Hypoparathyroidism, deafness, and renal dysplasia (HDR) syndrome is a rare condition inherited as autosomal dominant trait and characterized by hypoparathyroidism, sensorineural deafness, and renal dysplasia. HDR syndrome is caused by haploinsufficiency of the GATA3 gene located on chromosome 10p15. Here, we report the case of a 32-day-old Korean male with HDR syndrome. He was presented due to ...

High Dynamic Range (HDR) signals fundamentally differ from the traditional low dynamic range (LDR) ones in that pixels are related (proportional) to the physical luminance in the scene (i.e. scenereferred). For that reason, the existing LDR video quality measurement methods may not be directly used for assessing quality in HDR videos. To address that, we present an objective HDR video quality m...

New imaging and rendering systems commonly use physically accurate lighting information in the form of highdynamic range (HDR) images and video. HDR images contain actual colorimetric or physical values, which can span 14 orders of magnitude, instead of 8-bit renderings, found in standard images. The additional precision and quality retained in HDR visual data is necessary to display images on ...

We and others recently demonstrated that the readily programmable CRISPR/Cas9 system can be used to edit the Drosophila genome. However, most applications to date have relied on aberrant DNA repair to stochastically generate frameshifting indels and adoption has been limited by a lack of tools for efficient identification of targeted events. Here we report optimized tools and techniques for exp...

A number of High Dynamic Range (HDR) video compression algorithms proposed to date have either been developed in isolation or only-partially compared with each other. Previous evaluations were conducted using quality assessment error metrics, which for the most part were developed for qualitative assessment of Low Dynamic Range (LDR) videos. This paper presents a comprehensive objective and sub...

The aim of the present study was to evaluate the results of hypofractionated accelerated CT-guided interstitial HDR-BRT using 2.5 Gy per fraction. From December 2008 to March 2010, 30 patients were treated for recurrence of previously-irradiated head and neck cancer. Thirteen patients underwent surgical resection followed by HDR-BRT to the tumour bed. Seventeen patients were treated with HDR-BR...

PURPOSE The aim of this study was to evaluate the feasibility of applying the high dynamic range (HDR) technique to radiographic imaging to expand the dynamic range of conventional radiographic images using a colored multiexposure approach. MATERIAL AND METHODS An appropriate study object was repeatedly imaged using a range of different imaging parameters using a standard clinical x-ray unit....

In this paper, we propose an adaptive perceptual quantization method to convert the representation of High Dynamic Range (HDR) content from the floating point data type to integer, which is compatible with the current image/video coding and display systems. The proposed method considers the luminance distribution of the HDR content, as well as the detectable contrast threshold of the Human Visu...

The voice Krlang capacity is analyzed ID a imiliiaotenna combined voice-data CDMA Reverse Link (RL). The influence of two different spatial combining techniques: Optimal Combining (OC) and Maximal Ratio Combining (MRO) on the voice Erlangs is evaluated when a single scheduled High Data Rate (HDR) data channel is shared by users desiring HDR services. The impact of randomly arriving data users o...

I present a revised approach to flash-exposure high dynamic range (HDR) imaging and demonstrate two applications of this image representation. The first application enables the creation of realistic ‘virtual photographs’ for arbitrary flash-exposure settings, based on a single flash-exposure HDR image. The second application is a novel tone mapping operator for flash-exposure HDR images based o...
