description: Recent experiments have reported lower critical solution temperature (LCST) phase behavior of aqueous solutions of proteins induced by multivalent ions, where the solution phase separates upon heating. This phenomenon is linked to complex hydration effects that result in a net entropy gain upon phase separation. To decipher the underlying molecular mechanism, we use all-atom molecular dynamics simulations along with the two-phase thermodynamic method for entropy calculation. Based on simulations of a single BSA protein in various salt solutions (NaCl, CaCl_2, MgCl_2, and YCl_3) at temperatures (T) ranging 283-323 K, we find that the cation-protein binding affinity increases with T, reflecting its thermodynamic driving force to be entropic in origin. We show that in the cation binding process, many tightly bound water molecules from the solvation shells of a cation and the protein are released to the bulk, resulting in entropy gain. To rationalize the LCST behavior, we calculate the ζ-potential that shows charge inversion of the protein for solutions containing multivalent ions. The ζ-potential increases with T. Performing simulations of two BSA proteins, we demonstrate that the protein-protein binding is mediated by multiple cation bridges and involves similar dehydration effects that cause a large entropy gain which more than compensates for rotational and translational entropy losses of the proteins. Thus, the LCST behavior is entropy-driven, but the associated solvation effects are markedly different from hydrophobic hydration. Our findings have direct implications for tuning the phase behavior of biological and soft-matter systems, e.g., protein condensation and crystallization.

description: A new multimodal biometric database designed and acquired within the framework of the European BioSecure Network of Excellence is presented. It is comprised of more than 600 individuals acquired simultaneously in three scenarios: 1) over the Internet, 2) in an office environment with desktop PC, and 3) in indoor/outdoor environments with mobile portable hardware. The three scenarios include a common part of audio/video data. Also, signature and fingerprint data have been acquired both with desktop PC and mobile portable hardware. Additionally, hand and iris data were acquired in the second scenario using desktop PC. Acquisition has been conducted by 11 European institutions. Additional features of the BioSecure Multimodal Database (BMDB) are: two acquisition sessions, several sensors in certain modalities, balanced gender and age distributions, multimodal realistic scenarios with simple and quick tasks per modality, cross-European diversity, availability of demographic data, and compatibility with other multimodal databases. The novel acquisition conditions of the BMDB allow us to perform new challenging research and evaluation of either monomodal or multimodal biometric systems, as in the recent BioSecure Multimodal Evaluation campaign. A description of this campaign including baseline results of individual modalities from the new database is also given. The database is expected to be available for research purposes through the BioSecure Association during 2008

description: Automatically verifying the identity of a person by means of biometrics is an important application in day-to-day activities such as accessing banking services and security control in airports. To increase the system reliability, several biometric devices are often used. Such a combined system is known as a multimodal biometric system. This paper reports a benchmarking study carried out within the framework of the BioSecure DS2 (Access Control) evaluation campaign organized by the University of Surrey, involving face, fingerprint, and iris biometrics for person authentication, targeting the application of physical access control in a medium-size establishment with some 500 persons. While multimodal biometrics is a well-investigated subject, there exists no benchmark for a fusion algorithm comparison. Working towards this goal, we designed two sets of experiments: quality-dependent and cost-sensitive evaluation. The quality-dependent evaluation aims at assessing how well fusion algorithms can perform under changing quality of raw images principally due to change of devices. The cost-sensitive evaluation, on the other hand, investigates how well a fusion algorithm can perform given restricted computation and in the presence of software and hardware failures, resulting in errors such as failure-to-acquire and failure-to-match. Since multiple capturing devices are available, a fusion algorithm should be able to handle this nonideal but nevertheless realistic scenario. In both evaluations, each fusion algorithm is provided with scores from each biometric comparison subsystem as well as the quality measures of both template and query data. The response to the call of the campaign proved very encouraging, with the submission of 22 fusion systems. To the best of our knowledge, this is the first attempt to benchmark quality-based multimodal fusion algorithms.

