Object agreement and locality in Hungarian
Authors: Szécsényi Krisztina , Szécsényi Tibor
Published: March 2020

The paper claims that the two types of object agreement in Hungarian, definiteness agreement and the special
lak-agreement form used for the combination of first person singular subject and second person object arguments, are
the result of different syntactic operations. The argumentation is based on the different distribution of the two agreement
types. To diagnose the nature of the conditions for agreement we use infinitival embedded clauses, at times with multiple
embedded constructions. Six different patterns are discussed showing sensitivity to locality. Definiteness agreement turns out
to be more restricted than lak-agreement. While the condition for definiteness agreement is the availability of a
position where accusative case can be checked, we claim that no such condition holds for lak-agreement.
(Non-)exhaustivity in focus partitioning across languages
Authors: Zimmermann Malte , De Veaugh-Geiss Joseph P. , Tönnis Swantje , Onea Edgar
Published: March 2020

We present novel experimental evidence on the availability and the status of exhaustivity inferences with focus partitioning in
German, English, and Hungarian. Results suggest that German and English focus-background clefts and Hungarian focus share
important properties, (É. Kiss 1998, 1999; Szabolcsi 1994; Percus
1997; Onea & Beaver 2009). Those constructions are anaphoric
devices triggering an existence presupposition. EXH-inferences are not obligatory in such constructions in English, German, or
Hungarian, against some previous literature (Percus 1997; Büring & Križ 2013; É. Kiss 1998), but in line with
pragmatic analyses of EXH-inferences in clefts (Horn 1981, 2016; Pollard & Yasavul 2016). The
cross-linguistic differences in the distribution of EXH-inferences are attributed to properties of the Hungarian number
marking system.
Attitudes toward Portuguese in Uruguay in the nineteenth century
Authors: Bertolotti Virginia , Coll Magdalena
Published: March 2020

The Uruguay-Brazil border has been a porous geographical area since colonial times, giving rise to intense contact between Portuguese and Spanish, further fostered by a shared economic and demographic foundation. Here we analyze attitudes toward border Portuguese and that language in general in the Uruguayan territory during the Luso-Brazilian military occupation (1816–1828) and later in the century and identify two parallel realities: a predominant neutral attitude toward Portuguese, as the language was not an object of evaluation; and the existence of negative attitudes toward Portuguese promoted by the authorities in Montevideo. In absence of diachronic attitude studies, we developed an ad hoc methodology to document and describe this dual reality, drawing on legislative documents, government archives, press, and literary pieces.
Language use, language attitudes and identity in Curaçao
Authors: Kester Ellen-Petra
Published: March 2020

This chapter presents the results of 471 questionnaires distributed in Curaçao in order to investigate patterns of language use, language attitudes and identity among participants belonging to different age groups and with different parental birthplaces. The results pointed out that the speech community of Curaçao is rather homogeneous. Papiamentu, the mother tongue of the majority of the population, is widely used and attitudes toward Papiamentu and Curaçaoan identity are overall very positive. A statistical analysis of the results indicated that the use of Papiamentu by informants with foreign-born parents correlated with positive attitudes toward the language and toward Curaçaoan identity. These findings provide important insights for language policy and planning, particularly in relation to the education system.

Giving meaning to illness and death
Authors: Domínguez Martí , Sapiña Lucía
Published: March 2020

In recent years, adolescents and young adults
(ayas) with cancer and survivors of childhood cancer
have started to organize as a collective in Europe. In this context,
associations have included in their websites stories by young people
diagnosed with cancer or who have gone through the disease. In this
study, four of these websites (two in Spanish and two in English) are
analyzed to obtain information on how ayas approach the
subject of death in their stories. From the total of 128 studied
stories, explicit references to death appear in 30. Discourse
analysis will show us how ayas give meaning to the end of
their own and their friends’ life.
Religion, collusion, and “fighting”
Authors: Clemente Ignasi
Published: March 2020

