description: In Twitter, and other microblogging services, the generation of new content by the crowd is often biased towards immediacy: what is happening now. Prompted by the propagation of commentary and information through multiple mediums, users on the Web interact with and produce new posts about newsworthy topics and give rise to trending topics. This paper proposes to leverage on the behavioral dynamics of users to estimate the most relevant time periods for a topic. Our hypothesis stems from the fact that when a real-world event occurs it usually has peak times on the Web: a higher volume of tweets, new visits and edits to related Wikipedia articles, and news published about the event. In this paper, we propose a novel time-aware ranking model that leverages on multiple sources of crowd signals. Our approach builds on two major novelties. First, a unifying approach that given query q, mines and represents temporal evidence from multiple sources of crowd signals. This allows us to predict the temporal relevance of documents for query q. Second, a principled retrieval model that integrates temporal signals in a learning to rank framework, to rank results according to the predicted temporal relevance. Evaluation on the TREC 2013 and 2014 Microblog track datasets demonstrates that the proposed model achieves a relative improvement of 13.2% over lexical retrieval models and 6.2% over a learning to rank baseline.

description: This paper describes a junction property of nanoparticle(NP) embedded SiO2/Si. P+Si NPs and/or combination with Ag particles were tested. A liquid source SiO2 layer was obtained using Perhydropolysilazane (PHPS), which shows good
passivation property on Si. After spin coating deposition, NP embedded SiO2 layers were obtained using a hot steam
annealing at 600C. The p+SiNPs embedded SiO2/Si(n) hetero structure showed rectifying property. A forward bias
current under illumination was lower than the dark, indicating a memory effect, which can be explained by hole trap of
floating Si NPs in the SiO2 film. Using this property, selective contact was tested using the combination of p+ Si NP and
Ag particle. An Ag particle embedded SiO2 was an ohmic contact. On the other hand, the SiO2 film including both p+Si
NPs and Ag particle showed rectifying property with no memory effect. In addition forward bias current increased by
illumination.

description: The optical path length and the intensity of the incident light reaching the solar cell could be enhanced
by incorporating antireflective and light scattering nanostructures. In this work, the upright periodic nanopyramid
structures were fabricated on the surface of a glass substrate using UV nanoimprint lithography, which was employed
in this case as a protective layer for solar cells, in addition to its antireflection coating function. The haze value was
significantly increased for upright nanopyramid patterned glass, especially, in the wavelengt h range 300-600 nm,
which implies that strong light scattering by upright nanopyramid structure. By replacing a bare protective glass with
upright nanopyramid patterned glass, the power conversion efficiency of the monocrystalline Si and commercially
made polycrystalline Si solar cells were substantially enhanced about 10.89% and 8.22% due to the scattering and
prolong the optical path length by the upright nanopyramid structures. In addition, the surface of the patterned glass
exhibited hydrophobic propert ies due to the surface nanostructures and the self-assembled monolayer coating. The
high hydrophobicity provided the solar cell with a self-cleaning functionality.

description: We report on results from new high-sensitivity, high-resolution 86GHz (3.5 millimeter) observations of the jet base in the nearby radio galaxy M87, obtained by the Very Long Baseline Array in conjunction with the Green Bank Telescope. The resulting image has a dynamic range exceeding 1500 to 1, the highest ever achieved for this jet at this frequency, resolving and imaging a detailed jet formation/collimation structure down to ~10 Schwarzschild radii (Rs). The obtained 86GHz image clearly confirms some important jet features known at lower frequencies, i.e., a wide-opening angle jet base, a limb-brightened intensity profile, a parabola-shape collimation profile and a counter jet. The limb-brightened structure is already well developed at < 0.2mas (< 28Rs, projected) from the core, where the corresponding apparent opening angle becomes as wide as ~100 degrees. The subsequent jet collimation near the black hole evolves in a complicated manner; there is a "constricted" structure at tens Rs from the core, where the jet cross section is locally shrinking. We suggest that an external pressure support from the inner part of radiatively-inefficient accretion flow may be dynamically important in shaping/confining the footprint of the magnetized jet. We also present the first VLBI 86GHz polarimetric experiment for this source, where a highly polarized (~20%) feature is detected near the jet base, indicating the presence of a well-ordered magnetic field. As a by-product, we additionally report a 43/86 GHz polarimetric result for our calibrator 3C 273 suggesting an extreme rotation measure near the core.

