description: From an information theoretic perspective, joint communication and sensing (JCAS) represents a natural generalization of communication network functionality. However, it requires the re-evaluation of network performance from a multi-objective perspective. We develop a novel mathematical framework for characterizing the sensing and communication coverage probability and ergodic rate in JCAS networks. We employ a formulation of sensing parameter estimation based on mutual information to extend the notions of coverage probability and ergodic rate to the radar setting. We define sensing coverage probability as the probability that the rate of information extracted about the parameters of interest associated with a typical radar target exceeds some threshold, and sensing ergodic rate as the spatial average of the aforementioned rate of information. Using this framework, we analyze the downlink sensing and communication coverage and rate of a mmWave JCAS network employing a shared waveform, directional beamforming, and monostatic sensing. Leveraging tools from stochastic geometry, we derive upper and lower bounds for these quantities. We also develop several general technical results including: i) a generic method for obtaining closed form upper and lower bounds on the Laplace Transform of a shot noise process, ii) a new analog of H{ö}lder's Inequality to the setting of harmonic means, and iii) a relation between the Laplace and Mellin Transforms of a non-negative random variable. We use the derived bounds to numerically investigate the performance of JCAS networks under varying base station and blockage density. Among several insights, our numerical analysis indicates that network densification improves sensing SINR performance -- in contrast to communications.

description: The increasing intensification of dairy farming in Europe has sparked an interest in studying the economic consequences of this process. However, empirically classifying farms as extensive or intensive is not a straightforward task. In recent papers, Latent Class Models (LCM) have been used to avoid an ad-hoc split of the sample into intensive and extensive dairy farms. A limitation of current specifications of LCM is that they do not allow farms to switch between different productive systems over time. This feature of the model is at odds with the process of intensification of the European dairy industry in recent decades. We allow for changes of production system over time by estimating a single LCM model but splitting the original panel into two periods, and find that the probability of using the intensive technology increases over time. Our estimation proposal opens up the possibility of studying the effects of intensification not only across farms but also over time.

description: I critique a recent analysis (Miles, Stedman & Heald, 2020) of COVID-19 lockdown costs and benefits, focussing on the United Kingdom (UK). Miles et al. (2020) argue that the March-June UK lockdown was more costly than the benefit of lives saved, evaluated using the NICE threshold of £30000 for a quality-adjusted life year (QALY) and that the costs of a lockdown for 13 weeks from mid-June would be vastly greater than any plausible estimate of the benefits, even if easing produced a second infection wave causing over 7000 deaths weekly by mid-September. I note here two key problems that significantly affect their estimates and cast doubt on their conclusions. Firstly, their calculations arbitrarily cut off after 13 weeks, without costing the epidemic end state. That is, they assume indifference between mid-September states of 13 or 7500 weekly deaths and corresponding infection rates. This seems indefensible unless one assumes that (a) there is little chance of any effective vaccine or improved medical or social interventions for the foreseeable future, (b) notwithstanding temporary lockdowns, COVID-19 will very likely propagate until herd immunity. Even under these assumptions it is very questionable. Secondly, they ignore the costs of serious illness, possible long-term lowering of life quality and expectancy for survivors. These are uncertain, but plausibly at least as large as the costs in deaths. In summary, policy on tackling COVID-19 cannot be rationally made without estimating probabilities of future medical interventions and long-term illness costs. More work on modelling these uncertainties is urgently needed.

description: The food sector has traditionally been considered one with the lowest research and development expenditure to value added ratio. In recent decades, however, the business environment has become more demanding in terms of technological inputs for reasons related to food safety, quality and also the globalisation of the food market. This provides a strong incentive to innovate, especially for small and mediumsized enterprises (SME) seeking to remain in business. Most businesses operating in the food sector belong to the SME category which, based on the literature, tends to have a low level of research capacity. This study seeks to identify determinants of the types of innovation adopted and associations between them by analysing a sample of European food SMEs. For this purpose a non-parametric analysis, namely the classification tree technique, is carried out. The main finding is that due to the technological factors inherent in the food industry, a tight linkage exists between product, process and market innovation. Moreover, the study shows that collaboration between competitors encourages SMEs to engage in market, process and business model innovation. Conversely, synergy with suppliers and customers supports product innovation.

