Development, survivorship and reproduction ofHelicoverpa armigera(Lepidoptera: Noctuidae) under fluctuating temperatures
Authors: Mironidis George K.
Published: September 2014

Laboratory studies were conducted to assess the effect of temperature on the survival, development, longevity and fecundity ofHelicoverpa armigera(Lepidoptera: Noctuidae) at eight different fluctuating temperatures with an amplitude ±9 °C under constant photoperiodic conditions of 16:8 h (L:D).H. armigeraachieved complete development from egg to adult emergence between mean 17.5 and 32.5 °C. At mean 35 °C, all newly hatched larvae died and at mean 15 °C entered diapause at pupal stage. The lower developmental thresholds of the immature stages were estimated by a linear model and ranged from 4.63 °C (pupal stage) to 7.69 °C (egg stage). The developmental thresholds estimated by a nonlinear model were slightly higher than those estimated by the linear model. Adult longevity and fecundity were reduced at mean fluctuating temperatures 17.5 and 32.5 °C, but tended to be independent of the pattern of temperature change at moderate temperatures. The maximum reproductive performance, 1130 eggs per female, was observed at mean 25 °C. The intrinsic rates of increase were positive, meaning thatH. armigeracould be expected to persist or increase in number between mean 17.5 and 32.5 °C, with the maximum value at mean 27.5 °C.H. armigerasurvives, develops and reproduces within a wide range of fluctuating temperatures, while it completes the above functions with different levels of success at different mean temperatures of diurnal variation. Comparison of our results with similar data from the literature involving constant conditions is discussed. This information will provide a better understanding ofH. armigeraphenology and population dynamics under natural conditions and is essential to understanding the ecological and evolutionary consequences of climate change on this important species.
Treatment comparisons in agricultural field trials accounting for spatial correlation
Authors: RICHTER C. , KROSCHEWSKI B. , PIEPHO H.-P. , SPILKE J.
Published: September 2014

The classical analysis model for agricultural field trials is based on the principles of experimental design – randomization, replication and blocking – and it assumes independent residual effects. Accounting for any existent spatial correlation as an add-on component may be beneficial, but it requires selection of a suitable spatial model and modification of classical tests of treatment contrasts. Using a sugar beet trial laid out in complete blocks for illustration, it is shown that tests obtained with different modifications yield diverging results. Simulations were performed to decide whether different test modifications lead to valid statistical inferences. For the spherical, power and Gaussian models, each with six different values of the range parameter and without a nugget effect, the suitability of the following modifications was studied: a generalization of the Satterthwaite method (1941), the method of Kenward and Roger (1997), and the first-order corrected method described by Kenward and Roger (2009). A second-order method described by Kenward and Roger (2009) is also discussed and detailed results are provided as Supplemental Material (available at: http://journals.cambridge.org/AGS). Simulations were done for experiments with 10 or 30 treatments in complete and incomplete block designs. Model selection was performed using the corrected Akaike information criterion and likelihood-ratio tests. When simulation and analysis models were identical, at least one of the modifications for the t-test guaranteed control of the nominal Type I error rate in most cases. When the first-order method of Kenward and Roger was used, control of the t-test Type I error rate was poor for 10 treatments but on average very good for 30 treatments, when considering the best-fitting models for a given simulation setting. Results were not satisfactory for the F-test. The more pronounced the spatial correlation, the more substantial was the gain in power compared to classical analysis. For experiments with 20 treatments or more, the recommendation is to select the best-fitting model and then use the first-order method for t-tests. For F-tests, a randomization-based model with independent error effects should be used.
Methodist Spiritual Condition in Georgian Northern England
Authors: SCHOFIELD ROBERT A.
Published: September 2014

John Wesley required detailed records to be compiled of Methodist society members. One extant list is that of the Keighley circuit for 1763–5. This article, breaking new ground in Wesley studies, argues that symbols in this and other catalogues recorded members’ spiritual condition. These symbols are used to analyse recruitment, losses and spiritual change on a quarterly basis. They reveal that although recruitment in the circuit was high during a revival at the start of a new preaching regime, it fell quickly, many members departed and there was little overall improvement in spiritual condition. Recruitment and changes were not uniform across the circuit, pointing to local rather than regional or national influences.
Pope Alexander vi, Slavery and Voluntary Subjection: ‘Ineffabilis et Summi Patris’ in Context
Authors: AVALOS HECTOR
Published: September 2014

