description: The NMR technique is quite essential as it permits atomic scale measurements in materials. The aim of this article is to present the main parameters accessible to NMR experiments and to relate them to the electronic properties of simple solids in which electronic correlations are not dominant. It will be shown that in metals the Pauli paramagnetism, that is the electronic density of states is accessible through NMR shift and spin lattice relaxation data. Those permit as well to determine electronic gaps in some electronic structures, or in the SC state. The capability to reveal by NMR the incidence of impurities and disorder is also underlined. A complementary article will be dedicated to the specific properties of strongly correlated materials which have been revealed and studied by NMR experiments.

description: We derive scaling relations for the extension statistics and the confinement free energy for a semi-flexible polymer confined to a channel with a rectangular cross-section. Our motivation are recent numerical results [Gupta {\em et al.}, JCP {\bf 140} (2014) 214901] indicating that extensional fluctuations are quite different in rectangular channels compared to square channels. Our results are of direct relevance for interpreting current experiments on DNA molecules confined to nano-channels, as many experiments are performed for rectangular channels with large aspect ratios while theoretical and simulation results are usually obtained for square channels.

description: Recent advances in deep learning have improved the segmentation accuracy of subcortical brain structures, which would be useful in neuroimaging studies of many neurological disorders. However, most existing deep learning based approaches in neuroimaging do not investigate the specific difficulties that exist in segmenting extremely small but important brain regions such as the subnuclei of the amygdala. To tackle this challenging task, we developed a dual-branch dilated residual 3D fully convolutional network with parallel convolutions to extract more global context and alleviate the class imbalance issue by maintaining a small receptive field that is just the size of the regions of interest (ROIs). We also conduct multi-scale feature fusion in both parallel and series to compensate the potential information loss during convolutions, which has been shown to be important for small objects. The serial feature fusion enabled by residual connections is further enhanced by a proposed top-down attention-guided refinement unit, where the high-resolution low-level spatial details are selectively integrated to complement the high-level but coarse semantic information, enriching the final feature representations. As a result, the segmentations resulting from our method are more accurate both volumetrically and morphologically, compared with other deep learning based approaches. To the best of our knowledge, this work is the first deep learning-based approach that targets the subregions of the amygdala. We also demonstrated the feasibility of using a cycle-consistent generative adversarial network (CycleGAN) to harmonize multi-site MRI data, and show that our method generalizes well to challenging traumatic brain injury (TBI) datasets collected from multiple centers. This appears to be a promising strategy for image segmentation for multiple site studies and increased morphological variability from significant brain pathology.

description: Cerebrospinal fluid (CSF) plays an essential role in early postnatal brain development. Extra-axial CSF (EA-CSF) volume, which is characterized by CSF in the subarachnoid space surrounding the brain, is a promising marker in the early detection of young children at risk for neurodevelopmental disorders. Previous studies have focused on global EA-CSF volume across the entire dorsal extent of the brain, and not regionally-specific EA-CSF measurements, because no tools were previously available for extracting local EA-CSF measures suitable for localized cortical surface analysis. In this paper, we propose a novel framework for the localized, cortical surface-based analysis of EA-CSF. The proposed processing framework combines probabilistic brain tissue segmentation, cortical surface reconstruction, and streamline-based local EA-CSF quantification. The quantitative analysis of local EA-CSF was applied to a dataset of typically developing infants with longitudinal MRI scans from 6 to 24 months of age. There was a high degree of consistency in the spatial patterns of local EA-CSF across age using the proposed methods. Statistical analysis of local EA-CSF revealed several novel findings: several regions of the cerebral cortex showed reductions in EA-CSF from 6 to 24 months of age, and specific regions showed higher local EA-CSF in males compared to females. These age-, sex-, and anatomically-specific patterns of local EA-CSF would not have been observed if only a global EA-CSF measure were utilized. The proposed methods are integrated into a freely available, open-source, cross-platform, user-friendly software tool, allowing neuroimaging labs to quantify local extra-axial CSF in their neuroimaging studies to investigate its role in typical and atypical brain development.

