description: Nowadays, video game developers record every virtual action performed by their players. As each player can remain in the game for years, this results in an exceptionally rich dataset that can be used to understand and predict player behavior. In particular, this information may serve to identify the most valuable players and foresee the amount of money they will spend in in-app purchases during their lifetime. This is crucial in free-to-play games, where up to 50% of the revenue is generated by just around 2% of the players, the so-called whales. To address this challenge, we explore how deep neural networks can be used to predict customer lifetime value in video games, and compare their performance to parametric models such as Pareto/NBD. Our results suggest that convolutional neural network structures are the most efficient in predicting the economic value of individual players. They not only perform better in terms of accuracy, but also scale to big data and significantly reduce computational time, as they can work directly with raw sequential data and thus do not require any feature engineering process. This becomes important when datasets are very large, as is often the case with video game logs. Moreover, convolutional neural networks are particularly well suited to identify potential whales. Such an early identification is of paramount importance for business purposes, as it would allow developers to implement in-game actions aimed at retaining big spenders and maximizing their lifetime, which would ultimately translate into increased revenue.
Attitudinal compounds in English
Creators: name: Charitonidis, Chariton
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 2017
Subjects: compounding; socio-expressive meaning; evaluative heads; stance; emotion; pejoration

description: This paper deals with the empirical validation of evaluative operations in English compounds first presented in Charitonidis (2014). The object of investigation are 103 English compounds expressing positive or negative stance, taken from Algeo's (1991) dictionary of neologisms. In the validation task, the valence (emotional positivity) ratings in Warriner, Kuperman and Brysbaert (2013) are used. The non-compositional patterns are explained with reference to the difference rate between the mean values of constituents and/or negative standard-deviation shifts in the evaluative heads.

Chewing Gum Degradation as an Environmental Awakening Tool
Creators: name: Nascimento, Daniela
Publisher: name: figshare
Year: 2019
Subjects: Environmental Chemistry

description: Many of the environmental impacts are caused by improper waste disposal, including those which are quickly consumed, such as chewing gum. The lack of information regarding the environmental problems caused by these materials is one of the issues which can be solved by Environmental Education. This pathway can make individuals aware of their responsibilities. In this sense, the present work aims to walk young students through several physical analysis which prove the degradation resistance of the chewing gum before and after undergoing the chewing process. Materials were studied along six months. During this period, a group of students followed the experiment, and they were able to conclude that chewing gun does not degrade quickly, drawing their attention to the Environmental cause.

Publisher: name: Zenodo
Year: 2024

description: This deliverable aims to provide the details of the final event organised for the public dissemination of the project outcomes and findings carried out by the Consortium (T6.1). Since the Möbius consortium is multidisciplinary, gathering industrial, artistic, social sciences and technological expertise, it was set that it would showcase its results in two of the largest cultural and technological events in Europe, Möbius Closing Event, explicitly focusing on the Frankfurt Book Fair 2023 (by MVB) and the Mobile World Congress Barcelona 2024 (by MWCapital).

The Frankfurt Book Fair is the most important international trade fair for publishing and content. Experts from global publishing meet partners from the technology industry and related creative industries such as film and games. Meanwhile, the Mobile World Congress Barcelona is the largest and most influential event for the connectivity ecosystem for global mobile operators, device manufacturers, technology providers, vendors, content owners, or professionals interested in the future of tech. Intense dissemination activities and rigorous impact assessment has been organised to maximise the impact of the results on the publishing industry and the European media ecosystem as a whole.

The primary objective of this report is to provide a comprehensive assessment of the events' outcomes and communication strategies employed. The report contextualises both events and offers detailed information about the two event communication plans created and executed before, during and after the events. It emphasises the significance of the project’s activities, such as panels, workshops, piloting activities and booths, in conveying the project's message and engaging the audience effectively, detailing which tools and channels were used.

