Oil and gas companies' low-carbon emission transition to integrated energy companies

In recent years, with the emphasis on environmental protection, the global energy landscape is changing: the proportion of traditional energy is gradually decreasing, and renewable energy are developing rapidly. In this context, the oil and gas company is also in the early stages of the low-carbon emission energy transition. However, this concept is relatively new for many oil and gas companies. Thus, this paper aims to introduce the low-carbon emission transition practices of several large oil and gas companies so that more companies can learn from the experience. This paper summarizes the transition targets, investment, and actions of some large oil and gas companies employing enterprise surveys, and analyses the low-carbon transition paths, opportunities, and challenges. The analysis shows that (1) vigorous development of natural gas business is the first step for oil and gas companies to transition to low-carbon emission stage; (2) increasing investment in renewable energy is a long-term action of oil and gas companies and the key to transforming oil and gas companies into integrated energy companies; (3) oil and gas companies should have rich experience in developing geothermal energy. In addition, the paper also proposes policy recommendations for the low-carbon transition of oil and gas companies.

Understanding transition pathways by bridging modelling, transition and practice-based studies: Editorial introduction to the special issue

This paper presents an introduction to and overview of the papers in this Special Issue of Technological Forecasting & Social Change on ‘Transition Pathways’ is presented. Each of these papers are an output of the PATHWAYS project (EC FP7-funded, 2013–2017) which looked into ways to integrate alternative approaches for analysing sustainability transitions. Methods to bridge across scenario-modelling, socio-technical transition, and practice-based action research approaches (Turnheim et al. 2015; Geels et al., 2016) were implemented in eight empirical and modelling studies reported here. A variety of approaches to bridging emerged in practice, with differing methodological strategies employed, analysing transitions processes across different sectors, at a range of scales, and separately, comparatively or in a fully integrated way. This paper suggests a framework for understanding different approaches to bridging and shows how policy- and decision-making can be enriched by theoretically- and empirically-informed bridging approaches to transitions analysis.

On some distance-regular graphs with many vertices

We construct distance-regular graphs, including strongly regular graphs, admitting a transitive action of the Chevalley groups $$G_2(4)$$ and $$G_2(5)$$, the orthogonal group O(7, 3) and the Tits group $$T=$$$$^2F_4(2)'$$. Most of the constructed graphs have more than 1000 vertices, and the number of vertices goes up to 28431. Some of the obtained graphs are new.

Abraham J. Heschel e a mística do pathos divino

A categoria do pathos divino ganhou em Abraham Heschel sua expressão mais forte. O profeta não tem ideias e conceitos sobre Deus, o profeta é aquele que sofre uma ação transitiva de Deus. Não se trata de uma fusão com Deus, trata-se de ser afetado pelo pathos de Deus. Para Heschel a experiência mística é um êxtase do ser humano; a revelação é um êxtase de Deus. Não é Deus que é uma experiência do ser humano; o ser humano é que é uma experiência de Deus. Deriva daí não uma mística unitiva propriamente, mas uma mística simpatetica, que se traduz como resposta humana às dores de Deus nas dores do mundo. O que testemunham os profetas não é a essência do divino, mas seu pathos, sua concernência com a miséria humana. O pathos divino é como uma ponte lançada sobre o abismo que separa o ser humano de Deus.

Flexibility of normal affine horospherical varieties

We investigate flexibility of affine varieties with an action of a linear algebraic group. Flexibility of a smooth affine variety with only constant invertible functions and a locally transitive action of a reductive group is proved. Also we show that a normal affine complexity-zero horospherical variety with only constant invertible functions is flexible.

-factorizability of -spaces in the category G-Tych

We introduce and characterize the notion of -factorizability of -spaces in the category G- Tych. For -spaces with -openly acting groups, we establish the equivalence of -factorizability and -factorizability in G-Tych. We prove the -factorizability in G-Tych of every -factorizable -space with transitive action whose phase space possesses the Baire property. The Dieudonné completion of an -factorizable group is shown to be the phase space of a -space -factorizable in G-Tych. We characterize -factorizability in G-Tych under passage to the -compactification.