description: Locarno liegt am nördlichen Ufer des Lago Maggiores im Schweizer Kanton Tessin, ein Kanton mit dicht bebauten Talsohlen vorwiegend um die Städte Chiasso, Bellinzona Mendrisio Lugano und eben Locarno. Seit längerem gibt es das Bestreben den gesamten Kanton als zusammenhängende, großstädtische Landschaft mit verstreuten urbanen Polen zu organisieren, der sogenannten 'Città Ticino', in der neben diversen Verkehrsentwicklungsprojekten auch die Stärkung der kulturellen Infrastruktur der Ballungzentren hohe Priorität hat. Einen dieser urbanen Pole bildet das Gebiet um den Kopfbahnhof in Locarno, einer Stadt die sich im Zuge des Konzeptes der vernetzten Stadt auf seine kulturelle Ausrichtung festlegen will. Seitens der Stadt besteht großes Interesse auf diesem Areal ein Kongresszentrum zu errichten, das im alltäglichen Gebrauch als Erweiterung des kleinen, bestehenden Kongresssaals in Muralto funktionieren soll, jedoch aber auch einen idealen Rahmen für das dort jährlich stattfindende Filmfestival bieten würde. Mit dem 'Forum Locarno' bestehend aus dem neuen Kongresshaus, einer Bibliothek, eine Kunsthalle, einem Pavillon, der das kulinarische Angebot abdeckt, wird ein städtisches Ensemble geschaffen, das über die Grenzen Locarnos hinaus im großmaßstäblichen Gedanken der Città Ticino funktioniert.
description: Locarno is located at the north bank of the Lago Maggiore in the Swiss district Tessin. It is a district - so called 'Kanton' - with densely populated valleys mainly around the city areas of Chiasso, Bellinzona Mendrisio Lugano und also Locarno. For a while there has been interest and initiative to organize the whole Kanton as a connected, metropolitan area with grouped urban nodes called 'Città Ticino' where, alongside with transport development projects, the aim is to strengthen the cultural infrastructure particularly in the urban centres. The area of the terminus station in Loncarno forms one of these urban nodes, a city that is striving to build up its cultural focus and direction within this concept. The city shows great interest in constructing a congress centre in that area, which shall on a daily basis function as a supplement to the small, available congress hall in Muralto and furthermore provide an excellent venue for the annual film festival. The so-called 'Forum Locarno' will consist of a new congress centre, a library, an exhibition hall and a pavilion that will be offering a wide culinary range. This ensemble of buildings will eventually serve as a driving force within the large-scale approach of the 'Città Ticino'.

description: The aim of the paper is to highlight the positioning of the so-called Made in Italy agro-food exports in foreign markets considering global world tendencies as well as country specific trends. Besides, we aim at disentangling the role of product quality from price competition as a driver of competitive advantages. To these ends, the work combines two different methodologies, applied in three steps. First, we estimate the elasticities of Italian exports, with respect to world imports, Italian export prices and the competitors’ prices. Second, an index of the sophistication of exports’ flows that captures the role of quality in global competition is calculated. Third, the estimated elasticities are compared with the changes in the sophistication levels. Results allow for product-specific trends to stem out from the overall picture. Exports’ performance varies according to the type of product and to the degree of market completion. Although, the Made In Italy aggregate seems overall competitive, the analysis pinpoints some drawbacks in the positioning of some products in the world arena. Focus on wine and on olive oil, two major Italian exporting sectors, helps in understanding the potential of the joint methodology adopted.

description: Based on first-principles calculations we show that gold atoms can form both free-standing and tip-suspended chiral single-wall nanotubes composed of helical atomic strands. Free-standing, infinite (5,5) tube is found to be energetically the most favorable. While energetically less favorable, the experimentally observed (5,3) tube stretching between two tips corresponds to a local minimum in the string tension. Similarly, the (4,3) tube is predicted as a favorable structure yet to be observed experimentally. Analysis of band structure, charge density, and quantum ballistic conductance suggests that the current on these wires is less chiral than expected, and there is no direct correlation between the numbers of conduction channels and helical strands.

description: This report discusses recent results as well as new perspectives in the ergodic theory for Riemann surface laminations, with an emphasis on singular holomorphic foliations by curves. The central notions of these developments are leafwise Poincaré metric, directed positive harmonic currents, multiplicative cocycles and Lyapunov exponents. We deal with various ergodic theorems for such laminations: Random and Operator Ergodic Theorems, (Geometric) Birkhoff Ergodic Theorems, Oseledec Multiplicative Ergodic Theorem and Unique Ergodicity Theorems. Applications of these theorems are also given. In particular, we define and study the canonical Lyapunov exponents for a large family of singular holomorphic foliations on compact projective surfaces. Topological and algebro-geometric interpretations of these characteristic numbers are also treated. These results highlight the strong similarity as well as the fundamental differences between the ergodic theory of maps and that of Riemann surface laminations. Most of the results reported here are known. However, sufficient conditions for abstract heat diffusions to coincide with the leafwise heat diffusions (Subsection 5.2) are new ones.

