description: The validity of a solar simulator for concentrator PV modules is assessed through a comprehensive characterization of its illumination system: irradiance level and uniformity at the receiver, light collimation and spectral distribution. Methods for adjusting and characterizing the spectrum are described and applied, and a more meaningful way of comparing it with the reference spectrum is proposed, by means of the measurement of component (‘isotype’) solar cells.

description: This work presents a novel triple-renewable energy system (TRES) that is based on integrating the photovoltaic panels (PVPs), conventional solar chimney (CSC), and cooling tower (CT) in one structure. The ultimate objective of the proposed TRES system is to produce electrical power (Pelc), desalinated water (Dw), and if required cooling utilities. The components of the system include a chimney tower, collector, base, PVPs, water pool, bi-directional turbine, and water sprinklers. The TRES system can be operated as CSC during the daytime and CT at night providing 24-h operation. The PVPs were integrated within the structure to increase the Pelc production and enhance the process performance by heating the air inside the system. The TRES structure increased the efficiency to 0.860% in comparison with the CSC (0.313%). The annual Pelc production from the TRES system was found to be 792 MWh compared with only 380 MWh generated by the CSC achieving 2.1 folds overall improvement. The CSC-PV and CT contributed to 47% (494 MWh) and 24% (253 MWh) of the Pelc production, respectively. The annual Dw production was found to be 1.2-fold higher (163,142 tons) higher than the CSC (139,443 tons). The newly developed TRES system offers a great potential to produce Pelc and Dw and save fossil fuel consumption while reducing the emissions of greenhouse gasses (GHGs) to the atmosphere.Other Information Published in: Environmental Science and Pollution Research

description: Background: The low extracellular pH (pHe) of tumors resulting from glycolytic metabolism is a stress factor for the cells independent from concomitant hypoxia. The aim of the study was to analyze the impact of acidic pHe on gene expression on mRNA and protein level in two experimental tumor lines in vitro and in vivo and were compared to hypoxic conditions as well as combined acidosis+hypoxia. Methods: Gene expression was analyzed in AT1 prostate and Walker-256 mammary carcinoma of the rat by Next Generation Sequencing (NGS), qPCR and Western blot. In addition, the impact of acidosis on tumor cell migration, adhesion, proliferation, cell death and mitochondrial activity was analyzed. Results: NGS analyses revealed that 147 genes were uniformly regulated in both cell lines (in vitro) and 79 genes in both experimental tumors after 24 h at low pH. A subset of 25 genes was re-evaluated by qPCR and Western blot. Low pH consistently upregulated Aox1, Gls2, Gstp1, Ikbke, Per3, Pink1, Tlr5, Txnip, Ypel3 or downregulated Acat2, Brip1, Clspn, Dnajc25, Ercc6l, Mmd, Rif1, Zmpste24 whereas hypoxia alone led to a downregulation of most of the genes. Direct incubation at low pH reduced tumor cell adhesion whereas acidic pre-incubation increased the adhesive potential. In both tumor lines acidosis induced a G1-arrest (in vivo) of the cell cycle and a strong increase in necrotic cell death (but not in apoptosis). The mitochondrial O2 consumption increased gradually with decreasing pH. Conclusions: These data show that acidic pHe in tumors plays an important role for gene expression independently from hypoxia. In parallel, acidosis modulates functional properties of tumors relevant for their malignant potential and which might be the result of pH-dependent gene expression.