description: The circuit model of a quantum computer consists of sequences of gate operations between quantum bits (qubits), drawn from a universal family of discrete operations. The ability to execute parallel entangling quantum gates offers clear efficiency gains in numerous quantum circuits as well as for entire algorithms such as Shor's factoring algorithm and quantum simulations. In cases such as full adders and multiple-control Toffoli gates, parallelism can provide an exponential improvement in overall execution time. More importantly, quantum gate parallelism is essential for the practical fault-tolerant error correction of qubits that suffer from idle errors. The implementation of parallel quantum gates is complicated by potential crosstalk, especially between qubits fully connected by a common-mode bus, such as in Coulomb-coupled trapped atomic ions or cavity-coupled superconducting transmons. Here, we present the first experimental results for parallel 2-qubit entangling gates in an array of fully-connected trapped ion qubits. We demonstrate an application of this capability by performing a 1-bit full addition operation on a quantum computer using a depth-4 quantum circuit. These results exploit the power of highly connected qubit systems through classical control techniques, and provide an advance toward speeding up quantum circuits and achieving fault tolerance with trapped ion quantum computers.
Negation in Bulgarian yes-no questions: Polarity items and negative concord

description: The paper addresses negation and Negative Concord in Bulgarian polar questions focusing on the distribution of the polarity items and the way they interact with the interrogative clitic li. Assuming that li functions as both interrogative and focus operator, I will observe a contrast in the licensing of Positive (PPIs) and Negative (NPIs) Polarity items related to their possibility of hosting the clitic. The contrast will be approached from the perspective of the relation between focus movement and the licensing of the NPIs. The paper furthermore addresses recent discussions on polar questions, namely Holmberg (2012) and Ambar (2013).

description: We construct the generating functional of two flavor chiral perturbation theory including the effects of virtual photons in the one loop approximation. As an application, we calculate the electromagnetic corrections to the elastic $ππ$ scattering amplitude, in particular to its S--wave threshold parameters. Numerical estimates are given for the reaction $π^0 π^0 \to π^0 π^0$. These electromagnetic effects are found to be smaller than the hadronic two-loop corrections for the scattering length $a_0$. The effective range $b_0$ increases by 36% due to the unitary cusp.

Reionization of the Universe induced by Primordial Black Holes

Subjects: subject: Astrophysics (astro-ph)

description: In this paper I will discuss the possibility of a reionization of the Universe due to the photons emitted by evaporating primordial black holes (PBHs); this process should happen during the last stages of the PBHs life, when the particle emission is very intense. I will study the time evolution of the ionization degree x, of the plasma temperature $T_{e}$ and of the photon number density $n_γ$ characterizing the Universe after the recombination epoch: a system of coupled differential equations for these variables is solved in an analytical way by assuming, as a photon source, PBHs having an initial mass $M\sim 10^{14}$ g. The results I obtain prove that such a kind of reionization is possible, being able to increase the ionization degree of the Universe from a value x=0.002 (just after the recombination) to values near 1 (when the black holes evaporation ends).

description: Lower limb loss is prevalent in the USA and world at large. Despite this, there are currently no commercially available bionic lower limb prosthesis which implement some kind of neuromuscular activity in their control. There are significant differences between different types of steps with regards to several factors such as ground reaction forces, stability and stance time length. As poor mobility is one of the leading reasons for lower limb prosthesis device abandonment, it is beneficial to develop a bionic lower limb prosthesis capable of providing suitable assistance depending on the nature of the step (backwards, forward, stair climbing, turns) to be completed. However, in order to achieve this there must first exist a reliable way to classify the nature of the step to be completed. Thus, this research will focus on the development of an EMG-based machine learning algorithm capable of identifying the nature of the next step during continuous walking. Surface Electromyography (sEMG) signals will be collected from four participants without disabilities that might affect gait. A weighted consensus model consisting of supervised machine learning algorithms will be constructed to identify the nature of the step using sEMG data from -40% to 80% of the gait cycle. Two methods for constructing the weighted consensus model will be considered – the first, a model that uses the top performing models of a specific subject in the final model for that subject and the second, a model which uses the best performing models on average. Two methods will also be considered for training the models, one where training is done individually per subject and one where all training set data is combined and concurrently used for training. Upon the conclusion of this research, it will be determined that the weighted consensus model identified is only capable of accurately classifying the step nature into stair descent, backwards waling and a third category consisting of turns, stair ascent and forward level walking. Future work should focus on the development of a cascading model which first applies the weighted consensus model identified in this research and then attempts to reclassify the steps belonging to the third category into their respective classes.

description: Intrinsic tunneling spectroscopy in high magnetic field ($H$) is used for a direct test of superconducting features in a quasiparticle density of states of high-$T_c$ superconductors. We were able to distinguish with a great clarity two co-existing gaps: (i) the superconducting gap, which closes as $H \to H_{c2}(T)$ and $T\to T_c(H)$, and (ii) the $c$-axis pseudo-gap, which does not change neither with $H$, nor $T$. Strikingly different magnetic field dependencies, together with previously observed different temperature dependencies of the two gaps ~\cite{Krasnov}, speak against the superconducting origin of the pseudo-gap.

