description: The possibility to manipulate the wavepackets of single photons or biphotons has enriched quantum optics and quantum information science, with examples ranging from faithful quantum-state mapping and high-efficiency quantum memory to the purification of single photons. Here we demonstrate another fascinating use of wavepacket manipulation on restoring quantum interference. By modulating the photons' temporal wavepacket, we observe the revival of post-selected entanglement that would otherwise be degraded or lost due to poor quantum interference. Our study shows that the amount of the restored entanglement is only limited by the forms of modulation and can achieve full recovery if the modulation function is properly designed. Our work has potential applications in long-distance quantum communication and linear optical quantum computation, particularly for quantum repeaters and large cluster states.

description: Sustainable intensification is considered a key strategy to harmonize economic and environmental goals in rice-wheat cropping system in the developing countries. This strategy encourages farmers to grow spring season crops in the land remaining fallows after harvesting wheat. This paper explores the impact of climatic, demographic, economic and institutional variables on area under spring season crops. Data for the study were collected from 640 households spreading across the eight Tarai districts of Nepal in 2010. The major crops grown in the spring season are mungbean, maize and rice, and farmers allocate difference amount of their land for these crops. So, three crops specific regressions were modeled through Tobit regression with the assumption that households’ allocate their lands considering the potential benefit they get from these crops during the spring reason. Result shows that rainfall has positive impact on maize and rice; whereas, it is negative on mungbean. Similarly, this study reveals that male-headed households allocate larger amount of their lands for each of these crops than female-headed households. This is due to better access of fertilizers and training to male-headed households. Moreover, higher operational holders allocate more land for the spring season crops as compared to their counterparts.

description: We discuss the localization behavior of localized electronic wave functions in the one- and two-dimensional tight-binding Anderson model with diagonal disorder. We find that the distributions of the local wave function amplitudes at fixed distances from the localization center are well approximated by log-normal fits which become exact at large distances. These fits are consistent with the standard single parameter scaling theory for the Anderson model in 1d, but they suggest that a second parameter is required to describe the scaling behavior of the amplitude fluctuations in 2d. From the log-normal distributions we calculate analytically the decay of the mean wave functions. For short distances from the localization center we find stretched exponential localization ("sublocalization") in both, 1d and 2d. In 1d, for large distances, the mean wave functions depend on the number of configurations N used in the averaging procedure and decay faster that exponentially ("superlocalization") converging to simple exponential behavior only in the asymptotic limit. In 2d, in contrast, the localization length increases logarithmically with the distance from the localization center and sublocalization occurs also in the second regime. The N-dependence of the mean wave functions is weak. The analytical result agrees remarkably well with the numerical calculations.

description: In the recent past the coffee production sector witnessed a rapid expansion of certification programs promoting voluntary sustainability standards, one of which is UTZ Certified. In this article we assess the impact that this program has on participating smallholder farmers by reviewing the results of an agent-based simulation for modeling rural producer organizations. We present the developed empirical simulation model by sharing the common protocol, which documents the structure the applied simulation tool and its parameterization for the group of coffee farmers, and reporting the results of model validation. The main strength of this assessment is that it considers certification-related costs of the farmers, which are ignored in the analyses available so far. The obtained simulation results constitute quantitative evidence of UTZ certification being able to create considerable positive impacts on the participating farmers. The results outline the importance of external financing and supportive measures complementing certification in groups.

description: The transfer of quantum information through a noisy environment is a central challenge in the fields of quantum communication, imaging and nanophotonics. In particular, high-dimensional quantum states of light enable quantum networks with significantly higher information capacities and noise robustness as compared with qubits. However, although qubit entanglement has been distributed over large distances through free space and fibre, the transport of high-dimensional entanglement is hindered by the complexity of the channel, which encompasses effects such as free-space turbulence or mode mixing in multimode waveguides. Here, we demonstrate the transport of six-dimensional spatial-mode entanglement through a 2-m-long, commercial multimode fibre with 84.4% fidelity. We show how the entanglement can itself be used to measure the transmission matrix of the complex medium, allowing the recovery of quantum correlations that were initially lost. Using a unique property of entangled states, the medium is rendered transparent to entanglement by carefully 'scrambling' the photon that did not enter it, rather than unscrambling the photon that did. Our work overcomes a primary challenge in the fields of quantum communication and imaging, and opens a new pathway towards the control of complex scattering processes in the quantum regime.

