Authors: Gendron Nicolas , Flament Héloïse , Litvinova Elena , Ortuno Sofia , Ajzenberg Nadine , Faille Dorothée
Published: September 2019

Idarucizumab is a humanized antigen binding fragment (Fab) of a recombinant anti-dabigatran monoclonal antibody (IgG1-kappa) that allows rapid and sustained reversal of dabigatran-induced anticoagulation in case of bleeding or urgent surgery. Herein, we report a very unusual case of dabigatran reversal by idarucizumab in a 79-year-old woman with acute kidney failure admitted to a hospital in a context of hemoptysis. Three repeated injections were necessary because of massive dabigatran overdose and high rebounds of dabigatran plasma concentration. Idarucizumab was found on urine immunofixation up to 6 days after the last injection where it reacted with anti-kappa light chain antibody, but not with anti-gamma heavy chain antibody. Physicians should be aware of the increased half-life of idarucizumab in this context of acute kidney impairment and of its interference with urine immunofixation because it could lead to false-positive results and misdiagnosis of a paraprotein.

Published: September 2019

Germanane (GeH) is a hydrogen-terminated layered crystal of germanium. We fabricated an electric double layer transistor (EDLT) on a GeH thin film on the Ge (111) substrate and investigated its electronic properties. The EDLT showed ambipolar transfer characteristics at 240 K. The sheet resistance Rsheet at null gate bias (VG = 0 V) exceeded 1 MΩ below 100 K, which indicates an insulating behavior. For VG = −2 V (hole accumulation), a gradual increase in Rsheet up to 10 kΩ was found upon decreasing temperature to 40 K, i.e., semiconducting or even weakly insulating. Remarkably, Rsheet for VG = 1 V (electron accumulation) decreased down to 3 kΩ upon decreasing temperature to 40 K, indicating metallic conduction. Accumulation of electrons (holes) was confirmed for VG > 1 V (VG < −1 V) by Hall effect measurements. Hall mobilities of electrons and holes, which increase with decreasing temperature, were 6500 cm2 V−1 s−1 and 570 cm2 V−1 s−1, respectively, at 120 K.

Published: September 2019

Torch-plasma-grown single-walled carbon nanotubes (SWCNTs) are integrated with regioregular poly(3-hexylthiophene) (P3HT) and a fullerene derivative 1-(3-methoxycarbonyl) propyl-1-phenyl[6,6]C61 (PCBM) as a hybrid photoactive layer for bulk heterojunction solar cell devices. We demonstrate that molecular information could be accurately obtained by time-of-flight secondary ion mass spectrometry throughout the hybrid organic photoactive solar cell layers when sputtering is performed using a Cs+ 2000 eV ion source. Furthermore, the photovoltaic (PV) performance of the fabricated devices show an increase in the short-circuit current density (Jsc) and the fill factor (FF) as compared to the pristine devices fabricated without SWCNTs. The best results are obtained with 0.5 wt. % SWCNT loads, where an open-circuit voltage (VOC) of 660 mV is achieved, with a Jsc of 9.95 mA cm−2 and a FF of 54%, leading to a power conversion efficiency of 3.54% (measured at standard test conditions, AM1.5 g). At this optimum SWCNT concentration of 0.5 wt. %, and to further understand the charge-transfer mechanisms taking place at the interfaces of P3HT:PCBM:SWCNT, Jsc is measured with respect to the light intensity and shows a linear dependency (in the double logarithmic scale), which implies that losses in the charge carrier are rather governed by monomolecular recombination. Finally, our results show that our hybrid devices benefit from the fullerene electron accepting nature and from the SWCNT fast electron transportation feature that improve substantially the exciton dissociation efficiency. The influence of the SWCNTs on the Fermi level and the work function of the photoactive composite and its impact on the PV performance is also investigated.

Published: September 2019

Acoustically-driven ferromagnetic resonance (ADFMR) has recently emerged as a powerful scientific test-bed toward understanding complex interactions between phonons and magnons. In this technique, a traditional surface acoustic wave (SAW) delay-line filter interfaces with a ferromagnetic thin-film which can be driven into precession at the ferromagnetic resonance (FMR) frequency by the SAWs. SAW filters are used extensively in industry, but in the context of ADFMR, their design considerations are largely absent from the literature. We produced a variety of ADFMR devices by systematically changing parameters including the material and the number of pairs of interdigital transducers, the ferromagnetic thin-film growth technique, and the presence or the absence of a capping layer on the ferromagnetic thin-film. We quantitatively compare results by adapting traditional ferromagnetic resonance techniques. This work describes the parameters relevant to the development and optimization of SAW-driven FMR.

