description: We study the effects of the perpendicular magnetic and Aharonov-Bohm (AB) flux fields on the energy levels of a two-dimensional (2D) Klein-Gordon (KG) particle subjects to equal scalar and vector pseudo-harmonic oscillator (PHO). We calculate the exact energy eigenvalues and normalized wave functions in terms of chemical potential parameter, magnetic field strength, AB flux field and magnetic quantum number by means of the Nikiforov-Uvarov (NU) method. The non-relativistic limit, PHO and harmonic oscillator solutions in the existence and absence of external fields are also obtained.

description: The coordination of actions and the allocation of profit in supply chains under decentralized control play an important role in improving the profits of retailers and suppliers in the chain. We focus on supply chains under decentralized control in which noncompeting retailers can order from multiple suppliers to replenish their stocks. Suppliers' production capacity is bounded. The goal of the firms in the chain is to maximize their individual profits. As the outcome under decentralized control is inefficient, coordination of actions between cooperating agents can improve individual profits. Cooperative game theory is used to analyze cooperation between agents. We define multi-retailer-supplier games and show that agents can always achieve together an optimal profit and they have incentives to cooperate and to form the grand coalition. Moreover, we show that there always exist stable allocations of the total profit among the firms upon which no coalition can improve. Then we propose and characterize a stable allocation of the total surplus induced by cooperation.

description: Building robust instruments capable of making interferometric measurements with precision beyond the standard quantum limit remains an important goal in many metrology laboratories. We describe here the basic concepts underlying spin squeezing experiments that allow one to surpass this limit. In priniciple it is possible to reach the so-called Heisenberg limit, which constitutes an improvement in precision by a factor $\sqrt{N}$, where $N$ is the number of particles on which the measurement is carried out. In particular, we focus on recent progress toward implementing spin squeezing with a cloud of beryllium ions in a Penning ion trap, via the geometric phase gate used more commonly for performing two-qubit entangling operations in quantum computing experiments.

description: The axiomatic theory of ordinary differential equations, owing to its simplicity, can provide a useful framework to describe various generalizations of dynamical systems. In this study, we consider how dynamical properties can be generalized to this setting. First, we study the generalizations of dynamical properties, such as invariance and limit sets and show that compact weakly invariant sets can be characterized in terms of the corresponding shift-invariant sets in the function space. This result enables us to consider weakly invariant sets in terms of shift-invariant sets. Next, we compare the axiomatic theory of ODE with other formalisms of generalized dynamical systems, namely generalized semiflow and multivalued semigroup. Finally, we introduce the notion of invariant measures and show that we can generalize classical results, such as Poincaré recurrence theorem.

Exploring biological risk factors of chronic obstructive pulmonary disease : old age and female sex
Creators: name: Mui, Tammy
Publisher: name: University of British Columbia
Year: 2010

description: Chronic obstructive pulmonary disease (COPD) has various risk factors including old age and female sex; however, the biological reasoning behind these is not fully understood. COPD prevalence and mortality increase with age. COPD patients also seem to demonstrate pulmonary and systemic accelerated aging. When people age, repetitive sequences at their chromosomes ends, called telomeres, shorten. In COPD this may occur at an increased rate due to increased cell turnover or DNA damage, caused by inflammation and oxidative stress, and could contribute to lung function decline. Therefore, we measured telomere length in peripheral blood cells of COPD patients using qPCR and examined the relationship with lung function (FEV₁ % predicted, FVC % predicted and FEV₁/FVC) as well as inflammatory marker levels. We found that telomere length was positively related to FEV₁/FVC and negatively related to serum SP-D level, a lung specific marker of inflammation. This supports that COPD is a disease of accelerated aging and suggests that lung inflammation may be involved in the process. Females seem to be more susceptible to developing COPD than males. A major distinction between males and females is their sex hormone levels. The lung has sex hormone receptors and there are reports of experimental animal studies and observational human studies suggesting that sex hormones have an effect on the lung. Hence, in COPD patients we measured levels of the hormones estradiol, progesterone, testosterone, luteinizing hormone, follicle-stimulating hormone and sex hormone-binding globulin in their serum using ELISAs. The hormone levels of COPD patients fell within normal ranges and had expected relationships with age and BMI. We found a significant negative association between estradiol and FVC % predicted in males; an inverse relationship between progesterone and FVC % predicted in both sexes; and a positive relationship between LH concentration and FEV₁ % predicted in females. These data support that sex hormones affect lung function, though the mechanism by which they do so is unclear due to the scarcity of knowledge in the field. Telomeres and sex hormones seem to play a role in the risk factors of aging and female sex, respectively, and offer insight into COPD pathogenesis, though more research is needed.

