Authors: Jin Bo , Peng Rufang , Chu Shijin , Huang Yiming , Wang Rong 
Published: September 2008

AbstractThree types of [60]fullerene crystals were obtained. The first one was the direct commercial [60]fullerene, and the other two were recrystallized from the first one in carbon bisulfide and in carbon bisulfide/petroleum ether, respectively. Scanning electron microscopy (SEM), X‐ray powder diffractometry (XRD), and FT‐IR spectrometry were used to study the physical characteristics of the crystals. The thermal stability of the three [60]fullerene crystals was studied by differential thermal analysis (DTA), and the effects of the three [60]fullerenes on the mechanical sensitivity and friction sensitivity of HMX were tested and analyzed. It was found that the three types of [60]fullerenes have different thermal stabilities, and the friction and impact sensitivities of HMX are reduced from 100% to 70% and to 60%, respectively when 1% [60]fullerene 3 was added in HMX.
Pyrotechnic Countermeasures: IV. Radiometric Performance of a Sulphur‐based Flare Composition
Authors: Koch Ernst‐Christian 
Published: September 2008

AbstractRadiometric performance of a sulphur‐based flare composition has been investigated. Composition comprising sulphur, potassium perchlorate and antimony sulphide has acceptable band ratio but an order of magnitude weaker spectral efficiency than typical carbon‐based compositions. The use of other sulphur compounds with potential for increased performance is discussed. For part III see Ref. [1].
Influence of Mg doping on the behaviour of polaronic light‐induced absorption in LiNbO3
Authors: Conradi D. , Merschjann C. , Schoke B. , Imlau M. , Corradi G. , Polgár K. 
Published: September 2008

AbstractTransient light‐induced absorption changes αli(t), caused by optically generated small polarons, are investigated in LiNbO3:Mg below and above the optical‐damage‐resistance threshold (ODRT). The lifetime of αli(t) is reduced by three orders of magnitude above the ODRT while a significantly enhanced amplitude $ \alpha ^{\rm max} _{\rm li} $ is observed in the infrared. Our observations are in full accordance with the predictions of microscopic models for the ODRT, namely the removal of NbLi antisite defects upon incorporation of Mg ions, and an enhanced dark conductivity.

Maintaining quality of fresh strawberries through various modified atmosphere packaging
Authors: Caner Cengiz , Aday Mehmet Seckin 
Published: September 2008

AbstractThe influence of various modified atmosphere packaging (MAP) (21/0.05, 4/8 and 60/20% O2/% CO2) on fresh strawberry qualities [pH, acidity, °Brix, colour (L, a) and texture profile analyses] was investigated and compared during storage.Among the gas combinations used, pH of fresh strawberry was 3.281 at 1 day, and increased to 3.561 for air [21/0.05% (O2/CO2)], 3.53 for low (4/8) and 3.538 high (60/20) at 12 days. At the end of the storage, °Brix had evolved from the initial 7.07 to 5.47, 5.65 and 5.62 for 21% O2; 4% O2 and 60% O2, respectively. Storage in 60% O2 or 4% O2 delayed the decrease of °Brix, titratable acidity and increased pH compared with 21% O2. At the end of the storage, the strawberry L values had slightly decreased.Initial values of the firmness were 1067 gf and reduced to 501 gf (21% O2); 613 gf (4% O2) and 575 gf (60% O2) at 12 days storage. Higher O2 resulted in better springiness and chewiness than those treated with 4% O2 and 21% CO2, but did not significantly affect resilience.These results show that the use of various MAP gas compositions, including high oxygen, could be a good alternative to maintain fresh strawberry qualities for at least 12 days.

The impact of satellite retrievals in a global sea‐surface‐temperature analysis
Authors: Brasnett Bruce 
Published: September 2008

AbstractAn analysis of sea surface temperature (SST) is described. It incorporates in situ observations and retrievals from one microwave and three infrared sensors. Statistical interpolation is used to update the analysis daily on a global grid with a resolution of 1/3°. The background or first‐guess field is essentially the analysis from the previous day. Satellite retrievals and buoy observations undergo a thinning and all data is subjected to a careful quality control. A scheme to remove large‐scale biases from the satellite data is included, and its impact is assessed.Analysis error is estimated using two sources of independent data with similar results. The global average r.m.s. error is less than 0.4 K. Zonally averaged errors were computed over 15°‐wide latitude bands giving errors in the range 0.25 K to 0.5 K. The contributions from infrared and microwave data are found to be roughly of equal importance. The two data types are shown to be complementary, producing a significant improvement in analysis error when used together compared with the error obtained when only one is used. The analysis also compares favourably with SST analyses produced by three other centres. Copyright © 2008 Crown in the right of Canada. Published by John Wiley & Sons, Ltd.

