Evolutionary optimisation of pixelated IFA inspired antennas.

As wireless communication systems increasingly require compact and efficient antennas, conventional antenna design methods are proving difficult to meet the rigorous demands of modern applications. For this purpose, this study introduces a methodology which uses pixelated Inverted-F Antenna (IFA) inspired designs optimised through genetic algorithms to enhance performance in constrained spatial environments. As pixels the antenna features the exemplary use of Einstein Hat-shaped tiles, enabling the antenna to efficiently utilize space.

A Rare Complication of Cannabinoid Hyperemesis Syndrome.

BACKGROUND Cognitive errors are common in medical practice and can have serious consequences for patients related to misdiagnosis and delays in diagnosis and treatment. We report a case in which cognitive error substantially influenced a patient's diagnosis and treatment. CASE REPORT This report recounts the case of an adolescent girl with symptoms similar to those of her previous episodes of tetrahydrocannabinol-induced hyperemesis, despite a 21-kg weight loss over 6 months.
