description: Ring, or cyclic, polymers have unique properties compared to linear polymers, due to their topologically closed structure that has no beginning or end. Experimental measurements on molecular ring polymers are challenging due to their polydispersity in molecular weight and the presence of undesired side products such as chains. Here, we study an experimental model system for cyclic polymers, that consists of rings of flexibly-linked micron-sized colloids with $n$=4..8 segments. We characterize the conformations of these flexible colloidal rings and find that they are freely-jointed up to steric restrictions. We measure their diffusive behavior and compare it to hydrodynamic simulations. Interestingly, flexible colloidal rings have a larger translational and rotational diffusion coefficient compared to colloidal chains. In contrast to chains, their internal deformation mode shows slower fluctuations for $n\lesssim 8$ and saturates for higher values of $n$. We show that constraints stemming from the ring structure cause this decrease in flexibility for small $n$ and infer the expected scaling of the flexibility as function of ring size. Our findings could have implications for the behavior of both synthetic and biological ring polymers, as well as for the dynamic modes of floppy colloidal materials.

description: Single-emitter microscopy has emerged as a promising method of imaging nanostructures with nanoscale resolution. This technique uses the centroid position of an emitters far-field radiation pattern to infer its position to a precision that is far below the diffraction limit. However, nanostructures composed of high-dielectric materials such as noble metals can distort the far-field radiation pattern. Nanoparticles also exhibit a more complex range of distortions, because in addition to introducing a high dielectric surface, they also act as efficient scatterers. Thus, the distortion effects of nanoparticles in single-emitter microscopy remains poorly understood. Here we demonstrate that metallic nanoparticles can significantly distort the accuracy of single-emitter imaging at distances exceeding 300 nm. We use a single quantum dot to probe both the magnitude and the direction of the metallic nanoparticle-induced imaging distortion and show that the diffraction spot of the quantum dot can shift by more than 35 nm. The centroid position of the emitter generally shifts away from the nanoparticle position, in contradiction to the conventional wisdom that the nanoparticle is a scattering object that will pull in the diffraction spot of the emitter towards its center. These results suggest that dielectric distortion of the emission pattern dominates over scattering. We also show that by monitoring the distortion of the quantum dot diffraction spot we can obtain high-resolution spatial images of the nanoparticle, providing a new method for performing highly precise, sub-diffraction spatial imaging. These results provide a better understanding of the complex near-field coupling between emitters and nanostructures, and open up new opportunities to perform super-resolution microscopy with higher accuracy.

The model consists of a reaction-diffusion-taxis equation for the density of tumor cells coupled with an ODE for the density of tissue fibers and allows for strong degeneracy both in the diffusion and the haptotaxis terms. In this setting we prove the global existence of weak solutions to an associated no-flux initial-boundary value problem.

description: Comprehensive knowledge about the influence of the additive composition on the degradation behavior of the most
important photovoltaic (PV) module encapsulant, ethylene vinyl actetate (EVA), is crucial for enhancing its durability. To analyze
this influence, EVA foils with different additive compositions were exposed to UV irradiation (135 W/m2) at 60 °C with a UV-A
lamp, and characterized by spectroscopic methods (UV-vis, Raman spectroscopy) and DSC measurements. The reference foil with
minimal additives showed significant changes in consistency during UV exposure. Those changes were explained by chain
scissions, changes in conformation and crystallinity. In particular, degradation induced changes in the intensity of the symmetric
compared to the asymmetric CH2 stretching vibrations, detected by Raman spectroscopy, indicate modifications in the
conformational and crystalline setup. Therefore, their intensity ratio offers a nondestructive method to follow EVA degradation in
PV modules. A major influence of additives on the development of fluorescent and chromophoric species was found. A quenching
effect of oxygen on the development of fluorescent species was observed.

