Dirac half-metallicity of Thin PdCl3 Nanosheets: Investigation of the Effects of External Fields, Surface Adsorption and Defect Engineering on the Electronic and Magnetic Properties
Authors: Bafekry Asadollah , Stampfl Catherine , Peeters Francois M.
Published: January 2020

PdCl3 belongs to a novel class of Dirac materials with Dirac spin-gapless semiconducting characteristics. In this paper based, on first-principles calculations, we have systematically investigated the effect of adatom adsorption, vacancy defects, electric field, strain, edge states and layer thickness on the electronic and magnetic properties of PdCl3 (palladium trichloride). Our results show that when spin-orbital coupling is included, PdCl3 exhibits the quantum anomalous Hall effect with a non-trivial band gap of 24 meV. With increasing number of layers, from monolayer to bulk, a transition occurs from a Dirac half-metal to a ferromagnetic metal. On application of a perpendicular electrical field to bilayer PdCl3, we find that the energy band gap decreases with increasing field. Uniaxial and biaxial strain, significantly modifies the electronic structure depending on the strain type and magnitude. Adsorption of adatom and topological defects have a dramatic effect on the electronic and magnetic properties of PdCl3. In particular, the structure can become a metal (Na), half-metal (Be, Ca, Al, Ti, V, Cr, Fe and Cu with, respective, 0.72, 9.71, 7.14, 6.90, 9.71, 4.33 and 9.5 μB magnetic moments), ferromagnetic-metal (Sc, Mn and Co with 4.55, 7.93 and 2.0 μB), spin-glass semiconductor (Mg, Ni with 3.30 and 8.63 μB), and dilute-magnetic semiconductor (Li, K and Zn with 9.0, 9.0 and 5.80 μB magnetic moment, respectively). Single Pd and double Pd + Cl vacancies in PdCl3 display dilute-magnetic semiconductor characteristics, while with a single Cl vacancy, the material becomes a half-metal. The calculated optical properties of PdCl3 suggest it could be a good candidate for microelectronic and optoelectronics devices.

Insight into the antitumor actions of sterically hindered platinum(ii) complexes by a combination of STD NMR and LCMS techniques
Authors: Wang Zhimei , Fang Lei , Zhao Jian , Gou Shaohua
Published: January 2020

Sterically hindered platinum(ii) complexes have shown great advantages in overcoming platinum drug resistance. In this study, the antitumor actions of sterically hindered platinum(ii) complex 1 (cis-dichloro[(1R,2R)-N1-(2-fluorobenzyl)-1,2-diaminocyclohexane-N,N′]platinum(ii), C13H19FPtCl2) were investigated by using saturation transfer difference nuclear magnetic resonance (STD NMR) and liquid chromatography–mass spectrometry (LCMS) techniques. STD NMR was applied to study the HSA (human serum albumin) binding properties, while the interactions between guanosine 5′-monophosphate (5′-GMP) and complex 1 were studied by LCMS. For HSA binding experiments, strong STD signals were observed for protons of sterically hindered parts of carrier ligands, indicating that the sterically hindered moieties of the carrier ligand could be situated inside the binding pocket of HSA. A 19F NMR experiment indicated that complex 1 could interact with HSA. Furthermore, the binding modes of complex 1 with guanosine 5′-monophosphate (5′-GMP) were studied in the absence and presence of glutathione by LCMS. According to the HPLC profiles, a mono-functional binding mode was observed for complex 1 both in the presence and in the absence of glutathione, while a bi-adduct was observed for Pt(DACH)Cl2, which may be one of the reasons for their different biological activities. Hence, this study demonstrated that the NMR method combined with the LCMS technique could provide valuable information to understand the transport and the underlying anticancer mechanisms of the platinum(ii) complex at the molecular level. Moreover, the results reported here can help to reveal the binding mechanisms of the sterically hindered platinum(ii) compounds with biomolecules, which may shed light on the design of novel platinum(ii) anticancer agents with suitable sterically hindered groups.

