description: Barnard B1b has revealed as one of the most interesting globules from the chemical and dynamical point of view. It presents a rich molecular chemistry characterized by large abundances of deuterated and complex molecules. Furthermore, it hosts an extremely young Class 0 object and one candidate to First Hydrostatic Core (FHSC). Our aim was to determine the cosmic ray ionization rate and the depletion factors in this extremely young star forming region. We carried out a spectral survey towards Barnard 1b as part of the IRAM Large program ASAI using the IRAM 30-m telescope at Pico Veleta (Spain). This provided a very complete inventory of neutral and ionic C-, N- and S- bearing species with, up to our knowledge, the first secure detections of the deuterated ions DCS+ and DOCO+. We used a state-of-the-art pseudo-time-dependent gas-phase chemical model to determine the value of the cosmic ray ionization rate and the depletion factors. The observational data were well fitted with $ζ_{H_2}$ between 3E-17 s$^{-1}$ and 1E-16 s$^{-1}$. Elemental depletions were estimated to be ~10 for C and O, ~1 for N and ~25 for S. Barnard B1b presents similar depletions of C and O than those measured in pre-stellar cores. The depletion of sulfur is higher than that of C and O but not as extreme as in cold cores. In fact, it is similar to the values found in some bipolar outflows, hot cores and photon-dominated regions. Several scenarios are discussed to account for these peculiar abundances. We propose that it is the consequence of the initial conditions (important outflows and enhanced UV fields in the surroundings) and a rapid collapse (~0.1 Myr) that permits to maintain most S- and N-bearing species in gas phase to great optical depths. The interaction of the compact outflow associated with B1b-S with the surrounding material could enhance the abundances of S-bearing molecules, as well.

description: We investigate the cosmological applications of a bi-scalar modified gravity that exhibits partial conformal invariance, which could become full conformal invariance in the absence of the usual Einstein-Hilbert term and introducing additionally either the Weyl derivative or properly rescaled fields. Such a theory is constructed by considering the action of a non-minimally conformally-coupled scalar field, and adding a second scalar allowing for a nonminimal derivative coupling with the Einstein tensor and the energy-momentum tensor of the first field. At a cosmological framework we obtain an effective dark-energy sector constituted from both scalars. In the absence of an explicit matter sector we extract analytical solutions, which for some parameter regions correspond to an effective matter era and/or to an effective radiation era, thus the two scalars give rise to "mimetic dark matter" or to "dark radiation" respectively. In the case where an explicit matter sector is included we obtain a cosmological evolution in agreement with observations, that is a transition from matter to dark energy era, with the onset of cosmic acceleration. Furthermore, for particular parameter regions, the effective dark-energy equation of state can transit to the phantom regime at late times. These behaviours reveal the capabilities of the theory, since they arise purely from the novel, bi-scalar construction and the involved couplings between the two fields.

description: The purpose of the present paper is to provide an overview of Asymptotic-Preserving methods for multiscale plasma simulations by addressing three singular perturbation problems. First, the quasi-neutral limit of fluid and kinetic models is investigated in the framework of non magnetized as well as magnetized plasmas. Second, the drift limit for fluid descriptions of thermal plasmas under large magnetic fields is addressed. Finally efficient numerical resolutions of anisotropic elliptic or diffusion equations arising in magnetized plasma simulation are reviewed.

description: Nowadays, human movement in urban spaces can be traced digitally in many cases. It can be observed that movement patterns are not constant, but vary across time and space. In this work,we characterize such spatio-temporal patterns with an innovative combination of two separate approaches that have been utilized for studying human mobility in the past. First, by using non-negative tensor factorization (NTF), we are able to cluster human behavior based on spatio-temporal dimensions. Second, for understanding these clusters, we propose to use HypTrails, a Bayesian approach for expressing and comparing hypotheses about human trails. To formalize hypotheses we utilize data that is publicly available on the Web, namely Foursquare data and census data provided by an open data platform. By applying this combination of approaches to taxi data in Manhattan, we can discover and explain different patterns in human mobility that cannot be identified in a collective analysis. As one example, we can find a group of taxi rides that end at locations with a high number of party venues (according to Foursquare) on weekend nights. Overall, our work demonstrates that human mobility is not one-dimensional but rather contains different facets both in time and space which we explain by utilizing online data. The findings of this paper argue for a more fine-grained analysis of human mobility in order to make more informed decisions for e.g., enhancing urban structures, tailored traffic control and location-based recommender systems.

