Reconstruction of 3D-Curves from 2D-Images Using Affine Shape Methods for Curves

In this paper, we propose an algorithm for doing reconstruction of general 3D-curves from a number of 2D-images taken by uncalibrated cameras. No point correspondences between the images are assumed. The curve and the view points are uniquely reconstructed, modulo common projective transformations and the point correspondence problem is solved. Furthermore, the algorithm is independent of the choi

On Homogeneous Density Functions

We consider homogeneous density functions for proving almost globalattractivity of the zero equilibrium in a homogeneous system. It is shownthat the existence of such a function is guaranteed whenthe equilibrium is asymptotically stable, or in the more general case, whenthere exists a nonhomogeneous density function for the same systemsatisfying some reasonable conditions.

Clinical tests on impairment level related to low back pain: A study of test reliability

The objectives of the study were, in a working population, to standardize and evaluate a set of clinical tests on impairment level related to the low back with reference to intra- and inter-rater reliability. The study was undertaken in two steps. In step 1, 15 tests were examined for inter-rater reliability by three pairs of physiotherapists and for intra-rater reliability by one physiotherapist.

Identification of Csk tyrosine phosphorylation sites and a tyrosine residue important for kinase domain structure

The lack of a conserved tyrosine autophosphorylation site is a unique feature of the C-terminal Src-kinase, Csk, although this protein tyrosine kinase can be autophosphorylated on tyrosine residues in vitro and in bacteria. Here we show that human Csk is tyrosine phosphorylated in HeLa cells treated with sodium pervanadate. Phosphorylation in vivo occurs mainly at Tyr-184 and in vitro mainly at Ty

Standardization of antibody preparations for use in immunogenicity studies: a case study using the World Health Organization International Collaborative Study for Islet Cell Antibodies.

The immunogenicity of biological therapeutic products is currently a high profile regulatory and biotechnology industry issue. The immune responses raised against biotechnology products range from the benign, to affecting product efficacy, to those that have serious deleterious clinical impact. The most widely used marker of immunogenicity is the detection and measurement of antibody responses ind

Uncertain future of trials in osteoporosis

The advent of effective agents for the treatment of osteoporosis has led to the view that placebo-controlled trials to test new agents for efficacy are no longer appropriate since proven treatments are available. In this review we argue that, if new agents are to be developed, there is still a place for the placebo-controlled trial. A move to studies of equivalence or non-inferiority raises more p

Improved sensory relearning after nerve repair induced by selective temporary anaesthesia - a new concept in hand rehabilitation.

The outcome after nerve repair in adults is generally poor. We hypothesized that forearm deafferentation would enhance the sensory outcome by increasing the cortical hand representation. A prospective, randomized, double-blind study was designed to investigate the effects of cutaneous forearm anaesthesia combined with sensory re-education on the outcome after ulnar or median nerve repair. During a

Quadricuspid aortic valve not discovered by transthoracic echocardiography.

Background Quadricuspid aortic valve is a rare congenital heart defect. Several different anatomical variations of a quadricuspid aortic valve has been described and aortic regurgitation is the predominant valvular dysfunction associated with quadricuspid aortic valve. Case presentation A 68-year-old woman presented with almost a years history of increasing dyspnoea on exertion. The patient have

Inhibition of coxsackie B virus infection by soluble forms of its receptors: Binding affinities, altered particle formation, and competition with cellular receptors

We previously reported that soluble decay-accelerating factor (DAF) and coxsackievirus-adenovirus receptor (CAR) blocked coxsackievirus 133 (CVB3) myocarditis in mice, but only soluble CAR blocked CVB3-mediated pancreatitis. Here, we report that the in vitro mechanisms of viral inhibition by these soluble receptors also differ. Soluble DAF inhibited virus infection through the formation of reversi

Evaluation of an optical sensor for tuber yield monitoring

A sensor for monitoring the yield of tubers was tested in the laboratory and in the field. The laboratory test was designed to investigate whether the sensor varied in its measurements of tuber size, whether the recorded size differed within the width of the sensor, and whether tilting of the sensor affected the result. The test objects were spheres, and measurements were carried out on three diff

Family caregiving in dementia

The burden of caregivers of patients suffering from of Alzheimer type dementia (DAT) and vascular dementia (VD) was analysed at the critical time, the “breaking-point”, when home care becomes insufficient and/or inadequate and the caregiver burden has probably reached its upper limit. Primary family caregivers of 39 DAT and 40 VD patients who were being considered for relocation into group-living

Factors Associated with Development of Large Abdominal Aortic Aneurysm in Middle-aged Men.

Objectives. To investigate whether any variables in a health-screened population study were associated with later developnent of large abdominal aortic aneurysms (AAA). Setting. Malmo, Southern Sweden. Material and methods. Within the Malmo Preventive Study 22,444 men and 10,982 women were investigated between 1974 and 1991. The mean age at the health screening was 43.7 years. Results. After a med
