description: In this paper, we study the relation between geodesic and harmonic mappings. Harmonic mappings are defined between Riemannian manifolds as critical points of the energy functional, on the other hand, geodesic mappings are defined in a more general setting (manifolds with affine connections). Using the well-established formalism of calculus of variations on fibred manifolds we solve the weak inverse problem for the equation of geodesic mappings and get a variational equation which is a consequence of the geodesic mappings equation. For the connection on the target manifold we get the expected result, that it is a metric connection. However, we find that the connection on the source manifold need not be metric. The interesting result is that the metric which induces the connection on the target manifold can change between fibres and these changes are related to the connection on the source manifold. These results hint onto a possibility for a more general structure on the fibred manifold, than usually assumed.

description: Climate anomalies, such as El Nino Southern Oscillation (ENSO), affect agricultural production in different parts of the world, and can impact price behavior of the internationally traded commodities. This study examines the effect of ENSO on wheat price dynamics of five major exporting regions -- USA, Canada, Australia, EU, and Argentina. While the prices are linked due to the law of one price and the arbitrage conditions, nonlinear price adjustments are expected, due to the transaction costs, the market power, derived asymmetries from supply shocks. This study addresses asymmetries in wheat price transmission in response to ENSO-related supply shocks, using univariate and multivariate smooth transition modelling frameworks. Results of this study confirm regime-dependent nonlinearities in ENSO cycles as well as the system of considered wheat prices, where regimes are conditioned on the state of nature of the ENSO anomaly. In general, positive ENSO shocks, i.e. El Nino-s, result in wheat price reduction, while negative ENSO shock, i.e. La Nina-s, results in increased wheat prices. Moreover, the asymmetric nature of the responses to ENSO shocks implies that the rates of price increases are, on average, larger as compared to the rates of price decreases.

description: This article examines factors driving technical change, technical efficiency, and scale and mix efficiency – all components of total factor productivity – in U.S. agriculture. We use economic theory and previous literature to identify explanatory variables affecting each component and examine some potentially important factors which have received less attention in the literature. Results show that technical change comes primarily from increased innovation through public research and from improvements in human capital. Technical efficiency is driven by farm size and the ratio of family to total labor, while scale and mix efficiency is driven mainly by agro-climatic conditions, weather, and farm size.

description: The present study extends neuro-imaging into conversation through studying dialogue comprehension. Conversation entails rapid responses, with negative semiotics for delay. We explored how expectations about the valence of the forthcoming response develop during the silence before the response and whether negative responses have mainly cognitive or social-emotional consequences. EEG-participants listened to questions from a spontaneous spoken corpus, cross-spliced with short/long gaps and “yes”/“no” responses. Preceding contexts biased listeners to expect the eventual response, which was hypothesised to translate to expectations for a shorter or longer gap. “No” responses showed a trend towards an early positivity, suggesting socio-emotional consequences. Within the long gap, expecting a “yes” response led to an earlier negativity, as well as a trend towards stronger theta-oscillations, after 300 milliseconds. This suggests that listeners anticipate/predict “yes” responses to come earlier than “no” responses, showing strong sensitivities to timing, which presumably promote hastening the pace of verbal interaction.

description: Although security questions are still widely adopted, they still have several limitations. Previous research found that using system-generated information to answer security questions could be more secure than users' own answers. However, using system-generated information has usability limitations. To improve usability, previous research proposed the design of system-generated fictitious profiles. The information from these profiles would be used to answer security questions. However, no research has studied the elements that could influence the design of fictitious profiles or systems that use them to answer security questions. To address this research gap, we conducted an empirical investigation through 20 structured interviews. Our main findings revealed that to improve the design of fictitious profiles, users should be given the option to configure the profiles to make them relatable, interesting and memorable. We also found that the security questions currently provided by websites would need to be enhanced to cater for fictitious profiles.

