title: Neuroestrogens in the mouse hypothalamus: synthesis, regulation, and behavioural implications using novel ex vivo slice culture and in vivo models
Creators: name: Dovey, Janine L.
Publisher: name: University of Reading
Year: 2024

description: 17β-oestradiol significantly influences several physiological processes, many of which are linked to the central nervous system. Oestrogen receptors (ERs) are widespread thoughout the brain, including the social behaviour network (SBN): a conserved set of hypothalamic and limbic nuclei underlying sexually dimorphic social behaviours. Previous research has shown confirmed the brain’s capacity to synthesise its own oestrogens, termed neuroestrogens, albeit with a focus on the hippocampus. The hypothalamus has garnered less attention in this regard. Despite evidence that hypothalamic aromatase is active, direct quantification of neuroestrogens in this region or in the nodes of the social behaviour network have not been performed. This highlights a significant gap in knowledge, as neuroestrogens bear the potential to serve as critical modulators within the SBN. Furthermore, how neuroestrogen synthesis is regulated in the female in the face of abundant gonadal oestrogens is unknown.
To address this gap, we developed a novel method to measure neuroestrogens within the SBN, allowing us to understand how neuroestrogen synthesis is regulated in two major hypothalamic SBN nuclei. We have demonstrated that neuroestrogens were still measurable in ovariectomised mice, underscoring the autonomous steroidogenic capacity of the SBN. We also demonstrated the presence of a novel, androgen-dependent regulatory pathway that regulates neuroestrogen synthesis in the female medial preoptic area (mPOA) but not in the ventromedial hypothalamus (VMH), suggesting nuclei-specific regulation of neuroestrogen production. We have demonstrated that disruption of this pathway in vivo has a subtle anxiogenic effect, correlated with dendritic atrophy and reduced spine density in the female mPOA, akin to that observed in ovariectomised mice. Finally, we used a unique conditional aromatase knockout mouse to understand how neuroestrogen synthesis within discrete hypothalamic SBN nuclei contributes to behaviour. In doing this, we showed hypothalamo-limbic aromatase regulates anxiety but not sex or aggressive behaviours in the male mouse.

Hannah graduated in 2013 from the National College of Art and Design, Dublin and is now studying photography at Griffith College Dublin. She works mainly in photography but also in sculpture and installation. She has exhibited her work on a number of occasions in Dublin, including a solo show at the Hendrons Collider gallery space. The image Sharper Edge came about through observing abstract forms in everyday objects. The picture was taken of a broken glass block window in a converted factory. As the block was hollow, the break resulted in a natural layered effect. This effect was not necessarily obvious to the naked eye when seen in 3D however when taken digitally in a photographic 2D format, the result was more surreal.

Sexual Assault and Advance Consent: A Feminist Judgment in R v JA
Creators: name: Koshan, Jennifer
Publisher: name: feminists@law
Year: 2015

description: This is the audio recording of a seminar given at the Kent Centre for Law, Gender and Sexuality, University of Kent, on 12 November 2015. The paper discusses a draft feminist judgment in R v JA [2011] SCC 28 (Supreme Court of Canada), a spousal sexual assault case involving the issue of whether parties can consent in advance to sexual activity that will occur while they are asleep or unconscious. The JA ruling has generated critique and debate amongst feminists and law and sexuality scholars that pits women's security interests against their sexual autonomy. The judgment endeavours to analyse whether it is possible to adopt an approach to advance consent that advances both of these interests, or whether they are ultimately irreconcilable. In doing so, it explores the proposal of Justice Fish, writing in dissent at the Supreme Court of Canada, that an appropriate balance might be that taken under s 75(2)(d) of the UK's Sexual Offences Act 2003, which creates a presumption against advance consent but not an absolute bar to arguing it. The author is a member of the Women's Court of Canada project, the first feminist judgment re-writing project internationally, and she also speaks to the potential value as well as challenges of feminist judgment writing.

