A novel method for ECG signal outlier processing based on autoencoder neural networks is presented in the article. Typically, heartbeats with serious waveform distortions are treated as outliers and are skipped from the authentication pipeline. The main idea of the paper is to correct these waveform distortions rather them in order to provide the system with better statistical base. During the experiments, the optimum autoencoder architecture was selected. An open Physionet ECGID database was used to verify the proposed method. The (...) results of the studies were compared with previous studies that considered the correction of anomalies based on a statistical approach. On the one hand, the autoencoder shows slightly lower accuracy than the statistical method, but it greatly simplifies the construction of biometric identification systems, since it does not require precise tuning of hyperparameters.

This paper briefly reviews highlights from decades of debates in medicine, law, bioethics, psychology and social research about children’s and parents’ views and consent to medical treatment and research. There appears to have been a rise and later a fall in respect for children’s views, illustrated among many examples by a recent book on the zone of parental discretion, which is reviewed. A return to greater respect for children’s views and consent is advocated.

A continuoxis t- norm is a continuous map * from [0, 1]² into [0,1] such that is a commutative totally ordered monoid. Since the natural ordering on [0,1] is a complete lattice ordering, each continuous t-norm induces naturally a residuation → and becomes a commutative naturally ordered residuated monoid, also called a hoop. The variety of basic hoops is precisely the variety generated by all algebras, where * is a continuous t-norm. In this paper we investigate the structure of the (...) variety of basic hoops and some of its subvarieties. In particular we provide a complete description of the finite subdirectly irreducible basic hoops, and we show that the variety of basic hoops is generated as a quasivariety by its finite algebras. We extend these results to Hájek's BL-algebras, and we give an alternative proof of the fact that the variety of BL-algebras is generated by all algebras arising from continuous t-norms on [ 0,1] and their residua. The last part of the paper is devoted to the investigation of the subreducts of BL- algebras, of Gödel algebras and of product algebras. (shrink)

In this paper we introduce a poset of subvarieties of BL-algebras, whose completion is the entire lattice of subvarietes; we exhibit also a description of this poset in terms of finite sequences of functions on the natural numbers.

This paper explores the philosophical aspects of the "Great Introduction" of Abū Ma'šar, one of the great figures of Arabic astrology and an associate of al-Kindī, the great 9th century philosopher. I argue that the following points of philosophical interest may be found in this text: 1. Astrology is described as a "master science" along the lines proposed by Aristotle, i.e. it provides principles for lower sciences. Also he supplies arguments to ground astrology on methodological grounds, such as the use (...) of empirical evidence and testimony. 2. Abū Ma'šar broadly follows al-Kindī's explanation of how the stars influence the sublunary world, by heating the elements. This agrees with al-Kindī's work "On the Proximate Agent Cause of Generation and Corruption," and I identify some parallels between the two works. 3. Finally, Abū Ma'šarr considers whether human freedom is compatible with this causal account. He holds that human actions do fall under the class of the "possible" and not the "necessary," but only because for him the "possible" is what happens sometimes, not always. Thus he seems tacitly to hold that genuine choice is compatible with causal necessitation. (shrink)

K. J. Dover, in Greek Homosexuality, p. 125 n. 1, observes: ‘My interpretation ad loc., that drosos is Cowper's secretion, appearing when the boy's penis has been erected by titillation, is far-fetched, but no other interpretation so far seems to me to pay enough attention to the semantics of drosos or to explain why Right regards the beauty of “drosos and down” as incompatible with anointing below the navel’.

The role of emotions in ethics is often taken by philosophers and others as antithetical to rationality. On the most basic level (in undergraduate philosophy exams and elsewhere), stating an opinion in the form "I feel that p" can be a way of sidestepping the demand for reasons. But emotions can sometimes also be seen as supplying reasons for moral judgment to the extent that they involve evaluations--and a way of communicating them across different moral perspectives.

Stories from and about David's reign provide the background and justification for the accession of Solomon.

Critics generally have not warmed to Heroides 8. Jacobson opined that the poem is ‘not very successful’ and claimed that the lengthy argumentation is ‘rather boring, not to say sometimes silly and annoying’, while Palmer described it as ‘the feeblest and least poetical of all the Heroides’. However, scholars have largely neglected some typically Ovidian cleverness and complexity in kaleidoscopic play with character. Ovid's Hermione is Hermione, but she also takes on the guise of other mythological heroines, and she represents (...) a complete inversion of an earlier depiction of Hermione. All of this gives the poem a distinct intellectual appeal to supplement the emotional impact, with witty touches to ensure that the epistle is not mawkish. (shrink)

The managerial and personal approaches to Business Ethics are inadequate to address the systemic problems facing ethical reflection in Africa. It is argued that the ethical guidance position that takes the least advantaged individuals or groups in society as reference points is a more suitable ethical approach. The philosophical version of this egalitarian view as set out by John Rawls is then shortly explained, after which a few implications for Business Ethics in Africa are drawn.

New empirical evidence on the long-term effects of oestrogen treatment for tall adolescent girls has shown that the intended psychosocial benefit of the treatment may not have been realised. This paper describes recent trends in the prevalence of the treatment and the results of a large Australian cohort study evaluating girls assessed between 1959 and 1993 for excessive growth. The paper concludes that oestrogen treatment to prevent extreme tallness should belong to the past, not to the future.

RésuméLa psychanalyse se pose comme savoir quant à certains aspects de l'esprit humain et comme instrument pour y apporter des changements. II y a relativement peu de travaux consacrés à la structure de ce savoir ou aux modalités ?action de cet instrument.

We generalize the concept of a cooperative non-transferable utility game by introducing a socially structured game. In a socially structured game every coalition of players can organize themselves according to one or more internal organizations to generate payoffs. Each admissible internal organization on a coalition yields a set of payoffs attainable by the members of this coalition. The strengths of the players within an internal organization depend on the structure of the internal organization and are represented by an exogenously given (...) power vector. More powerful players have the power to take away payoffs of the less powerful players as long as those latter players are not able to guarantee their payoffs by forming a different internal organization within some coalition in which they have more power.We introduce the socially stable core as a solution concept that contains those payoffs that are both stable in an economic sense, i.e., belong to the core of the underlying cooperative game, and stable in a social sense, i.e., payoffs are sustained by a collection of internal organizations of coalitions for which power is distributed over all players in a balanced way. The socially stable core is a subset and therefore a refinement of the core. We show by means of examples that in many cases the socially stable core is a very small subset of the core.We will state conditions for which the socially stable core is non-empty. In order to derive this result, we formulate a new intersection theorem that generalizes the KKMS intersection theorem. We also discuss the relationship between social stability and the wellknown concept of balancedness for NTU-games, a sufficient condition for non-emptiness of the core. In particular we give an example of a socially structured game that satisfies social stability and therefore has a non-empty core, but whose induced NTU-game does not satisfy balancedness in the general sense of Billera.
