Identifying lifetime as one of the key parameters responsible for the low brightness of lanthanide-based OLEDs.
2021
OLEDs based on lanthanide complexes have decisive optical advantages but are hampered by low brightness. Despite the efforts to optimize several parameters such as quantum yield and charge carrier mobility, there seems to be another key parameter that hinders their performances. Experimental data are therefore collected for mixed-ligand europium complexes with bathophenanthroline and different classes of anionic ligands and screened to identify the key parameter responsible for this situation, which turns out to be the long lifetime of their excited states. A broad literature search supports this conclusion, showing that lanthanide complexes are inferior to other classes of OLED emitters of…

Everyday Life Meaningfulness for the Community-Dwelling Oldest Old During the COVID-19 Pandemic
2021
In many countries, the COVID-19 pandemic has led to strong restrictions and changed the everyday lives of older people. In Finland, people aged 70 and over were instructed to stay at home under quarantine-like conditions. Existing studies from other countries have reported increases in negative experiences and symptoms as a result of such restrictions, including psychosocial stress. However, little focus has been given to older people’s experiences of meaningfulness during the pandemic. Using survey and interview data, we ask to what extent have community-dwelling oldest old (80+) experienced meaningfulness during the pandemic, what background factors are associated with meaningfulness and …

2021
The process of design and validation of the content and structure of a tool for the analysis of gender stereotypes applicable to feature films, short films, and television series, both realistic and cartoonish, is presented. The model is called EG_5x4 and consists of five dimensions (corporal, attitudinal, social, affective-sexual, and audiovisual), being novel because of its distribution into four pairs of items per category. The methodological process began with the writing, based on previous instruments on gender stereotypes, of a draft of the items, which were distributed in dimensions and organized in pairs to be able to independently relate each statement to the male and/or female gen…
Design and Study of a Wide-Band Printed Circuit Board Near-Field Probe
2021
Magnetic near-field probes (NFP) represent a suitable tool to measure the magnetic field level from a small electromagnetic interference (EMI) source. This kind of antenna is useful as a magnetic field probe for pre-compliance EMC measurements or debugging tasks since the user can scan a printed circuit board (PCB) looking for locations with strong magnetic fields. When a strong H-field point is found, the designer should check the PCB layout and components placement in that area to detect if this could result in an EMI source. This contribution focuses on analyzing the performance of an easy to build and low-cost H-field NFP designed and manufactured using a standard PCB stack-up. Thereby,…

Computational simulations on the binding and reactivity of a nitrile inhibitor of the SARS-CoV-2 main protease.
2021
We present a detailed computational analysis of the binding mode and reactivity of the novel oral inhibitor PF-07321332 developed against the SARS-CoV-2 3CL protease. Alchemical free energy calculations suggest that positions P3 and P4 could be susceptible to improvement in order to get a larger binding strength. QM/MM simulations unveil the reaction mechanism for covalent inhibition, showing that the nitrile warhead facilitates the recruitment of a water molecule for the proton transfer step.
The Importance of Multilingual Information and Plain English in Response to the COVID-19 Pandemic
2021
Health is a common issue for all human beings. As a consequence, everyone in the world has in some way to cope with the language of medicine. This is true now more than ever due to the global health crisis caused by the current COVID-19 pandemic, which has introduced a great amount of terms, previously mostly used by epidemiologists and statisticians, but which now have entered the daily lexicon of many languages. As the medium of international scientific communication, English is the language of worldwide information about the pandemic, and the main source of terms and expressions for other languages. The impact of the COVID-19 pandemic on English lexicon has been so deep that the Oxford E…

A Review of Key Performance Indicators for Building Flexibility Quantification to Support the Clean Energy Transition
2021
The transition to a sustainable society and a carbon-neutral economy by 2050 requires extensive deployment of renewable energy sources that, due to the aleatority and non-programmability of most of them, may seriously affect the stability of existing power grids. In this context, buildings are increasingly being seen as a potential source of energy flexibility for the power grid. In literature, key performance indicators, allowing different aspects of the load management, are used to investigate buildings’ energy flexibility. The paper reviews existing indicators developed in the context of theoretical, experimental and numerical studies on flexible buildings, outlining the current status a…

Vascular aging in rodent models: contrasting mechanisms driving the female and male vascular senescence
2021
Increasing scientific interest has been directed to sex as a biological and decisive factor on several diseases. Several different mechanisms orchestrate vascular function, as well as vascular dysfunction in cardiovascular and metabolic diseases in males and females. Certain vascular sex differences are present throughout life, while others are more evident before the menopause, suggesting two important and correlated drivers: genetic and hormonal factors. With the increasing life expectancy and aging population, studies on aging-related diseases and aging-related physiological changes have steeply grown and, with them, the use of aging animal models. Mouse and rat models of aging, the most…
A multi‐agent system for itinerary suggestion in smart environments
2021
Abstract Modern smart environments pose several challenges, among which the design of intelligent algorithms aimed to assist the users. When a variety of points of interest are available, for instance, trajectory recommendations are needed to suggest users the most suitable itineraries based on their interests and contextual constraints. Unfortunately, in many cases, these interests must be explicitly requested and their lack causes the so‐called cold‐start problem. Moreover, lengthy travelling distances and excessive crowdedness of specific points of interest make itinerary planning more difficult. To address these aspects, a multi‐agent itinerary suggestion system that aims at assisting t…
In varietate concordia?! Political parties’ digital political marketing in the 2019 European Parliament election campaign
2021
This article provides the first comprehensive analysis of how parties across 28 countries use digital political marketing on Facebook by drawing on the example of the 2019 European Parliament election. We introduce a theoretical model of political Facebook marketing and compare the paid media activity (sponsored posts, ads) of 186 parties to their owned media (posts) and earned media (user reactions, comments, shares). Our results concerning cross-country patterns indicate that differences in European parties’ paid media activity exist and only a few parties leverage sophisticated targeting strategies. Regarding temporal dynamics, we find that paid media is used to supplement owned media du…

