description: Observations by the Interface Region Imaging Spectrograph (IRIS) in the Mg II h & k spectral lines have provided a new diagnostic window towards the knowledge of the complex physical conditions in the solar chromosphere. Theoretical efforts focused on understanding the behavior of these lines have allowed us to obtain a better and more accurate vision of the chromosphere. These efforts include forward modeling, numerical simulations, and inversions. In this paper, we focus our attention on the uncertainties associated with the thermodynamic model atmosphere obtained after the inversion of the Mg II h & k lines. We have used ~ 50;000 synthetic representative profiles of the IRIS2 database to characterize the most important source of uncertainties in the inversion process, viz.: the inherent noise of the observations, the random initialization of process, and the selection criteria in a high-dimensional space. We have applied a Monte Carlo approach to this problem. Thus, for a given synthetic representative profile, we have created five randomized noise realizations (representative of the most popular exposure times in the IRIS observations), and inverted these profiles five times with different inversion initializations. The resulting 25 inverted profiles, fits to noisy data, and model atmospheres are then used to determine the uncertainty in the model atmosphere, based on the standard deviation and empirical selection criteria for the goodness of fit. With this approach, the new uncertainties of the models available in the IRIS2 database are more reliable at the optical depths where the Mg II h & k lines are sensitive to changes in the thermodynamics.

description: Topologically protected swirl of the magnetic texture known as the Skyrmion has become ubiqui- tous in both metallic and insulating chiral magnets. Meanwhile the existence of its three-dimensional analogue, known as the magnetic monopole, has been suggested by various indirect experimental sig- natures in MnGe compound. Theoretically, Ginzburg-Landau arguments in favor of the formation of a three-dimensional crystal of monopoles and anti-monopoles have been put forward, however no microscopic model Hamiltonian was shown to support such a phase. Here we present strong numerical evidence from Monte Carlo simulations for the formation of a rock-salt crystal structure of monopoles and anti-monopoles in short-period chiral magnets. Real-time simulation of the spin dynamics suggests there is only one collective mode in the monopole crystal state in the frequency range of several GHz for the material parameters of MnGe.

Single-photon Quantum Router by Two Distant Artificial Atoms

description: Nowadays, quantum router is playing a key role in quantum communication and quantum network- s. Here we propose a tunable single-photon routing scheme, based on quantum interference, which uses two distant artificial atoms coupling to two transmission lines. Depending on the distance between the two atoms, the collective effect will lead to destructive or constructive interference between the scattered photons. Under standing wave condition, single photon from the incident channel can be perfectly transmitted or redirected into another channel by asymmetric or symmet- ric reflected phase shift of atoms, respectively. Therefore, we show that our router can be controlled by adjusting the detuning of the atoms and interatomic distance, without any classical field.

description: The energy-efficient Adapteva Epiphany architecture exhibits massive many-core scalability in a physically compact 2D array of RISC cores with a fast network-on-chip (NoC). The architecture presents many features and constraints which contribute to software design challenges for the application developer. Addressing these challenges within the software stack that supports application development is critical to improving productivity and expanding the range of applications for the architecture. We report here on advances that have been made in the COPRTHR-2 software stack targeting the Epiphany architecture that address critical issues identified in previous work. Specifically, we describe improvements that bring greater control and precision to the design of compact compiled binary programs in the context of the limited per-core local memory of the architecture. We describe a new design for run-time support that has been implemented to dramatically improve the program load and execute performance and capabilities. Finally, we describe developments that advance host-coprocessor interoperability to expand the functionality available to the application developer.

description: Although red giants deplete lithium on their surfaces, some giants are Li-rich. Intermediate-mass asymptotic giant branch (AGB) stars can generate Li through the Cameron-Fowler conveyor, but the existence of Li-rich, low-mass red giant branch (RGB) stars is puzzling. Globular clusters are the best sites to examine this phenomenon because it is straightforward to determine membership in the cluster and to identify the evolutionary state of each star. In 72 hours of Keck/DEIMOS exposures in 25 clusters, we found four Li-rich RGB and two Li-rich AGB stars. There were 1696 RGB and 125 AGB stars with measurements or upper limits consistent with normal abundances of Li. Hence, the frequency of Li-richness in globular clusters is (0.2 +/- 0.1)% for the RGB, (1.6 +/- 1.1)% for the AGB, and (0.3 +/- 0.1)% for all giants. Because the Li-rich RGB stars are on the lower RGB, Li self-generation mechanisms proposed to occur at the luminosity function bump or He core flash cannot explain these four lower RGB stars. We propose the following origin for Li enrichment: (1) All luminous giants experience a brief phase of Li enrichment at the He core flash. (2) All post-RGB stars with binary companions on the lower RGB will engage in mass transfer. This scenario predicts that 0.1% of lower RGB stars will appear Li-rich due to mass transfer from a recently Li-enhanced companion. This frequency is at the lower end of our confidence interval.

