Traditional ecological knowledge and flood risk management: A preliminary case study of the Rwenzori
Jàmbá, 2018 The shift from flood protection to flood risk management, together with recent arguments on incorporating culture in managing risk, underscores the application of traditional ecological knowledge (TEK) in managing disasters from flood hazards.

Multi‐Channel Quantum Dot Single‐Photon Sources on a Fiber‐Integrated Platform
Advanced Optical Materials, EarlyView.A breakthrough in achieving a multiple, tunable array of quantum photonic devices is presented. By combining an optimal nanophotonic cavity, individual device transfer process, and integrated electrodes on a V‐groove fiber, the all‐fiber integrated system exhibits capabilities of low‐temperature cooling, efficient single‐photon transmission, selective ...

Advanced Optical Materials, EarlyView.This paper presents both experimental data and a theoretical model that correlates molecular structure with exciplex binding energy. The findings consistently demonstrate that large molecules with ionic charges localized at their edges exhibit low exciplex binding energies.

Design of a Bilayer Metalens for Red, Green, and Blue‐Achromatic Imaging with Wide Field of View
Advanced Photonics Research, EarlyView.Herein, an RGB‐achromatic bilayer metalens with a wide 80‐degree field‐of‐view and a high 0.65 numerical aperture is presented. Using silicon nitride meta‐atoms, it maintains consistent focal lengths for red, green, and blue light, even at oblique angles.

The moon as a symbol of death in "The Romance of the Moon, Moon"
Práxis Pedagógica, 2008 The following article is an approach to semiotic analysis of the artistic text, specifically the poem. It takes up the thesis that consider poetic language as an integral element of semiotics, not linguistics.

Techniques and Advances in Ultrafast Photography
Advanced Photonics Research, EarlyView.This review maps the fast‐growing field of ultrafast photography from early mechanical cameras to modern optical‐computational methods. It organizes techniques into four families (multishot passive/active; single‐shot passive/active), explains how they reach trillion‐frame‐per‐second speeds, compares capabilities and tradeoffs, and highlights ...