description: The Gaia-ESO Survey (GES) is a large public spectroscopic survey at the European Southern Observatory Very Large Telescope. A key aim is to provide precise radial velocities (RVs) and projected equatorial velocities (v sin i) for representative samples of Galactic stars, that will complement information obtained by the Gaia astrometry satellite. We present an analysis to empirically quantify the size and distribution of uncertainties in RV and v sin i using spectra from repeated exposures of the same stars. We show that the uncertainties vary as simple scaling functions of signal-to-noise ratio (S/N) and v sin i, that the uncertainties become larger with increasing photospheric temperature, but that the dependence on stellar gravity, metallicity and age is weak. The underlying uncertainty distributions have extended tails that are better represented by Student's t-distributions than by normal distributions. Parametrised results are provided, that enable estimates of the RV precision for almost all GES measurements, and estimates of the v sin i precision for stars in young clusters, as a function of S/N, v sin i and stellar temperature. The precision of individual high S/N GES RV measurements is 0.22-0.26 km/s, dependent on instrumental configuration.

description: I launched The Little Mountain Project as a response to the eviction and destruction of a social housing community in Vancouver, Canada. Utilizing hybrid digital media practices, my work encourages citizens to meet and participate in democratic processes. The main components of this new media exploration consist of a blog and video archive, a multi-platform signage project, and a collaborative community web history project. This paper documents the development of a methodology for an innovative documentary practice – a hyperlocal web-based strategy – to empower a counter public and to facilitate community dialogue around rapidly evolving civic processes. I situate my practice within a critique of neoliberalism, the idea of the “public sphere,” and the history of advocacy and activist filmmaking in Canada, in particular, the National Film Board of Canada’s “Challenge for Change Program,”1 a ground-breaking experiment in the use of film for the purpose of social activism. The Little Mountain Project aims to explore new forms of social, political, and cultural production within emergent practices enabled by web-based media, which propose new ways to facilitate dialogue within the public sphere.

description: Marrow adipose tissue (MAT) and its relevance to skeletal health during caloric restriction (CR) is unknown: It remains unclear whether exercise, which is anabolic to bone in a calorie-replete state, alters bone or MAT in CR. We hypothesized that response of bone and MAT to exercise in CR differs from the calorie-replete state. Ten-week-old female B6 mice fed a regular diet (RD) or 30% CR diet were allocated to sedentary (RD, CR, n = 10/group) or running exercise (RD-E, CR-E, n = 7/group). After 6 weeks, CR mice weighed 20% less than RD, p < 0.001; exercise did not affect weight. Femoral bone volume (BV) via 3D MRI was 20% lower in CR versus RD (p < 0.0001). CR was associated with decreased bone by μCT: Tb.Th was 16% less in CR versus RD, p < 0.003, Ct.Th was 5% less, p < 0.07. In CR-E, Tb.Th was 40% less than RD-E, p < 0.0001. Exercise increased Tb.Th in RD (+23% RD-E versus RD, p <; 0.003) but failed to do so in CR. Cortical porosity increased after exercise in CR (+28%, p = 0.04), suggesting exercise during CR is deleterious to bone. In terms of bone fat, metaphyseal MAT/ BV rose 159% in CR versus RD, p = 0.003 via 3D MRI. Exercise decreased MAT/BV by 52% in RD, p < 0.05, and also suppressed MAT in CR (−121%, p = 0.047). Histomorphometric analysis of adipocyte area correlated with MAT by MRI (R2 = 0.6233, p < 0.0001). With respect to bone, TRAP and Sost mRNA were reduced in CR. Intriguingly, the repressed Sost in CR rose with exercise and may underlie the failure of CR-bone quantity to increase in response to exercise. Notably, CD36, a marker of fatty acid uptake, rose 4088% in CR (p < 0.01 versus RD), suggesting that basal increases in MAT during calorie restriction serve to supply local energy needs and are depleted during exercise with a negative impact on bone.

