While traditional forms of urban planning are oriented towards the future, the recent turn towards experimental and challenge-led urban developments is characterized by an overarching presentism. We explore in this article how an experimental approach to urban planning can consider the long-term through setting-up ‘conversations with a future situation.’ In doing so, we draw on a unique experiment

Formal modes of political incorporation in South Korea rest on a foundation of limited pluralism. The notion that the state should impose rigid boundaries on political representation pervades the country’s democracy. This notion is enshrined in law–in particular in the constitution’s Article 8 and in the Political Parties Act–and is upheld and perpetuated by the judiciary, the election commission,

A public struggle in South Korea around prosecution reform brings into focus a deeper battle between forces seeking to make the state more responsive to ordinary people and those aiming to preserve the status quo. Opponents of prosecution reform turned to a mode of politics that appropriated the styles and symbols of democracy to justify the obstruction of reforms that would break down a key autho

Användning av ytförstärkning har undersökts som ett led i att förbättra murade ytterväggars energiprestanda. De experimentella undersökningarna genomförda vid Lunds tekniska högskola visar att genom användning av ytförstärkning kan tjockleken på den bärande delen i en yttervägg minskas med mellan 30 - 50 procent jämfört med dagens väggtyper. Väggarnas bärförmågan kan samtidigt bibehållas eller ren

Evaluations about what is good (period) and what is good for someone shape much of ethics. The two value notions ‘good’ and ‘good for’ mark the deep-rooted divide between the impersonally and personally valuable—the value divide on which The Value Gap centres. Past and contemporary philosophers have argued it is a mistake to believe that these two value notions give rise to unresolvable value confIn The Value Gap, Toni Rønnow-Rasmussen addresses the distinction between what is finally good and what is finally good-for, two value notions that are central to ethics and practical deliberation. The first part of the book argues against views that claim that one of these notions is either faulty, or at best conceptually dependent on the other notion. Whereas these two views disagree on whether

Two symmetrically coupled populations of N oscillators with inertia m display chaotic solutions with broken symmetry similar to experimental observations with mechanical pendulums. In particular, we report evidence of intermittent chaotic chimeras, where one population is synchronized and the other jumps erratically between laminar and turbulent phases. These states have finite lifetimes diverging

Survival in aquatic environments requires organisms to have effective means of collecting information from their surroundings through various sensing strategies. In this study, we explore how sensing mode and range depend on body size. We find a hierarchy of sensing modes determined by body size. With increasing body size, a larger battery of modes becomes available (chemosensing, mechanosensing,

A large variety of complex systems in ecology, climate science, biomedicine and engineering have been observed to exhibit tipping points, where the dynamical state of the system abruptly changes. For example, such critical transitions may result in the sudden change of ecological environments and climate conditions. Data and models suggest that detectable warning signs may precede some of these dr

The synchronization of coupled oscillators is a fascinating manifestation of self-organization that nature uses to orchestrate essential processes of life, such as the beating of the heart. Although it was long thought that synchrony and disorder were mutually exclusive steady states for a network of identical oscillators, numerous theoretical studies in recent years have revealed the intriguing p

We propose a phenomenological model for the polygonal hydraulic jumps discovered by Ellegaard and co-workers, based on the known flow structure for the type-II hydraulic jumps with a "roller" (separation eddy) near the free surface in the jump region. The model consists of mass conservation and radial force balance between hydrostatic pressure and viscous stresses on the roller surface. In additio

Cancer results from a sequence of genetic and epigenetic changes that lead to a variety of abnormal phenotypes including increased proliferation and survival of somatic cells and thus to a selective advantage of precancerous cells. The notion of cancer progression as an evolutionary process has been attracting increasing interest in recent years. A great deal of effort has been made to better unde

A fundamental problem of asexual adaptation is that beneficial substitutions are not efficiently accumulated in large populations: Beneficial mutations often go extinct because they compete with one another in going to fixation. It has been argued that such clonal interference may have led to the evolution of sex and recombination in well-mixed populations. Here, we study clonal interference, and

We study a network of three populations of coupled phase oscillators with identical frequencies. The populations interact nonlocally, in the sense that all oscillators are coupled to one another, but more weakly to those in neighboring populations than to those in their own population. Using this system as a model system, we discuss for the first time the influence of network topology on the exist

We study a triangular network of three populations of coupled phase oscillators with identical frequencies. The populations interact nonlocally, in the sense that all oscillators are coupled to one another, but more weakly to those in neighboring populations than to those in their own population. This triangular network is the simplest discretization of a continuous ring of oscillators. Yet it dis

Spiral waves are ubiquitous in two-dimensional systems of chemical or biological oscillators coupled locally by diffusion. At the center of such spirals is a phase singularity, a topological defect where the oscillator amplitude drops to zero. But if the coupling is nonlocal, a new kind of spiral can occur, with a circular core consisting of desynchronized oscillators running at full amplitude. He

We analyze a large system of globally coupled phase oscillators whose natural frequencies are bimodally distributed. The dynamics of this system has been the subject of long-standing interest. In 1984 Kuramoto proposed several conjectures about its behavior; ten years later, Crawford obtained the first analytical results by means of a local center manifold calculation. Nevertheless, many questions

As the number of rapes is increasing in Sweden, and the number of individuals convicted of these crimes is decreasing, it is of importance to study offender characteristics of those committing these crimes and the circumstances in which these crimes are conducted, such as indoors or outdoors. Data from Swedish population-based registers were used to identify individuals suspected of rape, aggravat