Published: September 2019

Concentric spoof surface plasmon hybridization in the microwave frequency is physically realized with subwavelength plasmonic metamaterials. The hybridization is generated with two concentric spoof localized surface plasmon (LSP) particles, where the overlap of the two spoof LSP particles could be tuned to manipulate the resonance. Such spoof plasmon hybridization could increase the Q factor effectively up to 965, and decrease the electric dimension of the particle down to 1/7 wavelength. The coupled-resonator circuit theory is applied to analyze the interaction mechanism of the structure with strong electric and magnetic coupling. Near electric-field distributions are mapped in the simulation and experiment to characterize the resonant property. Both the bonding mode and the antibonding mode are observed. A free space measurement system is adopted to improve the measurement of the spoof LSP resonant spectra.
Lattice Boltzmann electrokinetics simulation of nanocapacitors

Published: September 2019

We propose a method to model metallic surfaces in Lattice Boltzmann Electrokinetics (LBE) simulations, a lattice-based algorithm rooted in kinetic theory which captures the coupled solvent and ion dynamics in electrolyte solutions. This is achieved by a simple rule to impose electrostatic boundary conditions in a consistent way with the location of the hydrodynamic interface for stick boundary conditions. The proposed method also provides the local charge induced on the electrode by the instantaneous distribution of ions under voltage. We validate it in the low voltage regime by comparison with analytical results in two model nanocapacitors: parallel plates and coaxial electrodes. We examine the steady-state ionic concentrations and electric potential profiles (and corresponding capacitance), the time-dependent response of the charge on the electrodes, and the steady-state electro-osmotic profiles in the presence of an additional, tangential electric field. The LBE method further provides the time-dependence of these quantities, as illustrated on the electro-osmotic response. While we do not consider this case in the present work, which focuses on the validation of the method, the latter readily applies to large voltages between the electrodes, as well as to time-dependent voltages. This work opens the way to the LBE simulation of more complex systems involving electrodes and metallic surfaces, such as sensing devices based on nanofluidic channels and nanotubes, or porous electrodes.

Published: September 2019

Two-dimensional (2D) materials on flexible substrates have shown unique applications due to their excellent mechanical related properties. Here, single crystalline, high quality, and continuous 2D antimony (Sb) thin films on SiO2 and flexible polydimethylsiloxane (PDMS) substrates are prepared by the vapor deposition method. Temperature-dependent Raman spectra of the Sb thin film on PDMS and SiO2 substrates are studied, which indicates that there is a strong temperature-strain coupling between the Sb thin film and PDMS substrates. In order to further study the coupling interaction, the temperature-dependent phonon frequency is deeply investigated, ranging from 193 K to 393 K. Moreover, the strain-dependent phonon frequency of 2D Sb is calculated by the first-principles method based on density functional theory and compared with experimental results. We find that the biaxial strain in the Sb thin film on the PDMS substrate is about 0.225% for each change in the temperature of 100 K. This provides an effective method to study and control the physical properties of 2D materials.

Authors: Neuenschwander B. , Jaeggi B. , Zavedeev E. V. , Arutyunyan N. R. , Pimenov S. M.
Published: September 2019

