description: Under light exposure, short-term (~min/hours) and long-term (~hours/days) metastable phenomena are
found in photovoltaic (PV) devices of the amorphous silicon (a-Si:H) technology. The latter is known as the Staebler-
Wronski effect (SWE), which manifests in a light-induced degradation of the performance parameters due to a transient
concentration of deep levels in the band gap of the semiconductor. While the influence of this long-term metastable
(LTM) effect on the module performance is well known, the relevance of short-term metastabilities (STM) on the module
level is rarely discussed. This study focuses on the investigation of the STM effect on the performance parameters of
different double-junction a-Si:H modules at low irradiance levels. The evolution of the module performance was
monitored by taking repetitive IV-curve measurements at open circuit and at optimal load conditions. We found that the
open circuit voltage (VOC), Fill Factor (FF) and the maximum power (PMPP) change considerably under illumination. The
STM effect was found to be completely reversible after storage of the modules in dark. In order to distinguish STM from
LTM effects, an annealing experiment was carried out. We found that the short-term metastable effect is directly
correlated to the defect structure of the investigated modules.

description: Transformer-based pre-trained models have achieved great improvements in semantic matching. However, existing models still suffer from insufficient ability to capture subtle differences. The modification, addition and deletion of words in sentence pairs may make it difficult for the model to predict their relationship. To alleviate this problem, we propose a novel Dual Path Modeling Framework to enhance the model's ability to perceive subtle differences in sentence pairs by separately modeling affinity and difference semantics. Based on dual-path modeling framework we design the Dual Path Modeling Network (DPM-Net) to recognize semantic relations. And we conduct extensive experiments on 10 well-studied semantic matching and robustness test datasets, and the experimental results show that our proposed method achieves consistent improvements over baselines.

description: Hydrogenated microcrystalline silicon oxide (μc-SiOx:H) was developed and implemented as a contact
layer in hydrogenated amorphous thin film silicon (a-Si:H) single junction solar cells. Higher transparency, sufficient
electrical conductivity, low ohmic contact to sputtered ZnO:Al and tunable refractive index make p-type μc-SiOx:H a
promising alternative to the commonly used p-type μc-Si:H contact layers. In this work p-type μc-SiOx:H layers were
fabricated with a conductivity up to the order of 10-2 S/cm and over 60% Raman crystallinity. Furthermore, we
present p-type μc-SiOx:H with a broad range over which the optical properties (band gap E04 and refractive index n)
can be tuned (2.1 eV < E04 < 2.8 eV and 1.6 < n < 2.6) by adapting deposition parameters like CO2/SiH4 ratio in the
gas mixture. a-Si:H solar cells were produced with an conversion efficiency improvement from 9.4 to 9.7% by using
p-type μc-SiOx:H compared to standard p-type μc-Si:H contact layer.

description: The recently proposed Skordis-Złośnik theory is the first relativistic MOND theory that can recover the success of the standard $Λ$CDM model at matching observations of the cosmic microwave background. This paper aims to revisit the Newtonian and MOND approximations and the gravitational wave analysis of the theory. For the local gravitational parameters, we show that one could obtain both time-varying effective Newtonian gravitational \textit{constant} $G_\textrm{N}$ and time-varying characteristic MOND acceleration scale $a_\textrm{MOND}$, by relaxing the static assumption extensively adopted in the literature. Specially, we successfully demonstrate how to reproduce the redshift dependence of $a_\textrm{MOND}$ observed in the \textit{Magneticum} cold dark matter simulations. For the gravitational waves, we show that there are only two tensor polarizations, and reconfirm that its speed is equal to the speed of light.

description: As an important area, silicon thin film solar technology had made tremendous progress in the past five
years. Especially, the introduction and commercialization of amorphous and microcrystalline silicon tandem thin film
technology has made possible the conversion efficiency in mass production over 10%. In past several years, Chint
Solar (Astronergy), one of the fewer silicon thin film PV manufacturers still in active production, had carried out
extensive R&D programs involving fabrication technology improvement, new products development, unique
application of thin film products and the optimization of energy out in the field et al. As a critical part in the silicon
thin film solar cells, the front (window) and back electrodes (backside metallization) play the key role in light
management and reduction of electrical loss. This presentation will first made a comparison study on the performance
of two major transparent conducting oxides (TCOs), aluminum doped zinc oxide (AZO) and boron doped zinc oxides
(BZO), as front electrodes (window). Then the impact of front electrodes on the selection of backside electrodes for
silicon tandem solar cell will be discussed. Overall it is concluded that AZO and BZO gives different trapping
capability for different part of the solar spectrum, and front electrodes has significant impact on the selection of
backside electrodes.

