Authors: Wang Jingyi , Mao Xinguo , Wang Ruitong , Li Ang , Zhao Guangyao , Zhao Jinfeng , Jing Ruilian
Published: January 2019

Abiotic stress significantly impacts growth and yield of crop plants. It is imperative for crop improvement to discover and utilize stress-tolerant functional genes. In this study, genes responding to abiotic stresses, such as freezing, salt and osmotic stress, were screened from a cDNA yeast library that was constructed from the drought- and heat-tolerant wheat variety Hanxuan 10. After screening for surviving clones we isolated 7,249, 4,313 and 4,469 raw sequences, corresponding to 4,695, 2,641 and 2,771 genes following each treatment. Venn diagrams revealed 377 overlapping genes. GO analysis suggested that these genes were mainly involved in the metabolic and stress signal pathways. KEGG pathway enrichment analysis indicated that the isolated genes predominantly belonged to pathways concerning energy and metabolism. Overlapping gene TaPR-1-1 within the pathogenesis-related (PR) protein family was selected for detailed characterization. Although previous studies had shown that PR genes function during pathogen attack, our results demonstrated that TaPR-1-1 expression was also induced by freezing, salinity, and osmotic stresses. Overexpression in yeast and Arabidopsis showed that TaPR-1-1 conferred tolerance to these stresses. We concluded that screening cDNA yeast libraries following abiotic stress is an efficient way to identify stress-tolerance genes.

History and future of shotgun glycomics
Authors: Smith David F. , Cummings Richard D. , Song Xuezheng
Published: January 2019

Glycans in polysaccharides and glycoconjugates of the hydrophilic exterior of all animal cells participate in signal transduction, cellular adhesion, intercellular signaling, and sites for binding of pathogens largely through protein–glycan interactions. Microarrays of defined glycans have been used to study the binding specificities of biologically relevant glycan-binding proteins (GBP), but such arrays are limited by their lack of diversity or relevance to the GBP being investigated. Shotgun glycan microarrays are made up of structurally undefined glycans that were released from natural sources, labeled with bifunctional reagents so that they can be monitored during their purification using multidimensional chromatographic procedures, stored as a tagged glycan library (TGL) and subsequently printed onto microarrays at equal molar concentrations. The shotgun glycan microarray is then interrogated with a biologically relevant GBP and the corresponding glycan ligands can be retrieved from the TGL for detailed structural analysis and further functional analysis. Shotgun glycomics extended the defined glycan microarray to a discovery platform that supports functional glycomic analyses and may provide a useful process for ultimately defining the human glycome.

Published: January 2019

Coenzyme A (CoA) thioesters (acyl-CoAs) are essential intermediates of metabolism. Inborn errors of acyl-CoA metabolism include a large fraction of the classical organic acidemias. These conditions can involve liver, muscle, heart and brain, and can be fatal. These conditions are increasingly detected by newborn screening. There is a renewed interest in CoA metabolism and in developing effective new treatments. Here, we review theories of the pathophysiology in relation to mitochondrial CoA sequestration, toxicity and redistribution (CASTOR).
Lossy flat‐passband signal‐interference microstrip filter
Authors: Gómez‐García Roberto , Muñoz‐Ferreras José‐María , Yang Li , Feng Wenjie
Published: January 2019

A type of lossy transversal‐signal‐interference planar bandpass filter (BPF) with a flattened passband is reported in this Letter. The authors exploit in‐series‐cascaded transversal filtering sections composed of two in‐parallel transmission‐line segments and series‐type lossy hybrid resonators connected at their inputoutput accesses. The resistors of these lossy resonators by dissipating part of the RF‐input‐signal energy in the BPF passband region following a complementary frequency‐variation profile with regard to the one associated with conventional substrate filter loss allow obtaining an overall flattened transmission band. To experimentally validate the proposed approach, a 2 GHz microstrip prototype of a sharp‐rejection lossy signal‐interference BPF with a flattened passband is developed and characterised.

