description: Negative stimuli do not only evoke fear or disgust, but can also evoke a state of ‘morbid fascination’ which is an urge to approach and explore a negative stimulus. In the present neuroimaging study, we applied an innovative method to investigate the neural systems involved in typical and atypical conceptualizations of negative images. Participants received false feedback labeling their mental experience as fear, disgust or morbid fascination. This manipulation was successful; participants judged the false feedback correct for 70% of the trials on average. The neuroimaging results demonstrated differential activity within regions in the ‘neural reference space for discrete emotion’ depending on the type of feedback. We found robust differences in the ventrolateral prefrontal cortex, the dorsomedial prefrontal cortex and the lateral orbitofrontal cortex comparing morbid fascination to control feedback. More subtle differences in the dorsomedial prefrontal cortex and the lateral orbitofrontal cortex were also found between morbid fascination feedback and the other emotion feedback conditions. This study is the first to forward evidence about the neural representation of the experimentally unexplored state of morbid fascination. In line with a constructionist framework, our findings suggest that neural resources associated with the process of conceptualization contribute to the neural representation of this state.

description: Cephalothrix lacustris Malone et al. (2015: 3004) (Figs 2D, 2I, 2J)
 Strains:— LEGE 15487 (MF629804), LEGE 15492 (MF629809) and LEGE 15493 (MF629810).
 Description:— In culture, the trichomes start growing at the bottom of the culture flask, forming a thin biofilm towards the top, at the air-medium interface. Groups of filaments may float on the surface of the culture medium or may stay attached to air bubbles at the bottom of the flask. Trichomes are straight or flexuous, slightly constricted at the cell-cell joints and exhibit gliding motility and biconcave necridia. The trichomes are pale to olive-green and are solitary or grouped in mats. In addition, the trichomes have facultative hyaline and firm sheaths that are either attached to the trichome or are at a slight distance (Fig. 2D, 2I, 2J). Cells are wider (4.2–7.5 μm) than long (1.4–3.8 μm) and have facultative gas vesicles. Apical cells might be rounded or capitate and have facultative calyptra.
 Phylogeny and polyphasic identification:— The 16S rRNA gene sequences of LEGE 15487, LEGE 15493 and LEGE 15492 showed similarity values equal or higher than 98.8% (Table 4) with the sequences from Cephalothrix lacustris Malone et al. (2015: 3004) CCIBt 3261 (98.8–99.5%) and C. lacustris CMAA 1561 (98.9–99.5%). Concerning the phylogenetic tree, only the ML method was able to give support to a subgroup formed by the abovementioned strains plus C. komarekiana Malone et al. (2015: 3003) CMAA 1558 and Phormidium sp. KS (Fig. 3, see also Fig. S1 and Fig. S2). Still, the three inference methods support a major clade (ML/BI/MP = 100/1.00/97) that encloses the abovementioned group of sequences and also the sequence of Cephalothrix komarekiana CCIBt 3277, the type strain of the genus (Fig. 3). Based on the morphology, ecology and molecular data, these LEGE strains can be identified as Cephalothrix lacustris.

description: Light scalars (as the axion) with mass m ~ 10^{-22} eV forming a Bose-Einstein condensate (BEC) exhibit a Jeans length in the kpc scale and were therefore proposed as dark matter (DM) candidates. Our treatment here is generic, independent of the particle physics model and applies to all DM BEC, in or out of equilibrium. Two observed quantities crucially constrain DM in an inescapable way: the average DM density rho_{DM} and the phase-space density Q. The observed values of rho_{DM} and Q in galaxies today constrain both the possibility to form a BEC and the DM mass m. These two constraints robustly exclude axion DM that decouples just after the QCD phase transition. Moreover, the value m ~ 10^{-22} eV can only be obtained with a number of ultrarelativistic degrees of freedom at decoupling in the trillions which is impossible for decoupling in the radiation dominated era. In addition, we find for the axion vacuum misalignment scenario that axions are produced strongly out of thermal equilibrium and that the axion mass in such scenario turns to be 17 orders of magnitude too large to reproduce the observed galactic structures. Moreover, we also consider inhomogenous gravitationally bounded BEC's supported by the bosonic quantum pressure independently of any particular particle physics scenario. For a typical size R ~ kpc and compact object masses M ~ 10^7 Msun they remarkably lead to the same particle mass m ~ 10^{-22} eV as the BEC free-streaming length. However, the phase-space density for the gravitationally bounded BEC's turns to be more than sixty orders of magnitude smaller than the galaxy observed values. We conclude that the BEC's and the axion cannot be the DM particle. However, an axion in the mili-eV scale may be a relevant source of dark energy through the zero point cosmological quantum fluctuations.

