From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Pyroelectric sensor for entropy measurements

2014 IEEE 11th International Multi-Conference on Systems, Signals & Devices (SSD14), 2014
In this contribution we propose a system to measure entropy fluctuations in thermal systems. The system consist of a pyroelectric sensor and a temperature sensor. The pyroelectric convert thermal variations into electrical signals so that thermally induced charge is measured and monitored and heat variation can be obtained. Temperature is independently

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Quantifying Information without Entropy: Identifying Intermittent Disturbances in Dynamical Systems

, 2020
A system’s response to disturbances in an internal or external driving signal can be characterized as performing an implicit computation, where the dynamics of the system are a manifestation of its new state holding some memory about those disturbances.

Measuring center of pressure signals to quantify human balance using multivariate multiscale entropy by designing a force platform [PDF]

, 2013
Copyright © 2013 by the authors. To assess the improvement of human body balance, a low cost and portable measuring device of center of pressure (COP), known as center of pressure and complexity monitoring system (CPCMS), has been developed for data ...

On the minimal entropy martingale measure [PDF]

The Annals of Probability, 2002
Let \(X=(X_t)\) \((0\leq t\leq T)\) be a locally bounded semimartingale. Let \(P\) be a reference measure. The authors show that an equivalent martingale measure \(\overline Q\) for \(X\) satisfying the following three conditions minimizes relative entropy \(I(Q,P)\) among all martingale measures \(Q\): (i) \(dP/d\overline Q\in L^\varepsilon(P)\) for ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

On Intuitionistic Fuzzy Entropy of Order-α

Advances in Fuzzy Systems, 2014
Using the idea of Rènyi’s entropy, intuitionistic fuzzy entropy of order-α is proposed in the setting of intuitionistic fuzzy sets theory. This measure is a generalized version of fuzzy entropy of order-α proposed by Bhandari and Pal and intuitionistic ...

Entropy and Energy in Quantum Measurement [PDF]

Entropy, 2006
On the basis of the classical axioms of non relativistic quantum mechanics, we develop a model for the interplay between energy and entropy in the process of quantum measurement and shed light on the scope of some of the axioms with regard to the measurement problem.