This chapter is based on an ethnographic study of
communicative practices surrounding the death of a five-year-old
pediatric cancer patient in a hospital in Catalonia (Spain). In the
present case study, I highlight the significant co-occurring
variation in how cancer and death are discussed or avoided within
the same sociocultural. Specifically, I focus on three ways of
talking about cancer and death: (1) using religious imagery, (2)
co-creating the optimistic and hopeful collusion that everything is
going well, and (3) using “let’s keep fighting” language.
Rhetoric of death in clinical case reports and clinical
tales
Authors: Kotátková Adéla
Published: March 2020

Death is a taboo in Western civilization. Even
healthcare fields, which are strongly familiar with the end
of life, cannot avoid the tendency to soften the impact
caused by talking or writing about death. Like anyone else,
healthcare professionals who publish clinical case reports
(ccr) tend to use euphemisms. They also have the option
to use a technical lexicon that could be perceived as a range of
euphemistic expressions. In this chapter we review the place of
death in this professional genre. We also compare several aspects of
the rhetoric of death in ccr and clinical tales. The
latter, though frequently written by medical authors, are intended
for a non-specialized public and have a literary communicative
purpose.

Published: March 2020

The oleaginous yeast Rhodosporodium toruloides is receiving widespread attention as an alternative energy source for biofuels due to its unicellular nature, high growth rate and because it can be fermented on a large-scale. In this study, R. toruloides was cultured under both light and dark conditions in order to understand the light response involved in lipid and carotenoid biosynthesis. Our results from phenotype and gene expression analysis showed that R. toruloides responded to light by producing darker pigmentation with an associated increase in carotenoid production. Whilst there was no observable difference in lipid production, slight changes in the fatty acid composition were recorded. Furthermore, a two-step response was found in three genes (GGPSI, CAR1, and CAR2) under light conditions and the expression of the gene encoding the photoreceptor CRY1 was similarly affected.

Site selective adsorption of the spin crossover complex Fe(phen)2(NCS) on Au(111)
Authors: Beniwal Sumit , Sarkar Suchetana , Baier Felix , Weber Birgit , Dowben Peter A , Enders Axel
Published: March 2020

The iron(II) spin crossover complex Fe(1,10-phenanthroline)2(NCS)2, dubbed Fe-phen, has been studied with scanning tunneling microscopy, after adsorption on the ‘herringbone’ reconstructed surface of Au(111) for sub-monolayer coverages. The Fe-phen molecules attach, through their NCS-groups, to the Au atoms of the fcc domains of the reconstructed surface only, thereby lifting the herringbone reconstruction. The molecules stack to form 1D chains, which run along the Au[110] directions. Neighboring Fe-phen molecules are separated by approximately 2.65 nm, corresponding to 9 atomic spacings in this direction. The molecular axis, defined by the two phenanthroline groups, is aligned perpendicular to the chain axis, along the Au

direction, thereby bridging over 5 atomic spacings, in this direction. Experimental evidence suggests that the molecular spins are locked in a mixed state in the sub-monolayer regime at temperatures between 100 K and 300 K.
A simple, reliable and robust reinforcement method for the fabrication of (RE)–Ba–Cu–O bulk superconductors
Authors: Namburi Devendra K , Huang Kaiyuan , Lau Wayne , Shi Yunhua , Palmer Kysen G , Dennis Anthony R , Cardwell David A , Durrell John H
Published: March 2020

Bulk high temperature superconductors (HTS) based on the rare-earth barium cuprates [(RE)BCO] have the potential to be applied in a variety of engineering and technological applications such as trapped field magnets, rotating electrical machines, magnetic bearings and flywheel energy storage systems. The key materials figure of merit for most practical applications of bulk superconductors is simply the product of the maximum current density that can be supported, which correlates directly with the maximum achievable trapped magnetic field, and the physical length scale over which the current flows. Unfortunately, however, bulk (RE)BCO superconductors exhibit relatively poor mechanical properties due to their inherent ceramic nature. Consequently, the performance of these materials as trapped field magnets is limited significantly by their tensile strength, rather than critical current and size, given that the relatively large Lorentz forces produced in the generation of large magnetic fields can lead to catastrophic mechanical failure. In the present work, we describe a simple, but effective and reliable reinforcement methodology to enhance the mechanical properties of (RE)BCO bulk superconductors by incorporating hybrid SiC fibres consisting of a tungsten core with SiC cladding within the bulk microstructure. An improvement in tensile strength by up to 40% has been achieved via this process and, significantly, without compromising the superconducting performance of the bulk material.

