description: We present an 870 $μ$m continuum survey of 300 protostars from the Herschel Orion Protostar Survey using the Atacama Compact Array (ACA). These data measure protostellar flux densities on envelope scales $\leq$8000 au (20") and resolve the structure of envelopes with 1600 au (4") resolution, a factor of 3-5 improvement in angular resolution over existing single-dish 870 $μ$m observations. We compare the ACA observations to Atacama Large Millimeter/submillimeter Array 12 m array observations at 870 $μ$m with $\sim$0.1 (40 au) resolution. Using the 12 m data to measure the fluxes from disks and the ACA data within 2500 au to measure the combined disk plus envelope fluxes, we calculate the 12 m/ACA 870 $μ$m flux ratios. Our sample shows a clear evolution in this ratio. Class 0 protostars are mostly envelope-dominated with ratios $<$0.5. In contrast, Flat Spectrum protostars are primarily disk-dominated with ratios near 1, although with a number of face-on protostars dominated by their envelopes. Class I protostars span the range from envelope to disk-dominated. The increase in ratio is accompanied by a decrease in the envelope fluxes and estimated mass infall rates. We estimate that 80$\%$ of the mass is accreted during the envelope-dominated phase. We find that the 12 m/ACA flux ratio is an evolutionary indicator that largely avoids the inclination and foreground extinction dependence of spectral energy distribution-based indicators.

description: In this letter we study the dynamics of a first order phase transition from nucleonic to quark matter in neutron stars. Using standard equations of state for these two phases we find the density range where such a transition is possible. Then we study the transformation of the star assuming that the quark core is formed via a spherical shock wave. The thermodynamical conditions in the quark core are found from the conservation laws across the transition region. Their dependence on the density and velocity of the incoming nuclear matter are studied. It is found that the shock is especially violent in the beginning of the conversion process when the velocity of the infalling matter is especially high. As the shock propagates further from the center the front velocity first increases and reaches a maximum value when the incoming velocity is around $0.2$. Finally, the front velocity quickly goes to zero when incoming matter velocity approaches zero. We have shown that the density and pressure jumps are especially large in the begining of the transition process.

description: Flowers of Murraya paniculata were assessed for production of phenolic secondary metabolites and were found to yield temporally variable concentrations of total phenolics and flavonoids due to enzymatic regulation by L-phenylalanine ammonia lyase. Maximum yield of phenolics was obtained from partly open flowers, with esterified hydroxycinnamic acids (mainly ferulic acid) forming the major component. Scopoletin-a coumarin product of ferulic acid - was isolated consistently from senescent flowers by High Performance Liquid Chromatography (HPLC). Approximately 200 mg of fresh floral tissue extracted with one millilitre solvent (methanol:water :: 30:70) yielded up to 1.6 mg of ferulic acid and 40 μg of scopoletin from partly open (at 18:00 h) and senescent (at 06:00 h) blooms respectively. Along with other hydroxycinnamic acid and coumarin components of M. paniculata flowers detected by HPLC, o-coumaric acid and isoauraptene were identified by Gas Chromatography-Mass Spectrometry. Various free-radical scavenging assays revealed the ferulic acid fraction to have stronger antioxidant activities than the scopoletin fraction, but no antibiotic activity was detected for ferulic acid. Total antioxidant capacities of ferulic acid and scopoletin fractions were estimated to be 9% and 7.8% of that of ascorbic acid standard, respectively. Scopoletin fraction exhibited Minimum Inhibitory Concentrations at 0.585 mg.mL-1 against Bacillus subtilis and 1.372 mg.mL-1 against Escherichia coli. The high concentrations of these bioactive phenylpropanoids in such a common flower species presents potential application in low-risk crop protection and plant-based nutraceuticals.

description: Reflectionless CMV matrices are studied using scattering theory. By changing a single Verblunsky coefficient a full-line CMV matrix can be decoupled and written as the sum of two half-line operators. Explicit formulas for the scattering matrix associated to the coupled and decoupled operators are derived. In particular, it is shown that a CMV matrix is reflectionless iff the scattering matrix is off-diagonal which in turn provides a short proof of an important result of [Breuer-Ryckman-Simon]. These developments parallel those recently obtained for Jacobi matrices.

In particular, we improve Emery Thomas' explicit upper bounds on the number of solutions to this equation. For instance, when $n \geqslant 219$, we show that there are no more than 32 integer pair solutions to this equation when $n$ is odd and no more than 40 integer pair solutions to this equation when $n$ is even, an improvement on Thomas' work, where he shows that there are no more than 38 such solutions when $n$ is odd and no more than 48 such solutions when $n$ is even.

