description: A basic algorithmic task in automated video surveillance is to separate background and foreground objects. Camera tampering, noisy videos, low frame rate, etc., pose difficulties in solving the problem. A general approach that classifies the tampered frames, and performs subsequent analysis on the remaining frames after discarding the tampered ones, results in loss of information. Several robust methods based on robust principal component analysis (PCA) have been introduced to solve this problem. To date, considerable effort has been expended to develop robust PCA via Principal Component Pursuit (PCP) methods with reduced computational cost and visually appealing foreground detection. However, the convex optimizations used in these algorithms do not scale well to real-world large datasets due to large matrix inversion steps. Also, an integral component of these foreground detection algorithms is singular value decomposition which is nonrobust. In this paper, we present a new video surveillance background modelling algorithm based on a new robust singular value decomposition technique rSVDdpd which takes care of both these issues. We also demonstrate the superiority of our proposed algorithm on a benchmark dataset and a new real-life video surveillance dataset in the presence of camera tampering. Software codes and additional illustrations are made available at the accompanying website rSVDdpd Homepage (https://subroy13.github.io/rsvddpd-home/)

description: Presented in this thesis is the improvement and characterization of a high-intensity cold atom source. The source produces a continuous cold beam of ⁷Li atoms by seeding an effusive ⁷Li beam into a supersonic helium jet. The atomic beam is then brought to a focus using a magnetic hexapole lens. Fluorescence and absorption spectroscopy of the focused beam indicates a longitudinal temperature of 7(3) mK, forward velocity of 211(2) m/s, flux of 2.3(4) × 10¹² s⁻¹, and a peak brightness of 1.8(6) × 10¹⁹ m⁻²s⁻¹sr⁻¹. Results of the seeding process agree with a three-dimensional Monte Carlo simulation. Simulations also predict that seeding of heavier species into the jet, specifically ⁸⁷Rb, should be possible. With a number of modifications to the current source, a 30 times increase in the focused flux is predicted. In the later part of this thesis, results for ⁷Li⁴He dimer formation in the jet are discussed. The dimers form via three-body collisions ⁷Li + ⁴He + ⁴He → ⁷Li⁴He + ⁴He and are detected with laser-induced fluorescence. About 0.1% of the injected ⁷Li atoms form dimers with a temperature of ≈ 10 mK. Most of the collisions in the expansion occur in the k [ subscript B] × 1 mK to k [subscript B] × 100 mK range, where k [subscript B] is Boltzmann constant. As such, this method opens up the possibility to explore dimer formation for various weakly bound van der Waals molecules. Lastly, evidence for photoassociation resonance is presented and used to estimate the ground state binding energy of ⁷Li⁴He.

description: We study the geodesic two- and three-point functions of random weighted cubic maps, which are obtained by assigning random edge lengths to random cubic planar maps. Explicit expressions are obtained by taking limits of recently established bivariate multi-point functions of general planar maps. We give an alternative interpretation of the two-point function in terms of an Eden model exploration process on a random planar triangulation. Finally, the scaling limits of the multi-point functions are studied, showing in particular that the two- and three-point functions of the Brownian map are recovered as the number of faces is taken to infinity.

description: Electron scattering provides a powerful tool to determine charge distributions and transition densities of nuclei. This tool will soon be available for short-lived neutron-rich nuclei. [Purpose] Beyond mean-field methods have been successfully applied to the study of excitation spectra of nuclei in the whole nuclear chart. These methods permit to determine energies and transition probabilities starting from an effective in-medium nucleon-nucleon interaction but without other phenomenological ingredients. Such a method has recently been extended to calculate the charge density of nuclei deformed at the mean-field level of approximation [J. M. Yao et al., Phys. Rev. C86, 014310 (2012)]. The aim of this work is to further extend the method to the determination of transition densities between low-lying excited states. [Method] The starting point of our method is a set of Hartree-Fock-Bogoliubov wave functions generated with a constraint on the axial quadrupole moment and using a Skyrme energy density functional. Correlations beyond the mean field are introduced by projecting mean-field wave functions on angular-momentum and particle number and by mixing the symmetry restored wave functions.[Results] We give in this paper detailed formulae derived for the calculation of densities and form factors. These formulae are rather easy to obtain when both initial and final states are $0^+$ states but are far from being trivial when one of the states has a finite $J$-value. Illustrative applications to $^{24}$Mg and to the even-mass $^{58-68}$Ni have permitted to analyse the main features of our method, in particular the effect of deformation on densities and form factors. An illustration calculation of both elastic and inelastic scattering form factors is presented....