‘Ineffabilis et summi patris’ (1 June 1497), a little-known letter from Alexander VI to Manuel i, king of Portugal (1495–1521), plays an important role in Joel Panzer's The popes and slavery (1996). For Panzer, ‘Ineffabilis’ clarifies the voluntary nature of submission by newly-encountered peoples to Iberian monarchs. A new and complete translation of ‘Ineffabilis’ shows that it is part of a legal tradition wherein voluntary subjection was one mode of enslavement. ‘Ineffabilis’ also reflects Manuel's broader attempt to gain an advantage over Spain in light of Vasco da Gama's impending voyage to India in July 1497.
Did the English Really Think They Were God's Elect in the Anglo-Saxon Period?
Authors: MOLYNEAUX GEORGE
Published: September 2014

This article challenges the contention that during the Anglo-Saxon period the English considered themselves God's specially chosen people, like the Old Testament Israelites. The texts upon which this interpretation has been based are re-analysed; particular attention is devoted to the writings of Gildas, Bede, Alcuin and Wulfstan, the prose preface of the Old English ‘Pastoral care’, and the introduction to King Alfred's legislation. The English could see themselves as a Christian people, and thus among God's chosen, but they do not appear to have claimed to be the beneficiaries of a more particularist form of divine election.
Sub-Arctic operations in the Russo-Japanese War, 1904–1905
Authors: Stone Ian R.
Published: September 2014

This note concerns the little known sub-Arctic operations in the Russo-Japanese war, 1904–1905. Apart from a slightly farcical ‘invasion’ of the Kamchatka peninsula by a group of Japanese fishermen, and a naval engagement off the coast of southern Sakhalin, the main operations related to the efficiently conducted Japanese invasion of the sub–Arctic island of Sakhalin itself. This was the only occupation of Russian territory during the war and was intended to strengthen the Japanese position in the peace negotiations, held at Portsmouth, New Hampshire, that brought the war to a close.
The distance learning of foreign languages: A research agenda
Authors: White Cynthia
Published: September 2014

Research into the distance learning of languages is now established as a significant avenue of enquiry in language teaching, with evident research trajectories in several domains. This article selects and analyses significant areas of investigation in distance language learning and teaching to identify new and emerging gaps, along with research questions, methodologies and research tools. Taken together these define a research agenda focusing on theory, pedagogy, technology use, learner contributions, innovation and less commonly taught languages. Within those broad areas, the scope of proposed research tasks includes the distinctive features and practices of distance language teaching, task design for synchronous settings, mentoring, multimodal learning environments, the transfer of speaking skills, and learners’ affective experiences. To conclude, a number of guidelines are given for future enquiry addressing the distinctive nature of research into distance language teaching and learning and the need for a rich evidence base in both theory and practice.
Versatile green: an alternative perspective on urban green space in late nineteenth-century Antwerp
Authors: TRITSMANS BART
Published: September 2014

This article argues that a one-sided focus on official sources has dominated historical research on urban green space. The absence of the users’ perspective obscures a substantial part of its significance. This article, which aims at complementing rather than contradicting existing research, will show that the different perspectives and practices of city dwellers widen our understanding of the history of urban green spaces. The article will also consider the value of often marginalized, unofficial green spaces like ramparts and wastelands at the urban fringe.

