Auditory streaming involves perceptually assigning overlapping sound sequences to their respective sources. Although critical for acoustic communication, few studies have investigated the role of auditory streaming in nonhuman animals. This study used the rhythmic masking release paradigm to investigate auditory streaming in Cope's gray treefrog (Hyla chrysoscelis). In this paradigm, the temporal rhythm of a Target sequence is masked in the presence of a Distractor sequence. A release from masking can be induced by adding a Captor sequence that perceptually “captures” the Distractor into an auditory stream segregated from the Target. Here, the Target was a sequence of repeated pulses mimicking the rhythm of the species' advertisement call. Gravid females exhibited robust phonotaxis to the Target alone, but responses declined significantly when Target pulses were interleaved with those of a Distractor at the same frequency, indicating the Target's attractive temporal rhythm was masked. However, addition of a remote-frequency Captor resulted in a significant increase in responses to the Target, suggesting the Target could be segregated from a separate stream consisting of integrated Distractor and Captor sequences. This result sheds light on how auditory streaming may facilitate acoustic communication in frogs and other animals.more » « lessFree, publicly-accessible full text available April 1, 2026

The increasing deployment of ML models on the critical path of production applications requires ML inference serving systems to serve these models under unpredictable and bursty request arrival rates. Serving many models under such conditions requires a careful balance between each application's latency and accuracy requirements and the overall efficiency of utilization of scarce resources. Faced with this tension, state-of-the-art systems either choose a single model representing a static point in the latency-accuracy tradeoff space to serve all requests or incur latency target violations by loading specific models on the critical path of request serving. Our work instead resolves this tension through a resource-efficient serving of the entire range of models spanning the latency-accuracy tradeoff space. Our novel mechanism, SubNetAct, achieves this by carefully inserting specialized control-flow operators in pre-trained, weight-shared super-networks. These operators enable SubNetAct to dynamically route a request through the network to actuate a specific model that meets the request's latency and accuracy target. Thus, SubNetAct can serve a vastly higher number of models than prior systems while requiring upto 2.6\texttimes{} lower memory. More crucially, SubNetAct's near-instantaneous actuation of a wide-range of models unlocks the design space of fine-grained, reactive scheduling policies. We design one such extremely effective policy, SlackFit, and instantiate both SubNetAct and Slack-Fit in a real system, SuperServe. On real-world traces derived from a Microsoft workload, SuperServe achieves 4.67\% higher accuracy for the same latency targets and 2.85\texttimes{} higher latency target attainment for the same accuracy.more » « lessFree, publicly-accessible full text available April 28, 2026

Data dashboards provide a means for sharing multiple data products at a glance and were ubiquitous during the COVID-19 pandemic. Data dashboards tracked global and country-specific statistics and provided cartographic visualizations of cases, deaths, vaccination rates and other metrics. We examined the role of geospatial data on COVID-19 dashboards in the form of maps, charts, and graphs. We organize our review of 193 COVID-19 dashboards by region and compare the accessibility and operationality of dashboards over time and the use of web maps and geospatial visualizations. We found that of the dashboards reviewed, only 17% included geospatial visualizations. We observe that many of the COVID-19 dashboards from our analysis are no longer accessible (66%) and consider the ephemeral nature of data and dashboards. We conclude that coordinated efforts and a call to action to ensure the standardization, storage, and maintenance of geospatial data for use on data dashboards and web maps are needed for long-term use, analyses, and monitoring to address current and future public health and other challenging issues.more » « less

The reproducibility and replicability (R&R) crisis poses a significant challenge across disciplines, particularly in spatiotemporal studies. This paper focuses on the unique challenges within spatiotemporal research in the context of R&R, including data availability, methodological conception transparency, interdisciplinary collaboration complexities, the balance between R&R and innovation, and R&R education. Recognizing the potential of Scientific Workflow Management Systems (SWMS) to enhance R&R, we introduce a pioneering SWMS-based integrated spatiotemporal research approach (SISRA) utilizing KNIME, an open-source SWMS, to tackle these R&R challenges. First, we developed a set of KNIME extensions, including Geospatial and Dataverse extensions, to enhance spatiotemporal software availability in SWMS. Then we created spatial data virtual laboratory architecture to support multidisciplinary collaboration. Finally, we suggested a geographical research lifecycle that integrates SWMS-based methods to improve practices, efficiency, and innovation in R&R research and education. Our approach exemplifies how executable workflows can not only alleviate the R&R burden on researchers but also strengthen R&R education in geographical research, illustrating the benefits of our approach in training, teaching, and multidisciplinary collaboration.more » « lessFree, publicly-accessible full text available February 10, 2026
