Structural, Electrical and Magnetic Properties of CoFe2O4 and BaTiO3 Layered Nanostructures on Conductive Metal Oxides
Creators: name: Aguesse, Frederic
Publisher: name: Imperial College London
Year: 2011

description: Multiferroic materials exhibit simultaneously, magnetic and electric order. In a magnetoelectric composite structure, a coupling is induced via an interfacial elastic interaction between magnetostrictive and piezoelectric materials enabling the control of the magnetisation by applying an electric field and vice versa. However, despite the potential of such coupling, experimental limits of theoretical models were observed. This work sheds some light on these limits by focusing the research on the chemistry of nanocomposite CoFe2O4 and BaTiO3, particularly at the interfaces where the coupling predominates. A comparison of the most common conductive oxides, Nb doped SrTiO3 and SrRuO3, was made for the bottom electrode application. The variation of conductive properties in Nb-SrTiO3 thin films at high temperature has been quantified when artificially strained and 60 nm SrRuO3 film was found to be the best bottom electrode choice for room temperature use. Epitaxial growth of magnetic CoFe2O4 was achieved on various metal oxide substrates despite large lattice mismatches. Crystallographic properties and strain evaluation were investigated and a Stranski-Krastanov growth mechanism, arising from the PLD deposition, was predominant. A notable drop of magnetisation was observed depending on the growth template, particularly on BaTiO3 substrates, the piezoelectric counterpart of the magnetoelectric structures. However, an encouraging magnetoelectric coupling induced by thermal phase transition of BaTiO3 was revealed. For BaTiO3, a control of the growth direction was realised by varying the deposition pressure, and the existence of both 180° and 90° ferroelectric domains was observed for films up to 300 nm in thickness. However, both the ferroelectric and piezoelectric properties were reduced in the thin films due to the clamping effect of the substrate. Finally, highly crystalline multilayers of CoFe2O4 and BaTiO3 were prepared on SrRuO3 buffered SrTiO3 substrates. It was found that the degradation of both magnetic and ferroelectric properties was proportional to the increase in the number of interfaces. A thorough microscopic study revealed interdiffusion and chemical instability occurring between CoFe2O4 and BaTiO3 at the interface. This undesired effect was partially recovered by the insertion of an ultra thin layer of SrTiO3, acting as a barrier layer at every interface. This research shows how interfacial chemistry need to be understood to achieve high magnetoelectric coupling in these types of epitaxial engineered structures.
Hierarchical Coded Computation
Creators: name: Ferdinand, Nuwan

Publisher: name: arXiv
Year: 2018
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: Coded computation is a method to mitigate "stragglers" in distributed computing systems through the use of error correction coding that has lately received significant attention. First used in vector-matrix multiplication, the range of application was later extended to include matrix-matrix multiplication, heterogeneous networks, convolution, and approximate computing. A drawback to previous results is they completely ignore work completed by stragglers. While stragglers are slower compute nodes, in many settings the amount of work completed by stragglers can be non-negligible. Thus, in this work, we propose a hierarchical coded computation method that exploits the work completed by all compute nodes. We partition each node's computation into layers of sub-computations such that each layer can be treated as (distinct) erasure channel. We then design different erasure codes for each layer so that all layers have the same failure exponent. We propose design guidelines to optimize parameters of such codes. Numerical results show the proposed scheme has an improvement of a factor of 1.5 in the expected finishing time compared to previous work.

description: Invasive electroencephalograph (EEG) recordings of ten patients suffering from focal epilepsy were analyzed using the method of renormalized entropy. Introduced as a complexity measure for the different regimes of a dynamical system, the feature was tested here for its spatio-temporal behavior in epileptic seizures. In all patients a decrease of renormalized entropy within the ictal phase of seizure was found. Furthermore, the strength of this decrease is monotonically related to the distance of the recording location to the focus. The results suggest that the method of renormalized entropy is a useful procedure for clinical applications like seizure detection and localization of epileptic foci.

