Abstract

We present an analysis of the photometric and spectroscopic dataset of the Type II supernova (SN) 2018ivc in the nearby (10 Mpc) galaxy Messier 77. Thanks to the high cadence of the CHASE survey, we observed the SN rising very rapidly by nearly three magnitudes in five hours (or 18 mag d$^{-1}$). The $r$-band light curve presents four distinct phases: the maximum light is reached in just one day, then a first, rapid linear decline precedes a short-duration plateau. Finally, a long, slower linear decline lasted for one year. Following a radio rebrightening, we detected SN 2018ivc four years after the explosion. The early spectra show a blue, nearly featureless continuum, but the spectra evolve rapidly: after about 10 days a prominent H$\alpha$ line starts to emerge, with a peculiar profile, but the spectra are heavily contaminated by emission lines from the host galaxy. He I lines, namely $\lambda\lambda$5876,7065, are also strong. On top of the former, a strong absorption from the Na I doublet is visible, indicative of a non-negligible internal reddening. From its equivalent width, we derive a lower limit on the host reddening of $A_V\simeq1.5$ mag, while from the Balmer decrement and a match of the $B-V$ colour curve of SN 2018ivc to that of the comparison objects, a host reddening of $A_V\simeq3.0$ mag is obtained. The spectra are similar to those of SNe II, but with strong He lines. Given the peculiar light curve and spectral features, we suggest SN 2018ivc could be a transitional object between the Type IIL and Type IIb SNe classes. In addition, we found signs of interaction with circumstellar medium in the light curve, making SN 2018ivc also an interacting event. Finally, we modelled the early multi-band light curves and photospheric velocity of SN 2018ivc to estimate the explosion and CSM physical parameters., Comment: 19 pages, 22 figures, 3 tables, 3 appendices, accepted for publication on A&A

Abstract

With the aim of improving our knowledge about their nature, we conduct a comparative study on a sample of long-rising Type II supernovae (SNe) resembling SN 1987A. To do so, we deduce various scaling relations from different analytic models of H-rich SNe, discussing their robustness and feasibility. Then we use the best relations in terms of accuracy to infer the SN progenitor's physical properties at the explosion for the selected sample of SN 1987A-like objects, deriving energies of $\sim 0.5$-$15$ foe, radii of $\sim 0.2$-$100 \times 10^{12}$ cm, and ejected masses of $\sim 15$-$55$\msun. Although the sample may be too small to draw any final conclusion, these results suggest that (a) SN 1987A-like objects have parameters at explosion covering a wide range of values; (b) the main parameter determining their distribution is the explosion energy; (c) a high-mass ($\gtrsim 30$\,\Msun), high-energy ($\gtrsim 10$\,foe) tail of events, linked to extended progenitors with radii at explosion $\sim 10^{13}$-$10^{14}$\,cm, challenge standard theories of neutrino-driven core-collapse and stellar evolution. We also find a correlation between the amount of $^{56}$Ni in the ejecta of the SN 1987A-like objects and the spectrophotometric features of the SN at maximum, that may represent a tool for estimating the amount of $^{56}$Ni in the SN ejecta whitout having information on the tail luminosity., Comment: 19 pages, 15 figures, and 2 appendices, accepted for publication on MNRAS

Abstract

Microorganisms, microbiomes, and their products (e.g., enzymes, metabolites, antibiotics, etc.) are key players in the functioning of both natural and anthropized Earth ecosystems; they can be exploited for both research purposes and biotechnological applications, including fighting the big challenges of our era, such as climate change. Culture collections (CCs) and microbial Biological Resource Centres (mBRCs) are repositories of microorganisms that investigate and safeguard biodiversity and facilitate the scientific and industrial communities’ access to microbial strains and related know-how by providing external users with skills and services. Considering this, CCs and mBRCs are pivotal institutions for the valorisation of microorganisms, the safeguarding of life, and the fostering of excellent bioscience. The aim of this review is to present the state-of-the-art of Italian CCs and mBRCs, highlighting strengths, weaknesses, threats, and opportunities. Italy is, indeed, a hotspot of microbial biodiversity with a high rate of endemism and incredible potential, not only for the food and beverage sector (i.e., “Made in Italy” products), where microorganisms can have a beneficial or a spoiling function, but also to guarantee environmental sustainability and foster the bioeconomy through the design of new bioprocesses and products. However, weaknesses, such as the lack of management rules in accordance with international quality standards, are also analysed and ways of overcoming them are discussed. In this context, an overview is given of the Joint Research Unit MIRRI-IT and the European-funded SUS-MIRRI.IT project, which aims to improve the management and sustainability of Italian microbial collections, and serves as a starting point for an innovative revolution in the context of CCs and mBRCs worldwide.

