Spin susceptibilities in magnetic type-I and type-II Weyl semimetals

We investigate interacting spin susceptibilities in lattice models for T -reversal symmetry-broken Weyl semimetals. We employ a random phase approximation (RPA) method for the spin-SU(2)symmetry-broken case that includes mixtures of ladder and bubble diagrams, beyond a SU(2)symmetric case. Within this approach, the relations between the tendency towards magnetic order and the band structure tilt parameter γ under different temperatures are explored. The critical interaction strength Uc for magnetic ordering decreases as the tilt term changes from type-I Weyl semimetals to type-II. The lower temperature, the sharper is the drop in Uc at the critical point between them. The variation of Uc with a slight doping near half-filling is also studied. It is generally found that these Weyl systems show a strongly anisotropic spin response with an enhanced doubly degenerate transverse susceptibility perpendicular to tilt direction, inherited from C4z rational symmetry of bare Hamiltonian, but with the longitudinal response suppressed with respect to that. For small tilts γ and strong enough interaction, we find two degenerate ordering patterns with spin order orthogonal to the tilt direction but much shorter spin correlation length parallel to the spin direction. With increasing the tilt, the system develops instabilities with respect to in-plane magnetic orders with wavevector (0, π, qz) and (π, 0, qz), with qz increasing from 0 to π before the transition to a type-II Weyl semimetal is reached. These results indicate a greater richness of magnetic phases in correlated Weyl semimetals that also pose challenges for precise theoretical descriptions.
Structures and Electronic Properties of C36 Encapsulated in Single-wall Carbon Nanotubes

The structures and electronic properties for C36 encapsulated in four single-wall armchair carbon nanotubes (C36@(n,n), n=6-9) were calculated using ab initio self-consistent field crystal orbital method based on density functional theory. The calculations show that the interwall spacing between the carbon nanotube and C36 plays an important role in the stabilities of resultant structures. The optimum interwall spacing is about 0.30 nm and the tubes can be considered as inert containers for the encapsulated C36. The Fermi levels and relative position of energy bands also have something to do with the interwall spacing. The shifts of Fermi level and C36-derived electron states modulate the electron properties of these structures. The extra electrons fill the bands of C36@(8,8) with the optimum interwall spacing almost in a rigid-band manner.
Subaperture stitching wavelength scanning interferometry for 3D surface measurement of complex-shaped optics

Subaperture stitching wavelength scanning interferometry with a high-accuracy multi-axis position stage is proposed for measuring complex surface shapes such as aspherical and freeform optics. Typical optical approaches suffer due to poor fringe visibility when it comes to complex-shaped optics. Our proposed technique allows a proper solution to this challenging issue by keeping the optical probe perpendicular to the surface slope, which provides good fringe visibility during the wavelength scan regardless of how steep the surface is. Also, the full-aperture surface map of a test sample can be obtained by stitching multiple subaperture measurement results with high precision. We tested and verified our method by measuring several representative samples and comparing the measurement results with a well-established stylus method.
Current Progress of Electrospun Nanocarriers for Drug Delivery Applications

Electrospinning is a powerful and cost-effective method that applies a strong electric field and polymer solution to fabricate versatile nanofiber using a wide array of raw materials for different biological applications. Electrospun nanofibers have developed as potential materials for the manufacturing of nanocarriers for therapeutic platforms due to controllable surface decoration, large surface areas, complex pore structure, good surface functionalization with high biocompatibility. The prominence of this technique is the possibility of merging low soluble drugs loaded in the nanofibers to enhance drug release and bioavailability. Incorporation of metal nanomaterials with electrocatalytic and/or plasmonic features into electrospun polymer nanofiber enhances thermodynamic and mechanical properties to obtain synergetic function and properties. This review discussed an overview on the theory of electrospinning, achievements and concerns, and challenges currently face in fabricating an efficient drug delivery system. Additionally, the drug-loaded into electrospun nanocarriers for drug delivery applications and opportunities, and insights into future prospects were explained.
Radius and roundness measurement of micro spheres based on a set of AFM surface scans

Micro coordinate measuring machines have been developed for the traceable characterization of small complex parts, due to the demand in research and industry. These machines require geometrically well characterized probing spheres of ever smaller radii. Currently, there is no established procedure for the measurement of such spheres below radii of 500 µm. In this paper we, therefore, propose and investigate an approach which is based on a set of atomic force microscope (AFM) surface scans in conjunction with a stitching algorithm. The strategy was implemented on a nano measuring machine and investigated on a ruby sphere with a radius of 150 µm. Although the strategy can generally be applied to the characterization of a full sphere, we limit ourselves to the measurement of one great circle (equator). The technique enables the measurement of micro spheres with a high lateral and vertical resolution. The mean radius of the ruby sphere was measured with a standard deviation of 3.7 nm over six repetitions. As our experiments have shown, the measurement procedure is at the moment mainly influenced by the shape of the AFM tip which requires further attention.
How does perceived autonomy-supportive and controlling behaviour in physical education relate to adolescents’ leisure-time physical activity participation?

