Self-esteem, self-complexity, and reactions to naturally-occurring events
Creators: name: Chew, Barry
Publisher: name: University of British Columbia
Year: 2010

description: Prior research has established that individual differences in self-esteem moderate reactions to self-relevant events. Although all people generally favour positive outcomes to negative outcomes, low self-esteem (LSE) people exhibit more affective extremity in response to artificially-contrived events than high self-esteem (HSE) people. That is, LSE people exhibit more positive affective reactions to positive outcomes and more negative affective reactions to negative outcomes than HSE people. Two competing theoretical models have been proposed to account for the self-esteem differences in mood extremity in the laboratory setting—the defensive-styles hypothesis and the life-events composition hypothesis. Evidence from two studies, the Mood-Diary Study and the Role-Playing Study, provide support for the first hypothesis by demonstrating that (a) esteem-related differences in the cognitive interpretations and causal attributions for positive and negative self-relevant events exist for naturally-occurring events as well as laboratory-contrived feedback, (b) LSE subjects claimed that these events had a greater impact on their mood and that they considered them to be more personally important than did HSE subjects, and finally, (c) LSE subjects were more variable in their moods across time than their HSE counterparts. Although esteem-related differences in mood variability were predicted for both differences in the extremity and frequency of mood changes, the differences were obtained only on the frequency of change measure. Although the evidence for the defensive-styles model was substantial, there was also some evidence for the life-events composition model, which essentially postulates that the lives of HSE and LSE which essentially postulates that the lives of HSE and LSE individuals differed markedly. Finally, an exploratory investigation of the relationship between self-esteem, self-complexity, and mood indicated that the two individual difference variables were positively correlated and that both were related to the frequency of change in mood but not mood extremity.

description: Dynamical properties of complex networks are related to the spectral properties of the Laplacian matrix that describes the pattern of connectivity of the network. In particular we compute the synchronization time for different types of networks and different dynamics. We show that the main dependence of the synchronization time is on the smallest nonzero eigenvalue of the Laplacian matrix, in contrast to other proposals in terms of the spectrum of the adjacency matrix. Then, this topological property becomes the most relevant for the dynamics.

description: Thermal fluctuations in the coatings used to make high-reflectors are becoming significant noise sources in precision optical measurements and are particularly relevant to advanced gravitational wave detectors. There are two recognized sources of coating thermal noise, mechanical loss and thermal dissipation. Thermal dissipation causes thermal fluctuations in the coating which produce noise via the thermo-elastic and thermo-refractive mechanisms. We treat these mechanisms coherently, give a correction for finite coating thickness, and evaluate the implications for Advanced LIGO.

Silicon Solar Cell Improvements

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 552-556
description: Development of all-back-contact (ABC) silicon solar cells at the Australian National University (ANU), as part of a collaboration between Trina Solar and the Solar Energy Research Institute of Singapore (SERIS), is progressing, and 22.6% efficient ABC cells, based on the aperture-area of 13 cm2 that excludes busbars, were recently fabricated at ANU. When measured using the 16 cm2 aperture-area that includes busbars, the cells are 21.7% efficient. In this paper, we demonstrate the technique of removing shunts, associated in the development of ABC cells, by laser-assisted means. The laser that we use for the shunt removal is 532 nm diode pump solid state (DPSS) laser. The shunts are caused by residual boron (p+) diffusion within the phosphorus (n+) diffused region following the trench etch that separates the p and n regions. Photoluminescence (PL) imaging showed that apparent shunt regions were removed following this process. Analysis of ABC solar cells by dark IV characterisation further confirmed that the shunt resistance was increased by about 30-fold (350 to 11500 Ω.cm2). The effective removal of shunts has increased the cell efficiency by 0.5% absolute. Carrier recombination induced by laser damage appears to be minimal since open-circuit voltage of the ABC cells barely changes for pre- and post-laser ablation, although more detailed investigations are required.

