The rise of artificial intelligence is changing the shape of many different fields, and ophthalmic medicine is no exception. Convolutional neural networks (CNNs) have achieved remarkable results in the assisted diagnosis of ophthalmic diseases. However, they face challenges such as limited labeling and small dataset sizes. In recent years, self-supervised...

Background Electron accelerators are used in a number of applications, from medical imaging by x-ray production, to gamma-ray production for medical applications. Integrating high-power lasers and electron beams can potentially improve the performance of electron accelerators, make compact x-ray sources, and potentially create new kinds of light. However,...

When transmitting and receiving electromagnetic signals, there is a need to match the frequencies and the phases of both a received signal and a locally generated signal. In terms of signal to noise ratio (SNR), the alignment of the phases gives the best results for retrieving any data that is modulated on the received signal. Better SNR yields higher...

-collapse: collapse; } Rapid and economical detection of biomarkers and infectious agents present in biological fluids is vitally important for decision making in health care. In particular, diagnostic immunoassays based on antibody recognition have been established as very specific and powerful for a wide range of disease detection and biomarker...

Diagnosing and monitoring diseases and health often requires detecting and measuring concentrations of one or more analytes in a patient. Frequent trips to a healthcare facility are onerous and expensive and at home testing is painful, sometimes laborious and time consuming. All of this may lead to a lack of regular testing, and could mean missed diagnoses...

­Visually impaired individuals often rely on assistive devices that attempt to encode spatial information into other means such as audio or tactile signals. However, challenges in implementation and interpretation of spatial information still exist. For instance, many existing devices still provide limited information to a user that the user must...

­Often after an individual experiences a neurological event such as traumatic brain injury (TBI), cerebrovascular accident (CVA), multiple sclerosis (MS), stroke, etc., they suffer from a condition called midline shift syndrome (MSS). MSS causes those affected to lean their body away from the non-paralyzed side on a continual basis due to a change...

­Background Polyimide is used as a substrate for flexible electronics and flexible solar cells. The processing of polyimides has previously been challenging because of their low solubility in common solvents and their high softening temperature. De-bonded polyimide at a thickness of less than 30 microns is difficult to handle without creasing or...

Glucose, oxygen, and extracellular pH are important components of human metabolic processes -- many diseases are associated with glucose transport and metabolic disorders including diabetes and cancer. Monitoring glucose and cell metabolism can provide invaluable information for understanding these diseases. There are many assays and sensors for glucose,...

Glucose and oxygen are important components of human metabolic processes -- many diseases are associated with glucose transport and metabolic disorders including diabetes and cancer. Monitoring glucose and cell metabolism can provide invaluable information for understanding these diseases. There are many assays and sensors for both glucose and oxygen,...