description: The demands of modern education on standardized performance pull us further and further away from a sophisticated and nuanced understanding of what it means to teach. Simple explanations of teaching and learning now run like this: excellent instruction leads to excellent learning, which is correlated with high test scores. Low test scores are a clear indication that poor instruction leads to poor learning. The voices of instructors and students are being marginalized, and we are losing sight of what it means to educate as less time, money, space, and value are allocated to a more complicated idea of education.

description: The detection of small objects is a challenging task in computer vision. Conventional object detection methods have difficulty in finding the balance between high detection and low false alarm rates. In the literature, some methods have addressed this issue by enhancing the feature map responses, but without guaranteeing robustness with respect to the number of false alarms induced by background elements. To tackle this problem, we introduce an $\textit{a contrario}$ decision criterion into the learning process to take into account the unexpectedness of small objects. This statistic criterion enhances the feature map responses while controlling the number of false alarms (NFA) and can be integrated into any semantic segmentation neural network. Our add-on NFA module not only allows us to obtain competitive results for small target and crack detection tasks respectively, but also leads to more robust and interpretable results.
Chiral Symmetry Breaking in Graphene

description: The question of whether the Coulomb interaction is strong enough to break the sublattice symmetry of un-doped graphene is discussed. We formulate a strong coupling expansion where the ground state of the Coulomb Hamiltonian is found exactly and the kinetic hopping Hamiltonian is treated as a perturbation. We argue that many of the properties of the resulting system would be shared by graphene with a Hubbard model interaction. In particular, the best candidate sublattice symmetry breaking ground state is an antiferromagnetic Mott insulator. We discuss the results of some numerical simulations which indicate that the Coulomb interaction is indeed subcritical. We also point out the curious fact that, if the electron did not have spin degeneracy, the tendency to break chiral symmetry would be much greater and even relatively weak Coulomb interactions would likely gap the spectrum.

description: We show how the general and basic asymmetry between two fundamental degrees of freedom present in strongly correlated oxides, spin and orbital, has very profound repercussions on the elementary spin and orbital excitations. Whereas the magnons remain largely unaffected, orbitons become inherently coupled with spin fluctuations in spin-orbital models with antiferromagnetic and ferroorbital ordered ground states. The composite orbiton-magnon modes that emerge fractionalize again in one dimension, giving rise to spin-orbital separation in the peculiar regime where spinons are faster than orbitons.

description: We applied canonical transformation to water wave equation not only to remove cubic nonlinear terms but to simplify drastically fourth order terms in Hamiltonian. This transformation explicitly uses the fact of vanishing exact four waves interaction for water gravity waves for 2D potential fluid. After the transformation well-known but cumbersome Zakharov equation is drastically simplified and can be written in X-space in compact way. This new equation is very suitable as for analytic study as for numerical simulation. Localized in space breather-type solution was found. Numerical simulation of collision of two such breathers strongly supports hypothesis of integrability of 2-D free surface hydrodynamics.

Verbunden damit ist die Erinnerung an Erwerbsarbeit, die um Bergleute und Stahlarbeiter geformt ist, die ihre Jobs im Niedergang der Kohle- und Stahlindustrie verloren. Heute wird das Ruhrgebiet als Vorbild für einen erfolgreichen Übergang vom sekundären zum tertiären Sektor dargestellt. Doch dies ist nur die eine Seite der Medaille: Denn mit der Erzählung des gemeisterten Strukturwandels ist ein starker Gender Bias dafür verantwortlich, dass andere Branchen, in denen ebenfalls ein Rückgang zu beobachten war, vernachlässigt wurden.

description: Intergalactic magnetic fields are assumed to have been spontaneously generated at the reheating stage of the early Universe, due to vacuum polarization of non-Abelian gauge fields at high temperature. The fact that the screening mass of this type of fields has zero value was discovered recently. A procedure to estimate their field strengths, $B(T)$, at different temperatures is here developed, and the value $B(T_{ew}) \sim 10^{14} G$ at the electroweak phase transition temperature, is derived by taking into consideration the present value of the intergalactic magnetic field strength, $B_0 \sim 10^{- 15} G$, coherent on the $\sim 1$ Mpc scale. As a particular case, the standard model is considered and the field scale at high temperature is estimated in this case. Model dependent properties of the phenomena under investigation are briefly discussed, too.

