description: Polychlorinated biphenyls (PCBs) are banned toxic contaminants according to the Stockholm Convention of persistent pollutants (2001); however, they continue to be prevalent in the environment of Pakistan. The current study evaluates the risk to infants exposed to PCBs in breast milk from urban centers of Pakistan. The ∑14PCB concentrations ranged from ND to 118.36 ng/g lipid weight (l.w.) with a mean of 11.76. ± 4.88 ng/g l.w. These levels are greater than concentrations previously reported from Asia. The quantified PCB profile was also significantly (p < .05) related to the age of the mother while a negative correlation was observed with diet pattern (−0.26), fat content (−0.63), number of children (−0.185), and lactation (−0.19). There were significant differences among test locations with greater bioaccumulation observed in breast milk collected from urbanized Rawalpindi compared to less urbanized Jhang. The calculated estimated daily intakes of dioxin-like PCBs for infants were considerably higher than the recommended daily intake suggested by different organizations. The calculated hazard ratio (HR > 1) indicates health risks to infants in selected study regions.

description: To investigate groundwater quality in the north of Jazmourian (Roudbar plain), 30 samples were collected and analyzed for evaluating drinking and irrigation status and associated health risks. In addition to major anions and cations, the fluoride and nitrate content of samples were analyzed using standard procedures. Nitrate levels range between 6.6 and 131 mg/L and exceed the WHO permissible limit in more than 23% and 80% of samples for adults and children, respectively. Fluoride amounts ranged from 0.4 to 4.8 mg/L in samples. The F- level exceeded the WHO standard limit in 10% of samples. The EC level increases in fine-grained deltaic deposits toward the south. The concentrations of major ions (HCO3, Cl, SO4, Mg, Na, K) increase southwards, following the flow direction. There are, however, lateral (east-west) differences in water quality due to the influence of such factors as the rate of recharge and the type of bedrock. Wherever the redbeds comprise the bedrock and the recharge rate is weaker, the dissolved salts are higher in amount. The water quality index (IWQ) indicated that 13, 13, and 4 samples are in “good,” “poor,” and “very poor” quality classes, respectively. By using the irrigation water quality index (IWQI), eight samples were at “low restriction,” nine samples at “moderate restriction,” twelve samples at “high restriction,” and one sample at “severe restriction” classes. The acquired findings revealed that the mean oral hazard quotient of nitrate was 1.14, 1.0, and 0.84, and for fluoride, it was 0.82, 0.72, and 0.61 for children, females, and males, respectively. The total hazard index for cumulative NO3- and F- toxicity exceeded the acceptable level in 76.67%, 66.67%, and 56.67% of samples for children, females, and males, respectively.

description: This article addresses the market-changing phenomenon of the Internet of Things (IoT), which relies on the underlying paradigm of machine-to-machine (M2M) communications to integrate a plethora of various sensors, actuators, and smart meters across a wide spectrum of businesses. The M2M landscape features today an extreme diversity of available connectivity solutions which -- due to the enormous economic promise of the IoT -- need to be harmonized across multiple industries. To this end, we comprehensively review the most prominent existing and novel M2M radio technologies, as well as share our first-hand real-world deployment experiences, with the goal to provide a unified insight into enabling M2M architectures, unique technology features, expected performance, and related standardization developments. We pay particular attention to the cellular M2M sector employing 3GPP LTE technology. This work is a systematic recollection of our many recent research, industrial, entrepreneurial, and standardization efforts within the contemporary M2M ecosystem.

