Wide-Angular Tolerance Optical Filter Design and Its Application to Green Pepper Segmentation.

The optical filter is critical in many applications requiring wide-angle imaging perception. However, the transmission curve of the typical optical filter will change at an oblique incident angle due to the optical path of the incident light change. In this study, we propose a wide-angular tolerance optical filter design method based on the transfer matrix method and automatic differentiation.

Color-Ratio Maps Enhanced Optical Filter Design and Its Application in Green Pepper Segmentation.

There is a growing demand for developing image sensor systems to aid fruit and vegetable harvesting, and crop growth prediction in precision agriculture. In this paper, we present an end-to-end optimization approach for the simultaneous design of optical filters and green pepper segmentation neural networks. Our optimization method modeled the optical filter as one learnable neural network layer and attached it to the subsequent camera spectral response (CSR) layer and segmentation neural network for green pepper segmentation.

Diagnosis and prediction of prognosis for Bickerstaff's brainstem encephalitis using auditory brainstem response: a case report.

Background: It is difficult to diagnose Bickerstaff's brainstem encephalitis (BBE) in the acute phase, and emergency physicians could diagnose BBE as an unknown cause of consciousness disturbance.

Case Presentation: A 75-year-old woman presented with dizziness and weakness in both arms 1 week after an upper respiratory infection. She experienced gradual worsening of consciousness, had dilated pupils and no light reflex.

Control of parathyroid function in patients with a short history of hemodialysis.

Secondary hyperparathyroidism (SHPT) is one of the serious complications in patients with chronic kidney disease. Parathyroid glands secrete parathyroid hormone (PTH), stimulated partly by hyperphosphatemia and hypocalcemia complicating chronic kidney disease (CKD). Use of a calcium-based phosphate binder might be sufficient to reduce serum PTH levels in mild SHPT, while the recent K/DOQI clinical guidelines recommended vitamin D therapy for dialysis patients with serum level of intact parathyroid hormone of 300 pg/mL or more.

Preparation of ultrapure dialysate in Japan--clinical usefulness and short-term future.

In 1994, the water quality standard of dialysate and substitution fluid for on-line HDF was established by the Kyushu Society for HDF. On the other hand, with the widespread use of high-flux membrane, reverse filtration and reverse diffusion became evident, and purification of the dialysate has become essential even for usual hemodialysis. By using ultrapure dialysate, new blood purification methods can be performed, such as internal filtration-enhanced hemodialysis, on-line HDF, and on-line HF.
