The fluid mechanics of hybrid ventilation
Creators: name: Connick, Owen
Publisher: name: Imperial College London
Year: 2013

description: A low-energy ventilation system is often incorporated as one of the major energy saving measures in sustainable building design. These systems often employ a hybrid strategy in which mechanical equipment, governed by a computer controlled building management system, is used to assist or manage a naturally-driven airflow – the latter occurring due to the density difference between warm air inside and cooler air outside the room. Hybrid ventilation flows are poorly understood and the principal aim of the research was to enhance our understanding of the fluid mechanics through complementary theoretical and experimental modelling. The research begins by comparing solely natural and solely mechanical ventilation of a room. The hybrid ventilation of a room is then considered under the combined effect of naturally occurring and mechanically imposed pressure differences, in which a mechanical fan imposes a fixed airflow rate through one vent, thereby altering the natural pressure distribution. Simplified theoretical models, to describe the ventilation airflow rate through a room and the resulting mean air temperature, were developed for solely natural ventila- tion, solely mechanical ventilation and, finally, hybrid ventilation. At each stage the theoretical model was compared with results from small-scale experiments, and good agreement was demonstrated. From the theoretical investigation, the neutral pressure level emerged as a key pa- rameter in determining the characteristics of the ventilation airflow. Moreover, it was found that the airflow rate through an open vent can be controlled remotely by managing the position of the neutral pressure level, and that this can be achieved by varying the magnitude of the mechanically imposed airflow rate. Experimental investigations revealed that, as the neutral pressure level approached the plane of a vent, quasi-steady pulsing flows and bi-directional or exchange flows were observed. The complicated fluid dynamics involved in these flows provides inspiration for significant future work.

description: This research conducts an in-depth examination of various risk management methodologies in financial trading, evolving from the high-risk, reward-driven YOLO Criterion to the advanced and nuanced Justus Criterion. It delves into how each methodology navigates the delicate equilibrium between growth opportunities and the inherent risks of significant losses, factoring in the dynamics of win probabilities and risk-reward scenarios. Introducing a layered analytical framework, this paper delineates the progression from the probabilistic foundations laid by the Kelly Criterion through to the adaptable constructs of the Tax and Just Criteria, culminating in the development of the bespoke Ad’Just Criterion. The pinnacle of this evolutionary journey is the Justus Criterion, which adeptly integrates these methodologies with insights into human behavioral patterns, particularly in terms of dealing with uncertainties in win probabilities, the aversion to losses, and the valuation of growth. Our findings indicate that the Justus Criterion presents a pragmatic, user-friendly strategy for trading that resonates with empirical data and the intrinsic risk preferences of traders, offering a comprehensive model for enhanced decision-making in financial markets.

Upper and lower bounds for singularly perturbed linear quadratic optimal control problems
Creators: name: Howe, Sei
Publisher: name: Imperial College London
Year: 2017

description: The question of how to optimally control a large scale system is widely considered to be difficult to solve due to the size of the problem. This difficulty is further compounded when a system exhibits a two time-scale structure where some components evolve slowly and others evolve quickly. When this occurs, the optimal control problem is regarded as singularly perturbed with a perturbation parameter epsilon representing the ratio of the slow time-scale to the fast time-scale. As epsilon goes to zero, the system becomes stiff resulting in a computationally intractable problem. In this thesis, we propose an analytic method for constructing bounds on the minimum cost of a singularly perturbed, linear-quadratic optimal control problem that hold for any arbitrary value of epsilon.

description: We study the propagation and injection models of cosmic rays using the latest measurements of the Boron-to-Carbon ratio and fluxes of protons, Helium, Carbon, and Oxygen nuclei by the Alpha Magnetic Spectrometer and the Advanced Composition Explorer at top of the Earth, and the Voyager spacecraft outside the heliosphere. The ACE data during the same time interval of the AMS-02 data are extracted to minimize the complexity of the solar modulation effect. We find that the cosmic ray nucleus data favor a modified version of the diffusion-reacceleration scenario of the propagation. The diffusion coefficient is, however, required to increase moderately with decreasing rigidity at low energies, which has interesting implications on the particle and plasma interaction in the Milky Way. We further find that the low rigidity ($

description: The quasar Q1208+1011 (z_{em}=3.8) is the second highest redshift double quasar ever detected. Several indications point toward it being a gravitational lensed system, although a definitive proof is still lacking. We present new evidence of its lensed nature based on the weakness of the ``proximity effect'' measured in the high resolution Lyman absorption spectrum of the QSO. A luminosity amplification as large as 22 has been derived from this analysis. Indications on the redshift of the lensing galaxy can be obtained from the analysis of the intervening heavy element absorption systems discovered in the QSO high resolution spectrum. On statistical and dynamical grounds a MgII system present at z=1.13 appears as the most likely candidate for the lensing galaxy. We compare the observed parameters with a simple isothermal model for the lens to derive the properties of the lensing galaxy. The resulting magnification factor is smaller, although marginally consistent with that derived by the analysis of the proximity effect.

