Ecography, EarlyView.Globally, mountains are highly diverse ecosystems that serve as natural laboratories for testing ecological theories, while providing vital ecosystem services. Their biodiversity arises from the interaction between elevational gradients and topographic complexity, which generate strong variation in environmental conditions across short spatial scales ...

Noncollision Periodic Solutions for Circular Restricted Planar Newtonian Four-Body Problems
MathematicsWe study a class of circular restricted planar Newtonian four-body problems in which three masses are positioned at the vertices of a Lagrange equilateral triangle configuration, each mass revolving around the center of mass in circular orbits.

Heat Transfer, EarlyView.ABSTRACT This study investigates the thermal performance of innovative biphilic boiling surfaces designed for CPU cooling applications using a two‐phase closed thermosyphon (TPCT) system. The surfaces were fabricated by applying composite coatings—comprising epoxy resin and diatomite particles functionalized with APTES and PFOTS silanes— onto Al1050 ...

COLORING EQUILATERAL TRIANGLES
The Journal of Symbolic LogicAbstract It is consistent relative to an inaccessible cardinal that ZF+DC holds, the hypergraph of equilateral triangles on a given Euclidean space has countable chromatic number, while the hypergraph of isosceles triangles on $\mathbb {R}^2$ does not.

An Alpha Particle Model for Carbon-12
, 2018 We introduce a new model for the Carbon-12 nucleus and compute its lowest energy levels. Our model is inspired by previous work on the rigid body approximation in the $B=12$ sector of the Skyrme model.

Nano‐Raman Spectroscopy of Tellurium Nanowires
Journal of Raman Spectroscopy, EarlyView.Nano‐Raman evidences a diameter dependence of the peak position, among different tellurium nanowires and along the single species. ABSTRACT Tellurium‐based nanowires are interesting structures for applications in low‐dimensional electronics. This work investigates the vibrational dynamics of trigonal tellurium (t‐Te) nanowires through tip‐enhanced ...

Evaluation of Static Potential Integrals on Triangular Domains
IEEE Access, 2020 Static potential integrals for constant and linear sources on triangles are derived in a straightforward way. The new representations, as presented, are robust with respect to machine evaluation in important limiting cases.
