Broad Skills, Smaller Footprints? Generalist CEOs and Firm Biodiversity Exposure
Business Strategy and the Environment, EarlyView.ABSTRACT We examine whether CEO generalist skills predict firm‐level biodiversity risk exposure, an emerging strategic and financial concern. Using the biodiversity indicator developed based on textual analysis and the General Ability Index, we find that firms led by generalist CEOs are associated with significantly lower disclosed biodiversity risk ...

Involuntary Railway Crossing Controller
International Journal of Innovative Technology and Exploring Engineering, 2019 The main motive of this paper is to present an involuntary railway crossing controller that turn on and off the gates during crossing of trains. This reduces the physical efforts made by the gate keeper and saves a lot of time as well as money. In present times the station master has to communicate with gatekeeper to inform him to close gate and if ...

Laser-Based Obstacle Detection at Railway Level Crossings [PDF]
Journal of Sensors, 2016 This paper presents a system for obstacle detection in railway level crossings from 3D point clouds acquired with tilting 2D laser scanners. Although large obstacles in railway level crossings are detectable with current solutions, the detection of small obstacles remains an open problem.

New Insights Into the Three‐Dimensional Mechanics of the Flagellar Beat Cycle
Cytoskeleton, EarlyView.ABSTRACT Advances in imaging at the molecular scale have provided greater detail concerning the three‐dimensional structure of the ciliary/flagellar axoneme. Additionally, it has recently been confirmed that electrostatic forces regulate the dynein‐tubulin interaction at the microtubule binding domain (MTBD) of dynein, and at the junction of the nexin ...
