Multi-level Turbo Decoding Assisted Soft Combining Aided Hybrid ARQ [PDF]

open access: yes, 2010
Hybrid Automatic Repeat reQuest (ARQ) plays an essential role in error control. Combining the incorrectly received packet replicas in hybrid ARQ has been shown to reduce the resultant error probability, while improving the achievable throughput.

Sliding-Window Turbo Equalization and Its Reduced-Complexity Decoding Techniques

open access: yesIEEE Access, 2022
Turbo equalization is a cooperative error-correcting approach to achieve a target bit-error rate over inter-symbol interference channels. In this paper, we proposed a new turbo equalization, called sliding-window turbo equalization (SW-TE), consisting of

Relay Switching Aided Turbo Coded Hybrid-ARQ for Correlated Fading Channel

open access: yes, 2011
Hybrid-Automatic-Repeat-reQuest (HARQ) has become an indispensable technique in reliable communications systems. However, its performance is inevitably affected by the channel’s fading correlation. In this paper, we proposed a novel relay-switching aided

Dysfunctional tetraspanin 7 (TSP‐7) in Caenorhabditis elegans promotes; increases in average life‐ & health‐span, stress‐induced survival and motility

open access: yesFEBS Open Bio, EarlyView.
The C. elegans tetraspanin‐7 (tsp‐7) is a homologue of human CD63, which is a negative regulator of autophagy. The C. elegans strain, tm5761, has a dysfunctional (knockout) tsp‐7 gene. When compared to the wild‐type strain, the tm5761 strain shows increased: life‐ and health‐span; thermotolerance, and stress‐induced locomotion.

Exploration of agricultural residue ash as a solid green heterogeneous base catalyst for biodiesel production

open access: yesEngineering Reports, Volume 5, Issue 1, January 2023., 2023
Transesterification of vegetable oils with homogeneous catalyst for biodiesel synthesis is considered to have a promising future, but it is nonrenewable and hazardous. High production cost, in terms of feedstock oil and catalyst acquisition is one of the major challenges facing the global commercialization of biodiesel.

Adenosine A3 receptor antagonists as anti‐tumor treatment in human prostate cancer: an in vitro study

open access: yesFEBS Open Bio, EarlyView.
The A3 adenosine receptors (A3ARs) are overexpressed in prostate cancer. AR 292 and AR 357, as A3AR antagonists, are capable of blocking proliferation, modulating the expression of drug transporter genes involved in chemoresistance, ferroptosis, and the hypoxia response, and inducing cell death.

Numerical Investigation of the Excitation Characteristics of Contaminated Nozzle Rings

open access: yesInternational Journal of Turbomachinery, Propulsion and Power
The deposition of combustion residues in the nozzle ring (NR) of a turbocharger turbine stage changes the NR geometry significantly in a random manner. The resultant complex and highly asymmetric geometry induces low engine order (LEO) excitation, which ...
