Optimizing 3D Bin Packing of Heterogeneous Objects Using Continuous Transformations in SE(3)

Advanced Intelligent Systems, Volume 8, Issue 6, June 2026.
This article presents a method for solving the three‐dimensional bin packing problem for heterogeneous objects using continuous rigid‐body transformations in SE(3). A heuristic optimization framework combines signed‐distance functions, neural network approximations, point‐cloud bin modeling, and physics simulation to ensure feasibility and stability ...

A novel current-limiting hybrid DC breaker based on thyristors

Energy Reports, 2023
Since the DC current has no zero-crossing in high-voltage and large-capacity DC scenarios, and the low line impedance results in a large growth rate of fault current, the breaking requirements of DC circuit breakers (DCCB) are further increased.

Species‐specific processing of fluorescent dissolved organic matter by Caribbean sponges

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Coral reefs are biodiverse and productive ecosystems that are found in typically oligotrophic environments. Many studies have attempted to explain this paradox by demonstrating that microbial symbionts expand metabolic capabilities of host animals.

New Computational Method for Optimal Allocation of Fault Current Limiters in Power Systems

Iranian Journal of Electrical and Electronic Engineering, 2021
Expansion of power system causes short-circuit currents (SCC) of networks to exceed the tolerable SCCs of equipment. The utilization of fault current limiter (FCL) in such networks is needed to address this issue.

A Mathematical Approach to Simultaneously Plan Generation and Transmission Expansion Based on Fault Current Limiters and Reliability Constraints

Mathematics, 2021
Today, generation and transmission expansion planning (G&TEP) to meet potential load growth is restricted by reliability constraints and the presence of uncertainties.

A genome‐integrated CRISPR/Cas12a system enables efficient genetic engineering in Xenorhabdus budapestensis XBD8

New Plant Protection, Volume 3, Issue 2, June 2026.
We developed a genome‐integrated CRISPR/Cas12a system for Xenorhabdus budapestensis XBD8, which enables precise deletion or replacement of DNA fragments ranging from 379 to 45,168 bp, with a success rate exceeding 90%. Application of this tool for the dynamic regulation of fabclavine‐8 biosynthesis resulted in a 1.90‐fold increase in production ...

Optimal overcurrent relay coordination: Balancing costs, time performance and generator placement in fault current limiter optimization

IET Generation, Transmission & Distribution
The integration of synchronous generators (SG) to the grid will present serious problems in some instances. The increase in fault current level is one of the most crucial issues, which causes miscoordination between directional over current relays (DOCRs)

Structural Recovery of Overlooked Shrublands Drives Asymmetric Restoration in Dryland Ecosystems

Earth's Future, Volume 14, Issue 6, June 2026.
Abstract Current remote sensing of dryland ecosystems is fundamentally limited by a reliance on vegetation indices (“greenness”), which struggle to disentangle mixed pixel signals and fail to capture the non‐photosynthetic structural components critical for resilience.

Implementation of Series Resonance-Based Fault Current Limiter for Enhanced Transient Stability of Grid-Connected Photovoltaic Farm

Electronics
This paper presents the implementation of an improved resonance-type FCL, designed to enhance the transient stability of a photovoltaic farm. This FCL overcomes the well-known drawbacks associated with the conventional resonance-based FCLs.