description: In this article the effect of noise on Grover's algorithm is analyzed, modeled as a total depolarizing channel (TDCh) and a local depolarizing channel in each qubit (LDCh). The focus was not in error correction (e.g. by the fault-tolerant method), but to provide an insight to the kind of error, or degradation, that needs to be corrected. In the last years analytical results regarding mainly the TDCh model have been obtained. In this paper we extend these previous results to the local case, concluding that the degradation of Grover's algorithm with the latter is worse than the former. It has been shown that for both cases with an $N$-dependent small enough error-width, smaller than $1/\sqrt{N}$ for total error and $1/(\sqrt{N}\log_2{N})$ for the local case, correction is not needed.

description: BACKGROUND: Genetic variation in the guidance cue DCC gene is linked to psychopathologies involving dysfunction in the prefrontal cortex. We created an expression-based polygenic risk score (ePRS) based on the DCC coexpression gene network in the prefrontal cortex, hypothesizing that it would be associated with individual differences in total brain volume. METHODS: We filtered single nucleotide polymorphisms (SNPs) from genes coexpressed with DCC in the prefrontal cortex obtained from an adult postmortem donors database (BrainEAC) for genes enriched in children 1.5 to 11 years old (BrainSpan). The SNPs were weighted by their effect size in predicting gene expression in the prefrontal cortex, multiplied by their allele number based on an individual's genotype data, and then summarized into an ePRS. We evaluated associations between the DCC ePRS and total brain volume in children in 2 community-based cohorts: the Maternal Adversity, Vulnerability and Neurodevelopment (MAVAN) and University of California, Irvine (UCI) projects. For comparison, we calculated a conventional PRS based on a genome-wide association study of total brain volume. RESULTS: Higher ePRS was associated with higher total brain volume in children 8 to 10 years old (β = 0.212, p = 0.043; n = 88). The conventional PRS at several different thresholds did not predict total brain volume in this cohort. A replication analysis in an independent cohort of newborns from the UCI study showed an association between the ePRS and newborn total brain volume (β = 0.101, p = 0.048; n = 80). The genes included in the ePRS demonstrated high levels of coexpression throughout the lifespan and are primarily involved in regulating cellular function. LIMITATIONS: The relatively small sample size and age differences between the main and replication cohorts were limitations. CONCLUSION: Our findings suggest that the DCC coexpression network in the prefrontal cortex is critically involved in whole brain development during the first decade of life. Genes comprising the ePRS are involved in gene translation control and cell adhesion, and their expression in the prefrontal cortex at different stages of life provides a snapshot of their dynamic recruitment.

description: Structural neural network architecture patterns in the human brain could be related to individual differences in phenotype, behavior, genetic determinants, and clinical outcomes from neuropsychiatric disorders. Recent studies have indicated that a personalized neural (brain) fingerprint can be identified from structural brain connectomes. However, the accuracy, reproducibility and translational potential of personalized fingerprints in terms of cognition is not yet fully determined. In this study, we introduce a dynamic connectome modeling approach to identify a critical set of white matter subnetworks that can be used as a personalized fingerprint. Several individual variable assessments were performed that demonstrate the accuracy and practicality of personalized fingerprint, specifically predicting the identity and IQ of middle age adults, and the developmental quotient in toddlers. Our findings suggest the fingerprint found by our dynamic modeling approach is sufficient for differentiation between individuals, and is also capable of predicting general intellectual ability across human development. © 2020 The AuthorsSignificance Statement We demonstrate that white matter connections obtained from high resolution medical imaging data form a personalized fingerprint is capable of estimating individual identity and neurodevelopmental variables across human life-span. This important finding provides strong evidence to support the concept of neurological identity and function through human brain connectome mapping.

Сокращение площади льда происходило неравномерно по сезонам года. Показано, что в настоящее время процессы сокращения ледяного покрова летом и его нарастания зимой начали происходить раньше и интенсивнее, чем в 70–80-е годы прошлого столетия.

description: It has been known since the work of Duskin and Pelletier four decades ago that KH^op, the category opposite to compact Hausdorff spaces and continuous maps, is monadic over the category of sets. It follows that KH^op is equivalent to a possibly infinitary variety of algebras V in the sense of Slominski and Linton. Isbell showed in 1982 that the Lawvere-Linton algebraic theory of V can be generated using a finite number of finitary operations, together with a single operation of countably infinite arity. In 1983, Banaschewski and Rosicky independently proved a conjecture of Bankston, establishing a strong negative result on the axiomatisability of KH^op. In particular, V is not a finitary variety--Isbell's result is best possible. The problem of axiomatising V by equations has remained open. Using the theory of Chang's MV-algebras as a key tool, along with Isbell's fundamental insight on the semantic nature of the infinitary operation, we provide a finite axiomatisation of V.

