Funding hiccup at Jodrell

Polarisation Observations at Jodrell Bank Observatory

Some of the issues concerning polarisation calibration in the context of pulsar observations are outlined along with the existing calibration system in Jodrell Bank Observatory. The principle behind the back-calibration of the Jodrell Bank database of 16 years is presented along with plans for exploiting the database in the future.

Why do we hiccup?

Why do we hiccup? Considering the fact that almost everyone experiences hiccups at one time or another, remarkably little is known about them. The name itself is onomatopoeic, which is appropriate considering that the only common understanding of the hiccup is of the characteristic sound. Hiccups can be predictably elicited in some individuals by overindulgence of food, alcohol, or both, someti...

The Caltech–Jodrell Bank VLBI Surveys

The Caltech–Jodrell Bank VLBI surveys of bright extragalactic radio sources north of declination 35 were carried out between 1990 and 1995 using the Mark-II system, achieving images with a resolution of about 1 mas at 5 GHz. The CJ1 survey (together with the older ‘PR’ survey) includes 200 objects with 5 GHz flux density greater than 0.7 Jy; the CJ2 survey includes 193 flat-spectrum sources wit...

A Case of Persistent Hiccup

Linkage of hiccup with heartbeat.

We explored a possible link between the cardiac cycle and the timing of recurrent hiccups in 10 patients with chronic, intractable hiccups. Recordings made during daytime naps in a sleep laboratory included sleep state; electrocardiogram; and respiration by means of a thermistor to detect airflow, bands around the rib cage and abdomen to assess expansion, and a bipolar surface electrode electro...