Suppose that $\def \xmlpi #1{}\def \mathsfbi #1{\boldsymbol {\mathsf {#1}}}\let \le =\leqslant \let \leq =\leqslant \let \ge =\geqslant \let \geq =\geqslant \def \Pr {\mathit {Pr}}\def \Fr {\mathit {Fr}}\def \Rey {\mathit {Re}}E$ and $E'$ denote real Banach spaces with dimension at least 2 and that $D\subset E$ and $D'\subset E'$ are domains. Let $\varphi :[0,\infty )\to [0,\infty )$ be a homeomorphism with $\varphi (t)\geq t$. We say that a homeomorphism $f: D\to D'$ is $\varphi $-FQC if for every subdomain $D_1 \subset D$, we have $\varphi ^{-1} (k_D(x,y))\leq k_{D'} (f(x),f(y))\leq \varphi (k_D(x,y))$ holds for all $x,y\in D_1$. In this paper, we establish, in terms of the $j_D$ metric, a necessary and sufficient condition for a homeomorphism $f: E \to E'$ to be FQC. Moreover, we give, in terms of the $j_D$ metric, a sufficient condition for a homeomorphism $f: D\to D'$ to be FQC. On the other hand, we show that this condition is not necessary.

Published: September 2014

In order to confirm the results of previous experiments concerning the chemical behaviour of organic molecules in the space environment, organic molecules (amino acids and a dipeptide) in pure form and embedded in meteorite powder were exposed in the AMINO experiment in the EXPOSE-R facility onboard the International Space Station. After exposure to space conditions for 24 months (2843 h of irradiation), the samples were returned to the Earth and analysed in the laboratory for reactions caused by solar ultraviolet (UV) and other electromagnetic radiation. Laboratory UV exposure was carried out in parallel in the Cologne DLR Center (Deutsches Zentrum für Luft und Raumfahrt). The molecules were extracted from the sample holder and then (1) derivatized by silylation and analysed by gas chromatography coupled to a mass spectrometer (GC–MS) in order to quantify the rate of degradation of the compounds and (2) analysed by high-resolution mass spectrometry (HRMS) in order to understand the chemical reactions that occurred. The GC–MS results confirm that resistance to irradiation is a function of the chemical nature of the exposed molecules and of the wavelengths of the UV light. They also confirm the protective effect of a coating of meteorite powder. The most altered compounds were the dipeptides and aspartic acid while the most robust were compounds with a hydrocarbon chain. The MS analyses document the products of reactions, such as decarboxylation and decarbonylation of aspartic acid, taking place after UV exposure. Given the universality of chemistry in space, our results have a broader implication for the fate of organic molecules that seeded the planets as soon as they became habitable as well as for the effects of UV radiation on exposed molecules at the surface of Mars, for example.
Millimeter-wave reconfigurable bandpass filters
Authors: Chan King Yuk “Eric” , Ramer Rodica
Published: September 2014

Millimeter-wave reconfigurable bandpass filters with the ability to operate between 60 GHz and the E-band, capable of providing good channel isolation, are presented. A fully integrated filter with all reconfigurable elements embedded for compactness and a switchable filter that uses radio frequency micro-electro-mechanical system (RF MEMS) single-pole double-throw switches are designed. A new method that increases fractional bandwidths is introduced. It uses inductively coupled inverters without requiring their tuning. New circuit models are offered for inverters, reconfigurable resonators, and reconfigurable bandstop stubs. Our compact bandpass filter achieved a footprint of only 4.75 mm × 3.75 mm. Measurements for our filters show good agreement with the results of simulations.
Compact UWB BPF using slotted resonator with an independently controllable notched band
Authors: Karimi Gholamreza , Khamin-Hamedani Farnaz , Siahkamari Hesam
Published: September 2014

In this paper, a novel compact ultra-wideband (UWB) bandpass filter (BPF) without and with one sharply notched band is presented. The UWB bandpass characteristic is achieved using slotted resonators (SR) and a notch is obtained by spiral defected ground structure (SDGS) without any change in SR structure. Center frequency of the notched band can be easily changed (from 5 to 9 GHz) by tuning the dimensions of SDGS. To verify the feasibility of the proposed filter, two UWB BPFs, one without the notched band and the other with a notched band, at 8.0 GHz are developed and fabricated, there by suppressing the spurious satellite-communication signal within passband. Measured results of two fabricated filters have the advantages of wide −3 dB bandwidth from 3.1 to 10.6 GHz (which satisfies the requirements of US Federal Communication Commission -specified UWB limits), compact size, low insertion loss (<0.6 dB), and a wide upper stopband with high attenuation (−20 to −50 dB).

