Simultaneous harvest-and-transmit ambient backscatter communications under Rayleigh fading
2019
Ambient backscatter communications is an emerging paradigm and a key enabler for pervasive connectivity of low-powered wireless devices. It is primarily beneficial in the Internet of things (IoT) and the situations where computing and connectivity capabilities expand to sensors and miniature devices that exchange data on a low power budget. The premise of the ambient backscatter communication is to build a network of devices capable of operating in a battery-free manner by means of smart networking, radio frequency (RF) energy harvesting and power management at the granularity of individual bits and instructions. Due to this innovation in communication methods, it is essential to investigat…
Buddhism as “creator” of transnational social support ties? Experiencing spirituality in a Tibetan child care organization in exile and its meaning f…
2014
The influence of Buddhism on transnational social support ties has not been researched systematically from an empirical angle until recently. In this article I delve into the support structures of a Tibetan community-based child care organization and its donors from western countries, and emerge with an understanding of how religious belonging and spiritual experiences contribute to the formation of transnational social support ties. By introducing religion that transcends national borders, in this instance, Tibetan Buddhism, as a category for analyzing transnational social support ties, I broaden the understanding of how diaspora is formed, for I look not only at Tibetans in diaspora, but …
Cluster Origin of Solvent Features of Fullerenes, Single-Wall Carbon Nanotubes, Nanocones, and Nanohorns
2014
This chapter discusses the existence of single-wall carbon nanocones (SWNCs), especially nanohorns (SWNHs) in organic solvents in the form of clusters. A theory is developed based on a bundlet model describing their distribution function by size. Phenomena have a unified explanation in bundlet model in which free energy of an SWNC, involved in a cluster, is combined from two components: a volume one, proportional to number of molecules n in a cluster, and a surface one proportional to n1/2. A bundlet model enables describing distribution function of SWNC clusters by size. From purely geometrical differences, bundlet (SWNCs) and droplet (fullerene) models predict different behaviours. The SW…
Steam and gas emission rate from La Soufriere volcano, Guadeloupe (Lesser Antilles): implications for the magmatic and hydrothermal fluid supply duri…
2014
Since its last magmatic eruption in 1530 AD, La Soufrière andesitic volcano in Guadeloupe has displayed intense hydrothermal activity and six phreatic eruptive crises. Here we report on the first direct quantification of gas plume emissions from its summit vents,which gradually intensified during the past 20 years. Gas fluxes were determined in March 2006 and March 2012 by measuring the horizontal and vertical distributions of volcanic gas concentrations in the air-diluted plume and scaling to the speed of plume transport. Fluxes in 2006 combine realtime measurements of volcanic H2S concentrations and plume parameters with the composition of the hot (108.5 °C) fumarolic fluid at exit. Fluxe…
The Effect of Tiotropium in Symptomatic Asthma Despite Low- to Medium-Dose Inhaled Corticosteroids: A Randomized Controlled Trial.
2014
BackgroundTiotropium, a once-daily long-acting anticholinergic bronchodilator, has demonstrated efficacy in patients with asthma who were symptomatic despite treatment with medium- to high-dose inhaled corticosteroids (ICS).ObjectiveThe objective of this study was to evaluate the efficacy and safety of once-daily tiotropium Respimat (5 μg or 2.5 μg), compared with placebo Respimat, as add-on therapy to low- to medium-dose ICS for adults with symptomatic asthma.MethodsA phase III, double-blind, placebo-controlled trial was conducted (NCT01316380). Adults with symptomatic asthma receiving low- to medium-dose ICS (200-400 μg budesonide or equivalent dose) and a pre-bronchodilator forced expira…
3D Morphology, ultrastructure and development of Ceratomyxa puntazzi stages: first insights into the mechanisms of motility and budding in the Myxozo…
2012
Free, amoeboid movement of organisms within media as well as substrate-dependent cellular crawling processes of cells and organisms require an actin cytoskeleton. This system is also involved in the cytokinetic processes of all eukaryotic cells. Myxozoan parasites are known for the disease they cause in economical important fishes. Usually, their pathology is related to rapid proliferation in the host. However, the sequences of their development are still poorly understood, especially with regard to pre-sporogonic proliferation mechanisms. The present work employs light microscopy (LM), electron microscopy (SEM, TEM) and confocal laser scanning microscopy (CLSM) in combination with specific…
A New Method for the Price Determination of the Reactive Power Supply
2006
This paper addresses the development of an accurate model for the pricing of reactive power supply as an ancillary service. Reactive power supply is one of the most important ancillary services in the field of transmission systems security. The present work is focused on building a reactive power market at which the Distributors can also take part in injecting reactive power at the connected HV/MV nodes. The authors have studied the particular case of the reactive power supplied by sub-transmission or distribution networks, connected to the nodes of the transmission system. The aim of this work is to establish a reactive power price by crossing demand and offer curves.
Liquidity-adjusted value-at-risk optimization of a multi-asset portfolio using a vine copula approach
2019
Abstract This paper develops a novel approach to assess liquidity-adjusted Value-at-Risk (LVaR) optimization of multi-asset portfolios based on vine copulas and LVaR models. This framework is applied to stock markets of the G-7 countries, gold, commodities and Bitcoin. The results show that our approach is superior to the classical mean–variance Markowitz portfolio technique in terms of the optimal portfolio selection under a number of realistic operational and budget constraints. We find that both Bitcoin and gold improves the risk-return performance of the G-7 stock portfolio. However, Bitcoin (gold) performs better under a scenario of only long-positions (when short-selling is allowed).
New Alliances in Post-Brexit Europe: Does the New Hanseatic League Revive Nordic Political Cooperation?
2020
As Brexit removes the Nordic countries’ most powerful ally from the EU, what does this imply for their approach to European affairs? The literature on small states within the EU suggests that they can counterbalance limited bargaining capacities by entering two types of alliances: strategic partnerships with bigger member states and institutionalised cooperation on a regional basis. Against this backdrop we ask whether, by significantly raising the costs of non-cooperation for Nordic governments, the Brexit referendum has triggered a revival of Nordic political cooperation. We scrutinise this conjecture by analysing Nordic strategies of coalition-building on EU financial and budgetary polic…
FISCAL STATE POLICY FOR SUSTAINABLE DEVELOPMENT
2011
One of the most important measures to be taken for the development of sustainable economy in Latvia is to implement an effective fiscal policy. It means a complex and well timed use of fiscal instruments to regulate economy. Evaluating the proposals of the government and the measures taken for the stabilization of economy we can make the conclusion that they have not always been effective and economically justified. Several rearrangements in the field of planning taxes and budget have been late. The aim of the article is on the basis of the theoretical viewpoints, to undertake a critical assessment of the fiscal measures taken by the government of Latvia and to make recommendations for the …
