description: Superconductivity in topological materials has attracted a great deal of interest in both electron physics and material sciences since the theoretical predictions that Majorana fermions can be realized in topological superconductors [1-4]. Topological superconductivity could be realized in a type II, band-inverted, InAs/GaSb quantum well if it is in proximity to a conventional superconductor. Here we report observations of the proximity effect induced giant supercurrent states in an InAs/GaSb bilayer system that is sandwiched between two superconducting tantalum electrodes to form a superconductor-InAs/GaSb-superconductor junction. Electron transport results show that the supercurrent states can be preserved in a surprisingly large temperature-magnetic field (T-H) parameter space. In addition, the evolution of differential resistance in T and H reveals an interesting superconducting gap structure.

description: The cooking act is one of the primary sources of indoor air pollution. Frying is one of the oldest food processing methods that has received much attention in studies due to various pollutants. Oxidation of oil via the raising of temperature leads to the formation of alkadienals, known as precursors of monoaromatics hydrocarbons, such as benzene and toluene ethylbenzene, and xylene isomers (BTEX). The compounds have carcinogenic effects on human health and cause environmental effects by forming secondary organic aerosols (SOA) and ozone. Within this regard, many studies assessed the emission of the chemicals at the indoor area, stacks of commercial kitchens, and emission points, while they considered the effects of various factors like oil temperature, oil type, and additions on the formation of BTEX and another VOCs. Temperature as an accelerator factor has a direct relationship, while time has not shown specific emissions. The oils depend on their compositions, have different oxidative stability. Indeed, the oils with higher unsaturated contents are more susceptible to oxidation. Among unsaturated fatty acids, polyunsaturated than monounsaturated types have a higher oxidation rate. However, foods/additives can vary frying content compositions and influence emissions. In this paper, we attempt to review the measurement procedures, influential factors on formation and methods to assess the environmental and health impacts of BTEX.

description: The removal of methylene blue (MB) and maxilon yellow (MY) dyes from aqueous solutions was investigated by an adsorption process using spent Salvia officinalis (SSO) for the first time. The operating conditions and mechanisms for the MB-SSO and MY-SSO adsorption systems were determined. FTIR-ATR and SEM-EDAX analyses were also performed to characterise the adsorbent. Optimum conditions in each system were similarly obtained, excluding pH (5.7 for MB and 6.5 for MY). The dye removal efficiency was 78% for MB and 56% for MY. It was observed that experimental data fits Freundlich isotherm (R2 ≈ 0.97) and pseudo-second-order kinetic (R2 ≈ 0.99) model in both systems. The maximum adsorption capacities of SSO for MB and MY dyes were determined as 16.53 and 11.79 mg g−1, respectively. The pseudo-second-order kinetic model revealed that adsorption efficiency was affected by a number of active sites on the adsorbent and the concentration of the dye. The thermodynamic parameters confirmed that adsorption was spontaneous, exothermic and physisorption in both adsorption systems. The results indicate that SSO can be used as a promising adsorbent material for removal of MB and MY dye from aqueous solutions. However, in order to remove high dye concentrations, SSO must be activated.

description: In this paper, Al2O3 nanoparticles with an average crystallite size of 35.56 nm are facilely synthesised using the combustion procedure in the presence of glutamine as organic fuel. Besides, Al2O3/Sodium dodecyl sulphate/2-aminophenol composite is synthesised and applied as a novel adsorbent for the removal of Pb(II), Cd(II), and Co(II) ions from aqueous media. The synthesised samples are characterised using several tools such as X-ray diffraction (XRD), elemental analysis, Fourier-transform infrared spectroscopy (FT-IR), and field emission scanning electron microscopy (FE-SEM). In the case of Al2O3, the XRD peaks, which were appeared at 2θ of 38.11, 46.21, and 66.72°, are attributed to the (311), (400), and (440) planes of γ-Al2O3, respectively. In the case of Al2O3/Sodium dodecyl sulphate/2-aminophenol composite, the existence of a wide XRD peak at 2Ɵ = 25° confirming that the crystal assembly of Al2O3 combined or interfered over amorphous organic surroundings. Elemental analysis of the Al2O3/Sodium dodecyl sulphate/2-aminophenol composite displayed that the % C, % H, and % N are 17.23, 4.21, and 1.58%, respectively. The maximum adsorption capacity, which was obtained from Langmuir isotherm, of the composite towards Pb(II), Cd(II), and Co(II) ions is 119.19, 101.21, and 86.51 mg/g, respectively. The best description for the experimental results is given by the pseudo-second-order kinetic model and Langmuir adsorption isotherm. Also, the thermodynamic parameters confirmed that the removal of studied ions is spontaneous, exothermic, and chemical. After three adsorption-desorption cycles, 25%V/V (Methanol/HNO3) is the suitable desorbing medium needed for the recapture of the adsorbed metal ions on the composite. Hence, the synthesised composite could be reutilised without notable losses of its effectiveness.

