Generation, Ranking and Unranking of Ordered Trees with Degree Bounds [PDF]
Electronic Proceedings in Theoretical Computer Science, 2016 We study the problem of generating, ranking and unranking of unlabeled ordered trees whose nodes have maximum degree of Δ. This class of trees represents a generalization of chemical trees. A chemical tree is an unlabeled tree in which no node has degree

Individualized Pathfinding in Rugged Open Terrains Using Semantic Navigation Meshes
Computer Graphics Forum, EarlyView.We introduce semantic navigation meshes for complex outdoor terrains, partitioning space into regions with coherent semantic properties like slope or vegetation density. The resulting graphs enable efficient pathfinding with agent‐specific, parameterized cost functions without precomputation, accelerating search while maintaining path quality close to ...

A New Strategy to Design Reconfigurable Rivest–Shamir–Adleman (RSA) Accelerators
International Journal of Circuit Theory and Applications, Volume 54, Issue 6, Page 3043-3054, June 2026.A reconfigurable FPGA‐based RSA accelerator is proposed using compression‐based modular multipliers combined with pseudomoduli arithmetic. The approach maps modular exponentiation to low‐cost arithmetic domains and applies a correction stage, achieving significant improvements in delay, operating frequency, and delay–area efficiency compared with ...

Analysis of the Perfect Table Fuzzy Rainbow Tradeoff
Journal of Applied Mathematics, 2014 Cryptanalytic time memory tradeoff algorithms are tools for inverting one-way functions, and they are used in practice to recover passwords that restrict access to digital documents. This work provides an accurate complexity analysis of the perfect table

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract We present large‐scale simulations of energetic neutral atom (ENA) emissions at Uranus from a spacecraft viewpoint. Models of magnetic field, extended hydrogen exosphere, moon‐sourced neutral tori, and proton radiation belt are implemented into a simulator to evaluate the production of ENAs for L $L$ = 1–15.

Obstacle‐Aware Fluid Control via Vector Potential Editing
Computer Animation and Virtual Worlds, Volume 37, Issue 3, May/June 2026.This paper introduces a near real‐time framework for inserting obstacles into pre‐computed Eulerian fluid simulations. By operating in the vector potential space with projection‐free boundary handling, our method strictly preserves divergence‐free velocity fields without expensive global pressure solves.

A Maximal Concurrency and Low Latency Distributed Scheduling Protocol for Wireless Sensor Networks
International Journal of Distributed Sensor Networks, 2015 Existing work that schedules concurrent transmissions without collisions suffers from low channel utilization. We propose the Optimal Node Activation Multiple Access (ONAMA) protocol to achieve maximal channel spatial reuse through a distributed maximal ...

Medical Physics, Volume 53, Issue 5, May 2026.Abstract Background Treatment planning in radiotherapy is inherently a multi‐criteria optimization (MCO) problem, as it requires balancing competing clinical goals. Traditionally, the treatment's robustness is not formulated as a part of this decision making problem, but dealt with separately through margins or robust optimization.