description: European foulbrood (EFB), caused by Melissococcus plutonius, is a globally distributed bacterial brood disease affecting Apis mellifera larvae. There is some evidence, even if under debate, that spreading of the disease within the colony is prevented by worker bees performing hygienic behaviour, including detection and removal of infected larvae. Olfactory cues (brood pheromones, signature mixtures, diagnostic substances) emitted by infected individuals may play a central role for hygienic bees to initiate the disease-specific behaviour. However, the mechanisms of cue detection and brood removal, causing hygienic behaviour in EFB affected colonies, are poorly understood. Here, coupled gas chromatography-mass spectrometry (GC–MS) was used to detect disease-specific substances, changes in cuticular hydrocarbon (CHC) profiles, and brood ester pheromones (BEPs) of honey bee larvae artificially infected with M. plutonius. Although no diagnostic substances were found in significant quantities, discriminant analysis revealed specific differences in CHC and BEP profiles of infected and healthy larvae. β-Ocimene, a volatile brood pheromone related to starvation and hygienic behaviour, was present in all larvae with highest quantities in healthy young larvae; whereas oleic acid, a non-volatile necromone, was present only in old infected larvae. Furthermore, γ-octalactone (newly discovered in A. mellifera in this study) was detectable in trace amounts only in infected larvae. We propose that the deviation from the olfactory profile of healthy brood is supposed to trigger hygienic behaviour in worker bees. To confirm the relevance of change in the chemical bouquet (CHCs, BEPs, γ-octalactone, etc.), a field colony bioassay is needed, using healthy brood and hygienic bees to determine if bouquet changes elicit hygienic behaviour.

description: Worldwide, the Programme for International Student Assessment (PISA) has emerged as a valid and reliable benchmark for assessing students’ performance and for gaining significant influence over educational policy and decision-making. Since 2001, Qatar has engaged in massive educational reform, with high expectations for improving students’ achievement. Although significant growth has occurred in Qatar’s education system, students’ performance in PISA is still lagging. The purpose of this article is to examine PISA against the backdrop of Qatar’s education system. It addresses PISA’s objectives and limitations and identifies two common factors in high-achieving countries, teachers, and assessment. These factors are analyzed to determine how Qatar is developing in these areas, compared with other nations, raising issues that should be considered when using PISA to create policy. Finally, several recommendations are offered for policy makers.Other Information Published in: PROSPECTS

description: After the 5 years of the field experience in HCPV in Japan, it was found that a new kind of CPV trackers would be required to the application to Japanese market, where the sun is always covered by thin clouds, soil is soft and wind velocity is high. The new HCPV tracker is based on open-loop control equipped with software correction of installation and alignment errors. The correction is based on a liner model. A 2.4 kW prototype was constructed and tested. Based on the successful demonstration of that 2.4 kW system, a 30 kW CPV power plant consist of 6 enlarged trackers is designed. The CPV power plant is scheduled to be finished by December 2008.

description: We report the observation of carrier mediated decrease in the stiffness of crystalline (c)-Si(100) under nanoindentation. The apparent elastic modulii of heavily dopes (1E21 cm-3) p- and n-type c-Si are observed to be lower by 5.-7.5 percent that the estimated value for intrinsic (1E14 cm-3) c-Si. The deviation observed with respect to elastic modulus remarkably matches with the estimated value while considering the electronic elastic strain effect on carrier concentration as an influence of negative pressure coefficient of band gap for Si. The value is predominantly higher than the reported value of a decrease of 1-3 percent in stiffness as an effect of impurity in c-Si.

Solar Cells, Modules and PV Systems for Space Applications

description: 23rd European Photovoltaic Solar Energy Conference and Exhibition, 1-5 September 2008, Valencia, Spain; 762-767
description: A solar array must be able to withstand the hazardous space environment and be able to operate reliably over a long period of time to be considered for space applications. The capability to withstand high voltage operation is another emerging factor required by space solar arrays as power levels continue to increase. The Stretched Lens Array (SLA) uses concentrator technology to offer outstanding measures of performance while at the same time offering protection against radiation, micrometeoroids, and electrostatic discharges common in high voltage operations. Thus it is especially well suited for electric propulsion missions and operation in high radiation environments such as the Van Allen belts or in those found around Jupiter. This paper will describe SLA past testing and flight history along with detailing two future SLA testing opportunities. The SLA is a durable array that can operate in high voltage, high radiation environments.