Additionally, we evaluate its ability to find ground and thermal equilibrium states.

description: Using the extended Poincaré-Lighthill-Kuo (PLK) reductive perturbation method, which incorporates the phase-shift variations, it is shown that common features on propagation and head-on collisions of ion-acoustic waves exist for a magnetized plasmas of different inertial-less particle distributions. For instance it is remarked that, the soliton amplitude is always independent of magnetic field strength while strictly depends on its angle regarding the propagation direction. Both types of solitons (compressive or rarefactive) are shown to exist which are defined through the critical angle $γ=π/2$ or other critical values depending on plasma fractional parameters. These critical plasma parameter values also define the sign of head-on collision phase shift. Furthermore, it is proved that for a given set of plasma parameters there is always a relative angle of propagation regarding to that of the magnetic-field for which the soliton width is maximum. Current findings applies to a wide range of magnetized plasmas including those containing background dust ingredients or two-temperature inertial-less particles and may be used to study laboratory or astrophysical magnetoplasmas.

description: The nature of the conducting filaments in many resistive switching systems has been elusive. Through in situ transmission electron microscopy, we image the real-time formation and evolution of the filament in a silicon oxide resistive switch. The electroforming process is revealed to involve the local enrichment of silicon from the silicon oxide matrix. Semi-metallic silicon nanocrystals with structural variations from the conventional diamond cubic form of silicon are observed, which likely accounts for the conduction in the filament. The growth and shrinkage of the silicon nanocrystals in response to different electrical stimuli show energetically viable transition processes in the silicon forms, offering evidence to the switching mechanism. The study here also provides insights into the electrical breakdown process in silicon oxide layers, which are ubiquitous in a host of electronic devices.

Metadata

description: To ensure that the PrecisionTox generated (meta)data is Findable, Accessible, Interoperable and Reusable (FAIR) [1] at source and remains discoverable, a principled approach has been developed to bootstrap metadata management. It takes advantage of a consolidated experimental design with unambiguous declaration of experimental variables, and the availability of software component engineered to exploit such information. This approach provides a programmatic way to generate standard-compliant metadata records, which appropriately and meaningfully track the experimental information and the related variables, such as species (5 organisms spanning large evolutionary distances), exposures (made with 250 chemicals), dose levels and time points post exposure. This standard-compliant collection of metadata records also ease of deposition to established public repositories for Next Generation Sequencing (NGS) and Mass Spectrometry (MS)-based metabolomics. Ongoing work will integrate metadata records with robotic platforms used in sample handling, data acquisition pathways, and deposition to recommended data archives.

description: For any system $\{i\}$ of particles with the trajectories $x_{i}(t)$ in $R^{d}$ on a finite time interval $[0,τ]$ we define the interaction graph $G$. Vertices of $G$ are the particles, there is an edge between two particles $i,j$ iff for some $t\in[0,τ]$ the distance between particles $i,j$ is not greater than some constant. We undertake a detailed study of this graph for infinite particle dynamics and prove exponential estimates for its finite connected components. This solves continuous percolation problem for a complicated geometrical objects - the tubes around particle trajectories.

description: Quantum-optimal discrimination between one and two closely separated light sources can be achieved by ideal spatial-mode demultiplexing, simply monitoring whether a photon is detected in a single antisymmetric mode. However, we show that for any, no matter how small, imperfections of the demultiplexer, this simple statistical test becomes practically useless, i.e. as good as flipping a coin. While we identify a class of separation-independent tests with vanishing error probabilities in the limit of large numbers of detected photons, they are generally unreliable beyond that very limit. As a practical alternative, we propose a simple semi-separation-independent test, which provides a method for designing reliable experiments, through arbitrary control over the maximal probability of error.

