description: Let $\cM_{g,n}$ be the moduli space of Riemann surfaces of genus $g$ with $n$ punctures. From a complex perspective, moduli space is hyperbolic. For example, $\cM_{g,n}$ is abundantly populated by immersed holomorphic disks of constant curvature -1 in the Teichmüller (=Kobayashi) metric. When $r=\dim_{\cx} \cM_{g,n}$ is greater than one, however, $\cM_{g,n}$ carries no complete metric of bounded negative curvature. Instead, Dehn twists give chains of subgroups $\zed^r \subset π_1(\cM_{g,n})$ reminiscent of flats in symmetric spaces of rank $r>1$. In this paper we introduce a new Kähler metric on moduli space that exhibits its hyperbolic tendencies in a form compatible with higher rank.

description: This paper investigates the non-linear self-interaction of quadrupole gravitational waves generated by an isolated system. The vacuum Einstein field equations are integrated in the region exterior to the system by means of a post-Minkowskian algorithm. Specializing in the quadrupole-quadrupole interaction (at the quadratic non-linear order), we recover the known results concerning the non-local modification of the ADM mass-energy of the system accounting for the emission of quadrupole waves, and the non-local memory effect due to the re-radiation by the stress-energy distribution of linear waves. Then we compute all the local (instantaneous) terms which are associated in the quadrupole-quadrupole metric with the latter non-local effects. Expanding the metric at large distances from the system, we obtain the corresponding radiation-field observables, including all non-local and transient contributions. This permits notably the completion of the observable quadrupole moment at the 5/2 post-Newtonian order.

The Role of Costal2 and its Collaborators in Regulation of Ci Processing and in Mediation of Response to Hedgehog in Drosophila

Publisher: name: Columbia University

description: Hedgehog (Hh) family proteins specify many cell fates in flies and mammals that depend on Hh concentration. Hh achieves differential expression of target genes by regulating the activity and stability of Cubitus interruptus (Ci) / Glioblastoma (Ci / Gli) transcription factors. Both modes of regulation require kinesin-like protein Costal2 (Cos2) (Kif7 in mammals) that acts in a complex with Fused (Fu) kinase. We used a group of fused (fu) alleles with truncations in the Fu-regulatory domain to confirm the importance of physical association between Cos2 and Fu for processing of Ci-155 to Ci-75 repressor in the absence of Hh. By specifically disrupting Cos2 interaction with Fu using Cos2deltaFu transgenes, we confirmed the importance of this interaction for stability of the Fu protein and for Ci processing when the transgene was expressed at natural levels (under control of genomic regulatory sequences).  It is possible that Cos2/Fu interaction helps recruit processing-promoting kinases to Ci. We found no evidence for the importance of Suppressor of fused (Su(fu)), a protein known to limit Ci activity, in regulating Ci processing. Using a group of Cos2 variants under the control of genomic sequences, we found that expression of the wild type genomic Cos2 transgene (gCos2) or gCos2 deficient in Fu-dependent phosphorylation of Ser572 and Ser931 rescued animals to adulthood. Contrary to past observations of over-expressed phosphorylation variants, these gCos2 transgenes supported normal responses to Hh at the anterior-poster (AP) border of wing discs, a region of active Hh signaling. As shown previously, Ser572 had a role in stabilization of Ci-155 by activated Fu kinase. gCos2deltaFu greatly reduced the response to Hh and was also unable to rescue animal viability. The transgene allowed for induction of ptc-lacZ in response to activated Fu (GAP-Fu) but did not respond to activated Smo (SmoD123), suggesting that it fails to mediate Fu activation in response to activated Smo . Normal accumulation of Smo in the regions of active Hh signaling in cos2-null wing discs expressing Cos2deltaFu also suggested that Cos2deltaFu does not affect the accumulation component of Smo activation. We propose that Cos2deltaFu is defective in promoting Fu activation through cross-phosphorylation of Fu molecules that requires physical interaction with Cos2. Similarly, a gCos2-S182N variant with impaired binding to Ci failed to rescue animal viability and was defective in Ci processing, but gCos2-S182N supported almost normal responses to Hh at the AP border. Ectopic induction of ptc-lacZ in anterior cos2 clones with gCos2-S182N indicated a defect in limiting Ci activity possibly through physical interaction.

