Colour vision in ants (Formicidae, Hymenoptera)

Ants are ecologically one of the most important groups of insects and exhibit impressive capabilities for visual learning and orientation. Studies on numerous ant species demonstrate that ants can learn to discriminate between different colours irrespective of light intensity and modify their behaviour accordingly. However, the findings across species are variable and inconsistent, suggesting that

The anthropocene debate and political science

Anthropocene has become an environmental buzzword. It denotes a new geological epoch that is human-dominated. As mounting scientific evidence reveals, humankind has fundamentally altered atmospheric, geological, hydrological, biospheric, and other Earth system processes to an extent that the risk of an irreversible system change emerges. Human societies must therefore change direction and navigate

Introduction : A Political Science Perspective on the Anthropocene

Over the past decades, it has become more and more obvious that ongoing globalisation processes have substantial impacts on the natural environment. Studies reveal that intensified global economic relations have caused or accelerated dramatic changes in the Earth system, defined as the sum of our planet’s interacting physical, chemical, biological and human processes (Schellnhuber et al. 2004). Cl

Molecular advances to study the function, evolution and spectral tuning of arthropod visual opsins

Visual opsins of vertebrates and invertebrates diversified independently and converged to detect ultraviolet to long wavelengths (LW) of green or red light. In both groups, colour vision largely derives from opsin number, expression patterns and changes in amino acids interacting with the chromophore. Functional insights regarding invertebrate opsin evolution have lagged behind those for vertebrat

Colour vision in stomatopod crustaceans

The stomatopod crustaceans, or mantis shrimps, are colourful marine invertebrate predators. Their unusual compound eyes have dorsal and ventral regions resembling typical crustacean apposition designs separated by a unique region called the midband that consists of from two to six parallel rows of ommatidia. In species with six-row midbands, the dorsal four rows are themselves uniquely specialized

Extremal states and coupling properties in electroelasticity

Electroelastic materials possess properties most attractive for the design of smart devices and systems such as actuators and sensors. Typical polymers show changes in shape under the action of an electric field, and vice versa, together with fast actuation times, high strain levels and low elastic moduli. This paper deals with an Ogden model inspired framework for large deformation electroelastic

The Political Impact of the Sustainable Development Goals : Transforming Governance through Global Goals?

Written by an international team of over sixty experts and drawing on over three thousand scientific studies, this is the first comprehensive global assessment of the political impact of the Sustainable Development Goals, which were launched by the United Nations in 2015. It explores in detail the political steering effects of the Sustainable Development Goals on the UN system and the policies of

Dependencies of Four Mechanisms of Secondary Ice Production on Cloud-Top Temperature in a Continental Convective Storm

Various mechanisms of secondary ice production (SIP) cause multiplication of numbers of ice particle, after the onset of primary ice. A measure of SIP is the ice enhancement ratio (“IE ratio”) defined here as the ratio between number concentrations of total ice (excluding homogeneously nucleated ice) and active ice-nucleating particles (INPs). A convective line observed on 11 May 2011 over the Sou

The performance of plasma amyloid beta measurements in identifying amyloid plaques in Alzheimer's disease : a literature review

The extracellular buildup of amyloid beta (Aβ) plaques in the brain is a hallmark of Alzheimer's disease (AD). Detection of Aβ pathology is essential for AD diagnosis and for identifying and recruiting research participants for clinical trials evaluating disease-modifying therapies. Currently, AD diagnoses are usually made by clinical assessments, although detection of AD pathology with positron e

Cholesterol metabolism in breast cancer: Prognostic factors and optimizing treatment

AbstractBreast cancer (BC) is the most common cancer among women in Sweden and worldwide. Adjuvant endocrine therapies are effective, yet 20-30% patients experience disease relapse. Altered cholesterol metabolism is an emerging hallmark of breast cancer proliferation and endocrine therapy resistance. Studies have shown that the use of cholesterol-lowering medications (statins) reduces the risk of

Site-dependent nuclear dynamics in core-excited butadiene

Symmetry breaking and competition between electronic decay and nuclear dynamics are major factors determining whether the memory of the initial core-hole localisation in a molecule is retained long enough to affect fragmentation. We investigate the fate of core holes localised at different sites in the free 1,3 trans butadiene molecule by using synchrotron radiation to selectively excite core

Skogen är bäst på bild

Skogen är bäst på bild is an electroacoustic text-sound-composition work; it could also be considered a radiophonic work. This was the first work of text-sound composition I ever made, repurposing that more abstract genre here as a direct tool for finding memory and identity in the city. Although Stockholm’s history of text-ljud-komposition (text-sound-composition) is something I have engaged with

Under stjärnvalvets drömmar

Under stjärnvalvets drömmar is a 19-minute, MIDI-driven composition for the Skandia theater organ, a 1926 Wurlitzer Unit Orchestra instrument that was refurbished and given a new home in the Reaktorhallen (The Reactor Hall, or “R1”) over the entire year of 2021. R1 is a huge, cavernous former nuclear reactor hall, several stories underground, hewn out of solid rock. The work is a collection of con

Ghost Installation: Kafferepet

Ghost Installation Kafferepet is one of several "Ghost Installation" compositions in the project. Using small, consumer grade speakers and looping sound collage files, these sound installation compositions are placed in multichannel arrays into the sites they address.Ghost Installation: Kafferepet was installed outside the former site of the Kafferepet konditori (traditional Swedish coffee house),

Ghost Installation: Cyklopen

I was asked to make this installation on the occasion of Cyklopen’s 5th anniversary celebration in their new building. Cyklopen is an “anarchist cultural house” in the Högdalen neighborhood, a suburb in the south of Stockholm. There was to be a great deal of loud music, crowds, presentations and general festivities, so I decided to make an oasis in the library, where some artworks were hanging. Lo

Ghost Installation: Sparvkvarteren

Ghost Installation: Sparvkvarteren was part of the same evening that Deuterium: Virkesvägen was composed for. It was made with a single, combined recording of sparrows from Solna, Tensta and Hammarby, two clips of synthesizer material, and two recordings of the construction machinery closing in on Virkesvägen 3, recorded the same week we made our event in the Coyote Collective’s exhibition, Pionee

Ghost Installation: Rönnells

In January of 2022, I made an installation event at Rönnells. I set larger speakers up on the balcony, and played three of the large-scale multi-channel compositions from this project– Skogen är bäst på bild, Vädersolsmodernitet and Vart ska dom ta vägen nu?–at a very much lowered volume. I made them hoping they could function both as concert pieces and as installations. The event at Rönnels prove

Virvelns trädgård

The garden at the Moderna Museet is a garden for a future – even a post-future! – which had already passed into history when I arrived in 2011. I spent much of that summer contemplating this paradox through the lens of the presence and resonating echoes of Frukost i den Gröna and Paradiset. Even more, the colorful story of the Bucky Dome which had been erected in the garden illuminated the recentl
