Commemorating a war that never came : The Cold War as counter-factual war memory

The Cold War never became the global World War III. It was a war that never broke out. Nevertheless, in some countries like for instance Denmark it is commemorated as exactly that: a war. This is particularly apparent at museums and heritage sites, where the narrative and mnemonic frame works used and activated in the representations stem from cultural memories of the Second World War. In the proc

Globally Optimal Relative Pose Estimation with Gravity Prior

Smartphones, tablets and camera systems used, e.g., in cars and UAVs, are typically equipped with IMUs (inertial measurement units) that can measure the gravity vector accurately. Using this additional information, the y-axes of the cameras can be aligned, reducing their relative orientation to a single degree-of-freedom. With this assumption, we propose a novel globally optimal solver, minimizing

Modesty as a Condition for Circular Economy Transition Success

Modesty as a Condition for Circular Economy Transition SuccessThe Promise and Challenges of a Circular Economy TransitionThe circular economy offers much promise. Circularity is meant to be a pathway to material efficiency, energy transitions, green jobs, profitable business opportunities, reduced volatility in price of inputs, secured supplies of critical materials, increased customer experiences

Homography-Based Minimal-Case Relative Pose Estimation With Known Gravity Direction

In this paper, we propose a novel approach to two-view minimal-case relative pose problems based on homography with known gravity direction. This case is relevant to smart phones, tablets, and other camera-IMU (Inertial measurement unit) systems which have accelerometers to measure the gravity vector. We explore the rank-1 constraint on the difference between the euclidean homography matrix and th

Minimal Solutions to Relative Pose Estimation From Two Views Sharing a Common Direction With Unknown Focal Length

We propose minimal solutions to relative pose estimation problem from two views sharing a common direction with unknown focal length. This is relevant for cameras equipped with an IMU (inertial measurement unit), e.g., smart phones, tablets. Similar to the 6-point algorithm for two cameras with unknown but equal focal lengths and 7-point algorithm for two cameras with different and unknown focal l

An Efficient Solution to the Homography-Based Relative Pose Problem With a Common Reference Direction

In this paper, we propose a novel approach to two-view minimal-case relative pose problems based on homography with a common reference direction. We explore the rank-1 constraint on the difference between the Euclidean homography matrix and the corresponding rotation, and propose an efficient two-step solution for solving both the calibrated and partially calibrated (unknown focal length) problems

Analyzing Disparity and Rates of Morphological Evolution with Model-Based Phylogenetic Comparative Methods

Understanding variation in rates of evolution and morphological disparity is a goal of macroevolutionary research. In a phylogenetic comparative methods framework, we present three explicit models for linking the rate of evolution of a trait to the state of another evolving trait. This allows testing hypotheses about causal influences on rates of phenotypic evolution with phylogenetic comparative

Performance evaluation of IMERG and TMPA daily precipitation products over CONUS (2000–2019)

Ground validation of satellite-based precipitation products is necessary to evaluate the performance of satellite observation at local, regional, and global scales. The evaluation of the rainfall data accuracy will reveal both its strengths and weaknesses, thereby determining its suitability for hydrometeorological applications. To reach this goal, this study comprehensively evaluated and characte

Cohort profile : the Halland osteoarthritis (HALLOA) cohort-from knee pain to osteoarthritis: a longitudinal observational study in Sweden

Purpose The overall objective in this study is to investigate the early development of radiographic knee osteoarthritis (OA) and its association with hand or/and knee OA, metabolic diseases, biomarkers, chronic pain, physical function and daily physical activity types. Participants The Halland osteoarthritis (HALLOA) cohort is a longitudinal cohort study that includes individuals with knee pain in

Association of Blood Pressure with Prostate Cancer Risk by Disease Severity and Prostate Cancer Death : A Pooled Cohort Study

Background: The association of blood pressure (BP) with prostate cancer risk after accounting for asymptomatic prostate-specific antigen (PSA) testing, and with prostate cancer death, is unclear. Methods: We investigated BP, measured at a mean age of 38 years among 430,472 men from five Swedish cohorts, in association with incident prostate cancer (n = 32,720) and prostate cancer death (n = 6718).

An interrupted time series analysis of gambling behavior based on gambling operator revenue-based taxation during the COVID-19 pandemic in Sweden

Objectives: The impact of COVID-19 on gambling behavior and the gambling industry itself has been widely speculated. Prior studies have shown how boredom, social isolation, poor mental health, and financial hardships, all of which have been associated with COVID-19, can aggravate problem gambling behaviors in patients with gambling disorders while also luring newcomers. Few studies have used metho

The EEAS navigating foreign policy paradigms

Addressing the issue of EU foreign policy, this article analyses one of the European institutions, the EEAS, and examines how the EEAS navigates in a European landscape characterised by a handful of main foreign policy paradigms. In particular, we ask how the EEAS has adjusted its foreign policies in the light of competing paradigms. In the first section, we explicate the key concepts including po

Globalisation in reverse? Reconfiguring the geographies of value chains and production networks

Standing at a crossroads, where ongoing 'slowbalisation' coincides with new forces such as the outbreak of the Covid-19 pandemic, heightened geopolitical tensions, the emergence of disruptive technologies and the increasing urgency of addressing environmental challenges, many important questions remain unsolved regarding the nature and impact of the current economic globalisation. This special iss

Sympathizing With the Radical Right : Effects of Mainstream Party Recognition and Control of Prejudice

The electoral success of radical right parties throughout Western Europe is the biggest change to these formerly stable party systems. Several studies have identified that mainstream parties can shape the trajectory of radical right parties. Our aim is to contribute to this literature, and to investigate if and how radical right parties gain from mainstream party recognition. Theoretically, we dra

Growth after the streaming instability : The radial distance dependence of the planetary growth

Streaming instability is hypothesized to be triggered at particular protoplanetary disk locations where the volume density of the solid particles is enriched comparable to that of the gas. A ring of planetesimals thus forms when this condition is fulfilled locally. These planetesimals collide with each other and accrete inward drifting pebbles from the outer disk to further increase masses. We inv
