Published: August 2020

Background: This study aimed to discover the association between parameters of event-related potentials (ERPs) and categorization of images of visual scenes, both emotionally-charged and neutral, in carriers of different genotypes of the COMT, HTR2A, BDNF genes.

Methods: Electroencephalogram (EEG) and ERPs were recorded at 128 leads, with two ear referents. Images of different visual scenes were presented to the study participants sequentially on a monitor screen. The participants’ task was to examine these images and indicate what emotions (negative, neutral or positive) they elicit. Comparison of event-related potentials was carried out using unpaired Student t-test in EEGLAB toolbox.

Results: COMT. A stronger reaction, as reflected in the amplitude of the ERPs, in participants with the recessive homozygous Met/Met genotype was observed on latency around 200 ms to the stimuli, assessed as positive. Carriers of dominant homozygous Val/Val genotype had higher amplitude of 200 ms peak when assessed scene images as either neutral or negative in comparison to other genotypes. Participant with the Val/Met heterozygous genotype had higher amplitude of ERP that Met/Met group on same latency when assessed stimuli as negative.

HTR2A. Significant increase in negativity in the parietal-occipital regions revealed in the range of 350-420 ms in participants with the recessive homozygous A/A genotype when choosing any type of assessment, compared to carriers of the heterozygous genotype A/G and the dominant homozygous G/G genotype.

BDNF. Participants with Val/Val genotype categorized the visual images more thoroughly, as reflected in greater activation of the parietal-occipital zones and higher amplitude on ERP peak on 190 ms (negative assessment) and 160 ms (neutral assessment) then Val/Met carriers.

Conclusions: The COMT, HTR2A, BDNF gene different genotypes are associated with the process of categorizing emotionally charged and neutral visual scenes, and this relationship is reflected in the ERP parameters.
Independent accretion of TIM22 complex subunits in the animal and fungal lineages
Authors: Muñoz-Gómez Sergio A. , Snyder Shannon N. , Montoya Samantha J. , Wideman Jeremy G.
Published: August 2020

Background: The mitochondrial protein import complexes arose early in eukaryogenesis. Most of the components of the protein import pathways predate the last eukaryotic common ancestor. For example, the carrier-insertase TIM22 complex comprises the widely conserved Tim22 channel core. However, the auxiliary components of fungal and animal TIM22 complexes are exceptions to this ancient conservation.

Methods: Using comparative genomics and phylogenetic approaches, we identified precisely when each TIM22 accretion occurred.

Results: In animals, we demonstrate that Tim29 and Tim10b arose early in the holozoan lineage. Tim29 predates the metazoan lineage being present in the animal sister lineages, choanoflagellate and filastereans, whereas the erroneously named Tim10b arose from a duplication of Tim9 at the base of metazoans. In fungi, we show that Tim54 has representatives present in every holomycotan lineage including microsporidians and fonticulids, whereas Tim18 and Tim12 appeared much later in fungal evolution. Specifically, Tim18 and Tim12 arose from duplications of Sdh3 and Tim10, respectively, early in the Saccharomycotina. Surprisingly, we show that Tim54 is distantly related to AGK suggesting that AGK and Tim54 are extremely divergent orthologues and the origin of AGK/Tim54 interaction with Tim22 predates the divergence of animals and fungi.

Conclusions: We argue that the evolutionary history of the TIM22 complex is best understood as the neutral structural divergence of an otherwise strongly functionally conserved protein complex. This view suggests that many of the differences in structure/subunit composition of multi-protein complexes are non-adaptive. Instead, most of the phylogenetic variation of functionally conserved molecular machines, which have been under stable selective pressures for vast phylogenetic spans, such as the TIM22 complex, is most likely the outcome of the interplay of random genetic drift and mutation pressure.
Survey of the Heteroptera (Hemiptera) on pastures from Espírito Santo state, Brazil: new records, range extension, and notes of potential pests
Authors: Vélez Mayra , Coelho Lívia Aguiar , Martins David dos Santos , Ferreira Paulo Sergio Fiuza
Published: August 2020