Mathematical Modelling and FTIR Spectroscopic Imaging of Pharmaceutical Tablet Dissolution
Creators: name: Kimber, James A.
Publisher: name: Imperial College London
Year: 2012

description: The process of pharmaceutical tablet dissolution is a vital stage in the delivery of active pharmaceutical ingredients (APIs). The constituent components and their spatial arrangement within the tablet determine the release characteristics of the API. It is therefore important to understand and characterise the various processes and component interactions that occur during tablet dissolution. Computational simulations of tablet dissolution can be used to obtain parametric sensitivities and optimise formulations so that the desired API release profile is achieved. This thesis describes the methods behind modelling the behaviour of non-swelling and swelling tablets, the mathematical validation of the models, parametric studies and the experiments which were used to obtain parameters and verify the models. The experimental method used in this work is Fourier Transform Infrared (FTIR) spectroscopic imaging, which, when using an attenuated total reflection (ATR) accessory and flow cell, enable chemical and spatial information to be obtained from the tablet as it dissolves. UV/Visible spectroscopy was also used to obtain drug release information. The non-swelling model discretised a tablet over a Cartesian grid and solved the mass transfer equations (dissolution and diffusion) to obtain drug release profiles. Two parametric studies were conducted where the particle size distribution and mass fractions were varied in one, and the API diffusivity, saturated concentration and mass fraction in the other to see what effect these had on drug release, demonstrating the importance of the choice of excipient and the impact of particle size on release variability. For experimental validation, tablets containing different quantities of polyethylene glycol and nicotinamide were dissolved and imaged, and optimisation was used to obtain the pure component saturated concentrations. The model was then tested against a different tablet to demonstrate the predictive capability of the model. The swelling model discretised a tablet into small cylindrical particles, whose size was proportional to the mass of components within them and whose motion was determined using the Discrete Element Method (DEM). As water diffused into polymer particles, they could expand, resulting in macroscopic swelling. The DEM model of a swelling and dissolving tablet was validated against a numerically exact model of the same tablet and parametric studies were conducted into the effect of polymer disentanglement threshold, polymer equilibrium water fraction and polymer dissolution rate. The model was also optimised against a dissolving tablet containing HPMC to obtain parameters for this excipient. To conclude, both models were implemented, validated and found to accurately describe the dissolution kinetics of both swelling and non-swelling tablets.

description: It is shown that in the two-exponential version of Liouville theory the coefficients of the three-point functions of vertex operators can be determined uniquely using the translational invariance of the path integral measure and the self-consistency of the two-point functions. The result agrees with that obtained using conformal bootstrap methods. Reflection symmetry and a previously conjectured relationship between the dimensional parameters of the theory and the overall scale are derived.

Realistic estimates of superconducting properties for the cuprates: reciprocal-space diagrammatic expansion combined with variational approach

Publisher: name: arXiv

description: We propose a systematic approach to the systems of correlated electrons, the so-called $\mathbf{k}$-DE-GWF method, based on reciprocal-space ($\mathbf{k}$-resolved) diagrammatic expansion of the variational Gutzwiller-type wave function for parametrized models of correlated fermions. The present approach, in contrast to either variational Monte-Carlo (VMC), or the recently developed real-space diagrammatic expansion of the Gutzwiller-type wave function (direct-space DE-GWF technique), is applicable directly in the thermodynamic limit and thus is suitable for describing selected singular features of the wave-vector-dependent quantities. We employ the $\mathbf{k}$-DE-GWF method to extract the non-analytic part of the two leading moments of the fermion spectral-density function across the (two-dimensional) Brillouin zone for the Hubbard model and away from the half-filling. Those moments are used to evaluate the nodal quasiparticle velocities and their spectral weights in the correlated superconducting state. The two velocities determined in that manner exhibit scaling with the electron concentration qualitatively different from that obtained earlier for the excited states of the high-$T_c$ cuprates within the projected quasi-particle ansatz, and the results are in a very good quantitative agreement with experimental data if interpreted as those characterizing the spectrum below and above the observed kink. We provide a detailed discussion of the two gaps and two excitation branches (two velocities) appearing naturally within our DE-GWF approach. The two separate sets of characteristics distinguish the renormalized quasiparticle states very close to the Fermi surface from the deeper correlated-state properties. Also, an enhancement of the $\mathbf{k}$-dependent magnetic susceptibility is shown to contain a spin-fluctuation contribution within our language.

String-Inspired Gravity with Interacting Point Particles

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We reformulate two dimensional string-inspired gravity with point particles as a gauge theory of the extended Poincaré group. A non-minimal gauge coupling is necessary for the equivalence of the two descriptions. The classical one-particle problem is analyzed completely. In addition, we obtain the many-particle effective action after eliminating the gravity degrees of freedom. We investigate properties of this effective action, and show how to recover the geometrical description. Quantization of the gauge-theoretic model is carried out and the explicit one-particle solution is found. However, we show that the formulation leads to a quantum mechanical inconsistency in the two-particle case. Possible cures are discussed.

