Multimodal music information processing and retrieval: survey and future challenges
Towards improving the performance in various music information processing
tasks, recent studies exploit different modalities able to capture diverse
aspects of music. Such modalities include audio recordings, symbolic music
scores, mid-level representations, motion, and gestural data, video recordings,
editorial or cultural tags, lyrics and album cover arts. This paper critically
reviews the various approaches adopted in Music Information Processing and
Retrieval and highlights how multimodal algorithms can help Music Computing
applications. First, we categorize the related literature based on the
application they address. Subsequently, we analyze existing information fusion
approaches, and we conclude with the set of challenges that Music Information
Retrieval and Sound and Music Computing research communities should focus in
the next years
Graph based representation of the music symbolic level. A music information retrieval application
In this work, a new music symbolic level representation system is described. It has been tested in two information retrieval tasks concerning similarity between segments of music and genre detection of a given segment. It could include both harmonic and contrapuntal informations. Moreover, a new large dataset consisting of more than 5000 leadsheets is presented, with meta informations taken from different web databases, including author information, year of first performance, lyrics, genre, etc.ope
The role of autophagy in liver epithelial cells and its Impact on systemic homeostasis
Autophagy plays a role in several physiological and pathological processes as it controls
the turnover rate of cellular components and influences cellular homeostasis. The liver plays a
central role in controlling organismsâ metabolism, regulating glucose storage, plasma proteins and
bile synthesis and the removal of toxic substances. Liver functions are particularly sensitive to
autophagy modulation. In this review we summarize studies investigating how autophagy
influences the hepatic metabolism, focusing on fat accumulation and lipids turnover. We also
describe how autophagy affects bile production and the scavenger function within the complex
homeostasis of the liver. We underline the role of hepatic autophagy in counteracting the metabolic
syndrome and the associated cardiovascular risk. Finally, we highlight recent reports demonstrating
how the autophagy occurring within the liver may affect skeletal muscle homeostasis as well as
different extrahepatic solid tumors, such as melanoma
Neonatal Encephalopathy and SIADH during RSV Infection
Abstract
ObjectiveâThis report discusses the neurological involvement in respiratory syncytial virus (RSV) infection in neonates.
Study DesignâWe present a case report of a 2-month-old infant affected by a bronchiolitis RSV-positive, with syndrome of inappropriate antidiuretic hormone secretion (SIADH) correlated seizure and encephalopathy.
ResultsâRSV infection can be associated as a serious disease in newborns involving the central nervous system (CNS) and causing seizures or acute encephalopathy. RSV may be also responsible for SIADH and seizures associated with hyponatremia. The RSV related encephalopathy could be caused by different mechanisms, such as direct viral invasion of the CNS or by indirect mechanism mediated by inflammatory cytokines. In addition, it can be favored by severe hyponatremia and SIADH that can cause cerebral edema. Some studies highlight that this virus-related encephalopathy lead to sudden infant death syndrome.
ConclusionâIn presence of neurological involvement during RSV-infection must be taken in consideration to performing instrumental test to detect cerebral edema. In addiction could be useful to dose inflammatory cytokines, and to consider the immune-modulatory therapy
Optimizing Feature Extraction for Symbolic Music
This paper presents a comprehensive investigation of existing feature
extraction tools for symbolic music and contrasts their performance to
determine the set of features that best characterizes the musical style of a
given music score. In this regard, we propose a novel feature extraction tool,
named musif, and evaluate its efficacy on various repertoires and file formats,
including MIDI, MusicXML, and **kern. Musif approximates existing tools such as
jSymbolic and music21 in terms of computational efficiency while attempting to
enhance the usability for custom feature development. The proposed tool also
enhances classification accuracy when combined with other sets of features. We
demonstrate the contribution of each set of features and the computational
resources they require. Our findings indicate that the optimal tool for feature
extraction is a combination of the best features from each tool rather than
those of a single one. To facilitate future research in music information
retrieval, we release the source code of the tool and benchmarks.Comment: Published at ISMIR 202
Contemporary Architecture in Genoa since 1945âKnowledge and Use through Geoservices for the Citizen
The paper illustrates the enhancement of knowledge of architecture from 1945 onwards in Genoa by means of the publication on the Geoportal of the Municipality, which was developed with open-source systems, of a proper dataset and tools for digital storytelling for citizens. The implementation on the municipal Geoportal of a section called âContemporary Architecture from 1945 onwards in Genoaâ was made possible through collaboration between the University of Genoa Architecture and Design Department (DAD) and the Municipality of Genoa Office for Geographical Information Systems. The data related to the buildings in the Municipality of Genoa were extracted from a previous study about contemporary architecture in Liguria carried out by DAD. The case study introduced two tools for the promotion and enhancement of knowledge of such architecture, a map on which the buildings are located and associated with an information form and geostories with in-depth information on selected buildings, the latter of which can be sorted based on thematic itineraries or by author. The use of integrated services contributes to the competitiveness and sustainability of the city, raising citizensâ awareness of the value of the architecture of the second half of the 20th century and thus activating conservation processes as advocated in the Sustainable Development Goals of the United Nations General Assembly
