Cognitive Models for Machine Theory of Mind.

Some of the required characteristics for a true machine theory of mind (MToM) include the ability to (1) reproduce the full diversity of human thought and behavior, (2) develop a personalized model of an individual with very limited data, and (3) provide an explanation for behavioral predictions grounded in the cognitive processes of the individual. We propose that a certain class of cognitive models provide an approach that is well suited to meeting those requirements. Being grounded in a mechanistic framework like a cognitive architecture such as ACT-R naturally fulfills the third requirement by mapping behavior to cognitive mechanisms.

Rate of non-metastatic solid tumor progression following critical illness: a prospective cohort study of UK Biobank participants.

Objective: To determine whether admission to critical care is associated with subsequent disease progression in patients with non-metastatic solid tumors.

Methods: This observational cohort study of UK Biobank participants identified those diagnosed with solid tumors and survived hospitalization. Two cohorts were identified based on critical care admission and new metastatic disease as reported at UK Biobank follow-up visits, or primary or secondary care records were compared.

The effect of small increases in blood glucose on insulin secretion and endogenous glucose production in humans.

Small glycemic increments (≤0.5 mmol/L) can exert suppressive actions on endogenous glucose production (EGP) however it is unclear if this is an insulin dependent or independent process. Here, we performed a low-rate glucose infusion in control participants without diabetes and in people with type 1 diabetes (T1D) to better understand this phenomenon.
