description: Viticulture is one of the major horticultural industries of the world, with the area of grapevines cultivated exceeding 7.9 million hectare. The grapevines belong to the family Vitaceae, which are mostly woody, tree-climbing vines, though a few have a shrubby growth habit. They have tendrils and inflorescences opposite the leaves. The grapevine fruit is used in a wide variety of products, ranging through fresh fruit, preserves, juice, wine and raisins. This review paper attempts to address a potential Asian Vitis species, as there was no sufficient information and most of the species were ignored in modern viticulture and enology. Vitis amurensis, Vitis heyneana, Vitis davidii, and Vitis yeshanensis are the most common and most popular species in Asia. The Vitis genus contains more than 70 species, with centres of origin in South Europe, Asia Minor, East Asia, and North and Central America. Asia is one of the major gene centres of origin for more than 37 Vitis species. Asian Vitis species have strong resistance against such diseases like Anthracnose, Ripe Rot, Powdery Mildew, Crown Gall and they can withstand environmental stress. Their germplasms can easily be crossed with V. vinifera and American Vitis species. Additionally, the berries of Asian wild Vitis species do not have the undesirable “foxy” flavour compounds commonly existing in the berries of American Vitis species. As the European grapevines are not well tolerant to different diseases, Asian wild Vitis have captured scientists and breeders’ attention in the grapevine breeding and wine industry.

description: We show that several qubits can be integrated in a single magnetic ion, using its internal electronic spin states with energies tuned by a suitably chosen molecular environment. This approach is illustrated with a nearly-isotropic Gd(III) ion entrapped in a polyoxometalate molecule. Experiments with microwave technologies, either three dimensional cavities or quantum superconducting circuits, show that this magnetic molecule possesses the number of spin states and the set of coherently addressable transitions connecting these states that are needed to perform a universal three-qubit processor or, equivalently, a d=8-level 'qudit'. Our findings open prospects for developing more sophisticated magnetic molecules which can result in more powerful and noise resilient quantum computation schemes.

description: We report the discovery of EPIC201702477b, a transiting brown dwarf in a long period (40.73691 +/- 0.00037 day) and eccentric (e=0.2281 +/- 0.0026) orbit. This system was initially reported as a planetary candidate based on two transit events seen in K2 Campaign 1 photometry and later validated as an exoplanet. We confirm the transit and refine the ephemeris with two subsequent ground-based detections of the transit using the LCOGT 1m telescope network. We rule out any transit timing variations above the level of 30s. Using high precision radial velocity measurements from HARPS and SOPHIE we identify the transiting companion as a brown dwarf with a mass, radius, and bulk density of 66.9 +/- 1.7 M$_J$, 0.757 +/- 0.065 R$_J$, and 191+/-51 g.cm$^{-3}$ respectively. EPIC201702477b is the smallest radius brown dwarf yet discovered, with a mass just below the H-burning limit. It has the highest density of any planet, substellar mass object or main-sequence star discovered so far. We find evidence in the set of known transiting brown dwarfs for two populations of objects - high mass brown dwarfs and low mass brown dwarfs. The higher-mass population have radii in very close agreement to theoretical models, and show a lower-mass limit around 60 M$_J$. This may be the signature of mass-dependent ejection of systems during the formation process.

description: We have studied the polarized image of an equatorial emitting ring around a rotating black hole surrounded by a cold dark matter (CDM) halo. Results show that the CDM halo density has the similar effects of the halo's characteristic radius on the polarized image for the black hole. The effects of the CDM halo on the polarized image depend on the magnetic field configuration, the fluid velocity and the observed inclination. With the increase of the CDM halo parameters, the observed polarization intensity decreases when the magnetic field lies in equatorial plane, but in the case where the magnetic field is perpendicular to the equatorial plane, the change of the observed polarization intensity with CDM halo also depends on the position of the emitting point in the ring. The change of the electric vector position angle (EVPA) with the CDM halo becomes more complicated. Our results also show that the influence of the CDM halo on the polarized image is generally small, which are consistent with the effects of dark matter halo on black hole shadows. These results could help to further understand dark matter from black hole images.

