Numerical construction of the density-potential mapping

2018

We demonstrate how a recently developed method Nielsen et al. [Nielsen et al., EPL 101, 33001 (2013)] allows for a comprehensive investigation of time-dependent density functionals in general, and of the exact time-dependent exchange-correlation potential in particular, by presenting the first exact results for two- and three-dimensional multi-electron systems. This method is an explicit realization of the Runge–Gross correspondence, which maps time-dependent densities to their respective potentials, and allows for the exact construction of desired density functionals. We present in detail the numerical requirements that makes this method efficient, stable and precise even for large and rap…

Variation in ω-3 and ω-6 Polyunsaturated Fatty Acids Produced by Different Phytoplankton Taxa at Early and Late Growth Phase

2020

Phytoplankton synthesizes essential ω-3 and ω-6 polyunsaturated fatty acids (PUFA) for consumers in the aquatic food webs. Only certain phytoplankton taxa can synthesize eicosapentaenoic (EPA; 20:5ω3) and docosahexaenoic acid (DHA; 22:6ω3), whereas all phytoplankton taxa can synthesize shorter-chain ω-3 and ω-6 PUFA. Here, we experimentally studied how the proportion, concentration (per DW and cell-specific), and production (µg FA L-1 day-1) of ω-3 and ω-6 PUFA varied among six different phytoplankton main groups (16 freshwater strains) and between exponential and stationary growth phase. EPA and DHA concentrations, as dry weight, were similar among cryptophytes and diatoms. However, Crypto…

Cultivated mushrooms: importance of a multipurpose crop, with special focus on Italian fungiculture

2020

Fungi, organisms of high nutritional value with significant bioactive compound content, are considered to be nutraceuticals, mycotherapeutics, cosmeceuticals and useful for the production of functional foods. Their cultivation allows the sustainable management of agro-industrial wastes and generates good income with low inputs, constituting a good opportunity for the development of economically depressed rural areas. There are also many possible uses for the spent substrate in various sectors. provide an overview of the nutritional value of mushrooms and the cultivation of edible and medicinal mushrooms cultivation and uses in Italy.

Verkkomedian ominaispiirteiden arvo asiakkaalle

2015

Mediat elävät murrosta, joka johtuu digitalisoitumisesta ja internetin yleistymi-sestä. Ongelmana on se, että medioiden perinteiset toimintatavat ja asiakkaan kulutustottumukset eivät sovellu yksiin. Asiakas pystyy saamaan tietoa milloin vain ja mistä vain. Perinteisen median toimintatavat eivät pysty vastaamaan tähän tarpeeseen. Tästä syystä mediat ovat siirtyneet vauhdilla verkkoon tar-joamaan sisältöä. Verkossa ongelmaksi on muodostunut kova kilpailu, joka on pudottanut valtavirtauutisten arvon lähes ilmaiseksi. Vaihtoehtojen ollessa laa-jat asiakkaalle ja medioiden väliset vaihtokustannukset pienet, asiakkaat eivät ole olleet valmiit maksamaan mediatuotteista verkossa. Asiakkaan maksuha…

Tracking oneself for others: communal and self-motivational value of sharing exercise data online

2021

Self-tracking is increasingly popular in recreational sport. Leisure sports practitioners use wearable devices that are connected to online platforms to record, analyse, and share their exercise data. While doing that they interact with a digital system, with themselves, and with peers. This paper examines social-communicative aspects of self-tracking, and the support that these aspects and their associated practices may provide for physical activity behaviour. Data for the study was collected using an online survey and in-depth interviews with Finnish trail runners. The results indicate that sharing exercise data with others on a regular basis can support physical activity behaviour becaus…

Customer Value Framework and Recommendation Intention: The Moderating Role of Customer Characteristics in an Online Travel Community

2019

The aim of this study was to develop and test a model that examined the interactions among the customer value framework, recommendation intention and customer characteristics in an online travel community (OTC). Data were obtained using Amazon Mechanical Turk from 251 members of an OTC as a sample. The partial least squares method was used to analyse the data. We found that all the variables of the customer value framework, including functional value, hedonic value and social value, were positively related to recommendation intention. In addition, using multi-group analyses, the study found differences between how different customer segments perceive each of the value dimensions and their e…

Examining Open Innovation in Science (OIS): what Open Innovation can and cannot offer the science of science

2021

Scholars across disciplines increasingly hear calls for more open andcollaborative approaches to scientific research. The concept of OpenInnovation in Science (OIS) provides a framework that integratesdispersed research efforts aiming to understand the antecedents,contingencies, and consequences of applying open and collaborativeresearch practices. While the OIS framework has already been taken upby science of science scholars, its conceptual underpinnings requirefurther specification. In this essay, we critically examine the OIS conceptand bring to light two key aspects: 1) how OIS builds upon OpenInnovation (OI) research by adopting its attention to boundary-crossingknowledge flows and by…