Published: January 2019

In this study, the authors consider the sensors' connection model design and energy optimisation of routing protocol in wireless sensor networks based on the Gaussian network connection model. Accordingly, by the node‐symmetric and four different directions to four adjacent nodes of each node in the Gaussian network model, the study recommends a new wireless sensor network connection model, on which the network area will be divided into some virtual square grids. In the new wireless sensor network connection model, they describe each virtual square grid as a node in the Gaussian network, therefrom, they propose a routing method, which is a combination of the shortest path routing protocol in the Gaussian network and clustering protocol to improve the routing efficiency of the wireless sensor network. Some simulations were implemented in NS2, the results show that the proposed routing is very good.
Model‐based control strategy for oversaturated traffic regimes based on the LWR‐IM traffic model
Authors: Ng Kok Mun , Reaz Mamun Bin Ibne , Mohd Ali Mohd Alauddin
Published: January 2019

Model‐based optimal control strategies were capable of handling saturated traffic regimes with the ability to maintain optimised network performance. However, the upstream queue spillback which was not considered by these strategies renders an inefficient handling of oversaturated traffic regime. Hence, oversaturated situations needs both traffic flow coordination and queue spillback regulation. Here, the author aims to regulate oversaturated regimes with model‐based control strategy (MCS) based on the Lighthill‐Whitham‐Richards–integrated model (LWR‐IM) traffic model. A traffic simulator which was developed in a previous work is further extended with the proposed MCS. The MCS comprised of a rolling horizon network prediction and control algorithms at both the network and intersection levels. Based on future predictions of platoon sizes, arrival times, and queues; phase durations are adjusted at the intersection level by employing a proportionate methodology in responding to the incoming platoons and a regulation strategy to handle queue spillback. The proposed MCS was tested on real‐world traffic via simulations to assess its performance compared to existing fixed‐time system. The MCS improved the average delays and network throughput significantly and manage to keep queues from spilling back upstream. In addition, the strategy is feasible for real‐time implementation.
Research on a coordinated cornering brake control of three‐axle heavy vehicles based on hardware‐in‐loop test
Authors: Li Shaohua , Zhao Junwu , Yang Shaopu , Fan Haoyang
Published: January 2019

A direct yaw moment controller/anti‐lock braking system (DYC/ABS) coordinated cornering brake control scheme is proposed for three‐axle vehicles to improve the handling performance while shortening the brake distance. A proportional–integral method is designed in DYC control. The cornering stiffness of the two‐degrees of freedom vehicle model is fitted in real time. The Dugoff tire model is used to establish the relationship between the yaw moment and wheel slip ratio; an optimal allocation method is proposed to allocate the force requirements to each tire. To verify the effect, vehicle responses under various speeds and turning radii are analysed with DYC/ABS coordinated control, ABS control, and no control based on co‐simulation of TruckSim and MATLAB/Simulink. According to the chattering caused by sliding mode control, two sliding mode controllers using saturation function and modified exponential reaching law are, respectively, designed to obtain the braking moment in ABS control. A pneumatic braking hardware‐in‐loop (HIL) test system is developed; the effectiveness of the strategy is verified by experiments. The results show that the coordinated control can reduce lateral acceleration, brake distance, and brake time when the vehicle runs under cornering brake; thus has an excellent effect on balancing the handling stability and braking safety.
Lyapunov model predictive control to optimise computational burden, reference tracking and THD of three‐phase four‐leg inverter
Authors: Dadu Abdul Mannan , Mekhilef Saad , Soon Tey Kok
Published: January 2019

