Measurement of the volume CT dose index on spiral CT scanning with a real‐time ionization chamber

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 2, February 2026.
Abstract Background The measurement of computed tomography dose index 100 (CTDI100$CTD{{I}_{100}}$), which is feasible only through axial scanning, requires that the clinical spiral protocols be replaced with those for axial scanning. The real‐time ionization chamber detects the integral of radiation dose rate profile, enabling the direct verification ...

Geographical Distribution and Socio‐Economic Importance of Raphia ruwenzorica From South‐West of Burundi

open access: yesPlant-Environment Interactions, Volume 7, Issue 1, February 2026.
ABSTRACT The genus Raphia is among the commonly used and socio‐economically important plants in Africa. While Raphia ruwenzorica species is known to occur in Burundi, eastern Democratic Republic of Congo, Rwanda, and Uganda, its geographical distribution and socioeconomic importance are poorly documented in Burundi. This study maps R.

Multi‐Objective Robust Controller Synthesis With Integral Quadratic Constraints in Discrete‐Time

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 3, Page 935-954, February 2026.
ABSTRACT This article presents a novel framework for the robust controller synthesis problem in discrete‐time systems using dynamic Integral Quadratic Constraints (IQCs). We present an algorithm to minimize closed‐loop performance measures such as the ℋ∞$$ {\mathscr{H}}_{\infty } $$‐norm, the energy‐to‐peak gain, the peak‐to‐peak gain, or a ...

Time and phase alignment of distributed gateways: Theoretical analysis and experimental demonstration

open access: yesInternational Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 47-59, January/February 2026.
The performance limitation in multiple‐input multiple‐output (MIMO) feeder links due to time and phase misalignment of the ground stations is investigated. Time and phase distribution over optical fiber is considered as an approach to achieve the synchronization requirements.
