Nodal domains of the equilateral triangle billiard
, 2014 We characterise the eigenfunctions of an equilateral triangle billiard in terms of its nodal domains. The number of nodal domains has a quadratic form in terms of the quantum numbers, with a non-trivial number-theoretic factor.

Tiling Convex Polygons with Congruent Equilateral Triangles [PDF]
Discrete & Computational Geometry, 2014 The authors of this paper establish some results for tiling convex polygons with congruent equilateral triangles. They give a complete characterization under the assumption of the generalized Riemann hypothesis.

Advanced Materials Technologies, EarlyView.A high‐density wearable body‐surface potential mapping array reveals how gravity reshapes cardiac conduction in real time. By resolving spatiotemporal delay patterns invisible to conventional ECG, the platform uncovers posture‐dependent electrophysiological adaptations across the thorax.

ISOSCELES TRIANGLES ON THE SIDES OF A TRIANGLE
Human Research in Rehabilitation, 2019 Famous construction of Fermat-Toricelly point of a triangle leads to the question is there a similar way to construct other isogonic centers of a triangle in a similar way.

Primordial non-Gaussianity and the CMB bispectrum [PDF]
, 2006 We present a new formalism, together with efficient numerical methods, to directly calculate the CMB bispectrum today from a given primordial bispectrum using the full linear radiation transfer functions.

Equilateral Triangles in Finite Metric Spaces [PDF]
The Electronic Journal of Combinatorics, 2004 In the context of finite metric spaces with integer distances, we investigate the new Ramsey-type question of how many points can a space contain and yet be free of equilateral triangles. In particular, for finite metric spaces with distances in the set $\{1,\ldots,n\}$, the number $D_n$ is defined as the least number of points the space must contain ...

Autonomous Locomotion of Tensegrity Structure on Low‐Temperature Surfaces
Advanced Robotics Research, EarlyView.A low‐temperature responsive tensegrity structure (LRTS) is constructed by integrating low‐responsive temperature liquid crystal elastomer (LCE) cables, nonresponsive cables, and stiff rods. The low phase transition temperature of LCE is achieved by introducing a new liquid crystal mesogen.

Optimizing Node Localization in Wireless Sensor Networks Based on Received Signal Strength Indicator
IEEE Access, 2019 In order to improve the precision of inside localization and optimize the allocation of node resources in wireless sensor networks (WSNs), an equal-arc trilateral localization algorithm based on received signal strength indicator (RSSI) is proposed from ...

The Angular Resolution of Space-Based Gravitational Wave Detectors
, 2000 Proposed space-based gravitational wave antennas involve satellites arrayed either in an equilateral triangle around the earth in the ecliptic plane (the ecliptic-plane option) or in an equilateral triangle orbiting the sun in such a way that the plane ...