Optimal finite-differences discretization for the diffusion equation from the perspective of large-deviation theory

description: When applying the finite-differences method to numerically solve the one-dimensional diffusion equation, one must choose discretization steps $Δx$, $Δt$ in space and time, respectively. By applying large-deviation theory on the discretized dynamics, we analyze the numerical errors due to the discretization, and find that the (relative) errors are especially large in regions of space where the concentration of particles is very small. We find that the choice $Δt = {Δx}^2 / (6D)$, where $D$ is the diffusion coefficient, gives optimal accuracy compared to any other choice (including, in particular, the limit $Δt \to 0$), thus reproducing the known result that may be obtained using truncation error analysis. In addition, we give quantitative estimates for the dynamical lengthscale that describes the size of the spatial region in which the numerical solution is accurate, and study its dependence on the discretization parameters. We then turn to study the advection-diffusion equation, and obtain explicit expressions for the optimal $Δt$ and other parameters of the finite-differences scheme, in terms of $Δx$, $D$ and the advection velocity. We apply these results to study large deviations of the area swept by a diffusing particle in one dimension, trapped by an external potential $\sim |x|$. We extend our analysis to higher dimensions by combining our results from the one dimensional case with the locally one-dimension method.

Continuous and Segmented-Flow Microfluidics for Biomolecular Analysis
Creators: name: Pereira, Fiona Marie
Publisher: name: Imperial College London
Year: 2011

description: Segmented flows in microfluidics have attracted much recent attention. Of particular interest is the use of nanolitre droplets as interface tools in microfluidics. A droplet interface connects techniques while leaving them sufficiently independent of each other; a task that difficult to perform within a continuous flow system. The first part of this thesis is dedicated to sample preparation and analysis in continuous flow microfluidic systems. The polymerase chain reaction (PCR) is investigated, using electroosmotic flow to transport the sample across various temperature zones. Additionally, a novel sieving matrix for electrophoretic separation of dsDNA fragments and PCR amplicons on microchip and capillary is demonstrated. The second part of this thesis focuses on interfacing segmented and continuous flows. Two novel interfaces are described and demonstrated. The first interface connects droplet flows and a chip-based electrophoresis device. Using this interface, samples or reactions performed in droplets can be directly transferred to a separation channel without suspending the separation. This allows multiple samples to be analysed in a single separation channel, without cross contamination between droplets. Consequently, PCR reactions and dsDNA calibration ladders can be prepared in droplet format and analysed in high throughput. The second interface links nano-liquid chromatography and MALDI mass spectrometry. Droplet fractionation post nano-LC separation is used to preserve resolution between separated bands. The droplets are subsequently delivered to a MALDI plate for mass spectrometric analysis by removing the continuous oil phase using a hydrophobic oleophilic membrane. The tools developed here reduce manual intervention and provide a link between multiple analytical techniques involved in biomolecule analysis. These innovations will improve reproducibility and reduce cross-contamination between samples.

Earnings Quality and Bank Equity
Creators: name: Lawal, Tolulola Olusegun
Publisher: name: Imperial College London
Year: 2012

description: This doctoral thesis reports the results of three studies that address the implications of two bank characteristics - bank efficiency and bank earnings quality - for bank dividend policy and specified capital market outcomes. Chapter 1 introduces the thesis. The first study links the market reactions to dividend change announcements by banks to changes in bank efficiency score, our new measure of bank overinvestment problem, derived from a frontier analysis of bank input-output combinations. We find that improvement in bank overinvestment problem, defined as changes in bank efficiency, is significantly and positively associated with market reactions following dividend increases. However, consistent with the moderating role of bank regulation, we find no support for the role of changes in bank efficiency in market reactions to dividend decreases. The second study establishes a link between bank earnings quality and bank cost of equity capital. Using various earnings quality measures, the study finds that banks with better earnings quality experience lower cost of equity capital. Consistent with this primary finding, our results also support the idea that banks with higher earnings quality enjoy higher market valuation and higher price-earnings multiples compared to banks with lower earnings quality. Overall, our results suggest that markets can differentiate between “good” and “bad” earnings and seem to compensate banks with better earnings quality. The third study contributes to the literature by first developing a country-specific index of bank earnings quality. We further hypothesise that banks in countries characterised by high earnings quality pay more dividends than banks in countries with lower earnings quality. Our data give support to this hypothesis. Finally, using modified partial adjustment models that incorporate our index of earnings quality, we find that the dividend-earnings relation is stronger for banks operating in countries with high earnings quality than for banks operating in countries with low earnings quality.

