description:
For bacteria, an intricate coordination between sensing and regulating iron levels and managing oxidative stress is required as their levels are tightly interlinked. While various oxidative stress and heme-based redox sensors have been reported for both pathogenic and non-pathogenic bacteria, the mechanisms governing the modulation of intracellular iron levels in response to changes in redox status remain unclear. In this study, a gene-inactivated strain of mycobacterial sensor kinase PdtaS showed dysregulated expression of genes associated with iron metabolism, including Fe-S clusters, NADH dehydrogenases, and iron uptake. The strain showed poor growth in nutrient-limiting conditions, a defect rescuable by heme but not by Fe3+ supplementation. This observation was associated with the PAS domain of the PdtaS sensor kinase. Biochemical and biophysical experiments established heme-binding to the PAS domain and its inhibitory effect on PdtaS auto-kinase activity, suggesting that the absence of heme induces activation of this sensor kinase. Interestingly, despite having an endogenous heme biosynthetic pathway or even external heme supplementation, the ∆pdtaS mutant exhibited persistent low intracellular iron levels concomitant with elevated oxidative stress. Antioxidant supplementation mitigated growth defects, emphasizing the link between oxidative stress, intracellular iron levels, and PdtaS activity. RNA-IP identified key targets associated with redox homeostasis and iron metabolism as targets of the PdtaR response regulator. The study proposes a novel role for the PdtaS-PdtaR TCS in sensing heme, regulation of intracellular iron levels and redox balance.

description: Thin-film Si solar module production requires a fast wide area tool for layer characteristic
measurement and control. Non-uniformity in layer deposition is expected to induce loss in module power.
Simulations of amorphous Si modules using a two-dimensional model have been used to examine the efficiency loss
associated with non uniformity of large scale monolithically integrated thin film modules. The results indicate that
non uniform deposition significantly lowers the module efficiency, in a magnitude that varies depending on the shape
and orientation of the deposition signature relative to the scribe lines. In order to control the deposition process of
individual layers in layer stacks in thin-film PV modules a wide area metrology tools has been developed and tested.
Example of layers maps obtained during production of Si layers module are shown. Comparisons of layer
characteristics obtained using this tool and values obtained by conventional methods are given to validate the tool
performances.
An implicit midpoint difference scheme for the fractional Ginzburg-Landau equation

Publisher: name: arXiv
Year: 2016
Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: This paper proposes and analyzes an efficient difference scheme for the nonlinear complex Ginzburg-Landau equation involving fractional Laplacian. The scheme is based on the implicit midpoint rule for the temporal discretization and a weighted and shifted Grünwald difference operator for the spatial fractional Laplacian. By virtue of a careful analysis of the difference operator, some useful inequalities with respect to suitable fractional Sobolev norms are established. Then the numerical solution is shown to be bounded, and convergent in the $l^2_h$ norm with the optimal order $O(τ^2+h^2)$ with time step $τ$ and mesh size $h$. The a priori bound as well as the convergence order hold unconditionally, in the sense that no restriction on the time step $τ$ in terms of the mesh size $h$ needs to be assumed. Numerical tests are performed to validate the theoretical results and effectiveness of the scheme.

description: The paper describes the development and application of n-type hydrogenated microcrystalline silicon
oxide (μc-SiOx:H) alloys as window layers in n-side illuminated thin film silicon solar cells with microcrystalline
silicon (μc-Si:H) absorber layers. Optical, electrical and structural properties of μc-SiOx:H films were investigated by
Photothermal Deflection Spectroscopy (PDS), conductivity and Raman scattering measurements. μc-SiOx:H layers
were prepared over a range of carbon dioxide (CO2) flow and film thickness, and the effects on the solar cell
performance were investigated. By optimising the μc-SiOx:H window layer properties, an improved short-circuit
current density of 23.4 mA/cm2 is achieved, leading to an efficiency of 8.0% for 1μm thick absorber layer and Ag
back contact. The correlation between cell performance and reduced reflection in μc-SiOx:H n-i-p solar cells is
discussed. The results are compared to the performance of solar cells prepared with alternative optimised window
layers.

