Bio-Inspired Textiles for Self-Driven Oil–Water Separation—A Simulative Analysis of Fluid Transport

Biomimetics
In addition to water repellency, superhydrophobic leaves of plants such as Salvinia molesta adsorb oil and separate it from water surfaces. This phenomenon has been the inspiration for a new method of oil–water separation, the bionic oil adsorber (BOA ...

Inter-Dye Distance Distributions Studied by a Combination of Single-Molecule FRET-Filtered Lifetime Measurements and a Weighted Accessible Volume (wAV) Algorithm

Molecules, 2014
Förster resonance energy transfer (FRET) is an important tool for studying the structural and dynamical properties of biomolecules. The fact that both the internal dynamics of the biomolecule and the movements of the biomolecule-attached dyes can occur ...

Bianchi and Hilbert–Blumenthal quaternionic orbifolds

Geometriae Dedicata, 2023
In a series of papers, published in Mathematische Annalen, Bianchi and Blumenthal introduced the notions of Bianchi orbifolds and Hilbert-Blumnethal surfaces as generalizations of modular curves associated to quadratic fields. In this paper, in the same spirit, and following a similar line of reasoning, we introduce the concept of Bianchi and Hilbert ...

ENTANGLED PUBLIC ESSENTIALS: Female Perspectives on Public Toilets in Portugal and How to Propel Change

International Journal of Urban and Regional Research, EarlyView.
Abstract Women living in more affluent urban contexts have poor access to sanitary infrastructures owing to a lack of female public toilets. Existing toilets are often poorly maintained, and their design does not suit women’s daily needs. In this essay I use a mixed‐methods approach that combines the analysis of documents and secondary sources with the

Blumenthal's Theorem for Laurent Orthogonal Polynomials

Journal of Approximation Theory, 2002
The authors study polynomials which satisfy a three-term recurrence relation \(B_n(x)=(x-\beta_n)B_{n-1}(x)-\alpha_n xB_{n-2}(x)\) with positive coefficients \(\alpha_{n+1}, \beta_n\) and show that their zeros are eigenvalues of structured Hessenberg matrices. The case when \(\alpha_n \to\alpha\) and \(\beta_n \to\beta\) is analysed in more detail. Now

Why HR Has Failed to Address Healthcare's Workforce Crisis: The Need for a Systems Partner Role

Human Resource Management Journal, EarlyView.
ABSTRACT Attempts to remedy sustained workforce challenges facing healthcare organizations globally have been largely ineffective, despite increased political attention. In this paper we draw on contextually based human resource theory to explain why these challenges remain intractable.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

Integrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

P4s Are Either Unhelpful or Unnecessary. Proposing a Better AI‐Powered Solution to Predict Patients' Preferences

Bioethics, EarlyView.
ABSTRACT The Personalized Patient Preference Predictor (P4) has been proposed as an AI tool to aid surrogate decision‐making when incapacitated patients lack advance directives. Unlike population‐level Patient Preference Predictors (PPPs), which infer preferences from demographic correlations, P4s fine‐tune large language models (LLMs) on a patient's ...

Contacting of Bicomponent TPU-Fibers with a Conductive Core: A Method for Data Acquisition and Analysis of the Electrical Properties

Fibers
With the megatrend of digitalization, the demand for sensors in previously difficult-to-access scenarios is increasing. Filament-shaped sensors (FSS) are ideal for this demand, especially in applications in which the monitoring of textile structures is ...