description: Alzheimer's disease causes significant memory loss and negatively affects cognitive abilities such as spatial navigation. However, few widespread treatments and tests can effectively screen and help patients with Alzheimer's. Studies have shown that spatial navigation tests can be more accurate than traditional tests in screening for Alzheimer's, presenting itself as a low-cost alternative. Serious games, another innovative approach in Alzheimer's research, have proven more effective than traditional medications in treating dementia, often caused by Alzheimer's. To expand on these findings, a spatial navigation game was created where users go through a maze to find the end, testing their spatial navigation skills and memory. The game procedurally generates mazes and adjusts the maze difficulty using Artificial Intelligence (AI), eventually rating the user's performance based on the distance the user traveled, the shortest path, and the path's difficulty. The game can differentiate players based on their navigation and memory through these adjustments and ratings, presenting itself as a potential early identifier for patients with Alzheimer's and other cognitive diseases. Given that spatial navigation is distinguishable from other cognitive functions, spatial navigation games could be highly beneficial when screening and treating patients with Alzheimer's, helping to track and assess cognitive behavior, brain training for improved cognition, and providing preventive measures.

description: This thesis is a stylistic examination of A New Leaf, The Heartbreak Kid, and Ishtar, three films directed by Elaine May. By analyzing the functions of recurring formal patterns and individual stylistic devices within the contexts surrounding these films, this study aims to take the first step in comprehensively situating May’s poetics. Taking into account not only the formal elements of May’s work, I survey historical, industrial, and cultural forces which played a role in the creation of these films. By assessing classical Hollywood genres May regularly interpolates, engaging with discourse surrounding these films and her career at large, and considering the industrial factors which shaped these films, this thesis reveals a contextual framework closely intertwined with May’s style. Throughout this thesis I will examine a set of persistent formal patterns seen in each of these films. May regularly revised and reversed tropes from the traditions of screwball, romantic, and dark comedy, shaping a set of stories and characters which subverted hegemony. I argue May brought key stylistic elements from her previous forms of expression, the theater and sketch comedy, to film through her continual emphasis on gags and performance. One of my principal aims is to demonstrate the aesthetic merit in May’s visual strategies, an area in which critics and scholars frequently dismiss her. These three films definitively demonstrate precision in composition, staging, and editing amongst other devices. I also point out the ways the films stylistically differ from one another and how these differences can often be traced back to the various industrial and personal factors surrounding them. This thesis enriches the discourse surrounding the work of Elaine May by providing a contextually informed aesthetic appraisal of the three comedies she directed.

description: The goal of this work is to study geometric properties of geometrically irreducible subschemes on degenerations of Fano varieties (more generally, of separably rationally connected varieties). It is known that these geometrically irreducible subschemes exist when the ground field has characteristic zero or contains an algebraically closed subfield. We show that the dimension of this geometrically irreducible subscheme has a lower bound by the Fano index of the generic fibre.

description: We study SUSY signatures at the 7, 8 and 14 TeV LHC employing the 19-parameter, R-Parity conserving p(henomenological)MSSM, in the scenario with a neutralino LSP. Our results were obtained via a fast Monte Carlo simulation of the ATLAS SUSY analysis suite. The flexibility of this framework allows us to study a wide variety of SUSY phenomena simultaneously and to probe for weak spots in existing SUSY search analyses. We determine the ranges of the sparticle masses that are either disfavored or allowed after the searches with the 7 and 8 TeV data sets are combined. We find that natural SUSY models with light squarks and gluinos remain viable. We extrapolate to 14 TeV with both 300 fb$^{-1}$ and 3 ab$^{-1}$ of integrated luminosity and determine the expected sensitivity of the jets + MET and stop searches to the pMSSM parameter space. We find that the high-luminosity LHC will be powerful in probing SUSY with neutralino LSPs and can provide a more definitive statement on the existence of natural Supersymmetry.

description: We study the homotopy groups of open books in terms of those of their pages and bindings. Under homotopy theoretic conditions on the monodromy we prove an integral decomposition result for the based loop space on an open book, and under more relaxed conditions prove a rational loop space decomposition. The latter case allows for a rational dichotomy theorem for open books, as an extension of the classical dichotomy in rational homotopy theory. As a direct application, we show that for Milnor's open book decomposition of an odd sphere with monodromy of finite order the induced action of the monodromy on the homology groups of its page cannot be nilpotent.

