Higher-Order Networks in Complex Systems: Temporality and Interconnectivity

A particular approach to study complex systems in nature, society and technology is network theory. In this perspective actors in the system are represented as nodes and interactions or connections among the actors as links. Although the usual framework is often sufficient to study complex systems, it neglects additional properties that are not easily captured. The focus of this thesis is the expansion of classical approaches in network theory that allow to overcome some of the limitations imposed by oversimplifications. We provide higher-order models that take into account additional information of complex systems, in particular the aspects of temporality and interconnectivity. In the first part we study temporal networks in which the interactions or connections that occur in the systems are tagged with a time-stamp. This allows to study different aspect of temporal interaction sequences, such as the duration of interactions or inter-event times. In this work we focus on the ordering of links, rather than the timing. To study temporal ordering we develop a framework of higher-order time-aggregated networks, a generalization of the commonly applied static, time-aggregated representation of temporal networks. This approach explicitly captures temporal path statistics and therefore is able to preserves causality structures. With this tool at hand we discuss and analyze different application scenarios that reveal the need of higher-order models and that highlight the power of the proposed approach. More precisely, we study path-based centralities and dynamical processes in respect of temporal ordering. In the second part we investigate coupled systems that are interconnected, meaning that a system is not only influenced by the connections among its own nodes but also by connections to other systems. Recent research has addressed this issue with so-called multi-layer networks. First, we investigate the lack information one is often confronted with when analyzing real-world systems. The detailed multi-layer topology can be missing and only aggregated statistics may be available. We study dynamical processes in different cases where we rely on limited information of the link topology. Next, we focus on a system of scholarly publications that combines different types of links and nodes that are connected to each other. Leveraging on the multi-layer topology we investigate how co-authorships are correlated with citations and how this affects citation based ranking schemes. Concluding, this thesis provides a deeper understanding of complex systems and goes beyond the commonly used static and decoupled network approach. We not only show the need of an extended perspective but also provide models that overcome the aforementioned limitations. Validating our models on empirical data sets we contribute new insights and techniques that can be used in a broad variety of applications.
Universality Patterns in the Training of Neural Networks

This paper proposes and demonstrates a surprising pattern in the training of neural networks: there is a one to one relation between the values of any pair of losses (such as cross entropy, mean squared error, 0/1 error etc.) evaluated for a model arising at (any point of) a training run. This pattern is universal in the sense that this one to one relationship is identical across architectures (such as VGG, Resnet, Densenet etc.), algorithms (SGD and SGD with momentum) and training loss functions (cross entropy and mean squared error).

Adaptive Optics for Extremely Large Telescopes III CHARACTERIZATION OF THE MAIN COMPONENTS OF THE GTCAO SYSTEM : 373 ACTUATORS DM AND OCam 2 CAMERA

Adaptive optics systems rely on wavefront correctors and wavefront sensors as main components. At GTC, we are integrating the adaptive optics system, which is a classic, single conjugate. However, it will employ a 373 actuators (21x21) DM from CILAS and the camera employed at the wavefront sensor will be OCam2, a state of the art camera based on L3CCD technology. OCam2 is one of the most perfomant cameras for Adaptive Optics offering at the same time very low readout noise (subelectron noise) and very high frame rate (>1Kfps). Both components have been extensively tested at our premises, and the results are presented here. A better knowledge of these components allows having a more efficient adaptive optics system. The DM is characterized by means of interferometric measurements to assess its main parameters, as inter-actuator stroke, full mechanical actuator stroke, homogeneity of the influence function, hysteresis.
Querying Semantically Enriched Sensor Observations : Short Paper

The increase that sensor network deployments are experiencing makes them one of the fastest growing sources of data nowadays. They allow live and in-situ data capture and provide high volumes of information about the real world that surrounds us. However their heterogeneity and error-proneness make them hard to use, as we normally require lots of details of each one before their measurements can be combined. We present an ontology-based approach for querying live sensor observations, enriched with semantic metadata. The metadata is used in two scenarios: (i) for adding contextual information to the sensor observations, such as which sensor recorded what, where, when, and in which conditions; and (ii) to help users filter sensor data in their queries. We provide automatic query translation and join of sensor data and metadata, using mappings of the underlying sensor schemas to semantically annotate sensor observations. With this approach we can express queries in terms of a high level sensor network ontology, using an extension of the SPARQL query language that considers window constructs.

