Enhanced 2D Spiral Cine DENSE MRI Using Low‐Rank Denoising for Improved Apparent Signal‐to‐Noise Ratio, Spatial Resolution, Efficiency, Accuracy, and Accessibility

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a denoising technique for displacement encoding with stimulated echoes (DENSE) MRI that improves spatial resolution, efficiency, and accuracy, and enhances accessibility by implementing DENSE MRI at 0.55 T. Methods We developed a low‐rank denoising technique, which leverages multidimensional spiral cine DENSE MRI data for ...

Deep‐Learning‐Based Image Reconstruction to Improve End‐Diastolic and Systolic Cardiac T1 Mapping

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop an image reconstruction method that enables increased spatial resolution cardiac T1 mapping in both the end‐diastolic and systolic phase, that shows high T1 agreement with the clinical standard. The resolution gain is achieved by increasing the acceleration rate of MOLLI single‐shot images to R = 4, while maintaining a ...

Numerical Insights Into the Resistance Reduction Mechanisms of Forward Tapered Transoms in High‐Speed Catamaran: A Computational Fluid Dynamics‐Based Study

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study investigates the hydrodynamic influence of forward transom tapering on a displacement catamaran hull using computational fluid dynamics (CFD) simulations. Five taper configurations ranging from a vertical transom base design to a fully tapered stern (1.00B) were evaluated over a wide Froude number range (Fr = .3 to 1.0).

Subconjuctival Loa loa with Calabar Swelling

Journal of Korean Medical Science, 2008
Loa loa is unique among the human filariae in that adult worms are occasionally visible during subconjunctival migration. A 29-yr-old African female student, living in Korea for the past 5 yr without ever visiting her home country, presented with acute eyelid swelling and a sensation of motion on the left eyeball.

Impact of repeated mass ivermectin administration using a community directed approach on L. loa infection in Chrysops silacea of the rain forest and forest savanna of Cameroon

Parasite Epidemiology and Control
Background: Loiasis is an endemic filarial infection in the rainforest zone of West and Central Africa. Repeated annual community-directed treatment with ivermectin (CDTI) delivered for several years to control onchocerciasis has been shown to reduce the

Assessment of shear reinforcement enhancement on the punching shear capacity of flat concrete slabs with openings

Structural Concrete, EarlyView.
Abstract Reinforced concrete flat slabs are widely employed in contemporary architecture due to their structural efficiency and construction simplicity; however, their susceptibility to punching shear failure remains a critical design concern, particularly at slab–column connections where concentrated loads occur.

Nonlinear analysis of flat post‐tensioned concrete slab–edge column connections

Structural Concrete, EarlyView.
Abstract This study presents nonlinear finite element analyses to investigate the punching shear behavior of unbonded post‐tensioned concrete flat slabs at slab‐edge column connections. A parametric analysis was conducted to evaluate the influence of four critical parameters on the punching shear resistance: the distribution of prestressing tendons ...

Infeção por Loa loa

Revista Portuguesa de Doenças Infecciosas (RPDI), 2015
O nemátodo Loa loa, presente em África, é uma causa rara de eosinofilia nos países desenvolvidos, mas de importância crescente devido ao mundo globalizado em que vivemos. Os autores descrevem o caso de um doente do sexo masculino, 57 anos, sem medicação habitual, que é referenciado à consulta de Infeciologia por eosinofilia persistente.
