From cell to muscle: development of new ways to study inherited cardiomyopathies based on engineered heart tissue
Creators: name: Owen, Thomas
Publisher: name: Imperial College London
Year: 2017

description: The ACTC E99K mutation is associated with hypertrophic cardiomyopathy (HCM- predominantly apical) and left ventricular non-compaction in a large group of patients from Northwest Spain. The aim of this thesis is to set up a new way of characterising patient phenotypes combining the technologies of engineered heart tissue and iPSCs. Punch biopsies were taken from 18 individuals (14 mutation carriers and 4 related non-carriers), fibroblasts were expanded, and 6 samples (2 mutation carriers and one healthy relative each from two different families) were taken forward for Sendai virus reprogramming. Five fibroblast lines were successfully reprogrammed, which was confirmed by staining for pluripotency markers. To make isogenic pairs of cells CRISPR-Cas9 PiggyBac gene editing was used to correct the E99K mutation in two disease carrying lines, and the mutation was knocked into one wild type line. We also analysed sudden cardiac death in the ACTC1 E99K mouse model. Higher rates of SCD were seen in enriched CBA/Ca mice, but SCD was almost absent in pure black6 mice. Using two photon microscopy, pico-sirius red staining, and gene expression we showed up regulation of fibrosis in young SCD mice. In addition, pure black6 mice were also found to have the same number of calcium release events as wild type. Pluripotency was confirmed after targeting of iPSCs, and differentiation into cardiomyocytes was achieved in all six lines: Donor I E99K, Donor I WT, Donor II E99K, Donor II WT, Donor III WT, Donor III E99K. The presence of the mutation in iPSC-CM was confirmed with an antibody specific to the ACTC E99K mutation. Donor I WT line had significantly fewer cardiomyocytes which affected the subsequent experiments. Under stimulation Donor II E99K and Donor III E99K had significantly longer relaxation times than wild type isogenic pairs. Isogenic pairs were treated with increasing concentrations of calcium Donor II E99K and Donor I E99K 3 were hypercontractile compared to Donor III WT, however, this hypercontractilty was not restored in the Donor II line when the mutation was corrected to wild type. Moreover, hypercontractility was not induced in the Donor III line with the E99K mutation knocked in compared to its wild type isogenic line. Lastly, under stimulation we also found a higher rate of abnormal arrhythmogenic like contractions in Donor II E99K and Donor III E99K compared to their wild type isogenic pairs. iPSC-CM with the E99K mutation are a useful model to understand HCM and have been shown to recapitulate some aspects of the human disease. Data suggest that poor relaxation and arrhythmic events are directly related to the mutation, while hypercontractility may be related to a co-inherited genotype or epigenetic change.

description: We investigate the thermal and dynamical evolution of primordial gas clouds in the universe after decoupling. Comparing the time-scale of dynamical evolution with that of fragmentation, we can estimate the typical fragmentation scale. We propose the following scenario of the formation process of first luminous objects consisting of large number stars. First, by pancake collapse of the overdensity regions in the expanding universe or collision between clouds in potential wells, quasi-plane shocks form. If the shock-heated temperature is higher than about $10^4$ K, the postshock gas cools down to several hundred K by \Hbun line cooling, and the shock-compressed layer fragments into filamentary clouds. The filamentary cloud collapses dynamically once more and fragments into cloud cores. Finally, a primordial star forms in a cloud core. We show that the minimum mass of the first star is essentially determined by the Chandrasekhar mass. Also, we investigate the dynamical collapse of cloud cores by numerical simulation and show that the evolution paths of the central regions of the cores depend only very weakly on the total core mass. After mass accretion, a massive star may be formed in a core, since the estimated mass accretion rate is very large. In such a case, it may be possible for many massive stars form almost simultaneously. Then the clouds can be luminous objects. On the other hand, if the shock-heated temperature is lower, effective star formation is delayed significantly.

Geometrogenesis in GFT: An Analysis

description: In this paper I introduce the idea of geometrogenesis as suggested in the group field theory literature and I offer a criticism of it. Geometrogenesis in the context of GFT is the idea that what we observe as the big bang is nothing else but a phase transition from a non-geometric phase of the universe to a geometric one which is the one we live in and the one to which the spacetime concepts apply. GFT offers the machinery to speak about geometric and non-geometric phases, but I argue that there are serious conceptual issues that threaten the viability of the idea. Some of these issues are directly related to the foundations of GFT and are concerned with the fact that it isn't clear what GFT amounts to and how to understand it. The other main source of trouble has to do with geometrogenesis itself and its conceptual underpinnings as it is unclear whether it requires the addition of an extra temporal or quasitemporal dimension which is unwanted and problematic.