description: We have proposed a robust, secure and efficient image encryption algorithm based on chaotic maps and algebraic structure. Nowadays, the chaotic cryptosystems gained more attention due to their efficiency, the assurance of robustness and high sensitivity corresponding to initial conditions. In literature, there are many encryption algorithms that can simply guarantees security while the schemes based on chaotic systems only promises the uncertainty, both of them can not encounter the needs of current scenario. To tackle this issue, this article proposed an image encryption algorithm based on Lorenz chaotic system and primitive irreducible polynomial substitution box. First, we have proposed 16 different S-boxes based on projective general linear group and 16 primitive irreducible polynomials of Galois field of order 256, and then utilized these S-boxes with combination of chaotic map in image encryption scheme. Three chaotic sequences can be produced by the disturbed of Lorenz chaotic system corresponding to variables x, y and z. We have constructed a new pseudo random chaotic sequence ki based on x, y and z. The plain image is encrypted by the use of chaotic sequence ki and XOR operation to get a ciphered image. To show the strength of presented image encryption, some renowned analyses are performed.Other Information Published in: Multimedia Tools and Applications

description: The IEA Photovoltaic Power Systems Programme (IEA PVPS) is one of the collaborative R & D agreements established within the IEA and, since 1993, its participants have been conducting a variety of joint projects (tasks) concerning the applications of photovoltaic conversion of solar energy into electricity. IEA PVPS Task 1 has the responsibility to facilitate the exchange and dissemination of information on the technical, economic, environmental and social aspects of photovoltaic power systems. An important deliverable of Task 1 is the annual Trends in photovoltaic applications report[1]. This report gives information on trends in PV power applications in the PVPS member and other countries and is largely based on the information provided in the national survey reports which are produced annually by the 21 participating countries. This paper presents the latest available information from the 2008 round of surveys, compiled and analyzed shortly before the Valencia conference, and includes the topics of market growth, public budgets, the industry supply chain, prices, economic benefits and support initiatives. This information covers calendar year 2007 and is presented in greater detail in the 2008 Trends report.

description: Background Next-generation sequencing technology has allowed for the rapid development of microsatellites, neutral polymorphic markers that can be used for the analysis of population structure. Methods and Results In this study, we performed whole-genome sequencing using the Illumina MiSeq system and de novo assembly to design microsatellite primers for Triops granarius populations in Qatar. The developed microsatellites are suitable for future studies of genetic structuring among geographically isolated freshwater pools. A total of 23 different primer pairs produced typical microsatellite results, with each pair successfully amplified in up to 40 individuals. Only five of the loci produced a significant departure from Hardy-Weinberg equilibrium. Conclusions Some of the underlying mechanisms regarding the few loci that deviated from HWE may be further investigated to determine the source of deviation. As T. granarius is the most widely distributed species of the family, the development of these molecular markers would be useful for conducting population genetics and biogeographical studies broadly.Other Information Published in: Molecular Biology Reports

description: Understanding how species’ thermal limits have evolved across the tree of life is central to predicting species’ responses to climate change. Here, using experimentally-derived estimates of thermal tolerance limits for over 2000 terrestrial and aquatic species, we show that most of the variation in thermal tolerance can be attributed to a combination of adaptation to current climatic extremes, and the existence of evolutionary ‘attractors’ that reflect either boundaries or optima in thermal tolerance limits. Our results also reveal deep-time climate legacies in ectotherms, whereby orders that originated in cold paleoclimates have presently lower cold tolerance limits than those with warm thermal ancestry. Conversely, heat tolerance appears unrelated to climate ancestry. Cold tolerance has evolved more quickly than heat tolerance in endotherms and ectotherms. If the past tempo of evolution for upper thermal limits continues, adaptive responses in thermal limits will have limited potential to rescue the large majority of species given the unprecedented rate of contemporary climate change.

