description: Majorana neutrinos naturally lead to a Lepton Number Violation (LNV). A superposition of Majorana states can mimic Dirac-type neutrinos, leading to its conservation (LNC). We demonstrate on the example of specific observables related to high and low energy processes how a strength of LNV correlates with neutrino parameters such as CP-phases, flavor mixings, mass ratios. We stress the coaction between low and high energy studies for putting phenomenological models to a quantitative test. Secondly, we conclude that in order to fully study the role of heavy neutrinos in search for New Physics (NP) signals, a departure from trivial scenarios assuming degeneracy in mass and no flavor mixing or CP-phases becomes necessary for a proper physical analysis.

description: In this paper, the boron-oxygen complex related light induced degrade and regeneration process is
studied on industrial solar cell. Injection with simultaneously annealing is a practical way for regeneration of LID. We
have applied injection on both solar cells and modules. Both forward current and light illumination works as injection
sources. We use cell stacks for current injection. The process cost minutes for a cell stack. When using light as
injection source, a proper lamp source and temperature is favor for the LIR result. The process time for the light
injection process is about 30 seconds. The best LIR result is smaller than 0.5% for mono PERC cell and the cell
efficiency seems to be stable during the substantial 48 hours stability test.

description: Thermal transport of nanocrystalline Si is of great importance for the application of thermoelectrics. A better understanding of the modal thermal conductivity of nanocrystalline Si will be expected to benefit the efficiency of thermoelectrics. In this work, the variance reduced Monte Carlo simulation with full band of phonon dispersion is applied to study the modal thermal conductivity of nanocrystalline Si. Importantly, the phonon modal transmissions across the grain boundaries which are modeled by the amorphous Si interface are calculated by the mode-resolved atomistic Greens function method. The predicted ratios of thermal conductivity of nanocrystalline Si to that of bulk Si agree well with that of the experimental measurements in a wide range of grain size. The thermal conductivity of nanocrystalline Si is decreased from 54 percent to 3 percent and the contribution of phonons with mean free path larger than the grain size increases from 30 percent to 96 percnet as the grain size decreases from 550 nm to 10 nm. This work demonstrates that the full band Monte Carlo simulation using phonon modal transmission by the mode-resolved atomistic Greens function method can capture the phonon transport picture in complex nanostructures, and therefore can provide guidance for designing high performance Si based thermoelectrics.

description: We report a discovery of a 1.3 Mpc diffuse radio source with extremely steep spectrum fading radio structures in the vicinity of the Abell 449 cluster of galaxies. Its extended diffuse lobes are bright only at low radio frequencies and their synchrotron age is about 160 Myr. The parent galaxy of the extended relic structure, which is the dominant galaxy within the cluster, is starting a new jet activity. There are three weak X-rays sources in the vicinity of the cluster as found in the ROSAT survey, however it is not known if they are connected with this cluster of galaxies. Just a few radio galaxy relics are currently known in the literature, as finding them requires sensitive and high angular resolution low-frequency radio observations. Objects of this kind, which also are starting a new jet activity, are important for understanding the life cycle and evolution of active galactic nuclei. A new 613 MHz map as well as the archival radio data pertaining to this object are presented and analyzed.

description: N-type solar cells with an ion-implanted selective back surface field (SBSF) were produced by mass
production with 156mm×156mm CZ wafers. Cells efficiency is 20.4% with in-situ SiO passivation. The SBSF used
patterned ion-implant technology. 3D modeling and simulation was done with Quokka. Modeling indicates that after
optimization of the SBSF, the cell efficiency gains 0.2% absolute compared with rear totally homogeneous doped
cells after process optimization. Modeling also demonstrates the SBSF cells reach the best efficiency at a wafer
resistivity around 0.5~1 Ω∙cm depend on wafer lifetime. Cells with efficiency more than 21% are expected by
optimizing field area sheet resistance and using wafers with 0.5~1 Ω∙cm resistivity and chemical passivation.