It lists the donors, acceptors, as well as related characteristic features of tetrel bonds that are commonly observed in the crystalline phase and/or that emerge from first principles calculations in the solid-state and gas phases. These may be used to identify, char-acterize and classify the unique subset of inter- and intramolecular interactions formed by the elements of Group 14 of the Periodic Table that possess an electrophilic site in a molecular entity.

description: In the already identified quantitative trait loci (QTL), modulating Hb F levels are cis-acting haplotypes of the β-globin gene cluster itself, although the single nucleotide polymorphisms (SNPs) accounting more for the association, remain uncertain. In this study, the role in Hb F production of previously reported candidate SNPs within the β-globin gene cluster was reexamined, along with a yet poorly studied variation in the BGLT3 gene. In a sample of β-thalassemia (β-thal) carriers, we succeeded in replicating the significant association between increased Hb F levels and rs7482144 (C>T) (HBG2 XmnI), which is the most well-established variation in the cluster influencing the trait. This SNP was found to be in strong linkage disequilibrium (LD) with a variation in the HBBP1 gene [rs10128556 (G>A)], which consistently revealed a similar association signal. Remarkably, much stronger than the latter associations were those involving both rs968857 (T allele) (3' HBBP1) and rs7924684 (G allele) (BGLT3), two SNPs that were also in strong LD. As the pattern of LD detected in the β-globin gene cluster does not correlate with a tight linkage between markers, complex interactions between SNPs at the cluster seem to modulate Hb F. Seeing that no such associations were detected in normal subjects, the question can be raised on whether, under erythropoiesis stress, epigenetic mechanisms contribute to change the regulation of the entire β-globin gene cluster. In conclusion, we provide statistical evidence for a new player within the β-globin gene cluster, BGLT3, that in cooperation with other regions influences Hb F levels in β-thal carriers.

description: We study the Mott phase of three-component bosons, with one particle per site, in an optical lattice by mapping it onto an SU(3) spin model. In the simplest case of full SU(3) symmetry, one obtains a ferromagnetic Heisenberg model. Introducing an SU(3) analog of spin-orbit coupling, additional spin-spin interactions are generated. We first consider the scenario of spin-dependent hopping phases, leading to Dzyaloshinskii-Moriya-type interactions. They result in the formation of spiral spin textures, which in one dimension can be understood by a local unitary transformation. Applying classical Monte Carlo simulations, we extend our study to two-dimensional systems, and systems with "true" spin-orbit coupling, involving spin-changing hoppings.

description: Neonatal calf diarrhoea is a multifactorial condition and a major cause of economic loss to producers. Several pathogens are reported to cause or contribute to calf diarrhoea. Other factors include environmental and management practices that influence disease outcomes. The study objective was to evaluate effect of colostrum source (CS) and calf breed (CB) on diarrhoea incidents in 51 spring born Holstein (HO; n=29, birth weight (BW) 34.7 (SE 0.69) kg) and Jersey (JE; n=22, BW 25.9 (SE 0.81) kg) heifer calves from birth (day (d) 0) to weaning (d83 (SE 1.04)). Calves were fed 8.5% BW in colostrum, from either, the calf’s dam (n=28) or a pooled source of colostrum (≤2 cows, ≤1d; n=23) within 2 hours of birth. A modified Wisconsin-Madison calf health scoring system was used and rectal temperature (RT) measured for clinical assessment at d0, d7, d21, and day-of-diarrhoea incident, and day-of-weaning. Live weights were recorded at d0, d21, and weaning. Diarrhoea incident was assessed using faecal scores (0=normal, 1=semi-formed, 2=moderate, 3=severe diarrhoea), and health status was defined as calves having diarrhoea (n=27), or healthy (n=24). Faecal scores were analysed using the Wilcoxon Mann-Whiney U-test and RT data were analysed using the PROC MIXED procedure in SAS (9.4). The model included CS, CB, and health status and their interactions as fixed effects, and shed as random effect. The mean day post-birth for diarrhoea was d23 (SE 1.04) and d22 (SE 0.88) for HO and JE calves, respectively; 53% of calves had a diarrhoea incident. There was no CS × CB interaction (P>0.05) for diarrhoea incident from d0 to W. On the day of diarrhoea detection, faecal scores were greater (P<0.0001) for diarrhoeic calves (median score 3; range 2-3) than healthy calves (0; 0-1) while RT of diarrhoeic calves was elevated (+0.37°C (SE 0.01); P=0.004). Health status had no effect (P>0.05) on ADG from d0 to weaning. Faecal samples from healthy and diarrhoeic calves at d7, d21 and the day-of-diarrhoea incident, and day-of-weaning are currently undergoing microbial metataxonomic analysis using 16s rRNA amplicon sequencing

