Epidemiology and Biological Consequences of Outer Membrane Protein Phase Variation in Neisseria meningitidis

description: Serogroup W, clonal complex 11 Neisseria meningitidis (the ‘meningococcus’) are a major cause of morbidity and mortality worldwide. The mechanisms underpinning the success of this clone remain unclear but are likely to include the expression of adhesins. Meningococci express Opa proteins, which mediate adhesion to/invasion of host cells. Opa expression undergoes phase variation – a high frequency ON/OFF switch in gene expression due to insertion/deletions of pentameric repeats (5’ CTCTT) in the coding region. An additional protein, NadA, functions as an adhesin and is phase-variable through tetrameric repeats (5’ TAAA) in an upstream regulatory region. Comparative studies using whole genome sequence analysis and gene fragment size analysis on 121 disease and 54 carriage MenW:cc11 strains was conducted to determine whether expression patterns for Opa proteins are similar for disease and carriage isolates. Subsequently, inactivating mutations were constructed in the opa, pilE and nadA genes of three MenW:cc11 isolates. These mutants were tested in in vitro infection assays for adhesion and invasion of A549 and Calu-3 epithelial cells. Repeat number and allele variability were detected between the ‘original UK’ strain and the novel ‘2013 strain’ of the MenW:cc11 lineage. Conversely no significant differences in the patterns of Opa protein expression were observed between disease and carriage isolates, with OpaA expression being switched ON in the majority of isolates. The outputs of adhesion and invasion assays suggested that pilE and nadA have an effect on adhesion and invasion respectively. Permeability assays show that there is a significant reduction in disruption of the epithelial monolayer in the absence of pilE. and NadA whereas Opa mutants cause the same amount of disruption as the wildtype. Our findings indicate that the Opa proteins do not contribute to the invasiveness of MenW:cc11 strains but may have contributed to the evolution of the lineage possibly by enhancing phase variation-mediated immune evasion.

description: The novel coronavirus SARS-CoV-2 and the COVID-19 illness it causes have inspired unprecedented levels of multidisciplinary research in an effort to address a generational public health challenge. In this work we conduct a scientometric analysis of COVID-19 research, paying particular attention to the nature of collaboration that this pandemic has fostered among different disciplines. Increased multidisciplinary collaboration has been shown to produce greater scientific impact, albeit with higher co-ordination costs. As such, we consider a collection of over 166,000 COVID-19-related articles to assess the scale and diversity of collaboration in COVID-19 research, which we compare to non-COVID-19 controls before and during the pandemic. We show that COVID-19 research teams are not only significantly smaller than their non-COVID-19 counterparts, but they are also more diverse. Furthermore, we find that COVID-19 research has increased the multidisciplinarity of authors across most scientific fields of study, indicating that COVID-19 has helped to remove some of the barriers that usually exist between disparate disciplines. Finally, we highlight a number of interesting areas of multidisciplinary research during COVID-19, and propose methodologies for visualising the nature of multidisciplinary collaboration, which may have application beyond this pandemic.

description: We introduce a new spinfoam vertex to be used in models of 4d quantum gravity based on SU(2) and SO(4) BF theory plus constraints. It can be seen as the conventional vertex of SU(2) BF theory, the 15j symbol, in a particular basis constructed using SU(2) coherent states. This basis makes the geometric interpretation of the variables transparent: they are the vectors normal to the triangles within each tetrahedron. We study the condition under which these states can be considered semiclassical, and we show that the semiclassical ones dominate the evaluation of quantum correlations. Finally, we describe how the constraints reducing BF to gravity can be directly written in terms of the new variables, and how the semiclassicality of the states might improve understanding the correct way to implement the constraints.

description: This article discusses the problem of estimation of parameters in finite mixtures when the mixture components are assumed to be symmetric and to come from the same location family. We refer to these mixtures as semi-parametric because no additional assumptions other than symmetry are made regarding the parametric form of the component distributions. Because the class of symmetric distributions is so broad, identifiability of parameters is a major issue in these mixtures. We develop a notion of identifiability of finite mixture models, which we call k-identifiability, where k denotes the number of components in the mixture. We give sufficient conditions for k-identifiability of location mixtures of symmetric components when k=2 or 3. We propose a novel distance-based method for estimating the (location and mixing) parameters from a k-identifiable model and establish the strong consistency and asymptotic normality of the estimator. In the specific case of L_2-distance, we show that our estimator generalizes the Hodges--Lehmann estimator. We discuss the numerical implementation of these procedures, along with an empirical estimate of the component distribution, in the two-component case. In comparisons with maximum likelihood estimation assuming normal components, our method produces somewhat higher standard error estimates in the case where the components are truly normal, but dramatically outperforms the normal method when the components are heavy-tailed.