Published: March 2020

Thermoacoustic is one of the technological sciences that utilizes thermodynamics and acoustic waves. The thermoacoustic device is divided into two, namely the thermoacoustic engine that converts heat energy into acoustic waves, and the heat pump used to pump heat from low temperature reservoirs to higher temperatures by utilizing acoustic waves. This study examines the numerically of the effect of radius stack on the efficiency and the value of low heating temperature of thermoacoustic engine. This study use the fortran application with two codes, the first coding to get the value of stability limit, one of that is a low heating temperature. And to get the efficiency value, use the second code, which one of the result is the coding to get the value of coefficient of performance. As a result, the highest level of efficiency is when the stack radius has a size of 0.07 mm which reaches 57% while the lowest heating temperature value is reached when the stack has a radius of 0.12 mm which is 124 °C. So from this result, it can be seen that there is an influence of radius stack on the efficiency and low heating temperature of the thermoacoustic engine.

Published: March 2020

In writing, students may have numerous strategies in organizing their ideas. The technology invention can be utilized as a means in enhancing student’s writing project. One of them is Evernote application as one of the most popular software for keeping and organizing information. This article is aimed at 1) revealing the application of teaching writing by using Evernote as graphic organizer; 2) finding the strengths of using Evernote; and 3) finding the challenges of using Evernote. This article uses library research as a method to gather the information. From the result of study, writing in Evernote is as simple as using a word processor. We need to have a Google account first to sign up to this application. When we have already signed up, we can create “new note.” Once we have finished, give it a title to make it easy to find later and enter texts. The strengths are that Evernote can create different forms including words, audio, and images. Another study also shows that the group of students given graphic organizer can show more rational thought than students without graphic organizer. It also has more interesting display by adding various colors. The challenges for this application are that it requires constant internet connection. It also should be provided by sufficient hardware. Therefore, it is suggested that the institution could provide sufficient means to meet this need. It is because despite of its challenges, this application is beneficial for students and teachers for becoming technology literate in learning process.

Published: March 2020

Electrical energy sources are currently declining so that renewable energy is environmentally friendly as an alternative energy source. This paper aims to test the charging of a hybrid system based on the prototype of a hybrid solar power plant and wind/wind energy as an alternative energy source. The method of carrying out the activity is carried out by charging the system to the accumulator when the wind speed is capable of turning the turbine and filling the accumulator and at the wind speed that is not able to fill the accumulator with a hybrid system. This research was conducted at Akarena Beach Makassar in the dry season. The results showed that testing of hybrid generators with parallel solar panels totalling 4 pieces @ 50 Watt peak (Wp) to 200 Watt peak (Wp) was able to charge 4 accumulators connected parallel @ 18 Ah or 72 Ah for ± 10 hours in sunny conditions with a charging current of 7.39 Amperes at wind speeds of 1-3 m / s and at wind speeds of 5-7 m / s the magnitude of the charging current reaches 8.02 Amperes at 15:00 to 17:00, thus, the charging time becomes faster after the turbine works with wind speeds above 5 m / sec.