Year: 2007

description: Background: The HIV epidemic continues to be a major problem in sub Saharan Africa. Nearly 70% of the world's HIV-1 seropositive individuals live in sub Saharan Africa. Several factors are thought to be unique to the HIV epidemic in sub Saharan Africa. The prevalence is higher than other parts of the world, clinical co-infections are seen frequently, women are infected at higher prevalence rates in comparison to men and the disease progresses more rapidly. Of the different co-infections that occur among HIV-1 seropositive individuals, genital ulcer disease (GUD) has been shown to be associated with HIV-1 infection. It is thought that GUD increases infectivity, transmissibility and acquisition of HIV-1. GUD is also of concern since its prevalence in sub Saharan Africa continues to rise. Understanding the relationship between HIV-1 infection and GUD could help create policies which may more effectively contain and reduce the spread of the HIV-1 pandemic. Methods: A systematic review was performed to evaluate the current body of literature regarding GUD co-infections among adult females in sub Saharan Africa with HIV-1. It was hypothesized that a higher prevalence rate of GUD would be seen among females of lower SES and younger age groups. Additionally, analysis was conducted using a secondary data set of 371 Malawians who were followed for 13 months. Univariate analyses were conducted to calculate prevalence rates of GUD. Bivariate analyses were conducted to assess differences in GUD prevalence by gender and HIV status using Chi-square tests. Kaplan Meier survival time models were used to calculate incidence rates for GUD. It was thought that higher rates of GUD would be seen among women and HIV-1 seropositive individuals. Results Within the Malawian cohort that was studied, the incidence rate for GUD among men was 5.33 cases per 100,000 person years while the incidence rate among women was 20.12 cases per 100,000 person years. The incidence rate of GUD among HIV-1 seropositve and seronegative individuals was 8.98 cases per 100,000 person years and 8.02 cases per 100,000 person years, respectively. Among individuals who were HIV-1 seropositive, 3,811 clinical diagnoses were made in the 13 month period while 1,983 Interpretation Among this Malawian cohort, it appears that the incidence rate of GUD among women is higher and that among men. Additionally, HIV-1 seropositive individuals were given more clinical diagnoses compared to HIV-1 seronegative individuals.

description: PM10 levels, concentrations of trace metals, source apportionment, and potential health risks exposed to PM10-bound metals via inhalation pathway were investigated at industrial, traffic and residential sites in Bac Giang, Vietnam. The average PM10 concentration exhibited the highest value at the industrial sites, followed by the traffic sites, and the residential sites. The PM10 mass was 1.38 to 3.39 times higher than the National Air Quality Standard (QCVN 05:2013/BTNMT) (150 µg/m3 for 24 h). The concentrations of non-crustal trace elements (As, Cd, Cr, Ni, Pb, V, and Zn) at industrial sites were at a higher level than at the traffic and residential sites. Enrichment Factors analysis and principal component analysis (PCA) were performed for source apportionment of PM10 in Bac Giang. Four potential emission sources including traffic-related emissions, industry, use of pesticides, and coal combustion were identified. The results of pollution load index and health risk assessments showed higher contamination levels and higher non-carcinogenic and carcinogenic risks posed to children and adults in the vicinity of the industrial sites than the traffic and residential sites. The HQ value for Cr greater than 1 at industrial sites expressed the adverse health effects among humans should be a concern. Further, the health risk of adults exposed to toxic elements via inhalation contact was more pronounced than the children at all sampling sites.

description: The Voyager probes are the furthest, still active, spacecraft ever launched from Earth. During their 38-year trip, they have collected data regarding solar wind properties (such as the plasma velocity and magnetic field intensity). Unfortunately, a complete time evolution of the measured physical quantities is not available. The time series contains many gaps which increase in frequency and duration at larger distances. The aim of this work is to perform a spectral and statistical analysis of the solar wind plasma velocity and magnetic field using Voyager 2 data measured in 1979, when the gaps/signal ratio is of order of unity. This analysis is achieved using four different data reconstruction techniques: averages on linearly interpolated subsets, correlation of linearly interpolated data, compressed sensing spectral estimation, and maximum likelihood data reconstruction. With five frequency decades, the spectra we obtained have the largest frequency range ever computed at 5 astronomical units from the Sun; spectral exponents have been determined for all the components of the velocity and magnetic field fluctuations. Void analysis is also useful in recovering other spectral properties such as integral scales (see for instance Table 4) and, if the confidence level of the measurements is sufficiently high, the decay variation in the small scale range due, for instance, to dissipative effects.