Published: September 2014

In der vorliegenden Untersuchung wurde überprüft, ob standardisierte Prognoseinstrumente in der Lage sind, erneute Auffälligkeiten in einer Stichprobe von sexuell auffällig gewordenen Kindern und Jugendlichen (N = 80; als Einschlusskriterium musste keine Verurteilung erfolgt sein) vorherzusagen. Eingesetzt wurden die international als etabliert geltenden Verfahren Structured Assessment of Violence Risk in Youth (SAVRY), Estimate of Risk of Adolescent Sexual Offense Recidivism (ERASOR) und Juvenile Sex Offender Assessment Protocol-II (J-SOAP-II). Die Ergebnisse der vorliegenden Studie zeigen, dass die ursprünglich für junge bzw. jugendliche Sexualstraftäter entwickelten Instrumente auch bei einer Stichprobe sexuell auffälliger Minderjähriger in der Lage sein können, erneute auffällige Handlungen vorherzusagen. Dies gelang allerdings lediglich im Hinblick auf die allgemeine und die gewalttätige Auffälligkeit, während der Nachweis der prädiktiven Validität für erneute sexuelle Auffälligkeiten nicht gelang.

Inobhutnahmen sind zeitlich begrenzte Kriseninterventionen zum Schutz von Kindern meist in der Folge von vorhergehender Misshandlung und/oder Vernachlässigung. Die Dauer von Inobhutnahmen ist bei Säuglingen und Kleinkindern am längsten. Die mit einer längeren Trennung einhergehenden psychophysiologischen Belastungen der Kinder sowie das Vorgehen bei Inobhutnahmen werden vor dem Hintergrund der Bindungstheorie und bindungstheoretischer Forschung diskutiert. Es wird für die Entwicklung einer bindungstheoretisch begründeten Konzeption zu Verfahrensstandards und zur Gestaltung der Inobhutnahme bei Säuglingen und Kleinkindern plädiert.

Published: September 2014

Alternative splicing—the production of multiple messenger RNA isoforms from a single gene—is regulated in part by RNA binding proteins. While the RBPs transformer2 alpha (Tra2α) and Tra2β have both been implicated in the regulation of alternative splicing, their relative contributions to this process are not well understood. Here we find simultaneous—but not individual—depletion of Tra2α and Tra2β induces substantial shifts in splicing of endogenous Tra2β target exons, and that both constitutive and alternative target exons are under dual Tra2α–Tra2β control. Target exons are enriched in genes associated with chromosome biology including CHEK1, which encodes a key DNA damage response protein. Dual Tra2 protein depletion reduces expression of full-length CHK1 protein, results in the accumulation of the DNA damage marker γH2AX and decreased cell viability. We conclude Tra2 proteins jointly control constitutive and alternative splicing patterns via paralog compensation to control pathways essential to the maintenance of cell viability.
Non-commutativity and Local Indistinguishability of Quantum States
Authors: Ma Teng , Zhao Ming-Jing , Wang Yao-Kun , Fei Shao-Ming
Published: September 2014

We study the local indistinguishability problem of quantum states. By introducing an easily calculated quantity, non-commutativity, we present an criterion which is both necessary and sufficient for the local indistinguishability of a complete set of pure orthogonal product states. A constructive distinguishing procedure to obtain the concrete local measurements and classical communications is given. The non-commutativity of ensembles can be also used to characterize the quantumness for classical-quantum or quantum-classical correlated states.