description: We revisit the small field Coleman-Weinberg (CW) inflation, which has the following two problems. First, the smallness of the slow roll parameter $ε$ requires the inflation scale to be very low. Second, the spectral index $n_s \approx1+2 η$ tends to become smaller compared to the observed value. In this letter, we consider two possible effects on the dynamics of inflation: radiatively generated non-minimal coupling to gravity $ξϕ^2 {\cal R}$ and condensation of fermions coupled to the inflaton as $ϕ\barψψ$. We show that the fermion condenate can solve the above problems.

Многие проблемы, неразрешимые при постановке реальных экспериментов, при компьютерном моделировании оказываются легко устранимыми, повышая наглядность и научно-теоретический уровень изложения материала. Виртуальная реальность дает возможность моделировать перенос в пространстве и во времени, а также осуществлять наглядные трансформации объектов не только макро-, но и микромира. Приобретаемые при этом знания, умения, новый опыт могут играть существенную роль в развитии, становлении человека и как профессионала, и как личности в целомToday, it is relevant to use teaching techniques and methods that combine the principles of problematicity and modeling of professional activity, form the ability to independently acquire new knowledge, collect the necessary information. Many problems which are insoluble in the formulation of real experiments in computer modeling can be easily eliminated, increasing the visibility and scientific-theoretical level of presentation of the material. Virtual reality makes it possible to simulate transport in space and time, as well as to carry out visual transformations of objects not only in the macrobut also in the microworld. The knowledge, skills and new experience acquired at the same time can play a significant role in the development and formation of a person both as a professional and as a person as a whole.

description: We study the variance and kurtosis of the net-baryon number in a fluid dynamical model for heavy-ion collisions. It is based on an effective chiral model with dilatons for the strong coupling regime of QCD. Taking into account spinodal instabilities, we demonstrate that this model exhibits a diverging quark number susceptibility and kurtosis all along the spinodal lines of the first-order phase transition, with a change of universality class at the critical end point. During the (3+1) dimensional expansion of a hot and dense fireball, instabilities are created by fluctuations in the explicitly propagated chiral and dilaton field. We find a clear enhancement of event-by-event fluctuations of the baryon number at the critical point and first-order phase transition in comparison with an evolution through the crossover region.

description: We present results from a survey designed to probe the star formation properties of 32 damped Ly-alpha systems (DLAs) at z~2.7. By using the "double-DLA" technique that eliminates the glare of the bright background quasars, we directly measure the rest-frame FUV flux from DLAs and their neighbouring galaxies. At the position of the absorbing gas, we place stringent constraints on the unobscured star formation rates (SFRs) of DLAs to 2-sigma limits of <0.09-0.27 M/yr, corresponding to SFR surface densities <10^(-2.6)-10^(-1.5) M/yr/kpc^2. The implications of these limits for the star formation law, metal enrichment, and cooling rates of DLAs are examined. By studying the distribution of impact parameters as a function of SFRs for all the galaxies detected around these DLAs, we place new direct constraints on the bright end of the UV luminosity function of DLA hosts. We find that <13% of the hosts have SFR>2 M/yr at impact parameters b < (SFR/(M/yr))^(0.8)+6 kpc, differently from current samples of confirmed DLA galaxies. Our observations also disfavor a scenario in which the majority of DLAs arise from bright LBGs at distances 20 < b < 100 kpc. These new findings corroborate a picture in which DLAs do not originate from highly star forming systems that are coincident with the absorbers, and instead suggest that DLAs are associated with faint, possibly isolated, star-forming galaxies. Potential shortcomings of this scenario and future strategies for further investigation are discussed.

