Performance of fennel varieties under organic production system

A field experiment was conducted to evaluate the fennel varieties tested for suitability under organic production system at ICAR-National Research Centre on Seed Spices, Ajmer, Rajasthan during the Rabi season 2015-16 to find out the varietal response under organic production system. Eight varieties viz., AF-1, RF-101, CO-01, GF-12, Rajendra Saurabh, RF-281, RF-125 and GF-02 were tested under the organic system. The results revealed that, the variety GF-12 and AF-1 performed better in organic production system compared to other tested varieties. The maximum plant height at harvest (222.40 cm), number of primary branches plant (11.53), number of secondary branches plant (22.40), number of umbels plant (45.73), number of umbelletes umbel (39.67) and highest seed yield (2365.80 kg ha) recorded in variety GF-12 followed by AF-1 (2354.10 kg ha). AF-1 variety recorded highest plant nutrient status as compared to other varieties. Among eight varieties of fennel GF-12 and AF-1 were found better for organic production system in terms of growth and seed yield.
Node‐to‐node consensus of multi‐agent networks with event‐triggered control and packet losses

This paper studies the node‐to‐node consensus problem for multi‐agent networks possessing a leaders' layer and a followers' layer via the pinning control. In order to realize the consensus and reduce the update frequency of the controller, a suitable event‐triggered mechanism is introduced into the control strategy. Furthermore, the phenomenon of packet loss is considered in the designed controller. Based on the M‐matrix theory and Lyapunov stability theory, this paper presents the sufficient conditions for the node‐to‐node consensus of networks. Meanwhile, it is proved that the Zeno behaviour is excluded. Finally, two numerical simulations are provided to demonstrate the effectiveness of the theoretical results.
Different Categories of Quantum Fields

Properties of a quantum field that represents an elementary particle and a quantum field that mediates an interaction between particles are analyzed. This analysis relies on fundamental physical principles. The mathematical structure of these fields proves that they are completely different physical objects. A further analysis proves that a quantum field that represents an elementary massive particle and a quantum field that represents a massless particle have a completely different mathematical structure. The results are used in an examination of free spin-1/2 elementary massive particles and other free elementary particles that have an integral spin. Inherent inconsistencies are found for elementary massive particles that have an integral spin and for the Majorana neutrino. The analysis also proves that interaction mediating fields do not represent a genuine particle.
Differential Reinforcement of Other Behavior: Effects of the Response-Reinforcement Interval

Forty male rats acquired a lever press response over eight sessions on a fixed interval (FI) schedule of reinforcement. After this acquisition phase subjects were randomly assigned to one of four treatment groups involving response elimination. Three of the groups received varying response-reinforcement intervals of 2, 6 and 18 seconds within a differential reinforcement of other behavior (DRO) paradigm. A reinforcement-reinforcement interval of 10 seconds was used for these animals. A control group receiving a standard extinction (EXT) contingency was also run for this 10 session treatment phase. One 15 minute reaquisition session followed the treatment sessions during which all animals were retrained on a FI 10 s schedule. During the treatment phase significant differences for the four groups were found after the first session. The DRO 2 group responded the most throughout the rest of this phase, followed by the EXT group, the DRO 6 group and finally the DRO 18 group. Significant results from the reacquisition phase were found only between minute two and five. At these times the DRO 2 group did not differ from the EXT group, but these two both were faster to reacquire the original response than both the DRO 6 and the DRO 18 group which had the slowest reacquisition. The results indicated that the longer the response-reinforcement interval the more effective the response elimination during treatment. Also,
Non-Linear Wave-Body Interaction in Severe Waves