Due to the evolution of high processing microprocessors, the model predictive control (MPC) has been widely used in power electronic applications. In spite of simplicity, flexibility and fast dynamic response, the conventional MPC (C‐MPC) has a drawback of computational burden. This study focuses on Lyapunov MPC (L‐MPC) method, in which Lyapunov control law is employed in the cost function to minimise the error between the desired control variables and the actual control variables of three‐phase four‐leg inverter to optimise the closed‐loop system performance. The proposed control algorithm takes advantage of a predefined Lyapunov control law which minimises the required calculation time by the Lyapunov model equations just once in each control loop to predict the future variables. L‐MPC technique improves the digital speed by 23.8% as compared to C‐MPC. It reduces current tracking error and total harmonic distortion (THD) in the variation of inverter control parameters. The stability of the system is established through Lyapunov function with the help of backsteping control method. The LabVIEW field programmable gate array (FPGA) rapid prototyping controller is used to validate the proposed control method. The experimental results showed that the proposed system has better performance as compared to C‐MPC.
Effects of wideband waveforms on simultaneous scattering matrix measurement of manoeuvring targets
Authors: Liu Qiao‐ling , Pang Chen , Li Yong‐zhen , Wang Xue‐song
Published: January 2019

Both polarimetry and Doppler characteristics can be employed in remote sensing applications. Doppler information provides insight into the dynamic properties of radar targets, and polarimetry is associated with the intrinsic attributes of targets. Determining how to obtain accurate polarisation measurements from Doppler information has been a concern. For high‐speed targets, the relativistic effect on radar wideband echoes may be notable. With the conventional matched filter, this scale effect may produce significant amplitude and phase errors between two columns of the polarisation scattering matrix (PSM), except for signal‐to‐noise ratio (SNR) loss. On the basis of the Taylor series expansion, the amplitude and phase expressions are derived in this study. Theoretical analysis shows that the amplitude and phase errors are related to the time–frequency allocation of the orthogonal waveforms and that the accuracy of the PSM is more susceptible to scale factors using frequency modulation waveforms than phase‐coded waveforms. To suppress these amplitude and phase errors, a compensation method is proposed for orthogonal linear frequency modulation signals. Furthermore, the performances of the SNR loss and the velocity error effect are given. Finally, some numerical experimental results are provided to illustrate the effectiveness of the compensation.
A 10-M⊙ YSO with a Keplerian disk and a nonthermal radio jet

Published: January 2019

Context. To constrain present star formation models, we need to simultaneously establish the dynamical and physical properties of disks and jets around young stars.

Aims. We previously observed the star-forming region G16.59−0.05 through interferometric observations of both thermal and maser lines, and identified a high-mass young stellar object (YSO) which is surrounded by an accretion disk and drives a nonthermal radio jet. Our goals are to establish the physical conditions of the environment hosting the high-mass YSO and to study the kinematics of the surrounding gas in detail.

Methods. We performed high-angular-resolution (beam FWHM ≈ 0′′.15) 1.2-mm continuum and line observations towards G16.59−0.05 with the Atacama Large Millimeter Array (ALMA).

Results. The main dust clump, with size ≈104 au, is resolved into four distinct, relatively compact (diameter ~2000 au) millimeter (mm) sources. The source harboring the high-mass YSO is the most prominent in molecular emission. By fitting the emission profiles of several unblended and optically thin transitions of CH3OCH3 and CH3OH, we derived gas temperatures inside the mm sources in the range 42–131 K, and calculated masses of 1–5 M⊙. A well-defined Local Standard of Rest (LSR) velocity (VLSR) gradient is detected in most of the high-density molecular tracers at the position of the high-mass YSO, pinpointed by compact 22-GHz free-free emission. This gradient is oriented along a direction forming a large (≈70°) angle with the radio jet, traced by elongated 13-GHz continuum emission. The butterfly-like shapes of the P–V plots and the linear pattern of the emission peaks of the molecular lines at high velocity confirm that this VLSR gradient is due to rotation of the gas in the disk surrounding the high-mass YSO. The disk radius is ≈500 au, and the VLSR distribution along the major axis of the disk is well reproduced by a Keplerian profile around a central mass of 10 ± 2 M⊙. The position of the YSO is offset by ≳0′′.1 from the axis of the radio jet and the dust emission peak. To explain this displacement we argue that the high-mass YSO could have moved from the center of the parental mm source owing to dynamical interaction with one or more companions.