Mental Activity as the Bridge between Neural Biomarkers and Symptoms of Psychiatric Illness

Publisher: name: SAGE Publications Ltd
Year: 2022

description: The Research Domain Criteria (RDoC) initiative challenges researchers to build neurobehavioral models of psychiatric illness with the hope that such models identify better targets that will yield more effective treatment. However, a guide for building such models was not provided and symptom heterogeneity within Diagnostic Statistical Manual categories has hampered progress in identifying endophenotypes that underlie mental illness. We propose that the best chance to discover viable biomarkers and treatment targets for psychiatric illness is to investigate a triangle of relationships: severity of a specific psychiatric symptom that correlates to mental activity that correlates to a neural activity signature. We propose that this is the minimal model complexity required to advance the field of psychiatry. With an understanding of how neural activity relates to the experience of the patient, a genuine understanding for how treatment imparts its therapeutic effect is possible. After the discovery of this three-fold relationship, causal testing is required in which the neural activity pattern is directly enhanced or suppressed to provide causal, instead of just correlational, evidence for the biomarker. We suggest using non-invasive brain stimulation (NIBS) as these techniques provide tools to precisely manipulate spatial and temporal activity patterns. We detail how this approach enabled the discovery of two orthogonal electroencephalography (EEG) activity patterns associated with anhedonia and anxiosomatic symptoms in depression that can serve as future treatment targets. Altogether, we propose a systematic approach for building neurobehavioral models for dimensional psychiatry.

description: We present experimental results on the observation of a bulk second-order nonlinear susceptibility derived from both free-space and integrated measurements in silicon nitride. Phase-matching is achieved through dispersion engineering of the waveguide cross-section, independently revealing multiple components of the nonlinear susceptibility, namely X(2)yyy and X(2)xxy. Additionally, we show how the generated second-harmonic signal may be actively tuned through the application of bias voltages across silicon nitride. The nonlinear material properties measured here are anticipated to allow for the practical realization of new nanophotonic devices in CMOS-compatible silicon nitride waveguides, adding to their viability for telecommunication, data communication, and optical signal processing applications.
Glial cells as reparative targets for radiative damage to the nervous system

Year: 2022

description: Disorders of the nervous system (NS) impact millions of adults, worldwide, as a consequence of traumatic injury, genetic illness, or chronic health conditions. Contemporary studies have begun to incorporate neuroglia into emerging NS therapies to harness the regenerative potential of glial‐mediated synapses in the brain, the spinal cord, and the retina. Neuroglia are found across the entire NS, the Central Nervous System (CNS) consisting of the brain and spinal cord, and the Peripheral Nervous System (PNS) extending to the rest of the body. Within the CNS also exists the optic nerve and retina. Glial cells are known to provide structural support, homeostasis, differentiation, and more. Ensheathing much of the NS are the meninges, which carry cerebrospinal fluid (CSF) within the subarachnoid space (SAS). CSF is understood to provide support to the brain by providing neutral buoyancy and cushioning against trauma. The flow of CSF circulates essential polypeptides, metabolites, and growth factors that directly impact neural response and recovery via signaling with healthy glia. However, the SAS can become damaged via radiation, causing CSF to leak into nearby neural tissue. With the need for reparative targets to the nervous system, we investigated the innate restorative responses of neuroglia. Our first study illustrated the effects of CSF on non-myelinating Schwann cells of the neuromuscular junction and showed chemotactic behaviors in response to brain-derived neurotrophic factor (BDNF) for neural therapies. Our second study examined the effects of ionic irradiation on Muller Glia and their neuroprotective responses. This study examined the use of antioxidants as radiation countermeasures and was further enhanced by use of NASA’s galactic cosmic ray (GCR) to simulate cosmic ionizing radiation in low and high radiation dose parameters. MG behaviors were studied in response to varying radiation doses and changes in survival and ROS production were measured. Our studies together illustrate the significance of examining neuroglia as therapeutic targets for neurological disorders.