description: 20. yüzyılda demiryolu ulaşımının diğer ulaşım seçeneklerinin gerisinde kalmasıyla birçok gar işlevini yitirmiştir. Ancak yüksek hızlı trenlerin yaygınlaşmasıyla demiryolu ulaşımı tekrar önemli bir seçenek haline gelmiş ve tren garları da yeni bir canlanma çağına girmiştir. Pek çok ülkede yüksek hızlı trenlere hizmet edebilecek garlar inşa edilmeye başlanmıştır. Yaşanan bu teknolojik gelişmelerden dolayı yakın gelecekte sayılarının artacağı düşünülen demiryolu ulaşımının en önemli unsurlarından olan garların tasarımı da, mimarlık ve mühendislik açısından değişime uğramaktadır. Tren garları ulaşımın ötesinde çok fonksiyonlu bir yapıya bürünmekte ve bu fonksiyonlar çok farklı tasarım ve yapım problemini beraberinde getirmektedir. Türkiye Bina Deprem Yönetmeliğine (TBDY, 2018) göre önem derecesi en yüksek yapı grubu (BKS=1) içinde olan tren garlarının ulaşımın, ticari ve sosyal faaliyetlerin kesintiye uğramaması için güvenli birer yapı olarak tasarlanmaları oldukça önemlidir. Tren garlarında, yatay yük altındaki yapısal davranış mekânsal örgütlenme ve biçimle değiştiği için yeterli deprem dayanımının sağlanmasında mimarlara büyük sorumluluk düşmektedir. Oluşabilecek zararların önüne geçilebilmesi için garların işlevsellikle beraber taşıyıcı sistem bilgisiyle tasarlanarak depreme dayanıklı yapısal form ve malzeme seçimiyle tamamlanması, deprem faktörünün mimari tasarım kriteri olarak ele alınması gerekmektedir. Yapılan bu çalışmada ülkemizdeki aktif fay hatları üzerinde tasarlanan 4 adet tren garının taşıyıcı sistem kararları, fonksiyonel organizasyona bağlı mekanları, plan tipleri, strüktür ve yapı malzemeleri veri toplama analizi yöntemiyle değerlendirilmiştir. Örneklerin taşıyıcı sistemleri, TBDY’de bulunan planda ve düşeyde düzensizlik durumlarına göre gözlemsel olarak analiz edilmiş ve depremin tasarım kriteri olarak kabul edilip edilmediği incelenmiştir. Sonuç olarak mimari tasarımın çoğunlukla düzensizlik durumlarına dikkat edilerek kurgulandığı, deprem davranışını olumsuz yönde etkileyebilecek önemli tasarım hatalarının olmadığı görülmüştür. Bu açıdan mimarlık disiplininin kendi sorumluluğunu depreme dayanıklı yapı tasarımı açısından özümsediği anlaşılmaktadır.

description: A bargaining game is investigated for cooperative energy management in microgrids. This game incorporates a fully distributed and realistic cooperative power scheduling algorithm (CoDES) as well as a distributed Nash Bargaining Solution (NBS)-based method of allocating the overall power bill resulting from CoDES. A novel weather-based stochastic renewable generation (RG) prediction method is incorporated in the power scheduling. We demonstrate the proposed game using a 4-user grid-connected microgrid model with diverse user demands, storage, and RG profiles and examine the effect of weather prediction on day-ahead power scheduling and cost/profit allocation. Finally, the impact of users' ambivalence about cooperation and /or dishonesty on the bargaining outcome is investigated, and it is shown that the proposed game is resilient to malicious users' attempts to avoid payment of their fair share of the overall bill.

description: Pure Yang-Mills theory on ${\mathbb R} \times S^2$ is analyzed in a gauge-invariant Hamiltonian formalism. Using a suitable coordinatization for the sphere and a gauge-invariant matrix parametrization for the gauge potentials, we develop the Hamiltonian formalism in a manner that closely parallels previous analysis on ${\mathbb R}^3$. The volume measure on the physical configuration space of the gauge theory, the nonperturbative mass-gap and the leading term of the vacuum wave functional are discussed using a point-splitting regularization. All the results carry over smoothly to known results on ${\mathbb R}^3$ in the limit in which the sphere is de-compactified to a plane.