description: When a planet passes in front of a starspot during a transit of its host star, it causes a small upward blip in the light curve. Modelling the transit with the starspot allows the size, brightness and position of the spot to be measured. If the same spot can be observed in two different transits, it is possible to track the motion of the spot due to the rotation of the star. The rotation period and velocity of the star (Prot and Vsini) and the sky-projected orbital obliquity of the system (lambda) can then be determined. If one has three or more observations of the same spot, the true orbital obliquity (psi) can be measured. We are performing this analysis for a number of cool stars orbited by transiting planets. We present our results so far and compile a catalogue of lambda and psi measurements from spot crossing events. The method is particularly useful for cool stars, and is therefore complementary to studies of the Rossiter-McLaughlin effect, which perform better on hotter and faster-rotating stars.

description: The quality of irrigation water directly influences the quality of soil and the crops grown in the soil. Quality of water used for agricultural purposes is directly proportional to the yield. The present study was conducted to find the quality of Gungua Badiya river water and its usability for agricultural purposes in Abaya district, West Gujji Zone, Oromiya Region, Ethiopia. To analyze the physicochemical parameters of the river water, nine samples were collected from upper, middle and lower parts of the river. The physicochemical parameters are analyzed to explore the usability of the river water are: pH, Electrical conductivity (EC), Total dissolved solids (TDS), Calcium (Ca2+), Magnisium (Mg2+), Sodium ( Na+), Chloride (Cl- ) and Residual Sodium Carbonate (RSC), Sodium adsorption ratio (SAR) and Soluble Sodium Percent (SSP). After evaluating the parameters, it is found that the river

description: In Ethiopia, rural-urban migration has been visibly dominated by the mobility of the youth. Scholarly works in the area have exhaustively identified the prominent causes as well as effects of this pattern of mobility. By going beyond the push-pull categorization, this study comparatively examines the role of social networks in the migration decision of young rural-urban migrants. Precisely, revealing the nexus between social networks, migrants’ perceptions of their home, and destination, vis-à-vis migration decision has been the concern of this inquiry. The study being of a qualitative type, interview and focus group discussion were employed as the main instruments of data collection. Having adopted a purposive sampling design, participants of the study were selected by using snowball and quota sampling techniques.

description: Probability of coincidental clustering among the orbits of comets, asteroids and meteoroids depends on many factors like: the size of the orbital sample searched for clusters or the size of the identified group, it is different for groups of 2,3,4, ... members. Probability of coincidental clustering is assessed by the numerical simulation, therefore, it depends also on the method used for the synthetic orbits generation. We tested the impact of some of these factors. For a given size of the orbital sample we have assessed probability of random pairing among several orbital populations of different sizes. We have found how these probabilities vary with the size of the orbital samples. Finally, keeping fixed size of the orbital sample we have shown that the probability of random pairing can be significantly different for the orbital samples obtained by different observation techniques. Also for the user convenience we have obtained several formulae which, for given size of the orbital sample, one can use to calculate the similarity threshold corresponding to the small value of the probability of coincidental similarity among two orbits.

description: We propose subspace methods for 3-parameter eigenvalue problems. Such problems arise when separation of variables is applied to separable boundary value problems; a particular example is the Helmholtz equation in ellipsoidal and paraboloidal coordinates. While several subspace methods for 2-parameter eigenvalue problems exist, their extensions to three parameter setting seem to be challenging. An inherent difficulty is that, while for 2-parameter eigenvalue problems we can exploit a relation to Sylvester equations to obtain a fast Arnoldi type method, such a relation does not seem to exist when there are three or more parameters. Instead, we introduce a subspace iteration method with projections onto generalized Krylov subspaces that are constructed from scratch at every iteration using certain Ritz vectors as the initial vectors. Another possibility is a Jacobi--Davidson type method for three or more parameters, which we generalize from its 2-parameter counterpart. For both approaches, we introduce a selection criterion for deflation that is based on the angles between left and right eigenvectors. The Jacobi--Davidson approach is devised to locate eigenvalues close to a prescribed target, yet it often also performs well when eigenvalues are sought based on the proximity of one of the components to a prescribed target. The subspace iteration method is devised specifically for the latter task. The proposed approaches are suitable especially for problems where the computation of several eigenvalues is required with high accuracy. Matlab implementations of both methods have been made available in the package MultiParEig.

description: Typically, a production of a particle with a small transverse momentum in hadron-hadron collisions is described by CSS-based TMD factorization at moderate Bjorken $x_B\sim 1$ and by $k_T$-factorization at small $x_B$. A uniform description valid for all $x_B$ is provided by rapidity-only TMD factorization developed in a series of recent papers at the tree level. In this paper the rapidity-only TMD factorization for particle production by gluon fusion is extended to the one-loop level.

