Monitoring the Path to the Elimination of Infectious Diseases
Tropical Medicine and Infectious Disease, 2017 During the endgame of elimination programs, parasite populations may exhibit dynamical phenomena not typical of endemic disease. Particularly, monitoring programs for tracking infection prevalence may be hampered by overall rarity, the sporadic and ...

Hot cosmic qubits: late-time de Sitter evolution and critical slowing down
Journal of High Energy Physics, 2020 Temporal evolution of a comoving qubit coupled to a scalar field in de Sitter space is studied with an emphasis on reliable extraction of late-time behaviour.

Accelerating ultrafast magnetization reversal by non-local spin transfer
Nature Communications, 2023 Under laser illumination it is possible to drive a ferromagnet to lose its magnetization. While this process can be rapid, remagnetization following this is slower, due to the universal critical slowing down near the phase transition.

Critical slowing down and hyperuniformity on approach to jamming
Physical Review E, 2016 Hyperuniformity characterizes a state of matter that is poised at a critical point at which density or volume-fraction fluctuations are anomalously suppressed at infinite wavelengths. Recently, much attention has been given to the link between strict jamming and hyperuniformity in frictionless hard-particle packings. Doing so requires one to study very

Critical Slowing Down Near Topological Transitions in Rate-Distortion Problems [PDF]
, 2021 In rate-distortion (RD) problems one seeks reduced representations of a source that meet a target distortion constraint. Such optimal representations undergo topological transitions at some critical rate values, when their cardinality or dimensionality ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

NON CRITICAL SLOWING DOWN IN OPTICAL BISTABILITY
Le Journal de Physique Colloques, 1988 We report on the switching dynamics of a bistable device in the case when a holding power maintains the system in a stable state of the lower branch and a pulse address of finite duration (T) brings it close to the unstable state of the middle branch. For a critical pulse duration (Tc) the pulse exactly brings the device in the unstable state where it ...

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