Espírito Santo is a Brazilian state that has a wide variety of habitats, providing a high biological diversity of fauna and flora. However, few reports had been shown about the insect diversity of this region, especially of heteropterans insects that inhabit on pasture ecosystems. In the present study, forty-three species of Heteroptera belonging to thirteen families were collected on pastures on Espírito Santo state, Brazil: Alydidae (1 sp.), Berytidae (3 sp.), Blissidae (1 sp.), Coreidae (7 sp.), Miridae (16 sp.), Nabidae (1sp.), Pentatomidae (3 sp.), Pyrrhocoridae (1 sp.), Reduviidae (6 sp.), Rhopalidae (1 sp.), Rhyparochromidae (1sp.), Thaumastocoridae (1 sp.) and Tingidae (1 sp). Among the species; Cebrenis tenebrosa (Brailovsky, 1995) is recorded for the first time in Brazil. The range extension is also included for several heteropterans collected on the Espírito Santo state. The following species: Blissus aff. antillus (Leonard, 1968); Collaria oleosa (Distant, 1883); Oebalus ypsilongriseus (De Geer, 1773), and Trigonotylus tenuis (Reuter, 1893) were observed causing damages on pastures, therefore, in this study, we suggested those species as potential pastures pests. This study aims to increase the knowledge about the heteropterans and to show the presence of some pest species that may cause serious damage to pastures and consequently affect the economy of cattle breeders on the state.

Ao discorrer sobre o "cinema de mulheres" como um contracinema, propomos uma análise dos filmes Yvone Kane (2015), de Margarida Cardoso e Praça Paris (2017), de Lúcia Murat, duas coproduções Brasil-Portugal (no caso de Yvone Kane também com Moçambique) que põem em perspectiva o olhar da mulher branca sobre a “outra”, no caso, a mulher negra.  Percebemos em ambos os filmes, uma relação construída entre a subjetividade feminina das personagens em relação com a paisagem/território (seja em África ou no Brasil) que parece sublinhar, como apontamos em algumas cenas aqui apresentadas, uma  tensão racial entre a mulher branca e a mulher negra. Propomos um olhar analítico construído a partir da teoria e crítica feminista de cinema e do feminismo interseccional para analisar e discorrer acerca de ambos os filmes.

Abstract. Jayadi LZ, Susandarini R. 2020. Melissopalynological analysis of honey produced by two species of stingless bees in Lombok Island, Indonesia. Nusantara Bioscience 12: 97-108. Honey is a natural product with a variety of benefits that commonly used as food sweeteners, health supplements, and traditional medicine. There has been no comprehensive publication regarding the diversity of pollen contained in honey produced by stingless bee Tetragonula laeviceps and Heterotrogona itama from Lombok. This study aimed to reveal the diversity of pollen content in honey through melissopalynological analysis of honey samples produced by two species of stingless bees T. laeviceps and H. itama in Lombok Island. This melissopalynological study was performed on honey samples obtained from nine villages from nine sub-districts representing the three districts on Lombok Island. Pollen extraction from honey was carried out using standard methods for melissopalynological analysis. The diversity of pollen recovered from honey varied from 15 to 41 pollen types. Total number of plant species whose pollen was recovered from honey samples was 127 which consisted of 61 families. The occurrence of predominant pollen type in particular unifloral honey samples indicated their botanical origin and presumed geographical origin of honey. Results of this study are useful in confirming botanical origin of honey and generating information on plants potential as food source for sustainable beekeeping in Lombok Island.

Real-time, wide-field and high-quality single snapshot imaging of optical properties with profile correction using deep learning
Authors: Aguénounon Enagnon , Smith Jason T. , Al-Taher Mahdi , Diana Michele , Intes Xavier , Gioux Sylvain
Published: August 2020

The development of real-time, wide-field and quantitative diffuse optical imaging methods to visualize functional and structural biomarkers of living tissues is a pressing need for numerous clinical applications including image-guided surgery. In this context, Spatial Frequency Domain Imaging (SFDI) is an attractive method allowing for the fast estimation of optical properties using the Single Snapshot of Optical Properties (SSOP) approach. Herein, we present a novel implementation of SSOP based on a combination of deep learning network at the filtering stage and Graphics Processing Units (GPU) capable of simultaneous high visual quality image reconstruction, surface profile correction and accurate optical property (OP) extraction in real-time across large fields of view. In the most optimal implementation, the presented methodology demonstrates megapixel profile-corrected OP imaging with results comparable to that of profile-corrected SFDI, with a processing time of 18 ms and errors relative to SFDI method less than 10% in both profilometry and profile-corrected OPs. This novel processing framework lays the foundation for real-time multispectral quantitative diffuse optical imaging for surgical guidance and healthcare applications. All code and data used for this work is publicly available at www.healthphotonics.org under the resources tab.
Method for measuring the extinction ratios of optical pulse trains using optical gating
Authors: Arahira Shin , Murai Hitoshi , Sasaki Hironori
Published: August 2020

