Effects of Twisting and Surface Finish on the Mechanical Properties of Natural Gut Harp Strings

Natural gut harp strings are made from twisted bundles of gut strips, which are dried, ground, and varnished. The effects of varying the twist angle and surface finishing on the mechanical properties of gut harp strings have been explored. Strings were tested over a range of twist angles from 23.5∘ to 58.3∘, and with all four combinations of ground or unground and varnished or unvarnished surface finishing. The principal effects of varying the degree of twisting were that the breaking strength and tensile Young’s modulus both fell as the twist angle was increased. String makers must therefore make a compromise between sound quality and string strength and durability. Leaving the string unvarnished dramatically increased the sensitivity to changes in humidity, which, in turn, affected the thermal tuning sensitivity and creep behaviour. Grinding the string surface prior to varnishing had no significant effect on the behaviour, but did make some difference to the thermal tuning sensitivity if the string was left unvarnished. Increasing the humidity frequently triggered episodes of additional string creep. There appeared to be a threshold effect, with the additional creep triggered when the string linear density exceeded its previous maximum. When the string was not creeping, there appeared to be a strong coupling mechanism between changes in the linear density and complementary changes in the string tension, such that there was almost no net effect on the string frequency. This behaviour was independent of the twist angle and the surface finishing, suggesting that whatever the coupling mechanism was, it was not dependent on the twisted structure of the string.
A NOVEL OPEN-SOURCE CARDIAC SEGMENTATION FRAMEWORK FOR CINE MRI

Cardiac contour delineation currently presents several proposals for automatic segmentation in short-axis MRI. However, most of them have drawbacks such as low accuracy with images from other MRI scanners, lack of description of the algorithms, and difficult access for clinical or research use. For this reason, we present VENTSEG, a deep learning framework for cardiac segmentation implemented in Matlab and Python. Our dice coefficient results segmenting images from the CNN validation set are 85.55% and 96.17% on anonymized clinical data. These results demonstrate the generalization of the framework on multidomain images.
Protocol harmonization using a generative adversarial network decreases morphometry variability

In radiology, the deployment of automated clinical decision support tools to new institutions is often hindered by inter-site data variability. In MRI, data heterogeneity often arises from differences in acquisition protocols. To overcome this issue, we propose a post-hoc harmonization technique based on generative adversarial networks (GAN). Seventy-seven patients suffering from dementia were scanned with two distinct T 1 -weighted MP-RAGE protocols. We show that cross-protocol harmonization of brain images using a conditional GAN improves image similarity and reduces the variability of brain morphometry.

Deictic Strategies in KamaNu and Karimi’s Kimeru Song and Dance Lyrics

Purpose: This paper examined the deictic strategies in the Kimeru song and dance lyrics by KamaNu and Karimi by assessing how the deictic properties of these song and dance lyrics express the main issues. The study utilized the aspects of Van Dijk’s (2008) ideological square as a component of his socio-cognitive approach to critical discourse analysis (CDA).&#x0D; Methodology: The study adopted a qualitative approach using descriptive research design in particular a case study. Research was carried out in Meru and Nairobi counties in Kenya. The target population consisted of native Meru artists and their fans. Two native Meru artists, a male and a female, namely: KamaNu and Karimi were purposively sampled as a corporate item. Twelve songs six from each of the artists were picked on popularity basis and that they had a traditional tinge and contained deictic content that were relevant to the study. Data was collected through six video recordings, semi-structured interviews and note taking of the actual live performances in social functions; three for each artist to enable the researcher get verbatim data and songs without any alterations, as well as save time.&#x0D; Findings: The study established that Kimeru song and dance lyrics by KamaNu and Karimi, through polarization of Us and Them, employ a cocktail of both simple and complex strategies to cater for people of all ages for purposes of understanding the intended meaning, while saving one’s face and as such smoothly transmits the societal ideals.&#x0D; Unique contribution to theory, policy and practice: The study recommends that listeners pay more attention to these diectic strategies for an appropriate interpretation of the intended meaning as they enable the speaker identify with the situation making listeners incline towards the music since it elevates the speaker on a pedestal of the informer and all knowing (Atoh, 2017). Secondly, the audience should discern the meaning of these expressions in accordance to the context under which they are used. There is therefore need for the policy makers to incorporate song and dance lyrics in the school curriculum as a technique of language teaching as well as preserve our cultural heritage through documentation for posterity
