description: A detailed understanding of the population and coherence dynamics in optically driven individual emitters in solids and their signatures in ultrafast nonlinear-optical signals is of prime importance for their applications in future quantum and optical technologies. In a combined experimental and theoretical study on exciton complexes in single semiconductor quantum dots we reveal a detailed picture of the dynamics employing three-beam polarization-resolved four-wave mixing (FWM) micro-spectroscopy. The oscillatory dynamics of the FWM signals in the exciton-biexciton system is governed by the fine-structure splitting and the biexciton binding energy in an excellent quantitative agreement between measurement and analytical description. The analysis of the excitation conditions exhibits a dependence of the dynamics on the specific choice of polarization configuration, pulse areas and temporal ordering of driving fields. The interplay between the transitions in the four-level exciton system leads to rich evolution of coherence and population. Using two-dimensional FWM spectroscopy we elucidate the exciton-biexciton coupling and identify neutral and charged exciton complexes in a single quantum dot. Our investigations thus clearly reveal that FWM spectroscopy is a powerful tool to characterize spectral and dynamical properties of single quantum structures.

description: This study proposes a marine biomass utilization system and describes an anaerobic digestion system using marine biomass and food waste. Three scenarios are presented where the biomass amount varies and is sourced from different suppliers. Exergy is used for the feasibility evaluation. Various kinds of material and energy overall system are described in terms of exergy; exergy production and consumption is identified. The exergy efficiency of the overall system is introduced. It is found that exergy production is bigger than exergy consumption and that the exergy of organic substances accounts for most of the exergy produced in all cases. This study provides a holistic viewpoint using exergy for the feasibility evaluation.

description: This volume contains the papers selected among those which were presented at the 3rd International Workshop on Verification and Program Transformation (VPT 2015) held in London, UK, on April 11th, 2015. Previous editions of the Workshop were held at Saint-Petersburg (Russia) in 2013, and Vienna (Austria) in 2014. Those papers show that methods and tools developed in the field of program transformation such as partial evaluation and fold/unfold transformations, and supercompilation, can be applied in the verification of software systems. They also show how some program verification methods, such as model checking techniques, abstract interpretation, SAT and SMT solving, and automated theorem proving, can be used to enhance program transformation techniques, thereby making these techniques more powerful and useful in practice.

description: The experimental study of neural networks requires simultaneous measurements of a massive number of neurons, while monitoring properties of the connectivity, synaptic strengths and delays. Current technological barriers make such a mission unachievable. In addition, as a result of the enormous number of required measurements, the estimated network parameters would differ from the original ones. Here we present a versatile experimental technique, which enables the study of recurrent neural networks activity while being capable of dictating the network connectivity and synaptic strengths. This method is based on the observation that the response of neurons depends solely on their recent stimulations, a short-term memory. It allows a long-term scheme of stimulation and recording of a single neuron, to mimic simultaneous activity measurements of neurons in a recurrent network. Utilization of this technique demonstrates the spontaneous emergence of cooperative synchronous oscillations, in particular the coexistence of fast Gamma and slow Delta oscillations, and opens the horizon for the experimental study of other cooperative phenomena within large-scale neural networks.

description: The transition of the energy system from fossil to renewable sources is fostered in different regions of the world. Biomethane, as a substitute for natural gas, is one way to increase fuel independence by using local resources and reduce the environmental impact. This paper gives an overview of the possible application of biomethane in Europe (with focus on the EU) and China and discusses the relevance of coherent frame condition for market development. Both regions, Europe and China, have huge biomass respective biomethane potential and started already to implement a biomethane market, whereas the one in the EU is already well advanced. At the end of this study a recommendation for both areas for a stable and sustainable biomethane development is given.

description: Coupled atom-cavity arrays, such as those described by the Jaynes-Cummings Hubbard model, have the potential to emulate a wide range of condensed matter phenomena. In particular, the strongly correlated states of the fractional quantum Hall effect can be realised. At some filling fractions, the fraction quantum Hall effect has been shown to possess ground states with non-abelian excitations. The most well studied of these states is the Pfaffian state of Moore and Read, which is the groundstate of a Hall Liquid with a 3-body interaction. In this paper we show how an effective 3-body interaction can be generated within the Cavity QED framework, and that a Pfaffian-like groundstate of these systems exists.

