„Hydrophob“ oder einfach „nicht hydrophil genug“? Warum sich Öl nicht in Wasser löst

open access: yesCHEMKON, EarlyView.
Die geringe Löslichkeit unpolarer Stoffe in Wasser wird in Schulbüchern oft energetisch begründet, indem die starken Wasserstoffbrücken zwischen Wassermolekülen nicht durch schwache Van‐der‐Waals‐Wechselwirkungen überwunden werden könnten. Experimentelle Daten zeigen jedoch, dass der Lösungsvorgang von Alkanen in Wasser sogar exotherm verläuft und die ...

Simple permutations with order $4n + 2$. Part I [PDF]

open access: yes, 2011
The problem of genealogy of permutations has been solved partially by Stefan (odd order) and Acosta-Hum\'anez & Bernhardt (power of two). It is well known that Sharkovskii's theorem shows the relationship between the cardinal of the set of periodic ...

Enhancing Knowledge and Technology Transfer: Determinants and Indicators of Successful University–Industry Collaboration

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Both universities and companies create value and innovation to maintain their position and remain competitive. Different, but still similar, with two goals that are shared. With their collaboration, they can enhance their pursuit of sustainability and as well corporate social responsibility by creating and delivering value and thus ...

Quenching the Hubbard Model: Comparison of Nonequilibrium Green's Function Methods

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT We benchmark nonequilibrium Green's function (NEGF) approaches for interaction quenches in the half‐filled Fermi–Hubbard model in one and two dimensions. We compare fully self‐consistent two‐time Kadanoff–Baym equations (KBE), the generalized Kadanoff–Baym ansatz (GKBA), and the recently developed NEGF‐based quantum fluctuations approach (NEGF‐

Approximate Analytic Solutions for the Two-Phase Stefan Problem Using the Adomian Decomposition Method

open access: yesJournal of Applied Mathematics, 2014
An Adomian decomposition method (ADM) is applied to solve a two-phase Stefan problem that describes the pure metal solidification process. In contrast to traditional analytical methods, ADM avoids complex mathematical derivations and does not require ...

Are seizure forecasts and cycles better than chance? What chance?

open access: yesEpilepsia, EarlyView.
Abstract Objective There is a growing synergy between the lines of research on cycles in epilepsy and seizure forecasting. It has been conjectured, for instance, that incorporating information about significant seizure cycles into forecasting algorithms can lead to a better‐than‐chance forecasting performance.

A multicenter, video‐EEG‐based validation of a multimodal wearable device for focal seizure detection in adults: The SeizeIT2 study

open access: yesEpilepsia Open, EarlyView.
Abstract Objective Currently available wearable devices for detecting focal seizures primarily target major motor seizures or involve semi‐invasive subscalp implants. There is a pressing need for accurate, non‐invasive methods to detect diverse focal seizures for long‐term, out‐of‐hospital monitoring.
