In order to develop reliable communications links for high speed railway (HSR) systems, accurate models for the propagation channel are required. The radio channel properties in HSR scenarios are different from those in cellular scenarios not only due to the high velocity, but also due to the special construction elements and the type of surroundings along the train lines. This paper focuses on th
We use Baker, Bloom, and Davis’s (2016) economic policy uncertainty indices in combination with the mixed data sampling (MIDAS) approach to investigate long-run stock market volatility and correlation, primarily for the US and UK. Long-run US–UK stock market correlation depends positively on US economic policy uncertainty shocks. The dependence is asymmetric, with only positive shocks - increasing
This paper describes our contribution to the semantic role labeling task (SRL-only) of the CoNLL-2009 shared task in the closed challenge(Hajic et al., 2009). Our system consists of a pipeline of independent, local classifiers that identify the predicate sense, the arguments of the predicates, and the argument labels. Using these local models, we carried out a beam search to generate a pool of can
Governments increasingly rely on new information and communication technology to connect with citizens. An important aspect of this e-governance is to enhance openness to empower citizens. Nonetheless, it is debated whether the digitization of government has in fact led to increased transparency, or whether governments primarily use the online interfaces to enhance social control. From a critical
History shows that wars can be enormously disruptive of economic activity, especially international trade, national income, and global economic welfare. This article analyzes the impact on the European regions the Russian invasion of Ukraine using the largest and most updated multiregional input-output model for Europe. Two shocks, trade and inflation, and four alternative scenarios are simulated.
This article is concerned with what conditions successful development of high-tech regions in developing countries. It argues that the recent regional turn in development studies should be welcomed as regions play an increasingly important role for high-tech industries in developed and developing countries. While acknowledging the insights stemming from the regional turn the article nevertheless a
An Extended Triple Collocation for maximized Correlation (ETCC) method was proposed with a unique correlation function, the purpose of which is to maximize the correlation between the merged product and unknown truth. The method was tested over quasi-global land by combining three independent precipitation products. The performance of the ETCC-merged product was then evaluated against three refere
The development of new industries in peripheral regions has gained renewed attention recently. Yet, the processes through which peripheral regions can mobilize external resources and capabilities, and turn them into locally sticky resources for structural change and longer-term economic prosperity, have not been sufficiently conceptualized. This article proposes anchoring-based regional system bui
Impulsive noise is one of the most challenging forms of interference in an underwater acoustic environment. In this paper, we present an underwater acoustic channel deconvolution method based on a sparse representation framework. The application of the method enables a channel impulse response reconstruction that is robust to impulsive noise. By exploiting the inherent structure in the channel res
Globalization has led to the emergence of global value chains (GVCs) and most of the world’s trade is now in intermediate inputs. This has raised questions about employment in GVCs and attracted the interest of researchers and policymakers alike, but is difficult to study empirically. This paper investigates job creation in simple and complex GVCs for 43 economies between 2000 and 2014 on the basi
This thesis examines the acquisition of Japanese vocabulary by Swedish L1 speakers learning Japanese as a second language, and how well their proficiency, acquired through formal education in Sweden, aligns with the Japanese Language Proficiency Test (JLPT) standards. The study also compares the recognition rates of different types of word classes such as nouns, adjectives, and verbs across variou
Taiwan is in many ways an excellent example of how an authoritarian country can overcome much of the associated difficulties of successfully transitioning into a healthy and well-functioning democracy. In spite of this undisputed fact, Taiwan can only be characterized as a diplomatic orphan, an outcast, shunned by the international community because of events dating back to before World War II and
For a few years’ time, there have been those who say that American power is declining relatively to its counterparts on the major power arena. According to Power Cycle Theory the probability of major war is highest when a major power is close to a critical point. In this paper I am testing the proposition made by the power cycle theory, that the probability of a major war is higher in a critical p
This essay describes the will of states to cooperate in organizations so that they can respond towards relative power changes between them. The focus of the essay is Russia’s interests to cooperate in Central Asia in the organization Shanghai Cooperation Organization (SCO). I use Kenneth Waltz theory about defensive realism and Robert Keohane and Joseph Nye’s theory about interdependence to descri