description: The continuous aging of the EU population challenges the sustainability of welfare states. Part of the solution is to ensure that people not only live longer but also better (i.e., that they can function independently while remaining free of disease/disability), which may be achieved through better nutrition and adoption of healthier lifestyles. We test that proposition with a behavioural model of diet quality choice and health determination. The simultaneous equations model, which accounts for the endogeneity of lifestyle choices and is applied to a sample of older Italians, allows for bi-directional causality between diet and health. The health production function confirms that good quality diets and other healthy lifestyles (e.g., physical activity, smoking and drinking) improve self-assessed health. In turn, the elderly respond to illness by improving their diets and exercising more. Supporting healthy aging may be achieved through targeted policies aimed at promoting healthy eating and other healthy lifestyles.

description: This study reports the synthesis of new zinc and magnesium phthalocyanine compounds with ((ethylenediamine-N,N′,N′-triacetic acid-N-2-ethyl)oxy) (ETAEO) substituted groups. A novel compound, (4-ETAEO) phthalonitrile, for the starting material of these phthalocyanines was synthesized. The exact characterization of the compounds was carried out with 1H NMR, IR, UV-Vis, and mass spectra. Fluorescence intensity of these metallophthalocyanines (MPcs) was investigated at 1 × 10−5 M concentration in tetrahydrofuran (THF). Electronic absorption measurements of the phthalocyanine compounds in the tetrahydrofuran were performed. Photodegradation was performed in dimethylformamide (DMF). Optimized structure, boundary molecular orbitals (HOMO and LUMO), natural bond orbital (NBO) analysis and global reactivity descriptors were analyzed by DFT calculations.

description: We investigate the dimensional crossover from three to two dimensions in an ultracold Fermi gas across the whole BCS-BEC crossover. Of particular interest is the strongly interacting regime as strong correlations are more pronounced in reduced dimensions. Our results are obtained from first principles within the framework of the functional renormalisation group (FRG). Here, the confinement of the transverse direction is imposed by means of periodic boundary conditions. We calculate the equation of state, the gap parameter at zero temperature and the superfluid transition temperature across a wide range of transversal confinement length scales. Particular emphasis is put on the determination of the finite temperature phase diagram for different confinement length scales. In the end, our results are compared with recent experimental observations and we discuss them in the context of other theoretical works.

description: Buildings sector is one of the major consumers of energy in the United States. The buildings HVAC (Heating, Ventilation, and Air Conditioning) systems, whose functionality is to maintain thermal comfort and indoor air quality (IAQ), account for almost half of the energy consumed by the buildings. Thus, intelligent scheduling of the building HVAC system has the potential for tremendous energy and cost savings while ensuring that the control objectives (thermal comfort, air quality) are satisfied. Recently, several works have focused on model-free deep reinforcement learning based techniques such as Deep Q-Network (DQN). Such methods require extensive interactions with the environment. Thus, they are impractical to implement in real systems due to low sample efficiency. Safety-aware exploration is another challenge in real systems since certain actions at particular states may result in catastrophic outcomes. To address these issues and challenges, we propose a model-based reinforcement learning approach that learns the system dynamics using a neural network. Then, we adopt Model Predictive Control (MPC) using the learned system dynamics to perform control with random-sampling shooting method. To ensure safe exploration, we limit the actions within safe range and the maximum absolute change of actions according to prior knowledge. We evaluate our ideas through simulation using widely adopted EnergyPlus tool on a case study consisting of a two zone data-center. Experiments show that the average deviation of the trajectories sampled from the learned dynamics and the ground truth is below $20\%$. Compared with baseline approaches, we reduce the total energy consumption by $17.1\% \sim 21.8\%$. Compared with model-free reinforcement learning approach, we reduce the required number of training steps to converge by 10x.

