Abstract:
Sierpi?ski graphs Sn p form an extensively studied family of graphs of fractal nature applicable in topology, mathematics of the Tower of Hanoi, computer science, and elsewhere. An almost-extreme vertex of Sn p is introduced as a vertex that is either adjacent to an extreme vertex of Sn p or is incident to an edge between two subgraphs of Sn p isomorphic to Snp-1. Explicit formulas are given for the distance in Sn p between an arbitrary vertex and an almostextreme vertex. The formulas are applied to compute the total distance of almost-extreme vertices and to obtain the metric dimension of Sie

For a connected graph $G=(V,E)$ of order at least two, a chord of a path $P$ is an edge joining two non-adjacent vertices of $P$. A path $P$ is called a monophonic path if it is a chordless path. A monophonic set of $G$ is a set $S$ of vertices such that every vertex of $G$ lies on a monophonic path joining some pair of vertices in $S$. The monophonic number of $G$ is the minimum cardinality of its monophonic sets and is denoted by $m(G)$. A geodetic set of $G$ is a set $S$ of vertices such that every vertex of $G$ lies on a geodesic joining some pair of vertices in $S$. The geodetic number of

AbstractIn this paper a feasible direction method is presented to find all efficient extreme points for a special class of multiple objective linear fractional programming problems, when all denominators are equal. This method is based on the conjugate gradient projection method, so that we start with a feasible point and then a sequence of feasible directions towards all efficient adjacent extremes of the problem can be generated. Since methods based on vertex information may encounter difficulties as the problem size increases, we expect that this method will be less sensitive to problem siz

Abstract:
This document introduces a method to solve linear optimization problems. The method’s strategy is based on the bounding condition that each constraint exerts over the dimensions of the problem. The solution of a linear optimization problem is at the intersection of the constraints defining the extreme vertex. The method decomposes the n-dimensional linear problem into n-1 two-dimensional problems. After studying the role of constraints in these two-dimensional problems, we identify the constraints intersecting at the extreme vertex. We then formulate a linear equation system that directly lead

In this thesis, the main objects of study are probability measures on the isomorphism classes of countable, connected rooted graphs. An important class of such measures is formed by unimodular measures, which satisfy a certain equation, sometimes referred to as the intrinsic mass transport principle. The so-called law of a finite graph is an example of a unimodular measure. We say that a measure is sustained by a countable graph if the set of rooted connected components of the graph has full measure. We demonstrate several new results involving sustained unimodular measures, and provide thorou

Full text
Abstract:
This chapter offers an overview of the book’s concerns, which are centred on the relationship between the tragic protagonist and the listener or onlooker who stands as witness. In Euripides, Phaedra’s anguished disclosure of her feelings to the Nurse, and the Nurse’s troubling reaction to what she hears, veering between extreme horror and too-familiarising rationalisation, are the starting-point for thinking about the difficulty of communicating tragic experience, which by its nature verges on the unspeakable, and so of finding good witness. The concept of good witness is extended to other terms: finding someone to tell one’s story; hospitality to the alien or stranger; and the ‘holding’ of another’s experience epitomised in the mother’s relation to the child, as in object relations theory (esp. Donald Winnicott). The dual obligation both to enter into the extraordinariness of the protagonist’s experience and to ground it in a world shared in common is discussed in relation to the theatrical representation of madness, particularly in Shakespeare, and to the distinctive resources which theatre can bring. Such witness is expressed as a particular kind of grieving, whose relation to adequate representation is glossed with reference to Gillian Rose’s concept of ‘inaugurated mourning’.

Full text
Abstract:
This chapter examines Volkhovskii’s early life from his birth in 1846 down to his third arrest in 1874. Volkhovskii was born into a comparatively impoverished noble family in modern-day Ukraine. He was at a young age scarred by seeing the harsh treatment of the serfs on his grandfather’s estate, which prompted his sympathy for the plight of the Russian people, and he was while still a teenager already well-versed in the ideas expressed in radical literature (both legal and illegal). He initially came under police supervision in 1866, in part because of his role in running a student organisation suspected of fostering Ukrainian national sentiment, before being arrested two years later for his part in setting up the Ruble Society that sought to build closer links between the intelligentsia and the peasantry. Volkhovskii was eventually released without charge, but within a few months he was arrested again, in part because he was suspected of having ties to Sergei Nechaev, the enfant terrible of the mid-nineteenth-century Russian revolutionary movement, whose sadism and penchant for melodramatic pronouncements alienated many of his fellow revolutionaries. Volkhovskii was again acquitted, after two years in prison, subsequently moving south to Odessa where he established one of the most active groups that made up the Chaikovskii movement. Volkhovskii’s group was extremely well-organised, insisting on the complete commitment of its members, and directed much of its attention to agitation among urban workers rather than the peasantry. Volkhovskii believed for a short time in the late 1860s that a successful revolution could be brought about by a small group committed to seizing power to bring about social and economic revolution. He was, though, for the most part convinced that real change would only come about through a programme of agitation designed to foment a radical outlook among the Russian narod.

