Managing Slow‐Moving Perishables in the Grocery Industry
Authors: Ketzenberg Michael , Ferguson Mark E. 
Published: December 2008

We address the value of information and value of centralized control in the context of a two‐echelon, serial supply chain with one retailer and one supplier that provide a single perishable product to consumers. Our analysis is relevant for managing slow‐moving perishable products with fixed lot sizes and expiration dates of a week or less. We evaluate two supply chain structures. In the first structure, referred to as decentralized information sharing, the retailer shares its demand, inventory, and ordering policy with the supplier, yet both facilities make their own profit‐maximizing replenishment decisions. In the second structure, centralized control, incentives are aligned and the replenishment decisions are coordinated. The latter supply chain structure corresponds to the industry practices of company‐owned stores or vendor‐managed inventory. We measure the value of information and value of centralized control as the marginal improvement in expected profits that a supply chain achieves relative to the case when no information is shared and decision making is decentralized. Key assumptions of our model include stochastic demand, lost sales, and fixed order quantities. We establish the importance of information sharing and centralized control in the supply chain and identify conditions under which benefits are realized. As opposed to previous work on the value of information, the major benefit in our setting is driven by the supplier's ability to provide the retailer with fresher product. By isolating the benefit by firm, we show that sharing information is not always Pareto‐improving for both supply chain partners in the decentralized setting.
INTRA- AND INTER-ITERATION 3D OSEM PET IMAGE RECONSTRUCTION
Authors: Jeng Wei-Min , Hsu Yu-Liang 
Published: December 2008

Most of the recent medical imaging modalities use noninvasive means to obtain the activity information inside human organs, so doctors may detect the initial symptoms of a disease as early as possible and give appropriate treatment. PET is to use radio-isotopes which can emit positrons in its clinical and research uses. By injecting the nuclear medicine drug formed by labeling a radioelement to molecules of deoxidized glucose to a patient and after the cells in the patient body absorbing it through metabolic functions, the detectors will receive annihilation coincidence events formed from the number of the positrons generated from the response of the labeled deoxidized glucose molecules. The most critical module of the modality therefore is the procedure regarding how to reconstruct good quality images using the collected projection information. However, in the reconstruction process, MLEM involves massive data in considerable number of iterations in order to yield accurate images and takes quite a long time in computation. Ordered Subsets Expectation Maximization (OSEM) was proposed to accelerate the reconstruction process by expediting the convergence while maintaining the same image quality as those produced by MLEM. Since then, OSEM iterative algorithm has become the de facto reconstruction method adopted by most PET installations. To further improve the image quality, both clinical and research data have been acquired in 3D mode on the majority of the current systems. The accompanied computational load of iterative reconstruction increases considerably resulting from the 3D OSEM method. Attributed to the fact of the recent technological advancement, many high-performance parallel methods have been proposed to speed up the reconstruction process. These methods in general are to partition data into several sets before applying any parallel acceleration. They do not take on the nature of OSEM method to identify the intrinsic data dependencies. This project intends to analyze the iterative natures of the 3D OSEM method, particularly the intra- and inter-iteration aspects of the reconstruction method along with the latest shared-memory parallel machine architecture. Experiments will be conducted to demonstrate its superior performance over the existing methods.
Double Homologation Method for Substituted Soluble Pentacenes and Dimerization Behaviours of Pentacenes
Authors: Li Shi , Li Zhiping , Nakajima Kiyohiko , Kanno Ken‐ichiro , Takahashi Tamotsu 
Published: December 2008

AbstractDouble up: A zirconium‐mediated double homologation method was successfully applied for the synthesis of multi‐substituted pentacene derivatives from 1,2,4,5‐tetrakis(propargyl)benzenes. The bis(zirconacyclopentadiene) intermediates were also characterized. Among these symmetrical derivatives, tetra‐ and octa‐substituted pentacenes undergo reversible conversion between monomeric and dimeric forms.magnified imageA double homologation method for the formation of substituted soluble pentacenes was developed by a zirconium‐mediated cyclization of tetrayne derivatives. Thermal dimerization of tetra‐ and octasubstituted pentacenes was observed. The dimerization behavior was observed to be strongly related to the substituent groups affixed to the pentacenes.
Water Soluble Cruciforms: Effect of Surfactants on Fluorescence
Authors: Tolosa Juan , H. F. Bunz Uwe 
Published: December 2008

