Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Suffix-Sorting via Shannon-Fano-Elias Codes
Algorithms, 2010 Given a sequence T = t0t1 . . . tn-1 of size n = |T|, with symbols from a fixed alphabet Σ, (|Σ| ≤ n), the suffix array provides a listing of all the suffixes of T in a lexicographic order.

Finite-Length Analyses for Source and Channel Coding on Markov Chains
Entropy, 2020 We derive finite-length bounds for two problems with Markov chains: source coding with side-information where the source and side-information are a joint Markov chain and channel coding for channels with Markovian conditional additive noise.

Source-Channel Diversity for Parallel Channels
, 2004 We consider transmitting a source across a pair of independent, non-ergodic channels with random states (e.g., slow fading channels) so as to minimize the average distortion. The general problem is unsolved. Hence, we focus on comparing two commonly used

Screening for lung cancer: A systematic review of overdiagnosis and its implications
Molecular Oncology, EarlyView.Low‐dose computed tomography (CT) screening for lung cancer may increase overdiagnosis compared to no screening, though the risk is likely low versus chest X‐ray. Our review of 8 trials (84 660 participants) shows added costs. Further research with strict adherence to modern nodule management strategies may help determine the extent to which ...

Entropy, 2017 In the present paper, we obtain a result on the rate-distortion function (RDF) of wide sense stationary (WSS) vector processes that allows us to reduce the complexity of coding those processes.

Gaussian Source Coding using a Simple Switched Quantization Algorithm and Variable Length Codewords
Advances in Electrical and Computer Engineering, 2020 This paper introduces an algorithm based on switched scalar quantization utilizing a novel Îź-law quantization model (optimized in terms of minimal distortion) and variable length codewords, for high-quality encoding of the signals modeled by Gaussian ...

Molecular Oncology, EarlyView.Urinary LGALS3BP is elevated in bladder cancer patients compared to healthy controls as detected by the 1959 antibody–based ELISA. The antibody shows enhanced reactivity to the high‐mannose glycosylated variant secreted by cancer cells treated with kifunensine (KIF).

Distributed Joint Source-Channel Coding-Based Adaptive Dynamic Network Coding
IEEE Access, 2020 Distributed Source Coding (DSC) schemes rely on separate encoding but joint decoding of statistically dependent sources, which exhibit correlation. More specifically, Distributed Joint Source-Channel coding (DJSC) is associated with the scenario, where ...
