Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Improving the Minimum Free Energy Principle to the Maximum Information Efficiency Principle

open access: yesEntropy
Friston proposed the Minimum Free Energy Principle (FEP) based on the Variational Bayesian (VB) method. This principle emphasizes that the brain and behavior coordinate with the environment, promoting self-organization. However, it has a theoretical flaw,

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

open access: yesMolecular Oncology, Volume 20, Issue 6, Page 1513-1534, June 2026.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Second-order maximum principle controlled weakly singular Volterra integral equations [PDF]

open access: yesArchives of Control Sciences
This work studies a class of singular Volterra integral equations that are (controlled) and can be applied to memory-related problems. For optimum controls, we prove a second-order Pontryagin type maximal principle.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Hopf maximum principle revisited

open access: yesElectronic Journal of Differential Equations, 2015
A weak version of Hopf maximum principle for elliptic equations in divergence form $$ \sum_{i,j=1}^N\partial_i(a_{ij}(x)\partial_ju)=0 $$ with Holder continuous coefficients $a_{ij}$ was shown in [3], in the two-dimensional case.

Pontryagin Maximum Principle for Incommensurate Fractional-Orders Optimal Control Problems

open access: yesMathematics, 2023
We introduce a new optimal control problem where the controlled dynamical system depends on multi-order (incommensurate) fractional differential equations.

Stochastic Maximum Principle

open access: yes, 2014
International audienceThe stochastic maximum principle (SMP) gives some necessary conditions for optimality for a stochastic optimal control problem. We give a summary of well-known results concerning stochastic maximum principle in finite-dimensional ...

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

open access: yesMolecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Combining experiments and simulations using the maximum entropy principle. [PDF]

open access: yesPLoS Computational Biology, 2014
A key component of computational biology is to compare the results of computer modelling with experimental measurements. Despite substantial progress in the models and algorithms used in many areas of computational biology, such comparisons sometimes ...
