This paper focuses on the implementation of a hardware coprocessor intended to speed up multiplications over the  F p 2 finite field extension in the context of bilinear pairings. Being aware of the high degree of parallelism present at different levels of pairings computation, especially in the case of F p 2  multiplications, we propose a hardware architecture based on internal and external pipeline structures allowing both, to accelerate a single multiplication and perform several multiplications in parallel. This enables the development of a hybrid hardware/software solution on a SoC-FPGA for computing bilinear pairings that improves the performance of equivalent state-of-the-art implementations up to a 22.5 %

Automating the measurement of arterial blood pressure (ABP) remains an ongoing challenge. In a recent paper, a proposal is presented to automate the measurement of PSA based on the pulse transit time or (PTT), measured between the electrocardiographic (ECG) R-peaks and the peaks maximum slope of the oscillometric signal. In this research the method was evaluated; noticing loss of information regarding the pulse amplitude, increased distortion of the envelope and rising measurement system. However, it provides a reference to the ECG signal so that it is proposed to integrate with other methods of measuring PSA greater degree of robustness to motion artifacts.

The present reflection openly opposes that obstinate university current that in Costa Rica looks at Roman Law with contempt and that, without major bases of support, considers it as a matter that consists of little less than a waste of time. Keeping in mind the fate of solitude that sometimes accompanies the bona fide jurist, these heterogeneous reasons have been founded against the current in an attempt to deny with grounds the echo of voices that with modernist —or perhaps, populist— eagerness raise their perfidious flags pretending to publicize with contempt everything inherited from the processes of historical-dogmatic formation of legal institutions.

In Latin America, the states have been obliged through their legal systems to guarantee, promote and protect the right to health, even the majority include it in their Magna Cartas. This study proposes an analysis of the situation of various Latin American countries that have positivized the right to health in their internal regulations, in addition to containing mechanisms to take legal action in order to defend the right. The case of Mexico, Guatemala, Brazil, Argentina and Costa Rica is analyzed. In these countries, the instances responsible for the provision of health services constantly disrespect people's rights, which has led to an increase in the use of judicial tools to assert their rights, due to the inefficiency of administrative channels. Having to even reach the Inter-American Court of Human Rights itself in an attempt to protect their right to health. Health systems need to seek to establish mechanisms that detect human rights violations and take corrective action.

This paper deals with partial results from interdisciplinary research. These results contribute to the understanding of the phenomenon of public debt and specifically the debt system as it is understood in the context of global financialization; this phenomenon is expressed in the prominence of financial capital and the concentration of power in actors linked to stock market experiences. At the same time, the interpretation of banking secrecy in this context reveals a dichotomy between public interest and private interest.

Through this study, the irradiating effectiveness of the principle of constitutional supremacy and the direct and immediate effectiveness of fundamental rights is developed, in the context of the relationships that occur between individuals, which is known as horizontal effectiveness of such rights. The analysis focuses its study both on rehearsing a definition of the figure, as well as on a review of the main sentences adopted by the Constitutional Chamber, in the exercise of its function of protection of fundamental rights, before private subjects.

This article addresses the fact that neuro-rights have the potential to have a special impact on certain human rights such as privacy, freedom of thought, mental integrity, the right not to be discriminated against, the right to a fair trial or the right to Not to incriminate itself, international human rights law makes no explicit reference to neuroscience. Unlike other biomedical developments and the expert evidence in the field of neuro-law that has already been the subject of normative efforts at the national and international level, it remains largely an unknown for international human rights law. However, the implications of neuroscience and neurotechnology for inherent characteristics of human beings call for a swift and flexible response of the law in this area to mental privacy.

This paper addresses the topic of university student representation, from the perspective of the Electoral and Administrative Law, with the help of relevant political categories. It especially studies the case of university student representation at the University of Costa Rica (UCR) in the context of the COVID-19 pandemic, the legal and political challenges, and the solutions offered by the pertinent student organisms. It offers a dual typology for student representation at the UCR. Furthermore, it explains the principle of continuity of the student representation, determining its content and limits, both in regular and extraordinary circumstances. The possible implications of these findings for the field of Electoral Law are also discussed.

Meredith Monk’s vocal music is defined by the presence of a disintegrated language —a language which has abandoned its normative nature— The voice, accompanied by a thorough gestural language, falls into a precultural, protolinguistic stratum. With his work, Monk —from a wide variety of aesthetics proposals: music, poetry, dramaturgy, audiovisual— gets into the area of Cultural Anthropology. In her compositions, the voice emerges always as music, but this music, first and foremost, seeks refuge in different human expressions as sighs, moans, screams or laughs. Throughout the following pages a synthetic view of Monk’s aesthetics from an epistemological basis will be shown, a basis where notions like game or mimesis play an axial role, as well as some others notions related to those, especially the dialectics between creation and decreation, or the concept musilanguage (as proposed by Robert N. Bellah, Steven Brown and Steven Mithen). This last term refers to music as basis of language.

In the Cuban cinema of the last decades appear continuously some spaces were carriers of revolutionary teleology in the recent past. These are old “schools in the countryside”, peasant villages founded in the heat of the revolutionary epic, and sugar and nuclear plants. In this article, based on the works El proyecto (Alonso, 2017), Despertando a Quan Tri (Pérez, 2005) and Melaza (Lechuga, 2012), it´s analyzed the way these spaces, which can be called residual, carry significant matter that shows the exhaustion of the teleological temporality of the Cuban Revolution. As a residue, the way in which a type of temporality marked by dead time unfolds in these spaces is studied in this article. This time, where living in dead time, as shown by the materials analized, implies a distance from all action and events, from history and narratives. This article concludes by specifying how, through a "writing between the lines" that also challenges the instituted language, these materials challenge the official narratives with which the History of the nation, of absolute State dominance, is told.
