Integrating wearable haptics and obstacle avoidance for the visually impaired in indoor navigation: a user-centered approach
Barontini F, Catalano Mg, Pallottino L, Leporini B, Bianchi M
Recently, in the attempt to increase blind people autonomy and improve their quality of life, a lot of effort has been devoted to develop technological travel aids. These systems can surrogate spatial information about the environment and deliver it to end-users through sensory substitution (auditory, haptic). However, despite the promising research outcomes, these solutions have met scarce acceptance in real-world. Often, this is also due to the limited involvement of real end users in the conceptual and design phases. In this manuscript, we propose a novel indoor navigation system based on wearable haptic technologies. All the developmental phases were driven by continuous feedback from visually impaired persons. The proposed travel aid system consists of a RGB-D camera, a processing unit to compute visual information for obstacle avoidance, and a wearable device, which can provide normal and tangential force cues for guidance in an unknown indoor environment. Experiments with blindfolded subjects and visually impaired participants show that our system could be an effective support during indoor navigation, and a viable tool for training blind people to the usage of travel aids.Source: IEEE TRANSACTIONS ON HAPTICS, vol. 14 (issue 1), pp. 109-122

Effects of acute and sub-acute hypobaric hypoxia on oxidative stress: a field study in the Alps
Mrakicsposta S, Gussoni M, Dellanoce C, Marzorati M, Montorsi M, Rasica L, Pratali L, D'Angelo G, Martinelli M, Bastiani L, Di Natale L, Vezzoli A
PurposeHigh altitude results in lower barometric pressure and hence partial pressure of O2 decrease can lead to several molecular and cellular changes, such as generation of reactive oxygen species (ROS). Electron Paramagnetic Resonance technique was adopted in the field, to evaluate the effects of acute and sub-acute hypobaric hypoxia (HH) on ROS production by micro-invasive method. Biological biomarkers, indicators of oxidative stress, renal function and inflammation were investigated too.MethodsFourteen lowlander subjects (mean age 27.3 ± 5.9 years) were exposed to HH at 3269 m s.l. ROS production, related oxidative damage to cellular components, systemic inflammatory response and renal function were determined through blood and urine profile performed at 1st, 2nd, 4th, 7th, and 14th days during sojourn.ResultsKinetics of changes during HH exposition showed out significant (range p < 0.05-0.0001) increases that at max corresponds to 38% for ROS production rate, 140% for protein carbonyl, 44% for lipid peroxidation, 42% for DNA damage, 200% for inflammatory cytokines and modifications in renal function (assessed by neopterin concentration: 48%). Conversely, antioxidant capacity significantly (p < 0.0001) decreased - 17% at max.ConclusionThis 14 days in-field study describes changes of oxidative-stress biomarkers during HH exposure in lowlanders. The results show an overproduction of ROS and consequent oxidative damage to protein, lipids and DNA with a decrease in antioxidant capacity and the involvement of inflammatory status and a transient renal dysfunction. Exposure at high altitude induces a hypoxic condition during acute and sub-acute phases accompanied by molecular adaptation mechanism indicating acclimatization.Source: EUROPEAN JOURNAL OF APPLIED PHYSIOLOGY (PRINT), vol. 121, pp. 297-306

Digital safeguard of laminated historical manuscripts: the treatise "Poem in Rajaz on medicine" as a case study
Del Grosso Am, Fassi Fihri D, El Mohajir M, Nahli O, Tonazzini A
In this paper, we analyze and discuss the characteristics of a system for the effective digital preservation and fruition of historical manuscripts degraded by the process of lamination. As a case study, we will make reference to the "Poem in Rajaz on medicine", written by Abubacer in the XII century, and conserved in the Al Quaraouiyine Library located in Fez, Morocco. The conceived system should have at least four main functionalities: image acquisition (i.e. digitization), image enhancement, text encoding, and linguistic analysis. Based on the evaluation of the manuscript damages, the acquisition set up should be designed in such a way to be able to avoid reflections as much as possible. Suitable digital image processing techniques should also be devised to correct the residual degradations and enhance the text for an easier legibility. Finally, semi-automatic transcription, scholarly encoding and linguistic analysis, to be performed on the virtually restored pages, should adapt existing tools to the specificity of the primary source writing system and language. The feasibility study for the realization of such a system is of general utility, in that it can provide guidelines for the digitization, the enhancement and the text encoding of the many laminated manuscripts conserved in other historical archives. On the other hand, from the cultural heritage point of view, the experimentation on the "Poem in Rajaz on medicine" could foster the systematic philological and ontological study of a unique piece of our documental heritage: the longest poem of medieval Islamic medical literature.DOI: 10.1109/cist49399.2021.9357192