The population of pulsars with interpulses and the implications for beam evolution

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The observed fraction of pulsars with interpulses, their period distribution and the observed pulse width versus pulse period correlation is shown to be inconsistent with a model in which the angle alpha between the magnetic axis and the rotation axis is random. This conclusion appears to be unavoidable, even when non-circular beams are considered. Allowing the magnetic axis to align from a random distribution at birth with a timescale of 70 Myrs years can, however, explain those observations well. The timescale derived is consistent with that obtained via independent methods. The probability that a pulsar beam intersects the line of sight is a function of the angle alpha and therefore beam evolution has important consequences for evolutionary models and for estimations of the total number of neutron stars. The validity of the standard formula for the spin-down rate, which is independent of alpha appears to be questionable.

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 3621-3625
description: Distributed generations of renewable energies, such as PV generation, are significant resources in a power system. To have higher power quality of power supply, multi-lever inverter is often employed for the power conversion. This paper presents a new self-balancing five-level inverter, which comprises two auxiliary circuits and a full-bridge inverter. The two conducting paths are used to alternately discharge the two input DC capacitors.
Therefore, the unbalanced DC voltage that often occurs in the conventional five-level inverter is avoided. Through the balancing control, the proposed inverter offers a near perfect output current to supply the load, and the size of the proposed system can be reduced due to smaller capacitances and inductances needed. A 400W, 200V input-voltage, 110VAC output-voltage prototype circuit is implemented to verify the performance of the proposed self-balancing five-level inverter.

description: This study looks into employees' communication, offering novel metrics which can help to predict a company's stock price. We studied the intranet forum of a large Italian company, exploring the interactions and the use of language of about 8,000 employees. We built a network linking words included in the general discourse. In this network, we focused on the position of the node representing the company brand. We found that a lower sentiment, a higher betweenness centrality of the company brand, a denser word co-occurrence network and more equally distributed centrality scores of employees (lower group betweenness centrality) are all significant predictors of higher stock prices. Our findings offers new metrics that can be helpful for scholars, company managers and professional investors and could be integrated into existing forecasting models to improve their accuracy. Lastly, we contribute to the research on word co-occurrence networks by extending their field of application.

description: Continuous variable entanglement is a manifestation of nonclassicality of quantum states. In this paper we attempt to analyze whether and under which conditions nonclassicality can be used as an entanglement criterion. We adopt the well-accepted definition of nonclassicality in the form of lack of well-defined positive Glauber Sudarshan P-function describing the state. After demonstrating that the classicality of subsystems is not sufficient for the nonclassicality of the overall state to be identifiable with entanglement, we focus on Gaussian states and find specific local unitary transformations required to arrive at this equivalency. This is followed by the analysis of quantitative relation between nonclassicality and entanglement.

description: We report our study of the evolution of superconductivity and the phase diagram of the ternary Fe(Se1-xTex)0.82 (0<=x<=1.0) system. We discovered a new superconducting phase with Tc,max = 14 K in the 0.3 < x < 1.0 range. This superconducting phase is suppressed when the sample composition approaches the end member FeTe0.82, which exhibits an incommensurate antiferromagnetic order. We discuss the relationship between the superconductivity and magnetism of this material system in terms of recent results from neutron scattering measurements. Our results and analyses suggest that superconductivity in this new class of Fe-based compounds is associated with magnetic fluctuations, and therefore may be unconventional in nature.

description: The observation of jet quenching in ultra-relativistic heavy ion collisions demonstrates significant energy loss of fast partons when passing through the created medium. Correlations between final-state particles at intermediate transverse momentum (1.0 $\lesssim$ $p_{T}$ $\lesssim$ 4.0 GeV/$c$) allow for study of the medium and its response to deposited energy. Comparison of these measurements in heavy ion collisions with measurements in proton collisions show strong modification of the correlation shape and particle yields. Two new structures are created, both extended in $Δη$, one centered at $Δϕ=0$ (``ridge'') and the other occurring at $Δϕ\approxπ\pm1.1$ (``shoulder''). In these proceedings, we describe the measurements of these structures that show consistency with a scenario of parton-medium interaction and response. We discuss a new analysis which selects on the angle of trigger particles relative to the reaction plane in Run7. New measurements of the centrality and $p_{T}$ dependencies of the structures raise the possibility that the same production mechanism may give rise to both phenomena.

