description: Predicting the fate of ecologies is a daunting, albeit extremely important, task. As part of this task one needs to develop an understanding of the organization, hierarchies, and correlations among the species forming the ecology. Focusing on complex food networks we present a theoretical method that allows to achieve this understanding. Starting from the adjacency matrix the method derives specific matrices that encode the various inter-species relationships. The full potential of the method is achieved in a spatial setting where one obtains detailed predictions for the emerging space-time patterns. For a variety of cases these theoretical predictions are verified through numerical simulations.

description: Excerpts from the report: The Berkshire Region is located entirely within Berkshire County, the western most county in Massachusetts. The county extends the entire north-south length of the state, from Vermont to Connecticut. On the west, the county is bounded by the New York-Massachusetts border and on the east by the Connecticut River Valley (Franklin, Hampshire and Hampden Counties). The Berkshire Region is a trough-like area lying between the Taconic Mountain Range on the west (New York border) and the Berkshire Hills on the east (the eastern most towns in the county, with the exception of Washington, are not within the region). The region is further divided into two study areas, the Hudson and the Housatonic. The predominant land use in the Berkshire Region is forestland which covers nearly 70 percent (301,505 acres) of the region. Agricultural land comprises nearly 14 percent (34,374 acres of cropland and 26,391 acres of pastureland) of the region. There are nearly 30,000 acres of urban (residential, commercial-industrial and institutional) land in the Berkshire Region. Slightly more than four percent of the region is composed of wetlands (11,569 acres) and water surfaces (7,523 acres). Objectives of this report are to identify problems, needs and alternative solutions in the following resource areas: land use, flooding, erosion and sediment, recreation, fish and wildlife, wetlands, water supply and water quality.

description: In this paper we have considered a simple lattice gas model of chemisorbed monolayer which allows for the harmonic fluctuations of the bond length between the adsorbate atom and the surface site. The model also involves a short-ranged attractive potential acting between the adsorbed atoms as well as the surface periodic corrugation potential. It has been assumed that the adsorbed atoms are bonded to the uppermost layer of the substrate atoms. In particular, using Monte Carlo simulation method we have focused on the orderings appearing in the dense monolayer formed on the (111) face of an fcc solid. Within the lattice gas limit, the chemisorbed layer forms a (1x1) structure. On the other hand, when the bonds are allowed to fluctuate, three other different ordered phases have been found to be stable in the ground state. One of them has been found to be stable at finite temperatures and to undergo a phase transition to the disordered state. The remaining two ordered states have been found to be stable in the ground state only. At finite temperatures, the ordering has been demonstrated to be destroyed due to large entropic effects.

description: In the last decade, perovskite solar cell (PSC) technology showed an efficiency improvement from 9.7% to 25.2% approaching the Si record of more than 26%. The low-cost perspective of PSCs is achievable only if scalable processes in manufacturing conditions such as pilot line or plant factory are designed and optimized for the full device stack. Here, we demonstrate a semi-automatic and scalable solvent quenching/doublestep method, based on the blade-coating technique, to deposit the triple cation perovskite in ambient air on module size. We assess the homogeneity of the perovskite layer and of the full stack by scanning electron microscopy images and profilometry measurements. Moreover, we compared the efficiency of modules fabricated by different deposition procedures: blade-coating in ambient air, spin-coating in nitrogen air and ambient air. In the first case the efficiency was about 16%, while the spin-coating technique exhibited efficiencies about 15% and 13% in nitrogen and ambient air, respectively.

description: We have used electroluminescence to evaluate short-term stabilization process of perovskite solar cells. The cells were kept in the dark between periodic characterization sessions. In a characterization session, a cell was forward biased with a quarter of short circuit current density, while voltage was continuously logged and electroluminescence (EL) images were acquired. When a constant current forward bias was applied, the voltage on all cells immediately jumped to a certain level and then it gradually stabilized to a voltage around 1 V over the course of one to several minutes. Similar stabilization was observed for intensity of EL images. Based on the observed behaviour we differentiated four different stabilization types: positive exponential decay, overshoot, exponential rise continued with linear rise, and deficit. During the first three, the temporal EL emission can be predicted from applied voltage using reciprocity relation. However, during the deficit stabilization, the EL intensity, calculated from applied voltage, initially misses the measured EL intensity forming a kind of EL deficit. The observed stabilization processes were both, positive and negative. Spatial information from EL images reveals that when there is no EL deficit, the images mostly just change in intensity, but when EL deficit is present, the (in)homogeneity of the images also changes.