description: Recent works on massive multiple-input multiple-output (MIMO) have shown that a potential breakthrough in capacity gains can be achieved by deploying a very large number of antennas at the basestation. In order to achieve the performance that massive MIMO systems promise, accurate transmit-side channel state information (CSI) should be available at the basestation. While transmit-side CSI can be obtained by employing channel reciprocity in time division duplexing (TDD) systems, explicit feedback of CSI from the user terminal to the basestation is needed for frequency division duplexing (FDD) systems. In this paper, we propose an antenna grouping based feedback reduction technique for FDD-based massive MIMO systems. The proposed algorithm, dubbed antenna group beamforming (AGB), maps multiple correlated antenna elements to a single representative value using pre-designed patterns. The proposed method modifies the feedback packet by introducing the concept of a header to select a suitable group pattern and a payload to quantize the reduced dimension channel vector. Simulation results show that the proposed method achieves significant feedback overhead reduction over conventional approach performing the vector quantization of whole channel vector under the same target sum rate requirement.

description: We investigate the feasibility of measuring weak gravitational lensing using 21cm intensity mapping with special emphasis on the performance of the planned Square Kilometre Array (SKA). We find that the current design for SKA-Mid should be able to measure the evolution of the lensing power spectrum at z~2-3 using this technique. This will be a probe of the expansion history of the universe and gravity at a unique range in redshift. The signal-to-noise is found to be highly dependent on evolution of the neutral hydrogen fraction in the universe with a higher HI density resulting in stronger signal. With realistic models for this, SKA Phase 1 should be capable of measuring the lensing power spectrum and its evolution. The signal-to-noise's dependence on the area and diameter of the telescope array is quantified. We further demonstrate the applications of this technique by applying it to two specific coupled dark energy models that would be difficult to observationally distinguish without information from this range of redshift. We also investigate measuring the lensing signal with 21cm emission from the Epoch of Reionization (EoR) using SKA-Low and find that it is unlikely to constrain cosmological parameters because of the small survey size, but could provide a map of the dark matter within a small region of the sky.

description: The global ocean absorbs significant amounts of human-induced CO2 emissions and the associated heat that CO2 traps in the atmosphere as a greenhouse gas. However, the long-term effects of warming oceans on climate and ocean circulation remains poorly understood. Climate model forecasts predict that ongoing global warming will lead to a more stratified ocean and weaker global ocean circulation in the near-term, with major ramifications for regional and global climates. However, they disagree on what will occur in the long-term as the deep ocean slowly adjusts to surface warming. To gain further insight into the long-term response of the ocean to global warming, our study focuses on the Pliocene Epoch (5.33 to 2.58 million years ago), the most recent geologic interval during which atmospheric carbon dioxide concentrations were similar to today, and temperatures were several degrees warmer. Recent studies suggest that the warm conditions of the Pliocene supported North Pacific Deep-Water formation and a Pacific Meridional Overturning Circulation, two phenomena that are absent in the modern ocean due to the freshness of surface waters in the subpolar North Pacific. The study builds a quantitative framework for how the presence of North Pacific Deep-Water formation during the Pliocene will imprint on the planktonic and benthic foraminiferal δ¹⁸O records that will be generated from 5 different sites in the North Pacific Ocean. These sites were chosen for their proximity to hypothesized Pliocene deep-water sites and deep-water circulation pathways that would allow them to detect a signal associated with a Pacific Meridional Overturning Circulation. We employ a forward modeling technique to simulate “synthetic” foraminiferal δ¹⁸Ocarbonate records using temperature and salinity fields for 5 different sites in the Pacific Ocean. We create synthetic δ¹⁸Ocarbonate time series’ using temperature and salinity fields from modern-day reanalysis data (ORAS5) and a Pre-industrial climate model (CESM) simulation, both of which don’t have North Pacific Deepwater formation, as well as a Pliocene simulation which has North Pacific Deepwater formation. These synthetic records quantify the fingerprints of Pliocene North Pacific Deep-Water Formation and will aid in the interpretation of the planktonic and benthic foraminiferal δ¹⁸O records that will be generated over the coming years for each site in the North Pacific Ocean. We acknowledge the feedback received in designing this research project from our collaborators on NSF award “Collaborative Research: Tracing Pacific Ocean circulation and ventilation during the warm Pliocene Epoch”, which the findings from our study will feed back into.

