description: This master's thesis research introduces the topic of the outdoor learning in forest schools in Finland. Outdoor pre-schools offer courses in a woodland environment whatever the weather to 6 years old preschoolers. This paper aims to study children development through the effects on nature experiences and the nature pedagogy. We speculate that both environmental aspects may have a positive impact on the basics learning and the emotional capital, including social skills. The research encompasses two investigations. First, a case study carried out with an outdoor preschooler group in a Finnish forest school. Then, interviews carried out with outside teachers and parents. Results highlight that the multi-sensorial learning and inner motivation put the children into an active learning process. Besides, social skills are the key priority at the forest school. Kids develop social skills in a context of social peace (almost no conflicts in the group) which help them to regulate their emotions.
 Children develop empathy thanks to the use of cooperative methods and the connection to living systems. This encourages to raise an environmental and social awareness. Ce mémoire s’intéresse à l’apprentissage en plein air dans les écoles de la forêt finlandaises, qui font la classe dehors par tous les temps, à des enfants âgés de 6 ans. Notre objectif est d’étudier l’effet des expériences de nature et de la pédagogie par la nature sur le développement de l’enfant.
 Les questions de recherche interrogent l’environnement de l’apprentissage : la pédagogie et la connexion à la nature permettraient d’une part, un accès facilité à l’apprentissage des fondamentaux scolaires et d’autre part, le développement du capital émotionnel. Le protocole de recherche comprend une enquête observatoire bâtie sur une étude de cas réalisée avec les enfants d’une école de la forêt finlandaise et une enquête principale basée sur des entretiens semi-directifs auprès d’enseignants et de parents. Les résultats de l’analyse thématique démontrent que l’aspect multi-sensoriel et la motivation endogène générée par le biais de la pédagogie par la nature permettent l’engagement de l’enfant dans un processus d’apprentissage actif. Objectif prioritaire, l’acquisition de compétences sociales se développe dans un contexte de paix sociale (quasi-absence de conflits) permettant le développement de la maîtrise de soi (régulation des émotions). Les méthodes coopératives et la connexion au monde vivant favorisent l’empathie et l’émergence d’une conscience environnementale et sociale.

description: We consider the implications of the recent results of SAGE and GALLEX experiments for the solution of the solar neutrino problem in the framework of the resonant neutrino spin-flavor precession scenario. It is shown that this scenario is consistent with all the existing solar neutrino data including the gallium results. The quality of the fit of the data depends crucially on the magnetic field profile used which makes it possible to get information about the magnetic field in the solar interior. In particular, the magnetic field in the core of the sun must not be too strong ($<3 \times 10^6$ G). The detection rate in the gallium detectors turns out to be especially sensitive to the magnitude of $Δm^2$. Predictions for forthcoming solar-neutrino experiments are made.

Ligand-Mediated Stabilization of Low Temperature Metal Eutectics and Their Use in Composite Systems

Publisher: name: Carnegie Mellon University
Year: 2017
Subjects: subject: 91299 Materials Engineering not elsewhere classified

description: objective of this thesis is to contribute to the understanding of the behavior of the liquid metal eutectic gallium/indium (EGaIn) in composite systems and provide a platform for the development of functional hybrid nanocomposites. Contributions are regarding (i) the investigation of the electromechanical coupling performance of EGaIn as electrodes in a soft electrostatic transducer and (ii) the effectiveness of organic surfactants to stabilize EGaIn nanoparticles in organic solvents. For the first portion, a completely soft dielectric elastomer actuator (DEA) using EGaIn electrodes was fabricated and evaluated. Experimental actuation of the DEA showed high agreement with a generalized NeoHookean constitutive law, assuming uniaxial pre-stretch and considering the device saddle deformation. The expected conductive behavior of the liquid alloy was confirmed, and further efforts have focused on the development and stabilization of EGaIn nanodroplets, which do not exhibit the problems associated with larger pools of EGaIn (such as leakage) and can be applied to soft multifunctional materials. A computational procedure was developed for calculating suspended EGaIn nanoparticle mass in order to determine reaction yields using applied Mie theory and optical characterization techniques (dynamic light scattering and UV/Vis spectrophotometry). This method calculated total mass to within 20% when applied to a known system. A systematic study evaluating particle yield as a function of aliphatic surfactant composition and concentration (and solvent type) revealed a pronounced dependence of nanodroplet formation on the solvent type as well as surfactant structure. Ethanol (EtOH) was found to be the most effective solvent for the formation and stabilization of EGaIn nanodroplets, in which only thiol-based surfactants were found to improve nanodroplet yield. Results suggest a stabilization mechanism other than the expected self-assembled monolayer (SAM) formation. The research has been extended to alternative (e.g. plant based) surfactant systems.
Vortex condensation in a model of random $ϕ^{4}$-graphs

