The Stagger-grid: A grid of 3D stellar atmosphere models - V. Fe line shapes, shifts and asymmetries [PDF]

open access: yes, 2014
We present a theoretical study of the effects and signatures of realistic velocity field and atmospheric inhomogeneities associated with convective motions at the surface of cool late-type stars on the emergent profiles of iron spectral lines for a large

Performance Characteristics of Anti‐Collagen II Antibodies in Relapsing Polychondritis and Related Diseases: Prospective Analysis, Systematic Review, and Meta‐Analysis

open access: yesArthritis Care &Research, Accepted Article.
Background Relapsing polychondritis (RP) is a rare disease defined by recurrent cartilaginous inflammation. Anti‐collagen II (anti‐Col2) antibodies have been proposed as a diagnostic biomarker for RP, but their performance characteristics are not well defined.

A three-dimensional statistical shape model of the growing mandible

open access: yesScientific Reports, 2021
Mandibular growth and morphology are important topics in the field of oral and maxillofacial surgery. For diagnostic and planning purposes, a normative database or statistical shape model of the growing mandible can be of great benefit.

Robot‐Assisted Automated Serial‐Sectioning and Imaging for 3D Microstructural Investigations

open access: yesAdvanced Engineering Materials, EarlyView.
A fully automated 3D microstructure characterization platform provides new insights into materials. This robot‐assisted system performs serial‐sectioning, etching, and optical imaging to generate large‐volume 3D reconstructions with submicron resolution.

Serbian bioethics from an international perspective: Genetics and bioethics [PDF]

open access: yesFilozofija i Društvo, 2012
Global interests in bioethics have increased drastically since the end of 20th century. The reason for this should be ascribed to a broad application of molecular-genetic methods introduced in human bio-medicine.

Scientific Highlights from Observations of Active Galactic Nuclei with the MAGIC Telescope

open access: yes, 2008
Since 2004, the MAGIC gamma-ray telescope has newly discovered 6 TeV blazars. The total set of 13 MAGIC-detected active galactic nuclei includes well-studied objects at other wavelengths like Markarian 501 and the giant radio galaxy M87, but also the ...

Ionic Control of Microstructure and Lubrication in Charged, Physically Cross‐Linked Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
Here, charged, physically cross‐linked poly(methacrylamide‐co‐methacrylic acid) hydrogels stabilized by a short‐range attractive, long‐range repulsive potential is investigated. This work uncovers how salt addition alters not only swelling, but also the microstructure and dynamics, near‐surface stiffness and charge, and ultimately, its lubricity. Salts

Generative Adversarial Networks and Data Clustering for Likable Drone Design

open access: yesSensors, 2022
Novel applications for human-drone interaction demand new design approaches, such as social drones that need to be perceived as likable by users. However, given the complexity of the likability perception process, gathering such design information from ...

Magnetic sublevel independent magic wavelengths: Application in the Rb and Cs atoms

open access: yes, 2016
A generic scheme to trap atoms at the magic wavelengths ($\lambda_{\rm{magic}}$s) that are independent of vector and tensor components of the interactions of the atoms with the external electric field is presented.

Geometrically Templated, Ultra‐Lightweight and High Strength Soap Films from Lyotropic Liquid Crystalline Graphene Oxide/Polymer Composites

open access: yesAdvanced Functional Materials, EarlyView.
Shellular materials form spontaneously by dip coating the primitive triply periodic minimal surface (TPMS) wireframe in an aqueous solution of lyotropic liquid crystalline graphene oxide (GO) nanosheets mixed with polymers. Regulated by surface tension, GO nanosheets align on the polymer soap film as the stress builds up during drying.
