Action Unit Detection

Facial Action Units (AUs) correspond to the deformation/contraction of individual facial muscles or their combinations. As such, each AU affects just a small portion of the face, with deformations that are asymmetric in many cases. Generating and analyzing AUs in 3D is particularly relevant for the potential applications it can enable. In this paper, we propose a solution for 3D AU detection and synthesis by developing on a newly defined 3D Morphable Model (3DMM) of the face. Differently from most of the 3DMMs existing in the literature, which mainly model global variations of the face and show limitations in adapting to local and asymmetric deformations, the proposed solution is specifically devised to cope with such difficult morphings. During a training phase, the deformation coefficients are learned that enable the 3DMM to deform to 3D target scans showing neutral and facial expression of the same individual, thus decoupling expression from identity deformations. Then, such deformation coefficients are used, on the one hand, to train an AU classifier, on the other, they can be applied to a 3D neutral scan to generate AU deformations in a subject-independent manner. The proposed approach for AU detection is validated on the Bosphorus dataset, reporting competitive results with respect to the state-of-the-art, even in a challenging cross-dataset setting. We further show the learned coefficients are general enough to synthesize realistic 3D face instances with AUs activation.

In this article, we explore the debates surrounding the proposed canonization of Archbishop Oscar Romero, an outspoken defender of human rights and the poor during the civil war in El Salvador, who was assassinated in March 1980 by paramilitary death squads while saying Mass. More specifically, we examine the tension between, on the one hand, local and popular understandings of Romero’s life and legacy and, on the other hand, transnational and institutional interpretations. We argue that the reluctance of the Vatican to advance Romero’s canonization process has to do with the need to domesticate and “privatize” his image. This depoliticization of Romero’s work and teachings is a part of a larger agenda of neo-Romanization, an attempt by the Holy See to redeploy a post-colonial and transnational Catholic regime in the face of the crisis of modernity and the advent of postmodern relativism. This redeployment is based on the control of local religious expressions, particularly those that advocate for a more participatory church, which have proliferated with contemporary globalization

Starting from the cry of the seraphim in Isaiahʹ s prophecy, this article aims to follow the rhythm of the sacred harmony, transcending the symbols of the angelic world and of the divine names, to get to the face to face meeting between man and God, just as the seraphim, reflecting their existence, stand face to face. The finality of the sacred harmony is that, during the search for God inside the human being, He reveals Himself, which is the reason for the affirmation of “I Am that I Am.” Through its hypnotic cyclicality, the profane temporality has its own musicality. Its purpose is to incubate the unsuspected potencies of the beings “caught” in the material world. Due to the fact that it belongs to the aeonic time, the divine music will exceed in harmony the mechanical musicality of profane time, dilating and temporarily cancelling it. Isaiah is witness to such revelation offering access to the heavenly concert. He is witness to divine harmonies produced by two divine singers, whose musical history is presented in our article. The seraphim accompanied the chosen people after their exodus from Egypt. The cultic use of the trumpet is related to the characteristics and behaviour of the seraphim. The seraphic music does not belong to the Creator, but its lyrics speak about the presence of the Creator in two realities, a spiritual and a material one. Only the transcendence of the divine names that are sung/cried affirms a unique reality: God. The chant-cry is a divine invocation with a double aim. On the one hand, the angels and the people affirm God’s presence and call His name and, on the other, the Creator affirms His presence through the angels or in man, the one who is His image and His likeness. The divine music does not only create, it is also a means of communion, implementing the relation of man to God and, thus, God’s connection with man. It is a relation in which both filiation and paternity disappear inside the harmony of the mutual recognition produced by music, a reality much older than Adam’s language.

Ideas of nationalisms as masculine projects dominate literary texts by African male writers. The texts mirror the ways in which gender differentiation sanctions nationalist discourses and in turn how nationalist discourses reinforce gender hierarchies. This article draws on theoretical insights from the work of Anne McClintock and Elleke Boehmer to analyse two plays: Zintgraff and the Battle of Mankon by Bole Butake and Gilbert Doho and Hard Choice by Sunnie Ododo. The article argues that women are represented in these two plays as having an ambiguous relationship to nationalism. On the one hand, women are seen actively changing the face of politics in their societies, but on the other hand, the means by which they do so reduces them to stereotypes of their gender.

Abstract Extraction of causal relations between biomedical entities in the form of Biological Expression Language (BEL) poses a new challenge to the community of biomedical text mining due to the complexity of BEL statements. We propose a simplified form of BEL statements [Simplified Biological Expression Language (SBEL)] to facilitate BEL extraction and employ BERT (Bidirectional Encoder Representation from Transformers) to improve the performance of causal relation extraction (RE). On the one hand, BEL statement extraction is transformed into the extraction of an intermediate form—SBEL statement, which is then further decomposed into two subtasks: entity RE and entity function detection. On the other hand, we use a powerful pretrained BERT model to both extract entity relations and detect entity functions, aiming to improve the performance of two subtasks. Entity relations and functions are then combined into SBEL statements and finally merged into BEL statements. Experimental results on the BioCreative-V Track 4 corpus demonstrate that our method achieves the state-of-the-art performance in BEL statement extraction with F1 scores of 54.8% in Stage 2 evaluation and of 30.1% in Stage 1 evaluation, respectively.

