Relationship between load/unload response ratio and damage variable and its application
Authors: Zhang Lang‐Ping , Yin Xiang‐Chu , Liang Nai‐Gang 
Published: October 2009

AbstractThe physics‐based parameter: load/unload response ratio (LURR) was proposed to measure the proximity of a strong earthquake, which achieved good results in earthquake prediction. As LURR can be used to describe the damage degree of the focal media qualitatively, there must be a relationship between LURR and damage variable (D) which describes damaged materials quantitatively in damage mechanics. Hence, based on damage mechanics and LURR theory, taking Weibull distribution as the probability distribution function, the relationship between LURR and D is set up and analyzed. This relationship directs LURR applied in damage analysis of materials quantitatively from being qualitative earlier, which not only provides the LURR method with a more solid basis in physics, but may also give a new approach to the damage evaluation of big scale structures and prediction of engineering catastrophic failure.

High‐Quality Covalently Grafting Hemoglobin on Gold Electrodes: Characterization, Redox Thermodynamics and Bio‐electrocatalysis
Authors: Tian Yuan , Ran Qin , Xu Jingjing , Xian Yuezhong , Peng Ru , Jin Litong 
Published: October 2009

AbstractHerein, we report a versatile surface chemistry methodology to covalently immobilize ligands and proteins to self‐assembled monolayers (SAMs) on gold electrode. The strategy is based on two steps: 1) the coupling of soluble azido‐PEG‐amimo ligand with an alkynyl‐terminated monolayer via click reaction and 2) covalent immobilization hemoglobin (Hb) to the amine‐terminated ligand via carbodiimide reaction. Surface‐enhanced Raman scattering spectroscopy (SERS), atomic force microscopy (AFM), reflection absorption infrared spectroscopy (RAIR) and cyclic voltammetry are used to characterize the model interfacial reactions. We also demonstrate the excellent biocompatibility of the interface for Hb immobilization and reliable application of the proposed method for H2O2 biosensing. Moreover, the redox thermodynamics of the Fe3+/Fe2+ couple in Hb is also investigated.
The Use of Natural Materials in Nanocarbon Synthesis
Authors: Su Dang Sheng 
Published: October 2009

AbstractNanomaterials are shifting from laboratory‐scale preparation to industrial production. The energy costs and starting materials (feedstock, catalyst, and support) consumed or used in the mass production of nanomaterials are issues that limit their broad application. Natural materials, such as sand, rock, and lava, contain small or trace amounts of metals or metal oxides of nanometer‐scale sizes and have been recently used as catalysts for the production of carbon nanotubes (CNTs), providing an interesting way to lower the production cost of CNTs. However, the sustainability of the whole production process still needs to be explored. Layered minerals (e.g., clays) are used to produce CNT–clay hybrids, which can be further used to synthesize polymer–CNT–clay nanocomposites. Natural materials and some byproducts of industrial production processes have been explored as carbon sources for nanocarbon synthesis. This Minireview highlights some recent promising work and prospects for the use of natural materials in the synthesis of CNTs, carbon nanofibers (CNFs), and nanocomposites, and their applications in catalysis and in materials science.
Variability of CD3 membrane expression and T cell activation capacity
Authors: El Hentati Fatima‐Zahra , Gruy Frederic , Iobagiu Cristina , Lambert Claude 
Published: October 2009

AbstractBackground:αβT cells have a wide distribution of CD3 membrane density. The aim of this article was to evaluate the significance of the CD3 differential expression on T cell subsets. Analysis was performed on healthy donors and renal transplant patients by flow cytometry. The results obtained are: (1) CD3 expression was widely distributed (CV = 38.3 ± 3.1 to 43 ± 2.3%). (2) The CD4, CD8, CD45 and forward scatter were similarly distributed. (3) The diversity of CD3 expression was directly related to the clonotypes: γ9, non γ9 from γδT cells and Vβ clonotype from αβT cells (e.g., Vβ3FITC 7,980 ± 1,628 Vβ8PE: Vβ20‐FITC 11,768 ± 1,510). (4) Using a computer simulation, we could confirm differential kinetics of T cell activation according to the initial parameters. Finally, in vitro activation was significantly higher on Vβ8 and Vβ9 (high CD3) compared with Vβ2 and Vβ3 (low CD3, P = 0.040–0.0003).In conclusion, T cells have highly heterogeneous CD3 expression, possibly predetermined and with clear functional significance. © 2009 Clinical Cytometry Society
CD146+ T lymphocytes are increased in both the peripheral circulation and in the synovial effusions of patients with various musculoskeletal diseases and display pro‐inflammatory gene profiles

