As a promising secondary battery system, lithium—sulfur (Li—S) batteries have attracted extensive attention due to their high energy density. However, the development of Li—S is hindered by detrimental shuttling soluble lithium polysulfides (LiPs) in traditional liquid electrolytes. In this work, we fabricate functional gel polymer electrolyte for batteries. This consists poly(vinylidene fluori...

This paper focuses on the problems of input-to-state stability (ISS) and stabilization for nonlinear impulsive positive systems (NIPS). Using max-separable ISS Lyapunov function method, a sufficient condition is given general NIPS. On that basis, criteria linear (LIPS) affine (ANIPS) are given. Through them, properties can be directly judged from algebraic differential characteristics systems. ...

Keratoacanthoma (KA) is a benign epithelial proliferative lesion which frequently occurs on the sun exposed areas of the skin. KA originates within the pilosebaceous apparatus of the skin and may be solitary or multiple. Solitary KA can be difficult to differentiate from squamous cell carcinoma (SCC) both clinically and microscopically. However, the clinical course of the lesion and its ability...

Mucoepidermoid carcinoma (MEC) is the most common malignant, locally-invasive tumour of the salivary glands, and accounts for approximately 35% of all malignancies of the major and minor salivary gland. Minor salivary glands are scattered in different areas of the oral cavity such as palate, retromolar area, floor of the mouth, buccal mucosa, lips and tongue. MECs of tongue base are not common....

Paediatric patients comprise a small proportion of the SARS-CoV-2 infected population. They usually present with mild symptoms, however them may require intensive care due to shock and multi-organ failure related Inflammatory Multisystem Syndrome temporally associated (PIMS-TS). This review article summarises oral mucosal lesions in children COVID-19 PIMS-TS. The most common sites affected are ...
