Structural analysis and the process of economic development : essays in memory of Lennart Schön

Economic development is full of discontinuities. Mainstream economists perceive these as external disturbances to a natural state of equilibrium, but this book argues that much of the discontinuities are part of economic development, suggesting that patterns can be understood with structural analysis.Structural Analysis and the Process of Economic Development presents a detailed analysis of the tr

A rapid method for selecting suitable animal species for studying pathogen interactions with plasma protein ligands in vivo

Species tropism constitutes a serious problem for developing relevant animal models of infection. Human pathogens can express virulence factors that show specific selectivity to human proteins, while their affinity for orthologs from other species can vary significantly. Suitable animal species must be used to analyse whether virulence factors are potential targets for drug development. We develop

Short-term ammonium supply induces cellular defence to prevent oxidative stress in Arabidopsis leaves

Plants can assimilate nitrogen from soil pools of both ammonium and nitrate, and the relative levels of these two nitrogen sources are highly variable in soil. Long-term ammonium nutrition is known to cause damage to Arabidopsis that has been linked to mitochondrial oxidative stress. Using hydroponic cultures, we analysed the consequences of rapid shifts between nitrate and ammonium nutrition. Thi

On the Monte Carlo Description of Hot Carrier Effects and Device Characteristics of III-N LEDs

Recent experiments have suggested that high energy charge carriers can have a significant effect on the operation of group III nitride (III-N) light-emitting diodes (LEDs), possibly playing an important role in the efficiency droop. As hot carriers are not accounted for by device simulation tools based on drift-diffusion (DD) and quasiequilibrium conditions, more advanced tools are needed. Here, f

Kinetic and mechanistic study on the reactions of ruthenium(II) chlorophenyl terpyridine complexes with nucleobases, oligonucleotides and DNA

In this study, we investigated the ability of Ru(ii) polypyridyl complexes to act as DNA binders. The substitution reactions of three Ru(ii) chlorophenyl terpyridine complexes, i.e. [Ru(Cl-Ph-tpy)(en)Cl]Cl (1), [Ru(Cl-Ph-tpy)(dach)Cl]Cl (2) and [Ru(Cl-Ph-tpy)(bpy)Cl]Cl (3) (Cl-Ph-tpy = 4′-(4-chlorophenyl)-2,2′:6′,2′′-terpyridine, en = 1,2-diaminoethane, dach = 1,2-diaminocyclohexane, bpy = 2,2′-bi

Automatic Construction of Linear Stochastic Dynamic Models For Stationary Industrial Processes with Random Disturbances Using Operating Records

We describe a new technique for automatic identification of stationary, linear systems with a single output. This class of models includes all linear, time-invariant, stochastic, difference equations driven by arbitrary inputs and having stationary, normal disturbances with rational spectra.The parameters of the model are estimated by the method of maximum likelihood. A numerical algorithm for sol

Theranostic hexosomes for cancer treatments : an in vitro study

We have formulated and investigated innovative lipid-based nanoparticles characterized by a reverse hexagonal liquid crystalline inner structure (hexosomes). These nanoparticles were doped with a potent, highly water insoluble anticancer drug, namely docetaxel, and stabilized by a mixture of commercial and folate- and rhodamine-conjugated Pluronic F108. Thus, they simultaneously possess therapeuti

Two-scale cut-and-projection convergence; homogenization of quasiperiodic structures

We demonstrate how the problem of finding the effective property of quasiperiodic constitutive relations can be simplified to the periodic homogenization setting by transforming the original quasiperiodic material structure to a periodic heterogeneous material in a higher dimensional space. The characterization of two-scale cut-and-projection convergence limits of partial differential operators is

3D skeletal uptake of 18F sodium fluoride in PET/CT images is associated with overall survival in patients with prostate cancer

Background: Sodium fluoride (NaF) positron emission tomography combined with computer tomography (PET/CT) has shown to be more sensitive than the whole-body bone scan in the detection of skeletal uptake due to metastases in prostate cancer. We aimed to calculate a 3D index for NaF PET/CT and investigate its correlation to the bone scan index (BSI) and overall survival (OS) in a group of patients w

Tracking Progress Toward EU Biodiversity Strategy Targets : EU Policy Effects in Preserving its Common Farmland Birds

Maximizing the area under biodiversity-related conservation measures is a main target of the European Union (EU) Biodiversity Strategy to 2020. We analyzed whether agrienvironmental schemes (AES) within EU common agricultural policy, special protected areas for birds (SPAs), and Annex I designation within EU Birds Directive had an effect on bird population changes using monitoring data from 39 far

Comparison of the Swedish STarT Back Screening Tool and the Short Form of the Örebro Musculoskeletal Pain Screening Questionnaire in patients with acute or subacute back and neck pain

BACKGROUND: Patients with back and neck pain are often seen in primary care and it is important to provide them with tailored interventions based on risk stratification/triage. The STarT Back Screening Tool (SBT) is a widely used screening questionnaire which has not yet been validated for a population with back and/or neck pain with short duration. Our aim was to compare the concurrent validity o

Serving 22 users in real-time with a 128-antenna massive MIMO testbed

This paper presents preliminary results for a novel 128-antenna massive Multiple-Input, Multiple-Output (MIMO) testbed developed through Bristol Is Open in collaboration with National Instruments and Lund University. We believe that the results presented here validate the adoption of massive MIMO as a key enabling technology for 5G and pave the way for further pragmatic research by the massive MIM

Hur bör entreprenörer beskattas?

Den 3:e november 2016 presenterade 3:12-utredningen sitt förslag om skärpta regler kring beskattningen av fåmansbolag. 3:12-regelverket har varit omdiskuterat och förändrats ett antal gånger sedan det infördes i samband med skattereformen 1990/91 och detta förslag är sannolikt inte det sista regelförändringsförlaget. Det kan därför finnas anledning att mer principiellt diskutera hur entreprenörska

Local volatility changes in the Black-Scholes model

In this paper we address a sensitivity problem with financial applications. Namely the study of price variations of different contingent claims in the Black-Scholes model due to changes in volatility. This study needs an extension of the classical Vega index, i.e. the price derivative with respect to the constant volatility, which we call the local Vega index (lvi). This index measures the importa

Implementation of Modern Incisional Hernia Repair Techniques

Incisional hernia is one of the most common complications (5–20%) after abdominal surgery. Surgery is the only option to cure a hernia. Symptoms of an incisional hernia depend on the size of the abdominal wall defect and the protruding tissue. About 30% of the patients with an incisional hernia will have an operation performed. Traditional surgical sutured techniques have very high recurrence rateIncisional hernia is one of the most common complications (5–20%) after abdominal surgery.
