Optimum design of speed control humps for vehicles.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1988 This paper deals with optimum design problems of humps for controlling vehicle speeds. Optimum humps are obtained for a segment of a circle in section using a method with a SUMT optimizing a hump for a vehicle. The objective of the design is to minimize the maximum acceleration of the driver occurring during a vehicle crossing a hump at a design speed ...

The Effect of Speed Humps on Highways Pavement Condition [PDF]
International Journal of Engineering, 2020 Speed humps used as a tool of traffic calming technique that applied to force drivers to reduce their vehicle’ speeds at some locations. For developed countries, the implementations of speed humps are often used within residential areas as well as at locations of schools crossing. For developing countries (e.g.

Advanced Science, EarlyView.A self‐supporting, biocompatible, and biodegradable 3D cellulose scaffold has been developed for efficient isolation and in situ expansion of circulating tumor cells (CTCs) from patient blood. Subsequently, the 3D cellulose scaffold with cultured CTCs is directly implanted into immunodeficient mice for constructing patient CTC‐derived xenograft (CDX ...

Advanced Science, EarlyView.An autologous whole‐tumor‐cell vaccine (rWTC‐MBTA) is evaluated in murine CNS lymphoma. Subcutaneous vaccination activates dendritic cells, broadens T‐cell priming, and drives lymphocyte trafficking to brain tumors, producing durable tumor control. Longitudinal bioluminescence and adoptive‐transfer assays verify CNS engagement. Combination with anti‐PD‐

Advanced Science, EarlyView.T cell‐specific Socs1 knockout leads to inflammatory differentiation of CD8+ T cells, prompting the STAT1/2 complex to drive the activation of Ccl5, Ccr5, and Cxcr3, and promoting the skewing of monocytes toward a pro‐inflammatory M1 macrophage lineage.

Distance between speed humps and pedestrian crossings: Does it matter?
Accident Analysis & Prevention, 2011 Speed humps are a common physical measure installed at pedestrian crossings to reduce vehicle speeds therefore improve the safety and mobility of pedestrians at the crossing. The aim of this study was to determine whether variations in distance between speed humps and pedestrian crossings contribute differently to the safety and mobility of pedestrians

Photon‐Sphere Modes in Curved Optical Microcavities: A Black‐Hole Analogue Laser
Advanced Science, EarlyView.An optical analogue of a Schwarzschild black hole is realized using curved microcavities that preserve light‐like geodesics. A new family of laser modes confined around the photon sphere is identified alongside conventional whispering‐gallery modes. Analytical theory, numerical simulations, and experiments reveal curvature‐induced confinement, enabling