Conformal superspaces, projectivity and quantization

In this paper we study the complex conformal superspace in D = 4 for N = 1 supersymmetry as a projective superspace. Among the different superspaces that carry a transitive action of the conformal supergroup, the superflag Fl(2|0, 2|1, 4|1) is distinguished as the minimal one that has a reality condition preserved by the real conformal supergroup. As in the non super case, the different flag supermanifolds are related to parabolic subalgebras and imposing the constraint that the reduced manifold must be the Grassmannian Gr(2,4), the complex conformal space, leaves us with five choices, corresponding to the five non isomorphic Borel subalgebras. We identify the ones that are used in physics. As it is well known, not all superflags have a projective embedding, but in the cases of interest one has a super Plucker embedding, so they are projective super varieties. For the superflag Fl(2|0, 2|1, 4|1), this is followed by a super Segre embedding, which then provides a method for its quantization.

On stationary subgroups of compact homogeneous spaces

We study some special properties of stationary subgroups and their Lie algebras of compact homogeneous spaces. We consider the cases of decomposable stationary Lie subalgebras and stationary subalgebras of small dimensions. The case of nonreducible transitive actions of Lie groups is considered in detail.

PERAN SEMANTIS DALAM KONSTRUKSI DATIF BAHASA JEPANG

This study aims to describe the verbs that give rise to dative construction and the semantic roles that arise in dative construction in Japanese sentence structure, which includes the agentif role, benefactive role, experience role, and objective role. The theory used in this study is the theory of Givon (2001), Cook's Case Grammar Theory (1979), and the theory of inheritance from Nitta (1991). Data sources are taken from the Japanese corpus, www.kotonoha.gr.jp/shonagon/
 This research shows Japanese language is a language marked or a file. The case in Japanese here is closely related to the system of inheritance in the Japanese sentence structure. The marker is attached after noun (noun). The markers or particles that state direct objects are accusative markers 'o' and markers datif 'ni' as markers of indirect objects. The verb found in this study is tatakareta 'has been tapped', yonde kureta 'has read', tooraseta 'has (caused) passed', and oboeta 'has remembered' which can bring up multiple objects, namely the order of direct objects and indirect objects. The results of this study, (1) show the verbs that allow the emergence of multiple objects, especially indirect objects (IO) in the construction of Japanese, are transitive verbs or action verbs and intransitive verbs in the form of idou doushi 'moving verbs' are causative in Japanese language {~ exciting / ~ saseru} means to make / cause, and (2) the semantic roles that arise in the dative construction of Japanese sentence structures (BJ) include (a) agentive roles, (b) benefactive roles, (c) experience roles, and (c) objective roles. Semantically the verbs that give rise to the semantic role are keizoku doushi 'continuous verbs' and shunkan doushi 'pungtual verbs'.

Grammar, Gender and Demonstratives in Lateralized Imagery for Sentences.

We investigated biases in the organization of imagery by asking participants to make stick-figure drawings of sentences containing a man, a woman and a transitive action (e.g. she kisses that guy). Previous findings show that prominent features of meaning and sentence structure are placed to the left in drawings, according to reading direction (e.g. Stroustrup and Wallentin in Lang Cogn 10(2):193-207, 2018. https://doi.org/10.1017/langcog.2017.19 ). Five hundred thirty participants listened to sentences in Danish and made eight drawings each. We replicated three findings: (1) that the first mentioned element is placed to the left more often, (2) that the agent in the sentence is placed to the left, and (3) that the grammatical subject is placed to the left of the object. We further tested hypotheses related to deixis and gender stereotypes. By adding demonstratives (e.g. Danish equivalents of this and that), that have been found to indicate attentional prominence, we tested the hypothesis that this is also translated into a left-ward bias in the produced drawings. We were unable to find support for this hypothesis. Analyses of gender biases tested the presence of a gender identification and a gender stereotype effect. According to the identification hypothesis, participants should attribute prominence to their own gender and draw it to the left, and according to the stereotype effect participants should be more prone to draw the male character to the left, regardless of own gender. We were not able to find significant support for either of the two gender effects. The combination of replications and null-findings suggest that the left-ward bias in the drawing experiment might be narrowly tied to left-to-right distribution in written language and less to overall prominence. No effect of handedness was observed.