Mental Health & Psychosocial Support for Syrian Refugees in Jordan – A Capacity Analysis of the national implementation of WHO’s mhGAP
Creators: name: Schubert, Johanna
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: With 659,063 registered refugees, the Hashemite Kingdom of Jordan is one of the top three safe havens for Syrian refugees since the war in Syria escalated and forced a current total of 5.6 million Syrians out of their homes by March 2018 (UNHCR, 2018). In addition to the pre-war prevalence of mental disorders, traumatic stress and stress-related Mental Health (MH) issues pose an increasing challenge on the Mental Health and Psychosocial Support (MHPSS) system in Jordan, which is still an underdeveloped sector with limited capacity and many challenges. WHO’s Mental Health Gap Action Plan (mhGAP; WHO, 2008) aims to provide governments and organizations with guidelines on how to strengthen the capacity of their Mental Health Services (MHS) Systems. Based on mhGAP, the Jordanian Government developed a comprehensive Mental Health Policy Plan to master the challenge. This policy analysis aims to assess the status quo of the mhGAP capacity in Jordan in order to formulate policy recommendations to support the process of MH Capacity Development in Jordan targeting refugees as particularly vulnerable population segment. Key focus of recommendation lies on the alignment and harmonization of donor and NGO efforts in the Mental Health Sector, the strengthening and decentralization of the national MH workforce increasingly including female health workers, while establishing a centralized monitoring and evaluation system to increase governmental ownership and oversight. Semi-Conditional cash transfers requiring refugee beneficiaries to attend regular meetings with psychosocially versed case managers in order to retrieve unconditional payments would alleviate existential pressures and therefore sources of stress and therefore mental health burden, especially for families with children. Psychoeducation programs to raise awareness among both refugee and local populations in order to reduce stigma is essential to increase health services utilization once capacities are developed.

description: Immer neue Publikationsplattformen mit unterschiedlichsten Funktionalitäten und Zielen entstehen und bieten ihre Services an. Viele Ansätze bilden dabei ein Gegengewicht zu den “klassischen” Abläufen im Verlagswesen. Die Einbeziehung von Preprints, die Verknüpfung unterschiedlicher Forschungs-Outputs (wie Daten, Laborprotokolle oder Softwarecode), offene Begutachtungsverfahren oder neue Geschäftsmodelle sind nur einige Aspekte, die von den unterschiedlichen Plattformen adressiert werden. Im Rahmen einer Task and Finish Group von Knowledge Exchange (KE) wird eine Taxonomie über solche alternativen Publikationsplattformen erstellt. Diese Taxonomie soll dabei helfen, einen besseren Überblick über die diversen Plattformen zu erhalten und sie sichtbarer zu machen. Der erste Schritt der T&F Group war die Erstellung eines Scoping-Papers ( https://doi.org/10.21428/996e2e37.3ebdc864 ), in dem sich diesem Thema genähert wurde. Das Dokument selbst ist auf der “alternativen” Plattform PubPub entstanden, die eine aktive Mitarbeit der Community erlaubt und die Versionierung des Dokuments übernimmt. Im Frühjahr 2023 hat die T&F Group zur Beteiligung an einer Umfrage aufgerufen, um in einem zweiten Schritt eine Taxonomie der unterschiedlichen Plattformen zu erstellen. Die Umfrage richtete sich an alle Plattformen, die im Bereich des Open-Access-Publizierens tätig sind und in die Taxonomie der alternativen Publikationsplattformen von der Knowledge Exchange aufgenommen werden möchten. Der Vortrag beleuchtet die verschiedenen Wege alternativer Publikationsplattformen und präsentiert erste Ergebnisse aus der Umfrage und gibt somit einen Ausblick auf die angestrebte Taxonomie.