description: Fermions become polarized in a vortical fluid due to spin-vorticity coupling. The spin polarization density is proportional to the local fluid vorticity at the next-to-leading order of a gradient expansion in a quantum kinetic theory. Spin correlations of two $Λ$-hyperons can therefore reveal the vortical structure of the dense matter in high-energy heavy-ion collisions. We employ a (3+1)D viscous hydrodynamic model with event-by-event fluctuating initial conditions from A MultiPhase Transport (AMPT) model to calculate the vorticity distributions and $Λ$ spin correlations. The azimuthal correlation of the transverse spin is shown to have a cosine form plus an offset due to a circular structure of the transverse vorticity around the beam direction and global spin polarization. The longitudinal spin correlation shows a structure of vortex-pairing in the transverse plane due to the convective flow of hot spots in the radial direction. The dependence on colliding energy, rapidity, centrality and sensitivity to the shear viscosity are also investigated.

description: The advances in contact formation of screen printed Ag pastes and the related progress in emitter
profile tailoring has been a key driver for recent efficiency improvements. This paper summarizes the current status
of phosphorus-diffused emitters for p-type silicon solar cells and discusses two technological options for advanced
tube furnace POCl3-diffusion processes: diluted source and in-situ post oxidation. Lower surface doping
concentration levels are identified as key parameter for further reducing carrier recombination in the emitter. Using
analytical modelling, we estimate potential efficiency improvements of 0.3%abs for PERC type solar cells from
reducing the surface concentration from 2x1020 cm-3 down to 1019 cm-3. We also address the increasing importance of
recombination at the metal contacts and investigate the role of the diffusion profile and sheet resistance by analytical
modelling. If metal contact recombination is supressed by a selective emitter and/or advanced low recombination
metallization pastes, a potential efficiency gain of 0.5%abs is predicted.

description: Low pressure diffusion in tube furnaces was employed to generate boron- and phosphorous doping
profiles which are suitable for emitters of advanced n- and p-type silicon solar cells. The dopant sources were POCl3
and BBr3 respectively. It was shown that for both elements surface concentrations and junction depths can be varied
almost independently over the range of interest here. Good uniformities of sheet resistances could be demonstrated
for load sizes of 1000 wafers per run in back to back loading. The low pressure boron diffusion was successfully
applied to a bifacial n-PERT solar cell. In these cells the BSG is left on the front side emitter and together with a
PECVD SiNx forms passivation as well as antireflective coating. Excellent electrical and optical performance of this
stack was demonstrated. Best cell efficiencies of 20.45% were achieved.

description: We experimentally explore pressure-driven flow of water and n-hexane across nanoporous silica (Vycor glass monoliths with 7 or 10 nm pore diameters, respectively) as a function of temperature and surface functionalization (native and silanized glass surfaces). Hydraulic flow rates are measured by applying hydrostatic pressures via inert gases (argon and helium, pressurized up to 70 bar) on the upstream side in a capacitor-based membrane permeability setup. For the native, hydrophilic silica walls, the measured hydraulic permeabilities can be quantitatively accounted for by bulk fluidity provided we assume a sticking boundary layer, i.e. a negative velocity slip length of molecular dimensions. The thickness of this boundary layer is discussed with regard to previous capillarity-driven flow experiments (spontaneous imbibition) and with regard to velocity slippage at the pore walls resulting from dissolved gas. Water flow across the silanized, hydrophobic nanopores is blocked up to a hydrostatic pressure of at least 70 bar. The absence of a sticking boundary layer quantitatively accounts for an enhanced n-hexane permeability in the hydrophobic compared to the hydrophilic nanopores.

