StageACT: Stage-Conditioned Imitation for Robust Humanoid Door Opening
Humanoid robots promise to operate in everyday human environments without requiring modifications to the surroundings. Among the many skills needed, opening doors is essential, as doors are the most common gateways in built spaces and often limit where a robot can go. Door opening, however, poses unique challenges as it is a long-horizon task under partial observability, such as reasoning about the door's unobservable latch state that dictates whether the robot should rotate the handle or push …

Optimized Sparse Network Coverage via L1-norm Minimization
The selection of nodes that can serve as cluster heads, local sinks and gateways is a critical challenge in distributed sensor and communication networks. This paper presents a novel framework for identifying a minimal set of nexus nodes to ensure full network coverage while minimizing cost. By formulating the problem as a convex relaxation of the NP-hard set cover problem, we integrate the graph theoretic centrality measures of node degree and betweenness centrality into a cost function optimi…

Optimizing Spreading Factor Selection for Mobile LoRa Gateways Using Single-Channel Hardware
The deployment of mobile LoRa gateways using low-cost single-channel hardware presents a significant challenge in maintaining reliable communication due to the lack of dynamic configuration support. In traditional LoRaWAN networks, Adaptive Data Rate (ADR) mechanisms optimize communication parameters in real time. However, such features are typically supported only by expensive multi-channel gateways. This study proposes a cost-effective and energy-efficient solution by statically selecting the…

Gateways to Orbital and Spin Hall Effects in Rh-Doped Altermagnetic RuO$_2$
Ruthenium dioxide (RuO$_2$) has recently emerged as a prototypical material for exploring the fundamental properties of altermagnets. In this work, we investigate the impact of Rhodium (Rh) doping on the electronic and transport characteristics of altermagnetic RuO$_2$ using first-principles calculations. We show that Rh substitution at Ru sites modifies the spin-splitting of electronic bands across momentum space and reshapes the spin-resolved Fermi surface topology. These changes are found to…

Performance Evaluation of LoRa for IoT Applications in Non-Terrestrial Networks via ns-3
The integration of Internet of Things (IoT) and Non-Terrestrial Networks (NTNs) has emerged as a key paradigm to provide connectivity for sensors and actuators via satellite gateways in remote areas where terrestrial infrastructure is limited or unavailable. Among other Low-Power Wide-Area Network (LPWAN) technologies for IoT, Long Range (LoRa) holds great potential given its long range, energy efficiency, and flexibility. In this paper, we explore the feasibility and performance of LoRa to sup…
