Visualizing Human Protein‐Protein Interactions and Subcellular Localizations on Cell Images Through CellMap

2020

Visualizing protein data remains a challenging and stimulating task. Useful and intuitive visualization tools may help advance biomolecular and medical research; unintuitive tools may bar important breakthroughs. This protocol describes two use cases for the CellMap (http://cellmap.protein.properties) web tool. The tool allows researchers to visualize human protein-protein interaction data constrained by protein subcellular localizations. In the simplest form, proteins are visualized on cell images that also show protein-protein interactions (PPIs) through lines (edges) connecting the proteins across the compartments. At a glance, this simultaneously highlights spatial constraints that prot…

An Interactive Framework for Offline Data-Driven Multiobjective Optimization

2020

We propose a framework for solving offline data-driven multiobjective optimization problems in an interactive manner. No new data becomes available when solving offline problems. We fit surrogate models to the data to enable optimization, which introduces uncertainty. The framework incorporates preference information from a decision maker in two aspects to direct the solution process. Firstly, the decision maker can guide the optimization by providing preferences for objectives. Secondly, the framework features a novel technique for the decision maker to also express preferences related to maximum acceptable uncertainty in the solutions as preferred ranges of uncertainty. In this way, the d…

Attributional and relational influence of numerals in S’ncamtho metaphors

2020

AbstractYouth varieties in Africa such as S’ncamtho, the Ndebele-based youth variety in Zimbabwe, and urban vernaculars interact with urban and modern experiences which offer them new materials and experiences to base their metaphors on compared to older metaphors in the base languages. This paper explores the use of numeral qualities and associations in the conceptualisation and orthographic representation of S’ncamtho metaphors. S’ncamtho is popular with urban youth and this makes social media platforms such as Twitter, Facebook, WhatsApp, SMS and Instagram key in the performance of the youth variety, a performance that includes the creation, use and contraction of metaphors. Numerals off…

Towards Bankruptcy Prediction: Deep Sentiment Mining to Detect Financial Distress from Business Management Reports

2018

Due to their disclosure required by law, business management reports have become publicly available for a large number of companies, and these reports offer the opportunity to assess the financial health or distress of a company, both quantitatively from the balance sheets and qualitatively from the text. In this paper, we analyze the potential of deep sentiment mining from the textual parts of business management reports and aim to detect signals for financial distress. We (1) created the largest corpus of business reports analyzed qualitatively to date, (2) defined a non-trivial target variable based on the so-called Altman Z-score, (3) developed a filtering of sentences based on class-co…

On the Objective Evaluation of Motion Cueing in Vehicle Simulations

2021

Motion-based simulators are used for a variety of applications, such as research, education, entertainment and training. In fact, motion cues are required to achieve the highest regulatory certifications in training vehicle simulators. Nonetheless, the reproduction of self-motion cues presents technological and economic limitations that are not present in the generation of audiovisual cues. For this reason, the generated motion does not generally match the expected one. Therefore, it is necessary to define means to assess the suitability/fidelity of the generated motion cues. After more than 50 years of motion-based vehicle simulation, no mechanism has been universally accepted as the stand…

Processing of 3D Models for Networking of CH in Geomatics

2020

In recent times the possibility of reconstruction of complex 3D Cultural Heritage (CH) environments has opened new scenarios for touristic and scientific aims. The different needs for networking or conservation purposes of CH lead to study proper structuring of 3D models. In light of this, a scientific approach has been developed in order to test the networking capabilities, comparing different loading configurations of 3D environments with multiple combinations of 3D models inside them, considering different solutions. This experimentation has been based on WebGL-HTML5 technologies and allowed to discover the true balance between performances of proposed system, the quality of visualizatio…

Digital Technologies for the Fruition of Archaeological Heritage. The Visualisation of the Temple C Metopes Polychrome in Selinunte

2019

Through the tools of the representation this paper investigates a hypothetical virtual re-presentation of the metopes original polychromies. The reconstructive interpretative process was carried out through a critical reading of historical and iconographic sources. Starting from the reading of drawings made by Angell and Harris at the time of the archaeological finds, of Hittorff’s studies and watercolors, and of some coloured fragments still observable in the original metopes, the graphic elaborations that simulate the original polychromes have been prepared. The purpose of this study and of the analysis here described is the experimentation of an interactive visualisation application (aug…

3D visualization of engendering collaborative leadership in the space

2012

The paper focuses on collaborative leadership in education and how to illustrate its engendering process in a three-dimensional space. This complex and fluid process is examined as distributed and pedagogical within a Finnish vocational upper secondary educational organization. As a consequence, the notion of distributed pedagogical leadership is used when collaborative leadership in education is studied. Collaborative leadership is argued to consist of the innermost substance of a professional learning community, as attributes of a group of people working together for specific purposes. Therefore, collaborative leadership naturally involves actors, activities, and context. However, the inn…

Visual Data Mining : Real Applications and New Approaches

2014

En los últimos años, la visualización de datos se ha convertido en un área muy activa y vital de la investigación. Es una manera eficaz de analizar grandes cantidades de datos para identificar correlaciones, tendencias, valores extremos, patrones, entre otra mucha información. Los datos sin procesar a menudo carecen de sentido, pero representar dichos datos visualmente ofrece al público un contexto importante para entender la información contenida en ellos. Debido a la importancia de esta área de investigación, y a su novedad, esta tesis se centra en esta temática y pretende descubrir nuevos hallazgos, extraer conclusiones y legar contribuciones relevantes a la comunidad científica en dicho…
