We propose a traffic model based on microscopic stochastic dynamics. We built a Markov chain equipped with an Arrhenius interaction law. The resulting stochastic process is comprised of both spin-flip and spin-exchange dynamics which models vehicles exiting, entering and interacting in a two-dimensional lattice environment corresponding to a multi-lane highway. The process is further equipped with

Proton radioactivity was discovered exactly 50 years ago. First, this nuclear decay mode sets the limit of existence on the nuclear landscape on the neutron-deficient side. Second, it comprises fundamental aspects of both quantum tunnelling as well as the coupling of (quasi)bound quantum states with the continuum in mesoscopic systems such as the atomic nucleus. Theoretical approaches can start ei

Titanium-aluminium nitride (Ti1-xAlxN) coatings are used to achieve high oxidation and wear resilience in coated metal cutting tools. For the highest performance, the coatings' composition and microstructure are carefully controlled. However, it is difficult to obtain knowledge how these factors affect of the oxidation processes at the microstructural level because studies are most commonly perfor

Here, it is shown that when two optical frequency combs with identical mode spacing but different offset frequencies copropagate through a nonlinear optical fiber, four-wave mixing between them generates new modes. Although the spacings between the new modes depend on the difference of the offset frequencies, they appear irregular because of the large number of possible four-wave-mixing processes.

One of the prototype compounds for metal-metal multiple bonding, the Re2Cl82- ion, has been studied theoretically using multiconfigurational quantum chemical methods. The molecular structure of the ground state has been determined. It is shown that the effective bond order of the Re-Re bond is close to three, due to the weakness of, in particular, the bond. The electronic spectrum has been calcula

The importance of proper mutational analysis of BRCA1/2 in individuals at risk for hereditary breast and ovarian cancer syndrome is widely accepted. Standard genetic screening includes targeted analysis of recurrent, population-specific mutations. The purpose of the study was to establish the frequency of germline BRCA1/2 mutations in a group of 134 unrelated patients with primary ovarian cancer.

Neutron deficient nuclei with mass numbers A approximate to 90 and 40 less than or equal to Z less than or equal to 44 have been studied making use of the Osiris and Nordball spectrometers. The high spin states of these nuclei and their electromagnetic decay properties are compared to shell model calculations based on the core Sr-88 and using different parametrizations of the residual interaction.

Background Exclusive breastfeeding is essential for infant health, yet its practice varies across generations and cultures. Although the health benefits of breastfeeding have been well known for decades, the utilization of infant formula feeding worldwide and in Oman, in particular, continues to rise, most likely as a result of a lack of social support and the time limit faced by working mothers.

Background: Alloreactive memory T cells are a major obstacle to transplantation acceptance due to their capacity for accelerated rejection. Methods: C57BL/6 mice that had rejected BALB/c skin grafts 4 weeks earlier were used as recipients. The recipient mice were treated with anti-CD154/LFA-1 with or without anti-CD70 during the primary skin transplantation and anti-CD154/LFA-1 or not during the s

30 september 2025 15:15 till 16:00 | Seminarium The Department of Chemistry welcomes you an open lecture. At the KILU-seminars preeminent scientists present their work in a chemistry wide setting. The seminar series provides an opportunity to learn about exciting current research. In addition, it is an opportunity to meet, exchange ideas and discuss science with colleagues from all around KILU and

Using the Burt-Foreman envelope function theory and an eight-band k.p model, we have extended our previous work [Semenikhin et al. Phys. Rev. B 76, 035335 (2007)] on optical transitions in InAs/GaSb quantum wells grown along the [001] direction by completing the interface Hamiltonian with the inclusion of its nonrelativistic part. We found a substantial contribution of the nonrelativistic term to

BackgroundPerfusion MRI typically refers to MRI-based measurements of microcirculatory parameters such as blood flow, blood volume and blood mean transit time. Imaging of perfusion-related parameters is of relevance in, for example, studies of dementia and trauma, assessment of the ischemic penumbra in acute ischemic stroke (in combination with diffusion MRI) to facilitate treatment decisions, inv
