A recursive algorithm by Aho et al. [SIAM J. Comput., 10 (1981), pp. 405-421] forms the basis for many modern rooted supertree methods employed in Phylogenetics. However, as observed by Bryant [Building Trees, Hunting for Trees, and Comparing Trees: Theory and Methods in Phylogenetic Analysis, Ph.D. thesis, University of Canterbury, Christchurch, New Zealand, 1997], the tree output by the algorith
Purpose – To identify and describe the strategic potential of logistics-driven packaging innovation in retail supply chains, and suggest propositions for further research and development, providing practitioners with a better basis on which to make strategic packaging and logistics decisions. Design/methodology/approach – An in-depth case study was conducted at a large global retailer which had im
A 'cap and dip' method of adsorbing ruthenium di-2,2'-bipyridy1-4,4'-dicarboxylic acid diisocyanate (N3 dye) on a rutile TiO2 (110) surface was investigated using pyrocatechol as a capping molecule. This method involves cleaning the rutile surface in ultra-high vacuum (UHV), depositing pyrocatechol onto the surface to 'cap' the adsorption sites, removing from vacuum, 'dipping' in an N3 dye solutio
The Mo2B2Fe-type intermetallic compounds Gd2Cu2In and Gd2Cu2Mg form a complete set of solid solutions Gd2Cu2In1-xMgx. The a lattice parameter, the Weiss constant and the Curie temperature increase with increasing magnesium content in an almost Vegard-like manner, while the c parameter remains almost constant. All members of the solid solutions show ferromagnetism with T(C)s between 114 and 80 K.
In this paper, we present a novel approach for the design of rate-maximizing channel shortening detectors with soft feedback side information for frequency-selective channels. The detector is a soft-input soft-output detector and constitutes one of the components of an iterative receiver. The design optimization is performed from an information-theoretic perspective where we maximize the achievabl
We study simulated annealing algorithms to maximise a function psi on a subset of R-d. In classical simulated annealing, given a current state theta(n) in stage n of the algorithm, the probability to accept a proposed state z at which psi is smaller, is exp(-beta(n+1)(psi(z) - psi (theta(n))) where (beta(n)) is the inverse temperature. With the standard logarithmic increase of (beta(n)) the probab
The resolution and fidelity of global chronostratigraphic correlation are direct functions of the time period under consideration. By virtue of deep-ocean cores and astrochronology, the Cenozoic and Mesozoic time scales carry error bars of a few thousand years (k.y.) to a few hundred k. y. In contrast, most of the Paleozoic time scale carries error bars of plus or minus a few million years (m. y.)
Background: Patients with idiopathic carpal tunnel syndrome (CTS) are commonly treated with steroid injection into or proximal to the carpal tunnel. However, evidence for its efficacy beyond one month has not been established in randomized placebo-controlled trials. The primary aim of this randomized trial is to assess the efficacy of steroid injection into the carpal tunnel in relieving symptoms
The first objective was to investigate if intracellular and extracellular levels of reactive oxygen species (ROS) within the mouse aorta increase before or after diet-induced lesion formation. The second objective was to investigate if intracellular and extracellular ROS correlates to cell composition in atherosclerotic lesions. The third objective was to investigate if intracellular and extracell
Måltiderna ska lösas intellektuellt, praktiskt och emotionellt. Flera gånger varje dag. Hur hittar unga familjer matinspiration under vardagens tidspress? Och hur klarar de vardagens ”hot spot” mellan 17 och 18? Att handla mat och komponera vardagens måltider är en ständigt pågående problemlösningsprocess. Den som har ansvaret behöver idéer, inte alltid nyskapande och dramatiska, men ändå någon
The use of electron probes for in situ imaging of solution phase systems has been a long held objective, largely driven by the prospect of atomic resolution of molecular structural dynamics relevant to chemistry and biology. Here, we present a nanofluidic sample cell with active feedback to maintain stable flow conditions for pathlengths varying from 45 nm to several 100 nm, over a useable viewing
