Data underpinning "Transmon platform for quantum computing challenged by chaotic fluctuations"
<p>Data set underlying the figures in the article "Transmon platform for quantum computing challenged by chaotic fluctuations" (https://doi.org/10.1038/s41467-022-29940-y)</p><p>From the perspective of many-body physics, the transmon qubit architectures currently developed for quantum computing are systems of coupled nonlinear quantum resonators. A certain amount of intentional frequency detuning ('disorder') is crucially required to protect individual qubit states against the destabilizing effects of nonlinear resonator coupling. In our paper, we investigate the stability of this variant of a many-body localized phase for system parameters relevant to current quantum processors developed by the IBM, Delft, and Google consortia, considering the cases of natural or engineered disorder. Applying three independent diagnostics of localization theory — a Kullback–Leibler analysis of spectral statistics, statistics of many-body wave functions (inverse participation ratios), and a Walsh transform of the many-body spectrum — we find that some of these computing platforms are dangerously close to a phase of uncontrollable chaotic fluctuations.</p>
Evolution of the Sabulina verna group (Caryophyllaceae) in Europe: A deep split, followed by secondary contacts, multiple allopolyploidization and colonization of challenging substrates
<p>One of the major goals of contemporary evolutionary biology is to elucidate the relative roles of allopatric and ecological differentiation and polyploidy in speciation. In this study, we address the taxonomically intricate <em>Sabulina verna</em> group, which has a disjunct Arctic–alpine postglacial range in Europe and occupies a broad range of ecological niches, including substrates toxic to plants. Using genome-wide ddRAD sequencing combined with morphometric analyses based on extensive sampling of 111 natural populations, we aimed to disentangle internal evolutionary relationships and examine their correspondence with the pronounced edaphic and ploidy diversity within the group. We identified two spatially distinct groups of diploids: a widespread Arctic–alpine group and a spatially restricted yet diverse Balkan group. Most tetraploids exhibited a considerably admixed ancestry derived from both these groups, suggesting their allopolyploid origin. Four genetic clusters in congruence with geography and mostly supported by morphological traits were recognized in the diploid Arctic–alpine group. Tetraploids are split into two distinct and geographically vicariant groups, indicating their repeated polytopic origin. Furthermore, our results also revealed at least five-fold parallel colonization of toxic substrates (serpentine and metalliferous), altogether demonstrating a complex interaction between geography, challenging substrates, and polyploidy in the evolution of the group. Finally, we propose a new taxonomic treatment of this intricate complex.</p>
Supplementary Material for: On the Challenges to Documenting Requirements in Agile Software Development: A Practitioners' Perspective
<p><strong>Abstract: </strong>Agile Software Development (ASD) is an iterative and incremental methodology designed to accelerate project deliveries. In this dynamic environment characterized by constant changes, the task of documenting requirements becomes increasingly challenging, leading to the emergence of the technical debt issue. This research involved a survey of 84 practitioners to identify the techniques and practices employed in documenting software requirements within ASD teams, as well as their perceptions of the documentation process and the challenges, regarding what factors influence it and its consequences. Our key findings indicate that user stories are the most commonly utilized technique by practitioners for documenting requirements. Furthermore, a deficient documentation process results in two primary consequences: rework and a knowledge deficit. To address these challenges, various techniques are implemented across different development phases, including requirement refactoring, documentation refinement meetings, and template reviews. Participants also emphasized the significance of having a requirements expert to enhance the documentation process and expressed uncertainty regarding the adequacy of their existing requirements documentation. This study highlights the growing issue of technical debt within ASD teams' documentation and requirements and raises awareness about the need to develop habits for documenting and maintaining up-to-date software requirements in agile projects.</p>

<p>Background: It is not known how the number of deaths due to COVID-19 compare to the number of deaths due to "unsafe water, sanitation, and handwashing" during the COVID-19 global health emergency.</p> <p>Methods: A dataset of deaths due to COVID-19 was downloaded from the World Health Organization. A dataset summarizing deaths due to unsafe water, sanitation, and handwashing was obtained from the Institute for Health Metrics and Evaluation (IHME). </p> <p>Results indicate that COVID-19 deaths in Africa and South East Asia regions exceeded those due to unsafe water, sanitation, and hygiene. </p>
