Canonical Diffeomorphisms of Manifolds Near Spheres by Wang, Bing, Zhao, Xinrui

“…Abstract For a given Riemannian manifold $$(M^n, g)$$ ( M n , g ) which is near standard sphere $$(S^n, g_{round})$$ ( S n , g round ) in the Gromov–Hausdorff topology and satisfies $$Rc \ge n-1$$ R c ≥ n - 1 , it is known by Cheeger–Colding theory that M is diffeomorphic to $$S^n$$ S n . …”

Bio-based lubricant with additives: Tribological performances in hydrodynamic journal bearing by Norazman, Amanda, Paiman, Zulhanafi, Samion, Syahrullail, Afiq, Muhammad Noor, Muhammad Yazid, Witri, Rasep, Zuraidah

“…Purpose: The purpose of this paper is to investigate the performance of bio-based lubricants (BBL), namely, palm mid-olein (PMO) enriched with an antioxidant agent, tertiary-butylhydroquinone (TBHQ) and a viscosity improver, ethylene-vinyl acetate (EVA), in journal bearing (JB) applications. Design/methodology/approach: Samples of the BBL were prepared by blending it with TBHQ and EVA at various blending ratios. …”

Passive acoustic tracking of an unmanned underwater vehicle using bearing-Doppler-speed measurements by Kita, Kristen Railey, Randeni, Supun, DiBiaso, Dino, Schmidt, Henrik

“…The propeller rotation rate can be estimated from the motor signature and converted to speed using a pre-identified model of the robot. The bearing-Doppler-speed measurements outperformed traditional bearing-Doppler target motion analysis: the bearing, bearing rate, range, and range rate accuracy improved by a factor of 2×, 16×, 3×, and 6×, respectively. …”

Retinal projection near-eye displays with Huygens’ metasurfaces by Song, Weitao, Liang, Xinan, Li, Shiqiang, Moitra, Parikshit, Xu, Xuewu, Lassalle, Emmanuel, Zheng, Yuanjin, Wang, Yongtian, Paniagua-Domínguez, Ramón, Kuznetsov, Arseniy I.

“…The virtual image is generated using a visible laser illuminating a metasurface hologram, which is then directly projected onto the retina using an optical see-through eyepiece. Using this concept, this work experimentally demonstrates a compact and wearable near-eye display of light weight (≈50 g, including spectacle frames, light source, and battery) creating accommodation-free images (clear ranging from 0.5 to 2 m), overlaid with the real world and directly viewed by naked eye. …”