description: In order to support better discoverability and FAIR data, the Association of European University Presses has partnered with ScienceOpen to launch a new book catalogue for their member presses based solely on DOIs and their associated metadata. Using DOIs as persistent identifiers for books and chapters is essential for citation tracking, aggregation in discovery environments, and alternative metrics It is a central tenant of the FAIR data principles. Nevertheless, adoption of DOIs for books is relatively low. With this new catalogue ScienceOpen and the AEUP will highlight books by members with best practices around DOIs. But they will also provide a support structure for member presses with no DOIs or only very basic levels of metadata richness. Member presses are welcome to use the free platform BookMetaHub to enrich metadata or convert metadata in ONIX XML formats into Crossref-ready XML records. The BookMetaHub, funded by a grant from the Germany Ministry for Education and Research, offers an interface to add further persistent identifiers such as BISAC codes, ORCID IDs for authors, ROR IDs for institutions, and FundRef IDs via the Crossref Funder Registry.

description: The idea that the success rate of a team increases when playing home is broadly accepted and documented for a wide variety of sports. Investigations on the so-called home advantage phenomenon date back to the 70's and every since has attracted the attention of scholars and sport enthusiasts. These studies have been mainly focused on identifying the phenomenon and trying to correlate it with external factors such as crowd noise and referee bias. Much less is known about the effects of home advantage in the microscopic dynamics of the game (within the game) or possible team-specific and evolving features of this phenomenon. Here we present a detailed study of these previous features in the National Basketball Association (NBA). By analyzing play-by-play events of more than sixteen thousand games that span thirteen NBA seasons, we have found that home advantage affects the microscopic dynamics of the game by increasing the scoring rates and decreasing the time intervals between scores of teams playing home. We verified that these two features are different among the NBA teams, for instance, the scoring rate of the Cleveland Cavaliers team is increased 0.16 points per minute (on average the seasons 2004-05 to 2013-14) when playing home, whereas for the New Jersey Nets (now the Brooklyn Nets) this rate increases in only 0.04 points per minute. We further observed that these microscopic features have evolved over time in a non-trivial manner when analyzing the results team-by-team. However, after averaging over all teams some regularities emerge; in particular, we noticed that the average differences in the scoring rates and in the characteristic times (related to the time intervals between scores) have slightly decreased over time, suggesting a weakening of the phenomenon.

Landscape Learning in Colonial Australia: Technologies of Water Management on the Central Highlands Goldfields
Creators: name: Lawrence, Susan
name: Davies, Peter
Publisher: name: La Trobe
Year: 2023

description: Water was a crucial but often limited resource on the goldfields of central Victoria in the nineteenth century, and miners quickly developed a range of techniques to respond to water scarcity. This paper uses a landscape learning model to examine these human/environmental interactions in the recent past. It combines archaeological and historical evidence to understand and interpret cultural changes to natural landscapes, especially in relation to water management in colonial Australia. A range of archaeological features preserved in the landscape reveal responses to the challenges posed by climate and topography when capturing, storing, transporting and using water for industrial, agricultural and domestic purposes. Water in this context provides a focus for exploring the complex relationships between people and the natural world, integrating evidence of small-scale, local activities with broader transformations of physical environments.

description: Differences in attitudes on social issues such as abortion, immigration and sex are hugely divisive, and understanding their origins is among the most important tasks facing human behavioural sciences. Despite the clear psychological importance of parenthood and the motivation to provide care for children, researchers have only recently begun investigating their influence on social and political attitudes. Because socially conservative values ostensibly prioritize safety, stability and family values, we hypothesized that being more invested in parental care might make socially conservative policies more appealing. Studies 1 (pre-registered; n = 376) and 2 (n = 1924) find novel evidence of conditional experimental effects of a parenthood prime, such that people who engaged strongly with a childcare manipulation showed an increase in social conservatism. Study 3 (n = 2610, novel data from 10 countries) and 4 (n = 426 444, World Values Survey data) find evidence that both parenthood and parental care motivation are associated with increased social conservatism around the globe. Further, most of the positive association globally between age and social conservatism is accounted for by parenthood. These findings support the hypothesis that parenthood and parental care motivation increase social conservatism.
Helical turbulent Prandtl number in the $A$ model of passive advection: Two loop approximation