Photonic band gap opening physics under inversion symmetry breaking is revisited by the viewpoint of nonzero valley Chern number. Bulk valley modes with opposite orbital angular momentum are unveiled by inspecting time-varying electric fields. Topological transition is well illustrated through photonic Dirac Hamiltonian. Valley dependent edge states and the associated valley-protected backscattering suppression around Z-shape bend waveguide have been demonstrated.

description: In this paper we demonstrate the only available scalable information bounds for quantities of interest of high dimensional probabilistic models. Scalability of inequalities allows us to (a) obtain uncertainty quantification bounds for quantities of interest in the large degree of freedom limit and/or at long time regimes; (b) assess the impact of large model perturbations as in nonlinear response regimes in statistical mechanics; (c) address model-form uncertainty, i.e. compare different extended models and corresponding quantities of interest. We demonstrate some of these properties by deriving robust uncertainty quantification bounds for phase diagrams in statistical mechanics models.

description: A specific diagnosis and Test-To-Failure protocol has been defined and applied to different PV modules that developed an early yellowing after being installed in the field during less than 2 years. The study has been done by using comparison with modules of the same manufacturer that were installed in same circumstances and did not show the yellowing defect. After an initial characterization of a high number of yellowed and notyellowed modules, the analysis of the evolution, mostly with added doses of damp heat, has allowed identifying the potential risk of failure in the field associated to the yellowing effect of those modules. The main diagnosis tests of the IEC61215 Standard have been applied for intermediate characterization of the modules, as well as the electroluminescence technique. Finally, a layer by layer analysis has been performed to some modules to confirm the
results obtained.

description: Hot spots of crystalline silicon solar cells are a major failure mode for solar modules. In this work we
try to answer the question how hot spot cells behave first in bare state and second after lamination. For this study bare
cells are initially characterized and sorted by hot spot risk. An infrared camera is used to document temperature and
size of the hot spot when applying a reverse voltage of -12 V. Prone cells are then built into modules and a special hot
spot endurance test of the Photovoltaic Institute Berlin is performed where each cells gets shaded for 15 seconds. The
comparison of both test methods show a low correlation between the hot spot behavior of bare cells and laminated
cells. An extension of the shading time to up to 10 minutes proves that 15 seconds are sufficient to identify most of
the severe hot spots. Finally possible sorting criterions for cell or module manufacturer are discussed.

Moreover, we also prove that $f$ has topological entropy approximated by the topological entropy of $f$ restrict to basic hyperbolic sets. In particular, the topological entropy map is lower semicontinuous in a $C^1-$generic set of symplectic diffeomorphisms far from partial hyperbolicity.

description: Some small business (SB) are exiting their markets because their managers used ineffective strategies to improve business performance. Providing SB managers with an integrative view to identify effective strategies could enhance overall business performance (OBP), minimizing the risk of closing permanently. Grounded in the general system theory, the purpose of this qualitative multiple case study was to explore strategies that SB managers who received the Malcolm Baldrige National Quality Award between 2007 and 2018 in the United States used to achieve outstanding OBP. The participants were 6 high-level managers who participated in setting the strategies to improve OBP. Data were collected using semistructured interviews, the company’s 5-year performance analysis report, and member checking. Initial data were categorized in codes, and themes were identified, refined, and evaluated. Three major strategies SBs should use to secure outstanding OBP are: identify the reasons for a business to exist, identify the internal and external elements impacting the business performance, and understand the dynamic interaction among those elements for improvement. A recommendation for SB managers is to apply a systems approach, set plans, and identify effective strategies by considering the most impactful elements and their interaction for continuous improvement in line with the business mission realization Abstract

