Extended Data for: Quality-Diversity Search in Sound Generation: Investigating Innovation Engines for Audio Exploration
Data accompanying the article Quality-Diversity Search in Sound Generation: Investigating Innovation Engines for Audio Exploration. The Innovation Engine algorithm is used to evolve sounds, where Quality Diversity search is guided by the YAMNet classifier to discover sounds.This study draws on the challenges that composers and sound designers face in
creating and refining new tools to achieve their musical goals. Utilising evolution-
ary processes to promote diversity and foster serendipitous discoveries, we propose
to automate the search through uncharted sonic spaces for sound discovery. We
argue that such diversity promoting algorithms can bridge a technological gap
between the theoretical realisation and practical accessibility of sounds. Specif-
ically, in this paper we describe a system for generative sound synthesis using
a combination of Quality Diversity (QD) algorithms and a supervised discrimi-
native model, inspired by the Innovation Engine algorithm. The study explores
different configurations of the generative system and investigates the interplay
between the chosen sound synthesis approach and the discriminative model. We
further examine the interaction between Compositional Pattern Producing Net-
works (CPPNs) and Digital Signal Processing (DSP) graphs, introducing a novel
approach with multiple specialized CPPNs for different frequency ranges. This
configuration results in simpler CPPN networks while maintaining comparable
performance to single-CPPN setups. The research also investigates evolution-
ary stepping stones by analyzing goal switches between musical and non-musical
contexts, revealing how lineages traverse unlikely paths to current elites. Addi-
tionally, we explore the temporal dimension of sound generation by expanding
the behavior space from a previous study to include various sound durations,
uncovering specialization within temporal niches. The results indicate that a
combination of CPPN + Digital Signal Processing (DSP) graphs coupled with
Multi-dimensional Archive of Phenotypic Elites (MAP-Elites) and a deep learn-
ing classifier can generate a substantial variety of synthetic sounds. Our expanded
experiments demonstrate the system’s ability to produce diverse and innovative
sound objects across different temporal and contextual dimensions. The study
concludes by presenting the generated sound objects through an online explorer
and as rendered sound files. Furthermore, in the context of music composition,
we present an experimental application that showcases the creative potential of
our discovered sounds, highlighting the system’s capacity for generating versatile
sonic material across various durations and contexts
Background Data for: Evaluation of ambulance blood cultures in patients with suspected sepsis. A rural prospective cohort study
This dataset is extracted from an ambulance quality registry of patients with suspected sepsis managed by the ambulance department of the University Hospital of North Norway. The dataset contains data from patients with suspected sepsis who were subject to blood culture sampling before or after transport to hospital by ambulance from May 2018 to August 2022. The dataset was extracted to conduct a study on the value of blood cultures from patients with suspected sepsis drawn by ambulance personnel. The dataset contains demographic data and clinical data from both prehospital and in-hospital setting. The Regional Committee for Medical and Health Research Ethics Northern Norway (application number 685406) approved the present study.Related article abstract
Purpose: To describe the epidemiology of blood cultures (BCs) drawn from patients with suspected sepsis by a rural ambulance service.
Methods: Patients were included if they had clinically suspected sepsis and at least one BC was drawn. Variables associated with positive BCs were identified with logistic regression, culture results before and after ambulance antimicrobial therapy were compared and the susceptibility to empirical antimicrobial therapy in bacterial isolates was determined.
Results: Among 392 included patients, sepsis severity scores were higher when BCs were positive than negative, but there was no significant difference in 30-day all-cause mortality between BC negative and positive patients. In 47 patients ambulance blood cultures were positive (47/347 (13,5%)). Fever (OR 1.54, 95% CI 1.11-2.15) and age (OR 1.01, 95% CI 1.00-1.04) was associated with higher odds of positive cultures, whereas lower respiratory tract infection was associated with lower odds of positive cultures (OR 0.10, 95% CI 0.04-0.30). In 205 patients who had both ambulance and hospital BCs drawn and received ambulance antimicrobial therapy, only the ambulance BCs were positive in 16 patients, whereas in 4 patients only hospital cultures were positive. Bacterial isolates from positive BCs were susceptible to the empirical antimicrobial regimen in 80% of cases.
Conclusion: Positive ambulance BCs were associated with higher sepsis severity, and ambulance cultures were most useful in febrile patients with a suspected focus of infection other than the lower airways. Repeated BCs after hospital admission added only limited diagnostic value if an adequate ambulance BC had already been drawn.</p

Replication Data for: Decomposition of plant, fungal and tea litter in Picea abies forests with and without a history of clear-cutting
Litter decomposition is coupled to carbon (C) sequestration through C release to the atmosphere, C transformation and nutrient release to the soil. We investigated if clear-cutting has long-term effects on this vital ecological process and consequently on C dynamics in boreal forests using twelve pairs of previously clear-cut and near-natural forests.
This study is part of the EcoForest project: https://ecoforest.no/.
This dataset contains data on three decomposition experiments in 12 pairs of forests in South-Eastern Norway. The forests were paired across harvesting history to consist of one previously clear-cut forest and one near-natural forest i.e. never clear-cut.
The litter used in the three experiments were:
(I) plant leaf litter,
(II) fungal necromass,
(III) tea (Tea Bag Index)
Replication Data for: Parasite infection shapes the pathobiome and behavior of marine zooplankton
Data and scripts for replicating the results in the article `Garvang et al., 2025. Parasite infection shapes the pathobiome and behavior of marine zooplankton. Limnology and Oceanography Letters`.
