Base-Anchored Model for Highly Scalable and Accessible Compression of Multiview Imagery.

We present a compression scheme for multiview imagery that facilitates high scalability and accessibility of the compressed content. Our scheme relies upon constructing at a single base view, a disparity model for a group of views, and then utilizing this base-anchored model to infer disparity at all views belonging to the group. We employ a hierarchical disparity-compensated inter-view transform where the corresponding analysis and synthesis filters are applied along the geometric flows defined by the base-anchored disparity model.

Modifiable lifestyle factors in dementia: a systematic review of longitudinal observational cohort studies.

Background: Numerous population-based longitudinal studies suggest an association between modifiable lifestyle factors and late-life dementia. A comprehensive description of these factors and their quantification criteria is an important preliminary step toward the elucidation of causes and mechanisms underlying the onset and progression of dementia.

Objective: To present a systematic review of modifiable lifestyle factors associated with dementia risk in longitudinal observational cohort-studies.

Method of aneurysm treatment does not affect clot clearance after aneurysmal subarachnoid hemorrhage.

Background: Patients undergoing neurosurgical clipping or endovascular coiling of a ruptured aneurysm may differ in their risk of vasospasm.

Objective: Because clot clearance affects vasospasm, we tested the hypothesis that clot clearance differs in patients depending on method of aneurysm treatment.

Methods: Exploratory analysis was performed on 413 patients from CONSCIOUS-1, a prospective randomized trial of clazosentan for the prevention of angiographic vasospasm in patients with aneurysmal subarachnoid hemorrhage (SAH).

Angiographic vasospasm is strongly correlated with cerebral infarction after subarachnoid hemorrhage.

Background And Purpose: The long-standing concept that delayed cerebral infarction after aneurysmal subarachnoid hemorrhage results exclusively from large artery vasospasm recently has been challenged. We used data from the CONSCIOUS-1 trial to determine the relationship between angiographic vasospasm and cerebral infarction after subarachnoid hemorrhage.

Methods: We performed a post hoc exploratory analysis of the CONSCIOUS-1 data.

Endovascular treatment or neurosurgical clipping of ruptured intracranial aneurysms: effect on angiographic vasospasm, delayed ischemic neurological deficit, cerebral infarction, and clinical outcome.

Background And Purpose: The effects of aneurysm treatment modality (clipping or coiling) on the incidence of cerebral vasospasm and infarction after subarachnoid hemorrhage have not been clearly defined. We hypothesized that there may be a difference in angiographic and clinical vasospasm, cerebral infarction, and clinical outcome between patients undergoing clipping compared to coiling.

Methods: A retrospective, exploratory analysis of 413 patients randomized into the CONSCIOUS-1 trial was conducted.