A Framework for Learning by Demonstration in Multi-teacher Multi-robot Scenarios
Creators: name: Fernandes Martins, Murilo
Publisher: name: Imperial College London
Year: 2012

description: As robots become more accessible to humans, more intuitive and human-friendly ways of programming them with interactive and group-aware behaviours are needed. This thesis addresses the gap between Learning by Demonstration and Multi-robot systems. In particular, this thesis tackles the fundamental problem of learning multi-robot cooperative behaviour from concurrent multi-teacher demonstrations, problem which had not been addressed prior to this work. The core contribution of this thesis is the design and implementation of a novel, multi- layered framework for multi-robot learning from simultaneous demonstrations, capable of deriving control policies at two different levels of abstraction. The lower level learns models of joint-actions at trajectory level, adapting such models to new scenarios via feature mapping. The higher level extracts the structure of cooperative tasks at symbolic level, generating a sequence of robot actions composing multi-robot plans. To the best of the author's knowledge, the proposed framework is the first Learning by Demonstration system to enable multiple human demonstrators to simultaneously teach group behaviour to multiple robots learners. A series of experimental tests were conducted using real robots in a real human workspace environment. The results obtained from a comprehensive comparison confirm the appli- cability of the joint-action model adaptation method utilised. What is more, the results of several trials provide evidence that the proposed framework effectively extracts rea- sonable multi-robot plans from demonstrations. In addition, a case study of the impact of human communication when using the proposed framework was conducted, suggesting no evidence that communication affects the time to completion of a task, but may have a positive effect on the extraction multi-robot plans. Furthermore, a multifaceted user study was conducted to analyse the aspects of user workload and focus of attention, as well as to evaluate the usability of the teleoperation system, highlighting which parts were necessary to be improved.

description: Ion trap systems built upon microfabricated chips have emerged as a promising platform for quantum computing to achieve reproducible and scalable structures. However, photo-induced charging of materials in such chips can generate undesired stray electric fields that disrupt the quantum state of the ion, limiting high-fidelity quantum control essential for practical quantum computing. While crude understanding of the phenomena has been gained heuristically over the past years, explanations for the microscopic mechanism of photo-generated charge carrier dynamics remains largely elusive. Here, we present a photo-induced charging model for semiconductors, whose verification is enabled by a systematic interaction between trapped ions and photo-induced stray fields from exposed silicon surfaces in our chip. We use motion-sensitive qubit transitions to directly characterize the stray field and analyze its effect on the quantum dynamics of the trapped ion. In contrast to incoherent errors arising from the thermal motion of the ion, coherent errors are induced by the stray field, whose effect is significantly imprinted during the quantum control of the ion. These errors are investigated in depth and methods to mitigate them are discussed. Finally, we extend the implications of our study to other photo-induced charging mechanisms prevalent in ion traps.

description: Entropy production and dynamical activity are two complementary aspects in nonequilibrium physics. The asymmetry of cross-correlation, serving as a distinctive feature of nonequilibrium, also finds widespread utility. In this Letter, we establish two thermodynamic bounds on the normalized asymmetry of cross-correlation in terms of dynamical activity and entropy production rate. These bounds demonstrate broad applicability, and offer experimental testability.

Probing anomalous $Wtb$ couplings at the LHC in single top quark production through $t$-channel

description: We study the sensitivity of certain observables to the anomalous right tensorial coupling in single top production at the LHC at $\sqrt{s}=13 \text{ TeV}$. The observables consist of asymmetries constructed from the energy and angles of the decay products of the top quark produced in single top production through $t$-channel. The computation is done at Leading Order (LO) and Next-to-Leading Order (NLO) in the strong coupling in the $5$ flavor scheme. We have estimated projected limits on the anomalous coupling, both at the parton level without cuts and at the particle level with cuts. We find that the asymmetries are robust with respect to the higher order QCD corrections and are indeed a very good probe of this anomalous coupling of the top. Hence they can be used as experimental probes of the same.