description: The electron mass in atomic mass units has been determined with a relative uncertainty of $2.8\cdot 10^{-11}$, which represents a 13-fold improvement of the 2010 CODATA value. The underlying measurement principle combines a high-precision measurement of the Larmor-to-cyclotron frequency ratio on a single hydrogen-like carbon ion in a Penning trap with a corresponding very accurate $g$-factor calculation. Here, we present the measurement results in detail, including a comprehensive discussion of the systematic shifts and their uncertainties. A special focus is set on the various sources of phase jitters, which are essential for the understanding of the applied line-shape model for the $g$-factor resonance.

description: Understanding and controlling light induced degradation in amorphous Si solar cells have been
challenging subjects in photovoltaic science fields. We have investigated the degradation behavior of device
properties with varying structures in pin type amorphous Si solar cells, to reveal following issues. (1) Can the light
induced degradation be suppressed by simply scaling absorber thickness in principle? (2) If the light induced
degradation cannot be completely suppressed by simple absorber scaling, can we further suppress the degradation by
changing other device structures? We found that the light induced degradation cannot be completely suppressed by
simple scaling of the absorber, and there is an additional degradation mechanism independent of absorber thickness.
Finally, we present a thin film solar cell with a surface-depleted transparent electrode, which is shown to be effective
in further reduction of light induced degradation.

description: We present GTC-10.4m spectroscopy and multi-band photometry of the faint (r ~26) optical counterpart of the anomalous X-ray pulsar 4U 0142+61. The 5000 - 9000 Angs spectrum -- the first obtained for a magnetar -- is featureless, allowing us to set an equivalent width upper limit EW < 25 Angs to the presence of emission lines in the Halfa region. Multi-band photometry in the g, r, i, z SDSS bands obtained at different epochs over 12 years shows no significant variability from minutes-to-years time scales. The photometry has been calibrated, for the first time, against the SDSS itself, resulting in solid upper limits to variability ranging from ~0.2 mag in i (over 12 years) to 0.05 mag in z (over 1.5 years). The shape of the optical + near-infrared (literature values) spectral energy distribution is not well constrained due to the high extinction along the line of sight. Using a Markov Chain Monte Carlo analysis we find that it can be described by a power-law with a spectral index beta=-0.7+-0.5 and E_(B-V)=1.5+-0.4. We also discuss on the implications of adding hard X-ray flux values from literature to the spectral fitting.

description: The power-law emission and reflection component provide valuable insights into the accretion process around a black hole. In this work, thanks to the broadband spectra coverage of \emph{the Nuclear Spectroscopic Telescope Array}, we study the spectral properties for a sample of low-mass black hole X-ray binaries (BHXRBs). We find that there is a positive correlation between the photon index $Γ$ and the reflection fraction $R$ (the ratio of the coronal intensity that illuminates the disk to the coronal intensity that reaches the observer), consistent with previous studies, but except for MAXI J1820+070. It is quite interesting that this source also deviates from the well-known ``V"-shaped correlation between the photon index $Γ$ and the X-ray luminosity log$L_{\rm X}$, when it is in the bright hard state. More specifically, the $Λ$-shaped correlation between $Γ$ and log$L_{\rm X}$ is observed, as the luminosity decreases by a factor of 3 in a narrow range from $\sim 10^{38}$ to $10^{37.5}$ $\rm erg~s^{-1}$. Furthermore, we discover a strong positive correlation between $R$ and the X-ray luminosity for BHXRBs in the hard state, which puts a constraint on the disk-corona coupling and the evolution.