A unified treatment of cubic invariants at fixed and arbitrary energy

description: Cubic invariants for two-dimensional Hamiltonian systems are investigated using the Jacobi geometrization procedure. This approach allows for a unified treatment of invariants at both fixed and arbitrary energy. In the geometric picture the invariant generally corresponds to a third rank Killing tensor, whose existence at a fixed energy value forces the metric to satisfy a nonlinear integrability condition expressed in terms of a Kahler potential. Further conditions, leading to a system of equations which is overdetermined except for singular cases, are added when the energy is arbitrary. As solutions to these equations we obtain several new superintegrable cases in addition to the previously known cases. We also discover a superintegrable case where the cubic invariant is of a new type which can be represented by an energy dependent linear invariant. A complete list of all known systems which admit a cubic invariant at arbitrary energy is given.

description: The contributions to the heat kernel coefficients generated by the corners of the boundary are studied. For this purpose the internal and external sectors of a wedge and a cone are considered. These sectors are obtained by introducing, inside the wedge, a cylindrical boundary. Transition to a cone is accomplished by identification of the wedge sides. The basic result of the paper is the calculation of the individual contributions to the heat kernel coefficients generated by the boundary singularities. In the course of this analysis certain patterns, that are followed by these contributions, are revealed. The implications of the obtained results in calculations of the vacuum energy for regions with nonsmooth boundary are discussed. The rules for obtaining all the heat kernel coefficients for the minus Laplace operator defined on a polygon or in its cylindrical generalization are formulated.

description: The sensitive infrared telescopes, Spitzer and Herschel, have been used to target low-metallicity star-forming galaxies, allowing us to investigate the properties of their interstellar medium (ISM) in unprecedented detail. Interpretation of the observations in physical terms relies on careful modeling of those properties. We have employed a multiphase approach to model the ISM phases (HII region and photodissociation region) with the spectral synthesis code Cloudy. Our goal is to characterize the physical conditions (gas densities, radiation fields, etc.) in the ISM of the galaxies from the Herschel Dwarf Galaxy Survey. We are particularly interested in correlations between those physical conditions and metallicity or star-formation rate. Other key issues we have addressed are the contribution of different ISM phases to the total line emission, especially of the [CII]157um line, and the characterization of the porosity of the ISM. We find that the lower-metallicity galaxies of our sample tend to have higher ionization parameters and galaxies with higher specific star-formation rates have higher gas densities. The [CII] emission arises mainly from PDRs and the contribution from the ionized gas phases is small, typically less than 30% of the observed emission. We also find correlation - though with scatter - between metallicity and both the PDR covering factor and the fraction of [CII] from the ionized gas. Overall, the low metal abundances appear to be driving most of the changes in the ISM structure and conditions of these galaxies, and not the high specific star-formation rates. These results demonstrate in a quantitative way the increase of ISM porosity at low metallicity. Such porosity may be typical of galaxies in the young Universe.

