Desertification-A global monitoring approach

This paper presents the first results of an ongoing study on the use of the NOAA AVHRR based GIMMS 8 km global NDVI data set (1981-2004) for desertification monitoring. Our monitoring and assessment was carried out on a regional-global scale. Time series of NDVI and standardized annual NDVI anomalies (1981-2004) were compared with corresponding 0.5 degrees spatial resolution gridded annual rainfal

Perceptions of the European Union's Fledgling Delegations: More Coherence, More Effectiveness?

The debate surrounding the challenge of improving coherence in European Union (EU) foreign policy is ongoing. EU Delegations (EUDs), operating under the European External Action Service (EEAS) were recently established to provide a focal point for the EU in third countries, providing potential for improving EU coherence. Using the case study of the EUDs, this article adds to theorizations of EU co

Similar estimates of temperature impacts on global wheat yield by three independent methods

The potential impact of global temperature change on global crop yield has recently been assessed with different methods. Here we show that grid-based and point-based simulations and statistical regressions (from historic records), without deliberate adaptation or CO 2 fertilization effects, produce similar estimates of temperature impact on wheat yields at global and national scales. With a 1 °C

The GAGOme : a cell-based library of displayed glycosaminoglycans

Glycosaminoglycans (GAGs) are essential polysaccharides in normal physiology and disease. However, understanding of the contribution of specific GAG structures to specific biological functions is limited, largely because of the great structural heterogeneity among GAGs themselves, as well as technical limitations in the structural characterization and chemical synthesis of GAGs. Here we describe a

Industrial Intensification and Energy Embodied in Trade : Long-Run Energy Perspective of the Planned Economy of Czechoslovakia

This paper examines the role of foreign trade in the consumption of energy in Czechoslovakia through a bottom-up approach in accounting for energy embodied in trade with manufactured goods. It provides a unique analysis of annual changes in energy embodied in trade in a country characterized by changing political regimes. On the whole, Czechoslovakia has been a net exporter of energy throughout th

Medium-term heat load prediction for an existing residential building based on a wireless on-off control system

For district heating systems, prediction of the heat load is a very important topic for energy storage and optimized operation. For large and complex heating systems, most prediction models in previous publications only considered the influence of outdoor temperature, whereas the indoor temperature and thermal inertia of buildings were not included. For an energy-efficient residential building in

Global area boom for greenhouse cultivation revealed by satellite mapping

Greenhouse cultivation has been expanding rapidly in recent years, yet little knowledge exists on its global extent and expansion. Using commercial and freely available satellite data combined with artificial intelligence techniques, we present a global assessment of greenhouse cultivation coverage and map 1.3 million hectares of greenhouse infrastructures in 2019, a much larger extent than previo

Allocation of ecological water rights considering ecological networks in arid watersheds : A framework and case study of Tarim River basin

A robust water supply system is significant to the local ecosystem of riparian vegetation in the arid basin. Considering the elasticity and relative importance of ecological water use in different regions of the basin, this study defines the ecological water rights on a multi-year scale, divides the priority of those rights based on the ecological network, and proposes a rights allocation method.

Musculature of an Early Cambrian cycloneuralian animal

Cycloneuralians are ecdysozoans with a fossil record extending to the Early Cambrian Fortunian Age and represented mostly by cuticular integuments. However, internal anatomies of Fortunian cycloneuralians are virtually unknown, hampering our understanding of their functional morphology and phylogenetic relationships. Here we report the exceptional preservation of cycloneuralian introvert musculatu

Combination and summary of ATLAS dark matter searches interpreted in a 2HDM with a pseudo-scalar mediator using 139 fb−1 of s=13 TeV pp collision data

Results from a wide range of searches targeting different experimental signatures with and without missing transverse momentum (ETmiss) are used to constrain a Two-Higgs-Doublet Model (2HDM) with an additional pseudo-scalar mediating the interaction between ordinary and dark matter (2HDM+a). The analyses use up to 139 fb−1 of proton–proton collision data at a centre-of-mass energy s=13 TeV recorde