description: The saddle point approximation of the path integral partition functions is an important way of deriving the thermodynamical properties of black holes. However, there are certain black hole models and some mathematically analog mechanical models for which this method cannot be applied directly. This is due to the fact that their action evaluated on a classical solution is not finite and its first variation does not vanish for all consistent boundary conditions. These problems can be dealt with by adding a counterterm to the classical action, which is a solution of the corresponding Hamilton-Jacobi equation. In this work we study the effects of polymer quantization on a mechanical model presenting the aforementioned difficulties and contrast it with the above counterterm method. This type of quantization for mechanical models is motivated by the loop quantization of gravity which is known to play a role in the thermodynamics of black hole systems. The model we consider is a nonrelativistic particle in an inverse square potential, and analyze two polarizations of the polymer quantization in which either the position or the momentum is discrete. In the former case, Thiemann's regularization is applied to represent the inverse power potential but we still need to incorporate the Hamilton-Jacobi counterterm which is now modified by polymer corrections. In the latter, momentum discrete case however, such regularization could not be implemented. Yet, remarkably, owing to the fact that the position is bounded, we do not need a Hamilton-Jacobi counterterm in order to have a well-defined saddle point approximation. Further developments and extensions are commented upon in the discussion.

description: Over the past years, network science has proven invaluable as a means to better understand many of the processes taking place in the brain. Recently, interareal connectivity data of the macaque cortex was made available with great richness of detail. We explore new aspects of this dataset, such as a correlation between connection weights and cortical hierarchy. We also look at the link-community structure that emerges from the data to uncover the major communication pathways in the network, and moreover investigate its reciprocal connections, showing that they share similar properties.

description: Recent behavioral and neuroimaging studies demonstrate that labeling one’s emotional experiences and perceptions alters those states. Here, we used a comprehensive meta-analysis of the neuroimaging literature to systematically explore whether the presence of emotion words in experimental tasks has an impact on the neural representation of emotional experiences and perceptions across studies. Using a database of 386 studies, we assessed brain activity when emotion words (e.g. ‘anger’, ‘disgust’) and more general affect words (e.g. ‘pleasant’, ‘unpleasant’) were present in experimental tasks vs not present. As predicted, when emotion words were present, we observed more frequent activations in regions related to semantic processing. When emotion words were not present, we observed more frequent activations in the amygdala and parahippocampal gyrus, bilaterally. The presence of affect words did not have the same effect on the neural representation of emotional experiences and perceptions, suggesting that our observed effects are specific to emotion words. These findings are consistent with the psychological constructionist prediction that in the absence of accessible emotion concepts, the meaning of affective experiences and perceptions are ambiguous. Findings are also consistent with the regulatory role of ‘affect labeling’. Implications of the role of language in emotion construction and regulation are discussed.

description: Quantum Markov models are employed ubiquitously in quantum physics and in quantum information theory due to their relative simplicity and analytical tractability. In particular, these models are known to give accurate approximations for a wide range of quantum optical and mesoscopic systems. However, in general, the validity of the Markov approximation entails assumptions regarding properties of the system of interest and its environment, which may not be satisfied or accurate in arbitrary physical systems. Therefore, developing useful modelling tools for general non-Markovian quantum systems for which the Markov approximation is inappropriate or deficient is an undertaking of significant importance. This work considers non-Markovian principal quantum systems that can be embedded in a larger Markovian quantum system with one or more compound baths consisting of an auxiliary quantum system and a quantum white noise field, and derives a set of coupled stochastic and quantum master equations for embedded non-Markovian quantum systems. The case of a purely Hamiltonian coupling between the principal and auxiliary systems as a closed system without coupling to white noises is included as a special case. The results are expected to be of interest for (open-loop and feedback) control of continuous-time non-Markovian systems and studying reduced models for numerical simulation of such systems. They may also shed more light on the general structure of continuous-time non-Markovian quantum systems.

description: Investigating the CKM matrix in different parametrization schemes, it is noticed that those schemes can be divided into a few groups where the sine values of the CP phase for each group are approximately equal. Using those relations, several approximate equalities among the elements of CKM matrix are established. Assuming them to be exact, there are infinite numbers of solutions and by choosing special values for the free parameters in those solutions, several textures presented in literature are obtained. The case can also be generalized to the PMNS matrix for the lepton sector. In parallel, several mixing textures are also derived by using presumed symmetries, amazingly, some of their forms are the same as what we obtained, but not all. It hints existence of a hidden symmetry which is broken in the practical world. The nature makes its own selection on the underlying symmetry and the way to break it, while we just guess what it is.

