Porous Organic Cages as Building Blocks for Framework Materials
Angewandte Chemie International Edition, Accepted Article.Confined nanospaces play a fundamental role in nature, inspiring synthetic analogues that emulate biological precision and efficiency. Among these, porous crystalline materials such as covalent organic frameworks (COFs), metal‐organic frameworks (MOFs), and molecular cage compounds have emerged as powerful platforms for catalysis, separation, and ...

Animal Research and One Health, EarlyView.The graphical abstract shows the principal results of this study. Eight major aroma‐contributing compounds (nonanal, octanal, dimethyl tetrasulfide, hexanal, 1‐octen‐3‐ol, (E)‐2‐nonenal, heptanal, and (E,E)‐2,4‐decadienal) were identified by electronic nose and GC‐O‐MS analysis, and their content increased with age.

Cross-Layer Optimization of DVB-T2 System for Mobile Services
International Journal of Digital Multimedia Broadcasting, 2010 Mobile broadcast services have experienced a strong boost in recent years through the standardization of several mobile broadcast systems such as DVB-H, ATSC-M/H, DMB-T/H, and CMMB. However, steady need for higher quality services is projected to surpass

, 2012 Digital Video Broadcasting (DVB) is a set of standards for digital television. DVB supports the encryption of a transmission using the Common Scrambling Algorithm (DVB-CSA). This is commonly used for PayTV or for other conditional access scenarios. While DVB-CSA support 64 bit keys, many stations use only 48 bits of entropy for the key and 16 bits are ...

LDPC decoder architecture for DVB-S2 and DVB-S2X standards [PDF]
2015 IEEE Workshop on Signal Processing Systems (SiPS), 2015 A particular type of conflict due to multiple-diagonal sub-matrices in the DVB-S2 parity-check matrices is known to complicate the implementation of the layered decoder architecture. The new matrices proposed in DVB-S2X no longer use such sub-matrices.
