Pathological tremor is a common but highly complex movement disorder, affecting ~5% of population older than 65 years. Different methodologies have been proposed for its quantification. Nevertheless, the discrimination between Parkinson’s disease tremor and essential tremor remains a daunting clinical challenge, greatly impacting patient treatment and basic research. Here, we propose and compare several movement-based and electromyography-based tremor quantification metrics. For the latter, we identified individual motor unit discharge patterns from high-density surface electromyograms and characterized the neural drive to a (...) single muscle and how it relates to other affected muscles in 27 Parkinson’s disease and 27 essential tremor patients. We also computed several metrics from the literature. The most discriminative metrics were the symmetry of the neural drive to muscles, motor unit synchronization, and the mean log power of the tremor harmonics in movement recordings. Noteworthily, the first two most discriminative metrics were proposed in this study. We then used decision tree modelling to find the most discriminative combinations of individual metrics, which increased the accuracy of tremor type discrimination to 94%. In summary, the proposed neural drive-based metrics were the most accurate at discriminating and characterizing the two most common pathological tremor types. (shrink)

The study examines the end or purpose of the acts of the virtue of religion within Thomas Aquinas' ethics of human action. What is the end of religious worship? Is it God, or is it the worshippers themselves? On the one hand, one would presume that God cannot be the end of religion because, from the perspective of Classical Theism (of which Aquinas is a main proponent), God cannot benefit from the activity of creatures. But on the other hand, if (...) the worshipper is the end of religious acts, would not worship be a self-centered or an egotistic act? The standard Thomistic account of the problem, first laid out by Cajetan and later adopted by countless followers, is that God is the finis cuius ("the aim toward which") of the acts of the virtue of religion, whereas the religious worshipper is the finis quo (the beneficiary) of the acts. I argue that this solution, which is based on a single text of Aquinas (ST II-II.81.7c), is insufficient. After examining Aquinas' theory of action (the doctrine of object, end, and circumstances presented in ST I-II.18), I show how the object of a particular human act can be interpreted as the finis operis (the end of the agent's act). Utilizing this principle of the identity between the object and the finis operis, I argue that the finis operis of religion can be summed up as a threefold sequence of ends: the honor, reverence, and glory of God. As a result, the ultimate beneficiary of acts of religious worship is neither God nor the individual worshipper, but rather the totality of the universe, encapsulated by Aquinas in his notion of divine "glory," that is, the extrinsic manifestation of God's intrinsic goodness within the universe.

In the first author's thesis [10], a sequential language, LRT, for real number computation is investigated. That thesis includes a proof that all polynomials are programmable, but that work comes short of giving a complete characterization of the expressive power of the language even for first-order functions. The technical problem is that LRT is non-deterministic. So a natural characterization of its expressive power should be in terms of relations rather than in terms of functions. In [2], Brattka examines a formalization (...) of recursive relations in the style of Kleene's recursive functions on the natural numbers. This paper is an expanded version of [13] which establishes the expressive power of LRTp, a variant of LRT, in terms of Brattka's recursive relations. Because Brattka already did the work of establishing the precise connection between his recursive relations and Type 2 Theory of Effectivity, we thus obtain a complete characterization of first-order definability in LRTp.