The GM(1,1) Model Based on High Order AGO Generation
Creators: name: NI, Jiayu
Publisher: name: figshare

Subjects: Numerical analysis

description: In recent years, the application of grey system theory in various fields is more and more extensive. One of the models is grey prediction model, among which GM(1,1) is the most famous, simplest, and widely used model. However, due to the modeling mechanism, the simulation effect of GM(1,1) model on the oscillation sequence is not ideal. Moreover, oscillatory sequences usually fail the quasi-exponential law test. These problems limit the applicability of GM(1,1) model. Considering the advantage of GM(1,1) model in simulating monotone sequence, it can be applied to the AGO sequence of oscillatory sequence to establish the GM(1,1) model of AGO sequence, and then restore the modeling of AGO sequence to the original sequence through the restoration program.

description: In this work we investigated the influence of fabrication procedure of indium tin oxide (ITO) seed
layers, acting as front contacts in silicon heterojunction solar cells, on the growth of ZnO antireflective layers.
Furthermore, ZnO nanorod growth out of ZnCl2 and Zn(NO3)2 solution was compared. It was observed that for both
ZnCl2 and Zn(NO3)2 nanorod layers, the ITO sheet resistance affects the density and size of resulting nanorods. The
most effective antireflective nanorod layers grew on an ITO layer with a sheet resistance of approximately 50 Ω. In
this case, the nanorod layers had a suitable density, which was neither too low nor too high. The application of such a
nanorod antireflective layer in a SHJ solar cell led to a relative gain in the short circuit current density by 0.6 %.

description: The variable nature of solar energy required for its efficient use the complement of energy storage to
adapt adequately the generation and production curves. As PV/T technology produces both electricity and heat energy,
two storage devices should be necessary. Batteries are the most common method for storing electricity. Nevertheless,
different technologies are available to store heat energy. Thermal energy storage can be classified into sensible or latent
heat systems, depending if the substance that storages the energy changes its temperature during the process or its
physical phase. Phase Change Materials (PCM´s) involve high amount of energy with small changes in volume and
temperature so they are promising materials to keep temperature almost constant and store heat energy.
In this work a complete study of different types of PCM for its application in PV/T is presented. For this purpose,
different materials are classified in terms of its chemical structure and also by its use in PV/T technology. Great number
of substances susceptible to be used as PCMs in a heat storage system is showed in the work by an exhaustive
bibliography review. Only those PCM´s with melting temperature lower than 70 ºC have been taken in mind for this
work. Upper temperatures do not provide enough PV efficient increase

description: After reviewing the hole argument and its relations with initial value problem and general covariance, we shall discuss how much freedom one has to define the physical state of a system in a generally covariant (or gauge covariant) field theory. We shall show that in gauge covariant theories (and generally covariant theories with a a compact space) one has no freedom and one is forced to declare as physically equivalent two configurations which differ by a gauge transformation (or by a global spacetime diffeomorphism), as it is usually prescribed. On the contrary, when space is not compact, the result proven for the compact case does not hold true and one may have different options to define physically equivalent configurations, still preserving determinism.

description: AiSoVol project consists on the development, manufacturing and testing in a controlled environment of
a new concept of photovoltaic modules, conceived for facilitating their use as architectural elements. Thus, the
modules will be fabricated by encapsulating its constituent electrical elements (cells and interconnections) with
lamination techniques at low curing temperatures and using transparent thermoplastic instead of tempered glass, as
well as binding materials structurally strengthened by a grid made of high-tenacity yarns, such as the ones used in sail
technologies and thus avoiding the need for aluminum frames. This type of solution will provide, due to the nature of
the constituent materials, lighter PV modules which can adapt easier to different surfaces. In this paper the
methodology followed to define a suitable lamination process compatible to obtain reliable AiSoVol photovoltaic
modules is described. Results achieved from materials and processes validation will pave the way for manufacturing
the prototypes in next project phase.

