Abstract

Tech conglomerates have launched many extension brands to enter the streaming media market. This paper analyses a study which examined the factors that affect these brand extensions from the perspectives of consumer attitude and perceptions. A total of 1,404 participants who reported having used parent brands were recruited for the study and were included in the final sample. Five hypotheses were tested using structural equation modelling analysis. Loyalty to the parent brand, variance in brand portfolio quality and perceived fit significantly influenced attitudes towards brand extensions. In addition, perceived fit and attitudes towards brand extensions positively reinforced consumer attitudes towards the parent brand. Finally, no difference was found with reference to the aforementioned factors when the more established streaming extensions were compared with the newer extensions of tech conglomerates. A unique aspect of the study is the structural validation of brand extensions by tech conglomerates. Further, the results of the study support the understanding of the importance of feedback effects and perceived fit in the brand area of tech conglomerates. [ABSTRACT FROM AUTHOR]

30. A comparison study of prabotulinumtoxinA vs onabotulinumtoxinA in myostatin‐deficient mice with muscle hypertrophy.

Abstract

Botulinum toxin A (BoNT‐A) is used clinically for various muscle disorders and acts by preventing the release of the neurotransmitter acetylcholine into the synapse space. Here, we compared the efficacy of prabotulinumtoxinA (PRA) and onabotulinumtoxinA (ONA) for the reduction in hypertrophy in myostatin‐deficient (Mstn−/−) mice. Two different BoNT‐A products (2.5, 10 and 25 U/kg) were injected to paralyse the hindlimb for 2 months, after which sciatic nerve conduction study, 3D micro‐CT, haematoxylin and eosin (H&E) and dystrophin staining were conducted. Administration of BoNT‐A products induced denervation‐mediated atrophy and alleviated muscle hypertrophy generated in Mstn−/− mice. The present study revealed that each BoNT‐A regulates skeletal muscle size, myofibre number and myofibre diameter in Mstn−/− mice. The potential applicability of BoNT‐A for the treatment of rare muscle hypertrophic diseases was demonstrated. Compared with ONA, PRA had a comparable ability to act in the local area.

Abstract

This paper describes an algorithm for minimal turning complete coverage Path planning for cleaning robots. This algorithm divides the whole cleaning area by cellular decomposition, and then provides the path planning among the cells employing a flow network. It also provides specific path planning inside each cell guaranteeing the minimal turning of the robots. The minimal turning of the robots is directly related to the faster motion and energy saving. The proposed algorithm is compared with previous approaches in simulation and the result shows the validity of the algorithm.
