A classification method for binary predictors
combining similarity measures and mixture
models
Authors: Sylla Seydou N. , Girard Stéphane , Diongue Abdou Ka , Diallo Aldiouma , Sokhna Cheikh 
Published: May 2020

Abstract
In this paper, a new supervised classification method dedicated to binary predictors is proposed. Its
originality is to combine a model-based classification rule with similarity measures thanks to the introduction
of new family of exponential kernels. Some links are established between existing similarity measures
when applied to binary predictors. A new family of measures is also introduced to unify some of the existing
literature. The performance of the new classification method is illustrated on two real datasets (verbal
autopsy data and handwritten digit data) using 76 similarity measures.
Circolazione e vendita della Syngraphe di Anassagora (Plat. Apol. 26d-e)
Authors: Caroli Menico 
Published: May 2020

Abstract
The price ("a drachma at most'') at which a copy of Anaxagoras' Σνγγραφή is sold, in Plat. Apol. 26d-e, is problematic in its real meaning. The difficulty of fixing an overall picture is determined by the fragmentation of the arguments in dozens of commentaries ad loc. First of all, it is necessary to take into account variables (essential for a correct interpretation of this price), such as the cost of the papyrus, especially in epigraphical evidence relating to different moments of Greek economy, and alternative forms of κτῆσις βιβλίων.
Esencia, definición y la tesis de identidad en Aristóteles, Metaphysica Z 4-6
Authors: Mié Fabián 
Published: May 2020

Abstract
To clarify Aristotle’s “Identity Thesis” in Metaphysics Z 6, according to which each strictly definable item must be identical to its own essence (1031a15-16, 1032a4- 6), I show that it is a simple corollary of some “logical” theorems drawn from the Organon, which have a direct impact on Z 4’s explanation that identity is based on the possession of essence. As I claim, Z 6’s innovation consists of a clarification about substance as that which - because of having essence - can fulfill the identity- condition. Therefore, Z 6’s argument targets principally “non-Identity” as a consequence of Platonic separation. Further, I argue against the commonly held view that the Identity Thesis stands on the hylomorphism of Z’s later chapters.

On-line moisture content estimation of saw dust via machine vision
Authors: Valta Art , Ruusunen Mika , Leiviskä Kauko 
Published: May 2020

Abstract
The effect of moisture content and feasibility of its estimation in granular material was investigated via machine vision. The test scheme consisted of saw dust samples derived from Norway spruce with moisture content adjusted to three distinct levels. The effect of moisture when present as ice or liquid water was compared. The experimental procedure consisted of pouring the saw dust under video camera recording. The equipment setup consisted of a vibrator feeder and custom-built pouring frame. Still images were extracted with fixed sample time from the recording done during the pouring procedure. From the extracted frames the dynamic behavior of cone profile was investigated via statistical means. It was observed that 2nd standardized moment correlated with moisture content, phase of water and their interaction. Furthermore, 4th standardized moment correlated with moisture content and phase. The 3rd moment was inspected qualitatively from which it was observed that wet samples exhibited tendency to build mass accumulation sites with increasing moisture content. Samples where water was present as ice this was observed in a very small scale with all moisture content values. Corroborated by optical microscopy, these correlations were deduced to be due to liquid bridging in the bulk. Moisture content when present as ice was, however, observed to have a drastic effect on the overall cone shape. Based on these findings, a machine vision application could be feasible way to estimate moisture content on-line in thawed saw dust by using statistical parameters in classification decision making. This would enable cost-effective on-line monitoring of moisture content and a control circuit to be designed.

Multi-temporal analysis of an agricultural landscapetransformation and abandonment (Lubietová, Central Slovakia)
Authors: Masný Matej , Zaušková Lubica 
Published: May 2020

