Abstract
Releasing the potential of advanced material properties by controlled structuring materials on sub-100-nm length scales for applications such as integrated circuits, nano-photonics, (bio-)sensors, lasers, optical security, etc. requires new technology to fabricate nano-patterns on large areas (from cm2 to 200 mm up to display sizes) in a cost-effective manner. Conventional high-end optical lithography such as stepper/scanners is highly capital intensive and not flexible towards substrate types. Nanoimprint has had the potential for over 20 years to bring a cost-effective, flexible method for large area nano-patterning. Over the last 3–4 years, nanoimprint has made great progress towards volume production. The main accelerator has been the switch from rigid- to wafer-scale soft stamps and tool improvements for step and repeat patterning. In this paper, we discuss substrate conformal imprint lithography (SCIL), which combines nanometer resolution, low patterns distortion, and overlay alignment, traditionally reserved for rigid stamps, with the flexibility and robustness of soft stamps. This was made possible by a combination of a new soft stamp material, an inorganic resist, combined with an innovative imprint method. Finally, a volume production solution will be presented, which can pattern up to 60 wafers per hour.
Design of a Miniaturized X-Band Diplexer Based on Novel One-Third-Mode Substrate Integrated Resonator Filters
Authors: Zhang Hao , Kang Wei , Wu Wen 
Published: June 2017

AbstractIn this paper, a miniaturized diplexer designed with two novel one-third-mode substrate integrated resonator (OTMSIR) filters has been presented. The one-third triangular resonator cavity with two transmission zeros (TZs) and two transmission poles is investigated. TZs are implemented by taking cross couplings of lower order modes in this design. The diplexer is then obtained by integrating two different sizes of OTMSIR filters with a common T-junction structure. A X-band diplexer operating at 10 GHz and 11.5 GHz is designed on a substrate with a dielectric constant of 3.55 to verify the above design concept. This novel structure features more compact size, better transmission performance, higher out of band rejection and easier integration compared with other circuits. A good agreement is obtained between the simulations and the measured results.
Capital Valuation, What is it and Why does it Matter? Insights from Austrian Capital Theory
Authors: Lewin Peter 
Published: June 2017

AbstractThe ability to rationally evaluate time-consuming productive activities is what distinguishes capitalism from alternative social systems. Capital-accounting provides the framework for such evaluations that allow decision-makers to calculate the relative values to them of alternative productive activities. In this paper I show how insights from Austrian Capital Theory help to understand this process of evaluation. Austrian economics stresses that evaluation is an essentially subjective process. Entrepreneurs’ estimates of future earnings, which depend on the consumers’ subjective evaluations of the produced products, will vary and they must compete for productive resources in a dynamic trial and error social process. Entrepreneurial evaluations, nevertheless, can be described in terms of familiar financial concepts that encapsulate both the capital-value and the duration of any contemplated business venture. Value and time are the two essential dimensions of dynamic business valuation. I examine these concepts with a view to describing that social process, using what can be known and what needs to be imagined. I conclude that there is no silver bullet formula or method to evaluate a business that would give an objectively correct answer – obviously not, or else we would not have need of a competitive market process – but there

Abstract
Synthetic resins were introduced in paintings conservation during the 1930s, as an alternative to natural resins, due to their superior resistance to degradation. Their composition usually includes a small amount of additives, such as titanium dioxide. The objective of this work is to study the effect of TiO2 additive on the durability of Paraloid B72 (acrylic resin) and Laropal A81 (urea-aldehyde condensation polymer), both used in art conservation, against photochemical degradation. A methodology involving separating particulate TiO2 from the organic fraction of the resins has been applied, followed by accelerated ageing of the resins in their commercial (C) and modified (M, i.e. after TiO2 removal) has been implemented. The morphological characteristics of resin films were examined through scanning electron microscopy (SEM). Chemical changes, colour properties and photo-chemical stability of the resins were studied with FTIR, UV-Vis absorption spectroscopy and spectro-colorimetry. The results showed a considerably different behaviour between the C and M states of both materials. In particular, C-Paraloid B72 collapses after prolonged irradiation, but within a certain time frame it appears to be relatively stable; on the other hand, C-Laropal A81 is considerably destabilized in comparison to its M state. It can be suggested that TiO2 acts as a UV-blocker for the underlying pigment layers, at the expense of resins’ stability.
Effect of Primary Rocket Jet on Thermodynamic Cycle of RBCC in Ejector Mode
Authors: Lin Binbin , Pan Hongliang , Shi Lei , Ye Jinying 
Published: June 2017