The antifungal peptide CGA-N12 inhibits cell wall synthesis of Candida tropicalis by interacting with KRE9
Authors: Li Ruifang , Liu Zhengwei , Dong Weibing , Zhang Lan , Zhang Beibei , Li Dandan , Fu Caiwei
Published: January 2020

CGA-N12, an antifungal peptide derived from chromogranin A, has specific antagonistic activity against Candida spp., especially against Candida tropicalis, by inducing cell apoptosis. However, the effect of CGA-N12 on the Candida cell wall is unknown. The Candida protein KRE9, which possesses β-1,6-glucanase activity, was screened by affinity chromatography after binding to CGA-N12. In this study, the effect of CGA-N12 on KRE9 and the interaction between CGA-N12 and KRE9 was studied to clarify the effect of CGA-N12 on C. tropicalis cell wall synthesis. The effect of CGA-N12 on recombinant KRE9 β-1,6-glucanase activity was investigated by analyzing the consumption of glucose. The results showed that CGA-N12 inhibited the activity of KRE9. After C. tropicalis was treated with CGA-N12, the structure of the C. tropicalis cell wall was damaged. The interaction between CGA-N12 and KRE9 was analyzed by isothermal titration calorimetry (ITC). The results showed that their interaction process was involved an endothermic reaction, and the interaction force was mainly hydrophobic with a few electrostatic forces. The results of the fluorescence resonance energy transfer (FRET) assay showed that the distance between CGA-N12 and KRE9 was 7 ∼ 10 nm during their interaction. Therefore, we concluded that the target of CGA-N12 in the C. tropicalis cell membrane is KRE9, and that CGA-N12 weakly binds to KRE9 within a 7 ∼ 10 nm distance and inhibits KRE9 activity.
The role of HOPX in normal tissues and tumor progression
Authors: Liu Yijun , Zhang Wenling
Published: January 2020

The homeodomain-only protein homeobox (HOPX) as the smallest homeodomain protein, lacks certain conserved residues required for DNA binding. Through our literature search, we reviewed the current understandings of HOPX in normal tissues and tumor progression. HOPX was initially identified as a critical transcription factor in various normal tissues, which interacted with serum response factor (SRF) or other substance to regulate normal physiological function. However, HOPX is at a low expression or methylation level in tumors. These data indicated that HOPX may play a very important role in regulating differentiation phenotype and tumor suppressive function. We predicted the prognosis of HOPX in tumors from TCGA database and discussed the downstream genes of HOPX. To understand how HOPX is involved in the mechanisms between physical and pathological conditions could lead to novel therapeutic strategies for treatment.
The correlation between trimethylamine N-oxide, lipoprotein ratios, and conventional lipid parameters in patients with unstable angina pectoris

Published: January 2020

Purpose: Trimethylamine N-oxide (TMAO) is recently the main risk factor for coronary heart disease (CHD). Plasma lipid levels are conventionally used to predict coronary risk, but the correlation between TMAO and plasma lipid levels in unstable angina pectoris (UAP) was unclear. Our objective was to compare the plasma level of TMAO to lipoprotein ratios and conventional lipid parameters in UAP patients. Methods: A total of 114 control participants and 184 UAP patients were enrolled. Demographic characteristics were collected. Plasma levels of TMAO and lipid in all patients were measured and analyzed. The receiver operating characteristic analysis (ROC), univariate, and multivariate logistic regression analyses were carried out to examine the relationship between TMAO, lipoprotein ratios, conventional lipid parameters, and UAP. Results: The plasma levels of TMAO were remarkably increased in UAP patients (3.28 ± 1.97 µM) compared with control participants (1.52 ± 0.59 µM, P < 0.01). TMAO was significantly correlated with lipid levels in UAP patients. The ROC, univariate and multivariate logistic regression analysis both showed that the TMAO significantly increased the risk for occurrence of UAP. Conclusions: Our data indicate that the TMAO is superior to lipoprotein ratios and conventional lipid parameters in predicting occurrence of UAP.

Colorectal cancer (CRC) is the third most common malignancies in adults. Similar to other solid tumors, CRC cells show increased proliferation and suppressed apoptosis during the development and progression of the disease. Previous studies have shown that a novel tumor oncogene, spermatogenic basic helix-loop-helix transcription factor zip 1 (SPZ1), can promote proliferation. However, it is unclear whether SPZ1 plays a role in suppressing apoptosis, and the molecular mechanism behind SPZ1’s suppression of apoptosis in CRC remains unclear. Here, we found that silencing endogenous SPZ1 inhibits cell growth and induces apoptosis, and overexpression of SPZ1 promotes cell growth. These findings were corroborated by in vitro and in vivo studies. Interestingly, SPZ1 overexpressing cells were resistant to 5-fluorouracil, a drug commonly used to treat cancer. Moreover, knocking down SPZ1 led to the activation of caspase through the deregulation of Bim by ERK1/2, we found that CRC tissues had significantly higher SPZ1 and lower Bim expression, and SPZ1HBimL were associated with advanced clinical stage of CRC. Collectively, our findings demonstrate that SPZ1 contributes to tumor progression by limiting apoptosis. SPZ1 reduces apoptosis by altering the stability of Bim, suggesting SPZ1 may serve as a biomarker and therapeutic target for CRC.

