This paper is concerned with model fitting in the presence of noise and outliers. Previously it has been shown that the number of outliers can be minimized with polynomial complexity in the number of measurements. This paper improves on these results in two ways. First, it is shown that for a large class of problems, the statistically more desirable truncated L-2-norm can be optimized with the sam
In this study, macroscopic and spectroscopic data were combined to develop a surface complexation model that describes the acid-base properties of Bacillus subtilis. The bacteria were freeze-dried and then resuspended in 0.1 M NaCl ionic medium. Macroscopic measurements included potentiometric acid-base titrations and electrophoretic mobility measurements. In addition, ATR-FTIR spectra of wet past
The short- and long-term effects of heavy-resistance training (85% of one-repetition maximum (RM)) on elbow flexion and knee extension dynamic and isokinetic strength and on morphology in the biceps brachii and vastus lateralis muscles were evaluated during 1 year in 35 Scandinavian men and women, aged 70-77 years, 12 of whom formed a control group. After the first 11 weeks of training (n = 23; 3
DNA aneuploidy, which reflects changes in nuclear DNA-content, as determined cytometrically is a candidate prognostic factor in squamous cell carcinoma of the head and neck. The aim of this study was to compare two different preparation methods with respect to their use in detecting aneuploid tumor cell populations in malignant tumors of the head and neck. Fresh frozen tumor material was used. The
Popular Abstract in Swedish De semi-arida regionerna i norra Kina är drabbade av många faktorer som påverkar miljön negativt, t.ex. ökenspridning, vind erosion, överbetning, uttömmande av naturresurser. Det redan hårda trycket på ekosystemen i dessa regioner har ökat sedan Kina införde marknadsekonomi. Reformerna sedan 1978 har lett till en snabb ökning av antalet betesdjur och en expansion av jorLand degradation is commonly perceived to be severe in many parts of semi arid China. The transition towards market economy since the 1978 reforms, have set marginal dry lands under added pressure in the form of increased livestock numbers and expanding cultivation on erosive soils. To evaluate land degradation since the reforms, this study focuses on mapping and analysing the biological productio
We studied the prevalence and intensity of the haemosporidian blood parasite Haemoproteus payevskyi in great reed warblers at Lake Kvismaren (6 years) and Lake Segersjo (3 years) in Sweden. Based on microscopic inspection of slides from 282 adult birds, 20.6% showed infection of H. payevskyi in circulating red blood cells in at least 1 year. For parasite prevalence, there was no difference between
colon; Prompted by previous studies suggesting that bulimia nervosa in women may be associated with elevated serum levels of testosterone, we have evaluated the possible effect of androgen antagonism in this condition. To this end, women meeting the DSM-IV criteria of bulimia nervosa, purging type, were treated in a one-center study with the androgen receptor antagonist flutamide (n = 9), the sero
An experimental and theoretical study of the effect of flow maldistribution from port to channel on the thermal performance of single and multipass plate heat exchangers is presented. In general, flow maldistribution brings about an increase in pressure drop and decrease of the thermal performance in heat exchangers. This deterioration is found to depend on flow rate, number of channels, and port
The increasing interest in the European historical log construction has heightened the need for comprehensive studies in different parts of the continent to view both the common features and the particular ones. The advanced Scandinavian research has revealed the problems of studying in depth and maintaining the log heritage when links to traditional carpentry are lost. One of the fortunate places
The mitochondrial oxidative phosphorylation system in plants possesses a variety of alternative pathways that decrease respiratory ATP production. These alternative pathways are mediated by three classes of bypass proteins: the type II NAD(P) H dehydrogenases (which circumvent complex I of the electron transport chain), the alternative oxidases (AOXs; which circumvent complexes III and IV) and the
The emergence of new media technologies, particularly the Internet, has transformed communicative environments and media landscape, influencing social, cultural and political processes in our everyday life. It is claimed to contribute to the recent transnational large-scale social movements in the last decade such as the anti-globalization protests like well-known ‘Battle of Seattle’ in 1999 or th
Tidigt under åren i arkitektskolan lär vi oss att forma och utforska våra egna kreativa processer. Dessa blir djupt personliga, och i detta projekt vill jag försöka formulera och utforska mitt sätt att arbeta. Under min studietid har jag upplevt att de största problemen jag haft under designprocessen varit att jag tenderat att bli för självkritisk i ett tidigt skede, vilket har resulterat i låsnin
Vegetation in the subarctic is expected to respond to climate warming as its growth becomes less temperature limited. This has previously been recorded in the form of treeline advances and increasing shrub cover. Changes in vegetation cover may accelerate warming due to a decrease in summer albedo, in what is termed surface albedo feedback. A quantification of the relationship between vegetation c
This thesis analyzes how the young public feels about communication efforts that seek to emotionally appeal to them, by investigating the example of brand activist campaigns. By applying narrative theory, the study examines how these campaigns are structured to evoke emotions and how the young public emotionally responds to them. This way, the thesis has a holistic approach to the emotional side o
This thesis examines the compatibility of the European Union’s countervailing duties on imports of Chinese battery electric vehicles with World Trade Organization law. Particular focus is given to the causation and non-attribution requirements under Article 15.5 of the Agreement on Subsidies and Countervailing Measures, in conjunction with the threat of material injury standard under Article 15.7.
Nesting phenology in birds has been studied for decades and two different breeding strategies have been identified, income and capital breeding. The nesting behaviour and the breeding strategies of 131 females were studied from three species, the Common eider (Somateria mollissima) (n = 65), known to be a capital breeder and two species the Velvet scoter (Melanitta fusca) (n = 48) and the Red-brea
This thesis examines the effects of pseudo and quasi-random number generators on the accuracy and efficiency of Monte Carlo Integration in the case of the multivariate normal distribution. The study compares the performance of the Mersenne Twister (a pseudo-random number generator) with Sobol and Halton sequences (quasi-random number generators). By evaluating these generators across different dim
Digital media and social media are by now established platforms for daily online social interaction, expression and debate, also in the political field. They offer users a space to voice and exchange opinions, as well as a tool to organise political acts of protest or support around offline world events. And they are changing the game of politics in remarkable ways. Political institutions such as