description: Superconducting nanowires are very important due to their applications ranging from quantum technology to astronomy. In this work, we implement a non-invasive process to fabricate nanowires of high-$T_\text{c}$ superconductor Bi$_2$Sr$_2$CaCu$_2$O$_{8+δ}$ (BSCCO). We demonstrate that our nanowires can be used as bolometers in the visible range with very high responsivity of 9.7 $\times$ 10$^{3}$ V/W. Interestingly, in a long (30 $μ$m) nanowire of 9 nm thickness and 700 nm width, we observe bias current-dependent localized spots of maximum photovoltage. Moreover, the scalability of the bolometer responsivity with the normal state resistance of the nanowire could allow further performance improvement by increasing the nanowire length in a meander geometry. We observe phase slip events in nanowires with small cross-sections (12 nm thick, 300 nm wide, and 3 $μ$m long) at low temperatures. Our study presents a scalable method for realizing sensitive bolometers working near the liquid-nitrogen temperature.

description: We have used polarized Raman scattering to probe lattice vibrations and charge ordering in 12 nm thick, epitaxially strained PrNiO$_3$ films, and in superlattices of PrNiO$_3$ with the band-insulator PrAlO$_3$. A carefully adjusted confocal geometry was used to eliminate the substrate contribution to the Raman spectra. In films and superlattices under tensile strain, which undergo a metal-insulator transition upon cooling, the Raman spectra reveal phonon modes characteristic of charge ordering. These anomalous phonons do not appear in compressively strained films, which remain metallic at all temperatures. For superlattices under compressive strain, the Raman spectra show no evidence of anomalous phonons indicative of charge ordering, while complementary resonant x-ray scattering experiments reveal antiferromagnetic order associated with a modest increase in resistivity upon cooling. This confirms theoretical predictions of a spin density wave phase driven by spatial confinement of the conduction electrons.

The Palaces of Comfort, Consolation and Distraction - The Pie and Mash shop as a performative space of a contested London working class memory
Creators: name: Freedman, Stuart
Publisher: name: University of Westminster
Year: 2023

description: This thesis seeks to interrogate and clarify the history and culture of London’s traditional but fading and largely forgotten eel, pie and mash shops. In doing so the work examines their cultural conduit, the adjacent and evolving identity of the cockney whose contested memoryscapes have, I suggest, great contemporary political and cultural relevance in an age of populism and Brexit. The work excavates a tracing around the shops’ absences in historical literature. It situates their establishment within the dying breath of an older, popular street culture and the birth of a new London working class, centred around unofficial street markets and in a synchronous dance with the ideological accession of the bourgeoisie. The thesis employs the biological notion of a taxon to illustrate the shops’ evolution largely defined by the class-demotion of their clientele that mirrored the changing cartography of the city. By the late nineteenth century, this work argues, the eel and pie shops had become a pillar of a respectable London working class culture whose hyper-local solidarities revolved around micro-class divisions of work and negotiated bourgeois codes of propriety as part of a ‘culture of consolation’ that has remained largely impenetrable to outsiders. The study explores this concomitant cockney identity which became, partly through bourgeois theatrical ventriloquising, a figure of imperial incorporation. This eventually came to represent a particular type of ‘ordinariness’, subsequently reconfigured around the gains of a Welfare State and a national economy that continues to be periodically valorised according its usefulness to capital at times of political stress. Utilising sensory ethnography and memory studies the work explores the landscape and territoriality of the contemporary eel, pie and mash shop. It interrogates the rituals and complex, often competing and polyphonic memory inscriptions which memorialise a largely post-colonial nostalgic melancholia around the loss of fantasy of a British omnipotence. The thesis argues that the shops and their simulacra-like reincarnations amongst the cockney diaspora in the Essex new towns offer an insight into the changing notions of taste and class within the convivialities of a unique but broadly closed heritage of proletarian culture as a zone of resistance in the neoliberal city.