description: Two different metrics are used to assess Forster resonance energy transfer (FRET) between fluorophores in the steady state: (1) acceptor-quenching of donor fluorescence, E (a.k.a. transfer efficiency); and (ii) donor-excited acceptor fluorescence, F-A-Dex. While E is still more widely used, F-A-Dex has been gaining in popularity for practical reasons among experimentalists who study biomembranes. Here, for the special case of membrane-bound fluorophores, we present a substantial body of experimental evidence that justifies the use of simple Stern-Volmer expressions when modeling either FRET metric under dilute-probe conditions. We have also discovered a dilute-regime correspondence between our Stern-Volmer expression for E and Wolber and Hudson's series approximation for steady-state Forster quenching in 2D. This novel correspondence allows us to interpret each of our 2D quenching constants in terms of both (i) an effective Forster distance, and (ii) two maximum acceptor-concentration limits, each of which defines its own useful experimental regime. Taken together, our results suggest a three-step strategy toward designing more effective steady-state FRET experiments for the study of biomembranes.

The latter approach has been extended by allowing for secondary charmonium production due to recombination of $c\bar{c}$ pairs in the medium, estimated from pp data at the same bombarding energy. Centrality and rapidity dependence of the nuclear modification factor for J/psi in d+Au, Cu+Cu and Au+Au collisions at RHIC are reproduced without fitting a single model parameter. A strong suppression of J/psi is predicted for LHC energies.

description: The accelerated Kepler problem is obtained by adding a constant acceleration to the classical two-body Kepler problem. This setting models the dynamics of a jet-sustaining accretion disk and its content of forming planets as the disk loses linear momentum through the asymmetric jet-counterjet system it powers. The dynamics of the accelerated Kepler problem is analyzed using physical as well as parabolic coordinates. The latter naturally separate the problem's Hamiltonian into two unidimensional Hamiltonians. In particular, we identify the origin of the secular resonance in the accelerated Kepler problem and determine analytically the radius of stability boundary of initially circular orbits that are of particular interest to the problem of radial migration in binary systems as well as to the truncation of accretion disks through stellar jet acceleration.

Silicon Solar Cell Improvements

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 1890-1893
description: One of the major challenges in production of crystalline silicon solar cells is to improve cell efficiency
with fast amortization of additional process tools and low cost of ownership. One mean to increase cell efficiency is
the incorporation of a one step laser doped selective emitter (LDSE). The selective emitter (SE) increases solar cell
efficiency due to enhanced blue response, and a reduced emitter saturation current density Joe. This work presents the
results from a joint industrial implementation of a Manz OneStep Selective Emitter tool at Yingli Solar and the
scientific investigations supporting this project. Results obtained on batches of 250 wafers showed efficiency gains of
up to 0.3%. In mass production an increase from 16.8% to 17.0% has been achieved so far (as of April 2012). The
cost benefit for SE is calculated at >2.2 mio US$ per year for a 70 MW line. The cell to module (CTM) loss was
investigated both in a standard module production line and in a laboratory with mini-modules and extensive
simulation and characterization techniques. In mass production the CTM loss for SE cells was at 1.6% exactly the
same than for REF cells. In the lab different combinations of EVA and glass were used. In average there was no
significant difference between REF and SE cells in CTM loss and the SE group in combination with the low UV
absorbing EVA even showed the lowest loss of all groups.

description: A new backsheet, based on cost effective polyolefins was developed for solar modules. Polyolefins are
known to withstand harsh environmental conditions. This polyolefin is especially modified for long term durability.
To perform a life time estimate, intensive and long-term weathering tests were performed. The polyolefin backsheet
was tested under harsh temperature and UV conditions in the xenon weatherometer and QUV-A. In parallel, heat
aging was done at temperatures of 110°C to 170°C. An Arrhenius extrapolation of the time to partial loss of property
was done to estimate a service life time. The calculated mean lifetime of the polyolefin based backsheet in a standard
solar module can be more than 50 years in Germany. The weathering is ongoing.