description: We re-examine the fraction of low-redshift Sloan Digital Sky Survey satellites and centrals in which star formation has been quenched, using the environment quenching efficiency formalism that separates out the dependence of stellar mass. We show that the centrals of the groups containing the satellites are responding to the environment in the same way as their satellites (at least for stellar masses above 10^10.3 Msun), and that the well-known differences between satellites and the general set of centrals arise because the latter are overwhelmingly dominated by isolated galaxies. The widespread concept of "satellite quenching" as the cause of environmental effects in the galaxy population can therefore be generalized to "group quenching". We then explore the dependence of the quenching efficiency of satellites on overdensity, group-centric distance, halo mass, the stellar mass of the satellite, and the stellar mass and specific star formation rate (sSFR) of its central, trying to isolate the effect of these often interdependent variables. We emphasize the importance of the central sSFR in the quenching efficiency of the associated satellites, and develop the meaning of this "galactic conformity" effect in a probabilistic description of the quenching of galaxies. We show that conformity is strong, and that it varies strongly across parameter space. Several arguments then suggest that environmental quenching and mass quenching may be different manifestations of the same underlying process. The marked difference in the apparent mass dependencies of environment quenching and mass quenching which produces distinctive signatures in the mass functions of centrals and satellites will arise naturally, since, for satellites at least, the distributions of the environmental variables that we investigate in this work are essentially independent of the stellar mass of the satellite.

kite power

description: Most airborne wind energy systems use a single tether to connect the kite with the ground station. Some concepts use an additional bridle line system to transmit the aerodynamic force from the wing to the tether. The use of a bridle line system is particularly important for inflatable membrane kites, which is often complemented by a robotic control unit that is suspended below the wing and used for steering and changing the angle of attack of the wing. When flying sharp turning maneuvers during wind energy harvesting, kites with such a control unit can exhibit a characteristic pitch and roll swinging motion. This thesis investigates the effect of this motion on the steering behavior of the kite and its performance. The work uses flight test data of an implemented airborne wind energy system and several mechanistic models to identify the aerodynamic properties, steering behavior and performance of the kite.

description: Eco-friendly and sustainable synthesis of copper nanoparticles (CuNPs) using the aqueous leaf extract of Manilkara zapota L. and its application as a colorimetric sensor for detection of Fe(II) and Fe(III) ions is reported in this work. At first, the influence of key parameters on the formation of nanoparticles has been investigated. The optimal conditions were determined to be: pH = 11.0, the quantity of the leaf extract = 10.0 mL, copper precursor concentration = 0.5 mM, Temprature = 60 ℃, and incubation time = 30 min. The as-prepared CuNPs were characterised by various analytical techniques such as UV-Vis, TEM, XRD, XPS, and FTIR. The synthesised nanoparticles are amorphous in nature, spherical in shape with a size between 22 to 45 nm. Furthermore, the antioxidant potential of synthesised CuNPs was evaluated using Ferric-Reducing Antioxidant Power (FRAP) assay. Finally, a colorimetric method was described for the determination of Fe(II) and Fe(III) with high sensitivity and selectivity based on the CuNPs which leads to the red-shift of the absorption. Under the optimised conditions, the presented sensor showed a linear relationship over a concentration range of 10.0 μM to 270.0 μM with a LOD of 3.3 μM for both iron ions. Hence, this study has shown a great potential for the development of a cost-effective and selective colorimetric sensor utilising phytogenic CuNPs in the determination of iron ions using UV-Vis spectroscopy.

description: The water quality represents the water’s physical, chemical and biological properties and depends on the environment, and anthropogenic influences. Recently, river water in Dehradun has subjected to immense pressure due to contamination from indecorous land use and urbanisation. In this study area, water quality assessment is carried out with the help of in situ observations and satellite surface reflectance from October 2018 to March 2019. Physicochemical and microbial qualities, namely, ambient temperature (AT), electrical conductivity (EC), water temperature (WT), potential hydrogen (pH), free carbon di oxide (CO2), biological oxygen demand (BOD), dissolved oxygen (DO), total dissolved solids (TDS), salinity (S), total Hardness (TH), calcium hardness (CH), magnesium hardness (MgH), sodium ion (Na), Potassium ion (K), nitrate (NO2), phosphate (PO4), and coliform concentrations (CC) were evaluated in the laboratory, plotted spatially in GIS environment and validated with the Indian Standards (IS). Furthermore, the Pearson correlation matrix was an established between the mean surface reflectance band values of Landsat-8 in the Google Earth Engine (GEE) and the water quality parameters are collected at each station location. The entire river water has been found an unsuitable for drinking but suitable for irrigation purposes. In future, such studies would be supportive for more effective management strategies to overcome the problems of water pollution.

