A bstract A search for the $$ {B}_{\mathrm{s}}^0 $$ B s 0 → D *± D ∓ decay is performed using proton-proton collision data at centre-of-mass energies of 7, 8 and 13 TeV collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb − 1 . The decay is observed with a high significance and its branching fraction relative to the B 0 → D *± D ∓ decay is measured to be $$ \frac{\mathrm{\mathcal{B}}\left({B}_s^0\to {D}^{\ast \pm }{D}^{\mp}\right)}{\left({B}^0\to {D}^{\ast \pm }{D}^{\mp}\right)}=0.137\pm 0.017\pm 0.002\pm 0.006, $$ ℬ B s 0 → D ∗ ± D ∓ B 0 → D ∗ ± D ∓ = 0.137 ± 0.017 ± 0.002 ± 0.006 , where the first uncertainty is statistical, the second systematic and the third is due to the uncertainty on the ratio of the $$ {B}_{\mathrm{s}}^0 $$ B s 0 and B 0 hadronisation fractions.

Open Source Software (OSS) Foundations and projects are investing in creating Diversity and Inclusion (D&I) initiatives. However, little is known about contributors’ perceptions about the usefulness and success of such initiatives. We aim to close this gap by investigating how contributors perceive the state of D&I in their community. In collaboration with the Apache Software Foundation (ASF), we surveyed 600+ OSS contributors and conducted 11 follow-up interviews. We used mixed methods to analyze our data–quantitative analysis of Likert-scale questions and qualitative analysis of open-ended survey question and the interviews to understand contributors’ perceptions and critiques of the D&I initiative and how to improve it. Our results indicate that the ASF contributors felt that the state of D&I was still lacking, especially regarding gender, seniority, and English proficiency. Regarding the D&I initiative, some participants felt that the effort was unnecessary, while others agreed with the effort but critiqued its implementation. These findings show that D&I initiatives in OSS communities are a good start, but there is room for improvements. Our results can inspire the creation of new and the refinement of current initiatives.more » « less

These findings show that D&I initiatives in OSS communities are a good start, but there is room for improvements. Our results can inspire the creation of new and the refinement of current initiatives. Open Source Software (OSS) is widely used in society (e.g., Linux, Chrome, and Firefox), and contributing to these projects helps individuals learn and showcase their skills, so much so that the history of contributions are increasingly being analyzed by hirers. However, the people who contribute to OSS are predominately men (about 90%). This means that women and other minorities lose out on job opportunities and OSS projects lose out on diversity of thought. OSS organizations such as the Apache Software Foundation (ASF) promote a variety of initiatives to increase diversity and inclusion (D&I) in their projects, but they are piecemeal and little is known about contributors‘ perceptions about the usefulness and success of these initiatives. Here, we surveyed and interviewed ASF contributors to understand their perceptions about the state of D&I in the ASF and the effectiveness of existing D&I initiatives. Our findings show that individuals who are in the minority face challenges (e.g., stereotyping, lack of peer-network, and representation in decision making) and contributors‘ perceptions of the D&I initiative are a mixed bag, ranging from commending the current efforts to considering them to be “lip service”. These findings suggest that current D&I initiatives in OSS communities are a good start, but much needs be done in terms of creating new successful initiatives and refining current ones.more » « less

The Drosophila kikkawai feature with Gene ID 108083276 was determined to be an ortholog of Drosophila melanogaster absent, small, or homeotic discs 1 (ash1). Two isoforms, ash1-PB and ash1-PC, were constructed on the D. kikkawai Muller D element using the GEP annotation protocol. The second coding exon of D. kikkawai ash1 includes an insertion translated into 18 additional amino acids compared to the D. melanogaster protein and is supported by RNA-Seq coverage, the lack of splice junction predictions, and multiple gene predictors. The first intron in both isoforms of D. kikkawai ash1 contains a well conserved non-canonical GC splice site.more » « less