The SDGs 2030 Agenda is a global development agreement to end poverty, reduce inequality and protect the environment. One of the objectives of the SDGs that will be achieved is ensuring the availability and management of sustainable clean water and sanitation for all. In order to achieve this goal, this research was conducted to measure the sustainability of the provision of clean water treatment plants (IPAB) in Soppeng District. The sustainability analysis conducted by multidimensional scaling approach that is also called Rap-IPABSoppeng approach (rapid appraisal IPAB Soppeng) which is a development of the RAPFISH method (rapid assessment techniques for fisheries). The results of the multidimensional analysis of the sustainability of Rap-IPABSoppeng for the provision of clean water treatment plants in Soppeng Regency based on existing conditions, obtained a sustainability index value of 45.64% and included in a less sustainable status. This sustainability index value is obtained based on an assessment of 48 attributes from five dimensions of sustainability, namely environmental, economic, social, infrastructure and technology, and legal and institutional dimensions. In the environmental dimension it has an index value of 36.54% with a less sustainable status, the index value in the economic dimension is 52.27% with a fairly sustainable status, the index value in the social dimension is 47.35% with a less sustainable status, the index value on the dimensions of infrastructure and technology is 36.03% with a less sustainable status, and the status is quite sustainable in the legal and institutional dimensions with an index of 51.87%. In order for the sustainability index value in the future to continue to increase until it reaches a sustainable status, then it is necessary to make improvements to 18 sensitive attributes that affect the five dimensions of sustainability.

This paper intends to design an Ultra-Wideband (UWB) antenna for future Internet of Things (IoT) applications for off-body Wireless Body Area Networks (WBAN) communication. An antenna based on the Y-shaped patch fed using co-planar waveguide (CPW) line, with a full ground plane is designed. It is implemented on two different substrates, namely a 5mm thick Rogers RO4350B and a 5-mm-thick felt textile. Parametric analysis of antenna is performed by changing its critical dimensions and monitoring parameters such as gain, bandwidth, efficiency, radiation pattern when using both substrates. Besides that, the bending effects towards reflection coefficient and radiation patterns are also studied. The final patch size with the Y-shaped slot is 36 × 40 mm2 for both substrates. The antenna is capable of providing coverage for the bands from 8 to 10 GHz. Finally, the antenna designed on RO4350B substrate outperforms the antenna designed on felt by about four times in terms of bandwidth, with 3.3 GHz (7.7–11 GHz).
Adaptive parameter selection for weighted-TV image reconstruction problems
Authors: Calatroni Luca , Lanza Alessandro , Pragliola Monica , Sgallari Fiorella
Published: March 2020

We propose an efficient estimation technique for the automatic selection of locally-adaptive Total Variation regularisation parameters based on an hybrid strategy which combines a local maximum-likelihood approach estimating space-variant image scales with a global discrepancy principle related to noise statistics. We verify the effectiveness of the proposed approach solving some exemplar image reconstruction problems and show its outperformance in comparison to state-of-the-art parameter estimation strategies, the former weighting locally the fit with the data [4], the latter relying on a bilevel learning paradigm [8, 9].
Sequential Sparse Blind Source Separation for Non-Linear Mixtures
Authors: Kervazo C , Bobin J
Published: March 2020

Linear Blind Source Separation (BSS) has known a tremendous success in fields ranging from biomedical imaging to astrophysics. In this work, we however propose to depart from the usual linear setting and tackle the case in which the sources are mixed by an unknown non-linear function. We propose to use a sequential decomposition of the data enabling its approximation by a linear-by-part function. Beyond separating the sources, the introduced StackedAMCA can further empirically learn in some settings an approximation of the inverse of the unknown non-linear mixing, enabling to reconstruct the sources despite a severely ill- posed problem. The quality of the method is demonstrated experimentally, and a comparison is performed with state-of-the art non-linear BSS algorithms.