In this paper, we have investigated the burst mode (BM) ablation and surface structuring of diamondlike nanocomposite (DLN) a-C:H:Si:O films with femtosecond laser pulses (wavelength λ = 515 nm, pulse duration τ = 320 fs, and pulse repetition rate f = 100 kHz) under different scanning conditions (single spots and linear structures). The pulse separation in the bursts is 25 ns (intraburst frequency f = 40 MHz), and the pulse number is varied from 1 to 8. The ablation depth and specific ablation rates (μm3/μJ) are found to be higher for the burst mode compared to single-pulse irradiation, increasing with the pulse number in the burst. The obtained experimental data of the higher ablation efficiency are shown to correlate with computer simulations of the BM ablation. In correlation with the ablation findings, Raman spectra of single spots and microgrooves have evidenced a growing graphitization of the amorphous film structure with the pulse number in the bursts (at an equal energy deposited into the films). Contact-mode atomic force microscopy (AFM) is applied to reveal an influence of the BM processing on the surface properties (nanoscale relief, friction) of laser-structured films. Based on the ablation and Raman data analysis, AFM examination of ablated/redeposited layers, and computer simulations of the burst mode ablation, the heat accumulation is identified as the main factor responsible for the enhanced ablation efficiency during the BM processing of DLN films. In addition, results of the high precision surface microstructuring of DLN films in the burst mode are presented.
Interferometric measurements of static and dynamic dipole polarizability of titanium atoms using fast electrical explosion of fine metal wires in vacuum
Authors: Sarkisov G. S. , Hamilton A. , Sotnikov V. I.
Published: September 2019

The rapid electrical explosion of fine metal wires in vacuum generates gas cylinders of metal atoms surrounded by low-density and fast-expanding plasma corona. For fully vaporized wires, we utilize the integrated-phase technique, based on laser interferometry, to measure the dynamic dipole polarizability of metal atoms. Titanium wire with a diameter of 20 μm and a length of 1 cm was rapidly vaporized by a fast-rising current at ∼10 ns. We find that the dynamic dipole polarizability of titanium atoms equals 20.5 ± 2 Å3 for 532 nm and 10.6 ± 1 Å3 for 1064 nm. The wire reaches a totally vaporized state when the expansion velocity in a vacuum is ∼5.5 km/s. To vaporize Ti wire, the deposited Joule energy exceeded tabulated enthalpy of atomization by ∼2.8 times. Two-wavelength diagnostic allows reconstruction of the static dipole polarizability 9.13 ± 1.7 Å3 and electron transition energy 3.13 ± 0.2 eV with the corresponding transition wavelength of 396.6 ± 26 nm. This reconstructed wavelength matches to the group of strong dipole-allowed atomic spectral lines for Ti between 394.87 and 402.46 nm for ground-state transitions 3d24s2.

Published: September 2019

Unpalatable plants reportedly serve as a biodiversity refuge. However, few studies have been conducted to evaluate how unpalatable plants impact vegetation composition in alpine ecosystems. In the present study we investigated alpine meadows at four sites in four different prefectures on the eastern Qinghai-Tibetan Plateau of Qinghai Province, China. The study sites included meadows grazed by livestock (AO) and others in the vicinity colonised by the unpalatable grass, Achnatherum inebrians (AI), which the livestock avoided. The results showed: (1) palatable graminoid species were significantly different in the two groups: AO plots were dominated by Kobresia spp. (sedges), whereas AI plots were dominated by Poa pratensis and Elymus nutans (grasses); (2) graminoid diversity was significantly higher in AI than in AO plots; (3) grasses had significantly more seeds in AI than in AO plots. We suggest a three-step process for the invasion of A. inebrians into overgrazed alpine meadows in Northern China. First, soil is disturbed by rodents. Second, disturbed soil is invaded by A. inebrians. Third, the A. inebrians community is colonised by palatable grasses such as Elymus, Poa, Leymus and Stipa spp.
Vegetative reproduction and root anatomy of Solanum centrale J.M.Black (Australian bush tomato)

Published: September 2019

The aim of this study was to describe the morphology, anatomy and function of underground structures associated with colonies of Solanum centrale J.M.Black (Australian bush tomato), a perennial sub-shrub found in arid areas of Australia and an important traditional staple food for Aboriginal people. It is known that this species forms clonal communities, but there is little understanding of the mechanisms of formation in either natural or cultivated situations. The underground connections within seven clonal communities from Central and South Australia were documented and samples of secondary roots, thick lateral roots and stems were examined under both laboratory and glasshouse conditions. Clonal communities were observed at all sites with individual ramets arising from lateral roots (root-suckers) that ranged from 2–10 mm in diameter growing in a network 5–15 cm below the soil surface. Lateral roots have dicotyledonous root anatomy and rapidly resprout to form new clonal ramets. They also have the capacity to accumulate starch in parenchyma cells. The morphology and root-suckering ability resemble those of weedy Solanum spp. from other parts of the world, as well as species from a variety of genera adapted to arid climates. Methods to capitalise on the ability of lateral roots to form clonal ramets in cultivated situations, particularly given the difficulties in establishing crops from seed, are discussed.
Beneficial land sector change in far northern Australia is required and possible – a refutation of McLean and Holmes (2019)
Authors: Russell-Smith Jeremy , Sangha Kamaljit K.
Published: September 2019