In line with the tenets of self-determination theory, the current study tested associations of perceived autonomy-supportive and controlling behaviour from PE teacher with adolescents’ leisure-time physical activity (LT PA) participation, and the role of need satisfaction and need frustration, autonomous motivation and controlled motivation in PE, and perceived effort towards LT PA as mediators of these associations. Adolescents (N=381) aged between 12 and 15 years completed self-reported measures of respective constructs. Results of the structural equation modelling demonstrated that perceived autonomy-supportive behaviour from PE teachers was related to adolescents’ LT PA participation only via experiences of need satisfaction and autonomous motivation in PE, and perceived effort towards LT PA. Perceived controlling behaviour from PE teachers was found to be related to adolescents’ LT PA participation only via experiences of need frustration and controlled motivation in PE, and perceived effort towards LT PA. The current study provided evidence that perceived autonomy-supportive behaviour and perceived controlling behaviour from PE teachers contributes to adolescents’ LT PA participation through unique pathways. Findings highlight the facilitative role of autonomy-supportive behaviour from teachers in a PE context on adolescents’ LT PA participation. In addition, the beneficial role of controlled motivation in PE, although instigated by students’ perceptions of controlling behaviour from teachers and experiences of need frustration in PE, on adolescents’ LT PA participation was supported.Key words: autonomy-supportive behaviour, controlling behaviour, psychological needs, autonomous motivation, controlled motivation, leisure-time physical activity
Electroluminescence from surface oxidized silicon nanoparticles dispersed within a polymer matrix

In this work electrically induced light emission from crystalline silicon nanoparticles randomly dispersed within a polymer matrix was obtained. The observed polymer/silicon nanoparticle device electroluminescence (EL) was composed of simultaneous emission from the polymer and the silicon nanoparticles. The device emission was nonscalar and shifted from a polymer to a silicon nanoparticle dominant emission with increased current density. The device JV characteristics were bulk dominated independent of the nanoparticle loading. The nonscalar field dependence and bulk dominated carrier transport properties strongly suggest that the observed silicon nanoparticle emission was produced by an EL energy transfer process.

Estimation of a total mass transfer number from the standoff distance of a spreading flame

A realistic mass transfer number that takes into account complex modes of heat transfer is determined from the local standoff distance of a boundary layer flame. The standoff distance at each stage of the propagation and as afunction of the streamwise coordinate is obtained by means of video recordings. A previously developed theoretical model is used to calculate the standoff distance as a function of the mass transfer number ("B-number"). Comparison of the predictions with the experimental values allows extraction of the evolution of a realistic mass transfer number as a function of the streamwise coordinate. Such an evaluation can be used as an effective material flammability criterion as well as a means to determine the relative importance of different heat transfer modes during upward flame spread. Validation of this methodology is done by means of microgravity experiments that use PMMA as fuel, and a critical value of this realistic mass transfer number is consequently established as a criterion for low strain quenching of microgravity diffusion flames.
Weaving a philosophical thread linking everyday practice and theory when ‘it depends … ’

There is a phrase that social pedagogues employ time and again to characterise contextual thinking in everyday practice: ‘it depends … ’. This is often used when seeking answers akin to a formula that can be applied across situations; but can leave the listener with the thought that socio-pedagogical explanations are woolly or even incoherent. Yet when aware of context, pedagogues are clear about specific actions they take and can articulate the reasons behind such actions. What are the underlying principles, assumptions about the nature of reality, of humanity and of relationships that shape such an attitude? Dialectical epistemology and ontology assume that reality is in constant motion, that contradictions are the driver of that process of change. Further, understanding comes from highlighting relationships between different entities rather than separating them from their context. In this article, I use concepts taken from activity theory – a Marxist theory of learning using dialectical thinking – to articulate the relationship between particulars of everyday situations that are the bread and butter of socio-pedagogical practice. By showing that both activity theory and Freire’s Pedagogy of the Oppressed have the same philosophical basis, I argue that these commonalities have explanatory potential for social pedagogues when ‘it depends … ’. I hope that this will encourage practitioners interested in social pedagogy to expand their understanding of the importance of the philosophical assumptions behind their work, and join the work needed to further explore the development of social pedagogy within an activity theoretical framework.

