Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Wavelet analysis of spatial coherent structures in the photosphere

open access: yes, 1999
In this work we present some applications of wavelet analysis to the dynamics of the photosphere as obtained from a good serie of high spatial resolution white light images taken at the Vacuum Tower Telescope (VTT) at the NSO/SPO in October 1996. The use

Identification of Thermally-Tagged Coherent Structures in the Zero Pressure Gradient Turbulent Boundary Layer [PDF]

open access: yes, 2013
A zero pressure gradient boundary layer over a flat plate is subjected to step changes in thermal condition at the wall, causing the formation of internal, heated layers.

On the late phase of relaxation of two-dimensional fluids: turbulence of unitons

open access: yesNew Journal of Physics, 2017
The two-dimensional ideal fluid and the plasma confined by a strong magnetic field exhibit an intrinsic tendency to organization due to the inverse spectral cascade. In the asymptotic states reached at relaxation the turbulence has vanished and there are

Proper Orthogonal Decomposition Analysis of Turbulent Energy Spectra within a Lagrangian Particle Tracking Framework [PDF]

open access: yesJournal of Applied and Computational Mechanics
This paper proposes an approach that applies Proper Orthogonal Decomposition (POD) analysis to experimental data obtained using the Lagrangian Particle Tracking (LPT) technique from the original experimental work [1]. Based on the experiment description,

Self‐Regulated Learning Meets AI: Reinterpreting Self‐Regulation, Co‐Regulation, and Socially Shared Regulation in Human–AI Interaction

open access: yesNew Directions for Adult and Continuing Education, EarlyView.
ABSTRACT Advancing artificial intelligence (AI) has transformed learning and work, yet higher education and professional development programs have not systematically equipped learners for AI‐prevalent environments. This lack of preparation creates uncertainty regarding control, responsibility, trust, and accountability.

Coherent structures: Comments on mechanisms [PDF]

open access: yes, 1987
There is now overwhelming evidence that in most turbulent flows there exist regions moving with the flow where the velocity and vorticity have a characteristic structure.

Optical model for multilayer structures with coherent, partly coherent and incoherent layers [PDF]

open access: yes, 2013
We present a novel approach for modeling the reflectance, transmittance and absorption depth profile of thin-film multilayer structures such as solar cells.

Dynamical systems theory approach in oceanography: a review on achievements, limitations, verification and validation of Lagrangian methods

open access: yesFrontiers in Marine Science
The Lagrangian approach (LA) in ocean modelling relies on a dense set of trajectories of virtual particles that can be computed using velocity fields and on a subsequent analysis of entangled trajectories of particles.

Data-Driven Pulsatile Blood Flow Physics with Dynamic Mode Decomposition

open access: yesFluids, 2020
Dynamic mode decomposition (DMD) is a purely data-driven and equation-free technique for reduced-order modeling of dynamical systems and fluid flow. DMD finds a best fit linear reduced-order model that represents any given spatiotemporal data.
