Switching Plasmon Resonances by Polarization of the Incident Light in Metamolecules

We numerically demonstrate the modulation of plasmon resonances in a metamolecule composed of metal bars and L-shaped nanoparticles by using the finite difference time domain method. Due to the dependence of electromagnetic coupling on polarization of the incident light, we show that the superradiant and subradiant states can be switched from ON and OFF resonantly. These two resonances are continuously adjustable as the polarization angle of incident wave changes. This feature reveals a possibility of dynamically switching the coupled plasmon resonances of an artificial microstructure and to construct functional metamaterials, which is helpful for nanophotonic devices such as filters and optical switches.
Treatment planning intercomparison for spinal chordomas using intensity-modulated photon radiation therapy (IMRT) and carbon ions

Spinal chordomas cannot be treated with an effective dose using conventional radiation therapy (RT) without exceeding the tolerance dose of the spinal cord while ensuring sufficient target coverage at the same time. In this study we investigate the potential physical advantages of combined photon intensity-modulated radiation therapy (IMRT) and raster-scanned carbon ion RT over photon IMRT alone. For a representative patient we generated a carbon ion RT plan and a photon IMRT plan. Additionally, combined plans consisting of both carbon ions and photon IMRT were calculated using ratios of 20:40 GyE, 30:30 GyE and 40:20 GyE. The best target coverage was obtained using carbon ions alone. Using a combination of photon IMRT and carbon ions, the target coverage was better than with photon IMRT alone. Due to the applied dose constraints, the sparing of the spinal cord was comparable for all plans. Using carbon ions alone, the non-target tissue volume irradiated to at least 30 GyE/50.4 GyE was reduced by 72%/84% compared to photon IMRT alone. These advantages were evident even with combined techniques. The actually delivered dose distribution is expected to be more dependent on patient misalignment with carbon ions compared with photon IMRT. A combination of carbon ions and photon IMRT might be preferable in order to profit by the physical advantages of carbon ions while ensuring a safe treatment.
Negative spectral index of fNL in the axion-type curvaton model

We derive the spectral index of fNL and its running from isocurvature single field and investigate the curvaton models with a negative spectral index of fNL in detail. In particular, a numerical study of the axion-type curvaton model is illustrated, and we find that the spectral index of fNL is negative and its absolute value is maximized around σ* = πf/2 for the potential V(σ) = m2f2(1−cos (σ/f)). The spectral index of fNL can be 𝒪(−0.1) for the axion-type curvaton model. A convincing detection of a positive nfNL will rule out the axion-type curvaton model. In addition, we also give a general discussion about the detectable parameter space for the curvaton model with a polynomial potential.
Teaching a Robot Pick and Place Task using Recurrent Neural Network

Programming a robot to perform a specific task is generally time consuming. This paper proposes a novel method to teach new task to a robot. The main contribution is the idea of building a task planner based on a Recurrent Neural Network (RNN). The neural network learns how to plan a task from observing a task sequence generated from a general motion planner. The method is evaluated by teaching pick and place tasks to a Baxter robot. The experiences are performed in a physical simulator. It shows that the robot can adapt to pick and place an object in various initial positions.
Device characteristics of GaAs-based heterojunction bipolar transistors using an InGaAs/GaAsP strain-compensated layer as a base material

An InGaAs/GaAsP strain-compensated layer has been proposed as a base material for GaAs-based double heterojunction bipolar transistors (DHBTs). As known, decreasing bandgap energy of the base layer in heterojunction bipolar transistors (HBTs) can result in a smaller turn-on voltage. Using InGaAs as a base material is one possible approach to achieve the aim. However, compressive strain induced by InGaAs diminishes the influence of indium-adding-induced bandgap energy reduction, and thus abates the advantage of turn-on voltage reduction. In this study, a 280 Å GaAs0.81P0. 19 layer has been inserted below the In0.054Ga0. 946As base layer to compensate the compressive strain induced by the InGaAs base layer. The result shows that the utilization of an InGaAs/GaAsP strain-compensated layer results in a reduction of the turn-on voltage by 20 mV. A turn-on voltage reduction of 190 mV over a conventional HBT with a GaAs base layer is achieved by utilizing the In0.054Ga0. 946As/GaAs0.81P0. 19 strain-compensated base layer. This particular DHBT has a small offset voltage of 55 mV and a knee voltage of 0.6 V. A peak current gain of 58.98, a unity-current-gain cut-off frequency fT of 22 GHz and a unilateral power gain cut-off frequency fMAX of 25 GHz are also achieved for this particular DHBT.
Ballistic magnetoresistance?