description: Одним из основных вопросов проблемы взаимодействия океана и атмосферы является описание процессов энергомассобмена. В наиболее сложном виде эти процессы представлены в Арктическом бассейне, так как ледяной покров определяет изменение альбедо, потоки тепла и влаги, а также динамическое взаимодействие между океаном и атмосферой. В работе представлены результаты экспериментальных исследований турбулентного взаимодействия атмосферы и морской поверхности в летний и осенний период в центральных и шельфовых зонах Северного Ледовитого океана. Сравнение судовых наблюдений с данными реанализа и мезомасштабного моделирования показывает, что реанализы плохо воспроизводят турбулентные потоки в северной полярной области, особенно в осенний период. Это связано как с недостаточной разработанностью параметризаций для определения коэффициентов обмена в алгоритмах расчета турбулентных потоков, так и со сложностью определения температуры поверхности, покрытой льдом различной сплоченности.

description: One of the main aims of the ESA Rosetta mission is to study the origin of the solar system by exploring comet 67P/Churyumov-Gerasimenko at close range. In this paper we discuss the origin and evolution of comet 67P/Churyumov-Gerasimenko in relation to that of comets in general and in the framework of current solar system formation models. We use data from the OSIRIS scientific cameras as basic constraints. In particular, we discuss the overall bi-lobate shape and the presence of key geological features, such as layers and fractures. We also treat the problem of collisional evolution of comet nuclei by a particle-in-a-box calculation for an estimate of the probability of survival for 67P/Churyumov-Gerasimenko during the early epochs of the solar system. We argue that the two lobes of the 67P/Churyumov-Gerasimenko nucleus are derived from two distinct objects that have formed a contact binary via a gentle merger. The lobes are separate bodies, though sufficiently similar to have formed in the same environment. An estimate of the collisional rate in the primordial, trans-planetary disk shows that most comets of similar size to 67P/Churyumov-Gerasimenko are likely collisional fragments, although survival of primordial planetesimals cannot be excluded. A collisional origin of the contact binary is suggested, and the low bulk density of the aggregate and abundance of volatile species show that a very gentle merger must have occurred. We thus consider two main scenarios: the primordial accretion of planetesimals, and the re-accretion of fragments after an energetic impact onto a larger parent body. We point to the primordial signatures exhibited by 67P/Churyumov-Gerasimenko and other comet nuclei as critical tests of the collisional evolution.

description: The corpus callosum (CC) is the largest connective pathway in the human brain, linking cerebral hemispheres. There is longstanding debate in the scientific literature whether sex differences are evident in this structure, with many studies indicating the structure is larger in females. However, there are few data pertaining to this issue in infancy, during which time the most rapid developmental changes to the CC occur. In this study, we examined longitudinal brain imaging data collected from 104 infants at ages 6, 12, and 24 months. We identified sex differences in brain-size adjusted CC area and thickness characterized by a steeper rate of growth in males versus females from ages 6–24 months. In contrast to studies of older children and adults, CC size was larger for male compared to female infants. Based on diffusion tensor imaging data, we found that CC thickness is significantly associated with underlying microstructural organization. However, we observed no sex differences in the association between microstructure and thickness, suggesting that the role of factors such as axon density and/or myelination in determining CC size is generally equivalent between sexes. Finally, we found that CC length was negatively associated with nonverbal ability among females.

description: Multicomponent superconductivity is a novel quantum phenomenon in many different superconducting materials, such as multiband ones in which different superconducting gaps open in different Fermi surfaces, films engineered at the atomic scale to enter the quantum confined regime, multilayers, two-dimensional electron gases at the oxide interfaces, and complex materials in which different electronic orbitals or different carriers participate in the formation of the superconducting condensate. In all these systems the increased number of degrees of freedom of the multicomponent superconducting wave-function allows for emergent quantum effects that are otherwise unattainable in single-component superconductors.

