Although metal nanowires (NWs), such as silver NWs, are ideal materials for flexible transparent electromagnetic shielding films, the challenge of obtaining absorptive films with high transmittance and efficiency (SE) still exists. To address this issue, study used iron (Fe NWs) excellent microwave absorbing properties to construct structures ordered NW distributions. A series polyethylene terephthalate (PET)/Fe NWs/poly (3,4-ethylenedioxythiophene) (PEDOT) interference (EMI) were prepared...

This study proposes a lightweight convolutional neural network with an octave-like convolution mixed block, called OLCMNet, for detecting driver distraction under limited computational budget. The OLCM block uses point-wise (PC) to expand feature maps into two sets of branches. In the low-frequency branches, we perform average pooling, depth-wise (DC), and upsampling obtain low-resolution map, reducing spatial redundancy connection density. high-frequency expanded map original resolution is...