Galilean Invariant Preconditioned Central Moment Lattice Boltzmann Method without Cubic Velocity Errors for Efficient Steady Flow Simulations

description: Lattice Boltzmann (LB) models used for the computation of fluid flows represented by the Navier-Stokes (NS) equations on standard lattices can lead to non-Galilean invariant (GI) viscous stress involving cubic velocity errors. This arises from the dependence of their third order diagonal moments on the first order moments for standard lattices, and strategies have recently been introduced to restore GI without such errors using a modified collision operator involving either corrections to the relaxation times or to the moment equilibria. Convergence acceleration in the simulation of steady flows can be achieved by solving the preconditioned NS equations, which contain a preconditioning parameter that alleviates the numerical stiffness. In the present study, we present a GI formulation of the preconditioned cascaded central moment LB method used to solve the preconditioned NS equations, which is free of cubic velocity errors on a standard lattice. A Chapman-Enskog analysis reveals the structure of the spurious non-GI defect terms and it is demonstrated that the anisotropy of the resulting viscous stress is dependent on the preconditioning parameter, in addition to the fluid velocity. It is shown that partial correction to eliminate the cubic velocity defects is achieved by scaling the cubic velocity terms in the off-diagonal third-order moment equilibria with the square of the preconditioning parameter. Furthermore, we develop additional corrections based on the extended moment equilibria involving gradient terms with coefficients dependent locally on the fluid velocity and the preconditioning parameter. Several conclusions are drawn from the analysis of the structure of the non-GI errors and the associated corrections, with particular emphasis on their dependence on the preconditioning parameter. Improvements in accuracy and convergence acceleration are demonstrated.

description: We consider the Maldacena conjecture applied to the near horizon geometry of a D1-brane in the supergravity approximation and present numerical results of a test of the conjecture against the boundary field theory calculation using DLCQ. We previously calculated the two-point function of the stress-energy tensor on the supergravity side; the methods of Gubser, Klebanov, Polyakov, and Witten were used. On the field theory side, we derived an explicit expression for the two-point function in terms of data that may be extracted from the supersymmetric discrete light cone quantization (SDLCQ) calculation at a given harmonic resolution. This yielded a well defined numerical algorithm for computing the two-point function. For the supersymmetric Yang-Mills theory with 16 supercharges that arises in the Maldacena conjecture, the algorithm is perfectly well defined; however, the size of the numerical computation prevented us from obtaining a numerical check of the conjecture. We now present numerical results with approximately 1000 times as many states as we previously considered. These results support the Maldacena conjecture and are within $10-15%$ of the predicted numerical results in some regions. Our results are still not sufficient to demonstrate convergence, and, therefore, cannot be considered to a numerical proof of the conjecture. We present a method for using a ``flavor'' symmetry to greatly reduce the size of the basis and discuss a numerical method that we use which is particularly well suited for this type of matrix element calculation.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We numerically examine the self-dual solutions of self-intersecting strings immersed in four dimensions. We find that open torus knots have topologies that can support monopole/anti-monopole as well as q-qbar production and annihilation. We give an estimate of the string tension from quark production rates, show that the intersection number for torus-knots is 4(p-q), and discuss a chiral symmetry breaking mechanism due to self-intersections. We supply a MAPLE program that can annimate the torus-knot solutions. These annimations can be found at http://www-hep.physics.uiowa.edu/~bacus/research.html under the ``Animation Control Panel''.

description: IRIS performs solar observations over a large range of atmospheric heights, including the chromosphere where the majority of flare energy is dissipated. The strong Mg II h&k spectral lines are capable of providing excellent atmospheric diagnostics, but have not been fully utilized for flaring atmospheres. We aim to investigate whether the physics of the chromosphere is identical for all flare observations by analyzing if there are certain spectra that occur in all flares. To achieve this, we automatically analyze hundreds of thousands of Mg II h&k line profiles from a set of 33 flares, and use a machine learning technique which we call supervised hierarchical k-means, to cluster all profile shapes. We identify a single peaked Mg II profile, in contrast to the double-peaked quiet Sun profiles, appearing in every flare. Additionally, we find extremely broad profiles with characteristic blue shifted central reversals appearing at the front of fast-moving flare ribbons. These profiles occur during the impulsive phase of the flare, and we present results of their temporal and spatial correlation with non-thermal hard X-ray signatures, suggesting that flare-accelerated electrons play an important role in the formation of these profiles. The ratio of the integrated Mg II h&k lines can also serve as an opacity diagnostic, and we find higher opacities during each flare maximum. Our study shows that machine learning is a powerful tool for large scale statistical solar analyses.