description: Amorphous and microcrystalline silicon solar cells were dynamically deposited with linear plasma
sources operated at 81.36 MHz excitation frequency. In this article the results of dynamically deposited solar cells are
shown. For amorphous silicon single junction solar cells an initial efficiency of about 9.4 % (~ 7 % stable) was
achieved. Microcrystalline silicon solar cells were deposited with 6.35 % initial efficiencies (6.2 % stable). The
substrate velocity could be enhanced to 0.5 m/min for amorphous silicon and up to 0.15 m/min for microcrystalline
silicon without a significant deterioration of the solar cell properties. The deposition of both a-Si:H and μc-Si:H was
very homogeneous with thickness variations less than +/- 5% perpendicular to the movement direction of the
substrate. The dimensions of the linear plasma source are 100x500 mm² which allows for the deposition of 300 mm
wide substrates with the deposition concept tool used in this work.

description: The wine and cork industries are both global in scope. Historically, corks were used to stopper ninety-five percent of wine bottles. Cork production is concentrated in Portugal and Spain. Cork comes from the bark of cork oaks and is harvested in nine-year cycles with individual trees being productive for between 100 and 150 years. Hence, the supply curve in the cork industry is highly inelastic. An increase in the demand for wine in North America and the antipodes as tastes changed to include wine in alcohol consumption led to an increase in the derived demand for corks – which was difficult to accommodate given inelastic supply. This led to a search for substitutes for corks and a change in the narrative to convince consumers that wine sealed with screw tops was not of low quality. Over time, this led to the gradual acceptance of screw tops (and other alternatives to corks) by wineries and consumers. The switch was most dramatic in Australia and New Zealand. The global share of corks declined dramatically. In reaction, the cork industry began to actively try and reverse the trend to screw tops. It invested in improving the quality of cork and in changing the narrative so that consumers would associate corks with being the sustainable source in wine stoppers. After forty years of disequilibrium, a new equilibrium may be being approached.
P-splines with derivative based penalties and tensor product smoothing of unevenly distributed data

Year: 2016
Subjects: subject: Computation (stat.CO)
subject: FOS: Computer and information sciences

description: The P-splines of Eilers and Marx (1996) combine a B-spline basis with a discrete quadratic penalty on the basis coefficients, to produce a reduced rank spline like smoother. P-splines have three properties that make them very popular as reduced rank smoothers: i) the basis and the penalty are sparse, enabling efficient computation, especially for Bayesian stochastic simulation; ii) it is possible to flexibly `mix-and-match' the order of B-spline basis and penalty, rather than the order of penalty controlling the order of the basis as in spline smoothing; iii) it is very easy to set up the B-spline basis functions and penalties. The discrete penalties are somewhat less interpretable in terms of function shape than the traditional derivative based spline penalties, but tend towards penalties proportional to traditional spline penalties in the limit of large basis size. However part of the point of P-splines is not to use a large basis size. In addition the spline basis functions arise from solving functional optimization problems involving derivative based penalties, so moving to discrete penalties for smoothing may not always be desirable. The purpose of this note is to point out that the three properties of basis-penalty sparsity, mix-and-match penalization and ease of setup are readily obtainable with B-splines subject to derivative based penalization. The penalty setup typically requires a few lines of code, rather than the two lines typically required for P-splines, but this one off disadvantage seems to be the only one associated with using derivative based penalties. As an example application, it is shown how basis-penalty sparsity enables efficient computation with tensor product smoothers of scattered data.

description: Thin-film silicon solar cells are known to be able to improve the conversion efficiency of multijunction
solar cells with different band gap. Amorphous silicon (a-Si) and microcrystalline silicon (mc-Si) double
junction thin-film solar cells can be obtained conversion efficiency of more than 9% and be significantly improved
conversion efficiency compared to a-Si single junction thin-film solar cells. Last year, ULVAC released the new PECVD
system named CIM-1400 for mc-Si deposition with the concept of high-throughput and low-cost production,
and developed a-Si/mc-Si tandem turnkey line. ULVAC realized tandem junction solar module with initial power
output of 150W and stabilized power output of 135W produced with CIM-1400. ULVAC introduces its further
approach to efficiency improvement of thin-film solar cell. Topics to be introduced are ULVAC’s approach to
stabilized output 145W on commercial production basis, film configuration of a-Si/mc-Si tandem junction solar
module and optimization results with a-Si deposition system (CCV-1400) and CIM-1400 as well as development