Inequality in British Columbia : what role does tax policy play?
Creators: name: Wallis, Kimberly Dawn
Publisher: name: University of British Columbia
Year: 2010

description: In 2001 a new provincial government was elected in the province of British Columbia, the BC Liberal party. During their election campaign they promised that lower personal income taxes would stoke the BC economy. Although personal income taxes were lowered after their election, high income earners were given a much higher proportion of the tax cut (when looked at as a dollar value per person) than middle and lower income earners. Further, since government service fees increased in many areas, it is possible that middle and lower income earners may have found themselves paying more to the government in combined taxes and fees than before the advertised tax cuts. It is thus more realistic to suggest that the burden of taxes has shifted rather than to say that taxes were cut. Social services were also cut dramatically. It is suggested that inequality is likely to increase in the province as a result of these changes. The question of whether the changes to the personal income tax rates will have a positive effect on the BC economy, both in the short, medium and long term is considered. In the short term, it is questionable whether reducing personal income taxes will provide any stimulus to such component parts of the economy as the supply of labour and the supply of capital. It is noted that productivity, a key indicator that the BC Liberals sought to alter through changes to personal income taxes, has not improved. In the long term, a decreased investment in such social services as health and education may have a negative effect on the rate of economic growth in the province.
Relativistic time-of-arrival measurements: predictions, post-selection and causality problem

description: We analyze time-of-arrival probability distributions for relativistic particles in the context of quantum field theory (QFT). We show that QFT leads to a unique prediction, modulo post-selection that incorporates properties of the apparatus into the initial state. We also show that an experimental distinction of different probability assigments is possible especially in near-field measurements. We also analyze causality in relativistic measurements. We consider a quantum state obtained by a spacetime-localized operation on the vacuum, and we show that detection probabilities are typically characterized by small transient non-causal terms. We explain that these terms originate from Feynman-propagation of the initial operation, because the Feynman propagator does not vanish outside the light-cone. We discuss possible ways to restore causality, and we argue that this may not be possible in measurement models that involve switching the field-apparatus coupling on and off.

description: We investigate the phenomenology of nonlinear Compton scattering of polarised photons by unpolarised electrons in plane-wave backgrounds. The energy and angular spectra of polarised photons are calculated for linearly- and circularly-polarised pulses, monochromatic fields and constant crossed field backgrounds. When the field intensity is in the weakly nonlinear regime, photons in different polarisation states are predicted to possess very different energy and angular distributions. We explain this difference by calculating the spectrum for nonlinear Thomson scattering in a linearly-polarised monochromatic background and projecting the electron's trajectory onto the different polarisation directions. Finally, we calculate a scenario for multi-GeV electrons and by considering the energy and angular-resolved photon polarisation purity, find one can achieve a GeV-photon beam with polarisation purities of over $90\%$.

description: Thin films of Ti1-xFexO2 (x=0 and 0.05) have been prepared on sapphire substrates by spin-on technique starting from metal organic precursors. When heat treated in air at 550 and 700 degrees C respectively, these films present pure anatase and rutile structures as shown both by X-ray diffraction and Raman spectroscopy. Optical absorption indicate a high degree of transparency in the visible region. Such films show a very small magnetic moment at 300 K. However, when the anatase and the rutile films are annealed in a vacuum of 1x10-5 Torr at 500 degrees C and 600 degrees C respectively, the magnetic moment, at 300 K, is strongly enhanced reaching 0.46 $μ$B/Fe for the anatase sample and 0.48 $μ$B/Fe for the rutile one. The ferromagnetic Curie temperature of these samples is above 350 K.