description: Is the recent evidence for a time-varying fine structure 'constant' $α$ to be interpreted as a varying $e$, $c$, $\hbar$, or a combination thereof? We consider the simplest varying electric charge and varying speed of light theories (VSL) and prove that for the same type of dark matter they predict opposite senses of variation in $α$ over cosmological times. We also show that unlike varying $e$ theories, VSL theories do not predict violations of the weak equivalence principle (WEP). Varying $e$ theories which explain astronomical inferences of varying $α$ predict WEP violations only an order of magnitude smaller than existing Eötvös experiment limits but could be decisively tested by STEP. We finally exhibit a set of atomic-clock and related experiments for which {\it all} (hyperbolic) varying $α$ theories predict non-null results. They provide independent tests of the recent astronomical evidence.

description: Image processing techniques powered by Machine Learning are revolutionizing the field of data analysis from particle physics detectors, as they allow powerful methods developed jointly in academia and in the industry to disentangle the complex data that detectors observe. Superimposed tracks of multiple particles, with cross-talk and noise, lead to intricacies that traditional methods such as likelihood-based Bayesian approaches can fail to properly handle, especially when the data volume becomes prohibitive for Markov Chain Monte Carlo (MCMC) simulations. 

In this context, the ETH IPA Neutrino group has an avant-garde strategy for the data analysis of the Near Detector (ND280) of the T2K experiment. Using Machine Learning image processing algorithms, it aims to further improve the reconstruction of particles of neutrino-nucleus interactions. To do so, we focused on three specific task of this problem: first identify the vertex activity region with a Convolutional Neural Network (CNN) on sparse tensors (we obtained 83\% score compared to  75\% with a decision tree); second fit the trajectory points of escaping particles with a transformer encoder (1.21 mm average distance to the truth compared to 3.06 mm with a Bayesian filter); third decompose the vertex activity region into individual particles with a transformer encoder-decoder (7.8 MeV resolution on up to 100 MeV protons, 13 MeV on both protons and neutrons). 

Our models demonstrate a clear superiority on standard methods used in the field, and we aspire to deploy them on the data analysis pipelines of ND280.

description: Understanding the pathophysiology of lung fibrosis is of paramount importance to elaborate targeted and effective therapies. As it onsets, the randomly accumulating extracellular matrix (ECM) breaks the symmetry of the branching lung structure. Interestingly, similar pathways have been reported for both idiopathic pulmonary fibrosis and radiation-induced lung fibrosis (RILF). Individuals suffering from the disease, the worldwide incidence of which is growing, have poor prognosis and a short mean survival time. In this context, mathematical and computational models have the potential to shed light on key underlying pathological mechanisms, shorten the time needed for clinical trials, parallelize hypotheses testing, and improve personalized drug development. Agentbased modeling (ABM) has proven to be a reliable and versatile simulation tool, whose features make it a good candidate for recapitulating emergent behaviors in heterogeneous systems, such as those found at multiple scales in the human body. In this paper, we detail the implementation of a 3D agent-based model of lung fibrosis using a novel simulation platform, namely, BioDynaMo, and prove that it can qualitatively and quantitatively reproduce published results. Furthermore, we provide additional insights on late-fibrosis patterns through ECM density distribution histograms. The model recapitulates key intercellular mechanisms, while cell numbers and types are embodied by alveolar segments that act as agents and are spatially arranged by a custom algorithm. Finally, our model may hold potential for future applications in the context of lung disorders, ranging from RILF (by implementing radiation-induced cell damage mechanisms) to COVID-19 and inflammatory diseases (such as asthma or chronic obstructive pulmonary disease).
Selecting Data to Clean for Fact Checking: Minimizing Uncertainty vs. Maximizing Surprise

description: We study the optimization problem of selecting numerical quantities to clean in order to fact-check claims based on such data. Oftentimes, such claims are technically correct, but they can still mislead for two reasons. First, data may contain uncertainty and errors. Second, data can be "fished" to advance particular positions. In practice, fact-checkers cannot afford to clean all data and must choose to clean what "matters the most" to checking a claim. We explore alternative definitions of what "matters the most": one is to ascertain claim qualities (by minimizing uncertainty in these measures), while an alternative is just to counter the claim (by maximizing the probability of finding a counterargument). We show whether the two objectives align with each other, with important implications on when fact-checkers should exercise care in selective data cleaning, to avoid potential bias introduced by their desire to counter claims. We develop efficient algorithms for solving the various variants of the optimization problem, showing significant improvements over naive solutions. The problem is particularly challenging because the objectives in the fact-checking context are complex, non-linear functions over data. We obtain results that generalize to a large class of functions, with potential applications beyond fact-checking.

