description: The main purpose of this note is to exhibit a Hamiltonian diffeomorphism loop undetected by the Seidel morphism of certain 2-point blow-ups of $S^2 \times S^2$, exactly one of which being monotone. As side remarks, we show that Seidel's morphism is injective on all Hirzebruch surfaces and discuss how to adapt the monotone example to the Lagrangian setting.

description: Although much research has been conducted about advantages and challenges for supply chain partnering (SCP) in the construction sector, focus has been mostly on formal aspects of implementation within organizations. Understanding social aspects, however, might be just as crucial to implementation of SCP as understanding managerial and intraorganizational dynamics. Therefore, this paper presents the results of a study in which a work floor professional together with a researcher tried to contribute to the implementation of SCP within the maintenance and refurbishment processes of a Dutch housing association. The results showed that stakeholders could not come to shared understanding of strategic needs, and that that pattern influences and was influenced by social aspects such as leadership and trust, which confirms the importance of explicit attention for social interactions at work floor level for successful implementation of supply chain partnering.

description: We investigate which properties of protoplanetary disks around T Tauri stars affect the physics and chemistry in the regions where mid- and far-IR water lines originate and their respective line fluxes. We search for diagnostics for future observations. With the code ProDiMo, we build a series of models exploring a large parameter space, computing rotational and rovibrational transitions of water in nonlocal thermodynamic equilibrium (non-LTE). We select a sample of transitions in the mid- IR regime and the fundamental ortho and para water transitions in the far-IR. We investigate the chemistry and the local physical conditions in the line emitting regions. We calculate Spitzer spectra for each model and compare far-IR and mid-IR lines. In addition, we use mid-IR colors to tie the water line predictions to the dust continuum. Parameters affecting the water line fluxes in disks by more than a factor of three are : the disk gas mass, the dust-to-gas mass ratio, the dust maximum grain size, ISM(InterStellarMedium) UV radiation field, the mixing parameter of Dubrulle settling, the disk flaring parameter, and the dust size distribution. The first four parameters affect the mid-IR lines much more than the far-IR lines. A key driver behind water spectroscopy is the dust opacity, which sets the location of the water line emitting region. We identify three types of parameters. Parameters, such as dust-to-gas ratio, ISM radiation field, and dust size distribution, affect the mid-IR lines more, while the far-IR transitions are more affected by the flaring index. The gas mass greatly affects lines in both regimes. Higher spectral resolution and line sensitivities, like from the James Webb Space Telescope, are needed to detect a statistically relevant sample of individual water lines to distinguish further between these types of parameters.

description: We review the recent results of heavy meson diffusion in thermal hadronic matter. The interactions of D and B-bar mesons with other hadrons (light mesons and baryons) are extracted from effective field theories based on chiral and heavy-quark symmetries. When these guiding principles are combined with exact unitarity, physical values of the cross sections are obtained. These cross sections (which contain resonant contributions) are used to calculate the drag and diffusion coefficients of heavy mesons immersed in a thermal and dense medium. The transport coefficients are computed using a Fokker-Planck reduction of the Boltzmann equation.

description: Archival Suzaku data of the face-on spiral galaxy M101 were analyzed. An intense emission line at 6.72^{+0.10}_{-0.12} keV was detected in the central region. This line is identified with a K-line from He-like iron, which indicates the existence of a thin thermal plasma with a temperature of several keV. The iron line luminosity within the central 5 arcmin radius region is estimated to be (2-12)x10^{37} erg s^{-1}. The origin of the iron emission line is discussed.

Science for Galápagos?: science and its publics in the Galápagos Archipelago

Publisher: name: University of North Carolina at Chapel Hill
Year: 2014

description: In May 2011, UNC-CH and the Universidad San Francisco de Quito in Ecuador inaugurated the Galapagos Science Center in San Cristobal, Galapagos. The GSC signifies a new site for science in the archipelago, where the science-society relationship has been historically complex. Through examination of the GSC's outreach initiatives I ask, What is a science for Galapagos? Science for Galapagos, is a phrase from Santander et al. (2009) who argue that a science for the islands signifies a model of science in which research priorities are established by competent authorities according to real knowledge needs. (105) I revisit this definition, arguing that a science for Galapagos should incorporate Doreen Massey's (2005) theory of place as process. Science for Galapagos, then, is not a science that is tied to any singular understanding of--or vision for--the Galápagos but rather one that is open to engaging with the inherent multiplicity of place.