Authors: He Jian , Yu Quan , Li Lingfeng , Hang Wei , Huang Benli 
Published: September 2008

AbstractVarious multipole cooling cells are widely used in mass spectrometry for their outstanding performance with regard to transmission and cooling effects. Among these, radiofrequency (RF)‐only quadrupoles, hexapoles, and octopoles are routinely used in practical instrumentation. A study of their performance has been carried out using a house‐built electrospray time‐of‐flight mass spectrometer equipped with three different multipole devices. In addition, a user‐written program was developed using SIMION 7.0 to simulate ion transmission characteristics for the different devices utilized. Systematic experiments and simulations were performed with an RF‐only quadrupole, hexapole, and octopole to study their theoretical and practical characteristics.

Published: September 2008

AbstractWe have developed a new method to determine the N‐terminal amino acid sequences of proteins, regardless of whether their N‐termini are modified. This method consists of the following five steps: (1) reduction, S‐alkylation and guanidination for targeted proteins; (2) coupling of sulfo‐NHS‐SS‐biotin to Nα‐amino groups of proteins; (3) digestion of the modified proteins by an appropriate protease followed by oxidation with performic acid; (4) specific isolation of N‐terminal peptides from digests using DITC resins; (5) de novo sequence analysis of the N‐terminal peptides by matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (MALDI‐TOF MS) using the CAF (chemically assisted fragmentation) method or tandem mass spectrometric (MS/MS) analysis according to unblocked or blocked peptides, respectively. By employing DITC resins instead of avidin resins used in our previous method (Yamaguchi et al., Rapid Commun. Mass Spectrom. 2007; 21: 3329), it has been possible to isolate selectively N‐terminal peptides from proteins regardless of modification of N‐terminal amino acids. Here we propose a universal method for N‐terminal sequence analysis of proteins. Copyright © 2008 John Wiley & Sons, Ltd.
Characteristic negative ion fragmentations of deprotonated peptides containing post‐translational modifications: mono‐phosphorylated Ser, Thr and Tyr. A joint experimental and theoretical study

Published: September 2008

AbstractPeptides and proteins may contain post‐translationally modified phosphorylated amino acid residues, in particular phosphorylated serine (pSer), threonine (pThr) and tyrosine (pTyr). Following earlier work by Lehmann et al., the [M–H]− anions of peptides containing pSer and pThr functionality show loss of the elements of H3PO4. This process, illustrated for Ser (and using a model system), is CH3CONH−C(CH2OPO3H2)CONHCH3 → [CH3CONHC(CH2)CONHCH3 (−OPO3H2)] (a) → [CH3CONHC(CH2)CONHCH3–H]− + H3PO4, a process endothermic by 83 kJ mol−1 at the MP2/6‐31++G(d,p)//HF/6‐31++G(d,p) level of theory. In addition, intermediate (a) may decompose to yield CH3CONHC(CH2)CONHCH3 + H2PO in a process exothermic by 3 kJ mol−1. The barrier to the transition state for these two processes is 49 kJ mol−1. Characteristic cleavages of pSer and pThr are more energetically favourable than the negative ion backbone cleavages of peptides described previously. In contrast, loss of HPO3 from [M–H]− is characteristic of pTyr. The cleavage [NH2CH(CH2‐C6H4‐OPO3H−)CO2H] → [NH2C(CH2‐C6H4‐O−)CO2H (HPO3)] (b) → NH2CH(CH2‐C6H4‐O−)CO2H + HPO3 is endothermic by 318 kJ mol−1 at the HF/6‐31+G(d)//AM1 level of theory. In addition, intermediate (b) also yields NH2CH(CH2‐C6H4‐OH)CO2H + PO (reaction endothermic by 137 kJ mol−1). The two negative ion cleavages of pTyr have a barrier to the transition state of 198 kJ mol−1 (at the HF/6‐31+G(d)//AM1 level of theory) comparable with those already reported for negative ion backbone cleavages.

Joint modelling of longitudinal and competing risks data
Authors: Williamson P. R. , Kolamunnage‐Dona R. , Philipson P. , Marson A. G. 
Published: September 2008

AbstractAvailable methods for joint modelling of longitudinal and survival data typically have only one failure type for the time to event outcome. We extend the methodology to allow for competing risks data. We fit a cause‐specific hazards sub‐model to allow for competing risks, with a separate latent association between longitudinal measurements and each cause of failure.The method is applied to data from the SANAD trial of anti‐epileptic drugs (AEDs), as a means of investigating the effect of drug titration on the relative effects of lamotrigine (LTG) and carbamazepine (CBZ) on treatment failure. Concern had been expressed that differential titration rates may have been to the disadvantage of CBZ. The beneficial effect of LTG on unacceptable adverse events leading to drug withdrawal did not lessen and indeed increased slightly when a calibrated dose was accounted for in the joint model. Adjustment for the titration rate of LTG relative to CBZ resulted in an unchanged effect of the former on drug withdrawals due to inadequate seizure control. LTG remains the AED of choice from this analysis. Copyright © 2008 John Wiley & Sons, Ltd.
A bivariate autoregressive linear mixed effects model for the analysis of longitudinal data
Authors: Funatogawa Ikuko , Funatogawa Takashi , Ohashi Yasuo 
Published: September 2008

