Visualizing the Planimetric Accuracy of Historical Maps with MapAnalyst
Authors: Jenny Bernhard , Weber Adrian , Hurni Lorenz
Published: June 2007

MapAnalyst is a new software application for the visualization and study of the planimetric accuracy of old maps. It illustrates local map distortion by generating distortion grids, displacement vectors, and new isolines of scale and rotation. MapAnalyst additionally computes the old map's scale and rotation, as well as statistical indicators summarizing the map's geometric accuracy. It offers a user-friendly interface and is freely available for all major computer platforms at . Map historians are invited to use MapAnalyst, and are encouraged to consult and improve the free Java source-code.

This article describes the steps leading to visualizations of a map's planimetric accuracy. It provides basic algorithmic information that is necessary for the understanding and correct interpretation of displacement vectors and distortion grids. It also introduces isolines of equal scale and rotation, a new type of accuracy visualization. The last section interprets sample visualizations for an eighteenth century map.

Published: June 2007

Recent studies on electrophosphorescent polymeric devices have demonstrated that charge‐trapping‐induced direct recombination on the phosphorescent dopant is of crucial importance. In this paper, we show that the electrochemical properties of phosphorescent molecules, which reflect their carrier‐trapping ability, may be a basic design criterion for the selection of host and device configuration. The systems, consisting of a red phosphorescent [Ru(4,7‐Ph2‐phen)3]2+ dopant and two blue hosts 2‐biphenyl‐4‐yl‐5‐(4‐tert‐butyl‐phenyl)‐[1,3,4]oxadiazole (PBD) and poly(vinylcarbazole) (PVK), are intensively studied. The triplet energy level of PVK and PBD is higher than that of the [Ru(4,7‐Ph2‐phen)3]2+, and both hosts show the ability of efficient energy transfer to the dopant, however, efficient electroluminescence (EL) is only obtained in the PVK‐host system. The combined studies of photoluminescence (PL), EL, and electrochemistry for doped films demonstrate that [Ru(4,7‐Ph2‐phen)3]2+, which undergoes a multielectron trapping process as it is used as a dopant in electron‐rich (n‐type) hosts, for instance, PBD, may induce an inefficient recombination for the resulting emission. Whereas using a hole‐rich (p‐type) polymer, such as PVK, as a host and inserting both hole‐blocking and electron‐transfer layers can effectively increase the efficiency of the corresponding devices up to 8.63 Cd A–1, because of the reduced probability of multielectron trapping at the [Ru(4,7‐Ph2‐phen)3]2+ sites.
Improved multiple‐particle tracking for studying flows in multiphase systems
Authors: Yang Z. , Fan X. , Fryer P. J. , Parker D. J. , Bakalis S.
Published: June 2007

Positron Emission Particle Tracking is a powerful and noninvasive technique and has been successfully used in a wide range of fundamental research and industrial applications. However, it is only capable of following a single tracer. This article presents a Multiple‐Positron Emission Particle Tracking technique for tracking two freely moving particles in opaque systems and its application. The developed technique has been validated through tracking two stationary particles and two moving particles, respectively. The results showed that it is a reliable technique and can be potentially used to acquire more comparative information, such as the interactions and relative motions of particles with different sizes, densities, and material textures in multiphase systems. Tracking two polyethylene particles, labeled using 18F, in a cylindrical fluidized bed has been given as an example. The information obtained provides significant insights into phenomena in flow and mixing processes. © 2007 American Institute of Chemical Engineers AIChE J, 2007