We review the published work on electric transport in metallic magnetic nanocontacts of sizes reaching a single atom. Considering fabrication methods exempt from mechanical instabilities, we find two experimental consensuses in magnetoresistance measurements. Firstly, magnetoresistance does not exceed a few tens of per cent in atomic size constrictions. We attribute these modest values to the significant number of opened conduction channels expected in contacts of 3D metals. Secondly, anisotropic magnetoresistance is observed for all types of samples, with amplitudes at least one order of magnitude larger than those found in bulk samples. Abrupt resistance changes with field angle confirm the occurrence of discrete anisotropic magnetoresistance levels. The effect is attributed to enhanced spin–orbit coupling at the atomic scale, resulting in possible opening or closure of conductance channels when varying the angle between current and applied magnetic field.
Constituent Quark Rest Energy and Wave Function Across the Light Cone

It is shown that for a constituent quark in the intra-nucleon self-consistent field the spin-orbit interaction lowers the quark rest energy to values $\sim100$ MeV, which agrees with the DIS momentum sum rule. The possibility of violation of the spectral condition for the light-cone momentum component of a bound quark is discussed.
Optimum sampling parameters for generalized holographic stereograms

It is well known that unproper sampling of discrete perspective images can result in readily visible artifacts. Previous work has used partial coherence theory to calculate the characteristics of sampled perspective imaging in the case where the viewer's pupil coincides with the perspective window. I now apply the same formalism to treat the general case where the viewer position is independent of the perspective window. This allows the theory to be used in the treatment of generalized holographic stereograms (ultragrams) and other unconventional geometries.
Impact of self-irradiation damage on the aqueous durability of zircon (ZrSiO4): implications for its suitability as a nuclear waste form

Zircon has been proposed as a nuclear waste form to safely encapsulate weapons-grade plutonium. In order to study the impact of self-irradiation damage in zircon on its aqueous durability, we performed a hydrothermal experiment (2 M CaCl2 solution, 600 °C, 100 MPa) with several variably radiation-damaged, i.e. amorphized, zircon samples. We found an anomalous increase in the alteration rate at two critical concentrations of amorphous domains. The first dramatic increase sets in when the amorphous domains form interconnected clusters in the structure. The second increase is related to the percolation of fast diffusion pathways consisting of nano-sized regions of depleted matter that are formed during strongly overlapping α-recoil events, as seen by molecular-dynamics simulations and small-angle x-ray scattering measurements. The two percolation thresholds provide model benchmarks for the safety performance of a zircon waste form.
A Usability Evaluation of the BMW Active Cruise Control System With “Stop and Go” Function

While adaptive cruise control (ACC) systems have been broadly few studies have investigated the user experience characteristics of recent production systems. The present study was designed for the express purpose of testing one such system. Nineteen participants drove a 2014 BMW X-5 M, equipped with adaptive cruise control, in two scenarios designed to be representative of the usage scenarios described by the vehicle manufacturer. During testing, user interactions with the system were recorded while opinions regarding the usability and operation of the system were elicited through a series of interviews and questionnaires. While participants responded favorably to the system conceptually, participants expressed considerable dissatisfaction with the ACC’s braking behavior and with specific aspects of the system’s user interface. These findings add to a growing body of research that suggests that mode confusion or insufficient awareness of system status may be a significant impediment to the use of ACC systems generally.
Structure and mechanics of single biomolecules: experiment and simulation

One of the main goals of molecular biology is to understand the structure of biomolecules. With the emergence of single molecule manipulation techniques that structure can now be controlled by the application of stretching and torsional stresses. In this article we review some recent experiments on the stretching and twisting of single biopolymers, testing the elastic properties of DNA and proteins and studying their stress-induced structural transitions. Numerical simulations have emerged as a precious tool to interpret the experimental data and predict the associated structural changes. We shall explain how a combination of these experimental and computational tools open a new vista on the structure of biomolecules.
Quantum Fisher Information of Driven Multi-particle Systems in Structured Bosonic Reservoirs

We investigate the dynamics of the precision of the parameter estimation in many driven atoms, each of which interacts with a local structured bosonic reservoir respectively. The evolution of quantum states for single driven atom is described by the time local quantum master equation. The dynamics of the quantum Fisher information for many entangled atoms is obtained by means of the supreoperator mapping. The estimation limit is superior to the standard quantum limit during a characteristic interval. At a given time, the precision of parameter estimation can be improved to a maximal value if the number of entangled atoms is chosen to be an optimal value. The optimal number of entangled atoms is determined by the dynamical property. The decay of quantum Fisher information is accelerated with the increase of the number of entangled atoms.
Supported scheduling of unmanned vehicles for military operations

