Deriving played trumpet directivity patterns from a multiple-capture transfer-function technique
Acta AcusticaThe directional radiation patterns of musical instruments have long been defining characteristics known to influence their perceived qualities. Technical understanding of musical instrument directivities is essential for applications such as concert hall

Optimizing an array of antennas for cellular coverage from a high altitude platform [PDF]
, 2003 In a wireless communications network served by a high altitude platform (HAP) the cochannel interference is a function of the antenna beamwidth, angular separation and. sidelobe level.

AAA+ protein unfoldases—the Moirai of the proteome
FEBS Letters, EarlyView.AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Influence of loudspeaker directivity on the measurement uncertainty [PDF]
, 2011 One of the most significant aspects of a building’s acoustic behavior is the airborne sound insulation of the room façades, since this determines the protection of its inhabitants against environmental noise.

Free-Space Antenna Field/Pattern Retrieval in Reverberation Environments
, 2005 Simple algorithms for retrieving free-space antenna field or directivity patterns from complex (field) or real (intensity) measurements taken in ideal reverberation environments are introduced and discussed.Comment: 6 pages, 2 figures, submitted to IEEE ...

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Model Analysis of FDD-LTE Forward Interference and Capacity
Dianxin kexue, 2015 The forward interference is an important factor that affects the FDD-LTE network capacity and user experience. FDD-LTE forward interference and capacity were analyzed. A forward interference model was proposed under various network loads.

Proceedings of the 1st Annual ACM Symposium on Computational Fabrication, 2017 The goal of display and screen manufacturers is to design devices or surfaces that maximize the perceived image quality, e.g., resolution , brightness, and color reproduction. Very often, a particular viewer location is not taken into account, and the quality is maximized across all viewing directions.