description: We investigate the environmental effects due to pesticides for two different genetically modified (GM) seeds: insect resistant (IR) cotton and herbicide tolerant (HT) soybeans. Using an agricultural production model of a profit maximizing competitive farm, we derive predictions that IR trait decreases the amount of insecticides used and HT trait increases the amount of less toxic herbicides. While the environmental impact of pesticides for IR seeds is lower, for the HT seeds the testable predictions are ambiguous: scale as substitution effects can lead to higher environmental impacts. We use a dataset on commercial farms use of pesticides and biotechnology in Brazil to document environmental effects of GM traits. We explore within-farm variation for farmers planting conventional and GM seeds to identify the effect of adoption on the environmental impact of pesticides measured as quantity of active ingredients of chemicals and the Environmental Impact Quotient index. The findings show that the IR trait reduces the environmental impact of insecticides and the HT trait increases environmental impact due to weak substitution among herbicides of different toxicity levels.

description: For a special stochastic realistic model in certain spin-correlation experiments and without imposing the locality condition, an inequality is found. Then, it is shown that quantum theory is able (is possible) to violate this inequality. This shows that, irrelevance of the locality condition, the quantum entanglement of the spin singlet-state is the reason for the violation of Bell's inequality in Bell's theorem.

description: Cognitive Reserve (CR) refers to cognitive resources acquired through experiences along the lifespan that allow for flexibility in coping with neurocognitive changes. Investigating the role of CR measures across well-established psycholinguistic features can provide new insight into how CR interplays with cognition. Sixty-five Italian older adults performed a Lexical Decision, a Semantic Matching and a Sentence Reading task. We observed the effects of CR on reaction times and accuracy while varying lexical frequency (high vs low) and lexical semantics (concrete vs abstract) and on reading times of sentences with either syntactic or semantic violations. In the Lexical Decision and Semantic Matching tasks, CR played a role in processing low frequency and abstract words. In the Sentence Reading Task, CR influenced reading times, particularly in the presence of syntactic violations. CR predicts cognitive performance in tasks that require language demands at different levels.

description: We discuss a relation between the Kantorovich-Wasserstein (KW) metric and the Kullback-Leibler (KL) divergence. The former is defined using the optimal transport problem (OTP) in the Kantorovich formulation. The latter is used to define entropy and mutual information, which appear in variational problems to find optimal channel (OCP) from the rate distortion and the value of information theories. We show that OTP is equivalent to OCP with one additional constraint fixing the output measure, and therefore OCP with constraints on the KL-divergence gives a lower bound on the KW-metric. The dual formulation of OTP allows us to explore the relation between the KL-divergence and the KW-metric using decomposition of the former based on the law of cosines. This way we show the link between two divergences using the variational and geometric principles.

description: A study of the linearised gravitational field (spin 2 zero-rest-mass field) on a Minkowski background close to spatial infinity is done. To this purpose, a certain representation of spatial infinity in which it is depicted as a cylinder is used. A first analysis shows that the solutions generically develop a particular type of logarithmic divergence at the sets where spatial infinity touches null infinity. A regularity condition on the initial data can be deduced from the analysis of some transport equations on the cylinder at spatial infinity. It is given in terms of the linearised version of the Cotton tensor and symmetrised higher order derivatives, and it ensures that the solutions of the transport equations extend analytically to the sets where spatial infinity touches null infinity. It is later shown that this regularity condition together with the requirement of some particular degree of tangential smoothness ensures logarithm-free expansions of the time development of the linearised gravitational field close to spatial and null infinities.