description: Memory and network bandwidth are decisive bottlenecks when handling high-resolution multidimensional data sets in visualization applications, and they increasingly demand suitable data compression strategies. We introduce a novel lossy compression algorithm for multidimensional data over regular grids. It leverages the higher-order singular value decomposition (HOSVD), a generalization of the SVD to three dimensions and higher, together with bit-plane, run-length and arithmetic coding to compress the HOSVD transform coefficients. Our scheme degrades the data particularly smoothly and achieves lower mean squared error than other state-of-the-art algorithms at low-to-medium bit rates, as it is required in data archiving and management for visualization purposes. Further advantages of the proposed algorithm include very fine bit rate selection granularity and the ability to manipulate data at very small cost in the compression domain, for example to reconstruct filtered and/or subsampled versions of all (or selected parts) of the data set.

description: A large and sparse random graph with independent exponentially distributed link weights can be used to model the propagation of messages or diseases in a network with an unknown connectivity structure. In this article we study an extended setting where also the nodes of the graph are equipped with nonnegative random weights which are used to model the effect of boundary delays across paths in the network. Our main results provide approximative formulas for typical first passage times, typical flooding times, and maximum flooding times in the extended setting, over a time scale logarithmic with respect to the network size.

description: We study on which compact Sasakian 3-manifolds the Reeb field, which is a Beltrami field with eigenvalue 2, is an energy minimizer in its adjoint orbit under the action of volume preserving diffeomorphisms. This minimization property for Beltrami fields is relevant because of its connections with the phenomenon of magnetic relaxation and the hydrodynamic stability of steady Euler flows. We characterize the Sasakian manifolds where the Reeb field is a minimizer in terms of the first positive eigenvalue of the curl operator and show that for $a>a_0$ (a constant that depends on the Sasakian structure) the Reeb field of the $\mathcal{D}$-homothetic deformation of the manifold with constant $a$ (which is still Sasakian) is an unstable critical point of the energy, and hence not even a local minimizer. We also provide some examples of Sasakian manifolds where the Reeb field is a minimizer, highlighting the case of the weighted 3-spheres, on which another minimization problem (for the quartic Skyrme-Faddeev energy) is shown to admit exact solutions.

description: Strong mass loss on the red giant branch (RGB) can result in the formation of extreme horizontal branch (EHB) stars. The EHB stars spend most of their He core and shell burning phase at high temperatures and produce copious ultraviolet flux. They have very small hydrogen envelopes and occupy a small range in mass. We have computed evolutionary RGB models with mass loss for stars with a range of metallicities at initial masses < 1.1 Msun corresponding to populations ages between 12.5 and 14.5 Gyr. We used the Reimers formula to characterize mass loss, but investigated a larger range of the mass loss efficiency parameter, eta, than is common. To understand how the number of EHB stars varies with metallicity in a stellar population we considered how the zero-age horizontal branch (ZAHB) is populated. The range in eta producing EHB stars is comparable to that producing `mid-HB' stars. Somewhat surprisingly, neither the range nor magnitude of eta producing EHB stars varies much metallicity. In contrast, the range of eta producing mid-HB stars decreases with increasing metallicity. Hence the HB of populations with solar metallicity and higher, such as expected in elliptical galaxies and spiral bulges, will be bimodal if the distribution covers a sufficiently large range in eta.