That is, its Waring decomposition as a sum of r powers of linear forms is unique. Only three exceptional cases arise, all of which were known in the literature. Our original contribution regards the case of cubics ($d=3$), while for $d\ge 4$ we rely on known results on weak defectivity by Ballico, Ciliberto, Chiantini, and Mella.

description: We study the quantization of two versions of unimodular gravity, namely, fully diffeomorphism-invariant unimodular gravity and unimodular gravity with fixed metric determinant utilizing standard path integral approach. We derive the BRST symmetry of effective actions corresponding to several relevant gauge conditions. We observe that for some gauge conditions, the restricted gauge structure may complicate the formulation and effective actions, in particular, if the chosen gauge conditions involve the canonical momentum conjugate to the induced metric on the spatial hypersurface. The BRST symmetry is extended further to the finite field-dependent BRST transformation, in order to establish the mapping between different gauge conditions in each of the two versions of unimodular gravity.

description: This article presents a novel solution for reconfigurable intelligent surfaces (RISs) based on cascaded channel decoupling. The proposed mechanism simplifies the RIS regulation matrix, by decomposing the electromagnetic wave regulation process into two sub-processes: virtual receiving response and virtual regular transmission, which leads to the decoupling of the RIS cascaded channel. This article further discusses the concrete implementation of the proposed channel decoupling mechanism in two scenarios of single-user access and multi-user access, and gives the corresponding detailed scheme. The numerical simulation results demonstrate that the proposed channel decoupling scheme is a low-complexity and effective solution for resolving the RIS regulation matrix.

description: We prove a conjecture stated by Catalisano, Geramita, and Gimigliano in 2002, which claims that the secant varieties of tangential varieties to the $d$th Veronese embedding of the projective $n$-space $\mathbb{P}^n$ have the expected dimension, modulo a few well-known exceptions. As Bernardi, Catalisano, Gimigliano, and Idá demonstrated that the proof of this conjecture may be reduced to the case of cubics, i.e., $d=3$, the main contribution of this work is the resolution of this base case. The proposed proof proceeds by induction on the dimension $n$ of the projective space via a specialization argument. This reduces the proof to a large number of initial cases for the induction, which were settled using a computer-assisted proof. The individual base cases were computationally challenging problems. Indeed, the largest base case required us to deal with the tangential variety to the third Veronese embedding of $\mathbb{P}^{79}$ in $\mathbb{P}^{88559}$.

 Strains:— LEGE 15488 (MF629805)
 Description:— In culture, dark-green groups of filaments grow in fascicles all over the flask walls and at the interface between the air and the culture medium. The strain produces air bubbles that are visible at the bottoms of culture flasks. Trichomes are long, olive-green to dark-green. The trichomes are isopolar, straight to curved or even coiled, immotile, non-constricted or slightly constricted at the cross-walls, non-attenuated at their ends, and have necridia and facultative sheaths (Fig. 2E). The cells are wider (5.6–8.8 μm) than long (1.7–3.8 μm) and have granules.
 Phylogeny and polyphasic identification:— The 16S rRNA gene sequence of LEGE 15488 shares 98% identity with the sequences of three strains identified as Phormidium, Lyngbya Agardh ex Gomont (1892: 118) and with an unidentified cyanobacterium (Table S1). The sequence of LEGE 15488 (Table 4) shows higher similarity values with the sequences from the strains Phormidium sp. LEGE 05292 (98.2%) and Lyngbya JW-2010b (98.1%), and to a less degree with that of Phormidium irriguum (Kützing ex Gomont) Anagnostidis & Komárek (1988: 405) CCALA 759 (96.9%). As shown in Fig. 3, LEGE 15488 is placed in a robust clade (ML/BI/MP = 100/1.00/100) with the strain P. irriguum CCALA 759, at the base of the clade, which is an isolate that was proposed as epitype for this species and also for the genus (Sciuto et al. 2012). Based on the polyphasic evaluation of LEGE 15488, this strain was identified as Phormidium sp. (Komárek & Anagnostidis, 2005, Sciuto et al. 2012).

