Recommendations on bioacoustical metrics relevant for regulating exposure to anthropogenic underwater sounda).

Metrics to be used in noise impact assessment must integrate the physical acoustic characteristics of the sound field with relevant biology of animals. Several metrics have been established to determine and regulate underwater noise exposure to aquatic fauna. However, recent advances in understanding cause-effect relationships indicate that additional metrics are needed to fully describe and quantify the impact of sound fields on aquatic fauna.

Verification of a Novel Minimally Invasive Device for the Isolation of Rare Circulating Tumor Cells (CTC) in Cancer Patients' Blood.

Circulating tumor cells (CTCs) exist in low quantities in the bloodstream in the early stages of cancers. It, therefore, remains a technical challenge to isolate them in large enough quantities for a precise diagnosis and downstream analysis. We introduce the BMProbe™, a minimally invasive device that isolates CTCs during a 30-minute incubation in the median cubital vein.

Opportunities to tackle structural racism and ethnicity-based discrimination in recovering and rebuilding from the COVID-19 pandemic.

The impact of COVID-19 has been disproportionately felt by populations experiencing structural racial- and ethnicity-based discrimination. Here, we describe opportunities for COVID-19 response and recovery efforts to help build more equal and resilient societies, through investments in: (i) interventions focused on explicitly addressing racial and ethnicity-based discrimination; (ii) interventions supporting the delivery of universal services, and in ways that address compounding and intersecting drivers of exclusion and marginalization; and (iii) cross-cutting enabling measures, such as participatory mechanisms and data disaggregation.

International harmonization of procedures for measuring and analyzing of vessel underwater radiated noise.

The habitat of the endangered southern resident killer whale (SRKW) overlaps major international shipping lanes near the Port of Vancouver, British Columbia. Shipping is a dominant source of underwater noise, which can hinder SRKW key life functions. To reduce environmental pressure on the SRKWs, Vancouver Fraser Port Authority offers incentives for quieter ships.

Selection on + + ⋯ + via Cartesian product trees.

Selection on the Cartesian product is a classic problem in computer science. Recently, an optimal algorithm for selection on  + , based on soft heaps, was introduced. By combining this approach with layer-ordered heaps (LOHs), an algorithm using a balanced binary tree of  +  selections was proposed to perform selection on  +   + ⋯ +  in (⋅ + ⋅), where have length .