description: Embedding image features into a binary Hamming space can improve both the speed and accuracy of large-scale query-by-example image retrieval systems. Supervised hashing aims to map the original features to compact binary codes in a manner which preserves the label-based similarities of the original data. Most existing approaches apply a single form of hash function, and an optimization process which is typically deeply coupled to this specific form. This tight coupling restricts the flexibility of those methods, and can result in complex optimization problems that are difficult to solve. In this work we proffer a flexible yet simple framework that is able to accommodate different types of loss functions and hash functions. The proposed framework allows a number of existing approaches to hashing to be placed in context, and simplifies the development of new problem-specific hashing methods. Our framework decomposes the into two steps: binary code (hash bits) learning, and hash function learning. The first step can typically be formulated as a binary quadratic problem, and the second step can be accomplished by training standard binary classifiers. For solving large-scale binary code inference, we show how to ensure that the binary quadratic problems are submodular such that an efficient graph cut approach can be used. To achieve efficiency as well as efficacy on large-scale high-dimensional data, we propose to use boosted decision trees as the hash functions, which are nonlinear, highly descriptive, and very fast to train and evaluate. Experiments demonstrate that our proposed method significantly outperforms most state-of-the-art methods, especially on high-dimensional data.

description: This work reports the synthesis of semiconductor selenium nanoparticles/micro-rods (Se-NP/MRs) using the bio-fabrication approach and studies its photocatalytic activity under natural sunlight irradiation. Cabbage leaf extract was used as a reducing agent to fabricate Se-NP/MRs. X-ray diffraction patterns shown the crystalline structure with a crystallite size of 28.17 nm, conferring to planes of hexagonal structure. A characteristic sharp resonance peak in Raman spectra at 235 cm−1 endorsed to the Se – Se bond of crystalline Se-NP/MRs. The prominent peak in the FTIR spectra at 621 cm−1 supported the formation of Se-NP/MRs. Scanning electron micrograph revealed a nearly spherical shape with irregular layers in the 35‒95 nm size range. In contrast, the dimension of the micro-rods was observed to be ~ 10 µm in length and 2.5 µm in diameter. The bandgap energy of Se-NP/MRs was analysed to be 2.14 eV using the Tauc plot. The exciting photocatalytic performance of the bio-fabricated Se-NP/MRs revealed that the methylene blue degradation was ~ 86% in 40 min and ~ 97% in 140 min. Kinetic analysis shows that the pseudo-second-order correlation coefficient is well fitted compared to the pseudo-first-order. Therefore, this work opens the door to further exploration of nano-materials/composites with mixed nanoparticles/micro-rods morphology for sustainable applications in the removal of various textile and industrial contaminants.

description: In this study, we report the adsorption process of Congo Red (CR) dye by calcined Layered Double Hydroxide (ZAC) at 550°C. The urea hydrolysis method was applied to produce highly crystalline Zn2Al-LDH. Samples characterisation was carried out by X-ray diffraction (XRD), Thermogravimetric/differential thermal analysis (TG/DTA), and Fourier transform infrared spectroscopy (FTIR). The results show that the adsorption of CR on calcined ZnAl-LDH was accompanied by the reconstruction of the layered structure. The ZAC showed higher adsorption efficiency versus other adsorbent under investigation and optimum conditions of contact time, adsorbent dose, pH and temperature were found to be 50 min, 0.02 g, 7 and 318 K, respectively. Isotherm studies show that the Langmuir isotherm model was appropriate to describe the CR adsorption data compared with Freundlich and Temkin isotherm models, with a higher correlation coefficient (R2 > 0.99) and maximum adsorption capacity of 406.5 mg/g. The thermodynamic parameters revealed that the adsorption process was spontaneous, endothermic, and governed by chemisorption. To further facilitate the recovery process in CR adsorption, we test the feasibility of applying ZnAl-LDH and its calcined product at 550°C entrapped in alginate beads. Experimental results indicate that alginate-coated ZAC beads, which exhibited remarkable adsorption performance, were more stable and require less effort to pull and separate than the alginate/ZnAl-LDH composite beads.

description: We study the effect of laser photon merging, or equivalently high harmonic generation, in the quantum vacuum subject to inhomogeneous electromagnetic fields. Such a process is facilitated by the effective nonlinear couplings arising from charged particle-antiparticle fluctuations in the quantum vacuum subject to strong electromagnetic fields. We derive explicit results for general kinematic and polarization configurations involving optical photons. Concentrating on merged photons in reflected channels which are preferable in experiments for reasons of noise suppression, we demonstrate that photon merging is typically dominated by the competing nonlinear process of quantum reflection, though appropriate polarization and signal filtering could specifically search for the merging process. As a byproduct, we devise a novel systematic expansion of the photon polarization tensor in plane wave fields.