description: Using the field theoretic renormalization group technique in the two-loop approximation, turbulent Prandtl numbers are obtained in the general $A$ model of passive vector advected by fully developed turbulent velocity field with violation of spatial parity introduced via continuous parameter $ρ$ ranging from $ρ=0$ (no violation of spatial parity) to $|ρ|=1$ (maximum violation of spatial parity). In non-helical environments, we demonstrate that $A$ is restricted to $-1.723 \leq A \leq 2.800$ (rounded on the last presented digit) due to the constraints of two-loop calculations. When $ρ>0.749$ restrictions may be removed. Furthermore, three physically important cases $A \in \{-1, 0, 1\}$ are shown to lie deep within the allowed interval of $A$ for all values of $ρ$. For the model of linearized Navier-Stokes equations ($A = -1$) up to date unknown helical values of turbulent Prandtl number have been shown to equal $1$ regardless of parity violation. Furthermore, we have shown that interaction parameter $A$ exerts strong influence on advection diffusion processes in turbulent environments with broken spatial parity. In explicit, depending on actual value of $A$ turbulent Prandtl number may increase or decrease with $ρ$. By varying $A$ continuously we explain high stability of kinematic MHD model ($A=1$) against helical effects as a result of its closeness to $A = 0.912$ (rounded on the last presented digit) case where helical effects are completely suppressed. Contrary, for the physically important $A=0$ model we show that it lies deep within the interval of models where helical effects cause the turbulent Prandtl number to decrease with $|ρ|$. We thus identify internal structure of interactions given by parameter $A$, and not the vector character of the admixture itself to be the dominant factor influencing diffusion advection processes in the helical $A$ model.

description: Based on observations performed with the Pulkovo normal astrograph in 2008-2015 and data from sky surveys (DSS, 2MASS, SDSS DR12, WISE), we have investigated the motions of 1308 stars with proper motions larger than 300 mas/yr down to magnitude 17. The main idea of our search for binary stars based on this material is reduced to comparing the quasi-mean (POSS2-POSS1; an epoch difference of $\approx$50 yr) and quasi-instantaneous (2MASS, SDSS, WISE, Pulkovo; an epoch difference of $\approx$10 yr) proper motions. If the difference is statistically significant compared to the proper motion errors, then the object may be considered as a Δμ-binary candidate. One hundred and twenty one stars from among those included in the observational program satisfy this requirement. Additional confirmations of binarity for a number of stars have been obtained by comparing the calculated proper motions with the data from several programs of stellar trigonometric parallax determinations and by analyzing the asymmetry of stellar images on sky-survey CCD frames. Analysis of the highly accurate SDSS photometric data for four stars (J0656+3827, J0838+3940, J1229+5332, J2330+4639) allows us to reach a conclusion about the probability that these Δμ binaries are white dwarf + M dwarf pairs.

description: In a world where all societal and scientific challenges are intertwined, it is urgent to launch multidisciplinary initiatives and projects so that scientists from different domains can collaborate. In order to carry out multidisciplinary projects, it becomes essential to develop gateways between metadata standards that will allow the matching of data representations designed for different domains. The opening of these gateways is therefore necessary for developing services across the disciplines, which is a key concept in the EOSC interoperability framework and the focus of the FAIR-EASE project. FAIR-EASE focuses on opening these gateways for the earth and environmental sciences, which require a large volume of data from sources such as satellite, in-situ observations, models, and even omics experiments. Earth system domains are interconnected, but the present digital architecture is based essentially on distributed and domain-dependent data repositories inducing real difficulties for integrated uses of all the environmental data. This creates barriers for several studies with large societal impacts, such as climate change, agriculture and food, human safety and health. To go beyond this state-of-the-art, the overall objective of FAIR-EASE is to customize and operate distributed and integrated services for observation and modelling of the Earth system, environment and biodiversity by improving their different components implemented in close cooperation with user-communities, the European Open Science Cloud (EOSC) and research infrastructures in their design and sustainable availability. FAIR-EASE offers two services: the FAIR-EASE Interdisciplinary Data Discovery and Access service, that will provide users with an easy and FAIR service for discovery of and access to multidisciplinary and aggregated data sets, and the Earth Analytic Lab, that will provide users with an easy way to visualise, analyse and process environmental data on-demand, that is, according to their specific objectives, thematic, geographical areas and time periods of interest. Earth and Environmental scientific communities are involved through the development of three multidisciplinary Use Cases that will define the community requirements from real-life science challenges.