In this paper, we propose a method for measuring the extinction ratio (ER) of an optical pulse train with a very high ER. The proposed method can be implemented using a simple optical circuit consisting of an optical gate circuit and conventional optical powermeter. The ER is derived from a series of measurements of averaged gate output powers under several specific gate conditions. The proposed method was experimentally validated on an optical pulse train generated by cascaded

Noise-suppressing and lock-free optical interferometer for cold atom experiments
Authors: Ma Xiaoxiao , Zhang Xian , Huang Kaikai , Lu Xuanhui
Published: August 2020

A novel noise-suppressing and lock-free interferometer is proposed and experimentally demonstrated in the study of the quantum non-destructive (QND) interaction of cold atoms. A QND measurement based on far-off resonant dispersive probing is usually carried out by a Mach-Zehnder type interferometer. It is an experimental challenge in its own right to reduce the classical noise, such as acoustic noise, phase noise and amplitude noise of lasers, and to lock the interferometer at the white-light position that corresponds to a nearly zero path-length difference. Here, we report an interferometer with an inserted acousto-optic modulator (AOM). It is noise immune and lock-free in principle. The experiments show that the new interferometer is able to measure cold atoms for more than 30 minutes and reduce the phase noise by about 30 dB.

Published: August 2020

We analyze the multilayer structure of sunflower leaves from Terahertz data measured in the time-domain at a ps scale. Thin film reverse engineering techniques are applied to the Fourier amplitude of the reflected and transmitted signals in the frequency range f < 1.5 Terahertz (THz). Validation is first performed with success on etalon samples. The optimal structure of the leaf is found to be a 8-layer stack, in good agreement with microscopy investigations. Results may open the door to a complementary classification of leaves.
Stable-, period-N- and multiple-soliton regimes in a mode-locked fiber laser with inconsistently filtered central wavelengths
Authors: Wen Zengrun , Wang Kaile , Chen Haowei , Lu Baole , Bai Jintao
Published: August 2020

We systematically study the stable-, period-N- and multiple-soliton regimes in an Erbium-doped fiber laser effectively mode-locked by nonlinear polarization rotation technique. In the stable mode-locked regime, an invariant soliton with 497 fs pulse duration and 6.9 nm optical spectrum are obtained. With a larger pump power of 180 mW, the period-N state (in which the pulse intensity returns to its original value after N cavity-roundtrips) emerges, accompanied by sub-sideband generation on the first Kelly sideband and spectrum shift. Considering the inconsistent central wavelengths between gain and polarization-dependent isolator (PD-ISO) firstly, to our knowledge, the numerical results are in good agreement with the experiment and reveal the composite filtering of gain and PD-ISO takes major responsibility for spectrum shift, which causes group velocity offset simultaneously. Further study shows the continued increase of pump power can lead to the laser operating in the unstable multi-pulse state and the narrow spectral width contributes to stabilizing the multi-pulse state. Our work can promote the understanding of soliton dynamics and filtering in ultrafast fiber lasers.
Convergence of the iterative T-matrix method
Authors: Kahnert Michael , Rother Tom
Published: August 2020

Among the various methods for computing the T-matrix in electromagnetic and acoustic scattering problems is an iterative approach that has been shown to be particularly suited for particles with small-scale surface roughness. This method is based on an implicit T-matrix equation. However, the convergence properties of this method are not well understood. Here, a sufficient condition for the convergence of the iterative T-matrix algorithm is derived by applying the Banach fixed point theorem. The usefulness of the criterion is illustrated by applying it to predicting, as well as to systematically improving the convergence of the iterative method.
Training data generation and validation for a neural network-based equalizer
Authors: Liao Tao , Xue Lei , Huang Luyao , Hu Weisheng , Yi Lilin
Published: August 2020

