‘The training was intense but rewarding’

Serotonin: Waiting but Not Rewarding

A new study in mice demonstrates that stimulating dorsal raphe serotonin boosts patient waiting but stimulation itself is not rewarding. Dorsal raphe serotonin's unique contribution provides a neural locus for impulsivity and related failures of patience.

Mentoring--hard and underappreciated but rewarding.

It was logical but was it the whole truth?

Calcific aortic stenosis (AS) was initially characterized as a degenerative process (disorder) because of a tendency to describe any disorder that was not well understood and often occurred in the ‘elderly’ as degenerative. In the last ‘15–20’ years, the observation of the presence of risk factors for arterial atherosclerosis in patients with calcific AS, the production of aortic valve calcific...

Hydration during intense exercise training.

Hydration status has profound effects on both physical and mental performance, and sports performance is thus critically affected. Both overhydration and underhydration - if sufficiently severe - will impair performance and pose a risk to health. Athletes may begin exercise in a hypohydrated state as a result of incomplete recovery from water loss induced in order to achieve a specific body mas...

It was the training data pruning too!

We study the current best model (Krishnamurthy et al., 2017) (KDG) for question answering on tabular data evaluated over the WIKITABLEQUESTIONS dataset. Previous ablation studies performed against this model attributed the model’s performance to certain aspects of its architecture. In this paper, we find that the model’s performance also crucially depends on a certain pruning of the data used t...