description: Research on actinide materials, both basic and applied, has been greatly advanced by the general techniques available from high-intensity photon beams from x-ray synchrotron sources. The most important single reason is that such x-ray sources can work with minute (e.g., microgram) samples, and at this level, the radioactive hazards of actinides are much reduced. We start by discussing the form and encapsulation procedures used for different techniques, then discuss the basic theory for interpreting the results. By reviewing a selection of x-ray diffraction (XRD), resonant elastic x-ray scattering (REXS), x-ray magnetic circular dichroism (XMCD), resonant and non-resonant inelastic scattering (RIXS, NIXS), dispersive inelastic x-ray scattering (IXS), and conventional and resonant photoemission experiments, we demonstrate the potential of synchrotron radiation techniques in studying lattice and electronic structure, hybridization effects, multipolar order, and lattice dynamics in actinide materials.

description: The volunteer tourism sector has received extensive attention in recent years, yet those working in it remain understudied in the growing body of literature. This paper uses a multiphasic approach to explore Chinese advisors' roles in volunteer tourism sending organisations. Semi-structured interviews with advisors showed that they held various roles in different phases of volunteer tourism, and four overarching roles, namely, professional, supporter, influencer, and self-actualiser, were also changed in the process. Through a multiphasic analysis, this study will contribute to understanding advisor roles both in volunteer tourism and Chinese contexts. This study can also help advisors understand their roles and responsibilities to further develop their roles and formulate their career beliefs and paths.
On the collisional damping of plasma velocity space instabilities

Year: 2022
Subjects: subject: Plasma Physics (physics.plasm-ph)

description: For plasma velocity space instabilities driven by particle distributions significantly deviated from a Maxwellian, weak collisions can damp the instabilities by an amount that is significantly beyond the collisional rate itself. This is attributed to the dual role of collisions that tend to relax the plasma distribution toward a Maxwellian and to suppress the linearly perturbed distribution function. The former effect can dominate in cases where the unstable non-Maxwellian distribution is driven by collisionless transport on a time scale much shorter than that of collisions, and the growth rate of the ideal instability has a sensitive dependence on the distribution function. The whistler instability driven by electrostatically trapped electrons is used as an example to elucidate such a strong collisional damping effect of plasma velocity space instabilities, which is confirmed by first-principles kinetic simulations.

description: The aim of this work is to present a dedicated Solar Polygeneration System (PROTEAS System) for the simultaneous production of electricity, hot water and air-conditioning. The core of the PROTEAS System is the innovative setup of Total Internal Reflection Reflectors made of plastic (Primary Optical System), which concentrate the solar rays up to 5,000 suns, homogenized to 1,000 suns by specially designed Total Internal Reflection Homogenizers (Secondary Optical System). High-efficiency Photovoltaic Cells are used to generate electricity. Furthermore, water -used for cooling down the photovoltaic cells- is heated up to 85-90°C and with the use of an advanced Absorption NH3 Heat Pump, is turned to chilled water for air-conditioning (7-12°C) and subsequently to domestic warm water about 45-55°C. PROTEAS modules are suitably spaced on a low-profile metallic ring which tracks the sun. The engineering of the system has already been initiated and some of the subsystems have been successfully developed. PROTEAS will be installed and evaluated in a building under real operational conditions in order to demonstrate the feasibility of the investment in terms of energy savings and assess its potential as a new market solution, which can be both cost effective and environmentally friendly.

description: The scope of this investigation is to study the requirements for a CPV system, integrated in the built environment. The basic advantage of such a system is that a large fraction of the available solar energy can be converted to useful energy, Additional benefits are: good illumination and crop yield (in greenhouses) by using the remaining diffuse light and better indoor climate circumstances, by means of capture of the energy-rich direct radiation. This investigation focusses on optimization of solar tracking, which is needed for CPV systems. Our solution is using an algorithm which predicts the position of the sun with high accuracy, without using excessive computation time. It is an improvement of an existing algorithm which allows accurate tracking even when the sun is at low altitude. Validation with astronomical reference data shows an average zenith angle error of less than 0.004°. The improved algorithm was still sufficiently lightweight to be implemented on a PLC system. The PLC thus could track in autonomous mode, independent of sensor data, which are easily interrupted in the built environment. We have completed this solar tracking implementation by using a common GPS receiver for time and global position input, as well as a pyranometer for monitoring of weather conditions.

