Significance Few studies have asked at what spatial scale environmental stimuli regulate plant development and when during the patterning process these signals act. We discovered that roots can sense microscale heterogeneity in water availability across their circumference, which causes dramatic differences of tissues along this axis. Root branching is a target such hydropatterning; lateral only form on side main root contacting soil or agar. show hydropatterning conserved Arabidopsis ,...
Reverberation chambers used for acoustical measurements should have completely random sound fields. We denote by R the cross-correlation coefficient pressures at two points a distance r apart. = 〈p1p2〉Av/(〈p12〉Av〈p22〉Av)12, where p1 is pressure one point, p2 that other, and angular brackets long time averages. In field, (sinkr)/kr, k 2π/(the wavelength of sound). An instrument measuring recording as function described. A feature this use recorder's servomechanism to measure ratio dc...
Abstract Previous studies investigating the effect of aspect ratio ( $\mathit{AR}$ ) for insect-like regimes have reported seemingly different trends in aerodynamic forces, however no detailed flow observations been made. In this study, and Reynolds number on structures over wings is explored using a numerical model an altered fruit fly wing revolving at constant angular velocity. Increasing 2.91 resulted development dual leading-edge vortex (LEV) structure, increasing fixed generated same...
Abstract While the wake of a circular cylinder and, to lesser extent, normal flat plate have been studied in considerable detail, wakes elliptic cylinders not received similar attention. However, from first two bodies considerably different characteristics, terms three-dimensional transition modes, and near- far-wake structure. This paper focuses on cylinders, which span these disparate cases. The Strouhal number drag coefficient variations with Reynolds are documented for two-dimensional...
A liquid marble micro‐bioreactor is prepared by placing a drop of murine embryonic stem cell (ESC) (Oct4B2‐ESC) suspension onto polytetrafluoroethylene (PTFE) particle bed. The Oct4B2‐ESC aggregates to form embryoid bodies (EBs) with relatively uniform size and shape in within 3 d. For the first time, feasibility differentiating ESC into cardiac lineages marbles being investigated. Without addition growth factors, suspended EBs from express various precardiac mesoderm markers including...
Flow transitions are an important fluid-dynamic phenomena for many reasons, including the direct effect on aerodynamic forces acting body. In present study, two-dimensional (2-D) and three-dimensional (3-D) wake of a NACA0012 airfoil studied angles attack in range $0^\circ \leq \alpha 20^\circ$ Reynolds numbers $500 {\textit {Re}} 5000$ . The study uses water-channel experiments 2-D 3-D numerical simulations based nodal spectral-element method, level-set function-based immersed-interface...
Two-dimensional flow past a cylinder close to free surface at Reynolds number of 180 is numerically investigated. The wake behaviour for Froude numbers between 0.0 and 0.7 gap ratios 0.1 5.0 examined. For low numbers, where the deformation minimal, simulations reveal that this problem shares many features in common with no-slip wall. This suggests largely governed by geometrical constraints low-Froude-number limit.At excess 0.3–0.4, becomes substantial. can be traced increases local unity or...
The low-Reynolds-number wake dynamics and stability of the flow past toroids placed normal to direction are studied numerically. This bluff body has attractive feature behaving like sphere at small aspect ratios, locally straight circular cylinder large ratios. Importantly, geometry ring is described by a single parameter, ratio (, initial asymmetric transition structurally analogous mode A for cylinder, with discontinuity present in Strouhal–Reynolds-number profile. numerical study reveals...
This paper reports on an extensive parameter space study of two-dimensional simulations a circular cylinder forced to oscillate transverse the free-stream. In particular, extent primary synchronization region, and wake modes energy transfer between body fluid are analyzed in some detail. The frequency range region is observed be dependent Reynolds number, as obtained. Energy primarily at low amplitudes oscillation, but amplitude high oscillation. However, oscillation corresponding zero found...
A Floquet stability analysis of the transition to three-dimensionality in wake a cylinder forced oscillate transversely free stream has been undertaken. The effect varying oscillation amplitude is determined for frequency close natural shedding frequency. three-dimensional modes that arise are identified, and on their structure growth rate quantified. It shown when two-dimensional 2 S configuration (which similar Kármán vortex street), nature symmetry fixed cylinder. These known as A, B QP...
Abstract Three-dimensional flows around a full-scale cyclist mannequin were investigated experimentally to explain the large variations in aerodynamic drag that are measured as legs positioned $360^\circ $ crank cycle. It is found dominant mechanism affecting not small variation frontal surface area over pedal stroke but rather due changes flow structure This clearly shown by series of detailed velocity field wake surveys and skin friction visualizations. Two characteristic regimes...
While it has been known that an afterbody (i.e. the structural part of a bluff body downstream flow separation points) plays important role affecting wake characteristics and even may change nature flow-induced vibration (FIV) structure, question whether is essential for occurrence one particular common form FIV, namely vortex-induced (VIV), still remains. This motivated present study to experimentally investigate FIV elastically mounted forward- or backward-facing D-section (closed...