description: Realistic computational models of the peripheral auditory system can assist researchers in better understanding how sensorineural hearing loss (SNHL) affects sound coding. Here we adapted a one-dimensional (1-D) human nonlinear cochlear transmission line model [Verhulst et al., Hearing Research, 360, 55-75 (2018)] to mouse and gerbil models, aiming to facilitate cross-species research on SNHL. We modified key model parameters such as cochlear length and height based on species-specific anatomical data. The characteristic frequency range and the sampling frequency of each model were adjusted to correspond to the tonotopic map of each animal. The pole trajectories of the local basilar membrane (BM) admittance were calibrated to reproduce realistic cochlear tuning and compressive behavior. The models were assessed by comparing BM and auditory nerve output along with simulated distortion-product otoacoustic emissions (DPOAE) to data and recordings from mice and gerbils. The mouse model closely mirrors the observed data trends in both tuning characteristics and DPOAE responses. However, in gerbils, thresholds in the lower frequency range were higher than expected, suggesting areas for further refinement. Moreover, both human and gerbil DPOAEs exhibited fluctuations that require further investigation. In addition to providing a new tool auditory research in mice and gerbils, extending the transmission-line model from human to common laboratory animals is beneficial for a more thorough testing of the computational approach given that direct pathophysiological SNHL data is available for these species.

description: Ho2Ir3Si5 belongs to the family of three-dimensional (3D) R2Ir3Si5 (R = Lu, Er and Ho) compounds that exhibit a colossal first-order charge density wave (CDW) transition where there is a strong orthorhombic-to-triclinic distortion of the lattice accompanied by superlattice reflections. The analysis by single-crystal X-ray diffraction (SXRD) has revealed that the Ir-Ir zigzag chains along c are responsible for the CDW in all three compounds. The replacement of the rare earth element from non-magnetic Lu to magnetic Er or Ho lowers TCDW, where TCDWLu = 200 K, TCDWEr = 150 K and TCDWHo = 90 K. Out of the three compounds, Ho2Ir3Si5 is the only system where second-order superlattice reflections could be observed, indicative of an anharmonic shape of the modulation wave. The CDW transition is observed as anomalies in the temperature dependencies of the specific heat, electrical conductivity and magnetic susceptibility, which includes a large hysteresis of 90 to 130 K for all measured properties, thus corroborating the SXRD measurements. Similar to previously reported Er2Ir3Si5, there appears to be a coupling between CDW and magnetism such that the Ho3+ magnetic moments are influenced by the CDW transition, even in the paramagnetic state. Moreover, earlier investigations on polycrystalline material revealed antiferromagnetic (AFM) ordering at TN = 5.1 K, whereas AFM order is suppressed and only the CDW is present in our highly ordered single-crystal. First-principles calculations predict Ho2Ir3Si5 to be a metal with coexisting electron and hole pockets at the Fermi level. The Ho and Ir atoms have spherically symmetric metallic-type charge density distributions that are prone to CDW distortion. Phonon calculations affirm that the Ir atoms are primarily responsible for the CDW distortion, which is in agreement with the experiment.

description: In this contribution to Light Cone 2014, three average transverse momentum quantities are discussed: the Sivers shift, the dijet imbalance, and the $p_T$ broadening. The definitions of these quantities involve integrals over all transverse momenta that are overly sensitive to the region of large transverse momenta, which conveys little information about the transverse momentum distributions of quarks and gluons inside hadrons. TMD factorization naturally suggests alternative definitions of such integrated quantities, using Bessel-weighting and rapidity cut-offs, with the conventional definitions as limiting cases. The regularized quantities are given in terms of integrals over the TMDs of interest that are well-defined and moreover have the advantage of being amenable to lattice evaluations.

description: Dispersion curves of elastic waveguides exhibit points where the group velocity vanishes while the wavenumber remains finite. These are the so-called zero-group-velocity (ZGV) points. As the elastodynamic energy at these points remains confined close to the source, they are of practical interest for nondestructive testing and quantitative characterization of structures. These applications rely on the correct prediction of the ZGV points. In this contribution, we first model the ZGV resonances in anisotropic plates based on the appearance of an additional modal solution. The resulting governing equation is interpreted as a two-parameter eigenvalue problem. Subsequently, we present three complementary numerical procedures capable of computing ZGV points in arbitrary nondissipative elastic waveguides in the conventional sense that their axial power flux vanishes. The first method is globally convergent and guarantees to find all ZGV points but can only be used for small problems. The second procedure is a very fast, generally-applicable, Newton-type iteration that is locally convergent and requires initial guesses. The third method combines both kinds of approaches and yields a procedure that is applicable to large problems, does not require initial guesses and is likely to find all ZGV points. The algorithms are implemented in "GEW ZGV computation" (doi: 10.5281/zenodo.7537442).

