A search for mass segregation of stars and brown dwarfs in ρ Ophiuchi

description: We apply two different algorithms to search for mass segregation to a recent observational census of the rho Ophiuchi star forming region. Firstly, we apply the Lambda_MSR method, which compares the minimum spanning tree (MST) of a chosen subset of stars to MSTs of random subsets of stars in the cluster, and determine the mass segregation ratio, Lambda_MSR. Secondly, we apply the m-Sigma method, which calculates the local stellar surface density around each star and determines the statistical significance of the average surface density for a chosen mass bin, compared to the average surface density in the whole cluster. Using both methods, we find no indication of mass segregation (normal or inverse) in the spatial distribution of stars and brown dwarfs in rho Ophiuchi. Although rho Ophiuchi suffers from high visual extinction, we show that a significant mass segregation signature would be detectable, albeit slightly diluted, despite dust obscuration of centrally located massive stars.

description: We report the discovery of X-ray emission at the position of the old classical nova DK Lacertae using the Swift satellite. Three observations were conducted using the X-ray telescope 62 years after the discovery of the nova, yielding 46 source signals in an exposure time of 4.8 ks. A background-subtracted count rate was 9+/-2x10^{-3} counts s^{-1}, corresponding to a detection significance level of 5-sigma. The X-ray spectrum was characterized by a continuum extending up to about 7 keV, which can be modeled by a power-law component with a photon index of 1.4--5.6, or by a thermal bremsstrahlung component with a temperature of 0.7--13.3 keV, convolved with interstellar absorption with an equivalent hydrogen column density of 0.3--2.4x10^{22} cm^{-2}. Assuming a distance of 3900 pc to the source, the luminosity was 10^{32}--10^{34} ergs s^{-1} in the 0.3--10 keV energy band. The origin of X-rays is considered to be either mass accretion on the white dwarf or adiabatic shocks in nova ejecta, with the former appearing much more likely. In either case, DK Lacertae represents a rare addition to the exclusive club of X-ray emitting old novae.

description: A detection or non detection of primordial non--Gaussianity (NG) by using the cosmic microwave background radiation (CMB) is a possible way to break the degeneracy of early universe models. Since a single statistical estimator hardly can be sensitive to all possible forms of NG which may be present in the data, it is important to use different statistical estimators to study NG in CMB. Recently, two new large-angle NG indicators based on skewness and kurtosis of spherical caps or spherical cells of CMB sky have been proposed and used in both CMB data and simulated maps. Here, we make a comparative study of these two different procedures by examining the NG in the WMAP seven years ILC map. We show that the spherical cells procedure detects a higher level of NG than that obtained by the method with overlapping spherical caps.

description: This paper is to introduce a new software called CBwaves which provides a fast and accurate computational tool to determine the gravitational waveforms yielded by generic spinning binaries of neutron stars and/or black holes on eccentric orbits. This is done within the post-Newtonian (PN) framework by integrating the equations of motion and the spin precession equations while the radiation field is determined by a simultaneous evaluation of the analytic waveforms. In applying CBwaves various physically interesting scenarios have been investigated. In particular, we have studied the appropriateness of the adiabatic approximation, and justified that the energy balance relation is indeed insensitive to the specific form of the applied radiation reaction term. By studying eccentric binary systems it is demonstrated that circular template banks are very ineffective in identifying binaries even if they possess tiny residual orbital eccentricity. In addition, by investigating the validity of the energy balance relation we show that, on contrary to the general expectations, the post-Newtonian approximation should not be applied once the post-Newtonian parameter gets beyond the critical value $\sim 0.08-0.1$. Finally, by studying the early phase of the gravitational waves emitted by strongly eccentric binary systems---which could be formed e.g. in various many-body interactions in the galactic halo---we have found that they possess very specific characteristics which may be used to identify these type of binary systems.

