Possible signatures of mixed-parity superconductivity in doped polar SrTiO3 films

Superconductors that possess both broken spatial inversion symmetry and spin-orbit interactions exhibit a mix of spin singlet and triplet pairing. Here, we report on measurements of the superconducting properties of electron-doped, strained SrTiO3 films. These films have an enhanced superconducting transition temperature and were previously shown to undergo a transition to a polar phase prior to becoming superconducting. We show that some films show signatures of an unusual superconducting state, such as an in-plane critical field that is higher than both the paramagnetic and orbital pair breaking limits. Moreover, nonreciprocal transport, which reflects the ratio of odd versus even pairing interactions, is observed. Together, these characteristics indicate that these films provide a tunable platform for investigations of unconventional superconductivity

Visual Field Analysis: A reliable method to score left and right eye use using automated tracking

Brain and behavioural asymmetries have been documented in various taxa. Many of these asymmetries involve preferential left and right eye use. However, measuring eye use through manual frame-by-frame analyses from video recordings is laborious and may lead to biases. Recent progress in technology has allowed the development of accurate tracking techniques for measuring animal behaviour. Amongst these techniques, DeepLabCut, a Python-based tracking toolbox using transfer learning with deep neural networks, offers the possibility to track different body parts with unprecedented accuracy. Exploiting the potentialities of DeepLabCut, we developed Visual Field Analysis, an additional open-source application for extracting eye use data. To our knowledge, this is the first application that can automatically quantify left–right preferences in eye use. Here we test the performance of our application in measuring preferential eye use in young domestic chicks. The comparison with manual scoring methods revealed a near perfect correlation in the measures of eye use obtained by Visual Field Analysis. With our application, eye use can be analysed reliably, objectively and at a fine scale in different experimental paradigms

Machine-Readable Privacy Certificates for Services

Privacy-aware processing of personal data on the web of services requires managing a number of issues arising both from the technical and the legal domain. Several approaches have been proposed to matching privacy requirements (on the clients side) and privacy guarantees (on the service provider side). Still, the assurance of effective data protection (when possible) relies on substantial human effort and exposes organizations to significant (non-)compliance risks. In this paper we put forward the idea that a privacy certification scheme producing and managing machine-readable artifacts in the form of privacy certificates can play an important role towards the solution of this problem. Digital privacy certificates represent the reasons why a privacy property holds for a service and describe the privacy measures supporting it. Also, privacy certificates can be used to automatically select services whose certificates match the client policies (privacy requirements). Our proposal relies on an evolution of the conceptual model developed in the Assert4Soa project and on a certificate format specifically tailored to represent privacy properties. To validate our approach, we present a worked-out instance showing how privacy property Retention-based unlinkability can be certified for a banking financial service.Comment: 20 pages, 6 figure

IDENTIFIKASI PERSEPSI MASYARAKAT TERHADAP PENERAPAN IDENTITAS VISUAL PADA ELEMEN INTERIOR COWORKING SPACE DIGITAL VALLEY

Abstract: Modern life encourages the creation of new patterns of worker relations and various ways of working. A co-working space is a facility created because of these changes. Not all of the existing co-working spaces have the same goals and concepts. The need for a brand identity to provide differentiation from other co-working spaces can be done through the implementation of a visual identity in the interior so that it is easy for consumers to remember. This study will discuss the identification of public perceptions in spatial planning, use of color, material selection, use of lighting types, application of forms, and use of furniture in Co-working Space Digital Valley. This study uses a descriptive qualitative method which is carried out by analyzing the theory of brand identity applications on the interior design elements of the Digital Valley Co-working Space. The data collection method used is the method of observation and questionnaires. Questionnaires are used as an analysis of public perceptions with the determination of respondents using random sampling. The results show that the application of visual identity in Co-working Space Digital Valley is still less than optimal based on three fundamental components that have a strong impact on the existence of a brand, which can be seen from the perceptions of respondents who show neutral and negative responses on several criteria. This research can be used as a consideration in the application of visual identity in Co-working Space Digital Valley.Abstrak: Kehidupan modern yang mendorong terciptanya pola hubungan pekerja baru dan berbagai macam cara dalam bekerja.