AbstractSocio-political changes in the countries of Easternand Central Europe in the era of socialism had significant effects on agricultural landscape. Collectivisation(1950 - 1970) lost almost all of traditional agricultural landscapes.On the other hand, the phenomenon of agriculturalabandonment started to be significant after 1989. Inthe model area (part of The Polana Biosphere Reserve)these two processes that formed the agricultural landscapestructure were analysed. The analyses were carriedout using orthophotos that represented the landscapestructure in 1949, 1986 and 2006. It was found that almostcomplete extinction of the traditional agricultural landscaperepresented by a mosaic of narrow fields and permanentgrasslands occurred during the period. At the sametime, increasing trend of abandonment processes was observed.In 2006, non-forestwoody vegetation covered 48%of agricultural land.Natural reforestation as the final stageof agricultural abandonment extended to 46% on the formeragricultural land in 2006. Abandonment processeswere the most significant already in the period of socialistagriculture. To describe the changes, landscape metricssuch as Number of patches (NP), Mean patch size (MPS),Patch size standard deviation (PSSD) and Mean shape index(MSI) were used.
A new statistical approach to the geochemical systematics of Italian alkaline igneous rocks
Authors: Ambrosio Francesco Antonio 
Published: May 2020

Abstract
The ultra-alkaline rocks have exotic features that frustrated many attempts to group them in a single classification diagram. A consistent classification would be very useful to define a possible consanguinity, an argument that feed a living debate. This paper investigates the petrologic characteristics of the Cenozoic Italian ultra-alkaline rock-suite using -Rank Entropy Anentropy (RHA) and Principal Component Analysis (PCA)-. The RHA formula is the succession of component’s symbols arranged according to the diminishing of their elemental content in the analysis (whole rock composition). Other two parameters considered are an expression of the anentropy and entropy of the system. The PCA allows the definition of new latent variables based on geochemical compositions through linear combinations of the major oxides. Using both statistical methods was possible to create discrete groups of rock-types, associated by genetic relationship. The groups plotted in the Mg-Ca-Al ternary diagram depicts two main evolutionary arrays. We interpret the chemical variance in term of a general magmatic processes based on immiscibility and crystal fractionation. A comparison with similar association worldwide give a more general prospective to the magmato-tectonic assignment of these rocks, which is highly controversial in Italy.
Bitcoin’s Identity Crisis and the Prospect of Trustless Money
Authors: Zamaria Alain 
Published: May 2020

Abstract
Whether it is legally treated as a digital property, a commodity or a security, bitcoin’s identity crisis is mainly caused by its contradictions as a trustless monetary project. The paper argues that bitcoin’s trustlessness is a confusing concept that accounts for its legal and monetary troubles. As explicated by monetary sociologists and economists, money is based on a complex trust architecture. By questioning the interplay between code, trust and law in the monetary realm, the paper aims to enlighten the philosophy of bitcoin’s monetary project, the current trends, and some potential developments for bitcoin and distributed ledger technologies.

Core 1 O-N-acetylgalactosamine (O-GalNAc) glycosylation in the human cell nucleus
Authors: Cejas Romina B. , Garay Yohana C. , de la Fuente Sofia , Lardone Ricardo D. , Irazoqui Fernando J. 
Published: May 2020

Abstract
Glycosylation is a very frequent post-translational modification in proteins, and the initiation of O-N-acetylgalactosamine (O-GalNAc) glycosylation has been recently described on relevant nuclear proteins. Here we evaluated the nuclear incorporation of a second sugar residue in the biosynthesis pathway of O-GalNAc glycans to yield the terminal core 1 glycan (C1G, Galβ3GalNAcαSer/Thr). Using confocal microscopy, enzymatic assay, affinity chromatography, and mass spectrometry, we analyzed intact cells, purified nuclei and soluble nucleoplasms to identify the essential factors for C1G biosynthesis in the cell nucleus. The enzyme C1GalT1 responsible for C1G synthesis was detected inside the nucleus, while catalytic activity of C1Gal-transferase was present in nucleoplasm and purified nuclei. In addition, C1G were detected in the nucleus inside of intact cells, and nuclear proteins exposing C1G were also identified. These evidences represent the first demonstration of core 1 O-GalNAc glycosylation of proteins in the human cell nucleus. These findings reveal a novel post-translational modification on nuclear proteins, with relevant repercussion in epigenetic and chemical biology areas.
Tragedies of the Capitalocene
Authors: Arons Wendy 
Published: May 2020

