As is well known the novel coronavirus (COVID-19) is a zoonotic virus and our model is concerned with the effect of the zoonotic source of the coronavirus during the outbreak in China. We present a SEIS complex network epidemic model for the novel coronavirus. Our model is presented in fractional form and with varying population. The steady states and the basic reproductive number are calculated. We also present some numerical examples and the sensitivity analysis of the basic reproductive number for the parameters.

Hyperspectral images are rich in spectral and spatial information, providing a detailed and comprehensive description of objects, which makes hyperspectral image analysis technology essential in intelligent agriculture. With various corn seed varieties exhibiting significant internal structural differences, accurate classification is crucial for planting, monitoring, and consumption. However, due to the large volume and complex features of hyperspectral corn image data, existing methods often fall short in feature extraction and utilization, leading to low classification accuracy.

Objectives: Two different European Reference Networks cover CTDs with paediatric onset, the European Reference Network on Rare and Complex Connective Tissue Diseases (ERN ReCONNET) and the European Reference Network on Rare Immunological Disorders (ERN RITA). The transition of care is a significant focus, with ReCONNET centres actively addressing this through updated programs. Despite these efforts, challenges persist.

Globally, youth mental health services are evolving, with Australia's services presented as a leading exemplar. services were designed as enhanced primary care-based entities and were expected to collaborate with local acute, and specialist clinical and psychosocial services. The lack of large-scale health services trials necessitates understanding their impact through systematic monitoring and evaluation.

Introduction: Inflammatory bowel diseases (IBDs), comprised of ulcerative colitis (UC) and Crohn's disease (CD), are chronic inflammatory diseases of the gastrointestinal tract. Clinicians and patients must vigilantly manage these complex diseases over the course of the patient's lifetime to mitigate risks of the disease, surgical complications, progression to neoplasia, and complications from medical or surgical therapies. Over the past several decades, the armamentarium of IBD therapeutics has expanded; now with biologics and advanced small molecules complementing conventional drugs such as aminosalicylates, corticosteroids and thiopurines.