integration, has been fabricated and characterised at 1000 Wm-2 (higher irradiance)and 500 Wm-2 (lower irradiance). This
paper investigates the use of a commercially available organic phase change material (PCM) RTÒ50 for limiting the
temperature rise in the system within indoor testing conditions. The results demonstrate an average of 7.4°C reduction in
the system temperature at 1000 Wm-2 and 4.8°C at 500 Wm-2. It also resulted in 17% increase in electrical power
efficiency at 1000 Wm-2 and 6.5 % at 500 Wm-2 within the PCM incorporated system as compared to a naturally
ventilated system. Further, differential scanning calorimetric technique has been applied to assess the thermophysical
properties of the PCM as any erroneous data may affect the prudent selection of PCM for particular applications. The
outcome of the DSC analysis performed on the PCM indicates 10.6 % underestimation in the reported melting peak
temperature value of the PCM.

description: In a hot carrier solar cell the collection of hot carriers requires electrical contacts with a narrow energy
pass bandwidth, known as energy selective contacts to minimise energy lost as heat via the increase in entropy at the
contacts. However due to the large effective mass of holes compared to electrons majority of the energy from
absorbed photons are taken up by electrons, 94.3% in the case for an InAs absorber. Therefore a carrier selective
contact can be used rather than an energy selective contact for the collection of holes in a hot carrier solar cell with
minimal energy loss from the hot hole population cooling. Copper iodide (CuI) has been identified as a material
which can potentially be used to collect holes. Preparation of CuI films is done by solution processes, dissolving CuI
powder in a solvent and spin coating on the substrate. The material properties such as optical properties, crystal
structure and film morphology are studied in the context of its suitability for use as an electron blocking and hole
collecting layer for the hot carrier solar cell.

description: Floquet theory provides rigorous foundations for the theory of periodically driven quantum systems. In the case of non-periodic driving, however, the situation is not so well understood. Here, we provide a critical review of the theoretical framework developed for quasi-periodically driven quantum systems. Although the theoretical footing is still under development, we argue that quasi-periodically driven quantum systems can be treated with generalizations of Floquet theory in suitable parameter regimes. Moreover, we provide a generalization of the Floquet-Magnus expansion and argue that quasi-periodic driving offers a promising route for quantum simulations.

description: Laser ablation of a Near-Earth Object (NEO) on a collision course with Earth produces a cloud of ejecta which exerts a thrust on the NEO, deflecting it from its original trajectory. Ablation may be performed from afar by illuminating an Earth-targeting asteroid or comet with a stand-off "DE- STAR" system consisting of a large phased-array laser in Earth orbit. Alternatively, a much smaller stand-on "DE-STARLITE" system may travel alongside the target, slowly deflecting it from nearby over a long period. This paper presents orbital simulations comparing the effectiveness of both systems across a range of laser and NEO parameters. Simulated parameters include magnitude, duration and, for the stand-on system, direction of the thrust, as well as the type, size and orbital characteristics of the target NEO. These simulations indicate that deflection distance is approximately proportional to the magnitude of thrust and to the square of the duration of ablation, and is inversely proportional to the mass. Furthermore, deflection distance shows strong dependence on thrust direction with the optimal direction of thrust varying with the duration of laser activity. As one example, consider a typical 325 m asteroid: beginning 15 yr in advance, just 2 N of thrust from a ~20 kW stand-on DE-STARLITE system is sufficient to deflect the asteroid by 2 R_e. Numerous scenarios are discussed as is a practical implementation of such a system consistent with current launch vehicle capabilities.

description: We elaborate on the idea that loop corrections to belief propagation could be dealt with in a systematic way on pairwise Markov random fields, by using the elements of a cycle basis to define region in a generalized belief propagation setting. The region graph is specified in such a way as to avoid dual loops as much as possible, by discarding redundant Lagrange multipliers, in order to facilitate the convergence, while avoiding instabilities associated to minimal factor graph construction. We end up with a two-level algorithm, where a belief propagation algorithm is run alternatively at the level of each cycle and at the inter-region level. The inverse problem of finding the couplings of a Markov random field from empirical covariances can be addressed region wise. It turns out that this can be done efficiently in particular in the Ising context, where fixed point equations can be derived along with a one-parameter log likelihood function to minimize. Numerical experiments confirm the effectiveness of these considerations both for the direct and inverse MRF inference.

