Construction of approximate invariants for nonintegrable Hamiltonian systems
Udgivet 2025-07-01Få fuldtekstWe present a method to construct high-order polynomial approximate invariants (AI) for nonintegrable Hamiltonian dynamical systems and apply it to a modern ring-based particle accelerator. Taking advantage of a special property of one-turn transformation maps expressed as square matrices, AIs can be...

RIS Assisted UAV for Weather-Dependent Satellite Terrestrial Integrated Network With Hybrid FSO/RF Systems
Udgivet 2023-01-01Få fuldtekstIn this paper, we investigate the performance of hybrid free-space optical (FSO) and radio frequency (RF) relay systems in satellite terrestrial integrated network where the effect of weather conditions is taking into consideration. Specifically, we design three different relay schemes in different...

The microbiome interacts with the circadian clock and dietary composition to regulate metabolite cycling in the Drosophila gut
Udgivet 2025-07-01Få fuldtekstThe gut microbiome plays a key role in the maintenance of host metabolic homeostasis and health. Most metabolic processes cycle with a 24-hour rhythm, but the extent to which the microbiome influences metabolite cycling under different conditions, such as variations in dietary composition, remains l...

Assessing the utility of genomic selection to breed for durable Ascochyta blight resistance in chickpea
Udgivet 2025-06-01Få fuldtekstAbstract Ascochyta blight (AB) is one of the most devastating fungal diseases of chickpea (Cicer arietinum L.). Conventional breeding has focused on exploiting and introgressing major genes (qualitative effect) to improve AB resistance in released varieties. However, such approaches are time‐consumi...