Understanding Chinese consumers’ and Chinese immigrants’ purchase intentions toward global brands with Chinese elements

Purpose This study aims to investigate how consumers respond to global brands adapting to local elements. Specifically, this study identified three factors (i.e., cultural compatibility, cultural elements authenticity and cultural pride) affecting the purchase intentions (PIs) toward global brands using Chinese elements among Chinese consumers in China and Chinese immigrants in North America. Another aim is to examine the moderating role of acculturation in the relationship between cultural pride and PIs among Chinese immigrants. Design/methodology/approach Three studies were conducted to test the hypotheses in China and North America. Confirmatory factor analysis was used to confirm the factor structure. Hierarchical regression was used to test the main effects and moderated regression analysis was used to test the moderation effect. Findings Results show that cultural compatibility, cultural elements authenticity (CEA) and cultural pride positively affect the PIs toward global brands with Chinese elements for both Chinese consumers and Chinese immigrants. Further, among Chinese immigrants, acculturation moderates the relationship between cultural pride and PIs. Originality/value This study explored the factors influencing the PIs toward global brands using Chinese elements, filling a research gap. To the best of the authors’ knowledge, this study is the first to examine how perceived CEA affects consumers’ PIs toward global brands with Chinese elements. Further, the findings have implications for global brands that want to target Chinese consumers and Chinese immigrants in overseas markets.
Comparative Fire Behavior of Reinforced Concrete Beams Made of Different Concrete Strengths

This paper presents the comparative fire performance of reinforced concrete (RC) beams made of concretes with different strengths by undertaking fire resistance tests. Four RC beams made of normal strength concrete (NSC), high strength concrete (HSC), and ultra-high performance concrete (UHPC) with different fiber combinations, were subjected to structural loading and tested under fire conditions. Results from the fire resistance tests show that UHPC beams undergo severe fire-induced spalling and exhibit lower fire resistance as compared to HSC and NSC beams. Additionally, the inclusion of polypropylene (PP) fibers in UHPC beams aids in reducing spalling and increasing fire resistance in UHPC beams.
Gadollium Nanoparticles Delivery for Low Intensity Focused Ultrasound Diagnosis Ablation of Thyroid Cancer Therapy

Chemotherapeutic efficacy can be significantly developed nanotheranostics systems of drug delivery in tumor cells. In this work, we have demonstrated that the self-assembled by C225 conjugates Gd-PFH-NPs (C-Gd-PFH-NPs) for low intensity focused ultrasound diagnosis ablation of thyroid cancer treatment. C-Gd-PFH-NPs have shown excellent stability in PBS. Transmission electron microscopy (TEM) images also exposed the effective construction of C-Gd-PFH-NPs with commonly spherical sized assemblies. The incubation of the C625 thyroid carcinoma with C-Gd-PFH-NPs triggers apoptosis, which was confirmed by the flowcytometry analysis. The C-Gd-PFH-NPs, with remarkably displays the potent antitumor efficacy in a human C625 thyroid carcinoma xenografts. A histopathological result reveals that precisely achieved to additional confirm these outcomes. Further, we successfully examined the efficiency of C-Gd-PFH-NPs when used the thyroid carcinoma low intensity focused ultrasound diagnosis imaging (LIFUS) in vivo. These findings clearable for LIFUS agents with high performing image and different therapeutic purpose will have extensive possible for the future biomedical purposes.
Genetic Stability, Inheritance Patterns and Expression Stability in Biotech Crops

Demonstration of the stability of traits newly introduced into a plant genome via genetic engineering approaches comprise a significant portion of the safety assessment that these products undergo prior to receiving the requisite regulatory approvals enabling commercial authorization. Different regions of the world have different regulatory requirements and many ask similar questions from multiple and overlapping perspectives. The entire central dogma, that is stability at the DNA level, mRNA level and protein level, is assessed for each product, although only a few regulatory authorities request data at the mRNA level. In this article, we present inheritance data obtained during the safety assessment of biotech products representing specific transgenic events in several crop species including Brassica napus (canola); canola quality Brassica juncea (yellow seeded canola); Glycine max (soybean), and Gossypium hirsutum (cotton) in which different traits have been introduced. The data presented confirm that all events examined were nuclear insertions that resulted in typical Mendelian Inheritance patterns and that the proteins are expressed similarly across multiple generations regardless of whether they were from backcrossed or outcrossed generations. These results demonstrate that newly inserted genes are transmitted to their progeny in a stable manner similar to that of endogenous genes. Further, the findings demonstrate that assessments of multigenerational stability have very limited value to a safety assessment.
The influence of grain boundary inclination on the structure and energy of Σ=3 grain boundaries in copper