Constraints on galaxy formation from alpha-enhancement in luminous elliptical galaxies

description: We explore the formation of alpha-enhanced and metal-rich stellar populations in the nuclei of luminous ellipticals under the assumption of two extreme galaxy formation scenarios based on hierarchical clustering, namely a fast clumpy collapse and the merger of two spirals. We investigate the parameter space of star formation time-scale, IMF slope, and stellar yields. In particular, the latter add a huge uncertainty in constraining time-scales and IMF slopes. We find that -- for Thielemann, Nomoto & Hashimoto nucleosynthesis -- in a fast clumpy collapse scenario an [alpha/Fe] overabundance of approx. 0.2 dex in the high metallicity stars can be achieved with a Salpeter IMF and star formation time-scales of the order 10^9 yr. The scenario of two merging spirals which are similar to our Galaxy, instead, fails to reproduce alpha-enhanced abundance ratios in the metal-rich stars, unless the IMF is flattened during the burst ignited by the merger. This result is independent of the burst time-scale. We suggest that abundance gradients give hints to distinguish between the two extreme formation scenarios considered in this paper.

description: We present a new method for calculating the merger history of matter halos in hierarchical clustering cosmologies. The linear density field is smoothed on a range of scales, these are then ordered in decreasing density and a merger tree constructed. The method is similar in many respects to the block model of Cole \& Kaiser but has a number of advantages: (i) it retains information about the spatial correlations between halos, (ii) it uses a series of overlapping grids and is thereby much better at finding rare, high-mass halos, (iii) it is not limited to halos whose mass ratios are powers of two, and (iv) it is based on an actual realization of the density field and so can be tested against N-body simulations. The major disadvantages are (i) the minimum halo mass is eight times the unit cell with a corresponding loss of dynamic range, and (ii) occasionally the relative location of halos in the tree does not reflect the correct ordering of their collapse times, as computed from the mean halo density. We show that our model exhibits the required scaling behaviour when tested on power-law spectra of density perturbations, but that it predicts far more massive halos than does the Press-Schechter formalism for flat spectra. We suggest reasons why this should be so.

The Chelsea Critical Care Physical Assessment tool (CPAx): validation and evaluation into the impact of a daily bedside scoring system which grades physical recovery from critical illness.
Creators: name: Corner, Evelyn
Publisher: name: Imperial College London
Year: 2017

description: Muscle wasting is a common consequence of critical illness, leading to long-term physical morbidity. Early rehabilitation in the Critical Care Unit (CCU) is now the norm. Guidelines suggest that this rehabilitation should be goal-directed and based on comprehensive assessment of physical function, however there was no tool to assess physical function objectively. The aim was to evaluate the clinimetric properties of the Chelsea Critical Care Physical Assessment tool (CPAx); a tool designed to measure function in critical illness objectively; to explore the patient experience of the CPAx in early rehabilitation, and; to use the CPAx to evaluate common recovery trajectories. This was a convergent mixed methods study. Preparatory work included integration of the CPAx into clinical practice, allowing recording of daily CPAx. Observational cohort studies were completed to determine the validity, responsiveness, and floor/ceiling effect of the CPAx. The database was also used to explore daily functional recovery and to establish the minimal detectable change (MDC) of the CPAx. An eLearning module to teach clinicians how to use the CPAx was developed and distributed with evaluative questionnaires to determine the CPAx’s content validity. Case studies were embedded in the module for inter-rater reliability testing. Grounded-theory methodology with semi-structured interviews was used to explore the patient experience of the CPAx tool in early rehabilitation. The results showed that the CPAx is valid, reliable, responsive, and widely used; however, it is likely to have a ceiling effect after hospital discharge. The CPAx may have a role in goal setting for long-stay patients and help to fill in loss of life narrative after critical illness; however the CPAx is difficult to comprehend in the early days of CCU, which are overshadowed by delirium, sleep deprivation and fatigue. Function and CCU length of stay are closely associated, suggesting that function may influence length of stay.

description: The three-site Pati-Salam gauge model provides a consistent description for the hints of lepton-flavor non-universality observed in $B$ decays, connecting the present pattern of "anomalies" to the origin of the Standard Model Yukawa couplings. We present here a detailed analysis of the model predictions for a series of low-energy observables, mainly in $B$ and $τ$ physics. The model is in good agreement with present data and predicts a well-defined pattern of non-standard effects in low-energy observables that could allow us to test it in the near future. Particularly interesting are the predictions of large $τ\toμ$ Lepton Flavor Violating processes, such as $τ\to μγ$, $τ\to 3μ$, $B\to K τμ$, and $B_s\toτμ$. Also $μ\to 3 e$, $μ\to eγ$, and $K_L \to μe$ decays could be not far from the present exclusion bounds, although this conclusion is more model dependent.