The CubeSpec space mission: high-resolution optical time-series spectroscopy for asteroseismology of massive stars
Creators: name: Bowman, Dominic
Publisher: name: Zenodo
Year: 2024

description: There is currently a niche for providing high-cadence, high-resolution, time-series optical spectroscopy from space, which can be filled by using a low-cost cubesat mission. The ESA/KU Leuven CubeSpec mission, approved as an ESA in-orbit demonstrator to be launched in 2026, is specifically designed to provide low-cost space-based spectroscopy. CubeSpec's technical capabilities allow for high-cadence monitoring of bright massive stars, and primarily will unlock their interiors using asteroseismology. Here we provide an overview of the CubeSpec design, its science requirements and expected performance for the wider community. Time-series analysis of spectral line profile variability, in particular the silicon triplet, reveals the geometry of pulsation modes in terms of spherical harmonics, which is a critical input for asteroseismic modelling. Furthermore, high-cadence spectroscopy of massive stars represents a novel and unique data set for studying winds, the physical origin of macroturbulence, as well as the consequences of rapid rotation and binarity. Among the 90 massive stars that meet CubeSpec's brightness requirements, we identify 23 beta Cephei pulsators with high-amplitude (non-)radial pulsation modes using light curves from the high-precision and all-sky TESS space mission. Using projected rotational velocities, pulsation amplitudes and the number of pulsation modes, we devise a prioritised target list according to the mission requirements and the scientific potential of studying massive stars with the CubeSpec mission. The full CubeSpec target catalogue represents a modern review of spectral line profile and photometric variability properties among bright massive stars, which is highly complementary to BRITE mission light curve data.

description: Biometric technology has been increasingly deployed in the past decade, offering greater security and convenience than traditional methods of personal recognition. Although biometric signals' quality heavily affects a biometric system's performance, prior research on evaluating quality is limited. Quality is a critical issue in security, especially in adverse scenarios involving surveillance cameras, forensics, portable devices, or remote access through the Internet. This article analyzes what factors negatively impact biometric quality, how to overcome them, and how to incorporate quality measures into biometric systems. A review of the state of the art in these matters gives an overall framework for the challenges of biometric quality.

description: A large number of different lesions and pathologies can affect the human digestive system, resulting in life-threatening situations. Early detection plays a relevant role in the successful treatment and the increase of current survival rates to, e.g., colorectal cancer. The standard procedure enabling detection, endoscopic video analysis, generates large quantities of visual data that need to be carefully analyzed by an specialist. Due to the wide range of color, shape, and general visual appearance of pathologies, as well as highly varying image quality, such process is greatly dependent on the human operator experience and skill. In this work, we detail our solution to the task of multi-category classification of images from the gastrointestinal (GI) human tract within the 2020 Endotect Challenge. Our approach is based on a Convolutional Neural Network minimizing a hierarchical error function that takes into account not only the finding category, but also its location within the GI tract (lower/upper tract), and the type of finding (pathological finding/therapeutic intervention/anatomical landmark/mucosal views' quality). We also describe in this paper our solution for the challenge task of polyp segmentation in colonoscopies, which was addressed with a pretrained double encoder-decoder network. Our internal cross-validation results show an average performance of 91.25 Mathews Correlation Coefficient (MCC) and 91.82 Micro-F1 score for the classification task, and a 92.30 F1 score for the polyp segmentation task. The organization provided feedback on the performance in a hidden test set for both tasks, which resulted in 85.61 MCC and 86.96 F1 score for classification, and 91.97 F1 score for polyp segmentation. At the time of writing no public ranking for this challenge had been released.