description: Data Documentation Initiative-Lifecycle (DDI-L) introduced a robust metadata model to support the capture of questionnaire content and flow, and encouraged through support for versioning and provenancing, objects such as BasedOn for the reuse of existing question items. However, the dearth of questionnaire banks including both question text and response domains has meant that an ecosystem to support the development of DDI ready CAI tools has been limited. Archives hold the information in PDFs associated with surveys, but extracting that in an efficient manner into DDI-Lifecycle is a significant challenge. While CLOSER Discovery has been championing the provision of high-quality questionnaire metadata in DDI-Lifecycle, this has primarily been done manually. More automated methods need to be explored to ensure scalable metadata annotation and uplift. This paper presents initial results in engineering a machine learning (ML) pipeline to automate the extraction of questions from survey questionnaires as PDFs. Using CLOSER Discovery as a ‘training dataset', a number of machine learning approaches have been explored to classify parsed text from questionnaires to be output as valid DDI items for inclusion in a DDI-L compliant repository. The developed ML pipeline adopts a continuous build and integrate approach, with processes in place to keep track of various combinations of the structured DDI-L input metadata, ML models and model parameters against the defined evaluation metrics, thus enabling reproducibility and comparative analysis of the experiments. Tangible outputs include a map of the various metadata and model parameters with the corresponding evaluation metrics' values, which enable model tuning as well as transparent management of data and experiments.

Becoming Each Other? Trends of Convergence in the Strategic Cultures of NATO and ESDP
Creators: name: Nikolits, Daniel
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: Strategic culture is a constructivist concept that seeks to understand and explain a security community's actions based upon the collective, identity-driven norms, ideas, and patterns of behavior regarding the pursuit of their security and defense goals. This thesis looks at the strategic cultures of NATO and the ESDP over the last decade. It seeks to place both organizations within matrices to visually represent their respective strategic cultures, and then to compare the trends in their evolution over that time frame through three case studies of missions where both organizations participated. It finds that, not only are the strategic cultures of both organizations broadening in scope and reach, but they are also converging toward each other. This suggests that mission overlap between them might occur with greater frequency in the future, presenting challenges but also greater opportunity for cooperation between them.
DETECTive: Machine Learning driven Automatic Test Pattern Prediction for Faults in Digital Circuits
Creators: name: Petrolo, Vincenzo
Publisher: name: University of Illinois at Chicago
Year: 2023

description: Design for testing is becoming a critical stage of the design process. This procedure helps detect electrical faults on a digital circuit and it is of paramount importance in safety-critical applications. Automatic Test Pattern Generation is the traditional algorithmic approach capable of finding all the test pattern sequences that detect the presence of electrical faults. Unfortunately, due to its NP-Complete nature the decision problem requires backtracking before converging to a solution. Even though heuristics have been developed to decrease the number of backtracks this remains the bottleneck when dealing with industrial-scale designs. To address this problem, we introduce the concept of “Automatic Test Pattern Prediction” (ATPP) that leverages the power of deep learning to predict test patterns instead of generating them. To this end, we present DETECTive, the first fully machine learning-based ATPG tool. The model is trained on small-scale circuits and our findings prove it to be effective on circuits up to four times larger, demonstrating that the model learns how to predict test patterns. Moreover, due to its non-backtracking nature, the model runs 11x faster than academic tools. We think that this research settles the basis for more sophisticated models that can perform predictions on industrial-scale designs. This could lead to a lower time required to reach high fault coverage, a shorter time-to-market for new chips, and safer devices.
Transform legacy study, question, and variable documentation into DDI 3.2 LC

description: Many service providers and institutions in the social sciences document survey data including study information, questions, and variables in self-developed legacy software in proprietary databases or other forms according to the specific needs and use cases. We introduce an easy-to-use REST API to create a DDI LC 3.2 documentation based on a use case of the question/variable documentation by SOEP (DIW). DIW has documented their questions and variables in CSV files using paneldata.org. The REST API is attached into the GESIS questionnaire editor. The resulting documentation is a self-contained DDI XML file including the study unit documentation, instruments, questions, answers, and connected variables. The documentation can be visually explored, evaluated or even further documented in the GESIS questionnaire editor, but also downloaded as DDI XML file or Word/PDF report. The created documentation can also be directly re-used for question search, e.g., based on the CESSDA European Question Bank. In addition, REST API is capable to import multiple languages and translations. A recorded versioin of this presentation can be found here: https://youtu.be/OKxZw57YKGs