description: Radio relics trace shock fronts generated in the intracluster medium (ICM) during cluster mergers. The particle acceleration mechanism at the shock fronts is not yet completely understood. We observed the Toothbrush relic with the Effelsberg and Sardinia Radio Telescope at 14.25 GHz and 18.6 GHz, respectively. Unlike previously claimed, the integrated spectrum of the relic closely follows a power law over almost three orders of magnitude in frequency, with a spectral index of $α_{\rm 58\,MHz}^{\rm 18.6\,GHz}=-1.16\pm0.03$. Our finding is consistent with a power-law injection spectrum, as predicted by diffusive shock acceleration theory. The result suggests that there is only little magnetic field strength evolution downstream to the shock. From the lack of spectral steepening, we find that either the Sunyaev-Zeldovich decrement produced by the pressure jump is less extended than $\sim$ 600\,kpc along the line of sight or, conversely, that the relic is located far behind in the cluster. For the first time, we detect linearly polarized emission from the "brush" at 18.6 GHz. Compared to 8.3 GHz, the degree of polarization across the brush increases at 18.6 GHz, suggesting a strong Faraday depolarization towards lower frequencies. The observed depolarization is consistent with an intervening magnetized screen that arise from the dense ICM containing turbulent magnetic fields. The depolarization, corresponding to a standard deviation of the Rotation Measures as high as $σ_{\rm RM}= 212\pm23\rm \,rad\,m^{-2}$, suggests that the brush is located in or behind the ICM. Our findings indicate that the Toothbrush can be consistently explained by the standard scenario for relic formation

description: We present the first results of a photometric survey of poorly studied nova remnants in the Northern Hemisphere. The main results are as follows: DM Gem shows a modulation at 0.123 d (probably linked to the orbit) and rapid variations at ~22 min. A moderate resolution spectrum taken at the time of the photometric observations shows intense HeII 4686 and Bowen emission, characteristic of an intermediate polar or a SW Sex star. Variability at 0.127 d and intense flickering (or quasi-periodic oscillations) are the main features of the light curve of CP Lac. A 0.1-mag dip lasting for ~45 min is observed in GI Mon, which could be an eclipse. A clear modulation (probably related to the orbital motion) either at 0.179 d or 0.152 d is observed in the B-band light curve of V400 Per. The results for CT Ser point to an orbital period close to 0.16 d. Intense flickering is also characteristic of this old nova. Finally, XX Tau shows a possible periodic signal near 0.14 d and displays fast variability at ~24 min. Its brightness seems to be modulated at ~5 d. We relate this long periodicity to the motion of an eccentric/tilted accretion disc in the binary.

description: In high temperature cuprate superconductors, it was found that the superconducting transition temperature Tc depends on the number of CuO2 planes (n) in the structural unit and the maximum Tc is realized in the trilayer system (n=3). It was also found that the trilayer superconductors exhibit an unusual phase diagram that Tc keeps nearly constant in the overdoped region which is in strong contrast to the Tc decrease usually found in other cuprate superconductors. The electronic origin of the Tc maximization in the trilayer superconductors and its high Tc persistence in the overdoped region remains unclear. By taking high resolution laser-based angle resolved photoemission (ARPES) measurements, here we report our revelation of the microscopic origin of the unusual superconducting properties in the trilayer superconductors. For the first time we have observed the trilayer splitting in Bi2Sr2Ca2Cu3O10+d (Bi2223) superconductor. The observed Fermi surface, band structures, superconducting gap and the selective Bogoliubov band hybridizations can be well described by a three-layer interaction model. Quantitative information of the microscopic processes involving intra- and interlayer hoppings and pairings are extracted. The electronic origin of the maximum Tc in Bi2223 and the persistence of the high Tc in the overdoped region is revealed. These results provide key insights in understanding high Tc superconductivity and pave a way to further enhance Tc in the cuprate superconductors.

description: Recent research has made great progress in realizing neural style transfer of images, which denotes transforming an image to a desired style. Many users start to use their mobile phones to record their daily life, and then edit and share the captured images and videos with other users. However, directly applying existing style transfer approaches on videos, i.e., transferring the style of a video frame by frame, requires an extremely large amount of computation resources. It is still technically unaffordable to perform style transfer of videos on mobile phones. To address this challenge, we propose MVStylizer, an efficient edge-assisted photorealistic video style transfer system for mobile phones. Instead of performing stylization frame by frame, only key frames in the original video are processed by a pre-trained deep neural network (DNN) on edge servers, while the rest of stylized intermediate frames are generated by our designed optical-flow-based frame interpolation algorithm on mobile phones. A meta-smoothing module is also proposed to simultaneously upscale a stylized frame to arbitrary resolution and remove style transfer related distortions in these upscaled frames. In addition, for the sake of continuously enhancing the performance of the DNN model on the edge server, we adopt a federated learning scheme to keep retraining each DNN model on the edge server with collected data from mobile clients and syncing with a global DNN model on the cloud server. Such a scheme effectively leverages the diversity of collected data from various mobile clients and efficiently improves the system performance. Our experiments demonstrate that MVStylizer can generate stylized videos with an even better visual quality compared to the state-of-the-art method while achieving 75.5$\times$ speedup for 1920$\times$1080 videos.

