description: The CLIC Tracker Detector (CLICTD) is a monolithic pixelated sensor chip produced in a $180$ nm imaging CMOS process built on a high-resistivity epitaxial layer. The chip, designed in the context of the CLIC tracking detector study, comprises a matrix of ${16\times128}$ elongated pixels, each measuring ${300\times30}$ $μ$m$^2$. To ensure prompt charge collection, every elongated pixel is segmented in eight sub-pixels, each containing a collection diode and a separate analog front-end. A simultaneous $8$-bit time measurement with $10$ ns time bins and $5$-bit energy measurement with programmable range is performed in the on-pixel digital logic. The main design aspects as well as the first results from laboratory measurements with the CLICTD chip are presented.

To imitate all that is hidden. The place of mimesis in Adorno’s theory of musical performance
Creators: name: Cecchi, Alessandro
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2017

description: The article examines the use of the concept of mimesis in Adorno’s notes towards a theory of musical performance. In trying to idiosyncratically define the latter as “reproduction”, Adorno relied on a framework elaborating on concepts introduced by Arnold Schoenberg, Hugo Riemann and Walter Benjamin – a framework that the article discusses insofar as it deals with the problem of mimesis. Specific attention is devoted to the relation between Benjamin’s essays on language and translation and Adorno’s theory of notation, that soon became the crucial aspect of his theory of reproduction. Given the shortcomings of Adorno’s theory, which in the end did not achieve its goals, the article proposes to capitalize on his terminology while at the same time rethinking his framework in the light of recent musicological paradigms for the study of musical performance. On the whole, the article shows that it was Adorno’s philosophical assumptions – in particular the theses of music’s non-intentionality and of its non-similarity to language – that prevented him from convincingly theorizing musical performance, and suggests an alternative framework for future research.

Algorithms for predicting the secondary structure of pairs and combinatorial sets of nucleic acid strands
Creators: name: Andronescu, Mirela Ştefania
Publisher: name: University of British Columbia
Year: 2009

description: Secondary structure prediction of nucleic acid molecules is a very important problem in computational molecular biology. In this thesis we introduce two new algorithms for: (1) secondary structure prediction of pairs of nucleic acid molecules (PairFold), and (2) finding which sequences, formed from a combinatorial set of nucleic acid strands, have the most stable secondary structures (CombFold). Our algorithms run in polynomial time in the sequences lengths and are extensions of the free energy minimization algorithm [72] for secondary structure prediction without pseudoknots, using the nearest neighbour thermodynamic model. Predicting hybridization of pairs of molecules is motivated by important applications such as ribozyme - mRNA target duplexes, primer binding prediction and DNA code design. Finding the most stable concatenations in combinatorial sets of strands is useful for SELEX experiments and for testing whether sets in DNA computing or tag libraries concatenate without secondary structure. Our results for PairFold predictions show over 80% accuracy for sequences of up to 100 nucleotides. The performance goes down as the sequences increase in length and as the number of non-canonical base pairs, pseudoknots and tertiary interactions, none of these considered here, increases. The accuracy of CombFold is similar to that of the free energy minimization algorithm for single strands, being just a polynomial method for structure prediction of a combinatorial set of strands. We show that although complex, CombFold can quickly predict large concatenations of sets drawn from the literature. In the future, these two algorithms can be combined to predict the most stable duplexes formed by two combinatorial sets.
From Abbild to Bild? Depiction and Resemblance in Husserl’s Phenomenology
Creators: name: Rozzoni, Claudio
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2017

description: In a well-known course he gave in 1904-1905, Edmund Husserl developed a ‘threefold’ notion of image revolving around the notion of depiction [Abbildung]. More specifically, the phenomenological description allows a seeing-in to emerge as an essential characteristic of the image consciousness, in which an image object assumes the role of a representant [Repräsentant] in order to allow us to see the image subject in the image itself (thanks to “moments of resemblance” shared by image object and image subject). Nevertheless, our paper – focusing particularly on what might be called the depictive art par excellence, that is the portrait – aims to show that it would be erroneous to read the Husserlian notion of image exclusively on the basis of this earlier course: things seem to change significantly when Husserl develops a different notion of phantasy, and artistic images, in particular, are not to be thought of as resembling something else, but rather as expressive images producing their own model.