description: When a drop of water is placed on a rough surface, there are two possible extreme regimes of wetting: the one called Cassie-Baxter (CB) with air pockets trapped underneath the droplet and the one characterized by the homogeneous wetting of the surface, called the Wenzel (W) state. A way to investigate the transition between these two states is by means of evaporation experiments, in which the droplet starts in a CB state and, as its volume decreases, penetrates the surface's grooves, reaching a W state. Here we present a theoretical model based on the global interfacial energies for CB and W states that allows us to predict the thermodynamic wetting state of the droplet for a given volume and surface texture. We first analyze the influence of the surface geometric parameters on the droplet's final wetting state with constant volume, and show that it depends strongly on the surface texture. We then vary the volume of the droplet keeping fixed the geometric surface parameters to mimic evaporation and show that the drop experiences a transition from the CB to the W state when its volume reduces, as observed in experiments. To investigate the dependency of the wetting state on the initial state of the droplet, we implement a cellular Potts model in three dimensions. Simulations show a very good agreement with theory when the initial state is W, but it disagrees when the droplet is initialized in a CB state, in accordance with previous observations which show that the CB state is metastable in many cases. Both simulations and theoretical model can be modified to study other types of surface.

Motivators for enrollment and completion of pregnancy outcomes research: A comparison of African-American and Caucasian women's perspectives
Creators: name: Beamon, Carmen J.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Women and minority populations, specifically African-Americans, continue to be under represented in medical research. The exclusion of women and minorities from clinical trials raises questions about whether treatment outcomes are generalizable to these populations and about equity in the provision of health care. Despite the recognition of the need to include women and minorities in medical research, many factors limit their participation. This study explored the motivators for participation, retention and satisfaction of reproductive-aged women who participated in the Right from the Start Study (RFTS), an ongoing, prospective study of early pregnancy risk factors for spontaneous abortion and preterm birth. The goal was to improve our understanding of factors important to participation in pregnancy-outcomes research, and to determine if these factors varied between African-American and white women. Three focus groups, two with African-American women and one with white women, were conducted to learn about the women's opinions on participation in pregnancy outcomes research. The majority of the women in all focus groups indicated that facilitative aspects of the study, such as free ultrasounds and pregnancy tests were the most important reason for participating in the RFTS study. However, factors influencing retention and satisfaction with research differed between the racial groups. Interest in the research topic, familial altruism and personal relevance were the major themes expressed by the African-American women; whereas, Caucasian women were motivated by commitment, convenience and reimbursement. By using the themes that emerged from these focus groups in combination with the literature on participation and retention in medical research, the design of future research trials involving reproductive-aged women can be improved to reflect better understanding of the factors affecting enrollment, retention and satisfaction with research. We speculate that all studies involving reproductive-aged women, and especially African-American women, should focus on improving and emphasizing individual benefits of participation. Research designed to study reproductive-aged women should include components that are purposeful to the participant, such as tests that the participant values, and should employ staff who are friendly and compassionate. If the barriers known to impede participation are lessened while factors that improve satisfaction and enrollment are enhanced, the participation and retention of women in future trials can be ensured.
Law Enforcement Based Motor Vehicle Injury Prevention Programs

description: Injuries continue to be a large public health burden for most populations in the United States (US). In 2005 alone, motor vehicle crashes were responsible for 43,667 deaths and 37% of unintentional injury deaths (Centers for Disease Control and Prevention [CDC], 2008). According to the CDC website, motor vehicle injuries are also problematic for the American Indian (AI) population. Motor vehicle crashes and pedestrian-related injury were the leading causes of unintentional injury-related death among AI adults 20 years and older. Adult motor vehicle-related death rates for AIs were more than twice that of whites and almost twice that of blacks (CDC, 2007). Tribal law enforcement based motor vehicle injury prevention programs have been very successful in addressing motor vehicle injuries and deaths in AI communities (Reede, Piontkowski, Tsatoke, 2007). This study explores comprehensive law enforcement based motor vehicle injury prevention programs. The objectives of this study were three-fold: to identify the process, key elements, and challenges for establishing comprehensive law enforcement based motor vehicle injury prevention programs. This information will be especially helpful to local public health agencies (LPHAs) choosing to collaborate with law enforcement given that it is now recommended that public health strengthen partnerships and collaborations in road safety to further reduce and prevent motor vehicle injuries (Dellinger, Sleet, Shults, and Rinehart, 2007).