description: We investigated the use of Hamamatsu fine-mesh photomultiplier tube assemblies H6152-70 and H6614-70 with regards to their gain and timing resolution in magnetic fields up to 1.9 T. Our results show that the H6614-70 assembly can operate reliably in magnetic fields exceeding 1.5 T, while preserving a reasonable timing resolution even with a gain reduction of a factor of approximately 100. The reduction of the relative gain of the H6152-70 is similar to the H6614-70's near 1.5 T, but its timing resolution worsens considerably at this high field.

description: Lead halide perovskites are a class of semiconductor materials which are employed as non-intentionally doped absorbers inserted between two selective carrier transport layers (SCTL), realizing a p-i-n or n-i-p heterojunction. In our study, we have developed and investigated a lateral device, based on methylammonium lead iodide (MAPbI3) in which the p-i-n heterojunction develops in the horizontal direction. Our research suggests that the effective doping level in the MAPbI3 film should be very low, below 1012 cm-3. Along the vertical direction, this doping level is not enough to screen the electric field of the buried heterojunction with the SCTL. The perovskite work function is therefore affected by the work function of the SCTL underneath. From drift-diffusion simulations we show that intrinsic perovskite-SCTL structures develop mV range surface photovoltages (SPVs) under continuous illumination. However, perovskite-SCTL structures can develop SPVs of hundreds of mV, as confirmed by our measurements. We therefore analyzed the compatibility between low doping and low defect densities in the perovskite layer and such high SPV values using numerical modelling. It is shown that these high SPV values could originate from electronic processes due to large band offsets in the buried perovskite-SCTL heterojunctions, or at the SCTL - transparent conductive oxide (TCO) buried heterojunction. However, such electronic processes can hardly explain the long SPV persistence after switching off the illumination, which could be a sign that light-induced physicochemical processes are at work.

description: The application of Ge|Si virtual substrates with an ultrathin Ge layer to the development of high efficiency III-V solar cells is analyzed. The potential to achieve high efficiencies in GaInP/GaInAs/Si triple-junction cells, which is affected by the optical absorption in the Ge layer, is theoretically demonstrated under realistic scenarios of Ge|Si substrate characteristics and III-V cell configurations. The first dual-junction GaInAs/Ge|Si III-V cells fabricated on these substrates demonstrate the concept with functional devices and show the route to high efficiency implementations by using appropriate Si substrates and optimized Ge deposition.

description: Plastic production is continuously growing and accumulated in the socioeconomic system. Plastic in the stock has the potential to become plastic waste in the future, contributing to waste generation or secondary plastics supply. This research applied material flow analysis(MFA) which provides one-year snapshot of the system to then build a dynamic MFA model to estimate the future plastic waste change from 1960 to 2040. The results show that around 66.27±15.4 million tonnes(MT) plastic polymers production in the EU, and about 69.99±11.8 MT consumed across packaging(31%), construction(18%), transport(13%), electrical and electronic products(9%), textiles(6%) and other(23%) applications in 2014. The recycling rate was around 38% but only 9% of this was used as secondary plastics to produce new products. According to the stock modelling, total inflows and outflows are expected to increase in the future, which accounts for 178MT inflows and 131MT outflows in 2040. The amounts of in-use stock in this scenario continue increase and reach to 1282MT in 2040. Construction dominates the stock-in-use for a long time due to its long life span. These results highlight the large quantities of plastics have accumulated in the societal stock and leakage to natural systems. This study provides decision-makers an evidence-based model to plan plastic circular economy strategies. Future research is suggested to combine these results of the stock model into different scenarios which can help in gaining insights about possible future outcomes of plastic circular economy strategies in the EU.

