Changing Landscape of Moral Registers and Urban Pathology in ‘Bombay’ Cinema: Decline of Biological Family and Birth of the Individual through Awara (1951), Deewar (1951), (1975) and Satya (1998)
Authors: Kumar Akshaya 
Published: October 2011

This article attempts to map out the changing image of biological family as the central axis of collective moral imagination in Bombay Cinema. Tracing the journey of the nation through three iconic films that were massively successful and helped the nation construct its self-projection, Awara (1951), Deewar (1975), and Satya (1998), mark the birth of an individual who disengages from the epic imagination of Ramayana and Mahabharata and arrives in the dark modern metropolis of post-liberalization India, not as a star figure but in a forever exile confronting, heroically indeed, a pathological condition of his exiled larger collective.

Purpose The aim of this study is to determine clinical and ultrasound intra-operative factors related to 1-month autogenous arteriovenous fistula (AVF) thrombosis in end-stage renal failure patients. Methods A prospective study was designed, including AVF performed between October 2009 and May 2010. Patient characteristics and intra-operative measurements (clinical and ultrasound findings in both artery and vein: diameters, peak-systolic, end-diastolic and mean velocities, flow and resistance index) were recorded. At 1-month follow-up, AVF primary patency was analyzed. Stepwise logistic regression and ROC curves of the resulting test were used. Results 111 autogenous end-to-side AVF (44 radiocephalic, 45 brachiocephalic, 22 brachiobasilic) in 101 patients were performed. One-month primary patency rate was 84.7%. Intra-operative absence of bruit following skin closure could predict 1-month AVF thrombosis (70.6% sensitivity and 80.9% specificity, better than absence of thrill: 35.3% and 87.2%). However, logistic regression identified intra-operative end-diastolic velocity in the proximal feeding artery after AVF creation (EDV) as the best independent predictor of 1-month AVF thrombosis (OR=1.072, 95%CI 1.036–1.109; 76.5% sensitivity and 84.0% specificity for EDV<24.5 cm/s). This is a slight improvement on isolated clinical findings, but nevertheless a low positive predictive value (46.4%) is attained. Conclusions Prediction of AVF thrombosis with intra-operative ultrasound measurements (proximal artery EDV under 24.5 cm/s) can slightly improve isolated clinical findings, helping to establish an intra-operative criterion to review AVF and increase surgical efficiency, assuming a relatively low positive predictive value.

Authors: Sayers Stephen P. , Gibson Kyle , Cook Cristi R. 
Published: October 2011

AbstractObjectiveTo examine the effect of high‐speed power training (HSPT) on muscle performance, mobility‐based function, and pain in older adults with knee osteoarthritis.MethodsThirty‐three participants (mean ± SD age 67.6 ± 6.8 years) were randomized to HSPT (n = 12), slow‐speed strength training (SSST; n = 10), or control (CON; n = 11) for a 12‐week intervention. HSPT performed 3 sets of 12–14 repetitions at 40% of the 1‐repetition maximum (1RM) “as fast as possible,” SSST performed 3 sets of 8–10 repetitions at 80% of the 1RM slowly, and CON performed stretching and warm‐up exercises. Outcome measures included leg press (LP) 1RM and LP peak power (PP) from 40–90% of the 1RM and the corresponding PP velocity (PPV) and PP force; 400‐meter walk, Berg Balance Scale, and timed chair rise; and self‐reported function and pain using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Analysis of variance models were used to compare changes from baseline to 12 weeks. Statistical significance was accepted at P < 0.05.ResultsLP PP improved in both HSPT and SSST compared to CON (P = 0.04). LP PPV improved only in HSPT (P = 0.01). There were also improvements in timed chair rise (P = 0.002), WOMAC function (P = 0.004), and WOMAC pain (P = 0.02) across all of the groups.ConclusionHSPT was effective at improving function and pain, but no more so than either SSST or CON. Because HSPT improved multiple muscle performance measures (strength, power, and speed), it is a more effective resistance training protocol than SSST and may increase safety in this population, especially when high‐speed movements are required during daily tasks.
Improved consonant–vowel recognition for low bit‐rate coded speech
Authors: Vuppala Anil Kumar , Sreenivasa Rao K. , Chakrabarti Saswat 
Published: October 2011

SUMMARYIn this paper, we proposed a method for improving the recognition performance of 145 prominent consonant–vowel (CV) units in Indian languages for low bit‐rate coded speech. Proposed CV recognition method is carried out in two levels to reduce the similarity among a large number of CV classes. In the first level, vowel category of CV unit will be recognized, and in the second level, consonant category will be recognized. At each level of the proposed method, complementary evidences from support vector machine and hidden Markov models are combined to enhance the recognition performance. Effectiveness of the proposed two‐level CV recognition method is demonstrated by performing the recognition of isolated CV units and CV units collected from the Telugu broadcast news database. In this work, vowel onset point (VOP) is used as an anchor point for extracting accurate features from the CV unit. Therefore, a method is proposed for accurate detection of VOP in clean and coded speech. The proposed VOP detection method is based on the spectral energy in 500–2500 Hz frequency band of the speech segments present in the glottal closure region. Speech coders considered in this work are GSM full rate (ETSI 06.10), CELP (FS‐1016), and MELP (TI 2.4 kbps). Significant improvement in CV recognition performance is achieved using the proposed two‐level method compared with the existing methods under both clean and coded conditions.

