description: Various manufacturers have claimed much higher kWh/kWp energy yields (up to 30% better) for their products than
those of their competitors or other technologies.
Some recent independent comparisons [1][2][3][4] have shown much more similar kWh/kWp (often within an
experimental error of ±4-5%) for different module technologies when the correctly declared stabilised Pmax values are used
without a systematic bias towards one manufacturer or technology.
A selection of parameters that differentiate PV technologies by more than ±4-5% have been listed and quantified.
Errors have been found in the kWh/kWp modelling of some sizing programs – their PV databases do not always match
the manufacturers’ measurements for thermal coefficients and low light efficiency changes LLEC (=Eff.@200 /Eff.@1000
W/m²-1) which are measured to international standards such as EN 50380[5] and EN 61215[6].

description: Ten to twenty percent of pregnancies end in miscarriage with eighty percent of pregnancy loss occurring during the first trimester. Because we lack a complete understanding of the environment within the oviduct (Fallopian tube in humans) and its role in regulating early pregnancy, it is difficult to provide diagnostic tools for oviductal origin of early pregnancy loss. It is well established that estrogen (E2) and progesterone (P4) cause biochemical and histological changes in the uterus. However, it is not completely understood how E2 and P4 regulate the oviductal environment in vivo. In this study, we assessed the effect of E2 and P4 on each oviductal cell type, using an ovariectomized-hormone-replacement mouse model and single-cell RNA-sequencing (scRNA-seq). We found that each cell type in the oviduct responded to E2 and P4 distinctively, especially ciliated and secretory epithelial cells. Additionally, we found that epithelial/muscle progesterone receptor (PGR) expression and E2 target gene, insulin-like growth factor 1 (Igf1), are required in the oviduct for normal female fertility and regulates preimplantation embryo development and transport to the uterus. These findings shed light on the roles of E2 and P4 signaling in the oviduct and offer potential applications for women’s reproductive health, infertility, contraception and diagnostic tools of early pregnancy loss.

description: Background: Exercise in humans augments the mobilization of circulating hematopoietic progenitor cells (CD34+) from the bone marrow. We investigated the effect of inflammation on erythroid marrow activity by mobilization of erythroid progenitor cells (EPs) along with soluble markers of erythropoiesis. Methods: Ten healthy athletes who participated in an ultradistance foot race participated in the study. Peripheral blood mononuclear cells were isolated, before (phase I), at the end (phase II), and at 48 h post-race (phase III). EPs were detected as burst colony forming units (BFU-e) and colonies were scored at day 14. Markers of inflammation (C-reactive protein, serum amyloid-A, interleukin-6, ferritin and S100B) and bone marrow activity (erythropoietin, soluble transferrin receptor and lipocalin-2) were assessed. Results: An approximately three-fold decrease in BFU-e number was observed at phase II. sTfR concentrations were also decreased at phase II and remained decreased at phase III. However, EPO and lipocalin-2 concentrations reached a maximum value at phase II, with a tendency to decrease at phase III. Conclusions: These findings indicate that exercise-induced inflammation modulates bone marrow homeostasis leading to an increase in leukocyte turnover and a decrease in erythroid compartment. It appears that lipocalin-2 is the main factor that regulates the production and mobilization of EPs. Clin Chem Lab Med 2010;48:199–203.

description: A new free-form XR Köhler concentrator is presented that combines high geometric concentration, high acceptance angle and high irradiance uniformity on the solar cell. This is achieved by modifying the optical surfaces to produce Köhler integration. Although the new optical surfaces (that is, the ones including Köhler integration) behave optically quite different from the ones that do not integrate, but from the macroscopic point of view they are very similar to them. This means that they can be manufactured with the same techniques (typically plastic injection molding or glass molding) and that their production cost is the same i.e., with a high potential for low cost and high optical efficiency.
The present approach is completely new and allows keeping the acceptance angle at high values and the concentration factor without increasing the number of optical elements. The simulated optical performance of a Köhler integrating solar concentrator is presented. This concept is the first design combining non flat array of Köhler integrators with concentration optics.

description: The study of sensitive parameters for the life cycle analysis (LCA) of PV system showed that irradiation intensity will bring the biggest variation on environmental impact when considering regions with large difference in solar irradiation level. For example, in France a system installed in the northern region will produce
electricity with more than a 100% of the impact of a southern system. Other important factors are the lifetime of the system and the associated electricity use for the different components needed for the PV system. They can bring up
to 35% of variation in the production of CO2 gas and primary non-renewable energy use. This study has been developed within Espace-PV project and results have been analyzed and compared with the EcoInvent database. These results are provided for a 3 kWp multicrystalline grid connected system integrated in a slanted roof with near optimal inclination.

