description: In this paper, three approaches to calculate the self-similarity exponent of a time series are compared in order to determine which one performs best to identify the transition from random efficient market behavior (EM) to herding behavior (HB) and hence, to find out the beginning of a market bubble. In particular, classical Detrended Fluctuation Analysis (DFA), Generalized Hurst Exponent (GHE) and GM2 (one of Geometric Method-based algorithms) were applied for self-similarity exponent calculation purposes. Traditionally, researchers have been focused on identifying the beginning of a crash. Instead of this, we are pretty interested in identifying the beginning of the transition process from EM to a market bubble onset, what we consider could be more interesting. The relevance of self-similarity index in such a context lies on the fact that it becomes a suitable indicator which allows to identify the raising of HB in financial markets. Overall, we could state that the greater the self-similarity exponent in financial series, the more likely the transition process to HB could start. This fact is illustrated through actual S\&P500 stocks.

description: The interdigitated back contact (IBC) solar cells developed at ANU have resulted in an independently
confirmed designated-area efficiency of 24.4 ± 0.7%, featuring short-circuit current density of 41.95 mA/cm2, opencircuit
voltage of 703 mV and 82.7% fill-factor. The cell, 2 x 2 cm2 in area, was fabricated on a 230 μm thick 1.5
Ω.cm n-type Cz wafer, utilising PECVD SiNx front surface passivation without front surface diffusion, rear side
thermal oxide / LPCVD Si3N4 passivation stack and evaporated aluminium contacts with a finger-to-finger pitch of
500 μm. This paper describes the design and fabrication of lab-scale high-efficiency IBC cells. Characterisation of
optical and electronic properties of the best produced cell is made, with subsequent incorporation into 3D device
modelling used to accurately quantify all losses. Loss analysis demonstrates that bulk and emitter recombination, bulk
resistive and optical losses are dominant, and suggests a clear route to efficiencies in excess of 25%. Additionally,
laser processing is explored as a means to simplify the manufacture of IBC cells, with a confirmed efficiency of
23.5% recorded for cells fabricated using damage-free deep UV laser ablation for contact formation. Meanwhile alllaser
doped cells, where every doping and patterning step is performed by lasers, are demonstrated with a preliminary
result of 19.1% conversion efficiency recorded.

description: We study the first gravitational wave, GW150914, detected by advanced LIGO and constructed from the data of measurement of strain relative deformation of the fabric of spacetime. We show that the time series from the gravitational wave obeys Tsallis's $q$-Gaussian distribution as a probability density and its dynamics evolve of the three associated Tsallis' indices named $q$-triplet. This fact strongly suggests that these black hole merger systems behave in a non-extensive manner. Furthermore, our results point out that the entropic indexes obtained as a function of frequency are useful statistical parameters to determine the dominant frequency when black hole coalescence is achieved.

description: The "main sequence of galaxies" $-$ defined in terms of the total star formation rate $ψ$ vs. the total stellar mass $M_*$ $-$ is a well-studied tight relation that has been observed at several wavelengths and at different redshifts. All earlier studies have derived this relation from integrated properties of galaxies. We recover the same relation from an analysis of spatially-resolved properties, with integral field spectroscopic (IFS) observations of 306 galaxies from the CALIFA survey. We consider the SFR surface density in units of log(M$_{\odot}$ yr$^{-1}$ Kpc$^{-2}$) and the stellar mass surface density in units of log(M$_{\odot}$ Kpc$^{-2}$) in individual spaxels which probe spatial scales of 0.5-1.5 Kpc. This local relation exhibits a high degree of correlation with small scatter ($σ= 0.23$ dex), irrespective of the dominant ionisation source of the host galaxy or its integrated stellar mass. We highlight: $(i)$ the integrated star formation main sequence formed by galaxies whose dominant ionisation process is related to star formation, for which we find a slope of 0.81 $\pm 0.02$; (ii) the spatially-resolved relation obtained with the spaxel analysis, we find a slope of 0.72 $\pm 0.04$; (iii) for the integrated main sequence we identified also a sequence formed by galaxies that are dominated by an old stellar population, which we have called the retired galaxies sequence.