The neural network (NN) has been widely used as a promising technique in fiber optical communication owing to its powerful learning capabilities. The NN-based equalizer is qualified to mitigate mixed linear and nonlinear impairments, providing better performance than conventional algorithms. Many demonstrations employ a traditional pseudo-random bit sequence (PRBS) as the training and test data. However, it has been revealed that the NN can learn the generation rules of the PRBS during training, degrading the equalization performance. In this work, to address this problem, we propose a combination strategy to construct a strong random sequence that will not be learned by the NN or other advanced algorithms. The simulation and experimental results based on data over an additive white Gaussian noise channel and a real intensity modulation and direct detection system validate the effectiveness of the proposed scheme.
Tuning temperature gradients in subwavelength plasmonic nanocones with tilted illumination
Authors: Cunha Joao , Guo Tian-Long , Alabastri Alessandro , Proietti Zaccaria Remo
Published: August 2020

Inducing and controlling temperature gradients in illuminated subwavelength plasmonic structures is a challenging task. Here, we present a strategy to remotely induce and tune temperature gradients in a subwavelength metallic nanocone by adjusting the angle of incidence of linearly polarized continuous-wave illumination. We demonstrate, through rigorous three-dimensional numerical simulations, that properly tilting the incident illumination angle can increase or decrease the photoinduced temperature gradients within the nanostructure. We analyze the apex-base photoinduced temperature gradient for different illumination directions, resembling typical illumination schemes utilized in surface or tip-enhanced Raman spectroscopy.

Neste estudo, investigamos o comportamento do motorista em uma rodovia considerando a percepção sobre a qualidade de serviço em função das condições de tráfego, usando um simulador de direção e um sistema de rastreamento ocular.  O simulador de direção permite criar ambientes de direção diferentes, muito semelhantes aos cenários de direção da vida real. Desenvolvemos três cenários diferentes, com densidades de tráfego baseadas em diferentes níveis de serviço, e também preparamos um questionário para avaliar a percepção do usuário. Os dados do questionário, do simulador de direção e do sistema de rastreamento ocular de vinte participantes foram incluídos em nosso banco de dados. Realizamos análise estatística usando testes não paramétricos (testes de Kruskal-Wallis e Tukey) e medimos os coeficientes de correlação de Pearson entre as variáveis. Nessa abordagem preliminar, os motoristas conseguiram diferenciar os cenários e determinar as pontuações para cada nível de serviço apresentado. Esses resultados sugerem que os simuladores de direção têm um potencial considerável para a avaliação da percepção da qualidade de serviço (QoS).
Returning to the heart of teaching: Social pedagogy as phenomenological pedagogy
Authors: Schoone Adrian
Published: August 2020

In many alternative education centres in New Zealand tutors are charged with educating students disenfranchised from their mainstream secondary schools. However, these tutors do not hold teaching qualifications. Rather, they draw their pedagogical approaches from life experiences, cultural knowledge, vocational and relational skills, and passion to work with young people. Tutors’ heartfelt ways of engaging with young people has a transformative impact on many of the students’ life-courses. This article poetically represents key approaches central to tutor practice. From observations and research interview transcripts, found poems were created from the everyday language of eight tutors. The poems represent phenomenological insights into tutors’ lived experiences, and reveal that tutors intentionally place students at the centre of their practice. The article positions tutor pedagogy within a social pedagogical field, while also considering social pedagogy as a phenomenological pedagogy that brings us to the very heart of teaching.
Play therapy insights into everyday social pedagogical practice in residential child care
Authors: Engen Mie , Bjerre Line Søberg , Jensen Mogens
Published: August 2020