On pion correction to quark mass in next-leading order of mean-field expansion in NJL model

description: The correction to quark mass are calculated in Nambu-Jona-Lasinio model with 4-dimensional cutoff regularization and with dimensional-analytical regularization in the next-to-leading order of mean-field expansion. The analytical calculations show that the pion correction to quark mass is equal to zero. Comparing the results in both regularizations one can signify that the zero value of the pion correction to quark mass is the regularization-independent fact of Nambu-Jona-Lasinio model.

description: We study the recent \XeT excess in context of solar scalar, specifically in the framework of Higgs-portal and the relaxion model. We show that $m_ϕ= 1.9\,\keV$ and $g_{ϕe}=2.4\times 10^{-14}$ can explain the observed excess in science run 1 (SR1) analysis in the 1-7 keV range. When translated into the scalar-Higgs mixing angle, the corresponding mixing angle $\sinθ= 10^{-8}$ is intriguingly close to the maximum value of mixing angle for the technical naturalness of the scalar mass. Unlike the solar axion model, the excess favors a massive scalar field because of its softer spectrum. In the minimal scenarios we consider, the best fit parameters are in tension with stellar cooling bounds. We discuss a possibility that a large density of red giant stars may trigger a phase transition, resulting in a local scalar mass increase suppressing the stellar cooling. For the particular case of minimal relaxion scenarios, we find that such type of chameleon effects is automatically present but they can not ease the cooling bounds. They are however capable of triggering a catastrophic phase transition in the entire universe. Following this observation we derive a new set of bounds on the relaxed-relaxion parameter space.

description: We calculate the contribution of unscreened and screened scalar and vector potential electron acoustic phonon coupling to resistivity in disordered graphene through Keldysh Greens function method within the diffusive limit. We obtain analytical results in the asymptotic limits of clean and strong impurities for both DP and VP coupling, which is in observed to be in good agreement with the resistivity behavior in these limits. We find that the complete numerical results approach the analytical result in the extreme limits, but give different temperature dependencies in between these limits. The graphene resistivity has been investigated as functions of temperature, mean free path and carrier density. We also evaluated the screened behavior in the Thomas Fermi and Random phase approximation dielectric function and obtained the temperature power exponents. We find that in the absence of screening when the electronic disorder is less than the critical disoeder limit, the two coupling mechanisms are affected differently and the relaxation rate associated with the VP coupling is suppressed by disorder as compared to the DP coupling, and the DP coupling is enhanced by disorder.

description: We study ground state properties of the double-exchange model on triangle chain in the classical limit on $t_{2g}$ spins. The ground state is determined by a competition among the kinetic energy of the $e_g$ electron, the antiferromagnetic exchange energy between the $t_{2g}$ spins, and frustration due to a geometric structure of the lattice. The phase diagrams are obtained numerically for two kinds of the models which differ only in the transfer integral being real or complex. The properties of the states are understood from the viewpoint of the spin-induced Peierls instability. The results suggest the existence of a chiral glass phase which is characterized by a local spin chirality and a continuous degeneracy.

description: We present a method to numerically compute accurate tunnelling rates for a Bose-Einstein condensate which is described by the nonlinear Gross-Pitaevskii equation. Our method is based on a sophisticated real-time integration of the complex-scaled Gross-Pitaevskii equation, and it is capable of finding the stationary eigenvalues for the Wannier-Stark problem. We show that even weak nonlinearities have significant effects in the vicinity of very sensitive resonant tunnelling peaks, which occur in the rates as a function of the Stark field amplitude. The mean-field interaction induces a broadening and a shift of the peaks, and the latter is explained by analytic perturbation theory.

Ideality in Theatre. Or a reverse evolution of mimesis from Plato to Diderot

Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2017

description: This paper deals with a development of the ancient thought on mimesis in its modern reception as regards a certain idea of theatre. It defends the hypothesis that the figure of the character, as set up in Diderot’s Paradoxe sur le comédien, has its source in a curious reversal of the Platonic mimesis. After presenting the main tenets of Plato’s reflection on mimesis and of Diderot’s theory on character, showing their convergences and contrasts, it is analyzed how such a conceptual turnaround has historically taken place, by establishing a chain of reception from Plato to Diderot passing through Cicero and the Renaissance artists.

description: What is a toy? As objects of play, toys seem to be inextricably bound up with mimesis: a child plays ‘make believe’, for example, with a doll or toy cart. But as I will show, Plato has a very different conception of toys from the modern one which tends to conceive of play as essentially mimetic. Toys do not derive their pleasure from being mimetic objects; rather, they are essentially pleasure objects and as such only incidentally mirror the objects of a ‘serious’ or ‘real’ world.