description: For years couples undergoing in vitro fertilization (IVF) have been able to access preimplantation genetic testing (PGT) for aneuploidy, chromosomal rearrangements, and monogenic conditions. Screening embryos for polygenic conditions such as diabetes, cancer and cardiovascular risk has not been available until more recent years. PGT for polygenetic conditions (PGT-P) has been made possible with advancements in technology and increasing available data from genome wide association studies (GWAS). As is common with new technology, there has been push back from some calling its use controversial, however many patients have opted into this technology with hopes that it would provide them useful information when selecting an embryo to transfer and allow them to transfer the healthiest embryo possible. Our research investigates these patients’ motivations to use PGT-P and the decision-making factors that they considered during this process. Our study found that the PGT-P result was a valuable tool for our patients as it was ranked highly when selecting an embryo to transfer. Additionally, patients had minimal feelings of decision regret upon reflecting on their decision to opt into PGT-P. This provides the first source of data directly from patients that have used the technology and is exciting insight into the patient experience with PGT-P.

description: Octupole vibrations are studied in some doubly magic nuclei using the time-dependent Hartree-Fock (TDHF) theory with a Skyrme energy density functional. Through the use of the linear response theory, the energies and transition amplitudes of the low-lying vibrational modes for each of the nuclei were determined. Energies were found to be close to experimental results. However, transition amplitudes, quantified by the deformation parameter $β_3$, are underestimated by TDHF. A comparison with single-particle excitations on the Hartree-Fock ground-state shows that the collective octupole vibrations have their energy lowered due to attractive RPA residual interaction.

Senses of humor: joking etiquette in African American literature at the turn of the century
Creators: name: Ozier, Amadi Iruka
Publisher: name: No Publisher Supplied
Year: 2022

description: African American humor in part borrowed its vocabularies, forms, and thematics from contemporaneous debates about Black respectability politics, which sought to improve Black social conditions by performing bourgeois notions of propriety. In that sense, African American humor was informed by the same social processes that courted New Negro values of exemplarity, collectivity, and intelligence. Black literature criticism and African American historiography has often stressed the anti-humor dimensions of uplift work at the turn of the century. This project reveals that Black writers used humor, particularly irony, to model New Negro values (“good sense”) and distance themselves from the specter of minstrelsy. By using humor theory to delineate respectability discourse’s ideological and aesthetic features, I reclaim subtlety as an overlooked feature of Black art and performance, fundamentally shifting how we understand Black racial uplift work. Ultimately, I argue that Black humorists used irony to index cultural anxieties about Black representation for both intraracial and interracial readerships amid the development of an emerging Black American middle class.

description: Principal component analysis (PCA) is a widely used method for dimension reduction. In high dimensional data, the "signal" eigenvalues corresponding to weak principal components (PCs) do not necessarily separate from the bulk of the "noise" eigenvalues. Therefore, popular tests based on the largest eigenvalue have little power to detect weak PCs. In the special case of the spiked model, certain tests asymptotically equivalent to linear spectral statistics (LSS)---averaging effects over all eigenvalues---were recently shown to achieve some power. We consider a nonparametric, non-Gaussian generalization of the spiked model to the setting of Marchenko and Pastur (1967). This allows a general bulk of the noise eigenvalues, accomodating correlated variables even under the null hypothesis of no significant PCs. We develop new tests based on LSS to detect weak PCs in this model. We show using the CLT for LSS that the optimal LSS satisfy a Fredholm integral equation of the first kind. We develop algorithms to solve it, building on our recent method for computing the limit empirical spectrum. In contrast to the standard spiked model, we find that under "widely spread" null eigenvalue distributions, the new tests have a lot of power.