description: The treatment of angles within the SI is anomalous compared with other quantities, and there is a case for removing this anomaly by declaring plane angle to be an additional base quantity within the system. It is shown that this could bring several benefits in terms of treating angle on an equal basis with other metrics, removing potentially harmful ambiguities, and bringing SI units more in line with concepts in basic physics, but at the expense of significant upheaval to familiar equations within mathematics and physics. This paper sets out the most important of these changes so that an alternative unit system containing angle as a base quantity can be seen in the round, irrespective of whether it is ever widely adopted. The alternative formulas and units can be treated as the underlying, more general equations of mathematical physics, independent of the units used for angle, which are conventionally simplified by implicitly assuming that the unit used for angle is the radian.

Markets for Large-scale PV

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 4697-4702
description: Photovoltaic (PV) is one of the fastest growing electricity generation technologies in the world.
Average annual growth rates of global PV-installations have reached around 45% for the last 15 years, which
triggered a fast and ongoing reduction of production cost in PV industry. The presented work aims at consolidating
historical price and cost information, deriving refined learning curves for PV modules and systems, and analysing the
main factors of learning. For c-Si modules a valid learning rate of 17% is found based on a meta-analysis of various
studies. In early years, even a learning rate of 30% is observed. As an example for thin-film PV, CdTe module cost
reduce by 16% as the cumulated production output doubles. Interestingly, efficiency improvements contribute only in
second order to the overall cost reduction for both technologies, emphasising the relevance of production excellence
and economies of scale. On PV system level, a cost reduction of 14% per doubling of cumulated installed capacity is
derived. Finally, a sensitivity analysis reveals that learning rate variations are only of minor influence on the overall
global PV market potential.
Charge Transfer in Ultracold Rydberg-Ground State Atomic Collisions

description: In excited molecules, the interaction between the covalent Rydberg and ion-pair channels forms a unique class of excited Rydberg states, in which the infinite manifold of vibrational levels are the equivalent of atomic Rydberg states with a heavy electron mass. Production of the ion pair states usually requires excitation through one or several interacting Rydberg states; these interacting channels are pathways for loss of flux, diminishing the rate of ion pair production. Here, we develop an analytical, asymptotic charge transfer model for the interaction between ultracold Rydberg molecular states, and employ this method to demonstrate the utility of off-resonant field control over the ion pair formation, with near unity efficiency.

description: We present results from a study of the dense circum-nuclear molecular gas of starburst galaxies. The study aims to investigate the interplay between starbursts, active galactic nuclei and molecular gas. We characterise the dense gas traced by HCN, HCO$^{+}$ and HNC and examine its kinematics in the circum-nuclear regions of nine starburst galaxies observed with the Australia Telescope Compact Array. We detect HCN (1$-$0) and HCO$^{+}$ (1$-$0) in seven of the nine galaxies and HNC (1$-$0) in four. Approximately 7 arcsec resolution maps of the circum-nuclear molecular gas are presented. The velocity integrated intensity ratios, HCO$^{+}$ (1$-$0)/HCN (1$-$0) and HNC (1$-$0)/HCN (1$-$0), are calculated. Using these integrated intensity ratios and spatial intensity ratio maps we identify photon dominated regions (PDRs) in NGC 1097, NGC 1365 and NGC 1808. We find no galaxy which shows the PDR signature in only one part of the observed nuclear region. We also observe unusually strong HNC emission in NGC 5236, but it is not strong enough to be consistent with X-ray dominated region (XDR) chemistry. Rotation curves are derived for five of the galaxies and dynamical mass estimates of the inner regions of three of the galaxies are made.

description: A new measurement technology for automated long term measurement evaluations of
photovoltaic (PV) modules has been invented by IWES. The measuring card ISET-mpp meter (Figure 1)
not only allows the measurement of the main module parameters but also enables the complete I-V
characteristics of the modules to be measured. Especially for newly developed modules this approach
offers great potential for performance-tests, derivation of model parameters and new model equations. By
using standardized communication commands it is possible to include the measuring board in a data
acquisition system. Thus long-term measurements of PV modules in different operating modes and in
different environments become possible. The I-V curves of the modules can be determined at specified
intervals, or initiated by a trigger signal. Hereby for example, the influence of various weather conditions
and shadowing situations to the module performance can be assessed. The measurement results can be
sent via a serial port to a PC for further data processing.

