The problem of adaptive control is considered from a perspective of l2-gain. It has recently been shown that without an a priori bound on the system parameters, there exists no single dynamic feedback law that achieves bounded gain from disturbances to state for all first order linear systems. In this paper, a converse statement is proved for a standard adaptive scheme where the parameter estimate
Manufacturing processes can generally be classified as continuous, discrete or batch. An industrially well accepted way of structuring and controlling batch processes is presented in the ISA 88 standard (also known as IEC 61512). In exploring how this standard also could be used for discrete manufacturing processes, especially in robotic applications, different challenges and opportunities are fou

We explore how team gender composition affects willingness to lead by randomly assigning participants in an experiment to male- or female-majority teams. Irrespective of team gender composition, men are substantially more willing than women to lead their team. The pooled sample, and women separately, are more willing to lead female- than male-majority teams. An analysis of mechanisms reveals that
Encounters between patients in homecare and nursing students are cultural events where students, in principle, are in unknown territory. This study illuminated how nursing students recount (inter)actions in social relations in Danish homecare settings, illustrated by students with a self-appointed immigrant background. The study consisted of semi-structured interviews with eight nursing students.
Background: Allergic contact dermatitis can negatively impact an individual's daily life in terms of work and interpersonal relationships. Patch-tested individuals show an improved quality of life (QoL). Objectives: We aimed to assess the impact on QoL after patch testing and what value an intervention would have on QoL. Methods: Dermatology Quality of Life Index (DLQI) were assessed in participan
Krüppel-like factors (KLFs) are transcription factors with important roles in tissue homeostasis. KLF4 possesses antithrombotic and anti-inflammatory properties. In this issue, Estrada et al. show that endothelial KLF4 prevents complement deposition in glomeruli and in its absence the cell-bound complement regulator CD55 was reduced. The study included endothelial-specific KLF4 knockdown mice that
Barrow’s timely book is the first to examine the link between Victorian poetry, the study of language, and political reform. Focusing on a range of literary, scientific, and political texts, Barrow demonstrates that nineteenth-century debates about language played a key role in shaping emergent ideas about popular sovereignty. While Victorian scientists studied the origins of speech, the history o
South Africa’s energy sector finds itself in a gridlock situation. The sector is controlled by the state-owned utility Eskom holding the monopoly on the generation and transmission of electricity, which is almost exclusively produced from domestically extracted coal. At the same time, the constitutional mandate enables municipalities to distribute and sell electricity generated by Eskom to local c
Muhammad 'Abduh (1849-1905) was one of the key thinkers and reformers of modern Islam who has influenced both liberal and fundamentalist Muslims today. 'Abdul-Baha (1844-1921) was the son of Baha'ullah (1817-1892), the founder of the Baha'i Faith; a new religion which began as a messianic movement in Shii Islam, before it departed from Islam. Oliver Scharbrodt offers an innovative and radically ne
China is using Buddhist narratives to promote its soft power in Sri Lanka – and bolster its image as a harmonious regional power.
