis introduces novel approaches, which are based on con- vex optimization techniques and unlimited sensing theorem. Subsequently, this thesis provides introductions to the background context, followed by a thorough review of the techniques utilized in the proposed solutions. In the following chapters, explanations of these solutions are presented. Finally, this thesis wraps up with a comprehensive conclusion.

description: Centrosymmetry often mediates Perfect State Transfer (PST) in various complex systems ranging from quantum wires to photosynthetic networks. We introduce the Deformed Centrosymmetric Ensemble (DCE) of random matrices, $H(λ) \equiv H_+ + λH_-$, where $H_+$ is centrosymmetric while $H_-$ is skew-centrosymmetric. The relative strength of the $H_\pm$ prompts the system size scaling of the control parameter as $λ= N^{-\fracγ{2}}$. We propose two quantities, $\mathcal{P}$ and $\mathcal{C}$, quantifying centro- and skewcentro-symmetry, respectively, exhibiting second order phase transitions at $γ_\text{P}\equiv 1$ and $γ_\text{C}\equiv -1$. In addition, DCE posses an ergodic transition at $γ_\text{E} \equiv 0$. Thus equipped with a precise control of the extent of centrosymmetry in DCE, we study the manifestation of $γ$ on the transport properties of complex networks. We propose that such random networks can be constructed using the eigenvectors of $H(λ)$ and establish that the maximum transfer fidelity, $F_T$, is equivalent to the degree of centrosymmetry, $\mathcal{P}$.