We collected Calanus helgolandicus from the Oslofjord, both healthy individuals and infected with a conspicuous "yellow-hyphal" parasite that changes the host behavior. We incubated them for 7 days and measured behavior and survival. At the start and end of the incubation we sampled animals for 16S rRNA microbial community analysis. Infected Calanus had higher mortality, more risky behavior and altered microbiomes compared to the uninfected.
The repository contains a workflow description of how to process and analyze the raw 16S, survival, and behavior data, and all necessary scripts. The raw 16S sequence data is not available in this repository, but has been deposited to the European Nucleotide Archive with project accession PRJEB84185.Abstract from related publication:
When assessing the total impact of disease in a host, it is important to consider not only the disease-carrying agent but also all symbionts, as they affect and are affected by the course of disease. This concept of a pathobiome is increasingly recognized in disease ecology, but is not well-investigated in natural systems. Copepods are key organisms in marine ecosystems and host a variety of symbionts, including bacteria and eukaryotic parasites. We investigated the impact of a taxonomically uncertain yellow-hyphal parasite (YHP) on its copepod host Calanus helgolandicus with an incubation experiment, comparing survival, behavior, and microbiomes of uninfected and infected hosts. Infected hosts had higher mortality, and altered behavior which can increase predation risk. The microbiomes differed between infected and uninfected hosts, and we identified several potential contributing taxa to the Calanus-YHP pathobiome using model-based ordination.</p

Replication Data for: Romanian plăcea ‘like’: An Alternating Dat-Nom/Nom-Dat Verb
This data serves as the basis for the collaborative article titled "Romanian plăcea ‘like’: An Alternating Dat-Nom/Nom-Dat Verb", where the alternating status of the verb plăcea ‘like’ is being investigated. In this article, we take SVO to be the canonical word order in Romanian, while being aware of the complexity of the topic, too big to address here (Ilioaia 2023; Pană Dindelegan 2016; cf. also Nicolae 2019). Given this, we predict that, in the case of the verb plăcea ‘like’, both the dative-before-nominative and the nominative-before-dative orders are SVO structures in Romanian, instantiating the two argument structures, Dat-Nom and Nom-Dat, respectively, instead of one of the word orders being a topicalization of the other. To verify this hypothesis, we have carried out a synchronic corpus study, providing word order statistics for the verb plăcea ‘like’, and as a control, also for the verb mulțumi ‘thank’, which is an unambiguous Nom-Dat verb.
Thus, we have collected material for both verbs from the Romanian Web Corpus roTenTen16 (Jakubíček et al. 2013), which consists of 2.6 billion words. We have extracted a sample including the first 200 main clause tokens for each of the two verbs, where these occur with two arguments, a nominative and a dative, at a distance of zero-to-three words. We have only included tokens where the two arguments are represented as either full NPs or strong pronouns, with one of the arguments being preverbal and the other postverbal. Examples where either of the two arguments are pro-dropped are excluded for the simple reason that the arguments are not expressed in such examples, which in turn makes it difficult to exactly decide on their position in the clause.
In addition to the two data files, we include in this dataset codebooks for the respective data files, as well as files containing tables and graphs used in the related publication.Abstract article:
In several Indo-European languages, including Romanian, predicates such as plăcea ‘like' from Latin placēre ‘like, please’, are found selecting for a dative experiencer and a nominative stimulus, which appear to allow for two opposite, but equally neutral, word orders, i.e. dative-before-nominative and nominative-before-dative. This stands in stark contrast with topicalized datives, which are always focal in Romanian. We hypothesize that the two word orders with plăcea represent two diametrically-opposed argument structures, Dat-Nom and Nom-Dat, thus predicting that the dative behaves syntactically as a subject in Dat-Nom structures and the nominative as a subject in Nom-Dat structures. An inspection of seven subject tests, recently applied in the literature on Romanian, reveals that two of these do not distinguish between subjects and objects, while the remaining five confirm that either argument of plăcea, the dative or the nominative, passes the subject tests, with the other argument, the nominative or the dative, behaving as an object
Replication Data for: Long-term homogenization of Fennoscandian heathland and tundra vegetation is connected to the expansion of an allelopathic dwarf shrub
This dataset contain plant community data (including vascular plants, bryophytes and lichens) from 275 vegetation plots from northern Fennoscandia (northern Finland and northern Norway). Values for each species are percentage cover estimates from 2 x 2 meter plot. Each plot has been surveyed twice, i.e., species have old and new percentage cover from 1964-75 and from 2013-23.
We analyzed temporal changes in community composition and diversity across the study area and in different biogeographic zones, continentality-humidity classes and habitat types. We found a strong homogenization trend across the study area, with plant communities becoming more similar in composition over the decades when all taxa were treated together. The observed homogenization was driven especially by the increased similarity of vascular plant and lichen communities and was largely independent of biogeographic zones or continentality-humidity gradient. Homogenization was particularly associated with the drastic encroachment of the evergreen dwarf shrub Empetrum nigrum in habitat types originally dominated by other species, and with the decrease in lichen cover. In general, our findings suggest that Fennoscandian heathland and tundra vegetation is transforming towards a more homogeneous evergreen dwarf shrub-dominated system, which may threaten ecosystem multifunctionality. Our results highlight the importance of exploring biodiversity among different metrics and growth forms to understand the overall changes in heathland and tundra biodiversity
