The relations between the Schrödinger and wave evolutions are investigated. A generalization of the Lax-Phillips scattering theory for the case of the Schrödinger equation is constructed. An analog of the wave decay operator is obtained. The general ideas are illustrated by an explicitly solvable model of multichannel scattering on the halfaxis. A Lax-Phillips scattering theory is developed for th

A methodology for safety verification using barrier certificates has been proposed recently, Conditions that must be satisfied by a barrier certificate can be formulated as a convex program, and the feasibility of the program implies system safety, in the sense that there is no trajectory starting from a given set of initial states that reaches a given unsafe region. The dual of this problem, i.e.

Miniaturization to the micrometer and nanometer scale opens up the possibility to probe biology on a length scale where fundamental biological processes take place, such as the epigenetic and genetic control of single cells. To study single cells the necessary devices need to be integrated on a single chip; and, to access the relevant length scales, the devices need to be designed with feature siz

The interdisciplinary symposium ”Microstructures of Learning: Novel methods and approaches for assessing structural and functional changes underlying knowledge acquisition in the brain” took place on May 23, 2014 in Lund, Sweden. The cross-disciplinary meeting brought together researchers from linguistics, psychology, physics, chemistry, and neuroscience in order to discuss how knowledge, in part

Popular Abstract in Swedish Ett system där flera personer och maskiner kan kommunicera samtidigt över ett gemensam medium kallas ett fleranvändarsystem. Den här avhandlingen presenterar och analyserar olika fleranvändarsystem där mediet består av en radiokanal med hög bandbredd. Analyser av hur många användare som kan kommunicera samtidigt och olika sätt för att öka denna kapacitet är presenterad.Wideband CDMA (Code Division Multiple Access) is one of the key technologies for future mobile communication systems. This thesis studies various coding and transmission methods for wideband CDMA communications. In a cellular environment, the system performance depends on the interference from other cells. An analysis of the other-cell interference in the forward link, from the base station to the

This talk describes the work done in calculating leading logarithms in massive effective field theories. We discuss shortly leading logarithms in renormalizable theories and how they can be calculated using only one-loop calculations in effective field theories. The remainder of the talk discusses masses, decay constants, condensates and anomalous processes in mesonic effective field theories like

This study investigates the effects of Age of Onset of Acquisition (AOA) and the quality and quantity of input on the longitudinal development of gender in the acquisition of French by simultaneous (2L1) and successive bilingual children (cL2). There's an on-going debate regarding the main factors underlying linguistic development in bilingual children. Two independent variables, AOA and input, ha

The Gaia space observatory has produced astrometric measurements of extraordinary precision, enabling detection of exoplanets through the reflex motion of their host stars. With Gaia Data Release 4 (DR4) scheduled for December 2026, which will include full epoch astrometry, methods for orbital parameter recovery are needed. This work presents a Bayesian Markov Chain Monte Carlo (MCMC) framework fo

How does violent conflict affect the spread of Covid-19? In this paper we analyze how violent conflict influences the adoption of preventative measures and infection rate in a very poor, conflict-affected country, Burkina Faso. We use a unique panel of 1,919 households surveyed during the first six months of the Covid-19 pandemic in 2020 and merge these data with indicators of violence at the muni

Adaptive plasticity processes are required involving neurons as well as non-neuronal cells to recover lost brain functions after an ischemic stroke. Recent studies show that gamma-Aminobutyric acid (GABA) has profound effects on glial and immune cell functions in addition to its inhibitory actions on neuronal circuits in the post-ischemic brain. Here, we provide an overview of how GABAergic neurot

The objective of the paper is to explore whether particular problematisations of cars and car use lead to sets of solutions that may not deal with all problems associated with car use, and whether this leads to any internal conflicts within the chosen policies. The paper is based on a review of local transport policy documents from 13 cities in four countries using the lens of policy problematisat

AIMS: Patients with femoral neck fractures (FNFs) treated with total hip arthroplasty (THA) have an almost ten-fold increased risk of dislocation compared to patients undergoing elective THA. The surgical approach influences the risk of dislocation. To date, the influence of differing head sizes and dual-mobility components (DMCs) on the risk of dislocation has not been well studied. METHODS: In a