description: A set of identical, mobile agents is deployed in a weighted network. Each agent has a battery -- a power source allowing it to move along network edges. An agent uses its battery proportionally to the distance traveled. We consider two tasks : convergecast, in which at the beginning, each agent has some initial piece of information, and information of all agents has to be collected by some agent; and broadcast in which information of one specified agent has to be made available to all other agents. In both tasks, the agents exchange the currently possessed information when they meet. The objective of this paper is to investigate what is the minimal value of power, initially available to all agents, so that convergecast or broadcast can be achieved. We study this question in the centralized and the distributed settings. In the centralized setting, there is a central monitor that schedules the moves of all agents. In the distributed setting every agent has to perform an algorithm being unaware of the network. In the centralized setting, we give a linear-time algorithm to compute the optimal battery power and the strategy using it, both for convergecast and for broadcast, when agents are on the line. We also show that finding the optimal battery power for convergecast or for broadcast is NP-hard for the class of trees. On the other hand, we give a polynomial algorithm that finds a 2-approximation for convergecast and a 4-approximation for broadcast, for arbitrary graphs. In the distributed setting, we give a 2-competitive algorithm for convergecast in trees and a 4-competitive algorithm for broadcast in trees. The competitive ratio of 2 is proved to be the best for the problem of convergecast, even if we only consider line networks. Indeed, we show that there is no (2 -- $ε$)-competitive algorithm for convergecast or for broadcast in the class of lines, for any $ε$ \textgreater{} 0.

In this work, we take into account the de Sitter spacetime geometry, introduce our relativistic model by a technique based on the vanishing pressure Euler equations of relativistic compressible fluids on a (1+1)-dimensional background and construct a second order Godunov type finite volume scheme to examine numerical experiments within an analysis of the cosmological constant. Numerical results demonstrate the efficiency of the method for solutions containing shock and rarefaction waves.

description: The storage of energy in batteries is a cause of the failure and loss of reliability in PV systems.
Of the many types of batteries available, we will concentrate on lead-acid batteries, because these are the most frequently
used in photovoltaic application due to its relatively low cost and wide availability.
Batteries remain a complicated element, since they are the only dynamic element in a PV system. In fact, many
phenomenons can occur such as charge and discharge. Many parameters vary during these processes: voltage, current,
density, temperature, resistivity…etc. This leads to a complicated behavior of this element and thus makes predictions of
the state of charge much more complicated. Battery state of charge evolution usually consists of measuring manually the
electrolyte density; this method can only be employed by people in charge of the maintenance of an installation and is not
feasible for a private individual wishing to have at least daily information.
The selected model is that elaborated by Copetti. This model is general and normalized with battery capacity, it
necessitate few input parameters, it takes into account the discharge, the charge and the overcharge processes, and can be
applied for wide range of lead acid batteries used in PV systems.
The Copetti model presents a good performance to represent dynamic and complex battery operation.
This paper reviews this general lead acid batteries model and it agreement with experimental data obtained from tests
with in photovoltaic systems.
For checking the validity of the mathematical model, results of numerical simulation are compared with experimental
data of Varta Solar 100 Ah battery and Bergan Energy 100 Ah battery. We note easily that the correlation between
measured data and those calculated by the Copetti model for ambient temperature of 25 °C is good.

description: Most models that try to explain economic growth indicate exponential growth paths. In recent years, however, a lively discussion has emerged considering the validity of this notion. In the empirical literature dealing with drivers of economic growth, the majority of articles is based upon an implicit assumption of exponential growth. Few scholarly articles have addressed this issue so far. In order to shed light on this issue, we estimate autoregressive integrated moving average time series models based on Gross Domestic Product Per Capita data for 18 mature economies from 1960 to 2013. We compare the adequacy of linear and exponential growth models and conduct several robustness checks. Our fndings cast doubts on the widespread belief of exponential growth and suggest a deeper discussion on alternative economic grow theories.