description: Back-contact back-junction (BC-BJ) solar cells have been developed to meet the following objectives:
process simplification by POCl3 based co-diffusion steps and efficiency improvement independent of the co-diffusion
setup. In general, the process sequence is industrially feasible, requires not more than one temperature step
(co-diffusion), and implements only industrially available patterning technologies. The process simplification is
obtained by introducing a sophisticated co-diffusion process which combines solid diffusion sources with POCl3.
Compared with BC-BJ cells featuring solid diffusion sources at the front side, the number of process steps could be
decreased. Solar cells based on this process simplification feature conversion efficiencies up to 20.5 %. The
efficiency improvement is obtained by integrating an improved B-source, by adjusting the material properties and by
changing the pattern of the contact openings. BC-BJ cells based on the latter cell improvements feature conversion
efficiencies up to 21.6 %. The efficiency improvement is transferable to cells based on the regarded process
simplification featuring POCl3 as gaseous diffusion source.

description: The back junction back contact cell, and more specifically the interdigitated back contact (IBC) cell is
among the most appropriate cell design to achieve high cell efficiency. An important aspect to improve
manufacturability (e.g. reduce cost) of the cell and module is allowing larger feature sizes for the different regions at
the rear, for example the BSF. We propose a novel design of an IBC cell that enhances the effective lateral transport
of minority carriers (holes) and therefore allowing wide BSF regions. The novel design features an appropriate
conductive and well passivated p++-doped layer, referred to as a front floating emitter (FFE), on the front surface of
the IBC cell. This conductive FFE enables equally-sized interdigitated doping patterns of positive and negative
polarities on the rear, with similar cell pitch and efficiency compared to traditional IBC cells. It also enables larger
interconnection pads for easier module interconnection with marginal performance loss. Additional advantages are
expected such as relaxed alignment tolerances for patterning as well as interconnection processes. We report on the
proof-of-principle of this new cell concept, which we name “Mercury”, brought forward by 2D simulations and
experimental results on small and 6 inch cells. So far, based on an industrial process flow with stable results, these
cells yield full area efficiencies up to 19.6% on 6 inch and short-circuit densities well above 41 mA/cm2 for masked
smaller cells. Additionally, the Mercury cells show comparable efficiency loss at low illumination intensity as to
standard p-type H-pattern cell. Furthermore, we present the interconnection and cell design of our 6 inch Mercury cell
and prove that our first 4-cell Mercury modules pass the thermal cycling and damp heat test equivalent to the IEC
protocol demands.

description: The Innovative Strategies for Observations in the Arctic Atmospheric Boundary Layer Program (ISOBAR) is a research project investigating stable atmospheric boundary layer (SBL) processes, whose representation still poses significant challenges in state-of-the-art numerical weather prediction (NWP) models. In ISOBAR ground-based flux and profile observations are combined with boundary layer remote sensing methods and the extensive usage of different unmanned aircraft systems (UAS). During February 2017 and 2018 we carried out two major field campaigns over the sea ice of the northern Baltic Sea, close to the Finnish island of Hailuoto at 65°N. In total 14 intensive observational periods (IOPs) resulted in extensive SBL datasets with unprecedented spatiotemporal resolution, which will form the basis for various numerical modeling experiments. First results from the campaigns indicate numerous very stable boundary layer (VSBL) cases, characterized by strong stratification, weak winds, and clear skies, and give detailed insight in the temporal evolution and vertical structure of the entire SBL. The SBL is subject to rapid changes in its vertical structure, responding to a variety of different processes. In particular, we study cases involving a shear instability associated with a low-level jet, a rapid strong cooling event observed a few meters above ground, and a strong wave-breaking event that triggers intensive near-surface turbulence. Furthermore, we use observations from one IOP to validate three different atmospheric models. The unique finescale observations resulting from the ISOBAR observational approach will aid future research activities, focusing on a better understanding of the SBL and its implementation in numerical models.

description: We investigate cosmological structure formation in Fuzzy Dark Matter (FDM) with an attractive self-interaction (SI) with numerical simulations. Such a SI would arise if the FDM boson were an ultra-light axion, which has a strong CP symmetry-breaking scale (decay constant). Although weak, the attractive SI may be strong enough to counteract the quantum 'pressure' and alter structure formation. We find in our simulations that the SI can enhance small-scale structure formation, and soliton cores above a critical mass undergo a phase transition, transforming from dilute to dense solitons.