description: We propose novel buffer layers consisting of the layered defect zincblende -type (InxGa1-x)2Se3 compounds for the GaAs on Si(111) system and for epitaxial lift-off (ELO) technique. The layered structured materials are suitable for lattice mismatch and thermal expansion mismatch buffer layers. Furthermore, the III-V overlayer can be transferred onto a support substrate by spalling from Si substrate via van der Waals interface of (InxGa1-x)2Se3 layer. For use of the buffer layer, it is necessary to grow -type (InxGa1-x)2Se3 preferentially without growing other compositions and polytype structures. The purpose of this study is to grow -In2Se3 preferentially and to demonstrate the transfer of -type In2Se3 layer. We investigated In2Se3 growth on GaAs(111) just and vicinal substrates by MBE and characterized its crystal structure type and the lattice parameters by XRD and Raman spectroscopy. The inclusion of other InxSey can be avoided by use of the vicinal substrates. We successfully demonstrated the transfer of -type In2Se3 layer onto glass substrate by spalling from GaAs substrate via van der Waals interface. We propose this layer transfer technique is applicable to the fabrication of thin film flexible multi-junction solar cells.

description: Alzheimer’s disease is a neurodegenerative disorder characterized by the accumulation of β-amyloid (Aβ) plaques and hyperphosphorylated tau protein in the brain. These pathological changes can ultimately be the cause of neuronal degeneration, and neuron loss leading to memory problems, which are characteristic of the disease. This project explores the dynamics of both Aβ plaque deposition and tau hyperphospho- rylation, and their relationship with the excess of extracellular glutamate which can induce excitotoxicity. The purpose of this project is to describe how these factors impact the synaptic functioning leading to interference in signal transmission, reduced synaptic plasticity and neuron loss. Through a mathematical model based on differential equations, this paper describes how the formation of β-amyloid plaques can induce the excessive release of glutamate, which will then trigger multiple kinase signaling pathways re- sponsible for the hyperphosphorylation of tau. This results in the formation of intracellular tangles that block neuronal communication, and can lead to eventual neuronal death.

description: In recent years, both solar cell research and nanowire research have become popular topics in design and fabrication of semiconductor devices. The need for higher solar cell efficiencies at lower cost has been the main concern of scientists and engineers. Nanowire solar cell is one candidate for decreasing the cost of solar cell fabrication. The nanowire geometry has many advantages over planar bulk and thin-film solar cells in processes of photoconversion. They reduce the quantity and quality of material necessary to obtain the limits, which leads to lower cost. In addition, complex single-crystalline nanowires are able to be fabricated directly on low-cost substrates and electrodes. In this work, we simulate single vertical nanowire solar cell made from InP with radial junction, in order to examine the influence of the different parameters of the cell structure on efficiency and compare it with axial junction cells. Length and diameter of the cell, thicknesses of regions, dopant type and concentration are these parameters. The simulations enable one to find the optimized structure and predict the fabrication process.
Quantum phase transitions in the triangular coupled-top model

description: We study the coupled-top model with three large spins located on a triangle. Depending on the coupling strength, there exist three phases: disordered paramagnetic phase, ferromagnetic phase, and frustrated antiferromagnetic phase, which can be distinguished by the mean-field approach. The paramagnetic-ferromagnetic phase transition is accompanied by the breaking of the global $Z_2$ symmetry, whereas the paramagnetic-antiferromagnetic phase transition is accompanied by the breaking of both the global $Z_2$ symmetry and the translational symmetry. Exact analytical results of higher-order quantum effects beyond the mean-field contribution, such as the excitation energy, quantum fluctuation, and von Neumann entropy, can be achieved by the Holstein-Primakoff transformation and symplectic transformation in the thermodynamic limit. Near the quantum critical point, the energy gap closes, along with the divergence of the quantum fluctuation in certain quadrature and von Neumann entropy. Particular attention should be paid to the antiferromagnetic phase, where geometric frustration takes effect. The critical behaviors in the antiferromagnetic phase are quite different from those in the paramagnetic and ferromagnetic phases, which highlight the importance of geometric frustration. The triangular coupled-top model provides a simple and feasible platform to study the quantum phase transition and the novel critical behaviors induced by geometric frustration.

