Methods for the Reconstruction of Parallel Turbo Codes [PDF]

arXiv, 2010
We present two new algorithms for the reconstruction of turbo codes from a noisy intercepted bitstream. With these algorithms, we were able to reconstruct various turbo codes with realistic parameter sizes. To the best of our knowledge, these are the first algorithms able to recover the whole permutation of a turbo code in the presence of high noise ...

The Novel Dual GIP and GLP‐1 Receptor Agonist Tirzepatide Attenuates Colon Cancer Development by Regulating Glucose Metabolism

Advanced Science, EarlyView.
Tirzepatide, a dual GIP/GLP‐1 receptor agonist for diabetes, suppresses colorectal cancer growth by targeting glucose metabolism. It inhibits cancer cell proliferation, promotes apoptosis, and induces tumor regression. It reduces glucose uptake and destabilizes HIF‐1α for degradation to downregulate PFKFB3/PFK‐1 enzymes, thus contributing to the ...

In vitro cytocompatibility and antibacterial studies on biodegradable Zn alloys supplemented by a critical assessment of direct contact cytotoxicity assay

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 111, Issue 2, Page 241-260, February 2023., 2023
Abstract In vitro cytotoxicity assessment is indispensable in developing new biodegradable implant materials. Zn, which demonstrates an ideal corrosion rate between Mg‐ and Fe‐based alloys, has been reported to have excellent in vivo biocompatibility.

Efficient and Specific PDGFRβ‐Targeting Dual‐Mode T1‐T2 MRI Nanoprobe for Early Diagnosis of Non‐Alcoholic Fatty Liver

Advanced Science, EarlyView.
The Fe3O4/Gd@BSA‐pPB nanoprobe leverages biomimetic mineralization and targets hepatic stellate cells (HSCs) through PDGFRβ, offering superior enrichment in fibrotic regions. This targeted delivery overcomes biological barriers, enhancing both the accuracy and sensitivity of MRI imaging at early disease stages.

Parallel Interleaver Design for a High Throughput HSPA+/LTE Multi-Standard Turbo Decoder [PDF]

, 2014
To meet the evolving data rate requirements of emerging wireless communication technologies, many parallel architectures have been proposed to implement high throughput turbo decoders. However, concurrent memory reading/writing in parallel turbo decoding architectures leads to severe memory conflict problem, which has become a major bottleneck for high

Catheter Injectable Multifunctional Biomaterial for the Treatment of Infected Enterocutaneous Fistulas

Advanced Science, EarlyView.
A multi‐functional shear‐thinning hydrogel is engineered to treat enterocutaneous fistulas. This hydrogel can resist external pressures allowing it to remain within the fistula tract and is shown to have significant antimicrobial, pro‐healing, and anti‐inflammatory properties, which were validated in in vitro and in vivo experiments.

Reproducibility of 3 T APT‐CEST in Healthy Volunteers and Patients With Brain Glioma

Journal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 206-215, January 2023., 2023
Background Amide proton transfer (APT) imaging is a chemical exchange saturation transfer (CEST) technique offering potential clinical applications such as diagnosis, characterization, and treatment planning and monitoring in glioma patients. While APT‐CEST has demonstrated high potential, reproducibility remains underexplored.

VHDL Implementation of different Turbo Encoder using Log-MAP Decoder [PDF]

Journal of Telecommunications, Volume 2, Issue 1, p49-53, April 2010, 2010
Turbo code is a great achievement in the field of communication system. It can be created by connecting a turbo encoder and a decoder serially. A Turbo encoder is build with parallel concatenation of two simple convolutional codes. By varying the number of memory element (encoder configuration), code rate (1/2 or 1/3), block size of data and iteration,

Confined Migration Drives Stem Cell Differentiation

Advanced Science, EarlyView.
Human mesenchymal stem cell (hMSC) homing to sites of regeneration requires navigation through mechanically confining extracellular matrix environments, inducing rapid and dramatic morphological adaptation. By exposing hMSCs to specific levels of physiological confinement, it is demonstrated that confinement can induce osteogenesis, and that this fate ...

Fully Parallel Turbo Equalization for Wireless Communications

IEEE Access, 2015
Iterative turbo equalization is capable of achieving impressive performance gains over the conventional non-iterative equalization having the same complexity, when communicating over channels that suffer from intersymbol interference (ISI).
