description: People with stress and anxiety about response time (RT) management experience difficulties in talking with others online, causing situational communication apprehension and a fear of negative evaluation (FNE). Reducing stress and anxiety about RT management will provide them ease of talk. In this paper, to reduce stress and anxiety in RT management, we propose a system involving a teleoperated avatar agent and its supporting agent with interactive responses adaptive to RT variations for communication in video conferences, referred to as the proposed system. The proposed system was compared with another system involving only an avatar agent as a communication channel without interactive responses, referred to as the conventional system. In the video-based and field experiments, a human interviewer and interviewee discussed paying taxes and earning unethical money using the proposed and conventional systems; where situational communication apprehension measure (SCAM), FNE, and sense of being attended (SoBA) were measured indices. The proposed system with interactive responses adaptive to RT variations reduced the stress and anxiety of RT management significantly. A significant reduction in SCAM and FNE and an increase in SoBA scores were observed for the proposed system, as compared to the conventional system, for the video-based and field experiments.

description: Mobile Ad-hoc Network (MANET) is a distributed, decentralized network of wireless portable nodes connecting directly without any fixed communication base station or centralized administration. Nodes in MANET move continuously in random directions and follow an arbitrary manner, which presents numerous challenges to these networks and make them more susceptible to different security threats. Due to this decentralized nature of their overall architecture, combined with the limitation of hardware resources, those infrastructure-less networks are more susceptible to different security attacks such as black hole attack, network partition, node selfishness, and Denial of Service (DoS) attacks. This work aims to present, investigate, and design an intrusion detection predictive technique for Mobile Ad hoc networks using deep learning artificial neural networks (ANNs). A simulation-based evaluation and a deep ANNs modelling for detecting and isolating a Denial of Service (DoS) attack are presented to improve the overall security level of Mobile ad hoc networks.

description: This paper deals with the possibility of automated detection of defective solar modules by thermovision camera mounted on a dron or on the car roof. During thermovision imaging analysis of large photovoltaic power plants there are captured large numbers of images. These images are analyzed by human operators. Given the vast amount of images, which are sometimes very similar, and given of the specificity of some defects, the work of operators can be replaced by the automation recognizing of anomalies software. Two methods for the automatic detection of defects in thermal imaging pictures were developed and validated. First one method is based on the geometric information of tested modules and on the assumption that defective cell has an increased temperature along its whole surface and therefore will appear as a regular geometric shape which is recognizable by geometric comparisons. The second method does recognition by usage of trained artificial neural network.

description: In this paper we investigate the effects of the potential induced degradation (PID) in bifacial N-type
solar cells (BSC) using different encapsulation materials. Three different approaches were used for the encapsulation:
(i) two sheets of polyolefin elastomer type I (POE-I) in the front and one sheet of POE-I in the back of the solar cell
(A-type), (ii) two sheets of POE-I in the front and one sheet of ethylene-vinyl-acetate (EVA) in the back of the solar
cell (B-type) and (iii) one sheet of polyolefin elastomer type II (POE-II) in the front and one sheet of ethylene-vinylacetate
(EVA) in the back of the solar cell (C-type). Within this work, we show how the use of different
encapsulation structures may strongly affect the robustness to PID. Moreover the results demonstrate that, after 55
hours of PID, the A-type and B-type configurations show similar degradation of the maximum power (26.5%)
whereas the C-Type configuration shows a considerable improvement in the PID reliability (maximum power
degradation of 1.5%). The analysis of the recovery phase shows that PID degradation is mainly recoverable and that
it can be recovered by applying a reverse voltage with respect to the PID stress.

description: In this paper, several solutions against PID have been tested on mini-modules then 60-cell modules.
4 encapsulants are compared at the mini-module level: two types of ethylene-vinyl acetate (EVA), a thermoplastic
polyolefin (TPO) and an ionomer. Then 3 out of 4 encapsulants are compared on 60-cell modules in this study: an
ethylene-vinyl acetate (EVA), a thermoplastic polyolefin (TPO) and an ionomer.
3 modules architectures have been also tested: a module with a standard glass and a TPT backsheet, a module with a
special thin glass and a TPT backsheet, and a special thin double glass module using the same thin glass (only on 60-cell
module).
At the end, a module with ion implanted cells, while others components were kept identical, is PID tested.
The applied voltage was 1500V in order to prepare the future increase of DC plant voltage. On mini-modules, a first PID
test at room temperature (25°C and Al-foil) has been conducted before a more severe test at 70°C (Al foil), allowing us
to clearly differentiate the influence of the tested materials on PID degradation of the modules.
The conditions of these tests on 60-cell modules were 192 hours 75°C 85RH. Contrary to EVA and standard glass
modules, we clearly observed no degradation on thermoplastic polyolefin (TPO), ionomer, thin glass modules and
module with ion implanted cells. Using one of these components is a solution against PID.

