Physics‐Informed Neural Network‐Enabled Forward Prediction and Inverse Design of Ring Origami
Advanced Science, EarlyView.This work presents a KRT‐PINN framework that integrates Kirchhoff rod theory with physics‐informed neural networks for the forward prediction and inverse design of ring origami consisting of closed‐loop rods. The framework predicts stable states of segmented rings with prescribed natural‐curvature profiles and determines the natural‐curvature profiles ...

On Segmented Predistortion for Linearization of RF Power Amplifiers [PDF]
Radioengineering, 2020 This paper presents a general survey of digital predistortion (DPD) techniques with segmentation. A comparison of global DPD with two segmented approaches namely Vector-Switched DPD and Decomposed Vector Rotation DPD is presented with the support of ...

O dvou flexibilních metodách pro dvourozměrnou regresní analýzu [PDF]
ACC Journal, 2012 Práce je věnována neparametrickému statistickému modelování dvourozměrných ploch na základě pozorovaných dat, tj. dvourozměrně regresni analýze. Model je konstruován jako kombinace jednoduchých bázových funkcí, jako jsou spliny, gaussiány apod. Nevýhodou

Advanced Science, EarlyView.Employing a digital single‐molecule activity tracker (dSMAT), this research demonstrates that high‐photon‐flux irradiation drives progressive oxidative scarring in polymerases. Unlike simple thermal denaturation, real‐time kinetic tracking dynamically visualizes enzymes degrading into multiple impaired subpopulations.

Ban Glyphosate—Does It Affect the Swedish Farmers' Willingness to Grow Cover Crops?
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT The cultivation of cover crops is one of the new Eco‐scheme practices introduced in Sweden. This study examines how the design of policy attributes of these schemes influences farmers' willingness to grow cover crops on arable land, with particular focus on the potential impact of a glyphosate ban.
