recommendations! Published in 2025 at "Advanced Science"

DOI: 10.1002/advs.202416305

Abstract: Metal filamentation based mechanisms have the advantage of a high switching current ratio, yet typically require high switching voltages to activate the memristive device due to the primary mechanism of atomic vacancy filling and movement.… read more here.

DOI: 10.1016/j.optcom.2017.02.063

Abstract: Abstract The spatiotemporal dynamics of femtosecond filamentation were investigated numerically to evaluate various intensity distributions of zero-order Mathieu beams without the phase alteration for adjacent lobes. The side filaments are formed due to constructive interferences… read more here.

DOI: 10.1016/j.optcom.2018.12.039

Abstract: Abstract An intense laser would suffer nonlinear effects during its propagation in plasma, which greatly affects the illumination uniformities of laser beams in a hohlraum for ignition. Based on the theory of the relativistic and… read more here.

DOI: 10.1063/5.0205253

Abstract: Reversible energy conversion between magnetic and kinetic energies has been recently demonstrated in a system of counterstreaming electron beams [see A. Ghizzo et al., Phys. Rev. Lett. 131, 035101 (2023)]. During the first step of… read more here.

DOI: 10.1088/1361-6587/abe695

Abstract: A semi-Lagrangian relativistic Vlasov–Maxwell solver is used to describe the non-linear momentum transfer between electron beams, which is driven by spontaneous fluctuations in the oblique filamentation instability (a type of Weibel mode) in two-dimensional plasmas.… read more here.

DOI: 10.1093/femsyr/foac060

Abstract: Abstract The yeast Saccharomyces cerevisiae, also known as brewer's yeast, can undergo a reversible stress-responsive transition from individual ellipsoidal cells to chains of elongated cells in response to nitrogen- or carbon starvation. Whole colony morphology… read more here.

DOI: 10.1103/physreve.111.024410

Abstract: Bacterial aggregate formation and surface accumulation are increasingly viewed as alternative pathways for biofilm colonization. However, little is known about the dynamics of bacterial aggregate cluster-cluster assembly and their subsequent microstructural and mechanical properties. To… read more here.

DOI: 10.1128/iai.00600-24

Abstract: ABSTRACT The diameter, length, and shape of bacteria are maintained with such high fidelity that these parameters are classically used as metrics in the distinction of bacterial species. Increasing evidence indicates that bacteria transiently shift… read more here.

DOI: 10.1128/jb.00646-20

Abstract: Filamentation is an important biological mechanism that aids in the survival, pathogenesis, and antibiotic resistance of bacteria within different environments, including pathogenic bacteria such as uropathogenic Escherichia coli. Here, we have identified a bacteriophage-encoded cell… read more here.

DOI: 10.1128/mbio.02135-18

Abstract: For the ubiquitous environmental pathogen Cryptococcus neoformans, the morphological transition from yeast to filament confers resistance to natural predators like soil amoeba and is an integral differentiation event to produce infectious spores. Interestingly, filamentation is… read more here.