D4.6: Analysis of User Requirements, Needs and Visionary User Cases for ARETE – UPDATE
Creators: name: ARETE
Publisher: name: Zenodo
Year: 2022

description: User requirements evolve in the process of software development. In the early phase of the ARETE project, we captured requirements from the ARETE target groups with the three surveys targeting primary school students, secondary school students, and teachers. Analysis results were distilled into different sets of requirements; many of which need to be addressed at the institutional (e.g., school governance) and governmental (e.g., educational authorities) levels, for instance, provision of quality digital devices to run AR applications (for details see D4.2 M18). These requirements entail long-term strategic changes and thus may only be addressed beyond the lifetime of the ARETE project, which is aimed to provide policymakers with empirical evidence for the efficacy of AR as educational tool. Regarding the technical requirements, functional as well as non-functional, for deploying AR educational applications, collaborative efforts between WP4 and other WPs (WP3, WP5 and WP6), have been invested to ensure the high interaction quality of the ARETE Pilot apps. Details of the related research activities and results can be found in D4.5 (M30). This deliverable reports on two major tasks undertaken recently by WP4: (i) our new initiative to expand the ARETE work to South America (Section 2) and (ii) the evaluation of three PBIS multi-user apps (Section 3).

description: We present a detailed study of the annihilation signals of the inert dark matter doublet model in its high mass regime. Concretely, we study the prospects to observe gamma-ray signals of the model in current and projected Cherenkov telescopes taking into account the Sommerfeld effect and including the contribution to the spectrum from gamma-ray lines as well as from internal bremsstrahlung. We show that present observations of the galactic center by the H.E.S.S. instrument are able to exclude regions of the parameter space that give the correct dark matter relic abundance. In particular, models with the charged and the neutral components of the inert doublet nearly degenerate in mass have strong gamma-ray signals. Furthermore, for dark matter particle masses above 1 TeV, we find that the non-observation of the continuum of photons generated by the hadronization of the annihilation products typically gives stronger constraints on the model parameters than the sharp spectral features associated to annihilation into monochromatic photons and the internal bremsstrahlung process. Lastly, we also analyze the interplay between indirect and direct detection searches for this model, concluding that the prospects for the former are more promising. In particular, we find that the upcoming Cherenkov Telescope Array will be able to probe a significant part of the high mass regime of the model.

description: The tensor rank decomposition problem consists of recovering the unique set of parameters representing a robustly identifiable low-rank tensor when the coordinate representation of the tensor is presented as input. A condition number for this problem measuring the sensitivity of the parameters to an infinitesimal change to the tensor is introduced and analyzed. It is demonstrated that the absolute condition number coincides with the inverse of the least singular value of Terracini's matrix. Several basic properties of this condition number are investigated.

description: The MacWilliams Extension Theorem states that each linear isometry of a linear code extends to a monomial map. Unlike the linear codes, in general, additive codes do not have the extension property. In this paper, an analogue of the extension theorem for additive codes in the case of additive MDS codes is proved. More precisely, it is shown that for almost all additive MDS codes their additive isometries extend to isometries of the ambient space.

description: The current study aimed to capture empathy processing in an interpersonal context. Mother–adolescent dyads (N = 22) each completed an empathy task during fMRI, in which they imagined the target person in distressing scenes as either themselves or their family (i.e. child for the mother, mother for the child). Using multi-voxel pattern approach, we compared neural pattern similarity for the self and family conditions and found that mothers showed greater perceptual similarity between self and child in the fusiform face area (FFA), representing high self–child overlap, whereas adolescents showed significantly less self–mother overlap. Adolescents’ pattern similarity was dependent upon family relationship quality, such that they showed greater self–mother overlap with higher relationship quality, whereas mothers’ pattern similarity was independent of relationship quality. Furthermore, adolescents’ perceptual similarity in the FFA was associated with increased social brain activation (e.g. temporal parietal junction). Mediation analyses indicated that high relationship quality was associated with greater social brain activation, which was mediated by greater self–mother overlap in the FFA. Our findings suggest that adolescents show more distinct neural patterns in perceiving their own vs their mother’s distress, and such distinction is sensitive to mother–child relationship quality. In contrast, mothers’ perception for their own and child’s distress is highly similar and unconditional.

description: A graph $G$ is minimally $t$-tough if the toughness of $G$ is $t$ and the deletion of any edge from $G$ decreases the toughness. Kriesell conjectured that for every minimally $1$-tough graph the minimum degree $δ(G)=2$. We show that in every minimally $1$-tough graph $δ(G)\le\frac{n+2}{3}$. We also prove that every minimally $1$-tough claw-free graph is a cycle. On the other hand, we show that for every $t \in \mathbb{Q}$ any graph can be embedded as an induced subgraph into a minimally $t$-tough graph.