description: In this paper we explore the potential improvements in neutrino event reconstruction that a 3D pixelated readout could offer over a 2D projective wire readout for liquid argon time projection chambers. We simulate and study events in two generic, idealized detector configurations for these two designs, classifying events in each sample with deep convolutional neural networks to compare the best 2D results to the best 3D results. In almost all cases we find that the 3D readout provides better reconstruction efficiency and purity than the 2D projective wire readout, with the advantages of 3D being particularly evident in more complex topologies, such as electron neutrino charged current events. We conclude that the use of a 3D pixelated detector could significantly enhance the reach and impact of future liquid argon TPC experiments physics program, such as DUNE.

description: Values for the bulk Witten indices for D=10 Yang-Mills integrals for some regular simple groups of rank 4 and 5 are calculated by employing the BRST deformation technique by Moore, Nekrasov and Shatashvili. The results cannot be reconciled with the double assumption that the number of normalizable ground states is given by certain simple partition functions given by Kac and Smilga as well as that the corresponding boundary term is always negative.

Symplectic Integration of Hamiltonian Systems using Polynomial Maps
Creators: name: Rangarajan, Govindan
Publisher: name: arXiv
Year: 2001
Subjects: subject: Exactly Solvable and Integrable Systems (nlin.SI)
subject: FOS: Physical sciences

description: In order to perform numerical studies of long-term stability in nonlinear Hamiltonian systems, one needs a numerical integration algorithm which is symplectic. Further, this algorithm should be fast and accurate. In this paper, we propose such a symplectic integration algorithm using polynomial map refactorization of the symplectic map representing the Hamiltonian system. This method should be particularly useful in long-term stability studies of particle storage rings in accelerators.

description: The number and variety of information systems (IS) certifications have increased continuously as the use of information technology has diversified and expanded. IS certifications are neutral third-party attestations of specific system characteristics and management principles to prove compliance with requirements. The reasons for organizations to adopt IS certifications are diverse, such as fostering learning and improvement, or demonstrating regulatory compliance. However, because of organizations’ diverse motivations to adopt certifications, organizations also differ in their degree of internalizing the certification. In particular, superficial, ceremonial adoption and a lack of internalization of certifications become critical issues harming the certification’s reputation and effectiveness. This short paper reports on preliminary findings from a qualitative study on the development of a data protection certification. Based on unique access to case companies throughout the certification attestation process, our research will provide insights into how motivations for adoption impact the internalization processes of organizations.

description: ANAIS (Annual modulation with NaI Scintillators) is a dark matter direct detection experiment located at the Canfranc Underground Laboratory (LSC), in Spain. The goal is to confirm or refute in a model independent way the DAMA/LIBRA positive result: an annual modulation in the low-energy detection rate compatible with the expected signal induced by dark matter particles in the galactic halo. This signal, observed for about 20 years, is in strong tension with the negative results of other very sensitive experiments, but a direct comparison using the same target material, NaI(Tl), was still lacking. ANAIS-112, consisting of 112.5 kg of NaI(Tl) scintillators, is taking data at the LSC since August 2017. Here we present the preliminary annual modulation analysis corresponding to two years of data (exposure of 220.69 kg x y) and the ANAIS-112 projected sensitivity for the scheduled 5 y of operation.

Noncommutative cohomology and electromagnetism on $C_q[SL_2]$ at roots of unity

description: We compute the noncommutative de Rham cohomology for the finite-dimensional q-deformed coordinate ring $C_q[SL_2]$ at odd roots of unity and with its standard 4-dimensional differential structure. We find that $H^1$ and $H^3$ have three additional modes beyond the generic $q$-case where they are 1-dimensional, while $H^2$ has six additional modes. We solve the spin-0 and Maxwell theory on $C_q[SL_2]$ including a complete picture of the self-dual and anti-self dual solutions and of Lorentz and temporal gauge fixing. The system behaves in fact like a noncompact space with self-propagating modes (i.e., in the absence of sources). We also solve with examples of `electric' and `magnetic' sources including the biinvariant element $θ\in H^1$ which we find can be viewed as a source in the local (Minkowski) time-direction (i.e. a uniform electric charge density).