description: Stellar winds from active solar type stars can play a crucial role in removal of stellar angular momentum and erosion of planetary atmospheres. However, major wind properties except for mass loss rates cannot be directly derived from observations. We employed a three dimensional magnetohydrodynamic Alfven wave driven solar wind model, ALF3D, to reconstruct the solar wind parameters including the mass loss rate, terminal velocity and wind temperature at 0.7, 2 and 4.65 Gyr. Our model treats the wind thermal electrons, protons and pickup protons as separate fluids and incorporates turbulence transport, eddy viscosity, turbulent resistivity, and turbulent heating to properly describe proton and electron temperatures of the solar wind. To study the evolution of the solar wind, we specified three input model parameters, the plasma density, Alfven wave amplitude and the strength of the dipole magnetic field at the wind base for each of three solar wind evolution models that are consistent with observational constrains. Our model results show that the velocity of the paleo solar wind was twice as fast, about 50 times denser and 2 times hotter at 1 AU in the Suns early history at 0.7 Gyr. The theoretical calculations of mass loss rate appear to be in agreement with the empirically derived values for stars of various ages. These results can provide constraints for wind dynamic pressures on magnetospheres of (exo)planets around the young Sun and other active stars, which is crucial in realistic assessment of the Joule heating of their ionospheres and corresponding effects of atmospheric erosion.

description: Ultrathin GaN nanowires (NWs) are attractive to maximize surface effects and as building block in high-frequency transistors. Here, we introduce a facile route for the top-down fabrication of ordered arrays of GaN NWs with aspect ratios exceeding $10$ and diameters below $20\,$nm. Highly uniform thin GaN NWs are first obtained by using electron beam lithography to pattern a Ni/SiN$_x$ hard mask, followed by dry etching and wet etching in hot KOH. The SiN$_x$ is found to work as an etch stop during wet etching in hot KOH. Arrays with NW diameters down to $(33 \pm5)\,$nm can be achieved with a yield exceeding $99.9\,\%$. Further reduction of the NW diameter down to $5\,$nm is obtained by applying digital etching which consists in plasma oxidation followed by wet etching in hot KOH. The NW radial etching depth is tuned by varying the RF power during plasma oxidation. NW breaking or bundling is observed for diameters below $\approx 20\,$nm, an effect that is associated to capillary forces acting on the NWs during sample drying in air. This effect can be principally mitigated using critical point dryers. Interestingly, this mechanical instability of the NWs is found to occur at much smaller aspect ratios than what is predicted for models dealing with macroscopic elastic rods. Explicit calculations of buckling states show an improved agreement when considering an inclined water surface, as can be expected if water assembles into droplets. The proposed fabrication route can be principally applied to any GaN/SiN$_{x}$ nanostructures and allows regrowth after removal of the SiN$_{x}$ mask.

description: We show that two particles interacting via spin exchange exhibit topological features found in one-dimensional single particle lattice models. This is accomplished by absorbing all of the spatial degrees of freedom of the lattices into the spin degrees of freedom of the two particles. Comparing the spin system with the Su-Schrieffer-Heeger model, we show the existence of topologically protected edge spin states and establish the bulk-edge correspondence. Modifying the spin system with a chiral symmetry breaking term results in it resembling the Rice-Mele model and can therefore act as a Thouless spin pump of one of the particles when periodically and adiabatically driven. By using the spin states as a synthetic spatial dimension, we show two particles are enough to simulate well known topological properties in condensed matter physics.

III-V-based Multi-junction Solar Cells, Concentrator Solar Cells and Space Solar Cells

description: 29th European Photovoltaic Solar Energy Conference and Exhibition; 2050-2053
description: Concentrator 4-junction or 5-junction solar cells have great potential for realizing super high-efficiency of over 50%. In order to realize super high-efficiency of more than 50%, it is substantially important to understand and reduce several losses of solar cells. This paper reviews loss mechanism for III-V compound solar cells and materials, especially surface recombination loss. Regarding the differences of surface recombination velocities in semiconductor materials, differences of point defect behavior are thought to be one of the mechanisms.

description: Deep learning semantic segmentation algorithms have provided improved frameworks for the automated production of Land-Use and Land-Cover (LULC) maps, which significantly increases the frequency of map generation as well as consistency of production quality. In this research, a total of 28 different model variations were examined to improve the accuracy of LULC maps. The experiments were carried out using Landsat 5/7 or Landsat 8 satellite images with the North American Land Change Monitoring System labels. The performance of various CNNs and extension combinations were assessed, where VGGNet with an output stride of 4, and modified U-Net architecture provided the best results. Additional expanded analysis of the generated LULC maps was also provided. Using a deep neural network, this work achieved 92.4% accuracy for 13 LULC classes within southern Manitoba representing a 15.8% improvement over published results for the NALCMS. Based on the large regions of interest, higher radiometric resolution of Landsat 8 data resulted in better overall accuracies (88.04%) compare to Landsat 5/7 (80.66%) for 16 LULC classes. This represents an 11.44% and 4.06% increase in overall accuracy compared to previously published NALCMS results, including larger land area and higher number of LULC classes incorporated into the models compared to other published LULC map automation methods.