Real Space Renormalization Group Theory of Disordered Models of Glasses

description: We develop a real space renormalisation group analysis of disordered models of glasses, in particular of the spin models at the origin of the Random First Order Transition theory. We find three fixed points respectively associated to the liquid state, to the critical behavior and to the glass state. The latter two are zero-temperature ones; this provides a natural explanation of the growth of effective activation energy scale and the concomitant huge increase of relaxation time approaching the glass transition. The lower critical dimension depends on the nature of the interacting degrees of freedom and is higher than three for all models. This does not prevent three dimensional systems from being glassy. Indeed, we find that their renormalisation group flow is affected by the fixed points existing in higher dimension and in consequence is non-trivial. Within our theoretical framework the glass transition results to be an avoided phase transition.

description: A new work item IEC NP 62804-02 TS was submitted in order to define a procedure for evaluating
effects of potential-induced degradation (PID) on thin-film PV modules. This work seeks to answer the question of
how many years of outdoor service life are covered by the proposed IEC PID test procedure, applying the assumption
that an equivalent transferred charge implies an equivalent severity of the PID stress. The leakage currents and
transferred charge from cell to ground for a standard CIGS module configuration and a leakage current suppression
(LCS) CIGS module configuration were evaluated in an environmental chamber test and in the outdoor field in
Germany. The suppression of currents with the LCS configuration works very efficiently at elevated temperatures
(also for the IEC test condition) but can be neglected for cool and extremely wet outdoor conditions. Comparing
transferred charge in the field, based on a selected and not necessarily representative day, with the transferred charge
in the 1,000 h IEC test procedure we conclude that the IEC test covers more than 50 years of service life in Germany
for the standard system, but less than 2 years for the LCS configuration. Thus no generally valid equivalence between
the severity of the PID stress induced by the new IEC test and the stress during a full service life can be established.

description: Provided the quantum fluctuations are amplified in the presence of a classical gauge field configuration the resulting curvature perturbations exhibit a mild statistical anisotropy which should be sufficiently weak not to conflict with current observational data. The curvature power spectra induced by weakly anisotropic initial states are computed here for the first time when the electric and the magnetic gauge couplings evolve at different rates as it happens, for instance, in the relativistic theory of van der Waals interactions. After recovering the results valid for coincident gauge couplings, the constraints imposed by the isotropy and the homogeneity of the initial states are discussed. The obtained bounds turn out to be more stringent than naively expected and cannot be ignored when discussing the underlying magnetogenesis scenarios.

description: A common problem to be solved during the operation of photovoltaic (PV) power plants is early
detection of PV modules defects. Usual methods are based on both measurement of electric parameters and
visualization of possible defects (thermography). The common electric measurement usually doesn’t show the initial
damage like less serious cracks inside the module. For these purposes is necessary to use some advanced
visualization method like electroluminescence. But this requires either special equipment or the dark chamber. In this
text is presented a new approach to revealing the hidden defects using impedance spectroscopy. The results of
measurement are presented as well as comparison between the individual methods.

description: A proposal of electrically controlled spin transistor in helical magnetic field is presented. In the proposed device, the transistor action is driven by the Landau-Zener transitions that lead to a backscattering of spin polarized electrons and switching the transistor into the high-resistance state (off state). The on/off state of the transistor can be controlled by the all-electric means using Rashba spin-orbit coupling that can be tuned by the voltages applied to the side electrodes.