title: Exploring the implications of climate trends and extreme weather events for species conservation in Mauritius
Creators: name: Taylor, Joseph
Publisher: name: University of Reading
Year: 2019

description: Species conservation is expected to become more challenging in a changing climate, and this may be most acute in the speciose tropics, where species are generally adapted to a narrow temperature range from which novel climates are projected to emerge this century. Island endemic species are expected to show particularly low adaptive capacity. Yet, climate change vulnerability assessments are constrained by a shortage of detailed and long-term datasets, uncertainty over the impacts of extreme events, and poor understanding of implications for tropical animal phenology. These knowledge gaps limit our capacity to design management strategies to alleviate the impacts of future climate risks. This thesis explores these issues for species in Mauritius, where successful recovery programmes have involved the collection of detailed individual-based datasets. Long-term climate trends, including for extremes, were quantified for areas of high conservation importance. Detailed analyses were carried out into climate impacts on the breeding phenology and demography of the Mauritius kestrel (Falco punctatus) and echo parakeet (Psittacula eques). Climate trend analyses reveal local-scale variation in long-term trends, with nearby populations of conservation concern under different pressures from changes in rainfall. Detailed analysis for the Mauritius kestrel shows that its breeding phenology is tracking shifts in a seasonal climate window. Individual birds show plasticity in response to temperature increases, despite the effects of a severe population bottleneck. In contrast, echo parakeets show maladaptive adjustments to climate variability, with delayed breeding in drier years increasing exposure to tropical cyclones. Cyclones appear to mediate reproductive senescence, but this risk is reduced through the re-scheduling of breeding by supplementary food provision. Based on these results, vulnerability assessments and management plans for restricted-range species, such as those endemic to tropical islands, should incorporate local-scale climate trends, meteorological indices for extremes, and analysis of phenology and temporal exposure to climate risks.

description: We study $\mathrm{AdS}_3\times S^3/\mathbb{Z}_k\times {\tilde S}^3/\mathbb{Z}_{k'}$ solutions to M-theory preserving $\mathcal{N}=(0,4)$ supersymmetries, arising as near-horizon limits of M2-M5 brane intersections ending on M5'-branes, with both types of five-branes placed on A-type singularities. Solutions in this class asymptote locally to $\mathrm{AdS}_7/\mathbb{Z}_k\times {\tilde S}^3/\mathbb{Z}_{k'}$, and can thus be interpreted as holographic duals to surface defect CFTs within the $\mathcal{N}=(1,0)$ 6d CFT dual to this solution. Upon reduction to Type IIA, we obtain a new class of solutions of the form $\mathrm{AdS}_3\times S^3/\mathbb{Z}_k\times S^2 \times Σ_2$ preserving (0,4) supersymmetries. We construct explicit 2d quiver CFTs dual to these solutions, describing D2-D4 surface defects embedded within the 6d (1,0) quiver CFT dual to the $\mathrm{AdS}_7/\mathbb{Z}_k$ solution to massless IIA. Finally, in the massive case, we show that the recently constructed $\mathrm{AdS}_3\times S^2\times \mathrm{CY}_2$ solutions with $\mathcal{N}=(0,4)$ supersymmetries gain a defect interpretation when $\mathrm{CY}_2=T^4$ as surface CFTs originating from D2-NS5-D6 defects embedded within the 5d CFT dual to the Brandhuber-Oz $\mathrm{AdS}_6$ background.

description: The kinetic energy variation of emitted light clusters has been employed as a clock to explore the time evolution of the temperature for thermalizing composite systems produced in the reactions of 26A, 35A and 47A MeV $^{64}$Zn with $^{58}$Ni, $^{92}$Mo and $^{197}$Au. For each system investigated, the double isotope ratio temperature curve exhibits a high maximum apparent temperature, in the range of 10-25 MeV, at high ejectile velocity. These maximum values increase with increasing projectile energy and decrease with increasing target mass. The time at which the maximum in the temperature curve is reached ranges from 80 to 130 fm/c after contact. For each different target, the subsequent cooling curves for all three projectile energies are quite similar. Temperatures comparable to those of limiting temperature systematics are reached 30 to 40 fm/c after the times corresponding to the maxima, at a time when AMD-V transport model calculations predict entry into the final evaporative or fragmentation stage of de-excitation of the hot composite systems. Evidence for the establishment of thermal and chemical equilibrium is discussed.

