This paper presents a novel shared-aperture smartphone antenna for sub-6 GHz and millimeter-wave (mmWave) bands.The proposed antenna module comprises a four-element mmWave patch antenna array integrated into a wideband sub-6 GHz slot antenna.The mmWave antenna covers the frequency band 26.5–29.5 GHz with isolation over 16 dB, and the sub-6 G
Living cells often need to measure chemical concentrations that vary in time, yet how accurately they can do so is poorly understood.Here, we present a theory that fully specifies, without any adjustable parameters, the optimal design of a canonical sensing system in terms of two elementary design principles: (1) there Radar Sensor exists an optima
Background and Objectives: Irritable bowel syndrome (IBS) is a chronic intestinal disorder, which is characterized by irritating pain during defecation or alteration of the bowel habits.In the curent study, the association of dietary glycemic index (GI) and glycemic load (GL) with the risk of this syndrome, was investigated in a large population of
An investigation has been made to predict the effects of forebody and afterbody shapes on the aerodynamic characteristics of several projectile bodies at supersonic speeds using analytical methods combined with semi-empirical design curves.The considered projectile bodies had a length-to-diameter ratio of 6.67 and included three variations of foreb
