Published: December 2018

Abstract
Recent advancement of flexible wearable electronics allows significant enhancement of portable, continuous health monitoring and persistent human-machine interfaces. Enabled by flexible electronic systems, smart and connected bioelectronics are accelerating the integration of innovative information science and engineering strategies, ultimately driving the rapid transformation of healthcare and medicine. Recent progress in development and engineering of soft materials has provided various opportunities to design different types of mechanically deformable systems towards smart and connected bioelectronics. Here, we summarize the key properties of soft materials and their characteristics in the context of wearable sensors and electronics. Details of functionality and sensitivity of the bioelectronics are discussed with applications in health, medicine, and machine interfaces. In addition, we introduce recent examples of bioelectronics that offer persistent human-machine interfaces to control prosthetic hands, wheelchairs, or computer interfaces.
Screen Printing Fine Pitch Stretchable Silver Inks onto a Flexible Substrate for Wearable Applications

Published: December 2018

Abstract
The lightweight and bendable features of printed flexible electronics are increasingly attractive. Currently stretchable silver inks are formulated for wide traces, typically larger than 2 mm. To attach ultra-thin silicon chips that have fine pitch onto printed organic substrate, it is necessary to print fine trace width/space that matches the pitch of the chips, which may be less than 200 microns.
This paper presents the development and optimization of the screen printing process for printing stretchable silver ink onto stretchable thermoplastic polyurethane (TPU) substrate. A test vehicle was designed including 50 μm/5 mm (line width/line length) to 350 μm/35 mm lines (at 4 biases). The stretchable ink selected was DuPont PE 873 and Dupont's PE 5025 ink (non-stretchable conductive flake silver) was used as a “control” to baseline the printing process. The substrate used was Bemis TPU ST604. The experiment was done on a DEK Horizon 03i printer. A DEK squeegee 200 (Blue) and a DEK 265 flood bar (200 mm) were used. A 2-level factorial design with three replicates was selected to investigate the effect of process parameters on the quality of prints. The quality of the prints is characterized by 1) resistance of traces, 2) sheet resistance, 3) z-axis height, and 4) trace width/spacing.
We observed significant noise in the z-axis printed silver ink height measured by profilometry and concluded z-axis height is not a good response variable for characterizing screen printing stretchable silver ink onto TPU substrate, mainly due to high roughness of the TPU substrate. We proposed calculated sheet resistance based on the measured resistance value, trace width, and trace length, which can replace trace height measurements on rough profile substrates.
We found that squeegee pressure and emulsion thickness have statistically significant effects on calculated sheet resistance of print traces while print speed does not have statistically significant effects. In our experiment setting levels, the lower the squeegee pressure, the lower the calculated sheet resistance that is achieved. The emulsion with higher emulsion over mesh (EOM) is better than the emulsion with lower EOM since it can achieve lower sheet resistance. After optimizing the screen printing process, we were able to print 100 μm (4 mils) trace width and spacing with high consistency.

Published: December 2018

Abstract
Sensors as devices can be considered the most advanced microelectronics systems built by connecting different types of microchips as micro-mechanical structure (MEMS) and Application Specific Integrated Circuit (ASIC). These Systems in Package (SiP) use mostly an epoxy resin material whose major reliability concern is the moisture absorption after humidity exposure so that the electrical interconnections between the dies become surrounded by a non-waterproof material. This article describes how the real resin morphology influences the electrical signals provided by a MEMS to an ASIC in an inertial sensor SiP. In particular, the study is focused on the pads area of the MEMS, where a large surface of polysilicon is in direct contact with the resin. As the epoxy structure close to the above regions may be affected by a non-homogeneous distribution of fillers, the compound humidity sensitivity may locally increase and the electrical properties may be conditioned in the same way. The goal of this study is to define a suitable method to quantify and characterize the local change of the resin properties after moisture absorption. After deeply analyzing the results of the standard electronics measurements methods an electrochemical approach has been selected as the best appropriate one to match the physical reality.

