Oil spills detection through a marine environment monitoring system
Moroni D., Pieri G., Salvetti O., Tampucci M.
The ability to detect and monitor oil spills at sea is becoming more and more important due to the high demand of oil based products and to the increase in maritime traffic density. Remote sensing frameworks have been proved to yield accurate results in the case of major events; nonetheless also medium and micro oil spills are of their own importance, especially in protected areas that deserve special attention. In this paper, we propose a monitoring framework based on the collection of in-situ observations and on their integration with remote sensing in order to fill out existing observational gaps. A risk assessment model is included for providing environmental decision support and for generating alerts in case of potentially dangerous situations. Field operational tests in an area of great environmental interest demonstrate the technical validity of the approach.Source: IBIMET 2014 - Fifth International Symposium Monitoring of Mediterranean Coastal Areas: problems and measurement techniques, pp. 440–448, Livorno, Italy, 17-19 June 2014

Thesaurus: un database per il patrimonio culturale sommerso
La Monica D., Costa S., Pace G., Martinelli M., Salvetti O., Tampucci M., Righi M.
Thesaurus Project aims at promoting the knowledge of the underwater cultural heritage, ancient and modern, through the application of several typologies of tools: underwater autonomous vehicles, which will be able to explore the sea bottom in teams communicating with each other; a database, which will be useful to store and manage all the information referring to archaeological or historical objects, shipwrecks and sites. This paper aims to explain the logic structure of the database indicating the particular needs of the research, the different typologies of items which have to be managed (archaeological and historical objects; ancient, medieval or modern shipwrecks; underwater sites; written or figurative sources, etc.), the relation with other similar databases and projects. The main task of this part of Thesaurus is to plan and organize an IT system, which will allow archaeologists to describe information in detail, in order to make an efficient managing and retrieving data system available.Source: Archeologia e calcolatori 25 (2014): 51–69.

WP1-CNR-ISTI - Ricostruzione di reti di regolazione genica da dati trascrittomici
Caudai C.
Some recently proposed approaches to identify genetic regulatory mechanisms from sequencing experiments are briefly described. Since gene expression is influenced by biologica processes in the cell, and both the processes and the related transcription factors are largely unknown, many attempts have been made to solve this problem by blind source separation techniques. We analyse some of these approaches, each based on a linear data model.Source: WP1-CNR-ISTI, 2014

Progettazione e realizzazione di applicazioni Web integrate in un portale accessibile
Righi M.
Per svolgere l'attività relativa all'assegno di ricerca è stato scelto di utilizzare software freeware e Open Source con il fine di promuovere lo stesso e di contenere i costi dello sviluppo. Durante lo studio delle applicazioni Web da integrare è stata individuata la necessità di avere applicazioni per la gestione dei contenuti, del personale, dei processi decisionali, della pubblicazione dei risultati ecc. L'integrazione delle applicazioni studiate per risolvere le necessità individuate ha portato ad una strategia di sviluppo che, abbracciando la filosofia del software freeware, Open Source e applicando le regole della riusabilità, conduce naturalmente a gestire un insieme di ambienti disomogenei, non integrati. Infatti, i software freeware ed Open Source sono strumenti per risolvere specifiche esigenze ed è nelle mani dello studioso capire come integrarli e riuscire a realizzare uno strumento omogeneo e accessibile. Ecco quindi che nasce l'esigenza di unire alla flessibilità di questi software l'integrazione tra i servizi. Da questo punto di vista inizia il lavoro di seguito descritto.