description: 31st European Photovoltaic Solar Energy Conference and Exhibition; 440-443
description: We demonstrate that complex luminescence spectra from silicon wafers can be accurately modelled
using a simple expression for the individual phonon-related components. By using combinations of various phonon
emission and absorption events, it is possible to build up the entire luminescence spectra, which we demonstrate for
temperatures between 78 to 300 K. At room temperature, the dominant components of the spectra are caused by
emission and absorption of momentum-conserving transverse optical and transverse acoustic phonons. Secondary
phonon replicas also involve the emission of non-momentum-conserving inter-valley phonons. The model correctly
reproduces the changes in sharpness of the measured spectra as a function of temperature, as well as correctly
accounting for the relative change in impact of phonon emission and absorption related luminescence. At low
temperatures, additional peaks caused by recombination through neutral dopant atoms are also evident, and can be
modelled using the same approach. The model may be useful for understanding luminescence spectra from silicon
wafers and solar cells.

The method gives a more direct approach to the generalization by Dogra of the quadratic Chabauty method to arbitrary number fields.

description: Selective n++/n+ doping through one-step thermal diffusion and its application as BSF for N-type frontjunction
solar cells have been presented. A silicon wafer is pre-treated with hydrofluoric acid and a laser process in
order to engineer the wettability of the surface. The dopant source of phosphoric acid is allowed to be localized to the
hydrophilic region while the hydrophobic region is left bare. One-step diffusion hence creates selectively heavy
doping where the dopant source is localized. The doping pattern and concentration are controllable by tuning the laser
scanning and diffusion. An effective back-surface-field of n-type front-junction solar cells is formed. The fabricated
cells show an absolute Voc gain of 11 mV. The resulting absolute efficiency gain is 0.4 % compared to the reference
cells with a homogeneous BSF. The process simplicity and the efficiency gain suggest a promising route for mass
production.

description: Big data has been emerging as a new approach in utilizing large datasets to optimize complex system operations. Big data is fueled with Internet-of-Things (IoT) services that generate immense sensory data from numerous sensors and devices. While most current research focus of big data is on machine learning and resource management design, the economic modeling and analysis have been largely overlooked. This paper thus investigates the big data market model and optimal pricing scheme. We first study the utility of data from the data science perspective, i.e., using the machine learning methods. We then introduce the market model and develop an optimal pricing scheme afterward. The case study shows clearly the suitability of the proposed data utility functions. The numerical examples demonstrate that big data and IoT service provider can achieve the maximum profit through the proposed market model.

description: Automatic optimization of spoken dialog management policies that are robust to environmental noise has long been the goal for both academia and industry. Approaches based on reinforcement learning have been proved to be effective. However, the numerical representation of dialog policy is human-incomprehensible and difficult for dialog system designers to verify or modify, which limits its practical application. In this paper we propose a novel framework for optimizing dialog policies specified in domain language using genetic algorithm. The human-interpretable representation of policy makes the method suitable for practical employment. We present learning algorithms using user simulation and real human-machine dialogs respectively.Empirical experimental results are given to show the effectiveness of the proposed approach.

description: Diese Masterarbeit befasst sich mit dem Phänomen der «Resilienz». Genauer gesagt mit der Frage, was es ausmacht, dass gewisse Menschen im Leben an Herausforderungen scheitern und andere ihr Leben trotz schwierigen Umständen gut meistern. Es wird der Frage nachgegangen, wie die Resilienz auf der Grundlage der sechs Resilienzfaktoren im Unterricht der Primarschule gestärkt werden kann. Mittels einer Literaturanalyse des aktuellen Forschungsstandes und eines Experteninterviews wurden Teilbereiche definiert, welche für eine Förderung der Resilienz eminent sind. Es zeigte sich, dass die Resilienzfaktoren Wechselwirkungen eingehen und nicht einzeln betrachtet werden sollten. Zur Bearbeitung der Forschungsfrage wurden drei Prinzipien als Leitgedanken und Bedingungen identifiziert. Aus den Prinzipien wurden sechs Fördermethoden abgeleitet, mit denen möglichst viele Resilienzfaktoren vereint gestärkt werden können.