Abstract While Chapter XXIV ostensibly concerns the Four Buddhist Truths and the way they are to be understood from the vantage point of emptiness, it is really about the nature of emptiness itself and about the relation between emptiness and conventional reality. As such, it is the philosophical heart of MūlamadhyamakakārikiāThe first six verses of the chapter (XXIV: 1-6) present a reply to Nāgārjuna’ doctrine of emptiness by an opponent charging the doctrine with nihilism. The next eight verses (XXIV: 7-14) are primarily rhetorical, castigating the opponent for his misunderstanding of Mūlamadhyamakakārikiā. The positive philosophical work begins with XXIV: 15. From this point Nāgārjuna’ offers a theory of the relationship between emptiness, dependent origination, and convention and argues not only that these three can be understood as corelative, but that if conventional things (or emptiness itself) were nonempty, the very nihilism with which the reificationist opponent charges Mūlamadhyamakakārikiāwould ensue. This tactic of arguing not only against each extreme but of arguing that the contradictory extremes are in fact mutually entailing is, as we have seen in earlier chapters, a dialectical trademark of Nāgārjuna’;s philosophical method. In this chapter, it is deployed with exceptional elegance and acuity.

The inverse sum indeg (ISI) index of a graph G is defined as the sum of the weights dG(u)dG(v)/dG(u)+dG(v) of all edges uv in G, where dG(u) is the degree of the vertex u in G. This index is found to be a significant predictor of total surface area of octane isomers. In this chapter, the authors present some lower and upper bounds for ISI index of subdivision graphs, t-subdivision graphs, s-sum and st -sum of graphs in terms of some graph parameters such as order, size, maximum degree, minimum degree, and the first Zagreb index. The extremal graphs are also characterized for their sharpness.

Full text
Abstract:
This chapter discusses the addition of nucleophilic reagents to aldehydes and ketones. In the series formaldehyde–acetaldehyde–acetone, reactivity to nucleophiles decreases in that order. The electronic factor here is deactivating, but slight, because the additional Me groups are not attached directly to the carbonyl carbon. They are largely insulated from it by saturated carbon atoms. The chapter then considers high degrees of hydration at equilibrium, which generally result when the carbonyl group has strong electron-withdrawing substituents attached, and in extreme cases it is the hydrate which is the familiar form of the carbonyl compound. It also looks at hemiacetal and hemiketal formation; cyanohydrin formation; bisulfate addition; the Meerwein–Ponndorf–Verley reaction; the Cannizzaro reaction; and reaction with Grignard reagents.

Abstract:
Observam-se atualmente dois fenômenos cujos impactos impõem novos desafios às cidades: mudanças climáticas e envelhecimento populacional. Ao analisar essas duas tendências convergentes, questiona-se como as cidades vêm se adaptando aos cenários de mudanças climáticas dentro de uma agenda inclusiva aos idosos, considerados um dos grupos mais vulneráveis a esses eventos. O objetivo desta pesquisa foi identificar como estão sendo desenvolvidas as estratégias de adaptação e como os idosos estão sendo inseridos nesse planejamento, a partir da análise de Planos de Ação Climática de cidades latino-am

Abstract:
Advances in casting and polishing technology at the Steward Observatory Mirror Laboratory enable the production of astronomical mirrors of unprecedented size and focal ratio. The null correctors required for the interferometric center-of-curvature test of such large optics must also be of unprecedented proportions. To correct for the enormous departure of the mirrors from spherical (5.7 mm from the vertex-matching sphere for 8.4-m f/1.14 Columbus telescope primary) several extreme null lens designs are considered.

Abstract:
Abstract A new degree-four vertex origami, called the Morph pattern, has been recently proposed by the authors (Pratapa, Liu, Paulino, Phy. Rev. Lett. 2019), which exhibits interesting properties such as extreme tunability of Poisson’s ratio from negative infinity to positive infinity, and an ability to transform into hybrid states through rigid origami kinematics. We look at the geometry of the Morph unit cell that can exist in two characteristic modes differing in the mountain/valley assignment of the degree-four vertex and then assemble the unit cells to form complex tessellations that are