description: General circulation models (GCMs) are complex models used to predict future climate under various greenhouse gas emissions scenarios. However, when different GCMs simulate the same scenario, there is widespread variability in the final climate. One of the leading causes of the spread has been attributed to differing low-cloud feedback between the GCMs. To address this, Erfani & Burls (2020) conducted a suite of idealized, fully-coupled, climate model simulations under abrupt doubling of CO2 concentrations with varying strengths of low-cloud feedback. This study uses the output from the simulations in Erfani & Burls to study the transient response of the sea surface temperature (SST) gradient between the west and east Pacific, known as the zonal gradient, which has a strong impact on global atmospheric conditions as exemplified by El Nino and La Nina events. We find an initial increase in the zonal gradient which resembles the thermostat mechanism. This mechanism proposes that the eastern Pacific will warm more slowly than the western Pacific under uniform warming as a result of the upwelling of cold waters, thus increasing the zonal gradient. In the long term, however, the equilibrium zonal gradient response driven by subtropical cells becomes more important, causing SSTs to increase across all feedback parameters, with more the positive parameters experiencing a greater reduction of the zonal gradient. A simplified box-model that simulates the essential coupled ocean-atmosphere dynamics is compared with the CESM results to determine if the box model is able to capture the behavior seen in the CESM simulated temperature gradients. This hierarchy of models approach seeks to improve our understanding of the processes controlling the response of the Tropical Pacific to global warming over the coming decades to centuries.

Es wurde auch untersucht, wie in Yosys Erweiterungen zu implementieren sind. Die Analyse hat gezeigt, dass ein wichtiger Teil der Synthese die Umwandlung von Prozessen in eine RTL-Beschreibung darstellt. Im Rahmen der Synthese werden die, von einem Frontend vorläufig erzeugten RTL-Komponenten, umgewandelt. Der letzte Schritt der Synthese ist das Technologiemapping, welches die umgewandelten Komponente auf die verwendete Hardware anpasst.

Yosys implements a data structure RTLIL that is used to represent a design at all stages of synthesis. Yosys has a modular structure, which allows the user to expand the program. Synthesis in Yosys is divided into passes, each of which performs a specific task. As part of the thesis, the data structure and the passes were analyzed in detail. It was also examined how to implement extensions in Yosys. The analysis showed that an important part of the synthesis is the conversion of processes into RTL components. During the synthesis, the provisional RTL components generated by a frontend are converted. The last step of synthesis is technology mapping, which adapts the converted components to the used hardware.

description: Das steigende Bedürfnis nach individualisierten Produkten, in Kombination mit einer zunehmenden Erlebnisorientierung stellt GastronomInnen vor neue Herausforderungen. Co-Creation Prozesse stellen einen praktikablen Lösungsansatz dar. Auch wenn Co-Creation Prozesse in der Praxis immer häufiger Anwendung finden, fehlen oft theoretische Grundlagen die strukturierte Herangehensweisen ermöglichen. Die Literaturrecherche hat gezeigt, dass das Konzept Co-Creation zwar weitgehend erforscht ist, bislang aber noch nicht auf die Besonderheiten in der Gastronomie eingegangen wurde. Die sich auftuende Forschungslücke, wurde mit Hilfe von ExpertInneninterviews in dieser Arbeit geschlossen. Anhand einer qualitativen Inhaltsanalyse nach Kuckartz, wurden Hürden und Möglichkeiten einer Implementierung von Co-Creation Prozessen in der Gastronomie aufgezeigt. Daraus wurden Umsetzungsstrategien abgeleitet, die eine Implementierung erleichtern sollen. Die größten Hürden stellen strukturelle Veränderungen und eine ehrliche, transparente Kommunikation dar. Eine gesteigerte KundInnenzufriedenheit und damit einhergehende Loyalität, werden als größte Möglichkeiten einer gemeinsamen Leistungserstellung gesehen. Um die gefundenen Forschungsergebnisse zu generalisieren, können aufbauende quantitative Studien durchgeführt werden.

description: We investigate reductions of M-theory beyond twisted tori by allowing the presence of KK6 monopoles (KKO6-planes) compatible with N=4 supersymmetry in four dimensions. The presence of KKO6-planes proves crucial to achieve full moduli stabilisation as they generate new universal moduli powers in the scalar potential. The resulting gauged supergravities turn out to be compatible with a weak G2 holonomy at N=1 as well as at some non-supersymmetric AdS4 vacua. The M-theory flux vacua we present here cannot be obtained from ordinary type IIA orientifold reductions including background fluxes, D6-branes (O6-planes) and/or KK5 (KKO5) sources. However, from a four-dimensional point of view, they still admit a description in terms of so-called non-geometric fluxes. In this sense we provide the M-theory interpretation for such non-geometric type IIA flux vacua.

