By analyzing the circular pattern, you can identify that Option D is most similar to the previous shapes. Option A has a different design, while Option B deviates from the sequence.

The advent of 2D materials heralds a new era of material capabilities and innovation potential. However, achieving a sustainable, circular 2D materials economy remains a multifaceted grand challenge ...

Abstract: We propose an analytical design procedure for a Gaussian-shaped circular band-pass 2D FIR filter and also a novel, efficient implementation of the designed filter based on a polyphase ...

The flow is studied as a dynamical system, so the present investigation is motivated by the presence of complex patterns, ... The 2D numerical simulations were ... Engineering, Via di Vallerano 139, ...
