TL;DR: The ocelli of E. imperialis could provide sensitive compass information for navigation in the rainforest and, additionally, provide cues for visual discrimination or flight control.

TL;DR: A novelty detection scheme based on well known image- and statistical analysis techniques is proposed and results show that the presented method gives superior recognition results and highlights the advantage of grating-based imaging.

TL;DR: Application of SAXS/WAXS provides valuable information on bone nanostructure and its constituents, effects of diseases and, prospectively, mechanical competence.

TL;DR: In this article, the first grating-based multimodal tomosynthesis images of a human breast slice acquired at a compact light source (CLS) were acquired to investigate the possibilities of improved breast cancer diagnostics.
Abstract: While the performance of conventional x-ray tube sources often suffers from the broad polychromatic spectrum, synchrotrons that could provide highly brilliant x-rays are restricted to large research facilities and impose high investment and maintenance costs. Lately, a new type of compact synchrotron sources has been investigated. These compact light sources (CLS) based on inverse Compton scattering provide quasi-monochromatic hard x-rays. The flux and brilliance yielded by a CLS currently lie between x-ray tube sources and third-generation synchrotrons. The relatively large partially coherent x-ray beam is well suited for the investigation of preclinical applications of grating-based phase-contrast and dark-field imaging. Here we present the first grating-based multimodal tomosynthesis images of a human breast slice acquired at a CLS to investigate the possibilities of improved breast cancer diagnostics.

TL;DR: In this paper, the adsorption geometry of benzoate (C6H5COO]−) on rutile-TiO2(110) was investigated.
Abstract: Scanned-energy mode photoelectron diffraction (PhD) and ab initio density functional theory calculations have been employed to investigate the adsorption geometry of benzoate ([C6H5COO]−) on rutile-TiO2(110)(1 × 1). PhD data indicate that the benzoate moiety binds to the surface through both of its oxygen atoms to two adjacent fivefold surface titanium atoms in an essentially upright geometry. Moreover, its phenyl (C6H5−) and carboxylate ([−COO]−) groups are determined to be coplanar, being aligned along the [001] azimuth. This experimental result is consistent with the benzoate geometry emerging from DFT calculations conducted for laterally rather well-separated adsorbates. At shorter interadsorbate distances, the theoretical modeling predicts a more tilted and twisted adsorption geometry, where the phenyl and carboxylate groups are no longer coplanar; i.e., interadsorbate interactions influence the configuration of adsorbed benzoate.

TL;DR: This first study of tumour tissue has not yet demonstrated that 14C bomb-pulse dating can obtain information on the growth of breast cancer, but with further refinement, involving extraction of cell types and components, there is a possibility that fundamental knowledge of tumours biology might still be gained by the bomb-Pulse technique.
Abstract: The purpose of this study was to perform an initial investigation of the possibility to determine breast cancer growth rate with (14)C bomb-pulse dating. Tissues from 11 breast cancers, diagnosed in 1983, were retrieved from a regional biobank. The estimated average age of the majority of the samples overlapped the year of collection (1983) within 3σ Thus, this first study of tumour tissue has not yet demonstrated that (14)C bomb-pulse dating can obtain information on the growth of breast cancer. However, with further refinement, involving extraction of cell types and components, there is a possibility that fundamental knowledge of tumour biology might still be gained by the bomb-pulse technique. Additionally, δ (13)C and δ (15)N analyses were performed to obtain dietary and metabolic information, and to serve as a base for improvement of the age determination.

Abstract: Introduktion til en ambitiøs dansk idé Ideen til SDC opstod på dansk side i 2007 og udsprang fra en erkendelse af Kinas voksende betydning i »videns-økonomien«. SDC skulle dels levere højtuddannet arbejdskraft med tværkulturelle kompetencer til danske virksomheder i Kina; dels styrke de videnskabelige og kommercielle relationer mellem Danmark og Kina. Den danske interesse stemte godt overens med Kinas forskningsog uddannelsespolitiske satsninger, der bl.a. fokuserede på internationalisering som et centralt element i udviklingen af kinesiske universiteter.