description: The ray-tracing optical simulation model was used to analyze several optical structures, which
constructed on ribbon inside photovoltaic module. Two kinds of optical structures, groove-like & diffuse white, were
analyzed with indoor and outdoor conditions. For groove-like structure, the outdoor performance was correlative to
mounting configurations of module, portrait and landscape. Moreover, such results were strongly depended on
different seasons. For diffuse white optical structure constructed on ribbon, significant difference was shown during
simulation with outdoor condition when compared with groove-like structure. But diffuse white structure was poor
than groove-like structure about the efficiency of light capture. Three kinds of full-size photovoltaic modules (60-
cells), groove-like structure mounting with portrait and landscape configuration, and diffuse-white structure mounting
with portrait configurations, were produced and examined in practical field during summer. The results of field test
matched well with ray-tracing optical simulation.

description: Visual discrimination of clinical tissue types remains challenging, with traditional RGB imaging providing limited contrast for such tasks. Hyperspectral imaging (HSI) is a promising technology providing rich spectral information that can extend far beyond three-channel RGB imaging. Moreover, recently developed snapshot HSI cameras enable real-time imaging with significant potential for clinical applications. Despite this, the investigation into the relative performance of HSI over RGB imaging for semantic segmentation purposes has been limited, particularly in the context of medical imaging. Here we compare the performance of state-of-the-art deep learning image segmentation methods when trained on hyperspectral images, RGB images, hyperspectral pixels (minus spatial context), and RGB pixels (disregarding spatial context). To achieve this, we employ the recently released Oral and Dental Spectral Image Database (ODSI-DB), which consists of 215 manually segmented dental reflectance spectral images with 35 different classes across 30 human subjects. The recent development of snapshot HSI cameras has made real-time clinical HSI a distinct possibility, though successful application requires a comprehensive understanding of the additional information HSI offers. Our work highlights the relative importance of spectral resolution, spectral range, and spatial information to both guide the development of HSI cameras and inform future clinical HSI applications.

description: The mounting system of photovoltaic (PV) modules has a significant impact on the thermo-mechanical
stress in PV modules. In this work the clamping of framed PV modules is compared to the clamping of unframed PV
laminates by a simulation study using the finite element method (FEM). The FEM modelling allows to calculate the
local stress distribution in the solar cells directly. We present results from a model of a standard glass-backsheet PV
module with 3 mm glass under homogenous mechanical pressure load of up to 5400 Pa. The thermal stress from the
lamination process is considered as a pre-study, similar to [1]. The frameless clamped PV laminate shows a
significantly larger displacement of 147 mm than the framed PV module with 54 mm for 2400 Pa. In line with the
findings of Kajari-Schroeder [2] we simulate an elliptic deflection distribution for the framed PV module, whereas
the clamped PV laminate shows a wave-like shape. Consequently, the area of high tensile stresses in the silicon solar
cells, with a maximum value of 142 MPa at 2400 Pa load, is narrowly located around the highest curvature at the
center of the framed PV module. In case of the frameless clamped PV laminate we identify four areas of high tensile
stresses with a higher maximum value of 218 MPa. The results show that the frame reduces the tensile stresses in the
solar cells significantly compared to unframed laminates.

description: A fast and non-destructive failure inspection is essential to ensure the reliability of PV plants. This might only be achieved by using highly sensitive imaging techniques which can detect local electrical losses in solar modules. Here, EL imaging used for outdoor PV inspection gained large interest, since it can be used to characterize local cell damages, series resistances, and shunts in solar modules. However, currently available EL-cameras base on Si-CCD-detectors. Besides high spatial resolutions they exhibit long image integration times (IIT) of about 1 s for obtaining evaluable EL-images. To overcome this limitation we present, for the first time, an InGaAs camera which enables a complete EL-characterization of field-installed PV-modules with IITs between 1 ms and 20 ms. The short IITs result in frame rates of about 100 Hz which even offer the opportunity of recording dynamic EL-movies and daylight Electroluminescence Lock-In (ELLI) measurements. To test the outdoor applicability we compared EL-movies of the InGaAs camera with EL-images of a Si-CCD camera and show that all relevant power reducing cell failures (e. g. cracks) can be detected and characterized.