title: Understanding Natural Geomorphological Processes Through Artificial Intelligence and Crowdsourced Data
Creators: name:  Chen ,  Thomas Y.
Publisher: name: Deutsche Geologische Gesellschaft - Geologische Vereinigung e.V. (DGGV)
Year: 2021

description: As open source data becomes more ubiquitous, the involvement of citizen scientists has increased. The collection of large quantities of relevant data and respective labels through crowdsourcing on online platforms has yielded many exciting opportunities for machine learning applications. In geomorphology, multitemporal imagery, much of which is captured through crowdsourcing, is especially useful for training deep learning models for change detection in landscapes. This is relevant in terms of natural hazards that occur, including endogenous types like volcanoes and neotectonics, exogenous ones such as floods, karst collapses, sedimentation, erosion, tsunamis, and avalanches, as well as climate change or land use-induced hazards like permafrost and desertification. However, a challenge when harnessing crowdsourced imagery is the disorganized and “unclean” fashion in which it often presents itself. Cleaning data prior to training neural network-based computer vision models is key to success in any geomorphology change detection research. We discuss approaches such as manual techniques, image restoration and denoising, and image duplication reduction. The goal is to assimilate a diverse range of data collected from many sources to successfully train machine learning algorithms. In a broader sense, this research has the potential to save lives by detecting possibly destructive and dangerous geomorphological change, and to conserve environments that have been affected severely.
The effect of poloidal velocity shear on the local development of current-driven instabilities

description: We perform a local (short-wavelength) linear stability analysis of an axisymmetric column of magnetized plasma with a nearly toroidal magnetic field and a smooth poloidal velocity shear by perturbing the equations of relativistic magnetohydrodynamics. We identify two types of unstable modes, which we call 'exponential' and 'overstable', respectively. The exponential modes are present in the static equilibria and their growth rates decrease with increasing velocity shear. The overstable modes are driven by the effects of velocity shear and dominate the exponential modes for sufficiently high shear values. We argue that these local instabilities can provide an important energy dissipation mechanism in astrophysical relativistic jets. Strong co-moving velocity shear arises naturally in the magnetic acceleration mechanism, therefore it may play a crucial role in converting Poynting-flux-dominated jets into matter-dominated jets, regulating the global acceleration and collimation processes, and producing the observed emission of blazars and gamma-ray bursts.

description: The study explores the public perceptions of women in politics, focusing on the perspectives of Ghanaian youth. It reveals that societal norms and gender stereotypes contribute to the marginalisation of women in political positions. Participants' perceptions ranged from viewing women in politics as arrogant to acknowledging the impact of stereotypical generalisations. The study emphasises the competing expectations faced by women aspiring to be leaders and the influence of public perceptions on their opportunities and challenges. Positive perceptions include perceiving women as less corrupt and more accountable, while negative stereotypes label them radical feminists or inadequate leaders. The findings contribute to the existing literature on gender and politics, providing insights for social workers and policymakers to advocate for equal opportunities and increase women's political participation.

description: Recently, gauge field theory approaches were extensively used in order to discuss the physical consequences of spin-orbit interactions in condensed matter physics. An SU(2)$\times$U(1) gauge theory is very naturally borne out and provides an illustrative example of a classical Yang-Mills field theory at work. This approach may serve as an exemplification of non-Abelian field theories for students in general physics curriculum. It allows to introduce discussions on fundamental ideas like Noether currents, gauge symmetry principle, gauge symmetry breaking and non linear Yang Mills equations in very concrete physical situations that makes it accessible to a broad audience.

description: The possibility for proteins to aggregate in different superstructures, i.e. large-scale polymorphism, has been widely observed, but an understanding of the physico-chemical mechanisms behind it is still out of reach. Here we present a theoretical model for the description of a generic aggregate formed from an ensemble of charged proteins. The model predicts the formation of multi-fractal structures with the geometry of the growth determined by the electrostatic interactions between single proteins. The model predictions are successfully verified in comparison with experimental curves for aggregate growth. The model is general and is able to predict aggregate morphologies occurring both in vivo and in vitro. Our findings provide for the first time a unifying and general framework where the physical interactions between single proteins, the aggregate morphology and the growth kinetics are connected into a single model in excellent agreement with the experimental data.

Study of Scheme Transformations to Remove Higher-Loop Terms in the $β$ Function of a Gauge Theory
Creators: name: Shrock, Robert
Publisher: name: arXiv
Year: 2013
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Since three-loop and higher-loop terms in the $β$ function of a gauge theory are scheme-dependent, one can, at least for sufficiently small coupling, carry out a scheme transformation that removes these terms. A basic question concerns the extent to which this can be done at an infrared fixed point of an asymptotically free gauge theory. This is important for quantitative analyses of the scheme dependence of such a fixed point. Here we study a scheme transformation $S_{R,m}$ with $m \ge 2$ that is constructed so as to remove the terms in the beta function at loop order $\ell=3$ to $\ell=m+1$, inclusive. Starting from an arbitrary initial scheme, we present general expressions for the coefficients of terms of loop order $\ell$ in the beta function in the transformed scheme from $\ell=m+2$ up to $\ell=8$. Extending a previous study of $S_{R,2}$, we investigate the range of applicability of the $S_{R,3}$ scheme transformation in an asymptotically free SU($N_c$) gauge theory with an infrared zero in $β$ depending on the number, $N_f$, of fermions in the theory. We show that this $S_{R,3}$ scheme transformation can only be applied self-consistently in a restricted range of $N_f$ with a correspondingly small value of infrared fixed-point coupling. We also study the effect of higher-loop terms on the beta function of a U(1) gauge theory.