description: To investigate the role of experience in interspecific emotion perception, humans with various levels of dog experience provided their interpretations of emotion in dogs using the dogs' visual signals (body language). First, a set of 30 short videos of dogs was assembled, and a panel of eight behavioral experts provided ratings and categorizations of the depicted dogs' emotions. Based on the emotional valence and level of agreement in their ratings, a subset of 16 videos was selected for inclusion in a web survey made available to the general public. The wide range of dog experience found within the final sample of 2,163 participants allowed for various means of assessing the effect of experience on interspecific emotion perception. Responses were analyzed according to broad experience categories (never owned a dog, dog owner, dog professional for less than ten years, dog professional for ten or more years), as well as experience-related variables among the dog owners. Effects on emotion perception were found using all experience-related measures. The level of experience with dogs predicted both ratings and categorizations of emotion in dogs. The role of experience was more evident for emotional displays that had been judged by experts to be clearly negative than clearly positive. Less-experienced individuals tended to provide more positive emotion ratings of negatively-valenced behavior than more-experienced individuals. In addition, they were more likely to diverge from expert evaluations and categorize such behavior as happy, rather than fearful. Furthermore, as previous education about dog body language increased among more-experienced individuals, perceptions became more aligned with expert evaluations, while perceptions of individuals who had never owned a dog became less aligned. Lastly, differences among the experience groups in emotion ratings and categorizations were reflected in differences in observational focus. Individuals with greater experience were more likely to attend to the ears of the dog and less likely to attend to the legs and tail. In sum, individual differences in dog experience were associated with the perception of emotion in dogs, suggesting experience-dependent development of these abilities. These findings are among the first to provide evidence for experience-associated variation in interspecific emotion perception and may illustrate a novel strategy for exploring the development of individual differences in emotion perception in humans.

description: Let k be a p-adic field. Some time ago, D. Harbater [9] proved that any finite group G may be realized as a regular Galois group over the rational function field in one variable k(t), namely there exists a finite field extension $F/k(t)$, Galois with group G, such that F is a regular extension of k (i.e. k is algebraically closed in F). Moreover, one may arrange that a given k-place of k(t) be totally split in F. Harbater proved this theorem for k an arbitrary complete valued field. Rather formal arguments ([10, §4.5]; \S2 hereafter) then imply that the theorem holds over any `large' field k. This in turn is a special case of a result of Pop [15], hence will be referred to as the Harbater/Pop theorem. We refer to [10], [16], [6] for precise references to the literature (work of Dèbes, Deschamps, Fried, Haran, Harbater, Jarden, Liu, Pop, Serre, and Völklein). Most proofs (see [10], [19, 8.4.4, p.~93] and Liu's contribution to [16]; see however [15]) first use direct arguments to establish the theorem when G is a cyclic group (here the nature of the ground field is irrelevant), then proceed by patching, using either formal or rigid geometry, together with GAGA theorems. In the present paper, where I take the case of algebraically closed fields for granted, I show how a technique recently developed by Kollár [12] may be used to give a quite different proof of the Harbater/Pop theorem, when the `large' field k has characteristic zero. This proof actually gives more than the original result (see comment after statement of Theorem 1).

description: We experimentally study a nonlinear optical approach to selective manipulation and detection of structured images mixed with turbulent noise. Unlike any existing adaptive-optics method by applying compensating modulation directly on the images, here we account for the turbulence indirectly, by modulating only the pump driving the nonlinear process but not the images themselves. This indirect approach eliminates any signal modulation loss or noise, while allowing more flexible and capable operations. Using specifically sum frequency generation in a lithium niobate crystal, we demonstrate selective upconversion of Laguerre-Gaussian spatial modes mixed with turbulent noise. The extinction reaches $\sim$40 dB without turbulence, and maintains $\sim$20 dB in the presence of strong turbulence. This technique could find utilities in classical and quantum communications, compressive imaging, pattern recognition, and so on.

description: Certain planetary nebulae contain shells, filaments, or globules of cold gas and dust whose heating and chemistry are likely driven by UV and X-ray emission from their central stars and from wind-collision-generated shocks. We present the results of a survey of molecular line emission in the 88-236 GHz range from nine nearby (<1.5 kpc) planetary nebulae spanning a range of UV and X-ray luminosities, using the 30 m telescope of the Institut de Radioastronomie Millimetrique. Rotational transitions of thirteen molecules, including CO isotopologues and chemically important trace species, were observed and the results compared with and augmented by previous studies of molecular gas in PNe. Lines of the molecules HCO+, HNC, HCN, and CN, which were detected in most objects, represent new detections for five planetary nebulae in our study. Specifically, we present the first detections of 13CO (1-0, 2-1), HCO+, CN, HCN, and HNC in NGC 6445; HCO+ in BD+303639; 13CO (2-1), CN, HCN, and HNC in NGC 6853; and 13CO (2-1) and CN in NGC 6772. Flux ratios were analyzed to identify correlations between the central star and/or nebular UV and X-ray luminosities and the molecular chemistries of the nebulae. This analysis reveals a surprisingly robust dependence of the HNC/HCN line ratio on PN central star UV luminosity. There exists no such clear correlation between PN X-rays and various diagnostics of PN molecular chemistry. The correlation between HNC/HCN ratio and central star UV luminosity demonstrates the potential of molecular emission line studies of PNe for improving our understanding of the role that high-energy radiation plays in the heating and chemistry of photodissociation regions.