description: The main scientific goal of TESS is to find planets smaller than Neptune around stars that are bright enough to allow for further characterization studies. Given our current instrumentation and detection biases, M dwarfs are prime targets in the search for small planets that are in (or near) the habitable zone of their host star. In this work, we use photometric observations and CARMENES radial velocity measurements to validate a pair of transiting planet candidates found by TESS. The data were fitted simultaneously, using a Bayesian Markov chain Monte Carlo (MCMC) procedure and taking into account the stellar variability present in the photometric and spectroscopic time series. We confirm the planetary origin of the two transiting candidates orbiting around TOI-2095 (LSPM J1902+7525). The star is a nearby M dwarf ($d = 41.90 \pm 0.03$ pc, $T_{\rm eff} = 3759 \pm 87$ K, $V = 12.6$ mag), with a stellar mass and radius of $M_\star = 0.44 \pm 0.02 \; M_\odot$ and $R_\star = 0.44 \pm 0.02 \; R_\odot$, respectively. The planetary system is composed of two transiting planets: TOI-2095b, with an orbital period of $P_b = 17.66484 \pm (7\times 10^{-5})$ days, and TOI-2095c, with $P_c = 28.17232 \pm (14\times 10^{-5})$ days. Both planets have similar sizes with $R_b = 1.25 \pm 0.07 \; R_\oplus$ and $R_c = 1.33 \pm 0.08 \; R_\oplus$ for planet b and planet c, respectively. Although we did not detect the induced RV variations of any planet with significance, our CARMENES data allow us to set stringent upper limits on the masses of these objects. We find $M_b < 4.1 \; M_\oplus$ for the inner and $M_c < 7.4 \; M_\oplus$ for the outer planet (95% confidence level). These two planets present equilibrium temperatures in the range of 300-350 K and are close to the inner edge of the habitable zone of their star.

description: This paper discusses tension-compression asymmetry properties of Ogden hyperelastic formulations. It is shown that if all negative or all positive Ogden coefficients are used, tension-compression asymmetry occurs the degree of which cannot be separately controlled from the degree of non-linearity. A simple hybrid form is therefore proposed providing separate control over the tension-compression asymmetry. It is demonstrated how this form relates to a newly introduced generalised strain tensor class which encompasses both the tension-compression asymmetric Seth-Hill strain class and the tension-compression symmetric Bažant strain class. If the control parameter is set to q=0.5 a tension-compression symmetric form involving Bažant strains is obtained with the property Ψ(λ_1,λ_2,λ_3 )=Ψ(1/λ_1 ,1/λ_2 ,1/λ_3 ). The symmetric form may be desirable for the definition of ground matrix contributions in soft tissue modelling allowing all deviation from the symmetry to stem solely from fibrous reinforcement. Such an application is also presented demonstrating the use of the proposed formulation in the modelling of the non-linear elastic and transversely isotropic behaviour of skeletal muscle tissue in compression (the model implementation and fitting procedure have been made freely available). The presented hyperelastic formulations may aid researchers in independently controlling the degree of tension-compression asymmetry from the degree of non-linearity, and in the case of anisotropic materials may assist in determining the role played by, either the ground matrix, or the fibrous reinforcing structures, in generating asymmetry.

description: Most solar panels use patterned glass with a textured back-side. This back-side texture complicates
measurements of transmission and reflected light during characterization of Anti-Reflection (AR) coatings. This paper
describes a method of distinguishing between the front-side and back-side reflections by using a simple handheld
reflectometer and a semi-index-matching stack of water and glass. This water-table method is described in theory and
demonstrated in practice. Glass and AR coatings from different suppliers can be compared on an absolute reflectance
scale, with an error of no more than 0.2%. This result shows that the water-table method is very effective in isolating
the AR performance from confounding factors such as glass-type and hence is an excellent way to accurately compare
AR coatings from different glass suppliers. The method is also useful for durability testing of AR coatings by isolating
the performance of AR coatings from optical effects of degradation on the uncoated glass surfaces.

description: Photoluminescence imaging is often used to image photovoltaic cells and modules under relevant
working conditions. However, it is underrepresented in outdoor imaging methods, owing to the small signal to noise
ratio, and the requirement for steady state environmental conditions. Here we make use of the ‘lock in’ outdoor
imaging technique, and present a modulation sequence for better stability against the influence of environmental
conditions, allowing quantitative analysis of outdoor photoluminescence images. The differential photocurrent
collection efficiency of a silicon heterojunction module is calculated at several working conditions between
maximum power and open circuit conditions.