Glycine transporter (GlyT)‐1 plays a pivotal role in maintaining the glycine level at the glutamatergic synapse. Glycine is an allosteric agonist ofN‐methyl‐D‐aspartate (NMDA) receptors. Because activation of NMDA receptors is an essential step for induction of methamphetamine dependence and psychosis, differences in the functioning of GlyT‐1 due to genetic variants of theGlyT‐1gene (GLYT1) may influence susceptibility. A case‐control genetic association study of theGLYT1gene examined 204 patients with methamphetamine‐use disorder and 210 healthy controls. We examined three single nucleotide polymorphisms (SNPs), SNP1, IVS3 + 411C > T, rs2486001; SNP2, 1056G > A, rs2248829; and SNP3, IVS11 + 22G > A, rs2248632, of theGLYT1gene and found that SNP1 showed a significant association in both genotype (P = 0.0086) and allele (P = 0.0019) with methamphetamine‐use disorder. The T‐G haplotype at SNP1 and SNP2 was a significant risk factor for the disorder (P = 0.000039, odds ratio: 2.04). The present findings indicate that genetic variation of theGLYT1gene may contribute to individual vulnerability to methamphetamine dependence and psychosis. © 2007 Wiley‐Liss, Inc.
Portal vein embolization before major hepatectomy and its effects on regeneration, resectability and outcome
Authors: Ribero D , Abdalla E K , Madoff D C , Donadon M , Loyer E M , Vauthey J-N
Published: June 2007

Background

This study evaluated the safety of portal vein embolization (PVE), its impact on future liver remnant (FLR) volume and regeneration, and subsequent effects on outcome after liver resection.

Methods

Records of 112 patients were reviewed. Standardized FLR (sFLR) and degree of hypertrophy (DH; difference between the sFLR before and after PVE), complications and outcomes were analysed to determine cut-offs that predict postoperative hepatic dysfunction.

Results

Ten (8·9 per cent) of 112 patients had PVE-related complications. Postoperative complications occurred in 34 (44 per cent) of 78 patients who underwent hepatic resection and the 90-day mortality rate was 3 per cent. A sFLR of 20 per cent or less after PVE or DH of not more than 5 per cent (versus sFLR greater than 20 per cent and DH above 5 per cent) had a sensitivity of 80 per cent and a specificity of 94 per cent in predicting hepatic dysfunction. Overall, major and liver-related complications, hepatic dysfunction or insufficiency, hospital stay and 90-day mortality rate were significantly greater in patients with a sFLR of 20 per cent or less or DH of not more than 5 per cent compared with patients with higher values.

Conclusion

DH contributes prognostic information additional to that gained by volumetric evaluation in patients undergoing PVE.
New Sequences, Constituents, and Producers of Peptaibiotics: An Updated Review
Authors: Degenkolb Thomas , Kirschbaum Jochen , Brückner Hans
Published: June 2007

To date, 18 genera of imperfect and ascomycetous fungi have been recognized to produce ca. 700 individual sequences of peptaibiotics. These are linear polypeptide antibiotics which i) have a molecular weight between 500 and 2,200 Dalton, thus containing 5–21 residues; ii) show a high content of α‐aminoisobutyric acid; iii) are characterized by the presence of other nonproteinogenic amino acids and/or lipoamino acids; iv) possess an acylated N‐terminus, and v) have a C‐terminal residue that, in most of them, consists of a free or acetylated amide‐bonded 1,2‐amino alcohol, but might also be an amine, amide, free amino acid, 2,5‐dioxopiperazine, or sugar alcohol. From April 2003 until present, ca. 300 new individual sequences of peptaibiotics have been published in the literature, but most of them have not yet been included in databases. To summarize these new sequences and novel constituents, as well as to introduce fungal species hitherto unknown as producers of peptaibiotics, the relevant literature is reviewed. Furthermore, ecophysiological and taxonomic aspects of the producing fungi are discussed.
Peptaibiomics: Microheterogeneity, Dynamics, and Sequences of Trichobrachins, Peptaibiotics from Trichoderma parceramosumBissett (T. longibrachiatumRifai)
Authors: Krause Corina , Kirschbaum Jochen , Brückner Hans
Published: June 2007

