Multipolar Resonances in Electro‐Optic Metasurfaces with Moderate Refractive Index

open access: yesAdvanced Photonics Research, EarlyView.
Electro‐optic nanoantennas with moderate refractive indices of 2.3 to 3.0 are numerically shown to sustain strong multipolar resonances, enabling efficient light confinement and EO tuning. Multipolar modes of even parity are most sensitive to variations in the refractive index.

Gait Analysis of Pak Biawak: A Necrobot Lizard Built using the Skeleton of an Asian Water Monitor (Varanus Salvator)

open access: yesAdvanced Robotics Research, EarlyView.
Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

Locating remediation and restoration operations with MCDM and AHP and ANP methods (case study: Saqezchi-Chay watershed in Namin city) [PDF]

open access: yesمطالعات جغرافیایی مناطق خشک
Aim: Saqezchi-Chay watershed is important because of suitable ecological factors, high plant and animal production, and a water reservoir dam in the outlet part of this watershed. However, it is heavily used, overgrazed, and degraded.
