Severe Restriction of Glucose Import Enhances Recombinant Protein Production in Escherichia coli. [PDF]

Biotechnol J
Graphical Abstract and Lay Summary Producing recombinant proteins in Escherichia coli is often limited by the bacterium's tendency to consume glucose too rapidly. This excessive glucose uptake causes overflow metabolism, leading to the accumulation of acetate, a byproduct that can reduce cellular performance and protein production.

Generating Dynamic Structures Through Physics-Based Sampling of Predicted Inter-Residue Geometries. [PDF]

Adv Sci (Weinh)
While static structure prediction has been revolutionized, modeling protein dynamics remains elusive. trRosettaX2‐Dynamics is presented to address this challenge. This framework leverages a Transformer‐based network to predict inter‐residue geometric constraints, guiding conformation generation via physics‐based iterative sampling. The resulting method

Upper Bounds on the BER Performance of MTCM-STBC Schemes over Shadowed Rician Fading Channels

EURASIP Journal on Advances in Signal Processing, 2004
Space-time block coding (STBC) provides substantial diversity advantages with a low decoding complexity. However, these codes are not designed to achieve coding gains. Outer codes should be concatenated with STBC to provide additional coding gain.

Neural Dynamics of Social Cognition: A Single-Trial Computational Analysis of Learning Under Uncertainty. [PDF]

Hum Brain Mapp
We apply a hierarchical Bayesian model to single‐trial EEG data from an advice‐taking task, demonstrating that EEG activity closely mirrors the predicted sequence of prediction errors and precision signals. Additionally, source‐localised activity in the fusiform gyrus and posterior cingulate cortex covaried with participants' psychosocial functioning ...

Distributed Space-Time Block Code over Mixed Rayleigh and Rician Frequency-Selective Fading Channels

EURASIP Journal on Wireless Communications and Networking, 2010
This paper proposes a new distributed space-time block code (DSTBC) over frequency-selective fading channels for two-hop amplify and forward relay networks, consisting of a source node (S), two relay nodes (R1 and R2), and a destination node (D).

A Novel Error Detection due to Joint CRC Aided Denoise-and-Forward Network Coding for Two-Way Relay Channels

The Scientific World Journal, 2014
In wireless two-way (TW) relay channels, denoise-and-forward (DNF) network coding (NC) is a promising technique to achieve spectral efficiency. However, unsuccessful detection at relay severely deteriorates the diversity gain, as well as end-to-end ...

Polar Codes With Repeating Bits and the Construction by Cluster Pairwise Error Probability

IEEE Access, 2019
A polar code with repeating bits (RB polar code), where a part of frozen bits only repeat their preceding information bits, is proposed. In the code construction, we propose cluster pairwise error probability (CPEP) to measure the competitiveness of the ...

New Design of Constellation and Bit Mapping for Dual Mode OFDM-IM

IEEE Access, 2019
Dual mode orthogonal frequency division multiplexing with index modulation (DM-OFDM-IM) is recently proposed, where the subcarriers within each subblock are divided into two groups, which are modulated by two distinguishable signal constellations.