description: We report for the first time the application of HS-SPME-GC coupled with sulfur-specific pulsed flame photometric detection to sensitively analyze the volatile sulfur compounds (VSC’s) present in drum roasted malt and barley samples typically used in brewing. Twenty-five VSC’s were identified across a range of 9 roasted products produced from barley/malt. Thiophenes (n = 10) were a major class of heterocyclic sulfur compounds identified, along with thiazoles (n = 4), and thiofurans (n = 2). Quantitative (n = 18) and semi-quantitative (n = 6) data are reported for VSC’s across this product range. Principal Component Analysis (PCA) of data clearly identified (PC1) that heterocyclic sulfur compounds were formed in products processed at high temperatures (>170 °C) under dry conditions (roasted barley, chocolate and black malts). Whereas compounds such as methyl dithiolane and methyl propyl sulfide were associated primarily with lower temperature finished products (crystal, amber and cara malts). Pathways for the generation of observed VSC’s are considered alongside typical roasting conditions employed in the manufacture of these products. Concentrations of VSC’s identified will certainly contribute characteristic aromas to the roasted products themselves. The transfer of VSC’s from the grist into finished beer, and their sensory impact in a range of beer styles, remains to be determined.

description: Motivated by alleviating CO$_2$ pollution, Electric Vehicle (EV) based applications have recently received wide interests from both commercial and research communities by using electric energy instead of traditional fuel energy. Although EVs are inherently with limited travelling distance, such limitation could be overcome by deploying public Charging Stations (CSs) to recharge EVs battery during their journeys. In this paper we propose a novel communication framework for on-the-move EV charging scenario, based on the Publish/Subscribe (P/S) mechanism for disseminating necessary CS information to EVs, in order for them to make optimized decisions on where to charge. A core part of our communication framework is the utilization of Road Side Units (RSUs) to bridge the information flow from CSs to EVs, which has been regarded as a type of cost-efficient communication infrastructure. Under this design, we introduce two complementary communication modes of signalling protocols, namely Push and Pull Modes, in order to enable the required information dissemination operation. Both analysis and simulation show the advantage of Pull Mode, in which the information is cached at RSUs to support asynchronous communication. We further propose a remote reservation service based on the Pull Mode, such that the CS-selection decision making can utilize the knowledge of EVs' charging reservation, as published from EVs through RSUs to CSs. Results show that both the performance at CS and EV sides are further improved based on using this anticipated information.

description: We present the first images of four debris disks observed in scattered light around the young (4--250 Myr old) M dwarfs TWA 7 and TWA 25, the K6 star HD 35650, and the G2 star HD 377. We obtained these images by reprocessing archival Hubble Space Telescope NICMOS coronagraph data with modern post-processing techniques as part of the Archival Legacy Investigation of Circumstellar Environments (ALICE) program. All four disks appear faint and compact compared with other debris disks resolved in scattered light. The disks around TWA 25, HD 35650, and HD 377 appear very inclined, while TWA 7's disk is viewed nearly face-on. The surface brightness of HD 35650's disk is strongly asymmetric. These new detections raise the number of disks resolved in scattered light around M and late-K stars from one (the AU Mic system) to four. This new sample of resolved disks enables comparative studies of heretofore scarce debris disks around low-mass stars relative to solar-type stars.

Combining theory, simulation, and experiments we demonstrate a new scenario of first-order phase transitions that occurs via a complete inversion of the energy landscape, featuring non-conventional properties that allow for: (i) tuning of crystal symmetry; (ii) control of dynamical properties of different crystalline orders via tuning of their relative stability with an external magnetic field; (iii) an equivalent but independent control of the same dynamic properties via temporal modulations of that field; and (iv) non-standard phase-ordering kinetics involving spontaneous formation of transient metastable domains.

Three-dimensional simulations of long duration gamma-ray burst jets: time scales from variable engines

description: Gamma-ray burst light curves are characterized by marked variability, each showing unique properties. The origin of such variability, at least for a fraction of long GRBs, may be the result of an unsteady central engine. It is thus important to study the effects that an episodic central engine has on the jet propagation and, eventually, on the prompt emission within the collapsar scenario. Thus, in this study we follow the interaction of pulsed outflows with their progenitor stars with hydrodynamic numerical simulations in both two and three dimensions. We show that the propagation of unsteady jets is affected by the interaction with the progenitor material well after the break-out time, especially for jets with long quiescent times, comparable to or larger than a second. We also show that this interaction can lead to an asymmetric behavior in which pulse durations and quiescent periods are systematically different. After the pulsed jets drill through the progenitor and the interstellar medium, we find that, on average, the quiescent epochs last longer than the pulses (even in simulations with symmetrical active and quiescent engine times). This could explain the asymmetry detected in the light curves of long-quiescent times duration gamma-ray bursts.