AbstractBrighten up! Adding surfactants to aqueous solutions of three different water‐soluble cruciforms (XF) improves their fluorescence quantum yields. Additionally, changes are observed in the emission wavelength of the XF around the critical micelle concentration (cmc) of the surfactant.magnified imageThree 1,4‐bis‐(aminostyryl)‐2,5‐bis(phenylethynyl) benzenes carrying four, six, or eight acetic acid units were investigated for their surfactochromicity. Anionic, cationic, and nonionic surfactants as well as a surfactant‐like protein (bovine serum albumin, BSA) were added to buffered solutions of the XFs in water, causing—in most cases—the fluorescence quantum yield to increase significantly and a blue‐ or red‐shifted emission to be observed. The addition of cationic (cetyltrimethylammonium bromide, CTAB) and neutral (Brij 35, TWEEN 20 and Triton X‐100) surfactants to XFs causes a red shift in their emission at low or very low surfactant concentrations that we attribute to surfactant‐induced excimer formation. The fluorescence quantum yield is in most cases a monotonous function of surfactant concentration. For the investigated ionic surfactants, the fluorescence quantum yield of the XFs does not change much after the critical micelle concentration (CMC) of the surface is reached. However, in the case of non‐ionic surfactants, the fluorescence quantum yields of the XFs starts to increase after the CMC has been reached, suggesting that different effects are involved.
Malaria fördert genetische Vielfalt in Endemiegebieten

Published: December 2008

AbstractProteinvarianten, deren Funktion beeinträchtigt ist, bieten gelegentlich einen unerwarteten Überlebensvorteil, indem sie vor Infektionskrankheiten schützen. Deshalb treten bestimmte Erbkrankheiten in Endemiegebieten gehäuft auf. Eine normalerweise nachteilige Veränderung im Stoffwechsel der Entzündung schützt beispielsweise die Erstgeborenen von malariainfizierten Müttern.
Immunologische Nachweisverfahren: ELISA
Authors: Schrödel Andrea 
Published: December 2008

AbstractMit immunologischen Nachweisverfahren können sowohl Krankheitserreger als auch bestimmte Proteine nachgewiesen werden, die bei Krankheiten als spezifische Biomarker gelten. Weitere bekannte Anwendungsgebiete für diese Tests sind beispielsweise Schwangerschafts‐, Drogen‐ sowie Dopingtests. Alle diese Verfahren haben gemeinsam, dass der Nachweis durch eine Antigen‐Antikörperreaktion geschieht, wobei je nach Konfiguration des Testsystems sowohl Antigen als auch Antikörper der nachzuweisende Analyt sein können.
Chiralität: Überkreuz mit links und rechts
Authors: Quadbeck‐Seeger H.‐J. 
Published: December 2008

AbstractDie Wissenschaft wirkt wie das Scheidewasser: Es löst und entfernt alles, nur das übrig bleibende Gold hat Bestand. Das Gold ist die Wahrheit. So ließe sich im alchemistischen Stil definieren. Tatsächlich ist die Wissenschaft der einzige Tätigkeitsbereich der Menschheit, in dem nur die überprüfbare, objektive Wahrheit zählt. Betrug wird irgendwann aufgedeckt, falsche Hypothesen gehen unter und Fehler müssen korrigiert werden. Unachtsamkeiten werden erkannt. Von einer solchen ist hier zu berichten.
Rearrangement of N‐Aryl‐2‐Vinylaziridines to Benzoazepines and Dihydropyrroles: A Synthetic and Theoretical Study
Authors: Fantauzzi Simone , Gallo Emma , Caselli Alessandro , Piangiolino Cristiana , Ragaini Fabio , Re Nazzareno , Cenini Sergio 
Published: December 2008

AbstractHerein we report the one‐pot synthesis of several N‐heterocyclic compounds by rearrangement reactions of N‐aryl‐2‐vinylaziridines. The optimization of the synthetic methodology employed allowed us to obtain differently substituted 2,5‐dihydro‐1H‐benzo[b]azepines in good yields and purities. The relationship between the nature of the starting N‐aryl‐2‐vinylaziridine and the obtained N‐heterocycle was also investigated. Finally, to rationalize all the experimental results reported in this paper a theoretical study was performed that casts light on the reaction mechanism.
Enantioselective Iridium‐Catalyzed Allylic Arylation
Authors: Polet Damien , Rathgeb Xavier , Falciola Caroline A. , Langlois Jean‐Baptiste , El Hajjaji Samir , Alexakis Alexandre 
Published: December 2008

AbstractWe describe herein the development of the first iridium‐catalyzed allylic substitution using arylzinc nucleophiles. High enantioselectivities were obtained from the reactions, which used commercially available Grignard reagents as the starting materials. This methodology was also shown to be compatible with halogen/metal exchange reactions. Its synthetic potential is demonstrated by its application towards the formal synthesis of (+)‐sertraline.