description: We present the novel embodiment of a photonic qubit that makes use of one continuous spatial degree of freedom of a single photon and relies on the the parity of the photon's transverse spatial distribution. Using optical spontaneous parametric downconversion to produce photon pairs, we demonstrate the controlled generation of entangled-photon states in this new space. Specifically, two Bell states, and a continuum of their superpositions, are generated by simple manipulation of a classical parameter, the optical-pump spatial parity, and not by manipulation of the entangled photons themselves. An interferometric device, isomorphic in action to a polarizing beam splitter, projects the spatial-parity states onto an even--odd basis. This new physical realization of photonic qubits could be used as a foundation for future experiments in quantum information processing.

Coupling convectively driven atmospheric circulation to surface rotation: Evidence for active methane weather in the observed spin rate drift of Titan

Subjects: subject: Astrophysics (astro-ph)

description: A large drift in the rotation rate of Titan observed by Cassini provided the first evidence of a subsurface ocean isolating the massive core from the icy crust. Seasonal exchange of angular momentum between the surface and atmosphere accounts for the magnitude of the effect, but observations lag the expected signal by a few years. We argue that this time lag is due to the presence of an active methane weather cycle in the atmosphere. An analytic model of the seasonal cycle of atmospheric angular momentum is developed and compared with time-dependent simulations of Titan's atmosphere with and without methane thermodynamics. The disappearance of clouds at the summer pole suggests the drift rate has already switched direction, signaling the change in season from solstice to equinox.

description: We determine the relationship between the turnaround radius, $R_{\rm t}$, and mass, $M_{\rm t}$, in $Λ$CDM, and in dark energy scenarios, using an extended spherical collapse model taking into account the effects of shear and vorticity. We find a more general formula than that usually described in literature, showing a dependence of $R_{\rm t}$ from shear, and vorticity. The $R_{\rm t}-M_{\rm t}$ relation differs from that obtained not taking into account shear, and rotation, especially at galactic scales, differing $\simeq 30\%$ from the result given in literature. This has effects on the constraint of the $w$ parameter of the equation of state. We compare the $R_{\rm t}-M_{\rm t}$ relationship obtained for the $Λ$CDM, and different dark energy models to that obtained in the $f(R)$ modified gravity (MG) scenario. The $R_{\rm t}-M_{\rm t}$ relationship in $Λ$CDM, and dark energy scenarios are tantamount to the prediction of the $f(R)$ theories. Then, the $R_{\rm t}-M_{\rm t}$ relationship is not a good probe to test gravity theories beyond Einstein's general relativity.

description: Scientific document understanding is challenging as the data is highly domain specific and diverse. However, datasets for tasks with scientific text require expensive manual annotation and tend to be small and limited to only one or a few fields. At the same time, scientific documents contain many potential training signals, such as citations, which can be used to build large labelled datasets. Given this, we present an in-depth study of cite-worthiness detection in English, where a sentence is labelled for whether or not it cites an external source. To accomplish this, we introduce CiteWorth, a large, contextualized, rigorously cleaned labelled dataset for cite-worthiness detection built from a massive corpus of extracted plain-text scientific documents. We show that CiteWorth is high-quality, challenging, and suitable for studying problems such as domain adaptation. Our best performing cite-worthiness detection model is a paragraph-level contextualized sentence labelling model based on Longformer, exhibiting a 5 F1 point improvement over SciBERT which considers only individual sentences. Finally, we demonstrate that language model fine-tuning with cite-worthiness as a secondary task leads to improved performance on downstream scientific document understanding tasks.