Published: October 2011

AbstractProgress in the prediction and optimization of the heating of magnetic nanoparticles in an alternating magnetic field is highly desirable for their application in magnetic hyperthermia. Here, a model system consisting of metallic iron nanoparticles with a size ranging from 5.5 to 28 nm is extensively studied. Their properties depend strongly on their size: behaviors typical of single‐domain particles in the superparamagnetic regime, in the ferromagnetic regime, and of multi‐domain particles are observed. Ferromagnetic single‐domain nanoparticles are the best candidates and display the highest specific losses reported in the literature so far (11.2 ± 1 mJ g−1). Measurements are analysed using recently a demonstrated analytical formula and numerical simulations of the hysteresis loops. Several features expected theoretically are observed for the first time experimentally: i) the correlation between the nanoparticle diameter and their coercive field, ii) the correlation between the amplitude of the coercive field and the losses, and iii) the variation of the optimal size with the amplitude of the magnetic field. None of these features are predicted by the linear response theory – generally used to interpret hyperthermia experiments – but are a natural consequence of theories deriving from the Stoner–Wohlfarth model; they also appear clearly in numerical simulations. These results open the path to a more accurate description, prediction, and analysis of magnetic hyperthermia.
Charge Transport in a Highly Phosphorescent Iridium(III) Complex‐Cored Dendrimer with Double Dendrons

Published: October 2011

AbstractThe charge transporting properties of a phosphorescent iridium(III) complex‐cored dendrimer, with two dendrons attached to each ligand of the core are reported. The results show that the high photoluminescence quantum yield of this material is obtained without compromising charge transport. The hole mobility values are reported over a wide range of temperatures and electric fields using the charge‐generation layer time‐of‐flight technique. The results are analysed using the Gaussian disorder model (GDM), the correlated disorder model, the polaronic correlated disorder model, and the short‐range correlated Gaussian disorder model. It is found that the GDM model gives the most comprehensive description of hole transport in this material. In spite of its larger size, the hole mobility of the doubly dendronised material compares favourably with that of a smaller singly dendronised material, and its spherical shape leads to low energetic disorder and clearly non‐dispersive charge transport. This shows how molecular shape can be used to combine favourable photoluminescence and charge‐transporting properties.

Published: October 2011

AbstractThe heritability of attention deficit hyperactivity disorder (ADHD) is approximately 0.8. Despite several larger scale attempts, genome‐wide association studies (GWAS) have not led to the identification of significant results. We performed a GWAS based on 495 German young patients with ADHD (according to DSM‐IV criteria; Human660W‐Quadv1; Illumina, San Diego, CA) and on 1,300 population‐based adult controls (HumanHap550v3; Illumina). Some genes neighboring the single nucleotide polymorphisms (SNPs) with the lowest P‐values (best P‐value: 8.38 × 10−7) have potential relevance for ADHD (e.g., glutamate receptor, metabotropic 5 gene, GRM5). After quality control, the 30 independent SNPs with the lowest P‐values (P‐values ≤ 7.57 × 10−5) were chosen for confirmation. Genotyping of these SNPs in up to 320 independent German families comprising at least one child with ADHD revealed directionally consistent effect‐size point estimates for 19 (10 not consistent) of the SNPs. In silico analyses of the 30 SNPs in the largest meta‐analysis so far (2,064 trios, 896 cases, and 2,455 controls) revealed directionally consistent effect‐size point estimates for 16 SNPs (11 not consistent). None of the combined analyses revealed a genome‐wide significant result. SNPs in previously described autosomal candidate genes did not show significantly lower P‐values compared to SNPs within random sets of genes of the same size. We did not find genome‐wide significant results in a GWAS of German children with ADHD compared to controls. The second best SNP is located in an intron of GRM5, a gene located within a recently described region with an infrequent copy number variation in patients with ADHD. © 2011 Wiley Periodicals, Inc.
Hysteresis Compensation and Adaptive Controller Design for a Piezoceramic Actuator System in Atomic Force Microscopy
Authors: Yen Ping‐Lang , Yan Mu‐Tian , Chen Yil 
Published: October 2011