description: We consider a soluble model of large $ϕ^{4}$-graphs randomly embedded in one compactified dimension; namely the large-order behaviour of finite-temperature perturbation theory for the partition function of the anharmonic oscillator. We solve the model using semi-classical methods and demonstrate the existence of a critical temperature at which the system undergoes a second-order phase transition from $D=1$ to $D=0$ behaviour. Non-trivial windings of the closed loops in a graph around the compactified time direction are interpreted as vortices. The critical point has a natural interpretation as the temperature at which these vortices condense and disorder the system. We show that the vortex density increases rapidly in the critical region indicating the breakdown of the dilute vortex gas approximation at this point. We discuss the relation of this phenomenon to the Berezinskii-Kosterlitz-Thouless transition in the $D=1$ matrix model formulated on a circle.

description: Visualizing regional-scale landslides is essential to conveying the threat of natural hazards to stakeholders and policymakers. Traditional visualization techniques are restricted to post-processing a limited subset of simulation data and are not scalable to rendering regional-scale models. In situ visualization is a technique of rendering simulation data in real-time, i.e., rendering visuals in tandem while the simulation is running. This study develops a scalable N:M interface architecture to visualize regional-scale landslides. We demonstrate the scalability of the architecture by simulating the long runout of the 2014 Oso landslide using the Material Point Method coupled with the Galaxy ray tracing engine rendering 4.2 million material points as spheres. In situ visualization has an amortized runtime increase of 2% compared to non-visualized simulations. The developed approach can achieve in situ visualization of regional-scale landslides with minimal impact on the simulation process.

Many-body localization transition with power-law interactions: Statistics of eigenstates

description: We study spectral and wavefunction statistics for many-body localization transition in systems with long-range interactions decaying as $1/r^α$ with an exponent $α$ satisfying $ d \le α\le 2d$, where $d$ is the spatial dimensionality. We refine earlier arguments and show that the system undergoes a localization transition as a function of the rescaled disorder $W^* = W / L^{2d-α} \ln L$, where $W$ is the disorder strength and $L$ the system size. This transition has much in common with that on random regular graphs. We further perform a detailed analysis of the inverse participation ratio (IPR) of many-body wavefunctions, exploring how ergodic behavior in the delocalized phase switches to fractal one at the critical point and on the localized side of the transition. Our analytical results for the scaling of the critical disorder $W$ with the system size $L$ and for the scaling of IPR in the delocalized and localized phases are supported and corroborated by exact diagonalization of spin chains.
Reflections: An Investigation into Mothers’ Experiences of Having an Adult Offspring with Mild Learning Disabilities