Publisher: name: Zenodo
Year: 2023

description: The mechanical stability of proteins is crucial for biological processes. To understand the mechanical functions of proteins, it is important to know the protein structure and mechanical properties. Protein mechanics is usually investigated through force spectroscopy experiments and simulations that probe the forces required to unfold the protein of interest.    While there is a wealth of data in the literature on force spectroscopy experiments and steered molecular dynamics simulations of forced protein unfolding, this information is spread and difficult to access by non-experts. Here we introduce MechanoProDB, a novel web-based database resource for collecting and mining data obtained from experimental and computational works. MechanoProDB provides a curated repository for a wide range of proteins, including muscle proteins, adhesion molecules and membrane proteins. The database incorporates relevant parameters that provide insights into the mechanical stability of proteins and their conformational stability such as the unfolding forces, energy landscape parameters and contour lengths of unfolding steps. Additionally, it provides intuitive annotations of the unfolding pathways of each protein, allowing users to explore the individual steps during mechanical unfolding. The user-friendly interface of MechanoProBD allows researchers to efficiently navigate, search and download data pertaining to specific protein folds or experimental conditions. Users can visualize protein structures using interactive tools integrated within the database, such as Mol*, and plot available data through integrated plotting tools. To ensure data quality and reliability, we have carefully manually verified and curated the data currently available on MechanoProDB. Furthermore, the database also features an interface that enables users to contribute new data and annotations, promoting community-driven comprehensiveness. The freely available MechanoProDB aims to streamline and accelerate research in the field of mechanobiology and biophysics by offering a unique platform for data sharing and analysis. MechanoProDB is freely available at https://mechanoprodb.ibdm.univ-amu.fr.

description: We propose the “Habitat Persistence Hypothesis” (HPH) to explain patterns of diversity on tropical coral-reefs. We reviewed distributions of organisms inhabiting tropical coral reefs, and formulated the HPH to account for biogeographical patterns on both shallow (<30m) and deep (30–150m) coral-reef habitats. Species occurring on deep reefs appear to show higher rates of endemism and less eastward diversity attenuation than their counterparts on shallow reefs. The HPH stipulates that shallow-reef habitats persist across glacio-eustatic sea-level changes in regions with sloped bathymetry (e.g., continental regions and large islands), but are largely extirpated during low sea-level stands in regions with steep bathymetry (e.g., coral atolls); in contrast to deep-reef habitats, which persist in all regions. The HPH suggests that habitat persistence results in higher rates of endemism, and attenuating diversity with distance from centers of species richness are shaped by recolonization from areas with shallow-habitat persistence. Whereas existing hypotheses that attempt to explain biogeographical patterns rely on observations limited to shallow (<30m) coral-reef habitat and invoke processes operating on speciation time-scales (~107), the HPH includes patterns on the remaining 80% of coral-reef habitat (30–150m) and invokes processes operating on time scales associated with sea-level changes (~105yr). The HPH posits seven specific predictions that can be directly tested to distinguish its role from existing coral-reef biogeographic hypotheses.

description: Public health infrastructure (PHI) serves as the core foundation for essential public health and its services. However, the U.S. PHI has been weakened by understaffing, underfunding, limited resources and partnerships, and outdated data and information systems over the past few decades. The recent COVID-19 pandemic exacerbated its vulnerability and weakened nature, resulting in increased health disparities and worse health outcomes in general for the nation. The goal of this study was to identify elements of local PHI that are associated with the completion of 20 key public health activities while adjusting for state differences. Cross-sectional secondary data were acquired and linked from two national surveys of local health departments, the National Profile of Local Health Departments survey and the National Longitudinal Survey of Public Health Systems. In total, 20 multivariable logistic regression models were created to analyze the relationships between variables. State fixed effects were used in multivariable models to control for state differences. It was found that state differences affected the correlations of infrastructure variables. Several staffing elements, abilities to provide certain services, and participation in certain types of actions were strongly correlated with the completion of best practice activities. These findings will add to the discussion of what the minimum necessary elements of PHI may be.

description: The magneto-phonon resonance or MPR occurs in semiconductor materials when the energy spacing between Landau levels is continuously tuned to cross the energy of an optical phonon mode. MPRs have been largely explored in bulk semiconductors, in two-dimensional systems and in quantum dots. Recently there has been significant interest in the MPR interactions of the Dirac fermion magnetoexcitons in graphene, and a rich splitting and anti-crossing phenomena of the even parity E2g long wavelength optical phonon mode have been theoretically proposed and experimentally observed. The MPR has been found to crucially depend on disorder in the graphene layer. This is a feature that creates new venues for the study of interplays between disorder and interactions in the atomic layers. We review here the fundamentals of MRP in graphene and the experimental Raman scattering works that have led to the observation of these phenomena in graphene and graphite.

