This paper studies the Vlasov-Monge-Ampère system (VMA), a fully non-linear version of the Vlasov-Poisson system (V P ) where the (real) Monge-Ampère equation det ∂ Ψ ∂xi∂xj = ρ substitutes for the usual Poisson equation. This system can be derived as a geometric approximation of the Euler equations of incompressible fluid mechanics in the spirit of Arnold and Ebin. Global existence of weak sol...

OBJECTIVE To evaluate the anatomical and visual outcomes of patients treated with ocriplasmin for the treatment of symptomatic vitreomacular adhesion (sVMA), including vitreomacular traction syndrome and macular holes. DESIGN Retrospective, interventional, single centre, case series. PARTICIPANTS Patients with sVMA. INTERVENTION Patients were treated with a single intravitreal injection o...

BACKGROUND While low back pain is one of the most prevalent, if not the most prevalent reasons for visits to physicians, a majority of patients with low back pain cannot be given a definitive diagnosis. While there have been substantial advances in imaging technologies over the past 30 years, relatively little has changed in the methodologies for evaluating functionality of the lumbar spine. Th...

Pheochromocytoma is a tumor of adrenal medulla, derived from catecholamine producing chromaffin cells. Majority of the patients present with headache, palpitations and sweating. It is diagnosed by 24 hour urinary VMA (Vinyl Mendelic Acid) measurements and localization is done by MRI and 123I MIBG scanning. Treatment is essentially surgical with adequate preoperative blood pressure control. Undi...

Sufficient deformability can be achieved in concrete while maintaining segregation resistance either by using a chemical viscosity-modifying admixture (VMA) or increasing the fine content concrete. Using VMA, initial cost of self-compacting (SCC) increases, making it unsuitable for general construction. As result, alternative methods lowering SCC must investigated. In this study, we assess effe...

The paper presents a review of the sequence of events of posterior vitreous detachment (PVD), vitreomacular adhesion (VMA), vitreomacular traction (VMT), and macular hole (MH) from their pathophysiological aspects, clinical features, diagnostic implications, and current management strategies. A treatment algorithm to be used in clinical practice in patients with VMA, VMT, and MH based on the pr...

Engineered Cementitious Composites (ECC) have superior mechanical and durability performance than conventional concrete. One of the major challenges producing ECC is to ensure appropriate rheology for uniform fibre distribution, which prerequisite its strain-hardening robustness. In this study, combined interactive effects polycarboxylate-based superplasticisers (SP) viscosity modifying admixtu...

Mutants of Saccharomyces cerevisiae that lack vacuolar proton-translocating ATPase (V-ATPase) activity show a well-defined set of Vma- (stands for vacuolar membrane ATPase activity) phenotypes that include pH-conditional growth, increased calcium sensitivity, and the inability to grow on nonfermentable carbon sources. By screening based on these phenotypes and the inability of vma mutants to ac...