description: We study the spectral classification of emission-line galaxies as star-forming galaxies or Active Galactic Nuclei (AGNs). From the Sloan Digital Sky Survey (SDSS) high quality data, we define an improved classification to be used for high redshift galaxies. We classify emission-line galaxies of the SDSS according to the latest standard recipe using [Oiii]5007, [Nii]6584, [Sii]6717+6731, H, and H emission lines. We obtain four classes: star-forming galaxies, Seyfert 2, LINERs, and composites. We then examine where these galaxies fall in the blue diagram used at high redshift (i.e. log([Oiii]5007/H) vs. log([Oii]3726+3729/H).We define new improved boundaries in the blue diagram for star-forming galaxies, Seyfert 2, LINERs, SF/Sy2, and SF-LIN/comp classes. We maximize the success rate to 99.7% for the detection of star-forming galaxies, to 86% for the Seyfert 2 (including the SF/Sy2 region), and to 91% for the LINERs. We also minimize the contamination to 16% in the region of star-forming galaxies. We cannot reliably separate composites from star-forming galaxies and LINERs, but we define a SF/LIN/comp region where most of them fall (64%).

K and B meson mixing in warped extra dimensions with custodial protection

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: After a brief theoretical introduction of the warped extra-dimensional model with custodial protection the results of arXiv:0809.1073 [hep-ph] are presented. In this work we analyze the impact of Kaluza-Klein (KK) gauge boson modes on Delta F=2 observables, for the first time considering the full operator basis and including NLO renormalization group running. It is pointed out that the dominant contribution in the B-system does not come from the KK gluon, but that contributions from KK excitations of the weak gauge bosons are competitive. In a numerical analysis we assess the amount of fine-tuning necessary for obtaining realistic values for quark masses and mixings and at the same time realistic values for epsilon_K, the measure for CP violation in K meson mixing. We are able to show that a mass of the lightest KK gauge boson of 2-3 TeV, and hence in the reach of the LHC, is still possible for moderate fine-tuning. These results enable us to make predictions for not yet measured Delta F=2 observables, such as S_ψϕand A_s^SL, which can differ significantly from their SM values.

A preliminary empirical investigation into imperialist theory
Creators: name: Dahl, Jeff
Publisher: name: University of British Columbia
Year: 2010

description: This study is a modest attempt, from a behavioural perspective, to sort out some of the conceptual difficulties in the imperialist literature. Several objections are raised pertaining to marxist determinism and a less deterministic model is opted for. The empirical implications of testing the whole model militate against it in a study of this size so that only two important propositions emanating from the model are tested; first that interactions in the international system are rank-dependent, and second, that they are feudally-structured. Support for these two hypotheses can be found in the behavioural literature, but the advantage of this study is that it offers an explanation - imperialism (with requisite qualifications) - for these interaction relationships. The results are far from conclusive; several problems regarding conceptual ambiguity remain. Future study rejecting the marxist mode of inquiry will have to concentrate on further specification of an alternative model.

description: For the design and optimization of CO2 recovery from alcoholic fermentation processes by distillation, models for vapor-liquid equilibria (VLE) are needed. Two such thermodynamic models, the Peng-Robinson equation of state (EOS) and a model based on Henry's law constants, are proposed for the ternary mixture N2+O2+CO2. Pure substance parameters of the Peng-Robinson EOS are taken from the literature, whereas the binary parameters of the Van der Waals one-fluid mixing rule are adjusted to experimental binary VLE data. The Peng-Robinson EOS describes both binary and ternary experimental data well, except at high pressures approaching the critical region. A molecular model is validated by simulation using binary and ternary experimental VLE data. On the basis of this model, the Henry's law constants of N2 and O2 in CO2 are predicted by molecular simulation. An easy-to-use thermodynamic model, based on those Henry's law constants, is developed to reliably describe the VLE in the CO2-rich region.

description: We have measured multi-band optical flux and colour variations for a sample of 12 low energy peaked blazars on short, day-to-month, timescales. Our sample contains six BL Lacertae objects and six flat spectrum radio quasars. These photometric observations, made during September 2008 to June 2009, used five optical telescopes, one in India and four in Bulgaria. We detected short term flux variations in eleven of these blazars and colour variability in eight of them. Our data indicate that six blazars (3C 66A, AO 0235+164, S5 0716+714, PKS 0735+178, OJ 287 and 3C 454.3) were observed in pre- or post-outburst states, that five (PKS 0420-014, 4C 29.45, 3C 279, PKS 1510-089 and BL Lac) were in a low state, while one (3C 273) was in an essentially steady state. The duty cycles for flux and colour variations on short timescales in these low energy peaked blazars are ~ 92 percent and ~ 33 percent, respectively. The colour vs magnitude correlations seen here support the hypothesis that BL Lac objects tend to become bluer with increase in brightness; however, flat spectrum radio quasars may show the opposite trend, and there are exceptions to these trends in both categories of blazar. We briefly discuss emission models for active galactic nuclei that might explain our results.