Psychotherapy and social pedagogical care, help and support in relation to children placed in out-of-home care are typically perceived as two separate forms of practice. In its typical form, psychotherapy is pictured as a meeting between therapist and client in a ‘therapeutic space’ separated out from daily life and activities, while social pedagogical care, help, and support is carried out in close proximity to everyday life in what is regarded as the person’s home. This article analyses an alternative relationship and way of collaborating between psychotherapy – more specifically play therapy – and everyday social pedagogical practice in residential care for children with severe emotional and behavioural problems. This is done by drawing on an empirical case study of the relationship between everyday practice and expertise of social pedagogical practice and play therapy in a children’s home in Denmark. Meeting the needs of children who have been severely neglected and/or abused is challenging in different ways, and it requires highly developed relational, emotional, and reflective skills. The authors argue that play therapy has a particular potential in foregrounding and developing core social pedagogical knowledge and skills. When designed and carried out as an integrated part of everyday social pedagogical practice, play therapy can support practitioners in integrating a reflective and conscious approach to understanding and meeting the children’s emotional and relational needs with the ability to create and enter into ‘playful encounters’ with the children that challenges one-sided and taken-for-granted power relationships, practices and norms.
MARITAL RAPE SEBAGAI ALASAN PERCERAIAN DALAM KAJIAN MAQÂSHID SYARI’AH
Authors: Darussamin Zikri , Armansyah Armansyah
Published: August 2020

According to Act No. 23 of 2004, marital rape is mentioned as a variant of domestic violence. However, it still considered by some people as a reasonable action and often legitimized by religious arguments. In turn, this diversity of perception generates the contradiction between the implemented positive law and Islamic law. Through a comparative approach, this paper attempts to find the perspective of Islamic law on this critical issue by way of collecting as many Qur’ānic verses and prophetic hadith as possible, as well as the developed argumentations around it, and analyzing them accordingly in light of maqāṣid al-syarī’ah. At the end, this paper discovers that the practice of marital rape is unlawful according to Islamic law. Therefore, it can serve as a reason for divorce.Undang-Undang Nomor 23 Tahun 2004 tentang Penghapusan Kekerasan dalam Rumah Tangga (PKDRT) mengategorikan marital rape sebagai salah satu varian tindak kejahatan kekerasan dalam rumah tangga. Namun dalam tataran tertentu, marital rape masih dinilai sebagai tindakan wajar dan tak jarang dilegitimasi dengan dalil-dalil agama. Perbedaan persepsi ini telah menimbulkan kontradiksi antara hukum positif yang berlaku dengan hukum Islam yang dipahami masyarakat. Secara komparatif, tulisan ini berusaha menemukan perpektif hukum Islam dalam memandang persoalan marital rape dengan cara menghimpun sebanyak mungkin ayat Alqurān dan hadis serta argumen-argumen di sekitarnya, dan menganalisisnya dalam konteks maqāṣid al-syarī’ah. Di akhir penelitian ditemukan bahwa marital rape merupakan sesuatu yang bertentangan dengan syariat Islam. Oleh karena itu dapat dijadikan sebagai alasan perceraian.

Se presenta una investigación en donde se analizan los procesos que aplica un grupo de estudiantes de Bachillerato durante la resolución de problemas matemáticos, en torno al estudio de las funciones cuadráticas. La teoría que sustentó el trabajo fue el aprendizaje significativo desde la perspectiva Ausubeliana. La metodología de esta investigación fue de tipo descriptivo-cuantitativo, enmarcada dentro de un diseño no-experimental de tipo transeccional descriptivo. Los datos se recabaron de una muestra de 38 estudiantes que fue tomada mediante una técnica de muestreo no-probabilístico, y a la cual se le aplicó dos instrumentos: un cuestionario y una entrevista semi-estructurada. El cuestionario constó de cuatro situaciones problema cuyas soluciones podían encontrarse haciendo uso de las funciones cuadráticas, mientras la entrevista estuvo conformada por trece preguntas semiestructuradas que permitieron complementar la información recabada en el cuestionario. Los resultados evidenciaron que los estudiantes tienden a adquirir un proceso de aprendizaje mecánico y memorístico, dejando a un lado el proceso de reflexión que les permita diseñar una estrategia adecuada para resolver un problema relacionado con las funciones. En conclusión, consideramos que es necesario que los docentes apliquen estrategias de enseñanza-aprendizaje que estimulen la recurrencia a los conocimientos previos del estudiante con el fin de obtener un aprendizaje significativo.
What students can learn from Fibonacci´s error in solving “The lion in the pit” problem
Authors: Slisko Josip
Published: August 2020

This initial study presents the results of the classroom implementation of a learning sequence derived from Fibonacci’s error in solving ‘The lion in the pit’ problem. The study was carried out with 35 physics students in a general first-semester course ‘Development of complex-thinking skills’. The learning sequence was implemented as a paper-and-pencil activity in personal and group modes. The most important results are the following: (a) Students were able to provide an acceptable procedure about how Fibonacci might get the wrong answer, (b) students can argue why that answer is wrong, (c) some students’ solutions presented good conceptual and procedural clarity, frequently missed in historic literature, and (d) students grasped the importance of knowing about errors made by famous mathematicians in two connected aspects: mathematics is a human activity prone to errors and, consequently, fear of errors shouldn’t be an obstacle in learning of school mathematics.