 2. Purely thermodynamic considerations show that strong erasure cannot be dissipationless.
 3. The main source of entropy creation in erasure processes at molecular scales is the entropy that must be created to suppress thermal fluctuations ("noise").
 4. A phase space analysis recovers no minimum entropy cost for weak erasure and a positive minimum entropy cost for strong erasure.
 5. An information entropy term has been attributed mistakenly to pre-erasure states in the Gibbs formalism through the neglect of an additive constant in the "-k sum p log p" Gibbs entropy formula.

Our sample of Virgo galaxies ranges from H I deficient objects near the core of the cluster to galaxies with normal H I properties, far from the cluster core. We investigate the relationship between H I disk characteristics and chemical abundances to determine whether dynamical process that remove gas from the disk, such as ram pressure stripping by the intracluster medium, also affect the chemical abundances.

description: In recent years, more and more attention has been paid to the use of artificial neural networks (ANN) for diagnostics of gas pumping units (GPU). Usually, ANN training is carried out on models of GPU workflows, and generated sets of diagnostic data are used to simulate defect conditions. At the same time, the results obtained do not allow assessing the real state of the GPU. It is proposed to use the values of the characteristics of the acoustic and vibration processes of the GPU as the input data of the ANN. A descriptive statistical analysis of real vibration and acoustic processes generated by the operation of the GPU type GTK-25-i (Nuovo Pignone, Italy) has been carried out. The formation of packets of diagnostic signs arriving at the input of the ANN has been carried out. The diagnostic features are the five maximum amplitude components of the acoustic and vibration signals, as well as the value of the standard deviation for each sample. Diagnostic signs are calculated directly in the input pipeline of ANN data in real time for three technical states of the GPU. Using the frameworks TensorFlow, Keras, NumPy, pandas, in the Python 3 programming language, an architecture was developed for a deep fully connected feedforward ANN, training on the error backpropagation algorithm. The results of training and testing of the developed ANN are presented. During testing, it was found that the signal classification precision for the "nominal" state of all 1475 signal samples is 1.0000, for the "current" state, precision equils 0.9853, and for the "defective" state, precision is 0.9091. The use of the developed ANN makes it possible to classify the technical states of the GPU with an accuracy sufficient for practical use, which will prevent the occurrence of GPU failures. ANN can be used to diagnose GPU of any type and power.

description: Coarse building mass models are now routinely generated at scales ranging from individual buildings through to whole cities. For example, they can be abstracted from raw measurements, generated procedurally, or created manually. However, these models typically lack any meaningful semantic or texture details, making them unsuitable for direct display. We introduce the problem of automatically and realistically decorating such models by adding semantically consistent geometric details and textures. Building on the recent success of generative adversarial networks (GANs), we propose FrankenGAN, a cascade of GANs to create plausible details across multiple scales over large neighborhoods. The various GANs are synchronized to produce consistent style distributions over buildings and neighborhoods. We provide the user with direct control over the variability of the output. We allow her to interactively specify style via images and manipulate style-adapted sliders to control style variability. We demonstrate our system on several large-scale examples. The generated outputs are qualitatively evaluated via a set of user studies and are found to be realistic, semantically-plausible, and style-consistent.

Diagnosing cancer one cell at a time with single molecule spectroscopy

Publisher: name: Imperial College London

description: Mapping protein expression heterogeneity in cancer at single cell resolution is essential for the understanding of disease progression, emergent drug resistance, and metastasis, but is a great technical challenge. Longitudinal monitoring of heterogeneity pertaining to biomarker expression may provide the necessary medical cues for the administering of personalised therapeutics. Studying molecular heterogeneity in the ultra-rare circulating tumour cells [CTCs] found in the blood of cancer patients is a greater challenge still, but success may yield deep insight into the nature of the metastatic cascade, and also provide the technologi-cal means of a non-invasive ‘liquid biopsy’. The MAC chip is a quantitative single molecule sensitive protein assay for the evalua-tion of protein copy number in single cells. In this thesis, we attempt the development of a new biomarker-targeting MAC chip assay for the breast cancer oncoprotein estrogen recep-tor alpha. We describe a series of improvements to the MAC chip assay architecture allow-ing multiplexed measurement of several proteins simultaneously, and improvements to analysis methods allowing for superior molecule counting. Building on the work of others in the field of circulating tumour cell isolation, we attempt the integration of the MAC chip analysis method into a multiple-stage device for the isolation and proteomic analysis of cir-culating tumour cells. Finally, using a multiplexed MAC chip device for the tumour sup-pressor protein p53 and its activated form phosphorylated at serine-15, we demonstrate for the first time that the MAC chip can be used to study protein expression heterogeneity in quasi-clinical samples. The patient-derived xenografts we use to perform this work are a key resource of clinically-relevant tumour material, and a model system directly analogous to primary patient biopsies, thus demonstrating the feasibility of translational single cell pro-teomics with the MAC chip system.