description: Accurate knowledge of fission fragment yields is an essential ingredient of numerous applications ranging from the formation of elements in the r-process to fuel cycle optimization for nuclear energy. The need for a predictive theory applicable where no data is available is an incentive to develop a fully microscopic approach to fission dynamics. In this work, we calculate the pre-neutron emission charge and mass distributions of the fission fragments formed in the neutron-induced fission of 239Pu using a microscopic method based on nuclear energy density functional (EDF) method, where large amplitude collective motion is treated adiabatically using the time dependent generator coordinate method (TDGCM) under the Gaussian overlap approximation (GOA). Fission fragment distributions are extracted from the flux of the collective wave packet through the scission line. We find that the main characteristics of the fission charge and mass distributions can be well reproduced by existing energy functionals even in two-dimensional collective spaces. Theory and experiment agree typically within 2 mass units for the position of the asymmetric peak. As expected, calculations are sensitive to the structure of the initial state and the prescription for the collective inertia. We emphasize that results are also sensitive to the continuity of the collective landscape near scission. Our analysis confirms that the adiabatic approximation provides an effective scheme to compute fission fragment yields. It also suggests that, at least in the framework of nuclear DFT, three-dimensional collective spaces may be a prerequisite to reach 10% accuracy in predicting pre-neutron emission fission fragment yields.

description: Recognizing Open Science as a true game-changer in addressing the pressing planetary and socio-economic challenges, UNESCO led a global dialogue with the aim of developing the first international standard-setting instrument on Open Science in the form of a UNESCO Recommendation since 2019. The UNESCO Recommendation on Open Science, unanimously adopted on 23 November 2021 by 193 UNESCO Member States defines shared values and principles for Open Science and identifies concrete measures on open access and open data, with proposals to bring society closer to science and commitments to facilitate the production and dissemination of scientific knowledge worldwide. If adequately implemented across the world and by different open science actors, the Recommendation has the potential of significantly advancing science that is more accessible, collaborative, transparent, inclusive and more responsive to the needs of society.

description: In this work, we perform an aposteriori error analysis on implicit and explicit large eddy simulation closure models for solving the Burgers turbulence problem. Our closure modeling efforts include both functional and structural models equipped with various low-pass filters. We introduce discrete binomial smoothing filters and an enhanced version of the Van Cittert algorithm to accelerate the convergence of approximate deconvolution processes including regularization and relaxation filtering approaches. Our implicit modeling efforts consist of various high-order schemes including compact and non-compact fifth-order upwind schemes as well as weighted essential non-oscillatory (WENO) and compact reconstructed WENO (CRWENO) schemes, and the resulting schemes are shown to effectively converge to the direct numerical simulation (DNS) for increasing resolutions. Comparing with DNS and underresolved DNS computations, our numerical assessments illustrate the ability of these methods to capture the energy content near grid cut-off scale.
How researchers share data? Four case studies from the Gdańsk University of Technology

description: The Gdańsk University of Technology Library participated in the open call project for interdisciplinary research adoption grants funded by the EOSC Future using the RDA Open Call mechanism. One of the goals was to create an overview and thematic analysis related to open data curation and sharing. Our case studies focus on four scientific disciplines represented at the Gdańsk Tech that might be useful in the international context: architecture, civil engineering, economics and natural language processing. The main reasons for choosing those particular disciplines were that they are still not so advanced in disseminating data at the national and the international level, they do not have robust data management practices, and sharing data is often difficult due to copyright issues, making it difficult this analysis challenging and very interesting. Each scientific discipline has its scholarly communication practices and should be treated individually concerning the maintaining regulations and procedures following the research data issues. Conversely, specific data types need a particular approach to maintain them, especially concerning licensing, preservation and sharing. Our poster shows the overview and challenges of data-sharing practices within architecture, civil engineering, economics and natural language processing, as well as any possible cooperation between disciplines. The poster aims to describe the opportunities for data sharing in diverse disciplines, workflow practices in data management, implementation of metadata standards, and the social aspect of sharing data, such as researchers' attitudes and discipline-specific traditions. Work is based on four semi-structured interviews. Collected data was analysed and documented graphically to illustrate the four disciplines' most critical procedures and requirements for data management. In addition, the poster includes a model example of a dataset for each scientific discipline deposited in our university data repository (MOST WIEDZY Open Research Data Catalogue).

