Multinucleon transfer reactions: an overview of recent results
2012
Large acceptance magnetic spectrometers, such as PRISMA installed at Laboratori Nazionali di Legnaro, gave a further boost to the renewed interest for multinucleon transfer reactions in the last decade. The large solid angles of these devices and the high resolving powers of their detection systems allowed to investigate the transfer process around and well below the Coulomb barrier and to perform nuclear structure studies in several mass regions of the nuclide chart when coupled with large γ-ray arrays such as CLARA. Selected results obtained with the PRISMA-CLARA set-up in odd argon isotopes populated by using the multinucleon transfer process and in sub- barrier transfer measurements are…
Frequent coinfection of cells explains functional in vivo complementation between cytomegalovirus variants in the multiply infected host.
2005
In contrast to many other virus infections, primary cytomegalovirus (CMV) infection does not fully protect against reinfection. Accordingly, clinical data have revealed a coexistence of multiple human CMV variants/ strains in individual patients. Notably, the phenomenon of multiple infection was found to correlate with increased virus load and severity of CMV disease. Although of obvious medical relevance, the mechanism underlying this correlation is unknown. A weak immune response in an individual could be responsible for a more severe disease and for multiple infections. Alternatively, synergistic contributions of variants that differ in their biological properties can lead to qualitative…
Tras un denário imitativo de Turiasu hallado en Vila Real (Portugal)
2017
El artículo da a conocer el hallazgo aislado de un importante denario procedente del norte de Portugal. La moneda se caracteriza por ser forrada o falsa de época y por presentar un arte imitativo de Turiasu. También se ofrecen algunas reflexiones y nuevo material numismático en torno a los denarios forrados, imitativos, híbridos e incusos.
Riflessioni e traiettorie di ricerca interdisciplinari sulla transizione digitale
2022
The contribution introduces the topic covered by vol. 12 of AGATHÓN through essays, studies, research and projects on Innovability©® | Digital Transition to investigate the current widespread transformation that unites dichotomies (analogue and digital), enhances oxymorons (artificial intelligence), creates paradoxes (materiality of the intangible), while indiscriminately involving architecture, humanities and social sciences, anthropology, sociology, ecology, biology, physical-mathematical sciences and neurosciences, with impacts that – while already visible today and accelerated in part by the extraordinary global health emergency – will become even more evident in the medium and long ter…
In situ recordings of large gelatinous spheres from NE Atlantic, and the first genetic confirmation of egg mass of Illex coindetii (Vérany, 1839) (Ce…
2021
AbstractIn total, 90 gelatinous spheres, averaging one meter in diameter, have been recorded from ~ 1985 to 2019 from the NE Atlantic Ocean, including the Mediterranean Sea, using citizen science. More than 50% had a dark streak through center. They were recorded from the surface to ~ 60–70 m depth, mainly neutrally buoyant, in temperatures between 8 and 24°C. Lack of tissue samples has until now, prohibited confirmation of species. However, in 2019 scuba divers secured four tissue samples from the Norwegian coast. In the present study, DNA analysis using COI confirms species identity as the ommastrephid broadtail shortfin squid Illex coindetii (Vérany, 1839); these are the first confirmed …
Research data sharing in Spain: Exploring determinants, practices, and perceptions
2020
This work provides an overview of a Spanish survey on research data, which was carried out within the framework of the project Datasea at the beginning of 2015. It is covered by the objectives of sustainable development (goal 9) to support the research. The purpose of the study was to identify the habits and current experiences of Spanish researchers in the health sciences in relation to the management and sharing of raw research data. Method: An electronic questionnaire composed of 40 questions divided into three blocks was designed. The three Section s contained questions on the following aspects: (A) personal information
Terms of trade, catch-up, and home-market effect: The example of Japan
2007
Abstract This paper explores theoretically and empirically the medium- and long-run relation of the terms of trade (ratio of traded goods prices) and economic growth of a pair of countries—one of which experiences a major catch-up process towards the other. Two theoretical interdependencies between the terms of trade and economic growth are offered: the home-market effect and the productivity-shock effect. These two effects are tested against each other in a cointegration analysis on data for Japan and the US from 1971 until 1997. Income is cointegrated with the terms of trade. The relevant empirical channel is the home-market effect. However, financial-market effects appear also to be rele…
Kriptovalūtas un to regulējums Eiropas Savienībā
2019
Līdz ar kriptovalūtas straujo attīstību pasaule un to šobrīdejo popolaritāti Eiropā, tās nelikumīgo izmantošanu, pieeaug kriptovalūtas negatīvā slava un Eiropas Savienības valstu negatīvā nostāja pret šādu, mums nepieņemamu, valūtas veidu, aizvien biežāk tiek sabiedrībā apspriests jautājums vai šādai valūtai nebūtu pienācis īstais laiks iegūt regulējumu, kas pēdējā gada laikā ir aktīvi apspriests arī no Eiropas Savienības valstu puses. Neskatoties uz to, ka jau kādu laiku šī valūta ir pastāvējusi, izpratne par to un kam tā ir radīta, ir ļoti maza. Eiropas Savienībai ir izstrādāts regulējums, kurš min kriptovalūtas, taču tas īsti tās neregulē. Tieši šī iemesla dēļ darba nosaukums ir “Kriptov…
Finanšu burbuļu izveide kriptoaktīvu tirgū
2022
Bakalaura darbā tiek aplūkots Bitcoin kriptovalūtas kapitalizācijas pamatojums, kā arī analizēts tās kriptovalūtas cenas straujais kāpums laika posmā no 2013.g. līdz 2022.g. Mērķis ir pārliecināties, par finanšu burbuļa pastāvēšanas iespējamību Bitcoin kriptovalūtas tirgū. Aplūkojot tirgus statistiskos datus, kā arī veicot Bitcoin kriptovalūtas pielietošanas un izmantošanas analīzi, to savstarpējo salīdzinājumu ar citām valūtām, darbā tiek uzrādītas Bitcoin kriptovalūtas nepilnības. Turklāt, Bitcoin kriptovalūtas tirgus cenas izpētei darbā tiek izmantota DFA (angl. detrended fluctuation analysis) matemātiskā metode, pēc kuras tika konstatēta Bitcoin tirgus cenas homogenitāte, kas liecina pa…
Experimental investigations of the hypernucleus $_Λ^4$H
2015
International audience; Negatively charged pions from two-body decays of stopped _Lambda^4H hypernuclei were studied in 2012 at the Mainz Microtron MAMI, Germany. The momenta of the decay-pions were measured with unprecedented precision by using high-resolution magnetic spectrometers. A challenge of the experiment was the tagging of kaons from associated K^+∧ production off a Be target at very forward angles. In the year 2014, this experiment was continued with a better control of the systematic uncertainties, with better suppression of coincident and random background, improved particle identification, and with higher luminosities. Another key point of the progress was the improvemen…