description: The classic method for mass determination in a SUSY-like cascade decay chain relies on measurements of the kinematic endpoints in the invariant mass distributions of suitable collections of visible decay products. However, the procedure is complicated by combinatorial ambiguities: e.g., the visible final state particles may be indistinguishable (as in the case of QCD jets), or one may not know the exact order in which they are emitted along the decay chain. In order to avoid such combinatorial ambiguities, we propose to treat the final state particles fully democratically and consider the sorted set of the invariant masses of all possible partitions of the visible particles in the decay chain. In particular, for a decay to N visible particles, one considers the sorted sets of all possible n-body invariant mass combinations (2 <= n <= N) and determines the kinematic endpoint m_(n,r)^max of the distribution of the r-th largest n-body invariant mass m_(n,r) for each possible value of n and r. For the classic example of a squark decay in supersymmetry, we provide analytical formulas for the interpretation of these endpoints in terms of the underlying physical masses. We point out that these measurements can be used to determine the structure of the decay topology, e.g., the number and position of intermediate on-shell resonances.

description: The main flavor metabolites and sensory profiles of six craft beers and ten industrial beers available in the Chinese market were studied. The common sensory profiles of the six craft beers included head retention, hydrogen sulfide, oxidation, body, bitterness, malty, bruised apple, yeasty, diacetyl, caramelized, and cheesy. The main flavor metabolites related to these common sensory profiles in the craft beers were isoamyl acetate, medium chain fatty acids (MCFA) ethyl esters (ethyl hexanoate), and diacetyl. The common sensory profiles of the ten industrial beer samples included estery, cooked vegetable, and solvent flavors. The foam stability of the craft beers was higher than that of the industrial beers, showing a significant difference (P < 0.05). The main differential flavor metabolites between the craft beers and industrial beers were ethyl hexanoate, ethanol, and isobutyl alcohol. The content of ethyl hexanoate in the craft beers was significantly higher than that in the industrial beers (P < 0.05), while the content of ethanol and isobutyl alcohol in the craft beers was significantly lower than in the industrial beers (P < 0.05). This study provides a preliminary look at the two groups of beers; however, since it was a small sample, more samples will have to be analyzed in the future to draw definitive conclusions outside of this particular selected sampling. However, the study does provide a useful framework for future research in this area. Supplemental data for this article is available online at https://doi.org/10.1080/03610470.2021.1980677.

description: The advent of devices based on single dopants, such as the single atom transistor, the single spin magnetometer and the single atom memory, motivates the quest for strategies that permit to control matter with atomic precision. Manipulation of individual atoms by means of low-temperature scanning tunnelling microscopy provides ways to store data in atoms, encoded either into their charge state, magnetization state or lattice position. A defining challenge at this stage is the controlled integration of these individual functional atoms into extended, scalable atomic circuits. Here we present a robust digital atomic scale memory of up to 1 kilobyte (8,000 bits) using an array of individual surface vacancies in a chlorine terminated Cu(100) surface. The memory can be read and rewritten automatically by means of atomic scale markers, and offers an areal density of 502 Terabits per square inch, outperforming state-of-the-art hard disk drives by three orders of magnitude. Furthermore, the chlorine vacancies are found to be stable at temperatures up to 77 K, offering prospects for expanding large-scale atomic assembly towards ambient conditions.

description: Cysteinylated and glutathionylated precursors of sulfanylalkyl alcohols have been extensively studied in hop and grape matrices, in contrast to those of sulfanylalkyl aldehydes and sulfanylalkyl acetates. Here, cysteinylated and glutathionylated adducts of 3-sulfanylpentanal (Cys-3SPal and G-3SPal), 3-sulfanylhexanal (Cys-3SHal and G-3SHal), 3-sulfanylpentyl acetate (only Cys-3SPA), and 3-sulfanylhexyl acetate (Cys-3SHA and G-3SHA) were first synthesized. Next, the occurrence of these compounds was studied by RP-HPLC-ESI(+)-MRM and apotryptophanase-GC-PFPD in a few dual hops and Belgian grape must samples. None of the Cys-adducts of 3-sulfanylalkyl aldehydes were detected in hop or grape extracts, while G-3SPal was identified for the first time in a natural matrix. Concentrations ranging from 3 to 15 mg/kg were found in several hop varieties, including Citra, Mandarina Bavaria, Mosaic, Nelson Sauvin, Polaris, and Saaz, whereas G-3SHal was detected (below the quantitation limit) only in the four latters. As for esters, Cys-3SPA was found in hop (4 mg/kg in Mosaic), while G-3SHA was detected only in grape extracts (Belgian Chardonnay and Johanniter). Besides the ubiquitous G-3SHol, G-3SPol was identified here for the first time in grape must (up to 7 mg/kg in Johanniter).
title: Effects of the Polymer Amount and pH on Proton Transport in Mesopores

