Buzz, squeak and rattle (BSR) noise has become apparent in vehicles due to the significant reductions in engine noise and road noise.The BSR often occurs in driving condition with many interference signals.Thus, the automatic BSR detection remains a challenge for vehicle engineers.In this paper, a rattle signal denoising and enhancing method is pro
Dental biofilms are highly assembled microbial communities surrounded by an extracellular matrix, which protects the resident microbes.The microbes, including commensal bacteria and opportunistic pathogens, coexist with each other to maintain relative balance under healthy conditions.However, under hostile conditions such as sugar intake and animat
Bacterial cellulose (BC) is a biopolymer synthesized by certain acetic acid bacteria strains.The safety of BC regarding its potential use in food applications is here reviewed.The acute, sub-acute and subchronic oral animationbengal.com toxicity assays showed that consumption of BC had no adverse effects in rats.Several studies demonstrated that BC
Many controversies in medical science can be framed as tension between a coherence approach (which seeks logic and explanation) and a correspondence approach (which emphasizes empirical correctness).In many instances, a coherence-based theory leads to an understanding of disease that is not supported by empirical evidence.Physicians here and patien
