Dataset used in Paper 1046 of the IFAC World Congress 2020 "Data Quality Assessment for System Identification in the Age of Big Data and Industry 4.0"
<p><br> The data used was obtained from a section of the lead zinc concentrator at the Mount Isa Mines in Queensland, Australia.The data collected for this investigation consists of two months of plant operation, collected at a a frequency of one minute. The historian’s interpolation routine is used to ensure the data is aligned. No special care was used to ensure that the data had any particular characteristics, other than that the plant was running. It was reported that during this period some step tests had been conducted. Forty-three variables were collected: for each of the PID controllers, setpoint, process value and output (SV/PV/MV) were recorded. The three analysers provide measure of iron, lead and zinc percentages.</p>
Data from: Long‐term follow‐up, quality of life and survival of Lambert‐Eaton myasthenic syndrome patients
Objective To study survival and characterize long-term functional impairments as well as health-related quality of life (HRQOL) of Lambert-Eaton myasthenic syndrome (LEMS) patients. Methods In this observational study, survival of LEMS patients, separately for non-tumor (NT) and small-cell lung cancer (SCLC), was compared to the Dutch general population and to patients with SCLC. Disease course in LEMS patients was recorded retrospectively. Several scales for functional impairments and health-related quality of life were assessed. Results We included 150 LEMS patients. Survival was similar to the general population in 65 NT-LEMS patients. Tumor survival was significantly longer in 81 SCLC-LEMS patients compared to non-LEMS SCLC patients (overall median survival 17 vs. 7.0 months, p<0.0001). At diagnosis, 39 patients (62%) of 63 patients with complete follow-up data were independent for ADL activities, improving to 85% at 1-year follow-up. Physical HRQOL composite score (55.9) was significantly lower than in the general population (76.3, p<0.0001) and comparable to myasthenia gravis (60.5) Mental HRQOL composite score was 71.8 in LEMS patients, comparable to the general population (77.9, p=0.19) and myasthenia gravis (70.3). Conclusions This study shows NT-LEMS patients have normal survival. SCLC-LEMS patients have an improved tumor survival, even after correcting for tumor stage. A majority of LEMS patients report a stable disease course and remain or become independent for self-care after treatment.
Data for: Benchmarking Oxford Nanopore read assemblers for high-quality molluscan genomes
<p><span>Choosing the optimum assembly approach is essential to achieving a high-quality genome assembly suitable for comparative and evolutionary genomic investigations. Significant recent progress in long-read sequencing technologies such as PacBio and Oxford Nanopore Technologies (ONT) also brought about a large variety of assemblers. Although these have been extensively tested on model species such as <i>Homo sapiens </i>and <i>Drosophila melanogaster</i>, such benchmarking has not been done in Mollusca which lacks widely adopted model species. Molluscan genomes are notoriously rich in repeats and are often highly heterozygous, making their assembly challenging. Here, we benchmarked 10 assemblers based on ONT raw reads from two published molluscan genomes of differing properties, the gastropod <i>Chrysomallon squamiferum </i>(356.6Mb, 1.59% heterozygosity) and the bivalve <i>Mytilus coruscus</i> (1593Mb, 1.94% heterozygosity). By optimising the assembly pipeline, we greatly improved both genomes from previously published versions. Our results suggested that 40-50X of ONT reads are sufficient for high-quality genomes, with Flye being the recommended assembler for compact and less heterozygous genomes exemplified by <i>C. squamiferum</i>, while NextDenovo excelled for more repetitive and heterozygous molluscan genomes exemplified by <i>M. coruscus</i>. A phylogenomic analysis utilising the two updated genomes with other 32 published high-quality lophotrochozoan genomes resulted in maximum support across all nodes, and we show that improved genome quality also leads to more complete matrices for phylogenomic inferences. Our benchmarking will ensure the efficiency in future assemblies for molluscs and perhaps also other marine phyla with few genomes available.</span></p>
Data from: Telomere length reflects phenotypic quality and costs of reproduction in a long-lived seabird
Telomere length is associated with cellular senescence, lifestyle and ageing. Short telomeres indicate poor health in humans and reduced life expectancy in several bird species, but little is known about telomeres in relation to phenotypic quality in wild animals. We investigated telomere lengths in erythrocytes of known-age common terns (Sterna hirundo), a migratory seabird, in relation to arrival date and reproductive performance. Cross-sectional data revealed that, independent of age, individuals with short telomeres performed better: they arrived and reproduced earlier in the season and had more chicks in the nest. The latter effect was stronger the older the brood and stronger in males, which do most of the chick provisioning. Longitudinal data confirmed this pattern: compared with birds that lost their brood, birds that raised chicks beyond the 10th nestling day experienced higher telomere attrition from one year to the next. However, more detailed analysis revealed that the least and most successful individuals lost the fewest base pairs compared with birds with intermediate success. Our results suggest that reproductive success is achieved at the expense of telomeres, but that individual heterogeneity in susceptibility to such detrimental effects is important, as indicated by low telomere loss in the most successful birds.
Data from: Body height and immune efficacy: testing body stature as a signal of biological quality
According to the good genes hypothesis and energy allocation theory, human adult body height may reflect biological quality. An important aspect of this quality is immune system functioning (ISF). The aim of this study was to evaluate the relationship between ISF and body height in healthy people. The ISF was determined by several important innate (total complement and lysozyme activity, neutrophils function) and adaptive immune parameters (lymphocytes, IgA and IgG, and response to flu vaccine). Overall, 96 males and 97 females were subjected to flu vaccination, and of these 35 males and 34 females were subjected to tetanus. Blood samples were collected before and 4 weeks after vaccination. Immunomodulatory factors: participant's age, body fat and free testosterone levels, were controlled. There was no association between body height and all analysed immune parameters for both sexes. That might suggest that in western society, a women's preference for taller men is not related to "good genes for immune competence". We propose the novel Immunity Priority Hypothesis that explains the lack of relationship between adult body stature and ISF. This hypothesis, however, does not contradict the signalling role of a man's body height as a morphological marker of biological quality.