description: Over the past two and half decades, much has been written about China's ongoing economic reforms. It is now widely accepted that China's current economic course has displaced Marxist-Leninist-Mao Zedong-Thought and, in the process, has served to undermine the ideological legitimacy of the regime. As a result, many commentators have spoken of the inevitable collapse of the Chinese Communist Party's (CCP) authoritarian hold of the country. However, far fewer questions have been asked about the degree to which the CCP may maintain control of the country by utilizing a byproduct of its economic exuberance, namely, law. Since the end of the Maoist era law has become a ubiquitous force in Chinese society, growing as both a condition precedent to and as a consequence of various development policies. This thesis examines the modern interplay of ideology and law in China in the context of international expectations, and the resulting challenges to the regime's legitimacy that arise directly from these tensions. By examining the manner in which the CCP is using law as a vehicle to entrench its long-term sustainability, this thesis attempts to explain how China's continued revolutionary trajectory is being pursued. I hold that paying attention to current developments and interpretations of law in China can have salutary benefits for other Sinologists whose perspectives stand outside of the legal realm.

description: We investigate the dynamical Casimir effect for a one-dimensional resonant cavity, with one oscillating mirror. Specifically, we study the discrete spectrum of created particles in a region of frequencies above the oscillation frequency $ω_0$ of the mirror. We focus our investigation on an oscillation time equal to $2L_0/c$, where $L_0$ is the initial and final length of the cavity, and $c$ is the speed of light. For this oscillation duration, a field mode, after perturbed by the moving mirror, never meets this mirror in motion again, which allows us to exclude this effect of re-interaction on the particle creation process. Then, we describe the evolution of the particle creation with frequencies above $ω_0$ only as a function of the relativistic aspect of the mirror's velocity. In other words, we analyze the formation of relativistic bands in a discrete spectrum of created particles.

description: The Barrow entropy appears from the fact that the black hole surface can be modified due to quantum gravitational outcome. The measure of this perturbation is given by a new exponent $Δ$. In this letter we have shown that, from the standard mathematical form of the equipartition theorem, we can relate it with Barrow entropy. From this equivalence, we have calculated precisely the value of the exponent for the equipartition law. After that, we tested the thermodynamical coherence of the system by calculating the heat capacity which established an interval of the possible thermodynamical coherent values of Barrow entropic exponent and corroborated our first result.

description: We have performed the bulk-sensitive high-resolution soft x-ray photoemission study of a Kondo semiconductor CeRhAs and related compounds CeNiSn and CePdSn. The comparison of the spectra of polycrystalline CePdSn on the fractured and scraped surfaces shows that the fracturing of the samples is much better than the scraping in order to obtain intrinsic photoemission spectra. The Ce 4d core-level spectra show clear differences in the electronic states among the materials.

Transport of quantum noise through random media

Subjects: subject: Quantum Physics (quant-ph)

description: We present an experimental study of the propagation of quantum noise in a multiple scattering random medium. Both static and dynamic scattering measurements are performed: the total transmission of noise is related to the mean free path for scattering, while the noise frequency correlation function determines the diffusion constant. The quantum noise observables are found to scale markedly differently with scattering parameters compared to classical noise observables. The measurements are explained with a full quantum model of multiple scattering.

description: Gaussian processes are frequently deployed as part of larger machine learning and decision-making systems, for instance in geospatial modeling, Bayesian optimization, or in latent Gaussian models. Within a system, the Gaussian process model needs to perform in a stable and reliable manner to ensure it interacts correctly with other parts of the system. In this work, we study the numerical stability of scalable sparse approximations based on inducing points. To do so, we first review numerical stability, and illustrate typical situations in which Gaussian process models can be unstable. Building on stability theory originally developed in the interpolation literature, we derive sufficient and in certain cases necessary conditions on the inducing points for the computations performed to be numerically stable. For low-dimensional tasks such as geospatial modeling, we propose an automated method for computing inducing points satisfying these conditions. This is done via a modification of the cover tree data structure, which is of independent interest. We additionally propose an alternative sparse approximation for regression with a Gaussian likelihood which trades off a small amount of performance to further improve stability. We provide illustrative examples showing the relationship between stability of calculations and predictive performance of inducing point methods on spatial tasks.

