Abstract:
Let τn be a random tree distributed as a Galton-Watson tree with geometric offspring distribution conditioned on {Zn = an} where Zn is the size of the nth generation and (an, n ∈ ℕ*) is a deterministic positive sequence. We study the local limit of these trees τn as n →∞ and observe three distinct regimes: if (an, n ∈ ℕ*) grows slowly, the limit consists in an infinite spine decorated with finite trees (which corresponds to the size-biased tree for critical or subcritical offspring distributions), in an intermediate regime, the limiting tree is composed of an infinite skeleton (that does not satisfy the branching property) still decorated with finite trees and, if the sequence (an, n ∈ ℕ*) increases rapidly, a condensation phenomenon appears and the root of the limiting tree has an infinite number of offspring.

Abstract:
As a generalization of Rota–Baxter algebras, the concept of an Ω-Rota–Baxter could also be regarded as an algebraic abstraction of the integral analysis. In this paper, we introduce the concept of an Ω-dendriform algebra and show the relationship between Ω-Rota–Baxter algebras and Ω-dendriform algebras. Then, we provide a multiplication recursion definition of typed, angularly decorated rooted trees. Finally, we construct the free Ω-Rota–Baxter algebra by typed, angularly decorated rooted trees.

Abstract:
In the rites of seeing off the conscripts in the Kostroma and Vologda regions the Ural Federal University Toponymic expedition recorded the custom of decorating a tree at the exit from the village or hanging such a decorated tree on the pediment of a recruit’s house, and the custom of breaking or wrapping the trees tops on the edge of the village (this was done also to mark some other significant events in human life). The article shows that these customs have different origins, they were included from different sources into the recruit’s leaving rite during its formation in the 18th–19th centuries. The custom of decorating trees is a direct borrowing from the wedding ceremony and comes from the common Slavic tradition to decorate a wedding tree, symbolizing “girlish beauty”. The custom of breaking a tree top has a substratum origin and probably goes back to the tradition of the Kostroma Meria, which is reconstructed on the basis of Uralo-Yukaghir concepts about a person’s connection with a tree and the ancient custom of marking important events in human life (rites de passages) by making a personal tree by breaking off branches on coniferous trees preserved by Karelians (karsikko), Udmurts and Yukaghirs, which penetrated into North America in ancient times and was found among the Karok Indians in Northern California.

Abstract:
Attack–defense trees can be used as part of threat and risk analysis for system development and maintenance. They are an extension of attack trees with defense measures. Moreover, tree nodes can be decorated with attributes, such as probability, impact, and penalty, to increase the expressiveness of the model. Attribute values are typically assigned based on cognitive estimations and historically recorded events. This paper presents a practical case study with attack–defense trees. First, the authors create an attack–defense tree for an RFID-based goods management system for a warehouse. Then, they explore how to use a rich set of attributes for attack and defense nodes and assign and aggregate values to obtain condensed information, such as performance indicators or other key security figures. The authors discuss different modeling choices and tradeoffs. The case study led them to define concrete guidelines that can be used by software developers, security analysts, and system owners when performing similar assessments.

Abstract:
Abstract This article discusses two near-complete ceramic vessels—a deep, cup-shaped bowl and a shallow bowl/plate—found in recent excavations carried out at the rural site of el-Khirba/Nes Ziyyona in central Israel, in an early Abbasid context dated to the ninth century. The vessels bear unusual painted decorations on their exterior and interior. The decoration of the first bowl consists of alternating pairs of large black and white palm trees and large birds. The second bowl/plate is decorated with eight stylized trees emerging from a central circle, with small circles between them; these motifs were drawn in black over a white-painted surface. These bowls are associated with a local fine ware ceramic group, known as Fine Byzantine (or Fine Islamic) Ware, which originated in the Jerusalem region. However, their decorations reflect stylistic traditions familiar across the Early Islamic Near East and beyond, including from statuary works, illustrated manuscripts, and other ceramics. Altogether, it can be suggested that rural elites in Early Islamic Palestine used luxury ceramics decorated with pan-Islamic patterns as a way of identifying themselves with cosmopolitan, pan-Islamic society.