description: Whereas magnetic frustration is typically associated with local-moment magnets in special geometric arrangements, here we show that SrCo$_{2}$As$_{2}$ is a candidate for frustrated itinerant magnetism. Using inelastic neutron scattering (INS), we find that antiferromagnetic (AF) spin fluctuations develop in the square Co layers of SrCo$_{2}$As$_{2}$ below $T\approx100$ K centered at the stripe-type AF propagation vector of $(\frac{1}{2},~\frac{1}{2})$, and that their development is concomitant with a suppression of the uniform magnetic susceptibility determined via magnetization measurements. We interpret this switch in spectral weight as signaling a temperature-induced crossover from an instability towards FM ordering to an instability towards stripe-type AF ordering on cooling, and show results from Monte-Carlo simulations for a $J_{1}$-$J_{2}$ Heisenberg model that illustrate how the crossover develops as a function of the frustration ratio $-J_1/(2J_2)$. By putting our INS data on an absolute scale, we quantitatively compare them and our magnetization data to exact-diagonalization calculations for the $J_{1}$-$J_{2}$ model [N. Shannon et al., Eur. Phys. J. B 38, 599 (2004)], and show that the calculations predict a lower level of magnetic frustration than indicated by experiment. We trace this discrepancy to the large energy scale of the fluctuations ($J_{\text{avg}}\gtrsim75$ meV), which, in addition to the steep dispersion, is more characteristic of itinerant magnetism.

description: A functional integral technique is used to study the ultraviolet or short distance properties of the Kardar-Parisi-Zhang (KPZ) equation with white Gaussian noise. We apply this technique to calculate the one-loop effective potential for the KPZ equation. The effective potential is (at least) one-loop ultraviolet renormalizable in 1, 2, and 3 space dimensions, but non-renormalizable in 4 or higher space dimensions. This potential is intimately related to the probability distribution function (PDF) for the spacetime averaged field. For the restricted class of field configurations considered here, the KPZ equation exhibits dynamical symmetry breaking (DSB) via an analog of the Coleman-Weinberg mechanism in 1 and 2 space dimensions, but not in 3 space dimensions.

description: Deep learning techniques have enabled the emergence of state-of-the-art models to address object detection tasks. However, these techniques are data-driven, delegating the accuracy to the training dataset which must resemble the images in the target task. The acquisition of a dataset involves annotating images, an arduous and expensive process, generally requiring time and manual effort. Thus, a challenging scenario arises when the target domain of application has no annotated dataset available, making tasks in such situation to lean on a training dataset of a different domain. Sharing this issue, object detection is a vital task for autonomous vehicles where the large amount of driving scenarios yields several domains of application requiring annotated data for the training process. In this work, a method for training a car detection system with annotated data from a source domain (day images) without requiring the image annotations of the target domain (night images) is presented. For that, a model based on Generative Adversarial Networks (GANs) is explored to enable the generation of an artificial dataset with its respective annotations. The artificial dataset (fake dataset) is created translating images from day-time domain to night-time domain. The fake dataset, which comprises annotated images of only the target domain (night images), is then used to train the car detector model. Experimental results showed that the proposed method achieved significant and consistent improvements, including the increasing by more than 10% of the detection performance when compared to the training with only the available annotated data (i.e., day images).