Abstract

The role of the interface potential on the effective mass of charge carriers is elucidated in this work. We develop a new theoretical formalism using a spatially dependent effective mass that is related to the magnitude of the interface potential. Using this formalism we studied Ge quantum dots (QDs) formed by plasma enhanced chemical vapour deposition (PECVD) and co-sputtering (sputter). These samples allowed us to isolate important consequences arising from differences in the interface potential. We found that for a higher interface potential, as in the case of PECVD QDs, there is a larger reduction in the effective mass, which increases the confinement energy with respect to the sputter sample. We further understood the action of O interface states by comparing our results with Ge QDs grown by molecular beam epitaxy. It is found that the O states can suppress the influence of the interface potential. From our theoretical formalism we determine the length scale over which the interface potential influences the effective mass.

6. Development and evaluation of objective measures to predict the speech intelligibility of unilateral and bilateral cochlear implant users in noise and reverberation

Abstract

Algorithms to predict speech intelligibility are useful tools for reliable, low-cost, and repeatable assessment of speech processing technologies, thus replacing costly and time-consuming subjective tests. Of particular practical interest is their application for hearing-impaired listeners, such as cochlear implant (CI) users, where speech enhancement is a possible way to reduce the gap to the higher scores achieved by normal hearing listeners. An additional feature that such measures may possess is the non-intrusiveness, which refers to the capacity of providing a speech intelligibility prediction without the need of a priori information, such as clean reference signals. This thesis includes behavioural and numerical experiments designed to investigate how speech intelligibility in unilateral and bilateral CI users can be predicted via objective measures. It is hypothesised that accurate predictions of speech intelligibility scores can be obtained by incorporation of CI-specific features into the proposed objective measures. In Chap. II, several intrusive measures originally developed for normal hearing listeners are employed to predict the speech intelligibility of unilateral CI users. A non-intrusive measure is also proposed and evaluated against other non-intrusive and intrusive measures, and shown to achieve good performance in noisy and reverberant environments. This measure relies on temporal envelopes and uses filterbanks that were derived for CI users of the Nucleus Freedom. In Chap. III, a non-intrusive measure of the bilateral advantage to speech intelligibility in CI is proposed and evaluated against simulated and publicly available data. As a first step, a non-intrusive model is developed that can predict the binaural advantage to speech intelligibility in normal hearing listeners. Behavioural data was collected in order to validate the accuracy of the model’s predictions. Both the normal hearing and the CI versions of the model measured the contribution of two psychoacoustic phenomena: the better ear effect, and the binaural unmasking. For the CI version of the model, the computation of these two contributions were modified to incorporate known limitations of the electric hearing, such as reduced time and frequency resolution, and the poor sensitivity to interaural time differences. With these modifications, also the CI version of the proposed model yielded accurate predictions of speech intelligibility scores obtained from simulated and subjective data. In Chap. IV, one of the unilateral intrusive measures described in Chap. II is used to optimise the parameters of a filterbank with respect to speech intelligibility in a simulated CI hearing environment. Across the unilateral and bilateral/binaural investigations, it can be concluded that temporal envelope modulations, amongst other factors, play a major role in predicting speech intelligibility for CI users. This is also the case for predictions for normal hearing subjects, and a few models already exist that use alterations in the temporal envelopes domain to predict the effect on speech intelligibility. However, this study shows that not all information employed by current models is necessary for such predictions. Non-intrusive models, such as those described in Chap. I and II, can be as accurate as models that require complete information of target and interferers signals. This means that that these measures could be applied to speech enhancement, providing a quick and inexpensive way to improve current settings in modern CI.