Abstract:
AbstractA combinator-based parser is a parser constructed directly from a BNF grammar, using higher-order functions (combinators) to model the alternative and sequencing operations of BNF. This paper describes a method for constructing parser combinators that can be used to build efficient predictive parsers which accurately report the cause of parsing errors. The method uses parsers that return values (parse trees or error indications) decorated with one of four tags.

Abstract:
We give a new combinatorial interpretation of the stationary distribution of the (partially) asymmetric exclusion process on a finite number of sites in terms of decorated alternative trees and coloured permutations. The corresponding expressions of the multivariate partition functions are then related to multivariate generalisations of Eulerian polynomials for coloured permutations considered recently by N. Williams and the third author, and others. We also discuss stability and negative dependence properties satisfied by the partition functions.

Abstract:
Le travail présenté dans cette thèse relève du domaine de l'analyse numérique et s'appuie sur des outils issus de l'étude des équations aux dérivées partielles (EDP). Nous nous concentrons sur les discrétisations temporelles des équations dispersives non linéaires. L'objectif est de réduire les hypothèses de régularité nécessaires lors de la conception et de l'analyse des méthodes numériques, afin de traiter les dynamiques à faible régularité.La partie I de la thèse introduit de nouveaux schémas à faible régularité, adaptés à des domaines bornés génériques. Le chapitre 2 présente des résultats de convergence au premier et au second ordre pour l'approximation de l'équation de Gross-Pitaevskii, lorsque la donnée initiale et le potentiel sont peu réguliers. Le chapitre 3 généralise la construction de ces schémas aux ordres supérieurs, et pour une classe générale d'équations d'évolution non linéaires.La partie II est constituée du chapitre 4, qui génère des constructions d'ordre élevé dans le cadre de conditions initiales aléatoires.Finalement, la partie III se consacre à l'étude en temps long d'équations dispersives, et de leurs invariants, en considérant des schémas préservant leur structure. Elle débute avec le chapitre 5, qui introduit un nouvel intégrateur symétrique pour l'équation de Schrödinger non linéaire, et démontre des résultats de convergence à des taux fractionnaires, en fonction de la régularité de Sobolev de la donnée initiale. Par la suite, le chapitre 6 étend cette construction symétrique aux ordres supérieurs et pour la résolution numérique d'une classe générale d'équations dispersives. Des simulations numériques montrent que ces nouveaux schémas symétriques présentent d'excellentes propriétés de préservation de la structure.Les extensions aux ordres supérieurs développées aux chapitres 3, 4, et 6 se fondent sur de nouvelles techniques d'arbres décorés, inspirées par le champ des EDP stochastiques singulières, via la théorie des structures de régularité
The work presented in this thesis belongs to the field of numerical analysis, and builds on tools stemming from the study of partial differential equations (PDEs). We focus on time discretizations to nonlinear dispersive equations. The aim is to reduce the smoothness assumptions on the design and analysis of numerical methods, in order to treat low-regularity dynamics.Part I of the thesis develops novel low-regularity schemes, suited for general bounded domains. Chapter 2 presents first and second order convergence results for the Gross-Pitaevskii equation, when both the initial data and the potential are non-smooth. Chapter 3 generalizes the construction of these schemes to higher order and to a general class of nonlinear evolution equations with potentials.Part II of the thesis consists of Chapter 4, which considers higher-order constructions for randomized initial conditions. Part III of the thesis considers the long-time properties and invariants of the equation, and deals with structure-preserving schemes. We first introduce in Chapter 5 a novel symmetric time integrator for the nonlinear Schr ̈odinger equation. We give fractional convergence rates as a function of the Sobolev regularity of the initial data. Chapter 6 extends the latter work by constructing higher order symmetric integrators for a general class of dispersive equations. All these new symmetric schemes exhibit excellent structure preservation and convergence properties, which are witnessed in numerical experiments.The higher order extensions of Chapters 3, 4, 6 follow new techniques based on decorated tree series, inspired by singular stochastic PDEs via the theory of Regularity Structures

Abstract:
This chapter begins by proving Baker-DeMarco's conjecture characterizing curves in the moduli space of complex polynomials containing an infinite set of PCF parameters. It then investigates a combinatorial classification of special curves inspired by the classification of PCF polynomials in terms of Hubbard trees. More precisely, the chapter seeks a one-to-one correspondence between special curves and decorated graphs, but due to the presence of symmetries, this task turns out to be delicate to achieve. The chapter focuses on presenting a partial correspondence encoding a large class of special curves by a combinatorial gadget that can be called critically marked dynamical graphs. It then shows how to associate a marked dynamical graph to an irreducible curve, and defines the category of special graphs.