Offshore structures located in harsh environments may experience large wave loads and wave-induced responses. The present thesis documents a twodimensional numerical investigation of interactions between fixed or floating structures and waves. Examined scenarios include large rigid-body motions and steep waves. The main objective of the research has been to develop an accurate and efficient fully non-linear potential-flow method for an incompressible liquid, and to use this in a systematic analysis to provide fundamental insight into wavebody interaction mechanisms beyond the capability of linear and weakly nonlinear methods. Free-surface tension is neglected. The numerical method uses the harmonic polynomial cell (HPC) method to solve the governing Laplace equation for the velocity potential and its time derivative. The HPC method is a field method where the entire fluid domain is discretized by overlapping cells, and the velocity potential in each cell is represented by harmonic polynomials up to fourth order. Here, the HPC method is proposed combined with novel features that include an immersed boundary method where markers track the time-evolution of the free surface, and using overlapping grids in a domain-decomposition strategy. By doing this, boundaries with arbitrary geometries are managed straightforwardly, and the numerical discretization can be refined locally without increasing the computational cost unnecessarily. Systematic studies are performed to validate the numerical method. It is shown that the solver is able to accurately propagate steep waves in deep and intermediate waters over a long time scale, and to deal with non-linear wave phenomena in shallow water including non-linear dispersion, solitary waves and a steep and eventually breaking focused wave. The method’s ability to deal with local free-surface behavior close to a curved body is confirmed through studying a circular cylinder undergoing forced heave motions in still water. Wave loads on a fixed ship section in beam-sea incident waves show satisfactory agreement with published reference results. A freely floating ship-section is studied in beam-sea waves with different wave heights. Wave-frequency motions and the mean wave drift force in sway are compared with experimental, numerical and theoretical reference results. Near heave and roll resonance, significant non-linear coupling effects are observed between the different modes of motion. In this wave-frequency range, mean wave drift forces larger than those predicted by second-order theory are observed. For higher wave frequencies, on the other hand, they are lower than from second-order theory. The latter is confirmed also when the body is restrained from moving. These
Invariant-based optimal composite stimulated Raman exact passage

Shortcuts to adiabaticity have been put forward for accelerating slow adiabatic passages in various quantum systems with tremendous applications for performing quantum information processing tasks. In this paper, we propose a hybrid protocol to achieve stimulated Raman exact passage (STIREP) by combining invariant-based inverse engineering, optimal control, and composite pulse approaches. We first derive the general solution and the corresponding pulse shapes by invariant-based inverse engineering. Counterintuitive and optimal (intuitive) pulse sequences are formulated in this context and incorporated into composite sequences. Such composite STIREP not only features robustness against the fluctuation of laser intensity, but also reduces the operation time and energy cost.

Rigid body stabilization under time-varying perturbations with zero mean values

The problem of monoaxial attitude control of a rigid body subjected to nonstationary perturbations is investigated. The control torque consists of a dissipative component and a restoring one. The cases of linear and nonlinear restoring and perturbing torques are analyzed. Two theorems on asymptotic stability of the programmed orientation are proved. The results of a numerical simulation are presented to confirm the conclusions obtained analytically.

A New Extension of the τ-Gauss Hypergeometric Function and Its Associated Properties

In this article, we define an extended version of the Pochhammer symbol and then introduce the corresponding extension of the τ-Gauss hypergeometric function. The basic properties of the extended τ-Gauss hypergeometric function, including integral and derivative formulas involving the Mellin transform and the operators of fractional calculus, are derived. We also consider some new and known results as consequences of our proposed extension of the τ-Gauss hypergeometric function.
The $\nu$-Tamari lattice via $\nu$-trees, $\nu$-bracket vectors, and subword complexes

We give new interpretations of the $\nu$-Tamari lattice of Pr\'eville-Ratelle and Viennot. First, we describe it as a rotation lattice of $\nu$-trees, which uncovers the relation with known combinatorial objects such as tree-like tableaux and north-east fillings. Then, using a formulation in terms of bracket vectors of $\nu$-trees and componentwise order, we provide a simple description of the lattice property. We also show that the $\nu$-Tamari lattice is isomorphic to the increasing-flip poset of a suitably chosen subword complex, and settle a special case of Rubey's lattice conjecture concerning the poset of pipe dreams defined by chute moves. Finally, this point of view generalizes to multi $\nu$-Tamari complexes, and gives (conjectural) insight on their geometric realizability via polytopal subdivisions of multiassociahedra.

Improving the Epoch of Reionization Power Spectrum Results from Murchison Widefield Array Season 1 Observations

Measurements of 21 cm Epoch of Reionization (EoR) structure are subject to systematics originating from both the analysis and the observation conditions. Using 2013 data from the Murchison Widefield Array (MWA), we show the importance of mitigating both sources of contamination. A direct comparison between results from Beardsley et al. and our updated analysis demonstrates new precision techniques, lowering analysis systematics by a factor of 2.8 in power. We then further lower systematics by excising observations contaminated by ultra-faint RFI, reducing by an additional factor of 3.8 in power for the zenith pointing. With this enhanced analysis precision and newly developed RFI mitigation, we calculate a noise-dominated upper limit on the EoR structure of Δ2 ≤ 3.9 × 103 mK2 at k = 0.20 h Mpc−1 and z = 7 using 21 hr of data, improving previous MWA limits by almost an order of magnitude.
Triggering of twists in solar prominence threads

