description: We place functional constraints on the shape of the inflaton potential from the cosmic microwave background through a variant of the generalized slow roll approximation that allows large amplitude, rapidly changing deviations from scale-free conditions. Employing a principal component decomposition of the source function G'~3(V'/V)^2 - 2V''/V and keeping only those measured to better than 10% results in 5 nearly independent Gaussian constraints that maybe used to test any single-field inflationary model where such deviations are expected. The first component implies < 3% variations at the 100 Mpc scale. One component shows a 95% CL preference for deviations around the 300 Mpc scale at the ~10% level but the global significance is reduced considering the 5 components examined. This deviation also requires a change in the cold dark matter density which in a flat LCDM model is disfavored by current supernova and Hubble constant data and can be tested with future polarization or high multipole temperature data. Its impact resembles a local running of the tilt from multipoles 30-800 but is only marginally consistent with a constant running beyond this range. For this analysis, we have implemented a ~40x faster WMAP7 likelihood method which we have made publicly available.

Accelerating Compact Object Mergers in Triple Systems with the Kozai Resonance: A Mechanism for "Prompt" Type Ia Supernovae, Gamma-Ray Bursts, and Other Exotica

description: White dwarf-white dwarf (WD-WD) and neutron star-neutron star (NS-NS) mergers may produce Type Ia supernovae and gamma-ray bursts (GRBs), respectively. A general problem is how to produce binaries with semi-major axes small enough to in significantly less than the Hubble time (t_H), and thus accommodate the observation that these events closely follow episodes of star formation. I explore the possibility that such systems are not binaries at all, but actually coeval, or dynamical formed, triple systems. The tertiary induces Kozai oscillations in the inner binary, driving it to high eccentricity, and reducing its gravitational wave (GW) merger timescale. This effect significantly increases the allowed range of binary period P such that the merger time is t_merge < t_H. In principle, Chandrasekhar-mass binaries with P ~ 300 days can merge in < t_H if they contain a prograde solar-mass tertiary at high enough inclination. For retrograde tertiaries, the maximum P such that t_merge < t_H is yet larger. In contrast, P < 0.3 days is required in the absence of a tertiary. I discuss implications of these findings for the production of transients formed via compact object binary mergers. Based on the statistics of solar-type binaries, I argue that many such binaries should be in triple systems affected by the Kozai resonance. If true, expectations for the mHz GW signal from individual sources, the diffuse background, and the foreground for GW experiments like LISA are modified. This work motivates future studies of triples systems of A, B,and O stars, and new types of searches for WD-WD binaries in triple systems.

ProtoGate: Prototype-based Neural Networks with Global-to-local Feature Selection for Tabular Biomedical Data

description: Tabular biomedical data poses challenges in machine learning because it is often high-dimensional and typically low-sample-size (HDLSS). Previous research has attempted to address these challenges via local feature selection, but existing approaches often fail to achieve optimal performance due to their limitation in identifying globally important features and their susceptibility to the co-adaptation problem. In this paper, we propose ProtoGate, a prototype-based neural model for feature selection on HDLSS data. ProtoGate first selects instance-wise features via adaptively balancing global and local feature selection. Furthermore, ProtoGate employs a non-parametric prototype-based prediction mechanism to tackle the co-adaptation problem, ensuring the feature selection results and predictions are consistent with underlying data clusters. We conduct comprehensive experiments to evaluate the performance and interpretability of ProtoGate on synthetic and real-world datasets. The results show that ProtoGate generally outperforms state-of-the-art methods in prediction accuracy by a clear margin while providing high-fidelity feature selection and explainable predictions.

description: Excerpts from the report: The 1961-62 survey of marketing, farm supply, and related service cooperatives showed a continuation of the upward trend in the total business volume, while the number of these cooperatives and their memberships continued to decrease. Total gross volume of business handled by these cooperatives, including interassociation business, amounted to $17.2 billion. This was an increase of 6.3 percent over the $16.2 billion reported in the previous year. Total net business, after adjusting the gross figure for business done between cooperatives, amounted to $13 billion. This was an increase of 5 percent over the $12.4 billion in 1960-61. The total number of these cooperatives decreased from 9,163 in 1960-61 to 9,039 in 1961-62. This was a net decrease of 124 associations. The total number of memberships in these 9,039 associations decreased from 7,202,895 in 1960-61 to 7,110,240 in 1961-62, representing a decrease of 1.3 percent.

description: A variational principle for Lagrangian densities containing derivatives of real order is formulated and the invariance of this principle is studied in two characteristic cases. Necessary and sufficient conditions for an infinitesimal transformation group (basic Nöther's identity) are obtained. These conditions extend the classical results, valid for integer order derivatives. A generalization of Nöther's theorem leading to conservation laws for fractional Euler-Lagrangian equation is obtained as well. Results are illustrated by several concrete examples. Finally, an approximation of a fractional Euler-Lagrangian equation by a system of integer order equations is used for the formulation of an approximated invariance condition and corresponding conservation laws.

