Stellar Ages for Galactic Archaeology : Methods and Applications

Galactic Archaeology is the study of the formation and evolution of the Milky Way through the properties of stars and stellar populations. The combination of stellar ages, chemical compositions, positions, and velocities can reveal the history of star formation and chemical enrichment in different regions of the Galaxy. A large number of stellar spectroscopic, photometric, and astrometric surveys

Open Data Ecosystems - an empirical investigation into an emerging industry collaboration concept

Software systems are increasingly depending on data, particularly with the rising use of machine learning, and developers are looking for new sources of data. Open Data Ecosystems (ODE) is an emerging concept for data sharing under public licenses in software ecosystems, similar to Open Source Software (OSS). It has certain similarities to Open Government Data (OGD), where public agencies share da

The Car-Emissions Investigation: Goals of Antitrust and the Protection of the Federal Regulators Authority : Some thoughts form the other side of the pond

This paper explores the US antitrust investigation into commitment by Ford, Honda, BMW and Volkswagen to comply with emission standards set out by the state of California from an EU perspective. It takes a look at the DOJ’s investigation and explores how such a case would be handled under the EU’s legal framework. First, it briefly provides the background of the U.S. case, including some political

KATANIN and CLASP function at different spatial scales to mediate microtubule response to mechanical stress in Arabidopsis cotyledons

Mechanical stress influences cell- and tissue-scale processes across all kingdoms. It remains challenging to delineate how mechanical stress, originating at these different length scales, impacts cell and tissue form. We combine growth tracking of cells, quantitative image analysis, as well as molecular and mechanical perturbations to address this problem in pavement cells of Arabidopsis thaliana

The Egyptian broadcasting sector between 1920 and 2020

The chapter provides a brief overview of the development of the broadcasting sector in Egypt, demonstrating the significance of this sector in promoting the ideologies and policies of Egypt’s successive regimes, beginning with Nasser’s through al-Sisi’s governments. Although the sector was subjected to liberalization, under Mubarak’s rule, state television still dominated the broadcasting sector a

Digital health technology for non-motor symptoms in people with Parkinson's disease : Futile or future?

Introduction: There is an ongoing digital revolution in the field of Parkinson's disease (PD) for the objective measurement of motor aspects, to be used in clinical trials and possibly support therapeutic choices. The focus of remote technologies is now also slowly shifting towards the broad but more “hidden” spectrum of non-motor symptoms (NMS). Methods: A narrative review of digital health techn

Systematic evaluation of SARS-CoV-2 antigens enables a highly specific and sensitive multiplex serological COVID-19 assay

Objective: The COVID-19 pandemic poses an immense need for accurate, sensitive and high-throughput clinical tests, and serological assays are needed for both overarching epidemiological studies and evaluating vaccines. Here, we present the development and validation of a high-throughput multiplex bead-based serological assay. Methods: More than 100 representations of SARS-CoV-2 proteins were inclu

Valence shell photoelectron angular distributions and vibrationally resolved spectra of imidazole : A combined experimental-theoretical study

Linearly polarized synchrotron radiation has been used to record polarization dependent valence shell photoelectron spectra of imidazole in the photon energy range 21-100 eV. These have allowed the photoelectron angular distributions, as characterized by the anisotropy parameter β, and the electronic state intensity branching ratios to be determined. Complementing these experimental data, theoreti

Pediatric procedural sedation and analgesia in the emergency department : surveying the current European practice

Procedural sedation and analgesia outside the operating theater have become standard care in managing pain and anxiety in children undergoing diagnostic and therapeutic procedures. The objectives of this study are to describe the current pediatric procedural sedation and analgesia practice patterns in European emergency departments, to perform a needs assessment-like analysis, and to identify barr

Kala-azar outbreak in Libo Kemkem, Ethiopia : epidemiologic and parasitologic assessment

In May 2005, visceral leishmaniasis (VL) was recognized for the first time in Libo Kemkem, Ethiopia. In October 2005, a rapid assessment was conducted using data from 492 patients with VL treated in the district health center and a household survey of 584 residents of four villages. One subdistrict accounted for 71% of early cases, but the incidence and number of affected subdistricts increased pr

Epidemiology and clinical features of patients with visceral leishmaniasis treated by an MSF clinic in Bakool region, Somalia, 2004-2006

BACKGROUND: There are few reports describing the epidemiology of visceral leishmaniasis (VL) in Somalia. Over the years 2002 to 2005, a yearly average of 140 patients were reported from the Huddur centre in Bakool region, whereas in 2006, this number rose to 1002 patients. Given the limited amount of information on VL and the opportunity to compare features with the studies done in 2000 in this pa

Natural history of a visceral leishmaniasis outbreak in highland Ethiopia

In May 2005, visceral leishmaniasis (VL) was recognized for the first time in Libo Kemken, Ethiopia, a highland region where only few cases had been reported before. We analyzed records of VL patients treated from May 25, 2005 to December 13, 2007 by the only VL treatment center in the area, maintained by Médecins Sans Frontières-Ethiopia, Operational Center Barcelona-Athens. The median age was 18

“Omics” in traumatic brain injury : novel approaches to a complex disease

Background: To date, there is neither any pharmacological treatment with efficacy in traumatic brain injury (TBI) nor any method to halt the disease progress. This is due to an incomplete understanding of the vast complexity of the biological cascades and failure to appreciate the diversity of secondary injury mechanisms in TBI. In recent years, techniques for high-throughput characterization and
