A novel change detection approach based on visual saliency and random forest from multi-temporal high-resolution remote-sensing images
This article presents a novel change detection (CD) approach for high-resolution remote-sensing images, which incorporates visual saliency and random forest (RF). First, highly homogeneous and compact image super-pixels are generated using super-pixel segmentation, and the optimal segmentation result is obtained through image superimposition and principal component analysis. Second, saliency detec
Disaster Exercises to Prepare Hospitals for Mass-Casualty Incidents : Does it Contribute to Preparedness or is it Ritualism?
Introduction: The central question this study sought to answer was whether the team members of Strategic Crisis Teams (SCTs) participating in mass-casualty incident (MCI) exercises in the Netherlands learn from their participation. Methods: Evaluation reports of exercises that took place at two different times were collected and analyzed against a theoretical model with several dimensions, looking
Shill Bidding and Information in Sequential Auctions: A Laboratory Study
Second-price auctions with public information, such as those on eBay, provide an opportunity for sellers to use the information from finished and ongoing auctions when acting strategically in future auctions. Sellers have frequently been observed to bidding on their own item with the intent to artificially increase its price. This is known as shill bidding. Using lab experiments with two sequentia
A quantum-dot heat engine operating close to the thermodynamic efficiency limits
Cyclical heat engines are a paradigm of classical thermodynamics, but are impractical for miniaturization because they rely on moving parts. A more recent concept is particle-exchange (PE) heat engines, which uses energy filtering to control a thermally driven particle flow between two heat reservoirs1,2. As they do not require moving parts and can be realized in solid-state materials, they are su
Two sides of the same coin : The experiences of high-achieving women in the Swedish workplace
Adopting a qualitative approach to the investigation of high achievement, the authors analyzed how high-achieving women in the Swedish workplace made meaning of positive and negative experiences in their work. The data consisted of interviews with 15 women identified as being high achieving in their respective field, and it was analyzed using grounded theory methodology. The women described five d
Relationship between Hydrogen-Atom Transfer Driving Force and Reaction Rates for an Oxomanganese(IV) Adduct
Hydrogen atom transfer (HAT) reactions by high-valent metal-oxo intermediates are important in both biological and synthetic systems. While the HAT reactivity of FeIV-oxo adducts has been extensively investigated, studies of analogous MnIV-oxo systems are less common. There are several recent reports of MnIV-oxo complexes, supported by neutral pentadentate ligands, capable of cleaving strong C-H b
Gale's Fixed Tax for Exchanging Houses
We consider the taxation of exchanges among a set of agents where each agent owns one object. Agents may have different valuations for the objects and they need to pay taxes for exchanges. Using basic properties, we show that if pairwise (or some) exchanges of objects are allowed, then all exchanges (in any possible manner) must be feasible. Furthermore, whenever any agent exchanges his object, he
Older assistant nurses’ motivation for a full or extended working life
The aim of this study was to explore older workers’ motivation for a full or extended working life. With particular focus on assistant nurses aged 55–64 years, working in the elderly care sector. Focus group interviews were conducted with five different groups of assistant nurses. Inductive thematic analysis was used to analyse the interviews and five main themes were developed from the data: ‘Org
The global biogeography of avian haemosporidian parasites is characterized by local diversification and intercontinental dispersal
The biogeographic histories of parasites and pathogens are infrequently compared with those of free-living species, including their hosts. Documenting the frequency with which parasites and pathogens disperse across geographic regions contributes to understanding not only their evolution, but also the likelihood that they may become emerging infectious diseases. Haemosporidian parasites of birds (
Human bone marrow-derived myeloid dendritic cells show an immature transcriptional and functional profile compared to their peripheral blood counterparts and separate from slan+ non-classical monocytes
The human bone marrow (BM) gives rise to all distinct blood cell lineages, including CD1c+ (cDC2) and CD141+ (cDC1) myeloid dendritic cells (DC) and monocytes. These cell subsets are also present in peripheral blood (PB) and lymphoid tissues. However, the difference between the BM and PB compartment in terms of differentiation state and immunological role of DC is not yet known. The BM may represe
Patchy field sampling biases understanding of climate change impacts across the Arctic
Effective societal responses to rapid climate change in the Arctic rely on an accurate representation of region-specific ecosystem properties and processes. However, this is limited by the scarcity and patchy distribution of field measurements. Here, we use a comprehensive, geo-referenced database of primary field measurements in 1,840 published studies across the Arctic to identify statistically
Poly(arylene alkylene)s with pendant N-spirocyclic quaternary ammonium cations for anion exchange membranes
Aromatic polymers functionalised with cycloaliphatic quaternary ammonium (QA) cations are currently emerging as base stable anion exchange membranes (AEMs) for use in alkaline fuel cells and water electrolyzers. In the present work we have first prepared poly(biphenyl piperidine)s in superacid-mediated polycondensations, and then introduced different N-spirocyclic QA cations via cyclo-quaternisati
Bruton’s tyrosine kinase potentiates ALK signaling and serves as a potential therapeutic target of neuroblastoma
Aberrant activation of anaplastic lymphoma kinase (ALK) can cause sporadic and familial neuroblastoma. Using a proteomics approach, we identified Bruton’s tyrosine kinase (BTK) as a novel ALK interaction partner, and the physical interaction was confirmed by co-immunoprecipitation. BTK is expressed in neuroblastoma cell lines and tumor tissues. Its high expression correlates with poor relapse-free
The International Encyklopedia of Strategic Communication , Vol 1-3
The term "strategic communication" traditionally has been understood as referring to external corporate communication, such as public relations, marketing communication, and advertising, with insufficient consideration beyond its role as a tool of persuasive influence. In recent years, however, the field of strategic communication has evolved to be more holistic in its approach and its role within
Fetal gene therapy for neurodegenerative disease of infants
For inherited genetic diseases, fetal gene therapy offers the potential of prophylaxis against early, irreversible and lethal pathological change. To explore this, we studied neuronopathic Gaucher disease (nGD), caused by mutations in GBA. In adult patients, the milder form presents with hepatomegaly, splenomegaly and occasional lung and bone disease; this is managed, symptomatically, by enzyme re

Shedding Light on the Nature of Photoinduced States Formed in a Hydrogen-Generating Supramolecular RuPt Photocatalyst by Ultrafast Spectroscopy
Photoinduced electronic and structural changes of a hydrogen-generating supramolecular RuPt photocatalyst are studied by a combination of time-resolved photoluminescence, optical transient absorption, and X-ray absorption spectroscopy. This work uses the element specificity of X-ray techniques to focus on the interplay between the photophysical and -chemical processes and the associated time scale
