Bi-Lipschitz embedding metric triangles in the plane
Analysis and Geometry in Metric SpacesA metric polygon is a metric space comprised of a finite number of closed intervals joined cyclically. The second-named author and Ntalampekos recently found a method to bi-Lipschitz embed an arbitrary metric triangle in the Euclidean plane with ...

Upright-Quad Drawing of st-Planar Learning Spaces
Journal of Graph Algorithms and Applications, 2008 We consider graph drawing algorithms for learning spaces, a type of st-oriented partial cube derived from an antimatroid and used to model states of knowledge of students.

Advanced Materials Technologies, EarlyView.Transparent, electrically conductive In–Zn–O thin films are solution‐processed by spin coating, inkjet printing, and, as demonstrated here for the first time, screen printing. The chosen deposition technique determines the solution composition, which in turn governs the resulting microstructure and optoelectronic performance.

Relationship between the perimeter and the area of convex quadrilaterals [PDF]
, 2020 In the master's thesis, we will present the relation between the perimeter and the area for convex quadrilaterals. Using the equation p = 1/2or, where o is the perimeter and r is the radius of the incircle, we will represent the relation between the ...

Advanced Materials Technologies, EarlyView.Electric‐field‐assisted spin coating is introduced as a wet‐film processing route for guiding perovskite crystallization. A transient perpendicular field produces distinct structural maxima rather than monotonic grain growth: largest scanning electron microscopy (SEM)‐derived grain size at nominal 2 kV cm−1${\rm cm}^{-1}$, largest X‐ray diffraction ...

Advanced Robotics Research, EarlyView.Intelligent Sky Guardians (InSkyGuard) is introduced as a four‐drone swarm that autonomously detects, tracks, and safely captures rogue drones using a coordinated net system. Computer vision and leader–follower control architecture enable synchronized enclosure, while integrated failsafes enhance system reliability. Validated through closed‐environment

Further characterisations of tangential quadrilaterals
, 2017 Tangential quadrilaterals are defined to be quadrilaterals in which a circle can be inscribed that is tangent to all four sides. It is well known and easy to prove that a convex quadrilateral is tangential if, and only if, the angle bisectors of all four

A Soft, Flexible Implant for Wireless Photothermal–Pyroelectric Neurostimulation
Advanced Science, EarlyView.A replication strategy is used to enlarge the exposed surface area of barium titanate within flexible films with embedded carbon nanotubes, enabling efficient photothermal‐pyroelectric stimulation. Polar crystalline nanosheets show superior performance in guiding neural progenitor cells toward neuronal differentiation.

Polymorphic Superparaelectric Engineering Boosting Energy Storage Capacity in BaTiO3‐Based Ceramics
Advanced Science, EarlyView.Herein, Ca2+ incorporation promotes the coexistence of CaTiO3‐/BaTiO3‐derived paraferroelectric states, stabilizing cubic‐orthorhombic‐tetragonal polymorphic superparaelectric phases. This minimizes polarization energy barriers, facilitating full polarization saturation without compromising efficiency.