description: This is a qualitative study exploring the personal accounts of mothers of adult offspring with a diagnosis of mild learning disabilities (LD). Evidence has shown that the experiences of such mothers is under-represented in counselling and psychotherapy research. This study aims to address the gap. Eight participants were purposively selected for the project and were then interviewed using semi-structured interviews. The interviews were transcribed verbatim and analysed using Interpretative Phenomenological Analysis (IPA). The results of the analysis represent my interpretation of participants’ lived experiences of being mothers of adult offspring with a diagnosis of mild LD. The three superordinate themes which were generated in the participants’ personal accounts relating to the mothers’ experience are as follows: a) ‘Getting on with it’: unallowable emotions in living with a disabled offspring, b) Adult disability as invisible: falling off a cliff after the end of childhood, c) Glimmers of adulthood: negotiating transitions without a roadmap. Each theme consisted of two to three subthemes. Firstly, the research findings indicate that mothers of adult offspring with a diagnosis of mild LD often avoid negative emotions, which may prove unbearable in the present. Secondly, as the offspring reach adulthood and formal support significantly decreases, both the offspring and the mothers become ‘invisible’ to the services. Subsequently the lack of a future plan becomes apparent for both the adults with a diagnosis of LD and the mothers. This is in line with Turner’ theory of liminality (1969) which illustrates that despite the fact a person with LD becomes an adult, they often do not conform to a normative pathway and remain in a liminal state. Nevertheless, despite all the difficulties, mothers remain positive and try to focus on any capacity and the glimmers of adulthood displayed by their offspring with LD. The study highlights the need for improvement of health and social services for mothers of adult offspring with LD. Recommendations for future research are outlined and the role of professionals in future clinical practice is explored.

description: We study the exceptional point (EP) phenomena in a photonic medium with a complex time-periodic permiitivity, i.e., $ε(t)=ε_o+ε_r*sin(Ωt+ϕ)$. We formulate the Maxwell's equations in a form of first-order non-Hermitian Floquet Hamiltonian matrix and solve it analytically for the Floquet band structures. In the case when $ε_r$ is real, to the first order in $ε_r$, the band structures show a phase transition from an exact phase with real quasienergies to a broken phase with complex quasienergies inside a region of wave vector space, the so-called k-gap. We show that the two EPs at the upper and lower edges of the k-gap have opposite chiralities in the stroboscopic sense. Thus, by picking up the mode with a positive imaginary quasienergy, the wave propagation inside the k-gap can grow exponentially. In three dimensions, such pairs of EPs span two concentric spherical surfaces in the $\vec{k}$ space and repeat themselves periodically in the quasienergy space with Omega as the period. However, in the case when $ε_r$ is pure imaginary, the k-gap disappears and gaps in the quasienergy space are opened. Our analytical results agree well with the finite difference time domain (FDTD) simulations. To the second order in $ε_r$, additional EP pairs are found for both the cases of real and imaginary $ε_r$.

Quantum computing algorithms for the quantum simulation of these systems have recently witnessed remarkable growth, notwithstanding the limitations of existing quantum hardware, especially as a tool for electronic structure computations in molecules. In this review, we provide a self-contained introduction to emerging algorithms for the simulation of Hamiltonian dynamics and eigenstates, with emphasis on their applications to the electronic structure in molecular systems. Theoretical foundations and implementation details of the method are discussed, and their strengths, limitations, and recent advances are presented.

Lifelong Robotic Object Perception

Publisher: name: Carnegie Mellon University
Year: 2012
Subjects: subject: 80101 Adaptive Agents and Intelligent Robotics
subject: FOS: Computer and information sciences

description: In this thesis, we study the topic of Lifelong Robotic Object Perception. We propose, as a long-term goal, a framework to recognize known objects and to discover unknown objects in the environment as the robot operates, for as long as the robot operates. We build the foundations for Lifelong Robotic Object Perception by focusing our study on the two critical components of this framework: 1) how to recognize and register known objects for robotic manipulation, and 2) how to automatically discover novel objects in the environment so that we can recognize them in the future. Our work on Object Recognition and Pose Estimation addresses two main challenges in computer vision for robotics: robust performance in complex scenes, and low latency for real-time operation. We present MOPED, a framework for Multiple Object Pose Estimation and Detection that integrates single-image and multi-image object recognition and pose estimation in one optimized, robust, and scalable framework. We extend MOPED to leverage RGBD images using an adaptive image-depth fusion model based on maximum likelihood estimates. We incorporate this model to each stage of MOPED to achieve object recognition robust to imperfect depth data. In Robotic Object Discovery, we address the challenges of scalability and robustness for long-term operation. As a first step towards Lifelong Robotic Object Perception, we aim to automatically process the raw video stream of an entire workday of a robotic agent to discover novel objects. The key to achieve this goal is to incorporate non-visual information| robotic metadata|in the discovery process. We encode the natural constraints and nonvisual sensory information in service robotics to make long-term object discovery feasible. We introduce an optimized implementation, HerbDisc, that processes a video stream of 6 h 20 min of challenging human environments in under 19 min and discovers 206 novel objects. We tailor our solutions to the sensing capabilities and requirements in service robotics, with the goal of enabling our service robot, HERB, to operate autonomously in human environments.

