Suppletion or illusion?
Authors: Nichols Johanna 
Published: May 2019

Abstract
Constructing a typology and cross-linguistic survey for Aktionsart, actionality, and related notions is largely infeasible at present because so few Aktionsart systems have been fully described, they are typically complex and intricately dependent on verbal semantics and classification, and despite the inherent connection to the lexicon information about Aktionsart categories is rarely recoverable from dictionaries. As a first step this paper proposes a very minimal distinction of continuous (lacking inherent endpoints, chiefly states and activities) vs. bounded (having one or more endpoints, e.g. punctual, telic, and ingressive predicates and subtypes such as accomplishments and achievements). The word family of a predicate like sit can be based on the continuous form (as in English, where continuous sit is the base and sit down is derived) or on the bounded form (e.g. Slavic *sed- ‘sit down’ and derivative *sid-e-). A stumbling block in this endeavor has been sets like continuous know: bounded find out realize, etc. where no regular derivation relates the forms. Are they a paradigm? If so, what is the base? Structuralist criteria and Andersen's notion of markedness agreement indicate that they do form a paradigm and the continuous form is the base.
Changing attitudes to female genital mutilation: an integrative research review of recent literature on FGM in Nigeria.
Authors: Owojuyigbe M. A. 
Published: May 2019

Abstract
In Nigeria, 19.9 million girls and women aged between 15 and 49 years underwent female genital mutilation (FGM) between 2004 and 2015, making it a red-flag nation in terms of the practice. The paper notes the issues of bodily, medical, sexual and psychological harm and disability associated with the practice of FGM, and reviews societal attitudes to the practice of the subject in Nigeria as portrayed by the literature, especially in light of recent intervention efforts by different tiers of government, and non-governmental organizations, employing an integrative research review of 14 published articles on the subject, and concludes that changes in attitude to the practice in Nigeria have not been as significant as statistics suggest.
Gender and nutrition security.
Authors: Niehof A. 
Published: May 2019

Abstract
Many studies on nutrition that include gender do not take it further than observing male-female differences. In this review, I use the concept in the sociological sense and I conceptualize nutrition as embedded in household food security and pertaining to (gendered) performances that require resources. Using both quantitative data on associations and trends as well as qualitative findings that reveal mechanisms and subjectivities, I structure the discussion along three subject clusters of gender-nutrition interfaces, i.e. 'women's nutrition and gender inequalities'; 'food care'; and 'sons and daughters'. Regarding the first cluster, I found that because of women's hegemonic role in family food care and their often being relationally defined as mothers, their own nutritional needs tend to be considered instrumentally rather than as a matter in its own right. Gender inequalities affect women's nutrition through unfavourable intra-household food distribution patterns and poor access to crucial resources such as safe water and health care. They have an impact on women's care-giving abilities, and cause unequal treatment of sons and daughter. There is ample evidence that gender inequalities can propel an intergenerational cycle of female undernutrition. Because of the inequalities' entrenchment in daily life and in institutional frameworks, there are no easy solutions. However, female education (typically referred to as 'maternal' education) has been proven to alleviate the undernutrition of women and children. Finally, I conclude that gender inequality is a neglected aspect in defining sustainable nutrition and the relationship between women's nutrition and their reproductive rights a missing topic in the literature.
Regional management and biodiversity conservation in GIAHS: text analysis of municipal strategy and tourism management
Authors: Kohsaka Ryo , Matsuoka Hikaru , Uchiyama Yuta , Rogel Marie 
Published: May 2019

ABSTRACT

Purpose of the research:
To identify the gaps between the rhetoric and reality of the role of citizen participation and its role in maintenance and monitoring of heritages and resources (including biodiversity monitoring), we analyzed the discourse of Globally Important Agricultural Heritage System (GIAHS) at municipality level.

Methods:
As an analytical framework, text mining is applied to interviews of officers at the municipal level of GIAHS in Noto which was amongst the first sites in Japan. The identification of such gap is critical for sustainability and to prevent conflicts from tourism, agriculture or educations.

Results:
The results reveal that (1) there is a gap between the official goals of that designation at the international level and local needs, (2) role of citizens is emphasized in the applications and action plans at rhetorical level but remain rather limited in practice and that (3) municipalities composing the GIAHS often have different priorities, even within the very same GIAHS sites, some municipalities even calling themselves “just a transition point to other destination municipalities.”