description: The detection and quantification of quantum coherence play significant roles in quantum information processing. We present an efficient way of tomographic witnessing for both theoretical and experimental detection of coherence. We prove that a coherence witness is optimal if and only if all of its diagonal elements are zero. Naturally, we obtain a bona fide homographic measure of coherence given by the sum of the absolute values of the real and the imaginary parts of the non-diagonal entries of a density matrix, together with its interesting relations with other coherence measures like $l_1$ norm coherence and robust of coherence.

description: The antiferromagnetic Ising model in small-world networks generated from two-dimensional regular lattices has been studied. The disorder introduced by long-range connections causes frustration, which gives rise to a spin-glass phase at low temperature. Monte Carlo simulations have been carried out to study the paramagnetic to spin-glass transition, as a function of the rewiring probability p, which measures the disorder strength. The transition temperature Tc goes down for increasing disorder, and saturates to a value Tc ~ 1.7 J for p > 0.4, J being the antiferromagnetic coupling. For small p and at low temperature, the energy increases linearly with p. In the strong-disorder limit p=1, this model is equivalent to a short-range +-J spin glass in random networks.

description: The work reported below is a first of its kind study of the properties of turbulent flow without strong mean shear in a Newtonian fluid in proximity of the turbulent/non-turbulent interface, with emphasis on the small scale aspects. The main tools used are a three-dimensional particle tracking system (3D-PTV) allowing to measure and follow in a Lagrangian manner the field of velocity derivatives and direct numerical simulations (DNS). The comparison of flow properties in the turbulent (A), intermediate (B) and non-turbulent (C) regions in the proximity of the interface allows for direct observation of the key physical processes underlying the entrainment phenomenon. The differences between small scale strain and enstrophy are striking and point to the definite scenario of turbulent entrainment via the viscous forces originating in strain.

Structural geology of part of the Crooked Lake area, Quesnel Highlands, British Columbia
Creators: name: Carye, Jeffrey Alyn
Publisher: name: University of British Columbia
Year: 2010

description: The Crooked Lake area, which lies at the boundary of the Omineca Crystalline Belt and the Intermontane Belt of the Canadian Cordillera, has been examined with close attention being paid to the detailed structural relations of the five lithologies that comprise this map area - the late Proterozoic Snowshoe Formation, the late Paleozoic Antler Formation, Upper Triassic to Lower Jurassic phyllites and phyllitic siltstones and a unit of micaceous quartzite, herein named the Crooked Lake Phyllite and the Eureka Quartzite, respectively, and the Upper Triassio to Lower Jurassic Takla Group. These units form a normal stratigraphic succession with respect to each other, though given data suggests far more complicated internal relations for each of the five units. The major contacts, where exposed, were seen to be continuous with internal foliation fabrics, sharply planar (to somewhat gradational in the case of the Takla base), and occasionally associated with mylonitic fabrics. These surfaces may represent faults, though sufficient data is not available for estimates of displacement magnitude and/or direction to be given. Structural features used to develop a relative timing sequence for internal progressive deformation of the Crooked Lake rock units include bedding surfaces and compositional layerings, foliations and cleavages, crenulations and other linear structures, minor fold forms and fold interference patterns, and fracture sets. The five distinct sets of deformation features that represent this timing sequence are the following: isoclinal, intrafolial, rootless folds of compositional layering found exclusively in the Snowshoe and Antler Formations (D1), open to tight folds of bedding, compositional layering, earlier foliations, and major contacts and a pervasive mica/amphibole foliation (D2 relative to Snowshoe and Antler), upright open to medium folds of earlier surfaces and major contacts (D3), gentle to open folds and kink folds of pervasive D2 foliation and compositional layering (D4), and northeasterly directed faults and fracture sets (D5). The metamorphic history of the Crooked Lake rock units has been deduced from extensive microscopic examination of textures and mineral assemblages. Barrovian-type metamorphism accompanied the first three deformational episodes; the first event may have reached amphibolite grade, the second episode reached temperatures of 500-575° at pressures of 4-7 kbars (from equilibria of pelitic and mafic assemblages), and the third approached only the lower to middle greenschist grade. Appendices have been included summarizing rock description data, structural data, fold form data, and stereo-photography of prominent structural features.

description: To a compact hyperbolic Riemann surface, we associate a finitely summable spectral triple whose underlying topological space is the limit set of a corresponding Schottky group, and whose ``Riemannian'' aspect (Hilbert space and Dirac operator) encode the boundary action through its Patterson-Sullivan measure. We prove that the ergodic rigidity theorem for this boundary action implies that the zeta functions of the spectral triple suffice to characterize the (anti-)conformal isomorphism class of the corresponding Riemann surface. Thus, you can hear the shape of a Riemann surface, by listening to a suitable spectral triple.