Néel transition in the multiferroic BiFeO3-0.25PbTiO3 nanoparticles with anomalous size effect
Authors: Harijan Pappu Kumar , Singh Anar , Upadhyay Chandan , Pandey Dhananjai
Published: January 2019

The role of size reduction on the structural parameters, antiferromagnetic transition temperature (TN), and spin reorientation transition temperature of BiFeO3-0.25PbTiO3 (BF-0.25PT) has been studied. Rietveld analysis using high resolution synchrotron x-ray powder diffraction data confirms that the space group of BF-0.25PT solid solutions is monoclinic Cc and not rhombohedral R3c for both bulk and nanocrystalline powders. This settles a longstanding controversy about the structure of these solid solutions toward the BiFeO3 rich end of the morphotropic phase boundary in the BiFeO3-xPbTiO3 system. Using magnetization and neutron powder diffraction data, we show that the Néel transition temperature (TN) of BF-0.25PT increases from 445 K for bulk to 480 K for 150 nm particle size. This is in marked contrast to the scaling theories of phase transitions in finite size systems. We also show that the spin reorientation transition occurring below TN in bulk monoclinic compositions like BF-0.25PT is suppressed in the nanocrystalline samples of ∼150 nm particle size. Based on Rietveld refined structural parameters, we show that the asymmetry and non-linearity of the Fe-O-Fe superexchange pathways grow with decreasing particle size and that they exhibit a strong correlation with TN. We believe that the substantially enhanced Dzyaloshinskii-Moriya interaction with decreasing particle size as a result of asymmetric and non-collinear Fe-O-Fe superexchange pathways may be the key factor in raising the TN on decreasing the particle size. These observations present a new facet of type-I multiferroic materials, where superexchange pathways are intimately dependent on the ferroelectric distortion.
Giant enhancement of nonlinear absorption in graphene oxide—Sb2Se3 nanowire heterostructure
Authors: Yadav Rajesh Kumar , Aneesh J. , Sharma Rituraj , Salvi M. , Jayabalan J. , Jain H. , Adarsh K. V.
Published: January 2019

Nanosheet-nanowire heterostructure provides a new platform to explore the nonlinear optical phenomena at the nanoscale. In this article, we report giant nonlinear absorption (NLA) coefficient ≈0.94 × 103 cm/GW at 1064 nm and 0.64 × 103 cm/GW at 532 nm in a new type of heterostructure of two-dimensional graphene oxide (GO) nanosheets and one-dimensional Sb2Se3 nanowires prepared by a facile hydrothermal method. The giant enhancement of NLA by the heterostructure is attributed to synergistic charge transfer between the Sb2Se3 nanowire and GO nanosheet through the donor-acceptor interaction. With this idea, we have developed a five-level rate equation model and numerically simulated the results. Strikingly, the heterostructure shows an excellent benchmark for the optical limiting onset of 8 mJ/cm2 at 1064 nm and 20 mJ/cm2 at 532 nm, that is, an order of magnitude better than graphene based materials, 2D transition metal dichalcogenides, and metal nanoparticles over a broad spectral range.
Numerical simulation of lithium granule injection in tokamak edge plasma
Authors: Gao Fang , Sun Jizhong , Liu Lijun , Sun Zhen , Bonnin Xavier , Liu Jinyuan
Published: January 2019

To understand how a Li pellet affects the background plasma, the edge plasma code SOLPS combined with a neutral-gas-shield ablation model has been employed to simulate the transport of Li species in the edge plasma during Li pellet injections in a typical EAST H-mode plasma. The simulation results show that a Li pellet 0.5 mm with velocity ∼100 m/s can penetrate the separatrix, and that the electron temperature drops quickly where the pellet passes by while the electron density needs a longer time to respond. The plasma pressure in the pedestal region grows significantly with the pellet size; the pressure gradient changes even more drastically. This work indicates that without accumulative contributions, a pellet 0.7 mm or above in diameter at an injection velocity of 100 m/s is likely to provide a pressure perturbation enough to trigger ELMs in the typical EAST H-mode plasmas used in this work.