From the culture broth of the filamentous fungus Trichoderma parceramosum, strain CBS 936.69, a mixture of polypeptide antibiotics (pepaibiotics), named trichobrachin (TB), was isolated. Three major groups designated TB I, TB II, and TB III could be separated and isolated by preparative TLC on silica gel. Individual peptides of these three groups were sequenced by on‐line LC/ESI‐MSn. The mixture of N‐acetylated peptides comprises ten 19‐residue peptides with a free C‐terminal Gln residue (TB I peptides), two 18‐residue peptides with a free C‐terminal Gln residue (TB II 1 and 2), seven 20‐residue peptides with a C‐terminal amide‐bound phenylalaninol (TB II 3–10), and 34 eleven‐residue peptides with either a C‐terminal leucinol or isoleucinol or valinol (TB III 1–34). Monitoring production and degradation of peptaibiotics in a pilot experiment revealed that the biosynthesis of TB II and TB III peptides starts two days after the beginning of fermentation. After five days of fermentation, the concentration of TB II decreased, whereas the amount of TB I increased. This observation unequivocally demonstrates that those two 18‐residue TB I and TB II peptides with the free carboxy terminus result from enzymatic C‐terminal degradation of the 20‐residue TB II peptides. In analogy to the technical terms proteome and proteomics, the terms peptaibiome and peptaibiomics have recently been proposed for the entirety and dynamics of the Aib‐containing peptides (comprehensively named peptaibiotics). Consequently, the entire peptaibiome of T. parceramosum grown under submerse conditions in shake‐flasks for five days comprises at least 54 peptides differing in main‐chain length and microheterogeneity, i.e., exchange of amino acids and the C‐terminal 1,2‐amino alcohol.
Flow Regime Transitions in an Internal‐Loop Airlift Reactor
Authors: Fu C.‐C. , Fan L.‐S. , Wu W.‐T.
Published: June 2007

The flow regime transitions of the riser and downcomer in an internal‐loop airlift reactor are investigated. Analysis of the effects of mean value, standard deviation and chaotic time series on pressure fluctuation signals is recorded to determine the transition of the hydrodynamics in the riser and downcomer of the internal‐loop airlift reactor. Two major chaotic invariants, the correlation dimension and the largest Lyapunov exponent, are employed to indicate the regime transitions. The regime transitions are determined by the sudden increase and decrease of the chaotic invariants, which are computed by the pressure fluctuation signals obtained by varying the gas flow velocity. The determination of chaotic invariants predicts that there is no heterogeneous phase existing in the downcomer of the internal‐loop airlift reactor. The experimental observations agree well with the predicted results.
Cobalt‐Mediated [2+2+2] Cycloaddition versus CH and NH Activation of 2‐Pyridones and Pyrazinones with Alkynes: A Theoretical Study
Authors: Aubert Corinne , Gandon Vincent , Geny Anaïs , Heckrodt Thilo J. , Malacria Max , Paredes Elisa , Vollhardt K. Peter C.
Published: June 2007

DFT computations have been executed aimed at illuminating the variety of pathways by which pyridones react with alkynes in the presence of [CpCoL2]: NH‐2‐pyridones furnish N‐dienylated ligands (NH activation pathway), N‐methyl‐2‐pyridones are converted into ligated cyclohexadienes ([2+2+2] cocycloaddition pathway), and N‐alkynyl‐2‐pyridones may undergo either [2+2+2] cocycloaddition or C‐dienylation (CH activation), depending on the length of the tether. The calculations predict the formation of the experimentally observed products, including their regio‐ and stereochemical make up. In addition, the unusual regiochemical outcome of the all‐intramolecular [2+2+2] cycloaddition of N,N′‐dipentynylpyrazinedione was rationalized by computation, which led to the discovery of a new mechanism.
Application of the Intramolecular Isomerisation–Aldolisation from Allylic Alcohols and Allylic Silyl Ethers to the Synthesis of Indanones and Indenones
Authors: Petrignet Julien , Roisnel Thierry , Grée René
Published: June 2007

A new access to indanones was discovered through a one‐step nickel or iron‐mediated transposition of 2‐hydroxyisobenzofurans. Starting from the corresponding silylenol ethers, a new one‐pot tandem isomerisation–Mukaiyama aldol process was also developed. These versatile strategies will be useful for the preparation of various types of indanones and indenones.