In lieu of an abstract, here is a brief excerpt of the content:The Happiness of “Those Who Lack the Use of Reason”Miguel J. RomeroHuman beings would have been created uselessly and in vain were they unable to attain happiness, as would be the case with anything that cannot attain its ultimate end.(De Malo, q. 5, a. 1, ad 1)A STUDY OF “those who lack the use of reason” in the thought and spirit of St. Thomas Aquinas has much to offer (...) the patient reader. We better understand what it means to be a rational animal, the image of triune God, when we investigate why, exactly, “mindless persons” (amentes) are not exceptions or even outliers in Aquinas’s account of the creaturely dignity and perfectibility of the human being.Aquinas remarks with some regularity on persons afflicted with the condition amentia, which is variously and inconsistently interpreted (in translation) as “imbeciles,” “fools,” “madmen,” “lunatics,” “the demented,” or “the insane.” The amentes are persons who lack the use of reason in a profound and debilitating way; and, as I will show, the fact that we are sometimes found in this state informs Aquinas’s analysis of human nature and, in particular, Aquinas’s teaching on the good wrought by Christ for the members of his body. Our guiding question is this: Thinking with Aquinas, how do we account for the natural and supernatural happiness of those of us who lack the use of reason?My purpose in this article is to explore what Aquinas has to say about the happiness of persons who are baptized and [End Page 49] confirmed by the Church, and who have what neuro-psychologists would describe as a profound cognitive impairment. The question is particularly striking when we recall that, for Aquinas, the distinguishing aptitude of the human being (proper to our intellectual nature and coordinate with our creaturely perfection) is the operation of an incorruptible intellectual capacity—a capacity, however, that is only reduced from potentiality to act when the corruptible “internal sense organ” is disposed to receive, in terms of health and circumstance, a coordinated sense impression of material species. Thus, a further question emerges: According to Aquinas, what is the perfective effect of grace in this life upon the nature of a person who completely lacks the use of reason due to an organic corruption or disorder of the ‘internal sense organ’?The discussion is divided into five parts. I begin (part I) by locating those who “lack the use of reason” within the theological infrastructure of Aquinas’s moral psychology and I identify the main problematic. With respect to that problematic, the principal conceptual resources provided by Aquinas are then outlined and two challenges are identified (part II).The first challenge is methodological, concerning the speculative import of the sacramental life of the Church. Francisco de Vitoria’s Relectio de eo ad quod tenetur homo veniens ad usum rationis (1534) highlights for us (part III) a constellation of judgments relevant to interpreting Aquinas on these themes, in particular, Aquinas’s formulation of prerational intellectual acts vis-à-vis the participation and membership of “mindless persons” in the sacramental life of the Body of Christ.The second challenge is to show the continuity between Aquinas’s account of the human being and his practical remarks on those who lack the use of reason. Specifically, given the various ways that, and degrees to which, the human being can lack the use of reason, I trace (part IV) Aquinas’s analysis of the power and operation of intellect, focusing on the intellectual acts which can be impaired and, concurrently, the intellectual acts which cannot be impaired in a living human being. Aquinas’s remarks on those latter acts not only reflect the [End Page 50] significance of the doctrine of the image of God in his account of human nature, but, even more, they shed light on the prosthesis of sacramental grace in his understanding of the properly human happiness capacitated and purposed in all whom God has called in Christ—a call to discipleship and devotion that includes those of us who have a profound, lifelong cognitive impairment (Rom 8:28; 9:11; Eph 1:3-14; II Tim 1:8-11).I conclude...

We discuss the concepts of Weyl and Riemann frames in the context of metric theories of gravity and state the fact that they are completely equivalent as far as geodesic motion is concerned. We apply this result to conformally flat spacetimes and show that a new picture arises when a Riemannian spacetime is taken by means of geometrical gauge transformations into a Minkowskian flat spacetime. We find out that in the Weyl frame gravity is described by a scalar field. We (...) give some examples of how conformally flat spacetime configurations look when viewed from the standpoint of a Weyl frame. We show that in the non-relativistic and weak field regime the Weyl scalar field may be identified with the Newtonian gravitational potential. We suggest an equation for the scalar field by varying the Einstein-Hilbert action restricted to the class of conformally-flat spacetimes. We revisit Einstein and Fokker’s interpretation of Nordström scalar gravity theory and draw an analogy between this approach and the Weyl gauge formalism. We briefly take a look at two-dimensional gravity as viewed in the Weyl frame and address the question of quantizing a conformally flat spacetime by going to the Weyl frame. (shrink)

Aquinas has been accused of being a sexist for making the following four claims about woman: (1) woman is a deficient male; (2) woman was created only for the purpose of procreation; (3) woman is inferior to man; (4) woman must submit to man. Some scholars, notably Michael Nolan, have attempted to defend Thomas, and a few have even gone so far as calling him a feminist. The aim of this paper is to show that Aquinas did hold these four (...) claims throughout his career, and to show in what sense he held them, thus revealing how well-founded the accusations remain, given the assumptions of feminism. Finally, the authors propose that any future attempt to exonerate Aquinas from the charge of sexism must grapple with the question of how these claims are compatible with a gender-equality view.