Background: Allogeneic haematopoietic stem cell transplantation (HSCT) is a curative therapy for blood cancers; but results in the development of graft-versus-host disease (GVHD) in up to 70% of recipients. During GVHD, tissue damage results in ATP release into the extracellular compartment activating P2X7 on antigen-presenting cells, leading to the release of pro-inflammatory cytokines and subsequent activation of donor T cells. Therefore, the aim of the present study was to examine murine (m) P2rx7 and human (h) P2RX7 gene expression in GVHD target organs of humanised mice, and further characterise disease impact in these organs. Methods: NOD-scid IL2Rγnull (NSG) mice were injected with human peripheral blood mononuclear cells (hu-PBMC-NSG mice) or phosphate-buffered saline (PBS, control). Leucocytes were assessed by flow cytometry; gene expression was measured by quantitative polymerase chain reaction (qPCR), and tissue sections examined by histology. Results: Compared with control mice, hu-PBMC-NSG mice had increased mP2rx7 and mP2rx4 expression in the duodenum, ileum and skin. hP2RX7 was expressed in all tissues examined. hu-PBMC-NSG mice also displayed increased mReg3g expression in the duodenum and ileum, despite limited histological gut GVHD. hu-PBMC-NSG mice showed histological evidence of GVHD in the skin, liver and lung. Compared with control mice, hu-PBMC-NSG mice displayed increased ear swelling. Conclusion: Combined data revealed that P2rx7 is up-regulated in gut and skin GVHD and that P2RX7 is present in target tissues of GVHD, corresponding to human leucocyte infiltration. Data also reveal increased mReg3g expression and ear swelling in hu-PBMC-NSG mice, offering new measurements of early-stage gut GVHD and skin GVHD, respectively.

During the last two decades, the use of residential photovoltaic (PV) systems has been widely promoted by governments through various support mechanisms such as feed‐in‐tariffs, net‐metering, net‐billing, etc. These support schemes have developed a secure investment environment, increasing the penetration level of PVs in low‐voltage distribution grids. Nonetheless, increased PV integration may introduce several technical problems regarding the secure operation of distribution grids. Battery energy storage (BES) systems can mitigate such challenges, but the high capital cost is one of the most important limiting factors towards the widespread use of these systems. In fact, the financial viability of integrated PV and BES systems under different support schemes remains an open issue. In this study, the profitability of PV and BES systems is evaluated through an advanced techno‐economic model, that provides the optimal size of PV‐BES system in terms of net present value, based on the electricity production and consumption profile of the installation, PV and BES systems costs, and electricity charges. The proposed model may be a useful tool for prosumers, grid operators and policymakers, to assess the impact of various incentive policy schemes and different BES operation strategies on the economic viability of PV‐BES systems.

Graphology‐based handwriting analysis to identify human behavior, irrespective of applications, is interesting. Unlike existing methods that use characters, words and sentences for behavioural analysis with human intervention, we propose an automatic method by analysing a few handwritten English lowercase characters from a to z to identify person behaviours. The proposed method extracts structural features, such as loops, slants, cursive, straight lines, stroke thickness, contour shapes, aspect ratio and other geometrical properties, from different zones of isolated character images to derive the hypothesis based on a dictionary of Graphological rules. The derived hypothesis has the ability to categorise the personal, positive, and negative social aspects of an individual. To evaluate the proposed method, an automatic system is developed which accepts characters from a to z written by different individuals across different genders and age groups. This automatic privacy projected system is available on the website (http://subha.pythonanywhere.com). For quantitative evaluation of the proposed method, several people are requested to use the system to check their characteristics with the system automatic response based on his/her handwriting by choosing to agree or disagree options. The automatic system receives 5300 responses from the users, for which, the proposed method achieves 86.70% accuracy.

Context. Hydrogen deuteride (HD) rotational line emission can provide reliable protoplanetary disc gas mass measurements, but this molecule is difficult to observe and detections have been limited to three T Tauri discs. No new data have been available since the Herschel Space Observatory mission ended in 2013.

Aims. We set out to obtain new disc gas mass constraints by analysing upper limits on HD 1–0 emission in Herschel/PACS archival data from the DIGIT key programme.

Methods. With a focus on the Herbig Ae/Be discs, whose stars are more luminous than T Tauris, we determined upper limits for HD in data previously analysed for its line detections. We studied the significance of these limits with a grid of models run with the DALI physical-chemical code, customised to include deuterium chemistry.