Multi-scale summaries of temporal trajectories
Creators: name: Yang, Ruiyao
Publisher: name: University of British Columbia
Year: 2009

description: Existing studies on time series and temporal trajectories focus on similarity matching and indexing. In this thesis, we argue that for large collections of trajectories, it is useful to provide the functionality of summarization. We envisage a multi-scale framework within which the user is first presented with low-resolution summaries of the underlying trajectories. The user is then allowed to "zoom in" to get high-resolution summaries. We propose two types of summaries: s-summaries and p-summaries. S-summaries are generated based on the probabilistic distribution of the trajectories in the data set, essentially representing the more "typical" trajectories in the data set. In contrast, p-summaries tend to be exhaustive in having every trajectory represented. Both types of summaries rely critically on a summary structure we call a refinement matrix. For s-summaries, a binary tree of 2-dimensional refinement matrices is constructed for multi-scale browsing. For p-summaries, only a single higher-dimensional matrix is needed. Our experimental results show that: (i) the construction of these matrices at compile-time, (ii) the generation of both types of summaries at run-time, and (iii) the refinement of summaries at run-time can all be done efficiently. Finally, we show that the summaries are robust. That is, even if the data set grows significantly, the summaries may not need to be re-computed.

Dramatic Mimesis and Civic Education in Aristotle, Cicero and Renaissance Humanism

Year: 2017

description: This paper wants to address the Aristotelian analysis of the concept of mimesis from a social and cultural angle. It is going to show that mimesis is crucial if we want to understand why the institution of the theatre played such a crucial role in the civic educational programme of classical Athens. The paper’s argument is that the magic spell of theatrical imitation, its aesthetic machinery was exploited by the city for civic educational function. Dramas, and in particular tragedies helped to articulate the city’s political expectations from the citizens, and they achieved it with far better efficiency than any other medium of propaganda which was available in those days. It will first reconstruct the duality within the internal structure of the Aristotelian account of mimesis in Poetics: it will show both 1.) the aesthetic and 2.) the socio-cultural dimensions of his theory of civic initiation through dramatic imitation. In the second part it will compare this Greek cultural context with a similar context in Rome in the activity and writings of Cicero. Finally, the paper presents the Renaissance republican context of early modern Europe, which also connected politico-moral education with the idea of mimesis.

description: The use of Wavefront Sensors (WFS) is nowadays fundamental in the field of instrumental optics. This paper discusses the principle of an original and recently proposed new class of WFS. Their principle consists in evaluating the slopes of the wavefront errors by means of varying density filters placed into the image plane of the tested optical system. The device, sometimes called 'optical differentiation WFS' is completed by a digital data-processing system reconstructing the wavefront from the obtained slopes. Various luminous sources of different wavelengths and spectral widths can be employed. The capacities of the method are discussed from the geometrical and Fourier optics points of view, then by means of numerical simulations showing that the ultimate accuracy can be well below lambda/10 and lambda/100 Peak-to-Valley (PTV) and RMS respectively, provided that certain precautions are taken.

description: The bispectrum can quantify the non-Gussianity present in the redshifted 21-cm signal produced by the neutral hydrogen (HI) during the epoch of reionization (EoR). Motivated by this, we perform a comprehensive study of the EoR 21-cm bispectrum using simulated signals. Given a model of reionization, we demonstrate the behaviour of the bispectrum for all unique triangles in $k$ space. For ease of identification of the unique triangles, we parametrize the $k$-triangle space with two parameters, namely the ratio of the two arms of the triangle ($n=k_2/k_1$) and the cosine of the angle between them ($\cosθ$). Furthermore, for the first time, we quantify the impact of the redshift space distortions (RSD) on the spherically averaged EoR 21-cm bispectrum in the entire unique triangle space. We find that the real space signal bispectra for small and intermediate $k_1$-triangles ($k_1 \leq 0.6 \,{\rm Mpc^{-1}}$) is negative in most of the unique triangle space. It takes a positive sign for squeezed, stretched and linear $k_1$-triangles, specifically for large $k_1$ values ($k_1 \geq 0.6 \,{\rm Mpc^{-1}}$). The RSD affects both the sign and magnitude of the bispectra significantly. It changes (increases/decreases) the magnitude of the bispectra by $50-100\%$ without changing its sign (mostly) during the entire period of the EoR for small and intermediate $k_1$-triangles. For larger $k_1$-triangles, RSD affects the magnitude by $100-200\%$ and also flips the sign from negative to positive. We conclude that it is important to take into account the impact of RSD for a correct interpretation of the EoR 21-cm bispectra.