In a recent paper we set out a case for extending current and emerging ecosystem services enterprise opportunities to support sustainable land sector development in far northern Australia (Russell-Smith and Sangha 2018: The Rangeland Journal 40, 315–330. doi:10.1071/RJ18005). In that paper we illustrate very significant economic viability and environmental sustainability issues associated with the current dominant land use, the extensive rangeland beef cattle industry. Our beef enterprise economic assessments drew heavily on reports by Ian McLean, Phil Holmes and colleagues, as well as various other authoritative studies. In a detailed response, McLean and Holmes outline their concerns that, in various instances, we misrepresented their data and that our assessment ‘does not accurately portray the economic performance and contribution of the pastoral sector in northern Australia, nor justify the conclusion that fundamental land sector change is required’ (Comment by McLean and Holmes 2019: The Rangeland Journal, 41, 157–160. doi:10.1071/RJ18098). We acknowledge the singular contributions of those authors for our understanding of the enterprise characteristics and challenges faced by northern beef producers, but further, we: (a) for context, demonstrate the magnitude of the economic and sustainability challenges faced by the majority of northern beef producers as described in a range of pertinent studies including their own; (b) provide a detailed refutation of all eight of their listed concerns; and (c) conclude that available evidence does in fact strongly support the need for exploring diversified enterprise opportunities towards developing a sustainable and inclusive far northern land sector.

Published: September 2019

We report on the generation of optical pulses with a nearly one octave-spanning spectrum ranging from 1300 nm to 2500 nm at 1 kHz repetition rate, which are based on intra-pulse difference frequency generation (DFG) in β-barium borate crystal (β-BBO) and passively carrier-envelope-phase (CEP) stabilized. The DFG is induced by few-cycle pulses initiated from spectral broadening in multiple thin plates driven by a Ti: sapphire chirped-pulse amplifier. Furthermore, a numerical simulation is developed to estimate the conversion efficiency and output spectrum of the DFG. Our results show that the pulses from the DFG have the potential for seeding intense mid-infrared (MIR) laser generation and amplification to study strong-field physics and attosecond science.
Propagation of dark soliton interacting with domain wall in two immiscible Bose–Einstein condensates*
Authors: Zheng Lang , Zhang Yi-Cai , Liu Chao-Fei
Published: September 2019

Reflection and transmission are two behaviors of wave propagating to an interface. The immiscible binary mixtures of Bose–Einstein condensates can form the symmetry-breaking state, in which the domain wall on the center can serve as the interface. In this study, we explore in detail the propagation of a dark soliton interacting with the domain wall in the harmonic trap. We find that the low-energy dark soliton is easy to form the transmission and the high-energy dark soliton trends to reflect from the domain wall. Both reflection and transmission of dark soliton on the domain wall induce the sound radiation. But the sound radiation in the reflection derives from the collective oscillation of condensates, and it in the transmission comes not only from the collective oscillation, but also from the condensate filling in the dark soliton.

