Introduction: Adult-onset growth hormone deficiency (AGHD) is usually the last deficiency to be substituted in hypopituitarism. In children with documented GH deficiency, treatment without delay is crucial for achieving optimal effects on growth and development. In adults, it is not known whether a delay in treatment initiation influences biochemical response and the favourable physiological effec
In 1953 Eva Hansen-Melander was appointed as a scientific assistant at the newly founded Cancer chromosome laboratory at Lund University, Sweden. The lab was set up by the cytologist Albert Levan, who started his career as a botanist studying Allium chromosomes but in the early 1950s changed his research focus to the studies of chromosomes in cancer cells. Levan developed close collaborations with
von Neumann's inequality in matrix theory refers to the fact that the Frobenius scalar product of two matrices is less than or equal to the scalar product of the respective singular values. Moreover, equality can only happen if the two matrices share a joint set of singular vectors, and this latter part is hard to find in the literature. We extend these facts to the separable Hilbert space setting
We describe how the optimal dual controller for a discrete-time linear system can be found by approximately solving the corresponding Bellman equation using a neural network to represent the value function. We illustrate the method on an example with time-varying dynamics, where the new method is shown to give improved performance.
The normal approach to digital control is to sample periodically in time. Using an analog of integration theory we can call this Riemann sampling. Lebesgue sampling or event based sampling, is an alternative to Riemann sampling. It means that signals are sampled only when measurements pass certain limits. In this paper it is shown that Lebesgue sampling gives better performance for some simple sys
Aims: The overall aim of this thesis was to study dietary components with focus on exposure and ability to affect gutpermeability, peripheral immune response and gut microbiota in children at genetic risk of developing CD. Thespecific aims were to study presence of food components that might induce intestinal inflammation, evaluatepossible effects on intestinal permeability by food emulsifiers, in
DEBATT. Svensk industri tar flera lovande initiativ, men omställningen går alldeles för långsamt – och i vissa branscher märks den knappt alls, skriver sju miljöforskare.
With development displacing more people and planned relocation being espoused as an adaptation strategy in response to climate change, research that explores the experiences of those who have been resettled is needed. The Maldives has a history of resettlement based on an ongoing policy of consolidation of dispersed populations to ensure access to services. The paper explores the history, politics
Emergency food aid is the dominant humanitarian response to food insecurity precipitated by disasters. There is a significant literature on food aid effectiveness (e.g., bolstering food security, targeting, modality selection) in various disaster contexts. Additionally, there are some studies on the potential disincentive effects on agricultural production among other unintended consequences. Howe
The exposure of vulnerable food systems to hazards often leads to outcomes such as food insecurity. In order to prevent such food insecurity, it is critical to understand the causal factors – or root causes – of vulnerability, particularly in a world of increasing risk. As such, this paper develops and implements a food system causal disaster vulnerability framework within the Bedamuni tribe of Pa
Climate change researchers argue that a residual domain exists beyond the limits of adaptation to prevent deleterious climate change impacts: this has been labeled as “loss and damage.” Over the last 8 years, there has been significant growth in loss and damage scholarship thus making it imperative to take stock of what we know already and directions for future research. We undertook a quantitativ
The societal costs of disasters around the world are continuing to increase and Pacific Island countries are considered some of the most vulnerable. This is primarily due to a combination of high hazard exposure coupled with a range of social, economic, physical, and political vulnerabilities. This article contributes to the growing body of work that aims to understand the causal factors of disast
