Restoration of function after stroke may be associated with structural remodeling of neuronal connections outside the infarcted area. However, the spatiotemporal profile of poststroke alterations in neuroanatomical connectivity in relation to functional recovery is still largely unknown. We performed in vivo magnetic resonance imaging (MRI)-based neuronal tract tracing with manganese in combina...

Hydrological connectivity is an essential indicator of wetland pattern and functional stability. The reduction usually means the degradation ecological function, internal energy flow, nutrient cycle disturbance. Taking Hanshiqiao as a case, we used Morphological Spatial Pattern Analysis (MSPA) with Connectivity Index (IIC, Integral Connectivity; PC, Probability Connectivity) to analyze change i...

Estimating genetic connectivity in disturbed riverine landscapes is of key importance for river restoration. However, few species of the disturbed riverine fauna may provide a detailed and basin-wide picture of the human impact on the population genetics of riverine organisms. Here we used the most abundant native fish, the three-spined stickleback (Gasterosteus aculeatus L.), to detect the geo...

Francesco de Pasquale Dynamic Magnetic Resonance Imaging is a non-invasive technique that provides an image sequence based on dynamic information for locating lesions and investigating their structures. In this thesis we develop new methodology for analysing dynamic Magnetic Resonance image sequences of the breast. This methodology comprises an image restoration step that reduces random distort...

Cervical dystonia is characterized by involuntary, abnormal movements and postures of the head and neck. Current views on its pathophysiology, such as faulty sensorimotor integration and impaired motor planning, are largely based on studies of focal hand dystonia. Using resting state fMRI, we explored whether cervical dystonia patients have altered functional brain connectivity compared to heal...

Ischemic damage to the brain triggers substantial reorganization of spared areas and pathways, which is associated with limited, spontaneous restoration of function. A better understanding of this plastic remodeling is crucial to develop more effective strategies for stroke rehabilitation. In this review article, we discuss advances in the comprehension of post-stroke network reorganization in ...

The importance of connectivity is well established in traditional disciplinary environmental fields, namely hydrology and ecology. Although conventions for defining connectivity in those fields differ, structural connectivity typically refers to the degree of spatial connectedness of landscape features, whereas functional connectivity refers to the degree of permeability of landscapes for certa...

Shoreline armoring is prevalent around the world with unprecedented human population growth and urbanization along coastal habitats. Armoring structures, such as riprap and bulkheads, that are built to prevent beach erosion and protect coastal infrastructure from storms and flooding can cause deterioration of habitats for migratory fish species, disrupt aquatic-terrestrial connectivity, and red...

Coast redwood (Sequoia sempervirens (Lamb. ex. D. Don) Endl.) is unique among conifer species because of its longevity, the great sizes of individual trees, and its propensity to reproduce through sprouts. Timber harvesting in the native redwood range along the coast of the western United States has necessitated restoration aimed to promote old forest structures to increase the total amount of ...

In this paper we propose a new approach for optical layer restoration management in a dynamically reconfigurable optical network. The optical network consists of Optical Layer Cross-connects (OLXCs) which have the ability to convert the wavelength of any incoming channel to any outgoing wavelength (i.e. have wavelength conversion). Recently, there has been intense interest within the optical ne...
