Lift Enhancement for Low-Aspect-Ratio Wings with Periodic Excitation [PDF]
, 2010 In an effort to enhance lift on low-aspect-ratio rectangular flat-plate wings in low-Reynolds-number post-stall flows, periodic injection of momentum is considered along the trailing edge in this numerical study.

Role of surface microgeometries on electron escape probability and secondary electron yield of metal surfaces [PDF]
, 2020 The influence of microgeometries on the Secondary Electron Yield (SEY) of surfaces is investigated. Laser written structures of different aspect ratio (height to width) on a copper surface tuned the SEY of the surface and reduced its value to less than ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Pulmonary dysfunction and sleep abnormalities are common in children with sickle cell disease (SCD) and are associated with worse clinical outcomes. Whether spirometry abnormalities are associated with polysomnography (PSG) findings remains unclear.

High-aspect-ratio nanoimprint process chains [PDF]
Microsystems & Nanoengineering, 2017 AbstractDifferent methods capable of developing complex structures and building elements with high-aspect-ratio nanostructures combined with microstructures, which are of interest in nanophotonics, are presented. As originals for subsequent replication steps, two families of masters were developed: (i) 3.2 μm deep, 180 nm wide trenches were fabricated ...

Theory of small aspect ratio waves in deep water
, 2005 In the limit of small values of the aspect ratio parameter (or wave steepness) which measures the amplitude of a surface wave in units of its wave-length, a model equation is derived from the Euler system in infinite depth (deep water) without potential ...

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Determining the Aspect Ratio of a wing based on its Mean Aerodynamic Chord [PDF]
CientíficaThe aspect ratio of a wing has its origin in the concept of slenderness, understood as the visual aspect that results from comparing its length with its width, that is, its span between its chord, but considering a rectangular shape, it which, in turn ...
