JUMP AROUND, JUMP AROUND: TRANSPOSABLE ELEMENT ACTIVATION IN NEURODEGENERATIVE TAUOPATHY

Airflow elicits a spider's jump towards airborne prey. I. Airflow around a flying blowfly.

The hunting spider Cupiennius salei uses airflow generated by flying insects for the guidance of its prey-capture jump. We investigated the velocity field of the airflow generated by a freely flying blowfly close to the flow sensors on the spider's legs. It shows three characteristic phases (I-III). (I) When approaching, the blowfly induces an airflow signal near the spider with only little flu...

Neurodegenerative tauopathy in the worm.

T he most common neurodegenerative diseases are characterized by the presence of abnormal filamentous protein inclusions in nerve cells of the brain. In Alzheimer’s disease, these inclusions are made of hyperphosphorylated tau protein (1). Together with the extracellular -amyloid deposits, they constitute the defining neuropathological characteristics of Alzheimer’s disease. Tau inclusions, in ...

Jump-independent approximation in conforming and nonconforming finite element spaces

A counterexample is given. It confirms that the conforming finite element is inappropriate for singular problems with large coefficient jumps. The Scott-Zhang operator is applied to a nonconforming finite element. It is shown that the nonconforming finite element provides the optimal order approximation in interpolation, in L-projection, and in solving elliptic differential equation, independen...

Model Free Jump Measures and Interest Rates: Common Patterns in US and UK Monetary Policy around Major Economic Events

We employ model-free jump measures to study monetary policy operations in the US and UK around major economic events by exploiting the relationship between jumps, interest rates, and macroeconomic news releases related to monetary policy. In our analysis, we explicitly account for the timing of jumps in US and UK interest rates and the correlation across jumps in the same two interest rates and...
