This paper introduces CONV_GBERT, a hybrid deep learning framework for robust sentiment classification. The model integrates the bidirectional contextual understanding of BERT, the generative capabilities of GPT, and the...

Introduction. The stability of grid-connected inverters is critical for the integration of renewable energy into modern power systems. However, this stability is significantly challenged under weak grid conditions, chara...

Electrochemical potential noise signals from LiFePO4 batteries often contain a slowly varying trend component that overlaps with and distorts the intrinsic low-frequency electrochemical noise. This component must therefo...

INFN-CHNet is the cultural heritage network of the Italian National Institute of Nuclear Physics (INFN) and is constituted by units from Italy and from outside Europe, one of them at Universidad Nacional de San Martín (...

Abstract A methodology based on spectral analysis for localization of multiple partial discharges in dielectric region of hydro-generator coils is proposed. This pinpointing of multiple discharges aims to provide means f...

Efficient current control in boost converters is critical for electric vehicle (EV) battery charging applications, where dynamic operating conditions challenge conventional control strategies. This paper presents a novel...

It is well known that pituitary TSH exerts the major task in the regulation of thyroid function. However, this gland is capable of certain degree of autonomy, independently of TSH control. Iodine plays an important role ...

Abstract Background Soil salinization severely restricts the growth and forage yield of Medicago sativa (alfalfa), a globally critical leguminous forage crop, yet the regulatory mechanisms governing its salt tolerance re...

Abstract Background Collagenous fibroma (CF), also known as desmoplastic fibroblastoma, is a rare benign fibroblastic/myofibroblastic tumor characterized by FOSL1/FOS rearrangements. CF typically presents as a solitary, ...

Abstract Background The tumour microenvironment and systemic inflammatory environment are related to the diagnosis, treatment and prognosis of various tumours. This study aimed to evaluate the clinicopathological signifi...

OBJETIVO: verificar se, no escrutínio de rotina, fatores relacionados com a adequabilidade da amostra, padrão celular e critérios citomorfológicos estão associados a resultados falso-negativos (FN) dos exames citopa...

Plants frequently encounter diverse abiotic stresses, which require precise transcriptional regulation to maintain basic survival plasticity. The BES1 transcription factor family, a key component of brassinosteroid (BR) ...

BackgroundIntegrated single-cell morpho-molecular analysis is vital for precision pathology, yet accurate nuclear instance segmentation from standard histopathology images remains challenging due to staining variability ...

Abstract To access the effect of SIRT1 in cerebral infarction and to explore its mechanism of ferroptosis. Bioinformatic Analysis was used to discover the associations between Ferroptosis-Related Genes and Cerebral Infar...

The IKAROS family of zinc finger transcription factors (IKZF1–4) plays a central role in lymphocyte development and immune regulation. Pathogenic IKZF1 variants produce a wide phenotypic spectrum related to whether the...

The effect of gravity on the dynamics of flow boiling channels is studied using linear and non-linear stability analysis tools. The developed tools are used to predict experimental results showing good agreement. The lin...

Aims. Bars are considered an efficient mechanism for transporting gas toward the central regions of galaxies and potentially enhance nuclear activity. However, the extent to which bars influence active galactic nuclei (A...

Dichroplus elongatus is an extensively distributed South American grasshopper considered a pest of major crops. Argentinean populations show a widespread B-chromosome polymorphism which could be maintained as the result ...

Three-phase pulse width modulation (PWM) rectifiers are crucial in industrial, civil, and transportation applications. Due to the diversity of grid loads, the three-phase input voltage may be unbalanced, which consequent...

Abstract This article presents the analysis of a hybrid, error correction-based, neural network model to predict the path loss for suburban areas at 800 MHz and 2600 MHz, obtained by combining empirical propagation model...

Abstract This paper presents a radiopropagation algorithm based on a Ray Tracing (RT) technique that combines a modified multipath model for constant refractivity gradient profiles and the Uniform Theory of Diffraction (...

Abstract This paper describes an investigation of the possibility of using a new conductive ink, insted of copper clad laminates, in the manufacturing of microstrip patch antennas on glass and fiberglass substrates and o...

Abstract In this article an innovative method of studying and removing the resonances, inherently exhibit by some waveguide to microstrip transitions, is presented. By modeling an equivalent circuit, this new approach al...

Abstract This paper originates from a practical experiment based on Mesh Networks. The promising results obtained from this experiment prompted us to discuss in greater depth whether Wireless Local Area Networks (WLAN) a...
