Burrows Permeameter
No full textThis instrument, used for determining the normal magnetic induction curve and the hysteresis loop for a straight round specimen, was designed by Charles W. Burrows of the National Bureau of Standards around 1909, utilizing the idea of a distributed and adjustable magnetomotive force. Its magnetic circuit consists of two approximately identical bars 250 millimeters long, their ends being clamped by brass screws in two connecting yokes of high permeability. Yoke ends are hemispherical to minimize flux leakage into air. The main magnetizing solenoids consist of 10 layers of No. 18 copper wire wound with 7.958 turns per centimeter. They extend over the entire length of the two bars between the yokes. A compensating coil with four windings in series is added at the four ends. The main test coil is wound closely over the middle quarter of the bar chosen as a test specimen. On each side of this, midway between it and the yokes, the two halves of a second search coil are wound. A third16 x 35 x 20 c

Politics - talk by Jonathan Burrows
No full textSUMMARYPolitics was a research talk written for the Inventur#2–Contemporary Dance and Performance Conference at Tanzhaus NRW Düsseldorf, June 2nd 2017. This talk formed part of a panel on Social Practices and the Inherent Politics of Dance, chaired by Jonathan Burrows and Dan Daw, with guest speakers Bojana Kunst and Joe Moran. It is now published as part of A World of Muscle, Bone & Organs: Research and Scholarship in Dance, edited by Simon Ellis, Hetty Blades and Charlotte Waelde, published by CDaRE, 2018. The talk was also shared again as part of a seminar at the New Theatre Institute of Latvia on February 15th 2020.The aim of the research behind this talk was to begin the process of an examination into the often spoken relationship between dance practice and the political. The research and outcome of this talk covered two main elements of the relationship between dance and the political: the tendency of dance performers to describe their experience of dancing as being a form of freedom; and the tendency of practitioners to also assume a separation between their activities and the possibility of co-option or appropriation by economic or political forces. The talk echoed a research by Jonathan Burrows, Simon Ellis and Efrosini Protopapa, which began by trying to identify contradictory arguments for the value of dance, focussing on the question 'If the value of dance is that it has no value, what might this mean in a historical moment that calls for action?'. These questions sit centrally to current developments in the field, led by a younger generation many of whom are already invested as activists in parallel to their artistic work. It identifies crucial ways in which diverse dance artists might continue to build strength together to question current notions of cultural, political and economic value in dance, and support positive commonal resistance within each other's practice.CONTEXTUAL INFORMATION- Credits:text by Jonathan Burrowscommissioned by Inventur#2–Contemporary Dance and Performance Conference at Tanzhaus NRW Düsseldorf- First presentation:Inventur#2–Contemporary Dance and Performance Conference at Tanzhaus NRW Düsseldorf, June 2nd 2017- Also presented at:New Theatre Institute of Latvia, February 15th 2020- Published as part of : A World of Muscle, Bone & Organs: Research and Scholarship in Dance, edited by Simon Ellis, Hetty Blades and Charlotte Waelde, published by CDaRE, 2018</p

Male fiddler crabs defend multiple burrows to attract additional females
No full textMales of many species defend resources to attract females. Surprisingly, defense of multiple female breeding sites (e.g., nests or burrows) appears to be rare, primarily reported in fish and birds. In fiddler crabs, burrows are a vital resource for reproduction and survival. Both sexes defend individual territories centered on a single burrow. We examined burrow acquisition and defense in Uca capricornis to test whether males defend multiple burrows as a novel strategy to acquire additional mates. When crabs were experimentally forced to acquire a new burrow, females often settled into an empty burrow near resident males. We documented more empty burrows around males than expected by chance and, in addition, larger males had a greater proportion of empty burrows in their immediate vicinity. We experimentally introduced crabs into empty burrows next to focal males: newly introduced males were soon evicted, whereas females were courted and stayed. These results suggest that male U. capricornis defend empty burrows as a strategy to obtain more mates. Intriguingly, however, U. capricornis tend to occur in socially monogamous pairs. This raises the possibility of sexual conflict within social pairs over the presence of additional females and that female--female competition might constrain male mating success.

Lyndon Array construction during Burrows-Wheeler inversion
No full textIn this paper we present an algorithm to compute the Lyndon array of a string T of length n as a byproduct of the inversion of the Burrows-Wheeler transform of T. Our algorithm runs in linear time using only a stack in addition to the data structures used for Burrows-Wheeler inversion. We compare our algorithm with two other linear-time algorithms for Lyndon array construction and show that computing the Burrows-Wheeler transform and then constructing the Lyndon array is competitive compared to the known approaches. We also propose a new balanced parenthesis representation for the Lyndon array that uses bits of space and supports constant time access. This representation can be built in linear time using words of space, or in time using asymptotically the same space as T

<i>Planolites</i> isp. burrows from Mud Buttes.
No full text<p>(A) Plan view showing undersides of closely packed horizontal burrows at coal/silty sandstone interface. Note coal still adherent to some burrows (specimen KT3/UCM 98212). (B) Discernible burrows colored and numbered to illustrate minimum burrow density within 8 cm<sup>2</sup> (specimen KT4/UCM 98213). Portions of at least 23 burrows comprise roughly 30% of area of white box. Burrows are colored different shades of green to illustrate overlapping relationships. The burrowing activity likely took place within a short period of time, but burrows colored darker green were lower in the soil profile and appear to have been crossed <i>in situ</i> by other burrows (lighter shades of green). Burrows colored lightest green were the topmost burrows. Note that this specimen is the same as that in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0070920#pone-0070920-g001" target="_blank">Figure 1D</a>.
