description: Cardiovascular disease (CVD) is the leading global cause of death and disability in women. Hypertension is an especially important risk factor for cardiovascular-related morbidity and mortality in women, who have additional sex-specific risk for CVD associated with hypertensive disorders of pregnancy (HDP). Despite robust evidence of a pathophysiologic relationship between chronic hypertension (HTN) and atrial fibrillation (AFib)– the most common sustained arrhythmia– there is limited and mixed evidence about the relationship between HDP and incident AFib. The primary aim of this thesis was to advance our understanding of the relationship between exposure to HDP in a first singleton delivery and incident AFib using population-based, linked, administrative data sources. However, several conceptual/methodological factors required consideration prior to undertaking this work, which were additionally addressed in three preliminary studies: a methodological guidance article, a systematic review of administrative case-finding definitions for HDP, and a population-based descriptive study of HDP prevalence in Ontario that tested/compared estimates generated using three different case-identification strategies. Most validated case-finding definitions identify HDP from administrative databases with high specificity (≥98%); however, their median sensitivity varies widely (3%-91%). Gestational hypertension was the most prevalent HDP subtype in primiparous Ontario women who delivered a live/stillborn singleton infant between 2002-2017 (~5%). However, the prevalence of any HDP is likely underestimated when these conditions are identified only using information from obstetrical discharge abstracts. Finally, people with a history of gestational hypertension, preeclampsia, or HTN in pregnancy in their first singleton delivery have a 1.5-2.2 times increased cause-specific hazard of incident AFib compared to their unexposed counterparts. Additional studies that account for the time-varying nature of HDP and relevant confounders are needed to further elucidate these associations. HDP can serve as an important warning sign for future CVD– including AFib– even before traditional risk factors become clinically apparent. Thesis findings highlight the critical need for (a) improved population-based surveillance of traditional and female-specific risk factors for CVD, (b) prevention strategies designed to reduce both the occurrence and severity of HDP, and (c) the consideration of reproductive and gynecologic history in CVD risk calculation and stratification– especially in younger women.

description: The Object Constraint Language (OCL) was originally designed as an `add-on' to the Unified Modelling Language (UML) in order to facilitate writing textual constraints complementing the graphical specifications. Since its original standardisation many extensions have been added to the language and many more have been proposed. The original structure of the OCL definition has not been formed, however, with a view of extensibility. Still, OCL can be redesigned in such a manner that it becomes easy to extend the language. In this paper we present a modular redefinition of OCL and illustrate how it supports extension. This new approach to the design of OCL enables you to consistently extend or customise OCL to your own needs.

description: Context: Recent spectropolarimetric observations of Herbig Ae/Be stars have yielded new arguments in favour of a fossil origin for the magnetic fields of intermediate mass stars. Aims: To study the evolution of these magnetic fields, and their impact on the evolution of the angular momentum of these stars during the pre-main sequence phase, we observed Herbig Ae/Be members of young open clusters of various ages. Methods: We obtained high-resolution spectropolarimetric observations of Herbig Ae/Be stars belonging to the young open clusters NGC 6611 (< 6 Myr), NGC 2244 (~1.9 Myr), and NGC 2264 (~8 Myr), using ESPaDOnS at theCanada-France-Hawaii Telescope. Results: Here we report the discovery of strong magnetic fields in two massive pre-main sequence cluster stars. We detected, for the first time, a magnetic field in a pre-main sequence rapid rotator: the 10.2 Msun Herbig B1.5e star W601 (NGC 6611; v sin i ~ 190 km/s). Our spectropolarimetric observations yield a longitudinal magnetic field larger than 1 kG, and imply a rotational period shorter than 1.7 days. The spectrum of this very young object (age ~ 0.017 Myr) shows strong and variable lines of He and Si. We also detected a magnetic field in the 12.1 Msun B1 star OI 201 (NGC 2244; v sin i = 23.5 km/s). The Stokes V profile of this star does not vary over 5 days, suggesting a long rotational period, a pole-on orientation, or aligned magnetic and rotation axes. OI 201 is situtated near the Zero-Age Main Sequence on the HR diagram, and exhibits normal chemical abundances and no spectrum variability.