description: Electroluminescence (EL) imaging for photovoltaic
applications has been widely discussed in the last years. In
this contribution, the results of an all-around evaluation of
this technique in regard to defect detection and quality
assessment in photovoltaic modules are presented. The
optimal system parameters including the camera position,
its focal length and aperture size, the exposure time and
the applied voltage and current, are debated and defined.
The aptitude of the EL system for detecting failures and
deficiencies in both crystalline and thin film PV modules
(CdTe and CIGS) is thoroughly analyzed and an
exhaustive defect catalogue is established. In crystalline
silicon devices, cell breakages resulting from micro-cracks
were proven to represent the major problem and
remarkably affect the module performance. A linear
correlation between the size of the breakages and the
power drop in the module could be established. Further,
mechanical stress and temperature change could be
identified as the major cause behind the proliferation of
cracks and breakages. In thin film modules, EL imaging
proved a remarkable reduction in the size of localized
shunts under the effect of light soaking (together with a
performance improvement of up to 8%). Aside from that,
the system was applied for monitoring TCO corrosion
effects, laser scribing induced failures, as well as several
problems related to the module junction box in regard to
its sealing and the quality of its electric connectors.

description: In 2011, we completely changed the molecular design for newly anti-reflection (AR) coating materials, using different
molecular components to attain environmentally tough properties, compared with competitive AR materials developed by other
companies.
UV-setting and low temperature heat-setting AR coating materials having newly hybrid compositions are being developed. The flat
layer coating on glass substrates of PV modules and cells shows the enhancement of the light-trapping performace (LTP) to improve
~3% of the power generation efficiency. The flat AR layer can be manufactured by known coating processes with a total cost less than
1€/m2. In addition, we are originally developing a cheap coating process, namely dash-coating.
We believe that the big weak points of competitive AR materials are anti-fouling property and water-repellency, and NaHCO3
formation in the AR layer to damage the initial LTP. The present AR layer contains hydrophilic and hydrophobic sites perfectly
randomly, and the rain drops even including dirts can be repelled very easily.
The other specs for the texture necessary to the AR layer are satisfied. Manipulating the emboss structure to lower reflection and to
enhance the LTP ~5%, is underway.

description: The widespread of Coronavirus has led to a worldwide pandemic with a high mortality rate. Currently, the knowledge accumulated from different studies about this virus is very limited. Leveraging a wide-range of biological knowledge, such as gene ontology and protein-protein interaction (PPI) networks from other closely related species presents a vital approach to infer the molecular impact of a new species. In this paper, we propose the transferred multi-relational embedding model Bio-JOIE to capture the knowledge of gene ontology and PPI networks, which demonstrates superb capability in modeling the SARS-CoV-2-human protein interactions. Bio-JOIE jointly trains two model components. The knowledge model encodes the relational facts from the protein and GO domains into separated embedding spaces, using a hierarchy-aware encoding technique employed for the GO terms. On top of that, the transfer model learns a non-linear transformation to transfer the knowledge of PPIs and gene ontology annotations across their embedding spaces. By leveraging only structured knowledge, Bio-JOIE significantly outperforms existing state-of-the-art methods in PPI type prediction on multiple species. Furthermore, we also demonstrate the potential of leveraging the learned representations on clustering proteins with enzymatic function into enzyme commission families. Finally, we show that Bio-JOIE can accurately identify PPIs between the SARS-CoV-2 proteins and human proteins, providing valuable insights for advancing research on this new disease.

description: Azteca chartifex spiriti is a dominant arboreal ant living in forests and agroforests in southeast Bahia, Brazil. This species is especially important as it is considered as one of the main agents of natural biological control in cocoa plantations. This ant builds carton structures following a polydomous nesting strategy. Our study aimed to characterize the spatial structure of its nests and population organization living in. Seven colonies of A. chartifex spiriti were studied. In each one, the main nest, as well as six satellite constructions of different sizes, were measured and their population studied. We randomly sampled 350 workers per colony, 50 from the main nest and 50 from each one of the six selected structures. The sizes of these constructions were negatively related to their distance from the main nest. This central nest is where the reproductive gyne is supposed to be and where brood is present, while in the more peripheral and smallest satellites (~2 cm), workers are tending their mutualistic scale insects (Hemiptera: Coccidae). Practically only workers are found in nests of intermediate size. Workers of A. chartifex spiriti are weakly polymorph and their distribution by size category is not random within the colony territory. Workers are much more variable in the central nest compared to the peripheral structures, particularly in the smallest satellite constructions where minor workers are dominant. These characteristics are interpreted as a form of optimization of resource use by the ants.
Structure of interacting aggregates of silica nanoparticles in a polymer matrix: Small-angle scattering and Reverse Monte-Carlo simulations