Evolution of Martensitic Microstructure on Carbon Steel Tempered at Low Temperatures

This work presents the microstructural changes of a carbon steel during tempering at low temperatures (first stage of tempering), and its effects in the second and third stages. These changes are determined by internal friction. Internal friction is measured in a forced vibration mode at 5 Hz, in a temperature range from 300 to 600K. Four internal friction peaks appear: S1 at 350K, P1 at 380K, P2 at 440K, P3 at 480K. S1 only appears in the sample tempered at 380K for 20 hours, and this can be related to the reduction of the martensite tetragonality. The height of P1 is lowest when the intensity of tempering is increased. This height can be related to the quantity of epsilon carbide than precipitate. The heights of P2 and P3 are not changed significantly, but the difference of temperature between both is lowest when the tempering intensity is increased. This suggests than the dissolution of epsilon carbide and formation of cementite takes places in a lowest range of temperature.Fil: Hoyos, J.. Comisión Nacional de Energía Atómica.

Methods for immobilizing receptors in microfluidic devices: A review

In this review article, we discuss state-of-the-art methods for immobilizing functional receptors in microfluidic devices. Strategies used to immobilize receptors in such devices are essential for the development of specific, sensitive (bio)chemical assays that can be used for a wide range of applications. In the first section, we review the principles and the chemistry of immobilization techniques that are the most commonly used in microfluidics. We afterward describe immobilization methods on static surfaces from microchannel surfaces to electrode surfaces with a particular attention to opportunities offered by hydrogel surfaces. Finally, we discuss immobilization methods on mobile surfaces with an emphasis on both magnetic and non-magnetic microbeads, and finally, we highlight recent developments of new types of mobile supports

Microscale Interfacial Polymerization on a Chip

Forming hydrogels with precise geometries is challenging and mostly done using photopolymerization, which involves toxic chemicals, rinsing steps, solvents, and bulky optical equipment. Here, we introduce a new method for in situ formation of hydrogels with a well-defined geometry in a sealed microfluidic chip by interfacial polymerization. The geometry of the hydrogel is programmed by microfluidic design using capillary pinning structures and bringing into contact solutions containing hydrogel precursors from vicinal channels. The characteristics of the hydrogel (mesh size, molecular weight cut-off) can be readily adjusted. This method is compatible with capillary-driven microfluidics, fast, uses small volumes of reagents and samples, and does not require specific laboratory equipment. Our approach creates opportunities for filtration, hydrogel functionalization, and hydrogel-based assays, as exemplified by a rapid, compact competitive immunoassay that does not require a rinsing step

Expressão gênica em grãos de café submetidos a diferentes tratamentos pós-colheita-uma análise preliminar.

O conhecimento sobre como os tipos de processamento pós-colheita interferem na qualidade final de bebida é essencial para que cafés com qualidades especiais possam ser desenvolvidos. Dentre as características que podem ser diretamente influenciadas pelo processamento, a composição química do grão é a de maior interesse. Fatores como a regulação da expressão de genes e a atividade de enzimas específicas são determinantes para esta composição. Neste contexto, o objetivo deste estudo preliminar foi avaliar como os processamentos por via seca e úmida afetam o padrão de expressão dos genes isocitrato liase (ICL), ?-mananase (MAN) e ?-galactosidase (GAL). Frutos cereja foram submetidos a condições de secagem natural, despolpamento e desmucilamento. A expressão dos genes foi quantificada pela metodologia de RT-PCR em tempo real. A análise comparativa da expressão dos 3 genes indicou que no processamento via seca a expressão de ICL e MAN nas sementes foi maior do que em sementes de frutos processados por via úmida. Para o gene GAL, não foram observadas diferenças expressivas no perfil de expressão em sementes dos frutos submetidos aos diferentes tratamentos. Esses resultados diferiram dos obtidos em outros estudos já descritos na literatura, em que, apesar de ter sido avaliada a expressão de genes, foram utilizadas etapas de processamento distintas das utilizadas neste trabalho. Esses resultados revelaram, portanto, que há necessidade de se padronizarem os processamentos experimentais em pesquisas visando avaliar efeitos dos tratamentos pós-colheita sobre a qualidade do café