description: At the heart of convex geometry lies the observation that the volume of convex bodies behaves as a polynomial. Many geometric inequalities may be expressed in terms of the coefficients of this polynomial, called mixed volumes. Among the deepest results of this theory is the Alexandrov-Fenchel inequality, which subsumes many known inequalities as special cases. The aim of this note is to give new proofs of the Alexandrov-Fenchel inequality and of its matrix counterpart, Alexandrov's inequality for mixed discriminants, that appear conceptually and technically simpler than earlier proofs and clarify the underlying structure. Our main observation is that these inequalities can be reduced by the spectral theorem to certain trivial `Bochner formulas'.

description: We investigate the photo-induced spin dynamics of single nitrogen-vacancy (NV) centres in diamond near the electronic ground state level anti-crossing (GSLAC), which occurs at an axial magnetic field around 1024 G. Using optically detected magnetic resonance spectroscopy, we first find that the electron spin transition frequency can be tuned down to 100 kHz for the \NV{14} centre, while for the \NV{15} centre the transition strength vanishes for frequencies below about 2 MHz owing to the GSLAC level structure. Using optical pulses to prepare and readout the spin state, we observe coherent spin oscillations at 1024 G for the \NV{14}, which originate from spin mixing induced by residual transverse magnetic fields. This effect is responsible for limiting the smallest observable transition frequency, which can span two orders of magnitude from 100 kHz to tens of MHz depending on the local magnetic noise. A similar feature is observed for the \NV{15} centre at 1024 G. As an application of these findings, we demonstrate all-optical detection and spectroscopy of externally-generated fluctuating magnetic fields at frequencies from 8 MHz down to 500 kHz, using a \NV{14} centre. Since the Larmor frequency of most nuclear spin species lies within this frequency range near the GSLAC, these results pave the way towards all-optical, nanoscale nuclear magnetic resonance spectroscopy, using longitudinal spin cross-relaxation.

description: ELIXIR-IT, the Italian Node of ELIXIR, gathers most of the leading Italian research institutions in the field of life sciences. It consists of a vast and heterogeneous community of scientists that develop, maintain and provide a large set of resources and services, such as databases, software tools, training, computing power and data storage.
The ELIXIR-IT Training Platform (TP), thanks to a team of qualified and motivated researchers and training experts, designs, develops and delivers activities closely in line with the ELIXIR training programme established in Europe, taking charge of the entire management process. In particular, the ELIXIR-IT TP co-leads the “Train the Trainer” programme within the ELIXIR Project Plan 2019-2023, and actively promotes Software and Data Carpentry workshops and the building of a “The Carpentries” community within ELIXIR. The TP collaborates with the ELIXIR Tool Platform on defining strategies for the adoption of best practices for research software development, including drafting a Software Management Plan for the ELIXIR community; it also participates in several projects with other ELIXIR Nodes.
In order to meet international and local needs, the ELIXIR-IT TP provides training for both researchers, developers and trainers, thus promoting the growth of a community of highly qualified scientists and instructors, who can transmit their bioinformatics knowledge, skills and abilities with efficiency and effectiveness, in a virtuous cycle of sharing with the entire scientific community. This approach, which takes advantage of state-of-the-art teaching and learning techniques, has led to the establishment of a successful training programme, which includes practical short-term intensive courses, workshops, bio-hackathons, “Train the Trainer” and eLearning events, as well as a series of activities for high-school students and teachers, actions for the industry sector, and a wide range of scientific dissemination initiatives.
All activities are monitored through quality and impact indicators and assessment strategies, the outcomes of which are helping identify strengths and weaknesses of the ELIXIR-IT training programme. Future challenges include scaling up face-to-face and eLearning training offerings whilst ensuring their full sustainability and ever-increasing quality.

description: Transitive proxy voting (or "liquid democracy") is a novel form of collective decision making, often framed as an attractive hybrid of direct and representative democracy. Although the ideas behind liquid democracy have garnered widespread support, there have been relatively few attempts to model it formally. This paper makes three main contributions. First, it proposes a new social choice-theoretic model of liquid democracy, which is distinguished by taking a richer formal perspective on the process by which a voter chooses a proxy. Second, it examines the model from an axiomatic perspective, proving (a) a proxy vote analogue of May's Theorem and (b) an impossibility result concerning monotonicity properties in a proxy vote setting. Third, it explores the topic of manipulation in transitive proxy votes. Two forms of manipulation specific to the proxy vote setting are defined, and it is shown that manipulation occurs in strictly more cases in proxy votes than in classical votes.