Published: September 2019

The nitrogen assimilation pathway in cassava was reconstructed by comparative genomics approach to understand the underlying metabolism as well as the interaction between carbon and nitrogen assimilation towards the synthesis of metabolic phenotype. First, theproteins of cassava were annotated via sequence similarity search against genes of 11 template plants obtained from KEGG and PMN databases, employing reciprocal BLASTp(E-value ≤ 1x10−10, identity percentage ≥ 60, and coverage percentage ≥ 80). The template plants comprised well-known plant, starchy crops, nitrogen-fixing crops and crops that are evolutionarily related to cassava and includedArabidopsis thaliana, Oryzasativa, Zea mays, Ricinuscommunis, Solanumtuberosum, Brassica rapa, Cicerarietinum, Jatrophacurcas, Medicagotruncatula, Phaseolus vulgaris and Glycine max.The pathway was then curatedwith reactions obtained from the CassavaCyc database to ensure full pathway connectivity.It was subsequently validated with cloned sequence of cassava from the GenBank and cassava transcriptome data from literature. The resulting N-assimilation pathway, covering the conversion of nitrate to amino acids (glutamine and glutamate),consists of 14 biochemical reactions corresponding to 59 genes, 73 proteins and 2 transport reactions. At least 92 percent of the identified proteins in the pathway were supported by the transcriptome data. In addition, the proposed N-assimilation pathway contains four additional enzymes, including glutamate synthase, nitrilase, formamidase and carbamoyl phosphate synthasecompared to the existing N-assimilation pathway in CassavaCyc database. Taken together, the N-assimilation pathway herein proposed identified reactions involved in N-assimilation and represents a forward step towards understanding metabolic basis for cassava yield as well as its phenotypic plasticity and adaptation to stress.

Barium borophosphate glass and bismuth borophosphate glass doped with 1 mol% dysprosium oxide were synthesized by melt-quenching technique at 1200 °C for 3 hrs. Both glasses were studied optical and luminescence properties to evaluate their potential for using as luminescence materials. The absorption spectra in the region of ultraviolet, visible and near-infrared from 300 to 2000 nm wavelength were investigated. The luminescence spectra showed the strong emission band at 573 nm (4F9/2 → 6H13/2) under 350 nm excitation wavelength, which the shapes of the emission bands are similar in both glasses.

The research aimed to study the radiation shielding properties of xBaO-5WO3-15Na2O-(80-x)B2O3 glass system where x = 5, 10, 15, 20, 25, 30 and 35 mol%. The theoretical values calculated using WinXCom program in the range of 1 keV to 100 GeV energy regions. The results of calculation found that the mass attenuation coefficients were increased with increase in BaO concentration and decreased with the increasing energy. Moreover, these glass system at low energies show discontinuities corresponding to photoelectric absorption edges of tungsten and barium. For the partials interaction at the low energies range the photoelectric absorption is the main interaction in these energy regions. At the medium energy regions, the radiation shielding parameters are almost constants dominated by Compton scattering process. In the high energy regions, pair production becomes the main interaction process over the energy. It can also be concluded that the characteristics of radiation shielding parameters for the glasses system depend on different barium in this concentration and the energy regions. The lead equivalent thickness of glass samples show that glass samples increasing trend with increase in concentration of BaO and the experimental are good agreement with theoretical value.

The effect of paramagnetic implant on magnetic resonance imaging (MRI) is important subjects in medical material studies. The purpose of this study is to investigate the effects of PAlNaGd doped with europium with the chemical composition of (60-x) P2O5: 10 Al2O3: 20 Na2O3: 10 Gd2O3: x Eu2O3, when x = 0.1 and 3.0 mol% on MR imaging. The glass was placed in phantom as to mimic in effect of material implant in human tissue. The results of this study show that artifacts severity depends on the europium ions (Eu3+) concentration and T2-weighted images is more effected than that of T1-images. The T2 relaxation time is also found to be affected by the Eu3+ concentration in the glass, causing the T2 relaxation time to become shorter. This current study found that PAlNaGd glass shows high magnetic susceptibility effects and modifies T2 relaxation time making it an interesting material for use as a medical implant and device.

Authors: Chueachot Romteera , Nakhowong Ronariddh
Published: September 2019

Lead titanate (PbTiO3) nanorods with diameters ranging between 300 and 450 nm were synthesized using a combination of the electrospinning and calcination processes. The XRD patterns showed that the crystalline phases were in good agreement with tetragonal PbTiO3. Crystallite size, lattice parameters, cell volume, tetragonality, and X-ray densities increased with increasing calcination. SEM and TEM images revealed the morphology of the PbTiO3 nanorods as rough with combined nanograins varying in size between 70 and 130 nm. The band gap energy of PbTiO3 was determined to be in the range of 2.82-2.86 eV, demonstrating that calcination influenced the crystallinity, morphology, and band gap energy of the PbTiO3 nanorods.
The free energy of compressed lattice knots
Authors: Janse van Rensburg EJ
Published: September 2019

IOP Publishing has withdrawn this article upon the author's request due to several issues with the mathematical content.

