An extension of shape-adaptive DCT (SA-DCT) towards DC separation and Delta DC correction
, 2022 S.647-652In the framework of the ongoing MPEG-4 standardization phase of ISO/IEC Sikora and Makai suggested a shape-adaptive DCT algorithm (SA-DCT) for efficient and low-complexity coding of arbitrarily shaped video objects. Referring to this algorithmic

Advanced Science, EarlyView.Multi‐trait genome‐wide association mapping identifies a central hub regulator, COLD AND CATECHINS REGULATOR 1 (CCR1), and its excellent natural allele variation, coordinately enhancing cold tolerance and promoting catechins biosyntheis. CsCCR1 interacts with CsCBF1/3 and is transcriptionally activated by CsLUX and CsKUA1 to promote catechins ...

Arbitrary-ratio image resizing using fast DCT of composite length for DCT based transcoder
, 2006 We propose a fast arbitrary-ratio image resizing method for transcoding of the compressed images. The downsizing process in the discrete cosine transform (DCT) domain can be implemented by truncating high-frequency coefficients, whereas the upsizing ...

From Materials to Systems: Challenges and Solutions for Fast‐Charge/Discharge Na‐Ion Batteries
Advanced Energy Materials, EarlyView.This review systematically analyzes the key characteristics limiting the fast‐charge/discharge capability of Na‐ion batteries (SIBs) from a multi‐scale perspective encompassing electrode materials, the electrode‐electrolyte interface, and the system. Furthermore, it presents practical solution strategies for the fundamental issues arising at each scale,

Angewandte Chemie, EarlyView.The carbocyclic Decitabine analog (cAzadC) incorporates as an antimetabolite weakly into the genome of growing tumor cells, where it triggers a genome‐wide demethylation and a surprisingly strong hydroxymethylation of cytosine, which translates into an efficient in vivo antitumor (AML) effect.

, 2013 (A). rDPSCs expressing CaV1.2 were probed with anti- CaV1.2 (upper gel) or anti-DCT (middle gel) using western blotting. Anti-DCT recognizes a 75kD short cleavage product that corresponds to the C-terminal fragment of CaV1.2.

Modulation of Local Environment for Selective Bicarbonate Conversion to Multi‐Carbon Products
Advanced Energy Materials, EarlyView.Highly porous Cu electrode partially coated with an ionomer/carbon composite enables efficient conversion of bicarbonate to multi‐carbon products. By regulating the local reaction microenvironment, this strategy overcomes selectivity and reaction‐rate limitations, achieving Faradaic efficiencies of 43% for ethylene and 60% for total multi‐carbon ...

DCT sign-based robust image hashing
, 2013 This paper proposes a robust image hashing technique based on the sign of coefficients in the Discrete Cosine Transforms (DCT) domain. The idea consists of exploiting the energy compaction property of the DCT and its ability to carry information of edges

Advanced Intelligent Systems, EarlyView.We present a novel AI‐integrated implantation‐on‐chip platform that enables mimicking and monitoring the maternal–fetal interactions at the early phases of human embryo implantation with high spatiotemporal resolution. The complexity of the trophoblast invasion process was addressed by conducting the analysis at global (rate of invasion) and local ...

Invertible Integer DCT Algorithms
, 2007 Integer DCTs have important applications in lossless coding. In this paper, an integer DCT of radix-2 length n is understood to be a nonlinear, (left-)invertible mapping which acts on Z^n and approximates the classical discrete cosine transform (DCT) of ...