Moir{é} pattern assisted geometric resonant tunneling in disordered twisted bilayer graphene

description: We investigate the mesoscopic transport through a twisted bilayer graphene (TBG) consisting of a clean graphene nanoribbon on the bottom and a disordered graphene disc on the top. We show that, with strong top-layer disorder the transmission through such a device shows a sequence of resonant peaks with respect to the rotation angle $θ$, where at the resonance angles $θ_c$ the disc region contains one giant hexagonal moir{é} supercell. A further investigation shows that the value of $θ_c$ shows negligible dependence on the disorder strength, the Fermi energy, and the shape distortion, indicating the resonance is a robust geometric feature of the moir{é} supercell. We explain this geometric resonance based on the bound states formed inside the moir{é} supercell, with their averaged local density of states dominating at the AA stacking region while minimizing at the AB stacking region. By increasing the interlayer distance, the peak becomes less pronounced which further confirms the role of interlayer coupling. The results presented here suggest a new mechanism to tune the quantum transport signal through the twist angle in disordered moir{é} systems.
The effect of model and human synovial fluid chemistry on wear of CoCrMo in bench tests
Creators: name: Stevenson, Harriet
Publisher: name: Imperial College London
Year: 2018

description: Prostheses, for example hips and knees, are used to relieve pain and restore function in degenerated synovial joints. They are tribological devices and are susceptible to wear of the bearing surface which can lead to early failure. Human synovial fluid (HSF) is produced to lubricate the joint, however in tribological testing of implants 25%w/w Bovine Calf Serum (25BCS) is used as a screening fluid, although the composition is different. The key questions addressed in this thesis are: the lubrication and wear mechanisms similar? Is 25BCS an appropriate replacement for HSF in wear tests? A ball-on disc CoCrMo wear test was developed to use small lubricant volumes suitable for HSF, which was supplied by the Musculoskeletal Group at Imperial College. Post-test the wear was measured, and surface deposits analysed to provide insights into lubrication mechanisms. Friction and wear of HSF samples were compared to BCS and model fluids comprising of proteins (albumin and globulin), lipids and hyaluronic acid. The wear depth for most HSF samples was significantly higher (up to 77%) compared to 25BCS. Deposited films were observed in and around the wear scar and the pattern was similar for all protein containing fluids including HSF. The deposits appeared to be viscous, insoluble and adherent to the surface. Micro-IRRAS analysis showed they were formed of denatured proteins although in some instance lipids were present. Analysis of the amide I band showed the protein secondary structure was transformed to an increased native β-sheet content with some fibular β-sheet structures. Thioflavin T (ThT) was used to confirm the presence of β-sheet amyloid fibrils. The research showed that 25BCS isn’t an appropriate substitute for HSF. The lubrication and wear mechanisms are similar, however 25BCS has a greater tendency to form high β-sheet content deposits due to their chemical composition that protect surfaces from wearing.

description: We present the power spectrum analysis of clustering in the Durham/UKST Galaxy Redshift Survey, which covers 1450 square degrees and consists of 2501 galaxy redshifts sampled at a rate of 1 in 3 to b_J = 17. The fluctuations that we measure can be expressed as sigma_{8} = 1.01 +/- 0.17 . We find remarkably good agreement between the power spectrum measured for the Durham/UKST Survey and those from other optical studies, in spite of the very different sampling rates, magnitude limits and survey geometries employed, on scales up to lambda = (2 pi)/k = 80/h Mpc. On scales larger than this we find good agreement with the power measured from the Stromlo-APM Survey (Tadros & Efstathiou), but find more power than estimated from the Las Campanas Redshift Survey (Lin et al). We apply a simple model for redshift space distortions to the real space APM Galaxy Survey power spectrum and find a shape and amplitude that is in very good agreement with the power spectrum of the Durham/UKST Survey. This implies beta=Omega^{0.6}/b=0.60 +/- 0.35, where Omega is the density parameter and b is the bias between fluctuations in the galaxy and mass distributions, and also suggests a one dimensional velocity dispersion of sigma = 320 +/-140 km/s. We find that for any choice of normalisation, the standard CDM model has a shape that cannot be reconciled with the Durham/UKST Survey power spectrum, unless either unacceptably high values of the one dimensional velocity dispersion are adopted or the assumption that bias is constant is invalid on scales greater than 20/h Mpc. Over the range of wavenumbers for which we have a robust measurement of the power spectrum, we find the best agreement is obtained for a critical density CDM model in which the shape of the power spectrum is modified.