description: Σκοπός της διατριβής ήταν η παρασκευή φωτοκαταλυτικών υμενίων και η μελέτη των ιδιοτήτων τους. Εξετάσαμε τις μεθόδους με τις οποίες μπορουν τα υμένια αυτά να παρασκευαστούν και τα ειδικά όργανα που απαιτούνται. Επιπλέον, εστιάσαμε στις συνθήκες παρασκευής και πως αυτές επηρεάζουν το τελικό αποτέλεσμα. Στη συνέχεια μελετήσαμε τη δομή και τη μορφολογία των δειγμάτων μέσω της ηλεκτρονικής μικροσκοπίας σάρωσης, καθώς και τις οπτικές ιδιότητες των υμενίων μέσω της χρήσης οπτικού φασματοφωτόμετρου. Ακόμη, μελετήσαμε τις φωτοκαταλυτικές ιδιότητες των υμενίων προσδιορίζοντας τα ενεργειακά τους χάσματα και διεξάγοντας πειράματα αποχρωματισμού. Ασχοληθήκαμε επίσης με τη μελέτη της υδροφιλικότητας των δειγμάτων και διαπιστώσαμε τον υδρόφιλό τους χαρακτήρα.
description: The aim of the present thesis was the fabrication of photocatalytic films and the study of their properties. We examined the methods that can be used to fabricate these films and the specific machines that are required. Moreover, we focused on the conditions of the fabrication and how they affect the final result. Furthermore, we studied the structure and morphology of the samples through scanning electron microscopy, as also the optical properties of the films through the use of an optical spectrophotometer. We studied the photocatalytic properties of the films by calculating their energy band gaps and conducting a decolorization experiment. We also examined the hydrophilicity of the samples and noted their hydrophilic character.

description: Wie können BibliothekarInnen mit ihren informationswissenschaftlichen Kompetenzen AutorInnen dabei unterstützen, ihre Publikationen besser auffindbar zu machen? Die so genannte Academic Search Engine Optimization (kurz: ASEO) ist ein noch wenig beachteter Aspekt beim Vorbereiten eines wissenschaftlichen Manuskripts für die Publikation. Mit einfachen Maßnahmen wie der Wahl aussagekräftiger author keywords können WissenschafterInnen die Sichtbarkeit ihrer Papers in Bibliothekskatalogen, Datenbanken, Repositorien und Suchmaschinen wie Google Scholar erhöhen. Je mehr Daten diesen Suchalgorithmen dabei für die Auswertung eines Datensatzes zur Verfügung stehen, desto höher ist die Wahrscheinlichkeit, dass dieser in einer Trefferliste angezeigt wird. ASEO zielt dabei nicht auf die Manipulation von Suchergebnissen oder Rankings ab, sondern soll Algorithmen von Discovery Systemen und Datenbanken beim automatisierten Erkennen von relevanten Treffern unterstützen. BibliothekarInnen mit ihrem umfangreichen Wissen und Erfahrungsschatz in der Literaturrecherche, Metadatenerfassung und Schlagwortvergabe können hier wertvolle Beratung leisten, welche Rolle korrekte und möglichst vollständige Metadaten sowie passende Stich- und Schlagwörter für Suchalgorithmen und damit für die Anzeige eines Datensatzes bzw. Papers in einer Trefferliste spielen. Auch den Suchenden selbst sollen möglichst viele wichtige Informationen über den Inhalt der Publikation durch eine aussagekräftige Formulierung von Titel und Abstract und die Wahl geeigneter Schlagwörter zur Verfügung gestellt werden. Die für das gesuchte Thema besonders passend und interessant erscheinenden Treffer werden in der oft sehr umfangreichen Ergebnisliste näher angesehen und im besten Fall auch gelesen. Denn das Aufscheinen in einer Trefferliste allein ist nicht ausreichend – nur, wer tatsächlich gelesen wird, hat auch eine Chance, zitiert zu werden. Ziel von ASEO ist daher, sowohl den Suchalgorithmen als auch den LeserInnen eine rasche und eindeutige Identifizierung des Inhalts zu ermöglichen. MitarbeiterInnen der Publikationsservices an der Universität Graz vermitteln im Rahmen ihres Beratungsangebotes die Grundlagen der Auffindbarkeit und praktische Tipps für die Optimierung von Titel, Abstracts, Keywords und Metadaten. Den AutorInnen werden darüber hinaus an Hand ihrer eigenen Publikationen, aber auch mittels vorbereiteten Praxisbeispielen die Möglichkeiten des ASEO aufgezeigt. In diesem Vortrag werden die Entwicklung des Beratungskonzeptes, die Umsetzung sowie eine Einführung in ASEO und die damit verbundenen, in der Publikationsberatung zu vermittelnden Inhalte gegeben. Die Erfahrungen aus diesem neuen Dienstleistungsangebot werden gemeinsam mit den Realisierungsproblemen offen ausgetauscht.