description: We revisit the 3-states Potts model on random planar triangulations as a Hermitian matrix model. As a novelty, we obtain an algebraic curve which encodes the partition function on the disc with both fixed and mixed spin boundary conditions. We investigate the critical behaviour of this model and find scaling exponents consistent with previous literature. We argue that the conformal field theory that describes the double scaling limit is Liouville quantum gravity coupled to the $(A_4,D_4)$ minimal model with extended $\mathcal{W}_3$-symmetry.

Application of Distance Learning to Interactive Seminar Instruction in Orthodontic Residency Programs
Creators: name: Bednar, Eric David
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: A series of experiments involving 3 orthodontic departments has shown that distance learning can be acceptable to residents and effective in teaching concepts that are fundamental to orthodontic practice. The improvement from pre- to post-test scores after observing a sequence of distance seminars was similar to direct instruction. Orthodontic residents rated the educational experiences very positively. Live participation in seminars via video conferencing was preferred to live observation or later observation of a recording, but observation provided similar improvement in test scores. The acceptability of the distance seminars appeared to be influenced by the instructor's personality and teaching style in facilitating interaction, the seminar subject, the residents' comfort level in dealing with this technology, and the sequence for interaction vs observation. Further development of recorded seminars with live follow-up discussions has the potential to supplement instruction in graduate orthodontic programs and help with the impending shortage of experienced fulltime orthodontic faculty.

We present a second-order time integration method which preserves well the Poisson structure and compare it to commonly used algorithms, such as the Boris scheme. All the methods are represented in a general framework of splitting methods. We use the so-called $ϕ$ functions, which give efficient ways for both analyzing and implementing the algorithms. Numerical experiments show an excellent long term stability for the new method considered.

description: Peer reviewed: True
description: Previous literature has highlighted that women who have a pregnancy affected by gestational hypertension or preeclampsia are at higher risk of cardiovascular disease (CVD) in later life. However, CVD is a composite of multiple outcomes, including coronary heart disease, heart failure, and stroke, and the risk of both CVD and hypertensive disorders of pregnancy varies by the population studied. We conducted a narrative review of the risk of cardiovascular outcomes for women with prior gestational hypertension and pre-eclampsia. Previous literature is summarized by country and ethnicity, with a higher risk of CVD and coronary heart disease observed after gestational hypertension and a higher risk of CVD, coronary heart disease and heart failure observed after pre-eclampsia in most of the populations studied. Only one study was identified in a low- or middle-income country, and the majority of studies were conducted in white or mixed ethnicity populations. We discuss potential interventions to mitigate cardiovascular risk for these women in different settings and highlight the need for a greater understanding of the epidemiology of CVD risk after gestational hypertension and pre-eclampsia outside of high-income, white populations.
A Physics-First Approach to the Schwarzschild Metric

Year: 2016
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: As is well-known, the Schwarzschild metric cannot be derived based on pre-general-relativistic physics alone, which means using only special relativity, the Einstein equivalence principle and the Newtonian limit. The standard way to derive it is to employ Einstein's field equations. Yet, analogy with Newtonian gravity and electrodynamics suggests that a more constructive way towards the gravitational field of a point mass might exist. As it turns out, the additional physics needed is captured in two plausible postulates. These permit to deduce the exact Schwarzschild metric without invoking the field equations. Since they express requirements essentially designed for use with the spherically symmetric case, they are less general and powerful than the postulates from which Einstein constructed the field equations. It is shown that these imply the postulates given here but that the converse is not quite true. The approach provides a fairly fast method to calculate the Schwarzschild metric in arbitrary coordinates exhibiting stationarity and sheds new light on the behavior of waves in gravitational fields.