Nearly Approximate Transitivity (AT) for Circulant Matrices

AbstractBy previous work of Giordano and the author, ergodic actions of $\mathbf{Z}$ (and other discrete groups) are completely classified measure-theoretically by their dimension space, a construction analogous to the dimension group used in $\text{C}^{\ast }$-algebras and topological dynamics. Here we investigate how far from approximately transitive (AT) actions can be that derive from circulant (and related) matrices. It turns out not very: although non-AT actions can arise from this method of construction, under very modest additional conditions, approximate transitivity arises. KIn addition, if we drop the positivity requirement in the isomorphism of dimension spaces, then all these ergodic actions satisfy an analogue of AT. Many examples are provided.

Gesture Recognition in Augmented Reality Assisted Assembly Training

The Augmented Reality assisted assembly training (ARAAT) is an effective and low-cost way in motor and electronic industry. In ARAAT, assembly operations are the processes which mainly use the AR device to recognize the gestures and match the virtual workpieces to the hand based on the consistency of time and space. Operations are recorded to the video by an AR device. By dealing with frames of the input video, operations can be distinguished. In this paper, a gesture recognition algorithm in ARAAT are proposed. The assembly training operations consist of several actions and actions we concerned are all conducted by gestures. Operations can be classified from the sequences of actions, that is, gestures. Every 20 frames of the input video are denoted as an action unit and the action unit slides with a time window. According to the 2D and 3D features of the action unit, a scorer trained by the samples of specific actions gives the optimal label of each frame to recognize the action. To avoid the disturbance of the transition and invalid action to the action boundary during the recognition, the boundary is iteratively optimized by the probability density distribution. The proposed algorithm implemented on HoloLens is compared with other algorithms. The experimental results indicate that the proposed algorithm achieves a high recognition rate and can reduce the computational complexity. The results prove the efficiency of recognition algorithm in ARAAT and ensure a friendly experience for the human-machine interaction.

Predicting Object-Mediated Gestures From Brain Activity: An EEG Study on Gender Differences.

Recent functional magnetic resonance imaging (fMRI) studies have identified specific neural patterns related to three different categories of movements: intransitive (i.e., meaningful gestures that do not include the use of objects), transitive (i.e., actions involving an object), and tool-mediated (i.e., actions involving a tool to interact with an object). However, fMRI intrinsically limits the exploitation of these results in a real scenario, such as a brain-machine interface. In this paper, we propose a new approach to automatically predict intransitive, transitive, or tool-mediated movements of the upper limb using electroencephalography (EEG) spectra estimated during a motor planning phase. To this end, high-resolution EEG data gathered from 33 healthy subjects were used as input of a three-class k-nearest neighbors classifier. Different combinations of EEG-derived spatial and frequency information were investigated to find the most accurate feature vector. In addition, we studied gender differences further splitting the dataset into only-male data, and only-female data. A remarkable difference was found between accuracies achieved with male and female data, the latter yielding the best performance (78.55% of accuracy for the prediction of intransitive, transitive, and tool-mediated actions). These results potentially suggest that different gender-based models should be employed for the future BMI applications.

Dual and almost-dual homogeneous spaces

We study homogeneous spaces such that the transitive action of the Lie group on preserves the structure of a dual or almost- dual manifold. We consider general homogeneous spaces of this kind as well as compact or lower- dimensional ones.

Actions of Semitopological Groups

AbstractWe investigate continuous transitive actions of semitopological groups on spaces, as well as separately continuous transitive actions of topological groups.