Ricostruzione tridimensionale della struttura della cromatina da dati tipo Chromosome Conformation Capture. Nota riservata, progetto InterOmics
Caudai C.
This document reports part of the WP1-ISTI unit activity in the framework of the national Flagship Project InterOmics, on the 3D chromatin structure analysis from Hi-C experiments. Compared with other methods presented in the literature, our approach uses a new solution model incorporating sound prior knowledge, and a new reconstruction criterion that does not require an explicit translation of the Hi-C data into Euclidean distances between pairs of genomic loci. This approach also allows us to solve the problem in a multiscale setting, by reconstructing significant fragments separately at high resolution and then putting them together through the same criterion applied to lower-resolution data.Source: WP1-CNR-ISTI, 2014

SHREC'14 Track: Retrieval and Classification on Textured 3D Models
Biasotti S., Cerri A., Abdelrahman M., Aono M., Ben Hamza A., El-melegy M., Farag A., Garro V., Giachetti D., Giorgi D., Godil A., Li C., Liu Y., Martono H., Sanada C., Tatsuma A., Velasco-forero S., Xu C.
This paper reports the results of the SHREC'14 track: Retrieval and classification on textured 3D models, whose goal is to evaluate the performance of retrieval algorithms when models vary either by geometric shape or texture, or both. The collection to search in is made of 572 textured mesh models, having a two-level classification based on geometry and texture. Together with the dataset, a training set of 96 models was provided. The track saw eight participants and the submission of 22 runs, to either the retrieval or the classification contest, or both. The evaluation results show a promising scenario about textured 3D retrieval methods, and reveal interesting insights in dealing with texture information in the CIELab rather than in the RGB colour space.Source: Eurographics Workshop on 3D Object Retrieval (2014), pp. 111–120, Strasbourg, France, April 6, 2014

Non-conventional electrochemical and optical sensor systems
Di Natale C., Dini F., Scozzari A.
Electroanalytical methods are a common tool for the assessment of chemical peculiarities of aqueous solutions. Also, the analysis of water based on optical sensors is a mature field of research, which already led to industrial applications and standard laboratory practices. Nevertheless, scientific literature is still offering new sensor techniques and innovative measurement approaches in both fields. In particular, for fast characterisation of liquids and change detection applications in a continuous monitoring context, the technology of taste sensors based on electrochemical techniques is still witnessing a growing interest. Such devices are often defined as "electronic tongues" or "e-tongues". In addition, emerging inexpensive and portable devices with optical-sensing capabilities can be used for monitoring applications with a novel approach. This chapter gives an overview of recent techniques developed in both fields and presents several potential applications and case studies that deal with the context of water quality assessment. A brief introduction about the basics of each measurement technology, even if not exhaustive, is also provided.Source: Threats to the Quality of Groundwater Resources: Prevention and Control, edited by A.

SuperResolution-aided recognition of cytoskeletons in scanning probe microscopy images
D'Acunto M., Colantonio S., Righi M., Salvetti O.
In this paper, we discuss the possibility to adopt SuperResolution (SR) methods as an important preparatory step to Pattern Recognition, so as to improve the accuracy of image content recognition and identification. Actually, SR mainly deals with the task of deriving a high-resolution image from one or multiple low resolution images of the same scene. The high-resolved image corresponds to a more precise image whose content is enriched with information hidden among the pixels of the original low resolution image(s), and corresponds to a more faithfully representation of the imaged scene. Such enriched content obviously represents a better sample of the scene which can be profitably used by Pattern Recognition algorithms. A real application scenario is discussed dealing with the recognition of cell skeletons in Scanning ProbeMicroscopy (SPM) single image SR. Results show that the SR allows us to detect and recognize important information barely visible in the original low-resolution image.Source: ICPRAM 2014 - 3rd International Conference on Pattern Recognition Applications and Methods, Angers, France, 6-8 March 2014

ITACA - Rapporto di valutazione su vantaggi e svantaggi delle diverse classi di tecniche di watermarking invisibile in relazione agli scopi del progetto
Salerno E.
This report contains three separate documents: state of the art in digital watermarking; assessment of two different methods for robust and invisible watermarking; experiments on the method chosen for project ITACA. These three parts have been archived as confidential reports 2013-PR-005, 2013-PR-004, and 2014-PR-001, respectively, in the ISTI-CNR publication management system. The coarsest classification of watermarking includes space-domain and transformed-domain methods. ITACA's need to watermark multi-channel images also entails a choice of a specific algorithm that maintains robustness and transparency in both the entire data cube and any part thereof, depending on the intended use of the data. After a general assessment, two methods have been selected that are suitable for ITACA, one working in the space domain and one working in the singular vector domain. After the first experiments, the algorithm in the space domain has been chosen to be examined more in depth. The result of this further study is an algorithm that has already been proposed in the literature, slightly modified to be used at ITACA's purposes of color/multispectral data images. The extraction procedure, in particular, does not rely on ICA techniques.