Abstract In a combined theoretical and experimental study, the energies and structures of σ = 3, [011] tilt boundaries in Cu were investigated. Equilibrium atomistic structures and grain-boundary energies were calculated by static energy minimization using an embedded-atom potential. Cu bicrystals of the same boundary orientations were fabricated by welding of Cu single crystals. Grain-boundary energies were measured by the thermal grooving technique. The atomistic structure of the {211} twin boundary was investigated by high-resolution transmission electron microscopy (HRTEM). The calculated grain-boundary energies γb plotted against the inclination of the boundary plane show a minimum for the {111} twin boundary and a second minimum at an inclination of about 82° to the {111} boundary. The calculated dependence of γb on inclination is confirmed by the measured energies over the entire range. Common to all calculated boundary structures is a microfaceting into {111} and {211} twin facets. The structures .
Prediction of phase equilibria and excess properties for systems with sulfones

The group contribution method modified UNIFAC (Dortmund) has become very popular because of its broad applications, and reliable predictions for vapor-liquid equilibria, solid-liquid equilibria, liquid-liquid equilibria, activity coefficients at infinite dilution, azeotropic data and excess enthalpies in a wide temperature range. Therefore, the existing parameter matrix for the modified UNIFAC method is continuously extended with the help of the Dortmund Data Bank and by carrying out systematic measurements. The new main group for sulfones, such as that required to describe systems with the selective solvent sulfolane, is introduced, as well as ten new pairs of group interaction parameters for modified UNIFAC.
Surface Click Reactions on Polymeric Nanocapsules for Versatile Functionalization

One-step synthesis of poly(butyl cyanoacrylate-co-propargyl cyanoacrylate) (P(BCA/PCA)) and polyurethane (PUR) azide nanocapsules for direct covalent and variable functionalization is reported. The capsules in the size range between 230 and 350 nm were synthesized in an inverse (water-in-oil) miniemulsion system through either interfacial anionic polymerization (in the case of P(BCA/PCA)) or interfacial polyaddition reaction with 2,4-toluene diisocyanate (PUR azide). Surface functionalization of nanocapsules was achieved by different copper-catalyzed azide–alkyne cycloaddition (CuAAC) reactions, which were carried out under mild and ambient conditions. Click reactions of rhodamine azide and anthracene azide to P(BCA-co-PCA) nanocapsules were performed for quantitative determination of the surface alkyne bonds. PUR-azide nanocapsules were functionalized with propiolic acid and fluorescent alkyne dye. The reaction kinetics between propiolic acid and the azide monomer was studied by 1H NMR spectroscopy. Furt.
Preparation and characterisation of multifunctional magnetic-fluorescent Fe 3 O 4 / carbon dots/silica composites

Mesoporous Fe 3 O 4 /carbon dots (CDs)/silica microspheres with large surface area, good fluorescence and magnetic property have been synthesised with as-prepared Fe 3 O 4 nanoparticles, silane-functionalised CDs and tetraethyl orthosilicate as co-precursors and cetyltrimethyl ammonium bromide as the pore-directing agent. Because of their good blue fluorescence, magnetic property and large surface areas, these particles were found to have potential in bimodal cellular imaging, drug delivery, molecular targeting and as building blocks for the assembly of complex nanostructures.
Determination of Alpha-Fetoprotein by a Microfluidic Miniature Quartz Crystal Microbalance

The determination of serum biomarkers such as alpha-fetoprotein may be employed for early diagnosis of hepatocellular carcinoma. A miniature quartz crystal microbalance integrated with a polydimethylsiloxane microfluidic device was fabricated for on-chip determination of alpha-fetoprotein. Atomic force micrographs showed that anti-alpha fetoprotein was immobilized on the gold surface of the resonator using a cross-linking method. The integrated microfluidic device determined alpha-fetoprotein with a linear range from 0.3 to 3.74 µg/mL. By using phosphate buffer containing 200 µg/mL bovine serum albumin, 0.5 M NaCl, 500 µg/mL dextran, and 0.5% Tween 20, alpha-fetoprotein was determined in the presence of 75% human serum. Additionally, high temperature treatment allowed recovery of the resonator surface allowing limited reuse of the integrated microfluidic device.
Severe pulmonary arterial hypertension and massive ascites in a patient with systemic lupus erythematosus and secondary Sjogren’s syndrome

Background Pulmonary arterial hypertension (PAH), is a rare manifestation of systemic lupus erythematosus (SLE), characterized by pulmonary arterial remodeling leading to right ventricular failure and death. To date, optimal management of SLE-associated PAH should be clarified, especially regarding the respective places of immunosuppressants and PAH vasodilator treatments. Case report We report the case of a 48-year-old woman with SLE and secondary Sjogren syndrome, associated with severe PAH and lupus peritonitis with massive ascites, who showed a remarkable response, both for SLE flare and PAH, to a treatment combining immunosuppressants and pulmonary arterial vasodilator treatment. Conclusion This observation highlights the interest of combining immunosuppressive therapy in SLE-PAH, whose modalities in association with PAH treatments should be clarified.
