Background: The majority of countries in sub-Saharan Africa are ill-prepared to address the rising burden of cancer. While some have been able to establish a single cancer referral center, few have been able to scale-up services nationally towards universal health coverage. The literature lacks a step-wise implementation approach for resource-limited countries to move beyond a single-facility implementation strategy and implement a national cancer strategy to expand effective coverage. Methods: We applied an implementation science framework, which describes a four-phase approach: Exploration, Preparation, Implementation, and Sustainment (EPIS). Through this framework, we describe Rwanda’s approach to establish not just a single cancer center, but a national cancer program. Results: By applying EPIS to Rwanda’s implementation approach, we analyzed and identified the implementation strategies and factors, which informed processes of each phase to establish foundational cancer delivery components, including trained staff, diagnostic technology, essential medicines, and medical informatics. These cancer delivery components allowed for the implementation of Rwanda’s first cancer center, while simultaneously serving as the nidus for capacity building of foundational components for future cancer centers. Conclusion: This “progressive scaling” approach ensured that initial investments in the country’s first cancer center was a step toward establishing future cancer centers in the country.

PEBB (power electronics building block) systems are typical nonlinear systems. Under the conventional but still popular linear control design, the system stability margin varies from one operating point to another. This paper introduces a novel approach to monitoring the DC bus stability margin of a PEBB system online. At the steady state of the system, a small-signal perturbation current î p is injected into the DC bus, and the load-side response current î L is measured. By checking the validation |î L ( jw)| < |î p ( jw)|, the system stability margin can be examined. Experiments on a 48 V DC DPS demonstrate the proposed measurement approach. An implementation approach is also proposed for an 800 V DC PEBB-based testbed system.