description: In this paper, a robust adaptive type-2 fuzzy higher order sliding mode controller is designed to stabilize the unstable periodic orbits of uncertain perturbed chaotic system with internal parameter uncertainties and external disturbances. In Higher Order Sliding Mode Control (HOSMC),the chattering phenomena of the control effort is reduced, by using Super Twisting algorithm. Adaptive interval type-2 fuzzy systems are proposed to approximate the unknown part of uncertain chaotic system and to generate the Super Twisting signals. Based on Lyapunov criterion, adaptation laws are derived and the closed loop system stability is guaranteed. An illustrative example is given to demonstrate the effectiveness of the proposed controller.

description: The tensile tests of a-Si/a-SiGe flexible solar cells were carried out. Mechanical damage was
characterized by acoustic emission (AE) technique and lock-in thermography (LT). The leak current was also
monitored as a measure of the electrical performance degradation. The leak current rapidly increased at the strain of
~1.4 %, and it was observed by LT that the temperature modulation around a penetrating hole increased critically.
The AE technique detected damages earlier than the increase in the leak current, which indicated that the AE
technique was more sensitive to damage than the leak current measurement. Especially, the AE sensor attached on the
penetrating hole detected AE signals earlier than the others. It is suggested by LT and AE technique that the increase
in the leak current was derived from the microdamage accumulation around the penetrating holes. Furthermore, the
detailed observation around a penetrating hole demonstrated that the dominant damages around the holes were
microcracks perpendicular to the loading direction. Consequently, the failure process in flexible solar cells was well
characterized by the LT, AE technique and in-situ observation.

description: Recent work by Webb {\it et al.} has provided indications of spatial variations of the fine-structure constant, $α$, at a level of a few parts per million. Using a dataset of 293 archival measurements, they further show that a dipole provides a statistically good fit to the data, a result subsequently confirmed by other authors. Here we show that a more recent dataset of dedicated measurements further constrains these variations: although there are only 10 such measurements, their uncertainties are considerably smaller. We find that a dipolar variation is still a good fit to the combined dataset, but the amplitude of such a dipole must be somewhat smaller: $8.1\pm1.7$ ppm for the full dataset, versus $9.4\pm2.2$ ppm for the Webb {\it et al.} data alone, both at the $68.3\%$ confidence level. Constraints on the direction on the sky of such a dipole are also significantly improved. On the other hand the data can't yet discriminate between a pure spatial dipole and one with an additional redshift dependence.

description: A common approach to improve the performance of thin-film photovoltaic devices is to build
multijunction cells consisting of two or more monolithically stacked cells that typically utilize absorbers exhibiting
different bandgaps. A widespread low bandgap material used in silicon based multijunction concepts is
microcrystalline silicon (μc-Si:H). However, this material exhibits a comparably low absorption coefficient, resulting
in a demand for high absorber thicknesses and hence long deposition times. An alternative group IV semiconductor is
amorphous germanium (a-Ge:H) with a bandgap similar to that of μc-Si:H but an absorption coefficient which is
higher by more than one order of magnitude. However, a drawback of this material is its comparably low material
quality in terms of defect density. In this contribution, coupled optical and electrical simulations are presented,
showing that the problem of low material quality will be overcome by using extremely low absorber thicknesses.

description: System induced degradation can occur depending on the system design of PV power plants. In case of
amorphous silicon solar modules this causes e.g. a diffusion of sodium ions from the cover glass into the TCO front
contact, followed by a chemical reaction that leads to an irreversible power loss and is called TCO corrosion.
Leakage currents between the cover glass and the electrical connectors can be used as an indicator of the corrosion
rate. It is state-of-the-art that a negative potential of the TCO layer in respect to the cover class (resp. mounting
structure) can have an impact on the corrosion process. To avoid corrosion the negative DC pole of the PV generator
has to be grounded. Thus a positive potential occurs between the TCO layer and the cover glass and the positive
charged sodium ions do not migrate into the TCO layer. In contrast to this, the results of this study (amongst others)
show that a degradation can occur for positive potentials, too. Consequently the basic objective of this paper is the
analysis of the degradation mode and the leakage currents according to the grounding situation of amorphous silicon
solar modules under outdoor conditions. For this purpose nine amorphous silicon solar modules were mounted with
different mounting systems, like back rails and module clamps. Furthermore, an external voltage with negative and
positive bias is applied between the mounting system and the short-circuited module connectors. Additionally, the
influence of an AC potential is investigated. The leakage currents were measured and logged continuously.