description: We investigate scalar field theories in de Sitter space by means of nonperturbative renormalization group techniques. We compute the functional flow equation for the effective potential of O(N) theories in the local potential approximation and we study the onset of curvature-induced effects as quantum fluctuations are progressively integrated out from subhorizon to superhorizon scales. This results in a dimensional reduction of the original action to an effective zero-dimensional Euclidean theory. We show that the latter is equivalent both to the late-time equilibrium state of the stochastic approach of Starobinsky and Yokoyama and to the effective theory for the zero mode on Euclidean de Sitter space. We investigate the immediate consequences of this dimensional reduction: symmetry restoration and dynamical mass generation.

description: The poultry processing industry struggles to keep up with new developments in meat consumption and livestock breeding. Designing poultry processing systems is becoming increasingly more complex, and an increasing number of iterations of (re)design are required to optimize the product flow in these systems. To address this issue, this study presents a discrete-event simulation-based method for design space exploration of production systems. This method is mostly automated, greatly reducing the time and effort required in the design process. The steps that are automated are iterating on the design, model construction, performing simulation experiments, and interpreting the simulation results. An industrial case study in which a poultry processing system is redesigned is used to validate the effectiveness of the proposed method. A detailed description of this case study is given to showcase the different ways in which this design space exploration method can be used.

description: It is challenging to distinguish between fusion-fission and quasifission experimentally. To determine the characteristics of quasifission processes associated with dominant phenomena in heavy-ion collisions is important for estimating precisely the fusion cross section, which is relevant to the synthesis of new elements. We classified fusion-fission and quasifission processes theoretically in the past for an accurate assessment of the fusion cross section. However, no detailed analysis focused on each process was performed. In this work, we aimed to analyze the dynamical characteristics of quasifission processes in terms of the Langevin equation model. We specify the quasifission processes, and analyze the scission configuration. Finally, we clarify the origin of several modes included in quasifission. The calculation framework is the multidimensional dynamical model of nucleus-nucleus collisions based on the Langevin equations. It is shown that several quasifission modes exist leading to different fragment deformations. The time scale of the quasifission process differs for several different modes. Each scission configuration and total kinetic energy also differ. The different quasifission modes are caused by the neck relaxation controlling the mass drift toward symmetry. This means that it is possible to discuss the time-dependent functional form of the neck parameter $ε$ for the quasifission process in the framework of the dynamical model based on Langevin equations.

description: In applications where the tensor rank decomposition arises, one often relies on its identifiability properties for interpreting the individual rank-$1$ terms appearing in the decomposition. Several criteria for identifiability have been proposed in the literature, however few results exist on how frequently they are satisfied. We propose to call a criterion effective if it is satisfied on a dense, open subset of the smallest semi-algebraic set enclosing the set of rank-$r$ tensors. We analyze the effectiveness of Kruskal's criterion when it is combined with reshaping. It is proved that this criterion is effective for both real and complex tensors in its entire range of applicability, which is usually much smaller than the smallest typical rank. Our proof explains when reshaping-based algorithms for computing tensor rank decompositions may be expected to recover the decomposition. Specializing the analysis to symmetric tensors or forms reveals that the reshaped Kruskal criterion may even be effective up to the smallest typical rank for some third, fourth and sixth order symmetric tensors of small dimension as well as for binary forms of degree at least three. We extended this result to $4 \times 4 \times 4 \times 4$ symmetric tensors by analyzing the Hilbert function, resulting in a criterion for symmetric identifiability that is effective up to symmetric rank $8$, which is optimal.

description: CeTA was originally developed as a tool for certifying termination proofs which have to be provided as certificates in the CPF-format. Its soundness is proven as part of IsaFoR, the Isabelle Formalization of Rewriting. By now, CeTA can also be used for certifying confluence and non-confluence proofs. In this system description, we give a short overview on what kind of proofs are supported, and what information has to be given in the certificates. As we will see, only a small amount of information is required and so we hope that CSI will not stay the only confluence tool which can produce certificates.

