In this work, we propose a novel method for interpolation and extrapolation of Toeplitz structured covariance matrices. By considering a spectral representation of Toeplitz matrices, we use an optimal mass transport problem in the spectral domain in order to define a notion of distance between such matrices. The obtained optimal transport plan naturally induces a way of interpolating, as well as e

We propose a formulation of the Network Design Problem (NDP) to support transport planners in dealing with multimodal networks in contexts characterised by different (and sometimes conflicting) interests and limited resources in a transparent way. We expect that the implementation of the method can increase the acceptability of transport schemes. The proposed formulation expands the scope of tradi

Objectives: To analyse and present regression models that can describe the long-term change in cognitive function (MMSE and ADAS-cog) of patients treated with donepezil for three years (n=435). Methods: The Swedish Alzheimer Treatment Study (SATS) is an open, 3-year, multicentre study in a routine clinical setting. Patients with the diagnosis of Alzheimer’s Diseases received the cholinesterase inh

The diagnosis of Alzheimer's disease can be improved by the use of biological measures. Biomarkers of functional impairment, neuronal loss, and protein deposition that can be assessed by neuroimaging (ie, MRI and PET) or CSF analysis are increasingly being used to diagnose Alzheimer's disease in research studies and specialist clinical settings. However, the validation of the clinical usefulness o

The devices that constitute the Internet of Things are evolving to include more than just enabling sensing and actuation over a wireless interface. In a contemporary scenario, these devices perform tasks and contribute to an aggregate information flow, in a distributed manner. In the wake of this evolution, new distributed Internet of Things frameworks have emerged. These frameworks maintain a dis

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

This study presents a 2-yr follow-up of 281 patients, aged 15-34 yr, diagnosed with diabetes between 1992 and 1993. At diagnosis, 224 (80%) patients were positive for at least one of the following autoantibodies: islet cell antibodies (ICAs), glutamic acid decarboxylase antibodies (GADAs), or tyrosine phosphatase antibodies (IA-2As); the remaining 57 (20%) patients were negative for all three auto

BACKGROUND: A department of forensic medicine (DFM) can be a valuable source for tissue donation, but logistics can prove difficult to overcome as it pertains to obtaining tissues for donation. This article describes the potential of tissues that can be procured for transplantation.MATERIALS AND METHODS: Sweden has 9.7 million inhabitants, with an annual mortality rate of 90 000 and 5500 medicoleg

This article argues that the Roman poet Ovid in his Metamorphoses invented the apotheosis of Hersilia into the goddess Hora as a way to flatter the empress Livia. There are compelling parallels between the words used to describe Hersilia and Livia in Ovid’s poetry. Furthermore, Hersilia was, according to the legend, a Sabine woman who married Romulus, the founder of Rome. Livia was born into the

I Lunds universitets strategiska plan för 2012-2016 framhålls att man vill ”vidareutveckla det akademiska lärarskapet”. All utbildning vid lärosätet ska hålla högsta kvalitet och man ska erbjuda attraktiva och akademiskt framstående lärandemiljöer. Detta åstadkoms bland annat genom att universitetets lärare kan ”arbeta med ett forskande förhållningssätt, både i förhållande till studenternas lärand

Foreign direct investment (FDI) has been important in the growth and global integration of developing economies. Both Northeast and Southeast Asia, especially the latter, have been part of this development, with increasing inflows of FDI and greater foreign participation in local economies. However, Indonesia has been an outlier within the region. Inflows of FDI have been lower to Indonesia than t

The production of chips is an inevitable part of any machining operation. Today, brass chips are commonly recycled through re-melting by the material supplier implying a “loop” where material is sent back and forth between the material supplier and the manufacturing company. The research presented in this paper evaluates a method for compaction and hot forging of brass chips into blanks for subseq

Hailed by economists as an idea whose time has come, the `new economic geography' has not been quite as favourably received by geographers. Frequently seen as a prime case of academic imperialism, few appear willing to concede that economists may have something to contribute to economic geography. Conversely, beyond the token reference to vintage publications, economistsoften dismiss geographers'