description: As the worldwide demand on higher concentration ratio of HCPV system increases, technological difficulties has increased, especially when larger solar cells are adopted. Characteristics as cell attach, soldering void, carrier type, heat dissipation, light homogenization and assembly tolerance are some of the crucial focuses in design. In this study, we investigate these effects on HCPV performance; an optimal design is suggested accordingly. The geometric concentration ratio is 900x and the cell is 10mmx10mm GaInP/GaAs/Ge triple-junction. Efficiency in the field test is measured. Reliability is tested according to IEC 62108 standard.
Dual Field Theories of Quantum Computation

description: Given two quantum states of N q-bits we are interested to find the shortest quantum circuit consisting of only one- and two- q-bit gates that would transfer one state into another. We call it the quantum maze problem for the reasons described in the paper. We argue that in a large N limit the quantum maze problem is equivalent to the problem of finding a semiclassical trajectory of some lattice field theory (the dual theory) on an N+1 dimensional space-time with geometrically flat, but topologically compact spatial slices. The spatial fundamental domain is an N dimensional hyper-rhombohedron, and the temporal direction describes transitions from an arbitrary initial state to an arbitrary target state. We first consider a complex Klein-Gordon field theory and argue that it can only be used to study the shortest quantum circuits which do not involve generators composed of tensor products of multiple Pauli Z matrices. Since such situation is not generic we call it the Z-problem. On the dual field theory side the Z-problem corresponds to massless excitations of the phase (Goldstone modes) that we attempt to fix using Higgs mechanism. The simplest dual theory which does not suffer from the massless excitation (or from the Z-problem) is the Abelian-Higgs model which we argue can be used for finding the shortest quantum circuits. Since every trajectory of the field theory is mapped directly to a quantum circuit, the shortest quantum circuits are identified with semiclassical trajectories. We also discuss the complexity of an actual algorithm that uses a dual theory prospective for solving the quantum maze problem and compare it with a geometric approach. We argue that it might be possible to solve the problem in sub-exponential time in 2^N, but for that we must consider the Klein-Gordon theory on curved spatial geometry and/or more complicated (than N-torus) topology.

See Dickinson, 2003: 490, and Boles, 2007: 433–434. HOLOTYPE: AMNH 302921, adult male, collected on Mt. Derimapa, 5000 ft, Gebroeders Range, 03.40S, 135.55E (USBGN, 1943), Kobowre (5 Weyland) Mountains, Papua Province, Indonesia, on 24 June 1930, by Frederick Shaw Mayer (no. 42). COMMENTS: In the original description, male number 42 from Mt. Derimapa was designated as the holotype. This specimen bears only an AMNH type label, which was incorrectly marked ‘‘ syntype.’’ A second AMNH type label has been added, indicating that it is a holotype. Shaw Mayer’s collecting in the Gebroeders was supported jointly by Leonard C. Sanford for AMNH and Walter Rothschild and was to be divided between the two museums. However, before this division occurred, Rothschild sold his collection to AMNH and Shaw Mayer’s specimens all came directly to AMNH. Rothschild’s type series comprised two males from Mt. Derimapa and one female from the Siriwo River. The two paratypes are: AMNH 302922 (Shaw Mayer no. 83), male, Mt. Derimapa, 28 June 1930; AMNH 302923 (4), female, Siriwo River, 30 miles above mouth, 9 June 1930.

description: We introduce the notion of a cut cellular surface (CCS), being a surface with boundary, which is cut in a specified way to be represented in the plane, and is composed of 0-, 1- and 2-cells. We obtain invariants of CCS's under Pachner-like moves on the cellular structure, by counting colourings of the 1-cells with elements of a finite group, subject to a "flatness" condition for each 2-cell. These invariants are also described in a TQFT setting, which is not the same as the usual 2-dimensional TQFT framework. We study the properties of functions which arise in this context, associated to the disk, the cylinder and the pants surface, and derive general properties of these functions from topology, including properties which come from invariance under the Hatcher-Thurston moves on pants decompositions.

