ON TESTIMONY AND TRANSMISSION [PDF]

open access: yesEpisteme, 2014
AbstractJennifer Lackey's case “Creationist Teacher,” in which students acquire knowledge of evolutionary theory from a teacher who does not herself believe the theory, has been discussed widely as a counterexample to so-called transmission theories of testimonial knowledge and justification.

Transmission of Prions [PDF]

open access: yesThe Journal of Infectious Diseases, 2002
The “protein only” hypothesis states that the infectious agent causing transmissible spongiform encephalopathies is a conformational isomer of PrP, a host protein predominantly expressed in brain, and is strongly supported by many lines of evidence. Prion diseases are so far unique among conformational diseases in that they are transmissible, not only ...

Severe Acute Respiratory Syndrome Coronavirus 2 Variants of Concern: A Perspective for Emerging More Transmissible and Vaccine-Resistant Strains

open access: yesViruses, 2022
Novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern (VOC) are constantly threatening global public health. With no end date, the pandemic persists with the emergence of novel variants that threaten the effectiveness of ...

Transmissibility Matrix in Harmonic and Random Processes [PDF]

open access: yes, 2004
The transmissibility concept may be generalized to multi-degree-of-freedom systems with multiple random excitations. This generalization involves the definition of a transmissibility matrix, relating two sets of responses when the structure is subjected ...

Analysis on the Dynamic Wave Attenuation Properties of Metaconcrete Considering a Quasi-Random Arrangement of Inclusions

open access: yesFrontiers in Materials, 2021
The mitigation properties of metaconcrete cast with two types of resonant inclusions are assessed through wave transmission tests. Three cylindric metaconcrete specimens of regular size (20 cm height, 10 cm diameter), containing an equal number of ...

Assessing the Impacts of Meteorological Factors on COVID-19 Pandemic Using Generalized Estimating Equations

open access: yesFrontiers in Public Health, 2022
BackgroundMeteorological factors have been proven to affect pathogens; both the transmission routes and other intermediate. Many studies have worked on assessing how those meteorological factors would influence the transmissibility of COVID-19.

Containing the Transmission of COVID-19: A Modeling Study in 160 Countries

open access: yesFrontiers in Medicine, 2021
Background: It is much valuable to evaluate the comparative effectiveness of the coronavirus disease 2019 (COVID-19) prevention and control in the non-pharmacological intervention phase of the pandemic across countries and identify useful experiences ...

Variations in O-Glycosylation Patterns Influence Viral Pathogenicity, Infectivity, and Transmissibility in SARS-CoV-2 Variants

open access: yesBiomolecules, 2023
The highly glycosylated S protein plays a vital role in host cell invasion, making it the principal target for vaccine development. Differences in mutations observed on the spike (S) protein of SARS-CoV-2 variants may result in distinct glycosylation ...

Millifluidic Synthesis of Core–Shell Resonators For Tunable Sonic BandGaps in Acoustic Metamaterials

open access: yesAdvanced Materials Interfaces, EarlyView.
Millimeter‐scale core–shell acoustic resonators are fabricated by a gravity‐assisted dripping approach and incorporated into epoxy composites at controlled volume fractions. The resulting alumina–core resonator composites show tunable low‐frequency acoustic attenuation, demonstrating a scalable route for integrating locally resonant metamaterial units ...

pH‐Driven Two‐Stage Conformational Switching Activates an Acid‐Responsive Chaperone

open access: yesAngewandte Chemie, EarlyView.
AchC is an ATP‐independent, pH‐responsive chaperone. AchC functions as a molecular switch, sensing pH changes and undergoing a two‐stage conformational transition: C‐terminal extension (colored in yellow) loosening at mild pH 4.0–5.5 and monomerization at strong acidic pH 3.0.