Independensi Lembaga Kejaksaan sebagai Legal Structure didalam Sistem Peradilan Pidana (Criminal Justice System) di Indonesia
Authors: Mufrohim Ook , Herawati Ratna
Published: August 2020

Lembaga Kejaksaan menurut fungsinya berada pada posisi yang sentral dan sangat strategis di dalam proses penegakan  hukum secara independen. Lembaga kejaksaan sangat riskan untuk mendapatkan intervensi dari pihak pemerintah ataupun pihak lain sehingga tuntutan hukum menjadi tidak  berdasarkan atas peraturan perundang-undangan yang berlaku dan tidak makmsimal. Tulisan ini membahas independensi kejaksaan sebagai bagian sistem peradilan pidana berdasarkan telaah legal structure. Penelitian ini menggunakan Metode Kualitatif dengan Pendekatan Yuridis Normatif. Penelitian ini menunjukkan bahwa kejaksaan merupakan bagian dari struktur hukum yang menjalankan substansi hukum, memiliki  tugas dan kewenangan untuk melakukan penuntutan dan kewenangan lain yang ditentukan menurut undang-undang.  Jaksa Agung juga memiliki kewengan diponering, namun  pelaksanaan diponering seringkali mendapatkan intervensi dari  penguasa. Intervensi bisa berimplikasi pada hasil penuntutan lembaga kejaksaan sebagai bagian system peradilan pidana kurang berkeadilan dan berkemanusiaan, serta kurang terciptanya tertib hukum dan tegaknya supremasi hukum.
The Political Economy of Private Law
Authors: Thiemann Matthias
Published: August 2020

Katharina Pistor’s book The code of capital – how the law creates wealth and inequality (Pistor, K. (2019). The code of capital – How the law creates wealth and inequality. Princeton: Princeton University Press) is an original and insightful intervention in the quest to understand both the rising inequality of the last 40 years, as well as the inner dynamics of capitalism, a social formation that has ruled in western societies for about 200 years now. Pistor shares many of the convictions of the publications in the journal Accounting, Economics and Law, such as the dangers to democracy inherent in the corporate form (Robé, J. P. (2011). The legal structure of the firm. Accounting, Economics and Law, 1(1). https://doi.org/10.2202/2152-2820.1001; Strasser, K., & Blumberg, P. (2011). Legal form and economic substance of enterprise groups: Implications for legal policy. Accounting, Economics and Law, 1(1). https://doi.org/10.2202/2152-2820.1000), the fact that firms and corporate form need to be distinguished (Y. Biondi, A. Canziani, & T. Kirat (Eds), (2007). The firm as an entity: Implications for economics, accounting and law. New York and London: Routledge) and that shareholders do not own corporations, but just their shares, it is only appropriate to discuss and present it to the wider audience of the journal, pointing to its fundamental insights and potential for follow-up research. The title of the book and its set-up evoke both Luhmann’s system theory with its penchant for binary code as well as Marx’s capital (Marx, K. (1955[1867]). Das Kapital. Berlin: Dietz Verlag, Vol. 1). Combining the coding of social systems and their relentless dynamic in innovating and generating new forms by recursively referring to established elements (Luhmann, N. (1984). Soziale Systeme. Frankfurt am Main: Suhrkamp Verlag; Luhmann, N. (1995). Das Recht der Gesellschaft. Frankfurt am Main: Suhrkamp Verlag) with Marx’s focus on the structuring effects capital has on society is making this a very inspiring book, which at the same time evokes many follow-up questions.
An Intrinsic Characterization of Five Points in a CAT(0) Space
Authors: Toyoda Tetsu
Published: August 2020