Transits of Inclined Exomoons - Hide and Seek and an Application to Kepler-1625

description: A Neptune-sized exomoon candidate was recently announced by Teachey & Kipping, orbiting a 287 day gas giant in the Kepler-1625 system. However, the system is poorly characterized and needs more observations to be confirmed, with the next potential transit in 2019 May. In this Letter, we aid observational follow up by analyzing the transit signature of exomoons. We derive a simple analytic equation for the transit probability and use it to demonstrate how exomoons may frequently avoid transit if their orbit is larger than the stellar radius and sufficiently misaligned. The nominal orbit for the moon in Kepler-1625 has both of these characteristics, and we calculate that it may only transit roughly 40% of the time. This means that approximately six non-transits would be required to rule out the moon's existence at 95% confidence. When an exomoon's impact parameter is displaced off the star, the planet's impact parameter is displaced the other way, so larger planet transit durations are typically positively correlated with missed exomoon transits. On the other hand, strong correlations do not exist between missed exomoon transits and transit timing variations of the planet. We also show that nodal precession does not change an exomoon's transit probability and that it can break a prograde-retrograde degeneracy.

description: This study examines a potential relationship between reading and performance on a fluid intelligence test. Participants were 89 adults (M age= 39.0) of various educational backgrounds. Reading volume was assessed by the Greek versions of the Author and Magazine Recognition test (here ART-GR and MRT-GR respectively) initially developed by Stanovich and West (1989). Fluid intelligence was assessed by the Raven Progressive Matrices Test (Raven 1938), a non-verbal, graphical test. Participants with greater print exposure as measured both by the ART-GR and the MRT-GR reported greater fluid intelligence scores. The same was true for participants with more advanced than lower educational background.

Advanced Greek speakers of English responded to a questionnaire and completed three pronunciation tasks related to Greek identity and pronunciation. Subjects’ performance on pronunciation tasks was evaluated by three native English speakers. Findings indicate that Greek speakers dissociate their cultural identity from their preference for standard native/native-like models of English pronunciation.

description: Rigidity theory studies the properties of graphs that can have rigid embeddings in a euclidean space $\mathbb{R}^d$ or on a sphere and which in addition satisfy certain edge length constraints. One of the major open problems in this field is to determine lower and upper bounds on the number of realizations with respect to a given number of vertices. This problem is closely related to the classification of rigid graphs according to their maximal number of real embeddings. In this paper, we are interested in finding edge lengths that can maximize the number of real embeddings of minimally rigid graphs in the plane, space, and on the sphere. We use algebraic formulations to provide upper bounds. To find values of the parameters that lead to graphs with a large number of real realizations, possibly attaining the (algebraic) upper bounds, we use some standard heuristics and we also develop a new method inspired by coupler curves. We apply this new method to obtain embeddings in $\mathbb{R}^3$. One of its main novelties is that it allows us to sample efficiently from a larger number of parameters by selecting only a subset of them at each iteration. Our results include a full classification of the 7-vertex graphs according to their maximal numbers of real embeddings in the cases of the embeddings in $\mathbb{R}^2$ and $\mathbb{R}^3$, while in the case of $S^2$ we achieve this classification for all 6-vertex graphs. Additionally, by increasing the number of embeddings of selected graphs, we improve the previously known asymptotic lower bound on the maximum number of realizations. The methods and the results concerning the spatial embeddings are part of the proceedings of ISSAC 2018 (Bartzos et al, 2018).