Published: January 2019

In this work, we fabricated a ZnO thin film flexible UV photodetector with a room-temperature process and investigated it with an emphasis on the influence of different external stresses. The photodetector exhibited enhancing photocurrent, sensitivity, responsivity, and response range with a tensile strain. This may originate from the improving collection ability of photogenerated carriers with the change of Schottky barrier height, which is induced by the piezo-phototronic effect. The as-obtained thin film flexible photodetector belongs to the family of photoresponse-controlled optoelectronic devices and has applications in a myriad of useful ways.
On cooling/heating mechanisms in a self-cooled light-emitting diode with type-II band offset
Authors: Ma Fa-Jun , Hameiri Ziv , Bagnall Darren , König Dirk , Puthen-Veettil Binesh
Published: January 2019

A p+-i-n+ self-cooled light-emitting diode with type-II band offset is numerically simulated in one-dimension to examine the underlying cooling/heating mechanisms. The Peltier effect is confirmed to be the dominant cooling mechanism under forward bias, even when the carriers are injected without an energy barrier. Meanwhile, Joule heating in the active layer is identified as the main heating mechanism for bandgaps below 0.52 eV under an ultra-low forward bias. In contrast to non-radiative recombination, electroluminescence itself is found to be a cooling mechanism, producing most photons above the bandgap of the active layer. However, this effect only becomes noticeable under an ultra-low bias in very small bandgap materials. While it is desirable to inject more carriers to leverage larger band offsets for a higher cooling power, Joule heating limits the maximum cooling power achievable. With small band offsets (<0.21 eV), a reverse bias instead of a forward bias may become the best cooling condition, where non-radiative generation processes are discovered to be the dominant cooling mechanisms.

In this work, ultra-thin hexagonal boron nitride (h-BN) flakes are employed as substrates for scanning transmission electron microscopy. The thicknesses of only a few atomic layers, the flat surface, and the large bandgap provide a unique set of properties, which makes h-BN ideally suitable for high resolution plasmon spectroscopy by means of electron energy loss spectroscopy (EELS), especially for small nanoparticles. A facile fabrication process allows the production of h-BN substrates with a thickness of only a few atomic layers. The advantages of h-BN, especially for the low-loss energy region of EEL spectra, are shown in a direct comparison with a silicon nitride substrate. Furthermore, results of the investigation of localized surface plasmon resonances (LSPRs) of Ag and Ag–Au core–shell nanoparticles in the sub-20 nm size regime are presented, confirming the advantages of the fabricated substrate for LSPR mapping. The plasmonic nanoparticles were assembled utilizing the helium nanodroplet synthesis approach, which allows for a very soft deposition and the preservation of the integrity of the ultra-thin substrate. Moreover, it provides a completely solvent and surfactant free environment for the assembly of tailored nanoparticles.
Linear and sublinear scaling computation of the electronic g-tensor at the density functional theory level

Published: January 2019

We present an efficient and low-scaling implementation of a density functional theory based method for the computation of electronic g-tensors. It allows for an accurate description of spin-orbit coupling effects by employing the spin-orbit mean-field operator. Gauge-origin independence is ensured by the use of gauge-including atomic orbitals. Asymptotically linear scaling with molecule size is achieved with an atomic orbital based formulation, integral screening methods, and sparse linear algebra. In addition, we introduce an ansatz that exploits the locality of the contributions to the g-tensor for molecules with local spin density. For such systems, sublinear scaling is obtained by restricting the magnetic field perturbation to the relevant subspaces of the full atomic orbital space; several criteria for selecting these subspaces are discussed and compared. It is shown that the computational cost of g-tensor calculations with the local approach can fall below the cost of the self-consistent field calculation for large molecules. The presented methods thus enable efficient, accurate, and gauge-origin independent computations of electronic g-tensors of large molecular systems.