description: Several self-consistent models have been proposed, aiming at describing the phase space distribution of stars in globular clusters. This study explores the ability of the recently proposed LIMEPY models (Gieles & Zocchi) to reproduce the dynamical properties of direct N-body models of a cluster in a tidal field, during its entire evolution. These dynamical models include prescriptions for the truncation and the degree of radially-biased anisotropy contained in the system, allowing us to explore the interplay between the role of anisotropy and tides in various stages of the life of star clusters. We show that the amount of anisotropy in an initially tidally underfilling cluster increases in the pre-collapse phase, and then decreases with time, due to the effect of the external tidal field on its spatial truncation. This is reflected in the correspondent model parameters, and the best-fit models reproduce the main properties of the cluster at all stages of its evolution, except for the phases immediately preceding and following core collapse. We also notice that the best-fit LIMEPY models are significantly different from isotropic King models, especially in the first part of the evolution of the cluster. Our results put limits on the amount of radial anisotropy that can be expected for clusters evolving in a tidal field, which is important to understand other factors that could give rise to similar observational signatures, such as the presence of an intermediate-mass black hole.

description: In the framework of the H2020 project ‘RadHard’ we demonstrate for the first time high efficiency triplejunction space solar cells on 200 mm Ge wafers with excellent efficiencies exceeding 30% (AM0, 25°C). Crystal growth of dislocation free germanium ingots with sufficient diameters is achieved and a pilot-line for wafer manufacturing is implemented successfully at UMICORE. The surface quality obtained on the 200 mm wafers is close to the grade of commercially available 150 mm substrates. A comprehensive growth study on different III/V materials comparing MOVPE growth on 150 and 200 mm substrates shows good to excellent workability of the 200 mm substrates at AZUR SPACE. The epitaxy process of the AZUR standard 3G30 triple-junction structure has been performed in an AIXTRON planetary reactor using an industrially feasible MOVPE recipe, whereas due to the wafer format >11% wafer area is treated in a single epitaxial run by using 200 mm instead of 150 mm wafers. For solar cell manufacturing the standard 30.18 cm² cell design is applied, using a cell arrangement that allows the assessment of the epitaxy homogeneity across the 200 mm wafer surface by means of cell performance. Engineering tests are performed on a test coupons built up with these cells verify the device quality. Finally, the growth of solar cell structures on two separate 200 mm Ge substrates and their subsequent merging by the direct semiconductor bonding technology (SBT) is demonstrated, which is known to enable ultra-high efficient tandem solar cells but is cost-intensive when using smaller wafers.

description: Emerging photovoltaic (PV) technologies like organic (OPV) and dye-sensitized (DSC) devices are rapidly evolving and considerable research effort has addressed various approaches to increase their efficiency, reaching in the last years promising values. Examples of large area DSC modules for outdoor installation have been showcased by different manufacturers and proposed for multiple applications. Here we present an indoor calibration of a large area DSC PV device, at standard test conditions (STC), through I-V measurements and the determination of the spectral responsivity following the procedures described in IEC 60891 and 60904 standards. Initial measurements have focused on the analysis of the module time response to light stimulus and on the necessary pre-conditioning step to ensure a reliable calibration at steady state conditions. Then the electrical performance was measured at STC, at irradiances from 100 W/m2 to 1000 W/m2 (at 25 °C) and for temperatures from 10 °C to 50 °C (at 1000 W/m2).

description: We present the study of nineteen low X-ray luminosity galaxy clusters (L$_X \sim$ 0.5--45 $\times$ $10^{43}$ erg s$^{-1}$), selected from the ROSAT Position Sensitive Proportional Counters (PSPC) Pointed Observations (Vikhlinin et al. 1998) and the revised version of Mullis et al. (2003) in the redshift range of 0.16 to 0.7. This is the introductory paper of a series presenting the sample selection, photometric and spectroscopic observations and data reduction. Photometric data in different passbands were taken for eight galaxy clusters at Las Campanas Observatory; three clusters at Cerro Tololo Interamerican Observatory; and eight clusters at the Gemini Observatory. Spectroscopic data were collected for only four galaxy clusters using Gemini telescopes. With the photometry, the galaxies were defined based on the star-galaxy separation taking into account photometric parameters. For each galaxy cluster, the catalogues contain the PSF and aperture magnitudes of galaxies within the 90\% completeness limit. They are used together with structural parameters to study the galaxy morphology and to estimate photometric redshifts. With the spectroscopy, the derived galaxy velocity dispersion of our clusters ranged from 507 km~s$^{-1}$ for [VMF98]022 to 775 km~s$^{-1}$ for [VMF98]097 with signs of substructure. Cluster membership has been extensively discussed taking into account spectroscopic and photometric redshift estimates. In this sense, members are the galaxies within a projected radius of 0.75 Mpc from the X-ray mission peak and with cluster centric velocities smaller than the cluster velocity dispersion or 6000 km~s$^{-1}$, respectively. These results will be used in forthcoming papers to study, among the main topics, the red cluster sequence, blue cloud and green populations; the galaxy luminosity function and cluster dynamics.

