Article Synopsis
  • - The article discusses a 28 GHz MIMO antenna design featuring a non-angular, planar dipole array that aims to enhance isolation using a metasurface technique.
  • - Initially, the design is a single-element antenna that evolves into a three-element structure to increase channel capacity, exciting multiple resonance modes (J1, J2, J3).
  • - The proposed antenna achieves a bandwidth of 26.7 to 29.6 GHz, with over 21 dB isolation improvement and a gain of 6.3 dBi, validated through various diversity performance metrics.

Introduction Maladaptive eating behaviors are emerging as the most significant determinants of obesity with a promising role in intervention. In the absence of a standardized tool to assess eating variations, an Eating Error Score (EES) tool was devised which comprised five zones for evaluating the severity of obesogenic behaviors as well as the specific area(s) with the highest susceptibility. This pilot study was aimed at evaluating the effectiveness of the EES in quantitating the eating behavior errors associated with excess weight and identifying the most affected zones.

Background: The Carotid Intima-Media Thickness (CIMT) is a simple and an inexpensive tool which can be used to assess the cumulative effect of atherosclerotic risk factors and it is also an independent predictor of the future cardiovascular risk. Nevertheless, criticism has been raised throughout the scientific community, based on the observations which indicated a weak correlation between CIMT and coronary atherosclerosis. It has been suggested by the International Atherosclerosis Project, that the atherosclerotic process occurs at the same time in the carotid, cerebral and the coronary arteries.
