The impact of the Russian war against Ukraine should have far-reaching repercussions on the teaching of International Relations (IR) and European Union (EU) studies. In this article, it is argued that Ukrainian resistance to the invasion must be part of an important shift in thinking about IR and the EU within holistic planetary politics. First, the terminologies and technologies of teaching IR an

Proton exchange membrane fuel cells are a promising green energy conversion technology for clean and sustainable power generation. However, effective water management remains a critical challenge. Water produced by electrochemical reactions can accumulate within porous electrodes and flow channels, leading to flooding that impedes the reverse transport of reactant gases to the reaction zone, there

This article examines the media construction of Duke Johan of Östergötland (1589–1618), a Swedish prince, through the lens of his recorded gift giving practices. It posits that gifts should be conceptualized as media, shaping the construction of Duke Johan as a ruler and virtuous prince, both in the early seventeenth century and for posterity. By analyzing the remediation of Duke Johan’s gift givi

Between 1850 and 1930, millions of Europeans emigrated to the United States, attracted by opportunities for a better life. We study the role of migrant networks in fostering emigration, using individual-level Swedish full-count census data for men and women, linked to emigration records. Our findings show that having previously migrating siblings was an important determinant of emigration, particu

We propose a single-shot Carrier-Envelope Phase measurement scheme, based on evaluating f-2f fringes by means of optical Fourier transform. The method is suitable for measuring at high-repetition rate (> 200kHz) and low pulse energy.

Acute mesenteric venous thrombosis accounts for up to 20% of all patients with acute mesenteric ischemia in high-income countries and is a very difficult disease to diagnose on clinical grounds. However, owing to the increased availability and evolution of computed tomography in high-income countries, early diagnosis prior to the development of peritonitis is often possible. First-line therapy is

Background: Recurrent coarctation of the aorta (re-CoA) is a well-known although not fully understood complication after surgical repair, typically occurring in 10%–20% of cases within months after discharge. Objectives: To (1) characterize geometry of the aortic arch and blood flow from pre-discharge magnetic resonance imaging (MRI) in neonates after CoA repair; and (2) compare these measures bet

This paper investigates online gender-based violence (OGBV) in China using the perspectives of queer feminism and cyberfeminism. As a case study, it examines the cyberviolence against the “Pink Hair Girl” on Xiaohongshu (a popular Chinese social media platform) and the subsequent resistance by women. The study focuses on the following questions: How does the symbolic use of pink hair represent que

The work studied the concept of introducing electrolyzer waste heat in between the district heating condensers to study the effects. This was done through IPSEpro where a model of a small-scale Swedish CHP-station was built. Two different cases were analyzed, where one CHP-station was analyzed as an existing (i.e., a fixed geometry) station and the other as a future potential station with external

In recent decades, changes in vegetation phenology have exhibited a tight coupling with global warming. Mountain ecosystems are particularly susceptible to climate change, with high elevations warming faster than lower areas. The inconsistent rate of temperature change across elevations may lead to synchronization of phenological patterns, reducing the differences in phenology timing between high

Background: The utilization of PD1 and CTLA4 inhibitors has revolutionized the treatment of malignant melanoma (MM). However, resistance to targeted and immune-checkpoint-based therapies still poses a significant problem. Objective: Here, we mine large-scale MM proteogenomic data to identify druggable targets and forecast treatment efficacy and resistance. Methods: Leveraging protein profiles from

This study presents a novel approach using Gaussian process model predictive control (MPC) to stabilize the output voltage of a polymer electrolyte fuel cell (PEFC) by regulating hydrogen and airflow rates. Two Gaussian process models capture PEFC dynamics, accounting for constraints like hydrogen pressure and input change rates to reduce predictive control errors. The performance of the physical

Satellite remote sensing offers global-scale soil moisture (SM) estimation to assess water and energy cycles. However, the coarse resolution of SM products from microwave remote sensing is unsuitable for fine-scale analysis. This study explored spatial downscaling methods to refine the 0.25° ESA CCI SM product to a 1-km resolution, utilizing optical and thermal remote sensing data, including the n

The widespread adoption of lithium-ion batteries (LIBs) across energy storage systems, electric vehicles, and consumer electronics is accelerating, yet the safety challenges associated with thermal runaway (TR) events remain incompletely understood. This report presents a structured review of current knowledge regarding flammable and toxic gas emissions from LIBs during TR, the consequences for fiThe widespread adoption of lithium-ion batteries (LIBs) across energy storage systems, electric vehicles, and consumer electronics is accelerating, yet the safety challenges associated with thermal runaway (TR) events remain incompletely understood.

An optimal control problem on finite-dimensional positive cones is stated. Under a critical assumption on the cone, the corresponding Bellman equation is satisfied by a linear function, which can be computed by convex optimization. A separate theorem relates the assumption on the cone to the existence of minimal elements in certain subsets of the dual cone. Three special cases are derived as examp

Cybersecurity has in recent years emerged as a paramount concern in the design and operation of industrial systems and civil infrastructures, due mainly to their susceptibility to malicious cyber attacks which take advantage of the vulnerability of communication networks and IT devices. In this paper, we investigate such an attack and counter attack scenario by considering multiagent systems, a so