description: We study analytical solutions of the Fractional Boussinesq Equation (FBE), which is an effective model for the Fermi-Pasta-Ulam (FPU) one-dimensional lattice with long-range couplings. The couplings decay as a power-law with exponent s, with 1 < s < 3, so that the energy density is finite, but s is small enough to observe genuine long-range effects. The analytic solutions are obtained by introducing an ansatz for the dependence of the field on space and time. This allows to reduce the FBE to an ordinary differential equation, which can be explicitly solved. The solutions are initially localized and they delocalize progressively as time evolves. Depending on the value of s the solution is either a pulse (meaning a bump) or an anti-pulse (i.e., a hole) on a constant field for 1 < s < 2 and 2 < s < 3, respectively.

description: We demonstrate an optical unstable phase for a laser driven erbium ion ensemble. The transmitted light through an erbium-doped yttrium orthosillicate crystal becomes dynamically unstable when illuminated by a strong continuous-wave laser. Transient net gain was recorded if the light passes the sample twice. The experimental results are understood in the framework of a many-body system interacting with a classical field, where the ion-ion interaction becomes significant as a result of the high erbium concentration. A Bloch-equation model that includes the excitation-induced frequency-shift is introduced to discuss the conditions of the instabilities.

description: The coherent nonlinear process where a single photon simultaneously excites two or more two-level systems (qubits) in a single-mode resonator has recently been theoretically predicted. Here we explore the case where the two qubits are placed in different resonators in an array of two or three weakly coupled resonators. Investigating different setups and excitation schemes, we show that this process can still occur with a probability approaching one under specific conditions. The obtained results provide interesting insights into subtle causality issues underlying the simultaneous excitation processes of qubits placed in different resonators.

description: We report a novel mechanism for the occurrence of chaos at the macroscopic level induced by the frustration of interaction, namely frustration-induced chaos, in a non-monotonic sequential associative memory model. We succeed in deriving exact macroscopic dynamical equations from the microscopic dynamics in the case of the thermodynamic limit and prove that two order parameters dominate this large-degree-of-freedom system. Two-parameter bifurcation diagrams are obtained from the order-parameter equations. Then we analytically show that the chaos is low-dimensional at the macroscopic level when the system has some degree of frustration, but that the chaos definitely does not occur without the frustration.

description: We have observed the broad-line radio galaxy Arp 102B with ASCA in order to determine the absorbing column density towards its X-ray source and measure its X-ray spectrum. The ultimate goal was to constrain the properties of the medium responsible for the metastable Fe II absorption lines observed in its UV spectrum. The 0.5-10 keV X-ray spectrum is described by a simple power-law model of photon index 1.58+/-0.04 modified by photoelectric absorption with an column density of (2.8+/-0.3)x10^{21} cm^{-2}. An Fe K-alpha line is not detected with an upper limit to its equivalent width of 200 eV (assuming FWHM = 60,000 km/s. Using the above column density the observed S.E.D. as constraints, we explore simple photoionization models for the absorber for a wide range of densities and ionization parameters in an effort to reproduce the strengths of the UV absorption lines. We find that densities of at least 1x10^{11} cm^{-3} are needed. However, a single ionization parameter cannot explain all of the observed lines. An ionization parameter between 10^{-2.5} and 10^{-3.5} is needed for the Mg and Fe lines and the soft X-ray absorption, but lines from Si, C, Al, and H require different density-ionization parameter combinations. According to the models, such an absorbing medium must be located very close to the source of ionizing radiation (within 5,000 gravitational radii) and must be very compact. As such, the properties of this absorbing medium differ from those of more luminous quasars, but are reminiscent of the absorber in the Seyfert galaxy NGC 4151. We suggest that the absorber is in the form of thin sheets or filaments embedded in a wind wind that overlays the accretion disk of Arp 102B. This picture is consistent with all of the available constraints on the central engine of this object.

The model can be considered either as the theory of superconductivity or as the axial sector of QCD depending on the interpretation of the charge. We also provided a few models with linear confinement.