description: The Darriwilian stromatoporoid assemblages of North China represent a critical stage in early stromatoporoid development across the peri-Gondwanan regions, reaching their highest generic diversity than elsewhere as part of the Great Ordovician Biodiversification Event. We describe four labechiid stromatoporoid species, Labechia variabilis Yabe & Sugiyama, 1930, Labechiella mingshankouensis (Ozaki, 1938), Thamnobeatricea suxianensis (Dong, 1982), and Sinodictyon columnare Yabe & Sugiyama, 1930 from the Middle Ordovician Machiakou Formation in the Xiaonanhai section near Anyang City in northern Henan Province of China. The conodont Plectodina onychodonta occurs in association with these labechiids, implying a middle to late Darriwilian age. This assemblage extends the stratigraphic range of early stromatoporoids in North China to as early as the middle Darriwilian, thus slightly older than the previously known late Darriwilian earliest records. Mutual encrustations of Labechia variabilis and Labechiella mingshankouensis in the present assemblage constructed a microbioherm, together with unidentified tubular organisms, Ortonella-like calcimicrobes, a tubeworm-like organism, and borings. The assemblages of the Darriwilian labechiid stromatoporoids vary from place to place palaeogeographically in the shallow epicontinental marine environment of North China, i.e., in a patchy manner. The significant diversification of Darriwilian labechiid stromatoporoids in North China was likely promoted by a combination of environmental and ecological factors, which include: (1) the occurrence of a very shallow epicontinental marine environment, (2) a possible increase in the carbonate saturation state in seawater, (3) favourable seawater temperature for stromatoporoids during the Middle Ordovician and (4) the scarcity of bryozoans and corals as ecological competitors in North China.

description: Humans promote and inhibit other species on the urban landscape, shaping biodiversity patterns. Institutional racism may underlie the distribution of urban species by creating disproportionate resources in space and time. Here, we examine whether present-day street tree occupancy, diversity, and composition in Baltimore, MD, USA, neighborhoods reflect their 1937 classification into grades of loan risk—from most desirable (A = green) to least desirable (D = “redlined”)—using racially discriminatory criteria. We find that neighborhoods that were redlined have consistently lower street tree α-diversity and are nine times less likely to have large (old) trees occupying a viable planting site. Simultaneously, redlined neighborhoods were locations of recent tree planting activities, with a high occupancy rate of small (young) trees. However, the community composition of these young trees exhibited lower species turnover and reordering across neighborhoods compared to those in higher grades, due to heavy reliance on a single tree species. Overall, while the negative effects of redlining remain detectable in present-day street tree communities, there are clear signs of recent investment. A strategy of planting diverse tree cohorts paired with investments in site rehabilitation and maintenance may be necessary if cities wish to overcome ecological feedbacks associated with legacies of environmental injustice.

Making use of the monotone Galois connection induced by the pattern avoidance relation, we characterize the permutation groups that arise via pattern avoidance as automorphism groups of relations of a certain special form. We also investigate a related monotone Galois connection for permutation groups and describe its closed sets and kernels as automorphism groups of relations.

description: Now-a-days, sustainable energy issues are mainly addressed to the universities and research centers. On the other hand, applied research is implementing fast in companies and the labor market is expanding, needing trained people, at different education levels, with mentality, knowledge and skills shaped on sustainable processes and products. There is a logical link among the portfolio of skills of the high school graduates and the level of academic training; fast progress requires the re-orientation of the high school curricula according to the demands. This is the reason why teacher education centers had recognized both the need for education on sustainable energy and had welcomed this topic as part of the education strategy via cross-curricular subjects. This is the reason why, a transnational partnership developed a Socrates-Comenius 2.1. project, supporting in-service training on sustainable energy, at European level. The paper presents the development of the SEE EU-Tool project, which develops the frame and the instruments for training the teachers to implement the basic concepts of sustainable energy, especially renewable energy systems, at high school level.

description: Rapid species radiations provide insight into the process of speciation and diversification. The radiation of Chrysoperla carnea-group lacewings seems to be driven, at least in part, by their species–specific pre-mating vibrational duets. We associated genetic markers from across the genome with courtship song period in the offspring of a laboratory cross between Chrysoperla plorabunda and Chrysoperla adamsi, two species primarily differentiated by their mating songs. Two genomic regions were strongly associated with the song period phenotype. Large regions of chromosomes one and two were associated with song phenotype, as fewer recombination events occurred on these chromosomes relative to the other autosomes. Candidate genes were identified by functional annotation of proteins from the C. carnea reference genome. The majority of genes that are associated with vibrational courtship signals in other insects were found within QTL for lacewing song phenotype. Together these findings suggest that decreased recombination may be acting to keep together loci important to reproductive isolation between these species. Using wild-caught individuals from both species, we identified signals of genomic divergence across the genome. We identified several candidate genes both in song-associated regions and near divergence outliers including nonA, fruitless, paralytic, period, and doublesex. Together these findings bring us one step closer to identifying the genomic basis of a mating song trait critical to the maintenance of species boundaries in green lacewings.

