Time-like Proton Form Factors with Initial State Radiation Technique
2022
Electromagnetic form factors are fundamental quantities describing the internal structure of hadrons. They can be measured with scattering processes in the space-like region and annihilation processes in the time-like region. The two regions are connected by crossing symmetry. The measurements of the proton electromagnetic form factors in the time-like region using the initial state radiation technique are reviewed. Recent experimental studies have shown that initial state radiation processes at high luminosity electron-positron colliders can be effectively used to probe the electromagnetic structure of hadrons. The BABAR experiment at the B-factory PEP-II in Stanford and the BESIII experim…
A Time-Non-Homogeneous Double-Ended Queue with Failures and Repairs and Its Continuous Approximation
2018
We consider a time-non-homogeneous double-ended queue subject to catastrophes and repairs. The catastrophes occur according to a non-homogeneous Poisson process and lead the system into a state of failure. Instantaneously, the system is put under repair, such that repair time is governed by a time-varying intensity function. We analyze the transient and the asymptotic behavior of the queueing system. Moreover, we derive a heavy-traffic approximation that allows approximating the state of the systems by a time-non-homogeneous Wiener process subject to jumps to a spurious state (due to catastrophes) and random returns to the zero state (due to repairs). Special attention is devoted to the cas…
Unlocking mixed oxides with unprecedented stoichiometries from heterometallic metalorganic frameworks for the catalytic hydrogenation of CO 2
2021
[EN] Their complex surface chemistry and high oxygen lattice mobilities place mixed-metal oxides among the most important families of materials. Modulation of stoichiometry in mixed-metal oxides has been shown to be a very powerful tool for tuning optical and catalytic properties. However, accessing different stoichiometries is not always synthetically possible. Here, we show that the thermal decomposition of the recently reported metal-organic framework MUV-101(Fe, Ti) results in the formation of carbon-supported titanomaghemite nanoparticles with an unprecedented Fe/Ti ratio close to 2, not achievable by soft-chemistry routes. The resulting titanomaghemite phase displays outstanding catal…
Voltammetric Detection of Lead(II) Using Amide-Cyclam- Functionalized Silica-Modified Carbon Paste Electrodes
2009
2-(4,8,11-Triscarbamoylmethyl-1,4,8,11-tetraazacyclotetradec-1-yl)acetamide (TETAM) derivatives bearing 1, 2, or 4 silylated arms have been synthesized and grafted to the surface of silica gel and ordered mesoporous silica samples. The resulting organic-inorganic hybrids have been incorporated into carbon paste electrodes and applied to the preconcentration electroanalysis of Pb(II). The attractive recognition properties of these cyclam derivatives functionalized with amide pendent groups toward Pb(II) species and the highly porous structure of the adsorbents can be exploited for the selective and sensitive detection of the target analyte. Various parameters affecting the preconcentration a…
Method and Practical Guidelines for Overcoming Enterprise Architecture Adoption Challenges
2017
During the last few years, interest towards Enterprise Architecture (EA) has increased, not least due to anticipated benefits resulting from adopting it. For instance, EA has been argued to provide cost reduction, technology standardisation, process improvement, and strategic differentiation. Despite these benefits, the EA adoption rate and maturity are still low. Consequently, EA benefits are not realised. A major reason hindering the adoption is that EA is not understood correctly. This paper aims for minimising the effect of the lack of understanding EA to adopting EA. Based on the research conducted in Finnish public sector, we propose an improved Enterprise Architecture Adoption Method…
Conjunctions and syntactic complexity: Development of the use of conjunctions in written learner Finnish
2022
Kielitaidon kehittymistä voidaan tutkia mittaamalla oppijankielen sujuvuutta, tarkkuutta ja kompleksisuutta. Kompleksisuus voidaan määritellä oppijankielen monipuolisuudeksi ja kehittyneisyydeksi, mutta syntaktista kompleksisuutta on kansainvälisessä toisen kielen oppimisen tutkimuksessa tyypillisesti mitattu alisteisiin lauserakenteisiin perustuvilla kvantitatiivisilla mittareilla. Tässä artikkelissa syntaktisen kompleksisuuden kehitystä tutkitaan tarkastelemalla rinnastus- ja alistuskonjunktioiden käyttöä suomi toisena kielenä -teksteissä Eurooppalaisen viitekehyksen eri taitotasoilla. Aineistona käytetään Jyväskylän yliopiston Cefling-hankkeen oppijansuomen korpuksen tekstejä. Rinnasteis…
Anonymization as homeomorphic data space transformation for privacy-preserving deep learning
2021
Industry 4.0 is largely data-driven nowadays. Owners of the data, on the one hand, want to get added value from the data by using remote artificial intelligence tools as services, on the other hand, they concern on privacy of their data within external premises. Ideal solution for this challenge would be such anonymization of the data, which makes the data safe in remote servers and, at the same time, leaves the opportunity for the machine learning algorithms to capture useful patterns from the data. In this paper, we take the problem of supervised machine learning with deep feedforward neural nets and provide an anonymization algorithm (based on the homeomorphic data space transformation),…
Firms’ distance to the European productivity frontier
2022
AbstractIn this article we explore the factors contributing to reduce the distance of laggard firms to the European frontier, focusing on institutional factors. To characterize Total Factor Productivity frontier firms within industries for the European Union we use firm level data from AMADEUS for the period 2003–2014. Our findings provide evidence on the importance of governance quality and easiness in getting credit in explaining the distance of laggard firms to the European productivity frontier. We also find that other factors at the country level -tertiary education, R&D stock, and trade openness- and at the firm level -size, age, and capital-intensity- influence the distance of la…
The Need to Approach the Management of the Tourist Destination by the Central and Local Public Authorities in Romania
2017
Abstract In the medium and long term, priorities in the development of tourism aim to develop a complex tourist offer, making the most of the natural and anthropogenic resources existing in connection with the preservation of the environment and the heritage. On the long run, it will contribute to raising the living standards of the population, especially social categories with lower chances of reintegration into the labour market (people made redundant in industry, elderly people etc.). Implementation of the strategy at regional level must be achieved through an active partnership between Romanian public authorities, economic agents and private investors, with the involvement of the federa…
Estudiantes de ciencias jurídicas y trabajos de investigación: análisis de los derechos de propiedad intelectual sobre el TFG, el TFM y la Tesis Doct…
2019
El objetivo de este artículo es analizar los derechos de propiedad intelectual sobre los trabajos elaborados por quienes cursan estudios universitarios, con particular referencia a los TFG, TFM y tesis doctorales que se realizan en el ámbito de la ciencia jurídica. Para ello, en primer lugar, se examina la posibilidad de que el trabajo de investigación sea merecedor de la condición de obra; en segundo lugar, se clarifica la cuestión relativa a la titularidad de los derechos de autor sobre estos trabajos; y, en tercer lugar, se reflexiona en torno a la obligación de dejar las obras en repositorios institucionales de acceso abierto.
