Estimation of kinetic parameters is a key step in modelling, as direct measurements are often expensive, time-consuming or even infeasible. The class of dynamic models in polynomial form is particularly relevant in systems biology and biochemical engineering, as those models naturally arise from modelling biochemical reactions using for instance mass action, Michaelis-Menten or Hill kinetics. Often the parameters are not uniquely identifiable for a given model structure and measurement set. Thus the question of which parameters are consistent or inconsistent with the data arises naturally. Here we present a method capable of proving inconsistency of entire parameter regions with the data. Based on the polynomial representation of the system, we formulate a feasibility problem that can be solved efficiently by semi-definite programming. The feasibility problem allows us to check consistency of entire parameter regions by using upper and lower bounds on the parameters. This drastically limits the search space for subsequent parameter estimation methods. In contrast to similar approaches in the literature, the here presented approach does not require a steady state assumption. Measurements at discrete time points are used, but neither regular sampling intervals, nor a time discretisation of the system is required. Measurement uncertainties are dealt with using upper and lower bounds on the measured states. [less ▲]

Hurricane winds affect the flow around electrical conductor in a way that it may reach the critical (Drag crisis) and postcritical states. It is thus important to introduce the cable aerodynamic drag as Reynolds-dependent when calculating the response of the power transmission line under hurricane. To represent the respective wind loading on cable, the turbulent, spatially non-uniform wind model is used. In order to assess the behaviour and cyclic fatigue loads under hurricane conditions of different transmission line conductors, the time response analyses were done. Results of comparative study of the smooth cable AERO-Z and classical multistrand cable, including the percentage of load reduction offered to supporting structure, are presented. [less ▲]

Spectroscopic mode identification techiques, which monitor intensity variations across an absorption line, provide the possibility of determining the quantum numbers l and m, the inclination and the intrinsic pulsation amplitude of a star. Of course, the uncertainties of the mode identification are dependent on the quality of the observations and the identification method applied. We have focused on the Pixel-by-pixel method/Direct line profile fitting (Mantegazza 2000) and the Moment method (Balona 1987, Briquet & Aerts 2003) for pinpointing mode parameters and tested the impact of various observational effects and stellar properties on the identification.

This article is part of a volume on limits of competition law. It explores a particular type of limitations, which has not recieved the attention it deserves. These limits stem from finite legal technology and bear on imports from economics into competition law. There is usually more than one way to import any given element of economic wisdom into a court decisions, but there is a finite number of options. Therefore, courts who are willing to take on an economic arguments will have to make choices as to the most suited legal technique among those available. In this article, I offer a typology of available legal techniques and explain their respective characteristics in terms of three characteristics, which matter for importing economics: degree of legal change implied, flexibility and fidelity to economic reasoning. I argue that it is important that courts become aware of the choice-of-technique decisions they are making and that scholars consider this methodological dimension of competition law & economics.

LiMn2-xTixO4 compounds with 0.5 =<x =< 1 were prepared by solid state reaction and Pechini technique. Powder X-ray diffraction showed that all samples crystallize with the spinel crystal structure (S.G. Fd3m). The cubic unit-cell parameter increases with the Ti content. The influence of the Ti content and cationic distribution on the magnetic properties of the compounds was studied by measuring the temperature and magnetic field dependences of the magnetization: substitution by non-magnetic d(0) Ti4+ ions appeared to weaken the magnetic interactions between the manganese ions. The electrical properties of LiMnTiO4 were studied by AC impedance spectroscopy and DC polarisation measurements, which revealed the electronic character of the conduction process.

