Finite groups with all minimal subgroups solitary
2016
We give a complete classification of the finite groups with a unique subgroup of order p for each prime p dividing its order. All the groups considered in this paper will be finite. One of the most fruitful lines in the research in abstract group theory during the last years has been the study of groups in which the members of a certain family of subgroups satisfy a certain subgroup embedding property. The family of the subgroups of prime order (also called minimal subgroups) has attracted the interest of many mathematicians. For example, a well-known result of Itˆo (see [8, Kapitel III, Satz 5.3; 9]) states that a group of odd order with all minimal subgroups in the center is nilpotent. Th…
Performance of the ALICE experiment at the CERN LHC
2014
ALICE is the heavy-ion experiment at the CERN Large Hadron Collider. The experiment continuously took data during the first physics campaign of the machine from fall 2009 until early 2013, using proton and lead-ion beams. In this paper we describe the running environment and the data handling procedures, and discuss the performance of the ALICE detectors and analysis methods for various physics observables.
Cell-cycle control in cell-biomaterial interactions
2000
Current biocompatibility testing involves the demonstration of cell proliferation, which is usually interpreted as a sign of positive biocompatibility when the materials sustain cell proliferation. As the field of biomaterials research is rapidly moving toward tissue-engineered devices and hybrid organs, control of cell function has become a main topic. Cell function, which involves specific differentiation pathways, cannot be separated from cell-cycle control. The study of cell-cycle control is an important extension of routine proliferation assays and has extensive roots in developmental and tumor biology. We studied the expression of the tumour suppressor gene p53 and the proliferation-a…
Measurement of the average shape of longitudinal profiles of cosmic-ray air showers at the Pierre Auger Observatory
2019
The profile of the longitudinal development of showers produced by ultra-high energy cosmic rays carries information related to the interaction properties of the primary particles with atmospheric nuclei. In this work, we present the first measurement of the average shower profile in traversed atmospheric depth at the Pierre Auger Observatory. The shapes of profiles are well reproduced by the Gaisser-Hillas parametrization within the range studied, for E>10 17.8 eV .A detailed analysis of the systematic uncertainties is performed using ten years of data and a full detector simulation. The average shape is quantified using two variables related to the width and asymmetry of the profile, and …

ADI schemes for valuing European options under the Bates model
2018
This paper is concerned with the adaptation of alternating direction implicit (ADI) time discretization schemes for the numerical solution of partial integro-differential equations (PIDEs) with application to the Bates model in finance. Three different adaptations are formulated and their (von Neumann) stability is analyzed. Ample numerical experiments are provided for the Bates PIDE, illustrating the actual stability and convergence behaviour of the three adaptations. peerReviewed
Roll-with-Participation. Il caso di ProMondello a Palermo
2018
This contribution is based on an ongoing experience in Palermo: a participatory process (ProMondello) aimed at producing a master plan. The specificity of ProMondello stems from the fact that the promoters of the process are neither social communities nor local administrations, which so far have only arranged highly questionable and easily exploitable processes. ProMondello is organised by a private stakeholder, the Italo-Belgian Real Estate Company, which has been managing a beach concession for about a century. The case raises several questions: can we have true participation along with such obvious economic interests? What can ensure that citizens’ opinions are not instrumentally used? T…
Overview of development lines of music teaching methods in Finland
2020
This article provides a cross-sectional overview of the evolution of music teaching methods over a 160-year timeline. The objective of the study is limited to examining the mainstream trends in the development of methods, or their manifestations, as well as discussing the causes behind them. The objective is also to investigate the methodical state of the 21st century teaching. The data consists of previous studies, music textbooks and learning diaries of class teacher students (N=79). The analysis of the data is based on analytic-historical and data-driven content analysis. The time period from 1860 to1970 has focused on developing the methods. The participatory and functional methods have…
The inspiration in improvisation : identifying and classifying the approaches to emotion-based musical improvisation
2016
The purpose of this study was to identify the naturally occurring approaches that musicians use to improvise and to analyse the relationships between the approach used, the improviser’s musical experience, and the quality of the resulting improvisation. 16 participants took part in three group improvisation and discussion sessions, and the improvisations of the final session (80 in total) were recorded and rated by experts on emotions- and quality-related aspects. The approaches mentioned by participants in the final session were organised into five distinct categories: technical, musical inspiration, nuanced emotion, visualized scene, and personal experience. Significant negative correlati…
Eight Hypotheses on Technology Use and Psychosocial Wellbeing: A Bicultural Phenomenological Study of Gaming during the COVID-19 Pandemic
2022
AbstractIn this nonconfirmatory qualitative study, we pursued a range of hypotheses regarding how gaming operates in the lives and psychosocial wellbeing of those who actively play videogames during a crisis, such as the COVID-19 pandemic in 2020. Informed by an explorative survey (N = 793), interpretive phenomenological analysis was applied to interview data from actively gaming Chinese (n = 10) and Finnish (n = 10) participants. Our findings demonstrate how the general increase of pandemic-time gaming did not manifest in all player groups, but in some life contexts gaming activity rather decreased along with reformations in subjective meaning hierarchies and values. Ultimately, eight subo…