description: Speeding up development may produce technical debt, i.e., not-quite-right code for which the effort to make it right increases with time as a sort of interest. Developers may be aware of the debt as they admit it in their code comments. Literature reports that such a self-admitted technical debt survives for a long time in a program, but it is not yet clear its impact on the quality of the code in the long term. We argue that self-admitted technical debt contains a number of different weaknesses that may affect the security of a program. Therefore, the longer a debt is not paid back the higher is the risk that the weaknesses can be exploited. To discuss our claim and rise the developers' awareness of the vulnerability of the self-admitted technical debt that is not paid back, we explore the self-admitted technical debt in the Chromium C-code to detect any known weaknesses. In this preliminary study, we first mine the Common Weakness Enumeration repository to define heuristics for the automatic detection and fix of weak code. Then, we parse the C-code to find self-admitted technical debt and the code block it refers to. Finally, we use the heuristics to find weak code snippets associated to self-admitted technical debt and recommend their potential mitigation to developers. Such knowledge can be used to prioritize self-admitted technical debt for repair. A prototype has been developed and applied to the Chromium code. Initial findings report that 55\% of self-admitted technical debt code contains weak code of 14 different types.

description: Multijunction solar cells are usually grown on Ge substrates. This implies several disadvantages that hinder the performance of the whole multijunction and limit their possible applications. The drawbacks caused by the substrate are: heavier devices, higher operation temperatures, lower performance and lack of photon confinement. In this work we propose thinning the substrate as a valid solution to the aforementioned challenges. The influence of the substrate thickness on the Ge subcell performance inside a multijunction is simulated using 2D TCAD tools. Simulation results point to the back surface recombination as the key parameter to enhance the development of thinned Ge subcells. Ge substrates have been thinned down, achieving 115μm thick samples. Finally, solar cells have been manufactured out of the thinned substrates proving a limited degradation and showing the feasibility of this process to manufacture Ge subcells thinned down up to 115μm.

description: The intensities of the hydrogen Balmer lines of solar-like stars are investigated for stellar chromospheric activity by using the co-source spectral data of the LAMOST Low-Resolution Spectroscopic Survey (LRS) and Medium-Resolution Spectroscopic Survey (MRS). The Balmer H$α$, H$β$, H$γ$, and H$δ$ lines in the LRS data and the H$α$ line in the MRS data are analyzed. The absolute flux indexes, defined as the ratios of the absolute fluxes at the centers of the Balmer lines to the stellar bolometric flux, are employed to indicate the intensity magnitudes of the Balmer lines in response to stellar activity. The H$α$ indexes derived from the LRS data and the MRS data, respectively, are calibrated to be quantitatively consistent with each other. It is found that, as the H$α$ index increases, the H$β$, H$γ$, and H$δ$ indexes first present trend of increasing and then decreasing, and finally increase synchronously with the H$α$ index. The distributions of the Balmer line indexes also reveal the three distinct stages of stellar activity (normal stage, intense stage, and extremely intense stage), in which the extremely intense stage is characterized by the synchronous growth of the indexes of the four Balmer lines. The different behaviors of the H$β$, H$γ$, and H$δ$ lines from that of the H$α$ line can be interpreted by the different mechanisms by which the line-core intensities are formed, and the three distinct activity stages imply the very different magnetic field environments and physical conditions of solar-like stars.

description: Determining the principal energy pathways for allosteric communication in biomolecules, that occur as a result of thermal motion, remains challenging due to the intrinsic complexity of the systems involved. Graph theory provides an approach for making sense of such complexity, where allosteric proteins can be represented as networks of amino acids. In this work, we establish the eigenvector centrality metric in terms of the mutual information, as a mean of elucidating the allosteric mechanism that regulates the enzymatic activity of proteins. Moreover, we propose a strategy to characterize the range of the physical interactions that underlie the allosteric process. In particular, the well known enzyme, imidazol glycerol phosphate synthase (IGPS), is utilized to test the proposed methodology. The eigenvector centrality measurement successfully describes the allosteric pathways of IGPS, and allows to pinpoint key amino acids in terms of their relevance in the momentum transfer process. The resulting insight can be utilized for refining the control of IGPS activity, widening the scope for its engineering. Furthermore, we propose a new centrality metric quantifying the relevance of the surroundings of each residue. In addition, the proposed technique is validated against experimental solution NMR measurements yielding fully consistent results. Overall, the methodologies proposed in the present work constitute a powerful and cost effective strategy to gain insight on the allosteric mechanism of proteins.