This construction has already been successfully applied to the de Sitter minimally coupled massless scalar field and massless spin-2 field to obtain a causal and fully covariant quantum field on the de Sitter background. We also consider the effects of boundary conditions. In this respect, Casimir energy-momentum tensor induced by Dirichlet boundary condition on a curved brane is evaluated.

description: Escape Rooms oder auch Breakouts sind im deutschsprachigen Raum keine weitverbreitete Unterrichtsmethode und deren Einfluss auf die Motivation der Schüler*innen ist nicht gut erforscht. Für den Physikunterricht gibt es kaum bestehende Breakouts, die für den Unterricht verwendet werden können. Diese Arbeit soll den Einfluss von Breakouts auf die intrinsische Motivation von Schüler*innen im Physikunterricht untersuchen. Dafür wird ein Breakout für den Mechanikunterricht in der 2.Klasse (Sek. I) entwickelt und in einem Pretest-Posttest-Verfahren dessen Einfluss auf die intrinsische Motivation der Schüler*innen ermittelt. Der verwendete Fragebogen basiert auf der Self Determination Theory. Es konnte festgestellt werden, dass das Breakout vor allem das Kompetenzerleben fördert und den Druck auf die Schüler*innen reduziert. Die Ergebnisse zeigen weiters, dass Schüler*innen bei der Bearbeitung des Breakouts die Gruppenarbeit und das Lösen der Puzzles besonders positiv wahrnehmen.

There are hardly any existing breakouts that can be used for physics lessons. This paper aims to investigate the influence of breakouts on students' intrinsic motivation in physics classes. For this purpose, a breakout for mechanics lessons in the 2nd grade (Sek. I) is developed and its influence on the intrinsic motivation of the students is developed in a pretest-posttest procedure. The questionnaire used is based on the Self Determination Theory. It was found that the breakout primarily promotes the experience of competence and reduces the pressure on the students. The results also show that students perceive the group work and the solving of the puzzles as particularly positive when working on the breakout.

description: We demonstrate an efficient control of $^{29}$Si nuclear spin orientation for specific lattice sites near $^{31}$P donors in silicon crystals at temperatures below 1 K and in high magnetic field of 4.6 T. Excitation of the forbidden electron-nuclear transitions leads to a pattern of narrow holes and peaks in the ESR lines of $^{31}$P. The pattern originates from dynamic polarization the $^{29}$Si nuclear spins near the donors via the solid effect. This method can be used for initialization of qubits based on $^{29}$Si nuclear spins in the all-silicon quantum computer. In comparison, polarization of $^{29}$Si performed by pumping the allowed ESR transitions, did not create any patterns. Instead, a single narrow spectral hole was burnt in the ESR line. The difference is explained by a rapid spin diffusion during the microwave pumping of the allowed transitions.
The Impact of Gamification on Motivation and Engagement in Game-based Learning Environments - A Literature Review

description: The field of educational technology and game-based learning has gained increased interest as educators seek innovative approaches to enhance student motivation and engagement. Existing studies have explored the effects of gamification on learning outcomes, yet a systematic literature review specifically focusing on the impact of gamification on motivation and engagement in game-based learning environments remains absent. Four research studies on this topic were analyzed, examining various gamification techniques and their effects on learners' motivational levels and engagement behaviors. The findings revealed that gamification, when thoughtfully integrated into game-based learning environments, significantly enhances learners' motivation and engagement. Key gamification elements, such as points, badges, and leaderboards, positively influenced intrinsic motivation, leading to increased enthusiasm, persistence, and interest in taking on challenges. Gamification positively influences students' learning, engagement, and behavior, regardless of their personality traits. However, individuals with higher levels of openness and extraversion tend to show increased engagement and enthusiasm in gamified learning environments. By understanding the impact of different gamification techniques on motivation and engagement, educators and instructional designers can adjust their strategies to create immersive and rewarding learning environments, using gamification as an effective tool to foster a positive and engaging learning experience.

