Advanced Science, EarlyView.This work demonstrates ultra‐high ON‐OFF responsivity of AJP by mechanical switching valve assisted shuttering. The jet relaxation and ON‐OFF delay are substantially eliminated from greater than 35 s, maintaining patterning quality independent of the variations of printing parameters, permitting excellent process stability and universality.

Effects of boundaries for high Reynolds number artificial swimmers
Scientific ReportsThe spatial organization of active particles or swimmers may depend strongly on the nature of the interaction between the particles and the boundary. Here we use robotic fish of several centimeters dimensions that swim at high enough velocities to reach ...

Effects of Low Reynolds Number on Wake-Generated Unsteady Flow of an Axial-Flow Turbine Rotor
International Journal of Rotating Machinery, 2005 The unsteady flow field downstream of axial-flow turbine rotors at low Reynolds numbers was investigated experimentally using hot-wire probes. Reynolds number, based on rotor exit velocity and rotor chord length Reout,RT, was varied from 3.2×104 to 12 ...

Computation of high Reynolds number internal/external flows [PDF]
A general, user oriented computer program, called VNAF2, developed to calculate high Reynolds number internal/external flows is described. The program solves the two dimensional, time dependent Navier-Stokes equations. Turbulence is modeled with either a

A Skills Gap Analysis of Farmer Directors of US Farmer Cooperatives
Agribusiness, EarlyView.ABSTRACT Boards of directors are vital to firm performance and are an integral part of the decision‐making process of any business. Several studies have been conducted that observe corporate or nonprofit board characteristics, skills, and the board's connection to firm performance.

The Power of Unity: Collective Action and Smallholder Agricultural Performance in West Africa
Agribusiness, EarlyView.ABSTRACT We analyze the impact of collective action through farmer‐based organizations (FBOs) on smallholders' farm performance and income inequality in Ghana, Benin, The Gambia, and Mali. We find that FBO membership increases cereal yield in Ghana and The Gambia, legume yield in Mali, ruminant numbers in Benin and The Gambia, and total farm income in ...

Annals of Gastroenterological Surgery, EarlyView.ABSTRACT Background Chemotherapeutic advances have increased opportunities for conversion surgery (CS) in unresectable locally advanced (UR‐LA) pancreatic cancer (PC). However, the optimal indications for CS remain unclear. Sarcopenia has been associated with poor outcomes in PC, except UR‐LA PC. Herein, we aimed to evaluate the impact of sarcopenia on

Reynolds and Mach number effects on multielement airfoils [PDF]
Experimental studies were conducted to assess Reynolds and Mach number effects on a supercritical multielement airfoil. The airfoil is representative of the stall-critical station of an advanced transport wing design.
