Topological Design and Modulation Strategy for Buck-Boost Three-Level Inverters

, 2009
Udgivelsesdato: JulyTo date, designed topologies for dc-ac inversion with both voltage buck and boost capabilities are mainly focused on two-level circuitries with extensions to three-level possibilities left nearly unexplored.

Copy Number Variation‐Based Molecular Sexing of Ixodes scapularis and Rhipicephalus microplus Immature Stages Using qPCR and ddPCR Approaches

Ecology and Evolution, Volume 16, Issue 11, November 2026.
We developed and validated a copy number variation (CNV)‐based molecular method to accurately determine the sex of immature ticks, Ixodes scapularis and Rhipicephalus microplus, which lack morphological sexual dimorphism. Using qPCR and ddPCR assays targeting female‐enriched genes, sex was reliably identified from DNA extracted non‐destructively from a

Modified modulation scheme of the buck-boost voltage source inverter for bidirectional power flow capability

, 2015
Single-stage DC-AC power converters are gaining higher popularity due to their merits compared to the conventional two-stage DC-AC conversion systems. One of these converters is the buck-boost voltage source inverter.

The Politics of Research Ethics: Examining Institutional Consent as an Extractivist Practice within Research in Rural Northern Communities

Symbolic Interaction, Volume 49, Issue 4, Page 896-914, November 2026.
University Research Ethics Boards (REBs) in Canada are intended to protect research participants, but standardized ethics procedures can be poorly suited to relational, community‐led, action‐oriented, and Indigenous research. This article examines how institutional consent practices can reproduce extractive paradigms when they are applied to research ...