description: ND280 is a near detector of the T2K experiment which is located in the J-PARC accelerator complex in Japan. After a decade of fruitful data-taking, ND280 is scheduled for upgrade. The time-of-flight (ToF) detector, which is described in this article, is one of three new detectors that will be installed in the basket of ND280. The ToF detector has a modular structure. Each module represents an array of 20 plastic scintillator bars which are stacked in a plane of 2.4 x 2.2 m2 area. Six modules of similar construction will be assembled in a cube, thus providing an almost 4pi enclosure for an active neutrino target and two TPCs. The light emitted by scintillator is absorbed by arrays of large-area silicon photo-multipliers (SiPMs) which are attached to both ends of every bar. The readout of SiPMs, shaping and analog sum of individual SiPM signals within the array are performed by a discrete circuit amplifier. An average time resolution of about 0.14 ns is achieved for a single bar when measured with cosmic muons. The detector will be installed in the basket of ND280, where it will be used to veto particle originating outside the neutrino target, improve the particle identification and provide a cosmic trigger for calibration of detectors which are enclosed inside it.

boundary conditions and performance. Using the integrated process which is fully compatible with bonded foils, cells
were fabricated on a freestanding, non-textured wafer. An efficiency of 18.0% was achieved, the main limitations being
the absence of surface texturing and a non-optimized amorphous silicon emitter.

title: Structural Integrity Assessment of Metallic Components Based on Representative Specimens

description: Safety relevant components, for which a failure in service could have catastrophic consequences, are usually designed for extremely low probability of failure and they are subjected to stringent part qualification procedures according to guidelines set by regulatory agencies. Manufacturers are often pushed to perform tests on full scale or scaled components to ensure the structural integrity under defined loading conditions, which are usually more severe than those expected in-service. This is usually related to a huge experimental and financial effort. Therefore, companies try to develop new strategies such as digital twins, which allow to reduce costs massively, without compromising safety. This work aims at introducing a new structural integrity assessment procedure, the main idea of which is to replace, or at least reduce, the experimental testing on components by designing specimens representative of the component, having the major benefit to be tested on conventional lab testing machines under quasi-static conditions. The effectiveness of the methodology is demonstrated on an industrial case study, namely the structural integrity of a Ni base superalloy disk used in gas turbine aero-engines at overspeed conditions. Firstly, the most stressed sites in the component under combined thermo-mechanical loads have been identified by numerical analyses. The maximum permissible defect defined by regulatory agencies has been introduced at the critical locations to calculate the crack-tip parameters to be used for the representative specimen design. Fracture mechanics specimens have been designed iteratively by numerical simulations to match the stress state including the constraint conditions and the crack-tip loading parameters determined on the component. An extensive experimental campaign has been conducted on representative specimens to determine the failure modes (ductile tearing or plastic collapse). The information about the stable crack extension have been determined post-mortem by fractographic analyses and used in conjunction with dedicated numerical analyses to determine the crack growth resistance curves (R-curves). These have been used in the frame of an analytical flaw assessment procedure based on the CDF philosophy according to the European SINTAP procedure, in order to predict the failure modes and the corresponding critical loads. The results are in good agreement with the experimental tests and show the potential of the presented methodology to predict failures in metallic components.

description: Internal mechanism leading to the emergence of the widely occurring 1/f noise still remains an open issue. In this paper we investigate the distinction between internal time of the system and the physical time as a source of 1/f noise. After demonstrating the appearance of 1/f noise in the earlier proposed point process model, we generalize it starting from a stochastic differential equation which describes a Brownian-like motion in the internal (operational) time. We consider this equation together with an additional equation relating the internal time to the external (physical) time. We show that the relation between the internal time and the physical time that depends on the intensity of the signal can lead to 1/f noise in a wide interval of frequencies. The present model can be useful for the explanation of the appearance of 1/f noise in different systems.