description: For several decades, forming blend and composite of polyaniline (PANI) with insulating polymers has been a widely studied research area because of the potential applications of such blends, which have a unique combination of mechanical properties, the processability of conventional polymers and the electrical property of conducting polymers. The current review paper will emphasize PANI composites or blends with thermosetting polymer matrices. The enhanced electro-mechanical properties of the blends and composites depend on the uniform dispersion of the PANI particle in polymer matrix. Therefore, considerable studies have focused on improving the distribution of PANI particles within the thermoset matrices. In this review paper, all the parameters and conditions that influence the surface morphology and application of PANI thermoset blends and composites will be described systematically. Recent progress on PANI based thermoset system with multifunctional ternary composites research will be highlighted in this paper. Furthermore, encouraging applications of different PANI thermoset composites and blends are discussed, such as flame-retardant materials, lightning damage suppression, metal ion removal, anticorrosive coating, electromagnetic shielding, conductive adhesives, and sensing materials.Other Information Published in: Journal of Polymer Research

is presented. The Rsheet-PL method is suitable for mono- and multi crystalline wafer solar cells. It provides the sheet
resistance with high resolution, in a non-destructive way and without the need for a specific calibration process.
Another benefit of this methodology is its robustness against spatial variations of local diode characteristics. The

description: Carrier density is a frequently examined parameter for silicon material characterisation. Besides the detection of the
minority carrier lifetime under low injection conditions like QSSPC, CDI/ILM, and PL more advanced material
characterisation methods are based on carrier density measurements. Although spatial resolution has been included in many
measurement techniques, the depth dependence of the carrier profiles is typically neglected and homogeneous carrier profiles
are assumed. This assumption, however, does not hold for many practical cases and may introduce significant systematic
errors. In this work, analytical simulations show the expected errors quantitatively. Iron imaging is taken as an example to
demonstrate the magnitude of the systematic error. A correction method is provided which accounts for the inhomogeneous
carrier profiles.

description: Clay minerals and pedogenic metal (oxyhydr)oxides are the most reactive soil mineral constituents controlling the long-term persistence of organic carbon (OC) in terrestrial ecosystems. However, their co-occurrence in most soils complicates direct assessment of their individual contribution to OC persistence. Making use of unique mineralogical combinations in soils located in the East Usambara Mountains of Tanzania, we disentangled the contribution of clay-sized aluminous minerals (kaolinite, gibbsite) and pedogenic Fe (oxyhydr)oxides (predominant goethite and hematite) on OC storage and stabilization under natural forests and croplands. Topsoil samples, varying in contents but not types of aluminous clays and pedogenic Fe (oxyhydr)oxides, were identified by selective extractions, X-ray diffraction, and Mössbauer spectroscopy. Associated abundance of particulate and mineral-associated organic matter (OM) was quantified by density fractionation and their changes during land-use conversion were determined as a measure of OC persistence. Additionally, we assessed the resistance of OC to chemical oxidation as well as microbial decomposition in a 50-day laboratory incubation. We found that the ratio of pedogenic Fe to aluminous clay is more consequential for OC storage and stabilization than their individual contents, despite the fact that Fe (oxyhydr)oxides generally exert a stronger impact on OC than aluminous clays. Conjunction of large amounts of Fe (oxyhydr)oxides with low aluminous clay contents caused the strongest accumulation of mineral-associated OC, a low soil respiration, high OC stability against chemical oxidation, and high OC persistence during land-use change. Our study suggests that certain mineralogical combinations in the humid tropics alleviate OM losses during land conversion because of the strong and selective mineral control on OC stabilization, particular if the weight ratio of pedogenic Fe to aluminous clay exceeds the threshold range of 0.44‒0.56.