Exploitation of Stragglers in Coded Computation

description: In cloud computing systems slow processing nodes, often referred to as "stragglers", can significantly extend the computation time. Recent results have shown that error correction coding can be used to reduce the effect of stragglers. In this work we introduce a scheme that, in addition to using error correction to distribute mixed jobs across nodes, is also able to exploit the work completed by all nodes, including stragglers. We first consider vector-matrix multiplication and apply maximum distance separable (MDS) codes to small blocks of sub-matrices. The worker nodes process blocks sequentially, working block-by-block, transmitting partial per-block results to the master as they are completed. Sub-blocking allows a more continuous completion process, which thereby allows us to exploit the work of a much broader spectrum of processors and reduces computation time. We then apply this technique to matrix-matrix multiplication using product code. In this case, we show that the order of computing sub-tasks is a new degree of design freedom that can be exploited to reduce computation time further. We propose a novel approach to analyze the finishing time, which is different from typical order statistics. Simulation results show that the expected computation time decreases by a factor of at least two in compared to previous methods.
Water stress, root herbivory and above-ground multitrophic interactions in a crucifer-aphid system

description: Plants, insect herbivores and their natural enemies interact in multitrophic food webs that can be influenced by various stress factors. The aim of the present study was to understand the effects of two different below-ground stress factors (drought and root herbivory) on the performance of two above-ground herbivores, a generalist (Myzus persicae) and a specialist (Brevicoryne brassicae) aphid species and two of their natural enemies, a generalist (Aphidius colemani) and a specialist (Diaeretiella rapae) parasitoid species. Preliminary experiments with various Brussels sprout (Brassica oleracea) cultivars (cv) showed that aphid performance was influenced both by host plant on which the parent aphid had been reared and by the host plant on which it was feeding when reproducing. The Brussels sprout cv. Oliver was selected as a consistently good aphid host for subsequent experiments. Root herbivory and drought stress were shown to significantly affect the outcome of plant-mediated interactions between insect herbivores and their parasitoids. High drought stress had a negative impact on the aphid species and their parasitoids and also reduced performance of a root herbivore, the cabbage root fly, Delia radicum. Root herbivory alone or in combination with drought significantly altered foliar herbivore performance. High drought stress combined with high D. radicum density had a negative impact on foliar herbivore performance and parasitoid preference and performance. Plant volatiles and parasitoid preference were shown to decrease with drought stress and root herbivory. Plant foliar glucosinolate, nitrogen and carbon concentrations were significantly affected by drought stress. Relative water content and plant biomass were significantly affected by both stresses. The present study on a Brassica-aphid system underlines the importance of root herbivory and drought stress in mediating interactions between plant, foliar herbivores and their parasitoids. The implications of these findings for multitrophic interactions under potential climate change are discussed with particular reference to pest management.

description: Erdős, Gyárfás and Pyber showed that every $r$-edge-coloured complete graph $K_n$ can be covered by $25 r^2 \log r$ vertex-disjoint monochromatic cycles (independent of $n$). Here, we extend their result to the setting of binomial random graphs. That is, we show that if $p = p(n) = Ω(n^{-1/(2r)})$, then with high probability any $r$-edge-coloured $G(n,p)$ can be covered by at most $1000 r^4 \log r $ vertex-disjoint monochromatic cycles. This answers a question of Korándi, Mousset, Nenadov, Škorić and Sudakov.

description: Gray blight, caused by Pestalotiopsis-like species, is one of the most serious diseases in tea [Camellia sinensis (L.) O. Kuntze] production. In this study, eight Pestalotiopsis isolates obtained from diseased tea leaves collected in Chongqing, China were identified as P. chamaeropis Maharachch, K.D. Hyde & Crous. Pestalotiopsis chamaeropis as a causal agent of tea gray blight disease was clearly distinguished from other species in the genus Pestalotiopsis by morphological characteristics and phylogenetic analysis based on a combination of the internal transcribed spacer (ITS), beta-tubulin (β-tubulin), and partial translation elongation factor 1-alpha (TEF) genes. Pathogenicity was confirmed by inoculation of a conidial suspension of P. chamaeropis on wounded tea leaves. Difenoconazole, a highly active and low toxicity fungicide, demonstrated significant antifungal effect towards P. chamaeropis, with an EC50 of 0.470 µg/mL.