description: We perform hole burning with a low drift stabilized laser within the zero phonon line of the 4f-5d transition in Ce$^{3+}$:Y$_2$SiO$_5$ at 2K. The narrowest spectral holes appear for small applied magnetic fields and are $6\pm4$ MHz wide (FWHM). This puts an upper bound on the homogeneous linewidth of the transition to $3\pm2$ MHz, which is close to lifetime limited. The spin level relaxation time is measured to $72\pm21$ ms with a magnetic field of 10 mT. A slow permanent hole burning mechanism is observed. If the excitation frequency is not changed the fluorescence intensity is reduced by more than 50$\%$ after a couple of minutes of continuous excitation. The spectral hole created by the permanent hole burning has a width in the tens of MHz range, which indicates that a trapping mechanism occurs via the 5d-state.

description: Impurities such as oxygen, carbon, iron and chromium in multicrystalline silicon for solar cells can
occur in high concentrations. Their impact on the efficiency depends on the state in which these defects are present.
A large fraction of these elements are bound at structural defects such as dislocations, grain boundaries or
precipitates. We investigated the interaction of these impurities with dislocations and precipitates and the effect on the
diffusion length of minority carriers. The method we applied was the surface photo voltage technique with a high
lateral resolution. One of the main result is that dislocation networks cannot only reduce the interstitial iron
concentration but can also enhance the local impurity concentrations. Also SiC filaments can be responsible for a
drastically reduction of interstitial iron concentration.

description: For the measurement of tandem cells under a sun simulator, the spectral mismatch correction of the short
circuit current to the AM 1.5 standard spectrum cannot be calculated as for single junction cells. Therefore the power
determination of multiple junction cells and modules underlies considerable additional uncertainties. The measurement
tolerance depends not only on the spectrum of the sun simulator and the spectral response of the test and the reference cell,
but also on the degree of the blocking ability of the tandem cell’s limiting junction. In this work, the influence of the
limiting junction on the spectral mismatch of sun simulator measurement of the power of tandem modules is studied as a
function of their reverse currents. In consequence, the error bar is also a function of the individual tandem cell module
under test, even if the spectral responses were assumed as fixed. In this paper a μ-morph tandem cell is modelled with two
filtered crystalline cells. An upper limit for the additional error bar from the tandem problem is estimated on the basis of
the given spectral quality of the sun simulator spectrum and the reverse current characteristics of the module.

description: This report provides an overall look at the Open Studios that were organised as part of the project. They constitute the essential co-creation step in the RESISTIRÉ process, with results from the consecutive research cycles (WP2-4) being interpreted in this multidisciplinary format. The Open Studios are action-oriented, which means that their ultimate output consists of ideas for concrete action, input for recommendations to reshape policies, and unanswered questions (missing insights or knowledge) that can form the foundation of a future research agenda.
 In total, twelve Open Studios were organised over the three cycles of the project, with a mix of participants from the consortium and invited participants. Each Open Studio (OS) had a different thematic focus that reflected important topics that came up in the research. For two days, participants went through a creative process inspired by better stories and by personas that were prepared based on results of the research activities of the project. The overall result was a total of 76 action-ideas that were further used and developed in the RESISTIRÉ project to: Formulate recommendations towards different target groups including policymakers, civil society organisations (including NGOs), employers, and other kinds of stakeholders. Launch pilot actions that tested and demonstrated the potential of innovative approaches Feed the research agenda of RESISTIRÉ, which was promoted to research funding organisations. While the Open Studios generally proved to be a very successful method of translating the research insights into ideas for concrete action, there are still a number of important lessons that were learned throughout the three cycles that can help improve the Open Studio methodology. These are detailed near the end of the report and will serve to finetune the Open Studio concept for use in future projects.