description: We constrain the coupling between axionlike particles (ALPs) and photons, measured with the superconducting resonant detection circuit of a cryogenic Penning trap. By searching the noise spectrum of our fixed-frequency resonant circuit for peaks caused by dark matter ALPs converting into photons in the strong magnetic field of the Penning-trap magnet, we are able to constrain the coupling of ALPs with masses around 2.7906-2.7914 neV/c2 to gaγ<1×10-11 GeV-1. This is more than one order of magnitude lower than the best laboratory haloscope and approximately 5 times lower than the CERN axion solar telescope (CAST), setting limits in a mass and coupling range which is not constrained by astrophysical observations. Our approach can be extended to many other Penning-trap experiments and has the potential to provide broad limits in the low ALP mass range.

description: In this paper we consider a layered heterostructure of an Abelian topologically ordered state (TO), such as a fractional Chern insulator/quantum Hall state with an s-wave superconductor in order to explore the existence of non-Abelian defects. In order to uncover such defects we must augment the original TO by a $\mathbb{Z}_2$ gauge theory sector coming from the s-wave SC. We first determine the extended TO for a wide variety of fractional quantum Hall or fractional Chern insulator heterostructures. We prove the existence of a general anyon permutation symmetry (AS) that exists in any fermionic Abelian TO state in contact with an s-wave superconductor. Physically this permutation corresponds to adding a fermion to an odd flux vortices (in units of $h/2e$) as they travel around the associated topological (twist) defect. As such, we call it a fermion parity flip AS. We consider twist defects which mutate anyons according to the fermion parity flip symmetry and show that they can be realized at domain walls between distinct gapped edges or interfaces of the TO superconducting state. We analyze the properties of such defects and show that fermion parity flip twist defects are always associated with Majorana zero modes. Our formalism also reproduces known results such as Majorana/parafermionic bound states at superconducting domain walls of topological/Fractional Chern insulators when twist defects are constructed based on charge conjugation symmetry. Finally, we briefly describe more exotic twist liquid phases obtained by gauging the AS where the twist defects become deconfined anyonic excitations.

description: Surface texturing is an effective method to reduce friction without the need to change materials. In this study, surface textures were transferred to rubber samples in the form of dimples, using a novel laser surface texturing (LST)—based texturing during moulding (TDM) production process, developed within the European Project MouldTex. The rubber samples were used to experimentally determine texture-induced friction variations, although, due to the complexity of manufacturing, only a limited amount was available. The tribological friction measurements were hence combined with an artificial intelligence (AI) technique, i.e., Reduced Order Modelling (ROM). ROM allows obtaining a virtual representation of reality through a set of numerical strategies for problem simplification. The ROM model was created to predict the friction outcome under different operating conditions and to find optimised dimple parameters, i.e., depth, diameter and distance, for friction reduction. Moreover, the ROM model was used to evaluate the impact on friction when manufacturing deviations on dimple dimensions were observed. These results enable industrial producers to improve the quality of their products by finding optimised textures and controlling nominal surface texture tolerances prior to the rubber components production.

description: 29th European Photovoltaic Solar Energy Conference and Exhibition; 689-692
description: We present fabrication processes and performances of 239cm² bifacial silicon solar cells based on fullion-
implantation of B, P, or As ions. Thermal annealing strategies are studied to better control the different dopant
profiles and the subsequent FF parameter. Components are passivated with SiO2/SiNx stacks and metallized by
screen-printing. Our SONIA cells result from B/P implants and give up to 20.3% efficiency. COBRA cells result from
B/As doping. These last ones constitute an unprecedented proof of concept in the current PV field. Shallow As-BSF
profiles with low J0BSF values (<150fA/cm²) can be obtained and complete bifacial cells, albeit showing encouraging
performances (>19%), need deepened investigations.

We implemented our wavelet-PAW method as a PAW library in the ABINIT package [http://www.abinit.org] and into BigDFT [http://www.bigdft.org]. We test our implementation in prototypical systems to illustrate the potential usage of our code. By using the wavelet-PAW method, we can simulate charged and special boundary condition systems with frozen-core all-electron precision. Furthermore, our work paves the way to large-scale and potentially order-N simulations within a PAW method.

description: In feature based image matching, distinctive features in images are detected and represented by feature descriptors. Matching is then carried out by assessing the similarity of the descriptors of potentially conjugate points. In this paper, we first shortly discuss the general framework. Then, we review feature detection as well as the determination of affine shape and orientation of local features, before analyzing feature description in more detail. In the feature description review, the general framework of local feature description is presented first. Then, the review discusses the evolution from hand-crafted feature descriptors, e.g. SIFT (Scale Invariant Feature Transform), to machine learning and deep learning based descriptors. The machine learning models, the training loss and the respective training data of learning-based algorithms are looked at in more detail; subsequently the various advantages and challenges of the different approaches are discussed. Finally, we present and assess some current research directions before concluding the paper.