Even within the simple framework of lattice-gas type models, we are able to address several experimentally observed issues including nonmonotonic dependence of the degree of order on annealing temperature, and the rapid decrease of order upon overdoping with either B or B' species. We also study ordering in the `ternary' compounds A_2BB'_{1-y}B''_yO_6 Although our emphasis is on the double perovskites, our results are easily generalizable to a wide variety of binary and ternary alloys.

A Case Analysis of the Bungkalan Practice in an Upland Community From the Perspective of Agroecology Movement
Creators: name: Alonzo, Lia Mai
Publisher: name: Zenodo
Year: 2023

description: The farmers have the highest poverty incidence among all sectors in the Philippines. They have also been greatly affected be the COVID-19 pandemic. However, the farmers of Lupang Ramos in Dasmariñas City, Cavite were able to get through the two years under the pandemic with enough food supply for their community. They point to agroecology as a social movement as the key factor. However, their community is still facing a decades-old land dispute which has threatened their access to land where they live and farm. The study therefore aims to analyze how the farmers in Lupang Ramos used agroecology to address the issues faced by their community. Particularly, it aims to describe issues on land tenure and food production, and the current agroecology practices being used by the local organization in the bungkalan (communal farm system) to bring about positive change while focusing on agroecology as a social movement. The study was a descriptive research, particularly a case study, which gathered data using key informant interviews and documents review. The results showed that the farmers are still facing threats of eviction with the distribution of Certificate of Land Ownership Awards still and the National Grid Corporation Project still pending. Also, there were three aspects of agroecology as a social movement that was harnessed by the farmers through the bungkalan campaign of their organization Katipunan ng mga Lehitimong Magsasaka at Mamamayan sa Lupang Ramos (KASAMA-LR), the transformation of dominant agricultural systems through organic farming, focus on food producers issues and rights through legal and other forms of mobilizations to assert their right to land and farm inputs, and collective action through the mobilization of their community and external organizations and institutions. With this, it can be concluded that the bungkalan campaign embodied agroecology as a social movement which resulted in the increase of food production and access to land. It is recommended that a quantitative study on the improvement of food production after the bungkalan be conducted as well as the other aspects of agroecology to deepen the understanding of this field and help improve the situation of other farmers.

description: This research, through a case study, examined the work of “pure” researchers, who only performed research as their tasks without teaching at Vietnam’s higher education institutions, as well as the influence of institutional elements of their organization on their attachment to the workplace. Through the use of the theoretical framework that Scott proposes, the three pillars of institutions, this study revealed that the participants in this study worked at an organization with almost no specific rules for researchers, nor effective policies on developing those staff members. Expectations for researchers were also not clear and individually determined. Researchers had to undertake many different tasks that they thought were unimportant to the organization’s mission, obligatory, monotonous, or beyond their ability. All three pillars in the institutional life of the organization had an impact on the participants’ attachment to the institute, and enhancing the aspect of research required changes to some institutional elements.

description: A complete thermodynamical analysis of the 2+1 dimensional massless Gross-Neveu model is performed using the optimized perturbation theory. This is a non-perturbative method that allows us to go beyond the known large-N results already at lowest order. Our results, for a finite number of fermion species, N, show the existence of a tricritical point in the temperature and chemical potential phase diagram for discrete chiral phase transition allowing us to precisely to locate it. By studying the phase diagram in the pressure and inverse density plane, we also show the existence of a liquid-gas phase, which, so far, was unknown to exist in this model. Finally, we also derive N dependent analytical expressions for the fermionic mass, critical temperature and critical chemical potential.