Poltern-Stottern

description: Die vorliegende Bachelorarbeit untersucht im Rahmen einer qualitativen Einzelfallstudie die Generalisierungsphase einer logopädischen Therapie bei einer Mischform Poltern-Stottern, die mit einer 17-jährigen Jugendlichen an der Hochschule für Heilpädagogik Zürich (HfH) durchgeführt wurde. Die Aussagen der Klientin und ihrer Bezugsperson aus problemzentrierten Interviews und die teilnehmenden Beobachtungen der Therapeutinnen während der Therapie bildeten die Datengrundlage für eine qualitative Inhaltsanalyse. Aus dem Einzelfall konnten hilfreiche methodisch-didaktische Interventionen sowie Gelingensbedingungen und Hemmnisse bei der Generalisierung der Sprechtechnik in unterschiedliche alltägliche Sprechsituationen ermittelt werden. Auf Basis der mit theoretischen Erkenntnissen abgeglichenen Gelingensbedingungen und Hemmnissen formulierten die Autorinnen Interventionsempfehlungen. Diese wurden in einem weiteren Schritt mit zwei Expert*innen im Bereich Poltern und Stottern in Interviews validiert und unter Einbezug ihres Fachwissens weiterentwickelt. Entstanden sind elf Interventionsempfehlungen für die Generalisierungsphase bei einer Mischform Poltern-Stottern, an denen sich Logopäd*innen in der Therapie mit 15- bis 19-jährigen Jugendlichen orientieren können. Beispielsweise wird die Erstellung einer Hierarchie mit herausfordernden alltäglichen Sprechsituationen zur Steigerung des Bewusstseins für unterschiedliche kommunikative Anforderungen, das frühzeitige Einbinden der Bezugspersonen im Rahmen von Therapiebesuchen und mehr Mitbestimmung in der Therapie durch kontinuierliches Anbieten von Auswahlmöglichkeiten empfohlen.
Characteristics of complex adaptive systems in technology-mediated wound care communication processes

description: Wound management is a common healthcare concern that affects many people across the span of their lives. The complexity of wound care results in the necessity of an interdisciplinary approach with many team members communicating and sharing information. Communication can be a challenge in the complex and constantly evolving healthcare system. Describing the current state of processes of interdisciplinary wound care communication, as informed by complex adaptive systems theory, adds to the existing research regarding complex adaptive systems, communication and technology use in health care. In this thesis I used ethnographic methods and a complex adaptive systems analytic framework to explore the processes surrounding interdisciplinary wound care communication. Interviews were conducted with nine healthcare providers and facilitated through the use of professional personas. Through the interviews, categories and themes were identified and the results were reviewed to see to what extent wound care communication processes are reflective of complex adaptive systems. Three main themes were identified: How context shapes interdisciplinary communication; Navigation of tools and technologies; and Efficiency and trust in face-to-face communication. Each wound care communication category mapped to a minimum of two complex adaptive systems properties while some illustrated all eleven properties. Overall, the wound care communication categories exemplify the properties of a complex adaptive system which suggests that interdisciplinary wound care communication is a complex adaptive system. Despite the different technologies available to mediate interdisciplinary communication there was a resounding preference for face-to-face and in person communication whenever possible.

description: Excerpts from the report: Farm products marketed by cooperatives in 1962-63 had a gross value of almost $13.9 billion. This was about a 7-percent increase over the $13.0 billion in 1961-62. The net value of farm products marketed was more than $10.8 billion. The net figure reflects elimination of interassociation business and represents an increase of 6.6 percent over the comparable figure of almost $10.2 billion in the previous year. The total number of cooperatives in the survey dropped from 9,039 in 1961-62 to 8,907 in 1962-63. This was a net decrease of 132 associations. For the first time since 1958-59, when a temporary reversal 1 year in duration occurred, the downward trend in membership figures was reversed. In 1962-63, memberships in cooperatives increased by 119,770 and totaled 7,218,750.