description: The Goldreich-Schubert-Fricke (GSF) instability is a rotational instability that is thought to contribute to the transfer of angular momentum in differentially rotating stars. It has been included in recent codes of stellar evolution in a diffusion-like approximation, under the assumption that the kinematic viscosity $ν$ is unimportant for the development of the instability. As noted previously by other authors, for most stellar applications this may not be a valid approximation. We discuss this issue in detail, solving the dispersion relation of the perturbed modes for realistic values of $ν$ in the bulk of the radiative zone of the Sun and of three red giant stars at various evolutionary stages. We find that the GSF instability is triggered only in layers of extremely strong shear. In a simple case study, we also investigate the effect of a small deviation from axisymmetry or a small background magnetic field. We find that, like the viscosity, these have a stabilising effect. We conclude that this instability is probably far less efficient in transporting angular momentum than is often assumed, and may not even be present.

description: The complex gut bacterial communities have a major impact on organismal health. However, knowledge of the effects of habitat change on the gut microbiota of wild birds is limited. In this study, we characterized the gut microbiota of two different subspecies of the Silver-eared Mesia (Leiothrix argentauris), the native species (L. rubrogularis) and immigrant species (L. vernayi), , using 16S rRNA gene high-throughput sequencing. These two subspecies live in a trace metal-contaminated area, and L. vernayi was trafficked. They are an excellent system for studying how the gut microbiome of wild animal changes when they move to new habitats. We hypothesized that the immigrant species would develop the same adaptations as the native species in response to habitat changes. The results showed that there were no significant differences in the composition, diversity, or functional metabolism of gut microbiota between native and immigrant species under the combined action of similar influencing factors (The p values of all analyses of variance > 0.05). In addition, the composition and functional metabolism of gut microbiota in two subspecies showed adaptation against trace metal damage. Linear discriminant analysis effect size (LEfSe) analysis revealed that Massilia in the intestinal microbiota of immigrant species was significantly higher than that of native species, suggesting that immigrant species suffered habitat change. Finally, we found that these two subspecies living in the mining area had an extremely high proportion of pathogenic bacteria in their gut microbiota (About 90%), much higher than in other species (About 50%) living in wild environment.

description: To ensure the massive deployment for PERC technology application, light induced degradation (LID)
is one of the most crucial issue. The investigation of P-mono PERC LID is performed from ingot, solar cell, module
to system performance. All cells fabricated with four different ingot sources have high possibility of over 3% LID in
output power, and the oxygen concentration is not correlated with power drop. Only one of the seven cell types
surveyed from the worldwide market has LID less than 3%. The process window for LID is optimized in AUO by
inspecting the external quantum efficiency (EQE) for each cell processing step. In module level, indoor light soaking
test shows smaller LID, while it owns much faster LID recovery rate than outdoor test. Module LID is larger when it
is with resistive load than without mode (at Voc) for both indoor and outdoor test condition. The optimized PERC
module owns less than 2% degradation during 19 month long-term operation in outdoor test system, although it is
applied without any LID regeneration technique in cell or in module level. The module also demonstrates excellent
performance ratio than other types in the field.

description: At the moment, the dominating encapsulation material for PV modules is chemically crosslinked ethylene vinyl-acetate
copolymer (EVA). Besides the time and energy consuming module lamination process, the major drawback of EVA is the
formation of corrosive degradation products like acetic acid during aging. Acetic acid has a great impact on ageing mechanisms
like yellowing of EVA, PID effect, corrosion of metal parts or delamination, and, it is known to accelerate the oxidation
processes in EVA. However, ingress of permeates like oxygen, water or acetic acid, which are assumed to be reaction partners
in degradation processes inside of PV module, is governed by the permeation properties of the polymeric backsheets or
encapsulation materials used. In this paper the main purpose was to correlate permeation properties of backsheets with
formation of acetic acid in the EVA encapsulant layer. Results from previous works showed significant differences in the
permeation behavior of backsheet laminates depending on different layer composition. The lowest permeation rates (up to 100
times lower) were found for laminates containing a polyester (PET) core layer in comparison to co-extruded backsheets based
on polyamides and polyolefines. Therefore, test laminates consisting of EVA encapsulant and backsheet laminates with low
(AAA) and high (APA) barrier layers were prepared and exposed to UV irradiation and temperature. The concentration of
formed and permeated acetic acid was measured via GC/MS method and correlated with different AATR values of the
backsheet laminates. The results were assigned to autocatalytic effect of acetic acid which retained at interfaces of test laminate.
Degradation of EVA in test laminates was investigated after aging via Raman confocal microscopy.

