To Double Stick or Not to Double Stick?

To react or not to react? Intrinsic stochasticity of human control in virtual stick balancing

Understanding how humans control unstable systems is central to many research problems, with applications ranging from quiet standing to aircraft landing. Increasingly, much evidence appears in favour of event-driven control hypothesis: human operators only start actively controlling the system when the discrepancy between the current and desired system states becomes large enough. The event-dr...

Forcing cells to stick around

eukocytes have a better chance of sticking to neighboring cells with the right ligands if they rotate on their way by, based on results from Dwir et al. (page 649). Flowing leukocytes are captured via L-selectin interactions with carbohydrate ligands on vessel walls and subsets of other leukocytes. L-selectin is an unusual adhesive molecule—shear stress improves its adherance to ligands, wherea...

Glow stick or urine sample?

The random urine sample shown in Fig. 1 was collected from a 43-year-old woman with systemic lupus erythematosus. A routine urinalysis (Aution Max AX-4280; Iris Diagnostics) revealed no remarkable findings and, specifically, was negative for protein. The corresponding urine protein concentration, however, was 448 mg/dL (reference interval, 12 mg/dL) as measured with a turbidimetric assay (Cobas...

Stick To What You Know

I will start by describing two broad classes of allegedly justified beliefs that do not constitute knowledge and which, hence, cannot be what they are often taken to be if my view is correct.