A learning-based inversion strategy for passive wireless detection of crowds
Authors: Polo Alessandro , Abdul Hannan Mohammad , Gottardi Giorgio , Viani Federico
Published: March 2020

Passive indoor localization is an emerging technology for the detection and tracking of transceiver-free entities using wireless infrastructures. Customized wireless sensors are often used for the acquisition of suitable wireless signals. In this work, neither hardware customization nor dedicated deployment are introduced. The wireless signal transmitted by standard Wi-Fi access points is processed to solve an inverse problem for the real-time detection of crowds. Towards this end. a wavelet decomposition of the acquired data is combined with a learning- by-example (LBE) strategy in order to learn the complex relation between crowd presence and signal perturbations. Experimental results show the capabilities of the proposed solution in detecting people within a real Wi-Fi enabled test site. The obtained performance points out that a standard Wi-Fi network can be profitably adopted as a low-cost, and scalable solution to support crowd management in many applicative fields.

Authors: Boulos Federico , Dall’Asta Luca , Gottardi Giorgio , Abdul Hannan Mohammad , Polo Alessandro , Salas-Sanchez Aaron
Published: March 2020

In this work, the design of monopulse linear arrays generating sum and difference patterns with a partially shared beam forming network is addressed as an inverse problem and solved through a suitable inversion strategy. The array tails are organized into sub-arrays controlled by amplitude weights, while the remaining array elements have two independent amplitude coefficients, one for each beam. The optimal values of both common and independent excitations are determined by means of a convex optimization technique able to retrieve the globally optimal solution whether existing. Sucli a synthesis method allows one to include user- defined upper power bounds on the secondary lobes as well as to arbitrary decide the layout (i.e., the number and the sizes of the sub-arrays) of the common part. Representative results are reported and discussed to assess the effectiveness and the efficiency of the proposed technique.

Published: March 2020

The purpose of this study is to investigate the effects of γ-aminobutyric acid on sleep improvement in mice. According to the method of Technical Standard for Health Food Inspection and Evaluation, animals were divided into three experimental groups. Group 1: Directly inducing sleep and prolonging sleep time experiment; Group 2: Subthreshold dose of sodium pentobarbital for hypnosis experiment; Group 3: Shortening sleep latency experiment. In each experimental group, 40 mice were randomly divided in four subgroups according to their body weight. After 30 days’ oral intake of different doses of γ-aminobutyric acid by mice, it is found that γ-aminobutyric acid can prolong the sleep time of mice hypnotized by pentobarbital sodium and shorten the sleep latency of mice hypnotized by barbital sodium. Meanwhile, there were no obvious abnormal changes in weight of mice. No side-effects were observed during the experiments. These results demonstrate that γ-aminobutyric acid produced by Bloomage Biotechnology Corporation Limited, has sleep aid function.

Authors: Wei Yang
Published: March 2020

The economic and environmental benefits of remanufacturing have been widely recognized.In the context of competition between manufacturers and distributors in closed-loop supply chain.The dynamic evolution process of manufacturer and distributor’s remanufacturing decision-making is analyzed by evolutionary game model. By analyzing the stability of the system, the optimal strategy combination is obtained. The results show that the equilibrium results of system evolution are affected by the authorization fees paid by distributors to manufacturers, the difficulty of recycling remanufactured products and the technical level. When the relationship between profit and authorization fees of remanufactured products changes, the system will evolve to different equilibrium. Finally, the correlation is verified by numerical simulation. Conclusion.

Published: March 2020

In order to explore non-axisymmetric end-wall’s mechanism of secondary flow control in compressor cascade, based on three-dimensional numerical calculation, this paper analysed effects of camber on non-axisymmetric end-wall contouring performance in compressor linear cascades. Results showed that non-axisymmetric end-wall reduces the corner separation loss mainly by suppressing the interaction between the crossflow and the suction surface boundary layer and decreasing the adverse pressure gradient on suction surface. Meanwhile, non-axisymmetric end-wall partly enhances the cross flow, increasing the secondary flow loss. At the incidence of 0°, the increase of the secondary flow loss caused by the non-axisymmetric end-wall plays the leading role when the camber angle is 20°; with the increase of camber angle, the reduction of corner separation loss becomes the leading role. At the incidence of 7°, the hub-corner stall is removed by the non-axisymmetric end-wall when the camber angle increases to 40°, decreasing the loss remarkably.