description: Within the European funded project SOPHIA, a Round Robin measurement on CPV modules has been initiated. Seven different test laboratories located in Europe between 48 °N and 37 °N are participating in performing measurements of four SOITEC CPV modules. The modules are electrically characterized with different measurement equipment under various climatic conditions. A pyrheliometer and a spectral sensor, based on component cells, are being shipped together with the modules. This ensures that the irradiance and spectrum, two factors with high impact on CPV module performance, are measured with the identical equipment at each site. The round robin activity is being performed in close co-operation with the IEC TC82 WG7 power rating team in order to support the work on the CPV module power rating draft standard 62670-3. The resulting rated module power outputs at CSOC (Concentrator Standard Operating Conditions) are being compared amongst the power rating methods and amongst the test labs. In this manner, a deviation in rated power output between different test labs and power rating methods are being determined.

description: We study the maximum norm behavior of $L^2$-normalized random Fourier cosine series with a prescribed large wave number. Precise bounds of this type are an important technical tool in estimates for spinodal decomposition, the celebrated phase separation phenomenon in metal alloys. We derive rigorous asymptotic results as the wave number converges to infinity, and shed light on the behavior of the maximum norm for medium range wave numbers through numerical simulations. Finally, we develop a simplified model for describing the magnitude of extremal values of random Neumann Fourier series. The model describes key features of the development of maxima and can be used to predict them. This is achieved by decoupling magnitude and sign distribution, where the latter plays an important role for the study of the size of the maximum norm. Since we are considering series with Neumann boundary conditions, particular care has to be placed on understanding the behavior of the random sums at the boundary.

description: Although weak lensing (WL) is a powerful method to estimate a galaxy cluster mass without any dynamical assumptions, a model bias can arise when the cluster density profile departs from the assumed model profile. In a merging system, the bias is expected to become most severe because the constituent halos undergo significant structural changes. In this study, we investigate WL mass bias in binary cluster mergers using a suite of idealized hydrodynamical simulations. Realistic WL shear catalogs are generated by matching the source galaxy properties, such as intrinsic shape dispersion, measurement noise, source densities, etc., to those from Subaru and {\it Hubble Space Telescope} observations. We find that, with the typical mass-concentration ($M$-$c$) relation and the Navarro-Frenk-White (NFW) profile, the halo mass bias depends on the time since the first pericenter passage and increases with the mass of the companion cluster. The time evolution of the mass bias is similar to that of the concentration, indicating that, to first order, the mass bias is modulated by the concentration change. For a collision between two $\sim10^{15}~M_{\odot}$ clusters, the maximum bias amounts to $\sim60\%$. This suggests that previous WL studies may have significantly overestimated the mass of the clusters in some of the most massive mergers. Finally, we apply our results to three merger cases: Abell 2034, MACS J1752.0+4440, and ZwCl 1856.8+6616, and report their mass biases at the observed epoch, as well as their pre-merger masses, utilizing their merger shock locations as tracers of the merger phases.

description: The atomic mass difference of 163Ho and 163Dy has been directly measured with the Penning trap mass spectrometer SHIPTRAP applying the novel phase imaging ion cyclotron resonance technique. Our measurement has solved the long standing problem of large discrepancies in the Q value of the electron capture in 163Ho determined by different techniques. Our measured mass difference shifts the current Q value of 2555(16) eV evaluated in the Atomic Mass Evaluation 2012 [G. Audi et al., Chin. Phys. C 36, 1157 (2012)] by more than 7 sigma to 2833(30stat)(15sys) eV/c2. With the new mass difference it will be possible, e.g., to reach in the first phase of the ECHo experiment a statistical sensitivity to the neutrino mass below 10 eV, which will reduce its present upper limit by more than an order of magnitude.

description: A pulsed solar simulator for CPV modules, consisting of a Xenon flash lamps system and a parabolic mirror was developed. I-V characteristics can be measured in a single flash with high reproducibility. Different commercial CPV modules were characterized indoor and outdoor at different sites (Cologne and Arizona). The acceptance angle of six commercial CPV module types was determined by tilting of the modules and by the Luminescence Inverse Method.