description: Obesity has been established as a significant risk factor for osteoarthritis. Anti-obesity medications (AOMs) have demonstrated efficacy in weight management. However, potential impact on osteoarthritis risk remains uncertain. This retrospective cohort study used Kythera data from NOV2022 to JULY2024. Patients with obesity using AOMs were identified through diagnosis and prescription claims for tirzepatide, semaglutide, or liraglutide between 1NOV2023 and 31JAN2024, with a 6-month follow-up to assess OA risk. OA risk, analyzed using Cox regression and propensity score matching, controlled for comorbidities and sociodemographic factors. There were 39,394 patients living with obesity using AOM (23,933 semaglutide 12,854 tirzepatide, 2,607 liraglutide) and 72,405 without AOM use. The adjusted osteoarthritis risk was 27% % lower in AOM users than in non-users (hazard ratio (HR) = 073, 95% CI (0.67–0.79), p < 0.01). Among AOMs, tirzepatide was associated with a significantly lower osteoarthritis (OA) risk compared to semaglutide (HR = 0.57, 95% CI: 0.50–0.65, p < 0.0001). Liraglutide was linked to a significantly higher OA risk vs tirzepatide (HR = 1.63, 95% CI: 1.23–2.15, p = 0.0007). AOM use was associated with a significantly lower risk of OA and may be an effective obesity management intervention.

Gravitational-wave tails of tails

description: The tails of gravitational waves are caused by scattering of linear waves onto the space-time curvature generated by the total mass-energy of the source. Quite naturally, the tails of tails are caused by curvature scattering of the tails of waves themselves. The tails of tails are associated with the cubic non-linear interaction between two mass monopole moments and, dominantly, the mass quadrupole of the source. In this paper we determine the radiation field at large distances from the source for this particular monopole-monopole-quadrupole interaction. We find that the tails of tails appear at the third post-Newtonian (3PN) order beyond the usual quadrupole radiation. Motivated by the need of accurate templates to be used in the data analysis of future detectors of gravitational waves, we compute the contribution of tails, and of tails of tails, up to the 3.5PN order in the energy flux generated by inspiraling compact binaries.

The Role of Hippocampus in Signal Processing and Memory

description: Historically, there have been two lines of research on mammalian hippocampus. The first one is concerned with the role of hippocampus in formations of new memories and owes its origin to the seminal study by Brenda Milner and William Scoville of a single memory disorder patient, widely known as H.M. The second line of research views the hippocampus as the brain area concerned with orienting and navigating in space. It started with John O’Keefe’s discovery of place cells, pyramidal neurons in the CA3 area of hippocampus, that fire when the animal enters a particular place in its environment.
      I argue that both lines of discoveries seem to be consistent with a more general view of hippocampus as a brain area strongly involved in the integration of sensory, and possibly internal, information.
      The first part of the thesis presents an investigation of the effect of limited connectivity constraint on the model network in the framework of pattern classification. It is shown that feed-forward neural classifiers with numerous long range connections can be replaced by networks with sparse feed-forward connectivity and local recurrent connectivity without sacrificing the classification performance. The limited connectivity constraint is relevant for most biological networks, and especially for the hippocampus.
      The second part describes a decoding analysis from the calcium signal recorded in mouse dentate gyrus. The animal’s position can be decoded with approximately 10cm accuracy and the neural representation of position in the dentate gyrus have close to maximal dimensionality. The analysis also suggests that cells with single firing field and cells with multiple firing fields contribute approximately equal amount of information to the decoder.
Mars Obliquity History Constrained by Elliptic Crater Orientations

description: The dynamics of Mars' obliquity are believed to be chaotic, and the historical ~3.5 Gyr (late-Hesperian onward) obliquity probability density function (PDF) is high uncertain and cannot be inferred from direct simulation alone. Obliquity is also a strong control on post-Noachian Martian climate, enhancing the potential for equatorial ice/snow melting and runoff at high obliquities (> 40°) and enhancing the potential for desiccation of deep aquifers at low obliquities (< 25°). We developed a new technique using the orientations of elliptical craters to constrain the true late-Hesperian-onward obliquity PDF. To do so, we developed a forward model of the effect of obliquity on elliptic crater orientations using ensembles of simulated Mars impactors and ~3.5 Gyr-long Mars obliquity simulations. In our model, the inclinations and speeds of Mars crossing objects bias the preferred orientation of elliptic craters which are formed by low-angle impacts. Comparison of our simulation predictions with a validated database of elliptic crater orientations allowed us to invert for best-fitting obliquity history. We found that since the onset of the late-Hesperian, Mars' mean obliquity was likely low, between ~10° and ~30°, and the fraction of time spent at high obliquities > 40° was likely < 20%.