description: It is well known that the spontaneous breaking of discrete symmetries may lead to conflict with big-bang cosmology. This is due to formation of domain walls which give unacceptable contribution to the energy density of the universe. On the other hand it is expected that gravity breaks global symmetries explicitly. In this work we propose that this could provide a natural solution to the domain-wall problem.

Life Cycle Cost and Environmental Implications of U.S. Electric Vehicle and Charging Infrastructure Scenarios
Creators: name: Traut, Elizabeth
Publisher: name: Carnegie Mellon University

Subjects: subject: Mechanical Engineering
subject: FOS: Mechanical engineering

description: This thesis examines life cycle cost, greenhouse gas (GHG) emissions, petroleum use, and policy implications of scenarios for electrified vehicles and charging infrastructure in the U.S., addressing several questions: What mix of vehicles minimizes life cycle cost? GHG emissions? What are the implications of workplace charging in addition to home charging? How much current and potential U.S. residential charging exists? What are the costs and GHG emissions of fast-charging and battery swapping service stations? How sensitive are these results to uncertain parameters? What factors are most critical? and What are the policy implications? Results indicate that without sufficiently clean electricity, plug-in vehicles (PEVs) with home and workplace charging do not offer substantial reductions in GHG emissions compared to hybrid electric vehicles (HEVs). Benefits improve with low-emission electricity generation. High gas prices ($6/gal) cause PEVs to appear in minimum cost solutions and combined with low vehicle and battery costs (DOE 2030 targets) cause PEVs to dominate. Currently 79% of households but only 56% of vehicles have home parking where charging could be installed. Excluding renters, who face additional barriers, less than half of U.S. vehicles have reliable access to off-street parking where charging could be installed. This places a major limit on potential penetration of PEVs for the foreseeable future. Battery swapping stations cost 40% more per vehicle served than fast charging stations without the cost of waiting time during service, but 50% less when it is included. Battery swapping’s cost advantage requires vehicle and battery standardization. Several policy implications are identified. Gas prices and vehicle and battery prices are identified as price levers to encourage adoption and reduce petroleum consumption, but clean electricity is also needed for GHG emissions reductions. Lack of residential charging could curb adoption and needs attention since parking infrastructure turns over more slowly than the vehicle fleet. With clean electricity, dedicated workplace charging further reduces GHGs. Battery electric vehicle (BEV) adoption is restricted by limited range. Rapid BEV refueling options include fast charging, which incurs costly waiting times during service, or battery swapping, which is faster and potentially less costly but requires vehicle and battery standardization.

description: We study the antiferromagnetic 3-state Potts model on general (periodic) plane quadrangulations $Γ$. Any quadrangulation can be built from a dual pair $(G,G^*)$. Based on the duality properties of $G$, we propose a new criterion to predict the phase diagram of this model. If $Γ$ is of self-dual type (i.e., if $G$ is isomorphic to its dual $G^*$), the model has a zero-temperature critical point with central charge $c=1$, and it is disordered at all positive temperatures. If $Γ$ is of non-self-dual type (i.e., if $G$ is not isomorphic to $G^*$), three ordered phases coexist at low temperature, and the model is disordered at high temperature. In addition, there is a finite-temperature critical point (separating these two phases) which belongs to the universality class of the ferromagnetic 3-state Potts model with central charge $c=4/5$. We have checked these conjectures by studying four (resp. seven) quadrangulations of self-dual (resp. non-self-dual) type, and using three complementary high-precision techniques: Monte-Carlo simulations, transfer matrices, and critical polynomials. In all cases, we find agreement with the conjecture. We have also found that the Wang-Swendsen-Kotecky Monte Carlo algorithm does not have (resp. does have) critical slowing down at the corresponding critical point on quadrangulations of self-dual (resp. non-self-dual) type.