Very little is known about the higher latitude inland biology of continental Antarctica. In this paper we describe the limnology and biology of the Dufek Massif, using a range of observational, microscopic and molecular methods. Here two dry valleys are home to some of the southernmost biota on Earth. Cyanobacteria were the dominant life forms, being found in lakes and ponds, in hypersaline brines, summer melt water, relict pond beds and in exposed terrestrial habitats. Their species diversity was the lowest yet observed in Antarctic lakes. Green algae, cercozoa and bacteria were present, but diatoms were absent except for a single valve; likely windblown. Mosses were absent and only one lichen specimen was found. The Metazoa included three microbivorous tardigrades (Acutuncus antarcticus, Diphascon sanae and Echiniscus (cf) pseudowendti) and bdelloid rotifer species, but no arthropods or nematodes. These simple faunal and floral communities are missing most of the elements normally present at lower latitudes in the Antarctic which is probably a result of the very harsh environmental conditions in the area.

A theoretical study of the lithium intercalated LiMSO(4)F and deintercalated MSO(4)F systems, where M = Fe, Co and Ni has been performed within the framework of density functional theory. Beyond predictions of structural evolution and average voltages versus a lithium electrode, we have applied partial density of states and Bader's topological analysis of the electron density to the study of lithium deintercalation. Upon lithium extraction, charge rearrangement occurs for nickel between different d-orbitals, but with little net positive charge gain, while cobalt and iron atoms end up with a clear oxidized state. The participation of oxygen ions in accepting the electron of the lithium is thus enhanced for LiNiSO(4)F. However, this effect does not affect the long-range electrostatic interactions a lot in the lithiated phase, since the valence of all transition metals is very close due to initial lower oxidized state for the Ni atom in the host. It is found that this is not essentially a long-range electrostatic interaction within the lithiated phase but within the host which explains, at least partly, the increase in voltage by passing from Fe to Ni. Our results also shed light upon the possibility of getting an approximate evaluation of the local strain associated with delithiation from the atomic volume evolutions, which are also likely to affect the electrochemical potential.

Introduction: Dipeptidyl peptidase-4 (DPP-4) inhibitors offer new options for the management of type 2 diabetes (T2DM). The novel compound linagliptin has important different pharmacokinetic (PK) properties, when compared with previously commercialized DPP-4 inhibitors, which may offer some advantages in clinical practice. Linagliptin has a unique PK/pharmacodynamic (PD) profile and is the first DPP-4 inhibitor with a nonrenal elimination route. Therefore, it can be administered in patients with renal impairment without dose adjustment or monitoring of renal function. The drug has a low potential for drug-drug interactions (DDIs) and no clinically relevant ones were reported so far. Areas covered: An extensive literature search was performed to analyse primarily PK and secondarily PD characteristics of linagliptin in both healthy volunteers and patients with T2DM (treated with linagliptin as monotherapy or combined therapy). Updated information about linagliptin PK either after single administration (large dose range) or after chronic administration (steady state) were also included. A special focus has been put on DDIs and on PK/PD of linagliptin in patients with renal impairment. Expert opinion: Head-to-head comparative studies and/or increased clinical experience with DPP-4 inhibitors will determine the clinical advantage, if any, of one agent over another. [less ▲]

INTRODUCTION: The first-choice drug therapy in the management of type 2 diabetes is metformin . However, most patients require a combined therapy to reach and/or maintain targets of glucose control. Dipeptidyl peptidase-4 (DPP-4) inhibitors, commonly referred to as gliptins, offer new options for combined therapy with metformin. Linagliptin is the most recently launched gliptin, with a unique pharmacokinetic (PK) profile characterized by negligible renal excretion and is now also available as a fixed-dose combination (FDC) with metformin. AREAS COVERED: An extensive literature search was performed to analyze the potential PK and pharmacodynamic interactions between linagliptin and metformin. Linagliptin and metformin may be administered together, either separately or as FDC supported by bioequivalence studies. Linagliptin and metformin are not prone to PK drug-drug interactions. Their coadministration improves blood glucose control more potently than either compound separately, without hypoglycemia and without increasing metformin-related gastrointestinal side effects. EXPERT OPINION: The combination linaglitpin plus metformin, if not contraindicated (renal failure), may be used as first-line or second-line therapy in the management of type 2 diabetes. That being said, the durability of the glucose-lowering effect of this combination needs to be further explored in long-term controlled trials. [less ▲]
