“Somewhere in California”: New Regional Spaces of Mobility in Contemporary Vancouver Cinema by Katherine A. Roberts

“…Through caustic humor, the films engage in multiple levels of critique: of the dysfunctional nature of these cross-border families, but also of the superficiality of image-culture and the “forced” migration of talent who are sucked into the entertainment vortex. Analyzing these films through the lens of critical regionalism foregrounds “West Coastness” as a region of flows, of bodies in mobility/circulation yet—in the case of Bessai—without side-stepping the obvious asymmetries inherent in Canada’s complex and enduringly ambivalent relationship with the United States.…”

Effects of Flow Coefficient on Turbine Aerodynamic Performance and Loss Characteristics by Shaoyun Yang, Wei Du, Lei Luo, Songtao Wang

“…The difference is that with large stagger angle, the adverse pressure gradient affects a large area, resulting in large boundary layer losses; with large exit angle, the passage vortex is weakened but with a large influence area.…”

ANALYSIS OF TRANSIENT CLOSING PROCESS AND COLLISION RESPONSE OF SWING CHECK VALVE by ZHANG XiHeng, ZHANG SunLi, BAI YaZhou, ZHANG XiaoKang

“…Through analysis,it was shown that the fluid backflow has a hysteresis,the movement speed of the valve flap shows a parabolic rise,and the dynamic torque presents a process of slowly decreasing to suddenly increasing in the reverse direction when the valve is closing. Vortex phenomenon obvious occurs at the bottom of the valve flap,and there is a time difference in the change of fluid flow direction on the center line of the flow channel; In the process of collision and rebound,the peak stress appeared at the rounded corners of the back of the flap and the rocker rib,and the valve flap swings slightly and collides with the valve seat many times in a short time. …”

OUTSIDE REARVIEW MIRROR PANORAMIC CAMERA POSITION ON THE AERODYNAMIC CHARACTERISTICS OF IMPACT STUDY by TONG GaoPeng, GAN Wei, LI ZhiWei, LIN Hui, WANG ZhiFeng

“…In order to reduce the influence of the panorama camera on the aerodynamic noise of the vehicle,the exterior flow field and sound field analysis are carried out on the rearview mirror of three different lens placement positions.The calculated results are in good agreement with the experimental data,which verifies the reliability of the numerical simulation.At the same time,it is found that the different position of the panoramic lens has an influence on the air flow which through the exterior mirrors,thus changing the rear flow field and the front window noise radiation intensity.Scheme Ⅲ is compared with other schemes,the tail vortex,the turbulence kinetic energy and the noise emission of the front window are relatively weaker,which can reduce the aerodynamic noise.Finally,by comparing the noise test of three kinds of schemes,it is found that the noise of scheme Ⅲ is lower than that of other schemes,which verifies the correctness of the analysis method.The analysis results provides the guidance for the reasonable arrangement of the rearview mirror panorama image lens,and is favorable for improving the comfort of the driver.…”

Alignment-induced self-organization of autonomously steering microswimmers: Turbulence, clusters, vortices, and jets by Segun Goh, Elmar Westphal, Roland G. Winkler, Gerhard Gompper

“…Pullers exhibit a strong tendency for clustering and display velocity and vorticity distributions with fat exponential tails; their dynamics is chaotic, with a temporal appearance of vortex rings and fluid jets. Our results show that the collective behavior of autonomously steering microswimmers displays a rich variety of dynamic self-organized structures. …”

Difference equations: From Berry connections to the Coulomb branch by Andrea E. V. Ferrari, Daniel Zhang

“…This action could be quantised to first-order matrix difference equations obeyed by brane amplitudes, and by taking the conformal limit, vortex partition functions. In this article, we elucidate how some of these results may be recovered from a 3d perspective, by placing the 2d theory at a boundary and gauging the flavour symmetry via a bulk A-twisted 3d $\mathcal{N}=4$ gauge theory (a sandwich construction). …”