description: Let $\{b(n):n\in\N\}$ be the sequence of coefficients in the Taylor expansion of a rational function $R(X)\in\Q(X)$ and suppose that b(n) is a perfect $d^{\rm th}$ power for all large n. A conjecture of Pisot states that one can choose a $d^{\rm th}$ root a(n) of b(n) such that $\sum a(n)X^n$ is also a rational function. Actually, this is the fundamental case of an analogous statement formulated for fields more general than $\Q$. A number of papers have been devoted to various special cases. In this note we shall completely settle the general case.

description: Maternal mortality is a prevalent problem around the world, but it disproportionately affects developing countries, especially those in sub-Saharan Africa. Over the last four decades, there have been substantial shifts in the discourse surrounding maternal mortality. The issue has gone from being considered a matter of development to being increasingly recognized as a human rights priority. There have also been changes in development discourse more broadly, as human rights-based approaches (HRBAs) have gained support. This thesis examines whether the shifts in discourse are reflected in the maternal health practices of four development NGOs: CARE International, Pathfinder International, Women and Children First and Jhpiego. It considers the organizations’ maternal mortality programs in sub-Saharan Africa and finds that they present some inconsistencies with a human rights perspective of maternal mortality and with HRBAs. It argues that these inconsistencies undermine women’s human rights and that development NGOs working on maternal mortality should be more consistent in their commitment to human rights by reflecting it in their practice.

description: A new family of self-consistent DF-based models of stellar systems is explored. The stellar component of the models is described by a distribution function (DF) depending on the action integrals, previously used to model the Fornax dwarf spheroidal galaxy (dSph). The stellar component may cohabit with either a dark halo, also described by a DF, or with a massive central black hole. In all cases we solve for the model's self-consistent potential. Focussing on spherically symmetric models, we show how the stellar observables vary with the anisotropy prescribed by the DF, with the dominance and nature of the dark halo, and with the mass of the black hole. We show that precise fits to the observed surface brightness profiles of four globular clusters can be obtained for a wide range of prescribed velocity anisotropies. We also obtain precise fits to the observed projected densities of four dSphs. Finally, we present a three-component model of the Scupltor dSph with distinct DFs for the red and blue horizontal branch stars and the dark matter halo.

Scaling and percolation in the small-world network model

description: In this paper we study the small-world network model of Watts and Strogatz, which mimics some aspects of the structure of networks of social interactions. We argue that there is one non-trivial length-scale in the model, analogous to the correlation length in other systems, which is well-defined in the limit of infinite system size and which diverges continuously as the randomness in the network tends to zero, giving a normal critical point in this limit. This length-scale governs the cross-over from large- to small-world behavior in the model, as well as the number of vertices in a neighborhood of given radius on the network. We derive the value of the single critical exponent controlling behavior in the critical region and the finite size scaling form for the average vertex-vertex distance on the network, and, using series expansion and Pade approximants, find an approximate analytic form for the scaling function. We calculate the effective dimension of small-world graphs and show that this dimension varies as a function of the length-scale on which it is measured, in a manner reminiscent of multifractals. We also study the problem of site percolation on small-world networks as a simple model of disease propagation, and derive an approximate expression for the percolation probability at which a giant component of connected vertices first forms (in epidemiological terms, the point at which an epidemic occurs). The typical cluster radius satisfies the expected finite size scaling form with a cluster size exponent close to that for a random graph. All our analytic results are confirmed by extensive numerical simulations of the model.