description: Recent research has focused on $\ell_1$ penalized least squares (Lasso) estimators for high-dimensional linear regressions in which the number of covariates $p$ is considerably larger than the sample size $n$. However, few studies have examined the properties of the estimators when the errors and/or the covariates are serially dependent. In this study, we investigate the theoretical properties of the Lasso estimator for a linear regression with a random design and weak sparsity under serially dependent and/or nonsubGaussian errors and covariates. In contrast to the traditional case, in which the errors are independent and identically distributed and have finite exponential moments, we show that $p$ can be at most a power of $n$ if the errors have only finite polynomial moments. In addition, the rate of convergence becomes slower owing to the serial dependence in the errors and the covariates. We also consider the sign consistency of the model selection using the Lasso estimator when there are serial correlations in the errors or the covariates, or both. Adopting the framework of a functional dependence measure, we describe how the rates of convergence and the selection consistency of the estimators depend on the dependence measures and moment conditions of the errors and the covariates. Simulation results show that a Lasso regression can be significantly more powerful than a mixed-frequency data sampling regression (MIDAS) and a Dantzig selector in the presence of irrelevant variables. We apply the results obtained for the Lasso method to nowcasting with mixed-frequency data, in which serially correlated errors and a large number of covariates are common. The empirical results show that the Lasso procedure outperforms the MIDAS regression and the autoregressive model with exogenous variables in terms of both forecasting and nowcasting.

description: We show that many graphs naturally associated to a connected, compact, orientable surface are hierarchically hyperbolic spaces in the sense of Behrstock, Hagen and Sisto. They also automatically have the coarse median property defined by Bowditch. Consequences for such graphs include a distance formula analogous to Masur and Minsky's distance formula for the mapping class group, an upper bound on the maximal dimension of quasiflats, and the existence of a quadratic isoperimetric inequality. The hierarchically hyperbolic structure also gives rise to a simple criterion for when such graphs are Gromov hyperbolic.

description: In this paper we investigate the asymptotic behavior of the colored Jones polynomials and the Turaev-Viro invariants for the figure eight knot. More precisely, we consider the $M$-th colored Jones polynomials evaluated at $(N+1/2)$-th root of unity with a fixed limiting ratio, $s$, of $M$ and $(N+1/2)$. We find out the asymptotic expansion formula (AEF) of the colored Jones polynomials of the figure eight knot with $s$ close to $1$. Nonetheless, we show that the exponential growth rate of the colored Jones polynomials of the figure eight knot with $s$ close to $1/2$ is strictly less than those with $s$ close to $1$. It is known that the Turaev Viro invariant of the figure eight knot can be expressed in terms of a sum of its colored Jones polynomials. Our results show that this sum is asymptotically equal to the sum of the terms with $s$ close to 1. As an application of the asymptotic behavior of the colored Jones polynomials, we obtain the asymptotic expansion formula for the Turaev-Viro invariants of the figure eight knot. Finally, we suggest a possible generalization of our approach so as to relate the AEF for the colored Jones polynomials and the AEF for the Turaev-Viro invariants for general hyperbolic knots.

description: We formulate some refinements of Goldbach's conjectures based on heuristic arguments and numerical data. For instance, any even number greater than 4 is conjectured to be a sum of two primes with one prime being 3 mod 4. In general, for fixed $m$ and $a, b$ coprime to $m$, any positive even $n \equiv a + b \bmod m$ outside of a finite exceptional set is expected to be a sum of two primes $p$ and $q$ with $p \equiv a \bmod m$, $q \equiv b \bmod m$. We make conjectures about the growth of these exceptional sets.

description: Background: To increase the global impact of health promotion related to non-communicable diseases, health professionals need evidence-based core competencies in health assessment and lifestyle behavior change. Assessment of health promotion curricula by health professional programs is a first step. Such program assessment is a means of 1. demonstrating collective commitment across health professionals to prevent non-communicable diseases; 2. addressing the knowledge translation gap between what is known about non-communicable diseases and their risk factors consistent with ‘best’ practice; and, 3. establishing core health-based competencies in the entry-level curricula of established health professions. Discussion: Consistent with the World Health Organization’s definition of health (i.e., physical, emotional and social wellbeing) and the Ottawa Charter, health promotion competencies are those that support health rather than reduce signs and symptoms primarily. A process algorithm to guide the implementation of health promotion competencies by health professionals is described. The algorithm outlines steps from the initial assessment of a patient’s/client’s health and the indications for health behavior change, to the determination of whether that health professional assumes primary responsibility for implementing health behavior change interventions or refers the patient/client to others. An evidence-based template for assessment of the health promotion curriculum content of health professional education programs is outlined. It includes clinically-relevant behavior change theory; health assessment/examination tools; and health behavior change strategies/interventions that can be readily integrated into health professionals’ practices. Summary: Assessment of the curricula in health professional education programs with respect to health promotion competencies is a compelling and potentially cost-effective initial means of preventing and reversing non-communicable diseases. Learning evidence-based health promotion competencies within an inter-professional context would help students maximize use of non-pharmacologic/non-surgical approaches and the contribution of each member of the health team. Such a unified approach would lead patients/clients to expect their health professionals to assess their health and lifestyle practices, and empower and support them in achieving lifelong health. Benefits of such curriculum assessment include a basis for reflection and discussion within and across health professional programs that could impact the epidemic of non-communicable diseases globally, through inter-professional education and evidence-based practice related to health promotion.