description: We discuss Inönü-Wigner contractions of affine Kac-Moody algebras. We show that the Sugawara construction for the contracted affine algebra exists only for a fixed value of the level $k$, which is determined in terms of the dimension of the uncontracted part of the starting Lie algebra, and the quadratic Casimir in the adjoint representation. Further, we discuss contractions of $G/H$ coset spaces, and obtain an affine {\it translation} algebra, which yields a Virasoro algebra (via a GKO construction) with a central charge given by $dim(G/H)$.

Lidar Simulation for Robotic Application Development: Modeling and Evaluation

description: Given the increase in scale and complexity of robotics, robot application development is challenging in the real world. It may be expensive, unsafe, or impractical to collect data, or test systems, in reality. Simulation provides an answer to these challenges. In simulation, data collection is relatively inexpensive, scenes can be procedurally generated, and state information is trivially available. Despite these benefits, the use of simulators is often limited to the early stages of application development. In this work, we take steps to close the gap between simulation and reality, for Lidar simulation. We adopt the perspective that the eventual purpose of a simulator is a tool for robot application development. Our framework for sensor simulation consists of three components. The first is sensor modeling, which describes how a sensor interacts with a scene. The second is scene generation, needed to construct simulated worlds corresponding to reality. The third is simulator evaluation, based on comparing real and simulated data. We formalize the intuition that application performance must be similar in simulation and reality, using an application-level loss. Our framework is broadly applicable to simulating sensors other than Lidars. We instantiate our framework for two domains. The first domain is planar Lidar simulation in indoor scenes. We construct a high-fidelity simulator using a parametric sensor model. We show how application development paths for our simulator are closer to reality, compared to a baseline. We also pose sensor modeling as a case of distribution regression, which leads to a novel application of a nonparametric method that adapts to trends in sensor data. The second domain is Lidar simulation in o -road scenes. Our approach is to build a library of terrain primitives, derived from real Lidar observations. These are shown to generalize, resulting in an expressive simulator for complex o -road scenes. For this domain as well, we quantitatively demonstrate that our simulator is better for application development, compared to a baseline. Our work suggests a generic approach to building useful simulators. We view them as predictive models, and perform thorough tests on real data. We evaluate them with an application-level loss, which supports their greater use in the development cycle.
The Ratio of Helium- to Hydrogen-Atmosphere White Dwarfs: Direct Evidence for Convective Mixing

description: We determine the ratio of helium- to hydrogen-atmosphere white dwarf stars as a function of effective temperature from a model atmosphere analysis of the infrared photometric data from the Two Micron All Sky Survey combined with available visual magnitudes. Our study surpasses any previous analysis of this kind both in terms of the accuracy of the Teff determinations as well as the size of the sample. We observe that the ratio of helium- to hydrogen-atmosphere white dwarfs increases gradually from a constant value of ~0.25 between Teff = 15,000 K and 10,000 K to a value twice as large in the range 10,000 > Teff > 8000 K, suggesting that convective mixing, which occurs when the bottom of the hydrogen convection zone reaches the underlying convective helium envelope, is responsible for this gradual transition. The comparison of our results with an approximate model used to describe the outcome of this convective mixing process implies hydrogen mass layers in the range log M_H/M_tot = -10 to -8 for about 15% of the DA stars that survived the DA to DB transition near Teff ~ 30,000 K, the remainder having presumably more massive layers above log M_H/M_tot ~ -6.