Published: October 2009

AbstractTwenty‐eight synovial effusions (SE) were obtained from 24 patients, paired samples of peripheral blood (PB) from 10 of these patients, and PB from 36 healthy individuals for analysis of CD146 on T‐lymphocytes by flow cytometry. CD146+ or CD146− T‐lymphocytes were sorted from three SE to study gene expression profiles and selected genes revalidated using QPCR assays. We found more CD3+CD146+ and CD4+CD146+ T‐lymphocytes in PB from patients compared with PB of healthy individuals (4.71% ± 2.48% vs. 2.53% ± 1.08%, P = 0.028) and (6.29% ± 2.74% vs. 2.41% ± 0.96%, P = 0.0017), respectively, whereas CD8+CD146+ T‐lymphocytes were not significantly different (2.55% ± 1.65% vs. 3.18% ± 2.59%, P = 0.5008). SE displayed CD146 staining on 16.32% ± 6.06% of CD3+ cells. This expression was skewed toward CD4+ T‐lymphocytes, with CD146 present on 24.06% ± 8.20% of the CD4+ T‐lymphocytes compared with 6.19% ± 5.22% of the CD8+ T‐lymphocytes. CD146 on CD3+, CD4+ and CD8+ T‐lymphocytes in SE was significantly higher compared with PB in patients (P < 0.0001, P < 0.0001 and P = 0.0036, respectively). Gene expression profiles of sorted CD146+CD4+CD3+ vs. CD146−CD4+CD3+ T‐lymphocytes (n = 2) and CD2+CD146+ vs. CD2+CD 146− (n = 1) from SE, displayed increased CD146, LAIR2, CXCL13, CD109, IL6ST, IL6R, TNFRsf18, and TNFRsf4 genes, whereas decreased CCR7, CCL5, and cytotoxicity‐associated genes including granzymes b, h, and k, perforin were found with the CD146− T‐lymphocytes. By QPCR higher mRNA expression of CXCL13, CD146 and CD109 was also noted in the CD146+ subset, compared with the CD146− subset, in PB of healthy individuals and in PB and SE from patients. Our study establishes increased CD146+ T‐lymphocytes in diseases with joint effusions, and demonstrates pro‐inflammatory gene profiles in these cells. Published 2009 Wiley‐Liss, Inc.
Synthesis of Oligosaccharide Mimetics with Glycoaminoxy Acids
Authors: Gong Yanchun , Sun Hongbin , Xie Juan 
Published: October 2009

AbstractFrom readily available di‐O‐isopropylidene‐D‐glucose, a D‐ribofuranoid glycoaminoxy acid and its tBu ester have been efficiently prepared as a new family of sugar building blocks by introducing the phthalimido aminoxy group by a Mitsunobu reaction. We found that the tBu ester can be selectively deprotected with 13.7 % TFA in CH2Cl2 at 0 °C in the presence of the 1,2‐O‐isopropylidene acetal. This selective deprotection has made possible the synthesis of homo‐oligomers of glycoaminoxy acids (up to six sugar units) as a novel type of oligosaccharide mimetics. (© Wiley‐VCH Verlag GmbH & Co.

Wavelet formulation of the polarizable continuum model
Authors: Weijo Ville , Randrianarivony Maharavo , Harbrecht Helmut , Frediani Luca 
Published: October 2009

AbstractThe first implementation of a wavelet discretization of the Integral Equation Formalism (IEF) for the Polarizable Continuum Model (PCM) is presented here. The method is based on the application of a general purpose wavelet solver on the cavity boundary to solve the integral equations of the IEF‐PCM problem. Wavelet methods provide attractive properties for the solution of the electrostatic problem at the cavity boundary: the system matrix is highly sparse and iterative solution schemes can be applied efficiently; the accuracy of the solver can be increased systematically and arbitrarily; for a given system, discretization error accuracy is achieved at a computational expense that scales linearly with the number of unknowns. The scaling of the computational time with the number of atoms N is formally quadratic but a N1.5 scaling has been observed in practice. The current bottleneck is the evaluation of the potential integrals at the cavity boundary which scales linearly with the system size. To reduce this overhead, interpolation of the potential integrals on the cavity surface has been successfully used. © 2009 Wiley Periodicals, Inc. J Comput Chem, 2010
Finding a serial burglar's home using distance decay and conditional origin–destination patterns: a test of empirical Bayes journey‐to‐crime estimation in the Hague
Authors: Block Richard , Bernasco Wim 
Published: October 2009