description: Il Piano di studio della scuola dell’obbligo si propone di lavorare sullo sviluppo delle competenze dell’allievo, che inglobano non solo ambiti disciplinari ma anche competenze che andranno a creare il “futuro cittadino”. La didattica disciplinare è quindi interdipendente alle competenze trasversali e viceversa. Poter collaborare con i propri compagni di classe o di gruppo è quindi una pratica utile per migliorare l’apprendimento degli allievi. In questo lavoro di diploma si propone di lavorare seguendo il metodo del peer tutoring in generale, e in particolare il ciclo di apprendimento esperienziale, per migliorare l’apprendimento degli allievi nelle competenze orali di una classe di seconda media. I dati hanno mostrato che una progettazione didattica specifica, incentrata su questo approccio collaborativo, oltre che migliorare le competenze disciplinari, ha influito positivamente sulla competenza della collaborazione, indicando una possibile interconnessione tra potenziamento delle abilità sociali e miglioramento delle capacità comunicative nelle lingue seconde, aspetto che dovrà essere ulteriormente indagato in ricerche successive.

description: Is Dark Energy justified as an alternative to the cosmological constant $Λ$ in order to explain the acceleration of the cosmic expansion ? It turns out that a straightforward dimensional analysis of Einstein equation provides us with clear evidences that the geometrical nature of $Λ$ is the only viable source to this phenomenon, in addition of the application of Ockham's razor principle. This contribution is primarily a review of the main stream in the interpretation of $Λ$ because it is at the origin of such a research program.

description: Rationale & Objective: Clonal hematopoiesis of indeterminate potential (CHIP), defined by the age-related ontogenesis of expanded leukemogenic variants indicative of a genetically distinct clonal leukocyte population, is associated with risk of hematologic malignancy and cardiovascular disease. In experimental models, recapitulation of CHIP promotes kidney interstitial fibrosis with direct tissue infiltration of donor macrophages. We tested the hypothesis that CHIP is associated with kidney function decline in the general population. Study Design: Cohort study. Setting & Participants: 12,004 individuals from 3 community-based cohorts in the TOPMed Consortium. Exposure: CHIP status from whole-genome sequences obtained from DNA extracted from peripheral blood. Outcome: Risk of 30% decline in estimated glomerular filtration rate (eGFR) and percent eGFR decline per year during the follow-up period. Analytical Approach: Cox proportional hazards models for 30% eGFR decline end point and generalized estimating equations for annualized relative change in eGFR with meta-analysis. Study-specific estimates were combined using fixed-effect meta-analysis. Results: The median baseline eGFR was 84 mL/min/1.73 m2. The prevalence of CHIP was 6.6%, 9.0%, and 12.2% in persons aged 50-60, 60-70, and >70 years, respectively. Over a median follow-up period of 8 years, for the 30% eGFR outcome 205 events occurred among 1,002 CHIP carriers (2.1 events per 100 person-years) and 2,041 events in persons without CHIP (1.7 events per 100 person-years). In meta-analysis, CHIP was associated with greater risk of a 30% eGFR decline (17% [95% CI, 1%-36%] higher; P = 0.04). Differences were not observed between those with baseline eGFR above or below 60 mL/min/1.73 m2, of age above or below 60 years, or with or without diabetes. Limitations: Small number of participants with moderate-to-advanced kidney disease and restricted set of CHIP driver variants. Conclusions: We report an association between CHIP and eGFR decline in 3 general population cohorts without known kidney disease. Further studies are needed to investigate this novel condition and its potential impact among individuals with overt kidney disease.

description: Behavioral technicians (BT) within the field of applied behavior analysis may be at greater risk for experiencing burnout and stress due to the nature of their clients, job demands, and work environments. Burnout and stress may negatively impact BTs’ work performances, more specifically, their treatment integrity. Acceptance and Commitment Training (ACT) may be a useful tool to address the private events as well as the covert and overt behaviors associated with burnout and stress. The purpose of this study was to investigate the effects of an ACT intervention on improving treatment integrity and reducing work-related burnout and stress amongst BTs. Four BTs participated in an ACT workshop, and their treatment integrity as well as their burnout and stress levels were measured prior to and following the ACT workshop. Treatment integrity increased for all participants, suggesting that ACT-based interventions may be an effective approach to improving work performance (i.e., treatment integrity) amongst BTs who may experience workplace burnout and stress.