description: We compute the dynamical spin structure factor $S(k,ω)$ of the SU(3) Heisenberg chain variationally using a truncated Hilbert space spanned by the Gutzwiller projected particle-hole excitations of the Fermi sea, introduced in [B. Dalla Piazza et al., Nature Physics 11, 62 (2015)], with a modified importance sampling. We check the reliability of the method by comparing the $S(k,ω)$ to exact diagonalization results for 18 sites and to the two-soliton continuum of the Bethe Ansatz for 72 sites. We get an excellent agreement in both cases. Detailed analysis of the finite-size effects shows that the method captures the critical Wess-Zumino-Witten SU(3)$_1$ behavior and reproduces the correct exponent, with the exception of the size dependence of the weight of the bottom of the conformal tower. We also calculate the single-mode approximation for the SU($N$) Heisenberg model and determine the velocity of excitations. Finally, we apply the method to the SU(3) Haldane-Shastry model and find that the variational method gives the exact wave function for the lowest excitation at $k=\pm 2π/3$.

description: The globular cluster (GC) nature of the recently catalogued candidate FSR 1767 is established in the present work. It results as the closest GC so far detected in the Galaxy. The nature of this object is investigated by means of 2MASS colour-magnitude diagrams (CMDs), the stellar radial density profile (RDP) and proper-motions (PM). The properties are consistent with an intermediate metallicity ($\feh\approx-1.2$) GC with a well-defined turnoff (TO), red-giant branch (RGB) and blue horizontal-branch (HB). The distance of FSR 1767 from the Sun is $\ds\approx1.5$ kpc, and it is located at the Galactocentric distance $\rgc\approx5.7$ kpc. With the space velocity components $(V,W)=(184\pm14,-43\pm14)\rm km s^{-1}$, FSR 1767 appears to be a Palomar-like GC with $\mv\approx-4.7$, that currently lies $\approx57$ pc below the Galactic plane. The RDP is well represented by a King profile with the core and tidal radii $\rc=0.24\pm0.08$ pc and $\rt=3.1\pm1.0$ pc, respectively, with a small half-light radius $\rh=0.60\pm0.15$ pc. The optical absorption is moderate for an infrared GC, $A_V=6.2\pm0.3$, which together with its central direction and enhanced contamination explains why it has so far been overlooked.

description: Museums are spaces in which people, culture and collections are woven together. In the 21st century, the museum sector has been encountering demands for transformation, stemming from societal change, contributing to individual and societal well‐being. Of the various contemporary missions, the role of museums and collections in contribution to human rights have come to the fore. The thesis seeks to investigate the public’s right to take part in cultural life enshrined in Article 15(1)(a) of the International Covenant on Economic, Social and Cultural Rights, 1966 (‘ICESCR’), in the context of museums and their collections. The UK and Taiwan are bound to respect, protect and fulfil the right to cultural participation under the ICESCR. On this ground, this thesis engages in comparative legal research to look at legal and ethical guidance provided for the English and Taiwanese museums. It takes a socio‐legal approach to the discussion of Article 15(1)(a) of the ICESCR, the English charity law, museum ethics (including the ethical codes for museums published by ICOM and the Museums Association in the UK), and Taiwanese laws, including the Two Covenants Implementation Act in 2009 and the Cultural Fundamental Act in 2019.
Geology and lithogeochemistry of the cirque stratiform sediment-hosted Ba-Zn-Pb-Ag deposit Northeastern British Columbia
Creators: name: Gorzynski, George Arthur
Publisher: name: University of British Columbia

description: The Cirque deposit is one of several Devono-Mississippian stratiform sediment-hosted Ba-Pb-Zn-Ag deposits in the Akie Zn-Pb district of northeastern British Columbia. It has drill indicated reserves of 32.2 million tonnes grading 7.9% Zn, 2.1% Pb, and 47.7 g/tonne Ag. The "ore" zone is a syngenetic exhalite deposit. Its deposition, however, was but one of many wide-ranging "ore"-related events that dominated sedimentation in the shale basin. These "ore"-related events include exhalative activity, influxes of turbidites and increased organic productivity. Many details of the "ore"-related events can be deduced from field observations and bulk lithogeochemical data. In this study 271 samples representing over 700 m of drillcore were analysed for up to 33 elements. These lithogeochemical data were investigated using a standardization procedure in which analyses were ratioed to the abundances of the relatively immobile detrital components, alumina and zirconium. After this transformation, anomalous abundances of "ore" constituents (Ba, Fe, Zn, Pb, Ag and S) and many other chemical components, were identified in the host rocks beyond the immediate vicinity of the "ore" zone. This procedure also facilitated an estimate of provenance for the host rocks and their relative rates of sedimentation. Geochemical trends are also evident within the "ore" zone. Ba:Sr ratio trends mimic Pb:Zn ratio trends and may be a useful tool in the study and exploration of other stratiform barite deposits. They delineate zoning patterns and may act as a guide to exhalative vent areas which may be of economic interest.