description: Soft microrobots based on photoresponsive materials and controlled by light fields can generate a variety of different gaits. This inherent flexibility can be exploited to maximize their locomotion performance in a given environment and used to adapt them to changing conditions. Albeit, because of the lack of accurate locomotion models, and given the intrinsic variability among microrobots, analytical control design is not possible. Common data-driven approaches, on the other hand, require running prohibitive numbers of experiments and lead to very sample-specific results. Here we propose a probabilistic learning approach for light-controlled soft microrobots based on Bayesian Optimization (BO) and Gaussian Processes (GPs). The proposed approach results in a learning scheme that is data-efficient, enabling gait optimization with a limited experimental budget, and robust against differences among microrobot samples. These features are obtained by designing the learning scheme through the comparison of different GP priors and BO settings on a semi-synthetic data set. The developed learning scheme is validated in microrobot experiments, resulting in a 115% improvement in a microrobot's locomotion performance with an experimental budget of only 20 tests. These encouraging results lead the way toward self-adaptive microrobotic systems based on light-controlled soft microrobots and probabilistic learning control.

description: We study bicolored configurations of points in the Euclidean $n$-space that are constrained to remain either inside or outside a fixed Euclidean $m$-subspace, with $n - m \ge 2$. We define a higher-codimensional variant of the Swiss-Cheese operad, called the complementarily constrained disks operad $\mathsf{CD}_{mn}$, associated to such configurations. The operad $\mathsf{CD}_{mn}$ is weakly equivalent to the operad of locally constant factorization algebras on the stratified space $\{\mathbb{R}^{m} \subset \mathbb{R}^{n}\}$. We prove that this operad is formal over $\mathbb{R}$.

Body image and its impact in selected groups of men
Creators: name: O'Sullivan, Grant
Publisher: name: Swinburne
Year: 2024

description: This thesis examined the relationship between body image and Psychological Distress in three groups of men: bodybuilders, elite Australian Rules football players and a control group who did not participate in any elite level sports. The main objective was to examine the extent that body form and body function are related to Muscle Dysmorphia, Body Esteem and Psychological Distress in groups where physique is important for either body form or body function reasons. The results of a quantitative study showed that (a) having a distorted self-perception of being less muscular was associated with more negative body feelings; (b) body dissatisfaction was related to body perception distortion; and (c) the control group, who expressed less Muscle Dysmorphia than the footballers and bodybuilders, had generally negative body images, whereas the footballers and bodybuilders had both positive and negative aspects incorporated into their body images. Surprisingly, no significant relationships between the other measures of body image (body dissatisfaction, body perception distortion and Body Esteem) and Muscle Dysmorphia were found. However, a further qualitative study using thematic analysis suggested that men from each of the participant groups did in fact have some symptoms of Muscle Dysmorphia, and that there were psychological and behavioural consequences of this, but that a masculine culture within Australian Rules football and the psycho-protective effect of exercise appeared to have some prophylactic effect. Overall, these results suggest that, in groups of men who train for either body form or body function reasons, the relationship between perceived body image and how it is expressed in behavioural, emotional and cognitive terms is complex.

Bodies, Buses and Permits: Palestinians Navigating Care

description: All Palestinian bodies, male and female, are subject to and targeted by the occupying state. Drawing on participatory observation conducted in the West Bank, this essay focuses on how gender and occupation intersect in men’s access to care and seeks to realign feminist practice to examine the ways in which all bodies are subject to the intersections of gender, race, class and power. It shows the lived realities of Palestinian everyday life that are occluded when one considers only the “legal formalities” Israel has put in place, which seem to allow for access to certain spaces for sick bodies, but in fact hinder or deny every attempt to do so. Finally, I conclude with some reflections on how the current Boycott, Divestment and Sanctions (BDS) movement is one means of addressing the forms of power exercised over Palestinian bodies living under occupation.