description: Transcription factors perform facilitated diffusion (3D diffusion in the cytosol and 1D diffusion on the DNA) when binding to their target sites to regulate gene expression. Here, we investigated the influence of this binding mechanism on the noise in gene expression. Our results showed that, for biologically relevant parameters, the binding process can be represented by a two-state Markov model and that the accelerated target finding due to facilitated diffusion leads to a reduction in both the mRNA and the protein noise.

description: NiCr-LDH/BiOCl and NiCr-LDH/TiO2 nanocomposites were successfully synthesised by co-precipitation and hydrothermal methods. Their structure, morphology and optical properties were analysed by XRD, SEM, UV−vis, XPS and FTIR techniques. The Rhodamine B (RhB) dye was used as a model pollutant to evaluate the catalytic activity for the nanocomposites under sunlight irradiation for 60 min. The results showed a significant enhancement in the photocatalytic activity of NiCr-LDH/BiOCl (up to 96.57%), higher than that of NiCr-LDH/TiO2 (89.58%), and pure phase NiCr-LDH (26.09%). The nanocomposites exhibited a high catalytic performance than TiO2 and BiOCl pure phases. This funding was not related to the Bi or Ti content but to the dispersion of the pure phase on the surface of the NiCr-LDH. The enhanced photocatalytic activity of the NiCr-LDH/BiOCl naocomposite mainly attributed to the formation of heterojunction between LDH and BiOCl for efficient separation of photoinduced electrons and holes. Hydroxyl radicals and holes were the main active species. Both NiCr-LDH/BiOCl and NiCr-LDH/TiO2 photocatalysts exhibited high stability and reusability even after four cycles. Based on the experimental results, a possible photocatalytic mechanism on both nanocomposites was proposed.

description: Из-за постоянного роста числа космических аппаратов (КА) непрерывно растёт количество космического мусора (КМ) в околоземном пространстве. Движущиеся на высоких скоростях частицы метеороидов и техногенных обломков представляют серьёзную угрозу для летательных аппаратов, находящихся на околоземных орбитах. Уникальное по своей конструкции и габаритам общепланетарное транспортное средство (ОТС) планируется эксплуатировать на орбите продолжительное время, из-за чего возрастает вероятность его столкновения с различным КМ. Для безопасного функционирования ОТС необходимо обеспечить надёжную защиту его оболочки от КМ. В данной статье выполнен анализ космических объектов, создающих опасность для ОТС на рабочей орбите. Показаны типичные размеры и скорости частиц КМ. Предложены варианты защитных конструкций ОТС в зависимости от степени критичности последствий встречи с метеороидами. На основании предельных баллистических уравнений подобраны параметры защиты от КМ размером 2 мм. Для определения стойкости корпуса ОТС при соударении с частицами КМ размером 5 мм проведено численное моделирование баллистических испытаний в пакете конечно-элементного анализа LS-DYNA с использованием метода сглаженных частиц. Для описания поведения материалов применялись модели Джонсона – Кука и Купера – Саймондса. Верификация моделей и подходов выполнена при помощи сравнения результатов моделирования с представленными в открытых источниках данными натурных испытаний пробития фрагмента стенки бака спутника «Спектр-УФ».

description: An on-line flow injection mercury analyser (FIMA) for inorganic mercury (Hg) analysis in environmental waters is presented. The FIMA is a portable dual-channel and purge-and-trap system combining aqueous reduction with stannous chloride (SnCl2), two-stage gold (Au) amalgamation, thermal desorption of Hg0 and final detection with cold vapour atomic fluorescence spectrometry (CVAFS). Simultaneous on-line operations of sample loading and analysis make analytical throughput and accuracy improved and contamination eliminated. Results of system optimisation and reliability regarding the determination of inorganic Hg2+ are described. Analytical performances of both channels were the same in terms of data reliability. Low procedural blanks were obtained from laboratory and field trip (≤5 pg, n = 30). Excellent calibrations (r2 > 0.99) with a high precision and good stability (RSD <5%, n = 30) were obtained. Detection limits and reproducibility of the methods have been estimated as ≤0.05 ng L−1 and <5% (0.5 ng L−1, n = 30). The system was finally validated by measurements comparison of the two channels (r2 > 0.98), and analysis of a certified reference material (coastal seawater BCR-579, recoveries 101 ± 4%, n = 10). Overall, a sample throughput of ~10 samples per hour with two-channel detections of FIMA can be achieved. The onboard analysis of inorganic Hg species (e.g. elemental, reactive, and total Hg) in surface seawaters of the East China Sea (ECS) are also successfully achieved. The portable FIMA is fast, easy, and robust for reliable monitoring of Hg in natural seawaters.