The burden of antimicrobial resistance: the case of escherichia coli
Creators: name: Naylor, Nichola Rochelle
Publisher: name: Imperial College London
Year: 2019

description: Introduction: Antimicrobial resistance is considered a potential threat to global population health. National and international surveillance reports highlight the epidemiological burden of antibiotic resistant Escherichia coli, with particular reference to urinary tract infections (UTIs) and bacteraemia. Evidence on the health and cost burden of such infections in England is unknown; such evidence is needed to evaluate policies targeting antibiotic resistance and Gram-negative infections. Aim: The aim of this thesis was to estimate the burden of antibiotic resistant and susceptible E. coli infections in England, from the patient, healthcare system and labour productivity perspectives. Methods: The population of interest included adults in England with E. coli bacteraemia and/or UTIs. Cox proportional hazards, multistate and cohort simulation models were utilised to achieve the aim of the thesis. Data sources included national surveillance data, national hospital administrative data and published evidence. Results: It was estimated that antibiotic resistant and susceptible E. coli infections reduced annual, national health in 2015 (as measured by Quality-adjusted life years (QALYs)) by 303 QALYs and 1,136 QALYs, respectively. Though it was estimated that third-generation cephalosporin resistance and piperacillin/tazobactam resistance were individually associated with excess costs-per-case of over £300, antibiotic susceptible E. coli infections cost the NHS significantly more on an annual, national basis. The total societal cost (healthcare system and labour productivity costs combined) of E. coli UTIs and bacteraemia was estimated to be over £26.5 million in 2015. Conclusion: Both antibiotic resistant and susceptible E. coli infections cause a substantial burden to the English population, healthcare system and society. Investment in ‘infection prevention and control’ measures alongside antibiotic stewardship policy is required to alleviate this burden. Future research can apply the methods utilised in this thesis to other microbes, in other settings, to establish a robust evidence base regarding the burden of antimicrobial resistant and susceptible infections.

description: The optimization algorithm and its hyperparameters can significantly affect the training speed and resulting model accuracy in machine learning applications. The wish list for an ideal optimizer includes fast and smooth convergence to low error, low computational demand, and general applicability. Our recently introduced continual resilient (CoRe) optimizer has shown superior performance compared to other state-of-the-art first-order gradient-based optimizers for training lifelong machine learning potentials. In this work we provide an extensive performance comparison of the CoRe optimizer and nine other optimization algorithms including the Adam optimizer and resilient backpropagation (RPROP) for diverse machine learning tasks. We analyze the influence of different hyperparameters and provide generally applicable values. The CoRe optimizer yields best or competitive performance in every investigated application, while only one hyperparameter needs to be changed depending on mini-batch or batch learning.

description: Depth notions in regression have been systematically proposed and examined in Zuo (2018). One of the prominent advantages of notion of depth is that it can be directly utilized to introduce median-type deepest estimating functionals (or estimators in empirical distribution case) for location or regression parameters in a multi-dimensional setting. Regression depth shares the advantage. Depth induced deepest estimating functionals are expected to inherit desirable and inherent robustness properties ( e.g. bounded maximum bias and influence function and high breakdown point) as their univariate location counterpart does. Investigating and verifying the robustness of the deepest projection estimating functional (in terms of maximum bias, asymptotic and finite sample breakdown point, and influence function) is the major goal of this article. It turns out that the deepest projection estimating functional possesses a bounded influence function and the best possible asymptotic breakdown point as well as the best finite sample breakdown point with robust choice of its univariate regression and scale component.

description: We consider the thermoelectric response of chaotic or disordered quantum dots in the limit of phase-coherent transport, statistically described by random matrix theory. We calculate the full distribution of the thermoelectric coefficients (Seebeck $S$ and Peltier $Π$), and the thermoelectric figure of merit $ZT$, for large open dots at arbitrary temperature and external magnetic field, when the number of modes in the left and right leads ($N_{\rm L}$ and $N_{\rm R}$) are large. Our results show that the thermoelectric coefficients and $ZT$ are maximal when the temperature is half the Thouless energy, and the magnetic field is negligible. They remain small, even at their maximum, but they exhibit a type of universality at all temperatures, in which they do not depend on the asymmetry between the left and right leads $(N_{\rm L}-N_{\rm R})$, even though they depend on $(N_{\rm L}+N_{\rm R})$.