Micromagnetic simulations studies on Permalloy (Ni80Fe20) nanodots with different shapes and edge-to-edge separations (s) down to 25nm arranged in square lattice are reported. We observe the significant variation of spin-wave (SW) dynamics of nanodots of different shapes (triangular, diamond and hexagon) and of fixed dot diameter 100nm with varying s. Modes for single dot are transformed in an array into multiple quantized, edge and centre modes for different shapes and edge-to-edge separations, with different spin wave frequencies and peak intensities. Specifically, in the triangular dot sample, a broad range of mode frequencies is observed with highest SW frequency 14.7 GHz. For separation less than 100nm, the SW frequencies undergoes significant modification due to the varying nature of the magnetostatic and dipolar interaction in the array while for separations above 100nm, the SW frequency mostly remain constant. The power profiles confirm the nature of the observed modes. The spatial profiles of magnetostatic field are determined by a combination of internal magnetic-field profiles within the nanodots and the magnetostatic fields within the lattice. The inter-dots interaction of magnetostatic field shows dipolar and quadrupole contributions for all the shapes. Interestingly, vortex states with shifted core and polarity are observed in the array for all the shapes at Hbias = 0. Our results provide important understanding about the tunability of SW spectra in the array of triangular, diamond and hexagon shaped nanoelements.

Published: January 2019

The Raman spectra of liquid H2(D2) have been collected in diamond anvil cell as a function of temperature at 3 GPa covering the range from 80 to ∼1000K. Temperatures were measured using two independent methods: by thermocouple and from the relative intensity ratio of the present Raman modes. We find excellent agreement between the two methods in the low temperature regime (80 to 400 K) but observe discrepancies between these approaches at temperatures above 400 K. We attribute that the temperature difference between the two methods arises primarily from the proximity of the thermocouple relative to the heating elements and sample. Although not always available in high-pressure experiments, the metrology based on in situ physical properties of the sample is absolute and more reliable than the secondary gauges based on external devices.

La-doped 0.15BiInO3-0.85PbTiO3 thin films are deposited on SRO/Pt/MgO substrates by RF-magnetron sputtering method. The structures of the thin films are characterized by XRD and AFM. Meanwhile, the effects of La doping concentrations on the piezoelectricity of the films are measured. At the same time, the transverse piezoelectric coefficients of the films are simulated by COMSOL combined with CASTEP calculations. The simulated results are in agreement with the experimental data, which show that the La-doping 0.15BiInO3-0.85PbTiO3 films have optimized properties by properly controlling the La doping compositions. It is found that the effective transverse piezoelectric coefficients have a maximum of -9.35 C/m2 as 3 mol.% La-doping 0.15BiInO3-0.85PbTiO3 films.
A geometrical criterion for absolute instability in separated boundary layers
Authors: Avanci Mateus P. , Rodríguez Daniel , Alves Leonardo S. de B.
Published: January 2019

Laminar separation bubbles on airfoils and low-pressure turbines are generally expected to be dominated by convective inflectional instability. However, absolute instability is possible under certain circumstances, which may lead to important changes in the laminar-turbulent transition, reattachment processes, and their impact on the aerodynamics. This paper revisits the absolute/convective instability properties of different families of boundary-layer velocity profiles with a reversed flow region. A new methodology is employed in the analysis, which incorporates an additional equation to the classic Rayleigh’s equation governing inviscid instability. This allows for the direct recovery of the zero-group-velocity disturbance waves that govern the absolute/convective behavior, at an unprecedented low computational cost that enabled the large parametric study performed here. Present results show that while the peak reversed flow or wall-normal extent of the reversed flow impact the instability character, criteria based on any of them are generally not valid. A new criterion is proposed, based on the relative position of the inflection point: inviscid inflectional instability becomes of an absolute kind when the inflection point is located inside of the recirculation region. Absolutely unstable velocity profiles are identified with peak reversed flow as low as 10% of the free-stream velocity, a value substantially smaller than thresholds previously proposed in the literature.