Abstract:
Abstract Outgroup comparison is a special case of the more general use of parsimony in the construction of unrooted trees. The ultimate product of such analyses would be a ‘global’ unrooted tree connecting all species. A direct method for polarizing characters is needed to root such a tree. I argue that Nelson’s restated biogenetic law is one member of a class of direct methods of char acter analysis that share the same logical basis: parsimony-based analysis of hierarchically nested, homologous characters. Nested characters may be sets of ontogenetic homologues, linked by ontogenetic transformation, organogenetic transformation, or biosynthetic pathways; or sets of iterative homologues, such as serial homologues and paralogous genes. These methods can be used to decorate a tree with arrows that point towards its root. Phylogenetic loss may result in character distributions that are ambiguous or misleading, or for which the methods are inapplicable. The only assumption required beyond those inherent in parsimony-based construction of unrooted trees is that every homology represents a synapomorphy at some level. Nelson’s ‘ontogenetic criterion’ does not assume that phylogenetic change occurs exclusively or predominantly through terminal ontogenetic addition.

Abstract:
Abstract In the tribal societies in which all religions arose it would be difficult to separate out a religious belief component from the social practices of the tribe. Rituals centered on annual events of hunting, planting, and major seasonal changes, and would have involved attempted communication with the spirit powers which controlled such things, and rites to ensure fertility and success in the hunt. Rites often continue after such beliefs die out: many people bring trees into their homes at Christmas and decorate them, without believing that they are dressing and feeding the tree god and invoking his power to bring Winter to an end.

Abstract:
The aim of the research is to investigate the symbols of birds on the furniture artefacts stored in the National Museum of Lithuania: dowry chests. In general, Lithuanian ethnic culture can be called “a tree culture”. The main construction and equipment material of Lithuanian dwellings was wood. Lithuanians made all household items, furniture, as well as work tools from wood. Wood is also the main material for furniture. As far as it is known, Lithuanian peasants loved to decorate, to paint mostly the dowry chests and the cabinets. The decoration of cabinets with polychromatic painting is identical to the decoration of dowry chests (however, the decoration of cabinets began later than that of the dowry chests).

Abstract:
Abstract In the mid-1600s, Mohegans living in eastern Connecticut interred several bodies at their principal burial ground, near modern-day Norwich. Along with the body of Lucy Occum, who had been converted to Christianity yet was also a medicine woman, the Mohegans had placed a bowl inlaid with wampum, the brightly colored cylindrical beads often used as currency in Indian transactions. With Hannah Wequot, the daughter of Chief Uncas, a seventeenth-century Mohegan leader, they had buried a bowl carved from a pepperidge tree knot and decorated with the figure of an owl. With a third, unknown Mohegan they had included a small “Hobbomocko” doll used to ward off evil spirits. In 1868, looters invaded the Mohegan burial mound, scattering skeletons and removing hundreds of items buried with them, including the Hobbomocko doll and the bowls buried with Lucy Occum and Hannah Uncas. The looters sold most of the items they retrieved to collectors, and some later found their way to museums.

