The impact of epigenetic and epitranscriptomic modifications on Alzheimer's disease: the mysteries of DNA, RNA, and histone methylation.

AD (Alzheimer's disease) is a neurodegenerative disorder of the CNS (Central Nervous System) characterized by progressive memory decline, significantly impairing patients' quality of life and representing the most common cause of dementia. However, the exact etiology of AD remains unclear and is likely influenced by the interplay of genetic, lifestyle, and environmental factors. Therefore, extensive research efforts are urgently needed to unravel the complex mechanisms underlying the onset and progression of AD.

Mushroom image classification and recognition based on improved ConvNeXt V2.

Using on-site images to classify and identify wild mushroom species is the most effective way to prevent incidents of harm caused by eating wild mushrooms. However, the complexity of natural scenes and the similarity of mushroom morphology bring challenges for accurate classification and recognition. To this end, this paper proposes an improved ConvNeXt V2 network model for classification and recognition of mushrooms in complex scenes and similar appearances.

The role of Anderson's rule in determining electronic, optical and transport properties of transition metal dichalcogenide heterostructures.

Two-dimensional (2D) transition metal dichalcogenides (TMDs) MX2 (M = Mo, W; X = S, Se, Te) possess unique properties and novel applications in optoelectronics, valleytronics and quantum computation. In this work, we performed first-principles calculations to investigate the electronic, optical and transport properties of the van der Waals (vdW) stacked MX2 heterostructures formed by two individual MX2 monolayers. We found that the so-called Anderson's rule can effectively classify the band structures of heterostructures into three types: straddling, staggered and broken gap.

A comparison of food habits and prey preferences of Amur tiger (Panthera tigris altaica) at the southwest Primorskii Krai in Russia and Hunchun in China.

A small, isolated Amur tiger population ranges across the southwest Primorskii Krai region in Russia and Hunchun region in China. Many individuals, with "dual nationality," cross the border frequently. Formulating effective conservation strategies requires a clear understanding of tiger food requirements in both countries.