Multi-Sketch Alignment in the Context of Volunteered Geographic Information

Sketch maps are an intuitive way of expressing geospatial information. They contain objects which represent real world geographic features, relations between these objects, and oftentimes symbolic and textual annotations (Blaser, 1998). These elements enable us to use sketch maps to communicate about our environments and to reason about our actions in those environments. In this way sketch maps provide an intuitive user interaction modality for some geospatial computer applications (Egenhofer, 1998). Especially with the advent of Volunteered Geographic Information (VGI) (Goodchild, 2007) sketch maps may be the key to removing the barriers imposed by the technical requirements of traditional Geographic Information Systems (GIS) (Schwering, 2010). In order to allow users to contribute and query geographic information using sketch maps an automated system must be able to analyze them and ground them in the real world (Wallgrün, 2010). Some sketch based geospatial query systems achieve this by extracting the spatial relations between objects in the sketch map and searching the database for a set of objects that share matching or similar relations. Two examples of this approach are Spatial-Query-By-Sketch (SQBS) (Egenhofer, 1998) and Qualitative Matching (Wallgrün, 2010) which I will refer to as QM in this paper.
Exemplar-based Underwater Image Enhancement Augmented by Wavelet Corrected Transforms

In this paper we propose a novel deep learning framework to enhance underwater images by augmenting our network with wavelet corrected transformations. Wavelet transforms have recently made way into deep learning frameworks and their ability to reconstruct arbitrary signals accurately makes them favorable for many applications. Underwater images are subjected to unique distortions, this is mainly attributed to the fact that red wavelength light gets absorbed dominantly giving a greenish, blue hue. This wavelength dependent selective absorption of light and also scattering by the suspended particles introduce non-linear distortions that affect the quality of the images. We propose an encoder-decoder module with wavelet pooling and unpooling as one of the network components to perform progressive whitening and coloring transforms to enhance underwater images via realistic style transfer. We give a sound theoretical proof as to why wavelet transforms are better for signal reconstruction. We demonstrate our proposed framework on popular underwater images dataset and evaluate it using metrics like SSIM, PSNR and UCIQE and show that we achieve state-of-the-art results compared to those mentioned in the literature.

The End of Logic Locking? A Critical View on the Security of Logic Locking

With continuously shrinking feature sizes of integrated circuits, the vast majority of semiconductor companies have become fabless, i.e., chip manufacturing has been outsourced to foundries across the globe. However, by outsourcing critical stages of IC fabrication, the design house puts trust in entities which may have malicious intents. This exposes the design industry to a number of threats, including piracy via unauthorized overproduction and subsequent reselling on the black market. One alleged solution for this problem is logic locking, also known as logic encryption, where the genuine functionality of a chip is “locked” using a key only known to the designer. If a correct key is provided, the design works as intended but with an incorrect key, the circuit produces faulty outputs. As the keys are inserted by the designer after production, an adversarial foundry should not be able to unlock overproduced chips. In this work, we highlight major shortcomings of proposed logic locking schemes. They are primarily due to the absence of a well-defined and realistic attacker model in the current literature. To this end, we characterize physical capabilities of a malicious foundry, especially with respect to invasive attacks. This allows us to derive an attacker model that matches reality, yielding attacks against the foundations of locking schemes beyond the usually employed SAT-based attacks. Our analysis shows that no previously proposed logic locking scheme is able to achieve the intended protection goals against piracy in real-world scenarios. As an important conclusion, we argue that there are strong indications that logic locking will most likely never be secure against a determined malicious foundry.

PHYLOGENETIC ANALYSIS OF THAI OYSTER ( OSTREIDAE ) BASED ON PARTIAL SEQUENCES OF THE MITOCHONDRIAL 165 TDNA GENE

Ten oyster species of the family Ostreidae (Subfamilies Crassostreinae and Lophinae) from Thailand were studied using morphologic al data and mitochondrial 165 rDNA gene sequences. Additional sequence data from five specimens of Ostreidae and one specimen of Tridacna g4gas were downloaded from GenBank (7. gigas was used as outgroup). Some specimens were found to be genetically identical despite obvious morphological differences (e.g. four specimens of Crassostrea iredalei from east and west sides of the Malaysian peninsula and Saccostrea forskali and S. cf. malqbonensis, both from Thai waters). The results indicate that Striostrea mytiloides belongs to the genus ,Saccostrea. The results also suggest that none of the three subfamilies in Ostreidae is monophvletic.
Title : Multi-Dimensional Hybrid Design and Construction of Skyscraper Cluster

Designed by star architect of Moshes Safdie, Raffles City Chongqing includes a total of 6 mega high-rise towers 250 to 380 m tall, a sky conservatory, a 5-storey high shopping mall and a 3-storey basement car parking. Located at the confluence of the Yangtze and Jailing Rivers, the site for the project is imbued with a significance that is immediately symbolic, both as a sign of Chongqing’s important past and as a vivid indicator of the city’s thriving present and future. The design for the project to be situated at this gateway takes as its governing idea the image of powerful sails upon the water. The outer facades of the project’s eight towers — the transparent surfaces that will face the water to the north — are meant to recall a fleet of ancient Chinese ships, with their huge rectangles of white canvas filled by the wind. This is a 1.13 million m mega scale integrated project of office, retail, hotel, service residence and high-end residence with the transportation hub and traffic circulation at various levels of the project. This paper presents the multi-dimensional hybrid design, engineering and construction of this mega scale project. The innovations and the cutting-edge technology used in this project are introduced and discussed benchmarking the design and construction of the skyscraper cluster in a major city like Chongqing of China.
How are Resentment and Prejudices Overcome to Establish Inter-Ethnic Neighborhood-Contact between Migrants and Natives ? ∗