The oft-rehearsed, seldom-contested story of Aquinas’s account of sacra doctrina has him holding that revealed theology counts as a demonstrative science, along Aristotelian lines, because it is subaltern to God’s self-knowledge. This paper seeks to question this assessment of the matter by comparing Aquinas’s view to that of another great Aristotelian commentator, Averroes, who holds the contrary position, insofar as he considered religious discourse to be dialectical, and not scientific, in nature. The paper argues that, although both of these thinkers (...) strive to present faithfully Aristotelian solutions to the problem of the epistemological status of religious discourse and in both accounts religious discourse somehow ends up being less than something naturally scientific, ultimately their approaches have widely divergent starting points and foundations that lead to distinctively different approaches and conclusions.

Counting models for a two conjunctive formula $F$, a problem known as $\sharp $2Sat, is a classic $\sharp $P complete problem. Given a 2-CF $F$ as input, its constraint graph $G$ is built. If $G$ is acyclic, then $\sharp $2Sat can be computed efficiently. In this paper, we address the case when $G$ has cycles. When $G$ is cyclic, we propose a decomposition on the constraint graph $G$ that allows the computation of $\sharp $2Sat in incremental way. Let $T$ be (...) a cactus graph of $G$ containing a maximal number of independent cycles, and let $\overline{T}=-E)$ be a subset of frond edges from $G$. The clauses in $\overline{T}$ are ordered in connected components $\{K_1, \ldots, K_r\}$. Each $, i=1,\ldots,r$ is a knot of the graph. The arrangement of the clauses of $\overline{T}$ allows the decomposition of $G$ in knots and provides a way of computing $\sharp $2Sat in an incremental way. Our procedure has a bottom-up orientation for the computation of $\sharp $2Sat. It begins with $F_0 = T$. In each iteration of the procedure, a new clause $C_i \in \overline{T}$ is considered in order to form $F_i = $ and then to compute $\sharp $2Sat$$ based on the computation of $\sharp $2Sat$$.

Although the influence of social support in health is a widely acknowledged factor, there is a significant gap in the understanding of its role on cognition. The purpose of this systematic review was, therefore, to determine the state-of-the-art on the literature testing the association between social support and cognition. Using six databases, we identified 22 articles published between 1999 and 2019 involving an empirical quantitative focus which meet the inclusion criteria. Data extraction was performed following PRISMA recommendations. To summarize the (...) extracted data, we used a narrative synthesis approach. Despite limitations, there is overall preliminary evidence of a relevant positive association between social support and cognition. Our results demonstrate there is enough information for an outbreak of experimental research in the area and an expansion of this body of knowledge. We argue that the present evidence lays the foundations for a more comprehensive theoretical model, one that corresponds with the complexity of the topic and possibly considers models derived from social interaction and active inference theories.

The introduction of a new analytical method, due fundamentally to François Viète and René Descartes and the later dissemination of their works, resulted in a profound change in the way of thinking and doing mathematics. This change, known as process of algebrization, occurred during the seventeenth and early eighteenth centuries and led to a great transformation in mathematics. Among many other consequences, this process gave rise to the treatment of the results in the classic treatises with the new analytical method, (...) which allowed new visions of such treatises and the obtaining of new results. Among those treatises is the Arithmetic of Diophantus of Alexandria which was written, using the new algebraic language, by the French mathematician Jacques Ozanam, who in addition to profusely increasing the original problems of Diophantus, solved them in a general way, thus obtaining many geometric consequences. The work is handwritten, it has never been published, it has been lost for almost 300 years, and the known references show its importance. We will show that Ozanam’s manuscript was quoted as an important work on several occasions by others mathematicians of the time, among whom G. W. Leibniz stands out. Once the manuscript has been located, our aim in this article is to show and analyze this work of Ozanam, its content, its notation and its structure and how, through the new algebraic method, he not only solved and expanded the questions proposed by Diophantus, but also introduced a connection between the algebraic solutions and what he called geometric determinations by obtaining loci from the solutions.