Boron nitride nanotube-functionalised myoblast/microfibre constructs: a nanotech-assisted tissue engineered platform for muscle stimulation
Danti S., Ciofani G., Pertici G., Moscato S., D'Alessandro D., Ciabatti E., Chiellini F., D'Acunto M., Mattoli V., Berrettini S.
In this communication, we introduce boron nitride nanotube (BNNT)-functionalised muscle cell/microfibre mesh constructs, obtained via tissue engineering, as a three-dimensional (3D) platform to study a wireless stimulation system for electrically responsive cells and tissues. Our stimulation strategy exploits the piezoelectric behaviour of some classes of ceramic nanoparticles, such as BNNTs, able to polarize under mechanical stress, e.g. using low-frequency ultrasound (US). In the microfibre scaffolds, C2C12 myoblasts were able to differentiate into viable myotubes and to internalize BNNTs, also upon US irradiation, so as to obtain a nanotech-assisted 3D in vitro model. We then tested our stimulatory system on 2D and 3D cellular models by investigating the expression of connexin 43(Cx43), as a molecule involved in cell crosstalk and mechanotransduction, and myosin, as a myogenic differentiation marker. Cx43 gene expression revealed a marked model dependency. In control samples (without US and/or BNNTs), Cx43 was upregulated under 2D culture conditions (10.78±1.05-fold difference). Interactions with BNNTs increased Cx43 expression in 3D samples. Cx43 mRNA dropped in 2D under the 'BNNTs+US' regimen, while it was best enhanced in 3D samples (3.58±1.05 vs 13.74±1.42-fold difference, p=0.0001). At the protein level, the maximal expressions of Cx43 and myosin were detected in the 3D model. In contrast with the 3D model, in 2D cultures, BNNTs and US exerted a synergistic depletive effect upon myosin synthesis. These findings indicate that model dimensionality and stimulatory regimens can strongly affect the responses of signalling and differentiation molecules, proving the importance of developing proper in vitro platforms for biological modelling.Source: Journal of tissue engineering and regenerative medicine (2014). doi:10.1002/term.1878

Moving medical semeiotics to the digital realm: SEMEOTICONS approach to face signs of cardiometabolic risk
Coppini G., Favilla R., Gastaldelli A., Colantonio S., Marraccini P.
In modern medicine signs derivable from face observation remain an important part of the physical examination that, together with the anamnesis, constitutes the basis for a rational decision-making. Therefore, face semiotics may be considered as a potential source of information for obtaining markers of obesity, metabolomics, cardiovascular homeostasis and psychophysical status. Once properly mapped to computational descriptors, their systematic exploitation is expected allowing the building of effective selfmonitoring systems. In this perspective, in the frame of the FP7 project SEMEOTICONS, the most relevant face signs of cardio-metabolic risk are reviewed and analysed so as to drive their detection, quantification and integration into a virtual individual model useful for cardio-metabolic risk prevention.

Mathematical tools for shape analysis and description
Biasotti S., Falcidieno B., Giorgi D., Spagnuolo M.
This book is a guide for researchers and practitioners to the new frontiers of 3D shape analysis and the complex mathematical tools most methods rely on. The target reader includes students, researchers and professionals with an undergraduate mathematics background, who wish to understand the mathematics behind shape analysis. The authors begin with a quick review of basic concepts in geometry, topology, differential geometry, and proceed to advanced notions of algebraic topology, always keeping an eye on the application of the theory, through examples of shape analysis methods such as 3D segmentation, correspondence, and retrieval. A number of research solutions in the field come from advances in pure and applied mathematics, as well as from the re-reading of classical theories and their adaptation to the discrete setting. In a world where disciplines (fortunately) have blurred boundaries, the authors believe that this guide will help to bridge the distance between theory and practice.DOI: 10.2200/S00588ED1V01Y201407CGR016