description: Proton exchange membranes (PEMs) have various applications, such as in electrolysis technology for hydrogen generation, vanadium flow batteries for energy storage, and fuel cells for energy conversion. To increase PEM performance and expand the range of PEM applications, the underlying transport mechanisms of PEMs need to be understood. Mesoporous silica thin films are versatile model materials for proton transport investigation and are prepared with a pore size of ≈12 nm and film thickness of ≈565 nm by evaporation‐induced self‐assembly, providing an ordered, mesoporous, rigid matrix that allows us to deduce the structure‐property relationship with respect to proton conductivity. Different amounts of sulfonic acid‐bearing groups are introduced into the mesopores using the grafting‐through polymerization of sulfopropylmethacrylate. The relationship between proton transport and the pH of the surrounding solution in poly‐sulfopropylmethacrylate‐functionalized mesopores is investigated using electrochemical impedance spectroscopy. The proton conductivity is found to depend on both the proton concentration in solution and the number of proton transporting groups inside the pore, indicating the major role of charge regulation and the confinement effect on proton transport.

description: We derive augmented quasiclassical equations of superconductivity with the Lorentz force in the Matsubara formalism so that the charge redistribution due to supercurrent can be calculated quantitatively. Using it, we obtain an analytic expression for the vortex-core charge of an isolated vortex in extreme type-II materials given in terms of the London penetration depth and the equilibrium Hall coefficient. It depends strongly on the Fermi surface curvature and gap anisotropy, and may change sign even as a function of temperature due to the variation in the excitation curvature under the growing energy gap. This is also confirmed in our numerical study of high-$T_{\rm c}$ superconductors.

description: We developed an aerosol charger that incorporated commercial ionizers to make the setup simple and easily replicated. The built-in high-voltage source for inducing corona discharge embedded in the developed charger (MHM charger) was modulated with pulses so the production of positive and negative ions could be independently regulated. We have studied several attempts to evaluate the performance of the MHM charger as a bipolar charger for charging ultrafine particles. We found that by adjusting the duty-cycle of the modulated pulses, positive and negative ion production is manageable, and the ion concentration depends on the flow rate of the intake air. We used a mini-cyDMA to measure the mobility distribution of positive and negative ions with an average of 1.09 and 1.67 cm2 V−1 s−1, respectively. By utilizing initially charged and neutral particles, we obtained the penetration ratio of both particles: 0.75 and 0.774, respectively. The issue of the MHM charger to generate new particles was also investigated. We found that, on average, the produced new particle concentration was only 5.2 cm−3. In this study, we evaluated the performance of the MHM charger to charge particles by measuring the neutral fraction and charging efficiency. The neutral fraction with particle loss correction follows the established model. The intrinsic and extrinsic charging efficiencies at 100 nm were up to 19% and 41%, respectively. We also assessed the application of the MHM charger in the monodisperse particle generator system. The results showed that the MHM charger could be utilized as an alternative aerosol charger.

description: A deep-space exploration mission with low-thrust propulsion to rendezvous with multiple asteroids is investigated. Indirect methods, based on the optimal control theory, are implemented to optimize the fuel consumption. The application of indirect methods for optimizing low-thrust trajectories between two asteroids is briefly given. An effective method is proposed to provide initial guesses for transfers between close near-circular near-coplanar orbits. The conditions for optimality of a multi-asteroid rendezvous mission are determined. The intuitive method of splitting the trajectories into several legs that are solved sequentially is applied first. Then the results are patched together by a scaling method to provide a tentative guess for optimizing the whole trajectory. Numerical examples of optimizing three probe exploration sequences that contain a dozen asteroids each demonstrate the validity and efficiency of these methods.