description: Viele Lehrpersonen nehmen an Gesprächen mit albanischen Eltern wahr, dass diese sich kaum oder gar nicht mit dem Schweizer Bildungssystem auskennen. Somit ist es für albanische Eltern schwierig, ihre Jugendlichen beim Berufswahlprozess optimal zu begleiten. Für die Lehrpersonen stellt diese Situation eine Herausforderung dar und verlangt u.a. eine gute Vorbereitung der Elterngespräche und eine enge Zusammenarbeit mit den Eltern beim Thema Übergang Schule-Beruf. In der vorliegenden Arbeit wird die Frage vertieft, wie die Kommunikation zwischen albanischen Eltern und der Schule verbessert werden kann, damit die Jugendlichen mit Förderbedarf bei der Berufswahl optimal unterstützt werden können. Als Produkt dieser Entwicklungsarbeit wird ein Leitfaden für Lehrpersonen erstellt, welcher ihnen als Vorbereitung für zielführende Gespräche mit albanischen Eltern dient und die Herausforderung minimieren soll. Anhand eines qualitativen Fragebogens wird der Leitfaden von vier Lehrpersonen evaluiert und anschliessend optimiert. Die Ergebnisse der Evaluation zeigen auf, dass der Leitfaden eine bewusste Auseinandersetzung mit der eigenen Planung eines Elterngesprächs ermöglicht. Weiter ist es entscheidend, dass sich die Lehrpersonen mit der albanischen Kultur auseinandersetzen und die Eltern über das Schweizer Bildungssystem informieren, damit diese die albanischen Jugendlichen mit Förderbedarf im Berufswahlprozess optimal unterstützen können.

description: We discuss an idea whether spherical blast waves can amplify by a non-local resonant hydrodynamic mechanism inhomogeneities formed by turbulence or phase segregation in the interstellar medium. We consider the problem of a blast-wave-turbulence interaction in the Linear Interaction Approximation. Mathematically, this is an eigenvalue problem for finding the structure and amplitude of eigenfunctions describing the response of the shock-wave flow to forced oscillations by external perturbations in the ambient interstellar medium. Linear analysis shows that the blast wave can amplify density and vorticity perturbations for a wide range of length scales with amplification coefficients of up to 20, with amplification the greater, the larger the length. There also exist resonant harmonics for which the gain becomes formally infinite in the linear approximation. Their orbital wavenumbers are within the range of macro- ($l \sim 1$), meso- ($l \sim 20$) and microscopic ($l > 200$) scales. Since the resonance width is narrow: typically, $Δl <1$, resonance should select and amplify discrete isolated harmonics. We speculate as to a possible explanation of an observed regular filamentary structure of regular-shaped round supernova remnants such as SNR 1572, 1006 or 0509-67.5. Resonant mesoscales found ($l \approx 18 $) are surprisingly close to the observed scales ($l \approx 15$) of ripples in the shell's surface of SNR 0509-67.5.

Silicon Solar Cell Improvements

description: 31st European Photovoltaic Solar Energy Conference and Exhibition; 410-413
description: We report on the progress of imec’s n-PERT (Passivated Emitter, Rear Totally diffused) rear junction
solar cells. Selective laser doping (LD) has been introduced in the flow replacing the laser ablation step (LA) to
improve the front surface field and reduce the recombination current in the contact area. Simplifications have been
introduced towards a more industrial annealing sequence, by replacing all expensive forming gas steps with a belt
furnace annealing (BFA). The passivation quality of this process has been evaluated on test structures with doped
surfaces. Applying this process to our rear junction design, 22.5% efficient cells have been measured on 6”-
commercial Czochralski (Cz)-Si. This result has been independently confirmed by ISE CalLab. Smart Wire
Connection Technology (SWCT) has been applied to our cells showing a power output over 5 W in a 1-cell laminate,
which could be translated into a 60-cell module power over 300 W.
Keisler's Theorem and Cardinal Invariants

