Bacterial infections have a substantial impact on global health and can become serious if misdiagnosed with several diseases related to the central nervous, cardiovascular, and respiratory systems. The prognosis in patients with infectious disease strongly depends on early diagnosis and appropriate antibiotic therapy. We aimed to compare the accuracy of genus and species-level identification bacteria using biochemical testing and 16S rRNA sequence analysis.

This study shows that when compression/bending and torsion are applied simultaneously, the bond between the concrete core and steel tube may weaken, leading to slippage, which in turn reduces the structural system’s load-bearing efficiency.

This paper aims to develop an effective method for reduction and decomposition on large matrices with low required computational resources and fast processing times. Our contribution is to design a PCA-SVD hybrid method that dividesthe feature extraction into two phases: PCA-based size reduction and SVD-based decomposition. In our method, PCA is first applied to a large matrix to extract its important components

This paper deals with synchronization analysis problem for a class of fractional-order neural networks with unbounded delays. Using the Lyapunov function method combined with fractional Halanay inequality, we derive a novel sufficient condition for asymptotic stability of the error system resulting in two neural networks are synchronized.