description: MRP RNA is a noncoding RNA component of RNase mitochondrial RNA processing (MRP), a multi-protein eukaryotic endoribonuclease reported to function in multiple cellular processes, including ribosomal RNA processing, mitochondrial DNA replication, and cell cycle regulation. A recent study predicted a potential Drosophila ortholog of MRP RNA (CR33682) by computer-based genome analysis. We have confirmed the expression of this gene and characterized the phenotype associated with this locus. Flies with mutations that specifically affect MRP RNA show defects in growth and development that begin in the early larval period and end in larval death during the second instar stage. We present several lines of evidence demonstrating a role for Drosophila MRP RNA in rRNA processing. The nuclear fraction of Drosophila MRP RNA localizes to the nucleolus. Further, a mutant strain shows defects in rRNA processing that include a defect in 5.8S rRNA processing, typical of MRP RNA mutants in other species, as well as defects in early stages of rRNA processing.

description: We experimentally study the spin dynamics of mesoscopic ensembles of ultracold magnetic spin-3 atoms located in two separated wells of an optical dipole trap. We use a radio-frequency sweep to selectively flip the spin of the atoms in one of the wells, which produces two separated spin domains of opposite polarization. We observe that these engineered spin domains are metastable with respect to the long-range magnetic dipolar interactions between the two ensembles. The absence of inter-cloud dipolar spin-exchange processes reveals a classical behavior, in contrast to previous results with atoms loaded in an optical lattice. When we merge the two subsystems, we observe spin-exchange dynamics due to contact interactions which enable the first determination of the s-wave scattering length of 52Cr atoms in the S=0 molecular channel a_0=13.5^{+11}_{-10.5}a_B (where a_B is the Bohr radius).

description: We compute the exact retarded Green's functions in thermal $CFT$s with chemical potential and angular momenta using holography respectively. We consider the field equations satisfied by the quasi-normal modes in both charged and rotating black holes in $AdS$ spacetime and mapped them to the Heun equations by appropriate changes of variables. The AGT correspondence allows us to find the connection formulae among the solutions of the Heun equations near different singularities by using the crossing relations of the five-point correlators in the Liouville $CFT$. The connection formulae associated with the boundary conditions imposed on the bulk field equations yield the exact thermal correlators in the boundary $CFT$.

description: Tetrad-based generalized complex formalism by Majorana--Oppenheimer is applied to treat electromagnetic field in extending de Sitter Universe in on-static spherically-symmetric coordinates. With the help of Wigner D-functions, we separate angular dependence in the complex vector field E_{j}(t,r)+i B_{j}(t,r) from (t,r)-dependence. The separation parameter arising here instead of frequency ωin Minkowski space-time is quantized, non-static geometry of the de Sitter model leads to definite dependence of electromagnetic modes on the time variable. Relation of 3-vector complex approach to 10-dimensional Duffin-Kemmer-Petiau formalism is considered. On this base, the electromagnetic waves of magnetic and electric type have been constructed in both approaches. In Duffin-Kemmer-Petiau approach, there are constructed gradient-type solutions in Lorentz gauge.

description: Tertiary structure prediction is important for understanding structure–function relationships for RNAs whose structures are unknown and for characterizing RNA states recalcitrant to direct analysis. However, it is unknown what root-mean-square deviation (RMSD) corresponds to a statistically significant RNA tertiary structure prediction. We use discrete molecular dynamics to generate RNA-like folds for structures up to 161 nucleotides (nt) that have complex tertiary interactions and then determine the RMSD distribution between these decoys. These distributions are Gaussian-like. The mean RMSD increases with RNA length and is smaller if secondary structure constraints are imposed while generating decoys. The compactness of RNA molecules with true tertiary folds is intermediate between closely packed spheres and a freely jointed chain. We use this scaling relationship to define an expression relating RMSD with the confidence that a structure prediction is better than that expected by chance. This is the prediction significance, and corresponds to a P-value. For a 100-nt RNA, the RMSD of predicted structures should be within 25 Å of the accepted structure to reach the P ≤ 0.01 level if the secondary structure is predicted de novo and within 14 Å if secondary structure information is used as a constraint. This significance approach should be useful for evaluating diverse RNA structure prediction and molecular modeling algorithms.