AbstractThrust augmentation in ejector mode is important to improve engine performance so as to enable more propulsion applications of RBCC. Usually, the internal flow-path is configured mainly for combustion organization in ramjet and scramjet modes, thus the RBCC performance in ejector mode will mainly depend on the primary rocket operating parameters and jet expansion state. Considering such restrictions and requirements on the primary rocket, this paper studies the effects of the primary rocket jet on the thermodynamic cycle performance of ejector mode, in which incoming air is dominated by ejector-suction by the primary rocket jet at low flight Mach numbers. It is found that the engine performance in ejector mode will be improved by increasing the primary rocket chamber pressure and nozzle expansion ratio. Furthermore, for better design of primary rocket, primary rocket chamber pressure should be maximized on the basis of ensuring a complete expansion of primary rocket to the ambient pressure at the design point of flight conditions after 3-D CFD simulations for a full flow-path of RBCC including fore-airframe and aft-airframe of a flight vehicle. The results of 3-D numerical simulations show that the bypass ratio and specific impulse increase by 35.5 % and 12.5 % respectively at sea-level static condition.

Published: June 2017

Background
Physiologist-led stress echocardiography (PLSE) services provide potential for expansion of SE services and increased productivity for cardiologists. There are however no published data on the feasibility of PLSE. We sought to assess the feasibility, safety and robustness of PLSE and cardiologist-led stress echocardiography (CLSE) for coronary artery disease (CAD) assessment.

Methods
Retrospective analysis of 898 patients undergoing PLSE or CLSE for CAD assessment using exercise or dobutamine stress over 24 months. PLSE involved 2 cardiac physiologists (exercise) or 1 physiologist plus 1 cardiac nurse (dobutamine). A cardiology registrar was present in the echocardiography department during PLSE in case of medical complications. CLSE involved 1 physiologist and 1 trainee cardiologist who analysed the study and reviewed findings with an imaging cardiologist. Sixteen-segment wall motion scoring (WMS, WMSI) analysis was performed. Feasibility (stressor, image quality, proportion of completed studies, agreement with imaging cardiologist analysis) and safety (complication rate) were compared for PLSE and CLSE.

Results
The majority of studies were CLSE (56.2%) and used dobutamine (68.7%). PLSE more commonly used exercise (69.2%). Overall, 96% of studies were successfully completed (>14 diagnostic segments in 98%, P = 0.899 PLSE vs CLSE). Commencement of PLSE was associated with an increase in annual SE’s performed for CAD assessment. Complication rates were comparably very low for PLSE and CLSE (0.8% vs 1.8%, P = 0.187). There was excellent agreement between PLSE and CLSE WMS interpretation of 480 myocardial segments at rest (κ = 0.87) and stress (κ = 0.70) and WMSI (ICCs and Pearson’s r >0.90, zero Bland–Altman mean bias).

Conclusion
This to our knowledge is the first study of the feasibility of PLSE. PLSE performed by well-trained physiologists is feasible and safe in contemporary practice. PLSE and CLSE interpretation of stress echocardiography for CAD agree very closely.

Abstract
During ongoing proteomic analysis of the soybean (Glycine max (L.) Merr) germplasm collection, PI 603408 was identified as a landrace whose seeds lack accumulation of one of the major seed storage glycinin protein subunits. Whole genomic resequencing was used to identify a two-base deletion affecting glycinin 5. The newly discovered deletion was confirmed to be causative through immunological, genetic, and proteomic analysis, and no significant differences in total seed protein content were found to be due to the glycinin 5 loss-of-function mutation per se. In addition to focused studies on this one specific glycinin subunit-encoding gene, a total of 1,858,185 nucleotide variants were identified, of which 39,344 were predicted to affect protein coding regions. In order to semiautomate analysis of a large number of soybean gene variants, a new SIFT 4G (Sorting Intolerant From Tolerated 4 Genomes) database was designed to predict the impact of nonsynonymous single nucleotide soybean gene variants, potentially enabling more rapid analysis of soybean resequencing data in the future.
Un centro cívico o el réquiem del patrimonio urbano costarricense
Authors: Muñoz Muñoz Marcela 
Published: June 2017