Under non-negative Schur-concave functions, the vector-type uncertainty relation generates a family of infinitely many detectors to check genuine multipartite entanglement. We also introduce the concept of $k$-separable circles via geometric distance for probability vectors, which include at most $(k-1)$-separable states. The entanglement witness is also generalized to a universal entanglement witness which is able to detect the $k$-separable states more accurately.

description: Scanning tunneling spectroscopy measurements of superconducting thin lanthanum films grown on a normal metal tungsten substrate reveal an extraordinarily large broadening of the coherence peaks. The observed broadening corresponds to very short electron-like quasiparticle lifetimes in the tunneling process. A thorough analysis considering the different relaxation processes reveals that the dominant mechanism is an efficient quasiparticle relaxation at the interface between the superconducting film and the underlying substrate. This process is of general relevance to scanning tunneling spectroscopy studies on thin superconducting films and enables measurements of film thicknesses via a spectroscopic method.

description: Series-parallel interconnection of tandem cells is an alternate approach to standard monolithic
interconnection design. By matching string voltage instead of cell current, a broad range of top cell bandgaps can be
effectively combined to produce near-ideal efficiency. Annual energy yield using spectrum and weather data collected
by NREL was simulated for tandem module designs. The series-parallel approach is extremely tolerant of spectrum and
temperature variation, achieving a simulated yield of >99% of the ideal four-terminal tandem for a given bandgap.
Importantly, a wide range of bandgaps (1.4eV to 2.0 eV) also achieved energy yields greater than 95% of that achieved
for the ideal bandap (~1.65eV). The series-parallel approach provides broad design flexibility, particularly for the top
cell, to enable relatively free choice of the best material for efficiency and manufacturability rather than being constrained
solely by current matching.

description: Different approaches like round wire interconnectors, shingled or back-contact cells have been
presented in the past to improve the cell-to-module efficiency ratio by reducing the shading losses of interconnector
ribbons.
We present a new cell interconnector design based on a triangular cross section to further improve modules based on
interconnector ribbons. We analyze the optical behavior of the concept and compare it with rectangular ribbons and
round wire interconnectors. An evaluation of the new concept using optical ray tracing is performed. Results show an
advantage in optical performance of 2.35% of the new concept compared to standard interconnector ribbons under
perpendicular irradiation as well as 1.94% compared to round wires. An analysis using irradiation data (DNI) shows a
superior optical performance of the TriCon-Concept. We find that in an elevation tracked module using TriCon
2.32% more light reaches the cell surface over the year compared to rectangular interconnectors (5BB) and 2.02%
compared to round wires.

description: The orientation of Christian churches is a well-known distinctive feature of their architecture. There is a general tendency to align their apses in the solar range, favoring orientations close to the east (astronomical equinox), although the alignments in the opposite direction, namely, with the apse towards the west, are not unusual. The case of the churches built in northwest Africa before the arrival of Islam is paradigmatic in this regard, and may reflect earlier traditions. The Canary Islands is the western end of this North African cultural koine, so we thought it would be relevant to study a compact set of old churches in one of the islands of the archipelago, choosing to start our project with Lanzarote. We have measured the orientation of a total of 30 churches built prior to 1810, as well as a few buildings of later times, nearly a complete sample of all the island Christian sanctuaries. The analysis of this sample indicates that a definite orientation pattern was followed on the island but, unlike the standard one often found in most of the Christian world, this prototype is twofold. On the one hand, the representative orientation to the east (or west) is present. However, the sample has also a marked orientation towards the north-northeast, which is as far as we know a pattern exclusive of Lanzarote. We analyze the reasons for this rule and suggest that one possible explanation could be a rather prosaic one, namely, that sometimes earthly needs are more relevant than religious beliefs.

