Published: July 2010

We present a novel low-coherence interferometer configuration, equipped in each arm with an adjustable optical path length ring. By compensating for the losses in the rings using semiconductor optical amplifiers, interference of low-coherence light after traversing the two rings 18 times is obtained. This configuration is employed to demonstrate simultaneous en face optical coherence tomography imaging at five different depths in a Drosophila melanogaster fly.

Purpose: Growth of macular neovascularization (MNV) associated with development of complete retinal pigment epithelial and outer retina atrophy (cRORA) been observed in eyes neovascular age-related macular degeneration (nAMD) under effective anti-vascular endothelial growth factor (VEGF) therapy. We aimed to evaluate the influence of the presence of MNV on the sensitivity of the overlaying retina both in patients with or without cRORA and to generate hypotheses about their association.

Methods: Pilot study on nAMD patients undergoing long-term anti-VEGF therapy that had also undergone microperimetry testing.

Battery-free head orientation measurement using passive RFID tags.

Department of Human Centered Design, Cornell University, Ithaca, NY, USA.

Real-time measurement of head rotation, a primary human body movement, offers potential advantages in rehabilitating head or neck motor disorders, promoting seamless human-robot interaction, and tracking the lateral glance of children with autism spectrum disorder for effective intervention. However, existing options such as cameras capturing the entire face or skin-attached sensors have limitations concerning privacy, safety, and/or usability. This research introduces a novel method that employs a battery-free RFID tag-based wearable sensor for monitoring head orientation, as a substitute for the existing options like camera.

Unlabelled: Face masks became a part of everyday life during the SARS-CoV-2 pandemic. Previous studies showed that the face cognition mechanism involves holistic face processing, and the absence of face features could lower the cognition ability. This is opposed to the experience during the pandemic, when people could correctly recognize faces, although the mask covered a part of the face.

EXPRESS: Individuals with developmental prosopagnosia tend to focus more evenly on facial features.

The causes of developmental prosopagnosia (DP) have long been a focus of research; however, the cause has not been conclusively identified. This study uses behavioral and eye movement techniques to explore the causes of DP by comparing differences in fixation patterns during face recognition between the DP and control groups. A mixed experimental design of 2 (group: control, DP) x 3 (area of interest (AOI): eyes, nose, mouth) was adopted, dividing faces into 3 AOIs: eyes, nose, and mouth.

Background: Diseases triggered by glucose and lipid metabolic disorders, such as hyperglycemia and hyperlipidemia, have become a global health threat. According to statistics, diabetic patients have exceeded 463 million worldwide, and the prevalence of hyperlipidemia is also continuously rising. These glycolipid metabolic diseases not only significantly increase the risk of complications such as cardiovascular disease, stroke, and kidney disease but also impose a huge economic burden on the global healthcare system.