description: Thanks to the progress in neutrino-detection techniques, geoneutrinos, antineutrinos from the decays of long-lived radioactive elements inside the Earth, can be detected and exploited as a unique tool to study our planet. Geoneutrinos from the 238U and 232Th radioactive chains with energies above 1.8 MeV were measured by the KamLAND experiment in Japan and the Borexino experiment in Italy, exploiting the charge-current inverse-beta decay interaction on protons. Both detectors are located underground and feature large volume liquid scintillator target. The most relevant backgrounds to geoneutrino measurement are represented by reactor antineutrinos, residual muon flux, and intrinsic radioactivity of the detector. Both experiments reached similar precision of the geoneutrino signal measurement in the range of 15 to 18% and confirmed a general consistency of the measured signal with the geological expectations. Due to the different geological settings and geographical locations, their results are complementary. Assuming a laterally homogeneous mantle, their measurements feature some level of tension: Borexino prefers geological models predicting higher U and Th abundances, while KamLAND favors their lower abundances. The talk will describe the key elements of the analysis, overview of the latest results and their geological interpretation, in terms of the corresponding radiogenic heat, geoneutrino signal from the Earth's mantle, and the limit to the hypothetical georeactor.

description: We investigate the relevance of quantum gravity during inflation to address the Hubble tension that arises from Planck 2018 and SH0ES data sets. We show that the effect of quantum gravity during inflation can increase the rate of change of $H_0$, thereby accounting for a wide range of observed $H_0$. Further, we show that due to the quantum gravity effect on inflation, the temperature at the onset of reheating can be lower than the standard case, causing delays in the reheating process. The role of quantum gravity is inevitable in settling the Hubble tension. The results of the present study may find use in resolving the Hubble tension, in validating inflationary model and quantum gravity.

Quantum numbers of the three-nucleon (3N) system are chosen to be (I, J^P)=(1/2, 1/2^+) (the triton channel). We consider the simplest geometrical configuration where 3N are aligned linearly with an equal spacing, to reduce the enormous computational cost. Lattice QCD simulations are performed using Nf=2 dynamical clover fermion configurations at the lattice spacing of a = 0.156 fm on a 16^3 x 32 lattice with a large quark mass corresponding to m(π) = 1.13 GeV. We find repulsive 3NF at short distance.

description: Research data services has been a dynamically evolving area in libraries over the past few years.  New opportunities have emerged for libraries to deliver data related instruction as institutions develop and offer data management services to respond to federally mandated research data management needs of campus communities.  The UC San Diego Library has developed instructional workshops to teach graduate students and researchers basic foundational computational skills that include using data analysis tools, such as R and Python, programming best practices, and how to employ reproducible research methods in data and code management.  The presenters will discuss how the library decided to target data instruction for graduate students, how we developed the workshops, how we developed ourselves to be able to teach these skills and what we learned from our initial feedback from our first year offering them. We will discuss our thoughts about how teaching these workshops is an important way a library can engage with the research enterprise on a campus.  We will discuss our future affiliation with Software Carpentry and how we plan on targeting departments/schools on campus to develop audiences, collaborators and advocates for the programmatic growth of the workshop offerings. In this manner, we hope to engage a discussion with participants on how best a library can help meet the increasing demand for basic scientific computing programming skills across research disciplines and how that can be an opportunity for new librarian roles.

description: We address the problem of the robustness of entanglement of bipartite systems (qubits) interacting with dynamically independent environments. In particular, we focus on characterization of so-called local entanglement-annihilating two-qubit channels, which set the maximum permissible noise level allowing to perform entanglement-enabled experiments. The differences, but also subtle relations between entanglement-breaking and local entanglement-annihilating channels are emphasized. A detailed characterization of latter ones is provided for a variety of channels including depolarizing, unital, (generalized) amplitude-damping, and extremal channels. We consider also the convexity structure of local entanglement-annihilating qubit channels and introduce a concept of entanglement-annihilation duality.

description: We explore the non-equilibrium dynamics of a one-dimensional Fermi-Hubbard system as a sensitive testbed for the capabilities of the time-dependent two-particle reduced density matrix (TD2RDM) theory to accurately describe time-dependent correlated systems. We follow the time evolution of the out-of-equilibrium finite-size Fermi-Hubbard model initialized by a quench over extended periods of time. By comparison with exact calculations for small systems and with matrix product state (MPS) calculations for larger systems but limited to short times, we demonstrate that the TD2RDM theory can accurately account for the non-equilibrium dynamics in the regime from weak to moderately strong inter-particle correlations. We find that the quality of the approximate reconstruction of the three-particle cumulant (or correlation) required for the closure of the equations of motion for the reduced density matrix is key to the accuracy of the numerical TD2RDM results. We identify the size of the dynamically induced three-particle correlations and the amplitude of cross correlations between the two- and three-particle cumulants as critical parameters that control the accuracy of the TD2RDM theory when current state-of-the art reconstruction functionals are employed.