Cross‐range scaling method of inverse synthetic aperture radar image based on discrete polynomial‐phase transform
Authors: Liu Lei , Zhou Feng , Tao Ming‐liang , Zhao Bo , Zhang Zi‐jing
Published: September 2014

The cross‐range scaling of inverse synthetic aperture radar image depends on both the radar wavelength and the rotating angle of the target relative to the radar line‐of‐sight. After compensating the translational motion, the second‐order phase coefficients of the range echoes are a linear polynomial of the rotating angular velocity and range geometry. In this study, a novel method for estimating the rotating angular velocity of the targets with dominant scatters is proposed. The range cells where the amplitudes have smaller normalised variances are selected, and then frequency domain windowing is applied to extract echoes of dominant scatters. Based on the discrete polynomial‐phase transform, the second‐order phase coefficients of the strong scatter echoes are estimated, and thus the rotating angular velocity can be obtained through the least‐square‐error method. Simulated and real‐data results have shown the effectiveness and robustness of this method.
Range‐dependent clutter suppression approach for non‐side‐looking airborne radar based on orthogonal waveforms
Authors: Wen Cai , Wang Tong , Wu Jian‐xin
Published: September 2014

Clutter suppression is a challenging problem in non‐side‐looking airborne radar (NSLAR) because of the range‐dependent clutter. It is more intractable when the NSLAR operates at high pulse repetition frequency (HPRF). In this study, a cascaded algorithm is presented to realise clutter suppression for NSLAR with HPRF. A novel orthogonal‐waveform‐based elevation adaptive beamforming method is proposed to suppress range‐dependent near‐range clutter at the first stage, and the residual range‐independent far‐range clutter is suppressed by azimuth‐Doppler space‐time adaptive processing (STAP) at the second stage. The proposed elevation beamformer can provide excellent performance on near‐range clutter suppression because of the developed secondary data selection strategy. After suppression of the range‐dependent near‐range clutter, the range independency of clutter samples is enhanced evidently. Hence, the clutter suppression performance obtained by azimuth‐Doppler STAP methods could be improved dramatically. Numerical examples are given to verify the validity of the proposed algorithm.

Published: September 2014

Evolutionary approach to centralized multiple-faults diagnostics is extended to distributed transducer networks monitoring large experimental systems. Given a set of anomalies detected by the transducers, each instance of the multiple-fault problem is formulated as several parallel communicating sub-tasks running on different transducers, and thus solved one-by-one on spatially separated parallel processes. A micro-genetic algorithm merges evaluation time efficiency, arising from a small-size population distributed on parallel-synchronized processors, with the effectiveness of centralized evolutionary techniques due to optimal mix of exploitation and exploration. In this way, holistic view and effectiveness advantages of evolutionary global diagnostics are combined with reliability and efficiency benefits of distributed parallel architectures. The proposed approach was validated both (i) by simulation at CERN, on a case study of a cold box for enhancing the cryogeny diagnostics of the Large Hadron Collider, and (ii) by experiments, under the framework of the industrial research project MONDIEVOB (Building Remote Monitoring and Evolutionary Diagnostics), co-funded by EU and the company Del Bo srl, Napoli, Italy.

The dependence of potential well formation on the magnetic field strength and electron injection current in a polywell device
Authors: Cornish S. , Gummersall D. , Carr M. , Khachan J.
Published: September 2014

A capacitive probe has been used to measure the plasma potential in a polywell device in order to observe the dependence of potential well formation on magnetic field strength, electron injection current, and polywell voltage bias. The effectiveness of the capacitive probe in a high energy electron plasma was determined by measuring the plasma potential of a planar diode with an axial magnetic field. The capacitive probe was translated along the axis of one of the field coils of the polywell, and the spatial profile of the potential well was measured. The confinement time of electrons in the polywell was estimated with a simple analytical model which used the experimentally observed potential well depths, as well as a simulation of the electron trajectories using particle orbit theory.
A scaled-ionic-charge simulation model that reproduces enhanced and suppressed water diffusion in aqueous salt solutions
Authors: Kann Z. R. , Skinner J. L.
Published: September 2014

Non-polarizable models for ions and water quantitatively and qualitatively misrepresent the salt concentration dependence of water diffusion in electrolyte solutions. In particular, experiment shows that the water diffusion coefficient increases in the presence of salts of low charge density (e.g., CsI), whereas the results of simulations with non-polarizable models show a decrease of the water diffusion coefficient in all alkali halide solutions. We present a simple charge-scaling method based on the ratio of the solvent dielectric constants from simulation and experiment. Using an ion model that was developed independently of a solvent, i.e., in the crystalline solid, this method improves the water diffusion trends across a range of water models. When used with a good-quality water model, e.g., TIP4P/2005 or E3B, this method recovers the qualitative behaviour of the water diffusion trends. The model and method used were also shown to give good results for other structural and dynamic properties including solution density, radial distribution functions, and ion diffusion coefficients.
Excluded volume effects in polymer brushes at moderate chain stretching
Authors: Romeis Dirk , Lang Michael
Published: September 2014

