Chemical Doping Engineering of Polarization and Topological Textures in van der Waals Ferroelectric CuInP2S6

open access: yesAdvanced Science, EarlyView.
Our work reports that Li⁺ doping in CuInP2S₆ induces coexistence of high‐ and low‐polarization states, which fosters a rich spectrum of topological polar textures, such as bubbles and labyrinth domains. An unconventional flexoelectric effect is also discovered, where strain gradients can mechanically manipulate these polarization states and their ...

Les charmes de la physique selon François-Joseph Hunauld : machines-cadavres et merveilleux végétal

open access: yesFééries, 2019
The New Treatise on Physics, a little-known work by François-Joseph Hunauld (1701-1742), was published in 1742. Noteworthy for being his only attempt to adorn science with fictional elements, the New Treatise drew its main inspiration from Fontenelle’s ...

Three Questions on Lorentz Violation [PDF]

open access: yes, 2006
We review the basics of the two most widely used approaches to Lorentz violation - the Stardard Model Extension and Noncommutative Field Theory - and discuss in some detail the example of the modified spectrum of the synchrotron radiation.

Universally Accurate or Specifically Inadequate? Stress‐Testing General Purpose Machine Learning Interatomic Potentials

open access: yesAdvanced Intelligent Discovery, EarlyView.
We investigate MACE‐MP‐0 and M3GNet, two general‐purpose machine learning potentials, in materials discovery and find that both generally yield reliable predictions. At the same time, both potentials show a bias towards overstabilizing high energy metastable states. We deduce a metric to quantify when these potentials are safe to use.

The methodology of harmonic convergence for the worldview of universalism [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Серия Философия. Психология. Педагогика
Introduction. The article is devoted to methodological issues of the formation of the worldview of universalism, excluding the reduction of the one, the whole, many and a part to each other.

Libet's experiment provides no evidence against strong libertarian free will because readiness potentials do not cause our actions [PDF]

open access: yes, 2012
This article argues against Benjamin Libet's claim that his experiment has shown that our actions are caused by brain events which begin before we decide and before we even think about the action.

A Multimodal Laser‐Induced Graphene‐Based Flexible Sensor for Soft Robotic Hand Environmental Perception

open access: yesAdvanced Intelligent Systems, EarlyView.
A multimodal laser‐induced graphene (LIG)‐based flexible sensor is developed to detect proximity and contact signals. Integrated into a soft robotic hand, it enables vision‐free object searching and grasping. Combined with a convolutional neural network, the system achieves accurate material and texture recognition, enhancing the capability of ...

Libet's experiment provides no evidence against strong libertarian free will because it does not investigate voluntary actions [PDF]

open access: yes, 2012
It is widely believed that Libet's experiment has shown that all our actions have preceding unconscious causes. This article argues that Libet's claim that the actions he investigated are voluntary is false.

Impact of Seasonal Composition on the Long‐Term Performance of Post‐Consumer Recycled Polypropylene

open access: yesJournal of Applied Polymer Science, EarlyView.
Ten batches of post‐consumer polypropylene recyclate were examined over a period of 15 months. Despite identical MFR and density specifications, there were significant differences in their composition, affecting mechanical performance. Elongation at break and crack resistance varied particularly strongly.

Is the Cell Really a Machine? [PDF]

open access: yes, 2019
It has become customary to conceptualize the living cell as an intricate piece of machinery, different to a man-made machine only in terms of its superior complexity.