This method consists of sending optical pulses using different combinations of modes though the multimode optical fiber and measuring the mode group delay at the fiber output. From these measurements, it is possible to estimate the modal dispersion vector, the principal modes, and their corresponding differential mode group delays. In this paper, we revise and extend the theoretical framework of the mode-dependent signal delay method to include the impact of receiver noise and mode-dependent loss. We compute optimal launch modes, minimizing the noise error in the estimation of the fiber modal dispersion vector. We show that, for a 40-mode fiber, the electronic signal-to-noise ratio (SNR) is improved asymptotically by almost 6 dB compared to conventional mode combinations.

description: The ``local'' structure of a quantum group G_q is currently considered to be an infinite-dimensional object: the corresponding quantum universal enveloping algebra U_q(g), which is a Hopf algebra deformation of the universal enveloping algebra of a n-dimensional Lie algebra g=Lie(G). However, we show how, by starting from the generators of the underlying Lie bialgebra (g,δ), the analyticity in the deformation parameter(s) allows us to determine in a unique way a set of n ``almost primitive'' basic objects in U_q(g), that could be properly called the ``quantum algebra generators''. So, the analytical prolongation (g_q,Δ) of the Lie bialgebra (g,δ) is proposed as the appropriate local structure of G_q. Besides, as in this way (g,δ) and U_q(g) are shown to be in one-to-one correspondence, the classification of quantum groups is reduced to the classification of Lie bialgebras. The su_q(2) and su_q(3) cases are explicitly elaborated.

description: We report on atomic-scale visualization of the structure of infinite-layer cuprate SrCuO2 thin films grown on Nb-doped SrTiO3 substrates by molecular beam epitaxy. In-situ scanning tunneling microscopy study reveals stoichiometric copper oxide (CuO2) plane with a 2 x 2 surface reconstruction, prompted by preferential clustering of four adjacent CuO2 plaquettes. By imaging the subsurface Sr atoms, intra-unit-cell rotational symmetry breaking is observed, which, together with the adjacent CuO2 clustering, can be well accounted for by a periodic up-down buckling of oxygen ions on the CuO2 plane. Further post-annealing leads to an incommensurate stripe structure of the surface layer. Our findings provide important structural information for deeply understanding the electronic structure of superconducting CuO2 plane as well as high temperature superconductivity in cuprates.

description: Narrow membrane tubes are commonly pulled out from the surface of phospholipid vesicles using forces applied either through laser or magnetic tweezers or through the action of processive motor proteins. Recent examples have emerged where such tubes spontaneously grow from vesicles coated with bioactive cytoskeletal filaments (e.g. FtsZ, microtubule) in the presence GTP. We show how a soft vesicle deforms due to the interplay between its topology, local curvature and the forces due to the active filaments. We present results from Dynamically Triangulated Monte Carlo simulations of a spherical continuum membrane coated with a nematic field and show how the intrinsic curvature of the filaments and their ordering interactions drive membrane tubulation. We predict interesting patterns of nematic defects, on curved 2D membrane surfaces, which promote tube formation. Implication of our model for more dynamic cases where vesicles coated with an active mixture of microtubule and myosin show shape oscillation, are also discussed. All these cases point to a common theme that defect locations on 2D membrane surfaces are hot spots of membrane deformation activity.

description: We reconsider the periodically driven two level system and especially the Rabi problem with linear polarization. The Floquet theory of this problem can be reduced to its classical limit, i.e., to the investigation of periodic solutions of the classical Hamiltonian equations of motion in the Bloch sphere. The quasienergy is essentially the action integral over one period and the resonance condition due to J.H. Shirley is shown to be equivalent to the vanishing of the time average of a certain component of the classical solution. This geometrical approach is applied to obtain analytical approximations to physical quantities of the Rabi problem with linear polarization as well as asymptotic formulas for various limit cases.

description: Disorder in two-band superconductors with repulsive interband interaction induces a frustrated competition between the phase-locking preferences of the various potential and kinetic terms. This frustrated interaction can result in the formation of an $s+is$ superconducting state, that breaks the time-reversal symmetry. In this paper we study the normal modes and their associated coherence lengths in such materials. We especially focus on the consequences of the soft modes stemming from the frustration and time-reversal-symmetry breakdown. We find that two-bands superconductors with such impurity-induced frustrated interactions display a rich spectrum of physical properties that are absent in their clean counterparts. It features a mixing of Leggett's and Anderson-Higgs modes, and a soft mode with diverging coherence length at the impurity-induced second order phase transition from $s_{\pm}/s_{++}$ states to the $s+is$ state. Such a soft mode generically results in long-range attractive intervortex forces that can trigger the formation of vortex clusters. We find that, if such clusters are formed, their size and internal flux density have a characteristic temperature dependence that could be probed in muon-spin-rotation experiments. We also comment on the appearance of spontaneous magnetic fields due to spatially varying impurities.