Specifying Executable Platform-Independent Models using OCL

Publisher: name: European Association of Software Science and Technology
Year: 2007

description: Model-driven architecture  aims at describing a system using a platform-independent model in sufficient detail so that the full implementation of the system can be generated from this model and a platform model. This implies that the platform-independent model must  describe the static structure as well as the dynamic behavior of the system.
We propose a declarative language for describing the behavior of platform-independent models based on a hybrid notation that uses graphical elements as well as textual elements in the form of OCL code snippets. Compared to existing approaches based on action languages  it is situated at a higher level of abstraction and, through a clean separation of modifier operations and query operations, simplifies the comprehension of the behavioral aspects of the platform-independent system.

description: When a rod is vertically withdrawn from a granular layer, oblique force chains can be developed by effective shearing. In this study, the force-chain structure in a rod-withdrawn granular layer was experimentally investigated using a photoelastic technique. The rod is vertically withdrawn from a two-dimensional granular layer consisting of bidisperse photoelastic disks. During the withdrawal, the development process of force chains is visualized by the photoelastic effect. By systematic analysis of photoelastic images, force chain structures newly developed by the rod withdrawing are identified and analyzed. In particular, the relation between the rod-withdrawing force $F_\mathrm{w}$, total force-chains force $F_\mathrm{t}$, and their average orientation $θ$ are discussed. We find that the oblique force chains are newly developed by withdrawing. The force-chain angle $θ$ is almost constant (approximately $20^{\circ}$ from the horizontal), and the total force $F_\mathrm{t}$ gradually increases by the withdrawal. In addition, $F_\mathrm{t}\sinθ$ shows a clear correlation with $F_\mathrm{w}$.

description: Double-level quantum systems are good candidates for revealing coherent quantum transport properties. Here, we consider quantum interference effects due to the formation of a two-level system (TLS) coupled to the edge channel of a zigzag Phosphorene nanoribbon (ZPNR). Using the tight-binding approach, we first demonstrate the formation of a TLS in bulk Phosphorene sheet due to the existence of two nearby vacancy impurities. Then, we show that such a TLS can couple to the quasi-one-dimensional continuum of the edge states in a ZPNR which results in the the appearance of two-dip Fano-type line shapes. To this end, we generalize the Lippmann-Schwinger approach to study the scattering of edge electrons in a ZPNR by two coupled impurity defects. We obtain an analytical expression of the transmission coefficient which shows that the positions and widths of the anti-resonances can be controlled by changing the intervacancy distance as well as their distance from the edge of the ribbon. This work constitutes a clear example of the multiple Fano resonances in mesoscopic transport.

description: OCL is used to add rigour to UML/MOF models, and in
particular can be used to express behavioural details (e.g.,
operation pre- and postconditions, class invariants) of such models.
The applicability and utility of OCL can be assessed by applying it
to realistic applications and by investigating its capabilities both
in terms of language characteristics and tool support. With this in
mind, in this paper we model functional requirements for the Mondex Smart Card Application using UML Diagrams, demonstrate how system invariants as well as operation pre- and post-conditions are specified in OCL, and explore the degree to which OCL tool  support can be used to create and validate these models. Moreover, we discuss how these pre- and post-conditions can be validated, in part by discussing how test cases can be selected from the OCL specifications created.

The maintenance of gynodioecy in sidalcea hendersonii
Creators: name: Marshall, Melanie
Publisher: name: University of British Columbia
Year: 2009

description: I investigated the genetic and ecological factors contributing to the maintenance of females in populations of the gynodioecious plant, Sidalcea hendersonii. Crossing experiments indicated that male sterility is controlled by a dominant nuclear allele. High frequencies of female plants in the majority of populations surveyed, in combination with nuclear determination of sex, elevates the theoretical requirements for female fitness in this species. Females did have higher fitness, producing more surviving offspring than hermaphrodite plants in an experimental population, and outcrossed hermaphrodite plants out-performed self-pollinated hermaphrodites. These results suggest that female advantage is the product of both maternal effect and obligate outcrossing. However, no inherent fitness advantages were evident in natural populations where females and hermaphrodites did not differ in viable seed production. Ecological factors may play an important role in the maintenance of gynodioecy. Though flower size differences between the sexes (thought to be related to pollinator visitation) did not affect seed production, seed predation did. In populations where females were abundant, weevil larvae destroyed significantly more seeds from hermaphrodite plants and substantially reduced hermaphrodite seed production overall. This study provides the first evidence that sex-related predation may be responsible for high female frequencies in natural populations of a gynodioecious species.