description: The radio-frequency (RF) system is the key element that generates electric fields for beam acceleration. To keep the system reliable, a highly sophisticated protection scheme is required, which also should be designed to ensure a good balance between beam availability and machine safety. Since RF systems are complex, incorporating high-voltage and high-power equipment, a good portion of machine downtime typically comes from RF systems. Equipment and component damage in RF systems results in long and expensive repairs. Protection of RF system hardware is one of the oldest machine protection concepts, dealing with the protection of individual high-power RF equipment from breakdowns. As beam power increases in modern accelerators, the protection of accelerating structures from beam-induced faults also becomes a critical aspect of protection schemes. In this article, an overview of the RF system is given, and selected topics of failure mechanisms and examples of protection requirements are introduced.

description: Topological phases of spin liquids with constrained disorder can host a kinetics of fractionalized excitations. However, spin-liquid phases with distinct kinetic regimes have proven difficult to observe experimentally. Here we present a realization of kagome spin ice in the superconducting qubits of a quantum annealer, and use it to demonstrate a field-induced kinetic crossover between spin-liquid phases. Employing fine control over local magnetic fields, we show evidence of both the Ice-I phase and an unconventional field-induced Ice-II phase. In the latter, a charge-ordered yet spin-disordered topological phase, the kinetics proceeds via pair creation and annihilation of strongly correlated, charge conserving, fractionalized excitations. As these kinetic regimes have resisted characterization in other artificial spin ice realizations, our results demonstrate the utility of quantum-driven kinetics in advancing the study of topological phases of spin liquids.

description: In a seminal paper "Volumen und Oberfläche" (1903), Minkowski introduced the basic notion of mixed volumes and the corresponding inequalities that lie at the heart of convex geometry. The fundamental importance of characterizing the extremals of these inequalities was already emphasized by Minkowski himself, but has to date only been resolved in special cases. In this paper, we completely settle the extremals of Minkowski's quadratic inequality, confirming a conjecture of R. Schneider. Our proof is based on the representation of mixed volumes of arbitrary convex bodies as Dirichlet forms associated to certain highly degenerate elliptic operators. A key ingredient of the proof is a quantitative rigidity property associated to these operators.

description: We investigate the fossil magnetic field in the accretion and protoplanetary discs using the Shakura and Sunyaev approach. The distinguishing feature of this study is the accurate solution of the ionization balance equations and the induction equation with Ohmic diffusion, magnetic ambipolar diffusion, buoyancy and the Hall effect. We consider the ionization by cosmic rays, X-rays and radionuclides, radiative recombinations, recombinations onto dust grains, and also thermal ionization. The buoyancy appears as the additional mechanism of magnetic flux escape in the steady-state solution of the induction equation. Calculations show that Ohmic diffusion and magnetic ambipolar diffusion constraint the generation of the magnetic field inside the `dead' zones. The magnetic field in these regions is quasi-vertical. The buoyancy constraints the toroidal magnetic field strength close to the disc inner edge. As a result, the toroidal and vertical magnetic fields become comparable. The Hall effect is important in the regions close to the borders of the `dead' zones because electrons are magnetized there. The magnetic field in these regions is quasi-radial. We calculate the magnetic field strength and geometry for the discs with accretion rates $(10^{-8}-10^{-6})\,\rm{M}_{\odot}\,\rm{yr}^{-1}$. The fossil magnetic field geometry does not change significantly during the disc evolution while the accretion rate decreases. We construct the synthetic maps of dust emission polarized due to the dust grain alignment by the magnetic field. In the polarization maps, the `dead' zones appear as the regions with the reduced values of polarization degree in comparison to those in the adjacent regions.