description: We measured the angular rotation and proper motion of the Triangulum Galaxy (M33) with the Very Long Baseline Array by observing two H2O masers on opposite sides of the galaxy. By comparing the angular rotation rate with the inclination and rotation speed, we obtained a distance of 730 +/- 168 kiloparsecs. This distance is consistent with the most recent Cepheid distance measurement. M33 is moving with a velocity of 190 +/- 59 km/s relative to the Milky Way. These measurements promise a new method to determine dynamical models for the Local Group and the mass and dark matter halos of M31, M33 and the Milky Way.

description: We propose a scalable photonic architecture for implementation of feedforward and recurrent neural networks to perform the classification of handwritten digits from the MNIST database. Our experiment exploits off-the-shelf optical and electronic components to currently achieve a network size of 16,384 nodes. Both network types are designed within the the reservoir computing paradigm with randomly weighted input and hidden layers. Using various feature extraction techniques (e.g. histograms of oriented gradients, zoning, Gabor filters) and a simple training procedure consisting of linear regression and winner-takes-all decision strategy, we demonstrate numerically and experimentally that a feedforward network allows for classification error rate of 1%, which is at the state-of-the-art for experimental implementations and remains competitive with more advanced algorithmic approaches. We also investigate recurrent networks in numerical simulations by explicitly activating the temporal dynamics, and predict a performance improvement over the feedforward configuration.

Study of the $Σ$(1385) and $Λ$(1405) resonances in K$^+$ photoproduction processes

description: The $γp \to K^+ π^0 Λ$ and $γp \to K^+ πΣ$ reactions are studied in the kinematic region where the $π^0 Λ$(1116) and $πΣ$(1192) pairs originate dominantly from the decay of the $Σ$(1385) and $Λ$(1405) resonances. We consider laboratory photon energies around 2 GeV, i.e. total center of mass energies above the known resonance region. We compute the t-channel kaon-exchange contribution to these reactions using $K^- p \to π^0 Λ$ and $K^- p \to πΣ$ amplitudes calculated in the framework of a chiral coupled-channel effective field theory of meson-baryon scattering. We extract from the calculated cross section the gauge-invariant double kaon pole term. We find this term to be large and likely to drive significantly the $γp \to K^+ π^0 Λ$ and $γp \to K^+ πΣ$ reactions in the kinematics under investigation. Accurate measurements of t-distributions for these processes, in progress or planned at ELSA and at SPring-8, are needed to confirm this expectation and assess the possibility of studying antikaon-nucleon dynamics just below threshold through these reactions.

description: Although France, Belgium and the Netherlands import a significant percentage of chilled fish fillet from Uganda, results suggest no significant degree of monopsony power is exercised by these countries. If Ugandan firms export to a few countries the competitive price should still prevail if there are many importing firms.

description: The LEP experiments have measured event shapes using data taken at e+e- center-of-mass energies ranging from 91 GeV to 209 GeV. Using the final LEP event shape measurements, a combined value of the strong coupling constant alpha_s(M_Z) has been extracted. Events with photon radiation have been used to extend the measurements to lower center-of-mass energies sqrt(s') to study the running of alpha_s. Alternative alpha_s measurements using four-jet rates have also been performed.

Seeing through Plato’s Looking Glass. Mythos and Mimesis from Republic to Poetics
Creators: name: Capra, Andrea
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2017

description: This paper revisits Plato’s and Aristotle’s views on mimesis with a special emphasis on mythos as an integral part of it. I argue that the Republic’s notorious “mirror argument” is in fact ad hominem: first, Plato likely has in mind Agathon’s mirror in Aristophanes’ Thesmoforiazusae, where tragedy is construed as mimesis; second, the tongue-in-cheek claim that mirrors can reproduce invisible Hades, when read in combination with the following eschatological myth, suggests that Plato was not committed to a mirror-like view of art; third, the very omission of mythos shows that the argument is a self-consciously one-sided one, designed to caricature the artists’ own pretensions of mirror-like realism. These points reinforce Stephen Halliwell’s claim that Western aesthetics has been haunted by a «ghostly misapprehension» of Plato’s mirror. Further evidence comes from Aristotle’s “literary” (as opposed to Plato’s “sociological”) discussion: rather than to the “mirror argument”, the beginning of the Poetics points to the Phaedo as the best source of information about Plato’s views on poetry.