The role of military operators is changing towards supervision of multiple unmanned vehicles. This places new demands on the operators that require supportive systems. This study focused on the design of a system to support the user to allocate high-level tasks to unmanned vehicles for military operations and that respects the objectives and restrictions of the user. The domain analysis resulted in an abstraction decomposition space for the domain and nine proposals of patterns for interaction design. This includes a method to align the user and system objectives and to provide additional transparency of the system about a proposed schedule’s compliance with the user objectives. The effect of the additional transparency was investigated in a user study using a prototype of the system on user performance, situational awareness (SA), trust and cognitive task load. However, there was insufficient statistical power to conclude that the additional transparency, compared to a condition without additional transparency, nor the order of these conditions, had a direct or interaction effect on the participants, except for a learning effect on SA. Besides other interesting effects, the experiment showed that the order of the conditions with and without additional transparency had an effect on the use of it and a positive attitude of participant towards the system resulted in automation-induced compliance.
Torsion rationnelle des modules de Drinfeld

Cette these etudie l'existence de points de torsion pour les modules de Drinfeld de rang 2 sur des extensions finies de F_q(T), pour q puissance d'un nombre premier. Notre approche suit celle de Mazur et Merel pour la torsion des courbes elliptiques sur les corps de nombres : nous introduisons un quotient de la jacobienne d'une courbe modulaire de Drinfeld, defini a l'aide d'un symbole modulaire de Teitelbaum particulier, et etudions ses proprietes. Sous une hypothese de dualite entre algebre de Hecke et formes modulaires pour F_q[T], ainsi qu'une hypothese technique mineure, on montre le resultat suivant : s'il existe un module de Drinfeld de rang 2 sur une extension de degre au plus q de F_q(T), muni d'un point de torsion d'ordre un ideal premier n de F_q[T], alors le degre de n est au plus max(q,4). Nous utilisons pour cela une description de l'action de l'algebre de Hecke sur les symboles modulaires de Teitelbaum et sur les formes modulaires pour F_q[T]. Lorsque le degre de n est petit, on obtient des resultats non conditionnels : il n'existe aucun module de Drinfeld de rang 2 sur une extension de degre au plus 2 (resp. au plus 3) de F_q(T) possedant un point de torsion d'ordre un ideal premier de degre 3 (resp. de degre 4 si q est au moins 7). Cela confirme partiellement une conjecture de Poonen et Schweizer de borne uniforme sur la torsion des modules de Drinfeld.
A review of adjustable lenses for head mounted displays

Adjustable lens technology has the potential to improve Head Mounted Displays (HMDs) through style and comfort by providing optical prescription correction and focussing mechanisms integrated within the HMD. It can also reduce simulator sickness and user experience of 3D through resolution of Vergence Accommodation Conflict, and age-related user problems (presbyopia). We review the available technology and the design constraints to show how a fluid filled lens may be appropriate for AR and MR, and an Alvarez lens may be appropriate for VR.
Clique partitions and coverings of graphs

This essay looks at the clique partition and covering numbers of graphs and introduces some new results. In the first part, two cornerstone theorems in clique partitions are presented and proved. Namely, the Erdős-Goodman-Pósa Theorem and the de Bruijn-Erdős Theorem. The problem of partitioning the complement of a clique is looked at, and asymptotic results are provided. The existence of Steiner systems and projective planes can be used to construct clique partitions of complements of graphs. Using Steiner systems, upper bounds on the clique partition number of the complement of paths, cycles, and perfect matchings are given. For the first time, we provide an upper bound for the clique partition number of the complement of a forest and the complement of graphs with bounded maximum degree. In the second part, the clique covering number of the complement of small graphs is analyzed. We provide results by Kohayakawa of induced paths and cycles in the Kneser graph. Bounds on the clique covering number of the complement of a path and cycle are given. Also, the clique covering number of the complement of a perfect matching is determined, a result of Gregory and Pullman. By using the Erdős-KoRado Theorem, we are able to generalize this result to obtain a lower bound on the clique covering number for complete multipartite graphs. The clique covering number of the complement of the union of cycles and paths is looked at, and we demonstrate that in general, a lower bound of log2 n cannot be obtained. Finally, for the first time, we obtain bounds on the clique covering number of the complement of a forest.