Abstract:
The paper describes Late Roman and Early Byzantine decorated fine ware vessels and fragments found on both sides of the Kerch Strait (city of Kytaia, Džurg-Oba necropolis and fortlet Il’ičevskoe), and in Chersonesos. The finds represent the recently identified group of fine ceramics called Late Roman Pontic Burnished Ware. They are characterized by very re fined, pale pinkish - light brownish clay containing some very fine flakes of mica and single lumps of lime of various sizes. The inside surface of the dishes is carefully burnished, producing a slight lustre, and contains elaborated decoration executed by delicate incising in dried clay after burnishing and before firing (sgraffito-like technique). The decorative compositions contain centrally placed big cross, in two cases flanked by palm-branches or cypresses of similar size, and in one case completed with representation of four birds between arms of the cross. The central compositions are surrounded by two concentric grooved lines accompanied in two cases by a long spiral scratched on their outside. The outer surface of the examined dishes was finished with less care, it has some turning marks and a dull appearance. The jugs with their burnished surfaces bear incised decoration in the upper part of their bodies. In both cases, it contains a friese composed of simple motifs such as palm trees and branches, threeleaf branches and rope patterns

Abstract:
Special communities specific to Autism Spectrum disorder face difficulties both socially and communicably [1]. Autism spectrum disorder will affect their expression and response to society, and they'll have a hard time learning and following complex directions [2]. This paper proposes software to promote one's collaborative skills and drawing skills with interaction with the AI system. At the same time, it also tries to raise awareness of the special group in our society. As an open platform, each individual will have opportunities to work with other users to cooperate, and they'll have a chance to learn drawing step by step from drawing that is contributed by more than 15 million players around the world. They can decorate the object with a color adjective to enhance their sense of beauty. In order to test the usability of the software, we did two experiments to test the accuracy of the graph and color combination. The result shows this software achieves a high accuracy on color input and obtains a correct graph from the input.

Abstract:
Abstract There is an unmet need for a clean perforating tunnel, for deep-water natural completions that reduces fluid friction, providing better reservoir connectivity and thus enhanced production. As a disruptive innovator in the technology space, particularly in the energy sector, we have now bridged this technology gap through the synthesis of a novel alloy, which when cold isostatic pressed into a conical shaped charge liner enables a unique response. During the detonation event, the jet created from our novel degradable liner punctures the casing and progresses to penetrate the formation until an eventual collapse. Our novel material is designed such that, during detonation, reaction products, bulk metallic glasses (BMG) and/or high entropy alloys (HEA), are formed which disintegrate into a fine powdery debris in contact with water. These degradable BMG/HEA or complexions are preferentially segregated at interfaces with high free energy. They tend to decorate the grain boundaries and domain interfaces of the impermeable skin lining the crushed zone of the perforation tunnel as amorphous intergranular films (AIFs) and plug at end of the pathway. Interacting with flowback fluids the complexions promote grain dropping, disintegrating the liner and carrot leaving behind a clean perforation tunnel. As a result, it is projected that fracture conductivity is significantly improved, resulting in enhanced productivity. In addition, a clear perf-tunnel has zero skin value. As such, when compared to a coated tunnel with gun and charge debris, it needs little or no acid to clean-up. In addition, it is anticipated that this will reduce the formation breakdown and opening pressures offering improved economics for the client. Last but not least, this leads to cost reduction of authorized field expenditure (AFE) to support optimized performance of completion designs allowing for increased production. The additional novelty of our liner designed through powder metallurgy (PM) techniques is a sub-sonic deflagration of the jet, during its collapse, resulting in sputtering of complexions and BMG/HEA residue along the perforation tunnel. These sputter-deposited jet complexions react with fluids during flowback, selectively being etched, barely needing water for the clean-up. The disintegration of this skin and slug, if any, in the perf-tunnel into fine particulates, subsequently being removed, leaves behind a clear, clean tunnel. CLEAR shaped charges have now been qualified to customer specifications in field conditions and are ready to be commercialized. Our journey of innovation does not end here. In fact, this is not even the beginning of the end, but it is, perhaps, the end of the beginning. To offset our carbon footprint and having embraced environmental and natural resources stewardship as one of our core values we are committed to contributing, as individuals and as an organization, to a flourishing human-ecological system. Through technology synthesis we have developed the concept of engineering seedpods for sustainable reforestation and Agri-tech. This had led to an endeavor for rapid tree planting through areal drones and UAVs’ to offset the effects of deforestation caused by human activities and natural disasters. In our paper we will additionally highlight this innovative technology cross-pollination and our efforts in low carbon and ESG endeavors.
