A Fast Dynamic Range Compression with Local Contrast Preservation Algorithm for Low Dynamic Range Image Enhancement [PDF]
, 2012 This paper presents a new fast dynamic range compression format with a local-contrast-preservation (FDRCLCP) algorithm to efficiently resolve low dynamic range (LDR) image enhancement problem for natural color images.

Epigenetic reprogramming of lineage switching in cancer
FEBS Letters, EarlyView.Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

High Dynamic Range Image (HDRI) Rendering
, 2005 This paper suggests a method known as High Dynamic Range Image (HDRI) to pre-visualise architectural elements in three-dimensional (3D) environment used by Computer Graphic Imaging (CGI) film-makers to integrate 3D models and characters into live action ...

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network
FEBS Letters, EarlyView.Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

High Dynamic Range Video Encoding Algorithm Design and Implementation
, 2007 現實生活中之可見亮度由 0cd/m2 至數千億 cd/m2 不等。以往在 影像採集設備上因為頻寬、儲存容量以及一般顯示器之顯示能力不足等因數考量下，只能以 8bit 對亮度作量化。其中在訊號轉換與量化失真所損失之資訊，在要求高傳真、高清晰度顯示設備之今天，為影像再往上提升之主要障礙。而在生醫影像、太空探勘等需要高傳真動態影像資訊之任務中，能夠進行高動態範圍影像擷取之設備，達到更少失真為該領域發展之重要因數。 可是高動態範圍影像擷取之技術，有著資料量極大，傳統方法沒辦 法相容處理和硬體設計困難等問題 ...

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

High Dynamic Range Images Using Exposure Metering
, 2007 在真實的世界裡，景色的亮度差異是非常大的。我們人眼可以同時觀察到很暗及很亮的影像，也就是人眼能適應較大的亮度差異；然而，現在的相機因為裝置結構上的限制，因此無法取得較大的動態範圍影像。所以我們的研究致力於如何取得高動態範圍的影像。 有學者提出利用不同曝光時間來重建出高動態範圍影像的方法。因此我們延伸他們的方法，提出了如何選擇曝光比較好的照片來建立高動態影像的照片。我們的方法主要是量測影像的曝光亮度，然後決定這張照片是否適合我們。使用我們的方法除了能減少時間來重建取得高動態範圍影像外 ...

, 2006 High dynamic range imaging produces images with a much greater range of light and color than conventional imaging. The effect is stunning, as great as the difference between black-and-white and color television.

Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...