description: Using a large sample of D0 to K mu nu and pi mu nu decays collected by the FOCUS photoproduction experiment at Fermilab, we present new measurements of the q^2 dependence for the f+(q^2) form factor. These measured f+(q^2) form factors are fit to common parameterizations such as the pole dominance form and compared to recent unquenched Lattice QCD calculations. We find m_pole = 1.93+-0.05+-0.03 GeV/c^2 for D0 to K mu nu and m_pole = 1.91+0.30-0.15+-0.07 GeV/c^2 for D0 to pi mu nu and f-^{K}(0)/f+^{K}(0) = -1.7+1.5-1.4+-0.3.

Prediction of Li intercalation voltages in rechargeable battery cathode materials: effects of exchange-correlation functional, van der Waals interactions, and Hubbard $U$

description: Quantitative predictions of the Li intercalation voltage and of the electronic properties of rechargeable battery cathode materials are a substantial challenge for first-principles theory due to the possibility of (1) strong correlations associated with localized transition metal $d$ electrons and (2) significant van der Waals (vdW) interactions in layered systems, both of which are not accurately captured by standard approximations to density functional theory (DFT). Here, we perform a systematic benchmark of electronic structure methods based on the widely-used generalized gradient approximation of Perdew, Burke, and Ernzerhof (PBE) and the new strongly constrained and appropriately normed (SCAN) meta-generalized gradient approximation for battery cathode materials. Studying layered Li$_x$TiS$_2$, Li$_x$NiO$_2$, and Li$_x$CoO$_2$, olivine Li$_x$FePO$_4$, and spinel Li$_x$Mn$_2$O$_4$, we compute the voltage, crystal structure, and electronic structure with and without extensions to incorporate on-site Hubbard interactions and vdW interactions. Within pure DFT (i.e., without corrections for on-site Hubbard interactions), SCAN is a significant improvement over PBE for describing cathode materials, decreasing the mean absolute voltage error by more than 50%. Although explicit vdW interactions are not critical and in cases even detrimental when applied in conjunction with SCAN, Hubbard $U$ corrections are still in general necessary to achieve reasonable agreement with experiment. We show that no single method considered here can accurately describe the voltage and overall structural, electronic, and magnetic properties (i.e., errors no more than 5% for voltage, volume, band gap, and magnetic moments) of battery cathode materials, motivating a strong need for improved electronic structure approaches for such systems.
Refugee protection for people with mental disabilities under international law
Creators: name: Tsiakos, George
Publisher: name: University of British Columbia
Year: 2010

description: The major international instrument providing asylum to refugees is the 1951 Convention relating to the Status of Refugees and its 1967 Protocol relating to the Status of Refugees (collectively, the Refugee Convention). The Refugee Convention provides international protection to individuals fleeing persecution in their countries of origin. This thesis argues that the continuing cruel, degrading, discriminating, and inhumane treatment of people with mental disabilities in some countries of the world constitutes persecution under the Refugee Convention. Furthermore, this thesis argues that the language of the Refugee Convention and recent developments in case law relating to the scope of the "particular social group" category support the right of individuals with mental disabilities to seek international protection if they fear being persecuted on account of their particular mental disability. As a result, individuals who fear such treatment for reasons of their mental disability should be entitled to refugee protection.

description: We present an online algorithm for time-varying semidefinite programs (TV-SDPs), based on the tracking of the solution trajectory of a low-rank matrix factorization, also known as the Burer-Monteiro factorization, in a path-following procedure. There, a predictor-corrector algorithm solves a sequence of linearized systems. This requires the introduction of a horizontal space constraint to ensure the local injectivity of the low-rank factorization. The method produces a sequence of approximate solutions for the original TV-SDP problem, for which we show that they stay close to the optimal solution path if properly initialized. Numerical experiments for a time-varying max-cut SDP relaxation demonstrate the computational advantages of the proposed method for tracking TV-SDPs in terms of runtime compared to off-the-shelf interior point methods.