Natural Law and Friendship with God

Natural Law and Friendship with God Scott Roniger NEAR THE BEGINNING of book VII of the Eudemian Ethics, Aristotle says that the function (ergon) of the political art (politikēs) is the making of friendship (poiēsai philian).1 Near the start of book VIII of the Nicomachean Ethics, he says, "It seems too that friendship holds cities together and that lawgivers (nomothetai) are more serious about it than about justice. For oneness of mind (homonoia) seems to resemble friendship, and lawgivers aim at this especially."2 The legislator possessed of the political art and prudence to legislate well for the common good has the natural end, as legislator, of forming friendships amongst his citizens by ordering the polity in such a way as to make it fertile soil for the growth of oneness of mind and life characteristic of friends. Saint Thomas Aquinas, devoted student of Aristotle that he was, argues that "every law aims [tendit] at establishing the friendship either of men with one another or of man with God."3 [End Page 237] Aquinas articulates the end (finis) of law in various ways: the common good, communal happiness, virtue, and, as we have just seen, friendship.4 These various descriptions of the end of law add nuance to his treatment of law, and they are not unrelated to each other. I wish to suggest that friendship has a kind of governing role over the other descriptions of the end of law. The common good of a polity, its communal happiness in the life of virtue, is founded upon and culminates in the various forms of familial, utilitarian, civic, and virtuous friendships that excellent law makes possible and encourages. Near the beginning of book I of De libero arbitrio, St. Augustine (through Evodius) distinguishes between the temporal, man-made law of a given polity and the eternal law upon which it is based.5 Aquinas, devoted student of St. Augustine that he was, clearly distinguishes human and divine law, and he correlates friendship amongst men with human law and friendship between man and God with divine law. "For just as the main intention [intentio principalis] of human law is to establish friendship of men with one another, so too the intention of divine law is mainly to establish man's friendship with God."6 Human law aims at the constitution of human friendship, and divine law aims at the constitution of friendship between human beings and God. With this framework in place, we raise the question that we wish to discuss in this paper: In light of what has been said about human law and divine law, what can be said about the natural law? Does the natural law aim at friendship amongst men themselves or friendship between men and God?7 Developing an [End Page 238] adequate answer to this question will require us to raise and respond to related philosophical questions and, in the final section of this paper, to go beyond philosophical thinking by reflecting theologically on human friendship with God in light of God's revelation.8 I. Natural Law as Divine Law The first step in answering our question is to determine whether the natural law is a human law or a divine law. To this end, it is important to recall Aristotle's distinction between immanent and transitive actions and to see that legislating is a transitive action. Immanent actions, such as seeing and thinking, remain "within" the agent, while transitive actions, such as building and cutting, "stretch out" from the agent and terminate in something external to him. The activity of legislating originates with the active thinking and directing decisions of the legislator and terminates in the shaped thinking and directed actions of the citizens subject to him. As Aquinas says, law can exist in two ways: "In one way, as in the measurer and ruler. And since this is proper to reason, law in this sense is in reason alone. In another way, as in the ruled and measured. And this is how law exists in [End Page 239] all the things that are inclined in any way by any kind of law."9 Although it...