description: We present far-infrared (FIR) $70-500\,μ$m imaging observations obtained with Herschel/PACS and SPIRE of 33 nearby (median distance of 30 Mpc) Seyfert galaxies from the Revised Shapley-Ames (RSA) catalogue. We obtain the FIR nuclear ($r=1\,$kpc and $r=2\,$kpc) and integrated spectral energy distributions (SEDs). We estimate the unresolved nuclear emission at 70 $μ$m and we fit the nuclear and integrated FIR SEDs with a grey body model. We find that the integrated FIR emission of the RSA Seyferts in our sample is dominated by emission from the host galaxy, with dust properties similar to those of normal galaxies (non AGN). We use four criteria to select galaxies whose nuclear $70\,μ$m emission has a significant AGN contribution: (1) elevated 70/160 $μ$m flux ratios, (2)spatially resolved, high dust temperature gradient, (3) $70\,μ$m excess emission with respect to the fit of the FIR SEDs with a grey body, and (4) excess of nuclear SFR obtained from $70\,μ$m over SFR from mid-infrared indicators. 16 galaxies (48 per cent of the initial sample) satisfy at least one of these conditions, whereas 10 satisfy half or more. After careful examination of these, we select six bona fide candidates (18 per cent of the initial sample) and estimate that $\sim 40-70$ per cent of their nuclear ($r=1-2\,$kpc) $70\,μ$m emission is contributed by dust heated by the AGN.

description: Abstract: Purpose - The present paper attempts to present the research that has been made on prediction models using deep learning methods with data retrieved from mimic III database and to identify challenges and possible areas for future research. Methodology - A literature research was conducted for articles related to MIMIC III and prediction models related to the database published from 2016 to 2021. Also, reviews and papers related to neural networks, machine learning, data mining and implementation and usage of electronic health records (EHR) in ICU were investigated to support findings from mimic III papers. Findings - Prediction algorithms can be very useful in ICU units. Although some algorithms, such as InSight are specialized in specific diseases, others such as XGBOOST and recurrent neural networks can be used in a broader area, presenting quite accurate results. Originality - Usually, reviews categorize research on MIMIC database per disease or per the desired outcome, such as the prediction of length of stay and the final outcome. The current study categorizes the research based on the tools, prediction models, and algorithms used. This way, it is possible to understand better how each method performs to various conditions and desired outcomes.

description: We analyze high-resolution UV spectra of a small sample of Herbig Ae/Be stars (HAEBES) in order to explore the origin of the $T\sim10^5$ K gas in these stars. The C IV 1548,1550 Å line luminosities are compared to non--simultaneous accretion rate estimates for the objects showing C IV emission. We show that the correlation between $L_{CIV}$ and $\dot{M}$ previously established for classical T Tauri stars (CTTSs) seems to extend into the HAEBE mass regime, although the large spread in literature $\dot{M}$ and $A_V$ values makes the actual relationship highly uncertain. With the exception of DX Cha, we find no evidence for hot, optically thick winds in our HAEBE sample. All other objects showing clear doublet emission in C IV can be well described by a two component (i.e., a single component for each doublet member) or four component (i.e., two components for each doublet member) Gaussian emission line fit. The morphologies and peak-flux velocities of these lines suggest they are formed in weak, optically thin stellar winds and not in an accretion flow, as is the case for the hot lines observed in CTTSs. The lack of strong outflow signatures and lack of evidence for line formation in accretion flows is consistent with the conclusion presented in our recent optical and He I 10830 Å studies that the immediate circumstellar environments of HAEBES, in general, are not scaled-up analogs of the immediate environments around CTTSs. The conclusions presented here for hot gas lines around HAEBES should be verified with a larger sample of objects.

description: One of the most fundamental properties of isotropic negative-index metamaterials, namely opposite directionality of the Poynting vector and the wavevector, enable many novel linear and nonlinear regimes of light-matter interactions. Here, we predict distinct characteristics of azimuthal modulation instability of optical vortices with different topological charges in negative-index metamaterials with Kerr-type and saturable nonlinearity. We derive an analytical expression for the spatial modulation-instability gain for the Kerr-nonlinearity case and show that a specific condition relating the diffraction and the nonlinear lengths must be fulfilled for the azimuthal modulation instability to occur. Finally, we investigate the rotation of the necklace beams due to the transfer of orbital angular momentum of the generating vortex on the movement of solitary necklace beams. We show that the direction of rotation is opposite in positive- and negative-index materials.