description: Recently we have introduced a nonrelativistic cosmological model (NRCM) exhibiting a dynamical spatial curvature. For this model the present day cosmic acceleration is not attributed to a negative pressure (dark energy) but it is driven by a nontrivial energy flow leading to a negative spatial curvature. In this paper we generalize the NRCM in two different ways to the relativistic regime and present analytical solutions of the corresponding Einstein equations. These relativistic models are characterized by two inequivalent extensions of the FLWR metric with a time-dependent curvature function $K (t)$ and an expansion scalar $a(t)$. The fluid flow is supposed to be geodesic. The model V1 is shear-free with isotropic pressure and therefore conformal flat. In contrast to V1 the second model V2 shows a nontrivial shear and an anisotropic pressure. For both models the inhomogeneous solutions of the corresponding Einstein equations will agree in leading order at small distances with the NRCM if a(t) and K(t) are each identical with those determined in the NCRM. Then the metric is completely fixed by three constants. The arising energy momentum tensor contains a nontrivial energy flow vector. Our models violate locally the weak energy condition. Global volume averaging leads to explicit expressions for the effective scale factor and the expansion rate $H (z)$. Backreaction effects cancel each other for the model V2 but they are nonzero and proportional to the square of the magnitude of the energy flow for the model V1. The large scale (relativistic) corrections to the NCRM results are small for the model V2 for a small-sized energy flow. We have reproduced a corresponding adjustment of the three free constants from [1] to cosmic chronometer data leading to the prediction of an almost constant, negative value for the dimensionless curvature function $k(z) \sim - 1$ for redshifts $z < 2$.

PEDOT:PSS-based hybrid materials for optoelectronics applications

description: Organic electronics is a research area that, in recent year, has received increasing attention both from academia and industry. Performance of organic optoelectronic devices, such as organic light-emitting diodes (OLEDs) and organic photovoltaic devices (OPVs), relies on the electrical and optical characteristics of each component. However, the performance are frequently limited by the distribution of the internal electromagnetic field: an effective light management, involving either the incoupling of incident radiation (in case of photovoltaic cells and photo-detectors), or the outcoupling of emitted light (for light-emitting diodes), is crucial. The electric field distribution may be optimised by adjusting the device geometry or, alternatively, by modifying the optical properties (i.e. refractive index and absorption coefficient) of each component. Developing a material with tunable optical properties, whilst maintaining acceptable electrical characteristics, would offer a significant alternative in high-performance devices. Among the different compounds used in organic devices, the charge injection/extraction materials play a key role: the ubiquitous poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) is an example of an organic compound often limited (in thickness) by the optical losses. In this work we introduce an innovative, solution-processable, inorganic/organic hybrid material based on PEDOT:PSS, which could be used as an efficient hole-transport layer, or as an electrode, in OLEDs and OPVs. The hybrid system exhibits high optical quality, a dramatic increase of refractive index (up to +12-13%), and a decrease in work function, whilst maintaining good electrical conductivity. We prove the effectiveness of our approach both by modeling the distribution of normalised modulus squared of the optical electric field in light-emitting structures. Furthermore, we fabricate and characterise optoelectronic devices (OLEDs and OPVs) with PEDOT:PSS hybrid hole-transport layers, demonstrating an increase of efficiency in the organic light-emitting diodes. Finally, we investigate the thermoelectric properties of hybrid material, thus opening interesting new applications for our hybrid compound.

description: We have analysed the observable consequences of the interactions of spin-1 resonances coupled to the invariant fermionic currents that arise in an $SO(5)$ Composite Higgs set-up. The phenomenology entailed by such interactions is thoroughly analysed by studying heavy vector resonances production and decay modes in the viable resonance mass range. Additionally, the production of double and single-composite fermion final states has been scanned along the fermion mass scale. Such production is mediated by the SM gauge and Higgs interactions, and also by charged and neutral vector resonances. The coupling between the new fermions and vector resonances induces a sizeable effect in the production rates. We use the recent 13 TeV LHC searches for vector-like quarks to constrain our parameter space. Specifically, we explore the allowed regions by analysing the decays of a heavy vector-like quark in the $Wb$-channel. We conclude that generically the impact of the couplings between the spin-1 and spin-1/2 resonances will substantially reduce the permitted regions, leading us to test the sensitivity of the parametric dependence in the light of exotic matter interactions.