Abstract

Demand for sustainably produced biomass is expected to increase with the need to provide renewable commodities, improve resource security and reduce greenhouse gas emissions in line with COP26 commitments. Studies have demonstrated additional environmental benefits of using perennial biomass crops (PBCs), when produced appropriately, as a feedstock for the growing bioeconomy, including utilisation for bioenergy (with or without carbon capture and storage). PBCs can potentially contribute to Common Agricultural Policy (CAP) (2023-27) objectives provided they are carefully integrated into farming systems and landscapes. Despite significant research and development (R&D) investment over decades in herbaceous and coppiced woody PBCs, deployment has largely stagnated due to social, economic and policy uncertainties. This paper identifies the challenges in creating policies that are acceptable to all actors. Development will need to be informed by measurement, reporting and verification (MRV) of greenhouse gas emissions reductions and other environmental, economic and social metrics. It discusses interlinked issues that must be considered in the expansion of PBC production: (i) available land; (ii) yield potential; (iii) integration into farming systems; (iv) R&D requirements; (v) utilisation options; and (vi) market systems and the socio-economic environment. It makes policy recommendations that would enable greater PBC deployment: (1) incentivise farmers and land managers through specific policy measures, including carbon pricing, to allocate their less productive and less profitable land for uses which deliver demonstrable greenhouse gas reductions; (2) enable greenhouse gas mitigation markets to develop and offer secure contracts for commercial developers of verifiable low-carbon bioenergy and bioproducts; (3) support innovation in biomass utilisation value chains; and (4) continue long-term, strategic R&D and education for positive environmental, economic

Abstract

Background and aim: On January 9, 2020, the World Health Organization (WHO) declared that Chinese health authorities had identified a new coronavirus strain never before isolated in humans, the 2019-nCoV later redefined SARS-CoV-2, that still today represent a public health problem. The present survey started on 10 February 2020 with the aim of a) assessing the risk perception in healthcare workers and young students, following the evolution of attitudes, perception and knowledge over time, b) provide useful information to the general population during survey. Results: A study sample consisting of 4116 Italian in-dividuals of both sexes was enrolled. High levels of risk perception, low perception of self-efficacy and low levels of knowledge scores (24.55 ± 5.76 SD) were obtained indicating the need for continuous population monitoring as well as further communication strategies carried out at institution levels. Conclusion: The results of the present study could help public health authorities in carrying out informative campaigns for general population and could be an important tool in evaluating public knowledge and misperceptions during the management of the COVID-19.

Abstract

The role played by the culture of Design in the context of the planning of public space has evolved over time. In the sphere of Architecture, the 1990s saw the opening of an international debate that encouraged a process of revising the training methods adopted until that time, in favour of new ones capable of placing people – the true users of objects, spaces, and architectures – at the centre. This raised the possibility of breaking down certain disciplinary boundaries in favour of a transdiscipline, the Design of Spaces and Architectures. Spatial Design calls back into question many of the assumptions of the Urban Planning and Architecture of the short century, starting precisely from the relationship between Space and the user. Through recent case studies, this essay proposes an embryonic taxonomy of public space, basing its perspective upon the scientific principle of the recurrence of certain design solutions.

Abstract

Subjective cognitive decline may reflect a dementia prodrome or modifiable risk factor such as sleep disturbance. What is the association between sleep and subjective cognitive decline? Cross-sectional design, from two studies of older adults: the WHICAP in the USA and the HELIAD in Greece. A total of 1,576 WHICAP and 1,456 HELIAD participants, without mild cognitive impairment, dementia or severe depression/anxiety, were included. Participants were mostly women, with 12 (WHICAP) and 8 (HELIAD) mean years of education. Sleep problems were estimated using the Sleep Scale from the Medical Outcomes Study. Subjective cognitive decline was assessed using a structured complaint questionnaire that queries for subjective memory and other cognitive symptoms. Multinomial or logistic regression models were used to examine whether sleep problems were associated with complaints about general cognition, memory, naming, orientation and calculations. Age, sex, education, sleep medication, use of medications affecting cognition, co-morbidities, depression and anxiety were used as co-variates. Objective cognition was also estimated by summarizing neuropsychological performance into composite z-scores. Sleep problems were associated with two or more complaints: WHICAP: β = 1.93 (95% confidence interval: 1.59–2.34), p ≤.0001; HELIAD: β = 1.48 (95% confidence interval: 1.20–1.83), p ≤.0001. Sleep problems were associated with complaints in all the cognitive subcategories, except orientation for the WHICAP. The associations were noted regardless of objective cognition. At any given level of objective cognition, sleep disturbance is accompanied by subjective cognitive impairment. The replicability in two ethnically, genetically and culturally different cohorts adds validity to our results. The results have implications for the correlates, and potential aetiology of subjective cognitive decline, which should be considered in the assessment and treatment of older adults with cognitive complaints. © 2018 European Sleep Research Society