description: Liquid processed, single-phase, highly crystalline quaternary alloy of CZTSe comprising of earth-abundant
and non-toxic elements Zn & Sn can be synthesized by using non-vacuum hot-injection method through careful tuning of
the precursor ratios of Zn & Sn without resorting to post-synthesis selenization or high temperature methods. However,
the method results in the highly crystalline phase formation with the absence of any conspicuous binary or ternary related
peaks. Usage of the organic capping agents TOP/TOPO has been reported for the first time in the synthesis of CZTSe
nanocrystals. The variations of bandgap value with Zn:Sn ratio together with associated changes observed in the crystal
structure and morphology demonstrates that CZTSe has tolerance to large –off stoichiometries since grain boundaries are
inactive. CZTSe nanocrystallites with higher Zn concentration ~ 80 at.% are besotted with band gap values ~ 1.2 eV and
reduced interplanar distance and are deemed suitable for highly efficient CZTSe nanocrystal PV devices.
The restframe ultraviolet of superluminous supernovae -- I. Potential as cosmological probes

description: Superluminous supernovae (SLSNe) have been detected to $z\sim4$ and can be detected to $z\gtrsim15$ using current and upcoming facilities. SLSNe are extremely UV luminous, and hence objects at $z\gtrsim7$ are detected exclusively via their rest-frame UV using optical and infrared facilities. SLSNe have great utility in multiple areas of stellar and galactic evolution. Here, we explore the potential use of SLSNe type-I as high-redshift cosmological distance indicators in their rest-frame UV. Using a SLSNe-I sample in the redshift range $1\lesssim z\lesssim 3$, we investigate correlations between the peak absolute magnitude in a synthetic UV filter centered at 250 nm and rise time, colour and decline rate of SLSNe-I light curves. We observe a linear correlation between $M_0(250)$ and the rise time with an intrinsic scatter of 0.29. Interestingly, this correlation is further tightened ($σ_{int} \approx 0.2$) by eliminating those SLSNe which show a pre-peak bump in their light curve. This result hints at the possibility that the "bumpy" SLSNe could belong to a different population. Weak correlations are observed between the peak luminosity and colour indices. No relationship is found between UV peak magnitude and the decline rate in contrast to what is typically found in optical band. The correlations found here are promising, and give encouraging insights for the use of SLSNe as cosmological probes at high redshifts using standardising relations in the UV. We also highlight the importance of early, and consistent, photometric data for constraining the light curve properties.

description: The capability of the admittance spectroscopy and new method, which is based on bias dependent
photoresponse measurements for defect characterization in p-i-n a-Si:H solar cells was demonstrated. An
experimental study of TCO/(p)a-SiC:H/(i)a-SiC:H/(i)a-Si:H/(n)a-Si:H/TCO solar cells on glass substrate was
performed by the proposed techniques. The responses of DOS in (i)a-Si:H layer and a-SiС:H layers placed in p-area
of structure were detected by admittance spectroscopy. The value of DOS in mid gap of (i)a-Si:H layer equal to
5×1016 cm-3 eV-1 was estimated. It was shown that the photoinduced degradation of p-i-n solar cells during 705 hours
(AM1.5 100 mW/cm2) leads to increase of DOS to the values about 1017 cm-3eV-1. The observed response of DOS in
valence band tails for a-SiС:H wide band-gap layers allowed to estimate the lower limit of DOS at the Fermi level
(1018 cm-3 eV-1) and to determine the position of the Fermi level being 0.4 eV above valence band edge. Compatible
results were obtained by bias dependent photoresponse measurements. DOS in mid gap of (i)a-Si:H layer being
1-2×1016 and 5×1016 cm-3eV-1 for initial and light soaked cells, respectively, were estimated by this method.