Conclusions:
It is critical for municipal oﬃcers to collaborate with various stakeholders, especially citizens. As such, citizen science is a bottom-up approach to promote biodiversity conservation and facilitate GIAHS managements.
Extended Phase Space in the Framework of Holography*
Authors: Sherkatghanad Z. , Mirza B. , Nadi H. , Rostami M. 
Published: May 2019

Abstract

We consider a holographic extended phase space in the presence of Reissner-Nordstrom-Anti-de Sitter (RN-AdS) and Born-Infeld-Anti-de Sitter (BI-AdS) black holes in the bulk. In this extended phase space the cosmological constant is investigated as pressure and volume is defined as the codimension one-time slice in the bulk geometry enclosed by the minimal area appearing in the computation of the holographic entanglement entropy. These thermodynamics quantities can serve as probes of the underlying phase transition dictated by black hole thermodynamics, but do not describe different structures. We find that the isocharges on the pressure-volume plane exhibit a Van der Waals-like structure, for RN-AdS black holes in the background. For BI-AdS black holes, we observe the analogy with a Van der Waals liquid-gas system for βQ > 1/2 and Reentrant phase transition for βQ < 1/2 in the holographic extended phase space. The same holographic thermodynamic behavior is observed when we use the fidelity susceptibility as the volume and the cosmological constant as the pressure for RN-AdS black hole in the background.
Behavior of Anisotropic Compact Stars in f(R, ϕ) Gravity*
Authors: Shamir M. Farasat , Malik Adnan 
Published: May 2019

Abstract

The aim of this paper is to investigate modified f(R, ϕ) theory of gravity, where R and ϕ represent the Ricci scalar and scalar potential respectively. Specifically, we take the spherically symmetric spacetime to discuss the possible emergence of compact stars. We study the physical behavior of compact stars by considering 4U 1820-30, SAX J 1808-3658 and Her X1, which are three popular models of compact stars. The graphical analysis of energy density, radial pressure, tangential pressure, energy conditions as well as stability of compact stars has been shown. It is concluded that behavior of these three stars is usual for f(R, ϕ) gravity models with some specific choices of model parameters.
Phase Time for the Tunneling of Ultracold V-Type Atoms Through a Mazer Cavity*
Authors: Badshah Fazal , Basit Abdul , Ali Hamad , He Qing , Ge Guo-Qin 
Published: May 2019

Abstract

We study the tunneling time of ultracold V-type atoms interacting a high quality microwave cavity. Here atomic coherence is introduced in the system by a strong driving field which couples the two lower states of the three-level atom. It is found that in the presence of coherence, mazer action or the scattering like nature of the interaction may be examined for extended energies of the incident cold atoms. Our results show that position and amplitudes of the peak values of the phase time (traversal time) may be very effectively controlled by the coherent driving field. Further, here we obtained superclassical values of the phase time corresponding to much higher values of the transmission amplitudes of the tunneling atoms which may be advantageous in the possible experimental realization of the superclassical tunneling time of the traversing cold atoms. In addition, we examine a mirror reflection type symmetry in the phase time curve for a judicious choice of the external driving field.
Exact Solutions to the Quantum Rabi-Stark Model Within Tunable Coherent States*
Authors: Xie You-Fei , Chen Qing-Hu 
Published: May 2019

Abstract

The quantum Rabi-Stark model, where the linear dipole coupling and the nonlinear Stark-like coupling is present on an equal footing, is studied within the tunable extended coherent states. The eigenvalues and eigenstates are therefore obtained exactly. Surprisingly, the entanglement entropy in the ground-state is found to jump suddenly with the coupling strength. The first-order quantum phase transition can be detected by level crossing of the ground state and the first excited state, which is however lacking in the original linear quantum Rabi model. Performing the first-order approximation in the present theory, we can derive closed-form analytical results for the ground-state. Interestingly, it agrees well with the exact solutions up to the ultra-strong coupling regime in a wide range of model parameters. The spectral collapses when the absolute value of the nonlinear coupling strength approaches to twice the cavity frequency is observed with the help of new solutions in the limits.
Nonlinear saturation and oscillations of collisionless zonal flows
Authors: Zhu Hongxuan , Zhou Yao , Dodin I Y 
Published: May 2019