Characterisation techniques

description: While bulk materials have constant physical properties independent of their size, the physical and chemical properties of a nanoparticle are dictated by its size. Accurate characterisation of mean size, size distribution and shape is key to the efficient manufacturing of high-quality nanomaterials. The EU-funded NanoPAT project plans to use three new real-time analytical tools that overcome problems and limitations of conventional characterisation technologies. The new process analytical technologies (PAT) will be photon density wave spectroscopy, optofluidic force induction and turbidity spectrometry. The innovative technologies will be combined with new data analysis methods to provide, for the first time, real-time analysis of particles on the nanometre scale with sub-minute temporal resolution. The present document shows a summary of the most relevant characterization techniques used to measure particle sizes and size distribution. These techniques are classified in three main approaches depending on the particle size distribution (PSD) analysis, which are ensemble, separation and counting methods. Each of the methods explained in the present document are based on different physical principles and present their own advantages and limitations. Only few of the techniques reviewed are valid for online/inline analysis.

description: In recent years systematic experimental studies of the temperature dependence of the resistivity in a variety of dilute, ultra clean two dimensional electron/hole systems have revived the fundamental question of localization or, alternatively, the existence of a metal-insulator transition in the presence of strong electron-electron interactions in two dimensions. We argue that under the extreme conditions of ultra clean systems not only is the electron-electron interaction very strong but the role of other system specific properties are also enhanced. In particular, we emphasize the role of valleys in determining the transport properties of the dilute electron gas in silicon inversion layers (Si-MOSFETs). It is shown that for a high quality sample the temperature behavior of the resistivity in the region close to the critical region of the metal-insulator transition is well described by a renormalization group analysis of the interplay of interaction and disorder if the electron band is assumed to have two distinct valleys. The decrease in the resistivity up to five times has been captured in the correct temperature interval by this analysis, without involving any adjustable parameters. The considerable variance in the data obtained from different Si-MOSFET samples is attributed to the sample dependent scattering rate across the two valleys, presenting thereby with a possible explanation for the absence of universal behavior in Si-MOSFET samples of different quality.

description: The population dynamics of a trapped Bose-Einstein condensate, subject to the action of an external field, is studied. This field produces a spatio-temporal modulation of the trapping potential with the frequency close to the transition frequency between the ground state and a higher energy level. For the evolution equations of fractional populations, a critical line is found. It is demonstrated that there exists a direct analogy between dynamical instability at this line and critical phenomena at a critical line of an averaged system. The related critical indices are calculated. The spatio-temporal evolution of atomic density is analyzed.

description: While bulk materials have constant physical properties independent of their size, the physical and chemical properties of a nanoparticle are dictated by its size. Accurate characterisation of mean size, size distribution and shape is key to the efficient manufacturing of high-quality nanomaterials. The EU-funded NanoPAT project plans to use three new real-time analytical tools that overcome problems and limitations of conventional characterisation technologies. The new process analytical technologies (PAT) will be photon density wave spectroscopy, optofluidic force induction and turbidity spectrometry. The innovative technologies will be combined with new data analysis methods to provide, for the first time, real-time analysis of particles on the nanometre scale with sub-minute temporal resolution. This deliverable discusses the state-of-the-art measurement techniques in the context of particle sizing and industrial application. Inline and offline techniques are shortly discussed, with a focus on the inline applicability of the considered techniques. In this discussion the terms inline, online and atline need to be discriminated. Inline monitoring will happen directly inside the process, at best faster than observable process changes. Online analysers are connected to the process (e.g. in a bypass) and ideally have a similar time resolution like inline analysers. Atline devices are separated but close to the process, while offline analysis happens spatially and timely separated.

A website with the domain www.nanopat.eu was created and published for the EU project NanoPAT, which is an European Union’s Horizon 2020 Research and Innovation Program, under the Grant Agreement number 862583. The purpose of this website is to communicate and disseminate project relevant information (main ideas and objectives, work plan, beneficiaries, progress of the tasks, internal / relevant external events, activities, news, project outputs, etc.) to the general public. This deliverable is part of the work package 7 (WP7) – Knowledge Transfer and Dissemination. The project partner BNN was responsible for developing the project website. This document presents the project website and the logo that have been developed. The project website will be one of the main channels for communication and dissemination of project objectives, activities and outcomes. Therefore, it will be regularly updated to provide continuous information about the project to both the Commission, scientific and industrial communities, and the general public.
Non-perturbative Gauge Groups and Local Mirror Symmetry

description: We analyze D-brane states and their central charges on the resolution of C^2/Z_n by using local mirror symmetry. There is a point in the moduli space where all n(n-1)/2 branches of the principal component of the discriminant locus coincide. We argue that this is the point where compactifications of Type IIA theory on a K3 manifold containing such a local geometry acquire a non-perturbative gauge symmetry of the type A_{n-1}. This analysis, which involves an explicit solution of the GKZ system of the local geometry, explains how the quantum geometry exhibits all positive roots of A_{n-1} and not just the simple roots that manifest themselves as the exceptional curves of the classical geometry. We also make some remarks related to McKay correspondence.