PV Programmes and Policies

description: The recent growth of photovoltaic electricity generation, despite its high levelized costs, was
accompanied by strong national support policies because of its environmental benefits compared with conventional
energy sources. Thus, many countries have set targets for PV deployment. The possibility to achieve them at a lower
cost has now become a central issue, making it necessary to examine the efficiency of the instruments used to
promote PV. First, the mechanisms of PV systems development are described since demand and supply are acting on
the reduction cost of PV systems. On the one hand, subsidies for R&D could be delivered. This would lead to
decrease the PV costs. On the other hand, support could be provided through grants for investment in order to boost
the demand for PV systems. By stimulating the demand, we expect that the cost will decrease due to the learning-bydoing
effect. Then, the public support for PV is assessed for seven representative countries. Based on the financial
evaluations of PV supports, the performances of these policies are compared from the different states of PV
development in each country. The main conclusion is that it is necessary to have a well-planed policy and not an undergone one.

description: One type of hexagonal polytype films of nanocrystalline silicon carbide were prepared by PECVD
technology in capacitively parallel plate plasma reactor, where both silane and methane were introduced into the
plasma reactor. The thin films of SiC, which is a wide band-gap semiconductive material, have many practical
applications due to its high radiation hardness, thermal conductivity, high breakdown field and high operating
frequency. Recently, amorphous SiC has found application as potential alternative to SiNx and SiOx passivation
layers of solar cells. Properties of hydrogenated amorphous silicon carbide films prepared by plasma enhanced
chemical vapour deposition (PECVD) were studied by electrical measurement. Forward and reverse currentvoltage
(IV) characteristics and dielectric response (Au (Al) – SiC(N)/Si–Al structures) are shown in this paper.

Elkem Solar Silicon® (ESSTM) and 50% non-compensated polysilicon is studied. Minority carrier lifetimes are measured
using QssPC calibrated photoluminescence imaging and illumination with 1 Sun is used to induce the degradation. It has
previously been shown than the degradation in compensated silicon depends on the net doping. Light induced
degradation can therefore be reduced by decreasing the net doping. Lifetimes in Cz-wafers are improved despite an
increase in the mix-in ratio of the compensated Elkem Solar Silicon®. Beneficial effects of compensation are seen in ptype
wafers resulting in increased lifetimes. Degradation is observed also in the n-type wafers from 50% ESSTM.

The unique programmable illumination scheme and inductive coupling techniques of the transformer enable a single

description: De Haas-van Alphen oscillations of the organic metal \k{appa}-(ET) 2 Cu(SCN) 2 have been measured up to 55 T at liquid helium temperatures. The Fermi surface of this charge transfer salt is a textbook example of linear chain of orbits coupled by magnetic breakdown. Accordingly, the oscillation spectrum is composed of linear combinations of the frequencies linked to the $α$ and magnetic breakdown-induced $β$ orbits. The field and temperature dependence of all the observed Fourier components, in particular the "forbidden frequency" $β$ -- $α$ which cannot correspond to a classical orbit, are quantitatively accounted for by analytical calculations based on a second order development of the free energy, i.e. beyond the first order Lifshitz-Kosevich formula.

description: We explain the M-sigma relation between the mass of super massive black holes in galaxies and the velocity dispersions of their bulges in the scalar field or the Bose-Einstein condensate dark matter model. The gravity of the central black holes changes boundary conditions of the scalar field at the galactic centers. Owing to the wave nature of the dark matter this significantly changes the galactic halo profiles even though the black holes are much lighter than the bulges. As a result the heavier the black holes are, the more compact the bulges are, and hence the larger the velocity dispersions are. This tendency is verified by a numerical study. The M-sigma relation is well reproduced with the dark matter particle mass $m\simeq 5\times 10^{-22} eV$.

description: Multicrystalline silicon has a share of approximately 50% in photovoltaic energy conversion. The
multicrystalline structure of silicon has an influence on the efficiency of solar cells produced with this material. The
aim of the present work is to summarize and evaluate different methods to characterize grain size distribution of
multicrystalline silicon. The most common methods, the intercept and planimetric methods used in metallography are
investigated. As a result of this investigation the circular intercept method is suggested as preferred method. For
application of the preferred method a multicrystalline silicon block was crystallized and characterized at the SIMTEC
laboratory of Fraunhofer ISE. Intercept length as a measure for grain size distribution was measured at several
positions within this multicrystalline silicon block.