Abstract

Objectives: We studied the prevalence of subjective cognitive decline (SCD) and its determinants in a sample of 1456 cognitively normal Greek adults ≥65 years old. Methods/design: Subjects were evaluated by a multidisciplinary team on their neurological, medical, neuropsychological, and lifestyle profile to reach consensus diagnoses. We investigated various types of SCD, including single-question, general memory decline, specific subjective memory decline based on a list of questions and three types of subjective naming, orientation, and calculation decline. Results: In a single general question about memory decline, 28.0% responded positively. The percentage of our sample that reported at least one complaint related to subjective memory decline was 76.6%. Naming difficulties were also fairly common (26.0%), while specific deficits in orientation (5.4%) and calculations/currency handling (2.6%) were rare. The majority (84.2%) of the population reported subjective deficits in at least one cognitive domain. Genetic predisposition to dementia increased the odds for general memory decline by more than 1.7 times. For each one-unit reduction in the neuropsychological composite score (a mean of memory, executive, language, visuospatial, and attention-speed composite scores), the odds for decline in orientation increased by 40.3%. Depression/anxiety and increased cerebrovascular risk were risk factors for almost all SCD types. Conclusions: SCD regarding memory is more frequent than non-memory decline in the cognitively normal Greek elderly population. Genetic predisposition to dementia, lower cognitive performance, affective symptoms, and increased cerebrovascular risk are associated with prevalent SCD. Further prospective research is needed to improve understanding of the evolution of SCD over time. © 2019 John Wiley & Sons, Ltd.

Abstract

The WHO Global Action Plan on physical activity underlines the binomial "diet and physical activity" for the maintenance of well-being state. The adequate nutritional intake is required for sport and can be achieved by a well-adjusted diet without adding artificial food supplements, whose abuse can even represent a risk and appear as an antechamber of doping. Within a national doping prevention project, a peer education tool was realized in the form of a book and e-book, based on the principle of the Mediterranean Diet as an effective nutritional support in sport and physical activity. This health-literacy book contains recipes from all Italian regions revised for their capability to satisfy sport nutritional needs.

Abstract

The aim of the present study was to evaluate the changes in cervical cancer glucose metabolism for different levels of cellular differentiation. The metabolic activity was measured by standardized uptake value (SUV), SUV normalized to lean body mass, metabolic tumor volume and total lesion glycolysis using fluorine-18 fluorodeoxyglucose positron emission tomography (PET). A correlation study of these values could be used to facilitate therapeutic choice and to improve clinical practice and outcome. This study considered 32 patients with diagnosed cervical cancers, at different International Federation of Gynecology and Obstetrics stages. Glucose metabolism was assessed by PET examination, and histological specimens were examined to determine their initial grade of differentiation. A correlation study of these values was evaluated. Histological examination showed that all cases were of squamous cell carcinoma. Regarding the differentiation of the tumor, 19 well- to moderately-differentiated tumors and 13 poorly-differentiated tumors were determined. Negative findings for correlations between metabolic parameters and initial grade of histological differentiation were found, and considering that histological grade has been shown to have no consistent prognostic value in cervical cancer treatment, PET imaging could play a significant role in cervical cancer prognosis.

Abstract

We examined 7-year change in prevalence of physical (no difficultly performing ADLs), cognitive (Mini Mental State Examination score ≥23) and overall independence (physically and cognitively independent) in LLFS subjects aged 90 ± 6 years. At baseline (n=1442), 84\ 85\% and 71\% were physically, cognitively and overall independent, respectively. After 7-years, 951 (66\ died and 108 (8\ were lost to follow-up. Importantly, 92\% of those lost to follow-up compared to 60.0\% of those who died had baseline independence. Among 7-year survivors, the prevalence of physical, cognitive and overall independence was 74\ 82\% and 61\ respectively. Of those physically, cognitively and overall independent at baseline, 78\ 86\ and 69\% remained independent. Prevalence increased by just 10\% despite the 31\% incidence among 7-year survivors, mainly attributable to high mortality risk among those dependent at baseline. A large proportion of this cohort remained independent, which supports further investigation of factors underlying preserved function at extreme ages.
