When Does Alzheimer's Disease Start? Plasma Aβ42/40 Assays Show Steep Changes at Aβ‐PET Centiloid 15, Mean Age of 66 Years

open access: yesAnnals of Neurology, EarlyView.
Objective Sporadic late‐onset Alzheimer's disease (AD) is characterized by a long pre‐clinical phase where amyloid‐beta (Aβ) and tau begin to accumulate in the brain. The primary objective was to determine the age at which AD starts by finding the average population age when both positron emission tomography (PET) Aβ (Aβ‐PET) and plasma Aβ42/40 become ...

Individualized Atrophy‐Based Prediction of Dementia Progression in Familial Frontotemporal Lobar Degeneration With Bayesian Linear Mixed‐Effects Modeling

open access: yesAnnals of Neurology, EarlyView.
Objective Age of symptom onset is highly variable in familial frontotemporal lobar degeneration (f‐FTLD). Accurate prediction of onset would inform clinical management and trial enrollment. Prior studies indicate that individualized maps of brain atrophy can predict conversion to dementia in f‐FTLD.

Discorrelated quantum states

open access: yes, 2017
The statistical properties of photons are fundamental to investigating quantum mechanical phenomena using light. In multi-photon, two-mode systems, correlations may exist between outcomes of measurements made on each mode which exhibit useful properties.

Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

open access: yesThe Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

A Meta-Analysis of the Joint Simon Effect

open access: yes, 2017
Since its design in 2003, the joint Simon task and corollaryjoint Simon effect (JSE) have been invaluable tools towardsthe study of joint action and the understanding of howindividuals represent the action/task of a co-actor. Thepurpose of this meta-analysis was to systematically andquantitatively review the sizeable behavioural evidence forthe JSE ...