Irreversibility and symmetry principles in quantum information
Creators: name: Cirstoiu, Cristina
Publisher: name: Imperial College London
Year: 2018

description: Symmetry principles have played a crucial role in the development of modern physics and underpin our most fundamental theories of nature. The present thesis is concerned with the analysis of symmetries in the context of quantum information theory. Whenever a quantum mechanical system interacts with its environment it is subjected to decoherence, a process that is typically irreversible and most generally treated abstractly using the concept of quantum operations. If there is an underlying symmetry principle, additional structures emerge. The central question we address is, What are the consequences of global or local gauge symmetry on the structure of many-body quantum processes?This leads us to a diagrammatic framework of decomposing quantum operations into terms that respond to the symmetry principle in particular ways and respect the causal structures involved. We present two core applications. First, we address the interplay between irreversibility and repeatable use of coherent resources under symmetry constraints. Second, we give an information-theoretic perspective on gauging globally symmetric dynamics to a local symmetry applicable even in the presence of irreversibility and thus it goes beyond the usual Lagrangian formulation. Finally, we analyse the departure from conservation laws under symmetric dynamics subject to decoherence.
Competing Drifting Radio Subpulses in PSR B0031-07

description: The pair of drifting subpulses of the radio pulsar PSR B0031-07 appear to be well separated from each other on the average, overlapping at less than one thirtieth of the peak energy. Strictly, the integrated profile of the pair (after removing the drift) does not show more than two subpulses; however this result is likely to be modified with the availability of more data. On the other hand, rare instances of three simultaneous subpulses in a single period have been noticed. This is consistent with the Ruderman and Sutherland model of the drifting phenomenon in which several sparks, uniformly spaced on a circle, rotate around the polar cap. The third subpulse appears to show up strongly when subpulses belonging to the primary drift bands weaken. Although this conclusion is based mainly on two reliable examples, it suggests an anti correlation of the subpulse energies. The normalised correlation coefficient between the energies of the two subpulses in a period is -0.16 +- 0.02, after accounting for a known selection effect. Simulations suggest that this result could not be an artefact. This suggests the idea of competing drifting subpulses which, if true, will have important ramifications for the growth and breakdown of the particle acceleration zones in pulsars.

description: The Kubo formula is a cornerstone in our understanding of near-equilibrium transport phenomena. While conceptually elegant, the application of Kubo's linear-response theory to interesting problems is hindered by the need for algorithms that are accurate and scalable to large lattice sizes beyond one spatial dimension. Here, we propose a general framework to numerically study large systems, which combines the spectral accuracy of Chebyshev expansions with the efficiency of divide-and-conquer methods. We use the hybrid algorithm to calculate the two-terminal conductance and the bulk conductivity tensor of 2D lattice models with over $10^7$ sites. By efficiently sampling the microscopic information contained in billions of Chebyshev moments, the algorithm is able to accurately resolve the linear-response properties of complex systems in the presence of quenched disorder. Our results lay the groundwork for future studies of transport phenomena in previously inaccessible regimes.

description: We have performed high-resolution hydrodynamic simulations of the Lyman-alpha forest in a variety of popular cold dark matter dominated cosmologies, including a low density and a vacuum-dominated model. The fluctuation amplitude of these models is chosen to match the observed abundance of galaxy clusters at low redshift. We assume that the intergalactic medium is photoionized and photoheated by a uniform UV-background with the required amplitude to give the observed mean hydrogen absorption. We produce simulated spectra, analyze them by fitting Voigt profiles and compare line statistics with those obtained from high resolution observations. All models give column density distributions in good agreement with observations. However, the distribution of line widths (the b-parameter distribution) reflects differences in the temperature of the intergalactic medium between the models, with colder models producing more narrow lines. All the models with a low baryon density, Omega_b h^2=0.0125, are too cold to produce a b-parameter distribution in agreement with observations. Models with a higher baryon density, Omega_b h^2=0.025, are hotter and provide better fits. Peculiar velocities contribute significantly to the line widths in models with low matter density, and this improves the agreement with observations further. We briefly discuss alternative mechanisms for reconciling the simulations with the observed b-parameter distributions.

