Durable scalable 3D SLA-printed cuff electrodes with high performance carbon + PEDOT:PSS-based contacts.

Background: The stimulation and recording performance of implanted neural interfaces are functions of the physical and electrical characteristics of the neural interface, its electrode material and structure. Therefore, rapid optimization of such characteristics is becoming critical in most clinical and research studies. This paper describes the development of an upgraded 3D printed cuff electrode shell design containing a novel intrinsically conductive polymer (ICP) for stimulation and recording of peripheral nerve fibers.

Crop insurance: A barrier to conservation adoption?

Midwest corn producers face inherent risks in their daily operations and incorporate risk-management strategies to reduce uncertainty; among these, crop insurance has dominated the agricultural landscape for decades. Previous research on conservation adoption has primarily examined the impact of individual-level characteristics on adoption, yet little is known about the impact of external factors, such as crop insurance. Using a mixed-methods approach, we conducted semi-structured interviews and a multi-state survey to determine if crop insurance requirements limit cover crops and/or conservation tillage adoption for Midwest corn producers.

Why metrics matter: evaluating policy choices for reactive nitrogen in the Chesapeake Bay watershed.

Despite major efforts, the reduction of reactive nitrogen (Nr) using traditional metrics and policy tools for the Chesapeake Bay has slowed in recent years. In this article, we apply the concept of the Nitrogen Cascade to the chemically dynamic nature and multiple sources of Nr to examine the temporal and spatial movement of different forms of Nr through multiple ecosystems and media. We also demonstrate the benefit of using more than the traditional mass fluxes to set criteria for action.