The Sine$_β$ operator

description: We show that Sine$_β$, the bulk limit of the Gaussian $β$-ensembles is the spectrum of a self-adjoint random differential operator \[ f\to 2 {R_t^{-1}} \left[ \begin{array}{cc} 0 &-\tfrac{d}{dt} \tfrac{d}{dt} &0 \end{array} \right] f, \qquad f:[0,1)\to \mathbb R^2, \] where $R_t$ is the positive definite matrix representation of hyperbolic Brownian motion with variance $4/β$ in logarithmic time. The result connects the Montgomery-Dyson conjecture about the Sine$_2$ process and the non-trivial zeros of the Riemann zeta function, the Hilbert-Pólya conjecture and de Brange's attempt to prove the Riemann hypothesis. We identify the Brownian carousel as the Sturm-Liouville phase function of this operator. We provide similar operator representations for several other finite dimensional random ensembles and their limits: finite unitary or orthogonal ensembles, Hua-Pickrell ensembles and their limits, hard-edge $β$-ensembles, as well as the Schrödinger point process. In this more general setting, hyperbolic Brownian motion is replaced by a random walk or Brownian motion on the affine group. Our approach provides a unified framework to study $β$-ensembles that has so far been missing in the literature. In particular, we connect Itô's classification of affine Brownian motions with the classification of limits of random matrix ensembles.

description: In this work we use and further elaborate a model which has previously been proposed to model the performance of a-Si based devices under real operation conditions. The model focuses on days of clear-sky conditions and on four main losses/gain mechanism only: (1) temperature, (2) spectral-effects, (3) reflection losses, and (4) stabler-wronsky effects (SWE). Input for our simulations are daily aggregate data weighted on the irradiance profile for the Air Mass AM, the module’s temperature Tmod, and the Angle-of-Incidence AOI. SWE for our geographical area is modeled using inputs from former works. From the module side the model requires a very limited characterization of the device under test: IV measurement at STC, temperature coefficients, spectral response and angle-of-incidence.
The model agrees very well in describing the energy performance of the a-Si device tested under real operation conditions. Slightly discrepancies from the model on the long run are attributed to an intrinsic degradation of the module’s performance. An extension of the model as a tool for energy yield forecasting and to cover different locations, typologies of installation (e.g. BIPV) and to consider other technologies will be the subject of further research.
Impact parameter dependence of pion ratio in probing the nuclear symmetry energy using heavy-ion collisions

description: The impact parameter dependence of \rpi ratio is examined in heavy-ion collisions at 400MeV/nucleon within a transport model. It is shown that the sensitivity of \rpi ratio on symmetry energy shows a transition from central to peripheral collisions, i.e., the stiffer symmetry energy leads to a larger \rpi ratio in peripheral collisions while the softer symmetry energy always leads this ratio to be larger in central collisions. After checking the kinematic energy distribution of \rpi ratio, we found this transition of sensitivity of \rpi ratio to symmetry energy is mainly from less energetic pions, i.e., the softer symmetry energy gets the less energetic pions to form a smaller \rpi ratio in peripheral collisions while these pions generate a larger \rpi ratio in central collisions. Undoubtedly, the softer symmetry energy can also lead more energetic pions to form a larger \rpi ratio in peripheral collisions. Nevertheless, considering that most of pions are insufficient energetic at this beam energy, we therefore suggest the \rpi ratio as a probe of the high-density symmetry energy effective only in central at most to midcentral collisions, thereby avoiding the possible information of low-density symmetry energy carried in \rpi ratio from peripheral collisions.

description: The light-induced degradation of -Si:H/μc-Si:H solar cells with the initial efficiency of 10.4 – 10.6 %
at temperatures of 298, 328 and 353 K and the incident radiation flux density from 1 to 10 kW/m² (AM1.5G) has
been investigated. It has been established that the saturation level of the photo-induced degradation for the
investigated structures depends essentially on the cell temperature and is practically invariant to the light irradiation
intensity. The solar cell efficiency drop degree at a prolonged light exposure is 1.0 – 1.4 % at temperature of
298 K, 0.2% - at 328 K. At 353 K, the degradation is completely suppressed. From the experimental spectral and
current – voltage characteristics of solar cells, the nonequilibrium charge carrier lifetime values have been
determined, and variations of the concentration of dangling (broken) bonds in the i--Si:H and i-μc-Si:H layers have
been calculated. Approximation of the dependencies was performed by the modified “H-collision” model. The
calculated values of the dangling bond concentrations at different temperatures and exposure durations were used in
simulating the dependencies of solar cell parameters on the light soaking time. The results obtained have shown a
good fit of the rated rates of current and efficiency degradation of the investigated tandem solar cells to the
experimental data.
Resolving the structure of TiBe$_{12}$