GEOMETRIC BIJECTIONS FOR REGULAR MATROIDS, ZONOTOPES, AND EHRHART THEORY

Let$M$be a regular matroid. The Jacobian group$\text{Jac}(M)$of$M$is a finite abelian group whose cardinality is equal to the number of bases of$M$. This group generalizes the definition of the Jacobian group (also known as the critical group or sandpile group)$\operatorname{Jac}(G)$of a graph$G$(in which case bases of the corresponding regular matroid are spanning trees of$G$). There are many explicit combinatorial bijections in the literature between the Jacobian group of a graph$\text{Jac}(G)$and spanning trees. However, most of the known bijections use vertices of$G$in some essential way and are inherently ‘nonmatroidal’. In this paper, we construct a family of explicit and easy-to-describe bijections between the Jacobian group of a regular matroid$M$and bases of$M$, many instances of which are new even in the case of graphs. We first describe our family of bijections in a purely combinatorial way in terms of orientations; more specifically, we prove that the Jacobian group of$M$admits a canonical simply transitive action on the set${\mathcal{G}}(M)$of circuit–cocircuit reversal classes of$M$, and then define a family of combinatorial bijections$\unicode[STIX]{x1D6FD}_{\unicode[STIX]{x1D70E},\unicode[STIX]{x1D70E}^{\ast }}$between${\mathcal{G}}(M)$and bases of$M$. (Here$\unicode[STIX]{x1D70E}$(respectively$\unicode[STIX]{x1D70E}^{\ast }$) is an acyclic signature of the set of circuits (respectively cocircuits) of$M$.) We then give a geometric interpretation of each such map$\unicode[STIX]{x1D6FD}=\unicode[STIX]{x1D6FD}_{\unicode[STIX]{x1D70E},\unicode[STIX]{x1D70E}^{\ast }}$in terms of zonotopal subdivisions which is used to verify that$\unicode[STIX]{x1D6FD}$is indeed a bijection. Finally, we give a combinatorial interpretation of lattice points in the zonotope$Z$; by passing to dilations we obtain a new derivation of Stanley’s formula linking the Ehrhart polynomial of$Z$to the Tutte polynomial of$M$.

Transition-Based Korean Dependency Parsing Using Hybrid Word Representations of Syllables and Morphemes with LSTMs

Recently, neural approaches for transition-based dependency parsing have become one of the state-of-the art methods for performing dependency parsing tasks in many languages. In neural transition-based parsing, a parser state representation is first computed from the configuration of a stack and a buffer, which is then fed into a feed-forward neural network model that predicts the next transition action. Given that words are basic elements of a stack and buffer, a parser state representation is considerably affected by how a word representation is defined. In particular, word representation issues become more critical in morphologically rich languages such as Korean, as the set of potential words is not bound but introduce the second-order vocabulary complexity, called the phrase vocabulary complexity due to the agglutinative characteristics of the language. In this article, we propose a hybrid word representation that combines two compositional word representations, each of which is derived from representations of syllables and morphemes , respectively. Our underlying assumption for this hybrid word representation is that, because both syllables and morphemes are two common ways of decomposing Korean words, it is expected that their effects in inducing word representation are complementary to one another. Experimental results carried on Sejong and SPMRL 2014 datasets show that our proposed hybrid word representation leads to the state-of-the-art performance.

Topological transitivity and wandering intervals for group actions on the line $\mathbb R$

For every group G , we show that either G has a topologically transitive action on the line \mathbb R by orientation-preserving homeomorphisms, or every orientation-preserving action of G on \mathbb R has a wandering interval. According to this result, all groups are divided into two types: transitive type and wandering type, and the types of several groups are determined. We also show that every finitely generated orderable group of wandering type is indicable. As a corollary, we show that if a higher rank lattice \Gamma € is orderable, then € \Gamma is of transitive type.

The homology core of matchbox manifolds and invariant measures

We consider the topology and dynamics associated with a wide class of matchbox manifolds, including spaces of aperiodic tilings and suspensions of higher rank (potentially nonabelian) group actions on zero-dimensional spaces. For such a space we introduce a topological invariant, the homology core, built using an expansion of it as an inverse sequence of simplicial complexes. The invariant takes the form of a monoid equipped with a representation, which in many cases can be used to obtain a finer classification than is possible with the previously developed invariants. When the space is obtained by suspending a topologically transitive action of the fundamental group $ \Gamma $ of a closed orientable manifold on a zero-dimensional compact space $ Z$, this invariant corresponds to the space of finite Borel measures on $ Z$ which are invariant under the action of $ \Gamma $. This leads to connections between the rank of the core and the number of invariant, ergodic Borel probability measures for such actions. We illustrate with several examples how these invariants can be calculated and used for topological classification and how it leads to an understanding of the invariant measures.
