Driving Mechanisms, Motion, and Mechanics of Screw Drive In-Pipe Robots: A Review
Applied Sciences, 2019 In recent years, interest in in-pipe robot research has been steadily increasing. This phenomenon reflects the necessity and urgency of pipe inspection and rehabilitation as several pipe networks have become outdated around the globe.

Erlangen Programme at Large 3.1: Hypercomplex Representations of the Heisenberg Group and Mechanics [PDF]
, 2011 In the spirit of geometric quantisation we consider representations of the Heisenberg(--Weyl) group induced by hypercomplex characters of its centre. This allows to gather under the same framework, called p-mechanics, the three principal cases: quantum ...

Complex Correspondence Principle [PDF]
, 2009 Quantum mechanics and classical mechanics are two very different theories, but the correspondence principle states that quantum particles behave classically in the limit of high quantum number.

Evading Quantum Mechanics à la Sudarshan: quantum-mechanics-free subsystem as a realization of Koopman-von Neumann mechanics [PDF]
Found. Phys. 53 (2023), 92, 2023 Tsang and Caves suggested the idea of a quantum-mechanics-free subsystem in 2012. We contend that Sudarshan's viewpoint on Koopman-von Neumann mechanics is realized in the quantum-mechanics-free subsystem. Since quantum-mechanics-free subsystems are being experimentally realized, Koopman-von Neumann mechanics is essentially transformed into an ...

Machine Learning for Fluid Mechanics [PDF]
Annual Review of Fluid Mechanics, 2019 The field of fluid mechanics is rapidly advancing, driven by unprecedented volumes of data from experiments, field measurements, and large-scale simulations at multiple spatiotemporal scales. Machine learning (ML) offers a wealth of techniques to extract

HP1α is a chromatin crosslinker that controls nuclear and mitotic chromosome mechanics
eLife, 2021 Chromatin, which consists of DNA and associated proteins, contains genetic information and is a mechanical component of the nucleus. Heterochromatic histone methylation controls nucleus and chromosome stiffness, but the contribution of heterochromatin ...

On obtaining classical mechanics from quantum mechanics [PDF]
, 2006 Constructing a classical mechanical system associated with a given quantum mechanical one, entails construction of a classical phase space and a corresponding Hamiltonian function from the available quantum structures and a notion of coarser observations.

Emergence of a geometric pattern of cell fates from tissue-scale mechanics in the Drosophila eye
eLife, 2022 Pattern formation of biological structures involves the arrangement of different types of cells in an ordered spatial configuration. In this study, we investigate the mechanism of patterning the Drosophila eye epithelium into a precise triangular grid of

eLife, 2022 During cell division, the spindle generates force to move chromosomes. In mammals, microtubule bundles called kinetochore-fibers (k-fibers) attach to and segregate chromosomes. To do so, k-fibers must be robustly anchored to the dynamic spindle.

The Relationship between First and Second Language Literacy in Writing [PDF]
Journal of Applied Linguistics, 2008 This paper explores the ways in which the transfer of assumptions from first language (L1) writing can help the process of writing in second language (L2).