description: Objective: To determine the synergistic effects of nutrition, specifically adherence to the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet, and physical activity on cognition and brain outcomes in a cross-sectional healthy aging cohort. Methods: A total of 132 adults (age range 52–91; Clinical Dementia Rating = 0) from the UCSF Brain Aging Project completed a 15-item MIND diet food frequency questionnaire and an 11-item self-report measure of weekly physical activity (Physical Activity Scale [PASE]). Cognitive outcomes included executive functioning, episodic memory, and language. Neuroimaging outcomes consisted of total grey matter volume and total white matter volume, adjusted for total intracranial volumes. All regression interaction models adjusted for age, sex, education, and a composite vascular burden score. Results: There was a significant interaction between PASE and MIND on executive functioning and total grey matter volume. Low levels of both related to disproportionately poorer cognitive and brain structural outcomes. Increasing levels of either, but not both, PASE or MIND related to better executive functioning and gray matter outcomes. For memory, language, and total white matter volume, the interaction between PASE and MIND showed the same directionality but did not reach statistical significance. Conclusions: Higher levels of physical activity associated with better executive functioning and gray matter volume, particularly when diet was poor. Similarly, higher levels of MIND diet adherence were associated with better brain and cognitive outcomes when physical activity was low. However, highest levels of physical activity and MIND diet together did not necessarily lead to disproportionately better cognitive and brain volume outcomes.

description: To determine the longitudinal trajectories and normative standards of episodic memory in older adults. Participants were drawn from the cognitively normal(CN) subgroup of the population-based HELIAD cohort, a fairly representative cohort of the older Greek population. Verbal and non-verbal memory were assessed using the Greek Verbal Learning Test and Medical College of Georgia-Complex Figure Test. Baseline and longitudinal associations of memory performance with age, sex and formal education were explored with linear regression analysis and generalized estimated equations. A total of 1607 predominantly female (60%) individuals (73.82 ± 5.43 years), with a mean educational attainment of 8.17(±4.86) years were CN at baseline. Baseline analysis revealed a continuum of memory decline with aging and lower educational attainment. Women performed better in composite and verbal memory measures, while men performed better in non-verbal memory tasks. A subgroup of 761 participants with available assessments after 3.07(±0.82) years remained CN at follow-up. Composite memory scores yearly diminished by an additional 0.007 of a SD for each additional year of age at baseline. Regarding verbal learning, immediate free verbal recall, delayed free verbal recall and delayed cued verbal recall, an additional yearly decrease of 0.107, 0.043, 0.036 and 0.026 words were respectively recorded at follow-up, for each additional year of age at baseline. Women underwent steeper yearly decreases of 0.227 words in delayed cued verbal recall. No significant longitudinal associations emerged for immediate non-verbal memory, delayed non-verbal memory and immediate cued verbal recall. In the present study, aging (but not educational attainment) was consistently associated with steeper verbal memory decline.

Energy output from a single outer hair cell

description: Electromotility of outer hair cells (OHCs) has been extensively studied with in vitro experiments because of its physiological significance in the cochlear amplifier, which provides the exquisite sensitivity and frequency selectivity of the mammalian ear. However, these studies have been performed largely under load-free conditions or with static load, while these cells function in vivo in a dynamic environment, receiving electrical energy to enhance mechanical oscillation in the inner ear. This gap leaves uncertainties in addressing a key issue, how much mechanical energy an OHC provides. The present report is an attempt of bridging the gap by introducing a simple one-dimensional model for electromotility of OHC in a dynamic environment. This model incorporates a feedback loop involving the receptor potential and the mechanical load on OHC, and leads to an analytical expression for the membrane capacitance, which explicitly describes the dependence on the elastic load, viscous drag, and the mass. The derived equation of motion was examined in a mass-less model system with realistic parameter values for OHC. It was found that viscous drag is more effective than elastic load in enhancing the receptor potential that drives the cell. For this reason, it is expected that OHCs are more effective in counteracting viscous drag than providing elastic energy to the system.