description: We formulate low Mach number fluctuating hydrodynamic equations appropriate for modeling diffusive mixing in isothermal mixtures of fluids with different density and transport coefficients. These equations eliminate the fluctuations in pressure associated with the propagation of sound waves by replacing the equation of state with a local thermodynamic constraint. We demonstrate that the low Mach number model preserves the spatio-temporal spectrum of the slower diffusive fluctuations. We develop a strictly conservative finite-volume spatial discretization of the low Mach number fluctuating equations in both two and three dimensions and construct several explicit Runge-Kutta temporal integrators that strictly maintain the equation of state constraint. The resulting spatio-temporal discretization is second-order accurate deterministically and maintains fluctuation-dissipation balance in the linearized stochastic equations. We apply our algorithms to model the development of giant concentration fluctuations in the presence of concentration gradients, and investigate the validity of common simplifications such as neglecting the spatial non-homogeneity of density and transport properties. We perform simulations of diffusive mixing of two fluids of different densities in two dimensions and compare the results of low Mach number continuum simulations to hard-disk molecular dynamics simulations. Excellent agreement is observed between the particle and continuum simulations of giant fluctuations during time-dependent diffusive mixing.

description: We present observations of 32 primarily bright, newly discovered Transneptunian objects observable from the Southern Hemisphere during 39 nights of observation with the 2.5-m telescope at Las Campanas Observatory. Our dataset includes objects in all dynamical classes, but is weighted towards Scattered objects. We find 15 objects for which we can fit periods and amplitudes to the data, and place lightcurve amplitude upper limits on the other 17 objects. Combining our sample with the larger sample in the literature, we find a 3-sigma correlation between lightcurve amplitude and absolute magnitude with fainter objects having larger lightcurve amplitudes. We looked for correlations between lightcurve and individual orbital properties, but did not find any statistically significant results. However, if we consider lightcurve properties with respect to dynamical classification, we find statistically different distributions between the Classical-Scattered and Classical-Resonant populations, respectively, with the Classical objects having larger amplitude lightcurves. The properties of binary lightcurves are largely consistent with the greater population except in the case of tidally locked systems. All the Haumea family objects measured so far have measurable amplitudes and rotation periods le 10 hr suggesting that they are not significantly different from the larger TNO population. We expect multiple factors are influencing object rotations: object size dominates lightcurve properties except in the case of tidal, or proportionally large collisional interactions with other objects, the influence of the latter being different for each sub-population. We also present phase curves and colors for some objects; our values are not significantly different from those presented in the literature for other samples.

description: General Lagrangian theory of discrete one-dimensional integrable systems is illustrated by a detailed study of Bäcklund transformations for Toda-type systems. Commutativity of Bäcklund transformations is shown to be equivalent to consistency of the system of discrete multi-time Euler-Lagrange equations. The precise meaning of the commutativity in the periodic case, when all maps are double-valued, is established. It is shown that gluing of different branches is governed by the so called superposition formulas. The closure relation for the multi-time Lagrangian 1-form on solutions of the variational equations is proved for all Toda-type systems. Superposition formulas are instrumental for this proof. The closure relation was previously shown to be equivalent to the spectrality property of Bäcklund transformations, i.e., to the fact that the derivative of the Lagrangian with respect to the spectral parameter is a common integral of motion of the family of Bäcklund transformations. We relate this integral of motion to the monodromy matrix of the zero curvature representation which is derived directly from equations of motion in an algorithmic way. This serves as a further evidence in favor of the idea that Bäcklund transformations serve as zero curvature representations for themselves.

