Ear candling is an alternative medicine practice alleged to enhance general health by putting an end of a hollow candle in the ear canal and lighting up the other end of it. It also is advertised for cerumen and debris (bacteria and fungi) removal. Ear candling is claimed to create negative pressure for drawing cerumen from the ear and to benefit the ears in many ways. It is however not free o...

BACKGROUND The use of perforator flaps has allowed for the transfer of large amounts of soft tissue with decreased morbidity. For breast reconstruction, the deep inferior epigastric perforator flap, the superior and inferior gluteal artery perforator flaps, and the transverse upper gracilis flap are all options. The authors present an alternative source using posterior thigh soft tissue based o...

Examination of the lumbar cerebrospinal fluid in the diagnosis of cerebral tumour is less often resorted to than formerly, partly because in some instances there may be a risk of coning after lumbar puncture, but more especially because arteriography and ventriculography are now more frequently used for locating the tumour and examination of the ventricular fluid is often found to be more conve...

A spatial time series dataset is a collection of time series, each referencing a location in a common spatial framework. Correlation analysis is often used to identify pairs of potentially interacting elements from the cross product of two spatial time series datasets. However, the computational cost of correlation analysis is very high when the dimension of the time series and the number of lo...

We prove that all hierarchically hyperbolic groups have nite asymptotic dimension. One application of this result is to obtain the sharpest known bound on the asymptotic dimension of the mapping class group of a nite type surface: improving the bound from exponential to at most quadratic in the complexity of the surface. We also apply the main result to various other hierarchically hyperbolic g...

A yo-yo-type wire-boom deployment system has been developed and flight tested on a sounding rocket mission. The goal of the work has been to validate a new mechanism that rapidly deploys wire booms from a spinning spacecraft. This work takes a theoretical system design and implements it in practical hardware. The limitations inherent in practical hardware necessitated new theoretical developmen...