AbstractThe idea of the “Anthropocene” is rapidly gaining currency as an ecocritical lens through which to view theater and performance. But as a lens for critical analysis, the concept of the “Anthropocene” is problematic, primarily because it fails to differentiate among humans, many of whom are in conflict precisely because the benefits and costs of the “Age of Man” have been distributed unevenly. Neo-Marxist critics take such conflicts into fuller account in their argument that a better nomenclature and concept for our epoch is the “Capitalocene,” a term that captures the fact that our ecological crises have been precipitated not by humans in some undifferentiated and generalized way, but more specifically by the global spread of capitalism and its socio-economic-ecological injustices. These are also conflicts at the heart of many plays, both historical and recent. This essay offers an overview of a number of works that might productively be categorized as “Tragedies of the Capitalocene,” insofar as they dramatize stories that trace the dynamics of “Capitalocene” exploitation of both human and nonhuman resources. Plays considered include Cherríe Moraga’s Heroes and Saints (1992), Rahul Varma’s Bhopal (2001), Kia Corthron’s A Cool Dip in the Barren Saharan Crick (2010), Annabel Soutar’s Seeds (2012), Robert Schenkkan’s The Kentucky Cycle (1991), and Colleen Murphy’s The Breathing Hole (2017).

Abstract
A new series of homobivalent Dimebon analogs, bis-γ-carbolines with alkylene, phenylenedialkylene, and triazole-containing spacers, was synthesized. Doubling the γ-carboline pharmacophore increased inhibitory potency against acetylcholinesterase (AChE) compared with Dimebon, while keeping Dimebon’s anti-butyrylcholinesterase activity; therefore, leading to inversion of selectivity. Molecular docking revealed the reasons for the increased anti-AChE activity and ability to block AChE-induced aggregation of β-amyloid for bis-γ-carbolines, which became double-site inhibitors of AChE. Conjugates with ditriazole-containing spacers were the most active antioxidants in both the ABTS-test and prevention of lipid peroxidation in brain homogenates without inhibiting the mitochondrial permeability transition (MPT). Conjugates with alkylene (4a–d), phenylenedialkylene (4e), and monotriazole (8) spacers were less active as antioxidants but prevented induction of the MPT and increased the calcium retention capacity of mitochondria. Lead compound 4e showed neuroprotective potential in a cellular calcium overload model of neurodegeneration. Computational studies showed that all the bis-γ-carbolines were expected to have high values for intestinal absorption and very good blood-brain barrier permeability along with good drug-likeness. Overall, the results showed that new homobivalent Dimebon analogs exhibit an expanded spectrum of biological activity and improved pharmacological properties, making them promising candidates for further research and optimization as multitarget agents for Alzheimer’s disease treatment.
TouchYou: A wearable touch sensor and stimulator for using our own body as a remote sex interface
Authors: Gomes Leonardo Mariano , Wu Rita 
Published: May 2020

AbstractIn this article, we present TouchYou, a pair of wearable interfaces that enable
affective touch interactions with people at long-distance. Through a touch-sensitive
interface, which works by touch, pressure and capacitance, the body becomes the own
input for stimulating the other body, which has a stimulation interface that enables
the feeling of being touched. The person receives an electrical muscle stimulation,
thermal and mechanical stimulation that react depending on the touch sensed by the
first interface. By using the TouchYou, people can stimulate each other, using their
own body, not only for sexual relations at a distance but for the production of
affection and another way of feeling. We discuss the importance of the touch for
human relationships, the current state of the art in haptic interfaces and how the
technology can be used for the affection remote transmission. We present the design
process of the TouchYou sensitive and stimulation interfaces, with a contribution of
a method for developing custom touch sensors, we explore usage scenarios for the
technology, including sex toys and sex robots and we present the concept of using the
body as a remote sex interface.
Why Digital-Era Political Marketing is Not the Death Knell for Democracy: On the Importance of Placing Political Microtargeting in the Context of Party Competition
Authors: König Pascal D. 
Published: May 2020

AbstractPolitical microtargeting has been depicted as a severe danger for democratic representation. It is said to fragment the electorate, help manipulate voters, and make politics overall less responsive and inclusive. However, the present paper aims to show why these are not general consequences to be expected from political microtargeting. It argues that a greater consideration needs to be given to context for a more differentiated understanding of microtargeting. The paper adds to existing research by situating political microtargeting within research on party politics. First, it shows that based on core assumptions about party competition and the strategic incentives it involves, one would not expect that microtargeting practices undermine democratic representation. Major constraints resulting from party competition hardly allow parties to be less responsive and inclusive when employing microtargeting. Second, the presence of such constraints furthermore depends on the larger political and institutional context that shapes the intensity of competition.
Rurality and Party System Fragmentation in the Nigerian Presidential Elections of the Fourth Republic
Authors: Nwankwo Cletus Famous 
Published: May 2020