Since Allport, social scientists emphasize the importance of personal contact for overcoming prejudices and enhancing social cohesion in mixed societies. At the same time, co-habitation rather seems to foster the opposite: the more ethnically diverse the neighborhood or city, the less people trust others and the more prejudiced they are against people of other ethnicities. But how do people get into contact with their inter-ethnic neighbors, if spatial proximity, as a first necessary condition, stirs prejudice and refusal to mix? The here proposed argument relies on assortative, relational and proximity mechanisms, as well as on interactions of these mechanisms. Using new data from a large-scale German survey, the impact of religious practices, frequency of inter-ethnic encounters at public places and public houses, and the regional average migrant host-country language skills are investigated. In addition, the results suggest that respondents with children can make more use of neighborhood opportunity structures to establish inter-ethnic contacts. Implications for general network theory, and the study of inter-ethnic contact in particular, are discussed
IMPACTS OF INDUSTRY 4.0 INVESTMENTS ON FIRM PERFORMANCE: EVIDENCE FROM ITALY

The adoption of industry 4.0 technologies is assumed to bring superior competitive advantage for adopting firms as drivers of efficiency, differentiation as well as support to innovation. However, no studies capture the impacts of industry 4.0 technologies on firm’s financial performance. The paper explores the relationship between investments in digital technologies and firm performances, by also examining which are the technologies more likely to be associated with superior performance and eventually the cumulative effect of technologies on performance. Based on unique data gathered in 2017 on a sample of 1,149 Italian firms, results show the positive impacts on adopters’ performance and the role of robotics and laser cutting in this relationship. No cumulative effect (i.e. adopting more than one or two technologies) is instead
JET NOISE REDUCTION USING PULSED FLUIDIC ACTUATION

ABSTRACT Steady and unsteady fluidic actuators, in the form of secondary control jets injecting from the nozzle lip, aimed at jet noise reduction, are investigated. Three different geometric configurations are tested: non-converging control jets, ‘open’ triangle convergence and ‘closed’ triangle convergence. By means of a triple decomposition of hot-wire data and a scaleseparation argument, the low-frequency perturbation (nearnozzle dynamics) and response (global, downstream dynamics) of the flow are studied. Comparison of the phase-averaged component of the decomposition with predictions of linear stability theory (LST) suggest that two qualitatively different responses are active: at the main forcing frequency the jet response looks to be non-linear; at two secondary, higher frequencies, LST gives reasonable predictions for the local growth rates and convection velocities.
11 The electrophysiology of the bilingual brain

In this chapter, we will focus on how bilinguals cope with reading individual words and sentences in their different languages, and on how electroencephalographic recordings could be used to explore the time course of the cognitive processes underlying bilingual comprehension of visually delivered linguistic stimuli. Event-related brain potentials comparing native and nonnative written language processing have been repeatedly used to reveal effects that occur very early in the stream of processing and that are essential for a correct understanding of the cognitive processes leading to efficient word and sentence processing by multilingual readers. We will summarize the most relevant studies from this field, and we will offer a list of recommendations for researchers aiming at using EEG as a tool to investigate the complex pattern of feed-forward and feedback interactive activations flowing along the visual recognition system that ultimately lead to efficient bilingual reading.

In a collaboration that involves the Meteorological Research Division (MRD), the Climate Research Division (CRD), and the Canadian Meteorological Centre (CMC), these systems are being prepared for operational implementation at CMC.
Abstract for “ Does Happiness Adapt to Poverty ? And , Poverty to Happiness ? ”

for “Does Happiness Adapt to Poverty? And, Poverty to Happiness? ” Sara Ayllón (Universitat de Girona, Spain) This paper studies to what extent poverty and psychological well-being can be thought of inputs in a feedback loop by which poverty may exert an influence on unhappiness and, at the same time, past low levels of general satisfaction with life may lead to economic hardship. This interrelationship is studied by means of an econometric strategy with feedback effects using data from the German Socio-Economic Panel (SOEP) for the period between 1992 and 2010. Results indicate that when accounting for high-order dynamics, past poverty experiences do not increase the probability of feeling unhappy which can be interpreted as a certain degree of psychological adaptation to poverty. On the other hand, unhappiness has a (short-lived) positive influence on the probability of being in poverty. Evidence suggests that psychological uneasiness can be added as an explanation to persistent poverty.