description: Purpose: The association between patients’ shoulder pain and functioning according to the International Classification of Functioning, Disability, and Health (ICF), and outcome on a condition specific patient reported outcome measure (PROM), has not been studied. The aim was to investigate how the most common problems on the ICF checklist were associated with shoulder function and disability. Materials and methods: In a cross-sectional design 164 patients ≥ 18 years with chronic shoulder pain were included. The ICF checklist, the Disability of the Arm, Shoulder, and Hand (DASH) outcome measure and the Self-Report Comorbidity Questionnaire were used. A hierarchical regression model tested categories for functioning on the ICF checklist associated with disability on the DASH. Results: Mean age was 46.5 years, 54% were women. 85% had had the shoulder pain longer than 6 months. Mean DASH score was 33.2 points (SD 17.1). Adjusted R2 was 0.67. Older age, being woman and having a lower education explained 22% of the variance on the DASH. The body functions bodily pain, mobility of joints and energy and drive function explained 30% of the variance, and the activities and participation problems lifting and carrying objects, washing oneself and recreation and leisure explained an additional 13%. Conclusions: The shoulder disability was multi-dimensional and comprised body functions and activities and participation. And 67% of the variance in the DASH score was explained.Implications for rehabilitationPersistent shoulder pain results in multi-dimensional disability calling for a broader assessment of function.A biopsychosocial approach to shoulder pain and disability is recommended.Functioning assessed on the ICF checklist can be applied in the assessment of chronic shoulder pain as it contributes to the understanding of self-reported disability on a region specific outcome measure. Persistent shoulder pain results in multi-dimensional disability calling for a broader assessment of function. A biopsychosocial approach to shoulder pain and disability is recommended. Functioning assessed on the ICF checklist can be applied in the assessment of chronic shoulder pain as it contributes to the understanding of self-reported disability on a region specific outcome measure.

description: This study aimed to investigate the relationship between hormone replacement therapy (HRT) types and breast cancer (BC) incidence in postmenopausal women in Korea. The nested case–control study used data from the National Health Insurance Service database. Among the women aged ≥50 years who menopaused between 2004 and 2007, BC incidence up to 2017 was analyzed in 36,446 women using or having used HRT for >1 year and in 36,446 women who did not use any HRT for more than 1 year. HRT types and duration were classified into three categories. BC risk (BCR) decreased with tibolone use for all ages. With HRT initiation in women aged ≥50 years, BCR was lower with tibolone and estrogen–progestogen therapy. HRT for <3 years showed lower BCR with tibolone, while higher BCR was observed with estrogen-only therapy. BCR was lower in women of all ages on HRT for >5 years than in the control group. For women in their 50s, tibolone use lowers BCR; for all ages, the use of any HRT for >5 years showed lower BCR in Korea. These divergent results from western countries could be associated with the specific characteristics of BC in Korea.
Diagonal Metrics of Static, Spherically Symmetric Fields The Geodesic Equations and the Mass-Energy Relation from the Coordinate Perspective

description: The geodesic equations for the general case of diagonal metrics of static, spherically symmetric fields are calculated. The elimination of the proper time variable gives the motion equations for test particles with respect to coordinate time and an account of gravitational acceleration from the coordinate perspective. The results are applied to the Schwarzschild metric and to the so-called exponential metric. In an attempt to add an account of gravitational force from the coordinate perspective, the special relativistic mass-energy relation is generalized to diagonal metrics involving location dependent and possibly anisotropic light speeds. This move requires a distinction between two aspects of the mass of a test particle (parallel and perpendicular to the field). The obtained force expressions do not reveal gravitational repulsion for the Schwarzschild metric and for the exponential metric.