Resumen Se ofrece una honra póstuma a la arquitectura pública de la capital costarricense, San José, como modelo de ciudad nacional. Por medio del estudio de una discusión legislativa se aborda la conveniencia de dotar al país de un centro cívico nacional, la cual favorece la [in]comprensión de un urbanismo incipiente, anterior a 1970, década en la cual se consolida el derecho urbanístico. Mediante el símil del réquiem, la historia del derecho urbanístico reclama la inutilidad de soluciones jurídicas por salvar valiosas edi caciones que vieran la luz en la conformación del Estado Nacional, durante los siglos XIX y XX. El afán de modernidad de Costa Rica requiere que el derecho urbanístico halle nuevas formas de entender el patrimonio urbano. Abstract This article offers a posthumous honor for public architecture of the Costa Rican capital, San José, as a national model of a city. The study of the discussion contained in certain legislative acts around the convenience to give the country a National Civic Center, [do not] favors the understanding of an emerging Urban Planning before 1970’s, the “legal” decade for the Urban Law. By using the analogy of the requiem, the History of Urban Law demands the futility of legal solutions to save valuable buildings that were born in the formation of the National State, during the 19th and 20th centuries. The Costa Rica ́s quest for modernity claims for new ways where Law can understand Urban Heritage.

Authors: Chavarría Núñez Dania 
Published: June 2017

ResumenEn los últimos años se han realizado en Costa Rica algunos esfuerzos para desarrollar normativa urbana que facilite la intervención dentro de las ciudades existentes, con el fin de revitalizar los centros urbanos y atraer nuevamente a la población que por diversas causas renunció a vivir en la ciudad. Las estrategias de Renovación Urbana han desempeñado un papel importante en las transformaciones socio-espaciales que han experimentado muchas ciudades del mundo, las cuales incorporan herramientas novedosas para intervenir dentro del entorno construido y contemplan una serie de instrumentos que permiten corregir las tendencias negativas que genera el modelo de ciudad dispersa, y a su vez devolver la funcionalidad y el atractivo a sectores estratégicos con el fin de construir un nuevo modelo de ciudad más sostenible e inclusiva. El presente artículo tiene como propósito analizar las posibilidades que existen en el país para implementar estrategias de renovación urbana, tomando como marco base la legislación urbana existente. Con el fin de evidenciar este supuesto se analiza la normativa vigente y se pone en evidencia como dicha legislación faculta a los municipios para ejercer competencias en la planificación urbana y el ordenamiento de su territorio. Se da un énfasis particular a la viabilidad para desarrollar e implementar estrategias de renovación urbana en la escala local, la cual se fundamenta en la Ley de Planificación urbana 4240 y se fortalece con los avances más recientes que se han dado en el país en materia de actualización normativa.AbstractIn Costa Rica, in recent years, efforts have been made to develop urban regulations to facilitate intervention within existing cities, with the aim of revitalizing urban centers and attracting the population that for a number of reasons has renounced living in the city. Urban renewal strategies have played an important role in the socio-spatial transformations that have been experienced in those cities around the world which incorporate creative tools to intervene within the built environment and contemplate a series of instruments that allow to correct the negative tendencies generated by the model of dispersed city and at the same time return the functionality and appeal to¡ strategic sectors in order to build a new model of a more sustainable and inclusive city.The purpose of this article is to analyze the possibilities that exist, based on existing urban legislation in the country, to implement strategies of urban renewal. In order to test this assumption, the current legislation is analyzed, evidencing the degree to which it empowers municipalities to exercise its prerogatives in urban planning and the organization of their territory. Particular emphasis is given to the feasibility of developing and implementing urban renewal strategies at the local scale, which is based on the Ley de Planificación Urbana N° 4240 and is strengthened by the most recent advances inthe country in terms of normative update.

ResumenEste Proyecto explora la borrosa interfaz entre tierra y mar, área conocida como litoral. El material que primordialmente constituye tal condición es la arena húmeda, o sedimento. Dicho material sirve de partida para la contemplación de escenarios para el diseño que son alternativos para la zona litoral del Mar Mediterráneo. Paralelo a ello, ambiciona formas en las cuales el papel del arquitecto puede ser mejorado y en las cuales el diseño puede volverse una herramienta relevante para la producción en los litorales. Littoral Negotiations Project se presenta como una especulación acerca del rol del arquitecto, la implementación del diseño y las potenciales consecuencias que podría tener en la generación de escenarios alternativos, para un contexto y territorio específicos: el Mar Mediterráneo. AbstractThis project explores the blurred interface between the land and the sea known as the littoral zone. The very matter from which this condition is constructed is wet sand or sediment. This is the material from which to begin and envisage alternative design scenarios for the littoral zone of the Mediterranean Sea. Parallel to this, the project envisions ways in which Architect’s agency could be enhanced and design can be a relevant tool for the production of littoral zones. Littoral Negotiations Project is presented here as a speculation of the role of the architect, the implementation of design and the potential outcomes it can have in the generation of alternative scenarios for a specific context and territory within the Mediterranean Sea.

