Persistent Persister Misperceptions [PDF]
Frontiers in Microbiology, 2016 Persister cells survive antibiotic treatment due to their lack of metabolism, rather than through genetic change, as shown via four seminal experiments conducted by the discoverers of the phenotype (Hobby et al., 1942; Bigger, 1944). Unfortunately, over seven decades of persister cell research, the literature has been populated by misperceptions that ...

Economics & Human Biology, 2021 We ask whether mortality from historical pandemics has any predictive content for mortality in the Covid-19 pandemic. We find strong persistence in public health performance. Places that performed worse in terms of mortality in the 1918 influenza pandemic also have higher Covid-19 mortality today.

Journal of Pure and Applied Algebra, 2021 In this paper we introduce the persistent magnitude, a new numerical invariant of (sufficiently nice) graded persistence modules. It is a weighted and signed count of the bars of the persistence module, in which a bar of the form $[a,b)$ in degree $d$ is counted with weight $(e^{-a}-e^{-b})$ and sign $(-1)^d$.

Persistently Finite, Persistently Arithmetic Theories [PDF]
Proceedings of the American Mathematical Society, 1983 The main result shows that a certain class of theories, the persistently finite, persistently arithmetic theories, have only arithmetic countable models.

Persistent triangulations [PDF]
Journal of Functional Programming, 2001 Triangulations of a surface are of fundamental importance in computational geometry, computer graphics, and engineering and scientific simulations. Triangulations are ordinarily represented as mutable graph structures for which both adding and traversing edges take constant time per operation.

Is Persistent Memory Persistent? [PDF]
Queue, 2020 Power failures pose the most severe threat to application data integrity, and painful experience teaches that the integrity promises of failure-atomic update mechanisms can’t be taken at face value. Diligent developers and operators insist on confirming integrity claims by extensive firsthand tests.

Cell, 2021 The highly effective and safe mRNA-based severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines draw on decades of painstaking research to overcome the many hurdles for delivering, expressing, and avoiding toxicity of therapeutic mRNA. Cell editor Nicole Neuman talked with Dr. Katalin Karikó and Dr.

Modeling and analysis of a stochastic giving-up-smoking model with quit smoking duration
Mathematical Biosciences and Engineering, 2023 Smoking has gradually become a very common behavior, and the related situation in different groups also presents different forms. Due to the differences of individual smoking cessation time and the interference of environmental factors in the spread of ...