Inviscid coalescence of drops

description: We study the coalescence of two drops of an ideal fluid driven by surface tension. The velocity of approach is taken to be zero and the dynamical effect of the outer fluid (usually air) is neglected. Our approximation is expected to be valid on scales larger than $\ell_ν = ρν^2/σ$, which is $10 nm$ for water. Using a high-precision boundary integral method, we show that the walls of the thin retracting sheet of air between the drops reconnect in finite time to form a toroidal enclosure. After the initial reconnection, retraction starts again, leading to a rapid sequence of enclosures. Averaging over the discrete events, we find the minimum radius of the liquid bridge connecting the two drops to scale like $r_b \propto t^{1/2}$.
Coarse-grained loop algorithms for Monte Carlo simulation of quantum spin systems

description: Recently, Syljuasen and Sandvik proposed a new framework for constructing algorithms of quantum Monte Carlo simulation. While it includes new classes of powerful algorithms, it is not straightforward to find an efficient algorithm for a given model. Based on their framework, we propose an algorithm that is a natural extension of the conventional loop algorithm with the split-spin representation. A complete table of the vertex density and the worm-scattering probability is presented for the general XXZ model of an arbitrary S with a uniform magnetic field.

L-Platooning: A Protocol for Managing a Long Platoon with DSRC

Subjects: subject: Networking and Internet Architecture (cs.NI)

description: Vehicle platooning is an automated driving technology that enables a group of vehicles to travel very closely together as a single unit to improve fuel efficiency and driver safety and reduces CO2 emission. The significant benefits of platooning attracted huge interests from academia and industry, especially from logistics companies for utilizing platoons of "long-body" trailer trucks because of the huge cost savings. In this paper, we demonstrate that existing DSRC-based platooning solutions, however, fail to support formation of such "long" platoons consisting of typical trailer trucks because of the limited communication range of DSRC. To address this problem, we propose L-Platooning, the first platooning protocol that enables seamless, reliable, and rapid formation of a long platoon. We introduce a novel concept called Virtual Leader that refers to a vehicle that acts like a platoon leader to extend the coverage of the original platoon leader. A virtual leader election algorithm is developed to effectively designate a virtual leader based on the novel metric called the Virtual Leader Quality Index (VLQI) which quantifies the effectiveness of a vehicle serving as a platoon leader. We also develop mechanisms for L-Platooning to support the vehicle join and leave maneuvers specifically for a long platoon. Through extensive simulations using the combination of Veins (Plexe) and SUMO, we demonstrate that L-Platooning enables long-body trailer trucks to form a long platoon effectively and maintain the desired inter-vehicle distance precisely. We also show that L-Platooning handles seamlessly the vehicle join and leave maneuvers for a long platoon.

description: We present a molecular dynamics (MD) implementation of an extended statistical mechanical ensemble that includes ‘alchemical’ degrees of freedom describing particle attributes as thermodynamic variables. We demonstrate the use of this alchemical MD method in inverse design simulations of particles interacting via the Oscillating Pair Potential (OPP) and the Lennard–Jones–Gauss potential (LJG) – two general, previously studied models for which phase diagrams are known. We show that alchemical MD can quickly and efficiently optimise pair potentials for target structures within a specified design space in the low-temperature regime, where internal energy adequately represents the features of the alchemical free energy landscape. We show that alchemical MD can be also used to inversely design pair potentials to achieve target materials properties (here, bulk modulus) directly, without explicit knowledge of the structure–property relationship. Alchemical MD can easily be generalised and applied to any target materials properties or structures and used with any differentiable interaction potential.