Risk and Uncertainty

description: A non-parametric simulation model incorporating price risk determined gross revenue less risk management costs for cow-calf, winter stockering, and retained ownership scenarios for cattle producers in the Southeast. Risk management scenarios simulated hedging with commodity futures and purchasing at-the-money put options at alternative dates prior to the expected sales date.
Sensible schemes in aesthetic experience. Neuroaesthetics and transcendental philosophy compared

Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2017

description: My paper sets out to compare neuroaesthetics and transcendental philosophy, concerning the perception of schemes of imitation in aesthetic experience. The argument is structured in four steps: first, I will introduce the function of schemes in mirror-neuron-based processes and in general in the embodiment theory of Mark Johnson and George Lakoff; second, I will consider some analogical relations between a transcendental approach and neuroaesthetics concerning semantics; third, starting with the statement that one open question in neuroaesthetics is how creativity emerges, I would like to propose a transcendental account about sensible schemes as a possible foundation of creativity. I will conclude my paper with some examples from visual arts and aesthetic practices in general.

Stochastic Turbulent Acceleration in a fractal environment

description: We analyze the stochastic acceleration of particles inside a fully developed turbulent plasma. It is well known that large-amplitude magnetic fluctuations and coherent structures in such an environment obey a fractal scaling, and our specific aim is to study for the first time the effects of the fractality of these environments on stochastic acceleration. We have shown that an injected Maxwellian energy distribution is heated and forms a high energy tail in a very short time. Using standard parameters for the low solar corona, the injected Maxwellian distribution of electrons gets heated from the initial 100 eV to 10 KeV, and the power-law index of the high energy tail is about -2.3-4.0. The high energy tail starts around 100 keV, and reaches 10 MeV. The index of the power-law tail depends on the system size, and it is in good agreement with observed values for realistic system sizes. The heating and acceleration process is very fast (\sim 2 s). The reason why the acceleration time is so short is that the particles are trapped within small scale parts of the fractal environment, and their scattering mean free path reduces drastically. The presence of small scale activity also pulls easily particles from the thermal pool, so there is no need for a seed population. The mean square displacement in space and energy is superdiffusive for the high energy particles.

description: Using laser optical pumping, widths and frequency shifts are determined for microwave transitions between ground-state hyperfine components of $^{85}$Rb and $^{87}$Rb atoms contained in vapor cells with alkane anti-relaxation coatings. The results are compared with data on Zeeman relaxation obtained in nonlinear magneto-optical rotation (NMOR) experiments, a comparison important for quantitative understanding of spin-relaxation mechanisms in coated cells. By comparing cells manufactured over a forty-year period we demonstrate the long-term stability of coated cells, an important property for atomic clocks and magnetometers.

description: We expand a partial difference equation (P$Δ$E) on multiple lattices and obtain the P$Δ$E which governs its far field behaviour. The perturbative--reductive approach is here performed on well known nonlinear P$Δ$Es, both integrable and non integrable. We study the cases of the lattice modified Korteweg--de Vries (mKdV) equation, the Hietarinta equation, the lattice Volterra--Kac--Van Moerbeke (VKVM) equation and a non integrable lattice KdV equation. Such reductions allow us to obtain many new P$Δ$Es of the nonlinear Schrödinger (NLS) type.

Human mimicry and Imitation: the case of Biomimetics
Creators: name: Borsari, Andrea
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2017

description: Defining biomimetics (§ 1) as the imitation of models, systems and elements of nature for the purpose to solve human complex problems, the essay considers (§ 2) some examples of that activity, like display technologies, and nanoscientific innovations. According to the literature on the subject, the further section of the article (§ 3) examines the possibility of giving a conceptual framework for biomimetic processes, starting from the observation of its current insufficient development both on the logical level and on a wider philosophical one. The fourth section (§ 4) discusses the way through which an approach oriented to philosophical anthropology and recent perspectives on imitation can help us to understand this kind of phenomena at the intersection of human and (non-human) animal fields. In the final sections (§ 5), the text discusses the consequences of the biomimicry approach in the specific case of architecture and tries to draw some conclusions on the way an anthropology and an aesthetics of human mimicry and imitation can be re-shaped including biomimetics among their assumptions.
