In recent years, there are many surrogates for tensor tubal rank. In this paper, we propose a hybrid norm consisting of the weighted nuclear norm and the weighted Frobenius norm (WTNFN) of a tensor. The WTNFN is a surrogate for tensor tubal rank, and studies the weighted tensor nuclear and Frobenius norm minimization (WTNFNM) problem. The aim is to enhance the stability of the solution and improve the shortcomings of the traditional method of minimizing approximate rank functions based on the te...

In modern times, many scholars have studied the origin of Tianjin dialect and its relationship with Guzhen dialect in Anhui Province. However, through reading literature, it can be seen that the research on the neutral tone of Guzhen dialect has not been carried out. Therefore, based on previous studies, this paper intends to summarize the distribution of the neutral tone in Guzhen dialect through field and online surveys, recording and sorting out the results, and investigate the pitch value of...

Antisynthetase syndrome (AS) is a rare systemic autoimmune disease characterized by the presence of anti-tRNA synthetase antibodies. Cardiac involvement (pericarditis) in AS is uncommon. Here, we present the case of a young African female who presented with acute pericarditis as an initial manifestation of AS. She was diagnosed with anti-Jo1 antisynthetase syndrome based on Connors criteria. Treatment with corticosteroids and azathioprine improved symptoms. This case underlines the importance fo...

Research indicates that students with a high level of Grit and self-efficacy have higher levels of academic achievement. Grit is comprised of passion (consistency of interest) and perseverance of effort, for long-term goals. The purpose of this model is to increase Grit among underrepresented groups. It utilizes one aspect of self-efficacy, “vicarious experiences”, to increase STEM (Science, Technology, Engineering and Mathematics) Grit among underrepresented groups. Historical contributions fro...

Mucoepidermoid carcinoma is a malignant tumor that affects the salivary glands, particularly the parotid gland. Involvement of the accessory salivary glands is rarer; some cases have been described in the literature. The clinical symptoms are atypical with a slow and silent evolution which delays the diagnosis. The diagnosis is based on clinical, radiological and anatomopathological examination of diagnostic and prognostic interest. The management is essentially surgical with carcinological marg...