description: Assessing students’ writing in the final year of Senior High School during the nationwide exams is of critical importance. Given the high stakes nature of many inter-rater inconsistencies, it is crucial that assessment criteria be guided by sound principles to ensure validity, fairness, and appropriacy to the context and purpose of assessment. In this light, the following article claims that if we redefine the frame associated with reliability and validity, we can develop assessment that leads to improvement of assessing teaching and learning. At the beginning, it offers a critical review of the relevant research followed by a framework for designing and developing writing assessment rubrics. Next, rubrics designed by the researchers are presented along with their theoretical basis.

description: We report the observation of spin domain walls bounded by half-quantum vortices (HQVs) in a spin-1 Bose-Einstein condensate with antiferromagnetic interactions. A spinor condensate is initially prepared in the easy-plane polar phase, and then, suddenly quenched into the easy-axis polar phase. Domain walls are created via the spontaneous $\mathbb{Z}_2$ symmetry breaking in the phase transition and the walls dynamically split into composite defects due to snake instability. The end points of the defects are identified as HQVs for the polar order parameter and the mass supercurrent in their proximity is demonstrated using Bragg scattering. In a strong quench regime, we observe that singly charged quantum vortices are formed with the relaxation of free wall-vortex composite defects. Our results demonstrate a nucleation mechanism for composite defects via phase transition dynamics.

description: This article attempts to describe the analysis of a written learner corpus of English in an effort to enhance the ‘Can Do’ statements describing the written production competence at the ‘Basic User’ level [Common European Framework of Reference for Languages (CEFR)]. The Sketch Engine software was used to analyze the Evosmos Learner Corpus (ELC) with respect to the use of the English past tense (PT). It will be shown that learners at the A1+/A2 level demonstrate a restricted use of the tense, writing primarily about themselves (“I”) and the people of their immediate family and/or environment, their thoughts and feelings. At the A2/A2+ level, the use of the tense is more widespread, as learners can talk about their pastimes and events in their lives, while, in discussing punctual incidents, they can also assume different viewpoints.

description: We investigate minimal energy solutions with vortices for an interacting Bose-Einstein condensate in a rotating trap. The atoms are strongly confined along the axis of rotation z, leading to an effective 2D situation in the x-y plane. We first use a simple numerical algorithm converging to local minima of energy. Inspired by the numerical results we present a variational Ansatz in the regime where the interaction energy per particle is stronger than the quantum of vibration in the harmonic trap in the x-y plane, the so-called Thomas-Fermi regime. This Ansatz allows an easy calculation of the energy of the vortices as function of the rotation frequency of the trap; it gives a physical understanding of the stabilisation of vortices by rotation of the trap and of the spatial arrangement of vortex cores. We also present analytical results concerning the possibility of detecting vortices by a time-of-flight measurement or by interference effects. In the final section we give numerical results for a 3D configuration.

It was found that both upper elementary and junior secondary students use more metacognitive strategies while they rarely employ cognitive strategies. However, the individual strategies used are different among the two age groups. The findings of this study suggest a number of implications for classroom activities promoting language learning strategy use.

description: Twelve Turkish-Greek bilingual learners of English were orally administered a translated version of the SILL questionnaire (Oxford 1990) and had to specify frequency of language learning strategy (LLS) use as well as confidence in the effectiveness of each strategy on a [01] bar instead of the usual Likert scales. Deviations between frequency and confidence in the results indicate that learners either appreciate the effectiveness of a strategy but they do not know how to use it or that they use a strategy without firmly believing in its usefulness, which suggests the need for pedagogical interventions to raise the learners’ awareness of language learning strategies and how to use them. More proficient learners exhibit higher frequency and confidence in reported LLS use than their less proficient peers, while the age of the learners does not seem to affect LLS use.

Can Nearby Resonances Enhance D^0 - anti-D^0 Mixing?

description: We consider the possibility that D^0 - anti-D^0 mixing undergoes resonant enhancement. Various scenarios are explored, including the potential effects of nearby pseudoscalar or scalar quark-antiquark (Q - anti-Q) resonances as well as of hybrid quark-antiquark-gluon Q - anti-Q G states. Assuming reasonable values for the resonance parameters we find relatively sizeable contributions from individual resonances to both Δm_D and ΔΓ_D. We derive a variant of the GIM cancellation mechanism for the resonance amplitudes and show that broken SU(3) can allow for sizeable residual effects. Additional input from meson spectroscopy and lattice gauge simulations will be needed to improve the accuracy of these predictions.