description: We investigate the electronic dispersion and transport properties of graphene/WSe$_{2}$ heterostructures in the presence of a proximity induced spin-orbit coupling (SOC) using a low-energy Hamiltonian, with different types of symmetry breaking terms, obtained from a four-band, first and second nearest-neighbour tight-binding (TB) one. The competition between different perturbation terms leads to inverted SOC bands. Further, we study the effect of symmetry breaking terms on ac and dc transport by evaluating the corresponding conductivities within linear response theory. The scattering-independent part of the valley-Hall conductivity, as a function of the Fermi energy $E_{F}$, is mostly negative in the ranges $-λ_{R}\leqslant E_{F}$ and $E_{F}\geqslantλ_{R}$ when the strength $λ_{R}$ of the Rashba SOC increases except for a very narrow region around $E_{F}=0$ in which it peaks sharply upward. The scattering-dependent diffusive conductivity increases linearly with electron density, is directly proportional to $λ_{R}$ in the low- and high-density regimes, but weakens for $λ_{R}=0$. We investigate the optical response in the presence of a SOC-tunable band gap for variable $E_{F}$. An interesting feature of this SOC tuning is that it can be used to switch on and off the Drude-type intraband response. Furthermore, the ac conductivity exhibits interband responses due to the Rashba SOC. We also show that the valley-Hall conductivity changes sign when $E_F$ is comparable to $λ_R$ and vanishes at higher values of $E_F$. It also exhibits a strong dependence on temperature and a considerable structure as a function of the frequency.

description: The latest analysis of the cosmic microwave background by the Planck team finds more smoothing of the acoustic peaks in the temperature power spectrum than predicted by $Λ$CDM. Here we investigate whether this additional smoothing can be mimicked by an oscillatory feature, generated during inflation, that is similar to the acoustic peaks but out of phase. We consider oscillations generated by oscillating modulations of the background -- e.g., due to heavy fields or modulated potentials -- and by sharp features. We show that it is difficult to induce oscillations that are linear (or almost linear) in $k$ by oscillatory modulations of the background. We find, however, that a sharp bumpy feature in the sound speed of perturbations is able to produce the desired oscillations. The scenario can be tested by combining CMB and BAO data.

title: The Visual Culture of Haunting in Post Colonial Korea

description: My thesis explores the history and psychology of the Minjoong (grassroots) Realist Art and Culture Movement which emerged during the democratisation period in South Korea in the 1980s and early 1990s. Following territorial decolonization and 35 years of rapid industrialisation led by the military dictatorial regime, the 1980s and the 1990s marked a time of insurgence of popular antagonism against the regime and the dominant norms of society which had repressed the expressions of the grassroots people in the society. I examine how the emergent culture -a 'visual culture of haunting' - is instigated and formed by numerous haunted subjects and the return of repressed memories. This culture is marked by works of Lim Oksang and Oh Yoon who materialised the ghosts of the minjoong, who had long been repressed by "silencing structure" and "culture of forgetting" of Korean society. They actively dealt with the personal and historical trauma and haunting imagination of a future as part of the incorporation process of the internal images of "the Real". The 'Real' translates the irreducible core of memory and imagination of the minjoong which has previously unrepresented. I also explore how the repressed and silenced "subaltern" groups in Korean modem history, especially the former sexual slave women, have gradually come into the historical light providing their testimonies in this emergent cultural and political milieu. I point out the significant role of feminist intellectuals and artists who are committed to the resolution of the women's issues. For instance, their repressed voices are facilitated, reactualised and materialised through an art therapy workshop set up by a young artist, Lee Kyungsin, and documentary-making set up by the young film maker Byun Youngjoo. The paintings of former sexual slavery victims, Kang Dukkyung and Kim Sukduk, as well as Byun's documentaries, Nazen Mosori I and 2, witness the innermost voices and life performances of these women, who were previously constrained by their own personalised shame and the negativity of Han (long repressed grievance).

description: Consider the following variational problem: among all curves in $\mathbb{R}^n$ of fixed length with prescribed end points and prescribed tangents at the end points, minimise the $L^\infty$-norm of the curvature. We show that the solutions of this problem, and of a generalised version, are characterised by a system of differential equations. Furthermore, we have a lot of information about the structure of solutions, which allows a classification.

description: Radio observations of young stellar objects (YSOs) enable the study of ionised plasma outflows from young protostars via their free-free radiation. Previous studies of the low-mass young system T Tau have used radio observations to model the spectrum and estimate important physical properties of the associated ionised plasma (local electron density, ionised gas content and emission measure). However, without an indication of the low-frequency turnover in the free-free spectrum, these properties remain difficult to constrain. This paper presents the detection of T Tau at 149 MHz with the Low Frequency Array (LOFAR) - the first time a YSO has been observed at such low frequencies. The recovered total flux indicates that the free-free spectrum may be turning over near 149 MHz. The spectral energy distribution is fitted and yields improved constraints on local electron density ($(7.2 \pm 2.1)\times10^{3}$ cm$^{-3}$), ionised gas mass ($(1.0 \pm 1.8)\times10^{-6}$ M$_{\odot}$) and emission measure ($(1.67 \pm 0.14)\times10^5$ pc cm$^{-6}$).