O O presente estudo resultou da investigação e da prática pedagógica no quadro de um Mestrado em Ensino do 1.º Ciclo do Ensino Básico e de Português e História e Geografia de Portugal no 2.º Ciclo do Ensino Básico[i], desenvolvido na Universidade do Minho e em escolas cooperantes.Visa descrever e refletir sobre atividades e estratégias promotoras do conhecimento acerca da composicionalidade dos textos, em rigor sobre o que define e distingue diferentes tipos textuais; no quadro destes, é dedicada especial atenção ao género de divulgação científica mediática, especialmente por contraste com outros géneros.É importante que os alunos desenvolvam estratégias para a compreensão de textos e aumentem o domínio das regras de construção de diferentes tipos de texto, uma vez que estes mostram ter dificuldades, quer na receção/compreensão, quer na produção/estruturação de textos. Para o efeito, este estudo reconhece e fundamenta-se no relevo do conhecimento linguístico, ao nível macrotextual, para a promoção das competências de leitura e escrita. E não ignora que, na formação dos futuros docentes, o conhecimento da composicionalidade textual não pode ser negligenciado.[i] Em Portugal, o ensino básico encontra-se dividido em três ciclos: o primeiro corresponde aos primeiros quatro anos de escolaridade; o segundo aos dois anos seguintes; e o terceiro aos três anos finais. Completam-se, assim, nove anos de escolaridade, que os alunos iniciam aos seis anos de idade.
A confined–unconfined aquifer model for subglacial hydrology and its application to the Northeast Greenland Ice Stream
Authors: Beyer Sebastian , Kleiner Thomas , Aizinger Vadym , Rückamp Martin , Humbert Angelika 
Published: December 2018

Abstract. Subglacial hydrology plays an important role in ice sheet dynamics as it determines
the sliding velocity. It also drives freshwater into the ocean, leading to undercutting of calving fronts by plumes.
Modeling subglacial water has been a challenge for decades. Only
recently have new approaches been developed such as representing subglacial channels
and thin water sheets by separate layers of variable hydraulic conductivity.
We extend this concept by modeling a confined–unconfined
aquifer system (CUAS) in a single layer of an equivalent porous medium (EPM). The advantage of this formulation is
that it prevents unphysical values of pressure at reasonable computational
cost. We performed sensitivity tests to investigate the effect of
different model parameters. The strongest influence of model parameters was
detected in terms of governing the opening and closure of the system. Furthermore,
we applied the model to the Northeast Greenland Ice Stream, where
an efficient system independent of seasonal input was identified about
500 km downstream from the ice divide.
Using the effective pressure from the hydrology model, the Ice
Sheet System Model (ISSM) showed considerable improvements in
modeled velocities in the coastal region.
“Such as might have arisen only out of hell”: A Note on Poe’s Hellenic Motifs in “The Black Cat”
Authors: Tsokanos Dimitrios , Ibáñez José R. 
Published: December 2018

Edgar Allan Poe’s “The Black Cat” has received a great deal of scholarly attention over the years from a variety of perspectives, not least the domestic and symbolic presence of Pluto in the story. Kent Ljungquist (1980) saw Poe’s narrative in terms of classical literary tradition, specifically the notion of the daemonic, yet confined his study to Pluto’s demonic features, arguing that the cat may be an infernal spirit sent to castigate the narrator. Other studies, such as Clark Moreland and Karime Rodriguez (2015), have reached similar conclusions. However, there is a surprising absence in the literature of any discussion of Poe’s decision to name the ‘phantasm’ of his narrative after the Hellenic god of the Underworld. The present paper seeks to address this, and proposes that Poe’s Pluto may not simply function as a demonic spirit, but rather as the Pluto of Hellenic mythology himself.

Published: December 2018

The paper assessed the maintenance practices of traditional public stadia in Ghana. It also sought to evaluate the current state, causes, and effects of poor maintenance practices on the stadia. The study used structured questionnaires administered to 60 maintenance managers, equipment officers, and property officers. The questionnaire administration was done using the purposive sampling technique. The findings show that failing to respond on time, routine inspection, stadium design and structure and utilization of unstandardized material were perceived by respondent as the main causes of poor maintenance practices. The findings of this study indicate that poor maintenance practices have effects on the full usage of the public stadia. The results clearly indicate that the grievances are mainly man-made.The paper contributes to the literature on the practices of maintenance of public infrastructure especially for West Africa countries and other emerging countries. The study may be great to professionals on the key activities in the esteem of best maintenance management practices on stadia in Ghana and beyond.
Quantitative Late Quaternary Climate Reconstruction from Plant Macrofossil Communities in Western North America
Authors: Harbert Robert S. , Nixon Kevin C. 
Published: December 2018