A high-Q magnetoelectric (ME) gyrator consisting of a trilayer laminate of nickel-iron-based constant elasticity alloy (Ni–Fe–Cr) and lead zirconate titanate with a coil wound around it has been developed and systematically characterized. Highly efficient magneto-mechanical-electric conversion can be achieved by means of the combination contributions of high quality factors from individuals, and much energy can be transferred through the gyration device. Under an electromechanical resonance frequency of 54.04 kHz, experimental results show that maximum efficiency reaches as high as 88.5% under an extremely low input density of 3.31 µW/cm3 with an optimum load resistance of 9.6 kΩ and a magnetic bias of 66 Oe. Such a highly efficient ME gyrator with a high Q factor can be beneficial or degrade the design goals that are likely to be achievable for practical applications in compact power transfer electronic devices.
'Right fit, right job, right time': case study of a new model for allied health recruitment in public health settings
Authors: Withiel Toni , Marr Lucinda , Juj Genevieve
Published: January 2019

Objective
Staff turnover remains a significant financial burden across the healthcare sector. Traditional approaches to recruitment continue to prioritise competency-based outcomes over the cultural fit of applicants. This brief case study sought to evaluate the effectiveness of a new recruitment intervention on allied health staff attrition rates at the Royal Melbourne Hospital, Australia.

Methods
The study used a single-site, prospective, mixed-methodology research design. Staff attrition rate, defined as the number of staff who ceased employment within 12 months of starting (both voluntarily and involuntarily), was selected as the primary outcome measure. Baseline data were collected in the 12 months before intervention roll out. Data were supplemented by surveying staff on interview panels and by feedback from consumer interview panel members.

Results
Descriptive analysis revealed that there was a decrease in the overall staff attrition rates following the introduction of the new recruitment model. Survey data revealed that interviewers rated the new recruitment strategy as more effective than traditional approaches. Several unique benefits associated with the inclusion of consumer advocates were also identified.

Conclusion
A behaviourally grounded recruitment approach to allied health improves overall staff attrition over traditional competency-based models.
The electrical signal-induced systemic photosynthetic response is accompanied by changes in the photochemical reflectance index in pea

Plants can be affected by numerous environmental stressors with spatially heterogeneous actions on their bodies. A fast systemic photosynthetic response, which is connected with long-distance electrical signalling, plays an important role in the adaptation of higher plants to the action of stressors. Potentially, measurement of the response by using a photochemical reflectance index (PRI) could be the basis of monitoring photosynthesis under spatially heterogeneous stressors; however, the method has not been previously used for investigating the systemic photosynthetic response. We investigated changes in PRI and photosynthetic parameters (quantum yields of PSI and PSII and nonphotochemical quenching) in intact leaves of pea (Pisum sativum L.) after local heating of another leaf and the propagation of electrical signals through the plant body. We showed that electrical signals decreased the quantum yields of PSI and PSII and increased the nonphotochemical quenching of intact leaves in times ranging from minutes to tens of minutes; the changes were strongly connected with changes in PRI. Additional analysis showed that changes in PRI were caused by an increase of the energy-dependent quenching induced by electrical signals. Thus PRI can be potentially used for monitoring the systemic photosynthetic response connected with long-distance electrical signalling.

Published: January 2019

Despite several decades of growing interest in the concept of neurolaw in English-speaking countries, it is only a recent area of focus in Latin America. The objective of this article was to facilitate evidence-informed public policy by examining the current state of neurolaw in Latin America. To achieve this goal, this systematic review summarizes published articles, books, and book chapters, and discusses seminal legal cases in order to identify the current state of neurolaw in Spanish-speaking Latin American countries. In total, 61 publications were identified, with the majority coming from Mexico ( n = 17), Argentina ( n = 15), and Colombia ( n = 12). None of the published work identified presented empirical research, but many publications discussed complex topics such as criminal responsibility, free will, and neuroethics. The scant literature base and high concentration of publications emanating from three countries suggest that despite its growing impact abroad, more work is needed in this area in order to influence Latin America legislation and on the development of public policies. Future areas of research and policy related implications are discussed.