Spinal cord injury

description: Spinal cord injury is an aggression to the nerve bundles that causes total or partial loss of voluntary motricity and sensitivity, as well as impairment in the urinary, intestinal, circulatory, respiratory, sexual and reproductive systems. Rehabilitation is the way patients find to recover what has been lost. There are several rehabilitation approaches for spinal cord injuries, including conventional physical therapy, use of orthoses and orthostatism. Virtual Reality is a promising technology that has been used in the rehabilitation process, making it interesting and motivating for the patient. This article proposes to explain the importance of rehabilitation and its new possibilities, allied to virtual reality.

Sultanat Ihangiro, in Bananenpflanzungen, unter Blättern und Bananenstämmen. Bukoba auf Steinblöcken unter Laub. Unspecified number of ♂ and ♀.
 The MHNG collection contains 63 specimens in alcohol in two jars. The first jar (MHNG-ARTO-18562) contains parts of at least 17 specimens; five have pins running the length of the body and most are broken. One specimen has been separated in a vial along with a smaller vial containing gonopods. The identification labels in the jar have “ ♂ ♀ types Bukoba u. Ihangiro” and “ types Bukoba et Ihangiro Dr J. Carl” written on them respectively, indicating that the specimens are syntypes. The second jar (MHNG-ARTO-18563) contains parts of at least 46 specimens; two have a pin running the length of the body and many are badly broken. There is an original identification label with “Ihangiro” written on it, indicating that the specimens are syntypes. There are three syntypes in the ZMUH (Weidner, 1960), three in the ZMHB (Moritz & Fischer, 1978a) and three in the MCZL. The description and some of the old labels refer to “ S. fossiger var. typica ” but it could be argued that this indicates that the taxon is the nominal subspecies rather than being an available name.

description: La descentralización fiscal en República Dominicana es baja. Sólo el 2.79% del total del Sector Público No Financiero es devengado por los gobiernos locales, lo que denota un bajo nivel de descentralización, ocupando uno de los lugares más bajos dentro de la región latinoamericana en lo que a proporción del gasto público descentralizado se refiere. Por otro lado, el gasto público local en inversión pública, muestra ser el único con una distribución a favor de las regiones con más necesidades, mientras que el resto del gasto local está distribuido para favorecer a las comunidades más desarrolladas. En términos de equidad, ninguna de los destinos de gasto responde a criterios de equidad vertical u horizontal. Al analizar la descentralización de los ingresos fiscales, sólo el 23.48% del total de los ingresos de los gobiernos locales no provienen de transferencias desde el Gobierno Central, lo que denota la baja descentralización recaudatoria.
Dynamics and Quantum correlations in Two independently driven Rydberg atoms with distinct laser fields

description: We study the population dynamics in a two-atom setup in which each atom is driven independently by different light fields, but coupling the same Rydberg state. In particular, we look at how an offset in the Rabi frequencies between two atoms influences the dynamics. We find novel features such as amplifying the Rabi frequency of one atom, together with strong Rydberg-Rydberg interactions freezes the dynamics in the second atom. We characterize the Rydberg-biased freezing phenomenon in detail, with effective Hamiltonians obtained for various limits of the system parameters. In the absence of Rabi-offset, the doubly excited state population exhibits a Lorentzian profile as a function of interaction, whereas for very small offsets it shows splitting and thus peaks. Using an effective Hamiltonian as well as the perturbation theory for weak interactions, we show that the peak arises from a competition between Rabi-offset and Rydberg-Rydberg interactions when both are sufficiently small, together with the Rydberg blockade at large interactions. The effective Hamiltonians provide us with analytical results which are in an excellent agreement with full numerical solutions. Also, we analyze the growth and the dynamics of quantum correlations such as entanglement entropy and quantum discord for the coherent dynamics. We extend our studies to the dissipative case in which the spontaneous emission from the Rydberg state is taken into account and in particular, we look at the purity and quantum discord of the steady states. To conclude, our studies reveal that the local manipulation of an atom using Rabi-offset can be an ideal tool to control the quantum correlations and in general, quantum states of the composite two-qubit systems.
