Seizure Prediction Using EEG Channel Selection Method

2022

Seizure prediction using intracranial electroencephalogram (iEEG) is still challenging because of complicated signals in spatial and time domains. Feature selection in the spatial domain (i.e., channel selection) has been largely ignored in this field. Hence, in this paper, a novel approach of iEEG channel selection strategy combined with one-dimensional convolutional neural networks (1D-CNN) was presented for seizure prediction. First, 15-sec and 30-sec iEEG segments with an increasing number of channels (from one channel to all channels) were sequentially fed into 1D-CNN models for training and testing. Then, the channel case with the best classification rate was selected for each partici…

Debunking the myth of high achievers in Finnish primary teacher education: first-year preservice teachers’ learning strategies and study success

2022

This study aimed to explore the admitted students of Finnish primary teacher education programmes from the viewpoint of learning strategies, and academic success. An overall view was derived from national register data, which were supplemented with questionnaire data gathered from three teacher education units (N = 216). Primary teacher programmes currently seem to attract and select mediocre secondary school graduates from academic perspective, contrary to previous studies. Furthermore, women enter the programmes with higher exam scores than men and have more success in their studies. Based on their learning strategies, students were divided into subgroups of deep and independent learners,…

Ecology, fisheries and management of wild brown trout populations in boreal inland waters

2010

Eutrophication of aquatic ecosystems is an increasing problem, especially threatening small and shallow freshwater lakes. While the extreme inputs of nutrients (phosphorus and nitrogen) can nowadays be reduced and controlled rather efficiently, additional measures to reverse eutrophication may be needed. These often involve biomanipulation, typically mass removal of cyprinid fish. However, the success of biomanipulations has many times been limited or short lived. The reasons for this are not well known, perhaps because the more subtle impacts of biomanipulation on the ecosystem-wide processes of lakes have not been thoroughly studied. Natural abundance stable isotopes may provide a cost-ef…

Evidence for Positive Selection in the Capsid Protein-Coding Region of the Foot-and-Mouth Disease Virus (FMDV) Subjected to Experimental Passage Regi…

2001

We present sequence data from two genomic regions of foot-and-mouth disease virus (FMDV) subjected to several experimental passage regimens. Maximum-likelihood estimates of the nonsynonymous-to-synonymous rate ratio parameter (dN/dS) suggested the action of positive selection on some antigenic sites of the FMDV capsid during some experimental passages. These antigenic sites showed an accumulation of convergent amino acid replacements during massive serial cytolytic passages and also in persistent infections of FMDV in cell culture. This accumulation was most significant at the antigenic site A (the G-H loop of capsid VP1), which includes an Arg-Gly-Asp (RGD) cellular recognition motif. Our …

Crafting the Commons: The Art of Selecting Conservative and Labour Parliamentary Candidates for the 2015 General Election

2015

International audience; Crafting the Commons: The Art of Selecting Conservative and Labour Parliamentary Candidates for the 2015 General ElectionThe selection of parliamentary candidates for the general election is one of the most crucial tasks carried out by local parties who have long enjoyed relative autonomy from party headquarters in this respect. But because the aggregate choices of individual local parties determine the composition of the parliamentary parties, the party leaderships in both parties have devised new strategies and rules allowing them to influence that choice. This is in order both to ensure both that future MPs are more in tune with the leadership line and that the so…

A NETWORK PERSPECTIVE ON CO-BRANDING CAMPAIGNS: EVIDENCE FROM THE FASHION INDUSTRY

Co-branding strategies have attracted increasing attention in the academic community over the last decades. Previous research privileged the analysis of co-branding campaigns by studying dyadic relationships between brands. Here, we take a network view to highlight the influence of the single companies' co-branding portfolio on partnership formation. From a theoretical perspective, the studies on co-branding analyze the process through which partner brands send a "signal" to consumers. Here, instead, we propose to look at partner selection as a process in which a signal, namely, the portfolio of previous co-branding campaigns, is sent from one brand to the others. In particular, we focus on…

Diverse partner selection with brood recombination in genetic programming

2018

The ultimate goal of learning algorithms is to find the best solution from a search space without testing each and every solution available in the search space. During the evolution process new solutions (children) are produced from existing solutions (parents), where new solutions are expected to be better than existing solutions. This paper presents a new parent selection method for the crossover operation in genetic programming. The idea is to promote crossover between two behaviourally (phenotype) diverse parents such that the probability of children being better than their parents increases. The relative phenotype strengths and weaknesses of pairs of parents are exploited to find out i…

Peer selection and influence : Students’ interest-driven socio-digital participation and friendship networks

2020

Digital technologies have been increasingly embedded in students’ everyday lives. Interest-driven socio-digital participation (ISDP) involves students’ pursuit of interests mediated by computers, social media, the internet, and mobile devices’ integrated systems.ISDPis likely to intertwine closely with young people’s social networks that has been scarcely studied quantitatively. To close this gap, the present paper investigated students’ peer selection and influence effects of the intensity of their ISDP and friendship networks. We collected two-wave data by administering a peer nomination to trace students’ friendship networks with peers and a self-reported questionnaire to examine student…
