Underestimation of COVID-19 mortality during the pandemic
Background There has been considerable international variation in mortality during the COVID-19 pandemic. The objective of this study was to investigate the differences between mortality registered as due to COVID-19 and the excess all-cause mortality ...

The Underestimation Of Egocentric Distance: Evidence From Frontal Matching Tasks [PDF]
There is controversy over the existence, nature, and cause of error in egocentric distance judgments. One proposal is that the systematic biases often found in explicit judgments of egocentric distance along the ground may be related to recently observed

Electronic friction-based vibrational lifetimes of molecular adsorbates: Beyond the independent atom approximation [PDF]
We assess the accuracy of vibrational damping rates of diatomic adsorbates on metal surfaces as calculated within the local-density friction approximation (LDFA).

Vast (but avoidable) underestimation of global biodiversity.
The number of species on Earth is highly uncertain. A recent study has suggested that there are less than 2 million prokaryotic species on Earth; this Formal Comment suggests instead that there are more likely hundreds of millions or billions of species,

Modified estimator of the contribution rates of population eigenvalues [PDF]
Modified estimators for the contribution rates of population eigenvalues are given under an elliptically contoured distribution. These estimators decrease the bias of the classical estimator, i.e. the sample contribution rates.

Antimatter underestimated [PDF]
We warn of the potential nuclear proliferation's consequences of military applications of nano- or microgram amounts of antimatter, such as triggering of high-yield thermonuclear explosions, laser pumping, compact sources of energy, directed-energy beams, and portable sources of muons.

Fast approximation of visibility dominance using topographic features as targets and the associated uncertainty [PDF]
An approach to reduce visibility index computation time andmeasure the associated uncertainty in terrain visibility analysesis presented. It is demonstrated that the visibility indexcomputation time in mountainous terrain can be reduced substantially ...