Magneto-asteroseismology of hot stars
Creators: name: Neiner, Coralie
Publisher: name: Zenodo
Year: 2024

description: Magnetic fields play a crucial role during the entire life of hot stars: they impact their birth, structure, rotation, pulsation, atmosphere, environment, binarity, evolution, and death, and thus next generations of stars and planets and galactic evolution. However, while our understanding of the surface magnetic properties has grown tremendously over the last decades, difficulties in correctly accounting for the effects of magnetic fields lead to large uncertainties in stellar evolution theory. Asteroseismology is the only existing technique for directly probing stellar interior processes, achieved via precise measurements of stellar pulsations. Magnetic field acts as a perturbation to the pulsation frequencies and lifts the degeneracy of different azimuthal orders into frequency multiplets. This enables the effective pulsation mode identification necessary for asteroseismic modeling, but also allows for a direct measurement of the magnetic field strength inside the star. The novel application of magneto-asteroseismology, i.e. combining asteroseismology and spectropolarimetry, thus provides crucial constraints on the physical ingredients of hot stars and on their evolutionary models. I will review the state-of-the art in magneto-asteroseismology of hot stars, recent progress in this field, and present the new MAESTROS international collaboration.

description: Thin films of TbMnO3 have been grown on SrTiO3 substrates. The films grow under compressive strain and are only partially clamped to the substrate. This produces remarkable changes in the magnetic properties and, unlike the bulk material, the films display ferromagnetic interactions below the ordering temperature of ~40K. X-ray photoemission measurements in the films show that the Mn-3s splitting is 0.3eV larger than that of the bulk. Ab initio embedded cluster calculations yield Mn-3s splittings that are in agreement with the experiment and reveal that the larger observed values are due to a larger ionicity of the films.

description: The pervasive phenomenon of friction has been studied at the nanoscale via a controlled manipulation of single atoms and molecules with a metallic tip, which enabled a precise determination of the static friction force necessary to initiate motion. However, little is known about the atomic dynamics during manipulation. Here, we reveal the complete manipulation process of a CO molecule on a Cu(110) surface at low temperatures using a combination of noncontact atomic force microscopy and density functional theory simulations. We found that an intermediate state, inaccessible for the far-tip position, is enabled in the reaction pathway for the close-tip position, which is crucial to understanding the manipulation process, including dynamic friction. Our results show how friction forces can be controlled and optimized, facilitating new fundamental insights for tribology.

description: Points of an orbit of a finite Coxeter group G, generated by n reflections starting from a single seed point, are considered as vertices of a polytope (G-polytope) centered at the origin of a real n-dimensional Euclidean space. A general efficient method is recalled for the geometric description of G- polytopes, their faces of all dimensions and their adjacencies. Products and symmetrized powers of G-polytopes are introduced and their decomposition into the sums of G-polytopes is described. Several invariants of G-polytopes are found, namely the analogs of Dynkin indices of degrees 2 and 4, anomaly numbers and congruence classes of the polytopes. The definitions apply to crystallographic and non-crystallographic Coxeter groups. Examples and applications are shown.

