Heart rate variability (HRV), systolic period variability (SPV), and diastolic period variability (DPV) have shown potential for assessing cardiac function.It is unknown whether the time delay between the myocardial electrical and mechanical activities (i.e., electromechanical delay, EMD) also possesses variability, and if it does, whether this EMD

This paper introduces a novel technique to enhance the gain of the TEXTURIZING SPRAY basic monopole antenna by using broadband gradient refractive index (GRIN) metamaterial.The proposed GRIN is designed by using a parallel-line unit cell metamaterial with different refractive index.A seven GRIN lens is placed on the omnidirectional printed basic mo

Sustainable food production to feed the growing population in Africa remains Frozen Beverage Dispensers:Frozen Drink a major challenge.Africa has 64% of the global arable land but produces less than 10% of its food locally due to its inherently low soil nutrient concentrations.Poor soil fertility and a lack of fertilizer use are the major constrain

IntroductionNutritional deficiency occurs frequently during pregnancy and breastfeeding.Tryptophan (Trp), an essential amino acid which is critical for protein synthesis, serves as the precursor for serotonin, melatonin, and kynurenine (Kyn).The imbalance between serotonin and kynurenine pathways in Trp metabolism is closely related to inflammation

Normal mode separation and information extraction are popular topics in marine acoustics.The extraction of modal wavenumbers and modal depth functions using the data of a vertical line array is beneficial to various applications.In this paper, we systematically introduce a normal mode separation method based on the consistency restraint of the hori
