New Stage–Discharge Relationship for Triangular Broad-Crested Weirs
2022
Simple hydraulic structures, such as weirs, allow measuring flow discharge by using the upstream flow depth and a stage–discharge relationship. In this relationship, a discharge coefficient is introduced to correct all the effects neglected in the derivation (viscosity, surface tension, velocity head in the approach channel, flow turbulence, non-uniform velocity profile, and streamline curvature due to weir contraction). In this paper, the dimensional analysis and the incomplete self-similarity theory are used to investigate the outflow process of triangular broad-crested weirs, characterized by different values of the ratio between crest height p and channel width B, and to theoretic…
Automated Detection of Microaneurysms Using Scale-Adapted Blob Analysis and Semi-Supervised Learning
2014
International audience; Despite several attempts, automated detection of microaneurysm (MA) from digital fundus images still remains to be an open issue. This is due to the subtle nature of MAs against the surrounding tissues. In this paper, the microaneurysm detection problem is modeled as finding interest regions or blobs from an image and an automatic local-scale selection technique is presented. Several scale-adapted region descriptors are then introduced to characterize these blob regions. A semi-supervised based learning approach, which requires few manually annotated learning examples, is also proposed to train a classifier to detect true MAs. The developed system is built using only…
Bcl-xL as a Modulator of Senescence and Aging
2021
Many features of aging result from the incapacity of cells to adapt to stress conditions. When cells are overwhelmed by stress, they can undergo senescence to avoid unrestricted growth of damaged cells. Recent findings have proven that cellular senescence is more than that. A specific grade of senescence promotes embryo development, tissue remodeling and wound healing. However, constant stresses and a weakening immune system can lead to senescence chronicity with aging. The accumulation of senescent cells is directly related to tissue dysfunction and age-related pathologies. Centenarians, the most aged individuals, should accumulate senescent cells and suffer from their deleterious effects,…
Understanding the sense of community and continuance intention in virtual communities: The role of commitment and type of community
2019
Virtual communities (VCs) have become essential in current organizations and society, and so their sustainability is a topic of interest for researchers and practitioners. We focus on the sense of virtual community (SoVC) and commitment as relevant antecedents in achieving the success and maintenance of different types of VCs (communities of interest, virtual learning communities, and virtual communities of practice). Specifically, this study examines a moderated mediation model in which the type of virtual community moderates the indirect effect of a SoVC on the intention to continue through the perceived commitment of the users of the VC. The sample consists of 299 members of Virtual comm…
From Sequences to Variables : Rethinking the Relationship between Sequences and Outcomes
2021
Sequence analysis is increasingly used in the social sciences for the holistic analysis of life-course and other longitudinal data. The usual approach is to construct sequences, calculate dissimilarities, group similar sequences with cluster analysis, and use cluster membership as a dependent or independent variable in a regression model. This approach may be problematic, as cluster memberships are assumed to be fixed known characteristics of the subjects in subsequent analyses. Furthermore, it is often more reasonable to assume that individual sequences are mixtures of multiple ideal types rather than equal members of some group. Failing to account for uncertain and mixed memberships may l…
Managing Continuous Digital Service Innovation for Value Co-Creation
2023
Service organizations across various industries are increasingly implementing continuous development methods and practices to transform their digital service innovation and development processes. Consequently, continuous digital service innovation (DSI) has become a way to react to today’s dynamic markets by proposing value to customers quickly while maintaining service quality. However, little is known about how organizations can enable value co-creation (VCC) in their continuous DSI processes. We fill this gap in the literature by focusing on organizational-level continuous DSI processes. Based on findings from 23 industry informants from six Finnish digital service organizations, we pres…

New Gynandromorph Records for Chirocephalus diaphanus (Branchiopoda, Anostraca, Chirocephalidae)
2021
We report and describe new Chirocephalus diaphanus Prévost, 1803 gynandromorphs from Tunisia and review the literature of anostracan gynandromorphy and other, possibly associated, somatic aberrations, with comments on their evolutionary significance. Our material has three specimens that are specifically deformed on the left side of the head.
‘‘This is my home, too’’: Migration, spectrality and hospitality inRoberta Torre’s Sud Side Stori (2000)
2011
The article explores Roberta Torre’s film Sud Side Stori (2000), an extravagant Italian re-vision of Romeo and Juliet set in the Sicilian city of Palermo which displays awareness of the global circulation of the story of the two ‘‘star-crossed lovers’’. In the film, which combines neo-realist cinematographic techniques with the artificial style of the musical, Shakespeare’s young lovers become Toni Giulietto, a lousy local rock singer, and Romea Wacoubo, a beautiful Nigerian prostitute who falls in love with him when she sees him standing on his balcony. Not unlike West Side Story, the inter-racial passion between Toni and Romea exacerbates pre-existing ethnic conflicts. It is opposed not o…
How Geography and Climate Shaped the Genomic Diversity of Italian Local Cattle and Sheep Breeds
2022
International audience; Understanding the relationships among geography, climate, and genetics is increasingly important for animal farming and breeding. In this study, we examine these inter-relationships in the context of local cattle and sheep breeds distributed along the Italian territory. To this aim, we used redundancy analysis on genomic data from previous projects combined with geographical coordinates and corresponding climatic data. The effect of geographic factors (latitude and longitude) was more important in sheep (26.4%) than that in cattle (13.8%). Once geography had been partialled out of analysis, 10.1% of cattle genomic diversity and 13.3% of that of sheep could be ascribe…
