Explicit Space-Time Codes Achieving The Diversity-Multiplexing Gain Tradeoff
, 2006 A recent result of Zheng and Tse states that over a quasi-static channel, there exists a fundamental tradeoff, referred to as the diversity-multiplexing gain (D-MG) tradeoff, between the spatial multiplexing gain and the diversity gain that can be ...

FEBS Open Bio, EarlyView.Chemoresistance in bladder cancer: Macrophage recruitment associated with CXCL1, CXCL5 and CXCL8 expression is characteristic of Gemcitabine/Cisplatin (Gem/Cis) Non‐Responder tumors (right side) while Responder tumors did not show substantial tumor‐stromal crosstalk (left side). All biological icons are attributed to Bioicons: carcinoma, cancerous‐cell‐

Source Coding for Quasiarithmetic Penalties
, 2006 Huffman coding finds a prefix code that minimizes mean codeword length for a given probability distribution over a finite number of items. Campbell generalized the Huffman problem to a family of problems in which the goal is to minimize not mean codeword

FEBS Open Bio, EarlyView.ZFAS1 is a lncRNA promoting cell proliferation and migration, exhibiting high expression in various cancers. It is conserved, widely expressed, and produces multiple splice variants with unclear roles. We identified several splice variants in hepatocyte models, and found that inhibiting or suppressing regulators of the unfolded protein response (PERK ...

Noncoherent Low-Decoding-Complexity Space-Time Codes for Wireless Relay Networks
, 2007 The differential encoding/decoding setup introduced by Kiran et al, Oggier et al and Jing et al for wireless relay networks that use codebooks consisting of unitary matrices is extended to allow codebooks consisting of scaled unitary matrices.

On the use of Reed-Solomon codes in Space-Time Coding
2005 IEEE 16th International Symposium on Personal, Indoor and Mobile Radio Communications, 2006 In this paper, we present an original use of Reed-Solomon (RS) codes as space-time block codes (STBCs) and compare them to orthogonal STBCs (OSTBCs). Due to their symbol structure, they can have a representation close to that of an STBC. RS codes are admittedly more complex to decode as they have no orthogonal properties.

FEBS Open Bio, EarlyView.Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

SPACE TIME CODING FOR TRELLIS CODED MODULATION IN ADDITIVE WHITE GAUSSIAN CHANNELS
Electrica, 2003 In this study, Trellis Coded Modulation (TCM) technique is combined with Space Time Codes (STC) and error performance is investigated in Additive White Gaussian (AWGN) channels. For this purpose a different receiver structure is proposed and mathematical