In the wake of this massive outbreak, and cognizant of the fact that once-exotic foreign diseases are but a plane flight away from American shores, many jurisdictions crafted EVD response plans. Alaska was among these jurisdictions, although the state’s culture, demographics, geography, and climate created many challenges, presented some unique opportunities, and necessitated the inclusion of many customized response elements. A problem potentially greater than EVD surrounds the possibility that a future outbreak might be caused by an airborne infectious disease (AID). These diseases, with their propensity for transmission via droplet nuclei, might prove far more contagious than EVD and pose the risk of rapid widespread secondary transmission. In light of this, Alaska now seeks to create an AID concept of operations (ConOps) plan in order to guide the response to these important diseases of high morbidity and mortality. In order to inform the drafting of this ConOps plan, we undertook a broad literature review, conducted survey-based community needs assessments of clinical entities, as well as commercial fisheries, and visited several Alaskan facilities. We report here the results of these studies, discuss certain key policy development considerations, and detail some of the important elements of the ConOps plan.

description: Several approximations are made to study the microcanonical formalism that are valid in the thermodynamics limit. Usually it is assumed that: 1)Stirling approximation can be used to evaluate the number of microstates; 2) the surface entropy can be replace by the volumen entropy; and 3)derivatives can be used even if the energy is not a continuous variable. It is also assumed that the results obtained from the microcanonical formalism agree with those from the canonical one. However, it is not clear if these assumptions are right for very small systems (10-100 particles). To answer this questions, two systems with exact solutions (the Einstein model of a solid and the two-level system)have been solve with and without these approximations.

description: In Fall 2016, the Office of Planning, Research and Evaluation in the Administration for Children and Families, U.S. Department of Health and Human Services (OPRE), in collaboration with the Health Resources and Services Administration (HRSA), awarded the Urban Institute a contract to study the state of the home visiting workforce. The project examines the characteristics, qualifications, and career trajectories of home visiting staff and strategies to build a pipeline of qualified home visitors and supervisors. The project includes two major components: 1) a national survey of the home-visiting workforce, including home visitors, supervisors, and program managers, in local agencies receiving funding from the Maternal, Infant, and Early Childhood Home Visiting (MIECHV) program, and 2) case studies of eight distinct sites, involving semi-structured interviews with program leaders and supervisory staff, as well as focus groups with home visitors. Together, these research approaches will address critical research questions including: 1. What are the characteristics of home visitors and their supervisors, including their demographics, qualifications, and employment history? 2. What are the characteristics of home visiting jobs? a. What schedules do staff work? How flexible and predictable are their schedules? b. How much do staff earn? How do job earnings vary by degree and position? c. How do employee compensation and benefits compare to other fields? 3. What are the career pathways of home visitors and supervisors? a. Why do home visitors enter this field? b. What are home visitors’ career goals and perceptions of advancement opportunities? c. What factors contribute to the recruitment, retention, and turnover of home visitors? 4. What strategies do programs use to recruit and retain staff? a. What are program managers’ experiences recruiting qualified job candidates? b. What competencies are they looking for? What positions are challenging to fill and why? 5. What opportunities and challenges exist for professional development and training? a. What training needs does the workforce perceive? The study will result in several written products and dissemination activities that share key themes and findings related to the career trajectories of home visitors and their supervisors.