Generating synthetic data on the basis of metadata
Creators: name: van Kesteren, Erik-Jan
Publisher: name: Zenodo
Year: 2021

description: The Dutch Central Bureau of Statistics (CBS) possesses extremely valuable sensitive datasets with information on the entire population of the Netherlands. Researchers in the Netherlands may gain secure access to these datasets after submitting a detailed proposal with information on which datasets are required to answer their research question. However, it is difficult, time-consuming, and costly to manually comb through the metadata to understand whether and how the available data may answer their question of interest. To help researchers in this initial exploration step, we are developing a software program that generates synthetic example data (public use files) based on variable-level information from public metadata -- e.g., means, standard deviations, range, variable names and types, and dataset size. Using this synthetic data, researchers can define their requirements and even write analysis code before formally requesting access. In this talk, I will show off a prototype app (https://github.com/sodascience/ddi-synth), discuss the implications, and talk about how this concept can grow in the future. We intend for this software to integrate with the Dataverse instance in development at ODISSEI, the the Dutch Social Science research infrastructure, and we are considering the DDI metadata format for this task.

description: We study the evolution of the two scalar fields entangled via a mutual interaction in an expanding spacetime. We compute the logarithmic negativity to leading order in perturbation theory and show that for lowest order in the coupling constants, the mutual interaction will give rise to the survival of the quantum correlations in the limit of the smooth expansion. The results suggest that interacting fields can codify more information about the underlying expansion spacetime and lead to interesting observable effects.

Their structures were elucidated by comprehensive spectroscopic methods, including infrared and nuclear magnetic resonance. Compound 1 is the first example of salicylic acid linking a carboxylated α-pyrone via an ethyl bridge. Beyond expanding the knowledge of the chemical diversity of D. moldavica, both compounds 1 and 2 were shown to upregulate the expression of Kruppel-like factor 2, which could serve as a prospective therapeutic target for the treatment of atherosclerosis.
Optimisation of the Population Monte Carlo algorithm: Application to constraining isocurvature models with cosmic microwave background data

Year: 2015
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: We optimise the parameters of the Population Monte Carlo algorithm using numerical simulations. The optimisation is based on an efficiency statistic related to the number of samples evaluated prior to convergence, and is applied to a D-dimensional Gaussian distribution to derive optimal scaling laws for the algorithm parameters. More complex distributions such as the banana and bimodal distributions are also studied. We apply these results to a cosmological parameter estimation problem that uses CMB anisotropy data from the WMAP nine-year release to constrain a six parameter adiabatic model and a fifteen parameter admixture model, consisting of correlated adiabatic and isocurvature perturbations. In the case of the adiabatic model and the admixture model we find respective degradation factors of three and twenty, relative to the optimal Gaussian case, due to degeneracies in the underlying parameter space. The WMAP nine-year data constrain the admixture model to have an isocurvature fraction of at most $36.3 \pm 2.8$ percent.

description: At the moment, social scientists are using different and sometimes proprietary software which processes metadata in different ways to analyze their data. Different data formats of statistical software packages, which are only partially compatible, represent an obstacle for replication studies. In particular, proprietary data formats endanger the requirement of interoperability anchored in the FAIR principles. Our project aimed to address this problem by introducing a metadata-enriched open data format that can be easily accessible, readable and interoperable in various statistical software. As a first milestone, we would like to present the conceptual model of an open data format, where DDI might come into play, and a minimal data example derived from survey data. Furthermore, we would like to discuss our preliminary work on importing the open-data format into (proprietary) statistical programs and converting data of a proprietary format into the open format.

title: Constructing an Understanding of Professional Academic Writing: The SEPIA Model
Creators: name: Grant, Maria
Publisher: name: Liverpool John Moores University
Year: 2023