description: We study the Langevin dynamics of the adaptive immune system, modelled by a lymphocyte network in which the B cells are interacting with the T cells and antigen. We assume that B clones and T clones are evolving in different thermal noise environments and on different timescales. We derive stationary distributions and use statistical mechanics to study clonal expansion of B clones in this model when the B and T clone sizes are assumed to be the slow and fast variables respectively and vice versa. We derive distributions of B clone sizes and use general properties of ferromagnetic systems to predict characteristics of these distributions, such as the average B cell concentration, in some regimes where T cells can be modelled as binary variables. This analysis is independent of network topologies and its results are qualitatively consistent with experimental observations. In order to obtain full distributions we assume that the network topologies are random and locally equivalent to trees. The latter allows us to employ the Bethe-Peierls approach and to develop a theoretical framework which can be used to predict the distributions of B clone sizes. As an example we use this theory to compute distributions for the models of immune system defined on random regular networks.

description: The time-dependent Mandel Q parameter, Q(T), provides a measure of photon number variance for a light source as a function of integration time. Here, we use Q(T) to characterise single photon emission from a quantum emitter in hexagonal boron nitride (hBN). Under pulsed excitation a negative Q parameter was measured, indicating photon antibunching at an integration time of 100 ns. For larger integration times Q is positive and the photon statistics become super-Poissonian, and we show by comparison with a Monte Carlo simulation for a three-level emitter that this is consistent with the effect of a metastable shelving state. Looking towards technological applications for hBN single photon sources, we propose that Q(T) provides valuable information on the intensity stability of single photon emission. This is useful in addition to the commonly used $g^{(2)}(τ)$ function for the complete characterisation of a hBN emitter.

description: We study theoretically by means of quantum electrodynamics the vortex radiation of a relativistic electron in a uniform magnetic field. The exact expressions for the probability of emission of a photon with a certain angular momentum are found. The classical asymptotics $\hbar\to 0$ of this probability does not match the angular momentum flux density calculated by the classical method using the symmetrized energy-momentum tensor. Although the flux of angular momentum integrated over the radiation directions is the same in both cases. We found the angular momentum flux of the radiation field using the canonical (not symmetrized) energy-momentum tensor and showed that the flux obtained in this way coincide with the classical limit for the probability of photon emission.

description: Background: New erythrocyte parameters are reported by the Sysmex XE 5000 analyzer. This instrument measures the hemoglobin (Hb) content of individual red cells, calculates the percentage of hypochromic red cells (%Hypo He) and the percentage of hyperchromic red cells (%Hyper He) and quantifies the proportion of marginally sized erythrocytes (%Micro R and %Macro R). The goals of the study were to establish the reference range for erythrocyte extended parameters, their value in different types of anemia and to investigate their reliability in the study of disorders of iron metabolism. Materials: Three hundred and ninety samples were analyzed. The Kolmogorov-Smirnoff test, independent samples t-test and Pearson correlation were calculated; receiver operating characteristic (ROC) curve analysis was used to determine their diagnostic performance. Results: The values of the four parameters studied were normally distributed and statistically different (p<0.0001) in the different groups of patients; the only exception was %Hypo He in cases of iron deficiency and thalassemia (p=0.3758). Results of ROC curve analysis for %Hypo He in the diagnosis of restricted erythropoiesis reticulocyte Hb content (reticulocyte hemoglobin content, Ret He <29 pg) were: area under the curve 0.963; cut-off 1.8%; sensitivity 98.3%; specificity 91.1%. Conclusions: The new parameters appear to be sensitive for detecting small changes in the number of red cells with inadequate hemoglobinization and volume. Clin Chem Lab Med 2009;47:1411–6.

description: Lattice networks with dissipative interactions can be used to describe the mechanics of discrete meso-structures of materials such as 3D-printed structures and foams. This contribution deals with the crack initiation and propagation in such materials and focuses on an adaptive multiscale approach that captures the spatially evolving fracture. Lattice networks naturally incorporate non-locality, large deformations, and dissipative mechanisms taking place inside fracture zones. Because the physically relevant length scales are significantly larger than those of individual interactions, discrete models are computationally expensive. The Quasicontinuum (QC) method is a multiscale approach specifically constructed for discrete models. This method reduces the computational cost by fully resolving the underlying lattice only in regions of interest, while coarsening elsewhere. In this contribution, the (variational) QC is applied to damageable lattices for engineering-scale predictions. To deal with the spatially evolving fracture zone, an adaptive scheme is proposed. Implications induced by the adaptive procedure are discussed from the energy-consistency point of view, and theoretical considerations are demonstrated on two examples. The first one serves as a proof of concept, illustrates the consistency of the adaptive schemes, and presents errors in energies. The second one demonstrates the performance of the adaptive QC scheme for a more complex problem.