description: The reboot after the global Covid-19 crisis will go through the investment of large economic resources around the world. To take advantage of the opportunity to improve the world situation, this money should be invested extensively for the technological and green energy revolution. Photovoltaics is nowadays a mature technology, capable of providing green energy at competitive prices compared to fossil fuels. Regarding manufacturing costs, CdTe thin film devices have a great advantage over traditional crystalline silicon cells, since they can be fabricated in a single production line. Furthermore, CdTe panels nowadays exceed an efficiency of 19 %, close to that of silicon technology. The efficiency improvement of the last few years is mainly due to the introduction of a CdSexTe1-x layer in the absorber. This reduces the band gap increasing the absorption in the long wavelength region. Moreover, it allows a better band alignment with wider band gap buffers, enabling the removal of the CdS window layer. In this work we study a SnO2/CdSexTe1-x/CdTe solar cell where the band gap grading of the absorber has been achieved through an innovative method: the selenization of the CdTe layer.

description: III-V//Si multi-junction solar cells offer a pathway to increase the power conversion efficiency beyond the fundamental Auger limit of silicon single-junctions. In this work we demonstrate how the efficiency of a twoterminal wafer-bonded III-V//Si triple-junction solar cell is increased from 34.1 % to 35.9 % under an AM1.5g spectrum, the highest reported efficiency for silicon based multi-junction solar cell technologies. This improvement was accomplished by two main factors. First, the integration of a GaInAsP absorber in the middle cell increased the open-circuit voltage by 51 mV. Second, a better current matching of all subcells enhanced the short-circuit current by 0.7 mA/cm².

description: We study the predicted rotational evolution of solar-type stars from the pre-main sequence to the solar age with 1D rotating evolutionary models including physical ingredients. We computed rotating evolution models of solar-type stars including an external stellar wind torque and internal transport of angular momentum following the method of Maeder and Zahn with the code STAREVOL. We explored different formalisms and prescriptions available from the literature. We tested the predictions of the models against recent rotational period data from extensive photometric surveys, lithium abundances of solar-mass stars in young clusters, and the helioseismic rotation profile of the Sun. We find a best-matching combination of prescriptions for both internal transport and surface extraction of angular momentum. This combination provides a very good fit to the observed evolution of rotational periods for solar-type stars from early evolution to the age of the Sun. Additionally, we show that fast rotators experience a stronger coupling between their radiative region and the convective envelope. Regardless of the set of prescriptions, however, we cannot simultaneously reproduce surface angular velocity and the internal profile of the Sun or the evolution of lithium abundance. We confirm the idea that additional transport mechanisms must occur in solar-type stars until they reach the age of the Sun. Whether these processes are the same as those needed to explain recent asteroseismic data in more advanced evolutionary phases is still an open question.

description: We propose a scheme to realize a highly efficient solid state source of photon pairs using cavity-assisted stimulated Raman adiabatic passage (STIRAP) in a single quantum dot, where a single photon from pump pulse and two stokes photons from cavity mode drives the Raman transition. The Autler-Townes doublet, generated by using a resonant continuous wave laser between biexciton and exciton states, and two-photon-resonant transition through strongly coupled cavity mode are utilized to facilitate (1+2)type Raman transition in the quantum dot. We show in the case of weak pump although the probability of generating two photons in cavity mode is small without cavity damping but two-photon-resonant emission is enhanced by cavity damping within strong coupling regime. We also discuss spectrum of the generated photon pair and photon-photon correlations in the generated photon pair. The efficiency of two photon source could be more than 80\% in current experimental conditions.

