Role of conditional probability in multiscale stationary markovian processes.
2010
The aim of the paper is to understand how the inclusion of more and more time-scales into a stochastic stationary Markovian process affects its conditional probability. To this end, we consider two Gaussian processes: (i) a short-range correlated process with an infinite set of time-scales bounded from below, and (ii) a power-law correlated process with an infinite and unbounded set of time-scales. For these processes we investigate the equal position conditional probability P(x,t|x,0) and the mean First Passage Time T(L). The function P(x,t|x,0) can be considered as a proxy of the persistence, i.e. the fact that when a process reaches a position x then it spends some time around that posit…

From canon to chaos management: blogging as a learning tool in a modern Finnish literature course
2015
This article is based on the teaching experiment implemented in summer 2013 in a modern Finnish literature course organised by the Centre for International Mobility (CIMO) and the University of Jyvaskyla Language Centre. In order to break away from the traditional conception of literature and text, students’ independent blogging was chosen as the final course assignment instead of a traditional final project. Our aim has been to determine what blogging as an activity can add to second-language learning (i.e. learning the language in a country where it is spoken as a native language) in the context of modern Finnish literature. Our special interest is how new learning environments and approa…
Preparing teacher-students for twenty-first-century learning practices (PREP 21) : a framework for enhancing collaborative problem-solving and strate…
2016
With regard to the growing interest in developing teacher education to match the twenty-first-century skills, while many assumptions have been made, there has been less theoretical elaboration and empirical research on this topic. The aim of this article is to present our pedagogical framework for the twenty-first-century learning practices in teacher education. We will first review the current status of policy frameworks for the twenty-first-century learning skills. Based on our previous work and current understanding in the field of learning sciences, we will next elaborate the processes and strategies for collaborative problem-solving skills and strategic learning skills to specify curre…
Cardiac threat appraisal and depression after first myocardial infarction
2012
The present study investigated cardiac threat appraisal and its association with depression after first myocardial infarction (MI). A semi-structured interview allowing for DSM-IV-Axis I diagnoses was administered to 36 patients after first MI. Patients completed self-reports 5 to 15 days after the MI (time 1), 6 to 8 weeks later (time 2) and again 6 months later (time 3). Assessments at time 1 included indices of cardiac threat appraisal, locus of control, coping, and depression while at time 2 and time 3 only measures of depression were obtained. Cardiac threat appraisal was significantly correlated with depression at time 1, but was unrelated to depression scores at time 2 and time 3. Fu…
Density functional theory description of random Cu-Au alloys
2019
Density functional alloy theory is used to accurately describe the three core effects controlling the thermodynamics of random Cu-Au alloys. These three core effects are exchange correlation (XC), local lattice relaxations (LLRs), and short-range order (SRO). Within the real-space grid-based projector augmented-wave (GPAW) method based on density functional theory (DFT), we adopt the quasinonuniform XC approximation (QNA), and take into account the LLR and the SRO effects. Our approach allows us to study the importance of all three core effects in a unified way within one DFT code. The results demonstrate the importance of the LLR term and show that going from the classical gradient level a…
Chloroquine for COVID-19: rationale, facts, hopes
2020
The tragedy of the pandemic coronavirus disease 2019 (COVID-19) led to a desperate search for effective treatments. Chloroquine (CQ), an aminoquinoline used for many years for the prophylaxis and therapy of malaria and autoimmune diseases, has been put forward as a treatment option. The fact that CQ is not patented and has been in clinical use for years is a major advantage. CQ has been shown to have antiviral effects in SARS, MERS, Ebola, and HIV infections, but without data showing clinical effectiveness [1, 2]. Does the current level of evidence suffice for prescribing CQ for COVID-19?
Improving Nearest Neighbor Based Multi-target Prediction Through Metric Learning
2017
The purpose of this work is to learn specific distance functions to be applied for multi-target regression problems using nearest neighbors. The idea of preserving the order relation between input and output vectors considering their corresponding distances is used along a maximal margin criterion to formulate a specific metric learning problem. Extensive experiments and the corresponding discussion try to put forward the advantages of the proposed algorithm that can be considered as a generalization of previously proposed approaches. Preliminary results suggest that this line of work can lead to very competitive algorithms with convenient properties.