Workflow management promises a new solution to an age-old problem: controlling, monitoring, optimizing and supporting business processes. What is new about workflow management is the explicit representation of the business process logic which allows for computerized support. This paper discusses the use of Petri nets in the context of workflow management. Petri nets are an established tool for modeling and analyzing processes. On the one hand, Petri nets can be used as a design language for the specification of complex workflows. On the other hand, Petri net theory provides for powerful analysis techniques which can be used to verify the correctness of workflow procedures. This paper introduces workflow management as an application domain for Petri nets, presents state-of-the-art results with respect to the verification of workflows, and highlights some Petri-net-based workflow tools.

Despite the great interest that the scientific community has in quantum computing, the scarcity and high cost of resources prevent to advance in this field. Specifically, qubits are very expensive to build, causing the few available quantum computers are tremendously limited in their number of qubits and delaying their progress. This work presents new reversible circuits that optimize the necessary resources for the conversion of a sign binary number into two's complement of N digits. The benefits of our work are two: on the one hand, the proposed two's complement converters are fault tolerant circuits and also are more efficient in terms of resources (essentially, quantum cost, number of qubits, and T-count) than the described in the literature. On the other hand, valuable information about available converters and, what is more, quantum adders, is summarized in tables for interested researchers. The converters have been measured using robust metrics and have been compared with the state-of-the-art circuits. The code to build them in a real quantum computer is given.

The Aviation Group of the Ministry of Technology (formerly the Ministry of Aviation) is responsible for spending a large part of the country's defence budget, both in research and development on the one hand and production or procurement on the other. In addition, it has responsibilities in many non-defence fields, mainly, but not exclusively, in aerospace.Few developments have been carried out entirely within the Ministry's own Establishments; almost all have required continuous co-operation between the Ministry and Industry. In the past the methods of management and collaboration and the relative responsibilities of the Ministry and Industry have varied with time, with the type of equipment to be developed, with the size of the development project and so on. But over the past ten years there has been a growing awareness of the need to put some system into the complex business of translating a requirement into a specification and a specification into a product within reasonable bounds of time and cost.

Ambiguous Position

In the face of a new serious crisis in Europe caused by the coronavirus pandemic, Russia has taken an ambiguous position. On the one hand, it was spreading fake news and, on the other hand, it was providing Italy with symbolic support. Russia’s immediate goal was to persuade the European Union (EU) to reduce or lift sanctions. The new situation provides a new argument to those participants of the European debate who are in favour of normalisation and even reset of relations with Russia. Among them, the voice of France is particularly clear since its President Emanuel Macron has taken up the initiative to build the ‘architecture of trust and security’ with Russia. These proposals, which are now quite vague, are based on questionable  assumptions and deepen divisions in Europe and the crisis in transatlantic relations. By rising Moscow’s hopes for some form of (geo)political bargain, they in fact encourage Russia to continue its aggressive policy towards its European neighbours. An alternative approach based on several principles is needed in the debate on EU policy towards Russia: developing all five Mogherini’s points; maintaining sanctions against Russia until the reasons for their introduction cease to exist; symmetry of commitments and benefits related to limited cooperation with Russia; inviolability of key interests, security and sovereignty of EU and NATO member and partner states; and balancing the dialogue with the Russian authorities by supporting Russian civil society. Europe can survive without Russia but Russia cannot survive without Europe, which is why European policy needs consistency and strategic patience.

The Mexican economy has a fragile and inefficient financing structure for the productive sector; which acquires great relevance in the face of the imminent economic recession that will follow the most critical period of the Covid-19 pandemic. In this paper, the evolution of the different financing channels is analyzed, in order to know, on the one hand, the composition of the financing of companies; and on the other hand, identify the type of company that presents the highest degree of vulnerability and that, therefore, the government should prioritize. For this, a statistical analysis is carried out both of the composition of the financing of the companies; as well as the characteristics of these companies and their relevance in the economic dynamics of the country.

Organized only two years after the previous genera! elections, the 1987 poll, characterized by a great stability of the electorale, wilt probably have a deep political impact on the country's future.If the rate of external mobility suitably gauges the extent of the citizens' shifts in votes, the 1987 elections will have ranged among the four most stable general elections out of the twenty-two that have taken place since universal suffrage has been introduced. And yet, because of the decline of the outgoing coalition, on the one hand, which is mainly due to the loss suffered by the CVP, and because of the change of majority within the Walloon Regional Council and the French-speaking Community Council, on the other, the political situation appears very different after the 13th December 1987 elections. The observer can only be struck by the asymmetrical behaviour of the voters in the northern and southern parts of the country. In Flanders, the main party is on the decline white all other parties are winning votes.However, everything seems to show that the motivation of the voters who did not vote twice for the same party in 1985 and 1987, but who, as we said, are not very numerous, was an economic and social motivationrather than a language or community-related one. The gains of Agalev, the PVV and the SP in the face of the Volksunie's status quo cannot be explained otherwise. The gains of the Vlaams Blok, notably in Antwerp, are probably due to social (attitude towards immigrants) rather than community-linked motivations too. In the W alloon Region, on the contrary, the main party is registering an obvious gain, white the other parties are declining or stagnating. In this case, the motivations seem to be numerous : they have a social and economic background on the part of voters who trusted the main opposition party, but they are also community linked and inspired by considerations that have to do with the relationships between the Walloon and Flemish people in the Belgian State under transformation.The political prospects then appear uncertain. This is even more true that two other elections are to take place in the next eighteen months.These concern the opposite levels of the elected Assemblies: the municipal Council and the European Parliament.