AbstractThis paper examines the effect of rurality on party system fragmentation in the Nigerian presidential elections of the fourth republic. The findings show that party system fragmentation (PSF) has been characteristically low in the Nigerian presidential elections and rurality does not significantly predict party system fragmentation. Rurality has a negative effect on PSF in all the elections studied except the 2003 election but only significant in the 2011 poll. Thus, the paper cast doubt on previous studies that indicate that striking rural-urban differences manifest in party system fragmentation in African elections and attribute it to previous studies’ measure of rurality. The paper argues that the use of a composite measure of rurality instead of singular measures of rurality might provide better analysis that helps us understand the effect of rurality on party systems. Also, it argues that in the study of the rural-urban difference in voting behaviour or political behaviours more broadly, data should be aggregated based on cities and non-city areas because cities have distinctive urban characters compared with non-city places. Analyses done on states or constituencies level may not reveal the rural-urban difference because states and constituencies usually have a mix of rural and urban population and other characteristics.

COVID-19: TINJAUAN MAQASID AL-SHARIAH TERHADAP PENANGGUHAN PELAKSANAAN IBADAH SHALAT DI TEMPAT IBADAH (Hifdz al-Nafs Lebih Utama Dari Hifdz al-Din?)
Authors: Qotadah Hudzaifah Achmad 
Published: May 2020

Abstrak Penyebaran virus berbahaya bernama Covid-19 yang tengah terjadi saat ini telah menciptakan berbagai polemik dan persoalan di tengah kehidupan masyarakat baik persoalan ekonomi, sosial, politik maupun agama khususnya. Misalnya saja, polemik mengenai penangguhan atau larangan mengenai ibadah shalat juma’at ataupun berjamaah di masjid yang mana persoalan tersebut melahirkan berbagai reaksi pro-kontra dari kalangan masyarakat. Masyarakat yang pro menganggap bahwa hal tersebut sebagai bentuk pencegahan dan antisipasi penyebaran virus korona atau Covid-19 yang tengah mewabah. Adapun masyarakat yang kontra terhadap penangguhan tersebut memandang bahwa hifdz al-din (memelihara agama seperti ibadah shalat) lebih utama dari hifdz al-nafs (memelihara jiwa atau nyawa). Oleh sebab itu, tujuan utama penelitian ini ialah untuk menjelaskan tinjauan Maqasid al-Shariah terhadap pembatasan, penangguhan, serta larangan pelaksanaan ibadah shalat Jum’at maupun lainnya semasa terjadi sebuah wabah. Metode yang digunakan penulis dalam penelitian ini ialah dengan menggunakan metode kualitatif penuh serta data dokumentasi yang terkait dengan topik kajian penelitian ini, kemudian dianalisis secara deskriptif.Kata-kata kunci: COVID-19, Maqasid al-Shariah, Shalat, Hifdz al-Din, Hifdz al-Nafs. AbstractThe spread of a deadly epidemic known as Covid-19 has indeed caused several polemics such as economic, social, political and religious issues in particular. For instance, the conflicts regarding ban congregational prayers and also mass gatherings amid coronavirus or Covid-19 pandemic have led to various responses pros and cons amongst the society. The pro assumes that it is indeed a way of preventing as well as anticipate the transmission of Covid-19. Unlike those who disagree with that kind of postponement, they presume that hifdz al-Din (protection of religion) is much more important than hifdz al-Nafs (protection of life). Furthermore, the key main objective of this research is to describe the postponement or cancelation of Friday prayers and mass gatherings due to coronavirus pandemic based on comprehensive study of maqasid al-shariah. In this research, the researcher uses full qualitative method and documentation related to the topic of this research, which then will be analyze descriptively.Keywords: COVID-19, Maqasid al-Shariah, Salat, Hifdz al-Din, Hifdz al-Nafs.