description: The present study extends neuro-imaging into conversation through studying dialogue comprehension. Conversation entails rapid responses, with negative semiotics for delay. We explored how expectations about the valence of the forthcoming response develop during the silence before the response and whether negative responses have mainly cognitive or social-emotional consequences. EEG-participants listened to questions from a spontaneous spoken corpus, cross-spliced with short/long gaps and “yes”/“no” responses. Preceding contexts biased listeners to expect the eventual response, which was hypothesised to translate to expectations for a shorter or longer gap. “No” responses showed a trend towards an early positivity, suggesting socio-emotional consequences. Within the long gap, expecting a “yes” response led to an earlier negativity, as well as a trend towards stronger theta-oscillations, after 300 milliseconds. This suggests that listeners anticipate/predict “yes” responses to come earlier than “no” responses, showing strong sensitivities to timing, which presumably promote hastening the pace of verbal interaction.
Quantum memory for individual polarization photon

description: Here we present an experimentally feasible quantum memory for individual polarization photon with long-lived atomic ensembles excitations. Based a process similar to teleportation, the memory is reversible. And the storage information can be effortlessly read out and transferred back to photon. Although it successes with only a probability of 1/4, it is expected valuable in various quantum information processing, especially those cases where polarized photons are employed. The physical requirements are moderate and fit the presest technique.

description: We establish a holographic description of chiral symmetry breaking for a particular confining large N non-supersymmetric gauge theory with matter in the fundamental representation. The gravity dual of this theory is obtained by introducing a D7-brane probe into a deformed Anti-de Sitter background found by Constable and Myers. We numerically compute the \barψψcondensate and meson spectrum by solving the equation of motion of the D7-brane probe in this background. We find a symmetry breaking condensate as well as the associated, pion-like, Goldstone boson in the limit of small quark mass. The existence of the condensate ensures that the D7-brane never reaches the naked singularity at the origin of the deformed AdS space.

Climate variability can outweigh the influence of climate mean changes for extreme precipitation under global warming
Creators: name: Nordling, Kalle
name: Fahrenbach, Nora
name: Samset, Bjørn
Publisher: name: ETH Zurich
Year: 2024

description: As global warming progresses, weather conditions like daily temperature and precipitation are changing due to changes in their means and distributions of day-to-day variability. In this study, we show that changes in variability have a stronger influence on the number of extreme precipitation days than the change in the mean state in many locations. We analyze daily precipitation and maximum temperatures at four levels of global warming and under different emission scenarios for the Northern Hemisphere (NH) summer (June – August). Our analysis is based on initial condition large ensemble simulations from three fully coupled Earth System Models (MPI-ESM1-2-LR, CanESM5, and ACCESS-ESM1-5) contributing to the Climate Model Inter-comparison Project phase 6 (CMIP6). We also use information from the Precipitation Driver Response Model Intercomparison Project (PDRMIP) to discern the influence of different climate drivers (notably aerosols and greenhouse gases). We decompose the total changes in daily NH summer precipitation and daily maximum temperature into mean and variability components (standard deviation and skewness). Our results show that in many locations, variability exerts a stronger influence than mean changes on daily precipitation. Changes in the widths and shapes of precipitation distributions are especially dominating over mean changes in Asia, the Arctic and Sub-Saharan Africa. In contrast, temperature changes are primarily driven by changes in the mean state. For the near future (2020–2040), we find that reductions in aerosol emissions would increase the likelihood of extreme summertime precipitation only over Asia. This study emphasizes the importance of incorporating daily variability changes into climate change impact assessments and advocates that future emulator and impact model development should focus on improving the representation of daily variability.

description: In this paper, we investigate the existence of weak solution for a fractional type problems driven by a nonlocal operator of elliptic type in a fractional Orlicz-Sobolev space, with homogeneous Dirichlet boundary conditions. We first extend the fractional Sobolev spaces $W^{s,p}$ to include the general case $W^sL_A$, where $A$ is an N-function and $s\in (0,1)$. We are concerned with some qualitative properties of the space $W^sL_A$ (completeness, reflexivity and separability). Moreover, we prove a continuous and compact embedding theorem of these spaces into Lebesgue spaces.