The leaders' place in the Westminster system
2021
International audience; This paper aims at examining to what extent breaking the rules constitutes a strategy for leaders to “find their place” in the Westminster system during parliamentary debates and more specifically during PMQs. In the context of Westminster politics, place can be understood in several ways. Place can be undertsood in its dialectical relationship between the physical and political dimension with parties occupying a specific place in the Commons placing them on the political spectrum from right to left. More interestingly, Westminster in a sort of metonymical process embodies UK’s politics. The leaders of major parties participate in the debates in the House of Commons.…
The pricing capability lifecycle of digital innovations
2021
The pricing capability provides a basis for firms’ competitive advantage. However, to date, the literature has not investigated how this capability forms, develops, and matures. In this study, we define the pricing capability as a dynamic capability consisting of three operational building blocks (tools and data, human and relational resources, and processes, routines, and mechanisms) as well as two dynamic capability building blocks (alertness and responsiveness, and value-based strategic thinking). Furthermore, we propose the pricing capability lifecycle of digital innovations that incorporates insights of the dynamic capabilities view (DCV). Based on a longitudinal multi-case study of fi…

BIODIVERSITA’ DELLE COMUNITA’ BATTERICHE IN UN SUOLO SOTTOPOSTO A BIORISANAMENTO IN MICROCOSMO
2021
Gli idrocarburi (HC) sono uno dei principali inquinanti ambientali. Una tecnologia promettente per il trattamento di siti contaminati si basa sulla biodegradazione degli inquinanti da parte di popolazioni microbiche capaci di utilizzare HC come fonte di carbonio ed energia (Biorisanamento). La necessità di risanare siti contaminati richiede da una parte la caratterizzazione delle comunità microbiche coinvolte nella biodegradazione, dall’altra lo sviluppo di interventi volti a migliorare il potenziale metabolico dei microrganismi degradatori. La nostra attività di ricerca ha avuto come obiettivo quello di caratterizzare e analizzare la biodiversità di comunità microbiche di un suolo contamin…

This article discusses the meaning of sustainability in this field of policy and practice in a medium-size city in Finland. It focuses on services for unemployed people and the role of social work. The paper aims to contribute to the knowledge base on sustainable welfare in a Nordic context and on ecosocial work in Finland. It is structured by two main questions. 1) How is ‘sustainability’ perceived and interpreted in the context of services for unemployed people? 2) What potential for eco-social polici…
DIVERSITÀ BATTERICA DI SUOLI MEDITERRANEI SOGGETTI A DESERTIFICAZIONE
2021
Siccità e fenomeni meteorologici estremi contribuiscono al degrado dei suoli mediterranei semi-aridi causando erosione, compattazione, salinizzazione, riduzione della sostanza organica e perdita di biodiversità, con conseguenze negative per l’agricoltura e l’ambiente. Gli effetti dei cambiamenti climatici in atto sono esacerbati da pratiche agronomiche insostenibili e pascolo incontrollato che concorrono alla desertificazione dei suoli. E’ fondamentale monitorare la qualità dei suoli semi-aridi per prevenirne il degrado irreversibile. Tale monitoraggio viene usualmente condotto mediante i tradizionali indicatori chimico-fisici di qualità del suolo. Ancora raramente vengono utilizzati indica…
Transpiration and Water Use of an Irrigated Traditional Olive Grove with Sap-Flow Observations and the FAO56 Dual Crop Coefficient Approach
2021
The SIMDualKc model was applied to evaluate the crop water use and the crop coefficient (Kc) of an irrigated olive grove (Olea europaea L.) located in Sicily, Italy, using experimental data collected from two crop seasons. The model applies the FAO56 dual Kc approach to compute the actual crop evapotranspiration (ETc act) and its components, i.e., the actual tree transpiration (Tc act), obtained through the basal crop coefficient (Kcb), and soil evaporation according to an evaporation coefficient (Ke). Model calibration was performed by minimizing the difference between the predicted Tc act and the observed daily tree transpiration measured with sap flow instrumentation (TSF field) acquired…
Bioactive compounds from brown algae inhabiting the north-western Mediterranean Sea
2021
Marine algae produce a great amount of secondary metabolites (e.g. terpenoids, fatty acids, steroids, polysaccharides and polyphenols) to face environmental stressors they are exposed to, but also to defend themselves from biological pressures such as competitors, pathogens, grazers and epiphytes. Over the last decade, secondary metabolites isolated from brown algae and phenolic compounds, in particular, are receiving increasing attention due to their putative ecological roles, and several biological properties. Brown fucoid algae of the genus Cystoseira sensu latu (Sargassaceae) and Dictyotaceae produce a wide variety of secondary metabolites which have been investigated mainly for their d…

Analysis of different geometrical features to achieve close-to-bone stiffness material properties in medical device: A feasibility numerical study
2021
Background and objective: In orthopedic medical devices, elasto-plastic behavior differences between bone and metallic materials could lead to mechanical issues at the bone-implant interface, as stress shielding. Those issue are mainly related to knee and hip arthroplasty, and they could be responsible for implant failure. To reduce mismatching-related adverse events between bone and prosthesis mechanical properties, modifying the implant's internal geometry varying the bulk stiffness and density could be the right approach. Therefore, this feasibility study aims to assess which in-body gap geometry improves, by reducing, the bulk stiffness. Methods: Using five finite element models, a unia…