description: Материал, представленный в статье, продолжает серию работ автора в аспекте исследования вопросов общества и полиции, его взаимодействии и доверии. Автор считает, что доверительное отношение общества к полиции – это основа благополучия в стране. Сложившиеся стереотипы относительно полиции в умах простых обывателей негативно сказываются на формировании доверительного отношения к этому социальному институту. Автор предлагает оптимизировать структуру полиции в направлении повышения качества ее деятельности. Реализация данного направления автору статьи видится в необходимости создания как можно большего числа положительных прецедентов взаимодействия общества с полицией. С этой целью предлагается высвечивать положительные моменты в деятельности полиции через средства массовой информации, кинематограф, литературные произведения. Только так, считает автор, можно создать культурный продукт, способный если не устранить, то минимизировать негативные стереотипы, годами формировавшиеся в умах простых людей.

description: Spitzer microlensing parallax observations of OGLE-2015-BLG-1212 decisively breaks a degeneracy between planetary and binary solutions that is somewhat ambiguous when only ground-based data are considered. Only eight viable models survive out of an initial set of 32 local minima in the parameter space. These models clearly indicate that the lens is a stellar binary system possibly located within the bulge of our Galaxy, ruling out the planetary alternative. We argue that several types of discrete degeneracies can be broken via such space-based parallax observations.

Fixed point indices of planar continuous maps

description: We characterize the sequences of fixed point indices $\{i(f^n, p)\}_{n\ge 1}$ of fixed points that are isolated as an invariant set and continuous maps in the plane. In particular, we prove that the sequence is periodic and $i(f^n, p) \le 1$ for every $n \ge 1$. This characterization allows us to compute effectively the Lefschetz zeta functions for a wide class of continuous maps in the 2-sphere, to obtain new results of existence of infinite periodic orbits inspired on previous articles of J. Franks and to give a partial answer to a problem of Shub about the growth of the number of periodic orbits of degree--$d$ maps in the 2-sphere.

description: Neuroinflammation (NI) is a key player in neurodegenerative diseases, such as multiple sclerosis (MS). Magnetic resonance imaging is the gold standard imaging method for diagnosis of MS, however, better diagnostic tools are needed for the follow-up of disease progression, earlier diagnosis, and assessment of patients’ response to therapy. Positron emission tomography (PET) is a sensitive and selective functional imaging method for investigating mechanisms of diseases at a molecular level. NI can be visualised in PET by targeting the 18 kDa translocator protein (TSPO), which is upregulated during NI on the mitochondria of glial cells. This study aimed to evaluate the properties of [18F]GE-180, a 2nd generation TSPO PET radiotracer, in a unilateral model of acute NI and evaluate the efficacy of immunomodulatory drugs, anti-VLA-4 and dimethyl fumarate (DMF), in two different focal rat models of experimental autoimmune encephalomyelitis (EAE), the fDTH-EAE and fMOG-EAE models. The applied methods were in vivo PET imaging, digital autoradiography, and immunohistochemical (IHC) staining. Study I indicated improved binding potential of [18F]GE-180 over the 1st generation tracer [11C]PK11195 and showed that the unilateral model of acute NI is suitable for the evaluation of novel PET tracers of NI. Study II indicated that anti-VLA-4 had no short-term treatment effects in the fDHT-EAE-rat model. However, discontinuation of the treatment caused a rebound that could be detected with [18F]GE-180. Study III showed, that short-term, but not long-term, DMF treatment decreases uptake of [18F]GE-180 in the fDTH-EAE rat model, and no rebound effect was detected after halting the treatment for 10 weeks. Nevertheless, the efficacy of DMF was detected using IHC for CD4+ and CD8+ cells. No DMF treatment effect was observed in the fMOG-EAE model. In conclusion, focal animal models of NI are applicable for evaluating novel PET tracers. Furthermore, efficacy assessment of immunomodulatory drugs can be evaluated using TSPO PET when the tracer is binding to the same biomarker that the drug is affecting.