AbstractIn clinical studies, dependent bivariate continuous responses may approach equilibrium over time. We propose an autoregressive linear mixed effects model for bivariate longitudinal data in which the current responses are regressed on the previous responses of both variables, fixed effects, and random effects. The equilibria are modeled using fixed and random effects. This model is a bivariate extension of the model for univariate longitudinal data given by Funatogawaet al. (Statist. Med.2007;26:2113–2130). As an illustration of the approach we analyze parathyroid hormone and serum calcium measurements in the treatment of secondary hyperparathyroidism in chronic hemodialysis patients.

Connecting organizations: Developing the idea of network learning in inter‐organizational settings
Authors: White Leroy 
Published: September 2008

AbstractThe purpose of this paper is to introduce a form of analysis that is important in the development of inter‐agency working and partnerships. Social network analysis is being seen as increasingly important in understanding inter‐organizational life. The paper will introduce the idea of network learning, which is in principle a way of making social networks explicit and using an understanding of them as a part of a learning process for partnership development. The paper will also argue for a practice of network learning which integrates social network analysis with Soft Operational Research. This combination, it will be shown, provides further insights into understanding collaboration (a systems‐level phenomena) in inter‐agency networks or partnerships. These ideas will be described and reviewed in detail via a case study. Copyright © 2008 John Wiley & Sons, Ltd.
Earthquake proof efficacy of Velocity and Displacement Dependent Hydraulic Damper (VDHD) for R.C. structures
Authors: Shih Ming‐Hsiang , Sung Wen‐Pei , Chen Chang‐Liang 
Published: September 2008

AbstractThe objective of this research is to study whether a Velocity and Displacement Dependent Hydraulic Damper (VDHD) will provide effective damping without increasing the acceleration response of a reinforced concrete structure during an earthquake before the yield strength is reached. The study also includes whether this device will provide hysteretic energy after the yield strength is reached to effectively lower the structural displacement reaction. The efficiency of VDHD is confirmed using a nonlinear numerical model developed by the authors for carrying out numerical analyses of three dampers, i.e. Viscous Damper (VD), Bulking Resistant Bracing (BRB) and VDHD, to study the response of structures excited by earthquake and to compare model parameters based on their seismic performance. The results indicate that when a reinforced concrete structure is subject to near‐fault earthquake for various durations, VDHD has a better structural displacement response capability than either VD or BRB with a medium efficiency to suppress the acceleration response between VD and BRB. These observations conform to the theoretical predications thus verifying the capability of VDHD to lower the displacement and acceleration responses of a reinforced concrete structure during earthquake. The results presented in this paper illustrate the earthquake resistant capacity of VDHD to protect reinforced concrete structures. Copyright © 2008 John Wiley & Sons, Ltd.

Authors: Brient Luc , Lengronne Marion , Bormans Myriam , Fastner Jutta 
Published: September 2008

AbstractEleven waterbodies in Western France dominated by cyanobacteria of the genera Aphanizomenon and Anabaena were analyzed in September 2006 for microcystins (MC) and cylindrospermopsin (CYN). CYN was detected for the first time in France in four of them in the presence of Aphanizomenon flos‐aquae and in the presence of Anabaena planctonica in the other. The intracellular concentrations of CYN measured by LC‐MS/MS ranged between 1.55 and 1.95 μg/L. The occurrence of CYN represents an additional health hazard to MC especially because Aphanizomenon flos‐aquae is the third most common species in freshwaters in France. © 2008 Wiley Periodicals, Inc.

Published: September 2008

AbstractIn vitro cytotoxicities were measured for ionic liquids (ILs) containing various cations and anions using the MCF7 human breast cancer cell line. We measured the cytotoxicities of ionic liquids containing the cations pyridinium, pyrrolidinium, piperidinium, or imidazolium with various alkyl chain lengths, and the anions bromide, bis(trifluoromethanesulfone)imide (Tf2N), trifluoromethylsulfonate (TfO), or nonafluoromethylsulfonate (NfO). Three new hydrophobic, task‐specific ionic liquids (TSILs), namely, [MBCNPip]+[Tf2N]−, [MPS2Pip]+[Tf2N]−, and [MPS2Pyrro]+[Tf2N]− designed for metal‐ion extraction were also evaluated. IC50 values of the ionic liquids toward the MCF7 cells ranged from 8 μM to 44 mM. The toxicity depended significantly on the nature of the cations and anions, especially when the cations contained a long side chain. TSILs studied in this work were less toxic than the classical ILs. © 2008 Wiley Periodicals, Inc. Environ Toxicol, 2009.

