Pretraining GPT-style models in Hungarian
In this paper, we introduce two bilingual large language models, named OTP-1.5B and OTP-13B, designed with a focus on both English and Hungarian languages. Both models utilize an 8k token context window and are trained on a dataset of 640 billion tokens, allowing the models to capture a broad range of linguistic nuances and generalize effectively across languages. Notably, their performance in Hungarian is on par with the results reported for equivalent models in English, such as GPT-3, marking a significant breakthrough in bilingual model development and evaluation. This achievement demonstrates the viability of scaling language models to perform robustly in lessresourced languages like Hungarian, a critical advancement for linguistic diversity in AI research. In addition, we introduce new benchmark datasets specifically designed to evaluate Hungarian language capabilities, addressing a significant gap in the current landscape of multilingual large language model (LLM) assessment. These benchmarks offer a comprehensive framework for measuring performance in non-English contexts, enabling more precise and culturally relevant evaluations of LLMs. Our models achieve state-of-the-art results in Hungarian, underscoring their proficiency and utility for a wide range of applications in both English and Hungarian language tasks.

Broadside Gain Enhancement of Wideband Monopole Circular Shaped Antenna Using FSS for Sub-6 GHz Applications
This paper introduces a wideband circular patch antenna designed with a frequency selective surface (FSS) for sub-6 GHz applications. The proposed antenna features a monopole circular-shaped patch with a partial ground plane, delivering an omnidirectional radiation pattern in the azimuth plane, resulting in relatively uniform gain in all directions. An FSS metamaterial enhances the antenna's gain and improves the broadside radiation pattern. The design incorporates three inner circular patches connected to the main patch. The FSS utilizes hybrid square/circle loop-based unit cells. The antenna and FSS are simulated using CST software and subsequently fabricated on an FR-4 substrate. The measured results demon strate an impedance bandwidth of 1.6 GHz with a peak gain of 5.4 dB at 3.5 GHz. The omnidirectional radiation pattern is converted into a directional one by placing a reflector FSS as a bottom substrate layer. The overall structure size is compact, measuring (0.34λ0 × 0.27λ0 × 0.016λ0), where λ0 is the free space wavelength corresponding to the lowest resonant fre quency within the operational bandwidth. This design achieves significant antenna size reduction and is well-suited for future sub-6 GHz applications.

Distributed Edge Computing Aided Environmental Severity Monitoring for Power Grid Equipment in Nakagami-m Fading Channels
This study explores the concept of multiuser mobile edge computing (MEC) networks aided environmental severity monitoring for power grid equipment, where an MEC server facilitates the computation of tasks from N users via wireless transmission in the presence of Nakagami-m fading channels. To analyze the system performance, we first define the system outage probability based on energy consumption, where the outage event is triggered when the energy required to complete the users’ tasks exceeds a specified threshold. We then develop an analytical expression for the system outage probability in Nakagami-m fading channels and provide a high signal-to-noise ratio (SNR) asymptotic analysis. Additionally, we optimize the system performance by adjusting the task offloading ratios. Finally, simulation and numerical results in Nakagami-m fading channels validate the proposed methods. The results show that the performance of multiuser MEC networks can be improved by increasing the bandwidth or energy consumption threshold for environmental severity monitoring in power grid equipments.