description: We report on our high efficiency n-type metal-wrap-through (MWT) cell and module technology. In
this work, bifacial n-type MWT cells are produced by industrial processes in industrial full-scale and pilot-scale
process equipment. The n-type cells benefit from high recombination lifetime in the wafer and bifaciality. When
combined with MWT technology, high-power back-contact modules result, which can employ also very thin cells.
We will discuss optimization of the MWT contact layout and impact on paste consumption, showing how MWT
technology, like multi-busbar technology, can support very low paste consumption while increasing efficiencies at
the same time. We report a cell conversion efficiency of 21% (in-house measurement on a not conducting, but
reflecting chuck), a significant gain compared to our earlier work.
Full-size modules (60 cells) have been made with power exceeding 300Wp and cell-to-module ratios of the different
I-V parameters are discussed. Modules from cells with average efficiency of 20.9% are pending. This work shows
that low-cost n-type bifacial cells are suitable for industrial high efficiency back-contact technology.

Birdsong dialect patterns explained using magnetic domains

description: The songs and calls of many bird species, like human speech, form distinct regional dialects. We suggest that the process of dialect formation is analogous to the physical process of magnetic domain formation. We take the coastal breeding grounds of the Puget Sound white crowned sparrow as an example. Previous field studies suggest that birds of this species learn multiple songs early in life, and when establishing a territory for the first time, retain one of these dialects in order to match the majority of their neighbours. We introduce a simple lattice model of the process, showing that this matching behaviour can produce single dialect domains provided the death rate of adult birds is sufficiently low. We relate death rate to thermodynamic temperature in magnetic materials, and calculate the critical death rate by analogy with the Ising model. Using parameters consistent with the known behavior of these birds we show that coastal dialect domain shapes may be explained by viewing them as low temperature "stripe states".

description: A good understanding of the ionization rates of neutral species in the heliosphere is important for studies of the heliosphere and planetary atmospheres. So far, the intensities of the ionization reactions have been studied based on observations of the contributing phenomena, such as the solar spectral flux in the EUV band and the flux of the solar wind protons, alpha particles, and electrons. The results strongly depend on absolute calibration of these measurements, which, especially for the EUV measurements, is challenging. Here, we propose a novel method of determining the ionization rate of neutral species based on direct sampling of interstellar neutral gas from two locations in space distant to each other. In particular, we suggest performing observations from the vicinity of Earth's orbit and using ratios of fluxes of ISN He for the direct and indirect orbits of interstellar atoms. We identify the most favorable conditions and observations geometries, suitable for implementation on the forthcoming NASA mission Interstellar Mapping and Acceleration Probe.

description: Agriculture is by far the biggest water consumer on our planet, accounting for 70 per cent of all freshwater withdrawals. Climate change and a growing world population increase pressure on agriculture to use water more efficiently (‘more crop per drop’). Water-use efficiency (WUE) and drought tolerance of crops are complex traits that are determined by many physiological processes whose interplay is not well understood. Here, we describe a combinatorial engineering approach to optimize signalling networks involved in the control of stress tolerance. Screening a large population of combinatorially transformed plant lines, we identified a combination of calcium-dependent protein kinase genes that confers enhanced drought stress tolerance and improved growth under water-limiting conditions. Targeted introduction of this gene combination into plants increased plant survival under drought and enhanced growth under water-limited conditions. Our work provides an efficient strategy for engineering complex signalling networks to improve plant performance under adverse environmental conditions, which does not depend on prior understanding of network function.

description: One first way to reduce solar €/W is to elaborate solar cells reaching high efficiencies using costeffective
processes. The PERT (Passivated Emitter Rear Totally diffused) cell architecture has been developed at
INES on n-type silicon under the name SOLENN20. With this referent process we propose 20% efficient 6inch Cz(n)
solar cells. To make our technology cost-effective we introduce two simplified processes based on co-diffusion.
These processes are applied on high quality wafers coming from 450kg G5 full <100> mono-like ingots, and
resulting from ECM GreenTech and INES previous collaboration. Resulting solar cells performances are
characterized under both forward and reverse bias. The rest of the study concerns the tuning of the co-diffusion step
with a purpose of reducing its impact on bulk quality for narrowing cell efficiency distribution along the ingot.