description: Background Professional academic writing is a key part of an academic’s role within higher education institutions (HEIs), though only a subset of academics publishes on a regular basis. This research sought to identify the process or processes that help academics write for publication. Methodology A convergent mixed methods grounded theory methodology was used. Social network analysis of the longitudinal development of co-author personal networks (ego-nets) of four highly published academics informed the staged sampling (purposive, then theoretical) of eight academics employed in HEI nursing departments: Australia; Belgium; Canada; Italy; Singapore; United Kingdom; United States of America. Open-ended interviews were recorded and transcribed verbatim. Constant comparative analysis (CCA) of transcripts, diagramming and story lining, were employed in the construction of a substantive grounded theory. Results Ego-net analysis of co-author relationships (number, employer, country, gender) indicated it takes 4-to-7 years from first co-authored publication to achieve the sustained levels of publication desired by HEIs. The SEPIA Model of how academics conceptualise the breadth of professional academic writing was constructed from interview data. Sector: Organisational/Publishing context. Equipping: Generalised pursuits preceding writing. Purpose and Identity: Attributes to maintain a sustained and focused engagement with professional academic writing. Activity: Process of writing. Discussion The SEPIA Model highlighted the disjointed and inconsistent levels of awareness and access to professional academic writing and research development; best characterised as an emphasis in supporting writing Activity, while largely being unaware or ignoring Sector, Equipping, Purpose and Identity. The sustaining influence of an academics’ sense of purpose and professional identity may provide a practical route to enhancing professional academic writing support. Conclusion The SEPIA Model provides a framework for holistic and equitable programmes of professional academic writing support, engagement and networking. Medium-term investment may be required before the impact of that investment becomes apparent.
Testing moderation: physical punishment, parental warmth, and aggression
Creators: name: McRae, Michael Todd
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Physical punishment is a disciplinary technique that many parents utilize and report as being effective. Nevertheless, researchers continue to debate its usefulness and impact on child adjustment. Many have argued that physical punishment is detrimental to children's socio-emotional functioning, and in particular, that it increases aggression. However, some have argued that whether parents utilize physical punishment is less important than how they use it, citing strong evidence that not all children who are spanked display abnormal levels of aggression. This has lead to the theory that various parenting characteristics and techniques may moderate the relationship between physical punishment and aggression. The current study examines parental warmth as a moderator of the relationship between physical punishment and aggression 30 months later. Results of the study yielded no evidence that this relationship exists. Several limitations are believed to have contributed to the null findings. Directions for future research are discussed.

description: International shipping is the backbone of the global economy with ~80% of the world’s trade (by volume) transported by ship. The potential environmental impacts of this multi-billion-dollar industry have received considerable attention, particularly emissions into air and sea. Many of these large commercial vessels lay at anchor for extended periods while awaiting their turn to enter port, and yet the impacts associated with anchoring remain virtually unexamined. Anchors can exceed 20 tonnes, with chains up to hundreds of metres in length and individual links weighing up to 200kg; there is potential for significant effects on seafloor biota where anchoring is concentrated. Filling knowledge gaps in deep-water wave-exposed environments is logistically challenging and expensive. To do so we used sediment grabs collected offshore from the Port of Newcastle (SE Australia) – the world’s largest coal export terminal – to sample infaunal assemblages in anchor-affected locations relative to reference locations (30 to 55m water depth). Polychaetes and crustaceans were the most abundant biota in the samples (~85%), whereas molluscs were very low in abundance (<3%), despite being well represented in terms of diversity (11 families of bivalves and 9 families of gastropods). Invertebrate abundance almost doubled in areas exposed to anchoring compared to reference areas. In contrast, invertebrate diversity declined with increasing anchoring activity, however this relationship was weak. Importantly, we observed major shifts in the overall invertebrate assemblage at anchored-affected locations – with reductions in suspension feeders mirrored by increases in scavengers and predators. We assert that suspension feeders were negatively impacted by sediment mobilisation or direct physical damage from anchor chains, while opportunistic scavengers and mobile predators benefitted from this disturbance. We contend that anchor disturbance is a global issue given burgeoning marine trade. Data on the effects of anchoring are urgently required to better inform the management of environments regularly used as anchorages.