AbstractCan we tell where an offender lives from where he or she commits crimes? Journey‐to‐crime estimation is a tool that uses crime locations to tell us where to search for a serial offender's home. In this paper, we test a new method: empirical Bayes journey‐to‐crime estimation. It differs from previous methods because it utilises an ‘origin–destination’ rule in addition to the ‘distance decay’ rule that prior methods have used. In the new method, the profiler not only asks ‘what distances did previous offenders travel between their home and the crime scenes?’ but also ‘where did previous offenders live who offended at the locations included in the crime series I investigate right now?’. The new method could not only improve predictive accuracy, it could also reduce the traditional distinction between marauding and commuting offenders. Utilising the CrimeStat software, we apply the new method to 62 serial burglars in The Hague, The Netherlands, and show that the new method has higher predictive accuracy than methods that only exploit a distance decay rule. The new method not only improves the accuracy of predicting the homes of commuters—offenders who live outside their offending area—it also improves the search for marauders—offenders who live inside their offending area. After presenting an example of the application of the technique for prediction of a specific burglar, we discuss the limitations of the method and offer some suggestions for its future development.

Sodium benzoate, potassium sorbate and sodium nitrite as silage additives
Authors: Knický Martin , Spörndly Rolf 
Published: October 2009

AbstractBACKGROUND: The hygienic quality of silage is important for animal health, animal production and food quality. The aim of this study was to evaluate the effect of five silage additive mixtures on yeast, mould, and clostridia growth and other silage quality criteria. The additives, composed of sodium nitrite, sodium benzoate and/or potassium sorbate, were used to treat a grass forage crop before ensiling. The silages were compared with untreated silage and silages treated with two commercial additives: Promyr NF (PNF), which is based on formic and propionic acid, and Kofasil Ultra (KU), a mixture of sodium nitrite, sodium benzoate, sodium propionate and hexamine.RESULTS: All tested additives significantly (P < 0.001) reduced butyric acid and ammonia‐N formation in low‐dry‐matter (DM) silages compared to the control. Only KU and the mixtures of 600 g sodium nitrite, 250 g sodium propionate, 750 g sodium benzoate (A1) and 250 g sodium nitrite with 1000 g sodium benzoate and 500 g potassium sorbate (A5) ton−1 of fresh forage were found to reduce (P < 0.001) the presence of clostridia spores in low‐DM silages. In high‐DM silages, treatments A1, A5 and A2 (250 g sodium nitrite and 1000 g sodium benzoate) contained less (P < 0.02) yeast than the control and PNF, but not KU. All treated silages were aerobically stable. The concentrations of nitrate‐N in all silages and nitrite‐N in low‐DM were below the threshold level for feed at the end of storage.CONCLUSIONS: The additive mixtures A1 and particularly A5 improved silage quality at least to the same extent as commercial products, even though they contained no hexamine and less nitrite.

Genomic expression, chemotherapy response, and molecular targets in soft tissue sarcomas of the extremities: Promising strategies for treatment selection
Authors: Aguiar Samuel , da Cunha Isabela Werneck , Lopes Ademar 
Published: October 2009

AbstractNeoadjuvant or adjuvant therapy in soft tissue sarcomas is still controversial, especially in regards to the use of chemotherapy. The identification of predictive factors is crucial to avoid the use of chemotherapy in patients with tumors that carry genetic characteristics associated with resistance. Focusing on gene expression data, we performed a review of the actual state of knowledge in molecular predictive factors for chemotherapy response and new targets of therapy in extremity sarcomas. J.

Energy‐stepping integrators in Lagrangian mechanics
Authors: Gonzalez M. , Schmidt B. , Ortiz M. 
Published: October 2009

AbstractWe present a class of integration schemes for Lagrangian mechanics, referred to as energy‐stepping integrators, that are momentum and energy conserving, symplectic and convergent. In order to achieve these properties we replace the original potential energy by a piecewise constant, or terraced approximation at steps of uniform height. By taking steps of diminishing height, an approximating sequence of energies is generated. The trajectories of the resulting approximating Lagrangians can be characterized explicitly and consist of intervals of piecewise rectilinear motion. We show that the energy‐stepping trajectories are symplectic, exactly conserve all the momentum maps of the original system and, subject to a transversality condition, converge to trajectories of the original system when the energy step is decreased to zero. These properties, the excellent long‐term behavior of energy‐stepping and its automatic time‐step selection property, are born out by selected examples of application, including the dynamics of a frozen Argon cluster, the spinning of an elastic cube and the collision of two elastic spheres.