description: We consider several variants of Keisler's isomorphism theorem. We separate these variants by showing implications between them and cardinal invariants hypotheses. We characterize saturation hypotheses that are stronger than Keisler's theorem with respect to models of size $\aleph_1$ and $\aleph_0$ by $\mathrm{CH}$ and $\operatorname{cov}(\mathsf{meager}) = \mathfrak{c} \land 2^{<\mathfrak{c}} = \mathfrak{c}$ respectively. We prove that Keisler's theorem for models of size $\aleph_1$ and $\aleph_0$ implies $\mathfrak{b} = \aleph_1$ and $\operatorname{cov}(\mathsf{null}) \le \mathfrak{d}$ respectively. As a consequence, Keisler's theorem for models of size $\aleph_0$ fails in the random model. We also show that for Keisler's theorem for models of size $\aleph_1$ to hold it is not necessary that $\operatorname{cov}(\mathsf{meager})$ equals $\mathfrak{c}$.

description: Low-mass (sub-eV) spin-0 dark matter particles, which form a coherently oscillating classical field $ϕ= ϕ_0 \cos(m_ϕt)$, can induce oscillating variations in the fundamental constants through their interactions with the Standard Model sector. We calculate the effects of such possible interactions, which may include the linear interaction of $ϕ$ with the Higgs boson, on atomic and molecular transitions. Using recent atomic clock spectroscopy measurements, we derive new limits on the linear interaction of $ϕ$ with the Higgs boson, as well as its quadratic interactions with the photon and light quarks. For the linear interaction of $ϕ$ with the Higgs boson, our derived limits improve on existing constraints by up to $2-3$ orders of magnitude.

description: In a previous paper, we showed that a class of time travel paradoxes which cannot be resolved using Novikov's self-consistency conjecture can be resolved by assuming the existence of multiple histories or parallel timelines. However, our proof was obtained using a simplistic toy model, which was formulated using contrived laws of physics. In the present paper we define and analyze a new model of time travel paradoxes, which is more compatible with known physics. This model consists of a traversable Morris-Thorne wormhole time machine in 3+1 spacetime dimensions. We define the spacetime topology and geometry of the model, calculate the geodesics of objects passing through the time machine, and prove that this model inevitably leads to paradoxes which cannot be resolved using Novikov's conjecture, but can be resolved using multiple histories. An open-source simulation of our new model using Mathematica is available for download on GitHub. We also provide additional arguments against the Novikov self-consistency conjecture by considering two new paradoxes, the switch paradox and the password paradox, for which assuming self-consistency inevitably leads to counter-intuitive consequences. Our new results provide more substantial support to our claim that if time travel is possible, then multiple histories or parallel timelines must also be possible.

description: We present a new automated method to identify instrumental features masquerading as small, long period planets in the \kepler\ planet candidate catalog. These systematics, mistakenly identified as planet transits, can have a strong impact on occurrence rate calculations because they cluster in a region of parameter space where Kepler's sensitivity to planets is poor. We compare individual transit-like events to a variety of models of real transits and systematic events, and use a Bayesian Information Criterion to evaluate the likelihood that each event is real. We describe our technique and test its performance on simulated data. Results from this technique are incorporated in the \kepler\ Q1-17 DR24 planet candidate catalog of \citet{Coughlin15}.

description: According to Ayurveda, a healthy diet can prevent a lot of health issues. Food is crucial as a source of nutrition and also has significant medicinal value. Nutritional deficiencies, often known as undernutrition, are caused by insufficient dietary consumption. Karshya (undernutrition) is a disease described in Ayurveda as ‘Ashtanindaniya purush’ (Eight undesirable persons acc to ayurveda). Karshya is a condition or disease in which the body of a person becomes emaciated, having less quantity of rasa dhatu further causing a status of mamsahinata or manskshaya. The aim of this study is a comparative evaluation of the Bruhaniya (‘bulk promoting’) effect of Kushmanda granules and Ashwagandha granules in Karshya. The objective is to assess the effect of Kushmanda granules on body weight, BMI, arm and waist circumference, and skin fold thickness in patients of Karshya and to compare the effect of Kushmanda granules and Ashwagandha granules.