description: Let $Φ:\mathfrak{S}(M_1)\to \mathfrak{S}(M_2)$ be a bijection (not assumed affine nor continuous) between the sets of normal states of two quantum systems, modelled on the self-adjoint parts of von Neumann algebras $M_1$ and $M_2$, respectively. This paper concerns with the situation when $Φ$ preserves (or partially preserves) one of the following three notions of "transition probability" on the normal state spaces: the Uhlmann transition probability $P_U$, the Raggio transition probability $P_B$ and an "asymmetric transition probability" $P_0$ as defined in this article. It is shown that the two systems are isomorphic, i.e. $M_1$ and $M_2$ are Jordan $^*$-isomorphic, if $Φ$ preserves all pairs with zero Uhlmann (respectively, Raggio or asymmetric) transition probability, i.e., for any normal states $μ$ and $ν$, we have $$ P\big(Φ(μ),Φ(ν)\big) = 0 \quad \text{if and only if} \quad P(μ,ν)=0, $$ where $P$ stands for $P_U$ (respectively, $P_R$ or $P_0$). Furthermore, as an extension of Wigner's theorem, it is shown that there is a Jordan $^*$-isomorphism $Θ:M_2\to M_1$ with $$Φ= Θ^*|_{\mathfrak{S}(M_1)}$$ if and only if $Φ$ preserves the "asymmetric transition probability". This is also equivalent to $Φ$ preserving the Raggio transition probability. Consequently, if $Φ$ preserves the Raggio transition probability, it will preserve the Uhlmann transition probability as well. As another application, the sets of normal states equipped with either the usual metric, the Bures metric or "the metric induced by the self-dual cone" are complete Jordan $^*$-invariants for the underlying von Neumann algebras.

description: We study the computational complexity of planar valued constraint satisfaction problems (VCSPs), which require the incidence graph of the instance be planar. First, we show that intractable Boolean VCSPs have to be self-complementary to be tractable in the planar setting, thus extending a corresponding result of Dvorak and Kupec [ICALP'15] from CSPs to VCSPs. Second, we give a complete complexity classification of conservative planar VCSPs on arbitrary finite domains. In this case planarity does not lead to any new tractable cases and thus our classification is a sharpening of the classification of conservative VCSPs by Kolmogorov and Zivny [JACM'13].

description: We analyze the stability of the Rate Control Protocol (RCP) using two different models that have been proposed in literature. Our objective is to better understand the impact of the protocol parameters and the effect different forms of feedback have on the stability of the network. We also highlight that different time scales, depending on the propagation delay relative to the queuing delay, have an impact on the nonlinear and the stochastic properties of the protocol fluid models. To better understand some of the nonlinear properties, we resort to local bifurcation analysis where we exhibit the existence of a Hopf type bifurcation that then leads to stable limit cycles. Our work serves as a step towards a more comprehensive understanding of the nonlinear fluid models that have been used as representative models for RCP.

Making metadata FAIR: Combining DDI solutions with other standards in official statistics

description: Metadata in statistical production is ubiquitous: from concepts, classifications and variables to retention and provenance information, metadata is created, used and shared across all phases of the data lifecycle. Unfortunately, metadata management is sometimes silo-based and tool-specific, which impairs all four FAIR principles (Findable, Accessible, Interoperable, Reusable). Statistics Canada is in the early stages of implementing a virtual metadata integration platform, the Metadata Hub, that integrates a collection of metadata repositories, e.g. Colectica, Aria, SDMX Istat Toolkit, OpenLink Virtuoso and CKAN across a number of standards, e.g. DDI, SDMX, XKOS, DCAT, and RDF/OWL, among others. In this presentation we describe our experience so far and the way forward A recorded version of this talk can be found here: https://youtu.be/-90rq_IlxQM

description: Regulation of the engineering profession is critical in developing and safeguarding the nation’s infrastructural systems. The regulation of engineering education through separate legal provisions of both the Commission for University Education (CUE) and Engineering Board of Kenya (EBK) resulted in uncoordinated and sometimes contradicting directives. The attempt by the University (Amendment) Act No. 48 2016, which was upheld by the High Court ruling of 2020, to resolve the duality by vesting the mandate for accreditation of programmes on CUE has created gaps in the regulation of the engineering profession. This policy brief traces regulation of university education in Kenya, identifies the regulatory gaps and suggests mitigation measures.

description: When droplets impact fibrous media, the liquid can be captured by the fibers or contact then break away. Previous studies have shown that the efficiency of drop capture by a rigid fiber depends on the impact velocity and defined a threshold velocity below which the drop is captured. However, it is necessary to consider the coupling of elastic and capillary effects to achieve a greater understanding of the capture process for soft substrates. Here, we study experimentally the dynamics of a single drop impacting on a thin flexible fiber. Our results demonstrate that the threshold capture velocity depends on the flexibility of fibers in a non-monotonic way. We conclude that tuning the mechanical properties of fibers can optimize the efficiency of droplet capture.