RESUMEN Se analiza la relación entre la escritura y la presencia en la obra de Maurice Blanchot, se delimita el fundamento textual de la presencia en el orden de la literatura y se toman como referentes teóricos los conceptos de "espacio literario" y "pensamiento del afuera" de Michel Foucault. Si bien el propósito de examinar dicha relación es deconstruir el vínculo entre presencia y lenguaje, Blanchot conduce a considerar esa continuidad en términos de una presencia nunca completa ni devenida que (...) se conserva como una discontinuidad, una promesa y una ausencia que deben preservarse. ABSTRACT The article analyzes the relation between writing and presence in the work of Maurice Blanchot and defines the textual grounds of presence in the order of literature, using Michel Foucault's concepts of "literary space" and the "thought of the outside" as theoretical referents. While the objective of examining that relation is to deconstruct the link between presence and language, Blanchot leads us to consider that continuity in terms of a never complete or fulfilled presence that remains as discontinuity, as promise and absence that must be preserved.

Building on evidence for embodied representations, we investigated whether Spanish spatial terms map onto the NEAR/FAR perceptual division of space. Using a long horizontal display, we measured congruency effects during the processing of spatial terms presented in NEAR or FAR space. Across three experiments, we manipulated the task demands in order to investigate the role of endogenous attention in linguistic and perceptual space mapping. We predicted congruency effects only when spatial properties were relevant for the task but not when attention (...) was allocated to other features. Results showed faster responses for words presented in Near-space in all experiments. Consistent with our hypothesis, congruency effects were observed only when a reaching estimate was requested. Our results add important evidence for the role of top-down processing in congruency effects from embodied representations of spatial terms. (shrink)

El libro de Herbert Marcuse Entre fenomenología y marxismo. Escritos filosóficos 1928-1933 viene a satisfacer la demanda de los lectores del autor de América latina, y de habla hispana en general, de tener una edición definitiva de sus trabajos de juventud. Marcuse nos había llegado como uno de los principales representantes del llamado marxismo heterodoxo del siglo XX. A su nombre habíamos asociado principalmente el proyecto de la Escuela de Frankfurt y la constitución de una teoría crítica de la sociedad; (...) el auge de los movimientos sociales de protesta de la generación del 68, la fundación de una nueva izquierda internacional, así como el análisis teórico sobre la dominación de las necesidades y deseos en las sociedades industriales avanzadas; los intentos por pensar la clase revolucionaria más allá del proletariado industrial y una original propuesta de lectura de la estructura históricosocial desarrollada por Marx en conjunto con la histórico-subjetiva desarrollada por Freud. Obras como Razón y revolución y El marxismo soviético, sentaron las bases para una nueva interpretación de la dialéctica de Hegel y de Marx y la denuncia de las formas esclerotizadas del marxismo en las directrices ideológicas de la Unión Soviética.

El libro de Alex Ibarra, Filosofía chilena. La tradición analítica en el periodo de la institucionalización de la filosofía, plantea la discusión sobre las líneas filosóficas, demostrando la existencia de cierta tradición analítica en Chile. A partir de allí, reflexionamos en torno a los procesos de constitución del campo de la filosofía en Chile como una historia atravesada por la necesidad de préstamos y cruces que impiden una delimitación clara de sus límites, lo que tornaría necesaria la atención a ciertas (...) políticas de la lectura que el libro soslaya. La productividad de la filosofía producida en Chile surgiría gracias -y no pese- a su inscripción en sus tiempos y espacios, a partir de recepciones cuya ausencia de retraso no impide el gesto de cierto re-trazo de lo leído. Alex Ibarra's exposition in his book Filosofía chilena. La tradición analítica en el periodo de la institucionalización de la filosofía, places the discussion on the philosophical traditions, showing the existence of a certain kind of analytical tradition in Chile. From there, we expose the processes of constitution of the field in Chile as a history crossed by the need of importations and intersections that contest the clear delimitation of its boundaries, what makes necessary the attention of the politics of readings that the book avoid. The productivity of the philosophic production in Chile, arises thanks to -but not in spite of- its inscription in its age/times and spaces, coming from its receptions and its differences. (shrink)