description: A method is developed for calculating the jet mass distribution at hadron colliders using an expansion about the kinematic threshold. In particular, we consider the mass distribution of jets of size R produced in association with a hard photon at the Large Hadron Collider. Expanding around the kinematic threshold, where all the energy goes into the jet and the photon, provides a clean factorization formula and allows for the resummation of logarithms associated with soft and collinear divergences. All of the large logarithms of jet mass are resummed at next-to-leading logarithmic level (NLL), and all the global logarithms at next-to-next-to-leading logarithmic level (NNLL). A key step in the derivation is the factorization of the soft function into pieces associated with single scales and a remainder which contains non-global structure. This step, which is standard in traditional resummation, is implemented in effective field theory which is then used to resum the large logarithms using the renormalization group in a systematically improvable manner.

description: We quantify the accuracy with which the cosmological parameters characterizing the energy density of matter (Ω_m), the amplitude of the power spectrum of matter fluctuations (σ_8), the energy density of neutrinos (Ω_ν) and the dark energy equation of state (w_0) can be constrained using data from large galaxy redshift surveys. We advocate a joint analysis of the abundance of galaxies, galaxy clustering, and the galaxy-galaxy weak lensing signal in order to simultaneously constrain the halo occupation statistics (i.e., galaxy bias) and the cosmological parameters of interest. We parameterize the halo occupation distribution of galaxies in terms of the conditional luminosity function and use the analytical framework of the halo model described in our companion paper (van den Bosch et al. 2012), to predict the relevant observables. By performing a Fisher matrix analysis, we show that a joint analysis of these observables, even with the precision with which they are currently measured from the Sloan Digital Sky Survey, can be used to obtain tight constraints on the cosmological parameters, fully marginalized over uncertainties in galaxy bias. We demonstrate that the cosmological constraints from such an analysis are nearly uncorrelated with the halo occupation distribution constraints, thus, minimizing the systematic impact of any imperfections in modeling the halo occupation statistics on the cosmological constraints. In fact, we demonstrate that the constraints from such an analysis are both complementary to and competitive with existing constraints on these parameters from a number of other techniques, such as cluster abundances, cosmic shear and/or baryon acoustic oscillations, thus paving the way to test the concordance cosmological model.

description: IMPETUS is a Horizon Europe project which aims to enable and support citizen science initiatives. As part of that process, IMPETUS provides funding for citizen science initiatives through an open call. This deliverable (D4.1) outlines draft guidelines for how to localise the Sustainable Development Goal (SDG) targets to neighbourhood, city and regional levels and the specific role citizen science can play in this. These guidelines aim to simplify the process of localising SDGs for local-level administrations across Europe. They also demonstrate the central role of citizen science in achieving the ambitious vision outlined in the SDGs and the European Green Deal. Throughout the guidelines we provide examples of best practice to support the integration of citizen science outputs into policy development, and to raise awareness about the potential of citizen science data to monitor progress towards local, national and global sustainability targets. These guidelines will be revised and edited throughout the course of the IMPETUS project (2022-2026) as they are tested and refined through planned activities with decision makers. This document is therefore not the final version of the guidelines, but a draft version.

Enabling and investigating real-time monoclonal antibody N-linked glycosylation for upstream processing of biotherapeutics

Year: 2023

description: Monoclonal antibodies (mAbs) make up the largest class of biologics on the market today based on their use to treat a myriad of diseases such as cancers, and autoimmune diseases. The past decade saw advancements in the production of these biologics with the creation of cell lines that can produce high product titers and better-quality profiles. However, the current bottlenecks are within the throughput in production and the lack of integrative tools that will allow for homogenous production through process monitoring and control strategies. This is due to the inherent complexity of the biological cell metabolism. With new regulatory advisement from the U.S. FDA, the biopharmaceutical industry is looking to produce process analytical technology (PAT) that will allow for a better understanding of the bioprocess, which will also lead toward a more streamlined operational mode, known as continuous bioprocessing. One critical product parameter is N-Glycosylation: a post-translation modification in which oligosaccharides (i.e., glycans) are attached to the mAb. Glycans are an important modification as they influence the efficacy and safety of the biologic, however, the glycosylation pathway is heterogenous and sensitive to perturbations during bioprocessing which can lead to inadequate glycan profiles. Current technology does not allow for frequent measurements of the parameter as sample preparation and analysis is labor intensive and not automated. The early chapters of this thesis look to introduce and explain the current landscape in continuous bioprocessing (PAT, process monitor and control) and how glycan sample preparations can be used to facilitate this operational mode [chapter 1-3]. It then looks to explain the creation of a PAT tool, called the N-GLYcanyzer, which looks to disrupt current technology for glycosylation measurement by allowing for real-time glycan analysis [chapter 4]. Advances in the N-GLYcanyzer chemistry is then explained in which streamlined kit chemistries are integrated, allowing for higher throughput monitoring with a near order of magnitude gain in sample prep and analysis speed [chapter 5]. Finally, the utility of N-GLYcanyzer is showcased for glycan monitoring with the use of glycan precursor feeding to measure temporal changes in glycosylation during traditional fed-batch mode and continuous perfusion processing [chapter 6]. Overall, this work looks to explain the development and implementation of a PAT toolkit that will allow for real-time high throughput glycosylation analysis and will enable glycosylation control during bioprocessing leading to more heterogenous biotherapeutics, and allow for real-time product release.

