This paper tests the “Square Root Rule” (the SRR), a Basel sanctioned method of scaling 1-day Value At risk to higher time horizons. The SRR has come under serious assault from leading researchers focusing on its week theoretical basis: assuming i.i.d. asset returns. I performed an empirical test of the SRR on the 10-day horizon, the maximum horizon allowed by Basel, comparing SRR performance to d
Climate change and disasters pose a serious risk to sustainable development. In the South local coping strategies are an important element of adaptation to climate and disaster risk. Such strategies have arisen because of the limited assistance provided by urban actors and associated social security and governance systems. In contrast, in the North local coping strategies are comparatively poorly
The development of integrated pest management is hampered by lack of information on how insect pest abundances relate to yield losses, and how pests are affected by control measures. In this study, we develop integrated pest management tactics for Apion spp. weevils (Coleoptera: Brentidae) in seed production of red clover, Trifolium pratense L. We tested a method to forecast pest damage, quantifie
The world supply and turnover of copper was modelled using simple empirical estimates and a COPPER systems dynamics model developed for this study. The model combines mining, trade markets, price mechanisms, population dynamics, use in society and waste as well as recycling, into a whole world system. The degree of sustainability and resource time horizon was estimated using four different methods
A kinetic model of the fermentative production of lactic acid from glucose by Lactococcus lactis ssp. lactis ATCC 19435 in whole-wheat flour has been developed. The model consists of terms for substrate and product inhibition as well as for the influence of pH and temperature. Experimental data from fermentation experiments under different physical conditions were used to fit and verify the model.
The emergence of markets for online physician consultations -- direct-to-consumers telemedicine (DCT) -- is transforming healthcare services in many nations. The convenience of DCT lowers the cost of seeking care, thus potentially increasing demand. Yet, it is not known whether patients consuming online care turn to traditional providers as well. This is one of the first studies to causally assess
Computer simulation can provide valuable insight into the forces driving biomolecular liquid-liquid phase separation. However, the simulated systems have a limited size, which makes it important to minimize and control finite-size effects. Here, using a phenomenological free-energy ansatz, we investigate how the single-phase densities observed in a canonical system under coexistence conditions dep
The formation of biomolecular condensates inside cells often involve intrinsically disordered proteins (IDPs), and several of these IDPs are also capable of forming dropletlike dense assemblies on their own, through liquid-liquid phase separation. When modeling thermodynamic phase changes, it is well known that finite-size scaling analysis can be a valuable tool. However, to our knowledge, this ap
Henzinger et al. posed the so-called Online Boolean Matrix-vector Multiplication (OMv) conjecture and showed that it implies tight hardness results for several basic dynamic or partially dynamic problems [STOC'15]. We first show that the OMv conjecture is implied by a simple off-line conjecture that we call the MvP conjecture. We then show that if the definition of the OMv conjecture is generalize
Decreasing floral resources as a result of habitat loss is one of the key factors in the decline of pollinating insects worldwide. Understanding which plants pollinators use is vital to inform the provision of appropriate floral resources to help prevent pollinator loss. Using a globally important pollinator, the honeybee, we show how changes in agricultural intensification, crop use and the sprea
Grass (Poaceae) pollen is the most important outdoor aeroallergen,1 exacerbating a range of respiratory conditions, including allergic asthma and rhinitis ("hay fever").2-5 Understanding the relationships between respiratory diseases and airborne grass pollen with a view to improving forecasting has broad public health and socioeconomic relevance. It is estimated that there are over 400 million pe
Allergic rhinitis is an inflammation in the nose caused by overreaction of the immune system to allergens in the air. Managing allergic rhinitis symptoms is challenging and requires timely intervention. The following are major questions often posed by those with allergic rhinitis: How should I prepare for the forthcoming season? How will the season's severity develop over the years? No country yet
This page provides information about the University's work with gender equality and equal opportunities. The annual National Conference for Equal opportunities in Lund, 17–18 November In 2026, the conference will be organised by Lund University on 17–18 November. The theme is One college, one university for everyone. The conference is aimed at everyone working in the higher education sector, as we
Education for sustainability (EfS) has been regarded a promising approach for solving sustainability challenges. Results have been unsatisfying due to a knowledge-dissemination focus in the formal sector. Reasons are economic and political interests shaping formal education. Therefore, hopes are placed in the non-formal sector to close this knowledge-to-action gap. In this case study, I aim to und
Background: Randomised clinical trials with a factorial design may assess the effects of multiple interventions in the same population. Factorial trials are carried out under the assumption that the trial interventions have no interactions on outcomes. Here, we present a protocol for a simulation study investigating the consequences of different levels of interactions between the trial interventio
Quantum annealing is a promising approach for obtaining good approximate solutions to difficult optimization problems. Folding a protein sequence into its minimum-energy structure represents such a problem. For testing new algorithms and technologies for this task, the minimal lattice-based [hydrophobic (H) or polar (P) beads] HP model is well suited, as it represents a considerable challenge desp
