Data for: New approach for processing recycled carbon staple fiber yarns to unidirectional reinforced recycled carbon staple fiber tape
<p>This data set was generated at Leibniz-Institut für Verbundwerkstoffe GmbH in the project "Process analysis of the pseudo-plastic deformation behavior of unidirectional reinforced staple fiber organo sheets" is funded by the German Research Foundation (DFG) – funding reference 471480678. The goal was to develop a novel process approach for the further processing of staple fiber yarns made from long recycled carbon fibers (rCF) and polyamide 6 (PA6) to highly aligned staple fiber tapes. For this purpose, the input material as well as the manufactured tapes were characterized and examined in thermal analyses. In addition, the influence of the process parameters in the tape manufacturing process on the width and thickness of the tapes and the mechanical properties were investigated. The flexural and tensile properties were then compared with a laminate wound from the staple fiber yarns. The data set is divided in the results of the TGA, DSC, laser profile scans, tensile tests and flexural tests.</p>
Unidirectional transmembrane photoelectron transfer with artificial metallopeptides
<p>Unidirectional transmembrane electron transfer is an essential process in natural photosynthesis, where it plays a key role in separating reaction products and slowing charge recombination.<sup>1</sup> Making artificial molecules that functionally mimic photosynthetic proteins and achieve transmembrane electron transfer is already a chemical endeavour.<sup>2–7</sup> Distinguishing genuine transmembrane electron transfer through an impermeable lipid membrane, from light-induced leakage of electron donors through the membrane followed by photoelectron transfer on one side of the bilayer, is even more difficult.<sup>8–10</sup>Here, we report two artificial metallopeptides, <strong>WALP23-Ru<sub>2</sub></strong> and <strong>WALP23-Re<sub>2</sub></strong>, that drive photoelectron transfer from an electron donor located inside a liposome, to an acceptor located outside. A sensitive membrane leakage assay was used to demonstrate that <strong>WALP23-Re<sub>2</sub></strong> indeed achieved genuine photoelectron transfer through the membrane, with negligible contribution from leakage. By contrast, photoelectron transfer with <strong>WALP23-Ru<sub>2</sub></strong> was clearly the result of leakage of the electron donor through the membrane, followed by photoinduced electron transfer on one side of the membrane. These results demonstrate the unique potential of neutral metallopeptides such as <strong>WALP23-Re<sub>2</sub></strong> to drive transmembrane electron transfer in artificial photosynthetic systems, while highlighting the importance of leakage studies for the understanding of how such systems really work.</p>

Python code generating the data of figures 2, 3, 4, 5 and 6 of the manuscript: The evolution of cooperation in the unidirectional linear division of labour of finite roles
<p>The evolution of cooperation is an unsolved mystery, which we see in many social and biological systems. In the study titled "The evolution of cooperation in the unidirectional linear division of labour of finite roles", we investigate under which sanction systems and how the evolution of cooperation happens in the linear division of labour. </p> <p>This python code has been used to produce the results of Figures 2, 3, 4, 5, and 6 of the manuscript. This code shows the evolution of cooperation among the population of various different groups which have different roles to play in the linear division of labour, on the basis of numerical analysis of a partial differential equation system, which originates from the replicator equations used in the evolutionary game theory. We find the locally stable equilibria using this code, which shows the ultimate results of the dynamics in the system under given parameters. Figures 3, 5, and 6 are direct products of the code, showing the dynamics of a system, and figures 2 and 4 are the end results of those dynamics. </p> <p>We found that in a social dilemma situation, cooperation never evolves in the system without punishment. However, with sanction systems by introducing a suitable amount of punishment, while having a suitable findability of the defector, and a suitable initial population structure, cooperation can evolve. These results can be found with this code. We have no legal or ethical concerns regarding this data as this is a numerical analysis based on theoretical equations. </p>

Data from: Sperm quality, aggressiveness and generation turnover can facilitate unidirectional Y chromosome introgression across the European house mouse hybrid zone