Context. Magnetic twists are commonly associated with solar prominences. Twists are believed to play an important role in supporting the dense plasma against gravity as well as in prominence eruptions and coronal mass ejections, which may have a severe impact on the Earth and its near environment. Aims. We used a simple model to mimic the formation of a prominence thread by plasma condensation with the aim of investigating the possibility of triggering twists during this process. Methods. Temporal and spatial evolution of torsional Alfvénic perturbations driven by random photospheric motions was analysed using the linearised governing equations of motion and induction. Results. We find that small amplitude perturbations are exponentially amplified in time as they propagate along the condensing thread. Mechanisms contributing to the rapid growth are explored. The result of the amplification process is the generation of large amplitude axisymmetric twists along the thread. Conclusions. Magnetic twists may be triggered along a prominence thread when it is permeated by a converging flow, for example, during the evaporation and condensation of plasma along the thread. This may lead to the generation of vortices in the non-linear regime.
Stability analysis of systems with time‐varying delay: a quadratic‐partitioning method

During the course of analysing the stability of systems with time-varying delay, stability criteria are often shown in the form of the first- or second-order polynomial functions with respect to the time-varying delay. Therefore, the convex/concave property plays an important role in reducing the conservatism of stability criteria. In this note, the quadratic-partitioning method is proposed to take full advantage of the convex/concave property of a quadratic function, which can further reduce the conservatism of some of existing results. Two well-known numerical examples are given to illustrate the effectiveness of the proposed method.

Extended granular micromechanics approach: a micromorphic theory of degree n

For many problems in science and engineering, it is necessary to describe the collective behavior of a very large number of grains. Complexity inherent in granular materials, whether due the variability of grain interactions or grain-scale morphological factors, requires modeling approaches that are both representative and tractable. In these cases, continuum modeling remains the most feasible approach; however, for such models to be representative, they must properly account for the granular nature of the material. The granular micromechanics approach has been shown to offer a way forward for linking the grain-scale behavior to the collective behavior of millions and billions of grains while keeping within the continuum framework. In this paper, an extended granular micromechanics approach is developed that leads to a micromorphic theory of degree n. This extended form aims at capturing the detailed grain-scale kinematics in disordered (mechanically or morphologically) granular media. To this end, additional continuum kinematic measures are introduced and related to the grain-pair relative motions. The need for enriched descriptions is justified through experimental measurements as well as results from simulations using discrete models. Stresses conjugate to the kinematic measures are then defined and related, through equivalence of deformation energy density, to forces conjugate to the measures of grain-pair relative motions. The kinetic energy density description for a continuum material point is also correspondingly enriched, and a variational approach is used to derive the governing equations of motion. By specifying a particular choice for degree n, abridged models of degrees 2 and 1 are derived, which are shown to further simplify to micro-polar or Cosserat-type and second-gradient models of granular materials.

Tropospheric jet variability in different flow regimes

A transition in the variability properties of the jet stream is studied using a two‐layer quasi‐geostrophic model. The eddy energy is increased by controlling two parameters that affect baroclinic instability, causing the jet to shift poleward and leading to a stronger and less persistent annular mode. The transition in the jet variability properties as the eddy energy increases is associated with a transition from a merged (subtropical and eddy‐driven) jet regime to an eddy‐driven jet regime, and is accompanied by a transition in the eddy spectral properties. In the merged jet regime the spectrum is dominated by a single synoptic‐scale wave mode, whereas in the eddy‐driven jet regime the spectrum includes a wider range of planetary‐ and synoptic‐scale waves. An eddy–mean flow feedback mechanism explains the relation between the transition in the eddy spectrum and the jet variability properties. In the merged jet regime synoptic‐scale waves maintain the jet close to its climatological position at all times and act as a positive feedback on the weak annular mode, increasing its persistence. In the eddy‐driven jet regime the jet fluctuates between an equatorward‐shifted state, which is similar to the merged jet, and a poleward‐shifted state, where the eddy‐driven jet is separated from the subtropical jet. The low persistence of the annular mode in the eddy‐driven jet regime is due to a negative feedback by planetary‐scale waves, which grow barotropically on the poleward flank of the jet during the equatorward‐shifted jet state. The results of this study highlight the need to capture the dynamics of planetary‐scale waves correctly in general circulation models in order to prevent the emergence of an overly persistent annular mode.