description: We discuss, in the framework of perturbative QCD at next to leading order, two related observables which are usually considered to provide tests of the BFKL dynamics : jet-jet correlations at Tevatron energies and forward particle-jet correlations at HERA. In the first case we study the rapidity gap dependence of the azimuthal correlations and find slightly too strong correlations at large gap. In the second case we discuss the cross section as well as the azimuthal correlations over a rapidity gap range of 5 units. We find that the requirement of a forward particle imposes strong kinematical constraints which distort the distributions, notably at small rapidity gaps. We also show that the decorrelation is stronger in electroproduction than in hadron-hadron collisions. Unfortunately no data are yet available for comparison.

Subjects: Student self-efficacy; study choice; executive-class; marketing approach; graduate program

description: A study related to college major choice has been drawn from many perspectives, including the economic and sociological models, mixed models, and marketing models. However, a study employing the marketing model is still limited. This study aimed to understand the factors influencing student choice in a master's degree in management and business at a private university, specifically at executive class. This study proposed a model and empirically examined the social environment, college-major attributes, and student self-efficacy as an antecedent of college major choices. This study used an explanatory method, undertaken in Indonesia, covering private universities in five provinces in Kalimantan Island, with a sample size of 368 postgraduate students in business. The data analysis employed in this study was SEM-PLS, following an evaluation of the measurement model and structural model to test the hypotheses. The study results indicated that the social environment factor is the most influential factor in encouraging students to enroll in a postgraduate business program. However, the results of the indirect effect showed that college-major attributes are the determining factors in increasing the students' self-efficacy and are considered to have a more significant effect on major choice.

description: The modification of mesonic observables in a hot medium is analyzed as a tool to investigate the restoration of chiral and axial symmetries in the context of the Polyakov-loop extended Nambu--Jona-Lasinio model. The results of the extended model lead to the conclusion that the effects of the Polyakov loop are fundamental for reproducing lattice findings. In particular, the partial restoration of the chiral symmetry is faster in the PNJL model than in the NJL one, and it is responsible for several effects: the meson-quark coupling constants show a remarkable difference in both models, there is a faster tendency to recover the Okubo-Zweig-Iizuka rule, and finally the topological susceptibility nicely reproduces the lattice results around $T/T_c\approx 1.0$.

description: In this paper, genetic programming reinforcement learning (GPRL) is utilized to generate human-interpretable control policies for a Chylla-Haase polymerization reactor. Such continuously stirred tank reactors (CSTRs) with jacket cooling are widely used in the chemical industry, in the production of fine chemicals, pigments, polymers, and medical products. Despite appearing rather simple, controlling CSTRs in real-world applications is quite a challenging problem to tackle. GPRL utilizes already existing data from the reactor and generates fully automatically a set of optimized simplistic control strategies, so-called policies, the domain expert can choose from. Note that these policies are white-box models of low complexity, which makes them easy to validate and implement in the target control system, e.g., SIMATIC PCS 7. However, despite its low complexity the automatically-generated policy yields a high performance in terms of reactor temperature control deviation, which we empirically evaluate on the original reactor template.

description: We introduce a partitioned coupling approach for iterative coupling of flow processes in deformable fractures embedded in a poro-elastic medium that is enhanced by interface quasi-Newton (IQN) methods. In this scope, a unique computational decomposition into a fracture flow and a poro-elastic domain is developed, where communication and numerical coupling of the individual solvers are realized by consulting the open-source library preCICE. The underlying physical problem is introduced by a brief derivation of the governing equations and interface conditions of fracture flow and poro-elastic domain followed by a detailed discussion of the partitioned coupling scheme. We evaluate the proposed implementation and undertake a convergence study to compare a classical interface quasi-Newton inverse least-squares (IQN-ILS) with the more advanced interface quasi-Newton inverse multi-vector Jacobian (IQN-IMVJ) method. These coupling approaches are verified for an academic test case before the generality of the proposed strategy is demonstrated by simulations of two complex fracture networks. In contrast to the development of specific solvers, we promote the simplicity and computational efficiency of the proposed partitioned coupling approach using preCICE and FEniCS for parallel computations of hydro-mechanical processes in complex, three-dimensional fracture networks.
