Various types of graph statistics for graphs and digraphs are presented as numerators of incomplete U-statistics, with symmetric and asymmetric kernels, respectively. Thus, asymptotic Poisson limits of these statistics are provided by using limit theorems for the sums of dissociated random variables. Several applications to statistical analysis of graphs are given
The conversion of sodium lactate to lactic acid with water-splitting electrodialysis was investigated. One way of reducing the power consumption is to add a conductive layer to the acid compartment. Doing this reduced the power consumption by almost 50% in a two-compartment cell, whereas the electric current efficiency was not affected at all. Three different solutions were treated in the electrod
There is in large parts of the world a demographic crisis. Due to the increase in life length and the drop inbirth rates, prospects are that much fewer people of working age will be available in the future to supportthose in retirement.Also Sweden faces a demographic challenge, implying that it will be necessary to make the Swedeswork more years. There is an obvious potential in the age range 65-7
The topic of the thesis is re-initialization of multistep methods for the solution of ordinary differential equations, in which there are frequent discontinuities in first or higher derivatives. There are self-starting algorithms to start or restart a multistep method. It is normally started by first using a one-step method and then increasing the order successively until the working order is reac
Introduction: Carpal tunnel syndrome (CTS) is a common condition especially for people with diabetes, obesity or women who are pregnant. Diagnosing CTS has primarily been performed using electroneuronography. In this thesis the aim was to use an advanced method of tractography to measure and evaluate diffusion tensor imaging (DTI) parameters between anatomical landmarks at the distal radioulnar jo
The aetiology of oral lichen lesions is obscure. In this study the frequency of contact allergy to gold in 83 patients with oral lichen lesions was compared with that in two control groups, comprising 319 age- and gender-matched patients with dermatitis selected from files and 83 clinically examined dermatitis patients. All patients were tested epicutaneously with gold sodium thiosulphate. The two
The interactions of biological macromolecules with nanoparticles underlie a wide variety of current and future applications in the fields of biotechnology, medicine and bioremediation. The same interactions are also responsible for mediating potential biohazards of nanomaterials. Some applications require that proteins adsorb to the nanomaterial and that the protein resists or undergoes structural
The study examines one of the core elements of the European Green Deal - the Farm to Fork Strategy. It has a goal to translate the intentions and proposals of the Strategy into the business language and evaluate potential impacts for the agri-business and other value chain players like IKEA. Using the legal doctrine method, the study analyses the documents on the Strategy’s actions, adding experts
Osteoarthritis (OA) is a heterogeneous inflammatory joint disease that affects around 240-250 million people worldwide. The disease is a prominent cause of disability and a leading source of societal expenses in older adults. As of today, personalized OA treatment is considered essential and is currently being addressed in several osteoarthritis guidelines. To explore the possibilities of precisio
Using structural properties of groups of small order, we establish the non-existence of varieties isogenous to a higher product of dimension n greater than 3 with fixed topological Euler number (-2)n and trivial first Betti number.
Although biomedical information is growing rapidly, it is difficult to find and retrieve validated data especially for rare hereditary diseases. There is an increased need for services capable of integrating and validating information as well as proving it in a logically organized structure. A XML-based language enables creation of open source databases for storage, maintenance and delivery for di
This paper gives a global solution to an H-infinity control problem for systems with symmetric state matrix and state-dependent input matrix. A simple, closed-form expression for the minimizing controller is obtained. This is in contrast to already established theory in which nonlinear H-infinity problems are solved locally. The result is then illustrated through an example, and the potential for
An adaptive controller is proposed and analyzed for the class of infinite-horizon optimal control problems in positive linear systems presented in (Ohlin et al., 2024b). This controller is derived from the solution of a “data-driven algebraic equation” constructed using the model-free Bellman equation from Q-learning. The equation is driven by data correlation matrices that do not scale with the n
During host colonization, bacteria use the alarmones (p)ppGpp to reshape their proteome by acting pleiotropically on DNA, RNA, and protein synthesis. Here, we elucidate how the initiating ribosome senses the cellular pool of guanosine nucleotides and regulates the progression towards protein synthesis. Our results show that the affinity of guanosine triphosphate (GTP) and the inhibitory concentrat
Despite their emancipatory aspirations, collective entrepreneurial efforts to change organizations bottom-up are often complicit with the power structures they seek to transform. Our study takes a closer look at how workers experience and deal with the tensions between emancipation and complicity and how this can inform the entrepreneurial process. Empirically, we draw from a qualitative single-ca
With conventional antibiotic therapies being increasingly ineffective, bacterial infections with subsequent biofilm formation represent a global threat to human health. Here, an active and a passive strategy based on polymeric micelles were combined to fight bacterial growth. The passive strategy involved covalent immobilization of polymeric micelles through Michael addition between exposed maleim
