This paper investigates a novel robust wideband beamforming algorithm based on the frequency-difference (FD) technique. While FD technique can maintain good frequency invariance (FI) of the beamformer, it introduces cross terms that can adversely ...

Accurate detection of offensive language is crucial for maintaining harmony on social media platforms. However, the lack of well-annotated datasets makes it challenging to classify semantically Chinese offensive language using deep learning. To ...

The retention of audiences has become a pressing issue in the paradigm of livestreaming electronic commerce. Embracing the cognitive appraisal theory of emotions, this study develops a research model to gauge the relationship between emotion and ...

The emergence of 5G network slicing and computing offloading technology is expected to support Mobile Edge Computing (MEC) systems to reduce service delays while improving resource utilization, thereby better meeting the needs of different users. ...

Cloud computing improves server utilization and reduces the number of physical servers through virtualization technology, which directly reduces energy consumption and corresponding carbon emissions. The elastic scalability of cloud platforms allows ...

Tree-Seed optimization algorithm (TSA) has certain advantages in solving optimization problems, and the seed generation mechanism can ensure that the global optimal solution is recovered. However, the update method for the tree is a single process ...

Using a minimal but sufficient closed-loop encapsulation and the theoretical framework of classical control, we implement and test the mathematical model of the baroregulation due to Mauro Ursino [24]. We present and compare data from a local ...

The terrain in the southern plains of China is low and gentle, and the river network structure is complex. In order to quickly solve the problem of unclear impact of hydrodynamic regulation on the river network and facies in this area, this study takes ...

Livestreaming e-commerce (LSE) exhibits a noteworthy idiosyncrasy in the form of escalating instant order cancellations, wherein consumers swiftly revoke their purchases during livestreaming before receiving the products. This study leveraged the ...

• We investigate the factors influencing viewers' instant order cancellation behaviors.
• We found a significant impact of anchors' emotions on the arousal and valence of group emotions.
• We found the roles of anchor and group emotions ...

Gaze point estimation is an essential technology in extended reality devices, and plays a vital role in the metaverse with consumer health. A challenging issue is the great variation underlying the gaze-related encode information, which makes current ...

Simple cycle reservoir is a classic work in reservoir structure design, and has good performance in tasks such as discrete dynamical system prediction and time series classification. However, the overly simple reservoir structure weakens its ...

The astounding success made by artificial intelligence in healthcare and other fields proves that it can achieve human-like performance. However, success always comes with challenges. Deep learning algorithms are data dependent and require large datasets ...

To explicitly exploit the collaborative signals in the user-item interaction graph, a growing number of recent Collaborative Filtering (CF) studies adopt Graph Convolution Network (GCN) as a basis. Though effective, these methods ...

In this article, we propose two direction-of-arrival (DOA) estimation methods to further improve the resolution and performance of subspace-based algorithms. While most subspace-based algorithms employ either noise or signal subspaces, we utilize ...

• An initial DOA estimation algorithm based on projection vector element multiplication is proposed to further improve the resolution.
• Two improved algorithms are proposed to address the problem of pseudo peaks, and balance the ...

Gaze estimation typically involves determining the direction or point of gaze based on a single image of the eye or face. However, due to variations in the internal structure and morphology of eyes among individuals, existing models for gaze estimation ...

• This study explored the diffusion mechanism that affects the behavior intention of social commerce from key characteristics (trust and platform innovation characteristics) and social influence in different stages.
• Findings show that ...

Social commerce is a relatively new e-commerce model that has the potential to drive consumption growth and promote flexible social employment. However, despite its potential benefits, studies have shown that customers still tend to more heavily ...

Reconstructing the interference-plus-noise covariance matrix (INCM) is popular in the field of adaptive beamforming. In this paper, two novel methods are proposed to improve the performance of the adaptive beamformer. First, the noise power is estimated ...

The majority of the existing adaptive beamforming methods utilize the interference-plus-noise covariance matrix (INCM) to prevent the signal of interest (SOI) from being suppressed. However, the removal of the SOI component will lead to a ...

Reconfigurable intelligent surface (RIS), a planar metasurface consisting of a large number of low-cost reflecting elements, has received much attention due to its ability to improve both the spectrum and energy efficiency (EE) by ...

Heart sound analysis plays an important role in early detecting heart disease. However, manual detection requires doctors with extensive clinical experience, which increases uncertainty for the task, especially in medically underdeveloped areas. This ...