description: We study the electromagnetic response of a chiral ${\rm d_{xy}+id_{x^2-y^2}}$ charge density wave state. Due to parity (${\cal P}$) and time reversal (${\cal T}$) violation, Chern-Simons terms emerge in the effective action of the U(1) gauge field. As a consequence electric and magnetic fields are coupled providing the possibility of observing the Spontaneous Quantum Hall Effect i.e. generation of Hall voltage via the sole application of an electric field. We show how the Chern-Simons terms are induced and discuss the topological origin of the quantization of Hall conductance.

description: The utilization of barium sulfate (BaSO4) as a cost-effective reflectance standard has been well-documented over time. When in its pure salt form, its optical characteristics offer distinct advantages compared to laboratory-grade sintered polytetrafluoroethylene (PTFE). Despite this, the practical application of BaSO4 doesn't significantly outshine the stability of PTFE.This paper delves into the process of creating pelletized BaSO4 and delves into the characterization of its optical reflectance properties. The analysis of data concerning its sintered form reveals that BaSO4 stands out as an impressive, budget-friendly material offering both high reflectivity and remarkable consistency. Even in its current sintered state, which might be considered rudimentary, BaSO4 exhibits a reasonably stable texture, capable of withstanding minor mechanical stress. Its reflectivity across the UV-VIS-NIR range (173–2500 nm) averages at an impressive 92%, notably surpassing that of a PTFE reflection standard.

description: The Petrov solution (for $Λ=0$) and the Kaigorodov-Ozsváth solution (for $Λ<0$) provide examples of vacuum solutions of the Einstein equations with simply-transitive isometry groups. We calculate the boundary stress-tensor for the Kaigorodov-Ozsváth solution in the context of the adS/CFT correspondence. By giving a matrix representation of the Killing algebra of the Petrov solution, we determine left-invariant one-forms on the group. The algebra is shown to admit a two-parameter family of linear deformations a special case of which gives the algebra of the Kaigorodov-Ozsváth solution. By applying the method of non-linear realisations to both algebras, we obtain a Lagrangian of Finsler type from the general first-order action in both cases. Interpreting the Petrov solution as the exterior solution of a rigidly rotating dust cylinder, we discuss the question of creation of CTCs by spinning up such a cylinder. We show geodesic completeness of the Petrov and Kaigorodov-Ozsváth solutions and determine the behaviour of geodesics in these spacetimes. The holonomy groups were shown to be given by the Lorentz group in both cases.

description: The nature of the "forbidden" local- and long-range polar order in nominally nonpolar paraelectric phases of ferroelectric materials has been an open question since the discovery of ferroelectricity in oxide perovskites (ABO3). A currently considered model suggests locally correlated displacements of B-site atoms along a subset of <111> cubic directions. Such offsite displacements have been confirmed experimentally, however, being essentially dynamic in nature they cannot account for the static nature of the symmetry-forbidden polarization implied by the macroscopic experiments. Here, in an atomically resolved study by aberration corrected scanning transmission electron microscopy (STEM) complemented by Raman spectroscopy, we reveal, directly visualize and quantitatively describe static, 2-4 nm large polar nanoclusters in the nominally nonpolar cubic phases of (Ba,Sr)TiO3 and BaTiO3. These results have implications on understanding of the atomic-scale structure of disordered materials, the origin of precursor states in ferroelectrics, and may help answering ambiguities on the dynamic-versus-static nature of nano-sized clusters.

description: A powerful new impurity solver is shown to permit a systematic study of the doping driven Mott transition in a one-band Hubbard model within the framework of single-site dynamical mean field theory. At small dopings and large interaction strengths we are able access low enough temperatures that a reliable extrapolation to temperature T=0 may be performed, and ground state energies of insulating and metallic states may be compared. We find that the T=0 doping-driven transition is of second order and is characterized by an interaction-strength dependent electronic compressibility, which vanishes at the critical interaction strength of the half filled model. Over wide parameter ranges the compressibility is substantially reduced relative to the non-interacting system. The metal insulator transition is characterized by the appearance of in-gap states, but these are relevant only for very low dopings of less than 3%.

description: We calculate the steady-state and first-order time varying atom-field correlation functions in the weak-excitation limit of absorptive optical bistability from a linearized theory of quantum fluctuations. We formulate a Fokker-Planck equation in the positive P representation following the phase-space analysis of [H. J. Carmichael, Phys. Rev. A 33, 3262 (1986)] which is suitable for the determination of cross-correlations as it does not resort to adiabatic elimination. Special emphasis is placed on the limit of collective strong coupling as attained from a vanishing photon-loss rate. We compare to the cavity-transmission spectrum with reference to experimental results obtained for macroscopic dissipative systems, discussing the role of anomalous correlations arising as distinct nonclassical features.