AbstractThis paper presents an indirect adaptive controller combined with hysteresis compensation to achieve high accuracy positioning control of piezoceramic actuators and illustrates the results with an atomic force microscope (AFM) application. A dynamic model of a piezoceramic actuator system in AFM is derived and analyzed. A feedforward controller based on the Preisach model is proposed to compensate for the nonlinear hysteresis effects. Then an indirect adaptive controller is designed to achieve desired tracking performance as well as deal with the uncompensated nonlinearity from hysteresis and the system parameter variation due to creep. Experimental results indicate that the proposed controller can significantly improve the positioning control accuracy of the piezoceramic actuator as well as achieve high image quality of the AFM system. The maximum scanning error was reduced from 2µm to 0.3µm in comparison with a proportional‐integral‐derivative (PID) controller.Copyright © 2011 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society
Dissipative control for a class of uncertain nonlinear control systems
Authors: Hsueh Yao‐Chu , Su Shun‐Feng , Hsiao Chih‐Ching 
Published: October 2011

AbstractA general dissipative controller is proposed to achieve robust tracking control performance for a class of uncertain single‐input single‐output (SISO) nonlinear systems. The feedback linearization technique is employed to transform the nonlinear system into an assignable inner linear system with a differential control input so that the relationship of the external (input) power and the stored energy of system can be shown clearly. Then, a dissipative controller with an assignable attenuation level is proposed to make the system energy dynamics fit a required dissipative inequality. The unstable factors of the system can then be attenuated accordingly. The system stability is guaranteed even if the system has permanent unavoidable uncertainties. The proposed design can be achieved without the use of traditional means, i.e. optimal control, which requires solution of a Hamilton inequality (or Riccati equation). The Lyapunov stable condition is assured in our approach when the system uncertainties belong to L ∞. Moreover, due to the compatibility of the proposed controller, the controller can be embedded into the designs of other controllers. In those designs, knowledge of the system functions is not required. Basically, the proposed dissipative controller is independent of the system functions. The use of the bounds of the system function is considered to prove the system stability only. Two simulations are given to illustrate the effectiveness of the proposed controller.Copyright © 2011 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society

Published: October 2011

AbstractThe objective of this study was to examine the distribution of the output power of mobile phones and other terminals connected to a 3G network in Sweden. It is well known that 3G terminals can operate with very low output power, particularly for voice calls. Measurements of terminal output power were conducted in the Swedish TeliaSonera 3G network in November 2008 by recording network statistics. In the analysis, discrimination was made between rural, suburban, urban, and dedicated indoor networks. In addition, information about terminal output power was possible to collect separately for voice and data traffic. Information from six different Radio Network Controllers (RNCs) was collected during at least 1 week. In total, more than 800000 h of voice calls were collected and in addition to that a substantial amount of data traffic. The average terminal output power for 3G voice calls was below 1 mW for any environment including rural, urban, and dedicated indoor networks. This is <1% of the maximum available output power. For data applications the average output power was about 6–8 dB higher than for voice calls. For rural areas the output power was about 2 dB higher, on average, than in urban areas.

Published: October 2011

AbstractWireless mobile phones and other telecommunication devices are used extensively in daily life. We therefore examined the effects of combined exposure to radiofrequency electromagnetic fields (RF‐EMF) on rat testicular function, specifically with respect to sensitive processes such as spermatogenesis. Male rats were exposed to single code division multiple access (CDMA) and wideband code division multiple access (WCDMA) RF signals for 12 weeks. The RF exposure schedule comprised 45 min/day, 5 days/week for a total of 12 weeks. The whole‐body average specific absorption rate (SAR) of CDMA and WCDMA was 2.0 W/kg each or 4.0 W/kg in total. We then investigated the correlates of testicular function such as sperm count in the cauda epididymis, testosterone concentration in the blood serum, malondialdehyde concentrations in the testes and epididymis, frequency of spermatogenesis stages, and appearance of apoptotic cells in the testes. We also immunoblotted for p53, bcl2, GADD45, cyclin G, and HSP70 in the testes of sham‐ and combined RF‐exposed animals. Based on the results, we concluded that simultaneous exposure to CDMA and WCDMA RF‐EMFs at 4.0 W/kg SAR did not have any observable adverse effects on rat spermatogenesis.

