Approximation of dynamical systems using S-systems theory : application to biological systems [PDF]

open access: yesarXiv, 2005
In this paper we propose a new symbolic-numeric algorithm to find positive equilibria of a n-dimensional dynamical system. This algorithm implies a symbolic manipulation of ODE in order to give a local approximation of differential equations with power-law dynamics (S-systems).

Chinese herbal medicine‐derived extracellular vesicle‐like particles: Therapeutic potential and future research approaches

open access: yesInterdisciplinary Medicine, EarlyView.
This article evaluates the therapeutic potential of extracellular vesicle‐like particles derived from Chinese herbal medicine (CHM‐EVLP) for a range of diseases. It underscores the significance of traditional Chinese medicine in the development of innovative formulations.

Non-Destructive Carotenoid Quantification in Leaves via Raman Spectroscopy: Optimizing Treatment for Linear Discriminant Analysis [PDF]

open access: yesarXiv
This study introduces a novel method for quantifying challenging carotenoids in leaf tissues, which typically produce less stable signals than fruits, grains, and roots, by applying Linear Discriminant Analysis (LDA) modeling to interpret Raman spectroscopy data.

Gene splice sites correlate with nucleosome positions [PDF]

open access: yesarXiv, 2004
Gene sequences in the vicinity of splice sites are found to possess dinucleotide periodicities, especially RR and YY, with the period close to the pitch of nucleosome DNA. This confirms previously reported finding about preferential positioning of splice junctions within the nucleosomes.

Developmental Imaging of Radish Sprouts Using Dynamic Optical Coherence Tomography

open access: yesJournal of Biophotonics, EarlyView.
We non‐invasively investigated the germination process of radish sprouts for up to 12 days using volumetric dynamic optical coherence tomography (OCT). This technique analyzes temporal fluctuation in the OCT signal. The dynamic OCT signals in the vessels and growing roots were initially high and decreased with tissue maturation.

Exploiting the molecular diversity of the synapse to investigate neuronal communication: A guide through the current toolkit

open access: yesEuropean Journal of Neuroscience, Volume 56, Issue 12, Page 6141-6161, December 2022., 2022
Chemical synapses are tiny and overcrowded environments enriched with thousands of protein species. Many efforts have been devoted to developing sensors and actuators able to evaluate and control synaptic communication. Most of these recent tools are based on the engineering of one or more specific synaptic proteins used to target active moieties to ...

Hamiltonian dynamics and distributed chaos in DNA [PDF]

open access: yesarXiv, 2018
It is shown that distributed chaos, generated by Hamiltonian DNA dynamics with spontaneously broken time translational symmetry, imprints itself on the DNA sequence of Arabidopsis thaliana (a model plant for genetic sequencing and mapping) and of the NRXN1 and BRCA2 human genes (as an example).

Coordination of photosynthetic traits across soil and climate gradients

open access: yesGlobal Change Biology, Volume 29, Issue 3, Page 856-873, February 2023., 2023
Using an Australia‐wide photosynthetic trait dataset, we tested predictions from least‐cost optimality theory, which posits that plants balance nutrient use and water loss to optimize photosynthesis. We found that leaf nitrogen and rates of water loss co‐vary with one another in response to climate and to a lesser extent, soils.

Effects of Soil Structure on the Growth of Rice Roots

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Soil pore structure has a large impact on plant root architecture, but it is difficult to study due to secondary impacts from bulk density, carbon, nutrients, and other properties. Here, we isolated soil pore structure by forming controlled soil structures in repacked columns. To generate a non‐structured treatment, sieved soil was packed to 1.