Abstract
In homogeneous drift-wave turbulence, zonal flows (ZFs) can be generated via a modulational instability (MI) that either saturates monotonically or leads to oscillations of the ZF energy at the nonlinear stage. This dynamics is often attributed as the predator–prey oscillations induced by ZF collisional damping; however, similar dynamics is also observed in collisionless ZFs, in which case a different mechanism must be involved. Here, we propose a semi-analytic theory that explains the transition between the oscillations and saturation of collisionless ZFs within the quasilinear Hasegawa–Mima model. By analyzing phase-space trajectories of DW quanta (driftons) within the geometrical-optics (GO) approximation, we argue that the parameter that controls this transition is N ∼ γ
MI/ω
DW, where γ
MI is the MI growth rate and ω
DW is the linear DW frequency. We argue that at N ≪ 1, ZFs oscillate due to the presence of so-called passing drifton trajectories, and we derive an approximate formula for the ZF amplitude as a function of time in this regime. We also show that at N ≳ 1, the passing trajectories vanish and ZFs saturate monotonically, which can be attributed to phase mixing of higher-order sidebands. A modification of N that accounts for effects beyond the GO limit is also proposed. These analytic results are tested against both quasilinear and fully-nonlinear simulations. They also explain the earlier numerical results by Connaughton et al (2010 J. Fluid Mech.
654 207) and Gallagher et al (2012 Phys. Plasmas
19 122115) and offer a different perspective on what the control parameter actually is that determines the transition from the oscillations to saturation of collisionless ZFs.
Second order conformal multi-symplectic method for the damped Korteweg–de Vries equation*
Authors: Guo Feng 
Published: May 2019

Abstract
A conformal multi-symplectic method has been proposed for the damped Korteweg–de Vries (DKdV) equation, which is based on the conformal multi-symplectic structure. By using the Strang-splitting method and the Preissmann box scheme, we obtain a conformal multi-symplectic scheme for multi-symplectic partial differential equations (PDEs) with added dissipation. Applying it to the DKdV equation, we construct a conformal multi-symplectic algorithm for it, which is of second order accuracy in time. Numerical experiments demonstrate that the proposed method not only preserves the dissipation rate of mass exactly with periodic boundary conditions, but also has excellent long-time numerical behavior.
Turing pattern in the fractional Gierer–Meinhardt model*
Authors: Wang Yu , Zhang Rongpei , Wang Zhen , Han Zijian 
Published: May 2019

Abstract
It is well-known that reaction–diffusion systems are used to describe the pattern formation models. In this paper, we will investigate the pattern formation generated by the fractional reaction–diffusion systems. We first explore the mathematical mechanism of the pattern by applying the linear stability analysis for the fractional Gierer–Meinhardt system. Then, an efficient high-precision numerical scheme is used in the numerical simulation. The proposed method is based on an exponential time differencing Runge–Kutta method in temporal direction and a Fourier spectral method in spatial direction. This method has the advantages of high precision, better stability, and less storage. Numerical simulations show that the system control parameters and fractional order exponent have decisive influence on the generation of patterns. Our numerical results verify our theoretical results.
Tensile-strain induced phonon splitting in diamond*

Published: May 2019

Abstract
The first-order Raman spectroscopy of diamond exhibits splitting and redshift after the burst of high-pressure (160–200 GPa) and high-temperature (∼2000 K). The observed longitudinal optical (LO) and the transverse optical (TO) splitting of Raman phonon is related to the tensile-strain induced activation of the forbidden or silent Raman modes that arise in the proximity of the Brillouin zone center.

Dynamics of Airy beams in parity–time symmetric optical lattices
Authors: Chen Rui-Hong , Hong Wei-Yi 
Published: May 2019

Abstract
We investigate the dynamics of airy beams propagating in the parity–time (PT) symmetric optical lattices in linear and nonlinear regimes, respectively. For the linear propagation, the position of the channel guided by the PT lattice can be shifted by tuning the lattice frequency. The underlying physical mechanism of this phenomenon is also discussed. An interesting phenomenon is found in the nonlinear regime in that the airy beam becomes a tilt channel with several Rayleigh lengths. These findings create new opportunities for optical steering and manipulations.
Mid-infrared supercontinuum generation and its application on all-optical quantization with different input pulses*
Authors: Li Yan , Sang Xinzhu 
Published: May 2019

Abstract
Supercontinuum generation (SCG) and its application on all-optical quantization of all-optical analog-to-digital conversions (AOADCs) at the mid-infrared region in an AlGaAs strip waveguide are investigated numerically. The simulation results show that when the parabolic pulse is input, not only broader and higher-coherence SCG is obtained and a higher effective number of bits (ENOB) can be achieved, compared with the input pulse with hyperbolic-secant and Gaussian shaping. A four-bit quantization resolution is achieved along with a signal-to-noise ratio of 24.02 dB and an ENOB of 3.99 bit, and the required input peak power is 760 mW.
An experimental method for quantitative analysis of real contact area based on the total reflection optical principle*
Authors: Luo Zhijun , Song Baojiang , Han Jingyu , Yan Shaoze 
Published: May 2019