description: An overview of the status of the developing PV market in Greece will be presented, in terms of applications to the Regulatory Energy Authority (RAE) and PV systems installed and connected to the grid. As the penetration of PV
systems in the Greek electricity market is going to increase to over 800 MWp by the year 2015 the feed-in tariff contribution collected from the electricity consumers will allegedly increase substantially. An attempt is made for reasonable assumptions according to the international experience and along the lines of the national reports and binding targets of RES introduction and in the future years in Greece. The real value of the PV electricity produced is assessed and the cost–benefit balance is calculated for the large introduction of PV systems until 2020. The economic impact on the average Hellenic household depends on the Feed-in tariff, the cost of electricity production in the country and the PV system cost evolution. The special RES charge is calculated and conclusions will be drawn. Keywords: PV Market, Funding and Incentives, Economic Analysis

description: Synaptic vesicles are storage organelles for neurotransmitters. They pass through a trafficking cycle and fuse with the pre-synaptic membrane when an action potential arrives at the nerve terminal. While molecular components and biophysical parameters of synaptic vesicles have been determined, our knowledge on the protein interactions in their membranes is limited. Here, we apply cross-linking mass spectrometry to study interactions of synaptic vesicle proteins in an unbiased approach without the need for specific antibodies or detergent-solubilisation. Our large-scale analysis delivers a protein network of vesicle sub-populations and functional assemblies including an active and an inactive conformation of the vesicular ATPase complex as well as non-conventional arrangements of the luminal loops of SV2A, Synaptophysin and structurally related proteins. Based on this network, we specifically target Synaptobrevin-2, which connects with many proteins, in different approaches. Our results allow distinction of interactions caused by ‘crowding’ in the vesicle membrane from stable interaction modules.

description: A search for the radiative neutrinoless double electron capture with single \gray\ emission has been performed in $^{58}$Ni. Gamma radiation from a 7286 g nickel sample in natural isotope composition was measured for 58.3 d with an ultra low background HPGe detector in the Felsenkeller underground laboratory in Dresden, Germany. A new lower half-life limit of $2.1 \times 10^{21}$ yr (90% CL) was obtained for this decay mode. This half-life limit is two orders of magnitude higher than the existing limit for $^{58}$Ni and among the best half-life limits for neutrinoless double electron capture decays.

description: Phosphorene, a single atomic layer of black phosphorus, has recently emerged as a new twodimensional (2D) material that holds promise for electronic and photonic technology. Here we experimentally demonstrate that the electronic structure of few-layer phosphorene varies significantly with the number of layers, in good agreement with theoretical predictions. The interband optical transitions cover a wide, technologically important spectrum range from visible to mid-infrared. In addition, we observe strong photoluminescence in few-layer phosphorene at energies that match well with the absorption edge, indicating they are direct bandgap semiconductors. The strongly layer-dependent electronic structure of phosphorene, in combination with its high electrical mobility, gives it distinct advantages over other twodimensional materials in electronic and opto-electronic applications.

description: Parental involvement in dual-earner families is a subject that has been widely studied in the literature in Western contexts. Less attention, however, has been allocated to the challenges that dual-earner families encounter in raising children in Arab Gulf states. This paper study aims to address the following questions: To what extent are dual-earner families involved in their children’s lives? What are the gender differences in parental involvement? This paper employed the 2017 survey data of working Qatari males and females to measure their parental involvement and engagement in family time and childcare. The results highlighted parental factors, work characteristics and social supports as key factors determining the degree of parental involvement. The results also showed the gender differences in parental involvement scores, which comprise several factors, including work demands and time spent with children. Taken together, our findings provide insights allowing suggestions for mechanisms that could generate foundational parental welfare policies for dual-earner families in Qatar and the wider Arab Gulf Region as a whole. Further contributions to this research domain could include studies encompassing a wider scope of geographical locations within the Arab Gulf states using robust experimental investigations.Other Information Published in: Journal of Child and Family Studies

