Quantitative bounds in the polynomial Szemerédi theorem: the homogeneous case

open access: yesDiscrete Analysis, 2017
Quantitative bounds in the polynomial Szemerédi theorem: the homogeneous case, Discrete Analysis 2017:5, 34 pp. Szemerédi's theorem, proved in 1975, asserts that for every positive integer $k$ and every $\delta>0$ there exists $n$ such that every subset

Periodic solutions for first-order cubic non-autonomous differential equation with bifurcation analysis

open access: yesJournal of Taibah University for Science, 2020
This article deals with the development of the number of periodic solutions for ordinary differential equations. We investigated focal values for first-order non-autonomous differential equation for periodic solutions from a fine focus $\mathfrak {z}=0 $.

Projective equivalence of homogenous binary polynomials

open access: yesLinear Algebra and its Applications, 1989
The aim is to define new sets of invariants for complex projective equivalence \({\mathcal E}_ p\) defined on the set \({\mathbb{C}}_ k\) of complex homogeneous binary polynomials of fixed degree k. It will be shown that the characterization of the class \({\mathcal E}_ p(f)\) by invariants is equivalent to a problem of algebraic projective geometry ...

Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Cardiac‐Derived ECM Microspheres for Enhanced hiPSC‐CMs Maturation

open access: yesAdvanced Functional Materials, EarlyView.
Cardiac extracellular matrix microspheres derived from decellularized porcine heart provide a biomimetic 3D microenvironment for human induced pluripotent stem cell–derived cardiomyocytes (hiPSC‐CMs). This platform supports short‐ and long‐term culture, enhances structural organization, and promotes electrophysiological and functional maturation of ...

Homogeneous polynomial maps

open access: yesIndagationes Mathematicae (Proceedings), 1984
Der Raum aller homogenen Polynome k-ten Grades P(k,n) über \(K\in \{{\mathbb{C}},{\mathbb{R}}\}\) in n Variablen hat eine bestimmte Dimension N. Für ein l.u. p-Tupel \(F:=(f_ 1,...,f_ p)\), \(f_ i\in P(k,n)\), \(K={\mathbb{C}}\), wird sehr leicht gezeigt: \(\alpha)\) \(| F(z)| \equiv | z|^ k\) kann im Falle \(p\neq N\) nicht auftreten.

MagPiezo: A Magnetogenetic Platform for Remote Activation of Endogenous Piezo1 Channels in Endothelial Cells

open access: yesAdvanced Functional Materials, EarlyView.
MagPiezo enables wireless activation of endogenous Piezo1 channels without genetic modification using 19 nm magnetic nanoparticles and low‐intensity magnetic fields. It generates torque forces at the piconewton scale to trigger mechanotransduction in endothelial cells, standing as a novel platform to interrogate and manipulate Piezo1 activity in vitro.