description: We investigate multiple testing and variable selection using the Least Angle Regression (LARS) algorithm in high dimensions under the assumption of Gaussian noise. LARS is known to produce a piecewise affine solution path with change points referred to as the knots of the LARS path. The key to our results is an expression in closed form of the exact joint law of a $K$-tuple of knots conditional on the variables selected by LARS, namely the so-called post-selection joint law of the LARS knots. Numerical experiments demonstrate the perfect fit of our findings. This paper makes three main contributions. First, we build testing procedures on variables entering the model along the LARS path in the general design case when the noise level can be unknown. These testing procedures are referred to as the Generalized $t$-Spacing tests (GtSt) and we prove that they have an exact non-asymptotic level (i.e., the Type I error is exactly controlled). This extends work of (Taylor et al., 2014) where the spacing test works for consecutive knots and known variance. Second, we introduce a new exact multiple false negatives test after model selection in the general design case when the noise level may be unknown. We prove that this testing procedure has exact non-asymptotic level for general design and unknown noise level. Third, we give an exact control of the false discovery rate under orthogonal design assumption. Monte Carlo simulations and a real data experiment are provided to illustrate our results in this case. Of independent interest, we introduce an equivalent formulation of the LARS algorithm based on a recursive function.

description: In this study, a multiple kernel learning support vector machine algorithm is proposed for the identification of EEG signals including mental and cognitive tasks, which is a key component in EEG-based brain computer interface (BCI) systems. The presented BCI approach included three stages: (1) a pre-processing step was performed to improve the general signal quality of the EEG; (2) the features were chosen, including wavelet packet entropy and Granger causality, respectively; (3) a multiple kernel learning support vector machine (MKL-SVM) based on a gradient descent optimization algorithm was investigated to classify EEG signals, in which the kernel was defined as a linear combination of polynomial kernels and radial basis function kernels. Experimental results showed that the proposed method provided better classification performance compared with the SVM based on a single kernel. For mental tasks, the average accuracies for 2-class, 3-class, 4-class, and 5-class classifications were 99.20%, 81.25%, 76.76%, and 75.25% respectively. Comparing stroke patients with healthy controls using the proposed algorithm, we achieved the average classification accuracies of 89.24% and 80.33% for 0-back and 1-back tasks respectively. Our results indicate that the proposed approach is promising for implementing human-computer interaction (HCI), especially for mental task classification and identifying suitable brain impairment candidates.

description: Previous studies have related surface temperature maps, obtained with the Doppler imaging (DI) technique, of LQ Hya with long-term photometry. We compare surface magnetic field maps, obtained with the Zeeman Doppler imaging (ZDI) technique, with contemporaneous photometry, with the aim of quantifying the star's magnetic cycle characteristics. We inverted Stokes IV spectropolarimetry into magnetic field and surface brightness maps using a tomographic inversion code that models high signal-to-noise ratio mean line profiles produced by the least squares deconvolution (LSD) technique. The magnetic field and surface brightness maps reveal similar patterns to previous DI and ZDI studies: non-axisymmetric polar magnetic field structure, void of fields at mid-latitudes, and a complex structure in the equatorial regions. There is a weak but clear tendency of the polar structures to be linked with strong radial field and the equatorial ones with the azimuthal. We find a polarity reversal in the radial field between 2016 and 2017 coincident with an activity minimum seen in the long-term photometry. The inverted field strengths cannot easily be related with the observed spottedness, but we find that they are partially connected with the retrieved field complexity. Comparing to global magnetoconvection models for rapidly rotating young Suns, this field topology and dominance of the poloidal field component could be explained by a turbulent dynamo, where differential rotation does not play a major role (so called alpha^2 Omega or alpha^2 dynamos), and axi- and non-axisymmetric modes are excited simultaneously. The complex equatorial magnetic field structure could arise from the twisted (helical) wreaths often seen in these simulations, while the polar feature would be connected to the mostly poloidal non-axisymmetric component having a smooth spatial structure.

description: We consider a system of fermions with local interactions on a lattice (Hubbard model) and apply a novel extension of the Laplace's method (saddle-point approximation) for evaluating the corresponding partition function. There, we introduce dual free bosonic fields, with a propagator corresponding to an effective (renormalized) interaction with Maki-Thompson and Aslamazov-Larkin type corrections and beyond, and demonstrate that the superconducting pairing originates as an instability of the effective interaction. We derive the corresponding Bethe-Salpeter equation (instability criterion) and show that the interaction enters the equation only in its effective form to all orders, including the exchange part of the self-energy. An important implication of this result is that the effective interaction always remains finite, even at phase-transition points, directly contradicting the often used assumption of linear relationship between the interaction and susceptibility, established within the random-phase approximation. By analyzing the Bethe-Salpeter equation in the context of unconventional superconductivity, we find that the presence of a flat band close the Fermi level, found in materials such as twisted bilayer graphene, has a twofold favorable impact persisting beyond the weak-coupling approximation: a reduced kinetic energy cost of the gap formation and an increased anisotropy of the effective interaction, favoring a momentum dependent order parameter.