description: Evidence for broken time reversal symmetry (TRS) has been found in the superconducting states of the $R_5$Rh$_6$Sn$_{18}$ (R = Sc, Y, Lu) compounds with a centrosymmetric caged crystal structure, but the origin of this phenomenon is unresolved. Here we report neutron diffraction measurements of single crystals with $R$=Lu, as well as measurements of the temperature dependence of the magnetic penetration depth using a self-induced tunnel diode-oscillator (TDO) based technique, together with band structure calculations using density functional theory. Neutron diffraction measurements reveal that the system crystallizes in a tetragonal caged structure, and that one of nominal Lu sites in the Lu$_5$Rh$_6$Sn$_{18}$ structure is occupied by Sn, yielding a composition Lu$_{5-x}$Rh$_6$Sn$_{18+x}$ ($x=1$). The low temperature penetration depth shift $Δλ(T)$ exhibits an exponential temperature dependence below around $0.3T_c$, giving clear evidence for fully gapped superconductivity. The derived superfluid density is reasonably well accounted for by a single gap $s$-wave model, whereas agreement cannot be found for models of TRS breaking states with two-component order parameters. Moreover, band structure calculations reveal multiple bands crossing the Fermi level, and indicate that the aforementioned TRS breaking states would be expected to have nodes on the Fermi surface, in constrast to the observations.

description: A systematic literature review (SLR) is a methodology used to find and aggregate all relevant existing evidence about a specific research question of interest. Important decisions need to be made at several points in the review process, relating to search of the literature, selection of relevant primary studies and use of methods of synthesis. Visualization can support tasks that involve large collections of data, such as the studies collected, evaluated and summarized in an SLR. The objective of this paper is to present the results of a systematic mapping study (SM) conducted to collect and evaluate evidence on the use of a specific visualization technique, visual data mining (VDM), to support the SLR process. We reviewed 20 papers and our results indicate a scarcity of research on the use of VDM to help with conducting SLRs in the software engineering domain. However, most of the studies (16 of the 20 studies included in our mapping) have been conducted in the field of medicine and they revealed that the activities of data extraction and data synthesis, related to conducting the review phase of an SLR process, have more VDM support than other activities. In contrast, according to our SM, previous studies using VDM techniques with SLRs have not employed such techniques during the SLR's planning and reporting phases.

description: Henriques and Kamnitzer have defined a commutor for the category of crystals of a finite-dimensional complex reductive Lie algebra that gives it the structure of a coboundary category (somewhat analogous to a braided monoidal category). Kamnitzer and Tingley then gave an alternative definition of the crystal commutor, using Kashiwara's involution on Verma crystals, that generalizes to the setting of symmetrizable Kac-Moody algebras. In the current paper, we give a geometric interpretation of the crystal commutor using quiver varieties. Equipped with this interpretation we show that the commutor endows the category of crystals of a symmetrizable Kac-Moody algebra with the structure of a coboundary category, answering in the affirmative a question of Kamnitzer and Tingley.

description: In order to test the O star wind-shock scenario for X-ray production in less luminous stars with weaker winds, we made a pointed 74 ks observation of the nearby early B giant, beta Cru (B0.5 III), with the Chandra HETGS. We find that the X-ray spectrum is quite soft, with a dominant thermal component near 3 million K, and that the emission lines are resolved but quite narrow, with half-widths of 150 km/s. The forbidden-to-intercombination line ratios of Ne IX and Mg XI indicate that the hot plasma is distributed in the wind, rather than confined near the photosphere. It is difficult to understand the X-ray data in the context of the standard wind-shock paradigm for OB stars, primarily because of the narrow lines, but also because of the high X-ray production efficiency. A scenario in which the bulk of the outer wind is shock heated is broadly consistent with the data, but not very well motivated theoretically. It is possible that magnetic channeling could explain the X-ray properties, although no field has been detected on beta Cru. We detected periodic variability in the hard (hnu > 1 keV) X-rays, modulated on the known optical period of 4.58 hours, which is the period of the primary beta Cep pulsation mode for this star. We also have detected, for the first time, an apparent companion to beta Cru at a projected separation of 4 arcsec. This companion was likely never seen in optical images because of the presumed very high contrast between it and beta Cru in the optical. However, the brightness contrast in the X-ray is only 3:1, which is consistent with the companion being an X-ray active low-mass pre-main-sequence star. The companion's X-ray spectrum is relatively hard and variable, as would be expected from a post T Tauri star.