Flow equations and new weak-coupling solution for the spin-polaron in a quantum antiferromagnet

The t-J model for the doped two-dimensional Heisenberg quantum antiferromagnet is studied in the generalized Dyson-Maleev representation, applying a new continuous unitary transformation which eliminates the coupling of spin and charge degrees of freedom. The analytical solutions of the resulting flow equations are derived in the weak-coupling regime where t/J is small. This continuous transformation yields a new weak-coupling result for the dispersion of the spin-polaron, if the elimination of both the non-diagonal spin-wave contributions and the terms coupling holes and spin-waves is performed simultaneously. The associated one-particle ground state is lower in energy than the corresponding perturbative result, which is reproduced upon application of subsequent transformations.
DUST AND THE TYPE II-PLATEAU SUPERNOVA 2004et

We present mid-infrared (MIR) observations of the Type II-plateau supernova (SN) 2004et, obtained with the Spitzer Space Telescope between 64 and 1406 days past explosion. Late-time optical spectra are also presented. For the period 300–795 days past explosion, we argue that the spectral energy distribution (SED) of SN 2004et comprises (1) a hot component due to emission from optically thick gas, as well as free–bound radiation; (2) a warm component due to newly formed, radioactively heated dust in the ejecta; and (3) a cold component due to an IR echo from the interstellar-medium dust of the host galaxy, NGC 6946. There may also have been a small contribution to the IR SED due to free–free emission from ionized gas in the ejecta. We reveal the first-ever spectroscopic evidence for silicate dust formed in the ejecta of a supernova. This is supported by our detection of a large, but progressively declining, mass of SiO. However, we conclude that the mass of directly detected ejecta dust grew to no more than a few times 10−4 M☉. We also provide evidence that the ejecta dust formed in comoving clumps of fixed size. We argue that, after about two years past explosion, the appearance of wide, box-shaped optical line profiles was due to the impact of the ejecta on the progenitor circumstellar medium and that the subsequent formation of a cool, dense shell was responsible for a later rise in the MIR flux. This study demonstrates the rich, multifaceted ways in which a typical core-collapse supernova and its progenitor can produce and/or interact with dust grains. The work presented here adds to the growing number of studies that do not support the contention that SNe are responsible for the large mass of observed dust in high-redshift galaxies.
Economic evaluation of sol–gel based film coating scheme for HTS materials

Under the sponsorship of the US Department of Energy (USDOE), the University of Tennessee Space Institute (UTSI) carried out an engineering evaluation of various options to manufacture long lengths of high-temperature superconductor (HTS) wire/tape. As a result, the leading candidates to apply buffer and/or YBCO (HTS) materials were identified as based on metal organic decomposition (MOD), sol–gel, metal organics chemical vapour deposition (MOCVD) and pulsed laser deposition (PLD). Earlier, Chapman had developed economics for manufacturing schemes based on MOCVD, e-beam and PLD. Using his approach, preliminary economics for a sol–gel based manufacturing scheme has been estimated. In this paper, major findings from our economic evaluation of the sol–gel based film coating scheme are reported.
Surface measurement and fractal characterization of naturally fractured rocks

A method of stylus measurement of fractured rock surfaces over relatively long sample lengths is described, together with methods of characterizing the fracture structure. Surface topography results are presented and analysed in several ways, including the use of 'fractal' methods, which show that naturally fractured rock can be classified as self-affine fractals and require two parameters, fractal dimension and topothesy for characterizing these naturally fractured rocks.
Pulsed Ion Sheath Dynamics in a Cylindrical Bore for Inner Surface Grid-Enhanced Plasma Source Ion Implantation

Based on our recently proposed grid-enhanced plasma source ion implantation (GEPSII) technique for inner surface modification of materials with cylindrical geometry, we present the corresponding theoretical studies of the temporal evolution of the plasma ion sheath between the grid electrode and the target in a cylindrical bore. Typical results such as the ion sheath evolution, time-dependent ion density and time-integrated ion energy distribution at the target are calculated by solving Poisson's equation coupled with fluid equations for collisionless ions and Boltzmann assumption for electrons using finite difference methods. The calculated results can further verify the feasibility and superiority of this new technique.
Mortality and Approximate Hazard Plots 1

Hazard rates are traditionally estimated using actuarial methods from mortality tables. Here we estimate hazard rates from tables of death frequencies for grouped ages using non-parametric methods and compare them with parametric methods. We use proportional hazard function to take into account lags in mortality and duration dependence of ailments that take effect in time.
A pole assignment controller for Bezier-Bernstein polynomial based Hammerstein model - Paper ID 95

In this paper pole assignment control is applied to the Hammerstein system of which the nonlinear static function is characterized by using the BezierBernstein approximation. In order to precompensate the nonlinearity in the closed loop system, the controller includes the inverse of the nonlinear static function which is represented as a Bezier curve with estimated knots. The computation of the inverse is based on the inverse of de Casteljau’s algorithm. In so doing the conventional linear pole assignment controller is applicable to the control of a Hammerstein system. An illustrative example is used to demonstrate the effectiveness of the algorithm.