The osmotic pressure of monomers in a knotted ring polymer in a confining cavity is modelled by a lattice polygon confined in a cube in ${\mathbb Z}^3$. These polygons can be knotted and are called lattice knots. In this paper the GAS algorithm \cite{JvRR11} is used to estimate the free energy of lattice knots of knot types the unknot, the trefoil knot, and the figure eight knot, as a function of the concentration of monomers in the confining cube. The data show that the free energy is a function of knot type at low concentrations, and (mean-field) Flory-Huggins theory \cite{Flory42,H42} is used to model the free energy as a function of monomer concentration. The Flory interaction parameter of lattice polygons in ${\mathbb Z}^3$ is also estimated. At critical values of the concentration the osmotic pressure may vanish, and these critical concentrations, suitably rescaled, is dependent on knot type.
Bandstructure Effects in the Electronic Transport of Silicon Nanowire in [100] and [110] Transport Orientations
Authors: Kumar Manoj , Kumar Lamba Vijay
Published: September 2019

An electronic transport study about band structure effects of silicon nanowire (Si-NW) in [100] and [110] transport orientations has been done. A dispersion calculation has also been done for a sp3d5s* hybridized atomistic model along with a Poisson solver. A ballistic model has been used for the evaluation of I-V characteristics. For [100] and [110] transport-oriented nanowires, the total gate capacitance was decreased by 30%. The carrier velocity was affected by both [100] and [110] transport-oriented nanowires. The velocities depend on degeneracy and effective mass of the dispersion. In our study, we have used 3nm thick nanowire oriented in [100] and [110] directions. The [100] oriented nanowire gives better ON-current performance as compared to [110] oriented nanowire. We have studied the valley splitting effects which can lift the degeneracies of 3nm wires. The effective mass which changes with various transport orientations and quantization, was increased with quantization for [100] while it was decreased for [110] transport orientated nanowire.

A single switch single stage 24watt power supply is presented to run a light emitting diode (LED) load. In this power supply, the Zeta converter is used to operate in continuous conduction mode (CCM) for maintaining desired output voltage. A proportional integral (PI) controller is also proposed in the feedback to make system stable. The need of proposed controller is justified from stability analysis of the system with the help of small signal average modeling. A simulation model of the proposed LED driver is also carried out in MATLAB/SIMLINK using sim-power toolbox environment for a universal ac input mains. The results confirm a constant current of 0.4amp at output with improved power quality parameters such as total harmonic distortion (THD) and power factor (PF). All outcomes lie under the limit of IEC 61000-3-2 standards that verifies the theoretical analysis.

Authors: Kumar Verma Mandhir , Kumar Yadav Vinod , Mukherjee V.
Published: September 2019

Utmost of elucidation about the research accomplished in an article is cleared from the objective function of the planning problem. An objective function is a mathematical expression which describe the existing condition of a system with numerous variables, in which alteration of these variables result in optimized value largest or smallest, depending on problem or desired value. That value may be obtained by minimizing or maximizing the objective function. In this paper, a review has been carried out on objective functions of distribution network expansion planning (DNEP). These objective functions have been classified into five main categories: financial, income related, technical, optimal size & location and social & economic. The selection of objective function clearly shows increasing penetration of distributed generation (DG), distributed energy storing systems (DESS) and fuel cells with renewable technologies. Most of the reviewed articles highlight these objectives in details, however; not all fields have been covered in any single work on DNEP. This review article aims to address this gap so that widespread DNEP can be achieved with flawlessness. Substantial information has been offered of research work done in the field of DNEP through this review article which will mitigate the impending researchers from the difficulties of getting apposite supervision.

Published: September 2019

3D printers are being explored by many of the industrial giants and daily customers as an excellent replacement for some of the traditional, inefficient, costly and waste producing techniques of manufacturing. Although, still at a premature state of development, and being thoroughly researched upon, there is lack of data concerning the physical strength or a proper machine design development for this 3-axis automated machine. Other, while being able to create a robust machine, over-utilize the resources. In this paper, we attempt to explore how analysis of vibration using minimal equipment could refine the quality of 3D printing as well as how would one improve the design to yield best results. The study is most relevant for the online open source community e.g. RepRap, within the development in new 3d printers design.