description: We consider the following class of equations with exponential nonlinearities on a compact surface $M$: $$ - Δu = ρ_1 \left( \frac{h_1 \,e^{u}}{\int_M h_1 \,e^{u} } - \frac{1}{|M|} \right) - ρ_2 \left( \frac{h_2 \,e^{-u}}{\int_M h_2 \,e^{-u} } - \frac{1}{|M|} \right), $$ which is associated to the mean field equation of the equilibrium turbulence with arbitrarily signed vortices. Here $h_1, h_2$ are smooth positive functions and $ρ_1, ρ_2$ are two positive parameters. We start by proving a concentration phenomena for the above equation, which leads to a-priori bound for the solutions of this problem provided $ρ_i\notin 8π\mathbb{N}, \, i=1,2$. Then we study the blow up behavior when $ρ_1$ crosses $8π$ and $ρ_2 \notin 8π\mathbb{N}$. By performing a suitable decomposition of the above equation and using the shadow system that was introduced for the $SU(3)$ Toda system, we can compute the Leray-Schauder topological degree for $ρ_1 \in (0,8π) \cup (8π,16π)$ and $ρ_2 \notin 8π\mathbb{N}$. As a byproduct our argument, we give new existence results when the underlying manifold is a sphere and a new proof for some known existence result.

description: In a state-of-the-art photovoltaic module the solar cell area accounts for about 85 to 90% of the total
module area. The rest of the module area is dominated by the back-sheet. Light impinging onto the back-sheets is
mostly reflected and a part of the reflected light is re-directed onto the solar cells. This photon recycling effect is well
known, but the efficiency of this process is not well understood until now. In this paper we present the results of a
study on the photon-recycling efficiency of different ISOVOLTAIC back-sheets and investigate the reasons for their
varying optical performances. A series of mono-cell-modules with different back-sheets was manufactured and
carefully investigated under Standard Test Conditions and by applying the Laser Beam Induced Current method. In
addition, the scattering properties of the back-sheets were measured which are the basis for the modelling of the
photon recycling efficiency. The experimental as well as the modelling results show good agreement. In particular it
is shown the photon recycling efficiency within a module significantly depends on the type of back-sheet used. The
average photon recycling efficiency of a typical module boarder region is found to range from about 19 to 23%,
depending on the type of back-sheet used.

description: The ionization of atoms with sequences of attosecond pulses gives rise to excited ionic states that are entangled with the emitted photoelectron. Still, the ionic ensemble preserves some coherence that can be controlled through the laser parameters. In helium, control of the $2s/2p$ He$^+$ coherence is mediated by the autoionizing states below the $N=2$ threshold [Phys. Rev. Res. {\bf 3}, 023233 (2021)]. In the present work we study the role of the resonances both below and above the $N=3$ threshold on the coherence of the $N=3$ He$^+$ ion, in the attosecond pump-probe ionization of the helium atom, which we simulate using the newstock \emph{ab initio} code. Due to the fine-structure splitting of the N=3 He$^+$ level, the ionic dipole beats on a picosecond timescale. We show how, from the dipole beating, it is possible to reconstruct the polarization of the ion at its inception.

description: As the main critical parts in a photovoltaic (PV) module are polymeric materials, the aging behavior of
backsheets is crucial for the whole photovoltaic module. In many standard backsheets polyethylene terephthalate (PET) is
used as core layer. This is the reason for the high influence of the aging behavior of PET on the whole backsheet and
therefore also on the whole PV module. Currently the standard test method for lifetime evaluation of backsheets of PV
modules is a damp heat (DH) test at 85°C and 85% relative humidity (RH) for up to 2000 hours (h). The test duration of
2000 h equals approximately 3 months, which is a long time for material development. Further acceleration can be
achieved by an increase of temperature, humidity and pressure – a so called pressure cooker test. To analyse differences
in thermal and mechanical properties the aging behaviour was investigated by differential scanning calorimetry (DSC)
and tensile tests. Thermal and mechanical properties showed a good correlation between pressure cooker at 120°C and
damp heat test, with the constraint of presumable differences in the failure mechanism.