description: Winter oilseed rape (WOSR) is the major oil crop cultivated in Europe and the most important feedstock for biodiesel. Up to 90% of the greenhouse gas (GHG) emissions from biodiesel production can occur during oilseed rape cultivation. Therefore, mitigation strategies are required and need to focus on direct nitrous oxide (N2O) emission as one of the largest GHG contributors in biodiesel production. Earlier studies show that nitrification inhibitors (NIs) can reduce N2O emissions derived from N-fertilization. Since information on the effect of biogas digestates with or without NIs on N2O emissions from WOSR fields is scarce, the aim of this study was to evaluate their effects on N2O emissions, mineral N dynamics, and oil yield in WOSR production fertilized with digestate. The study was conducted at five sites across Germany over three years resulting in 15 full site-years data sets. Across all sites and years, N2O emission from WOSR fertilized with biogas digestate (180 kg NH4+-N ha−1yr−1) ranged between 0.2 and 3.5 kg N2O–N ha−1 yr−1. Due to the reduction of the nitrate concentrations following digestate application, application of NI significantly reduced annual N2O emission by 36%. Our results demonstrate that NI can be an effective measure for reducing N2O emissions from digestate application, but its effectiveness depends on soil and weather conditions, and ultimately on the site-specific potential for N2O production and release. There was no effect of NI application on grain and oil yield.
Why is comfort food comforting? A test of the social surrogacy hypothesis
Creators: name: Coleman, William P.

description: According to the social surrogacy hypothesis (Gabriel et al., 2016), comfort food is comforting in times of social disconnection because it reminds people of close others. While past research has demonstrated that people with a secure attachment style benefit emotionally from and prefer comfort food when feeling socially disconnected (Troisi & Gabriel, 2011; Troisi et al., 2015), it is unclear whether they prefer such foods because they are reminded of close others, or because they prefer familiar objects and experiences, of which comfort food is but an example. To address these competing explanations, in the present study we manipulated participants’ sense of social connection and then had them make choices about food and non-food targets which differed in degree of familiarity. We hypothesized that participants with a secure (vs. insecure) attachment style would prefer more familiar food targets after recalling a rejection experience compared to a frustration or neutral experience, and that this preference would persist relative to familiar non-food targets. However, hierarchical regression analyses showed that while attachment security did not predict preferences for familiar food targets as anticipated, it did predict preferences for fewer familiar non-food targets, especially among participants who recalled a neutral experience. We discuss these findings, the methodological and theoretical limitations, and provide suggestions for future research on the social surrogacy of comfort food.

description: The reactive dicarbonyl metabolite, methylglyoxal (MG), is increased in obesity and diabetes and is implicated in the development of insulin resistance, type 2 diabetes mellitus and vascular complications of diabetes. Dicarbonyl stress is the metabolic state of abnormal high MG concentration. MG is an arginine-directed glycating agent and precursor of the major advanced glycation endproduct, arginine-derived hydroimidazolone MG-H1. MG-H1 is often formed on protein surfaces and an uncharged hydrophobic residue, inducing protein structural distortion and misfolding. Recent studies indicate that dicarbonyl stress in human endothelial cells and fibroblasts in vitro induced a proteomic response consistent with activation of the unfolded protein response (UPR). The response included: increased abundance of heat shock proteins and ubiquitin ligases catalysing the removal of proteins with unshielded surface hydrophobic patches and formation of polyubiquitinated chains to encapsulate misfolded proteins; and increased low grade inflammation. Activation of the UPR is implicated in insulin resistance. An effective strategy to counter increased MG is inducing increased expression of glyoxalase-1 (Glo1). An optimized inducer of Glo1 expression, trans-resveratrol and hesperetin combination, normalized increased MG concentration, corrected insulin resistance and decreased low grade inflammation in overweight and obese subjects. We propose that dicarbonyl stress, through increased formation of MG-glycated proteins, may be an important physiological stimulus of the UPR and Glo1 inducers may provide a route to effective suppression and therapy. With further investigation and validation, this may provide key new insight into physiological activators of the UPR and association with dicarbonyl stress.Other Information Published in: Glycoconjugate Journal

description: Decisive improvements of the CELLO hardware now allow FFT impedance analysis on large area solar
cells of various types. Measuring the frequency response of the short circuit current for several frequencies simultaneously
reduces the measurement time drastically. Fitting of the data to the complete impedance model of a solar cell
allows to determine local solar cell properties like lifetime , back side recombination velocity Sb, and the time constant
related to the Rser CD . Comparison with standard CELLO maps allows to quantify the efficiency losses related
to the identified defect types.