Awarded 810 hours of observing time, the full statistical sample (at 1.5 GHz) plus several studies of individual objects have now been published. Combined with multi-wavelength follow up observations, this survey will provide a unique legacy data set of our Galactic back yard. We present an overview of the LeMMINGs results so far, including the 1.5 GHz sample results and associated Chandra X-ray data. We describe the next steps for LeMMINGs to analyse the 5 GHz survey and produce widefield images to categories all radio sources in the LeMMINGs galaxies.

description: Geometric approaches to network analysis combine simply defined models with great descriptive power. In this work we provide a method for embedding directed acyclic graphs into Minkowski spacetime using Multidimensional scaling (MDS). First we generalise the classical MDS algorithm, defined only for metrics with a Euclidean signature, to manifolds of any metric signature. We then use this general method to develop an algorithm to be used on networks which have causal structure allowing them to be embedded in Lorentzian manifolds. The method is demonstrated by calculating embeddings for both causal sets and citation networks in Minkowski spacetime. We finally suggest a number of applications in citation analysis such as paper recommendation, identifying missing citations and fitting citation models to data using this geometric approach.

description: Various peak effects in 2H-NbSe2 single crystals induced by particle irradiations were studied. 3 MeV proton irradiation magnified the peak effect induced by order-disorder transition of vortices, where the peak field shifts from high fields to low fields with increasing irradiation dose. For the peak effect in NbSe2 with splayed columnar defects (CDs), as the splayed angle increases, peak field gradually shifts from high fields to low fields. Numerical calculations have been conducted to investigate the mechanism of the peak effect. The calculated results exhibit excellent agreement with experimental observations. Analyses of field dependence of Jc reveal the formation of non-uniform Jc flow with increasing splayed angle, which plays a crucial role in inducing the self-field peak effect in superconductors with splayed CDs. In samples with symmetric splayed CDs with respect to the c-axis generated by 800 MeV Xe and 320 MeV Au ions, coexistence of order-disorder transition-induced peak effect and self-field peak effect was observed. In the case of 320 MeV Au irradiated samples, when the splay angle is small, the two peak effects transform into a broad peak, which has similarity to the anomalous peak effect observed in iron-based superconductors. Interestingly, the broad anomalous peak effect is strongly suppressed when the external magnetic field is applied parallel to one of splayed CDs.

description: We report the 273W anti-glaring module with curved-frame structure and 0.85mm thickness glass. The optical
simulation shows the reflectivity of curved module received by inspector is reduced 96.79% than flat panel by using
Tracepro software. And the outdoor anti-glaring performance of this anti-glaring module has reached larger than 60%
improvement than flat panel. However, the outdoor energy yield of anti-glaring module is lower (-0.19%) than flat
panel. But the anti-glaring module still has a lot of benefits, like more efficient land usage, drainage and light weight
(10.5 kg) which can be moved and installed quickly.

description: The energy-spectrum of two point-like particles interacting in a 3-D isotropic Harmonic Oscillator (H.O.) trap is related to the free scattering phase-shifts $δ$ of the particles by a formula first published by Busch et al. It is here used to find an expression for the \it shift \rm of the energy levels, caused by the interaction, rather than the perturbed spectrum itself. In the limit of high energy (large quantum number $n$ of the H.O.) this shift is shown to be given by $-2\fracδπ$, also valid in the limit of infinite as well as zero scattering length at all H.O. energies. Numerical investigation shows that the shifts differ from the exact result of Busch et al, by less than $

description: To reduce cell-to-module (CtM) losses for aesthetically appreciated all-black modules we applied a
black powder coating with low infrared absorption to standard back foils used in PV modules. Upon the application
of such powder coating the IR reflective properties of the underlying substrate are largely preserved. For Cu foil
substrates approximately 85% reflection in near-infrared was recorded, while for a white polyamide substrate
reflection was 60%. These black, IR reflecting back foils were incorporated in single-cell laminates with n-Pasha
bifacial solar cells. From these structures the potential Isc gain from the application of such coatings in PV modules as
compared to conventional all-black modules is estimated to be 1.4 – 1.8%.

