Aims. Dust plays a crucial role in the evolution of protoplanetary disks. We study the dynamics and growth of initially submicron dust particles in self-gravitating young protoplanetary disks with various strengths of turbulent viscosity. We aim to understand the physical conditions that determine the formation and spatial distribution of pebbles when both disk self-gravity and turbulent viscosity
Calcareous nannofossils evolved in the global ocean from the Carnian (early Late Triassic) and have contributed to the accumulation of biogenic calcium carbonate in marine sediments since then. Bio-diversification and bio-productivity became more significant in the Rhaetian (Late Triassic), representing an important period to understand the dynamics of calcareous nannofossil evolution. The calcare
As a fuel for power generation, high-pressure hydrogen gas is widely used for transportation, and its efficient storage promotes the development of fuel cell vehicles (FCVs). However, as the filling process takes such a short time, the maximum temperature in the storage tank usually undergoes a rapid increase, which has become a thorny problem and poses great technical challenges to the steady ope
One year into Russia’s full-scale invasion of Ukraine, the West is in need for a diversified strategy when discussing the conflict with its partners. Due to historical experiences, non-European and non-Western countries look at the Russian aggression differently. Supporting Ukraine thus means learning how communicate the consequences of the ongoing invasion in a language that would take into accou
Consider discrete-time linear distributed averaging dynamics, whereby a finite number of agents in a network start with uncorrelated and unbiased noisy measurements of a common state of the world modeled as a scalar parameter, and iteratively update their estimates following a non-Bayesian learning rule. Specifically, let every agent update her estimate to a convex combination of her own current e
We propose a competition-based approach to resilient distributed optimization with quadratic costs in Networked Control Systems (e.g., wireless sensor network, power grid, robotic team) where a fraction of agents may misbehave (through, e.g., hacking or power outage). Departing from classical filtering strategies proposed in literature, and inspired by a game-theoretic interpretation of consensus,
A critical aspect in strategic modeling of transportation systems is user heterogeneity. In many real-world scenarios, e.g., when tolls are charged and drivers have different trade-offs between time and money, or when they get informed about current congestion by different routing apps, modeling users as rational decision makers with homogeneous utility functions becomes too restrictive. While glo
It is well established that women's sexual and reproductive health (SRHR) is negatively affected by war. While global health research often emphasises infrastructure and systematic factors as key impediments to women's SRHR in war and postwar contexts, reports from different armed conflicts indicate that women's reproduction may be controlled both by state and other armed actors, limiting women's
Ekonomiskt bistånd är det svenska välfärdssystemets yttersta skyddsnät. Biståndet syftar till att ge tillfälligt ekonomiskt stöd till dem som inte har några andra sätt att försörja sig, eller när inkomster eller socialförsäkringsförmåner inte räcker. Ekonomiskt bistånd regleras av SoL, en målrationell ramlag som redogör för vad biståndet ämnar åstadkomma snarare än att detaljstyra handläggningen oSocial assistance is the last safety net of the Swedish welfare system. It is designed to aid those individuals whom cannot support themselves through funds or income, including any form of social security. The Social Services Act, the law that regulates social assistance, is a framework law which focuses on the outcome of the assistance rather than the basis of eligibility assessment. At the same
BackgroundDespite the fact that eldercare services are organizationally part of social work in Sweden, the social work practice is disappearing and older people are expected to take the responsibility for their own well-being. In this context, they have to create their own sense of meaningfulness in their everyday life, despite being subject to social care services.Methods As part of a research prBackgroundDespite the fact that eldercare services are organizationally part of social work in Sweden, the social work practice is disappearing and older people are expected to take the responsibility for their own well-being.

This article describes the collaborative creation of the curriculum for a new eLearning programme on daylighting design of buildings targeting both traditional and lifelong learners. The programme consists of an online platform integrated with a summer school for practical applications. The curriculum was developed through several workshops with professionals, representatives of national bodies on