A number field extension of a question of Milnor

description: Milnor formulated a conjecture about rational linear independence of some special Hurwitz zeta values. The second and third authors along with Ram Murty studied this conjecture and suggested an extension of Milnor's conjecture. In this note, we investigate the number field generalisation of this extended Milnor conjecture. We indicate the motivation for considering this number field case by noting that such a phenomenon is true in an analogous context. We also study some new spaces related to normalised Hurwitz zeta values.
Linewidths in excitonic absorption spectra of cuprous oxide

description: We present a theoretical calculation of the absorption spectrum of cuprous oxide $\left(\mathrm{Cu_{2}O}\right)$ based on the general theory developed by Y. Toyozawa. An inclusion not only of acoustic phonons but also of optical phonons and of specific properties of the excitons in $\mathrm{Cu_{2}O}$ like the central-cell corrections for the $1S$-exciton allows us to calculate the experimentally observed line widths in experiments by T. Kazimierczuk et al [Nature 514, 343, (2014)] within the same order of magnitude, which demonstrates a clear improvement in comparison to earlier work on this topic. We also discuss a variety of further effects, which explain the still observable discrepancy between theory and experiment but can hardly be included in theoretical calculations.

description: This paper is a new step in the project of systematic description of colored knot polynomials started in arXiv:1506.00339. In this paper, we managed to explicitly find the inclusive Racah matrix, i.e. the whole set of mixing matrices in channels R^3->Q with all possible Q, for R=[3,1]. The calculation is made possible by the use of a newly-developed efficient highest-weight method, still it remains tedious. The result allows one to evaluate and investigate [3,1]-colored polynomials for arbitrary 3-strand knots, and this confirms many previous conjectures on various factorizations, universality, and differential expansions. We consider in some detail the next-to-twist-knots three-strand family (n,-1|1,-1) and deduce its colored HOMFLY. Also confirmed and clarified is the eigenvalue hypothesis for the Racah matrices, which promises to provide a shortcut to generic formulas for arbitrary representations.

description: The influence of aerosol concentration on the charge per particle is investigated in post-DC corona diffusion chargers for particle diameter between 10 nm and 1 µm. Particles are charged as they pass through the charger volume by collection of ions; the ion concentration decreases along the same path due to unipolar space charge repulsion and collection on walls. With crossflow of ions and aerosols, the final mean charge per particle decreases by up to one order of magnitude with increasing aerosol concentration from 109 to 1011 m−3. The evolution of the ion density profile along particle trajectories with aerosol concentration is shown to be due to the consumption of ions by aerosol charging and to ion dispersion by unipolar space charge repulsion including ions and charged particles. Both are investigated using a simplified 1.5 D model with axial symmetry and homogeneous mixing of ions and aerosols. It is shown that, for a given operating condition, the aerosol space charge is responsible for the modification of the spatial ion distribution and the related lower Ni × τ and charge per particle reported at higher aerosol concentration. From calculations, we define the maximal aerosol concentration to keep the mean charge per particle unaffected by aerosol space charge in the optimal case of homogeneous mixing of ion and aerosol. Finally, the comparison of different ion-aerosol mixing conditions highlights that an axial symmetry of the charger reduces the influence of aerosol space charge. This effect of aerosol concentration on the particle charge is critical for aerosol chargers devoted to electric mobility selection for size measurements or focused electro-deposition, as well as for concentration measurements as performed using emerging low cost sensors based on corona chargers.

description: In recent years, a growing number of studies investigated the presence of micro- and nanoscopic particles in the environment originating from commonly used plastics. Pathways into the environment and generation mechanisms are still not well understood. Controlled generation methods of particles from macroplastics are required to enable research of the fundamental processes governing the dispersion of these particles in the environment. Here, we present the results of a study focusing on the generation and characterization of aerosol nanoparticles from macroplastics using a tube furnace. Three common thermoplastics were used as particle material: Polyethene (PE), Polypropene (PP) and Polyethylene Terephthalate (PET). Commodity versions of these materials were compared to higher-purity versions. The produced particles were size characterized using a Differential Mobility Particle Sizer. Furthermore, we investigated the activation of particles from PET in Condensation Particle Counters by measuring the 50% cutoff diameters. The results could be directly compared to previous measurements using other organic seed particles. Our study provides crucial insights into the effects governing the production of aerosolized nanoparticles from thermoplastics at comparatively low temperatures. We therefore expect our study to act as basis for further research toward a thorough understanding of the physicochemical processes governing nanoparticle production from plastic materials. Eventually this may lead to new detection methods of nanoplastics in airborne state and allow for quantification of airborne nanoplastic concentrations.