description: We introduce a class of ultra-light and ultra-stiff sandwich panels designed for use in photophoretic levitation applications and investigate their mechanical behavior using both computational analyses and micro-mechanical testing. The sandwich panels consist of two face sheets connected with a core that consists of hollow cylindrical ligaments arranged in a honeycomb-based hexagonal pattern. Computational modeling shows that the panels have superior bending stiffness and buckling resistance compared to similar panels with a basketweave core, and that their behavior is well described by Uflyand-Mindlin plate theory. By optimizing the ratio of the face sheet thickness to the ligament wall thickness, panels maybe obtained that have a bending stiffness that is more than five orders of magnitude larger than that of a solid plate with the same area density. Using a scalable microfabrication process, we demonstrate that panels as large as 3x3 cm^2 with a density of 20 kg/m^3 can be made in a few hours. Micro-mechanical testing of the panels is performed by deflecting microfabricated cantilevered panels using a nanoindenter. The experimentally measured bending stiffness of the cantilevered panels is in very good agreement with the computational results, demonstrating exquisite control over the dimensions, form, and properties of the microfabricated panels.

description: Rare genetic disorders affect more than 6% of the global population. Reaching a diagnosis is challenging because rare disorders are very diverse. Many disorders have recognizable facial features that are hints for clinicians to diagnose patients. Previous work, such as GestaltMatcher, utilized representation vectors produced by a DCNN similar to AlexNet to match patients in high-dimensional feature space to support "unseen" ultra-rare disorders. However, the architecture and dataset used for transfer learning in GestaltMatcher have become outdated. Moreover, a way to train the model for generating better representation vectors for unseen ultra-rare disorders has not yet been studied. Because of the overall scarcity of patients with ultra-rare disorders, it is infeasible to directly train a model on them. Therefore, we first analyzed the influence of replacing GestaltMatcher DCNN with a state-of-the-art face recognition approach, iResNet with ArcFace. Additionally, we experimented with different face recognition datasets for transfer learning. Furthermore, we proposed test-time augmentation, and model ensembles that mix general face verification models and models specific for verifying disorders to improve the disorder verification accuracy of unseen ultra-rare disorders. Our proposed ensemble model achieves state-of-the-art performance on both seen and unseen disorders.

description: Relativistic equations of Bethe-Salpeter type for hadron structure are most conveniently formulated in momentum space. The presence of confining interactions causes complications because the corresponding kernels are singular. This occurs not only in the relativistic case but also in the nonrelativistic Schrödinger equation where this problem can be studied more easily. For the linear confining interaction the singularity reduces to one of Cauchy principal value form. Although this singularity is integrable, it still makes accurate numerical solutions difficult. We show that this principal value singularity can be eliminated by means of a subtraction method. The resulting equation is much easier to solve and yields accurate and stable solutions. To test the method's numerical efficiency, we performed a three-parameter least-squares fit of a simple linear-plus-Coulomb potential to the bottomonium spectrum.

Optimised graded metamaterials for mechanical energy confinement and amplification via reinforcement learning

description: A reinforcement learning approach to design optimised graded metamaterials for mechanical energy confinement and amplification is described. Through the proximal policy optimisation algorithm, the reinforcement agent is trained to optimally set the lengths and the spacing of an array of resonators. The design optimisation problem is formalised in a Markov decision problem by splitting the optimisation procedure into a discrete number of decisions. Being the physics of graded metamaterials governed by the spatial distribution of local resonances, the space of possible configurations is constrained by using a continuous function for the resonators arrangement. A preliminary analytical investigation has been performed to characterise the dispersive properties of the analysed system by treating it as a locally resonant system. The outcomes of the optimisation procedure confirms the results of previous investigations, highlighting both the validity of the proposed approach and the robustness of the systems of graded resonators when employed for mechanical energy confinement and amplification. The role of the resonator spacing is shown to be secondary with respect to the resonator lengths or, in other words, with respect to the oscillation frequencies of the resonators. However, it is also demonstrated that reducing the number of resonators can be advantageous. The outcomes related to the joint optimisation of the resonator lengths and spacing, thanks also to the adaptive control of the analysis duration, overcome significantly the performance of previously known systems by working almost uniquely on enlarging the time in which the harvester oscillations take place without amplifying these oscillations. The proposed procedure is suitable to be applied to a wide range of design optimisation problems in which the effect of the design choices can be assessed through numerical simulations.
