Impairment and recovery of postural control in rabbits with spinal cord lesions.

The aim of this study was to characterize impairment and subsequent recovery of postural control after spinal cord injuries. Experiments were carried out on rabbits with three types of lesion--a dorsal (D), lateral (L), or ventral (V) hemisection (HS) at T(12) level. The animals were maintaining equilibrium on a platform periodically tilted in the frontal plane. We assessed the postural limb/trunk

A study of the neutral undistorted vacancy in silicon

Within the local energy independent pseudopotential theory, a convergent supercell calculation of the position of the discrete impurity level produced by the neutral undistorted vacancy in silicon has been performed. Translational symmetry was reintroduced by placing the impurities on a Bravais lattice. The author made calculations with unit cells containing up to 2662 atoms plus vacancy. A deep l

MODEL-BASED ITERATIVE RECONSTRUCTION ENABLES THE EVALUATION OF THIN-SLICE COMPUTED TOMOGRAPHY IMAGES WITHOUT DEGRADING IMAGE QUALITY OR INCREASING RADIATION DOSE.

Computed tomography (CT) is one of the most important modalities in a radiological department. This technique not only produces images that enable radiological reports with high diagnostic confidence, but it may also provide an elevated radiation dose to the patient. The radiation dose can be reduced by using advanced image reconstruction algorithms. This study was performed on a Brilliance iCT, e

Seed predators in south Swedish deciduous woods: a field experiment

Seeds from oak, horse chestnut, hawthorn, and sloe were exposed to seed predation during one week in autumn and over winter (for 6 months) in two different years. Three different exposure treatments were used and designed to exclude (1) small mammals and birds or (2) birds or (3) none. Insects and slugs had access to all exposures. 16 replicate experiments were set up in different deciduous woods

Homelands Lost and Gained : Slavic Migration and Settlement on Bornholm in the Early Middle Ages

This doctoral thesis examines early medieval Slavic migration to the island of Bornholm (Denmark). With a combination of interdisciplinary theories and approaches, which focus on human translocation and memory and identity construction, a holistic approach to the studies of migration in archaeology is proposed. It is argued that in order to address cases of migration it is necessary to consider th

Differential gene expression in adipose tissue from obese human subjects during weight loss and weight maintenance.

BACKGROUND: Differential gene expression in adipose tissue during diet-induced weight loss followed by a weight stability period is poorly characterized. Markers of these processes may provide a deeper understanding of underlying mechanisms. OBJECTIVE: We aimed to identify differentially expressed genes in human adipose tissue during weight loss and weight maintenance after weight loss. DESIGN:

A digitally controlled shunt capacitor CMOS delay line

Delay-controlled CMOS delay lines have been proved useful in a number of applications, notably the digitization of short time intervals. This paper introduces a new kind of CMOS delay line, in which the delay element is an array of capacitors controlled by a digital signal vector. This choice allows for a robust implementation of the circuitry controlling the delay generation, while the maximum sp