description: Reinforcement of elastomers by colloidal nanoparticles is an important application where microstructure needs to be understood - and if possible controlled - if one wishes to tune macroscopic mechanical properties. Here the three-dimensional structure of big aggregates of nanometric silica particles embedded in a soft polymeric matrix is determined by Small Angle Neutron Scattering. Experimentally, the crowded environment leading to strong reinforcement induces a strong interaction between aggregates, which generates a prominent interaction peak in the scattering. We propose to analyze the total signal by means of a decomposition in a classical colloidal structure factor describing aggregate interaction and an aggregate form factor determined by a Reverse Monte Carlo technique. The result gives new insights in the shape of aggregates and their complex interaction in elastomers. For comparison, fractal models for aggregate scattering are also discussed.

description: Paper is devoted to the sol-gel containing dopands preparation technology. Sol-gel doping can be promising alternative to gas doping source for Si wafer based solar cells p-n junction formation. Sol–gel process is also an attractive alternative to other methods for synthesis of thin films for silicon solar cells because of low
temperature synthesis, simple equipment to be used, thin film formability and so on. In this study sol-gel silica was synthesized using tetraethoxysilane (TEOS) as a precursor and phosphoric acid as a source of phosphate ions. Thin layer of this material is spread by spin-coating process on a surface of silicon wafer and dried to form the phosphosilicate glass (SiO2 : (P2O5)n. Coated wafer is placed into diffusion furnace and held at high temperature under nitrogen ambient for p-n junction formation. Obtained sol-gel composition were analysed by FTIR to estimate dopant concentrations. Further p-n junctions from various sol-gel were produced, sheet resistance Rs and phosporous concentrations profiles were measured for comparative analysis.
Magnetic properties and pseudogap formation in infinite-layer nickelates: insights from the single-band Hubbard model

description: We study the magnetic and spectral properties of a single-band Hubbard model for the infinite-layer nickelate compound LaNiO$_2$. As spatial correlations turn out to be the key ingredient for understanding its physics, we use two complementary extensions of the dynamical mean-field theory to take them into account: the cellular dynamical mean-field theory and the dynamical vertex approximation. Additionally to the systematic analysis of the doping dependence of the non-Curie-Weiss behavior of the uniform magnetic susceptibility, we provide insight into its relation to the formation of a pseudogap regime by the calculation of the one-particle spectral function and the magnetic correlation length. The latter is of the order of a few lattice spacings when the pseudogap opens, indicating a strong-coupling pseudogap formation in analogy to cuprates.

description: Solar disinfection using photocatalyst and natural UV radiation is one of the most appropriate point-ofuse
water treatment methods in remote regions with restricted or unavailable access to electrical power and/or
chemical supplies. But the use of only a small fraction of the solar spectrum (5%) limits the system efficiency and
increases the cost. Photovoltaic solar cells can be integrated into hybrid photovoltaic-photocatalytic systems in a
single unit that uses the solar spectrum more efficiently, combining both photocatalysis for water purification using
UV light; and photovoltaics for electricity generation using visible and near infra-red light components. This
innovative approach could lead to low-cost clean water sensors suitable for all solar disinfection technologies, and to
high efficient, autonomous hybrid systems that could be used in rural areas with no access to electricity and/or in
emergency situations. This article presents the results from a second generation of this flat hybrid system, showing
the feasibility of the system as an autonomous system capable of deliver clean water.
