Objectives: This study investigates the differences between in-person versus virtual format of an advanced communication skills OSCE through thematic analyses of post-OSCE debrief transcripts.
Methods: Two cohorts of senior medical students participated in either a 2019 in-person or 2021 virtual advanced communication skills OSCE. Students were grouped in triads and rotated through three of five possible cases. Afterwards, students participated in a faculty-led debrief (in-person in 2019, virtual in 2021). Inductive thematic analysis was used to compare the themes and the ratio of comments related to the themes were compared between the virtual and in-person OSCEs.
Results: Thematic analyses for both in-person and virtual OSCEs identified the same four major themes (Case Review, Emotional Response, Feedback, and Reflection) and 11 subthemes. However, the ratio of comments related to Case Review was lower in the virtual OSCE compared to in-person < .0001). Analysis of subthemes within Case Review revealed the percentage of comments was higher for Content and lower for Challenges in the virtual OSCE compared to in-person (both < .0001). There were no differences in the ratios of comments related to Emotional Response, Feedback, and Reflection, or their subthemes.
Conclusion: A virtual advanced communications skills OSCE for medical students showed identical qualitative themes to that from a prior in-person OSCE. However, students in the virtual OSCE focused more on matter-of-fact discussions about case content and less about the challenges they experienced. The findings suggest that some medical students may struggle with experiential learning in the virtual format, and have difficulty accessing or practicing their reflective observation skills based on Kolb's learning theory. Differences may be attributable to the additional cognitive load in the virtual setting, inadequate structural safeguards, and/or other limitations of virtual communication.

The lunar soil samples returned by China's Chang'e-5 (CE-5) contain valuable information on geological evolutions on the Moon. Herein, by employing high-resolution time-of-flight secondary ion mass spectrometry (TOF-SIMS), five rock chip samples from the CE-5 lunar soil are characterized in-depth, which reveal micro-morphological and compositional features. From the elemental/molecular ion distribution images, minerals such as pyroxene, ilmenite, feldspar, K-rich glass, silica, and silicate minerals are identified, along with their occurrence states and distribution results.

Organoids-on-a-chip exhibit significant potential for advancing disease modeling, drug screening, and precision medicine, largely due to their capacity to facilitate interactions among organoids. However, the influence of chip design on these interactions remains poorly understood, primarily due to our limited knowledge of the mediators of communication and the complexity of interaction dynamics. This study demonstrates that analyzing albumin secretion from liver organoids within an organoids-on-a-chip system can provide a measure of the interaction intensity among organoids, offering valuable insights into how chip design influences these interactions.

Gesture recognition plays a significant role in human-machine interaction (HMI) system. This paper proposes a gesture-controlled reconfigurable metasurface system based on surface electromyography (sEMG) for real-time beam deflection and polarization conversion. By recognizing the sEMG signals of user gestures through a pre-trained convolutional neural network (CNN) model, the system dynamically modulates the metasurface, enabling precise control of the deflection direction and polarization state of electromagnetic waves.

The formed optical cavity mode intensively relies on the size and geometry of optical cavity. When the defect or impurity exists inside the cavity, the formed cavity mode will be destroyed. Here, we propose a metacavity consisting of arrays of linear-crossing metamaterials (LCMMs) with abnormal dispersion, where each LCMM offers both the directional propagation channel for all incident angles and the negative refraction across its neighboring LCMMs.

We present a continuative definition of topological charge to depict the polarization defects on any resonant diffraction orders in photonic crystal slab regardless they are radiative or evanescent. By using such a generalized definition, we investigate the origins and conservation of polarization defects across the whole Brillouin zone. We found that the mode crossings due to Brillouin zone folding contribute to the emergence of polarization defects in the entire Brillouin zone.