Reformulation of Boundary String Field Theory in terms of Boundary State
Creators: name: Teraguchi, Shunsuke
Publisher: name: arXiv
Year: 2006
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We reformulate bosonic boundary string field theory in terms of boundary state. In our formulation, we can formally perform the integration of target space equations of motion for arbitrary field configurations without assuming decoupling of matter and ghost. Thus, we obtain the general form of the action of bosonic boundary string field theory. This formulation may help us to understand possible interactions between boundary string field theory and the closed string sector.

description: Sparticle mass hierarchies will play an important role in the type of signatures that will be visible at the Large Hadron Collider. We analyze these hierarchies for the four lightest sparticles for a general class of supergravity unified models including nonuniversalities in the soft breaking sector. It is shown that out of nearly $10^4$ possibilities of sparticle mass hierarchies, only a small number survives the rigorous constraints of radiative electroweak symmetry breaking, relic density and other experimental constraints. The signature space of these mass patterns at the Large Hadron Collider is investigated using a large set of final states including multi-leptonic states, hadronically decaying $τ$s, tagged $b$ jets and other hadronic jets. In all, we analyze more than 40 such lepton plus jet and missing energy signatures along with several kinematical signatures such as missing transverse momentum, effective mass, and invariant mass distributions of final state observables. It is shown that a composite analysis can produce significant discrimination among sparticle mass patterns allowing for a possible identification of the source of soft breaking. While the analysis given is for supergravity models, the techniques based on mass pattern analysis are applicable to wide class of models including string and brane models.

C# 3.0 makes OCL redundant!

description: Other than its "platform independence" the major advantages of OCL over traditional Object Oriented programming languages has been the declarative nature of the language, its powerful navigation facility via the iteration operations, and the availability of tuples as a first class concept. The recent offering from Microsoft of the "Orcas" version of Visual Studio with C# 3.0 and the Linq library provides functionality almost identical to that of OCL. This paper examines and evaluates the controversial thesis that, as a result of C# 3.0, OCL is essentially redundant, having been superseded by the incorporation of its advantageous features into a mainstream programming language.

Year: 2007

description: Executable UML allows precisely describing the software system at a higher level of abstraction. The executable models can be translated to a less abstract program-ming language completely or executed directly. Object Constraint Language (OCL), as a formal specification language, is a standard published along with UML. It is primitively used to describe constraints for UML models. In this paper, we explore some general features of executable UML and propose using OCL in executable UML. We extend OCL to support actions with side-effect in order to precisely model behavior. We also discuss the some open issues.

Publisher: name: Zenodo
Year: 2019
Subjects: Wind farm control

description: CL-Windcon is the first EU Wind Energy research project 100% control oriented. This project is focused on wind farm flow control, in both open and closed loop, as a need from the control perspective. Wind farm control problem, as any other control problem, is a multidisciplinary exercise, which is clearly shown in the CL-Windcon project. Then, the control common activities are present in the project: multi-fidelity models development and analysis, theoretical scenarios to focus while developing and comparing results with and without control. Of course, the core work for this project is focused on the control algorithm development. Mainly open and closed loop algorithms for wind farm flow control, but also the control algorithms at wind turbine level, needed to support the wind farm flow control as well as other ancillary services that can be provided to the network. This project also combines an important set of validation activities, which will be mostly open access, in multi-fidelity simulations, wind tunnel tests, and a field test campaign. Other feasibility activities are also performed in the project, which among other things covers maintenance impact, LCA, standards review.
Extended OCL for Goal Monitoring
Creators: name: Robinson, William
Publisher: name: European Association of Software Science and Technology
Year: 2007

description: Monitoring human-computer interaction aids the analysis for understanding how well software meets its purpose.  In particular, monitoring human-computer interactions with respect to a user's goal model helps to determine user satisfaction.  By formalizing a goal model, runtime monitors can be automatically derived.

The REQMON system monitors the satisfaction of goal models.  Recently, an OCL compiler was developed for REQMON.  The OCL was extended slightly to address temporal and real-time constraints.  Now, goal models can be represented in the extended OCL, from which runtime monitors can be compiled.  The resulting REQMON system appears to be easier to use comes the abstract.