description: A plasma blob is modeled as consisting of two homogeneous spheres of equal radius and equal but opposite charge densities that can move relative to each other. Relative translational and rotational motion are considered separately. Magnetic effects from the current density caused by the relative motion are included. Magnetic interaction is seen to cause an inductive inertia. In the relative translation case the Coulomb attraction, approximately a linear force for small amplitudes, causes an oscillation. For a large number of particles the corresponding oscillation frequency will not be the Langmuir plasma frequency, because of the large inductive inertia. For rotation an external magnetic field is included and the energy and diamagnetism of the plasma in the model is calculated. Finally it is noted how the neglect of resistivity is motivated by the results.

description: Excerpts from the report: The combined gross volumes of marketing, farm-supply, and related-service cooperatives totaled $19.3 billion in 1963-64. This was an increase of 5 percent over the total gross volume of $18.3 billion in 1962-63. The total combined net volumes for 1963-64 amounted to $14.4 billion, an increase of 3.9 percent over the net volume figure of $13.8 billion for 1962-63. (The net volume figure does not include intercooperative business.) The total number of farmer cooperatives decreased by 60 from 8,907 in 1962-63 to 8,847 in 1963-64. The total number of memberships in farmer cooperatives decreased from 7,218,750 in 1962-63 to 7,079,500 in 1963-64, a decline of 1.9 percent.

description: We present the results of extensive simulations regarding the critical behavior at the endpoint of the Roberge-Weiss transition for N_f = 2 QCD. We confirm early evidence, presented in arXiv:0909.0254, according to which the Roberge-Weiss endpoint is first order in the limit of large or small quark masses, and second order for intermediate masses. A systematic study of the transition strength as a function of the quark mass in the first order regions, permits us to estimate the tricritical values of the quark mass separating the second order region from the first order ones.

description: La motivazione è una componente molto importante nella vita scolastica di un bambino. Per apprendere in maniera proficua, gli allievi devono avere la curiosità e l’interesse adeguati. Grazie a questi aspetti i bambini possono raggiungere la volontà di conoscere nuovi concetti. I docenti, fin dai primi anni di scuola hanno quindi il compito di sviluppare la motivazione negli allievi così da costruire un rapporto positivo tra il bambino e la scuola. Nel seguente lavoro di ricerca si analizzerà il rapporto che gli allievi hanno con la matematica, in un contesto classe in cui la motivazione è povera. Attraverso un percorso si è cercato di lavorare sulle passioni degli allievi con la volontà di integrare gli stessi nell’apprendimento della matematica. Questo percorso ha permesso di coinvolgere e valorizzare ogni allievo così d’aumentare la loro autostima e la loro autoefficacia. La raccolta dati è avvenuta tramite due questionari (uno iniziale e uno finale) e l’osservazione in classe. Relatrice: Monica Panero.
Exploring occupational stress and the perceptions of a canine-assisted intervention in law-enforcement personnel : a case study
Creators: name: Green, Freya Loren Louise

description: Despite the increasing popularity of canine-assisted interventions (CAIs) across a variety of contexts, and the demonstrated efficacy CAIs have on stress reduction, there is a paucity of literature that has examined the effects of such programs within the context of law-enforcement. Policing is known to be an environment in which personnel experience elevates occupational stress (Ménard & Arter, 2013; Ranta & Sud, 2008). As stress can be influential in the overall well-being of members and their ability to serve the public, it is important to establish and integrate effective stress-reduction strategies within detachment settings. To address these needs, this qualitative study explored the experiences of stress within members, and a CAI integrated within an urban RCMP detachment. Eight RCMP members (75% female, Mage = 49.21, SD = 6.12) from an urban RCMP detachment situated in the downtown core of a small city, were interviewed. The interview focused on topics including members’ experiences of stress within the workplace, their perceptions of the effects of stress, resources and sources of support, and their experiences of a weekly CAI within their detachment. Results indicate that organizational stressors were identified more often than operational stressors; that members most commonly report stress making them more irritable and affecting their sleep; and that the most commonly reported coping mechanism and resource are exercise and medical services, respectively. In discussing the CAI, participants were overwhelmingly positive in their experiences of the program, and demonstrated support for having CAIs within the detachment setting. Discussion of the impact of the sessions demonstrated that participants found that the program served as a break from work, relieved their stress, improved their mood, and helped them to change perspectives. Participants also identified the role of the dogs within the program, which included their role as a social entity. The findings from the current study contribute to better understanding of the lived experiences of stress within RCMP members, and of CAIs within an applied setting.

