Detection of fixed points in spatiotemporal signals by clustering method

open access: yes, 2000
We present a method to determine fixed points in spatiotemporal signals. A 144-dimensioanl simulated signal, similar to a Kueppers-Lortz instability, is analyzed and its fixed points are reconstructed.Comment: 3 pages, 3 ...

Liquid Metal‐Exfoliated SnO2‐Based Mixed‐Dimensional Heterostructures for Visible‐to‐Near‐Infrared Photodetection

open access: yesAdvanced Optical Materials, EarlyView.
Two dimensional (2D) atomically thin materials hold significant promise for next‐generation photodetectors but are limited by low light absorption and scalability challenges. This study presents a high‐performance photodetector integrating liquid metal‐derived 2D SnO2 with CdTe, enabling efficient visible to near‐infrared detection and offering a ...

The Introduction of Mapping Cultures in European Archaeology - Time Meets Space

open access: yesEtnoantropološki Problemi, 2017
Prehistoric archaeology derives its roots from various practices and sciences: antiquarianism, natural history, geology, philology etc. The key conceptual tools of archaeology, including its “basic bloc” – archaeological culture, were formed by the end ...

Nonlinear Optical Properties of Mono and Multilayer MoWSe2 Alloys

open access: yesAdvanced Optical Materials, EarlyView.
We employ second‐harmonic generation and two‐photon photoluminescence to probe the excitonic resonances and exciton binding energy in Mo(1x)WxSe2 alloys as a function of composition and layer number. Our work lays the groundwork for understanding the optical and electronic properties of TMD alloys, a crucial step toward next‐generation optoelectronic ...

Bóg spoza nawiasu egzystencji. Max Scheler – mistyka czy fenomenologia aktowego zjednoczenia? [PDF]

open access: yesArgument, 2016
This article presents in the first part the concept of Schelerian phenomenology of religion and claims that pre‑phenomenon of Holiness could not be take in the bracket of existence as usual because the religious act raised by Holiness itself is an ...

Drainage Adits in Upper Silesia – Industrial Technology Heritage and Important Elements of the Hydrotechnical Infrastructure

open access: yesStudia Geotechnica et Mechanica, 2017
Adits played an important role in the hydrotechnical infrastructure for centuries. Initially, they were used mainly to drain wetland and supply water to the population. There were also inherent in the conduct of mining activities.

Reconstructing the intermittent dynamics of the torque in wind turbines

open access: yes, 2014
We apply a framework introduced in the late nineties to analyze load measurements in off-shore wind energy converters (WEC). The framework is borrowed from statistical physics and properly adapted to the analysis of multivariate data comprising wind ...

Tuning Charge‐Separated State Lifetimes in Perovskite Nanocrystal‐Perylenediimide Hybrids

open access: yesAdvanced Optical Materials, EarlyView.
Functional perylenediimides with varied spacer lengths surface engineer CsPbBr₃ perovskite nanocrystals, yielding hybrid materials with new properties. Time‐resolved techniques reveal photoinduced charge separation from perovskite nanocrystals to perylenediimides, with microsecond‐lived charge carriers. Spacer length modulates charge carrier lifetimes,

Gaspar de Jovellanos and Friedrich Carl von Savigny: their resort to philology and their contribution to the discipline Gaspar de Jovellanos y Friedrich von Savigny: el recurso a la filología y su aportación a la disciplina

open access: yesCuadernos Dieciochistas, 2012
This article explores the similarities between Gaspar de Jovellanos» and Friedrich Carl von Savigny’s approaches to medieval legal documents. Both deal with the difficulties to comprehend medieval legal texts which constitute a hermeneutical approach ...
