Fiber Microsphere Coupled in a Taper for a Large Curvature Range
This work consists of using an optical fiber microsphere as a sensor for a wide range of curvature radii. The microsphere was manufactured in a standard fiber with an electric arc.

In porous media, pore geometry and wettability are determinant factors for capillary flow in drainage or imbibition. Pores are often considered as cylindrical tubes in analytical or computational studies.

Two-Step Method for Assessing Similarity of Random Sets
The paper concerns a new statistical method for assessing dissimilarity of two random sets based on one realisation of each of them. The method focuses on shapes of the components of the random sets, namely on the curvature of their boundaries together ...

Abel–Jacobi map and curvature of the pulled back metric
Let X be a compact connected Riemann surface of genus at least two. The Abel–Jacobi map φ:Symd(X)→Picd(X) is an embedding if d is less than the gonality of X. We investigate the curvature of the pull-back, by φ, of the flat metric on Picd(X).

Load Distribution in the Lumbar Spine During Modeled Compression Depends on Lordosis
Excessive or incorrect loading of lumbar spinal structures is commonly assumed as one of the factors to accelerate degenerative processes, which may lead to lower back pain.

Spinal shape analysis in 1,020 healthy young adults aged from 19 to 30 years
Background: A number of studies on diseased spine have been published; however, there is a relative paucity of studies investigating spine shape characteristics in healthy populations.

Estimating the Rut Depth by UAV Photogrammetry
The rut formation during forest operations is an undesirable phenomenon. A methodology is being proposed to measure the rut depth distribution of a logging site by photogrammetric point clouds produced by unmanned aerial vehicles (UAV).

Study of Morphometry of Carotid Canal in Skulls of South Indian origin [PDF]
Background: The internal carotid artery supplies the anterior part of the brain, the eye and its appendages and sends branches to the forehead and nose.Carotid canal is a curved channel in the petrous temporal bone through which internal carotid ...

Novel Topological Phase with a Zero Berry Curvature. [PDF]
We present a two-dimensional (2D) lattice model that exhibits a nontrivial topological phase in the absence of the Berry curvature. Instead, the Berry connection provides the topological nontrivial phase in the model, whose integration over the momentum ...

The Lemon Illusion: Seeing curvature where there is none
Curvature is a highly informative visual cue for shape perception and object recognition. We introduce a novel illusion—the Lemon Illusion—in which subtle illusory curvature is perceived along contour regions that are devoid of physical curvature.