description: The challenge in designing a solar charge controller is to maximize the efficiency of the energy
transfer from the module to the battery. There are many sophisticated and expensive microprocessor-based controllers
on the market, which offer advanced matching techniques. However, due to simplicity, reliability and competitive
price, analogue shunt- and series-type controllers are still preferred for some installations. Design of such a controller
for a 6V photovoltaic system raises some problems, which do not exist e.g. in 12V or 24V installations. That’s why
such solutions, indisputably wanted, are rather completely not available on the market. An analogue controller
usually requires a blocking diode, which prevents the battery from being discharged by the module. The voltage drop
across commonly used Schottky diodes is typically about 600mV and more. Thus, in a 6V system such diode would
dissipate at least 10% of the power from the PV module. An innovative approach replaces the diode with a MOSFET
showing very little on-resistance, which can reduce the voltage drop to less than 100mV for typical currents.
Specialized circuitry is added to sense the source-drain voltage and drive the MOSFET to act like an almost ideal
diode. This solution significantly increases both efficiency and reliability of the controller. Designing a charge
controller for 6V PV systems also requires careful choice of op-amp supply voltage and MOSFETs, which will
operate at lower gate-source voltages than in controllers destined for higher-voltage systems. Attractive employment
of much more convenient conventional semiconductors needs introducing complicated charge-pumps. Special
requirements must deal with the controller’s configuration, length and cross-section of conducting paths due to
voltage drops, so significant in the low 6V circuitry.

description: Using the measurements collected at a number of known locations by a moving binary sensor, characterised by an unknown threshold, the problem is to estimate the parameters of a biochemical source, continuously releasing material into the atmosphere. The solution is formulated in the Bayesian framework using a dispersion model of Poisson distributed particle encounters in a turbulent flow. The method is implemented using the importance sampling technique and successfully validated with three experimental datasets under different wind conditions.

description: INES-CEA, TTA, SAFT, ENERSYS and MAXWELL have taken part to a project cofinanced by the
European Commission in order to develop an inverter including an innovative storage function, dedicated to the injection
of photovoltaic energy into low voltage grids, with special features so that the mutual impacts between the grid and the
PV system are minimised, the system provides grid support on demand, the performance of this PV system is increased
and the end user is protected against poor power quality and outages of the grid.
The article describes the electrical architecture of the system and the individual components. It also presents the main
results of the tests on the storage system and inverter, and the field validation of the whole system.
Storage systems showed their ability to undergo typical daily charge/discharge cycles and in particular withstand peak
power pulses. The field tests of the system validated the behaviour in case of voltage sag and grid interruption, and
showed the steady supply of electricity to the end-user.
SUSTAINABLE PROCUREMENT IN THE AGRICULTURAL SECTOR: A COMESA PERSPECTIVE

Publisher: name: Zenodo
Year: 2024

description: This paper examines the current state of sustainable procurement practices in the agricultural sector within the Common Market for Eastern and Southern Africa (COMESA) region from July 2020 to June 2024. It explores how these practices have evolved and their impact on food security, environmental sustainability, and social equity. The study identifies key challenges, including economic barriers, infrastructure limitations, and regulatory inconsistencies, which have hindered the widespread adoption of sustainable procurement. Despite these challenges, significant progress has been made, particularly in the integration of sustainability into procurement policies and the adoption of technological innovations such as e-procurement and block chain.

The research also highlights the positive outcomes of sustainable procurement, such as improved agricultural productivity, reduced environmental degradation, and increased social inclusion. Notably, the adoption of sustainable practices has led to a 12% improvement in soil health, a 10% increase in water use efficiency, and a 15% rise in employment opportunities for women and youth in the agricultural supply chain. Through a mixed-methods approach, including qualitative case studies and quantitative data analysis, the paper offers a comprehensive evaluation of the effectiveness of sustainable procurement in enhancing food security and reducing the ecological footprint of agricultural activities in COMESA. It concludes with policy recommendations aimed at further integrating sustainability into procurement processes, enhancing regional cooperation, and investing in capacity building for procurement professionals. The findings underscore the importance of continued efforts towards sustainable procurement to achieve long-term agricultural sustainability and resilience in the region.
