Effects of partial silage replacement with corn stover pellets on the rumen microbiota and serum metabolome of breeding cows.

Introduction: Straw pellet ration replacing part of silage is of great significance for farmers to save farming costs and solve the lack of feed resources. A comprehensive analysis of rumen microbial and serum metabolite compositions is conducted to promote the development of the modern breeding cows-feeding industry.

Methods: In this study, 18 healthy 2-year-old Simmental breeding cows weighing 550 ± 20 kg were selected and randomly divided into two groups.

TNMpBC-NeoBCSS model: a breast cancer specific survival prediction model for triple-negative metaplastic breast carcinoma patients with neoadjuvant therapy.

The breast cancer specific survival (BCSS) benefits of Neoadjuvant therapy (NeoAT) for triple-negative metaplastic breast cancer (TNMpBC) was uncertain. This study aimed to develop a prediction model for assessing the BCSS for TNMpBC patients with NeoAT. The primary cohort of 1163 patients with TNMpBC, from which a nomogram was established based on the results of a LASSO regression analysis, was derived from multi-centers data in China and the SEER database.

The NeRF Signature: Codebook-Aided Watermarking for Neural Radiance Fields.

Neural Radiance Fields (NeRF) have been gaining attention as a significant form of 3D content representation. With the proliferation of NeRF-based creations, the need for copyright protection has emerged as a critical issue. Although some approaches have been proposed to embed digital watermarks into NeRF, they often neglect essential model-level considerations and incur substantial time overheads, resulting in reduced imperceptibility and robustness, along with user inconvenience.

Regulating Crystallization for Pure-Iodide 1.68 eV Bandgap Perovskite Solar Cells with a Fill Factor over 86.

Mixed halide wide-bandgap (WBG) perovskites, widely used as a top-cell absorber in tandem solar cells, exhibit severe photoinduced halide phase segregation. A feasible solution is to exploit pure-iodide WBG perovskites, essentially increasing Cs content instead of Br to achieve bandgap widening. However, the efficiency of pure-iodine WBG perovskite solar cells (PSCs) reported so far has been inferior to that of the typical mixed halide WBG PSCs due to complex nucleation and phase transition processes, leading to poor crystallization quality and a high density of defect states in pure-iodine WBG perovskites.

Impact of hypotonic hyponatremia on outcomes in patients undergoing transcatheter aortic valve replacement: a national inpatient sample.

Background: Transcatheter aortic valve replacement (TAVR) has emerged as a major therapeutic option for treating aortic stenosis. Hyponatremia is a common electrolyte disorder closely associated with adverse cardiovascular outcomes. However, large-scale studies investigating the impact of hypotonic hyponatremia on outcomes among TAVR patients are lacking.