A modified IMAC method for the capture of target protein from mammalian cell culture harvest containing metal chelating species
Authors: Zhang Aming , Zhang Cheng , Warikoo Veena , Forstrom Jonathan , Riske Frank 
Published: October 2011

AbstractAlthough immobilized metal affinity chromatography (IMAC) offers high capacity and protein selectivity it is not typically used commercially for the capture of native proteins from mammalian cell culture harvest. This is due mainly to the potential for low target recovery due to the presence of strong metal ion chelating species in the harvest that compete for the metal immobilized on the resin. To address this issue a buffer exchange step, such as tangential flow filtration (TFF), is added after harvest clarification and prior to IMAC to remove the interfering harvest components. The addition of a TFF step adds process time and cost and reduces target protein recovery. The elimination of the TFF might make IMAC competitive with other orthogonal methods of protein capture. In this study, we developed a modified IMAC method to allow the direct loading of clarified mammalian harvest without prior buffer exchange (direct IMAC). Although the target enzyme recovery was lower than that from standard IMAC the elimination of the buffer exchange step resulted in a 19% increase in overall enzyme recovery. The target enzyme capacity in direct IMAC was higher, in our experience, than the capacity of hydrophobic interaction (HIC) and ion‐exchange (IEX) for protein capture. An economic evaluation of using direct IMAC as a capture step in manufacturing is also discussed. Biotechnol. Bioeng. 2012; 109:747–753. © 2011 Wiley Periodicals, Inc.
Increasing the Reactivity of Nitrogen Catalysts
Authors: De Rycke Nicolas , Couty François , David Olivier R. P. 
Published: October 2011

AbstractThis review article presents how nitrogen‐centred Lewis bases were modified in order to increase their reactivity in catalytic processes. As examples, we focus on alcohol acylation and Morita–Baylis–Hilman reactions in order to showcase the fundamental parameters at play in transformations initiated by catalysts bearing respectively an active sp2 or sp3 nitrogen atoms. These two aspects are epitomised by two leading compounds, the Steglich base 4‐dimethylaminopyridine (DMAP), and 1,4‐diazabicyclo[2.2.2]octane (DABCO). Throughout this review, we stress the role played and the information brought by physical organic chemistry. Comprehension of these complex transformations relies on the fundamental knowledge of parameters, such as, nucleophilicity, nucleofugality, Lewis basicity, and crucially also the knowledge of their divergent impacts on each elementary step of the catalytic cycle.
System‐Dependent Dispersion Coefficients for the DFT‐D3 Treatment of Adsorption Processes on Ionic Surfaces
Authors: Ehrlich Stephan , Moellmann Jonas , Reckien Werner , Bredow Thomas , Grimme Stefan 
Published: October 2011

AbstractDispersion‐corrected density functional theory calculations (DFT‐D3) were performed for the adsorption of CO on MgO and C2H2 on NaCl surfaces. An extension of our non‐empirical scheme for the computation of atom‐in‐molecules dispersion coefficients is proposed. It is based on electrostatically embedded M4X4 (MNa, Mg) clusters that are used in TDDFT calculations of dynamic dipole polarizabilities. We find that the ${C_6^{MM} }$ dispersion coefficients for bulk NaCl and MgO are reduced by factors of about 100 and 35 for Na and Mg, respectively, compared to the values of the free atoms. These are used in periodic DFT calculations with the revPBE semi‐local density functional. As demonstrated by calculations of adsorption potential energy curves, the new C6 coefficients lead to much more accurate energies (Eads) and molecule–surface distances than with previous DFT‐D schemes. For NaCl/C2H2 we obtained at the revPBE‐D3(BJ) level a value of Eads=−7.4 kcal mol−1 in good agreement with experimental data (−5.7 to −7.1 kcal mol−1). Dispersion‐uncorrected DFT yields an unbound surface state. For the MgO/CO system, the computed revPBE‐D3(BJ) value of Eads=−4.1 kcal mol−1 is also in reasonable agreement with experimental results (−3.0 kcal mol−1) when thermal corrections are taken into account. Our new dispersion correction also improves computed lattice constants of the bulk systems significantly compared to plain DFT or previous DFT‐D results. The extended DFT‐D3 scheme also provides accurate non‐covalent interactions for ionic systems without empirical adjustments and is suggested as a general tool in surface science.
Vaporization Enthalpies of Imidazolium Based Ionic Liquids: Dependence on Alkyl Chain Length

Published: October 2011

AbstractVaporization enthalpies of a series of ten 1‐alkyl‐3‐methylimidazolium bis(trifluoromethanesulfonyl)imide ionic liquids (ILs) [Cnmim][NTf2] with alkyl chain lengths of n=2, 3, 4, 6, 8, 10, 12, 14, 16, and 18 are determined by using a recently developed quartz crystal microbalance method. Due to the high sensitivity of the microbalance vapor studies can be extended to temperatures 60–100 K lower than those available with other methods. The results reveal a remarkably linear dependence of the vaporization enthalpies on the chain length at the reference temperature of 298 K.