description: We investigate the properties of K0V stars with Hipparcos parallaxes and spectral types taken from the Michigan Spectral Survey. The sample of 200 objects allows the empirical investigation of the magnitude selection (Malmquist) bias, which appears clearly present. By selecting those objects that are not affected by bias, we find a mean absolute magnitude of Mv~5.7, a downward revision from 5.9 mag. listed in Schmidt-Kaler (1982). Some objects have absolute magnitudes far brighter than Mv~5.7, and it is suggested that these objects (~20% of the total sample) are K0IV stars which may have been mis-classified as a K0V star. The presence of the Malmquist bias in even this high quality sample suggests that no sample can be expected to be bias-free.

description: Quantum phase transitions are usually classified into discrete universality classes that typically only depend on symmetries and spatial dimensionalities. In this Letter, we demonstrate an opportunity to continuously vary the critical exponents or universalities by tuning experimental parameters in a given physical system. Particularly, we show that critical exponents in long-range spin systems simulated in ion traps can be easily tuned with laser detuning. We suggest that such experiments also effectively simulate some aspects of critical phenomena in conventional spin systems but in artificial non-integer spatial dimensions.

description: We present the results of a systematic search for point-like and moderately extended soft (0.1-2.4 keV) X-ray sources in a raster of nine pointings covering a field of 8.95 deg^2 and performed with the ROSAT PSPC between October 1991 and October 1993 in the direction of the Small Magellanic Cloud. We detect 248 objects which we include in the first version of our SMC catalogue of soft X-ray sources. We set up seven source classes defined by selections in the count rate, hardness ratio and source extent. We find five high luminosity super-soft sources (1E 0035.4-7230, 1E 0056.8-7146, RX J0048.4-7332, RX J0058.6-7146 and RX J0103-7254), one low-luminosity super-soft source RX J0059.6-7138 correlating with the planetary nebula L357, 51 candidate hard X-ray binaries including eight bright hard X-ray binary candidates, 19 supernova remnants, 19 candidate foreground stars and 53 candidate background active galactic nuclei (and quasars). We give a likely classification for ~60% of the catalogued sources. The total count rate of the detected point-like and moderately extended sources in our catalogue is 6.9+/-0.3 s^-1, comparable to the background subtracted total rate from the integrated field of ~6.1+/-0.1 s^-1.

description: A new measure of information leakage for quantum encoding of classical data is defined. An adversary can access a single copy of the state of a quantum system that encodes some classical data and is interested in correctly guessing a general randomized or deterministic function of the data (e.g., a specific feature or attribute of the data in quantum machine learning) that is unknown to the security analyst. The resulting measure of information leakage, referred to as maximal quantum leakage, is the multiplicative increase of the probability of correctly guessing any function of the classical data upon observing measurements of the quantum state. Maximal quantum leakage is shown to satisfy post-processing inequality (i.e., applying a quantum channel reduces information leakage) and independence property (i.e., leakage is zero if the quantum state is independent of the classical data), which are fundamental properties required for privacy and security analysis. It also bounds accessible information. Effects of global and local depolarizing noise models on the maximal quantum leakage are established.

Development of new intelligent autonomous robotic assistant for hospitals
Creators: name: Vicente, Alexandre
Publisher: name: Imperial College London
Year: 2018