description: Pitohui cristatus arthuri Hartert Pitohui cristatus arthuri Hartert, 1930b: 61 (Cyclops Mountains). Now Pitohui cristatus arthuri Hartert, 1930. See Dickinson, 2003: 490, Boles, 2007: 435, and Dumbacher et al, 2008. HOLOTYPE: AMNH 294125, adult male, collected at Camp I, Cyclops Mountains, 02.32S, 140.36E (USBGN, 1982), Papua Province, Indonesia, on 23 August 1928, by Ernst Mayr (no. 1962). COMMENTS: Hartert cited Mayr’s unique field number of the holotype in the original description and listed two specimens, a male and a female. The paratype is AMNH 656543, female, collected at Camp I, Cyclops Mountains, on 22 August 1928, by Ernst Mayr (no. 1948). Mayr (1930) described his itinerary and collecting localities. His expedition was supported jointly by Walter Rothschild and by Leonard C. Sanford for AMNH (Hartert, 1930a: 18–19). The holotype came to AMNH with Sanford’s portion of the collection, and the paratype came in 1932, when AMNH purchased the Rothschild Collection.

description: To exploit a given physical system for quantum information processing, it is critical to understand the different types of noise affecting quantum control. Distinguishing coherent and incoherent errors is extremely useful as they can be reduced in different ways. Coherent errors are generally easier to reduce at the hardware level, e.g. by improving calibration, whereas some sources of incoherent errors, e.g. T2* processes, can be reduced by engineering robust pulses. In this work, we illustrate how purity benchmarking and randomized benchmarking can be used together to distinguish between coherent and incoherent errors and to quantify the reduction in both of them due to using optimal control pulses and accounting for the transfer function in an electron spin resonance system. We also prove that purity benchmarking provides bounds on the optimal fidelity and diamond norm that can be achieved by correcting the coherent errors through improving calibration.

description: The number of molecules involved in a cell or subcellular structure is sometimes rather small. In this situation, ordinary macroscopic-level fluctuations can be overwhelmed by non-negligible large fluctuations, which results in drastic changes in chemical-reaction dynamics and statistics compared to those observed under a macroscopic system (i.e., with a large number of molecules). In order to understand how salient changes emerge from fluctuations in molecular number, we here quantitatively define small-number effect by focusing on a `mesoscopic' level, in which the concentration distribution is distinguishable both from micro- and macroscopic ones, and propose a criterion for determining whether or not such an effect can emerge in a given chemical reaction network. Using the proposed criterion, we systematically derive a list of motifs of chemical reaction networks that can show small-number effects, which includes motifs showing emergence of the power law and the bimodal distribution observable in a mesoscopic regime with respect to molecule number. The list of motifs provided herein is helpful in the search for candidates of biochemical reactions with a small-number effect for possible biological functions, as well as for designing a reaction system whose behavior can change drastically depending on molecule number, rather than concentration.

description: Trapped inflation is a mechanism in which particle production from the moving inflaton is the main source of friction in the inflaton equation of motion. The produced fields source inflaton perturbations, which dominate over the vacuum ones. We employ the set of equations for the inflaton zero mode and its perturbations which was developed in the original work on trapped inflation, and which we extend to second order in the perturbations. We build on this study by updating the experimental constraints, and by replacing the existing approximate solutions with more accurate ones. We obtain a different numerical value for the amplitude of the scalar power spectrum, and a parametrically different result for the bispectrum. This has implications for the allowed region of parameter space in models of trapped inflation, and for some of the phenomenological results obtained in this region. The main results in the allowed region are the following: monomial inflaton potentials, such as $V \propto φ,\, φ^2$ can be compatible with the data, and (in a portion of the allowed region) the inflaton can be sub-Planckian over all the "observable" stage of inflation; gravitational waves from this mechanism are too small to be observed in the foreseeable future; a non-gaussianity parameter $-60 < f_{\rm NL} < -20 $ is obtained in the allowed region for exactly equilateral configurations, with a mild dependence on the parameters of the model and of the inflaton potential.