Nielsen Equivalence in Fuchsian groups
Creators: name: Lustig, Martin
name: Moriah, Yoav
Publisher: name: arXiv
Year: 2019
Subjects: subject: Geometric Topology (math.GT)
subject: FOS: Mathematics

description: In this paper we give a complete classification of minimal generating systems in a very general class of Fuchsian groups G. This class includes for example any G which has at least seven non-conjugate cyclic subgroups of order greater than 2. In particular, the well known problematic cases where G has characteristic exponents equal to 2 are not excluded. We classify generating systems up to Nielsen equivalence; this notion is strongly related to Heegaard splittings of 3-manifolds. The results of this paper provide in particular the tools for a rather general extension of previous work of the authors and others, on the isotopy classification of such splittings in Seifert fibered spaces.

description: This work studies an explicit embedding of the set of probability measures into a Hilbert space, defined using optimal transport maps from a reference probability density. This embedding linearizes to some extent the 2-Wasserstein space, and enables the direct use of generic supervised and unsupervised learning algorithms on measure data. Our main result is that the embedding is (bi-)Hölder continuous, when the reference density is uniform over a convex set, and can be equivalently phrased as a dimension-independent Hölder-stability results for optimal transport maps.

Chronic kidney disease and support provided by home care services: a systematic review

description: Background: Chronic diseases, such as chronic kidney disease (CKD), are growing in incidence and prevalence, in part due to an aging population. Support provided through home care services may be useful in attaining a more efficient and higher quality care for CKD patients. Methods: A systematic review was performed to identify studies examining home care interventions among adult CKD patients incorporating all outcomes. Studies examining home care services as an alternative to acute, post-acute or hospice care and those for long-term maintenance in patients’ homes were included. Studies with only a home training intervention and those without an applied research component were excluded. Results: Seventeen studies (10 cohort, 4 non-comparative, 2 cross-sectional, 1 randomized) examined the support provided by home care services in 15,058 CKD patients. Fourteen studies included peritoneal dialysis (PD), two incorporated hemodialysis (HD) and one included both PD and HD patients in their treatment groups. Sixteen studies focused on the dialysis phase of care in their study samples and one study included information from both the dialysis and pre-dialysis phases of care. Study settings included nine single hospital/dialysis centers and three regional/metropolitan areas and five were at the national level. Studies primarily focused on nurse assisted home care patients and mostly examined PD related clinical outcomes. In PD studies with comparators, peritonitis risks and technique survival rates were similar across home care assisted patients and comparators. The risk of mortality, however, was higher for home care assisted PD patients. While most studies adjusted for age and comorbidities, information about multidimensional prognostic indices that take into account physical, psychological, cognitive, functional and social factors among CKD patients was not easily available. Conclusions: Most studies focused on nurse assisted home care patients on dialysis. The majority were single site studies incorporating small patient populations. There are gaps in the literature regarding the utility of providing home care to CKD patients and the impact this has on healthcare resources.

description: Repairnator is a bot. It constantly monitors software bugs discovered during continuous integration of open-source software and tries to fix them automatically. If it succeeds in synthesizing a valid patch, Repairnator proposes the patch to the human developers, disguised under a fake human identity. To date, Repairnator has been able to producepatches that were accepted by the human developers and permanently merged into the code base. This is a milestone for human-competitiveness in software engineering research on automatic program repair.

description: Cylindrical contact homology is a comparatively simple incarnation of symplectic field theory whose existence and invariance under suitable hypotheses was recently established by Hutchings and Nelson. We study this invariant for a general Brieskorn 3-manifold $Σ(a_1,\ldots, a_n)$, and give a complete description of the cylindrical contact homology for this 3-manifold equipped with its natural contact structure, for any $a_j$ satisfying $\frac{1}{a_1} + \cdots + \frac{1}{a_n} < n-2$.
