Open-Ended Coaxial Cable Measurements in Diesel-Contaminated soil during Bioremediation
<p>Complex dielectric permittivity was measured over a broad frequency range (200 MHz to 20 GHz) with Keysight 85070D dielectric probe kit connected to a network analyzer (Keysight N5227A), on a series of 6 soil microcosms contaminated with diesel oil, before and after a process of bioremediation. This technology measures separately the real and the imaginary component of complex dielectric permittivity, which are meaningful properties of soil.</p>

Data from: The maintenance and emergence of diversity promotes open-ended evolution in a prebiotic context
<p>This data was collected during the study entitled “The maintenance and emergence of diversity promotes open-ended evolution in a prebiotic context."<br> <br>We explored how selective contexts shape the evolution of innovation, using <em>in vitro </em>selection with single-stranded DNA (ssDNA) as an empirical model for pre-cellular evolution. During this selection regime, a diverse pool of 76-bp ssDNA (consisting of a random 40-nt region, flanked by 18-nt primer binding sites) was incubated with a target substrate, during which sequences were able to bind to the substrate. Following incubation, unbound sequences were discarded, while bound sequences were partitioned and amplified via PCR and used in subsequent rounds of selection. <br> <br>Our experimental design consisted of 8 cycles of selection with either streptavidin-coated magnetic beads or yeast cells (<em>Kluyveromyces lactis</em>) as the binding substrate. We also included two variable selection regimes, where four rounds of selection were completed with one substrate before switching to the other target for the remaining four rounds (3 replicate populations per treatment). All replicates from rounds 1, 4, 7, and 8 were purified and submitted for next-generation sequencing (Illumina NovaSeq S4 2x150-bp lane), along with the random starting library. Sequencing generated a mean of 29,741,261 pair-end reads per sample, which were assembled and normalized to ~100,000 reads per sample used for analysis, which are included here.<br> <br>The file names are organized in the following format: Selection Treatment_Round of Selection_Replicate #. For example, “Beads_R1_1” indicates a population that was selected with beads as the binding substrate following Round 1 of selection, replicate population 1 (out of 3 replicates). Scripts used to list contigs (<em>EditFastas.l</em>) and measure the frequencies of each sequence (<em>CountSeqs.l</em> ) are also included.</p>
E2EGit: A Dataset of End-to-End Web Tests in Open Source Projects
<p><strong>ABSTRACT </strong><br>End-to-end (E2E) testing is a software validation approach that simulates realistic user scenarios throughout the entire workflow of an application. In the context of web<br>applications, E2E testing involves two activities: Graphic User Interface (GUI) testing, which simulates user interactions with the web app’s GUI through web browsers, and performance testing, which evaluates system workload handling. Despite its recognized importance in delivering high-quality web applications, the availability of large-scale datasets featuring real-world E2E web tests remains limited, hindering research in the field.<br>To address this gap, we present E2EGit, a comprehensive dataset of non-trivial open-source web projects collected on GitHub that adopt E2E testing. By analyzing over 5,000 web repositories across popular programming languages (JAVA, JAVASCRIPT, TYPESCRIPT, and PYTHON), we identified 472 repositories implementing 43,670 automated Web GUI tests with popular browser automation frameworks (SELENIUM, PLAYWRIGHT, CYPRESS, PUPPETEER), and 84 repositories that featured 271 automated performance tests implemented leveraging the most popular open-source tools (JMETER, LOCUST). Among these, 13 repositories implemented both types of testing for a total of 786 Web GUI tests and 61 performance tests.</p> <p><br><strong>DATASET DESCRIPTION </strong><br>The dataset is provided as an SQLite database, whose structure is illustrated in Figure 3 (in the paper), which consists of five tables, each serving a specific purpose.<br>The <em>repository </em>table contains information on 1.5 million repositories collected using the SEART tool on May 4. It includes 34 fields detailing repository characteristics. The<br><em>non_trivial_repository</em> table is a subset of the previous one, listing repositories that passed the two filtering stages described in the pipeline. For each repository, it specifies whether it is a web repository using JAVA, JAVASCRIPT, TYPESCRIPT, or PYTHON frameworks. A repository may use multiple frameworks, with corresponding fields (e.g., is web java) set to true, and the field web dependencies listing the detected web frameworks. For Web GUI testing, the dataset includes two additional tables; <em>gui_testing_test _details</em>, where each row represents a test file, providing the file path, the browser automation framework used, the test engine employed, and the number of tests implemented in the file. <em>gui_testing_repo_details</em>, aggregating data from the previous table at the repository level. Each of the 472 repositories has a row summarizing<br>the number of test files using frameworks like SELENIUM or PLAYWRIGHT, test engines like JUNIT, and the total number of tests identified. For performance testing, the <em>performance_testing_test_details</em> table contains 410 rows, one for each test identified. Each row includes the file path, whether the test uses JMETER or LOCUST, and extracted details such as the number of thread groups, concurrent users, and requests. Notably, some fields may be absent—for instance, if external files (e.g., CSVs defining workloads) were unavailable, or in the case of Locust tests, where parameters like duration and concurrent users are specified via the command line.</p> <p><strong>To cite this article refer to this citation:</strong></p> <p>@inproceedings{di2025e2egit,<br> title={E2EGit: A Dataset of End-to-End Web Tests in Open Source Projects},<br> author={Di Meglio, Sergio and Starace, Luigi Libero Lucio and Pontillo, Valeria and Opdebeeck, Ruben and De Roover, Coen and Di Martino, Sergio},<br> booktitle={2025 IEEE/ACM 22nd International Conference on Mining Software Repositories (MSR)},<br> pages={10--15},<br> year={2025},<br> organization={IEEE/ACM}<br>}<br><br>This work has been partially supported by the Italian PNRR MUR project PE0000013-FAIR. </p>
Neural FoxP2 expression in an aging open-ended vocal learner
<p>Most vocal learning species exhibit an early critical period during which their vocal control neural circuity can facilitate the acquisition of new vocalizations. Some taxa, most notably humans and parrots, retain this neurobehavioral plasticity throughout adulthood. Downregulation of the transcription factor FoxP2 in both songbird and parrot vocal control nuclei has been identified as a key expression pattern facilitating vocal learning. We hypothesize that open-ended vocal learning is vulnerable to cognitive decline, and that this deterioration will be reflected in age-related changes in neural FoxP2 expression. We tested this hypothesis in the budgerigar (<em>Melopsittacus undulatus</em>), a small gregarious parrot in which adults converge on shared call types in response to shifts in group membership. We formed novel flocks of 4 previously unfamiliar males belonging to the same age class, either "young adult" (6 mo-1 yr) or "older adult" (≥ 3 yr), and then collected audio-recordings over a 20-day learning period to assess vocal learning ability. Following behavioral recording, whole brains were extracted and immunohistochemistry was performed to measure FoxP2 protein expression in a parrot vocal learning center, the magnocellular nucleus of the medial striatum (MMSt), and its adjacent striatum. We find similarly downregulated FoxP2 expression and equivalent vocal plasticity and vocal convergence in young and older adults suggesting the maintenance of two components of open-ended learning into old age in the budgerigar. No relationship between individual variation in vocal learning measures and FoxP2 expression was detected.</p>