We develop a strong stretching approximation for a polymer brush made of self-avoiding polymer chains. The density profile of the brush and the distribution of the end monomer positions in stretching direction are computed and compared with simulation data. We find that our approach leads to a clearly better approximation as compared to previous approaches based upon Gaussian elasticity at low grafting densities (moderate chain stretching), for which corrections due to finite extensibility can be ignored.
A new ab initio potential energy surface and infrared spectra for the Ar–CS2 complex
Authors: Yuan Ting , Sun Xueli , Hu Yi , Zhu Hua
Published: September 2014

We report a new three-dimensional potential energy surface for Ar–CS2 involving the Q3 normal mode for the υ3 antisymmetric stretching vibration of the CS2 molecule. The potential energies were calculated using the supermolecular method at the coupled-cluster singles and doubles level with noniterative inclusion of connected triples, using augmented correlation-consistent quadruple-zeta basis set plus midpoint bond functions. Two vibrationally averaged potentials with CS2 at both the ground (υ = 0) and the first excited (υ = 1)υ3 vibrational states were generated from the integration of the three-dimensional potential over the Q3 coordinate. Each potential was found to have a T-shaped global minimum and two equivalent linear local minima. The radial discrete variable representation /angular finite basis representation method and the Lanczos algorithm were applied to calculate the rovibrational energy levels. The calculated band origin shift of the complex (0.0622 cm−1) is very close to the observed one (0.0671 cm−1). The predicted infrared spectra and spectroscopic parameters based on the two averaged potentials are in excellent agreement with the available experimental data.
Efficient anharmonic vibrational spectroscopy for large molecules using local-mode coordinates
Authors: Cheng Xiaolu , Steele Ryan P.
Published: September 2014

This article presents a general computational approach for efficient simulations of anharmonic vibrational spectra in chemical systems. An automated local-mode vibrational approach is presented, which borrows techniques from localized molecular orbitals in electronic structure theory. This approach generates spatially localized vibrational modes, in contrast to the delocalization exhibited by canonical normal modes. The method is rigorously tested across a series of chemical systems, ranging from small molecules to large water clusters and a protonated dipeptide. It is interfaced with exact, grid-based approaches, as well as vibrational self-consistent field methods. Most significantly, this new set of reference coordinates exhibits a well-behaved spatial decay of mode couplings, which allows for a systematic, a priori truncation of mode couplings and increased computational efficiency. Convergence can typically be reached by including modes within only about 4 Å. The local nature of this truncation suggests particular promise for the ab initio simulation of anharmonic vibrational motion in large systems, where connection to experimental spectra is currently most challenging.
Device and method of optically orienting biaxial crystals for sample preparation
Authors: Thomas Timothy , Rossman George R. , Sandstrom Mark
Published: September 2014

An optical instrument we refer to as the “biaxial orientation device” has been developed for finding the optical plane, acute bisectrix, and obtuse bisectrix in biaxial crystals by means of optically aligning conoscopically formed melatopes and measuring the angular coordinates of the melatopes, where the angular values allow for determination of the optical plane containing the optical axes using a vector algebra approach. After determination of the optical plane, the instrument allows for the sample to be aligned in the acute bisectrix or obtuse bisectrix orientations and to be transferred to a simple mechanical component for subsequent grinding and polishing, while preserving the orientation of the polished faces relative to the optical plane, acute bisectrix, and obtuse bisectrix during the grinding and polishing process. Biaxial crystalline material samples prepared in the manner are suitable for accurate spectroscopic absorption measurements in the acute bisectrix and obtuse bisectrix directions as well as perpendicular to the optical plane.
