Investigating the neural mechanisms of recreational role-playing associated with the reduction of subclinical anxiety by Wong, Jason Kang Chiang

“…This study thus sought to investigate the neural activations associated with recreational role-playing and subclinical anxiety, and if the former provided therapeutic benefits. 30 dyads were recruited to participate in four within-subjects conditions: (i) baseline, (ii) natural conversation, (iii) simple role-play, (iv) and role-reversal. Functional near-infrared spectroscopy was used to examine brain activity. …”

Giant photonic spin Hall effect empowered by polarization-dependent quasibound states in the continuum in compound grating waveguide structures by Wu, Feng, Liu, Tingting, Long, Yang, Xiao, Shuyuan, Chen, Gengyan

“…In this paper, we theoretically propose a polarization-dependent bound state in the continuum (BIC) in a compound grating waveguide structure based on the selectable guided resonance at near-infrared wavelengths. Empowered by the unique resonant property and polarization-dependent property of the quasi-BIC, the transverse shift of the PSHE can be intensively enhanced to the order of hundreds of micrometers. …”

Coherent energy scale revealed by ultrafast dynamics of UX3 (X = Al, Sn, Ga) single crystals by Nair, Saritha K., Zhu, J. X., Sarrao, J. L., Taylor, Antoinette J., Chia, Elbert E. M.

“…For UGa3, our data are consistent with the formation of a spin density wave gap as evidenced from the quasidivergence of the relaxation time τ near the Néel temperature TN. For UAl3 and USn3, the relaxation dynamics shows a change from single-exponential to two-exponential behavior below a particular temperature, suggestive of coherence formation of the 5f electrons with the conduction band electrons. …”

Self-Assembly of Semiconducting Polymer Amphiphiles for In Vivo Photoacoustic Imaging by Xie, Chen, Zhen, Xu, Lei, Qunli, Ni, Ran, Pu, Kanyi

“…Despite the advantages of semiconducting polymer nanoparticles (SPNs) over other inorganic nanoparticles for photoacoustic (PA) imaging, their synthetic method is generally limited to nanoprecipitation, which is likely to cause the issue of nanoparticle dissociation. The synthesis of near-infrared (NIR) absorbing semiconducting polymer amphiphiles (SPAs) that can spontaneously self-assemble into homogeneous nanoparticles for in vivo PA imaging is reported. …”