In-vivo-Wirksamkeit eines Ohrmedikaments mit Gelatinepulver als Wirkstoffträger bei der Therapie kaniner Otitis externa
Authors: Mueller Ralf , Bouassiba Cosima 
Published: June 2017

ZusammenfassungGegenstand und Ziel: Die Therapie der Otitis externa (OE) erfolgt in der Regel durch tägliche Applikation von Lokaltherapeutika. Längere Applikationsintervalle könnten die Behandlung erleichtern. Die Studie überprüfte anhand klinischer Symptomatik sowie zytologischer und bakteriologischer/mykologischer Befunde die In-vivo-Wirksamkeit eines mit Wirkstoffen angereicherten Gelpräparats mit Marbofloxacin, Dexamethason und Enilconazol im Vergleich zu einem kommerziellen, Marbofloxacin, Dexamethason und Clotrimazol enthaltenden Otologikum. Material und Methoden: Bei 41 Hunden mit OE kam das Gelpräparat (Gruppe A) bzw. ein zugelassenes Otologikum (Gruppe B) zum Einsatz. Ausgewertet wurden 50 Ohren (je 25 pro Gruppe). Das Gelpräparat wurde an Tag 0 und 5 eingebracht und das Kombinationspräparat täglich nach Herstellerangaben appliziert. Klinische und zytologische Kontrollen fanden nach 5 und 10 Tagen statt. Zu Beginn und nach 10 Tagen wurden Tupferproben bakteriologisch sowie mykologisch untersucht. Ergebnisse: Klinisch und zytologisch ließ sich zwischen den Gruppen kein signifikanter Unterschied feststellen. In beiden Gruppen war die Steigerung negativer bakteriologischer Befunde vergleichbar. In Gruppe A wurden nach 10 Tagen signifikant mehr marbofloxacinresistente Isolate identifiziert, obwohl der Wirkstoff Marbofloxacin in vitro über einen Zeitraum von 15 Tagen noch zu über 98% verfügbar war. Schlussfolgerung: Die zweimalige Anwendung des mit definierten Wirkstoffen angefertigten Gels kann klinisch und zytologisch als vergleichbar mit der täglichen Anwendung eines zugelassenen Otologikums angesehen werden. Die Gefahr einer Resistenzentwicklung gegen Fluorchinolone ist bei Anwendung des Gels im Vergleich zu dem zugelassenen Otologikum eher vorhanden. Lokale Nebenwirkungen könnten bei Anwendung des Gels auftreten. Klinische Relevanz: Ein mit Wirkstoffen versehenes Gelatinepräparat kann bei Otitis externa des Hundes eine Alternative zur täglichen Applikation von Lokaltherapeutika sein. Die Entwicklung von Resistenzen ist möglich.

Published: June 2017

The olive trees (Olea europaea L.) have been cultivated for millennia in the Mediterranean basin and its oil has been an important part of human nutrition in the region. In order to distinguish between olive accessions, morphological and biological characters have been widely and commonly used for descriptive purposes and have been used to characterize olive accessions. A comparative study of morphological characters of olive accessions grown in Tunisia was carried out and analyzed using Bayesian Networks (BN) and Principal Components Analysis (PCA). The obtained results showed that averages of fruit and kernel weights were 2.27 grams and 0.41 grams, respectively. Besides, a relatively moderate level of variation (51.22%) being explained by four Principal components. BN revealed that geographical localisation plays a role in the increase of tree habit, size of lenticels and leaf shape. A dendrogram has been carried out in the aim to classify studied olive accessions. We proposed a novel method of analysis based on the three-step scheme, in which first the data set is clustered, then olive tree features are evaluated. The studied accessions can be divided into four main groups by cutting the dendrogram at a similarity value of 0.645. Different relationships are studied and highlighted, and finally the collected features are subjected to a global principal component analysis. Obtained results confirmed that core surface was negatively correlated with geographical location (r = -0.52, p<0.05) and maturation period r = -0.539, p<0.05). Number of lenticels was positively correlated to lenticels size (r = 0.632, p<0.05). Core shape had a negative correlation with fruit shape (r = -0.759, p<0.05). On the basis of these findings, this research confirmed that morphological markers are a preliminary tool to characterize olive oil accessions.