Published: September 2008

AbstractThe integration of wireless sensor networks with different network systems gives rise to many research challenges to ensure security, privacy and trust in the overall architecture. The main contribution of this paper is a generic security, privacy and trust framework providing context‐aware adaptability, flexibility and scalability which allows customisation of wireless sensor networks to a diverse set of application spaces. Suitable protocols and mechanisms are identified, which when combined according to the framework form a complete toolbox solution which fits the architecture of Beyond 3G environments. Performance evaluation results demonstrate the feasibility and estimate the benefits of the security framework for a variety of scenarios. Copyright © 2008 John Wiley & Sons, Ltd.
Impact of wind power forecasting error bias on the economic operation of autonomous power systems

Published: September 2008

AbstractMany efforts have been presented in the literature for wind power forecasting in power systems and few of them have been used for autonomous power systems. In addition, some recent studies have evaluated the impact on the operation of power systems and energy markets that the improvement of wind power forecasting can have. In this paper, the value of the information provided to the operators of autonomous power systems about forecasting errors is studied. This information may vary significantly, e.g. it can be only the normalized mean absolute error of the forecast, or a probability density function of the errors for various levels of forecasted wind power, which can be provided either during the evaluation phase of the wind power forecasting tool or by online uncertainty estimators. This paper studies the impact of the level of detail provided about wind power forecasting accuracy for various levels of load and wind power production. The proposed analysis, when applied to the autonomous power system of Crete, shows significant changes among the various levels of information provided, not only in the operating cost but also in the wind power curtailment.

Delegated dispatching of wind farms: an optimal approach considering continuous control and interruption capabilities
Authors: Castronuovo Edgardo , Usaola Julio , Jaramillo Álvaro 
Published: September 2008

AbstractIn grids with high wind power penetration, the System Operator may curtail the power injected at critical moments for security reasons. An intermediate operator can optimize this power reduction for a group of wind farms under its control, attending to their controllability. In this way, resources may be used efficiently, and in cooperation with the system operation. In this paper, an optimization‐based procedure is proposed to allocate the power reductions among the wind farms of a region. Application examples based on the Spanish situation are shown, because in that country, these intermediate entities (called Delegated Dispatches) are about to begin their full operation.

AbstractFrom N,N′‐Bis(1,1,3‐trisila‐2‐aza)‐ethylene‐diamines to N,N′‐Bis(1,3‐disila‐2‐lithiumamido)‐ethylenesilylamines – Syntheses, Crystal Structures, ReactionsEthylenediamine reacts with the chloro‐functional tris(silyl)amines ClSiMe2N(SiMe3)SiMe2R in a molar ratio of 1:2 to give the N,N′‐bis(1,1,3‐trisila‐2‐aza)‐ethylenediamines, [CH2‐NH‐SiMe2‐N(SiMe3)SiMe2R]2, R = Me (1) and CMe3 (2). A structural isomer of 2 (CH2‐NSiMe2CMe3‐SiMe2‐NHSiMe3 = 3) is formed thermally, via 1,3‐silyl group migration from the Me3CSiMe2‐N‐SiMe3 group, at 200 °C. 1 reacts with butyllithium at 0 °C in a molar ratio of 1:2, forming the diamide 4, which was characterized as the monomer [CH2–NSiMe3–SiMe2–N(SiMe3)Li]2. Again two silyl groups migrate from the N(SiMe3)2 groups to the ethyleneamine nitrogen atoms. The lithium ions are coordinated by both amido groups forming a planar four‐membered ring. With THF as a solvent, each lithium ion of 4 coordinates one THF molecule. [CH2–NSiMe3–SiMe2–N–(SiMe3)Li–THF]2 (5) is obtained. With TMEDA as the donor base the cage structures of 4 and 5 are broken up to give an open‐chain dilithium salt [CH2–NSiMe3–SiMe2–N(SiMe3)Li–TMEDA]2 (6) with each lithium ion coordinated by one TMEDA molecule. Halosilanes and haloboranes react with 4, 5, and 6 to give an N,N′‐bis(1,1,3‐trisila‐2‐aza)‐ethylenesilylamine [CH2–NSiMe3–SiMe2–N(SiMe3)R]2, R = SiF2CMe3 (7), and N,N′‐bis(1‐bora‐1,3‐disila‐2‐aza)‐ethylenesilylamines, R = B(F)N(SiMe3)2 (8), B(F)[N(CMe2CH2)2CH2] (9).