description: Continuous technological development in modern societies has increased the quality of life and average life-span of people. This imposes an extra burden on the current healthcare infrastructure, which also creates the opportunity for developing new, autonomous, assistive robots to help alleviate this extra workload. The research question explored the extent to which a prototypical robotic platform can be created and how it may be implemented in a hospital environment with the aim to assist the hospital staff with daily tasks, such as guiding patients and visitors, following patients to ensure safety, and making deliveries to and from rooms and workstations. In terms of major contributions, this thesis outlines five domains of the development of an actual robotic assistant prototype. Firstly, a comprehensive schematic design is presented in which mechanical, electrical, motor control and kinematics solutions have been examined in detail. Next, a new method has been proposed for assessing the intrinsic properties of different flooring-types using machine learning to classify mechanical vibrations. Thirdly, the technical challenge of enabling the robot to simultaneously map and localise itself in a dynamic environment has been addressed, whereby leg detection is introduced to ensure that, whilst mapping, the robot is able to distinguish between people and the background. The fourth contribution is geometric collision prediction into stabilised dynamic navigation methods, thus optimising the navigation ability to update real-time path planning in a dynamic environment. Lastly, the problem of detecting gaze at long distances has been addressed by means of a new eye-tracking hardware solution which combines infra-red eye tracking and depth sensing. The research serves both to provide a template for the development of comprehensive mobile assistive-robot solutions, and to address some of the inherent challenges currently present in introducing autonomous assistive robots in hospital environments.

Relaxation in stellar systems and the shape and rotation of the inner dark halo
Creators: name: Tremaine, S.
name: Ostriker, J. P.
Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Why do galactic bars rotate with high pattern speeds, when dynamical friction should rapidly couple the bar to the massive, slowly rotating dark halo? This longstanding paradox may be resolved by considering the dynamical interactions between the galactic disk and structures in the dark halo. Dynamical friction between small-scale halo structure and the disk spins up and flattens the inner halo, thereby quenching the dynamical friction exerted by the halo on the bar; at the same time the halo heats and thickens the disk, perhaps forming a rapidly rotating bulge. Two possible candidates for the required halo structures are massive black holes and tidal streamers from disrupted precursor halos. More generally, gravitational scattering from phase-wrapped inhomogeneities represents a novel relaxation process in stellar systems, intermediate between violent relaxation and two-body relaxation, which can isotropize the distribution function at radii where two-body relaxation is not effective.

The geometry of phase mixing
Creators: name: Tremaine, S.
Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Partially phase-mixed structures in galaxies occupy a complex surface of dimension D in six-dimensional phase space. The appearance of such structures to observers is determined by their projection into a subspace whose dimensionality K is determined by the number of observables (e.g. sky position, distance, radial velocity, etc.). We discuss the expected dimensionality of phase-space structures and suggest that the most prominent features in surveys with K=D or K>D will be stable singularities (catastrophes). The simplest of these are the shells seen in the outer parts of elliptical galaxies.

The dynamics of continuous-time recurrent neural networks and their relevance to episodic memory
Creators: name: Nikiforou, Kyriacos
Publisher: name: Imperial College London
Year: 2019

description: Continuous-time recurrent neural networks (CTRNNs) are both plausible models of cortical circuits and practically relevant for biologically inspired machine learning. To date, their dynamics are not well understood, especially when they are driven by external signals, and are hence typically treated as a “black box”. This work builds on previous attempts to better understand the complex dynamics of CTRNNs. A series of computational experiments are presented whose aim is to reveal, through both visualisation and analysis, the dynamical transitions exhibited by these networks when driven by external periodic signals. On the applications front, the suitability of CTRNNs for episodic-like memory is explored, using the reservoir computing paradigm. This paradigm has emerged as a simple approach to overcoming important limitations of the gradient-based methods conventionally used to train recurrent neural networks. To explore their applicability to episodic-like memory, CTRNNs are trained to memorise and reconstruct sequences of high-dimensional images, representing episodic experiences. The various parameters affecting network performance are investigated, revealing a strong dependence on the dynamic regime the networks operate in. Finally, a simple computational experiment is presented using CTRNNs with modular, small-world connectivity. The aim is to visualise information broadcast in complex networks, as well as to provide computational support for the plausibility of the “connective core hypothesis”, which posits a particular relationship between connectivity and information flow in the brain. The experiments and findings presented in this work offer a deeper and more intuitive understanding of the dynamics of continuous-time recurrent neural networks, and open up new avenues for future research in both their theory and application.

description: Let $\mathbf{A}$ be a finite nilpotent algebra in a congruence modular variety with finitely many fundamental operations. If $\mathbf{A}$ is of prime power order, then it is known that there is a polynomial $p$ such that for every $n \in \mathbb{N}$, every $n$-generated algebra in the variety generated by $\mathbf{A}$ has at most $2^{p(n)}$ elements. We present a bound on the degree of this polynomial.
