Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background The delipid extracorporeal lipoprotein filter from plasma (DELP) treatment can effectively reduce blood lipid, increase blood flow, and improve neurological deficits in patients with acute ischemic stroke (AIS). However, its effect on vision and retinal microcirculation in stroke patients has never been reported.

On Particle Swarm Optimization for MIMO Channel Estimation
Journal of Electrical and Computer Engineering, 2012 Evolutionary algorithms, in particular particle swarm optimization (PSO), have recently received much attention. PSO has successfully been applied to a wide range of technical optimization problems, including channel estimation.

QCD Theory Meets Information Theory
Physical Review LettersWe present a novel technique to incorporate precision calculations from quantum chromodynamics into fully differential particle-level Monte Carlo simulations. By minimizing an information-theoretic quantity subject to constraints, our reweighted Monte Carlo incorporates systematic uncertainties absent in individual Monte Carlo predictions, achieving ...

Frequency Value Grammar and Information Theory [PDF]
, 2004 I previously laid the groundwork for Frequency Value Grammar (FVG) in papers I submitted in the proceedings of the 4th International Conference on Cognitive Science (2003), Sydney Australia, and Corpus Linguistics Conference (2003), Lancaster, UK. FVG is

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Philentropy: Information Theory and Distance Quantification with R
Journal of Open Source Software, 2018 Comparison is a fundamental method of scientific research leading to insights about the processes that generate similarity or dissimilarity. In statistical terms comparisons be-tween probability functions are performed to infer connections, correlations,

Covert channel detection using Information Theory
, 2010 This paper presents an information theory based detection framework for covert channels. We first show that the usual notion of interference does not characterize the notion of deliberate information flow of covert channels.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Information Theory and Cognition: A Review
Entropy, 2018 We examine how information theory has been used to study cognition over the last seven decades. After an initial burst of activity in the 1950s, the backlash that followed stopped most work in this area. The last couple of decades has seen both a revival
