An Avalanche Effect Nanomodulator Triggers Cascade Ferroptosis/Cuproptosis for Immunosuppressive Microenvironment Remodeling

open access: yesAdvanced Science, EarlyView.
A nanomodulator called L‐Arginine/lificiguat@Copper‐hollow Prussian blue@Calcium phosphate nanoparticles is constructed to launch a self‐amplifying “avalanche effect” in tumor cells. The ensuing cascade, triggered by the acidic tumor microenvironment and near‐infrared light, induces calcium overload, generates a reactive oxygen species and reactive ...

A tentative map of discourse studies and their place in Linguistics A tentative map of discourse studies and their place in Linguistics

open access: yesIlha do Desterro, 2008
In this paper I want to look at a range of approaches to discourse analysis with a view not to describing any of them in detail but to seeing how they relate to each other in the discipline. Surveys are a necessary evil at best; they inevitably offend by simplification and omission and ometimes by distortion as well.

3D Printed Meter‐Scale Soft Origami Robots Capable of Load‐Bearing Actuation Via Crease Stiffness Modulation

open access: yesAdvanced Science, EarlyView.
Origami has inspired numerous soft deployable mechanisms for safe human‐robot interaction, while its intrinsic kinematic instability at arbitrary configurations limited their practical robotic application. This work presents a 3D printed meter‐scale origami robotic actuator capable of load‐bearing deformation through creaseline stiffness modulation.

Nucleoside‐Modified mRNA Encoding Alpha‐Galactosidase A Ameliorates Fabry Disease Phenotypes in Human IPSC‐Derived Cardiomyocytes

open access: yesAdvanced Science, EarlyView.
Human iPSC‐derived Fabry cardiomyocytes exhibited broad transcriptional dysregulation, apoptosis, mitochondrial dysfunction, impaired reactive oxygen species handling, altered contractility, and abnormal calcium transient decay, potentially mediated by phospholamban hyperphosphorylation.

Dynamics of skew tent maps

open access: yesDynamics of skew tent maps
This paper deals with the dynamical properties of so-called skew tent maps defined by \[ f_{a,b}(x)= \begin{cases} ax+1, &x\leq 0,\\ -bx+1, &x\geq 0,\end{cases} \tag{1} \] \((a,b)\in D:= \{(a,b)\mid a>0\), \(b>1\), \(a+b\geq ab\}\). Here the authors give the relation between \(*\)-product for a kneading sequence and renormalization.