Le théâtre de l’absurde québécois

description: Les années cinquante ont vu l'apparition d'un «théâtre d'avant-garde» en France, sous la plume d'auteurs tels que Samuel Beckett, Eugene Ionesco, Jean Genet et Arthur Adamov. Au Québec, le même phénomène s'est produit, mais l'étiquette officielle de «théâtre de l'absurde québécois» n'a pas encore été prêtée à un corpus défini de pièces de théâtre. Cette étude, dans un premier temps, effectue un repérage des caractéristiques intrinsèques aux oeuvres du théâtre de l'absurde français, plus précisément celles des quatre auteurs mentionnes ci-dessus, a l'aide d'ouvrages théoriques reconnus (notamment The Theatre of the Absurd de Martin Esslin, Histoire du «nouveau théâtre» de Geneviève Serreau, Le Théâtre du nouveau langage de Gilbert Tarrab et Le théâtre de dérision d'Emmanuel Jacquart). Les chapitres subséquents sont consacrés a 1'analyse des oeuvres dramatiques québécoises Les Insolites de Jacques Languirand et La répétition de Dominic Champagne, afin de vérifier l'occurence des mêmes traits, particuliers au théâtre de dérision, et de montrer l'existence réelle de ce type de théâtre au Québec.
Analyzing Semantic Properties of OCL Operations by Uncovering Interoperational Relationships

description: The OCL (Object Constraint Language) as part of the UML (Unified Modeling Language) is a rich language with different collection kinds (sets, multi-sets, sequences) and a large variety of operations defined thereon. Without negating the strong correlation between both fields we can say that these operations have their origin partly in logic (like the operations forAll and exists) and partly in computer science, in particular database systems (like the operation select). Some of these operations may be expressed in terms of other operations. This paper presents a systematic study of relationships which hold between OCL features like the mentioned operations. Apart from presenting the relationships between operations in a conceptual way, the relationships are described by a formal metamodel allowing systematic and computer supported access to the operation relationships by querying an underlying formal description.

Faster Exact Exchange in Periodic Systems using Single-precision Arithmetic
Creators: name: Vinson, John
Publisher: name: arXiv
Year: 2020
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: Density-functional theory simplifies many-electron calculations by approximating the exchange and correlation interactions with a one-electron operator that is a functional of the density. Hybrid functionals incorporate some amount of exact exchange, improving agreement with measured electronic and structural properties. However, calculations with hybrid functionals require substantial computational resources, limiting their use. By calculating the exchange interaction of periodic systems with single-precision arithmetic, the computation time is cut nearly in half with a negligible loss in accuracy. This improvement makes exact exchange calculations quicker and more feasible, especially for high-throughput calculations. Example hybrid density-functional theory calculations of band energies, forces, and x-ray absorption spectra show that this single-precision implementation maintains accuracy with significantly reduced runtime and memory requirements.

description: A quantitative method is suggested, where meanings of words, and grammatic rules about these, of a vocabulary are represented by real numbers. People meet randomly, and average their vocabularies if they are equal; otherwise they either copy from higher hierarchy or stay idle. Presence of teachers broadcasting the same (but arbitrarily chosen) vocabulary leads the language formations to converge more quickly.

description: Palladium (Pd) is well-known for its role in catalyzing hydrogen-based reduction reactions, owing to its excellent catalytic activity and hydrogen storage ability. Its surface and subsurface structures under electrochemical conditions are vital in understanding the hydrogen evolution reaction (HER) mechanism at the Pd cathodes where the most active sites are located on ‘in situ’ formed Pd-hydride layers. In this work, we investigate the process of Pd-hydride formation as well as the step-by-step formation and stability of Pd-hydride/Pd interfaces under electrochemical conditions using first-principles calculations. Our results reveal that among the low-indexed surfaces (111), (110) and (100), the (111) surface is expected to be the most dominant surface in a Pd nanostructure in addition to being the most preferred surface for hydrogen adsorption. Based on calculated Pourbaix diagrams, we can identify the relevant regions close to the equilibrium electrode potential and pH for proton electroreduction and hydrogen evolution, where the Pd surfaces start to be covered by hydrogen adatoms, and when the electrode potential is decreased, there are clear thermodynamic indications for more and more subsurface hydride layers. Overall, the results provide insights into the stability and formation of hydrogen containing Pd surfaces, forming PdH/Pd type interfaces. Our idealized model systems are a first step towards elucidation of relevant active sites on Pd.
