Jerk and Hyperjerk in a Rotating Frame of Reference [PDF]

open access: yes, 2015
Jerk is the derivative of acceleration with respect to time and then it is the third order derivative of the position vector. Hyperjerks are the n-th order derivatives with n>3.

Spatial reference frame agreement in quantum networks

open access: yesNew Journal of Physics, 2014
In order to communicate information in a quantum network effectively, all network nodes should share a common reference frame. Here, we propose to study how well m nodes in a quantum network can establish a common spatial reference frame from scratch ...

Perspectivism and Special Relativity

open access: yesTeorie vědy, 2021
The special theory of relativity holds significant interest for scientific perspectivists. In this paper, I distinguish between two related meanings of “perspectival,” and argue that reference frames are perspectives, provided that perspectival means ...

Quantum communication using a bounded-size quantum reference frame

open access: yes, 2009
Typical quantum communication schemes are such that to achieve perfect decoding the receiver must share a reference frame with the sender. Indeed, if the receiver only possesses a bounded-size quantum token of the sender's reference frame, then the ...

High-speed Video from Asynchronous Camera Array [PDF]

open access: yes, 2019
This paper presents a method for capturing high-speed video using an asynchronous camera array. Our method sequentially fires each sensor in a camera array with a small time offset and assembles captured frames into a high-speed video according to the ...

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

open access: yesFEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

An Accurate Multi-Row Panorama Generation Using Multi-Point Joint Stitching

open access: yesIEEE Access, 2018
Most of the existing panorama generation tools require the input images to be captured along one direction, and yield a narrow strip panorama. To generate a large viewing field panorama, this paper proposes a multi-row panorama generation (MRPG) method ...

Egocentric and Allocentric Reference Frames Can Flexibly Support Contextual Cueing

open access: yesFrontiers in Psychology, 2021
We investigated if contextual cueing can be guided by egocentric and allocentric reference frames. Combinations of search configurations and external frame orientations were learned during a training phase.

Nutation and Reference Frame [PDF]

open access: yesHighlights of Astronomy, 1995
The reference frames are of fundamental importance in all kinds of the precession and nutation studies involving the theory, the coordinate transformation and the observations. The aim of this paper is to review all the frames used in such studies and to lead to a better consistency between them in order that theory and reductions of observations be ...