The widespread and locally massive introgression of Y chromosomes of the eastern house mouse (<i>Mus musculus musculus</i>) into the range of the western subspecies (<i>M. m. domesticus</i>) in Central Europe calls for an explanation of its underlying mechanisms. Given the paternal inheritance pattern, obvious candidates for traits mediating the introgression are characters associated with sperm quantity and quality. We can also expect traits such as size, aggression, or the length of generation cycles to facilitate the spread. We have created two consomic strains carrying the non-recombining region of the Y chromosome of the opposite subspecies, allowing us to study introgression in both directions, something impossible in nature due to the unidirectionality of introgression. We analysed several traits potentially related to male fitness. Transmission of the <i>domesticus</i> Y onto the <i>musculus</i> background had negative effects on all studied traits. Likewise , <i>domesticus</i> males possessing the <i>musculus</i> Y had, on average, smaller body and testes and lower sperm count than the parental strain. However, the same consomic males tended to produce less dissociated sperm heads, to win more dyadic encounters, and to have shorter generation cycles than pure <i>domesticus</i> males. These data suggest the <i>domesticus</i> Y is disadvantageous on the <i>musculus</i> background while introgression in the opposite direction can confer a recognizable, though not always significant, selective advantage. Our results are thus congruent with the unidirectional <i>musculus</i>→domesticus Y chromosome introgression in Central Europe. In addition to some previous studies, they show this to be a multifaceted phenomenon demanding a multidisciplinary approach.
Data from: Unidirectional diploid–tetraploid introgression among British birch trees with shifting ranges shown by restriction site-associated markers
Hybridization may lead to introgression of genes among species. Introgression may be bidirectional or unidirectional, depending on factors such as the demography of the hybridizing species, or the nature of reproductive barriers between them. Previous microsatellite studies suggested bidirectional introgression between diploid Betula nana (dwarf birch) and tetraploid B. pubescens (downy birch) and also between B. pubescens and diploid B. pendula (silver birch) in Britain. Here, we analyse introgression among these species using 51 237 variants in restriction site-associated (RAD) markers in 194 individuals, called with allele dosages in the tetraploids. In contrast to the microsatellite study, we found unidirectional introgression into B. pubescens from both of the diploid species. This pattern fits better with the expected nature of the reproductive barrier between diploids and tetraploids. As in the microsatellite study, introgression into B. pubescens showed clear clines with increasing introgression from B. nana in the north and from B. pendula in the south. Unlike B. pendula alleles, introgression of B. nana alleles was found far from the current area of sympatry or allopatry between B. nana and B. pubescens. This pattern fits a shifting zone of hybridization due to Holocene reduction in the range of B. nana and expansion in the range of B. pubescens.
Data from: Examining the role of parasites in limiting unidirectional gene flow between lake and river sticklebacks
1. Parasites are important selective agents with the potential to limit gene flow between host populations by shaping local host immunocompetence. 2. We report on a contact zone between lake and river three-spined sticklebacks (Gasterosteus aculeatus) that offers the ideal biogeographic setting to explore the role of parasite-mediated selection on reproductive isolation. A waterfall acts as a natural barrier and enforces unidirectional migration from the upstream river stickleback population to the downstream river and lake populations. 3. We assessed population genetic structure and parasite communities over four years. In a set of controlled experimental infections, we compared parasite susceptibility of upstream and downstream fish by exposing laboratory-bred upstream river and lake fish, as well as hybrids, to two common lake parasite species: a generalist trematode parasite, Diplostomum pseudospathaceum and a host-specific cestode, Schistocephalus solidus. 4. We found consistent genetic differentiation between upstream and downstream populations across four sampling years, even though the downstream river consisted of ~10% first-generation migrants from the upstream population as detected by parentage analysis. Fish in the upstream population had lower genetic diversity and were strikingly devoid of macroparasites. Through experimental infections, we demonstrated that upstream fish and their hybrids had higher susceptibility to parasite infections than downstream fish. Despite this, naturally-sampled upstream migrants were less infected than downstream residents. Thus, migrants coming from a parasite-free environment may enjoy an initial fitness advantage, but their descendants seem likely to suffer from higher parasite loads. 5. Our results suggest that adaptation to distinct parasite communities can influence stickleback invasion success and may represent a barrier to gene flow, even between close and connected populations.
