Soils in Arctic and boreal ecosystems store twice as much carbon as the atmosphere, a portion of which may be released as high-latitude soils warm. Some of the uncertainty in the timing and magnitude of the permafrost-climate feedback stems from complex interactions between ecosystem properties and soil thermal dynamics. Terrestrial ecosystems fundamentally regulate the response of permafrost to c

Background: Hyperuricemia (HU) is in the causal pathway for developing clinical gout. There are few population-based assessments of the absolute and relative risk of clinically diagnosed incident gout in subjects with HU. We aimed to explore the long-term risk of developing incident gout among asymptomatic adults with different levels of serum urate (SU). Methods: Malmö Preventive Project was a po

This paper provides empirical evidence in support of the clash-of-civilizations view on the nature of interstate conflicts in the post-Cold War era. First, we show that countries belonging to different civilizations have a higher probability of interstate conflict before and after the Cold War period, but not during the Cold War. Second, we explain the differential impact of civilizations on confl

This paper examines the role of ethnic minorities in bilateral trade between countries of the ex‐Soviet Union. We argue that both forced re‐settlement of entire ethnic groups during the Stalin era and artificially drawn borders in Central Asia led to an exogenous ethnic composition within countries. Using data collected by ethnologists on the share of ethnic groups across countries, we build an in

This paper assesses the effect of the Russo–Georgian conflict of 2008 and the Ukrainian–Russian conflict of 2014 on the well-being of minorities in Russia. Using the Russian Longitudinal Monitoring Survey (RLMS), we find that the well-being of Georgians in Russia suffered negatively from the 2008 Russo–Georgian conflict. We show that the conflict has no direct effect on the labor market outcomes o

The determinants of countries' long‐term income differences feature prominently in the literature. Spolaore and Wacziarg (The diffusion of development, Quarterly Journal of Economics, 2009, 124, 469–529) argue that cultural differences, measured by countries' genetic distance, are an important barrier to the diffusion of development from the world's technological frontier. We revisit their finding

This paper studies the Clash of Civilizations hypothesis from an economic perspective. Using data on bilateral trade and measures of culture, we evaluate how the impact of cultural differences on trade evolves over time during and after the Cold War. Evidence suggests that the negative influence of cultural differences on trade is more prominent in the post-Cold War era than during the Cold War. F

De senaste årens fokus på säkerhetsrisker i samhället har gett upphov till olika former av polisarbete, såsom gränsöverskridande och underrättelsebaserat polisarbete. Den här studien uppmärksammar ett samverkansprojekt mellan gränsmyndigheter i Östersjöområdet som pågick mellan 2014 och 2015. Projektet fick namnet Turnstone och involverade underrättelsepoliser, gränspoliser och kustbevakare från SThe risks and insecurities emphasised in contemporary societies have given rise to diverse forms of policing, such as transnational and intelligence-based police collaborations. This dissertation focuses on a border police collaboration project, called Turnstone, that took place between 2014 and 2015, aiming to address issues related to irregular migration and cross border crimes in the Baltic Sea

In this paper, we propose a novel 1-D spectralestimator for signals with mixed spectra. The proposed methodis partly based on the recently introduced smooth spectralestimator LIMES, in which the smoothness is accounted for byassuming linearity within predefined segments of the spectrum.The proposed method utilizes this formulation but also allowssegments to change size to better estimate the spect

In this paper we calculate reassigned spectrogramsusing the envelope of an arbitrary signal as matched window. Weshow that the matched window then give the perfectly localizedreassignment for any time-translated and frequency-modulatedtransient signal with corresponding envelope. The general expressions of the corresponding scaled reassignment vectors arederived and the matched window reassignment

BACKGROUND: Metformin is the most common pharmacological treatment for type 2 diabetes. It is considered safe but has been associated with the development of lactic acidosis under circumstances where plasma concentrations exceed therapeutic levels. Metformin-induced lactic acidosis has been linked to the drug's toxic effect on mitochondrial function. Current treatment strategies aim to remove the

Eye movements have been extensively studied in a wide range of research fields. While new methods such as mobile eye tracking and eye tracking in virtual/augmented realities are emerging quickly, the eye-movement terminology has scarcely been revised. We assert that this may cause confusion about two of the main concepts: fixations and saccades. In this study, we assessed the definitions of fixati