description: Spin ice illustrates many unusual magnetic properties, including zero point entropy, emergent monopoles and a quasi liquid-gas transition. To reveal the quantum spin dynamics that underpin these phenomena is an experimental challenge. Here we show how crucial information is contained in the frequency dependence of the magnetic susceptibility and in its high frequency or adiabatic limit. These measures indicate that monopole diffusion is strictly Brownian but is underpinned by spin tunnelling and is influenced by collective monopole interactions. We also find evidence of driven monopole plasma oscillations in weak applied field, and unconventional critical behaviour in strong applied field. Our results resolve contradictions in the present understanding of spin ice, reveal unexpected physics and establish adiabatic susceptibility as a revealing characteristic of exotic spin systems.

description: We derive a new set of field equations within the framework of the Palatini formalism.These equations are a natural generalization of the Einstein-Maxwell equations which arise by adding a function $\mathcal{F}(\mathcal{Q})$, with $\mathcal{Q}\equiv F^{αβ}F_{αβ}$ to the Palatini Lagrangian $f(R,Q)$.The result we obtain can be viewed as the coupling of gravity with a nonlinear extension of the electromagnetic field.In addition,a new method is introduced to solve the algebraic equation associated to the Ricci tensor.

description: We study integrating (that is expanding to a Hasse-Schmidt derivation) derivations, and more generally truncated Hasse-Schmidt derivations, satisfying iterativity conditions given by formal group laws. Our results concern the cases of the additive and the multiplicative group laws. We generalize a theorem of Matsumura about integrating nilpotent derivations (such a generalization is implicit in work of Ziegler) and we also generalize a theorem of Tyc about integrating idempotent derivations.

description: In life sciences, the determination of macromolecular structures and their functions, particularly proteins and protein complexes, is of paramount importance, as these molecules play critical roles within cells. The specific physical interactions of macromolecules govern molecular and cellular functions, making the 3D structure elucidation of these entities essential for comprehending the mechanisms underlying life processes, diseases, and drug discovery. Cryo-electron microscopy (cryo-EM) has emerged as a promising experimental technique for obtaining 3D macromolecular structures. In the course of my research, I proposed CryoREAD, an innovative AI-based method for de novo DNA/RNA structure modeling. This novel approach represents the first fully automated solution for DNA/RNA structure modeling from cryo-EM maps at near-atomic resolution. However, as the resolution decreases, structure modeling becomes significantly more challenging. To address this challenge, I introduced Emap2sec+, a 3D deep convolutional neural network designed to identify protein secondary structures, RNA, and DNA information from cryo-EM maps at intermediate resolutions ranging from 5-10 Å. Additionally, I presented Alpha-EM-Multimer, a groundbreaking method for automatically building full protein complexes from cryo-EM maps at intermediate resolution. Alpha-EM-Multimer employs a diffusion model to trace the protein backbone and subsequently fits the AlphaFold predicted single-chain structure to construct the complete protein complex. Notably, this method stands as the first to enable the modeling of protein complexes with more than 10,000 residues for cryo-EM maps at intermediate resolution, achieving an average TM-Score of predicted protein complexes above 0.8, which closely approximates the native structure. Furthermore, I addressed the recognition of local structural errors in predicted and experimental protein structures by proposing DAQ, an evaluation approach for experimental protein structure quality that utilizes detection probabilities derived from cryo-EM maps via a pretrained multi-task neural network. In the pursuit of evaluating protein complexes generated through computational methods, I developed GNN-DOVE and DOVE, leveraging convolutional neural networks and graph neural networks to assess the accuracy of predicted protein complex structures. These advancements in cryo-EM-based structural modeling and evaluation methodologies hold significant promise for advancing our understanding of complex macromolecular systems and their biological implications.