Abstract
The simulation of real contact area between materials is foundationally important for the contact mechanics of mechanical structures. The Greenwood and Williamson (GW) model and the Majumdar (MB) model are the basic models in this field, which are widely accepted and proven to be valid in many experiments and engineering. Although the contact models have evolved considerably in recent years, the verifications of the models are most based on the indirect methods such as electrical conductivity and contact stiffness, because of the lack of effective methods to directly measure the variation of contact surface. In this paper, the total reflection (TR) method is introduced into the verification of contact models. An experiment system based on TR method is constructed to measure the real contact area of two PMMA specimens. The comparison analysis between the results of experiment and models suggests that the experiment result has the same trend with simulation, the MB model has better agreement with the experimental result because this method can take into account the variation of radius and the merging of asperities, while the GW model has a huge deviation because of the dependence on resolution and the lack of considering the variation of radius and asperity’s merging process. Taking the interaction of asperities into account could give a better result that is closer to the experiment. Our results and analysis prove that the experimental methods in this paper could be used as a more direct and valid method to quantitatively measure the real contact area and to verify the contact models.

Published: May 2019

Abstract
We report a comprehensive Raman scattering study on layered MPS3 (M=Mn, Fe, Ni), a two-dimensional magnetic compound with weak van der Waals interlayer coupling. The observed Raman phonon modes have been well assigned by the combination of first-principles calculations and the polarization-resolved spectra. Careful symmetry analysis on the angle-dependent spectra demonstrates that the crystal symmetry is strictly described by C2h but can be simplified to D3d with good accuracy. Interestingly, the three compounds share exactly the same lattice structure but show distinct magnetic structures. This provides us with a unique opportunity to study the effect of different magnetic orders on lattice dynamics in MPS3. Our results reveal that the in-plane Néel antiferromagnetic (AF) order in MnPS3 favors a spin–phonon coupling compared to the in-plane zig-zag AF in NiPS3 and FePS3. We have discussed the mechanism in terms of the folding of magnetic Brillouin zones. Our results provide insights into the relation between lattice dynamics and magnetism in the layered MPX
3 (M=transition metal, X=S, Se) family and shed light on the magnetism of monolayer MPX

Conductive property of Zr0.1Fe0.9V1.1Mo0.9O7 with low thermal expansion*
Authors: He Xiaoke , Qi Heng , Xu Qi , Liu Xiansheng , Xu Lei , Yuan Baohe 
Published: May 2019

Abstract
Low thermal expansion materials are mostly ceramics with low conductive property, which limits their applications in electronic devices. The poor conductive property of ceramic ZrV2O7 could be improved by bi-substitution of Fe and Mo for Zr and V, accompanied with low thermal expansion. Zr0.1Fe0.9V1.1Mo0.9O7 has electrical conductivity of 8.2×10−5 S/cm and 9.41×10−4 S/cm at 291 K and 623 K, respectively. From 291 K to 413 K, thermal excitation leads to the increase of carrier concentration, which causes the rapid decrease of resistance. At 413–533 K, the conductivity is unchanged due to high scattering probability and a slowing increase of carrier concentration. The conductivity rapidly increases again from 533 K to 623 K due to the intrinsic thermal excitation. The thermal expansion coefficient of Zr0.1Fe0.9V1.1Mo0.9O7 is as low as 0.72×10−6 K−1 at 140–700 K from the dilatometer measurement. These properties suggest that Zr0.1Fe0.9V1.1Mo0.9O7 has attractive application in electronic components.
Mott transition in ruby lattice Hubbard model*
Authors: Bao An 
Published: May 2019

Abstract
Mott transition in a ruby lattice with fermions described by the Hubbard model including on-site repulsive interaction is investigated by combining the cellular dynamical mean-field theory and the continuous-time quantum Monte Carlo algorithm. The effect of temperature and on-site repulsive interaction on the metallic–insulating phase transition in ruby lattice with fermions is discussed based on the density of states and double occupancy. In addition, the magnetic property of each phase is discussed by defining certain magnetic order parameters. Our results show that the antiferromagnetic metal is found at the low temperature and weak interaction region and the antiferromagnetic insulating phase is found at the low temperature and strong interaction region. The paramagnetic metal appears in whole on-site repulsive interaction region when the temperature is higher than a certain value and the paramagnetic insulator appears at the middle scale of temperature and on-site repulsive interaction.
