Pricing and timing of consolidated deliveries in the presence of an express alternative: Financial and environmental analysis

Shipment consolidation has been advocated by researchers and politicians as a means to reduce cost and improve environmental performance of logistics activities. This paper investigates consolidated transport solutions with a common shipment frequency. When a service provider designs such a solution for its customers, she faces a trade-off: to have the most time-sensitive customers join the consol

Does a long-term oscillation in nitrogen concentration reflect climate impact on submerged vegetation and vulnerability to state shifts in a shallow lake?

Various ecosystems, including shallow lakes, are suggested to possess alternative stable state dynamics. The response of such systems to environmental change is non-linear and not fully reversible, which calls for identification of feedback mechanisms and subtle changes connected to structural stability. Here, we used a 25-year data series on water chemistry to make inferences on processes prior t

Progression of mild Alzheimer's disease: knowledge and prediction models required for future treatment strategies.

Introduction: Knowledge of longitudinal progression in mild Alzheimer’s disease (AD) is required for the evaluation of disease-modifying therapies. Our aim was to observe the effects of long-term cholinesterase inhibitor (ChEI) therapy in mild AD patients in a routine clinical setting. Methods: This was a prospective, open-label, non-randomised, multicentre study of ChEI treatment (donepezil, riva

National Incidence and Prevalence of TSH-Secreting Pituitary Adenomas in Sweden.

Context:TSH-secreting pituitary adenomas (TSHomas) are rare. Epidemiological data are scant and there are no reports on national incidence.Objective:The objective of the study was to estimate the national Swedish incidence and prevalence of TSHomas.Design:This was an observational study.Setting:The study was conducted at tertiary referral centers.Patients:The Swedish Pituitary Registry and World H

An evaluation of monitoring possibilities of argatroban using rotational thromboelastometry and activated partial thromboplastin time

Background: Rotational thrombelastometry/thrombelastography with ROTEM (R) and TEG (R) is becoming available bedside in an increasing number of intensive care units, where many patients with heparin-induced thrombocytopenia (HIT) are treated. The study has been performed in an effort to find out whether ROTEM (R) could be an alternative to activated partial thromboplastin time (aPTT) when argatrob

Topics in Complex Analysis and Operator Theory I. The shift operator on spaces of vector-valued analytic functions II. Fatou-type theorems for general approximate identities III. Preduals of Q_p-spaces

This thesis consists of six articles on three different subjects in the area of complex analysis, operator theory and harmonic analysis. Part I - "The Shift Operator on Spaces of Vector-valued Analytic Functions" consists of three closely connected articles that investigate certain operators in the Cowen-Douglas class with spectrum D - the unit disc, or equivalently, the shift operator M_z

Urinary cotinine in children and adults during and after semiexperimental exposure to environmental tobacco smoke

Urinary cotinine (U-cotinine) as a biomarker of environmental tobacco smoke exposure was evaluated in 14 children (age 4-11 y) and in 7 adults who were exposed to environmental tobacco smoke at an air nicotine level of 110 mg/m3 for 2 h in a bus. Nicotine in air and U-cotinine were measured by gas chromatography/mass spectrometry before, during, and after the experiment. U-cotinine rose rapidly to

A Grammar of Makalero : A Papuan Language of East Timor

This work is the first comprehensive description of Makalero, a language spoken by approximately 6,500 speakers in the Iliomar subdistrict, in the south-east of the Republic of East Timor. While previous sources considered it to be a dialect of the larger language Makasae, the present study, which is based on primary data gathered by the author during fieldwork in East Timor, notes sufficient gram

Injury markers predict time to dementia in subjects with MCI and amyloid pathology.

OBJECTIVES: Alzheimer disease (AD) can now be diagnosed in subjects with mild cognitive impairment (MCI) using biomarkers. However, little is known about the rate of decline in those subjects. In this cohort study, we aimed to assess the conversion rate to dementia and identify prognostic markers in subjects with MCI and evidence of amyloid pathology. METHODS: We pooled subjects from the VU Un

Event Prediction and Bootstrap in Time Series

Alarm systems are used in many situations, and should be as efficient as possible. In this thesis optimal predictive alarm systems, event predictors, are presented for general linear time series models with external signals. This family of process models include e.g. AR, ARMA, ARMAX and Box-Jenkins-type models. An optimal alarm system is characterized by having the least number of false alarms, fo

Continuous amplitude-integrated electroencephalogram predicts outcome in hypothermia-treated cardiac arrest patients.

OBJECTIVE:: To assess the prognostic value of continuous amplitude-integrated electroencephalogram in comatose survivors after cardiac arrest and treated with hypothermia. DESIGN:: Prospective observational study. SETTING:: General intensive care unit at a university hospital. PATIENTS:: Comatose patients after cardiac arrest and treated with hypothermia. INTERVENTIONS:: Patients were sedated and

Real-time prostate-specific antigen detection with prostate-specific antigen imprinted capacitive biosensors

Prostate specific antigen (PSA) is a valuable biomarker for early detection of prostate cancer, the third most common cancer in men. Ultrasensitive detection of PSA is crucial to screen the prostate cancer in an early stage and to detect the recurrence of the disease after treatment. In this report, microcontact-PSA imprinted (PSA-MIP) capacitive biosensor chip was developed for real-time, highly

New constraints on the evolution of 87Sr/86Sr of seawater during the Upper Triassic

The Late Triassic time interval witnessed several important biological turnovers, extinctions and onset of new life forms. Therefore, it is crucial to better constrain the tectonic, climatic and oceanographic framework at this time. The radiogenic strontium isotopic composition (87Sr/86Sr) of seawater, recorded in marine carbonates is sensitive to variations in continental weathering and oceanic s

Long-Term Risk of Hip Complications After Radiation Therapy for Prostate Cancer : A Dose-Response Study

Purpose: The aim of the present study was to analyze the long-term incidence of hip complications after external beam radiation therapy compared with age-matched controls from the general population. We also investigated whether there were any dose−response associations. Methods and materials: A total of 349 patients with prostate cancer treated to curative dose with external beam radiation therap

Plasma VEGF-D and sFLT-1 are potential biomarkers of hemodynamics and congestion in heart failure and following heart transplantation

BackgroundInflammation and tyrosine-kinases are known mediators in the pathobiology of cardiovascular disease. Plasma biomarkers reflecting these systems may provide a noninvasive complement reflecting hemodynamics, aiding in clinical decision-making. We therefore aimed to investigate the plasma levels of vascular and inflammatory proteins, and their associations with invasive hemodynamics in adva
