Chemical signaling is ubiquitous and employs a variety of receptor types to detect the cacophony of molecules relevant for each living organism. Insects, our most diverse taxon, have evolved unique olfactory receptors with as little as 10% sequence identity between receptor types. We have identified a promiscuous volatile, 2-methyltetrahydro-3-furanone (coffee furanone), that elicits chemosensory
#104_loga, a nonlinear scale of time, for tpt, tbn. “loga, a nonlinear scale of time” refers to the illusion of nonlinear time perception. This idea suggests that our estimation of time intervals whether on a small (milliseconds) or large (decades) scale should be logarithmic, giving us a subjective experience very different from clock or calendar. Of course, our perception of time is influenced b
The development of materials that are non-magnetic in the bulk but exhibit two-dimensional (2D) magnetism at the surface is at the core of spintronics applications. Here, we present the valence-fluctuating material EuIr2Si2, where in contrast to its non-magnetic bulk, the Si-terminated surface reveals controllable 2D ferromagnetism. Close to the surface the Eu ions prefer a magnetic divalent confi
Thirteen years of measurements of ultrafine (3-10 nm diameter) aerosols are presented from a remote high elevation (3210 m a.s.l.) site in Colorado, Storm Peak Laboratory. Previous work has shown that frequent new particle formation (NPF) occurs regularly at the site (52% of days). This long-term climatology of ultrafine aerosols clearly shows a seasonal dependence on new particle formation at Sto
The traditional opinion that increased intraocular pressure is the cause of glaucoma is controversial, probably mainly because of the fact that firm evidence for the value of pressure reduction is largely lacking. The present article reviews results from short term studies of visual fields before and after pressure reduction. It also reviews published and unpublished preliminary results from studi
Background. Epidemiological studies indicate that physical activity reduces the risk of cancer. Physical inactivity or sedentary behavior, has recently been suggested as a risk factor independent of physical activity level. Breast and endometrial cancer incidence have both been associated with physical activity, and endometrial cancer incidence with physical inactivity/sedentary behavior. The purp
In temperate systems, phytoplankton spring blooms deplete inorganic nutrients and are major sources of organic matter for the microbial loop. In response to phytoplankton exudates and environmental factors, heterotrophic microbial communities are highly dynamic and change their abundance and composition both on spatial and temporal scales. Yet, most of our understanding about these processes comes
Aim: To increase understanding of the consequences of growing up with substance-abusing parents, including how this can influence the experience of becoming a parent. Methods: In-depth interviews were conducted with 19 parents who had participated in an Infant and Toddler Psychiatry Unit intervention programme and who had experienced substance-abusing parents in their family of origin. Directed qu
Background: Stored potato (Solanum tuberosum L.) tubers are sensitive to wet conditions that can cause rotting in long-term storage. To study the effect of water on the tuber surface during storage, microarray analysis, RNA-Seq profiling, qRT-PCR and phytohormone measurements were performed to study gene expression and hormone content in wet tubers incubated at two temperatures: 4 °C and 15 °C. Th
The world has witnessed a rapidly aging China and as a result of the social changes, numerous elderly people are living alone in rural and urban areas. No matter how they have been termed, the reality about the contemporary Chinese elders is that their needs for care is unlikely to be met. Previous researches pursing the theme of modernization in the contemporary Chinese society have argued that a
In this thesis, a house price evolution equation of Denmark's municipalities is proposed and solved using both an iterative optimization algorithm, and a closed form solution using Vector Autoregression. The quality of the solutions is investigated, analyzed and compared. Focus is put on the accuracy of the generated price predictions and to what degree the model parameters follow expected fea
This thesis is based on the research that I conducted in a co-working space called The Ground, located in Slussen, Malmö, Sweden. The aim of the research is to investigate how The Ground (and other co-working spaces, as well) can become more pro-active in facilitating collaborations, especially inside its own community. The Ground is a small host organization itself. Parallel to its future growth,
Background In recent years, supply chains have faced major disruptions, including the Covid-19 pandemic, the Suez Canal blockage, and the Russia-Ukraine war, highlighting their vulnerability. As supply chains have become more global and interconnected, the complexity of supply chain networks has increased, leading to them being more exposed to risks. This has resulted in disruptions becoming more
To mitigate greenhouse gas emissions resulting from the combustion of fossil fuels in conventional transportation—including vehicles, ships, and aircraft—a wide range of alternative energy sources have been explored, such as liquefied natural gas (LNG), methanol, liquefied petroleum gas (LPG), biomass, solar energy, hydrogen, fuel cells, and batteries. Among these, battery electric propulsion syst