Using random forests to classify vessels from naive geometrical features
Salerno E
This report is concerned with the application of Random Forest classification methods to the identification of ship types in moderate-resolution SAR images. After a brief presentation of the theory and and the features of this class of methods, we select an R package useful to train, test and execute the classifier. Some experiments are then reported using naive geometrical features extracted from a few thousands of targets in the OpenSARShip data set. All the ship chips extracted are derived from IW GRD Sentinel 1 C-band SAR images, accompanied by AIS and MarineTraffic ground-truth data. The ideal performance of this classifier is evaluated through the standard classification indices, with respect to the ship types that are sufficiently represented in the subsets considered.

PsicoTableau: sperimentazione artistica sui livelli di attivazione e valenza emotiva attuata mediante sensori biomedici
Ratto C., Magrini M.
Questo lavoro di tesi consiste nello studio e nella realizzazione di un'installazione audiovisiva reattiva allo stato emotivo del visitatore. Sebbene il lavoro si inserisca in un panorama ormai ben consolidato come quello delle arti elettroniche interattive, la particolare modalità di interazione uomo-macchina che utilizza la caratterizza sufficientemente da renderla sicuramente non comune. Laddove la maggior parte delle opere interattive presuppone di utilizzare la presenza fisica e la gestualità per attivare e/o controllare i contenuti, siano essi audio video o cinetici, in questo lavoro si è scelto di utilizzare lo stato emotivo come impalpabile catalizzatore dei media. La filosofia adottata sposta quindi il valore estetico dell'opera dagli aspetti più "retinici" a quelli più concettuali: è il meccanismo in sé che costituisce l'operazione estetica, non (solo) i risultati/output che produce e controlla.

La stella di Deotisalvi
Tarabella L
Deotisalvi è l'Architetto del secolo d'oro, il XII. Della sua vita non si sa niente. Forse veniva dall'Oriente. Forse era un frate. Di lui sono rimasti i suoi monumenti e, nelle parole di Silvano Burgalassi, i monumenti parlano di per sé ... perché ci sono. Questo è un racconto del tutto fantasioso sulla vita di Deotisalvi ispirato dalla geometria dei suoi monumenti. I monumenti della Piazza sono la mente e la vita artistica di Deotisalvi: una mente ed una vita spirituale e geometrica. E neanche matematica (caso mai aritmetica) ma geometrica.Perché la matematica come la pensiamo, la conosciamo e la utilizziamo ora all'epoca non esisteva. La geometria è nella Natura.La matematica è nella mente dell'uomo. La geometria è il collegamento tra l'uomo e la Natura.

Technical report on the development and interpretation of convolutional neural networks for the classification of multiparametric MRI images on unbalanced datasets. Case study: prostate cancer
Pachetti E, Colantonio S
This report summarized the activities carried out to define, train and validate Deep Learning models for the classification of medical imaging data. The issue of unbalanced datasets was faced by applying some data augmentation techniques, based on transformation of the original images. Such techniques were compared to verify their impact in a frame where object morphology is relevant. Multimodal deep learning models were defined to exploit the information contained in heterogeneous imaging data and cope with data distribution imbalance. To verify the inner functioning of the deep learning models, the LIME algorithm was applied, thus checking that the regions that contribute to the classification were the real meaningful ones. The case study used to was the categorization of prostate cancer aggressiveness based on Magnetic Resonance Imaging (MRI) data. The aggressiveness was determined, as a ground truth, via tissue biopsy and expressed with a score from 2 to 10 known as Gleason Score, which is obtained as the sum of two values, each one from 1 to 5, associated with the two most common patterns in the tumor tissue histological sample.

Learning topology: bridging computational topology and machine learning
Moroni D, Pascali Ma
Topology is a classical branch of mathematics, born essentially from Euler's studies in the XVII century, which deals with the abstract notion of shape and geometry. Last decades were characterised by a renewed interest in topology and topology-based tools, due to the birth of computational topology and Topological Data Analysis (TDA). A large and novel family of methods and algorithms computing topological features and descriptors (e.g. persistent homology) have proved to be effective tools for the analysis of graphs, 3d objects, 2D images, and even heterogeneous datasets. This survey is intended to be a concise but complete compendium that, offering the essential basic references, allows you to orient yourself among the recent advances in TDA and its applications, with an eye to those related to machine learning and deep learning.DOI: 10.1007/978-3-030-68821-9_20
