Bacteria classification using minimal absent words
2017
Bacteria classification has been deeply investigated with different tools for many purposes, such as early diagnosis, metagenomics, phylogenetics. Classification methods based on ribosomal DNA sequences are considered a reference in this area. We present a new classificatier for bacteria species based on a dissimilarity measure of purely combinatorial nature. This measure is based on the notion of Minimal Absent Words, a combinatorial definition that recently found applications in bioinformatics. We can therefore incorporate this measure into a probabilistic neural network in order to classify bacteria species. Our approach is motivated by the fact that there is a vast literature on the com…

The Impact of Estrogen Decline on Other Noncommunicable Diseases
2017
Estrogens have specific receptors spread out in various systems of the organism. The drastic hormonal fall after menopause may be followed by a series of effects, which may be more or less relevant in the different areas of the organism. The bone constitutes a field that clearly reflects that impact, and postmenopausal osteoporosis has received attention in one ad hoc chapter. The present chapter reviews the impact on functions of the central nervous system, particularly cognition and mood, the skeletal system, specifically osteoarthritis, and the cardiovascular system. The obvious interest of the chapter derives from the importance of the selected systems, which may house highly prevalent …
Reinforcement learning in synthetic gene circuits.
2020
Synthetic gene circuits allow programming in DNA the expression of a phenotype at a given environmental condition. The recent integration of memory systems with gene circuits opens the door to their adaptation to new conditions and their re-programming. This lays the foundation to emulate neuromorphic behaviour and solve complex problems similarly to artificial neural networks. Cellular products such as DNA or proteins can be used to store memory in both digital and analog formats, allowing cells to be turned into living computing devices able to record information regarding their previous states. In particular, synthetic gene circuits with memory can be engineered into living systems to al…
Re-thinking the effects of body size on the study of brain size evolution
2018
Body size correlates with most structural and functional components of an organism’s phenotype – brain size being a prime example of allometric scaling with animal size. Therefore, comparative studies of brain evolution in vertebrates rely on controlling for the scaling effects of body size variation on brain size variation by calculating brain weight/body weight ratios. Differences in the brain size-body size relationship between taxa are usually interpreted as differences in selection acting on the brain or its components, while selection pressures acting on body size, which are among the most prevalent in nature, are rarely acknowledged, leading to conflicting and confusing conclusions. …
Drivers of food waste reduction behaviour in the household context
2021
Studies on the drivers of household consumer engagement in various food waste reduction strategies have been limited. We thus address this gap by developing a research model that utilises two well-known theories, namely, the Theory of Interpersonal Behaviour (TIB) and the Comprehensive Model of Environmental Psychology (CMEP), to explain food waste reduction behaviour in household consumers. The model hypothesises positive associations between emotional, social, and cognitive factors and food waste reduction behaviour, as conceptualised using the 3Rs (reuse, reduce, and recycle). A total of 515 U.S. household consumers participated in the cross-sectional survey. The results suggest that emo…
Do vegetarians feel bad? Examining the association between eating vegetarian and subjective well-being in two representative samples
2020
Abstract Research on the relationship between vegetarianism and subjective well-being (SWB) has produced inconsistent results, which may partly be due to small sample sizes and divergent operationalizations of well-being. For these reasons, the present study aimed to thoroughly examine this association in two large representative samples from Germany (Study 1: N = 12,905, including 665 vegetarians) and Australia (Study 2: N = 15,532, including 383 vegetarians) using a consensual conceptualization of SWB (composed of an affective component, i.e., positive and negative affect, and a cognitive component, i.e., life satisfaction). Results of t-tests showed that vegetarians reported slightly hig…
Could selection tests detect the future performance of descriptive panellists ?
1996
Abstract This paper discusses the appropriateness of screening tests in explaining descriptive panellist performances. It is based on a case study aimed at forming a descriptive panel capable of flavour profiling Camembert cheeses. Eighteen subjects were selected using four sensory tasks evaluating smell sensitivities, olfactory knowledge, odour memory and descriptive ability. Three additional tests were proposed during the 45 hour training to evaluate the recognition memory for odours, the concentration and the verbal creativity abilities. Panellist performances were determined on repeatability and discrimination abilities, and on the complexity of the individual sensory space. Some signif…