description: Effective logistics chain management has become a potentially valuable way of securing competitive advantage through enhancing operational and improving organizational performances since competition is so high and growing from time to time. This paper by considering this fact and central role of transportation at every logistics activity, performed the study by identifying roles of transportation (connecting, storage and creating time and place utility) and logistics performance dimensions (logistics differentiation, effectiveness and efficiency) in order to see the relationship between transportation and logistics chain performance. The data to conduct the study was collected from 82 staff of the company using questionnaire. the practice of transportation was analyzed using descriptive statistics like mean and standard deviation as per the result weakness observed in areas of timely reply to special enquiry, flexibility and some human and non human factors affecting performance of transportation is identified. The relationships proposed in the framework were tested using Pearson correlation, and the causal relations were analyzed using regression analysis. From the result of the analysis it is concluded that there is strong relationship between role of transportation and Logistics chain performance and between transportation practice and logistics chain performance also the relationship between the roles of transportation and logistics performance dimension is strong. Hence, it is to the benefit of the company to give due emphasis to improving transportation service in order to benefit from better logistics performance Key words: Logistics chain, Transportation, Role

description: This paper introduces a detailed study between carrier lifetime and wafer thickness in Czochralski-grown (Cz) crystalline silicon (c-Si) wafers which will later be processed into solar cells. Wafers are thinned to different thicknesses with a minimum of 54.8 µm via wet chemistry etching as carrier lifetime drops from around 3000 µs to lower than 500 µs. A negative correlation appears between the carrier lifetime and wafer thickness.

description: The general objective of the study was to find out challenges and prospects of Ethiopian cement market. The study has employed exploratory research design since the subject understudy is novel in cement industry. Qualitative research method has been used to collect data. The sampling strategy for the study was non-probability (purposive)sampling based on criteria. Based on their market share and cement production capacity, six cement firms have been selected from the industry.Totally, 6 cement firms' marketing mangers and 9 whole sellers wereselected to conduct the study. The selected cement firms in the industry covers 69% of the total cement production capacity and 85% annual cement market share. In-depth interview has been done to collect data from the marketing managers and whole sellers of the cement firms' understudy. The data has analyzed by using content analysis method. Main findings of the study includes; imbalance between production capacity and cement demand due to enormous cement projection in the country, drop in cement demand due to slow construction boom, marketing mix strategies 4ps and market intermediaries. The prospects of Ethiopian cement market includes;huge number of population and countries fast growth rate, low cement per capita consumption, increased government spending on infrastructure, and availability of rural and urban housing projects. The study has recommended that, the cement market should be regulated in some extent to safeguard the small cement firms, government should plan and execute cement demand simulation mechanisms, and alternative energy sources should be practiced and utilized in cement firms to reduce cement production cost.

description: The catalytic chemical vapor deposition technology (CAT-CVD), also called Hot-Wire CVD (HW- CVD), is a commonly used technique for the production of various thin-film materials in many branches of the thin- film industry. The focus of this work has been placed on the process development of the hydrogenated amorphous silicon thin-film (a-Si:H) deposition used for fabrication of highly efficient heterojunction solar cells with intrinsic thin layer (HIT). The advantages of the HW-CVD technique are high deposition rates and a lack of plasma damage which is a significant feature in the production of the thin-film layers. The main subject of this work is the development of a high-rate dynamic deposition technique, which enables the realization of a process on large area substrates and in roll- to-roll systems.

