DOI: 10.1016/j.ecolind.2020.106828
Abstract: Abstract Theoretically, both land fragmentation and consolidation (defragmentation) approaches are considered as tools of land management. However, although a large literature about the relationships among land fragmentation, land consolidation, agriculture production and crops diversification concepts… read more here.

DOI: 10.1016/j.yofte.2017.11.019
Abstract: Abstract By employing sophisticated routing and spectrum assignment (RSA) algorithms together with a finer spectrum granularity (namely frequency slot) in resource allocation procedures, flex-grid optical networks can accommodate diverse kinds of services with high spectrum-allocation… read more here.

DOI: 10.1109/jlt.2019.2924914
Abstract: Dynamic traffic in optical networks leads to spectrum fragmentation, which significantly reduces network performance, i.e., increases blocking rate and reduces spectrum usage. Telecom operators face the operational challenge of operating non-disruptive defragmentation, i.e., within the… read more here.

DOI: 10.3389/fcvm.2022.942998
Abstract: Introduction Atrial fibrillation (AF) is a heritable disease, and the paired-like homeodomain transcription factor 2 (PITX2) gene is highly associated with AF. We explored the differences in the circumferential pulmonary vein isolation (CPVI), which is… read more here.
