Tidskriftsartikel (refereegranskat)abstract
- ESSνSB is a design study for a next-generation long-baseline neutrino experiment that aims at the precise measurement of the CP-violating phase, δCP, in the leptonic sector at the second oscillation maximum. The conceptual design report published from the first phase of the project showed that after 10 years of data taking, more than 70% of the possible δCP range will be covered with 5σ C.L. to reject the no-CP-violation hypothesis. The expected value of δCP precision is smaller than 8◦ for all δCP values. The next phase of the project, the ESSνSB+, aims at using the intense muon flux produced together with neutrinos to measure the neutrino-nucleus cross-section, the dominant term of the systematic uncertainty, in the energy range of 0.2–0.6 GeV, using a Low Energy neutrinos from STORed Muons (LEnuSTORM) and a Low Energy Monitored Neutrino Beam (LEMNB) facilities.

Study of nonstandard interactions mediated by a scalar field at the ESSnuSB experiment

Tidskriftsartikel (refereegranskat)abstract
- In this paper, we study scalar mediator induced nonstandard interactions (SNSIs) in the context of the ESSnuSB experiment. In particular, we study the capability of ESSnuSB to put bounds on the SNSI parameters and also study the impact of SNSIs in the measurement of the leptonic CP phase δCP. Existence of SNSIs modifies the neutrino mass matrix and this modification can be expressed in terms of three diagonal real parameters (ηee, ημμ, and ηττ) and three off-diagonal complex parameters (ηeμ, ηeτ, and ημτ). Our study shows that the upper bounds on the parameters ημμ and ηττ depend upon how Δm312 is minimized in the theory. However, this is not the case when one tries to measure the impact of SNSIs on δCP. Further, we show that the CP sensitivity of ESSnuSB can be completely lost for certain values of ηee and ημτ for which the appearance channel probability becomes independent of δCP.

Resource profile and user guide of the Polygenic Index Repository

Tidskriftsartikel (refereegranskat)abstract
- Polygenic indexes (PGIs) are DNA-based predictors. Their value for research in many scientific disciplines is growing rapidly. As a resource for researchers, we used a consistent methodology to construct PGIs for 47 phenotypes in 11 datasets. To maximize the PGIs’ prediction accuracies, we constructed them using genome-wide association studies—some not previously published—from multiple data sources, including 23andMe and UK Biobank. We present a theoretical framework to help interpret analyses involving PGIs. A key insight is that a PGI can be understood as an unbiased but noisy measure of a latent variable we call the ‘additive SNP factor’. Regressions in which the true regressor is this factor but the PGI is used as its proxy therefore suffer from errors-in-variables bias. We derive an estimator that corrects for the bias, illustrate the correction, and make a Python tool for implementing it publicly available. © 2021, The Author(s), under exclusive licence to Springer Nature Limited.

Trade in Services in the New Century
- 2019
-
Bok (refereegranskat)abstract
- Concerns have been raised about the potential adverse effects of liberalizing trade in services under the GATS framework on equity, costs, distribution, availability of services and sovereignty of governments in defining their national objectives. These concerns have been voiced in poor countries in case of such social service sectors as health and education. Critics have stressed the need for an environment that is conducive to both efficiency and social development.

Institutions, growth and governance in the third world
- 2023
-
Bok (refereegranskat)abstract
- Recent research has used the work of Douglas North as the foundation on which the case of institutions as ultimate driver of development could be built.North describes institutions as 'the humanly devised constraints that shape human interaction'. These arepowerful metaphors for us who are accustomed to think in terms of'constrained maximization' as the rule guiding personal actions. This book explores complex issues such as inatitutions and geography, new Kaldor facts, institutions and endowments, institutions and culture, governance and such.

International Monetary Interdependence in the New Century
- 2019
-
Bok (refereegranskat)abstract
- Even though each country is trying to follow its own monetary policy, it is affecting other countries which have, trade and capital flow links with each other. hence, the monetary policy of each individual country has an impact at the global level. The study analyses this interdependence. More specifically, this book discusses the emerging international financial structure, the liquidity crises, financial globalization, monetary policies and financial stability and few other related and relevant issues.