description: This article aims to analyse the difficulties Central American refugee women face when applying for refugee protection in Mexico and how they negotiate survival during this process. Claiming refugee protection is an important legal mechanism to ensure survival, but managing this process successfully is difficult, not only because of the bureaucratic complexities but also because of structural and political constraints. Research has addressed the difficulties migrant women face while in transit and in the United States, but there is less analysis on the limitations in accessing refugee protection in transit countries such as Mexico. Therefore, this article examines the main barriers women face by considering the social and spatial specifics of two different reception sites, the southern Mexican city of Tapachula and Mexico City, in the centre of the country. Drawing on ethnographic field research and interviews with refugees and practitioners, this research seeks to understand women’s agency in dealing with adversity in reception contexts. Analysis showed that women need to engage in micro‐level negotiations with gatekeepers in host communities to gain access to humanitarian assistance and social rights. In addition, it has showed that access to scarce resources depends on personal performance in terms of vulnerability and “deservingness.” This demonstrates the complexities refugee women encounter in the local context, but also the role of institutional constraints to humanitarian attention in contrast to an integral understanding of rights. Furthermore, the obstacles faced by refugees and the generation of uncertainty and waiting must be analysed as a political strategy to prevent effective access to asylum in Mexico.

description: The importance of childhood circumstances, broadly defined, for shaping adult health and longevity is well-established. But the significance of one of the most prevalent childhood adversities—exposure to problem drinkers—has been understudied from a sociological perspective and remains poorly understood. We address this gap by drawing on cumulative inequality theory, using data from the 1988–2011 National Health Interview Survey-Linked Mortality Files, and estimating Cox proportional hazards models to examine the relationship between exposure to problem drinkers in childhood and adult mortality risk. Childhood exposure to problem drinkers is common (nearly 1 in 5 individuals were exposed) and elevates adult overall and cause-specific mortality risk. Compared to individuals who had not lived with a problem drinker during childhood, those who had done so suffered 17 percent higher risk of death (p<.001) over the follow-up period, net of age, sex, and race/ethnicity. We find compelling evidence that the duration, source, and intensity of exposure to problem drinkers in childhood contributes to inequality in adult mortality risk. Favorable socioeconomic status in adulthood does not ameliorate the consequences of childhood exposure to problem drinkers. The primary intervening mechanisms are risky behaviors, including adult drinking and smoking. The findings—which reveal that the influence of problem drinking is far-reaching and long-term—should inform policies to improve childhood circumstances, reduce detrimental effects of problem drinking, and increase life expectancy.

description: The rapid proliferation of computing domains relying on Internet of Things (IoT) devices has created a pressing need for efficient and accurate deep-learning (DL) models that can run on low-power devices. However, traditional DL models tend to be too complex and computationally intensive for typical IoT end-nodes. To address this challenge, Neural Architecture Search (NAS) has emerged as a popular design automation technique for co-optimizing the accuracy and complexity of deep neural networks. Nevertheless, existing NAS techniques require many iterations to produce a network that adheres to specific hardware constraints, such as the maximum memory available on the hardware or the maximum latency allowed by the target application. In this work, we propose a novel approach to incorporate multiple constraints into so-called Differentiable NAS optimization methods, which allows the generation, in a single shot, of a model that respects user-defined constraints on both memory and latency in a time comparable to a single standard training. The proposed approach is evaluated on five IoT-relevant benchmarks, including the MLPerf Tiny suite and Tiny ImageNet, demonstrating that, with a single search, it is possible to reduce memory and latency by 87.4% and 54.2%, respectively (as defined by our targets), while ensuring non-inferior accuracy on state-of-the-art hand-tuned deep neural networks for TinyML.

Agent-based modelling of air transport demand

description: Constraints such as opening hours or passenger capacities influence travel options that can be offered by an airport and by the connecting airlines. If infrastructure, policy or technological measures modify transport options, then the benefits do not only depend on the technology, but also on possibly heterogeneous user preferences such as desired arrival times or on the availability of alternative travel modes. This paper proposes an agent-based, iterative assignment procedure to model European air traffic and German passenger demand on a microscopic level, capturing individual passenger preferences. Air transport technology is simulated microscopically, i.e. each aircraft is represented as single unit with attached attributes such as departure time, flight duration or seat availability. Trip-chaining and delay propagation can be added. Microsimulation is used to verify and assess passengers’ choices of travel alternatives, where those choices improve over iterations until an agent-based stochastic user equilibrium is reached. This requires fast simulation models, thus, similar to other approaches in air traffic modelling a queue model is used. In contrast to those approaches, the queue model in this work is solved algorithmically. Overall, the approach is suited to analyze, forecast and evaluate the consequences of mid-distance transport measures.
