Null Controllability of a Nonlinear Age Structured Model for a Two-Sex Population

Abstract and Applied Analysis, 2021
This paper is devoted to study the null controllability properties of a nonlinear age and two-sex population dynamics structured model without spatial structure. Here, the nonlinearity and the couplage are at the birth level.

Simulating the impact of varying vegetation on West African monsoon surface fluxes using a regional convection-permitting model. [PDF]

Plant Environ Interact, 2023
Comparison between the use of varying vegetation fraction and fix vegetation fraction in regional climate models over West Africa: Case study of the Unified Model with focus on three different climatic zones. Abstract This study assessed the sensitivity of the West African climate to varying vegetation fractions.

Individual flowering phenology shapes plant–pollinator interactions across ecological scales affecting plant reproduction

Ecology and Evolution, Volume 13, Issue 1, January 2023., 2023
Using a farm‐scale experiment we investigated how intraspecific variation in flowering phenology and spatial heterogeneity in floral resources affected wild plant reproduction by modifying plant–pollinator interactions at the scale of the plant individual, the local assemblage, and the interaction network of agroecological infrastructures across the ...

A parametric sensitivity analysis for prioritizing regolith knowledge needs for modeling water transfers in the West African critical zone

Vadose Zone Journal, Volume 20, Issue 6, November/December 2021., 2021
Abstract Hard rock aquifers (HRAs) in West Africa (WA) are located within a thick regolith layer. The representation of thick tropical regolith in integrated hydrological models lacks consensus on aquifer geometries and parameter ranges. Our main objective was to determine the knowledge requirements on saturated hydraulic conductivity (Ks) to model the

Swell Generation Under Extra‐Tropical Storms

Journal of Geophysical Research: Oceans, Volume 126, Issue 9, September 2021., 2021
Abstract Storms propagate over the ocean and create moving patches of strong winds that generate swell systems. Here, we describe the dynamics of wave generation under a moving storm by using a simple parametric model of wave development, forced by a temporally and spatially varying moving wind field.

Lykaon, der Wolfsmann, und Mary Shelleys Frankenstein, or, The Modern Prometheus

Orbis Litterarum, Volume 76, Issue 2, Page 67-85, April 2021., 2021
Viele der rezenten Studien zur Ästhetik des Monströsen nehmen auf Michel Foucaults Vorlesungsreihe Les anormaux Bezug, in der er u. a. der diskursiven Transformation des Monsters von einem somatischen hin zu einem moralischen Abweichungsphänomen nachgeht.

A decision support tool to prioritize ballast water compliance monitoring by ranking risk of non‐indigenous species establishment

Journal of Applied Ecology, Volume 58, Issue 3, Page 587-595, March 2021., 2021
Partnerships between scientists and managers are essential for ensuring that best‐available science translates into effective adaptive management. Recognizing a need to inform ballast water management compliance inspections, a tool was created that automatically estimates relative risk of establishment of non‐indigenous species for arriving ships. This

Muli‐UWB Antenna System Design for 5G Wireless Applications with Diversity

Wireless Communications and Mobile Computing, Volume 2021, Issue 1, 2021., 2021
In this paper, we propose a compact Multiple Input Multiple Output (MIMO) antenna system with high isolation for wireless applications in 5G connected devices. This MIMO antenna system with the size of 92 × 88 mm2 consists of two elliptical antennas symmetrically arranged next to each other.