Gromov (2001) and Sturm (2003) proved that any four points in a CAT(0) space satisfy a certain family of inequalities. We call those inequalities the ⊠-inequalities, following the notation used by Gromov. In this paper, we prove that a metric space X containing at most five points admits an isometric embedding into a CAT(0) space if and only if any four points in X satisfy the ⊠-inequalities. To prove this, we introduce a new family of necessary conditions for a metric space to admit an isometric embedding into a CAT(0) space by modifying and generalizing Gromov’s cycle conditions. Furthermore, we prove that if a metric space satisfies all those necessary conditions, then it admits an isometric embedding into a CAT(0) space. This work presents a new approach to characterizing those metric spaces that admit an isometric embedding into a CAT(0) space.
The Analogies of Justice and Health inRepublic IV
Authors: Torres Jorge
Published: August 2020

This paper provides a new interpretation of Plato’s account of justice as psychic health in Republic IV. It argues that what has traditionally been considered to be one single analogy is actually a more complex line of reasoning that contains various medical analogies. These medical analogies are not only different in number but also in kind. I discuss each of them separately, while providing a response to various objections.
Well-posedness of problem with parameter for an integro-differential equation
Authors: Assanova Anar T. , Bakirova Elmira A. , Vassilina Gulmira K.
Published: August 2020

A problem with parameter for an
integro-differential equation is approximated by a
problem with parameter for a loaded differential equation.
The well-posedness of a problem with parameter for the
integro-differential equation is established in the terms of the well-posedness of a problem with parameter for the loaded differential equation. A mutual relationship between the qualitative properties of original
and approximate problems is obtained, and the estimates for
differences between their solutions are set.
A new general solution to the
loaded differential equation with parameter is presented, and its properties are described. The problem with parameter for the loaded differential equation
is reduced to a system of linear algebraic equations
with respect to the arbitrary vectors of a general solution
introduced. The system’s coefficients and right-hand sides are computed
by solving the Cauchy problems for ordinary differential
equations.
Verbal Serialization in Biblical Aramaic
Authors: Andrason Alexander , Koo Bonsam
Published: August 2020

The present paper discusses the issue of Serial Verb Constructions (SVCs) in Biblical Aramaic within the dynamic grammaticalization-based model of verbal serialization – a recent modification of a prototype-driven approach to SVCs used in linguistic typology. Having analyzed the entire corpus of Biblical Aramaic, the authors conclude the following: (a) verbal serialization constitutes an integral part of the verbal system of Biblical Aramaic; (b) pre-canonical SVCs are more common that canonical SVCs, and no cases of post-canonicity are attested; (c) Biblical Aramaic is a semi-advanced serializing language. Overall, the research corroborates the tendency of Semitic languages to gradually increase their serializing profile; a tendency that is often – albeit not without exception – correlated with the languages’ relative chronology.
Non-lactate strong ion difference and cardiovascular, cancer and all-cause mortality
Authors: Verma Ashish , Qayyum Rehan
Published: August 2020

Objectives

Non-lactate strong ion difference (SID) has been shown to be associated with predictors of mortality in intensive care unit. However, the existence of any association between non-lactate SID (nlSID) and all cause, cardiovascular and cancer mortality has not been explored before in community dwelling US adults.

Methods

In a nationally representative cross-sectional survey of the US non-institutionalized population, all adult participants (≥20 years of age) using National Health and Nutrition Examination Survey data (1999–2010) combined with National Death Index for mortality status through December 2011. Cox proportional hazard models were built to estimate the hazard ratios for cardiovascular, cancer, and all-cause mortality for each unit increase in non-lactate SID. The models were adjusted for demographic and confounder variables

Results

In the study population the mean (SD) age was 49.6 (18.4) years. Of the study population, 31,475 (91.5%) were alive and 2,893 (8.4%) died during the mean (SD) follow-up period of 5.5 (3.5) years. In univariate regression model using nlSID as continuous variable, we found 2% (unadjusted hazard ratio, HR=1.02; 95% CI, 1.004–1.05) increase in all-cause but not in cardiovascular and cancer mortality (HR=1.03; 95% CI, 0.99–1.08, HR=1.01; 95% CI, 0.97–1.06). After adjusting for potential confounders, we found 7% (adjusted HR=1.07; 95% CI, 1.04–1.10), 5% (HR=1.05; 95% CI, 1.00–1.11) and 7% (HR=1.07; 95% CI, 1.02–1.12) increase in all-cause, cardiovascular, and cancer mortality.