description: Die Metadatenallmende ist ein wichtiger Baustein für den Wandel hin zu einem diversen Open-Access-Ökosystem. Nur mit offenen und hochwertigen Metadaten, die mindestens die gleiche oder sogar höhere Qualität und Abdeckung als die Metadaten-Silos etablierter kommerzieller Verlage erreichen, können unabhängige Zeitschriften auf Augenhöhe Themen wie Auffindbarkeit und faire Evaluation von Forschenden angehen. Wir stellen einen Arbeitsablauf und Werkzeuge vor, die eine Professionalisierung der Metadatenprozesse von unabhängigen, scholar-led OA-Journals unterstützen. Diese Journals können damit ihre Sichtbarkeit im Wissenschaftssystem und ihre Bedeutung als Publikationsort erhöhen. Dazu wird die global verbreitete Free and Open Source Software (FOSS) Open Journal Systems (OJS) um Funktionen erweitert, die a) Eingabe, Kuratierung und Anreicherung von artikelbezogenen Metadaten durch Autor:innen und Editor:innen und b) den Export dieser Metadaten an offene Datenquellen wie z. B. Wikidata ermöglichen. Diese Erweiterung wird durch OJS-Plugins und auch Anpassung der OJS-Kernsoftware in den folgenden Anwendungsfällen umgesetzt: Erstens ermöglicht die Integration von validierten persistenten Identifikatoren (PIDs) und geographischen Metadaten als Teil der Publikationsmetadaten eine bessere Auffindbarkeit und von Artikeln aus Open-Access-Zeitschriften. PIDs und Geometadaten stellen Verbindungen zu anderen Publikationen, akademischen Events, physischen Proben und wissenschaftlichen Instrumenten her und verknüpfen so verwandte Artikel über Zeitschriften und Wissenschaftsdisziplinen hinweg. Auf Basis dieser Metadaten werden zum Beispiel eine Suchplattform realisiert, die wissenschaftliche Artikel über Disziplingrenzen und Publikationsplatformen hinweg als offene Daten interaktiv auf einer Karte darstellt, und semantisch bedeutsame Links in Artikeln und ihren Landing Pages eingefügt. Zweitens werden Zitationsmetadaten während des Einreichungs- und Begutachtungsprozesses strukturiert erfasst und frei in standardisierten Formaten veröffentlicht. Durch die innovative und benutzerfreundliche Metadatenerfassung im Zuge des wissenschaftlichen Ver­öffentlichungsprozesses können Open-Access-Artikel in transparenten zitationsbasierten Evaluationsmetriken verwendet werden. Diese Neuerungen unterstützen eine offene Publikationskultur und -praxis. In diesem Beitrag berichten wir vom aktuellen Arbeitsstand zu den Anwendungsfällen und beschreiben eine Vision für eine neuartige verteilte Erfassung und Veröffentlichung offener Metadaten.

description: Objective: To determine the synergistic effects of nutrition, specifically adherence to the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet, and physical activity on cognition and brain outcomes in a cross-sectional healthy aging cohort. Methods: A total of 132 adults (age range 52–91; Clinical Dementia Rating = 0) from the UCSF Brain Aging Project completed a 15-item MIND diet food frequency questionnaire and an 11-item self-report measure of weekly physical activity (Physical Activity Scale [PASE]). Cognitive outcomes included executive functioning, episodic memory, and language. Neuroimaging outcomes consisted of total grey matter volume and total white matter volume, adjusted for total intracranial volumes. All regression interaction models adjusted for age, sex, education, and a composite vascular burden score. Results: There was a significant interaction between PASE and MIND on executive functioning and total grey matter volume. Low levels of both related to disproportionately poorer cognitive and brain structural outcomes. Increasing levels of either, but not both, PASE or MIND related to better executive functioning and gray matter outcomes. For memory, language, and total white matter volume, the interaction between PASE and MIND showed the same directionality but did not reach statistical significance. Conclusions: Higher levels of physical activity associated with better executive functioning and gray matter volume, particularly when diet was poor. Similarly, higher levels of MIND diet adherence were associated with better brain and cognitive outcomes when physical activity was low. However, highest levels of physical activity and MIND diet together did not necessarily lead to disproportionately better cognitive and brain volume outcomes.

description: Shortly after the determination of the first protein x-ray crystal structures, researchers analyzed their cores and reported packing fractions $ϕ\approx 0.75$, a value that is similar to close packing equal-sized spheres. A limitation of these analyses was the use of `extended atom' models, rather than the more physically accurate `explicit hydrogen' model. The validity of using the explicit hydrogen model is proved by its ability to predict the side chain dihedral angle distributions observed in proteins. We employ the explicit hydrogen model to calculate the packing fraction of the cores of over $200$ high resolution protein structures. We find that these protein cores have $ϕ\approx 0.55$, which is comparable to random close-packing of non-spherical particles. This result provides a deeper understanding of the physical basis of protein structure that will enable predictions of the effects of amino acid mutations and design of new functional proteins.