description: Additional symmetries of the $p$-reduced KP hierarchy are generated by the Lax operator $L$ and another operator $M$, satisfying $res (M^n L^{m+n/p})$ = 0 for $1 \leq n \leq p-1$ and $m \geq -1$ with the condition that ${\partial L \over {\partial t_{kp}}}$ = 0, $k$ = 1, 2,..... We show explicitly that the generators of these additional symmetries satisfy a closed and consistent W-algebra only when we impose the extra condition that ${\partial M \over {\partial t_{kp}}} = 0$.

description: Hydrogen Balmer lines are commonly used as spectroscopic effective temperature diagnostics of late-type stars. However, the absolute accuracy of classical methods that are based on one-dimensional (1D) hydrostatic model atmospheres and local thermodynamic equilibrium (LTE) is still unclear. To investigate this, we carry out 3D non-LTE calculations for the Balmer lines, performed, for the first time, over an extensive grid of 3D hydrodynamic STAGGER model atmospheres. For H$α$, H$β$, and H$γ$, we find significant 1D non-LTE versus 3D non-LTE differences (3D effects): the outer wings tend to be stronger in 3D models, particularly for H$γ$, while the inner wings can be weaker in 3D models, particularly for H$α$. For H$α$, we also find significant 3D LTE versus 3D non-LTE differences (non-LTE effects): in warmer stars ($T_{\text{eff}}\approx6500$K) the inner wings tend to be weaker in non-LTE models, while at lower effective temperatures ($T_{\text{eff}}\approx4500$K) the inner wings can be stronger in non-LTE models; the non-LTE effects are more severe at lower metallicities. We test our 3D non-LTE models against observations of well-studied benchmark stars. For the Sun, we infer concordant effective temperatures from H$α$, H$β$, and H$γ$; however the value is too low by around 50K which could signal residual modelling shortcomings. For other benchmark stars, our 3D non-LTE models generally reproduce the effective temperatures to within $1σ$ uncertainties. For H$α$, the absolute 3D effects and non-LTE effects can separately reach around 100K, in terms of inferred effective temperatures. For metal-poor turn-off stars, 1D LTE models of H$α$ can underestimate effective temperatures by around 150K. Our 3D non-LTE model spectra are publicly available, and can be used for more reliable spectroscopic effective temperature determinations.

description: The evidence of a new population of diffuse high-energy neutrinos, obtained by IceCube, has opened a new era in the field of neutrino physics. Up to now the events detected are still without any source counterpart. The detected events are compatible with the standard picture of cosmic neutrinos undergoing 3-flavor neutrino oscillations. We analyze the implications of neutrino oscillations for the present and future experiments, focusing particularly on tau neutrinos. In fact tau neutrinos are very important: even if they are not produced in astrophysical sites, they have to exist due to oscillations and their observation should be regarded as a basic proof in support of this scenario. Moreover, IceCube's measurement of the flux of muon neutrinos implies that the flux of tau neutrinos is measured within $20\%$, just assuming standard neutrino oscillations. On this basis, after discussing the experimental signatures of tau neutrinos, we predict the rates for $ν_τ$ detection in the present and future neutrino telescopes. We show that the present IceCube detector is close to observe the first tau neutrinos, with a probability of about 90\%. Moreover the next generation of IceCube can identify about 2 neutrinos per year, reaching an evidence of 5$σ$ in about 10 years, despite the present uncertainty on the spectrum and on the production mechanism. The non observation of these neutrino events would have dramatic implications, such as the questioning of cosmic neutrino observations or the violation of neutrino oscillations over cosmological scales.