description: A mini-module on one silicon wafer has been fabricated through assembling a small size of SIS
(semiconductor-insulator-semiconductor) device taking on a bypass diode feature in a reverse saturation current,
with HIT (heterojunction with intrinsic thin film) solar cell. The architecture is that the solar cell is on the front
side while the inbuilt bypass diode is on the rear side. The data showed that the output character of the integrated
devices possessed obviously hermaphroditical behavior at forward and reverse biases, which was available to
protect the mini-system from deterioration upon shadowing. The integrated system as an independent output
power device can be further optimized against the temperature influence.

description: Conversion of energy of beta-particles into electric energy in a p-n junction based on direct-bandgap
semiconductors, such as GaAs, is analyzed considering realistic semiconductor system parameters. An expression for
the collection coefficient, Q, of the electron-hole pairs generated by beta-electrons is derived taking into account the
existence of the dead layer. We show that the collection coefficient of beta-electrons emitted by a 3H-source to a
GaAs p-n junction is close to 1 in a broad range of electron lifetimes in the junction, ranging from 10-9 to 10-7 s. For
the combination 147Pm/GaAs, Q is relatively large (≥ 0.4) only for quite long lifetimes (about 10-7 s) and large
thicknesses (about 100 μm) of GaAs p-n junctions. For realistic lifetimes of minority carriers and their diffusion
coefficients, the open-circuit voltage realized due to the irradiation of a GaAs p-n junction by beta-particles is
obtained. The attainable beta-conversion efficiency  in the case of a 3H/GaAs combination is found to exceed that of
the 147Pm /GaAs combination.

description: The increment of the PV market has led to multiple PV installations which operate under non-ideal conditions. Heavy shading
is expected in rooftop installations, Building Integrated Photovoltaics and solar powered vehicles. Demand of an increased energy-yield,
despite of the non-uniform conditions render reconfigurable topologies a promising solution for such installations. Evaluation of the
performance of a PV module can be performed either on the field or in a detailed simulation environment. The problem of the existing
solutions is a large cost investment for constructing all potential topologies and the large time requirements for detailed simulation of the
entire module. A simulation framework is proposed here which can significantly speed up the evaluation process of different reconfigurable
PV module instantiations and conventional modules for different operating scenarios with a high accuracy level.

description: STR has recently developed new non-EVA encapsulants for PV modules based on polyolefin
elastomers (POE’s). These materials have many advantages compared to traditional EVA based encapsulants like
improved thermal and chemical stability, minimized corrosive potential, lower moisture vapor transmission rate
(MVTR), improved electrical properties and PID resitance [1]. However, some similarities remain, like the need for a
curing approach where the encapsulant is transformed from a thermoplastic into an elastomer during lamination. In
this regard, lamination cycle optimization is required in order to obtain a good compromise between sufficient curing
and optimal performance and reliability of the correspondent PV module. Special focus will be place on measuring
the main properties that could be affected by poor cure levels like i) creep resistance, ii) adhesion to glass, iii)
adhesion retention after DH85/85 and iv) light transmission. Lamination cycle times similar to standard EVA
encapsulants are desirable.

description: An analysis of the minority carrier lifetime of individual non-dislocated grains before and after phosphorus diffusion
gettering suggests that smaller grains respond less to the gettering process than larger grains. The response is highest
in the top and bottom positions of the ingot, since these positions are heavily polluted by the ingot red-zone. However,
independently of position, there is a clear trend in the response decreasing approximately linearly with the smallest
dimension of the grains. This can be related to increased influence from recombination active grain boundaries, which
appear to affect the intragranular response up to 2mm from the boundary.