Anisotropy of X-ray bursts from neutron stars with concave accretion disks

description: Emission from neutron stars and accretion disks in low-mass X-ray binaries is not isotropic. The non-spherical shape of the disk as well as blocking of the neutron star by the disk and vice versa cause the observed flux to depend on the inclination angle of the disk with respect to the line of sight. This is of special importance for the interpretation of Type I X-ray bursts, which are powered by the thermonuclear burning of matter accreted onto the neutron star. Because part of the X-ray burst is reflected off the disk, the observed burst flux depends on the anisotropies for both direct emission from the neutron star and reflection off the disk. This influences measurements of source distance, mass accretion rate, and constraints on the neutron star equation of state. Previous studies made predictions of the anisotropy factor for the total burst flux, assuming a geometrically flat disk. Recently, detailed observations of two exceptionally long bursts (so-called superbursts) allowed for the first time for the direct and the reflected burst flux to each be measured, as opposed to just their sum. The ratio of the reflected and direct flux (the reflection fraction) was much higher than what the anisotropies of a flat disk can account for. We create numerical models to calculate the anisotropy factors for different disk shapes, including concave disks. We present the anisotropy factors of the direct and reflected burst flux separately, as well as the anisotropy of the persistent flux. Reflection fractions substantially larger than unity are produced in case the inner accretion disk steeply increases in height, such that part of the star is blocked from view. Such a geometry could possibly be induced by the X-ray burst, if X-ray heating causes the inner disk to puff up.

description: The precisions of existing gravitational calibrators for gravitational wave observatories are limited by their dependence on the relative position between the calibrators and the observatory's test masses. Here we present a novel geometry consisting of four quadrupole rotors placed at the vertices of a rectangle centered on the test mass. The phases and rotation directions are selected to produce a pseudo plane-wave sinusoidal gravitational acceleration with amplitude of ~ 100 fm/s^2. We show that this acceleration only has minimal dependence on the test mass position relative to the rotor array and can yield 0.15% acceleration amplitude uncertainty while tolerating a 1-cm test mass position uncertainty. The acceleration can be directed precisely along the optical axis of the interferometer arm and applies no torque on the test mass. In addition, the small size of the rotors has significant engineering and safety benefits.

description: We evaluate industrial-type PERC solar cells applying a 5 busbar front grid and fineline-printed Ag
fingers. We obtain finger widths down to 46 μm with stencil printing. This compares to finger widths of 62 μm to 66
μm when applying print-on-print. The 5 busbar front grid (2.5 mm total busbar width) with the best dual print process
reduces the shadowing loss of the front grid to 4.0% compared to 5.8% for a conventional 3 busbar (3.9 mm total
busbar width) front grid printed with print-on-print. The 1.8% reduction in shadowing loss result in equal parts from
the reduced finger width with stencil print as well as from a reduced total busbar width of the 5 busbar design. The
resulting PERC solar cells with 5 busbars demonstrate independently confirmed conversion efficiencies of 21.2%
compared to 20.6% efficiency of the 3 busbar PERC solar cell. The increased conversion efficiency is primarily due
to an increased short circuit current resulting from the reduced shadowing loss. The experimental results agree well
with an analytical model for the front grid related efficiency losses. To our knowledge, 21.2% conversion efficiency
is the highest value reported so far for industry typical silicon solar cells with printed metal front and rear contacts.

description: Uncertainties that exist in nature or due to lack of knowledge have been widely recognized by researchers and engineering practitioners throughout engineering design and analysis for decades. Though great efforts have been devoted to the issues of uncertainty quantification (UQ) in various aspects, the methodologies on the quantification of aleatory uncertainty and epistemic uncertainty are usually logically inconsistent. For instance, the aleatory uncertainty is usually quantified in the framework of probability theory, whereas the epistemic uncertainty is quantified mostly by non-probabilistic methods. In the present paper, a probabilistically consistent framework for the quantification of both aleatory and epistemic uncertainty by synthesizing the probability density evolution method (PDEM) and the change of probability measure (COM) is outlined. The framework is then applied to the backward issues of uncertainty quantification. In particular, the uncertainty model updating issue is discussed in this paper. A numerical example is presented, and the results indicate the flexibility and efficiency of the proposed PDEM-COM framework.
