Wildfires pose a significant risk to human livelihoods and are a substantial health hazard due to emissions of toxic smoke. Previous studies have shown that climate change, increasing atmospheric CO2, and human demographic dynamics can lead to substantially altered wildfire risk in the future, with fire activity increasing in some regions and decreasing in others. The present study re-examines the

A new simplifed formula is derived for the absorption cross section of small dielectric ellipsoidal particles embedded in lossy media. The new expression leads directly to a closed form solution for the optimal conjugate match with respect to the surrounding medium, i.e. the optimal permittivity of the ellipsoidal particle that maximizes the absorption at any given frequency. This defnes the optim

Background: Choroid plexus (CP) supports the entry of monocyte-derived macrophages (MDMs) to the central nervous system in animal models of traumatic brain injury, spinal cord injury, and Alzheimer's disease. Whether the CP is involved in the recruitment of MDMs to the injured brain after ischemic stroke is unknown. Methods: Adult male C57BL/6 mice were subjected to focal cortical ischemia by perm

We will in this paper present methods and algorithms for estimating two-view geometry based on an orthographic camera model. We use a previously neglected nonlinear criterion on rigidity to estimate the calibrated essential matrix. We give efficient algorithms for estimating it minimally (using only three point correspondences), in a least squares sense (using four or more point correspondences),

While the concepts of planning and scheduling seem to be adequately discussed in the project management literature, relatively few examples of factors specifically affecting the performance of planning and scheduling are to be found. The study reported in this paper investigated a set of factors identified as enablers and barriers to successful project planning and scheduling of construction proje

The literature during 2000–2016 about drying of biofuels from the forest has been reviewed. Biofuels constitute a low-cost energy resource that is likely to continue to increase and the dryers for such products should be simple, robust, and easy to operate. In 1970s and 1980s, rotary dryers and flash dryers were the most common types, and in 1990s, superheated steam (SHS) dryers became common. Mai

When survivors from the Ravensbrück concentration camp arrived in Sweden in spring 1945, some of the objects they brought with them from the camp were collected and preserved. These are modest in appearance, but were – as oral testimonies show – invaluable in camp. The concentration camp context of obliteration stretches the limits of interpretation of material culture to its extreme. In this arti

Pervasiveness and complexity of modern software are challenging engineers to design applications able to guarantee the desired quality of service despite unpredictable runtime variations in their execution environment. A variety of techniques have been proposed in the last year for the design of self-adaptive applications; however, most of them is tailored to specific applications or can provide l

It is well established that high ambient heat could cause congenital abnormalities resulting in miscarriage or stillbirth among certain species of mammals. However, this has not been systematically studied in real field settings among humans, despite the potential value of such knowledge for estimating the impact of global warming on the human species. This study sought to test the hypothesis that

The fracture behaviour of ferritic and ferritic martensitic steels in ductile to brittle transition (DBT) region has been extensively studied in recent years and a probabilistic approach of master curve method is generally used to describe the fracture toughness of BCC steels in DBT region as a function of temperature. The assessment of cleavage failure probability however is still untouched in th

We have studied how energy efficiency is discussed by professionals during renovation of multifamily dwellings, in order to capture how barriers in relation to energy measures are appearing, disappearing and transformed during the process. We did participatory observations of renovation meetings, conducted interviews with the involved professionals and studied-related documents. Our intentions hav

This manuscript describes harmonic generation in semiconductor superlattices, starting from a nonequilibrium Green's functions input to relaxation rate-type analytical approximations for the Boltzmann equation in which imperfections in the structure lead to asymmetric current flow and scattering processes under forward and reverse bias. The resulting current-voltage curves and the predicted conseq

The future of solid-state lighting can be potentially driven by applications of InGaN/GaN core-shell nanowires. These heterostructures provide the possibility for fine-tuning of functional properties by controlling a strain state between mismatched layers. We present a nondestructive study of a single 400 nm-thick InGaN/GaN core-shell nanowire using two-dimensional (2D) X-ray Bragg ptychography (X

Summary: Brain Computer interfaces (BCIs) are stable inside the brain over long periods of time and that have minimal effects on the physiological conditions of the neural tissue. This chapter reviews the state-of-the-art of neural interfaces and the concepts behind recent research and development of biocompatible BCIs. It focuses on various tissue responses in the brain to an implanted foreign bo
