A hollow-core fiber using anisotropic anti-resonant tubes in the cladding is proposed for low loss and effectively single-mode guidance. We show that the loss performance and higher-order mode suppression is significantly improved by using symmetrically distributed anisotropic anti-resonant tubes in the cladding, elongated in the radial direction, when compared to using isotropic, i.e. circular...

• Capillary tubes & SAW devices used to pattern particles in no-flow flowing setups Rectangular tube: particle lines are parallel tube sidewalls for all directions Circular alignment depends on their position along the height Bottom/mid height: parallel/perpendicular direction Continues flow: always flow Acoustofluidic platforms have great potentials integrate capillary controlling and manipula...

In addition to improving population health, an important goal of health systems is to ensure that the financial burden of paying for health is distributed fairly across households (1). Exploring fairness in financial contribution requires the ability to measure each household’s financial contribution (HFC), defined as the ratio of a household’s health system contributions to its capacity to pay...

The performance of two evaporatively cooled heat exchangers is investigated under similar operating conditions of air flow rates and inlet hot water temperatures. The heat exchangers are plain and plate-finned circular tube types which occupy the same volume. Spray water, which is circulated in a closed circuit, is injected onto the exposed surfaces of the tubes and fins. The contact between ai...
