We have shown that when sharply focusing a linearly polarized optical vortex with topological charge 2, in the near-axis region of the focal plane, not only does a reverse energy flow (the negative on-axis projection of the Poynting vector) occur, but also the right-handed circular polariza-tion of light.Moreover, due to Mens pant spin-orbital angu
We present measurements of the spatiotemporal evolution of a hot-dense plasma generated by the interaction of an intense 25 fs laser pulse with a solid Cot Sheets target, using pump-probe two-dimensional (2D) Doppler spectrometry.Measuring the time-dependent Doppler shifts at different positions across the probe beam, we achieve velocity mapping at
Abstract Background Circular RNAs (circRNAs) have emerged as vital regulators Serum of the initiation and progression of diverse kinds of human cancers.In this study, we explored the role of hsa_circ_0000231 and its downstream pathway in CRC.Methods The expression profile of circRNAs in 5 pairs of CRC tissues and adjacent normal tissues were analyz
Background: A large proportion of logistics jobs still rely on manual labor and therefore place a physical strain on employees.This includes the handling of heavy goods and physiologically unfavorable postures.Such issues pose a risk for employee health and work capability.This article provides a detailed empirical analysis and a decision process s
Video capsule endoscopy (VCE) is used widely nowadays for visualizing the gastrointestinal (GI) tract.Capsule endoscopy exams are prescribed usually as an additional monitoring mechanism and can help in identifying polyps, bleeding, etc.To analyze the large scale video data produced by VCE exams, automatic image processing, computer vision, and lea