description: Soiling can be a significant loss factor for PV systems, accounting for >5% annual energy loss in locations
without frequent rainfall. Therefore, many manufacturers are investigating the potential benefits of incorporating antisoiling
or self-cleaning properties into PV module coatings. In order to study the potential anti-soiling behavior of various
surface treatments, we have deployed a test station with custom-made PV modules having coatings with both hydrophilic
and hydrophobic properties that may inhibit soiling and/or induce self-cleaning. The soiling of each sample is determined
by comparison to an automatically washed reference cell in the station. We present the motivations for and design of the
station, along with preliminary results regarding the impact of the coatings on soiling.

description: A fast and effective model for the computation of solar energy potential in complex shading
environments is presented. Accurate calculation and identification of solar energy potential profiles is demonstrated
over large areas. Calculation time is exceptionally fast, even on an average specification PC (typically under 1 min
per 1 km2). Problems with commonly used low-resolution sky domes that can lead to irradiance calculation errors of
~5% are identified. Ideal placements are easily visually identified from resultant irradiance/irradiation profile images.
Image processing techniques for spatially distributed optimization problems are described and an example of energy
value optimization is presented by means of individual dwelling demand separation & comparison.

description: A custom built laboratory scale tool that enables line scanning photoluminescence (PL) imaging of full
size photovoltaic modules was demonstrated for the purpose of manufacturing quality control. The tool allows fast onthe-
fly acquisition with exceptional image quality, and can identify series resistance faults without making contact to a
sample. This is due to the use of localised line illumination for photoexcitation, which induces lateral current flow
between the illuminated and non-illuminated regions in a sample. We show that line scanning PL allows a more reliable
differentiation of failure mechanisms than the electroluminescence (EL) imaging systems currently favoured by the
industry.

description: Pulse timing is an important topic in nuclear instrumentation, with far-reaching applications from high energy physics to radiation imaging. While high-speed analog-to-digital converters become more and more developed and accessible, their potential uses and merits in nuclear detector signal processing are still uncertain, partially due to associated timing algorithms which are not fully understood and utilized. In this paper, we propose a novel method based on deep learning for timing analysis of modularized detectors without explicit needs of labelling event data. By taking advantage of the intrinsic time correlations, a label-free loss function with a specially designed regularizer is formed to supervise the training of neural networks towards a meaningful and accurate mapping function. We mathematically demonstrate the existence of the optimal function desired by the method, and give a systematic algorithm for training and calibration of the model. The proposed method is validated on two experimental datasets based on silicon photomultipliers (SiPM) as main transducers. In the toy experiment, the neural network model achieves the single-channel time resolution of 8.8 ps and exhibits robustness against concept drift in the dataset. In the electromagnetic calorimeter experiment, several neural network models (FC, CNN and LSTM) are tested to show their conformance to the underlying physical constraint and to judge their performance against traditional methods. In total, the proposed method works well in either ideal or noisy experimental condition and recovers the time information from waveform samples successfully and precisely.

description: Longterm and standardized performance monitoring of PV plants is essential for future PV deployment. The
value of performance monitoring is widely underestimated and lack of willingness to share operational data make it difficult
to obtain reliable project data. IEA PVPS T13 maintains a performance database with predefined and standardized
performance analysis. In this work, a new approach to assessing and analyzing performance data of large populations of PV
plants is developed, using existing yield data from Feed-in-Tarif (FiT) databases in combination with calculated solar
irradiation values based on measured hourly solar irradiation data.
This approach is applied exemplary to the Swiss PV market, producing 1’170 PV projects for performance analysis and
confirming the potential to monitor large amounts of PV projects in all countries with FiT. The number of entries in the IEA
PVPS performance database over all countries can be doubled with the assessed Swiss PV projects of this work. First
findings confirm average PR of 0.75, differences in performance between small and large PV plants in the range of 2…5%
and around 6.8% higher average specific yield than assumed in FiT models.
