- Heart failure (HF) is a well-described final common pathway for a broad range of diseases however substantial confusion exists regarding how to describe, study, and track these underlying etiologic conditions. We describe (1) the overlap in HF etiologies, comorbidities, and case definitions as currently used in HF registries led or managed by members of the global HF roundtable; (2) strategies to improve the quality of evidence on etiologies and modifiable risk factors of HF in registries; and (3) opportunities to use clinical HF registries as a platform for public health surveillance, implementation research, and randomized registry trials to reduce the global burden of noncommunicable diseases. Investment and collaboration among countries to improve the quality of evidence in global HF registries could contribute to achieving global health targets to reduce noncommunicable diseases and overall improvements in population health.

- On-demand droplet generation from a continuously flowing stream of aqueous phase has profound applications in dropletbased microfluidics for rare event encapsulation studies. Here, we present acoustic relocation-based droplet generation from co-flowing immiscible fluids in an on-demand manner using bulk acoustic wave (BAW). After on-demand droplet generation, droplets are isolated using the same acoustic force resulted from BAW. Two different acoustic relocation regimes are observed, namely, stream to droplet relocation and stream to stream relocation regime. Our experimental observation reveals that to generate droplets from co-flowing fluids, the following conditions must be satisfied. First, the co-flowing immiscible stream should be maintained in acoustic relocation conditions (Cac > 1); Second, the capillary instability should be triggered during the relocation process, which happens at capillary numbers of the co-flowing fluids should be less than 0.2 (CaL and CaH < 0.2). Finally, using BAW microfluidic chip, droplets containing microparticle were produced ondemand from co-flowing streams wherein the microparticles are added in one of the phases.

- E-motors are characterized by their high-frequency content. This brings a new challenge for a technology such as Component-based Transfer Path Analysis. This paper will intend to show how this modular methodology has been applied for a wiper e-motor. The source is characterized in-situ by a set of blocked forces and alternatively with pseudo forces. Afterward, the independent loads are converted to contact forces using a Frequency Based Substructuring technique, allowing assembly definition and target prediction on a different receiver. Finally, the predicted vibrations on the target assembly are compared to the measured one for validation purposes. A dedicated high-frequency shaker was developed to meet the required data quality. In this way the substructuring technique was applicable in a wide frequency range up to 5 kHz.