description: BACKGROUND: In response to the COVID-19 pandemic, public health measures, including stay-at-home orders, were widely instituted in the United States by March 2020. However, few studies have evaluated the impact of these measures on continuity of care among older adults living with chronic diseases. METHODS: Beginning in June 2020, participants of the national Women's Health Initiative (WHI) (N = 64 061) were surveyed on the impact of the pandemic on various aspects of their health and well-being since March 2020, including access to care appointments, medications, and caregivers. Responses received by November 2020 (response rate = 77.6%) were tabulated and stratified by prevalent chronic diseases, including hypertension, type 2 diabetes, and cardiovascular disease (CVD). RESULTS: Among 49 695 respondents (mean age = 83.6 years), 70.2% had a history of hypertension, 21.8% had diabetes, and 18.9% had CVD. Half of the respondents reported being very concerned about the pandemic, and 24.5% decided against seeking medical care to avoid COVID-19 exposure. A quarter reported difficulties with getting routine care, and 45.5% had in-person appointments converted to telemedicine formats; many reported canceled (27.8%) or rescheduled (37.7%) appointments. Among those taking prescribed medication (88.0%), 9.7% reported changing their method of obtaining medications. Those living with and without chronic diseases generally reported similar changes in care and medication access. CONCLUSIONS: Early in the pandemic, many older women avoided medical care or adapted to new ways of receiving care and medications. Therefore, optimizing alternative services, like telemedicine, should be prioritized to ensure that older women continue to receive quality care during public health emergencies.

description: Excerpts from the report: A 1964-65 survey of marketing, farm-supply, and related-service cooperatives showed a continuing upward trend in total business volume, a slight increase in number of memberships, and a decline in number of organizations during July 1, 1964- June 30, 1965. Total gross business volume (includes intercooperative business) handled by these cooperatives amounted to $19.6 billion. This was an increase of 1.9 percent over the $19.3 billion reported in the previous fiscal year. Total net business, after adjusting the gross figure for business done between cooperatives, amounted to $14.7 billion. This was an increase of 2.7 percent over the $14.4 billion net in 1963-64. The total number of farmer cooperatives decreased from 8,847 in 1963-64 to 8,583 in 1964-65, a net decrease of 264 associations. Cooperative memberships totaled 7,082,010 in 1964-65, a slight increase over the 7,079,500 memberships reported for 1963-64. While the membership figure remained relatively stable during this reporting period, the long-term trend has been a decline in cooperative memberships due to the decreasing number of farmers in the United States.

description: Consider a family of sets and a single set, called the query set. How can one quickly find a member of the family which has a maximal intersection with the query set? Time constraints on the query and on a possible preprocessing of the set family make this problem challenging. Such maximal intersection queries arise in a wide range of applications, including web search, recommendation systems, and distributing on-line advertisements. In general, maximal intersection queries are computationally expensive. We investigate two well-motivated distributions over all families of sets and propose an algorithm for each of them. We show that with very high probability an almost optimal solution is found in time which is logarithmic in the size of the family. Moreover, we point out a threshold phenomenon on the probabilities of intersecting sets in each of our two input models which leads to the efficient algorithms mentioned above.

description: Early warning indicators based on critical slowing down have been suggested as a model-independent and low-cost tool to anticipate the (re)emergence of infectious diseases. We studied whether such indicators could reliably have anticipated the second COVID-19 wave in European countries. Contrary to theoretical predictions, we found that characteristic early warning indicators generally decreased rather than increased prior to the second wave. A model explains this unexpected finding as a result of transient dynamics and the multiple timescales of relaxation during a non-stationary epidemic. Particularly, if an epidemic that seems initially contained after a first wave does not fully settle to its new quasi-equilibrium prior to changing circumstances or conditions that force a second wave, then indicators will show a decreasing rather than an increasing trend as a result of the persistent transient trajectory of the first wave. Our simulations show that this lack of timescale separation was to be expected during the second European epidemic wave of COVID-19. Overall, our results emphasize that the theory of critical slowing down applies only when the external forcing of the system across a critical point is slow relative to the internal system dynamics.
title: Symmetry-based stability theory in fluid mechanics
Creators: name: Gebler, Tim
Publisher: name: UNSPECIFIED
Year: 2023

