Selective laser trabeculoplasty (SLT), used to treat glaucoma and ocular hypertension, requires the use of a gonioscope placed on the cornea to visualize and irradiate the trabecular meshwork (TM). Alternatively, non-contact direct SLT (DSLT) irradiates the TM through the overlying tissues. Here we analyze this innovative procedure using analytical modeling and Monte Carlo simulations to quantify the laser energy reaching the TM through the overlying tissues. Compared with energy launched from the laser, DSLT energy transmission to the TM is 2.8 times less than SLT, which verifies the efficacy of non-contact DSLT given the lowest reported effective SLT energies.

Bauhaus-University Weimar, Department of Building Physics, Coudraystrasse 11A, Weimar 99423, Germany.
This dataset presents the indoor air temperature collections using the novel technique of Acoustic travel time TOMography (ATOM) in the ultrasonic frequency range. The presented measuring system employs early reflections as sound propagation paths in addition to the travel time of the direct path, effectively combining room acoustics with tomography techniques. The data was collected across various measurement scenarios within the climate chamber laboratory at the Building Physics Department at the Bauhaus-University Weimar.

Article Synopsis
- Dinotefuran negatively impacts honeybee behavior, particularly their homing abilities, but the exact mechanisms are not fully understood.
- The study discovered that even without direct contact, dinotefuran can significantly alter the expression of MagR (a magnetoreceptor) in honeybees, leading to a reduced homing rate.
- The interaction between the MagR and Cry2 genes is crucial, as light is necessary for MagR to respond to magnetic fields, and reducing the expression of these genes further impairs the bees' navigation capabilities.

In elderly monitoring or indoor intrusion detection, the recognition of human activity is a key task. Owing to several strengths of Wi-Fi-based devices, including their non-contact and privacy protection, these devices have been widely applied in the area of smart homes. By the deep learning technique, numerous Wi-Fi-based activity recognition methods can realize satisfied recognitions, however, these methods may fail to recognize the activities of an unknown person without the learning process.