Valley-controlled transport in graphene/ WSe$_{2}$ heterostructures under an off-resonant polarized light

description: We investigate the electronic dispersion and transport properties of graphene/WSe$_{2}$ heterostructures in the presence of a proximity-induced spin-orbit coupling $λ_{v}$, sublattice potential $Δ$, and an off-resonant circularly polarized light of frequency $Ω$ that renormalizes $Δ$ to $\barΔ_{ηp} = Δ+ηp Δ_Ω $ with $η$ and $p$ the valley and polarization indices, respectively, and $ Δ_Ω $ the gap due to the off-resonant circularly polarized light. Using a low-energy Hamiltonian we find that the interplay between different perturbation terms leads to inverted spin-orbit coupled bands. At high $Ω$ we study the band structure and dc transport using the Floquet theory and linear response formalism, respectively. We find that the inverted band structure transfers into the direct band one when the off-resonant light is present. The valley-Hall conductivity behaves as an even function of the Fermi energy in the presence and absence of this light. At $Δ_Ω$ = $λ_{v}$ - $Δ$ a transition occurs from the valley-Hall phase to the anomalous Hall phase. In addition, the valley-Hall conductivity switches sign when the polarization of the off-resonant light changes. The valley polarization vanishes for $Δ_Ω$ = 0 but it is finite for $Δ_Ω$ $\neq$ 0 and reflects the lifting of the valley degeneracy of the energy levels, for $Δ_Ω \neq 0$, when the off-resonant light is present. The corresponding spin polarization, present for $Δ_Ω$ = 0, increases for $Δ_Ω$ $\neq$ 0. Further, pure $K$ or $K^{\prime}$ valley polarization is generated when $Δ_Ω$ changes sign. Also, the charge Hall conductivity is finite for $Δ_Ω\neq 0$ and changes sign when the handedness of the light polarization changes.
Two statistical regimes in the transition to filamentation

description: We experimentally investigate fluctuations in the spectrum of ultrashort laser pulses propagating in air, close to the critical power for filamentation. Increasing the laser peak power broadens the spectrum while the beam approaches the filamentation regime. We identify two regimes for this transition: In the center of the spectrum, the output spectral intensity increases continuously. In contrast, on the edges of the spectrum the transition implies a bimodal probability distribution function for intermediate incident pulse energies, where a high-intensity mode appears and grows at the expense of the original low-intensity mode. We argue that this dual behavior prevents the definition of a univoquial threshold for filamentation, shedding a new light on the long-standing lack of explicit definition of the boundary of the filamentation regime.

description: A nonlinear analogue of the Rademacher type of a Banach space was introduced in classical work of Enflo. The key feature of Enflo type is that its definition uses only the metric structure of the Banach space, while the definition of Rademacher type relies on its linear structure. We prove that Rademacher type and Enflo type coincide, settling a long-standing open problem in Banach space theory. The proof is based on a novel dimension-free analogue of Pisier's inequality on the discrete cube.

Many-objective Optimization via Voting for Elites

description: Real-world problems are often comprised of many objectives and require solutions that carefully trade-off between them. Current approaches to many-objective optimization often require challenging assumptions, like knowledge of the importance/difficulty of objectives in a weighted-sum single-objective paradigm, or enormous populations to overcome the curse of dimensionality in multi-objective Pareto optimization. Combining elements from Many-Objective Evolutionary Algorithms and Quality Diversity algorithms like MAP-Elites, we propose Many-objective Optimization via Voting for Elites (MOVE). MOVE maintains a map of elites that perform well on different subsets of the objective functions. On a 14-objective image-neuroevolution problem, we demonstrate that MOVE is viable with a population of as few as 50 elites and outperforms a naive single-objective baseline. We find that the algorithm's performance relies on solutions jumping across bins (for a parent to produce a child that is elite for a different subset of objectives). We suggest that this type of goal-switching is an implicit method to automatic identification of stepping stones or curriculum learning. We comment on the similarities and differences between MOVE and MAP-Elites, hoping to provide insight to aid in the understanding of that approach $\unicode{x2013}$ and suggest future work that may inform this approach's use for many-objective problems in general.