description: The present work deals with the stability theory of fluid flows. The central subject is the question under which circumstances a flow becomes unstable. Instabilities are a frequent trigger of laminar-turbulent transitions. Stability theory helps to explain the emergence of structures, e.g. wave-like perturbation patterns. In this context, the use of Lie symmetries allows the classification of existing and the construction of new solutions within the framework of linear stability theory. In addition, a new nonlinear eigenvalue problem (NEVP) is presented, whose derivation is completely based on Lie symmetries. In classical linear stability theory, a normal ansatz is used for perturbations. Another ansatz that has been shown in early work is the Kelvin mode ansatz. In the work of Nold and Oberlack (2013) and Nold et al. (2015) it was shown that these ansätze can be traced back to the Lie symmetries of the linearized perturbation equations. Interestingly, knowledge of the symmetries also allows for the construction of new ansatz functions that go beyond the known ansätze. For a plane rotational shear flow, in addition to the normal mode ansatz, an algebraic mode ansatz with algebraic behavior in time t^s (eigenvalue s) can be constructed. The flow is stable according to Rayleigh's inflection point criterion, which is also confirmed by the algebraic mode ansatz. Furthermore, exact solutions of the eigenfunctions can be found and new stable modes can be determined by asymptotic methods. Thereby, spiral-like structures of the vorticity can be recognized, which propagate in the region with time. Another key result of this work is the formulation and solution of an NEVP based on the Lie symmetries of the Euler equation. It can is shown that an NEVP can be formulated for a class of flows with a constant velocity gradient. These include, for example, linear shear flows, strained flows, and rotating flows. The NEVP for linear shear flows shows a relation to experimental data from turbulent shear flows. It can be theoretically shown that the turbulent kinetic energy scales exponentially with the eigenvalue of the NEVP. The eigenvalue is determined numerically using a parallel spectral solver. Initially, nonlinear terms are neglected. The determined eigenvalues are in the range of known literature values for turbulent shear flows. Furthermore, the NEVPs for plane flows with pure rotation and pure strain are solved. It is shown that the flow is invariant to rotation, while oscillatory eigenfunctions are found in the case of strain. In addition, an algorithm to solve the NEVP including the nonlinear terms is presented. The results allow an exciting insight into a new stability theory and form the basis for further investigation and understanding of the full nonlinear dynamics of the fluid flows based on the NEVP.

description: The dynamics of symmetry breaking responsible for lifting the degeneracy of the Landau levels in the integer quantum Hall effect in graphene is studied in a low-energy model with the Coulomb interaction. The gap equation for Dirac quasiparticles is analyzed for both the lowest and higher Landau levels, taking into account the Landau levels mixing. It is shown that the characteristic feature of the long-range Coulomb interaction is the decrease of the gap parameters with increasing the Landau level index $n$ ("running" gaps). The renormalization (running) of the Fermi velocity as a function of $n$ is also studied. The solutions of the gap equation reproduce correctly the experimentally observed integer quantum Hall plateaus in graphene in strong magnetic fields.

description: Background: Despite a multifactorial approach being taken for the evaluation of bull semen quality in many animal breeding centres worldwide, reliable prediction of bull fertility is still a challenge. Recently, attention has turned to molecular mechanisms, which could uncover potential biomarkers of fertility. One of these mechanisms is DNA methylation, which together with other epigenetic mechanisms is essential for the fertilising sperm to drive normal embryo development and establish a viable pregnancy. In this study, we hypothesised that bull sperm DNA methylation patterns are related to bull fertility. We therefore investigated DNA methylation patterns from bulls used in artifcial insemination with contrasting fertility scores. Results: The DNA methylation patterns were obtained by reduced representative bisulphite sequencing from 10 high-fertility bulls and 10 low-fertility bulls, having average fertility scores of −6.6 and + 6.5%, respectively (mean of the population was zero). Hierarchical clustering analysis did not distinguish bulls based on fertility but did highlight individual diferences. Despite this, using stringent criteria (DNA methylation diference≥35% and a q-value <0.001), we identifed 661 diferently methylated cytosines DMCs). DMCs were preferentially located in intergenic regions, introns, gene downstream regions, repetitive elements, open sea, shores and shelves of CpG islands. We also identifed 10 diferently methylated regions, covered by 7 unique genes (SFRP1, STXBP4, BCR, PSMG4, ARSG, ATP11A, RXRA), which are involved in spermatogenesis and early embryonic development. Conclusion: This study demonstrated that at specifc CpG sites, sperm DNA methylation status is related to bull fertility, and identifed seven diferently methylated genes in sperm of subfertile bulls that may lead to altered gene expression and potentially infuence embryo development.