title: Recht auf Wasser, Privatisierung und Verwaltung von Wasserressourcen im internationalen Recht
Creators: name: Mavridis, Ioannis
Year: 2021

description: In der vorliegenden Arbeit wird zunächst einmal die rechtliche Lage bzw. der rechtliche Schutz des Menschenrechts auf Wasser festgelegt. Einschlägige internationale Verträge werden dabei herangezogen und analysiert. Als Nächstes wird die Beziehung zwischen dieses Recht und der global ansteigenden Privatisierung der Wasserversorgungssysteme erörtert. Insbesondere wird untersucht, ob letztere mit dem Recht auf Wasser in Konflikt geraten könnte. Im Rahmen der EU und der WTO gibt es rechtliche Regelungen und Rechtsprechung, die diese Frage aufgreifen und die in dieser Arbeit bearbeitet werden. Der Zweite Teil der Arbeit betrifft die Beschränkungen, die das WTO-Recht den Staaten hinsichtlich der Verwaltung derer Wasserressourcen auferlegt. Darf ein Staat Beschränkungen in Bezug auf den Export von Wasservorkommen durchsetzen? Oder würde eine solche Maßnahme gegen das WTO-Recht verstoßen? Inwiefern kann letztendlich ein Staate seine eigenen Ressourcen selbstständig verfügen? Diese Verfassung dieser Arbeit dient also der Feststellung der internationalen Regelungen über das Recht auf Wasser der Einzelpersonen und das Recht der Staaten auf Verwaltung ihrer Wasserressourcen.

RG Analysis for Quantum Gravity with A Single Dimensionless Coupling

description: We study the quantum conformal gravity whose dynamics is governed by a single dimensionless gravitational coupling with negative beta function. Since the Euler term is not dynamical classically, the constant in front of it is not an independent coupling. Quantum mechanically, however, it induces the Riegert conformal-factor dynamics with BRST conformal symmetry representing background free nature. In this paper, we propose how to handle the Euler term systematically incorporating such dynamics on the basis of renormalization group analysis using dimensional regularization. As a non-trivial test of renormalization, we explicitly calculate the three-loop anomalous dimension of the cosmological constant operator and show that it agrees with the exact expression derived using the BRST conformal symmetry. The physical significance to inflation and CMB is also discussed.

A quasi-experimental evaluation of a research grant program: the tale of varied results based on different outcome variables, analysis periods, and estimation methods
Creators: name: Ploszaj, Adam
Publisher: name: Zenodo
Year: 2022

description: A summary of the results of quasi-experimental analyses is presented in Table 5 below. The analysis provides strong evidence that the Leader program has an impact on the patent activity of its beneficiaries. The effect is essentially substantive: the receipt of a grant translates into one additional patent application (and patent received) within five years of the competition results (on average in the population of successful applicants). The obtained results also suggest an impact on the increase in the number of publications, but this effect is most pronounced in the case of the group of applicants who had the lowest chance of obtaining a Leader grant. It should be emphasized, however, that the parameters for insignificant variants of the analysis are consistently positive, which may suggest that with greater precision of estimation the effect could exceed the conventional statistical significance thresholds. The situation is slightly different in the case of received awards. Here, too, a positive local effect is observable. However, in other variants of the analysis, the estimated parameters are unstable, sometimes negative, and sometimes positive, which suggests that there is no effect across the entire population and that increasing the sample would only confirm the absence of this effect. For all other output variables, there is no reason to claim that the examined program has an impact. This research contributes to the literature primarily by presenting a comparison of the evaluation results based on various outcome variables, different timeframes of analyses, and three quasi-experimental methods. The analysis shows that conclusions based on different combinations of the above-mentioned dimensions can differ extensively and that only selected effects persist over most of the variants. This is a warning signal for policymakers, policy analysts, and evaluators because decisions regarding the scope and methods of the study turn out to have a major impact on the results of the evaluation.

description: Damage to the blood vessel triggers formation of a hemostatic plug, which is meant to prevent bleeding, yet the same phenomenon may result in a total blockade of a blood vessel by a thrombus, causing severe medical conditions. Here, we show that the physical interplay between platelet adhesion and hemodynamics in a microchannel manifests in a critical threshold behavior of a growing thrombus. Depending on the size of injury, two distinct dynamic pathways of thrombosis were found: the formation of a nonocclusive plug, if injury length does not exceed the critical value, and the total occlusion of the vessel by the thrombus otherwise. We develop a mathematical model that demonstrates that switching between these regimes occurs as a result of a saddle-node bifurcation. Our study reveals the mechanism of self-regulation of thrombosis in blood microvessels and explains experimentally observed distinctions between thrombi of different physical etiology. This also can be useful for the design of platelet-aggregation-inspired engineering solutions.