description: There has been considerable controversy regarding the structure of TiBe$_{12}$, which is variously reported as hexagonal and tetragonal. Lattice dynamics simulations based on density functional theory show the tetragonal phase space group $I4/mmm$ to be more stable over all temperatures, while the hexagonal phase exhibits an imaginary phonon mode, which, if followed, would lead to the cell adopting the tetragonal structure. We then report the predicted ground state elastic constants and temperature dependence of the bulk modulus and thermal expansion for the tetragonal phase.

Probing the rapid formation of black holes and their galaxy hosts in QSOs

description: Using the modelling code X-CIGALE, we reproduced the SEDs of 1,359 SDSS QSOs within the redshift range 0 < z < 4, for which we have NIR/MIR fluxes with the highest quality and spectral data characterizing their SMBHs. Consistent with a rapid formation of the host galaxies, the star formation histories (SFHs) have small e-folding, at most 750 Myrs using an SFH function for Spiral or 1000 Myrs using one for Elliptical. Above z \sim 1.6, the two solutions are degenerate, the SEDs being dominated by the AGN continuum and high star formation rates (SFRs), typical of starburst galaxies, while at lower redshifts the starburst nature of the host, independent from its morphology, is better reproduced by an Spiral SFH. In general, the SFR increases with the redshift, the mass of the bulge, the AGN luminosity and Eddington ratio, suggesting there is no evidence of AGN quenching of star formation. Comparing the specific BHAR with specific SFR, all the QSOs at any redshift trace a linear sequence below the Eddington luminosity, in parallel and above the one-to-one relation, implying that QSOs are in a special phase of evolution during which the growth in mass of their SMBH is more rapid than the growth in mass of their galaxy hosts. This particular phase is consistent with a scenario where the galaxy hosts of QSOs in the past grew in mass more rapidly than their SMBHs, suggesting that a high star formation efficiency during their formation was responsible in limiting their masses

description: The use of ‘doped silicon oxide based microcrystalline’ material as a potential candidate for costeffective
and reliable back reflector layer (BRL) for single junction a-Si solar cell and intermediate reflecting layer
(IRL) for micromorph double tandem solar cells is discussed in this article. The doped μc-SiO:H layers with a
refractive index close to 2 and with suitable electrical properties were fabricated by radio frequency plasma enhanced
chemical vapor deposition (RF-PECVD) technique, using the conventional capacitively coupled reactors.
Optoelectronic properties of these layers were controlled by varying the oxygen content within the film. The
performance of these layers as BRL have been investigated by incorporating them in a single junction amorphous
silicon solar cells and the results are compared with those of the conventional ZnO:Al BRL based cell. The main
advantage with this technique is that it can avoid an ex situ deposition of ZnO:Al, by using doped SiO:H based
material deposited in the same reactor and with the same process gases as used for thin-film silicon solar cells. Initial
single junction a-Si solar cell efficiency of 9.12% (Voc = 0.88 V, FF = 0.70, Current density = 14.90 mA/cm2) is
achieved by using doped μc-SiO:H based material as a back reflector is very similar to that obtained by using
conventional ZnO/Al BRL. Thus it will be possible to replace the ex-situ back reflector which will reduce the cost as
well as make the fabrication process simpler.
Hadronic resonances enhanced by thresholds

description: We present a neat example of a meson--baryon system where the vicinity of two different thresholds enhances the binding of a hadronic resonance, a pentaquark. As a consequence the pattern of states may change when moving among different flavor sectors, what poses a warning on naive extrapolations to heavy flavor sectors based on systematic expansions. For this purpose we simultaneously analyze the $N\bar D$ and $NB$ two-hadron systems looking for possible bound states or resonances. When a resonance is controlled by a coupled-channel effect, going to a different flavor sector may enhance or diminish the binding. This effect may, for example, generate significant differences between the charmonium and bottomonium spectra above open-flavor thresholds or pentaquark states in the open-charm and open-bottom sectors.