Understanding the potential mechanisms of action of dietary prostate carcinogens

Publisher: name: Imperial College London

description: Prostate cancer is the most commonly diagnosed cancer in males in the UK, and while the precise aetiology of prostate cancer remains unknown, risk factors such as age and lifestyle have been identified. Consumption of a ‘western’ diet rich in well-done red meat has been implicated in the development of prostate cancer, due to the appreciable amounts of carcinogenic material found in these foods. Two common dietary carcinogens are benzo[a]pyrene (B[a]P) and 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), both of which have been identified as possible prostate mutagens. Another possible risk factor for prostate cancer is inflammation (a common condition in the prostate), specifically interleukin- 6 (IL-6) which is found elevated in the serum of prostate cancer patients. The underlying mechanisms behind the influence of dietary carcinogens and inflammation on the development of prostate cancer remain elusive, with limited knowledge about how inflammation may alter the modes of action of dietary carcinogens in the prostate. I hypothesised that IL-6 may alter the activation of B[a]P and PhIP, resulting in phenotypic alterations to prostate cells that are associated with cancer development. Using an in vitro, cell culture based model, the current project reported findings that both B[a]P and PhIP induce alterations in prostate cell migration while demonstrating genotoxic potential. Moreover, mixtures of B[a]P and PhIP induced significantly more genetic damage than either chemical in isolation, suggesting that interplay during simultaneous exposure in vivo may result in higher levels of DNA damage in the prostate. Further, PhIP-induced genotoxicity appeared to be a result of cytochrome P450-mediated production of reactive oxygen species. Finally, my data indicate that IL-6 increases B[a]P-mediated genetic damage, suggesting that activation of B[a]P in prostate cells may be altered by inflammatory cytokines such as IL-6, but more work is needed in order to verify this interaction. These novel findings must be explored in greater depth in order to fully understand how these factors interact in the prostate.

description: This paper addresses the challenge of integrating semantic communication principles into operated networks, traditionally optimized based on network-centric metrics rather than application-specific needs. Operated networks strongly adhere to the principle of ``separation of concerns", which emphasizes a clear distinction between network operation and application. Despite the initial perceived incompatibility between semantic communication and the principles of operated networks, this paper provides solutions to reconcile them. The foundations of these solutions include the adoption of non-arbitrary semantic representations as a standard encoding for communications, the establishment of a standard interface between the application and network, and a dedicated network control plane. These enable the application to describe the data typology and the nature of the task, and to agree upon a transmission scheme tailored to the supported task. Through three scenarios involving an application transmitting text representations, we illustrate the implementation of the proposal and demonstrate the potential of the approach.

A total variation approach to sampling and sparse reconstruction from Fourier measurements

description: Inferring the fine scale properties of a signal from its coarse measurements is a common signal processing problem that finds a myriad of applications in various areas of experimental sciences. Line spectral estimation is probably one of the most iconic instances of this category of problems and consists of recovering the locations of highly localized patterns, or spikes, in the spectrum of a time signal by observing a finite number of its uniform samples. Recent advances have shown that convex programming could be used to estimate the frequency components of a spectrally sparse signal. This thesis focuses on the total variation (TV) approach to perform this reconstruction. It is conjectured that a phase transition on the success of the total variation regularization occurs whenever the distance between the spectral components of the signal to estimate crosses a critical threshold. We prove the necessity part of this conjecture by demonstrating that TV regularization can fail bellow this limit. In addition, we enrich the sufficiency side by proposing a novel construction of a dual certificate built on top of a so-called diagonalizing basis which can guarantee a prefect reconstruction of the spectrum up to near optimal regimes. Moreover, we study the computational cost of the TV regularization, which remains the major bottleneck to its application to practical systems. A low-dimensional semidefinite program is formulated and its equivalence with the TV approach is ensured under the existence of a certain trigonometric certificate verifying the sparse Fejér-Riesz condition, leading to potential order of magnitude changes in the computational complexity of the algorithm. This low dimensional algorithm is then applied in the context of multirate sampling systems in order to jointly estimate sparse spectra at the output of several samplers. We demonstrate the sub-Nyquist capabilities and the high computational efficiency of such systems.