description: Converging evidence shows that Alzheimer's disease (AD) is a neurodegenerative disease that represents a disconnection syndrome, whereby a large-scale brain network is progressively disrupted by one or more neuropathological processes. However, the mechanism by which pathological entities spread across a brain network is largely unknown. Since pathological burden may propagate trans-neuronally, we propose to characterize the propagation pattern of neuropathological events spreading across relevant brain networks that are regulated by the organization of the network. Specifically, we present a novel mixed-effect model to quantify the relationship between longitudinal network alterations and neuropathological events observed at specific brain regions, whereby the topological distance to hub nodes, high-risk AD genetics, and environmental factors (such as education) are considered as predictor variables. Similar to many cross-section studies, we find that AD-related neuropathology preferentially affects hub nodes. Furthermore, our statistical model provides strong evidence that abnormal neuropathological burden diffuses from hub nodes to non-hub nodes in a prion-like manner, whereby the propagation pattern follows the intrinsic organization of the large-scale brain network.

description: Effective supply chain management (SCM) has become a potentially valuable way of securing competitive advantage through enhancing operational and improving organizational performances since competition is no longer between organizations, but among supply chains. This research conceptualizes and develops five dimensions of SCM practice (strategic supplier partnership, customer relationship, level of information sharing, quality of information sharing, and internal lean practices) and tests the relationships between SCM practices, operational performance, and organizational performance. The data for the study was collected from 80 employees of Yes Natural Spring Water.

description: Peace is much more than the absence of violence. The Campus Gutenberg-CosmoCaixa 2022, held in September in Barcelona, was a unique opportunity to talk about how the communication of science can help generate a true culture for peace. We know that science does not always encourage peace. And, when that happens, what should people who communicate science do? Do we keep quiet or do we let our audience know? Science communicators don’t always choose peace. The Manifesto for responsible communication of science is the result of a debate on these ideas. We believe that science communication can become a tool to help eliminate inequality, injustice, poverty and other threats to peace. But to achieve this, we must take sides and take action. Do you want to join the manifesto?

description: Introduction: The emergency medical services (EMS) system was designed to reduce death and disability and EMS training focuses on saving lives through resuscitation, aggressive treatment and transportation to the emergency department. EMS providers commonly care for patients who have life-limiting illnesses. The objective was to explore EMS provider challenges, self-perceived roles and training experiences caring for patients and families with life-limiting illness. Methods: Qualitative content analysis of semi-structured interviews with EMS providers (n = 15) in Alameda County, CA. Purposive sampling was used to ensure a variety of perspectives including provider age, years of EMS experience, emergency medical technicians and paramedics, fire-based versus private, transport versus non-transporting. Recorded and transcribed interviews were analyzed using a thematic approach. Results: In their work with patients with life-limiting illness, participating EMS providers were interviewed and reported challenges for which their formal training had not prepared them: responding to grief and emotion expressed by families during traumatic events or death notification, and performing in the moment decision-making to determine the course of action after acute, unexpected, and traumatic events. Many participants reported becoming comfortable with grief counseling and death notification after acquiring some clinical experience. In the moment decision-making was eased when patients and families had had advance care planning discussions, however many patients, especially those from vulnerable and underserved populations, lacked advance care planning. In the face of situations where the course of action was not immediately clear, EMS providers voiced two frames for their role in caring for patients with life-limiting illness: transportation only (“transport people”) versus a more “holistic” view, where EMS providers provided counseling and information about available resources. Conclusions: EMS providers interface with patients who have life-limiting illness and their families in the setting of traumatic events where the course of action is often unclear. There is an opportunity to provide formal training to EMS providers around grief counseling as well as how they can assist patients and families in in the moment decision-making to support previously identified goals and align care with patient goals and preferences.
