Resolving front-back ambiguity with head rotation: The role of level dynamics [PDF]
Making small head movements facilitates spatial hearing by resolving front-back confusions, otherwise common in free field sound source localization. The changes in interaural time difference (ITD) in response to head rotation provide a robust front-back cue, but whether interaural level difference (ILD) can be used as a dynamic cue is not clear ...

Effect rules of aft propeller pitch angle on the performance of contra rotation propeller [PDF]
The pitch angle of the contra rotation propeller (CRP) has important effect on the aerodynamic interference between the front and aft blades,which can change the aerodynamic performance of the propeller.

Distinct Neural Dynamics of Spatial Transformations: Egocentric Perspective-Taking and Allocentric Rotation [PDF]
Background/Objectives: Egocentric and allocentric spatial transformations are central to spatial cognition, yet it is unknown whether they rely on the same neural mechanisms. The goal of this study was to examine whether egocentric transformations engage

Wick rotation in the light-front [PDF]
Dep. de Fisica, Instituto Tecnologico de Aeronautica, 12.228-900,Sao Jose dos Campos, BrazilE-mail:pacheco@ift.unesp.brWe study the electroweak properties of pseudo-scalar mesons in the light and heavy-light sec-tors. In particular, we address the electromagnetic form factors and decay constants of the pion,kaon and D mesons. The structure of composite

On rotations in front-form dynamics [PDF]
Quantum field theories in front-form dynamics are not manifestly rotationally invariant. We study a model bound-state equation in 3+1 dimensional front-form dynamics, which was shown earlier to reproduce the Bohr and hyperfine structure of positronium.

Flow mechanism and axial force distribution characteristics of multistage pump cavity
The gap leakage between the impeller ring leads to the change of the pump cavity flow characteristics, resulting in the uneven pressure distribution of shroud, which causes the axial force of the cavity to change. In this paper, the flow in the front and

Research on Design and Dynamics Simulation of Hinged Drooping Leading Edge Mechanism
The drooping front leading edge is a simple lifting device,which can effectively reduce the aerodynamic noise and the motion space of the mechanism. It has been applied to A380 and A350XW.