The Late Quaternary packrat (Neotoma spp.) midden plant macrofossil record in western North America is an exceptional record of biotic change that provides strong evidence of past climate. In this study, we generate quantitative estimates of climate from plant community composition of more than 600 individual paleomiddens over the past 50,000 years. Here we present the first large-scale application of CRACLE (Climate Reconstruction Analysis using Coexistence Likelihood Estimation), a quantitative climate inference method that uses plant community composition as a climate proxy under the individualistic concept of plant community assembly. The results are spatiotemporally specific estimates of temperature, precipitation, available moisture, and seasonal patterns that are consistent with well understood global climate patterns but provide previously unavailable detail and precision of the regional paleoclimate in western North America. Rapid warming is estimated at the Pleistocene-Holocene transition, at a conservative estimate of ca. 1°C per millennium. Previously projected future temperature increases suggest a rate of increase of more than 2°C over the next century, an astonishing 10× the rate experienced at any point during the past 50,000 years in Western North America. These analyses form a baseline demonstration of how the growing paleoecological record of packrat midden plant macrofossils can provide quantitative estimates of paleoclimate that aid in understanding the complexities of, and biotic responses to the regional climate system. This work is the first synthetic application of any paleoclimate estimation method to packrat midden plant macrofossils.
On disintegration of the Emil Jaques-Dalcroze method in the Polish music education system. Reflections on the role of Dalcroze’s solfeggio in a 1st-level music school
Authors: Pasternak Anetta , Trzepierczyńska Agata 
Published: December 2018

The method of Emil Jaques-Dalcroze’s eurhythmics combines the three integral, equivalent aspects: eurhythmics, solfeggio and improvisation, which complement each other and thus constitute a coherent, comprehensive and multi-sensory method of music education. The method was successfully transplanted onto the Polish music education system and appeared in curricula for grades 1-3 of the 1st-level music schools in 1976 as an integrated subject named ‘music learning with eurhythmics.’ In 2nd-level music schools, eurhythmics faculties were opened as early as in the 1950s and initiated the training process of future specialists in the Dalcroze method. Finally, as a result of numerous reforms in music education system, the primary school subject was decomposed into ‘eurhythmics’ and ‘aural training.’ The decision on separating the subjects disturbed the concept of an integral training process, included within Dalcroze’s method. This was due to the fact that Dalcroze’s solfeggio took secondary priority to other methods used in aural training, as it is currently possible for music theorists and other specialists to give lessons in this subject. Therefore, two important questions should be asked:
1. Does the reduction of the solfeggio role undermine the entire concept of Dalcroze’s eurhythmics nowadays?
2. Is the use of movement in aural training still necessary?
Quantification du décrochage scolaire au Québec et en France : effets de perspective et jeux d’échelle1
Authors: Moulin Stéphane , Verdier Éric , Doray Pierre , Prévost Jean-Guy 
Published: December 2018

Cet article analyse les instruments de quantification de l’action publique contre le décrochage scolaire en France et au Québec. Cette comparaison d’une instrumentation replacée dans son contexte national permet de s’interroger sur les effets de perspective engendrés par le recours à une grande variété d’outils de quantification. L’évaluation de l’ampleur du phénomène appelle une démarche multiscalaire : nationale certes, mais indissociablement supranationale et régionale, ou même locale. Il s’avère que les exigences de l’instrumentation statistique se sont déplacées au cours du temps d’une priorité donnée à la comparaison interétatique vers une priorité donnée à l’estimation d’indicateurs régionaux ou locaux en vue de mobiliser et d’outiller les acteurs de terrain. Est ainsi révélé le rôle politique de la variété des définitions (des mises en équivalence), des indicateurs (fréquences ou pourcentages), des échelles d’ordonnancement et seuils de comparaison : ils fournissent in fine des répertoires rhétoriques aux acteurs nationaux et régionaux qu’ils mobilisent tantôt pour accréditer l’urgence d’agir tantôt pour démontrer l’efficacité de l’action entreprise.