description: We investigate the properties of a special class of singular solutions for a self-gravitating perfect fluid in general relativity: the singular isothermal sphere. For arbitrary constant equation-of-state parameter $w=p/ρ$, there exist static, spherically-symmetric solutions with density profile $\propto 1/r^2$, with the constant of proportionality fixed to be a special function of $w$. Like black holes, singular isothermal spheres possess a fixed mass-to-radius ratio independent of size, but no horizon cloaking the curvature singularity at $r=0$. For $w=1$, these solutions can be constructed from a homogeneous dilaton background, where the metric spontaneously breaks spatial homogeneity. We study the perturbative structure of these solutions, finding the radial modes and tidal Love numbers, and also find interesting properties in the geodesic structure of this geometry. Finally, connections are discussed between these geometries and dark matter profiles, the double copy, and holographic entropy, as well as how the swampland distance conjecture can obscure the naked singularity.

description: In the face of the biodiversity crisis, concerted efforts towards understanding the effects of climate change and habitat loss and fragmentation, both locally and globally, are urgently needed. These are often attempted by leveraging the advances of modern genomics and bioinformatics methodologies. Especially in biodiversity hotspots, the need to understand, monitor and mitigate the loss of biodiversity is pivotal. Greece is a country with especially high endemism. A large percentage of its endemic species is threatened by climate change and human activities. To this end, the national academic community in biodiversity genomics has established a corresponding network of scientists from various Greek research institutes and universities covering different disciplines of biodiversity research.

 In these slides we are presenting the efforts of an established national Task Force that will channel the flow of information amongst researchers, policy makers, stakeholders and the local society. Our overarching goal is to build a sustainable community and infrastructure for the efficient management of the entire molecular biodiversity data cycle (i.e., from production and storage to the analysis and modelling of data, development of computational tools, and knowledge extraction). Using national and European infrastructures, such as ELIXIR and LifeWatch, we envision to set the ground for studying biodiversity through the lens of biodiversity genomics and offer evidence-based knowledge to guide management of the habitats and the biodiversity they host, as well as the implementation of appropriate policies.

description: We present the first data release of the MaNGA-ARO Survey of CO Targets (MASCOT), an ESO Public Spectroscopic Survey conducted at the Arizona Radio Observatory (ARO). We measure the CO(1-0) line emission in a sample of 187 nearby galaxies selected from the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey that has obtained integral field unit (IFU) spectroscopy for a sample of ~ 10,000 galaxies at low redshift. The main goal of MASCOT is to probe the molecular gas content of star-forming galaxies with stellar masses > 10^9.5 M_solar and with associated MaNGA IFU observations and well-constrained quantities like stellar masses, star formation rates and metallicities. In this paper we present the first results of the MASCOT survey, providing integrated CO(1-0) measurements that cover several effective radii of the galaxy and present CO luminosities, CO kinematics, and estimated H2 gas masses. We observe that the decline of galaxy star formation rate with respect to the star formation main sequence (SFMS) increases with the decrease of molecular gas and with a reduced star formation efficiency, in agreement with results of other integrated studies. Relating the molecular gas mass fractions with the slope of the stellar age gradients inferred from the MaNGA observations, we find that galaxies with lower molecular gas mass fractions tend to show older stellar populations close to the galactic center, while the opposite is true for galaxies with higher molecular gas mass fractions, providing tentative evidence for inside-out quenching.
description: 12 pages plus 20 pages of data tables and figures, accepted to MNRAS, data will be released as supplementary material with the paper as well as on the MASCOT website (https://wwwstaff.ari.uni-heidelberg.de/dwylezalek/mascot.html)
Wolf-Rayet Stars with BRITE
Creators: name: Moffat, Anthony
Publisher: name: Zenodo
Year: 2024

description: WR stars are massive stars characterized by their very strong but ~stable winds and include three categories: (1) classical He-rich, He-burning cWR stars evolved from O-stars with Mi ~ 20 - 60: Mo, (2) massive Main-Sequence WNh stars lying above O-stars in the HRD, with Mi > 60: and which owe their strong, broad emission lines to their high luminosity driving dense, hot winds, and (3) ~15% of central stars of planetary nebulae. (1) & (3) include WN stars dominated by spectral N lines from the CNO cycle (also (2)) and WC/O stars dominated by C and O from nuclear burning of He. Only the first and second categories include (Galactic) stars bright enough to be observed properly with BRITE; they are the subject of this talk about their variability.