description: The origin of outflow in narrow-line region (NLR) of active galactic nucleus (AGN) is studied in this paper by focusing on the relationship between the [\ion{O}{3}]$λ$5007 line profile and the hard X-ray (in a bandpass of 2-10 keV) emission from the central SMBH in type-I AGNs. A sample of 47 local X-ray selected type-I AGNs at $z<0.2$ is extracted from the 2XMMi/SDSS DR7 catalog that is originally crossmatched by Pineau et al. The X-ray luminosities in an energy band from 2 to 10keV of these luminous AGNs range from $10^{42}$ to $10^{44}\ \mathrm{erg\ s^{-1}}$. A joint spectral analysis is performed on their optical and X-ray spectra, in which the [\ion{O}{3}] line profile is modeled by a sum of several Gaussian functions to quantify its deviation from a pure Gaussian function. The statistics allows us to identify a moderate correlation with a significance level of 2.78$σ$: luminous AGNs with stronger [\ion{O}{3}] blue asymmetry tend to have steeper hard X-ray spectra. By identifying a role of $L/L_{\mathrm{Edd}}$ on the correlation at a $2-3σ$ significance level in both direct and indirect ways, we argue that the photon index versus asymmetry correlation provides evidence that the AGN's outflow commonly observed in its NLR is related with the accretion process occurring around the central SMBH, which favors the wind/radiation model for the origin of the outflow in luminous AGNs.

description: Optimization of hot zone parts and increasing resistance is the key to increase minority carrier lifetime, thereby, efficiency. In this study, Boron-doped p-type monocrystalline silicon ingots were grown by the Czochralski (CZ) method simply by employing necessary hot zone parts and 28” inch crucibles to obtain higher minority carrier lifetime values. Defects, minority carrier lifetime and resistivity were evaluated for the optimized growing processes. Results revealed that utilization of larger parts for the CZ pullers yielded higher values for the top part of the ingot.

description: The low-lying $M1$-strength of the open-shell nucleus $^{50}$Cr has been studied with the method of nuclear resonance fluorescence up to 9.7 MeV, using bremsstrahlung at the superconducting Darmstadt linear electron accelerator S-DALINAC and Compton backscattered photons at the High Intensity $γ$-ray Source (HI$γ$S) facility between 6 and 9.7 MeV of the initial photon energy. Fifteen $1^{+}$ states have been observed between 3.6 and 9.7 MeV. Following our analysis, the lowest $1^{+}$ state at 3.6 MeV can be considered as an isovector orbital mode with some spin admixture. The obtained results generally match the estimations and trends typical for the scissors-like mode. Detailed calculations within the Skyrme Quasiparticle Random-Phase-Approximation method and the Large-Scale Shell Model justify our conclusions. The calculated distributions of the orbital current for the lowest $1^{+}$-state suggest the schematic view of Lipparini and Stringari (isovector rotation-like oscillations inside the rigid surface) rather than the scissors-like picture of Lo Iudice and Palumbo. The spin M1 resonance is shown to be mainly generated by spin-flip transitions between the orbitals of the $fp$-shell.

description: Questo contributo intende concentrarsi sui tribunali nella loro accezione di spazi deputati all’amministrazione della giustizia a Roma antica, storicizzando la loro evoluzione durante il principato di Augusto. L’obiettivo è quello di far luce su un indicatore specifico, quale la salubrità, che le fonti letterarie menzionano nel ricostruire i segni di trasformazione dei tribunali. Il peso di questo requisito per migliorare i luoghi in cui avvenivano i processi sarà investigato non tanto da una prospettiva ambientale, bensì all’interno di una riflessione sul comfort urbano e le infrastrutture sostenibili durante la transizione tra Repubblica e Impero.

description: In Cz-Si the shape of the crystallization front, which is essentially controlled by the interaction of the various convection phenomena, determines the radial distribution of the crystal properties and is the subject of numerous publications. In our former investigations [1] on the limits of the pull speed in the Czochralski process, we were able to determine a clear influence of an active crystal cooling on the extent of the deflection of the phase boundary in the growing crystal. In order to investigate the influence of the crystal cooling element on the shape of the interface in more detail, two different series of crystal growth experiments were carried out and interpreted with 2D numerical simulations. For this purpose the shapes of the phase boundaries of the grown crystals were made visible by means of LPS measurements and compared with the calculated interface shapes. In one of the two series, the influence of a certain crystal cooling element in connection with the growth configuration was investigated. In the other series, the influence of different crystal cooling elements on the phase boundary was examined. Based on the heat flux balance at the crystallization front, the essential parameters for stable crystal growth conditions were evaluated. For all experiments performed, the cooling rate of the growing crystal in its growth environment were calculated from the point of view of the distribution of intrinsic defects.