Conclusions

A high nlSID is associated with an increase in cardiovascular, cancer and all-cause mortality and may be a prognostic indicator of mortality in general adult population. These findings may provide a point of reference for further studies.
A numerical external pitting damage prediction method of buried pipelines

Published: August 2020

The work introduces a numerical external damage prediction method for buried pipelines. The external pitting initiation and corrosion rate of oil or gas pipelines are affected by pipeline age, physicochemical properties of soils and cathodic protection performance as well as coating conditions. Before developing the damage prediction model, the influencing factors were weighed by grey relational analysis, and then the relationship among the pitting depth and the influencing factors of external corrosion was established for corrosion damage prediction through artificial neural network (ANN). Subsequently, the established ANN was applied to predict corrosion damage and corrosion rate for some selected cases, and the neural network prediction model was analyzed and compared to another corrosion rate prediction models. Through the analysis and comparison, a few opinions were proposed on the external corrosion damage prediction and pipeline integrity management.
Artefacts as Signs, Signs as Artefacts
Authors: Borrelli Giorgio
Published: August 2020

The category of “artefact” has been analyzed by different semiotic theories and methods. Starting from the Marxian theory of the dialectical relation betweenproductionanduse(orconsumption), Ferruccio Rossi-Landi (1921–1985) maintained the possibility of considering every “artefact” – oruse-value– as a crossroads betweenmaterialandlinguisticproduction, i.e., as a crossroads between labor and language. This paper proposes a comparison – and a dialogue – between Rossi-Landi’s materialistic sign-theory and other semiotic approaches. From such a perspective, the concept of “artefact” could be considered as an analytical starting point for the study of further social and economic meaning-making processes.
Zur Logik der Sprache: Hölderlin und Hegel
Authors: Kreuzer Johann
Published: August 2020

This paper “on the logics of language” discusses the fundamental role which the reality of language plays in the thinking of Hölderlin as well as in Hegel. Common to both is the emphasis on the ‘Wirklichkeit der Sprache’ – in the double sense of this phrase: the reality language is, and the reality language has. At the same time there is, of course, the great difference that for Hegel the logic of language fulfils itself in the ‘work of the concept(s)’ [“Arbeit des Begriffs”], while for Hölderlin it is fulfilled in forms of poetry or in the broader sense of poetic work. The paper explores the origins, conceptual basics and consequences of the dialectic between moving ‘from language to logics’ in Hegel and moving ‘from logics to language’ in Hölderlin. The main works of Hegel considered here are Die Phänomenologie des Geistes, Wissenschaft der Logik and some parts of the Enzyklopädie (1830); from Hölderlin the focus is on the theoretical fragments Seyn, Urtheil, …, Das untergehende Vaterland … and Wenn der Dichter einmal des Geistes mächtig ist …. One central issue treated by exploring the discussion between Hegel and Hölderlin is their respective concepts of memory and its development. Reflecting on the connection between the power of imagination and the necessity of forms of utterance is the other. The primary aim of the paper is to explain the relevance that Hölderlin’s poetic work has in philosophical perspective – a relevance which can be explained in relation to Hegel.
Multi-temporal survey of diaphragm wall with terrestrial laser scanning method
Authors: Zaczek-Peplinska Janina , Kowalska Maria Elżbieta , Łapiński Sławomir , Grzyb Michał
Published: August 2020

The development of measurement technologies allows for acquiring various data. The Terrestrial Laser Scanning (TLS) technology is frequently combined with classic geodetic measurements – tacheometry or levelling. This article presents a process of the diaphragm wall monitoring during excavation supported with a top-down method. The construction technology applied required proper planning and performance of measurements in difficult construction site conditions in the city centre. TLS allowed for limiting works at daytime and performing monitoring during the night break in works at the construction site as well as limiting the impact of the subsoil process vibrations on the values of displacements and deformations determined. The authors present a comparison of the results of displacement and deformation measurements with a terrestrial laser scanning and tacheometric measurement method. The possibilities of using the data acquired, among others, for the indication of filtration areas, spatial surface deformation analyses and assessment of the wall execution compliance with the design are presented. The analyses carried out show that the TLS may be used in the investment process from the very beginning, being a component of the Building Information Modelling (BIM).