Results. Nearly all the discs are constrained to Mgas ≤ 0.1 M⊙, ruling out global gravitational instability. A strong constraint is obtained for the HD 163296 disc mass, Mgas ≤ 0.067 M⊙, implying Δg/d ≤ 100. This HD-based mass limit is towards the low end of CO-based mass estimates for the disc, highlighting the large uncertainty in using only CO and suggesting that gas-phase CO depletion in HD 163296 is at most a factor of a few. The Mgas limits for HD 163296 and HD 100546, both bright discs with massive candidate protoplanetary systems, suggest disc-to-planet mass conversion efficiencies of Mp/(Mgas + Mp) ≈ 10–40% for present-day values. Near-future observations with SOFIA/HIRMES will be able to detect HD in the brightest Herbig Ae/Be discs within 150 pc with ≈ 10 h integration time.

Published: January 2020

At present, bio-inspired geomagnetic navigation is mostly based on evolutionary strategy, which requires long navigation time and low efficiency. To solve this problem, a bio-inspired geomagnetic navigation method for AUV based on evolutionary gradient search is proposed. Combining the bionic evolutionary search algorithm with the classical gradient algorithm to search the function extremum can not only ensure the global optimization of the search, but also have fast convergence, which can improve the efficiency of bio-inspired geomagnetic navigation. The simulation results show that this method does not need prior geomagnetic information and can complete navigation tasks according to the geomagnetic trend. Comparing with the evolutionary search strategy, the effectiveness and superiority of the evolutionary gradient search strategy are verified.
Cramér-Rao Lower Bound of Target Localization Method Based on TOA Measurements
Authors: Du Jinxiang , Zhang Benmao
Published: January 2020

The Cramér-Rao bound of target localization method based on time-of-arrival measurements is analyzed. For the localization error analysis, the CRLB is derived under the assumptions that the measurement errors are independent and characterized by zero-mean Gaussian distributed process with identical variance, which is not satisfied in the situation of localizing noncooperative targets. Cramér-Rao bound is deduced by using the fact that the variances of TOA measurements of different sensors are affected by the signal-to-noise ratio of the echo signal and are different from each other. Simulations of Monte Carlo experiments are carried out so as to verify the analytical results.
Uncertainty Analysis of Supersonic Biplane's Aerodynamic Characteristics
Authors: Zhu Hongyu , Wang Gang , Liu Yi , Ma Boping
Published: January 2020

Utilizing the interference of shock and expansion waves, supersonic biplane can reduce the wave drag remarkably. However, the supersonic biplane is only designed at special conditions, so that it has poor performance at off-design conditions. To analyze supersonic biplane's aerodynamic characteristics at off-design conditions, the non-instructive probabilistic collocation method has been employed to achieve uncertainty quantification. Besides, Sobol global sensitivity is adopted to accurately evaluate the influence of the input uncertainty parameters. The uncertainty parameters are Mach number and the angle of attack which both satisfy special normal distributions. Aerodynamic coefficients and pressure distribution from the biplane's surface as well as flow filed are studied. The results of uncertainty quantification show that the main reason for aerodynamic characteristics fluctuations is the pressure pulsation from the maximum thickness of the lower airfoil's upper surface. The results of global sensitivity show that Mach number is the most important factor for the variation of aerodynamic performance.

Published: January 2020

A new diagnosis method of Lurie system stability by using Chaotic time series data was proposed in order to solve stability analysis of flight control system with fault and uncertain. Firstly, the reasons for the instability of the nonlinear system of Ruri leaf was analyzed by using the small gain theory and linear matrix inequalities in the robust control theory. And the stability conditions of Rui leaf system under the condition of uncertainty and failure were proved theoretically. In order to quantify the stability of nonlinear systems in complex Ruri leaves, based on the theory of phase space reconstruction, the nonlinear Ruri system with continuous discrete characteristics was converted into an approximate time discrete equation, mapping it to a low dimensional primitive space, by introducing Q Gauss function into Kernel function, the generalization ability of neural networks are enhanced, realizing the stability analysis method based on the characteristic of primitive migration, which is suitable for various fault and uncertainty conditions, and the relative quantized stability norm can be given. The simulation shows that the present method can effectively solve the stability analysis and determination of flight control system under various factors.

Published: January 2020

To predict accurately the dynamics performance of planetary roller screw mechanism, it is necessary to establish its streamline and engineering-compliant dynamic model, which is the basis of mechanical design and precision control of the system. In this paper, the relative displacement between roller and ring gear along the line of action is deduced and the relationship between nature frequencies and the number of rollers is discussed. Considering the torsional stiffness of all components and the thread mesh stiffness based on the Hertzian contact theory, the purely torsional model for planetary roller screw mechanism is presented to reveal the natural frequencies and vibration mode characteristics of the system. The results show that the natural properties of undamped system in planetary roller screw mechanism are mainly reflected by two typical vibration modes: rotational mode and roller mode.
