We study non-invertible piecewise hyperbolic maps in the plane. The Hausdorff dimension of the attractor is estimated from below for a set of maps that is open in the C2 topology.

This article analyses the application of the 1972 United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Convention (the WHC) in the context of the armed conflicts that have taken place in the Virunga National Park (the Park), a natural world heritage site in the Democratic Republic of the Congo (the DRC). Instead of addressing wartime environmental damage under t

Hepatitis D virus (HDV) is dependent on the presence of hepatitis B virus (HBV) for transmission and replication because of its inability to produce its own coat. It remains unclear whether HDV infection increases the risk of hepatocellular carcinoma. Using the Swedish Hospital Discharge Register and Outpatient Registry, we identified 9160 patients with chronic HBV infection between 1997 and 2008,

To study the differential expression of cell membrane-bound receptors and their potential role in growth and/or survival of the tumor cells, highly purified follicular lymphoma cells were analyzed, using gene expression analysis, and compared to non-malignant B cell populations. Filtering the genome for overexpressed genes coding for cell membrane-bound proteins/receptors resulted in a hit list of

This article reviews endovascular strategies for aortic arch repair. Open repair remains the gold standard particularly for good risk patients. Endovascular treatment potentially offers a less invasive repair. Principles, technical considerations, devices and outcomes of each technique are discussed and summarized. Hybrid repair combines less invasive revascularization options, instead of arch rep

Objective: We used dual X-ray absorptiometry (DXA) to measure calcaneal bone mineral density (BMD) and estimate the prevalence of osteoporosis in a population with distal forearm fracture and a normative cohort. Methods: Patients 20 to 80 years of age with distal forearm fracture treated at one emergency hospital during two consecutive years were invited to calcaneal BMD measurement; 270 women (81

To study and compare associations between life satisfaction and standard of living, health, and coping behaviour in older single-living women in two countries with different political, economical and cultural situations: Latvia and Sweden. Cross sectional data included 260 Latvian and 288 Swedish women, aged 75-84 and 80-89, from the ENABLE-AGE Survey Study. Life satisfaction was assessed by the q

A scanned probe optical microscope allowing nondestructive studies of a wide range of objects and surfaces is described. The microscope utilizes a noninvasive optical trap to position a microscopic probe light source in immediate proximity to the studied object. We demonstrate the method experimentally and show theoretically its potential for optical imaging with subdiffraction limited resolution

Objectives. SLE is a systemic autoimmune disease with an annual incidence of 3.8 per 100 000. Several pathogenic mechanisms are believed to be operating in SLE, including an impaired clearance of apoptotic cells, activation of the type I IFN pathway and generation of autoimmune leucocytes. Growth arrest-specific protein 6 (Gas6) and its receptor Axl are known to regulate inflammation and may be im

We describe realizations of the color analogue of the Heisenberg Lie algebra by power series in non-commuting indeterminates satisfying Heisenberg's canonical commutation relations of quantum mechanics. The obtained formulas are used to construct new operator representations of the color analogue of the Heisenberg Lie algebra. These representations are shown to be closely connected with some combi

Popular Abstract in Swedish Denna avhandling diskuterar hur en föreställning om enhet har präglat västerländskt politiskt tänkande om politisk gemenskap. Den visar att ett antagande om likhet, återspeglad i tid, rum, språk och rationalitet, har setts som en förutsättning för politisk gemenskap. Antagandet om likhet innebär att varje försök att utvidga gemenskapen ger upphov till nya exkluderingar This thesis argues that the Western thinking of political community has assumed the community to require a unity or unifying principle that serves as delineation. It suggests that sameness, reflected in history, space, language, or reason, has been assumed as the condition of possibility of the political community. Consequently, a particular identity is made a prerequisite for membership and vouch

Context: Dipeptidyl peptidase-4 (DPP-4) inhibitors act by increasing plasma levels of glucagon-like peptide-1 (GLP-1) and suppressing excessive glucagon secretion in patients with type 2 diabetes (T2DM). However, their effects on the glucagon response to hypoglycemia are not established. Objective: Assess effects of the DPP-4 inhibitor vildagliptin on alpha-cell response to hyper- and hypoglycemia

Functioning of the immune system requires the coordinated expression and action of many genes and proteins. With the emergence of high-throughput technologies, a great amount of molecular data is available for the genes and proteins of the immune system. However, these data are scattered into several databases and literature and therefore integration is needed.