Modeling bilateral air services agreement for the purpose of measuring the economic effects of air transport liberalization : a case study of Canada and China
Creators: name: Song, Wei
Publisher: name: University of British Columbia
Year: 2010

description: International air services are mostly regulated by bilateral Air Services Agreements (ASAs) signed by each pair of countries. Most of the bilateral ASAs are still operated within the framework of the Chicago Convention, and considered to be restrictive and inefficient to serve international air markets. Over the last two decades, the United States, European Union, and some other countries have pioneered liberalization of bilateral ASAs and received remarkable positive results. Although Canadian government released a “Blue Sky” policy in 2006 to pursue negotiation of Open Skies-type agreements, many of the major air markets, such as the Canada—China market, are still regulated by restricted ASAs. Whether or not to liberalize bilateral ASAs and what are the impacts of liberalization has become an interest to airlines, investors, consumers and regulators. However, the existing studies are insufficient for understanding the magnitudes of potential impacts of such liberalization, and, hence, to provide direct insights to policy makers. Therefore, there is a need for a new study for simulating potential economic effects of ASA liberalization. The primary objective of this thesis is to develop a computable model to estimate potential economic effects of bilateral ASA liberalization between Canada and China. In particular, this study aims to estimate how the market shares of the flag carriers would change and how the gains and losses would be changed among passengers and carriers in either country. To address these objectives, we compare the simulation results between the base case (2006 data without liberalization) and the case of liberalizing Canada-China ASA to a varying degree in order to estimate the impacts of the liberalization. The major findings are: (a) airfare would decrease with air liberalization, which would stimulate more passengers, and induce airlines to increase flight frequency. ; (b) in most of the cases, passengers carried by incumbent carriers would increase even if new airlines enter the routes; (c) although carriers’ profit would decrease, the aggregate economic welfare would increase because consumer benefits would increase dramatically; and (d) while any level of air liberalization would be positive, Open Skies would have the greatest impacts on both countries.
Molecular Clouds in Supershells: A Case Study of Three Objects in the Walls of GSH 287+04-17 and GSH 277+00+36

description: We present an in-depth case study of three molecular clouds associated with the walls of the Galactic supershells GSH 287+04-17 and GSH 277+00+36. These clouds have been identified in previous work as examples in which molecular gas is either being formed or destroyed due to the influence of the shells. 12CO(J=1-0), 13CO(J=1-0) and C18O(J=1-0) mapping observations with the Mopra telescope provide detailed information on the distribution and properties of the molecular gas, enabling an improved discussion of its relationship to the wider environment in which it resides. We find that massive star formation is occurring in molecular gas likely formed in-situ in the shell wall, at a Galactic altitude of ~200 pc. This second-generation star formation activity is dominating its local environment; driving the expansion of a small HII region which is blistering out of the atomic shell wall. We also find new morphological evidence of disruption in two smaller entrained molecular clouds thought to pre-date the shells. We suggest that at the present post-interaction epoch, the lifetime of this surviving molecular material is no longer strongly determined by the shells themselves.

description: A classical problem in electromagnetics concerns the representation of the electric and magnetic fields in the low-frequency or static regime, where topology plays a fundamental role. For multiply connected conductors, at zero frequency the standard boundary conditions on the tangential components of the magnetic field do not uniquely determine the vector potential. We describe a (gauge-invariant) consistency condition that overcomes this non-uniqueness and resolves a longstanding difficulty in inverting the magnetic field integral equation.

description: We experimentally obtained a direct image of the nuclear wave functions of {H_2}^+ by dissociating the molecule via electron attachment and determining the vibrational state using the COLTRIMS technique. Our experiment visualizes the nodal structure of different vibrational states. We compare our results to the widely used reflection approximation and to quantum simulations and discuss the limits of position measurements in molecules imposed by the uncertainty principle.
