We observed exact dynamic localization in its general case in strongly coupled curved waveguide arrays with periodic, nonsquare-wave curvatures. We achieved a six times change in the dynamic localization bandwidth by changing a design parameter in our deviated-square-wave curvature. By analyzing the relation between the bandwidth and curvature profile, we offer a general method to control the localization bandwidth.

The cytoplasm exhibits viscoelastic properties, displaying both solid and liquid-like behavior, and can actively regulate its mechanical attributes. The cytoskeleton is a major regulator among the numerous factors influencing cytoplasmic mechanics. We explore the interdependence of various cytoskeletal filaments and the impact of their density on cytoplasmic viscoelasticity.

Insular species are usually endemic and prone to long-term population reduction, low genetic diversity, and inbreeding depression, which results in difficulties in species conservation. The situation is even more challenging for the glacial relict species whose habitats are usually fragmented in the mountainous regions. is an endangered and endemic relict tree species in Taiwan.

Background: During the SARS-CoV-2 pandemic, dominant viral variants were repeatedly replaced by new variants with altered properties, frequently changing the dynamics of the infection event, as well as the effectiveness of vaccines and therapeutics. SARS-CoV-2 variant monitoring by whole genome sequencing was established at the University Medical Center Mainz, Germany to support patient management during the pandemic.

Methods: SARS-CoV-2 RNA samples from the University Medical Center were analysed weekly with whole genome sequencing.

This work deals with the strain-rate dependent characterization of paper under uniaxial tension at high strain-rates. Experiments were performed involving a Split Hopkinson bar for high strain-rate testing, comparing the results with conventional quasi-static tests. Tests were conducted in a strain-rate range between 0.

The distinct timescales of synaptic plasticity and neural activity dynamics play an important role in the brain's learning and memory systems. Activity-dependent plasticity reshapes neural circuit architecture, determining spontaneous and stimulus-encoding spatiotemporal patterns of neural activity. Neural activity bumps maintain short term memories of continuous parameter values, emerging in spatially organized models with short-range excitation and long-range inhibition.