Balance of System Components

description: 29th European Photovoltaic Solar Energy Conference and Exhibition; 3050-3053
description: In recent years, low-price competitions all over the world have made the PV industry suffer from severe losses, though total installed capacity of the PV systems has increased rapidly. As revealed in the literature, the AC module inverter or micro-inverter has become one of the trends for the future PV system development. Nevertheless, for single-stage AC module inverters[1]-[3], there often exists a large amount of power fluctuation with twice the grid frequency at the output side, causing high ripple components to appear at the PV module output [4]-[7]. The average generated power from the PV module is consequently decreased. In this paper, to implement and improve the power decoupling function [8]-[10], the proposed micro-inverter utilizes an auxiliary circuit to balance the instantaneous input DC and output AC power. The duty cycle of the main switch is determined by the input MPPT current command. Also, Resulting from the leakage energy being recycled, the voltage spike on the main switch can be clamped. The proposed micro-inverter is operated in discontinuous conduction mode (DCM) to ensure the operation function properly. In addition, the current falling rate of the secondary-side diodes is controlled by the magnetizing inductance of the transformer, which alleviates the reverse-recovery problem of the secondary-side diodes. The efficiency of the proposed micro-inverter can be increased accordingly.

description: Wetting behaviour of surfaces is believed to be affected by van der Waals (vdW) forces, however, there is no clear demonstration of this. With the isolation of two-dimensional vdW layered materials it is possible to test this hypothesis. In this paper, we report the wetting behaviour of vdW heterostructures which include, chemical vapor deposition (CVD) grown graphene, molybdenum disulfide (MoS2) and tungsten disulfide (WS2) on few layers of hexagon boron nitride (h-BN) and SiO2/Si. Our study clearly shows that while this class of two-dimensional materials are not wetting transparent, there seems to be a significant amount of influence on their wetting properties by the underlying substrate due to dominant vdW forces. Contact angle measurements indicate that graphene and graphene-like layered transitional metal dichalcogenides invariably have intrinsically dispersive surfaces with a dominating London-vdW force-mediated wettability. Electric field controlled wetting studies of MoS2/WS2/SiO2/Si heterostructures were performed and no notable changes to the water contact angle was seen with applied voltage although two orders of magnitude change in resistance was observed. We postulate that the highly dispersive nature of these surfaces arising from the predominant London-vdW forces could be the reason for such observation.

description: PV-powered lighting systems, light-to-light systems (L2L), offer outdoor lighting where it is elsewhere cumbersome to enable lighting. Application of these systems at high latitudes, where the difference in day length between summer and winter is large and the solar energy is low requires smart dimming functions for reliable lighting. In this work we have built a laboratory to characterize these systems up to 200 Wp from “nose to tail” in great details to support improvement of the systems and to make accurate field performance predictions.

description: We've performed precise measurements of electron scattering on molecular hydrogen and deuterium by using the "Troitsk nu-mass" setup. Electrons were generated by the electron gun with an energy line width better than 0.3 eV. The electron energies were 14, 17, 18.7, 19 and 25 keV. The windowless gaseous tritium source (WGTS) was filled by hydrogen isotopes and served as a target. The total column density was adjusted to form a length of 0.35--0.7 of the electron mean free path. The integral spectrum of scattered electrons was measured by the electrostatic spectrometer with a magnetic adiabatic collimation and relative energy resolution 8.3 10^{-5}. As a result, the shapes of molecular excitation and ionization spectra were extracted for both isotopes. We did not find any difference between hydrogen and deuterium targets. The relative energy dependence was extracted too.

description: In this paper, an active power control strategy is presented in order for a PV plant to operate at a specified suboptimal output power setpoint and maintain power reserves, expressed as a fraction of the maximum available power. Given that the latter is not known a priori, a quadratic curve fitting algorithm is applied to recent past measurements in order to estimate the P-V curve and calculate the operating voltage to achieve the desired power reserve levels. The proposed method offers sufficient accuracy, increased robustness and computational efficiency, combined with excellent dynamic response at irradiance variations and reserve command changes. The effectiveness of the control strategy and the P-V curve estimation method is validated by simulations in MATLAB/Simulink.