description: There is currently no commonly agreed definition or consistent description of what defines best practice Aboriginal and Torres Strait Islander men’s health program. This lack of clarity, has in various ways, hindered the development of an evidence base to guide services who wish to improve the delivery of care to Aboriginal and Torres Strait Islander men. The aim of this scoping review is to provide a better understanding of the essential and/or common elements of an Aboriginal and Torres Strait Islander men’s health program, by reviewing related program factors including: origins of program design, program governance, program leads/facilitators, program funding, length and frequency of programs, program outcome assessment and program evaluation.

description: In this paper we construct a path integral formulation of quantum mechanics on noncommutative phase-space. We first map the system to an equivalent system on the noncommutative plane. Then by applying the formalism of representing a quantum system in the space of Hilbert-Schmidt operators acting on noncommutative configuration space, the path integral action of a particle is derived. It is observed that the action has a similar form to that of a particle in a magnetic field in the noncommutative plane. From this action the energy spectrum is obtained for the free particle and the harmonic oscillator potential. We also show that the nonlocal nature (in time) of the action yields a second class constrained system from which the noncommutative Heisenberg algebra can be recovered.

description: In a Bayesian context, theoretical parameters are correlated random variables. Then, the constraints on one parameter can be improved by either measuring this parameter more precisely - or by measuring the other parameters more precisely. Especially in the case of many parameters, a lengthy process of guesswork is then needed to determine the most efficient way to improve one parameter's constraints. In this short article, we highlight an extremely simple analytical expression that replaces the guesswork and that facilitates a deeper understanding of optimization with interdependent parameters.

description: This paper aims to understand the impact of big data analytics on the retail supply chain. For doing so, we set our context to select the best big data practices amongst the available alternatives based on retail supply chain performance. We have applied TODIM (an acronym in Portuguese for Interactive Multi-criteria Decision Making) for the selection of the best big data analytics tools among the identified nine practices (data science, neural networks, enterprise resource planning, cloud computing, machine learning, data mining, RFID, Blockchain and IoT and Business intelligence) based on seven supply chain performance criteria (supplier integration, customer integration, cost, capacity utilization, flexibility, demand management, and time and value). One of the intriguing understandings from this paper is that most of the retail firms are in a dilemma between customer loyalty and cost while implementing the big data practices in their organization. This study analyses the dominance of the big data practices at the retail supply chain level. This helps the newly emerging retail firms in evaluating the best big data practice based on the importance and dominance of supply chain performance measures.Other Information Published in: Annals of Operations Research

description: In this paper we present our first results on developing refractive secondary optics for the FLATCON® concentrator. A secondary concept basing on a single refraction is investigated. More specifically, the performance of a lens-shaped secondary in combination with the Fresnel primary lens is studied. In first tests we used secondary lenses which are originally designed for another application. In experiments and simulations these devices turned out to increase the acceptance angle and/or the geometrical concentration factor (Cgeo). In particular, the acceptance angle at Cgeo  385X can be increased from ±0.5° to ±1.1°. Furthermore, an acceptance angle of ±0.6° was determined at Cgeo  1040X. In outdoor experiments we studied the optical gains obtained by the application of the secondary lenses.

description: The main goal of this paper is to put together: a) the Whitham theory applicable to slowly modulated $N$-phase nonlinear wave solutions to the focusing nonlinear Schrödinger (fNLS) equation, and b) the Riemann-Hilbert Problem approach to particular solutions of the fNLS in the semiclassical (small dispersion) limit that develop slowly modulated $N$-phase nonlinear wave in the process of evolution. Both approaches have their own merits and limitations. Understanding of the interrelations between them could prove beneficial for a broad range of problems involving the semiclassical fNLS.
