Discrete Chiral Ballistic Polariton Laser
Planar microcavities in the strong light–matter coupling regime exhibit exciton‐polariton modes with a strong chiral response toward circularly polarized light. This feature is exploited alongside inherent spin‐orbit coupling of cavity light to generate giant discrete optical vortices in polygonal arrays of exciton‐polariton condensates.

Using a Small Hexapod Robot to Pick up Large Cylinders for Munitions Response
ABSTRACT In shallow water environments, traditional technologies face challenges in retrieving unexploded ordnance (UXO). We present an innovative and safe alternative robotic platform to replace traditional divers in this dangerous task. A waterproof 18‐DOF legged robot MR.

A Framework to Enable Eco‐Cyber‐Physical Systems for Robotics‐Focused Digital Twins in Smart Farming
ABSTRACT This paper introduces the R‐ECPS (Robotics‐focused Eco‐Cyber‐Physical System) framework for the development of robotics‐enabled digital twins, integrating human knowledge into the decision‐making process. Our framework adapts ECPS and Digital Twin (DT) definitions to agricultural field robotics.

A Path Planning Algorithm Based on Tangent Point Search and Constrained B‐Spline
ABSTRACT The traditional Tangent Point Search (TPS) algorithm, as a path planning algorithm suitable for large‐scale maps, performs well in the presence of large rectangular obstacles. However, it has two disadvantages: 1. it requires that the obstacles be rectangular so that the shape of obstacles is limited to the fixed form. 2.

Optimizing Modem Placement in UPI Building FPMIPA using the Illumination Model
Since a reliable internet signal has become an essential and significant need nowadays, the existence of modems as transmitters of internet signals is also crucial; modems transmit the internet signal (without cable), which is then captured by devices ...

Hyperspectral imaging has a limited ability to remotely sense the onset of beech bark disease
Although hyperspectral imaging is a powerful remote sensing tool, it proved ineffective in predicting the progression of beech bark disease, except in its later stages, both at the canopy and leaf levels. While some alterations in chlorophyll, water content, and canopy structure may have influenced foliar reflectance at the canopy scale, as suggested ...

Fine‐tuning the composition of Ag8GeS6 quantum dots result in the development of near‐IR photoluminescence. The PL intensity is significantly enhanced by coating with a ZnS shell, enabling 3D near‐IR in vivo bioimaging. Abstract Quantum dots (QDs) composed of a group I–IV–VI semiconductor, Ag8GeS6, have been intensively investigated for constructing ...

Abstract This study examines the time‐dependent behavior of reinforced and prestressed concrete structures using integral‐ and rate‐type formulations, applying the concrete creep and steel relaxation models from the fib Model Code 2020. The stress–strain law for aging concrete is expressed by a second‐order differential equation, but a single rate‐type

Multiple management strategies exist to combat bird damage to agriculture. We explored combining two tools, drones as frightening devices and an avian repellent, to assess effectiveness of an integrated method to deter large flocks on complex landscapes. We evaluated the ability of a spraying drone (DJI Agras MG‐1P) deploying Avian Control (i.e. active
